Description
TECHNICAL FIELD
[0001] The present invention relates to a container, such as a pet
bottle, provided with a mouth portion, a shoulder portion, a body
portion and a bottom portion, and, particularly, to a container of
which the shoulder portion can be easily gripped.
BACKGROUND ART
[0002] A plastic bottle container such as a pet bottle is suitable
to mass production because it can be easily molded and also, has
such excellent characteristics that it has high mechanical strength
and a light weight. Therefore, it is utilized as a container for
filling various liquids in a wide field. Particularly, this
container is currently used in large numbers as beverage containers
for various drinks and mineral water.
[0003] As to the capacity of the bottle container, there are many
types in response to requests in the market. As bottle containers
having a large capacity, for example, those having about 2 litters
or more are used. As to the shape of the bottle container,
containers having a cross-section of rectangular or square form
have been conventionally adopted in consideration of storage
easiness in a refrigerator and handy-carrying easiness.
[0004] In the meantime, when a liquid is filled in a bottle
container having a large capacity, the weight of the container is
increased considerably due to the weight of the liquid. For this,
when the bottle container is lifted in the case of, for example,
pouring a content liquid, it is necessary to grip the bottle
container by considerable strong force. If the gripping force is
larger like this, there is the case where the container is deformed
and the bottle container is slipped on the hand gripping the bottle
container, posing the problem that it is difficult to lift the
container.
[0005] To deal such a problem, there is a proposal of a bottle
container improved in gripping ability by forming a grip concave
portion (grip portion) at the body portion of the bottle container
to hang fingers on the concave portion when gripping the bottle
container with one hand (see, for example, the grip concave portion
of a bottle container according to an embodiment of the present
invention).
[0006] Also, there is a proposal of a bottle container having a
grip portion at the position above the body portion (see, for
example, Patent Documents 1 and 2).
[0007] In the bottle container described in, for example, Patent
Document 1, a flat portion is formed as the grip portion at the
upper portion of the bottle container.
[0008] Also, in the bottle container described in Patent Document
2, the neck portion connecting the mouth portion with the shoulder
portion is formed as the grip portion. [0009] [Patent Document 1]

DISCLOSURE OF THE INVENTION
Problem to be Solved by the Invention
[0011] As shown in Patent Documents 1 and 2, the bottle container
having a grip portion at the position above the body portion has
the advantage that the grip portion is not concealed even in the
situation where the container is packed in a casing or stored in a
refrigerator and therefore, the container is easily taken out of
the box or refrigerator.
[0012] However, since a wide vertical surface is formed as the grip
portion in each of the bottle containers described in Patent
Document 1 and 2, there is the problem that the container is
reduced in capacity remarkably compared to a bottle container
having the same height in dimension.
[0013] Also, the bottle container described in Patent Document 1
has the problem that its shape and production method are specific
and therefore, it is not only limited in its application but also,
is produced at high costs.
[0014] The present invention has been made in view of the above
situation and it is an object of the present invention to provide a
container which not only is easily taken out of a casing or a
refrigerator but also makes it possible to avoid a remarkable
reduction in capacity and cost up.
Means for Solving the Problem
[0015] In order to attain the above object, the container of the
present invention includes a mouth portion, a shoulder portion
extending downward from the lower end of the mouth portion, a
rectangular body portion extending downward from the lower end of
the shoulder portion and a bottom portion positioned at the lower
end of the body portion, wherein a finger hanging concave portion
which serves as a finger grip when lifting the container, is formed
on at least a pair of surfaces opposite to each other in the
shoulder portion.
[0016] Such a structure ensures that the container can be lifted
with ease by gripping the finger hanging concave portion formed in
the shoulder portion. Because the finger hanging concave portion is
not concealed even in the situation where the container is packed
in a casing or stored in a refrigerator and therefore, the
container is easily taken out of the box or refrigerator. Also,
since the finger hanging concave portion is not formed as a special
vertical plane but formed by utilizing the shoulder portion and it
is therefore possible to avoid the disorders including a remarkable
reduction in the capacity of the container and a cost-up
problem.
[0017] Also, the container of the present invention preferably has
a structure in which the horizontal distance between the upper ends
of the pair of finger hanging concave portions is 55 to 90 mm.
