MODES FOR CARRYING OUT THE INVENTION
[0092] Hereinafter, a pouch according to exemplary embodiments of
the present invention will be described in detail with reference to
accompanying drawings.
First Exemplary Embodiment
[0093] As shown in FIGS. 1 to 3, a pouch 200 according to a first
exemplary embodiment includes a contents-accommodating section 210
having a contents-accommodating space S1 for accommodating
contents; a temperature controller 220 placed in at least one side
between a front side and a rear side with respect to the
contents-accommodating section 210 in order to heat or cool the
contents-accommodating section 210; and a sealing portion 230
sealing up a liquid reactant entrance 222 communicating with
temperature control spaces S2, S3 inside the temperature controller
220.
[0094] Here, the contents may include food such as boiled rice,
Bibimbap, soup, stew or dry milk; a pad containing medicine for
taking a hot massage or a cold massage, or a mask pad containing
beauty ingredients. Besides, the contents may be varied as long as
it has to be instantly heated or cooled.
[0095] The contents-accommodating section 210 includes a first
front film 211 and a first back film 213 placed in front and back
to form the contents-accommodating space S1.
[0096] The first front film 211 and the first back film 213 may be
made of a plastic film. In more detail, the plastic film may
include polyethylene (PE), polypropylene (PP), or a polyethyelene
terephthalate (PET). Besides, the first front film 211 and the
first back film 213 may be made of well-known synthetic resin films
of various materials.
[0097] The temperature controller 220 couples with the
contents-accommodating section 210, in more detail, couples with
the contents-accommodating section 210 so as to form the
temperature control spaces S2, S3 provided in at least one side
between the front and rear sides with respect to the
contents-accommodating space S1.
[0098] FIGS. 1 to 3 illustrate that the temperature control spaces
S2, S3 are formed in front and back, but not limited thereto. As
necessary, the temperature control spaces S2, S3 may be formed at
only one side.
[0099] The temperature controller 220 includes a second front film
221 coupled in the front of the contents-accommodating section 210
and forming the temperature control space S2 in a front side; and a
second back film 224 coupled in the back of the
contents-accommodating section 210 and forming the temperature
control space S3 in a back side.
[0100] The second front film 221 and the second back film 224 made
of a plastic film such as polyethylene (PE), polypropylene (PP), or
a polyethyelene terephthalate (PET). Besides, the second front film
221 and the second back film 224 may be made of well-known
synthetic resin films of various materials.
[0101] Here, the temperature control spaces S2, S3 are isolated
from the contents-accommodating space S1.
[0102] The front and back temperature control spaces S2, S3 can
communicate with each other through a communication space S4. The
communication space S4 may be formed by arranging the
contents-accommodating section 210 so that the lower end portion
211c of the contents-accommodating section 210 can be spaced apart
from the lower end portion C1 of the temperature controller 220. In
this case, the lower end portion C1 of the temperature controller
220 is a part where the respective lower end portions of the second
front film 221 and the second back film 224 are coupled by
ultrasonic waves or thermal welding. Of course, coupling between
the plastic films may be achieved various well-known methods
besides the foregoing ultrasonic waves or thermal welding.
[0103] Meanwhile, the contents-accommodating section 210 and the
temperature controller 220 may be coupled with each other at left
and right end portions C1, C2 by ultrasonic waves or thermal
welding.
[0104] The temperature controller 220 includes a plurality of
temperature control agents 223, 225 respectively arranged in the
plurality of temperature control spaces S2, S3.
[0105] As described above, if the temperature control spaces S2, S3
are formed at only one side between front and back sides, the
temperature control agents 223, 225 may be arranged at only one
corresponding side.
[0106] Here, the temperature control agents 223, 225 includes
heating elements 223a, 225a to exothermically react with the liquid
reactant, and absorption fabrics 223b, 225b surrounding the heating
elements 223a, 225a and absorbing the liquid reactant to make the
exothermic reaction smoothly.
[0107] As necessary, the absorption fabrics 223b, 225b may be
omitted.
[0108] Also, a heat absorption agent endothermically reacting with
the liquid reactant may be used instead of the heating elements
223a, 225a. The heating element and the heat absorption agent react
with the liquid reactant to heat and cool the contents accommodated
in the contents-accommodating space S1.
[0109] The heating element may include at least one among calcium
oxide, calcium hydroxide, magnesium chloride, iron, and aluminum.
Of course, the foregoing substances may be replaced or changed by
other substances as long as it can react with the liquid
reactant.
[0110] The heat absorption agent may include at least one of
ammonium nitrate (NH4NO3), sodium acetate and urea.
[0111] Here, the plurality of temperature control agents 223, 225
may all include only the heating elements, or only the heat
absorption agent.
[0112] As necessary, in the plurality of temperature control agents
223, 225, the front temperature control agent 223 may include only
the heating element, and the back temperature control agent 225 may
include only the heat absorption agent. In this case, the front and
back temperature control spaces S2, S3 may not communicate with
each other but isolated from each other with the
contents-accommodating space S1 therebetween.
[0113] The temperature controller 220 may further include a liquid
reactant entrance 222 through which the liquid reactant is put into
the temperature control spaces S2, S3.
[0114] The liquid reactant entrance 222 is to put the liquid
reactant capable of reacting with the temperature control agents
223, 225.
[0115] The liquid reactant entrance 222 is sealed up but openable
in the sealing portion 230 to be described later.
[0116] Also, the liquid reactant entrance 222 is arranged at a
lower side of the contents-accommodating section 210 rather than an
upper end thereof. That is, an upper edge of the liquid reactant
entrance 222 is lower than the upper end of the
contents-accommodating section 210 so that a user can easily check
the position of the liquid reactant entrance 222 with his/here
naked eyes.
[0117] The liquid reactant entrance 222 may be formed as a partial
upper end section G of the second front film 221 of the temperature
controller 220 is not coupled with the first front film 211. At
this time, the second front film 221 of the remaining upper end
section C3 may be permanently sealed up with the first front film
211.
[0118] Here, the drawings illustrate the liquid reactant entrance
222 is formed in the partial upper end section G of the second
front film 221. As necessary, the liquid reactant entrance 222 may
be formed in the entire upper end section of the second front film
221.
[0119] Also, the height of the liquid reactant entrance 222 from
the lower end of the pouch may be relatively greater than that of
the remaining section C3 of the second front film 221 from the
lower end of the pouch. Of course, the liquid reactant entrance 222
may have the same height as the remaining section C3 of the second
front film 221.
[0120] The liquid reactant entrance 222 may include a grip portion
extended frontward to be griped by a user's hand. Thus, a user can
easily open the liquid reactant entrance 222.
[0121] Here, the grip portion 222a may be as shown in FIG. 3 formed
to be folded down from the first front film 211.
[0122] As necessary, instead of the grip portion 222a of FIG. 3,
the upper end of the second front film 221 may be as shown in FIG.
4 provided as it is spaced from the contents-accommodating section
210, specifically from the first front film 211 by a predetermined
space K. Thus, a user puts his/her fingers in the space K and
broadens the liquid reactant entrance 222, thereby opening the
liquid reactant entrance 222.
[0123] Meanwhile, the sealing portion 230 seals up the liquid
reactant entrance 222. Thus, it is possible to prevent foreign
materials from entering the liquid reactant entrance 222 while the
contents is put into and sterilized in the contents-accommodating
section S1 of the pouch 200. Such sterilization is essential when a
retort pouch is produced by putting stew, soup, boiled rice and the
like instant foods into the pouch 200.
[0124] Accordingly, the pouch 200 according to an exemplary
embodiment facilitates the manufacture of the retort pouch.
[0125] As shown in FIG. 3, the sealing portion 230 may be provided
between the second front film 221 and the first front film 211 at a
side lower than the grip portion 222a of the liquid reactant
entrance 222.
[0126] The sealing portion 230 may be provided to allow opening
between the first front film 211 and the second front film 221 when
force of not less than a predetermined magnitude is applied
thereto. In other words, if external force of not less than a
predetermined magnitude is applied, the sealing portion 230 may
open the liquid reactant entrance 222. Thus, if a user grips and
then pulls the grip portion 222a by force of not less than a
predetermined magnitude, the liquid reactant entrance 222 is
opened.
[0127] A user puts the liquid reactant (for example, water) into
the opened liquid reactant entrance 222, thereby heating or cooling
the contents accommodated in the contents-accommodating space
S1.
[0128] In particular, it is convenient for a user because the
liquid reactant entrance 222 is easily opened to put the liquid
reactant therein.
[0129] The sealing portion 230 may include an adhesive or a
double-sided tape. As necessary, the sealing portion 230 may be
formed by fusing the first front film 211 and the second front film
221 through thermal welding or ultrasonic waves. At this time, the
first front film 211 and the second front film 221 may be fused to
such an extent as to be separated from each other when the sealing
portion 230 receives external force of a predetermined
magnitude.
[0130] Of course, the sealing portion 230 may be varied as long as
it can seal up the liquid reactant entrance and prevent foreign
materials, such as liquid (e.g., water), from being introduced
therein if there is no external force of not less than a
predetermined magnitude.
[0131] Meanwhile, the pouch 200 may further include a ziplock 260
to selectively seal up the upper portion of the
contents-accommodating section 210.
[0132] The ziplock 260 includes a female zipper 261 formed inside
the first front film 211 and a male zipper 263 formed inside of the
first back film 213. Of course, the positions of the female zipper
261 and the male zipper 263 may be exchanged.
[0133] Also, various well-known sealing means may be employed
instead of the ziplock 260 as long as it can selectively seal up
the contents-accommodating section 210.
[0134] Meanwhile, the pouch 200 may further include a transparent
window 215, 216, 217 for checking whether the
contents-accommodating space S1 is sealed up or not. That is, the
defect of the contents-accommodating section 210 can be determined
by naked eyes through the transparent windows 215, 216, 217.
[0135] As shown in FIG. 1, the transparent window 215 may be
arranged between the liquid reactant entrance 222 and the upper end
of the first front film 211. Through the transparent window 215,
contact between the first front film 211 and the contents
accommodated therein is checked by naked eyes, and it is thus
possible to determine whether a product is defective or not. For
example, if solid food is put into the contents-accommodating
section 210 and then the contents-accommodating space S1 is
vacuumized, it is possible to determine by naked eyes through the
transparent window 215 whether there is a trouble in the
vaccumization.
[0136] Meanwhile, the transparent window 216 may be as shown in
FIGS. 1 and 2 formed in a lower portion of the pouch 200. If the
contents accommodated in the contents-accommodating section 210 is
liquid and the liquid leaks out because the contents-accommodating
section 210 is defective, it is possible to determine by naked eyes
through the transparent window 216 of the lower portion whether the
product is defective or not. To make it easier to determine through
the transparent window 216 of the lower portion whether the
contents-accommodating section 210 is sealed up or not, a
corresponding region of the second front film 221 formed with the
transparent window 216 may be transparently formed, but a
corresponding region of the first front film 221 may be opaque. For
example, the second front film 221 may be entirely made of a
transparent film, while the first front film 221 may be entirely
made of an opaque film.
[0137] Also, the transparent window 217 formed in a vertical
direction may be as shown in FIG. 1 formed at one side between left
and right sides of the pouch 200 along a lengthwise direction.
Thus, a user leans the pouch 200 and checks by his/her naked eyes
through the transparent window 217 whether the contents
accommodated in the contents-accommodating section 210 leak out or
not, thereby determining whether a product is defective or not.
[0138] The plurality of transparent windows 215, 216, 217 are to
check whether the contents-accommodating space S1 of the
contents-accommodating section 210 is surely isolated from the
temperature control spaces S2, S3. If it is checked through the
plurality of transparent windows 215, 216, 217 that there is no
defect in a product, the contents of the contents-accommodating
space S1 is not affected by a byproduct produced by the exothermic
or endothermic reaction within the temperature control spaces S2,
S3.
[0139] The drawings show the plurality of transparent windows 215,
216, 217, but the number and positions of the transparent windows
215, 216, 217 may be varied.
[0140] Meanwhile, the foregoing description illustrates that the
liquid reactant entrance 222 is formed at only one side between the
front and back sides, but not limited thereto. Alternatively, the
liquid reactant entrance 222 may be formed at both the front and
back sides.
Second Exemplary Embodiment
[0141] Meanwhile, a pouch 200a according to the second exemplary
embodiment may as shown in FIG. 5 include a contents-accommodating
section 210a, a temperature controller 220 and a sealing portion
230.
[0142] The contents-accommodating section 210a of the pouch 200
according to the first exemplary embodiment has the lower end 211c
spaced apart from the lower end of the temperature controller 220
as shown in FIG. 3. On the other hand, in the pouch 200a according
to the second exemplary embodiment, as shown in FIG. 5, the lower
end of the contents-accommodating section 210a is extended to the
lower end of the temperature controller 220 so that the
contents-accommodating section 210a and the temperature controller
220 can be coupled with each other in a lower region by ultrasonic
waves or thermal welding.
[0143] A communication hole 211b, 213b may be formed in the
contents-accommodating section 210a so that the front and back
temperature control spaces S2, S3 can communicate with each other.
Here, the edge of the communication hole 211b, 213b is sealed up to
prevent the contents accommodated in the contents-accommodating
space S1 from leaking out through the communication hole 211b,
213b.
Third Exemplary Embodiment
[0144] A pouch 200b according to the third exemplary embodiment may
as shown in FIGS. 6 and 7 include a contents-accommodating section
210, a temperature controller 220 and a sealing portion 240.
[0145] According to the third exemplary embodiment, the
contents-accommodating section 210 and the temperature controller
220 except the sealing portion 240 are the same as those of the
first exemplary embodiment.
[0146] According to the third exemplary embodiment, the sealing
portion 240 may include an adhesive tape 240 to seal up the upper
end of the liquid reactant entrance 222. Thus, it is possible to
prevent foreign materials (in particular, liquid) from being
introduced into the temperature control spaces S2, S3 while the
contents are put into the contents-accommodating section S1 and
sterilized after the upper end of the contents-accommodating
section S1 is sealed up.
[0147] Meanwhile, the adhesive tape 240 includes an extended
portion 241 extended so that one side there of can be gripped.
Thus, a user can easily put the liquid reactant into the pouch 200b
by pulling the extended portion 241 and removing the adhesive tape
240.
Fourth Exemplary Embodiment
[0148] A pouch 200c according to a fourth exemplary embodiment
includes a contents-accommodating section 210; a temperature
controller 220; a sealing portion 230 and a pouch stand 250 as
shown in FIG. 8.
[0149] The pouch 200c according to the fourth exemplary embodiment
allows the contents-accommodating section 210 to stand by itself
without any separate standing device as compared with the pouches
200, 200a, 200b according to the first to third exemplary
embodiments.
[0150] The pouch stand 250 is coupled to a lower side of the pouch
200c so that the pouch 200c can stand.
[0151] In more detail, one end of the pouch stand 250 is coupled to
the lower end portion of the second front film 221a, thereby
forming a front lower edge. Also, the other end of the pouch stand
250 is coupled to the lower end of the second back film 224a,
thereby forming a back lower edge spaced apart from the front lower
edge. Thus, the lower edges of the pouch 200c are broadened so that
the pouch 200c can stand by itself without any separate device.
[0152] Here, if it is desired to change the pouch 200a as shown in
FIG. 4 in a standable form, the pouch stand 250 may be interposed
between the lower end of the first front film 211a and the lower
end of the first back film 213a.
[0153] Meanwhile, the pouch stand 250 may include a transparent
window 253 through which the inside of the pouch 200c can be seen.
In the case of the standable pouch 200c according to the fourth
exemplary embodiment, a bottom formed by the pouch stand 250 may
have a transparent window 253 besides the plurality of transparent
windows 215, 216, 217 described in the first exemplary embodiment.
The transparent window 253 may be formed by making at least one
region of the pouch stand 250 with a transparent substance. As
necessary, the pouch stand 250 may be entirely made of a
transparent substance. Thus, a user can determine whether a product
is defective or not with his/her naked eyes through the transparent
window 253 formed on the bottom of the pouch 200c.
[0154] When the contents-accommodating section 210 is filled with
the contents, the lower portion of the contents-accommodating
section 210 may be expanded toward the pouch stand 25. In more
detail, the lower portion of the contents-accommodating section 210
is creased so that the contents-accommodating section 210 can
expand toward the pouch stand 25 when the contents-accommodating
section 210 is filled with the contents.
[0155] Also, the lower portion of the contents-accommodating
section 210 is arranged near to the inside of the pouch stand 25 so
that both the pouch stand 25 and the contents-accommodating section
210 can expand toward the bottom supporting the pouch 200 by the
weight of the contents accommodated in the contents-accommodating
section 210.
Fifth Exemplary Embodiment
[0156] A pouch 200d according to a fifth exemplary embodiment as
shown in FIG. 9 includes a contents-accommodating section 210b; a
temperature controller 220; a sealing portion 230 and a pouch stand
250.
