Description
TECHNICAL FIELD
[0001] The present invention relates to a vertical pouch.
BACKGROUND
[0002] To conveniently heat a content without any separate cookware
in field or military training, a pouch of a disposable package has
been released in the market. A conventional pouch includes an
edible content, a content container, a heating element for heating
the content, and a reaction liquid inlet for injecting a reaction
liquid of reacting with the heating element from the exterior.
[0003] The conventional pouch is inconvenient as follows. A user
has to vertically hold the pouch to prevent the reaction liquid
from flowing out while the reaction liquid is injected into the
reaction liquid inlet and makes the heating element generate heat.
The user cannot lay the pouch down, but has to hold the pouch with
one hand while eating the content with the other hand.
[0004] Further, it is uncomfortable for a user to continuously hold
the pouch since heat from exothermic reaction is transferred to the
user's hand while the user holds the pouch.
[0005] In addition, if the heating elements are placed at either
side of the content container in the middle of the pouch, it is
burdensome for a user to inject the reaction liquid into both
sides.
[0006] Generally, left and right heating element containers are
arranged to surround the content container in the middle, and the
content container in the middle is heated by heat generated by the
reaction of the heating elements. In this case, problems of heat
loss and inconvenience arise since a considerable amount of heat
leaks through the outer sheets of the heating element
containers.
SUMMARY
[0007] An aspect of the invention is to provide a vertical pouch
which can be stably stood up.
[0008] Another aspect of the invention is to provide a vertical
pouch which can minimize heat transferred to a user's body or the
outside.
[0009] Still another aspect of the invention is to provide a
vertical pouch in which heating elements at either side are all
reacted by injecting a reaction liquid into a heating element
container at one side.
[0010] The foregoing and/or other aspects of the present invention
are achieved by providing a vertical pouch including: a heating
element to react with a reaction liquid and cause an exothermic
reaction; a first pack configured to form a space for containing
the heating element between a first sheet and a second sheet; a
second pack configured to form a space for containing the heating
element between a third sheet and a fourth sheet; a content
container comprising the second sheet of the first pack, the third
sheet of the second pack, and a bottom connecting lower portions of
the second and third sheets and folded upward and downward; and a
reaction liquid passage configured to make the first pack
communicate with the second pack.
[0011] The reaction liquid passage may be formed by penetrating an
adhered portion where the second sheet and the third sheet are
adhered, or by bending and adhering edge portions of the second and
third sheets from edges of the first and fourth sheets.
[0012] The reaction liquid passage may be formed higher than a fold
when the bottom is folded upward.
[0013] The first sheet, the second sheet, the third sheet and the
fourth sheet may include a plurality of sheet members, an air-gap
may be formed between the sheet members, and at least one of the
sheet members may include an insulating sheet member.
[0014] At least one of the first sheet and the fourth sheet further
may include a reaction liquid inlet through which a reaction liquid
can be injected, and the first pack and the second pack may further
include a reaction liquid pack to accommodate a reaction
liquid.
[0015] According to the vertical pouch configured as described
above has at least one of the following effects.
[0016] First, the pouch is minimized in volume while being kept,
and is stably stood while being used so that a user can easily eat
a content.
[0017] Second, it is possible to minimize heat transferred to a
user's body or the outside when the exothermic reaction occurs.
[0018] Third, the heating elements at both sides are all reacted by
injecting the reaction liquid into the heating element container at
only one side.

DETAILED DESCRIPTION
[0026] Below, embodiments of the present invention will be
described with reference to accompanying drawings.

first embodiment of the present invention, FIG. 2 is a sectional
view of the pouch 100 according to the first embodiment of the
present invention, FIG. 3 is an enlarged sectional view of a
reaction liquid passage 170 according to the first embodiment of
the present invention, FIG. 4 is a perspective view of a pouch 200
according to a second embodiment of the present invention, FIG. 5
is an enlarged sectional view of a reaction liquid passage 270 in
the pouch 200 according to the second embodiment of the present
invention, FIG. 6 is a sectional view showing that a first sheet
310 and a fourth sheet 340 of a pouch 300 include air-gaps 318 and
348 according to a third embodiment of the present invention, and
FIG. 7 is a perspective view of a pouch 400 with a reaction liquid
pack 480 according to a fourth embodiment of the present
invention.
[0028] As shown in FIGS. 1 and 2, the vertical pouch 100 according
to the first embodiment of the present invention includes a first
pack 101, a second pack 102, and a content container 160 formed
between the first pack 101 and the second pack 102.
[0029] In the first pack 101, a first sheet 110 and a second sheet
120 are adhered to each other only at its ending part so as to form
a space in the middle of the first sheet 100 and the second sheet
120. A heating element 10 is accommodated in the middle space
formed by adhering the first sheet 110 and the second sheet
120.