[0018] Such a structure ensures a proper distance between the grip
fingers when gripping the pair of finger hanging concave portions,
which can improve gripping ability.
[0019] In the container of the present invention, the vertical
distance from the upper end of the finger hanging concave portion
to the upper end of the mouth portion is preferably 35 to 80
mm.
[0020] Such a structure makes it easy to grip the pair of finger
hanging concave portions and it is therefore easy to lift the
container.
[0021] Also, in the container of the present invention, the depth
of the finger hanging concave portion is preferably 3 to 15 mm.
[0022] This structure secures a depth easy for hanging fingers on
the finger hanging concave portion and therefore, the reliability
of the finger hanging concave portion on finger hanging is
improved.
[0023] Also, in the container of the present invention, the
vertical width of the finger hanging concave portion is preferably
50 mm or less and more preferably 15 to 40 mm.
[0024] Because a vertical width sufficiently enough for fingers is
secured in the finger hanging concave portion, it is easy to hang
fingers on the finger hanging concave portion.
[0025] Also, in the container of the present invention, the lateral
width of the finger hanging concave portion is preferably 90 mm or
less and more preferably 15 to 70 mm.
[0026] If the container has such a structure, plural fingers can be
hung on the finger hanging concave portion, it is much easy to lift
the container.
[0027] Also, in the container of the present invention, the surface
on which the finger hanging concave portion is to be formed in the
shoulder portion preferably has an inclination of -10 to 30.degree.
with respect to the vertical axis.
[0028] When the container is made to have such a structure, the
finger hanging concave portion is easily gripped from the above and
it is therefore easier to lift the container.
[0029] Also, in the container of the present invention, the
inclination of the side wall surface to be formed on the mouth
portion side in the finger hanging concave portion is preferably 5
to 80.degree. with respect to the horizontal axis.
[0030] In such a structure, an angle at which fingers are easily
hung on the side wall surface of the finger hanging concave portion
is secured, which improves the reliability of the finger hanging
concave portion on finger hanging.
[0031] Also, the container of the present invention may have a
structure in which the above finger hanging concave portion has its
apex on the mouth portion side and a first fold line is formed on
the surface positioned between the finger hanging concave portion
and the mouth portion such that it is positioned on the line
crossing the above apex.
[0032] This structure makes it easy to crush the shoulder portion
with the intention of reducing the volume of the bottle container
when the container is treated as waste after used. Particularly,
because the fold line is formed such that it is positioned on the
line crossing the apex of the mouth portion side of the finger
hanging concave portion, stress tends to be concentrated on the
fold line, so that the shoulder portion is easily bent along the
fold line when it is crushed.
[0033] Also, the container of the present invention may have a
structure in which the finger hanging concave portion is provided
with angular portions positioned on each of the left and right
sides thereof and a second fold line extending laterally from each
of the vicinity of the angular portions is formed.
[0034] In such a structure, the shoulder portion is crushed while
bent along both the first and second fold lines and thus the
shoulder portion is crushed more easily.
[0035] Also, the container of the present invention may have a
structure in which a finger receiving concave portion having a
convex curvature formed toward the inside of the container is
formed on the bottom side of the finger hanging concave
portion.
[0036] Such a structure makes easy to grip the finger hanging
concave portion, with the result that the bottle container can be
easily lifted.
[0037] Also, the container of the present invention preferably has
a structure in which a second finger hanging concave portion
serving as finger grip when the content is extracted from the mouth
portion by tilting the container is formed on at least a pair of
surfaces opposite to each other at the lower end of the above body
portion.
[0038] With such a structure, the tilted container can be supported
stably by gripping the second finger hanging concave portion formed
at the lower end portion of the body portion when the content is
extracted from the mouth portion by tilting it.
[0039] Also, the container of the present invention may have a
structure in which the second finger hanging concave portion is
provided with angular portions positioned on each of the left and
right sides thereof and a third fold line extending laterally from
each of the vicinity of the angular portions is formed.
[0040] In such a structure, the lower end portion of the body
portion can be crushed while bent along the third fold line.
EFFECT OF THE INVENTION
[0041] According to the present invention, as mentioned above, the
container can be easily lifted by gripping the finger hanging
concave portion formed in the shoulder portion. Because the finger
hanging concave portion is not concealed even in the situation
where the container is packed in a casing or stored in a
refrigerator and therefore, the container is easily taken out of
the box or refrigerator. Also, since the finger hanging concave
portion is not formed as a special vertical plane but formed by
utilizing the shoulder portion and it is therefore possible to
avoid the disorders including a remarkable reduction in the
capacity of the container and a cost-up problem.