[0157] According to the fifth exemplary embodiment, the
contents-accommodating section 210b may be formed by sealing up a
first front film 211b, an inner bottom film 218 and a first back
film 213b. In more detail, one end and the other end of the inner
bottom film 218 are respectively sealed and coupled to the lower
end of the first front film 211b and the lower end of the first
back film 213b, thereby forming the contents-accommodating section
210b. The inner bottom film 218 surely secures a lower space of the
contents-accommodating section 210b so that the
contents-accommodating space S1 can be filled with more
contents.
Sixth Exemplary Embodiment
[0158] FIG. 10 is a perspective view of a pouch according to the
sixth exemplary embodiment, FIG. 11 is a section view, taken along
line A2-A2 of FIG. 10, FIG. 12 is a section view showing that the
pouch shown in FIG. 11 is filled with the temperature controllable
object, and FIG. 13 is a section view showing that a sealing
portion is opened to put a liquid reactant into the temperature
control space of the pouch shown in FIG. 11.
[0159] As shown in FIGS. 10 to 13, a pouch 100 according to the
sixth exemplary embodiment includes an accommodating section 110, a
temperature controller 130 provided with a temperature control
agent 131, a sealing portion 140, a grip portion 150, a supporter
160, a sealing-bar attachment-preventing portion 170 and a cutting
portion 180.
[0160] The pouch 100 according to the sixth exemplary embodiment
does not include the temperature control agent 131 and the liquid
reactant W for the exothermic or endothermic reaction. That is, the
liquid reactant W is put into the pouch 100 from the outside in
order to control the temperature of the temperature controllable
object 10.
[0161] Here, the temperature controllable object 10 includes
various instant food such as the retort pouch. For example, the
contents may include food such as boiled rice, Bibimbap, soup, stew
or dry milk; a pad containing medicine for taking a hot massage or
a cold massage, or a mask pad containing beauty ingredients.
Besides, the contents may be varied as long as it has to be
instantly heated or cooled.
[0162] The accommodating section 110 includes a first accommodating
section film 112 and a second accommodating section film 114. An
accommodating space 116 for accommodating the temperature
controllable object 10 is formed between the first accommodating
section film 112 and the second accommodating section film 114.
Here, the first accommodating section film 112 and the second
accommodating section film 114 may be made of a heat-resistant
plastic film.
[0163] In more detail, the accommodating section 110 may be made of
the plastic film such as polyethylene (PE), polypropylene (PP), or
a polyethyelene terephthalate (PET). Of course, the first
accommodating section film 112 and the second accommodating section
film 114 constituting the accommodating section 110 may be made of
well-known synthetic resin films of various materials.
[0164] For example, the first accommodating section film 112 may
include a CPP film having a thickness of 60 .mu.m, an aluminum film
having a thickness of 9 .mu.m, or a combination film between a
nylon film having a thickness of 15 .mu.m and a CPP film having a
thickness of 60 .mu.m. Of course, this is nothing but illustrative.
The first accommodating section film 112 may include a combination
film of various materials, or as necessary include a film of a
single material. The second accommodating section film 114 may be
made of the same material as that of the first accommodating
section film 112.
[0165] The first accommodating section film 112 and the second
accommodating section film 114 form an envelope shape as the other
side and both sides connecting one side and the other side are
adhered and sealed so as to open one side. As the first
accommodating section film 112 and the second accommodating section
film 114 are adhered, the accommodating space 116 accommodating the
temperature controllable object 10 is formed. Trough an opening
side of the accommodating section 110, the temperature controllable
object 10 is filled in the accommodating space 116, and the opening
side is sealed up by the sealing-bar attachment-preventing portion
170 to be described later after the temperature controllable object
10 is completely filled.
[0166] The temperature controller 130 may be formed at one side
between both sides of the accommodating section 110. The
temperature control agent 131 is accommodated in between the
temperature controller 130 and the outer side of the accommodating
section 110, and exothermally or endothermally reacts with the
liquid reactant w to be inserted, thereby heating or cooling the
temperature controllable object 10.
[0167] The temperature controller 130 according to the sixth
exemplary embodiment includes the temperature control agent 131
arranged at least one side between front and back sides of the
accommodating section 110 and heating or cooling the temperature
controllable object (i.e., the contents); and a temperature control
space forming member 132 provided in a lower side of the
accommodating section 110 rather than an upper side thereof, having
the liquid reactant entrance 136 through which the liquid reactant
w is inserted, and forming a temperature control space 134 where
the exothermic or endothermic reaction occurs.
[0168] The temperature control agent 131 includes a reactant 131b
and a reactant accommodating section 131a. According to the sixth
exemplary embodiment, the temperature control agent 131 is arranged
at one side between both sides of the accommodating section 110.
The temperature control agent 131 may be arranged at a side facing
the first accommodating section film 112. The temperature control
agent 131 reacts with the liquid reactant w such as water inserted
from the outside.
[0169] The reactant 131b includes the heating element or the heat
absorption agent in accordance with whether to heat or cool the
temperature controllable object 10 accommodated in the
accommodating section 110. The reactant 131b may include at least
one as the heating element among calcium oxide (CaO), calcium
hydroxide (Ca(OH)2), magnesium chloride (MgCl2), iron (Fe) and
aluminum (Al). Here, the reactant 131b may be replaced or changed
by other substances as long as it can exothermally react with the
liquid reactant w.
[0170] On the other hand, the reactant 131b may include at least
one as the heat absorption agent among ammonium nitrate (NH4NO3),
sodium acetate (CH3COONa) and (urea). Of course, the reactant 131b
may be replaced or changed by other substances as long as it can
endothermally react with the liquid reactant w.
[0171] The reactant accommodating section 131a accommodates the
reactant 131b. The reactant accommodating section 131a includes a
body 131a1 and a partition 131a2. The reactant accommodating
section 131a is provided as an absorption fabric to quickly absorb
the liquid reactant w. As necessary, the reactant accommodating
section 131a may be made of not the absorption fabric but other
substances.
[0172] The body 131a1 is provided to accommodate the reactant 131b.
Here, the body 131a1 according to an exemplary embodiment is
partitioned into four accommodating regions by the partition 131a2.
Thus, the reactant 131b is accommodated in each of the plurality of
accommodating regions partitioned by the partition 131a2, thereby
preventing the reactant 131b from being leaning by its own weight.
Also, the reactant 131b is accommodated in each of the plurality of
accommodating regions, and thus the divided reactant 131b
individually contacts the liquid reactant w, thereby making a
temperature control reaction quickly.
[0173] The temperature control space forming member 132 together
with the first accommodating section film 112 forms the temperature
control space 134 to accommodate the temperature control agent 131.
The temperature control space 134 is a space where the exothermic
or endothermic reaction occurs when the liquid reactant w is
inserted, and has a margin space to accommodate the liquid reactant
w in addition to the temperature control agent 131.
[0174] Here, the temperature control space forming member 132 may
be made of a transparent synthetic resin film so that the liquid
reactant w and the temperature control agent 131 to be inserted can
be checked by naked eyes. Of course, the temperature control space
forming member 132 may be partially made of the transparent
synthetic resin film checkable by naked eyes. Of course,
checkability by naked eyes is optional, and thus an opaque film may
be used as necessary. The temperature controller 130 may be
provided smaller than the accommodating section 110 so that an
upper opening of the accommodating section 110 for inserting the
temperature controllable object 10 can be exposed. According to an
exemplary embodiment, the height of the temperature control space
forming member 132 may be eight tenth with respect to the height of
the accommodating section 110.
[0175] The temperature control space forming member 132 may have an
upper end lower than that of the contents-accommodating section
110.
[0176] The temperature control space forming member 132 may be made
of the plastic film. For example, the temperature control space
forming member 132 may be the plastic film where a PET film having
a thickness of 12 .mu.m and a CPP film having a thickness of 60
.mu.m are combined. Of course, this is nothing but illustrative.
Alternatively, the plastic film may be a combination film where
films of various well-known substances are combined or a single
material film.
[0177] Meanwhile, the temperature controller 130 adjacent to the
opening of the accommodating section 110 includes a liquid reactant
insertion portion 136 for opening and closing the temperature
control space 134 to insert the liquid reactant therethrough. The
liquid reactant insertion portion 136 is coupled to the
contents-accommodating section 110 by the sealing portion 140 to be
described later, and seals up the temperature control space
134.
[0178] The liquid reactant insertion portion 136 may be spaced part
from the sealing portion 140 or the first accommodating section
film 112 when force of not less than a predetermined magnitude is
applied for inserting the liquid reactant w in the temperature
control space 134. Thus, the upside of the temperature control
space 134 is opened so that the liquid reactant w can be inserted
in the temperature control space 134.
[0179] The sealing portion 140 seals up the accommodating section
110 and the temperature controller 130, specifically, the liquid
reactant insertion portion 136, thereby sealing up the temperature
control space 134. Here, the sealing portion 140 seals up the
accommodating section 110 and the liquid reactant insertion portion
136 with predetermined intensity of adhesion so that the
temperature control space 134 can be opened when force of not less
than a predetermined magnitude is applied for spacing the liquid
reactant insertion portion 136 apart from the accommodating section
110. That is, when the liquid reactant insertion portion 136 is
pulled by force of not less than a predetermined magnitude strong
enough to overcome the adhesion, the temperature control space 134
is opened. On the other hand, if force of not less than a
predetermined magnitude is not applied, the sealing is maintained
so that foreign materials including the liquid reactant cannot be
introduced into the temperature control space 134.
[0180] Here, the sealing portion 140 may have an adhesive strength
of not less than 200 gf/cm.sup.2 and not more than 5 kgf/cm.sup.2.
In experimental results, if the adhesive strength is less than 200
gf/cm.sup.2, the sealing may not be maintained when the temperature
controllable object 10 is filled and then heated to expand the
temperature control space 134. On the other hand, the adhesive
strength is more than 5 kgf/cm.sup.2, it is difficult for a regular
adult to open the temperature control space 134.
[0181] Preferably, the sealing portion 140 may have a adhesive
strength of 500 gf/cm.sup.2.about.3 kgf/cm.sup.2.
[0182] According to an exemplary embodiment, the sealing portion
140 is placed on the planar surface of the first accommodating
section film 112, and seals up between the liquid reactant
insertion portion 136 of the temperature controller 130 and the
first accommodating section film 112. Thus, the sealing portion 140
seals up between the first accommodating section film 112 and the
liquid reactant insertion portion 136, and prevents foreign
materials from being introduced into the temperature control space
134 while the temperature controllable object 10 is filled in the
accommodating space 116 of the accommodating section 110 and then
sterilized. Such sterilization is essential when a retort pouch is
produced by putting stew, soup, boiled rice and the like instant
foods into the pouch 100.
[0183] Meanwhile, the sealing portion 140 may be released from the
sealing with the liquid reactant insertion portion 136 when force
of not less than a certain magnitude is applied for inserting the
liquid reactant w into the temperature control space 134 as
temperature control is required for the temperature controllable
object 10. Then, the liquid reactant insertion portion 136 is
opened to open the temperature control space 134, so that the
liquid reactant w can be inserted in the temperature control space
134. Accordingly, the exothermic or endothermic reaction occurs
between the temperature control agent 131 and the liquid reactant
w.
[0184] Here, the sealing portion 140 may include at least one among
liquid adhesive for adhering the first accommodating section film
112 and the liquid reactant insertion portion 136, a solid adhesive
tape, and an easy peel film provided between the first
accommodating section film 112 and the liquid reactant insertion
portion 136.
[0185] Here, the solid adhesive tape may be a film type tape, one
or both sides of which the adhesive is applied to.
[0186] The easy peel film couples both films thereof with
predetermine thermal adhesion when heat of a predetermined
temperature range is applied. Here, the coupling force or adhesion
may be controlled by adjusting the temperature range of heat
applied to the easy peel film.
[0187] Here, the adhesive strength due to the sealing portion 140
between the liquid reactant entrance 136 and the accommodating
section 110 is weaker than contact strength between the temperature
control space forming member 132 and the accommodating section 110
besides the liquid reactant entrance 136.
[0188] In more detail, the liquid reactant entrance 136 is expected
to be opened so as to insert the liquid reactant in the temperature
control space 134, and therefore the adhesive strength of the
partial sealing portion C6 between the liquid reactant entrance 136
and the accommodating section 110 may be weaker than the adhesive
strength of the partial sealing portion C7 in a lateral edge
between the temperature control space forming member 132 and the
accommodating section 110. This may be achieved by changing the
temperature range of the sealing bar used when sealing the partial
sealing portions C7, C6. Such temperature range will be described
later.
[0189] Meanwhile, the grip portion 150 is provided to grip the
liquid reactant insertion portion 136 of the temperature controller
130. The grip portion 150 is extended from the liquid reactant
insertion portion 136 and formed integrally with the liquid
reactant insertion portion 136.
[0190] The grip portion 150 may protrude from the liquid reactant
insertion portion 136. The grip portion 150 may be provided in a
center region of the liquid reactant insertion portion 136. The
grip portion 150 protrudes from the center region of the liquid
reactant insertion portion 136 and is gripped by a user. In
particular, the grip portion 150 is gripped by a user and transfers
a user's force to the liquid reactant insertion portion 136 so that
the liquid reactant insertion portion 136 can be released from the
accommodating section 110. To make a user easily grip the grip
portion 150 and efficiently transfer his/her force, the grip
portion 150 may protrude from the center portion of the liquid
reactant insertion portion 136.
[0191] Of course, the grip portion 150 may be provided at both
sides of the liquid reactant insertion portion 136.
[0192] The supporter 160 is provided in at least one of the outer
side of the accommodating section 110 forming the temperature
control space 134 and the inner side of the temperature controller
130. The supporter 160 supports the temperature control agent 131
in the temperature control space 134 and prevents the temperature
control agent 131 from moving. That is, the supporter 160 prevents
the temperature control agent 131 from moving during a distribution
process of the pouch 100. The supporter 160 is not essential for
the pouch 100, and may be omitted as necessary.
[0193] According to an exemplary embodiment, the supporter 160 is
placed on an inner side of the temperature control space forming
member 132 and supports the temperature control agent 131. Of
course, the supporter 160 may be placed on an outer side of the
first accommodating section film 112 and support the temperature
control agent 131. The supporter 160 may be made of various
adhesive materials such as the adhesive tape in order to support
the temperature control agent 131 against the temperature control
space forming member 132.
[0194] Meanwhile, when the sealing-bar attachment-preventing
portion 170 seals up the upper ends of the first accommodating pack
film 112 and the second accommodating pack film 114 by the sealing
bar 131a2 having a predetermined sealing temperature in order to
seal up the upper side of the accommodating section 110, the first
accommodating pack film 112 is attached to and not separated from
the sealing bar.
[0195] In more detail, the first accommodating pack film 112 is as
described above made of a single CPP film or a combination film
where the CPP film is exposed. The CPP film may be attached to and
not well separated from the sealing bar, and to prevent this, the
sealing-bar attachment-preventing portion 170 may be provided in
the accommodating section 110 contacting the sealing bar.
[0196] The PET substance may be used as a material not well
attached to the sealing bar. The sealing-bar attachment-preventing
portion 170 may include a film of which a part exposed frontward is
combined with the PET film, or a single PET film.
[0197] For example, the sealing-bar attachment-preventing portion
170 may be the same plastic film as the temperature control space
forming member 132, where the PET film having a thickness of 12
.mu.m and the CPP film having a thickness of 60 .mu.m are combined.
Here, the PET film has to be arranged to be exposed frontward so
that the PET film can contact the sealing bar.
[0198] Here, it is just illustrative that the PET is used as a
material for the sealing-bar attachment-preventing portion 170. The
PET may be replaced by the plastic films of various well known
materials as long as it cannot well attached to the sealing
bar.
[0199] The cutting portion 180 is provided between the liquid
reactant insertion portion 136 and the sealing-bar
attachment-preventing portion 170.
[0200] The cutting portion 180 may include a notch cut in a
transverse direction at one or both sides of the accommodating
section 110 so that the accommodating section 110 can be torn when
transverse force of not less than a certain magnitude is
applied.
[0201] The cutting portion may be so thin that the portion cut by
the notch can be easily torn.
[0202] As shown in FIG. 11, since the first accommodating section
film 112 and the second accommodating section film 114 exist in the
cutting portion AA1 formed with the notch, it is thinner than three
layered films of the sealing-bar attachment-preventing member 170,
and the first and second accommodating section films 112, 114
placed above the accommodating section 110.
[0203] Also, total four layered films of the temperature control
space forming member 132, the sealing portion 140, the first
accommodating section film 112 and the second accommodating section
film 114 exist below the cutting portion AA1, and therefore the
cutting portion AA1 having total two layered films is relatively
thin. Thus, the cutting portion AA1 can be more easily torn.