[0030] The heating element 10 may include a liquid or solid
material that reacts with a reaction liquid and causes an
exothermic reaction. Preferably, the sold material may be used to
prevent the heating element 10 from leaking out. The solid heating
element 10 may include one or more among calcium oxide (CaO),
calcium hydroxide (Ca(OH).sub.2), magnesium chloride (MgCl.sub.2),
iron (Fe) and aluminum (Al).
[0031] The adhering process may be achieved by a method of piling
up the first sheet 110, the heating element 10 and the second sheet
120 in sequence and adhering four edges thereof, or a method of
first adhering the edges of the first sheet 110 and the second
sheet 120 in the form of `U` except the upper edge and then sealing
up the upper edge after inserting the heating element 10 through
the upper edge.
[0032] The second pack 102 may be formed by adhering edges of a
third sheet 130 and a fourth sheet 140, and accommodates the
heating element 10 in a space formed by adhering the third sheet
130 and the fourth sheet 140 like the first pack 101. Such adhesion
between the sheets 110, 120, 130 and 140 may be achieved by heat
sealing, high frequency sealing or the like.
[0033] As shown in FIG. 2, the first sheet 110 forming an outer
surface of the pouch 100 includes a plurality of sheet members 112,
114 and 116. Like the first sheet 110, the fourth sheet 140 also
includes a plurality of sheet members 142, 144 and 146.
[0034] When heat is generated inside the pouch 100, heat is
transferred to a user's body being in contact with the pouch 100 or
to the outside. To minimize the transfer of the heat, the first
sheet 110 and the fourth sheet 140 include a plurality of layers.
As the first sheet 110 and the fourth sheet 140 are formed by the
plurality of layers, it is also possible to protect the heating
element 10 or the content from external shock. If a reaction liquid
bag is enveloped together with the heating element 10, the
plurality of layers may prevent the reaction liquid bag from being
damaged by external shock and wastefully react with the heating
element 10.
[0035] Sheet members 112 and 142 provided in the outmost surface of
the first sheet 110 and the fourth sheet 140 are comprised of by
insulating sheet members so as to further minimize heat transfer to
a user. As necessary, the insulating sheet member may be applied to
not only the outmost sheet members 112 and 142 but also the other
sheet members 114, 116, 144 and 146, and a plurality of insulating
sheet members may be used for the first sheet 110 and the fourth
sheet 140. The insulating sheet member may include polyurethane,
polystyrene, calcium silicate or the like.
[0036] Like the first sheet 110 and the fourth sheet 140, the
second sheet 120 of the first pack 101 and the third sheet 130 of
the second pack 102 may include a plurality of sheet members. For
example, the second sheet 120 may include two sheet members 122 and
124 and an air-gap 126 formed between the plurality of sheet
members 122 and 124. Like the second sheet 120, the third sheet 130
may include two sheet members 132 and 134 and an air-gap 136
between the sheet members 132 and 134.
[0037] If the second sheet 120 and the third sheet 130 are each
comprised of a single sheet, the heating element 10, reaction gas
generated by reaction between the reaction liquid and the heating
element 10, or the like may flow in the content container 160 when
a minute pinhole is generated in the second sheet 120 and the third
sheet 130. In order to prevent this, the second sheet 120 and the
third sheet 130 are configured to the plurality of sheet members
122, 124, 132 and 134, respectively.
[0038] The air-gaps 126 and 136 serve to protect the content
accommodated in the content container 160 from being damaged or
deformed by external shock. The air-gap 126 is formed by adhering
edges of the sheet members 122 and 124 to form a space in the
middle. This manner is also applied to the air-gap 136 of the third
sheet 130.
[0039] The second sheet 120 and the third sheet 130 are adhered to
each other at opposite longitudinal end portions. The bottom 150 is
adhered to the lower portions of the second sheet 120 and the third
sheet 130. The bottom 150 includes a fold 152 to be folded upward
or downward in the pouch 100.
[0040] The bottom 150 is folded usually, and is pulled and
stretched out in directions of the first sheet 110 and the fourth
sheet 140 and laid down so that the pouch 100 can be stood. When
the bottom 150 is folded, the pouch 100 is decreased in volume to
be easily kept. When the bottom 150 is stretched out, the pouch 100
can be stood to be convenient for a user to eat the content in the
pouch 100. Further, if the pouch 100 is stood during the exothermic
reaction of the heating element 10, a user is free from getting
burned since the user does not have to hold the pouch 100 with the
user's hand.
[0041] Thus, the content container 160 formed by the second sheet
120, the third sheet 130 and the bottom 150 is provided inside the
pouch 100. The content container 160 may be filled with the content
such as food, and the content such as food is heated by the heating
element 10. If food is directly filled in the content container
160, the second sheet 120, the third sheet 130 and the bottom 150
may be made of materials harmless to humans.