BEST MODE FOR CARRYING OUT THE INVENTION
[0078] An embodiment applied to a plastic bottle container will be
explained as an example of the container of the present
invention.
[0079] As the resin constituting the bottle container, an optional
one may be used insofar as it is a thermoplastic resin which can be
processed by stretching blow molding and thermally
crystallized.
[0080] Specifically, thermoplastic polyesters such as a
polyethylene terephthalate, polybutylene terephthalate,
polyethylene naphthalate, polycarbonate, polyarylate, polylactic
acid or copolymers of these compounds, resins of these material and
blended materials obtained by blending these resins with other
resins are preferable. Particularly, ethylene terephthalate type
thermoplastic polyesters such as a polyethylene terephthalate are
preferably used.
[0081] An acrylonitrile resin, polypropylene, propylene/ethylene
copolymer, polyethylene and the like may be also used.
[0082] These resins may be compounded with various additives such
as colorants, ultraviolet absorber, releasing agent, lubricant,
nucleic agent, antioxidant and antistatic agent to the extent that
the qualities of the molded product are not impaired.
[0083] The ethylene terephthalate type thermoplastic polyester
constituting the bottle container is those in which a large neck
portion, generally 70 mol % or more, of the ester repeat units are
occupied by ethylene terephthalate units and which preferably have
a glass transition temperature (Tg) range from 50 to 90.degree. C.
and a melting point (Tm) range from 200 to 275.degree. C.
[0084] As the ethylene terephthalate type thermoplastic polyester,
a polyethylene terephthalate (PET) is especially preferable in view
of, for example, pressure resistance, heat resistance and heat and
pressure resistance. A copolymer polyester containing, besides an
ethylene terephthalate unit, a small amount of an ester unit
consisting of a dibasic acid such as isophthalic acid and
naphthalene dicarboxylic acid and a diol such as propylene glycol
may also be used.
[0085] Also, the bottle container of this embodiment is constituted
of a single (one layer) thermoplastic polyester layer and besides
such a case, it may be constituted of two or more thermoplastic
polyester layers.
[0086] Moreover, the bottle container of this embodiment may be
provided with an intermediate layer sealed in between an inner
layer and an outer layer constituted of two or more thermoplastic
polyester layers. A barrier layer and an oxygen absorbing layer may
be formed as the intermediate layers.
[0087] The provision of the barrier layer and oxygen absorbing
layer can limit the transmission of oxygen to the bottle container
from the outside to thereby prevent the content in the bottle
container from being denatured by external oxygen.
[0088] Here, as the oxygen absorbing layer, an optional one may be
used insofar as it absorbs oxygen to prevent the transmission of
oxygen. It is however preferable to use a combination of an
oxidizable organic component and a transition metal catalyst or a
combination of a gas barrier resin which is not substantially
oxidized, an oxidizable organic component and a transition metal
catalyst.
FIRST EMBODIMENT
[0089] Next, a bottle container according to a first embodiment of
the present invention will be explained with reference to FIGS. 1
to 5.
[0090] FIG. 1 is a front view of the bottle container according to
the first embodiment of the present invention. FIG. 2 is a side
view of the bottle container according to the first embodiment of
the present invention. FIG. 3 is a sectional view along the line
X-X showing the bottle container according to the first embodiment
of the present invention. FIG. 4(A) is a plan view showing the
upper portion of the bottle container according to the first
embodiment of the present invention, FIG. 4 (B) is a front view
showing the upper portion of the bottle container according to the
first embodiment of the present invention and FIG. 4(C) is a side
view showing the upper portion of the bottle container according to
the first embodiment of the present invention. FIG. 5(A) is a front
view showing the lower portion of the bottle container according to
the first embodiment of the present invention and FIG. 5(B) is a
side view showing the lower portion of the bottle container
according to the first embodiment of the present invention.
[0091] A bottle container 1 shown in these figures is a plastic
bottle container formed by processing a preform made of the
aforementioned thermoplastic resin by biaxial stretching blow
molding and is provided with a mouth portion 2, a shoulder portion
3, a body portion 4 and a bottom portion 5.