[0204] Meanwhile, the supporter 160, the sealing-bar
attachment-preventing portion 170 and the cutting portion 180
described above are not essential, and all or a part of them 160,
170, 180 may be omitted as necessary.
[0205] Meanwhile, the foregoing illustrates that the lateral edges
C7 of the first accommodating section film 112 and the second
accommodating section film 114 of the accommodating section 110 are
directly sealed up. As necessary, the cross section of the lateral
edges may be creased like "" so that a user can more easily grip
the lateral side of the pouch 100. This may be achieved by
interposing a separate film between the lateral edges of the first
accommodating section film 112 and the second accommodating section
film 114 and thus broadening both edges.
Seventh Exemplary Embodiment
[0206] FIG. 14 is a section view of a pouch according to a seventh
exemplary embodiment, and FIG. 15 is a section view showing that a
temperature controllable object is filled in the pouch shown in
FIG. 14
[0207] As shown in FIG. 14 and FIG. 15, a pouch 300 according to
the seventh exemplary embodiment includes a temperature controller
330 provided with a plurality of temperature control agents 131
respectively arranged in the first accommodating section film 112
and the second accommodating section film 114 of the accommodating
section 110. Here, among the elements of the pouch 300 according to
the seventh exemplary embodiment, the accommodating section 110,
the temperature control agent 131, the supporter 160, the
sealing-bar attachment-preventing portion 170 and the cutting
portion 180 are the same as those of the sixth exemplary
embodiment, and thus repetitive descriptions thereof will be
avoided.
[0208] The temperature controller 330 includes a first temperature
control space forming member 331, a second temperature control
space forming member 332, a first liquid reactant insertion portion
337 and a second liquid reactant insertion portion 338. The first
temperature control space forming member 331 and the second
temperature control space forming member 332 respectively
accommodate the first accommodating section film 112 and the second
accommodating section film 114. Between the first temperature
control space forming member 331 and the second temperature control
space forming member 332 and between the first accommodating
section film 112 and the second accommodating section film 114 are
formed the first temperature control space 334 and the second
temperature control space 335, respectively. Here, each of the
first temperature control space 334 and the second temperature
control space 335 accommodate the temperature control agent
131.
[0209] Further, the upper regions of the first temperature control
space forming member 331 and the second temperature control space
forming member 332 are provided with the first liquid reactant
insertion portion 337 and the second liquid reactant insertion
portion 338 to open and close the temperature control spaces 334,
335, respectively.
[0210] The sealing portion 340 is provided to allow the first
liquid reactant insertion portion 337 and the second liquid
reactant insertion portion 338 to seal up the first temperature
control space 334 and the second temperature control space 335,
respectively. The sealing portion 340 includes the first sealing
portion 342 for sealing up between the first accommodating section
film 112 and the first liquid reactant insertion portion 337, and a
second sealing portion 344 for sealing up between the second
accommodating section film 114 and the second liquid reactant
insertion portion 338. Here, the first sealing portion 342 and the
second sealing portion 344 may include the liquid adhesive or the
solid adhesive tape or the easy peel film like the sealing portion
140 according to the sixth exemplary embodiment.
[0211] The grip portion 350 includes a first grip portion 352 and a
second grip portion 354 to be gripped so that the first liquid
reactant insertion portion 337 and the second liquid reactant
insertion portion 338 can open the first temperature control space
334 and the second temperature control space 335, respectively. The
first grip portion 352 may be placed in the center region of the
first liquid reactant insertion portion 337, and the second grip
portion 354 may be placed in the center region the second liquid
reactant insertion portion 338. The first grip portion 352 and the
second grip portion 354 have the same shape as that of the grip
portion 150 according to the sixth exemplary embodiment. Of course,
the first grip portion 352 and the second grip portion 354 may have
a different shape from the grip portion 150 according to the sixth
exemplary embodiment.
[0212] As described above, the pouch 300 according to the seventh
exemplary embodiment accommodates two temperature control agents
131 in two temperature control spaces 334, 335 on the contrary to
the sixth exemplary embodiment, and thus can more quickly control
the temperature of the temperature controllable object 10 than the
pouch 100 according to the sixth exemplary embodiment.
Eighth Exemplary Embodiment
[0213] FIG. 16 is a perspective view of a pouch according to an
eighth exemplary embodiment.
[0214] A pouch 500 according to the eighth exemplary embodiment as
shown in FIG. 16 includes a grip portion 550 different from those
of the pouches 100, 300 according to the first and seventh
exemplary embodiments.
[0215] The grip portion 550 according to the eighth exemplary
embodiment includes a grip body 552 and a cutting line 554. The
grip body 552 is provided in a transverse direction of the drawing
at the upper opening of the temperature control space 134, that is,
a region to be sealed up by the sealing portion 140. The cutting
line 554 is provided to open the temperature control space 134 when
force of not less than a certain magnitude is applied to the grip
body 552. That is, the cutting line 554 is removed from the
temperature controller 130 when transverse force is applied to the
grip body 552, and opens the temperature control space 134.
[0216] Here, in the pouch according to the eighth exemplary
embodiment, foreign materials may enter the temperature control
space 134 through the cutting line 554 during a sterilization
process. Therefore, the pouch according to the eighth exemplary
embodiment can be used when there is no need of the sterilization
process after the temperature controllable object (i.e., the
contents) is filled in the accommodating section 110 of the pouch
500. For example, if the temperature controllable object (i.e., the
contents) is solid dried food or a liquid or solid beauty product,
the sterilization process may be not needed.
[0217] Here, a partial region of the grip body 552 may protrude
from the accommodating section 110 so that a user can easily grip
it.
[0218] The grip portion 550 according to the eighth exemplary
embodiment is provided with the cutting line 554 at the opening
side of the temperature controller 130, thereby improving the
sealing of the temperature control space 134 and convenience when
opening the temperature control space 134.
Ninth Exemplary Embodiment
[0219] Lastly, FIG. 17 is a section view of a pouch according to a
ninth exemplary embodiment.
[0220] The pouch 700 according to the ninth exemplary embodiment
may be applied to the pouches 100, 300, 500 according to the first
to eighth exemplary embodiments. The pouch 700 according to the
ninth exemplary embodiment includes a pouch stand 790 so as to make
the accommodating section 110 stand.
[0221] The pouch stand 790 according to an exemplary embodiment is
provided between the first accommodating section film 112 and the
second accommodating section film 114 of the accommodating section
110. Here, the pouch stand 700 may be made of a film thickener than
the first accommodating section film 112 and the second
accommodating section film 114 constituting the accommodating
section 110. Of course, the pouch stand 790 may be placed between
the accommodating section 110 and the temperature controller 130,
but may be placed between the first accommodating section film 112
and the second accommodating section film 114 constituting the
accommodating section 110 according to an exemplary embodiment in
order to stably keep a standing state the pouch 700.
[0222] Thus, the pouch stand 790 is provided to make the pouch 700
stand, so that the temperature control for the temperature
controllable object inside the pouch 700 can be stably
performed.
Tenth Exemplary Embodiment
[0223] A pouch 100a according to a tenth exemplary embodiment as
shown in FIG. 18 to FIG. 20 includes an accommodating section 110;
a temperature controller 130 including a temperature control agent
131, a liquid reactant entrance 136 and a temperature control space
forming member 132; a sealing portion 140, a cutting portion 180
and a pouch stand 790.
[0224] The pouch 100a according to the tenth exemplary embodiment
does not include the supporter 160 and the sealing-bar
attachment-preventing portion 170 as compared with that 100 of the
sixth exemplary embodiment.
[0225] As shown in FIG. 19, in the state that the upper end
portions of the first and second accommodating section films 112,
114 are not sealed up and the upper portion of the accommodating
section 110 is being opened, the temperature controllable object 10
is inserted in the accommodating section 110 along an inserting
direction D.
[0226] To heat or cool the temperature controllable object 10
accommodated in the accommodating section 110, a user first grips
the grip portion 150 as shown in FIG. 21, and pulls the liquid
reactant entrance 136 in a direction F, thereby spacing it apart
from the accommodating section 110. At this time, if force of not
less than a predetermined magnitude is applied for spacing the
liquid reactant entrance 136 apart from the accommodating section
110, the liquid reactant entrance 136 is opened. As described
above, the thermal adhesive strength in the sealing region C6 due
to the sealing portion 150 is weaker than the thermal adhesive
strength of the edge portion C7 of the accommodating section 110,
and therefore the liquid reactant entrance 136 can be more easily
opened than other portions.
[0227] In the state that the temperature control space 134 is being
opened, the liquid reactant is inserted in a direction H.
Accordingly, the exothermic or endothermic reaction occurs between
the liquid reactant and the temperature control agent 131 within
the temperature control space 134, and thus the temperature
controllable object 10 accommodated in the accommodating space 116
is heated or cooled.
[0228] After a lapse of predetermined time, a user uses the grip
portion 180 to cut open the upper end of the accommodating section
110. Thus, a user takes in, takes out or uses the heated or cold
temperature controllable object 10 through the accommodating
section 110 having the opened upper portion.
Eleventh Exemplary Embodiment
[0229] A pouch 300a according to an eleventh exemplary embodiment
as shown in FIG. 22 includes an accommodating section 110; a
temperature controller 330 provided with a plurality of temperature
control agents 131 respectively arranged in a first accommodating
section film 112 and the second accommodating section film 114; and
a sealing portion 140a for sealing up a plurality of temperature
control spaces 334, 335 accommodating a plurality of temperature
control agents 131.
[0230] As compared with the pouch 300 according to the seventh
exemplary embodiment shown in FIG. 14, the pouch 300a according to
the eleventh exemplary embodiment does not include the supporter
(160 in FIG. 14) and the sealing-bar attachment-preventing portion
(170 in FIG. 14) of the eleventh exemplary embodiment. Also, the
pouch 300a according to the eleventh exemplary embodiment is
different in including a pouch stand 790 and standing from that 300
of the seventh exemplary embodiment.
[0231] The sealing portion 140 includes a first sealing portion 141
for sealing up the first temperature control space 334 and a second
sealing portion 143 for sealing up the second temperature control
space 335.
[0232] The first and second sealing portions 141, 143 may be made
of the same substance as that of the foregoing sealing portion
140.
[0233] The first and second sealing portions 141, 143 seal up
between the first temperature control space forming member 331 and
the first accommodating section film 112 and between the second
temperature control space forming member 332 and the second
accommodating section film 114 so that the first and second liquid
reactant entrances 337, 338 can be opened when force of not less
than a certain magnitude is applied for spacing the first and
second liquid reactant entrances 337, 338 and the
contents-accommodating section 110 apart from each other.
[0234] Here, a user employs the plurality of first grip portion 352
and second grip portion 354 as shown in FIG. 22 to respectively
open the first and second temperature control spaces 334, 335, and
inserts the liquid reactant therein, thereby heating or cooling the
temperature controllable object within the accommodating space
116.
Twelfth Exemplary Embodiment
[0235] A pouch 300b according to a twelfth exemplary embodiment as
shown in FIG. 23 includes an accommodating section 110a including a
first accommodating section film 112, a second accommodating
section film 114 and a spacing film 115 spaced apart from the pouch
stand 790; a temperature controller 230 including the plurality of
temperature control agents 131 respectively arranged in the first
accommodating section film 112 and the second accommodating section
film 114; a sealing portion 140 for sealing up one among the
plurality of temperature control spaces 234, 235 accommodating the
plurality of temperature control agents 131; a grip portion 150;
and a cutting portion (180 in FIG. 1).
[0236] The pouch 300b according to the twelfth exemplary embodiment
does not include the supporter (600 in FIG. 14) as compared with
the pouch 300 according to the seventh exemplary embodiment shown
in FIG. 14. Also, the pouch 300b according to the twelfth exemplary
embodiment is different from that 300 of the seventh exemplary
embodiment in that it includes the pouch stand 790 and is capable
of standing, that the lower portion of the accommodating section
110a is spaced apart from the pouch stand 790, that the sealing
portion 140 is arranged at one side among the plurality of
temperature control spaces 234, 235, that the sealing-bar
attachment-preventing portion 170 is arranged at one side between
the front and back sides of the pouch 300b, and that the plurality
of temperature control spaces 234, 235 communicate with each
other.
[0237] The first and second accommodating section films 112, 114
and the spacing film 115 of the accommodating section 110a may be
provided as a single material film. As necessary, they may be
manufactured as individually separately cut-open films and then
sealed up.
[0238] The temperature controller 230 includes first and second
temperature control space forming members 231, 232 sealed with the
first and second accommodating section films 112, 114 to form the
first and second temperature control spaces 234, 234; and the
plurality of temperature control agents 131 respectively
accommodated in the first and second temperature control spaces
231, 232.
[0239] The upper end of the first temperature control space forming
member 231 is lower than the upper end of the
contents-accommodating section 110.
[0240] The first temperature control space forming member 231
includes a liquid reactant entrance 237 through which the liquid
reactant for exothermically or endothermically reacting with the
temperature control agent 131 can be inserted in the first
temperature control space 231.
[0241] The sealing portion 140 is provided between the liquid
reactant entrance 237 of the first temperature control space
forming member 231 and the first accommodating section film
112.
[0242] The liquid reactant entrance 237, the sealing portion 140
and the first accommodating section film 112 are thermally adhered
by heat and thus sealed up.
[0243] After the temperature controllable object (i.e., the
contents) is filled in the state that the accommodating section
110a is being opened, the sealing bar heated up to a predetermined
temperature applies heat along the upper end edges of the
accommodating section 110 toward the sealing-bar
attachment-preventing portion 170, thereby sealing up the upper end
of the accommodating section 110. Accordingly, it is possible to
prevent the accommodating section 110 from being attached to the
sealing bar.
[0244] The sealing-bar attachment-preventing portion 170, the first
temperature control space forming member 231 and the second
temperature control space forming member 232 may be all made of the
same material. For example, the sealing-bar attachment-preventing
portion 170, the first temperature control space forming member 231
and the second temperature control space forming member 232 may be
made of the plastic film where the PET film having a thickness of
12 .mu.m and the CPP film having a thickness of 60 .mu.m are
combined.
[0245] To heat or cool the temperature controllable object, a user
grips the grip portion 150 and applies force to the liquid reactant
entrance 237, thereby opening the first temperature control space
234. Further, the liquid reactant is inserted in the opened first
temperature control space 234. The liquid reactant put into the
first temperature control space 234 is introduced into a second
temperature control space 235 through a communication space J
between the accommodating section 110 and the pouch stand 790.
Thus, the exothermic or endothermic reaction can occur between the
liquid reactant and the temperature control agent 131 within even
the second temperature control space 235.
[0246] In the case of the pouch 300b according to the twelfth
exemplary embodiment, even though a user opens not both the
temperature control spaces 234, 235 but one of them to insert the
liquid reactant, the inserted liquid reactant can be transferred to
the unopened space. Accordingly, it is convenient for a user.
Thirteenth Exemplary Embodiment
[0247] A pouch 100b according to a thirteenth exemplary embodiment
as shown in FIG. 24 includes the accommodating section 110, the
temperature controller 130, the sealing portion 240, the grip
portion 150, the sealing-bar attachment-preventing portion 170 and
the cutting portion (refer to 180 in FIG. 1).
[0248] As compared with the pouch 100 according to the sixth
exemplary embodiment, the pouch 100b according to the thirteenth
exemplary embodiment does not include the supporter 160 and has the
sealing portion 240 different in shape from the sealing portion 140
according to the sixth exemplary embodiment. Also, as compared with
the pouch 100 according to the sixth exemplary embodiment, the
pouch 100b according to the thirteenth exemplary embodiment further
includes the pouch stand 790 and thus is standable.
[0249] The sealing portion 240 may be provided to cover the entire
of the first accommodating section film 112 of the accommodating
section 110.
[0250] While the sealing portion 140 of the pouch 100 according to
the sixth exemplary embodiment has a predetermined width as shown
in FIG. 2, the pouch 100b according to the thirteenth exemplary
embodiment includes the sealing portion 240 provided to cover the
entire of the accommodating section 110.
[0251] Here, the sealing portion 240 may be provided as at least
one between the liquid or solid adhesive tape for adhering the
first accommodating section film 112 and the liquid reactant
insertion portion 136, and the easy peel film provided between the
first accommodating section film 112 and the liquid reactant
insertion portion 136.
[0252] Here, the solid adhesive tape may include a film type tape,
one-side or double-sides of which the adhesive is applied.
[0253] The easy peel film couples both films thereof with
predetermined thermal adhesive strength when heat of a
predetermined temperature range is applied thereto. Here, the
coupling force or adhesive force can be controlled by adjusting a
sealing temperature of sealing up the easy peel film.