[0042] The first pack 101 and the second pack 102 include a
reaction liquid passage 170 through which they communicate with
each other. As shown in the enlarged sectional view of FIG. 3, the
reaction liquid passage 170 is formed to make the first pack 101
and the second pack 102 communicate with each other so that the
reaction liquid introduced into the first pack 101 can flow to the
second pack 102. Alternatively, the reaction liquid introduced into
the second pack 102 may flow to the first pack 101. According to
the first embodiment, the reaction liquid passage 170 is formed by
penetrating an adhered portion where the second sheet 120 and the
third sheet 130 are partially adhered. The adhered portion has to
be penetrated so that the reaction liquid can flow only to the
second pack 102 without leaking to the content container 160.
[0043] The reaction liquid passage 160 may be formed higher than
the fold when the bottom 150 is folded upward. If the reaction
liquid passage 160 is placed below the fold 152, the bottom 150 is
not completely stretched out. The pouch 100 can be stood only when
the bottom 150 has to be stretched out as much as a predetermined
distance. However, if the reaction liquid passage 170 is placed
below the fold 152, i.e. if the second sheet 120 and the third
sheet 130 are adhered close by the bottom 150, this interferes with
stretching out the bottom 150. Thus, the reaction liquid passage
160 is preferably formed above the fold 152 so as not to interfere
with the bottom 150 that is largely changed in position.
[0044] At least one of the first sheet 110 and the fourth sheet 140
may include a reaction liquid inlet 180 through which the reaction
liquid can be injected. If the reaction liquid inlet 180 is formed
in the first sheet 110, the reaction liquid is injected into the
first pack 101. If the reaction liquid inlet 180 is formed in the
fourth sheet 140, the reaction liquid is injected into the second
pack 102. Then, the injected reaction liquid moves to the other
pack via the reaction liquid passage 170. Since the reaction liquid
is injected through the reaction liquid inlet 180, the reaction
liquid passage 170 is preferably placed below the reaction liquid
inlet 180 so that the reaction liquid can flow to the other pack.
Alternatively, the reaction liquid inlet 180 may be formed in both
the first sheet 110 and the fourth sheet 140 so that the reaction
liquid can be injected at both sides.
[0045] As shown in FIGS. 4 to 5, a vertical pouch 200 according to
a second embodiment of the present invention includes a first pack
(not shown), a second pack (not shown) and a bottom 250 formed
between the first and second packs. A first sheet 210 and a fourth
sheet 240 include a plurality of sheet members 212, 214, 216, 242,
244 and 246, and the outmost sheet members 212 and 242 may be an
insulating sheet member. Further, a reaction liquid inlet 280 is
formed in the first sheet 210, the fourth sheet 240 or both the
first sheet 210 and the fourth sheet 240. Likewise, a second sheet
220 and a third sheet 230 include a plurality of sheet members 222,
224, 232 and 234.
[0046] The elements of the second embodiment are similar to those
of the first embodiment. However, the first and second embodiments
are different in shape of a reaction liquid passage 270 formed
between a second sheet 220 and a third sheet 230.
[0047] As shown in FIG. 4, the portion of the second sheet 220 and
the third sheet 230 are grooved in the form of ``, and this portion
is differentiated in that only the second sheet 220 and the third
sheet 230 are adhered to each other. The first sheet 210, the
second sheet 220, the third sheet 230 and the fourth sheet 240 are
all adhered at end portions in a transverse direction except the
portion in the form of `U`. But the second sheet 220 is adhered to
the third sheet 230 and the first sheet 210 is adhered to the
fourth sheet 240 at the portion grooved in the form of ``as shown
in FIG. 4 so that the portion formed by the adhesion can function
as a reaction liquid passage 270 through which the reaction liquid
passes. Alternatively, the reaction liquid passage 270 may vary in
area, shape and position.
[0048] The reaction liquid passage 270 shown in FIG. 5 serves to
make the reaction liquid flow from the first pack 201 to the second
pack 202 or from the second pack 202 to the first pack 201 like
that of the first embodiment. On the contrary to the first
embodiment, the reaction liquid passage 270 is formed in the end
portion of the pouch 200 so that the content can be filled in the
pouch 200 without being interfered with the reaction liquid passage
270. The reaction liquid passage 170 of the first embodiment and
the reaction liquid passage 270 of the second embodiment are
similar in their function and shape, but different in the
manufacturing process.
[0049] According to the third embodiment, the pouch 300 includes a
first pack 301, a second pack 302, and a bottom 350 formed between
the first pack 301 and the second pack 302, and includes a content
container 360 in the middle. The first sheet 310 and the fourth
sheet 340 include a plurality of sheet members 312, 314, 316, 342,
344 and 346, and the outmost sheet members 312 and 342 may be an
insulating sheet member. Further, a reaction liquid inlet 280 may
be formed in the first sheet 310, the fourth sheet 340 or both the
first sheet 310 and the fourth sheet 340.