[0092] The mouth portion 2 is a portion that serves as a mouth from
which the content is taken out and is opened and closed by a cap
(not shown) engaged with the screw thread in the periphery
thereof.
[0093] The shoulder portion 3 is a portion having an almost pyramid
form extending downward from the mouth portion 2.
[0094] The bottom portion 5 is a portion extending inward from the
lower end of the body portion 4, and functions as the bottom wall
of the bottle container 1 and also as a foot portion enabling the
bottle container 1 to stand on its own bottom.
[0095] The body portion 4 is a portion having an almost quadratic
cylinder form extending downward from the lower end of the shoulder
portion 3. The sectional shape of the body portion 4 is designed to
be almost rectangular wherein the short side L1 is preferably
designed to have a length of 110 mm or less. With this structure,
the bottle container 1 is well received in a refrigerator and the
bottle container 1 can be gripped by one hand even if the bottle
container is one having a capacity as large as 2000 to 3000 ml or
more.
[0096] The body portion 4 may be designed to have a cross-section
of an almost square sectional shape. In this case, if the length of
one side of the square is designed to be 110 mm or less, good
receptivity in a refrigerator and handling characteristics can be
secured.
[0097] A waist portion 6 tighten along the peripheral direction is
formed on the center portion in the vertical direction of the body
portion 4. This waist portion 6 functions as a reinforcing portion
imparting necessary strength to the body portion 4.
[0098] Also, in this embodiment, a grip concave portion 7 is formed
on at least a pair of surfaces opposite to each other in the body
portion 4, the grip concave portion 7 serving as finger grip when
the bottle container 1 is carried by one hand to enable easy
handling. In the case where the lateral sectional shape of the body
portion 4 is almost rectangular, the grip concave portion 7 is
preferably formed on the longitudinal side of the rectangle. Also,
an anti-slipping portion 8 may be formed on the bottom surface and
side wall surface of the grip concave portion 7 by forming
projections, convex ribs, grooves or steps.
[0099] However, when the bottle container 1 is packed in a casing
or stored in a refrigerator, the grip concave portion 7 formed on
the body portion 4 is concealed by adjacent bottle containers 1 and
other stored materials and there is therefore the possibility that
the grip concave portion 7 cannot be gripped when the bottle
container 1 is taken out.
[0100] In the bottle container 1 according to this embodiment of
the present invention, as shown in FIGS. 1 to 4, the finger hanging
concave portion 9 serving as finger grip when the bottle container
1 is lifted is formed on at least one pair of surfaces opposite to
each other in the shoulder portion 3. With such a structure, the
bottle container 1 can be lifted easily by gripping the finger
hanging concave portion 9 formed on the shoulder portion 3. Because
the finger hanging concave portion 9 is not concealed even in the
situation where the container is packed in a casing or stored in a
refrigerator and therefore, the bottle container 1 is easily taken
out of the box or refrigerator. Also, since the finger hanging
concave portion 9 is not formed as a special vertical plane but
formed by utilizing the shoulder portion 3 and it is therefore
possible to avoid the disorders including a remarkable reduction in
the capacity of the bottle container 1 and a cost-up problem.
[0101] Though no particular limitation is imposed on the capacity
of the bottle container 1 formed with the finger hanging concave
portion 9, the effect of the present invention is produced
significantly when applied to a bottle container 1 having a
capacity of 900 ml or more.
[0102] Also, when the sectional shape of the shoulder portion 3
(body portion 4) is almost rectangular, the finger hanging concave
portion 9 is preferably formed on the longitudinal side of the
rectangle. With this structure, the pair of finger hanging concave
portions 9 can be gripped by one hand even in the case of a large
capacity container.
[0103] Specifically, the lateral distance L2 between the upper ends
of the pair of finger hanging concave portions 9 is preferably
designed to be 55 to 90 mm. It is thereby possible to improve
gripping ability because a proper distance is secured between
fingers gripping the container when the pair of the finger hanging
concave portions 9 are gripped.
[0104] Also, the vertical distance L3 from the upper end of the
finger grip concave portion 9 to the upper end of the mouth portion
2 is preferably designed to be 35 to 80 mm. Such a structure makes
it easy to lift the bottle container 1 because the pair of the
finger hanging concave portions 9 can be gripped with ease.