[0254] According to the thirteenth exemplary embodiment, the
sealing portion 240 is provided to cover the entire of the first
accommodating section film 112, and therefore there is no need of
any separate position adjusting device for interposing the sealing
portion 240 between the liquid reactant entrance 136 and the first
accommodating section film 112.
Fourteenth Exemplary Embodiment
[0255] A pouch 300c according to a fourteenth exemplary embodiment
as shown in FIG. 25 includes the accommodating section 110; the
temperature controller 330; the sealing-bar attachment-preventing
portion 170; the cutting portion (refer to 180 in FIG. 1); the
sealing portion 240a and the grip portion 350.
[0256] As compared with the pouch according to the seventh
exemplary embodiment shown in FIG. 14, the pouch 300c according to
a fourteenth exemplary embodiment further includes the pouch stand
790 and is standable. Also, the sealing portion 240a according to
the fourteenth exemplary embodiment has the sealing portion 340
different in shape from that of the seventh exemplary embodiment
shown in FIG. 14.
[0257] The sealing portion 240a includes a first sealing portion
241 for covering the outer side, i.e., the front of the first
accommodating section film 112; and a second sealing portion 243
for covering the outer side, i.e., the back of the second
accommodating section film 114.
Fifteenth Exemplary Embodiment
[0258] A pouch 300c according to the fifteenth exemplary embodiment
as shown in FIG. 26A and FIG. 26B includes a accommodating section
110b capable of accommodating the temperature controllable object;
a temperature controller 430; a sealing portion 245; a sealing-bar
attachment-preventing portion 170; a cutting portion (refer to 180
in FIG. 1); and the grip portion 150.
[0259] The accommodating section 110b includes a first
accommodating section film 115 and a second accommodating section
film 117 to form the accommodating space 116 for accommodating the
temperature controllable object.
[0260] The first and second accommodating section films 115, 117
may be made of the same material as those 112, 114 of the sixth
exemplary embodiment.
[0261] The first and second accommodating section films 115, 117
include communication holes 115a, 117a for communicating the first
temperature control space 434 and the second temperature control
space 436 of the temperature controller 430 with each other
[0262] The temperature controller 430 includes the plurality of
temperature control agents 131 respectively arranged at both sides
of the accommodating section 110b to heat or cool the temperature
controllable object; a liquid reactant entrance 437 through which
the liquid reactant exothermically or endothermically reacting with
the temperature control agent 131 is insertable; and first and
second temperature control space forming members 431, 432 forming
the first and second temperature control spaces 434, 436 to
accommodate the plurality of temperature control agents 131,
respectively.
[0263] The sealing-bar attachment-preventing portion 170 is as
described above to prevent the accommodating section 110b from
being attached to the sealing bar when the upper end of the
accommodating section 110b is thermally adhered by the sealing bar
heated up to a predetermined temperature.
[0264] The sealing-bar attachment-preventing portion 170 may be as
described above made of the same material as that of the first
temperature control space forming member 431.
[0265] The sealing portion 245 may be provided to cover the outer
side, i.e., the front side of the first accommodating section film
115, like the sealing portion 240 of the thirteenth exemplary
embodiment.
[0266] The sealing portion 245 may also include a sealing portion
communication hole 245a formed at a position corresponding to the
communication holes 115a, 117a in the accommodating section 110a so
that the first temperature control space 434 and the second
temperature control space 436 can communicate with each other.
[0267] Thus, when the grip portion 150 is gripped to space the
liquid reactant entrance 437 apart from the accommodating section
110b and the liquid reactant is put into the first temperature
control space 434, the inserted liquid reactant can be introduced
into the second temperature control space 436 via the communication
holes 245a, 115a, 117a.
Sixteenth Exemplary Embodiment
[0268] A pouch 100c according to a sixteenth exemplary embodiment
as shown in FIG. 27A and FIG. 27B includes the accommodating
section 110 accommodating the temperature controllable object; the
temperature controller 130; the sealing portion 140; the grip
portion 150; the pouch stand 790 and a spout cap 170.
[0269] The pouch 100c according to the sixteenth exemplary
embodiment does not includes the cutting portion 180, the supporter
160 and the sealing-bar attachment-preventing portion 170 as
compared with the pouch according to the sixth exemplary
embodiment.
[0270] The pouch 100c according to the sixteenth exemplary
embodiment includes the spout cap 170 instead of the cutting
portion (refer to 180 in FIG. 1). If there is the cutting portion
(refer to 180 in FIG. 1) like the sixth exemplary embodiment, a
user cuts the cutting portion (refer to 180 in FIG. 1) and opens
the accommodating section 110, thereby taking in or using the
temperature controllable object 10a filled therein. On the other
hand, in the eleventh exemplary embodiment, a user opens the spout
cap 170 instead of cutting the cutting portion (refer to 180 in
FIG. 1) and then takes in the temperature controllable object
10a.
[0271] Here, the spout cap 170 may be replaced by a straw hole (not
shown) for receiving a straw and a soft tape attached to the hole.
In this case, a user puts the straw through the tape and takes in
the temperature controllable object 10a in the accommodating
section 110 through the hole.
[0272] The temperature controllable object 10a may include coffee,
soupe or the like beverage, or food.
[0273] Meanwhile, a method of manufacturing the pouch 100a
according to the fourteenth exemplary embodiment will be described
below with reference to FIG. 25 and FIG. 28A to FIG. 28C.
[0274] First, the first temperature control space forming member
331, the first sealing portion 241 and the first accommodating
section film 112 are combined to form the front side, i.e., the
outer skin. Here, the sealing-bar attachment-preventing portion 170
may also be placed on an upper side of the first sealing portion
241.
[0275] If the first temperature control space forming member 331
and the sealing-bar attachment-preventing portion 170 are made of
the same PET film, the PET films are cut and arranged at
predetermined positions before combination, so that the first
temperature control space forming member 331 and the sealing-bar
attachment-preventing portion 170 can be arranged.
[0276] A back outer skin opposite to the front outer skin is formed
with the pouch stand 790 therebetween. The back outer skin is
symmetrical to the front outer skin with the pouch stand 790
therebetween, and the second accommodating section film 114, the
second sealing portion 243 and the second temperature control space
forming member 332 are arranged in sequence from the upside.
[0277] Here, the temperature control agent 131 may be inserted
between the first sealing portion 241 and the first temperature
control space forming member 331 and between the second sealing
portion 243 and the second temperature control space forming member
332.
[0278] Meanwhile, the first and second temperature control space
forming members 331, 332, the temperature control agent 131 and the
sealing-bar attachment-preventing portion 170 may be wored by the
following process. That is, in more detail, the pouch stand 790,
the first and second accommodating section films 112, 114 and the
first and second sealing portions 241, 243 are first sealed in the
form of an envelope except their upper regions, and then the first
and second temperature control space forming members 331, 332 and
the sealing-bar attachment-preventing portion 170 are arranged on
the outer side of the envelop and then secondarily sealed up.
[0279] In the state of being combined as shown in FIG. 28A, the
edges of the other regions D2, D3 and D4 are sealed up except the
edge D1 corresponding to an upper opening of the
contents-accommodating space as shown in FIG. 28B. At this time,
the sealing may be achieved by thermal adhesion using the sealing
bar heated within a predetermined second temperature range. Thus,
the first and second accommodating section films 112, 114 form the
contents-accommodating space 116.
[0280] At this time, the predetermined second temperature range may
be 230.degree. C. or higher and 300.degree. C. or lower.
[0281] Next, the upper end region L of the first temperature
control space forming member 331 is thermally adhered to the first
sealing portion 241 and the first accommodating section film 112 by
the sealing bar heated within a predetermined first temperature
range. In more detail, the region to be sealed by the sealing bar
is a predetermined section S5 from a position spaced apart by a
predetermined width K1 from the upper end 331a of the first
temperature control space forming member 331 toward the temperature
control agent 331.
[0282] Here, the sealing of the sealing bar is not performed up to
a section spaced part by a predetermined width w from the upper end
331a of the first temperature control space forming member 331.
This region corresponds to the foregoing grip portion 150. The
center region upper end portion 331b of the temperature control
space forming member 331 is provided to protrude so that the grip
portion (see 150 in FIG. 1) can be formed in the form of the
protruded center portion.
[0283] Here, the first temperature range may be 150.degree. C. or
higher and 220.degree. C. or lower.
[0284] Since the first temperature range is lower than the second
temperature range, the sealing region J sealed up by the sealing
bar of the first temperature control space forming member 331
within the first temperature range has a thermal adhesive strength
sealing weaker than those of the edge regions (refer to D1, D2, D3,
D4 in FIG. 28B) sealed up by the sealing bar of the second
temperature range.
[0285] The sealing region J of the first temperature control space
forming member 331 corresponds to the foregoing liquid reactant
entrance 337. Accordingly, a user can easily open the liquid
reactant entrance 337 having a relatively weak thermal adhesive
strength.
[0286] After sealing up the sealing region J of the first
temperature control space forming member 331, the edge region D1 is
not being sealed but opened so that the temperature controllable
object can be inserted through such an opened opening.
[0287] Next, after the temperature controllable object is
completely inserted, the opened edge region D1 is thermally adhered
by the sealing bar heated within the second temperature range.
[0288] At this time, the predetermined second temperature range may
be 230.degree. C. or higher and 300.degree. C. or lower.
[0289] Meanwhile, the method of thermally adhering the second
temperature control space forming member 332 to the second
accommodating section film 114 and the second sealing portion 243
is the same as that for the first temperature control space forming
member 332, and the repetitive descriptions thereof will be
avoided.
[0290] Meanwhile, in the foregoing, the temperature control agent
131 is inserted between the first temperature control space forming
member 331 and the first sealing portion 241 and the edges D2, D3,
D4 are sealed up, and then the temperature controllable object is
filled in the accommodating space between the first and second
accommodating section films 112, 114.
[0291] However, in the case where the edges D2, D3, D4 of the first
and second accommodating section films 112, 114 first undergo the
sealing work, and then the first and second sealing portions 241,
243 and the first and second temperature control space forming
members 331, 332 undergo the following sealing process, the
contents-accommodating space is already formed, and therefore the
accommodating space is first filled with the temperature
controllable object and then filled with the temperature control
agent 131. Accordingly, the sealing work for the edges D2, D3, D4
may be performed once again. That is, the contents filling and
sealing process and the temperature control agent filling and
sealing process may be exchanged in order.
[0292] Here, if the temperature controllable object (i.e., the
contents) is coffee, soup or the like liquid food needed to be
sterilized, the contents filling and sealing processes may be
previously performed to the temperature control agent filling and
sealing process so as to make the contents filling process more
safety.
[0293] The sealing of the upper end edge D1 of the pouch may be
performed after the temperature controllable object (i.e., the
contents) is filled. As necessary, the upper end edge D1 may not be
sealed if the temperature controllable object (i.e., the contents)
is hardly affected by an external environment or if there is no
need of sealing the contents-accommodating space because its
expiration date is short.
[0294] Meanwhile, a method of manufacturing the pouch will be
described below with reference to FIG. 18 to FIG. 21 and FIG.
29.
[0295] First, the contents-accommodating section 110 capable of
accommodating the contents therein, the temperature control space
forming member 132 arranged in at least one side between the front
and back sides of the contents-accommodating section 110 and having
the upper end lower than that of the contents-accommodating
section, and at least one sealing portion 140 inserted between the
temperature control space forming member and the
contents-accommodating section are combined (S10).
[0296] Then, the upper end region of the temperature control space
forming member 132 with the sealing portion 140 is thermally
adhered to the contents-accommodating section 110 by the sealing
bar heated at the first temperature (S20). Here, the upper end
region, which corresponds to the liquid reactant entrance 136 of
the temperature control space forming member 132, seals up the
liquid reactant entrance 136.
[0297] Here, the first temperature may be 150.degree. C. or higher
and 220.degree. C. or lower. If the first temperature for heating
the sealing bar to thermally adhere the upper end region is lower
than 150.degree. C., the thermal adhesive strength of the liquid
reactant entrance 136 is so weak that the sealing of the
temperature control space 134 is deteriorated between the
temperature control space forming member 131 and the
contents-accommodating section 110, thereby allowing foreign
materials (e.g., moisture or the like) to be introduced.
[0298] On the other hand, if the first temperature is higher than
220.degree. C., the thermal adhesive strength of the liquid
reactant entrance 136 is so strong that it is difficult for a user
to open the temperature control space 134.
[0299] Next, the temperature control agent 131 is inserted in the
temperature control space forming member 131 and the
contents-accommodating section 140 (S30).
[0300] Next, the left and right sides and the lower sides of the
temperature control space forming member 132 filled with the
temperature control agent 131 are thermally adhered to the
contents-accommodating section 110 by the sealing bar heated up to
the second temperature (S40).
[0301] Here, the second temperature may be 230.degree. C. or higher
and 300.degree. C. or lower.
[0302] Here, the first temperature is lower than the second
temperature. As described above, this is to make a user easily open
the temperature control space 134 while keeping its sealing as the
thermal adhesive strength of the liquid reactant entrance 136
expected to be open is weaker than the other portions (i.e., the
left, right and lower edges).
[0303] Meanwhile, the combination of S10 includes primarily sealing
the left, right and lower edges of the contents-accommodating
section 110 and the sealing portion 140 so that the upper end of
the contents-accommodating section 110 can be open, by combining
the contents-accommodating section 110 and the sealing portion 140
(S11); and combining the temperature control space forming member
132 to the front side of the primarily sealed sealing portion 140
(S12). Thus, the accommodating space 116 is formed to accommodate
the temperature controllable object 10 in the state that the upper
end of the contents-accommodating section 110 is opened.
[0304] Here, in the primarily sealing (S11), only the
contents-accommodating section 110 may be combined and sealed
without the sealing portion 140. In this case, the sealing portion
140 together with the temperature control space forming member 132
may be sequentially combined to the contents-accommodating section
110 in the combination (S12).
[0305] Meanwhile, the operation of putting the temperature
controllable object 10 in the accommodating space 116 formed by the
primarily sealing may be performed between the primarily sealing
(S11) and the combination of the temperature control space forming
member 132 (S12).
[0306] As necessary, the operation of putting the temperature
controllable object 10 may be performed after the operation S40 of
thermally adhering the left, right and lower end regions of the
temperature control space forming member 132.
Seventeenth Exemplary Embodiment
[0307] As shown in FIG. 30 to FIG. 32, a pouch 2100 according to
the seventeenth exemplary embodiment includes a temperature
controller 2130 provided with a contents-accommodating section
2110, a temperature control agent 2131 and a liquid reactant
container 2190; a sealing portion 2140, a grip portion 2150 and a
pouch cutting portion 2180.
[0308] The contents-accommodating section 2110 is provided to
accommodate the contents, that is, the temperature controllable
object 10.
[0309] Here, the temperature controllable object 10 includes
various instant food such as the retort pouch. For example, the
contents may include food such as boiled rice, Bibimbap, soup, stew
or dry milk; a pad containing medicine for taking a hot massage or
a cold massage, or a mask pad containing beauty ingredients.
Besides, the contents may be varied as long as it has to be
instantly heated or cooled.
[0310] The contents-accommodating section 2110 includes a first
accommodating section film 2112 and a second accommodating section
film 2114. Between the first accommodating section film 2112 and
the second accommodating section film 2114 is formed an
accommodating space 2116 for accommodating the temperature
controllable object 10. Here, the first accommodating section film
2112 and the second accommodating section film 2114 may be made of
a heat resistant plastic film.
[0311] In more detail, the contents-accommodating section 2110 may
include the plastic film such as polyethylene (PE), polypropylene
(PP), or a polyethyelene terephthalate (PET).
[0312] Of course, the first accommodating section film 2112 and the
second accommodating section film 2114 constituting the
contents-accommodating section 2110 may be made of well-known
synthetic resin films of various materials.
[0313] For example, the first accommodating section film 2112 may
include a CPP film having a thickness of 60 .mu.m, an aluminum film
having a thickness of 9 .mu.m, or a combination film between a
nylon film having a thickness of 15 .mu.m and a CPP film having a
thickness of 60 .mu.m. Of course, this is nothing but illustrative.
The first accommodating section film 112 may include a combination
film of various materials, or as necessary include a film of a
single material. The second accommodating section film 2114 may be
made of the same material as that of the first accommodating
section film 2112.
[0314] The first accommodating section film 2112 and the second
accommodating section film 2114 form an envelope shape as the other
side and both sides connecting one side and the other side are
adhered and sealed so as to open one side. As the first
accommodating section film 2112 and the second accommodating
section film 2114 are adhered, the accommodating space 2116
accommodating the temperature controllable object 10 is formed.
Trough an opening side of the accommodating section 2110, the
temperature controllable object 10 is filled in the accommodating
space 2116, and the opening side is sealed up by the sealing-bar
attachment-preventing portion 2170 to be described later after the
temperature controllable object 10 is completely filled.
[0315] The temperature controller 2130 may be formed at one side
between both sides of the accommodating section 2110.