[0050] The bottom 350 includes a fold 352 so that the bottom 350
can be folded upward.
[0051] In addition, the second sheet 320 and the third sheet 330
include a plurality of sheet members 322, 324, 332 and 334.
[0052] The elements of the third embodiment are similar to those of
the second embodiment, but different in some portions of the first
sheet 310 and the fourth sheet 340.
[0053] As shown in FIG. 6, the first sheet 310 and the fourth sheet
340 include the plurality of sheet members 312, 314, 316, 342, 344
and 346 in order to minimize heat transferred to a user's body. In
particular, the outmost sheet members 312 and 342 are made of
insulating sheet members to further minimize heat transfer.
[0054] In addition, an air-gap 318 is formed in between the outmost
sheet member 312 and the second sheet member 314 of the first sheet
310, so that the heat transfer can be more minimized than that of
when only the plurality of sheet members 312, 314 and 316
constitutes the first sheet 310. Alternatively, the air-gap 318 may
be formed in between the second sheet member 314 and the third
sheet member 316. Like the first sheet 310, an air-gap 348 may be
added in between the sheet members 342, 344 and 346 of the fourth
sheet 340 to minimize heat transferred to a user.
[0055] The air-gaps 318 and 348 may use an air cap which is
generally used for protecting a product and in which a plurality of
air bubbles are arranged. Besides, the sheet members 312, 314, 316,
342, 344 and 346 of the first sheet 310 and the fourth sheet 340
may be adhered in the form of lattice at edges and insides, and air
may be injected in the lattices not adhered between the sheet
members 312, 314, 316, 342, 344 and 346.
[0056] According to the fourth embodiment, the pouch 400 includes
the first pack 101, the second pack 102, and a bottom 450 adhered
to the lower portions of the first pack 101 and the second pack 102
and forming the content container 160.
[0057] The first pack 101 includes the first sheet 110 and the
second sheet 120, and the second pack 102 is formed by adhering
only the edges of the third sheet 130 and the fourth sheet 140.
[0058] The heating element 10 is added in between the first pack
101 and the second pack 102.
[0059] The first sheet 110 and the fourth sheet 140 include the
plurality of sheet members 112, 114, 116, 142, 144 and 146, and the
outmost sheets 112 and 142 may be an insulating sheet member.
Further, the second sheet 120 and the third sheet 130 also include
the plurality of sheet members 122, 124, 132 and 134.
[0060] These elements are the same as those of the first
embodiment, but the fourth embodiment does not include the reaction
liquid inlet 180.
[0061] As shown in FIG. 7, the pouch 400 does not include the
reaction liquid inlet 180 but instead includes a reaction liquid
pack 480 placed in one space, where the heating element 10 is
placed, between the first sheet 110 and the second sheet 120 or
between the third sheet 130 and the fourth sheet 140.
[0062] In the case where heat generation is caused from the outside
of the pouch, it may be impossible to get the reaction liquid, i.e.
water. In this case, the pouch 400 provided with the reaction
liquid pack 480 is used so that the pouch 400 can be easily
heated.
[0063] The reaction liquid pack 480 may be formed to be torn open
by predetermined force from the exterior so that the heating
element 10 and the reaction liquid can meet, or the reaction liquid
pack 480 may have a tearing member and be torn by the tearing
member so that the reaction liquid can flow from the reaction
liquid pack 480.
[0064] According to the foregoing embodiments, the vertical pouch
100, 200, 300, 400 can be vertically laid on a table or the like by
stretching out the folded bottom 150, 250, 350, 450 if it is
inconvenient for a user to hold the pouch 100, 200, 300, 400 with
one hand and take the content out with the other hand, thereby
allowing him/her to easily take the content.
[0065] Further, the first sheet 110, 210, 310 and the fourth sheet
140, 240, 340 include the plurality of layers so that heat
transferred to a user's body can be minimized when the exothermic
reaction occurs, and the insulating sheet member included in the
plurality of layers include the air-gap 318, 348 so that a user can
hold the pouch 100, 200, 300, 400 without inconvenience.
[0066] In addition, the second sheet 120, 220, 320 and the third
sheet 130, 230, 330 include the plurality of layers so that the
heating element 10, the reaction liquid or reaction gas caused by
the reaction between them cannot be introduced into the content
container 160.
[0067] Furthermore, if the heating elements 10 are separately
provided at both sides of the pouch 100, 200, 300, 400, to the
reaction liquid has to be conventionally put into both sides.
However, the pouch 100, 200, 300, 400 according to the present
invention includes the reaction liquid passage 170, 270 so that the
reaction liquid injected into one of the two sides can be enough to
make all the heating elements 10 generate heat. Accordingly, it is
convenient for a user.