[0105] The depth D1 of the finger hanging concave portion 9 is
preferably 3 to 15 mm. Such a structure brings about the situation
where a depth allowing fingers to be easily hung is secured in the
finger hanging concave portion 9 and the certainty of the finger
hanging concave portion 9 about finger hanging is therefore
improved.
[0106] Also, the maximum vertical width L4 of the finger hanging
concave portion 9 is designed to be preferably 50 mm or less and
more preferably 15 to 40 mm. With this structure, a vertical width
large enough for the fingers is secured and therefore, it is easy
to hang fingers on the finger hanging concave portion 9.
[0107] Also, the maximum lateral width L5 of the finger hanging
concave portion 9 is designed to be preferably 90 mm or less and
more preferably 15 to 70 mm. This ensures that plural fingers can
be hung on the finger hanging concave portion 9 and it is therefore
easy to lift the bottle container 1.
[0108] Also, the ratio L5/L6 of the maximum lateral width L5 of the
finger hanging concave portion 9 to the lateral width (longitudinal
side) L6 of the body portion 4 is preferably 0.7 or less and more
preferably 0.25 to 0.6. This ensures that because the size of the
finger hanging concave portion 9 is allowed to accord with the size
of the bottle container 1, not only the gripping ability of the
finger hanging concave portion 9 is improved but also a
deterioration in the appearance of the bottle container 1 can be
prevented.
[0109] Also, in the shoulder portion 3, the inclination .theta.1 of
the plane on which the finger hanging concave portion 9 is to be
formed, with respect to the vertical axis is designed to be
preferably -10 to 30.degree.. This makes it easier to lift the
bottle container 1 because the finger hanging concave portion 9 is
easily gripped from above.
[0110] Also, if fingers are fit to the finger hanging concave
portion 9 when the inclination .theta.1 is in a range from -10 to
-5.degree., the first joints of the fingers are bent deeply, which
makes finger hanging better and this range of the inclination is
desirable. Moreover, when the inclination .theta.1 is in a range
from 15 to 30.degree., this is preferable because fingers are
easily fit to the finger hanging concave portion 9 from a clearance
formed above the finger hanging concave portion 9 among the bottle
containers 1 stood in line in a close contact condition when the
bottle containers 1 are packed in a casing.
[0111] Also, in the finger hanging concave portion 9, the
inclination .theta.2 of the side wall surface 10 formed on the
mouth portion 2 side with respect to the horizontal axis is
preferably 5 to 80.degree.. With this structure, an angle at which
fingers are easily hung is secured on the side wall surface 10 of
the finger hanging concave portion 9 and the certainty of the
finger hanging concave portion 9 about finger hanging is therefore
improved.
[0112] The finger hanging concave portion 9 of the first embodiment
has a pentagonal form (the shape of a piece of Japanese chess or
home plate form) as the front shape wherein the upper two sides are
inclined in a mountain form by .theta.3 with respect to the
horizontal axis, and the lateral two sides extends upward to the
mouth portion from both ends of the bottom and are inclined inward
by .theta.4 with respect to the vertical axis. Here, the angle
.theta.3 is preferably in a range from 5 to 60.degree. and the
angle .theta.4 is preferably in a range from 0 to 60.degree..
Because this improves the balance between the lateral size and
vertical size of the finger hanging concave portion 9, not only the
gripping ability of the finger hanging concave portion 9 is
improved but also a deterioration in the appearance of the bottle
container 1 can be prevented. When .theta.4 is 0, the finger
hanging concave portion 9 has a home plate-type pentagonal
form.
[0113] Also, an anti-slipping portion 12 may be formed on the side
wall surface 10 and bottom surface 11 of the finger hanging concave
portion 9 by forming projections, convex ribs, grooves or steps.
Such a structure can limit slippage of fingers on the finger
hanging concave portion 9 to thereby improve the gripping ability
of the finger hanging concave portion 9.
[0114] Also, a shrink label may be attached to the bottle container
1 of the present invention. In this case, it is preferable to
utilize the step connecting the shoulder portion 3 with the body
portion 4 as an off-stopper to prevent the upper end of the shrink
label from coming off, thereby preventing the shrink label from
covering the finger hanging concave portion 9.