[0316] The temperature controller 2130 according to the seventeenth
exemplary embodiment as shown in FIG. 30 to FIG. 32 and FIG. 34
includes the temperature control agent 2131 arranged in a
temperature control space 2134 provided in at least one side
between front and back sides of the contents-accommodating section
2110 and heating or cooling the temperature controllable object
(i.e., the contents); a liquid reactant container 2190 arranged in
the temperature control space 2134 and containing the liquid
reactant for exothermically or endothermically reacting with the
temperature control agent 2131; and a temperature control space
forming member 2132 forming the temperature control space 2134 in
which the exothermic or endothermic reaction occurs.
[0317] The temperature control agent 2131 includes the reactant
2131b and the reactant accommodating section 2131a. The temperature
control agent 2131 according to the seventeenth exemplary
embodiment is arranged at one side between both sides of the
contents-accommodating section 2110. The temperature control agent
2131 according to according to an exemplary embodiment is arranged
at a side facing the first accommodating section film 2112. The
temperature control agent 2131 reacts with the liquid reactant w
such as water inserted from the outside.
[0318] The reactant 2131b includes the heating element or the heat
absorption agent in accordance with whether to heat or cool the
temperature controllable object 10 accommodated in the
accommodating section 2110. The reactant 2131b may include at least
one as the heating element among calcium oxide (CaO), calcium
hydroxide (Ca(OH)2), magnesium chloride (MgCl2), iron (Fe) and
aluminum (Al). Here, the reactant 131b may be replaced or changed
by other substances as long as it can exothermally react with the
liquid reactant w.
[0319] On the other hand, the reactant 2131b may include at least
one as the heat absorption agent among ammonium nitrate (NH4NO3),
sodium acetate (CH3COONa) and (urea). Of course, the reactant 131b
may be replaced or changed by other substances as long as it can
endothermally react with the liquid reactant w.
[0320] The reactant accommodating section 2131a accommodates the
reactant 2131b. The reactant accommodating section 131a includes a
body 2131a1 and a partition 2131a2. The reactant accommodating
section 2131a is provided as an absorption fabric to quickly absorb
the liquid reactant w. As necessary, the reactant accommodating
section 2131a may be made of not the absorption fabric but other
substances.
[0321] The body 2131a1 is provided to accommodate the reactant
2131b. Here, the body 2131a1 according to an exemplary embodiment
is partitioned into four accommodating regions by the partition
2131a2. Thus, the reactant 2131b is accommodated in each of the
plurality of accommodating regions partitioned by the partition
2131a2, thereby preventing the reactant 2131b from being leaning by
its own weight. Also, the reactant 2131b is accommodated in each of
the plurality of accommodating regions, and thus the divided
reactant 2131b individually contacts the liquid reactant W1,
thereby making a temperature control reaction quickly.
[0322] The temperature control space forming member 2132, as shown
in FIG. 30, is arranged in a lower side rather than an upper end of
the contents-accommodating section 2110. In more detail, the upper
end of the temperature control space forming member 2132 is lower
than the upper end of the contents-accommodating section 2110.
[0323] The temperature control space forming member 2132 includes a
liquid reactant entrance 2136 through which the liquid reactant
container 2190 is taken out from the temperature control space 2134
and the liquid reactant W1 contained in the liquid reactant
container 2190 is put in.
[0324] The temperature control space forming member 2132 together
with the first accommodating section film 2112 forms the
temperature control space 2134 to accommodate the temperature
control agent 2131 and the liquid reactant container 2190. The
temperature control space 2134 is a space where the exothermic or
endothermic reaction occurs when the liquid reactant W1 contained
in the liquid reactant container 2190 is inserted, and has a margin
space to accommodate the liquid reactant W1 in addition to the
temperature control agent 2131.
[0325] Here, the temperature control space forming member 2132 may
be made of a transparent synthetic resin film so that the liquid
reactant W1, the liquid reactant container 2190 and the temperature
control agent 131 to be inserted can be checked by naked eyes. Of
course, the temperature control space forming member 2132 may be
made of the transparent synthetic resin film with regard to only a
part that can be checked by naked eyes. Of course, the temperature
control space forming member 132 may be partially made of the
transparent synthetic resin film checkable by naked eyes. Of
course, checkability by naked eyes is optional, and thus an opaque
film may be used as necessary. The temperature controller 2130 may
be lower than the accommodating section 2110 so that an upper
opening of the accommodating section 2110 for inserting the
temperature controllable object 10 can be exposed. According to an
exemplary embodiment, the height of the temperature control space
forming member 132 may be eight tenth with respect to the height of
the accommodating section 110.
[0326] The temperature control space forming member 2132 may have
an upper end lower than that of the contents-accommodating section
2110.
[0327] The temperature control space forming member 2132 according
to an exemplary embodiment may be arranged to have a height from
the lower end of the contents-accommodating section 2110 to the
upper end of the temperature control space forming member 2132,
which is lower by 20% than the height from the same position to the
upper end of the contents-accommodating section 2110.
[0328] The temperature control space forming member 2132 may be
made of the plastic film. For example, the temperature control
space forming member 132 may be the plastic film where a PET film
having a thickness of 12 .mu.m and a CPP film having a thickness of
60 .mu.m are combined. Of course, this is nothing but illustrative.
Alternatively, the plastic film may be a combination film where
films of various well-known substances are combined or a single
material film.
[0329] The liquid reactant container 2190 as shown in FIG. 34
includes a liquid reactant the accommodating section 2191 forming
the accommodating space to accommodate the liquid reactant W1; a
liquid reactant outlet 2193 through which the accommodated liquid
reactant flows out; and a liquid reactant container cutting portion
2195 for cutting the liquid reactant outlet 2193.
[0330] The liquid reactant container 2190 may be made of soft or
hard plastic film. According to an exemplary embodiment, the liquid
reactant container 2190 may be an envelope made of a soft plastic
film. As necessary, the liquid reactant container 2190 may be
achieved by sealing a hard plastic film (or plate) and a soft
plastic film with each other.
[0331] The liquid reactant outlet 2193 may have a width narrower
than the liquid reactant the accommodating section 2191. Thus,
through the liquid reactant outlet 2193 having a relatively narrow
width, the liquid reactant W1 can easily flow out in a
predetermined direction.
[0332] The liquid reactant container cutting portion 2195 may
include a notch formed at one side of the liquid reactant outlet
2193. The notch may be replaced by a cutting groove formed along
the cutting direction. Besides, the notch may have various shapes
as long as it can be cut with a hand gripping the liquid reactant
outlet 2193.
[0333] The liquid reactant container cutting portion 2195 may be
cut when a user artificially applies shear force in a width
direction with his/her two hands. Thus, it is possible to prevent
the liquid reactant container cutting portion 2195 from being cut
by mistake while carrying the pouch 22100a.
[0334] The liquid reactant insertion portion 2136 is coupled to the
contents-accommodating section 2110 by the sealing portion 2140 to
be described later, and closes the temperature control space
2134.
[0335] Also, the liquid reactant insertion portion 2136 is provided
to open the temperature control space 2134 closed by the sealing
portion 2140 so that the liquid reactant container 2190 can be
taken out and the liquid reactant W1 contained in the liquid
reactant container 2190 can be put in.
[0336] In more detail, the liquid reactant insertion portion 2136
can be spaced apart from the sealing portion 2140 or the first
accommodating section film 2112 when force of not less than a
predetermined magnitude is applied, in order to take out the liquid
reactant container 2190 from the temperature control space 2134 and
put the liquid reactant W1 of the liquid reactant container 2190.
Thus, the upper side of the temperature control space 2134 is
opened so that the liquid reactant W1 can be put in the temperature
control space 2134.
[0337] The sealing portion 2140 seals up the accommodating section
2110 and the temperature controller 2130, specifically, the liquid
reactant insertion portion 2136, thereby sealing up the temperature
control space 2134. Here, the sealing portion 2140 seals up the
accommodating section 2110 and the liquid reactant insertion
portion 2136 with predetermined intensity of adhesion so that the
temperature control space 2134 can be opened when force of not less
than a predetermined magnitude is applied for spacing the liquid
reactant insertion portion 2136 apart from the accommodating
section 2110. That is, when the liquid reactant insertion portion
2136 is pulled by force stronger than the adhesive strength of the
sealing portion 2140, the temperature control space 2134 is opened.
On the other hand, if force of not less than a predetermined
magnitude is not applied, the sealing due to the sealing portion
2140 is maintained, thereby maintaining the sealed state of the
temperature control space 2134
[0338] Here, the sealing portion 2140 may have an adhesive strength
of not less than 2200 gf/cm.sup.2 and not more than 5 kgf/cm.sup.2.
In experimental results, if the adhesive strength is less than 2200
gf/cm.sup.2, the sealing may not be maintained when the temperature
controllable object 10 is filled and then heated to expand the
temperature control space 2134. On the other hand, the adhesive
strength is more than 5 kgf/cm.sup.2, it is difficult for a regular
adult to open the temperature control space 2134.
[0339] Preferably, the sealing portion 2140 may have a adhesive
strength of 500 gf/cm.sup.2.about.3 kgf/cm.sup.2.
[0340] According to an exemplary embodiment, the sealing portion
2140 is placed on the planar surface of the first accommodating
section film 2112, and seals up between the liquid reactant
insertion portion 136 of the temperature controller 130 and the
first accommodating section film 2112. Thus, the sealing portion
2140 seals up between the first accommodating section film 2112 and
the liquid reactant insertion portion 2136, and prevents foreign
materials from being introduced into the temperature control space
134 while the temperature controllable object 10 is filled in the
accommodating space 2116 of the accommodating section 2110 and then
sterilized. Such sterilization is essential when a retort pouch is
produced by putting stew, soup, boiled rice and the like instant
foods into the pouch 2100.
[0341] Meanwhile, the sealing portion 2140 may be released from the
sealing with the liquid reactant insertion portion 2136 when force
of not less than a certain magnitude is applied for inserting the
liquid reactant W1 into the temperature control space 1134 as
temperature control is required for the temperature controllable
object 10. Then, the liquid reactant insertion portion 2136 is
opened to open the temperature control space 2134, so that the
liquid reactant w can be inserted in the temperature control space
2134. Accordingly, the exothermic or endothermic reaction occurs
between the temperature control agent 2131 and the liquid reactant
W1.
[0342] Here, the sealing portion 2140 may include at least one
among liquid adhesive for adhering the first accommodating section
film 2112 and the liquid reactant insertion portion 2136, a solid
adhesive tape, and an easy peel film provided between the first
accommodating section film 2112 and the liquid reactant insertion
portion 2136.
[0343] Here, the solid adhesive tape may be a film type tape, one
or both sides of which the adhesive is applied to.
[0344] The easy peel film couples both films thereof with
predetermine thermal adhesion when heat of a predetermined
temperature range is applied. Here, the coupling force or adhesion
may be controlled by adjusting the temperature range of heat
applied to the easy peel film.
[0345] Here, the adhesive strength due to the sealing portion 2140
between the liquid reactant entrance 2136 and the accommodating
section 2110 is weaker than contact strength between the
temperature control space forming member 132 and the accommodating
section 2110 besides the liquid reactant entrance 2136.
[0346] In more detail, the liquid reactant entrance 2136 is
expected to be opened so as to insert the liquid reactant in the
temperature control space 2134, and therefore the adhesive strength
of the partial sealing portion C10 between the liquid reactant
entrance 2136 and the accommodating section 2110 may be weaker than
the adhesive strength of the partial sealing portion C9 in a
lateral edge between the temperature control space forming member
2132 and the accommodating section 2110. This may be achieved by
changing the temperature range of the sealing bar used when sealing
the partial sealing portions C9, C10. Such temperature range will
be described later.
[0347] The upper end region of the temperature control space
forming member 2132 and the contents-accommodating section 2110
between which the sealing portion 2140 is interposed are may be
thermally adhered by the sealing bar heated at the first
temperature. Here, the upper end region, which corresponds to the
liquid reactant entrance 2136 of the temperature control space
forming member 2132, seals up the liquid reactant entrance
2136.
[0348] Here, the first temperature may be 150.degree. C. or higher
and 220.degree. C. or lower. If the first temperature of the
sealing bar thermally adhering the upper end regions is lower than
150.degree. C., the thermal adhesive strength of the liquid
reactant entrance 2136 is so weak that the sealability of the
temperature control space 2134 between the temperature control
space forming member 2131 and the contents-accommodating section
2110 is deteriorated to thereby allowing external foreign materials
(e.g., moisture or the like) to be introduced therein.
[0349] On the other hand, if the first temperature is higher than
220.degree. C., the thermal adhesive strength of the liquid
reactant entrance 2136 is so strong that it is difficult for a user
to open the temperature control space 2134.
[0350] Meanwhile, the partial sealing portion C9 of the left, right
and lower edge regions between the temperature control space
forming member 2132 and the contents-accommodating section 2110 may
be thermally adhered by the sealing bar heated at the second
temperature.
[0351] Here, the second temperature may be 230.degree. C. or higher
and 2300.degree. C. or lower.
[0352] Here, the first temperature is lower than the second
temperature. As described above, this is to make a user easily open
the temperature control space 134 while keeping its sealing as the
thermal adhesive strength of the liquid reactant entrance 136
expected to be open is weaker than the other portions (i.e., the
left, right and lower edges).
[0353] Meanwhile, the grip portion 2150 is provided to allow a user
to easily grip the liquid reactant insertion portion 2136 of the
temperature controller 2130. The grip portion 2150 may be extended
from the liquid reactant insertion portion 2136 and may be formed
integrally with the liquid reactant insertion portion 2136.
[0354] The grip portion 2150 may protrude from the liquid reactant
insertion portion 2136. The grip portion 2150 may be provided in
the center region of the liquid reactant insertion portion 2136.
The grip portion 2150 protrudes from the center region of the
liquid reactant insertion portion 2136 and is gripped by a user. In
particular, the grip portion 2150 is gripped by a user and
transfers a user's force to the liquid reactant insertion portion
2136 so that the liquid reactant insertion portion 2136 can be
released from the accommodating section 2110. To make a user easily
grip the grip portion 2150 and efficiently transfer his/her force,
the grip portion 2150 may protrude from the center portion of the
liquid reactant insertion portion 2136.
[0355] Of course, the grip portion 2150 be plurally provided at
both sides of the liquid reactant insertion portion 136.
[0356] As shown in FIG. 31, the upper end portions of the first and
second accommodating section films 2112, 2114 are not sealed so
that the temperature controllable object 10 can be put into the
contents-accommodating section 2110 along the inserting direction
B1 in the state that the upper portion of the
contents-accommodating section 2110 is opened.
[0357] To heat or cool the temperature controllable object 10
accommodated in the contents-accommodating section 2110, as shown
in FIG. 33, a user first grips the grip portion 2150 and pulls the
liquid reactant entrance 2136 in a direction of F1, thereby spacing
it apart from the accommodating section 2110. At this time, if
force of not less than a predetermined magnitude is applied for
spacing the liquid reactant entrance 2136 apart from the
accommodating section 2110, that is, stronger than the adhesive
strength due to the sealing portion 2140, the liquid reactant
entrance 2136 is opened. As described above, the thermal adhesive
strength in the sealing region C10 due to the sealing portion 150
is weaker than the thermal adhesive strength of the edge portion C9
of the accommodating section 2110, and therefore the liquid
reactant entrance 2136 can be more easily opened than other
portions.
[0358] In the state that the temperature control space 2134 is
being opened, the liquid reactant container 2190 is taken out from
the temperature control space 2134 and the liquid reactant
container 2190 is cut using the liquid reactant container cutting
portion 2195 of the liquid reactant container 2190. From the cut
liquid reactant container 2190, the liquid reactant is put into the
temperature control space 2134. Accordingly, the exothermic or
endothermic reaction occurs between the liquid reactant and the
temperature control agent 2131 within the temperature control space
2134, so that the temperature controllable object 10 accommodated
in the accommodating space 2116 can be heated or cooled. As a
proper amount of the liquid reactant contained in the liquid
reactant container 2190 reacts with the temperature control agent
2131, the optimal exothermic or endothermic reaction may occur.
[0359] After a lapse of predetermined time, a user uses the grip
portion 2180 to cut open the upper end of the accommodating section
2110. Thus, a user takes in, takes out or uses the heated or cooled
temperature controllable object 10 through the accommodating
section 2110 having the opened upper portion.
[0360] Meanwhile, the foregoing illustrates that the lateral edges
D6 of the first accommodating section film 2112 and the second
accommodating section film 2114 of the contents-accommodating
section 2110 are directly sealed up. As necessary, the cross
section of the lateral edges may be creased like "" so that a user
can more easily grip the lateral side of the pouch 2100. This may
be achieved by interposing a separate film between the lateral
edges of the first accommodating section film 2112 and the second
accommodating section film 2114 and thus broadening both edges.