[0115] In the bottle container 1 according to this embodiment of
the present invention, as shown in FIGS. 1 to 3 and 5, a second
finger hanging concave portion 13 serving as finger grip when the
content is extracted from the mouth portion 2 by tilting the bottle
container 1 is formed on at least a pair of opposite surfaces at
the lower end of the above body portion 4. When the bottle
container 1 has such a structure, the tilted bottle container 1 can
be supported stably by gripping the finger concave portion 9 and
also gripping the second finger hanging concave portion 13 formed
at the lower end of the body portion 4 by another hand when the
bottle container 1 is tilted to extract the content from the mouth
portion 2.
[0116] Also, when the sectional shape of the body portion 4 is
almost rectangular, the second finger hanging concave portion 13 is
preferably formed on the longitudinal side of the rectangle. With
this structure, the pair of finger hanging concave portions 13 can
be gripped by one hand even in the case of a large capacity
container.
[0117] Specifically, the lateral distance L7 between the lower ends
of the pair of finger hanging concave portions 13 is preferably
designed to be 55 to 100 mm. It is thereby possible to improve
gripping ability because a proper distance is secured between
fingers gripping the container when the pair of the finger hanging
concave portions 13 are gripped.
[0118] The depth D2 of the second finger hanging concave portion 13
is preferably 3 to 15 mm. Such a structure brings about the
situation where a depth allowing fingers to be easily hung is
secured in the finger hanging concave portion 13 and the certainty
of the finger hanging concave portion 13 about finger hanging is
therefore improved.
[0119] Also, the maximum vertical width L8 of the second finger
hanging concave portion 13 is designed to be preferably 50 mm or
less and more preferably 15 to 40 mm. With this structure, a
vertical width large enough for the fingers is secured in the
finger hanging concave portion 13 and therefore, it is easy to hang
fingers on the finger hanging concave portion 13.
[0120] Also, the maximum lateral width L9 of the second finger
hanging concave portion 13 is designed to be preferably 90 mm or
less and more preferably 30 to 70 mm. This ensures that plural
fingers can be hung on the finger hanging concave portion 13 and it
is therefore easy to support the bottle container 1.
[0121] Also, the ratio L9/L6 of the maximum lateral width L9 of the
second finger hanging concave portion 13 to the lateral width
(longitudinal side) L6 of the body portion 4 is preferably 0.7 or
less and more preferably 0.25 to 0.6. This ensures that because the
size of the finger hanging concave portion 13 is allowed to accord
with the size of the bottle container 1, not only the gripping
ability of the finger hanging concave portion 13 is improved but
also a deterioration in the appearance of the bottle container 1
can be prevented.
[0122] Also, in the lower end portion of the body portion 4, the
inclination .theta.5 of the plane on which the second finger
hanging concave portion 13 is formed, with respect to the vertical
axis is designed to be preferably -10 to 30.degree.. This makes it
easier to support the tilted bottle container 1 because the finger
hanging concave portion 13 is easily gripped from the bottom 5
side.
[0123] Also, in the second finger hanging concave portion 13, the
inclination .theta.6 of the side wall surface 14 formed on the
bottom 5 side, with respect to the horizontal axis is preferably 5
to 80.degree.. With this structure, an angle at which fingers are
easily hung is secured on the side surface 14 of the finger hanging
concave portion 13 and the certainty of the finger hanging concave
portion 13 about finger hanging is therefore improved.
[0124] The second finger hanging concave portion 13 in this
embodiment is designed to have an inverse trapezoidal form as the
front form. However, it is needless to say that this form may be
altered to an optional form.
[0125] Meanwhile, in this embodiment, an example provided with the
grip concave portion 7 is explained. However, this grip concave
portion 7 is unnecessarily required and even if this grip concave
portion 7 is not formed, this has no particular influence on the
effect of the present invention.
SECOND EMBODIMENT TO EIGHTH EMBODIMENT
[0126] Next, bottle containers according to a second embodiment to
an eighth embodiment in the present invention will be explained
with reference to FIGS. 6 to 12. The structures common to those
used in the first embodiment are represented by the same symbols
that are used in the first embodiment and the explanations in the
first embodiment are quoted in these embodiments.
[0127] Each bottle container 1 in the second embodiment to sixth
embodiment has almost the same whole shape as the bottle container
1 of the first embodiment except that the shape of the finger
hanging concave portion 9 is different.
[0128] FIG. 6(A) is a plan view showing the upper portion of the
bottle container according to the second embodiment of the present
invention, FIG. 6(B) is a front view showing the upper portion of
the bottle container according to the second embodiment of the
present invention, and FIG. 6(C) is a side view showing the upper
portion of the bottle container according to the second embodiment
of the present invention.
[0129] The bottle container of this embodiment is an upper side
circular arc type in which the upper side of the finger hanging
concave portion 9 has a circular arc form. In this embodiment, the
radius R1 of the upper side circular arc portion is preferably
designed to be 20 to 40 mm. Other portions are designed to be the
same as those in the bottle container of the first embodiment. In
the bottle container of the second embodiment constituted in this
manner, the same effect that is obtained by the bottle container of
the first embodiment can also be obtained.
[0130] FIG. 7(A) is a plan view showing the upper portion of the
bottle container according to the third embodiment of the present
invention, FIG. 7(B) is a front view showing the upper portion of
the bottle container according to the third embodiment of the
present invention and FIG. 7(C) is a side view showing the upper
portion of the bottle container according to the third embodiment
of the present invention.
[0131] The bottle container of this embodiment has the finger
hanging concave portion 9 which shaped like a boiled fish cake
(i.e. "KAMABOKO" in Japanese) in which the upper side and left and
right sides of the finger hanging concave portion 9 have a circular
arc form. In this embodiment, the radius R2 of the upper side
circular arc portion is preferably designed to be 20 to 40 mm.
Other portions are designed to be the same as those in the bottle
container of the first embodiment. In the bottle container of the
third embodiment constituted in this manner, the same effect that
is obtained by the bottle container of the first embodiment can
also be obtained.
[0132] FIG. 8(A) is a plan view showing the upper portion of the
bottle container according to the fourth embodiment of the present
invention, FIG. 8(B) is a front view showing the upper portion of
the bottle container according to the fourth embodiment of the
present invention and FIG. 8(C) is a side view showing the upper
portion of the bottle container according to the fourth embodiment
of the present invention.
[0133] The bottle container of this embodiment is so designed that
the inclination of the upper side of the finger hanging concave
portion 9 with respect to the horizontal axis is 0.degree. and is
specifically a bottle container obtained by setting the inclination
.theta.3 in the first embodiment to 0.degree.. Except for this, the
bottle containers of this embodiment have the same trapezoidal
square shape having four sides as that of the first embodiment.
Here, the upper side lateral width L10 of the finger hanging
concave portion 9 is designed to be preferably 20 to 50 mm. Even in
this structure, plural fingers can be hung on the finger hanging
concave portion 9 and it is therefore easy to lift the bottle
container 1.
[0134] Also, the ratio L10/L5 of the upper side lateral width L10
to lower side lateral width L5 of the finger hanging concave
portion 9 is preferably 0.4 to 0.8. This ensures that because the
size of the finger hanging concave portion 9 is allowed to accord
with the size of the bottle container 1, not only the gripping
ability of the finger hanging concave portion 9 is improved but
also a deterioration in the appearance of the bottle container 1
can be prevented.
[0135] Other portions are designed to be the same as those of the
first embodiment. The same effect that is obtained by the bottle
container in the first embodiment is also obtained by the bottle
container in fourth embodiment constituted in this manner.
[0136] In other examples of this embodiment in which the finger
hanging concave portion 9 has a square form, modified examples
having a finger hanging concave portion 9 having a rectangular
form, square form or rhomboid form are considered.
[0137] FIG. 9(A) is a plan view showing the upper portion of the
bottle container according to the fifth embodiment of the present
invention and FIG. 9(B) is a front view showing the upper portion
of the bottle container according to the fifth embodiment of the
present invention.
[0138] The bottle container of this embodiment is so designed that
the inclination .theta.3+.theta.4 of the finger hanging concave
portion 9 of the first embodiment is 90.degree.. Except for this,
the bottle containers of this embodiment have the same triangular
type having three sides as that of the first embodiment. In this
embodiment, the inclination .theta.7 of the oblique side with
respect to the bottom side (horizontal axis) in the finger hanging
concave portion 9 is preferably 15 to 60.degree.. With this
structure, an angle at which fingers are easily hung is secured on
the side surface 14 of the finger hanging concave portion 13 and
the certainty of the finger hanging concave portion 13 about finger
hanging is therefore improved. Other portions are designed to be
the same as those of the first embodiment. The same effect that is
obtained by the bottle container in the first embodiment is also
obtained by the bottle container in the fifth embodiment
constituted in this manner.