Eighteenth Exemplary Embodiment
[0361] A pouch 2200 according to the eighteenth exemplary
embodiment, as shown in FIG. 35 to FIG. 37 includes a
contents-accommodating section 2210 having a contents-accommodating
space S6 to accommodate the contents; a temperature controller 2220
provided in at least one side between the front and back sides of
the contents-accommodating section 2210 to heat or cool the
contents-accommodating section 2210; and a sealing portion 2230
sealing up a liquid reactant entrance 2222 communicating the
temperature control spaces S7, S8 in the temperature controller
2220.
[0362] The contents-accommodating section 2210 includes a first
accommodating section film 2211 and a second accommodating section
film 2213 to form the contents-accommodating space S6.
[0363] The first accommodating section film 2211 and the second
accommodating section film 2213 may be made of a plastic film. In
more detail, the plastic film may include polyethylene (PE),
polypropylene (PP), or a polyethyelene terephthalate (PET).
Besides, the first accommodating section film 2211 and the second
accommodating section film 2213 may be made of well-known synthetic
resin films of various materials.
[0364] The temperature controller 2220 couples with the
contents-accommodating section 2210, in more detail, couples with
the contents-accommodating section 2210 so as to form the
temperature control spaces S7, S8 provided in at least one side
between the front and rear sides with respect to the
contents-accommodating space S6.
[0365] FIG. 35 to FIG. 37 illustrate that the temperature control
spaces S7, S8 are formed in front and back, but not limited
thereto. As necessary, the temperature control spaces S7, S8 may be
formed at only one side.
[0366] The temperature controller 2220 includes a second front film
2221 coupled in the front of the contents-accommodating section
2210 and forming the temperature control space S7 in a front side;
and a second back film 2224 coupled in the back of the
contents-accommodating section 2210 and forming the temperature
control space S8 in a back side.
[0367] The first temperature control space forming member 2221 and
the second temperature control space forming member 2224 may be
made of a plastic film such as polyethylene (PE), polypropylene
(PP), or a polyethyelene terephthalate (PET). Besides, the first
temperature control space forming member 2221 and the second
temperature control space forming member 2224 may be made of
well-known synthetic resin films of various materials.
[0368] Here, the temperature control spaces S7, S8 are isolated
from the contents-accommodating space S6.
[0369] The front and back temperature control spaces S7, S8 can
communicate with each other through a communication space S9. The
communication space S9 may be formed by arranging the
contents-accommodating section 2210 so that the lower end portion
2211c of the contents-accommodating section 2210 can be spaced
apart from the lower end portion D6 of the temperature controller
2220. In this case, the lower end portion D6 of the temperature
controller 2220 is a part where the respective lower end portions
of the first temperature control space forming member 2221 and the
second temperature control space forming member 2224 are coupled by
ultrasonic waves or thermal welding. Of course, coupling between
the plastic films may be achieved various well-known methods
besides the foregoing ultrasonic waves or thermal welding.
[0370] Meanwhile, the contents-accommodating section 2210 and the
temperature controller 2220 may be coupled with each other at left
and right end portions D6, D7 by ultrasonic waves or thermal
welding.
[0371] The temperature controller 2220 includes a plurality of
temperature control agents 2223, 2225 respectively arranged in the
plurality of temperature control spaces S7, S8.
[0372] As described above, if the temperature control spaces, S8
are formed at only one side between front and back sides, the
temperature control agents 2223, 2225 may be arranged at only one
corresponding side.
[0373] Here, the temperature control agents 2223, 2225 includes
heating elements 2223a, 2225a to exothermically react with the
liquid reactant, and absorption fabrics 2223b, 2225b surrounding
the heating elements 2223a, 2225a and absorbing the liquid reactant
to make the exothermic reaction smoothly.
[0374] As necessary, the absorption fabrics 223b, 225b may be
omitted.
[0375] Also, a heat absorption agent endothermically reacting with
the liquid reactant may be used instead of the heating elements
2223a, 2225a. The heating element and the heat absorption agent
react with the liquid reactant to heat and cool the contents
accommodated in the contents-accommodating space S6.
[0376] The heating element may include at least one among calcium
oxide, calcium hydroxide, magnesium chloride, iron, and aluminum.
Of course, the foregoing substances may be replaced or changed by
other substances as long as it can react with the liquid
reactant.
[0377] The heat absorption agent may include at least one of
ammonium nitrate (NH4NO3), sodium acetate and urea.
[0378] Here, the plurality of temperature control agents 2223, 2225
may all include only the heating elements, or only the heat
absorption agent.
[0379] As necessary, in the plurality of temperature control agents
2223, 2225, the front temperature control agent 2223 may include
only the heating element, and the back temperature control agent
2225 may include only the heat absorption agent. In this case, the
front and back temperature control spaces S7, S8 may not
communicate with each other but isolated from each other with the
contents-accommodating space S6 therebetween.
[0380] The temperature controller 2220 may further include the
liquid reactant container 2190 arranged in the temperature control
spaces S7, S8.
[0381] If the temperature control spaces S7, S8 communicate with
each other, the liquid reactant container 2190 may be provided in
only the temperature control space S7 formed with the liquid
reactant entrance 2222 to be described later. If the liquid
reactant entrances 2222 are respectively formed at both sides of
the plurality of temperature control space S7, S8, the liquid
reactant container 2190 may be provided in each of the temperature
control spaces S7, S8.
[0382] The temperature controller 2220 may further include the
liquid reactant entrance 2222 through which the liquid reactant
container 2190 is taken out from the temperature control spaces S7,
S8 and the liquid reactant (refer to W1 of FIG. 34) of the liquid
reactant container 2190 is put in.
[0383] The liquid reactant entrance 2222 is sealed up by the
sealing portion 2230 so as to be openable.
[0384] Also, the liquid reactant entrance 2222 is arranged at a
lower side of the contents-accommodating section 2210 rather than
an upper end thereof. That is, an upper edge of the liquid reactant
entrance 2222 is lower than the upper end of the
contents-accommodating section 2210 so that a user can easily check
the position of the liquid reactant entrance 2222 with his/here
naked eyes.
[0385] The liquid reactant entrance 222 may be formed as a partial
upper end section G1 of the first temperature control space forming
member 2221 of the temperature controller 2220 is not coupled with
the first accommodating section film 2211. At this time, the first
temperature control space forming member 2221 of the remaining
upper end section D8 may be permanently sealed up with the first
accommodating section film 2211.
[0386] Here, the liquid reactant entrance 222 the partial upper end
section G of the second front film 221. As necessary, the liquid
reactant entrance 222 may be formed in the entire upper end section
of the second front film 221.
[0387] Here, the drawings illustrate the liquid reactant entrance
2222 is formed in the partial upper end section G1 of the first
temperature control space forming member 2221. As necessary, the
liquid reactant entrance 222 may be formed in the entire upper end
section of the first temperature control space forming member
2221.
[0388] Also, the height of the liquid reactant entrance 2222 from
the lower end of the pouch may be relatively greater than that of
the remaining section D8 of the first temperature control space
forming member 2221 from the lower end of the pouch 2200. Of
course, the liquid reactant entrance 2222 may have the same height
as the remaining section D8 of the first temperature control space
forming member 2221.
[0389] The pouch 2200 may include a grip portion 2222a extended
frontward so that a user can easily grip the liquid reactant
entrance 2222 with his/her hand. Thus, a user can easily grip and
open the liquid reactant entrance 2222.
[0390] Here, the grip portion 2222a may be as shown in FIG. 37
formed to be folded down from the first accommodating section film
2211.
[0391] As necessary, instead of the grip portion 2222a of FIG. 37,
the upper end of the first temperature control space forming member
2221 may be provided as it is spaced apart from the
contents-accommodating section 2210, specifically from the first
accommodating section film 2211 by a predetermined space K. Thus, a
user puts his/her fingers in the space and broadens the liquid
reactant entrance 2222, thereby opening the liquid reactant
entrance 2222.
[0392] Meanwhile, the sealing portion 2230 seals up the liquid
reactant entrance 2222 as long as the liquid reactant entrance 2222
is not spaced from the contents-accommodating section 2210 by force
of not less than a predetermined magnitude. Thus, it is possible to
prevent foreign materials from entering the liquid reactant
entrance 2222 while the contents is put into and sterilized in the
contents-accommodating section S6 of the pouch 2200. Such
sterilization is essential when a retort pouch is produced by
putting stew, soup, boiled rice and the like instant foods into the
pouch 2200.
[0393] Accordingly, the pouch 2200 according to an exemplary
embodiment facilitates the manufacture of the retort pouch.
[0394] As shown in FIG. 37, the sealing portion 2230 may be
provided between the first temperature control space forming member
2221 and the first accommodating section film 2211 at a side lower
than the grip portion 2222a of the liquid reactant entrance
2222.
[0395] The sealing portion 2230 may be provided to allow opening
between the first accommodating section film 2211 and the first
temperature control space forming member 2221 when force of not
less than a predetermined magnitude is applied thereto. In other
words, if external force of not less than a predetermined magnitude
is applied, the sealing portion 2230 may open the liquid reactant
entrance 2222. Thus, if a user grips and then pulls the grip
portion 2222a by force of not less than a predetermined magnitude,
the liquid reactant entrance 2222 is opened.
[0396] A user takes out and cuts the liquid reactant container 2190
from the open liquid reactant entrance 2222, and puts the liquid
reactant (refer to W1 of FIG. 34, for example, water) into the
temperature control space S7, thereby heating or cooling the
contents accommodated in the contents-accommodating space S6.
[0397] Here, the liquid reactant (refer to W1 of FIG. 34) put into
the temperature control space S7 causes the exothermic or
endothermic reaction while moving to another temperature control
space S8 through the communication space S9.
[0398] Also, since the liquid reactant entrance 2222 is easily
opened to put the liquid reactant, it is convenient for a user.
[0399] The sealing portion 2230 may be made of the same material as
the sealing portion 2140 of the foregoing seventeenth exemplary
embodiment. In more detail, the sealing portion 2230 may include at
least one among liquid adhesive, a solid adhesive tape, and an easy
peel film arranged between the first accommodating section film
2112 and the liquid reactant insertion portion 2136.
[0400] As necessary, the sealing portion 2230 may be formed by
fusing the first accommodating section film 2211 and the first
temperature control space forming member through thermal welding or
ultrasonic waves. At this time, the first accommodating section
film 2211 and the first temperature control space forming member
2221 may be fused to such an extent as to be separated from each
other when the sealing portion 2230 receives external force of a
predetermined magnitude.
[0401] Of course, the sealing portion 2230 may be varied as long as
it can seal up the liquid reactant entrance and prevent foreign
materials, such as liquid (e.g., water), from being introduced
therein if there is no external force of not less than a
predetermined magnitude.
[0402] Meanwhile, the pouch 2200 may further include a ziplock 2260
to selectively seal up the upper portion of the
contents-accommodating section 2210. As necessary, the ziplock 2260
may be omitted.
[0403] The ziplock 2260 includes a female zipper 2261 formed inside
the first accommodating section film 2211 and a male zipper 2263
formed inside of the second accommodating section film 2213. Of
course, the positions of the female zipper 2261 and the male zipper
2263 may be exchanged.
[0404] Also, various well-known sealing means may be employed
instead of the ziplock 2260 as long as it can selectively seal up
the contents-accommodating section 2210.
[0405] Meanwhile, the pouch 2200 may further include a transparent
window 2215, 2216, 2217 for checking whether the
contents-accommodating space S6 is sealed up or not. That is, the
defect of the contents-accommodating section 210 can be determined
by naked eyes through the transparent windows 2215, 2216, 2217.
[0406] As shown in FIG. 35, the transparent window 2215 may be
arranged between the liquid reactant entrance 2222 and the upper
end of the first accommodating section film 2211. Through the
transparent window 2215, contact between the first accommodating
section film 2211 and the contents accommodated therein is checked
by naked eyes, and it is thus possible to determine whether a
product is defective or not. For example, if solid food is put into
the contents-accommodating section 2210 and then the
contents-accommodating space S6 is vacuumized, it is possible to
determine by naked eyes through the transparent window 2215 whether
there is a trouble in the vaccumization.
[0407] Meanwhile, the transparent window 216 may be as shown in
FIG. 35 and FIG. 36 formed in a lower portion of the pouch 2200. If
the contents accommodated in the contents-accommodating section
2210 is liquid and the liquid leaks out because the
contents-accommodating section 2210 is defective, it is possible to
determine by naked eyes through the transparent window 2216 of the
lower portion whether the product is defective or not. To make it
easier to determine through the transparent window 2216 of the
lower portion whether the contents-accommodating section 2310 is
sealed up or not, a corresponding region of the first temperature
space forming member 2221 formed with the transparent window 2216
may be transparently formed, but a corresponding region of the
first temperature space forming member 2221 may be opaque. For
example, the first temperature space forming member 2221 may be
entirely made of a transparent film, while the first accommodating
section film 2211 may be entirely made of an opaque film.
[0408] Also, the transparent window 2217 formed in a vertical
direction may be as shown in FIG. 35 formed at one side between
left and right sides of the pouch 2200 along a lengthwise
direction. Thus, a user leans the pouch 2200 and checks by his/her
naked eyes through the transparent window 2217 whether the contents
accommodated in the contents-accommodating section 2210 leak out or
not, thereby determining whether a product is defective or not.
[0409] The plurality of transparent windows 2215, 2216, 2217 are to
check whether the contents-accommodating space S6 of the
contents-accommodating section 2210 is surely isolated from the
temperature control spaces S7, S8. If it is checked through the
plurality of transparent windows 2215, 2216, 2217 that there is no
defect in a product, the contents of the contents-accommodating
space S6 is not affected by a byproduct produced by the exothermic
or endothermic reaction within the temperature control spaces S7,
S8.
[0410] The drawings show the plurality of transparent windows 2215,
2216, 2217, but the number and positions of the transparent windows
2215, 2216, 2217 may be varied.
[0411] Meanwhile, the foregoing description illustrates that the
liquid reactant entrance 2222 is formed at only one side between
the front and back sides, but not limited thereto. Alternatively,
the liquid reactant entrance 222 may be formed at both the front
and back sides.
Nineteenth Exemplary Embodiment
[0412] The pouch 2200a according to the nineteenth exemplary
embodiment as shown in FIG. 38 and FIG. 39 includes the
contents-accommodating section 2210; the temperature controller
2220 and a sealing portion 2240.
[0413] The nineteenth exemplary embodiment is the same as the
eighteenth exemplary embodiment except that the ziplock 2260 is
omitted and the sealing portion 2240 is arranged in a different
position.
[0414] The sealing portion 2240 of the nineteenth exemplary
embodiment may includes an adhesive tape 2240 attached to the upper
end outside of the liquid reactant entrance 2222 and sealing up the
temperature control space S7. Thus, it is possible to prevent
foreign materials (in particular, liquid) from being introduced
into the temperature control spaces S7, S8 while contents are put
into the contents-accommodating section S6 and sterilized after the
upper end of the contents-accommodating section S6 is sealed
up.
[0415] Meanwhile, the adhesive tape 2240 includes a tape grip
portion 2241 extended so that its one side can be gripped. Thus, if
a user pulls the tape grip portion 2241 and removes the adhesive
tape 2240, the liquid reactant of the liquid reactant container
2190 accommodated in the temperature control space S7 can be easily
put into the pouch 2200b.
Twentieth Exemplary Embodiment
[0416] A pouch 2300 according to a twentieth exemplary embodiment
as shown in FIG. 40 includes a contents-accommodating section
accommodating section 2110; a temperature controller 2330 provided
with a plurality of temperature control agents 2131 respectively
arranged in a first accommodating section film 2112 and a second
accommodating section film 2114; a sealing portion 2140 sealing up
the plurality of temperature control spaces 2334, 2335
accommodating the plurality of temperature control agents 2131 and
the plurality of liquid reactant container 2190; and a pouch stand
2790 arranged in lower portions of the first accommodating section
film 2112 and the second accommodating section film 2114 and
allowing the pouch 2300 to stand.
[0417] The temperature controller 2330 includes a first temperature
control space forming member 2331, a second temperature control
space forming member 2332, a first liquid reactant insertion
portion 2337 and a second liquid reactant insertion portion
2338.
[0418] The first temperature control space forming member 2331 and
the second temperature control space forming member 2332 are
respectively opposite to the first accommodating section film 2112
and the second accommodating section film 2114. Between the first
temperature control space forming member 2331 and the first
accommodating section film 2112 and between the second temperature
control space forming member 2332 and the second accommodating
section film 2114 are respectively formed a first temperature
control space 2334 and a second temperature control space 2335.
Here, the first temperature control space 2334 and the second
temperature control space 2335 accommodate the temperature control
agent 2131 and the liquid reactant container 2190,
respectively.
[0419] Further, the first liquid reactant insertion portion 2337
and the second liquid reactant insertion portion 2338 are provided
in the upper regions of the first temperature control space forming
member 2331 and the second temperature control space forming member
2332 to open and close the respective temperature control spaces
2334, 2335.
[0420] The sealing portion 340 is provided to seal up the first
temperature control space 2334 and the second temperature control
space 2335 by the first liquid reactant insertion portion 2337 and
the second liquid reactant insertion portion 2338, respectively.
The sealing portion 340 includes the first sealing portion 2342 for
sealing up between the first accommodating section film 2112 and
the first liquid reactant insertion portion 2337, and the second
sealing portion 2344 for sealing up between the second
accommodating section film 2114 and the second liquid reactant
insertion portion 2338. Here, the first sealing portion 2342 and
the second sealing portion 2344 may include the liquid adhesive,
the solid adhesive tape or the easy peel film, like the sealing
portion 2140 of the seventeenth exemplary embodiment and
[0421] The grip portion 2350 includes the first grip portion 2352
and the second grip portion 2354 respectively connected to the
first liquid reactant insertion portion 2337 and the second liquid
reactant insertion portion 2338 and gripped to open the first
temperature control space 2334 and the second temperature control
space 2335. The first grip portion 2352 may be arranged in the
center region of the first liquid reactant insertion portion 2337,
and the second grip portion 2354 may also be arranged in the center
region of the second liquid reactant insertion portion 2338. The
first grip portion 2352 and the second grip portion 2354 have the
same shape as the grip portion 2150 of the seventeenth exemplary
embodiment. Of course, the first grip portion 2352 and the second
grip portion 2354 may have different shapes from that of the grip
portion 2150 of the seventeenth exemplary embodiment.
[0422] As described above, the pouch 2300 according to the
twentieth exemplary embodiment accommodates two temperature control
agents 2131 in two temperature control spaces 2334, 2335 as opposed
to the seventeenth exemplary embodiment. Accordingly, the pouch
2300 according to the twentieth exemplary embodiment can more
quickly control the temperature of the temperature controllable
object 10 than the pouch 2100 according to the seventeenth
exemplary embodiment.
[0423] Meanwhile, the sealing portion 2140 includes the first
sealing portion 2141 for sealing the first temperature control
space 2334, and the second sealing portion 2143 for sealing the
second temperature control space 2335.
[0424] The first and second sealing portions 141, 143 may be made
of the same material as the sealing portion 2140 according to the
foregoing seventeenth exemplary embodiment.
[0425] The first and second sealing portions 2141, 2143 seal up
between the first temperature control space forming member 2331 and
the first accommodating section film 2112 and between the second
temperature control space forming member 2332 and the second
accommodating section film 2114 so that the first and second liquid
reactant entrances 2337, 2338 can be opened when force of not less
than a certain magnitude is applied to space the first and second
liquid reactant entrances 2337, 2338 apart from the
contents-accommodating section 2110.
[0426] Here, as shown in FIG. 40, a user may use the first grip
portion 2352 and the second grip portion 2354 to open the first and
second temperature control spaces 2334, 2335, respectively. In the
state that the first and second temperature control spaces 2334,
2335 are opened, the liquid reactant container 2190 is taken out
and cut, and the liquid reactant therein is put into the first and
second temperature control spaces 2334, 2335. Thus, the exothermic
or endothermic reaction occurs in the first and second temperature
control spaces 2334, 2335, thereby heating or cooling the
temperature controllable object within the accommodating space
2116.
Twenty-First Exemplary Embodiment
[0427] A pouch 2300a according to a twenty-first exemplary
embodiment as shown in FIG. 41 includes a contents-accommodating
section 2110a including the first accommodating section film 2112,
the second accommodating section film 2114 and the spacing film 115
spaced apart from the pouch stand 2790; the temperature controller
230 provided with the plurality of temperature control agents 2131
respectively arranged in the first accommodating section film 2112
and the second accommodating section film 2114; the sealing portion
2140 for sealing up one among the plurality of temperature control
spaces 2234, 2235 accommodating the plurality of temperature
control agents 2131; the grip portion 2150; the sealing-bar
attachment-preventing portion 2170, and the pouch cutting portion
(refer to 2180 in FIG. 30).
[0428] The first and second accommodating section films 2112, 114
and the spacing film 115 of the contents-accommodating section
2110a may be all provided a single film. As necessary, they may be
manufactured with individually cut films and then sealed.
[0429] The temperature controller 2230 includes the first and
second temperature control space forming members 2231, 2232
respectively sealed with the first and second accommodating section
films 2112, 114 to form the first and second temperature control
spaces 2234, 2234; the plurality of temperature control agents 2131
respectively accommodated in the first and second temperature
control spaces 2231, 2232; and the liquid reactant container 2190
accommodated in the first temperature control space 2231.
[0430] The first temperature control space forming member 2231 has
an upper end arranged to be lower than the upper end of the
contents-accommodating section 2110.
[0431] The first temperature control space forming member 2231
includes the liquid reactant entrance 2237 through which the liquid
reactant exothermically or endothermically reacting with the
temperature control agent 2131 can be inserted in the first
temperature control space 231.
[0432] The sealing portion 2140 is provided between the liquid
reactant entrance 2237 and the first accommodating section film
2112 of the first temperature control space forming member
2231.
[0433] The liquid reactant entrance 2237, the sealing portion 2140
and the first accommodating section film 2112 are thermally adhered
by heat to be sealed.
[0434] When the upper ends of the first accommodating section film
2112 and the second accommodating section film 2114 are sealed up
by the sealing bar having a predetermined sealing temperature in
order to seal up the upside of the contents-accommodating section
2110, the first accommodating section film 2112 may be attached to
and not separated from the sealing bar.
[0435] The sealing-bar attachment-preventing portion 2170 prevents
the first accommodating section film 2112 from being attached to
and not separated from the sealing bar.
[0436] In more detail, the first accommodating section film 2112 is
as described above made of a single CPP film or a combination film
where the CPP film is exposed. The CPP film may be sticked to and
not well separated from the sealing bar, and to prevent this, the
sealing-bar attachment-preventing portion 2170 may be provided on
the first accommodating section film 2112 contacting the sealing
bar.
[0437] The PET substance may be used as a material not well
attached to the sealing bar. The sealing-bar attachment-preventing
portion 2170 may include a film of which a part exposed in a
direction of pressing the sealing bar, i.e, frontward is combined
with the PET film, or a single PET film.
[0438] For example, the sealing-bar attachment-preventing portion
2170 may be the same plastic film as the foregoing temperature
control space forming member 2132, where the PET film having a
thickness of 12 .mu.m and the CPP film having a thickness of 60
.mu.m are combined. Here, the PET film has to be arranged to be
exposed frontward so that the PET film can contact the sealing
bar.
[0439] Here, it is just illustrative that the PET is used as a
material for the sealing-bar attachment-preventing portion 2170.
The PET may be replaced by the plastic films of various well known
materials as long as it cannot well attached to the sealing
bar.
[0440] After the temperature controllable object (i.e., the
contents) is filled while the accommodating section 2110a is being
opened, the sealing bar heated at a predetermined temperature
applies heat toward the sealing-bar attachment-preventing portion
2170 along the upper edges of the accommodating section 2110,
thereby sealing up the upper end of the accommodating section 2110.
Accordingly, it is possible to prevent the accommodating section
2110 from being attached to the sealing bar.
[0441] The sealing-bar attachment-preventing portion 2170, the
first temperature control space forming member 2231 and the second
temperature control space forming member 2232 may be all made of
the same material. For example, each of the sealing-bar
attachment-preventing portion 2170, the first temperature control
space forming member 2231 and the second temperature control space
forming member 2232 may be the plastic film where the PET film
having a thickness of 12 .mu.m and the CPP film having a thickness
of 60 .mu.m are combined.
[0442] Meanwhile, the pouch cutting portion 2180 may be provided
between the liquid reactant insertion portion 2237 and the
sealing-bar attachment-preventing portion 2170.
[0443] The pouch cutting portion 2180 may include a notch in a
transverse direction at one or both sides of the
contents-accommodating section 2110 so that the
contents-accommodating section 2110 can be torn when transverse
force of not less than a certain magnitude is applied.
[0444] The cutting portion may be arranged in a relatively thin
position so that the pouch cutting portion (refer to 2180 in FIG.
30) can be easily torn through the notch.
[0445] In more detail, as shown in FIG. 41, the sealing-bar
attachment-preventing member 2170 and the liquid reactant insertion
portion 2237 may be spaced apart from each other so that a cutting
region A7 where the pouch cutting portion (refer to 2180 in FIG.
30) with the notch is provided can be relatively thin.
[0446] That is, the cutting region A7 includes only the first
accommodating section film 2112 and the second accommodating
section film 2114, and it is therefore thinner than three layered
films of the sealing-bar attachment-preventing member 170, the
first and second accommodating section films 2112, 2114 provided at
the upper side of the contents-accommodating section 2110.
[0447] Also, total four films of the temperature control space
forming member 2231, the sealing portion 2140, the first
accommodating section film 2112 and the second accommodating
section film 2114 are provided under the cutting region A7, and
therefore the cutting region A7 having two layered films is
relatively thin. Thus, the contents-accommodating section 2110a can
be more easily cut by the pouch cutting portion (see 2180 in FIG.
30) formed in the cutting region A7.
[0448] To heat or cool the temperature controllable object, a user
grips the grip portion 2150 and applies force to the liquid
reactant entrance 2237, thereby opening the first temperature
control space 2234. Further, the liquid reactant container 2190 is
taken out and cut from the open first temperature control space
2234, and the liquid reactant is inserted in the opened first
temperature control space 2234. The liquid reactant put into the
first temperature control space 2234 is introduced into a second
temperature control space 235 through a communication space H1
between the liquid reactant the accommodating section 2110 and the
pouch stand 2790. Thus, the exothermic or endothermic reaction can
occur between the liquid reactant and the temperature control agent
2131 within even the second temperature control space 2235.
[0449] In the case of the pouch 300b according to the twenty-first
exemplary embodiment, even though a user opens not both the
temperature control spaces 2234, 2235 but one of them to insert the
liquid reactant, the inserted liquid reactant can be transferred to
the unopened space. Accordingly, it is convenient for a user.
[0450] Meanwhile, the sealing-bar attachment-preventing portion
2170 and the pouch cutting portion 2180 described above are not
essential, and all or a part of the foregoing elements 2170, 2180
may be omitted.
Twenty-Second Exemplary Embodiment
[0451] The pouch 2100b according to the sixth exemplary embodiment
as shown in FIG. 42 includes the contents-accommodating section
2110, the temperature controller 2130, the sealing portion 2240,
the grip portion 2150, the sealing-bar attachment-preventing
portion 2170 and the cutting portion (see 2180 in FIG. 30).
[0452] The pouch 2100b according to the twenty-second exemplary
embodiment is different from the pouch 2100 of the seventeenth
exemplary embodiment in the shape of the sealing portion 2140
according to the seventeenth exemplary embodiment.
[0453] The sealing portion 2240 may be provided to cover the entire
of the first accommodating section film 2112 of the
contents-accommodating section 2110.
[0454] In the case of the pouch 2100 according to the seventeenth
exemplary embodiment, the sealing portion 2140 has a predetermined
width as shown in FIG. 31. On the other hand, the sealing portion
2240 according to the eighth exemplary embodiment is provided to
cover the entire front side of the contents-accommodating section
2110.
[0455] Here, the sealing portion 2240 may include at least one
among the liquid or solid adhesive tape for adhesion between the
first accommodating section film 2112 and the liquid reactant
insertion portion 2136, and the easy peel film arranged between the
first accommodating section film 2112 and the liquid reactant
insertion portion 2136.
[0456] Here, the solid adhesive tape may be a film type tape, one
or both sides of which the adhesive is applied to.
[0457] The easy peel film couples both films thereof with
predetermine thermal adhesion when heat of a predetermined
temperature range is applied. Here, the coupling force or adhesion
may be controlled by adjusting the temperature range of heat
applied to the easy peel film.
[0458] In the case of the twenty-second exemplary embodiment, the
sealing portion 2240 is provided to cover the entire of the first
accommodating section film 2112, and therefore there is no need of
position control work for positioning the sealing portion 2240 to a
certain position between the liquid reactant entrance 2136 and the
first accommodating section film 2112. For reference, in the case
of the sealing portion 2140 according to the seventeenth exemplary
embodiment shown in FIG. 31, it is positioned at only a specific
portion, and therefore there is a need of work for positioning the
sealing portion 2140 to the corresponding position.
Twenty-Third Exemplary Embodiment
[0459] A pouch 1000 according to a twenty-third exemplary
embodiment as shown in FIG. 43 and FIG. 44 includes a
contents-accommodating section 1100 for accommodating contents, and
a temperature controller 1200 provided with temperature control
agent 1210 and the liquid reactant insertion portions 1230,
1240.
[0460] The contents CA1 may include retort pouch such as solid
boiled rice, Bibimbap, liquid soup, stew or dry milk; a pad
containing medicine for taking a hot massage or a cold massage, or
a mask pad containing beauty ingredients. Besides, the contents may
be variously selected as long as it has to be instantly heated or
cooled. Besides the foregoing retort pouch, the food needed for
sterilization for prolong expiration date may also be included in
the contents CA1 regardless of the kind or types.
[0461] The contents-accommodating section 1100 may form a
contents-accommodating space SP1 where the contents CA1 are
accommodated.
[0462] The contents-accommodating section 1100 includes the first
accommodating section film 1110 and the second accommodating
section film 1120.
[0463] The first accommodating section film 112 and the second
accommodating section film 114 may be made of the plastic film.
[0464] In more detail, the first accommodating section film 1110
and the second accommodating section film 1120 may be made of the
plastic film such as polyethylene (PE), polypropylene (PP), or a
polyethyelene terephthalate (PET). Of course, the first
accommodating section film 112 and the second accommodating section
film 114 constituting the accommodating section 110 may be made of
well-known synthetic resin films of various materials.
[0465] For example, the first accommodating section film 1110 may
include a CPP film having a thickness of 60 .mu.m, an aluminum film
having a thickness of 9 .mu.m, or a combination film between a
nylon film having a thickness of 15 .mu.m and a CPP film having a
thickness of 60 .mu.m. Of course, this is nothing but illustrative.
The first accommodating section film 1110 may include a combination
film of various materials, or as necessary include a film of a
single material. The second accommodating section film 1120 may be
made of the same material as that of the first accommodating
section film 1110. As necessary, the second accommodating section
film 1120 may be made of different materials from the first
accommodating section film 1110.
[0466] The left, right and lower ends SA2, SA3, SA4 of the first
accommodating section film 1110 and the second accommodating
section film 1120 are sealed up to form the contents-accommodating
space SP1.
[0467] The upper end of the contents-accommodating space SP1 may be
opened to put the contents CA1 therein. After the contents CA1 is
put in the contents-accommodating space SP1, the upper end of the
contents-accommodating space SP1 may be sealed. A sealing method
may includes a method of using the sealing bar to fuse two films
1110, 1120 with heat, or a method of fusing two films 1110, 1120
with ultrasonic waves or microwaves. Besides, if the contents are
not food, two films 1110, 1120 may be sealed up by adhesive or an
adhesive film. Besides the foregoing sealing methods, well-known
various sealing methods may be employed.
[0468] As necessary, if the contents CA1 are solid food or a pad
for beauty or treatment, the upper end of the
contents-accommodating space SP1 may not be sealed. Also, in the
case that food to be heated or cooled is put into the
contents-accommodating space SP1 of the pouch 1000 and then
directly the liquid reactant is inserted in the temperature control
space SP2 formed by the temperature controller 1200, the upper end
of the contents-accommodating space SP1 may not be sealed.
[0469] As shown in FIG. 44, the temperature controller 1200 is
arranged in a front side of the contents-accommodating section 1100
and forms the temperature control space SP2. Of course, as
necessary, the temperature controllers 1200 may be arranged in the
back side as well as the front side, and thus form the temperature
control space at opposite sides with the contents-accommodating
section 1100 therebetween.
[0470] The temperature controller 1200 includes the temperature
control agent 1210 to be accommodated in the temperature control
space SP2; and the temperature control space forming member 1220
forming the temperature control space SP2 where the exothermic or
endothermic reaction occurs.
[0471] The temperature control agent 1210 reacts with the liquid
reactant (refer to W2 in FIG. 45) put into the temperature control
space SP2, thereby causing the exothermic or endothermic reaction.
Here, The temperature control agent 1210 may include the liquid
reactant (refer to W2 in FIG. 45).
[0472] The temperature control agent 1210 includes the reactant
1211 exothermically or endothermically reacting with the liquid
reactant (refer to W2 in FIG. 45) and the reactant accommodating
section 1213. The reactant 1211 includes the heating element or the
heat absorption agent causing the exothermic or endothermic
reaction.
[0473] The reactant 1211 may include at least one as the heating
element among calcium oxide (CaO), calcium hydroxide (Ca(OH)2),
magnesium chloride (MgCl2), iron (Fe) and aluminum (Al). Here, the
reactant 1211 may be replaced by various materials as long as it
can exothermically react with the liquid reactant W2.
[0474] Meanwhile, the reactant 1211 may include at least one as the
heat absorption agent among ammonium nitrate (NH4NO3), sodium
acetate (CH3COONa) and (urea). Of course, the reactant 1211 may be
replaced or changed by other substances as long as it can
endothermally react with the liquid reactant W2.
[0475] The reactant accommodating section 1213 accommodates the
reactant 1211. The reactant accommodating section 1213 may be
provided as an absorption fabric to absorb or transmit the liquid
reactant W2. As necessary, the reactant accommodating section 1213
may be made of various materials that can absorb or transmit the
liquid reactant W2.
[0476] The temperature control space forming member 1220 is
opposite to the first accommodating section film 1110 of the
contents-accommodating section 1100 and forms the temperature
control space 134 for accommodating the temperature control agent
1210 therebetween.
[0477] The temperature control space forming member 1220 may be
made of a transparent synthetic resin film so that the liquid
reactant W2 and the temperature control agent 1210 to be inserted
can be checked by naked eyes. Of course, the temperature control
space forming member 1220 may be partially made of the transparent
synthetic resin film checkable by naked eyes. Of course,
checkability by naked eyes is optional, and thus an opaque film may
be used as necessary.
[0478] The upper end sealing regions SA1 of the temperature control
space forming member 1220 and the first accommodating section film
1110 may be aligned with each other and then sealed up as shown in
FIG. 44. As necessary, the upper end of the temperature control
space forming member 1220 may be positioned lower than the upper
end of the first accommodating section film 1110m and the upper end
of the temperature control space forming member 1220 may be coupled
to the first accommodating section film 1110.
[0479] The temperature control space forming member 1220 maybe
provided as the plastic film such as PP, PE, PET, etc. For example,
the temperature control space forming member 1220 may include the
plastic film where the PET film having a thickness of 12 .mu.m and
the CPP film having a thickness of 60 .mu.m are combined. Of
course, this is nothing but illustrative. Alternatively, the
plastic film may be a combination film where films of various
well-known substances are combined or a single material film.
[0480] Meanwhile, the temperature control space forming member 1220
is arranged to be lower than the upper end of the
contents-accommodating section 1110, and includes the liquid
reactant insertion portions 1230, 1240 into which the liquid
reactant (refer to W2 in FIG. 45) can be put.
[0481] The liquid reactant insertion portions 1230, 1240 includes a
first folding portion 1230 where the temperature control space
forming member 1220 is folded outward; and a first cutting portion
1240 for cutting the first folding portion 1230.
[0482] Here, the first folding portion 1230 may be folded inward as
opposed to that shown in FIG. 44. In this case, the first folding
portion 1230 may be partially exposed to the outside so that a user
can take out the inward folded first folding portion 1230 before
cutting the first folding portion 1230.
[0483] The first folding portion 1230 may protrude to have an end
being gradually inclined downward as shown in FIG. 44. Thus, it is
possible to prevent the liquid reactant remaining after the
reaction from leaking out through the cut first folding portion
1230.
[0484] The first cutting portion 1240 may include notches
respectively arranged at opposite edges of the first folding
portion 1230. As necessary, the notch may be formed at only one
side.
[0485] The first cutting portion 1240 may include a cutting groove
(not shown) extended along a cutting direction instead of the shown
notch. To prevent foreign materials from being introduced into the
temperature control space SP2 through the cutting groove (not
shown), the cutting groove (not shown) may be not a slit completely
penetrating the temperature control space forming member 1220 but a
groove where the temperature control space forming member 1220 is
relatively thin.
[0486] Meanwhile, the temperature control space forming member 1220
may further include a second folding portion 1250 to be expanded by
vapor generated by the exothermic reaction in the temperature
control space SP2. Here, the second folding portion 1250 may be
omitted as necessary.
[0487] Below, use of the pouch 1000 according to the foregoing
twenty-third exemplary embodiment will be described with reference
to FIG. 45 to FIG. 47.
[0488] As described above, the contents CA1 may be put in by a
manufacturer or may be put in the opened contents-accommodating
section 1100 of the pouch 1000 by a user. In the state that the
contents CA1 to be controlled with regard to temperature are
accommodated in the contents-accommodating section 1100, a user
cuts the first folding portion 1230 through the first cutting
portion 1240.
[0489] Thus, as shown in FIG. 45, the first folding portion 1230 is
divided into a first upper folding part 1231 and a first lower
folding part 1233. Thus, the temperature control space SP1 is
opened. The liquid reactant W2 is put in between divided first
upper and lower folding parts 1231, 1233.
[0490] As shown in FIG. 46, the put liquid reactant exothermically
or endothermically reacts with the temperature control agent 1210.
Here, if the exothermic reaction occurs, vapor is generated and the
generated vapor is discharged to the outside through the divided
first upper and first lower folding parts 1231, 1233 while
expanding the second folding portion 1250.
[0491] Here, even though an abnormal state that vapor is suddenly
and explosively generated happens during the exothermic process, it
can be damped as the second folding portion 1250 expands. Thus, it
is possible to prevent the temperature control space forming member
1220 from being torn as it cannot stand vapor pressure, and prevent
the temperature control space SP2 from being opened in other
sealing portion except the liquid reactant insertion portions 1230,
1240 and the liquid reactant W2 from flowing out.
[0492] As necessary, a user may transfer the heated or cooled
contents CA1 by the exothermic or endothermic reaction to a
separate external container A9 in order to take it in. In this
case, as shown in FIG. 47, the liquid reactant W3 remaining in the
temperature control space SP2 after the reaction is blocked by the
upper end sealing regions SA1 of the temperature control space
forming member 1220 and the first accommodating section film 1110
and does not leak out. As described above, the first folding
portions 1231, 1233 protrude being inclined downward, and thus the
first folding portions 1231, 1233 are inclined upward when the
pouch 1000 is turned upside down as shown in FIG. 47, thereby
further preventing the liquid reactant W3 from leaking out.
[0493] Here, the upper end sealing regions SA1 of the temperature
control space forming member 1220 and the first accommodating
section film 1110 are used as a liquid reactant leaking-out
preventing portion.
[0494] Meanwhile, the foregoing is described under conditions that
the liquid reactant is not accommodated in the pouch 1000, but not
limited thereto. As necessary, the liquid reactant may be
accommodated and sealed in the temperature control space SP2 of the
pouch 1000.
[0495] In more detail, as shown in FIG. 48, the liquid reactant
portion 1300 including the liquid reactant W2; and a liquid
reactant bag 1310 for packing the liquid reactant W2 may be
provided inside the temperature control space SP2.
[0496] The liquid reactant bag 1310 may include an accommodating
space portion 1313 for forming the accommodating space to
accommodate the liquid reactant W2; a liquid reactant discharging
portion 1311 through which the accommodated liquid reactant W2 can
be discharged; and a cut portion 1314 for cutting the upper end of
the liquid reactant discharging portion 1311. The liquid reactant
discharging portion 1311 may be narrower than the accommodating
space portion 1313. Thus, the liquid reactant can be easily
discharged toward a predetermined target.
[0497] The amount of liquid reactant for optimally reacting with
the temperature control agent 1210 is defined. If a general user is
allowed to put the liquid reactant into the temperature control
space SP2, the exothermic or endothermic reaction may not occur as
originally designed since a random amount of liquid reactant is
put.
[0498] Thus, as necessary, the liquid reactant portion 1300
containing the optimal amount of liquid reactant for reacting with
the temperature control agent 1210 provided in the temperature
control space SP2 may be internally provided.
[0499] The liquid reactant portion 1300 together with the
temperature control agent 1210 may be placed in the temperature
control space SP2. At this time, the temperature control space SP2
may be sealed up in the state that the liquid reactant portion 1300
and the temperature control agent 1210 are both placed.
[0500] The liquid reactant portion 1300 is not open if a user
artificially cuts the cut portion 1314, and therefore the liquid
reactant does not leak out from the liquid reactant bag 1310.
[0501] A method of using the pouch provided with both the liquid
reactant portion 1300 and the temperature control agent 1210 is as
follows. Using the first cutting portion 1240 shown in FIG. 43, the
first folding portion 1230 is cut to open the temperature control
space SP2.
[0502] From the open temperature control space SP2, the liquid
reactant bag 1310 is taken out and its cut portion 1314 is cut.
Then, the liquid reactant W2 contained in the liquid reactant bag
1310 is put into the temperature control space SP2.
[0503] Thus, the exothermic or endothermic reaction occurs in the
temperature control space SP2 so that the contents CA1 filled in
the contents-accommodating section 1110 can be heated or
cooled.
[0504] Except for taking out and putting the liquid reactant
portion 1300 containing the liquid reactant, the other using
methods are the same as the foregoing pouch using method, and thus
repetitive descriptions will be avoided.
[0505] Meanwhile, the foregoing illustrates that the liquid
reactant portion 1300 is accommodated in the temperature control
space SP2, but not limited thereto. As necessary, the liquid
reactant portion 1300 may be detachably attached to the pouch 1000
by adhesive or the like on the outer surface. Besides, the liquid
reactant portion 1300 may be coupled to the pouch 1000 in various
forms as long as it can together with the pouch 1000 be
carried.
Twenty-Fourth Exemplary Embodiment
[0506] A pouch 1000a according to the twenty-fourth exemplary
embodiment as shown in FIG. 49 and FIG. 50 includes a
contents-accommodating section 1100a; a temperature controller
1200a; a liquid reactant portion 1300; and a pouch stand 1400.
[0507] The pouch 1000a according to the twenty-fourth exemplary
embodiment is different from that of the foregoing twenty-third
exemplary embodiment in that the contents-accommodating section
1100a is formed as a single body, in that the temperature control
space SP3, SP4 and the temperature control agent 1210 are arranged
at both front and back sides with the contents-accommodating
section 1100a therebetween, and in that the pouch 1000a can stand
by itself. Here, the liquid reactant portion 1300 may be not
accommodated in the pouch 1000a as described above.
[0508] The contents-accommodating section 1100a includes a first
accommodating section film 1110a and a second accommodating section
film 1120a. The first and second accommodating section films 1110a,
1120a may be formed as a single body. That is, the
contents-accommodating section 1100a may be provided in the form of
folding one sheet of film so as to form the contents-accommodating
space SP1. The contents-accommodating section 1100a according to
the twenty-third exemplary embodiment is formed by thermally
sealing up two films of the first accommodating section film 1110
and the second accommodating section film 1120. On the other hand,
the contents-accommodating section 1100a according to the
twenty-fourth exemplary embodiment is formed as a single body.
[0509] The lower end 1130 of the contents-accommodating section
1100a is spaced apart from a standing portion 1400. Thus, the
liquid reactant to be put into the temperature controller 1200a can
flow out from the first temperature control space SP3 to the second
temperature control space SP4 through the communication space SP5
between the lower end 1130 of the contents-accommodating section
1100a and the standing portion 1400.
[0510] The temperature controller 1200a according to the
twenty-fourth exemplary embodiment includes a first temperature
control space forming member 1220 opposite to the first
accommodating section film 1110 of the contents-accommodating
section 1100 and forming the first temperature control space SP3; a
second temperature control space forming member 1260 opposite to
the second accommodating section film 1120 of the
contents-accommodating section 1100; a plurality of temperature
control agents 1210 respectively arranged in the first and second
temperature control spaces SP3, SP4; the liquid reactant insertion
portions 1230, 1240 formed in the first temperature control space
forming member 1220; and the second folding portion 1250.
[0511] As described above, the liquid reactant insertion portion
1230 includes a plurality of first folding portion 1230; and a
first cutting portion (refer to 1240 in FIG. 43) for respectively
utting the plurality of first folding portion 1230. Here, when the
plurality of first folding portions 1230 are respectively cut and
the liquid reactant cause the exothermic reaction, generated
reaction gas may discharge cold air from the first and second
temperature control space to the outside through the plurality of
first folding portions 1231, 1233 cut at opposite sides. Thus, the
contents CA1 can be quickly heated and thermal efficiency can be
improved.
[0512] The plurality of first folding portion 1230 may protrude
from the first temperature control space forming member 1220 and
the second temperature control space forming member 1260,
respectively.
[0513] As necessary, the plurality of first folding portion 1230
may be provided in only one of the first temperature control space
forming member 1220 and the second temperature control space
forming member 1260.
[0514] The plurality of first folding portion 1230 may have a
protruding end being inclined down.
[0515] Here, as described above, the second folding portion 1250
may be omitted as necessary.
[0516] The pouch 1000a according to the twenty-fourth exemplary
embodiment as shown in FIG. 43 and FIG. 44 further includes an
upper end sealing portion SA1 for sealing up the upper end portion
of the contents-accommodating section 1100a; a liquid reactant
leak-out preventing portion SA5 placed between the upper end
sealing portion SA1 and the first folding portion 1230 and
preventing the put liquid reactant from leaking outward from the
temperature control space SP3; and a second cutting portion 1010
placed between the upper end sealing portion SA1 and the liquid
reactant leak-out preventing portion SA5 and cutting the upper end
sealing portion SA1 from the contents-accommodating section 1100a
to open the contents-accommodating section 1100a.
[0517] The upper end sealing portion SA1 may be as shown in FIG. 44
sealed up with the upper end portions of the first and second
temperature control space forming members 1210, 1260 as well as the
contents-accommodating section 110.
[0518] As necessary, the upper ends of the first and second
temperature control space forming members 1210, 1260 may be placed
to be lower than the upper end of the contents-accommodating
section 1100a. The upper ends of the first and second temperature
control space forming members 1210, 1260 may be regarded as the
upper end of the liquid reactant leak-out preventing portion
SA5.
[0519] The liquid reactant leak-out preventing portion SA5 includes
the sealing portion SA5 for sealing up between the
contents-accommodating section 1100a and the first temperature
control space forming member 1220 along a transverse direction at a
position spaced apart from the first folding portion 1230 in a
longitudinal direction in order to prevent the liquid reactant from
leaking out.
[0520] The contents-accommodating section 1100a, the first and
second temperature control space forming members 1210, 1260 are
coupled by sealing up the respective left and right ends SA2, SA3
thereof.
[0521] The standing portion 1400 is arranged between the first and
second temperature control space forming members 1210, 1260 so that
the lower end portions of the first and second temperature control
space forming members 1210, 1260 can be spaced apart from each
other. Thus, it forms a lower region closed curve of the pouch
1000a according to the twenty-fourth exemplary embodiment, so that
the pouch 1000a can stand by itself without any separate
device.
[0522] In more detail, the standing portion 1400 includes a first
end SA4 sealing-coupled to the first temperature control space
forming member 1210, and a second end SA6 sealing-coupled to the
second temperature control space forming member 1260.
[0523] The process of using the pouch 1000a according to the
foregoing twenty-fourth exemplary embodiment will be described with
reference to FIG. 51. Using the first cutting portion 1240, the
first folding portion 1230 is cut.
[0524] Through the cut first folding portions 1231, 1233, the
liquid reactant portion 1300 is taken out from the first
temperature control space SP3.
[0525] The cut portion (refer to 1314 in FIG. 48) of the taken-out
liquid reactant portion 1300 is cut. Further, the liquid reactant
bag 1310 is squeezed to inject the liquid reactant W2 into the
first temperature control space SP3 through the cut first folding
portions 1231, 1233.
[0526] The injected liquid reactant W2 causes the exothermic or
endothermic reaction in the first temperature control space SP3.
Meanwhile, the unreaded and remaining liquid reactant W2 is
discharged to the second temperature control space SP4 through the
communication space SP5. The discharged liquid reactant
exothermically or endothermically reacts again with the temperature
control agent 1210 provided in the second temperature control space
SP4.
[0527] Thus, the contents CA1 accommodated in the
contents-accommodating section 1100a can be heated or cooled.
[0528] To take out or take in the heated or cooled contents CA1,
the second cutting portion (refer to 1010 in FIG. 49) is cut to
open the contents-accommodating section 1100a.
[0529] At this time, if the pouch 1000a is turned upside down in
order to transfer the contents CA1 accommodated in the
contents-accommodating section 1100a to a separate external
container (refer to A in FIG. 47), the liquid reactant W3 remaining
in the first temperature control space SP3 after the reaction is
blocked by the liquid reactant leak-out preventing portion SA5 and
prevented from leaking out.
[0530] Although a few exemplary embodiments have been shown and
described, it will be appreciated by those skilled in the art that
changes may be made in these exemplary embodiments without
departing from the principles and spirit of the invention, the
scope of which is defined in the appended claims and their
equivalents.