[0139] The triangular form of the finger hanging concave portion 9
is preferably an isosceles triangle (including an equilateral
triangle) in view of gripping easiness and appearance.
[0140] FIG. 10(A) is a plan view showing the upper portion of the
bottle container according to the sixth embodiment of the present
invention and FIG. 10(B) is a front view showing the upper portion
of the bottle container according to the sixth embodiment of the
present invention. FIG. 11(A) is a plan view showing the upper
portion of the bottle container according to the seventh embodiment
of the present invention and FIG. 11(B) is a front view showing the
upper portion of the bottle container according to the seventh
embodiment of the present invention. FIG. 12 is a sectional view
showing the upper portion of the bottle container according to the
eighth embodiment of the present invention.
[0141] As shown in these figures, the finger hanging concave
portion 9 of the sixth embodiment is designed to have a circular
form (including an ellipsoidal or elliptic form). Also, the bottle
container 1 of the seventh embodiment has an almost square section
and a heptagonal finger hanging concave portion 9 is formed on two
pairs of surfaces opposite to each other in the shoulder portion 3.
Even if the finger hanging concave portion 9 is formed in this
manner, the same effect that is obtained in the first embodiment
can be produced. In, also, the sixth and seventh embodiments, L1 to
L6, .theta.1 and .theta.2 are preferably set to the same ranges
that are defined in the first embodiment.
[0142] The bottle container 1 of the eighth embodiment shown in
FIG. 12 is different from the foregoing embodiment in the point
that projections 15 continued to the side wall surface 10 of the
mouth portion 2 side are formed on the upper portion of the finger
hanging concave portion 9. This structure makes it possible to
prevent slippage when gripping the finger hanging concave portion
9, without fail to improve the gripping ability of the finger
hanging concave portion 9.
[0143] The embodiment of the finger hanging concave portion 9 is
not limited to the foregoing embodiment but may be those shown in
FIGS. 13(A) to (F). FIGS. 13(A) to (F) respectively show plan views
and sectional views of the finger hanging concave portion 9.
[0144] Here, FIG. 13 (A) shows an embodiment in which the depth of
the bottom surface of the finger hanging concave portion 9 is
gradually increased, FIGS. 13(B) and (C) show embodiments in which
a multistage bottom surface is formed and FIG. 13(D) shows an
embodiment in which projections are formed apart from the side wall
surface on the bottom surface. Also, it is possible to gradually
vary the inclination of the side wall surface of the finger hanging
concave portion 9 as shown in FIG. 13(E) or to make the slant
surface have an arc form as shown in FIG. 13(D). Moreover, as shown
in FIG. 13(F), the finger hanging concave portion 9 may have such a
form that the opening has a pentagonal form and the bottom surface
has a triangular form.
[0145] Also, though not shown, the bottom surface of the finger
hanging concave portion 9 is not limited to a flat form but may be
made into various forms, for example, various three-dimensional
shapes such as an inwardly convexed sphere shape.
NINTH EMBODIMENT
[0146] Next, a bottle container according to a ninth embodiment in
the present invention will be explained with reference to FIGS. 14
to 17. The structures common to those used in the aforementioned
each embodiment are represented by the same symbols that are used
in this embodiment and the explanations in the first embodiment are
quoted in this embodiment.
[0147] The bottle container 1 in the ninth embodiment has almost
the same whole shape as the bottle container 1 of the first
embodiment except that fold lines FL1 to FL3 are formed at
predetermined positions with respect to the finger hanging concave
portions 9 and 13 to make it easy to crush the shoulder portion 3
and the lower end portion of the body portion 4 in the bottle
container 1 with the intention of decreasing the volume of the
bottle container 1, thereby attaining a decrease in the volume of
wastes when the bottle container 1 is treated as waste after
used.
[0148] FIG. 14 is a front view of the bottle container according to
the ninth embodiment of the present invention. FIG. 15 is a side
view of the bottle container according to the ninth embodiment of
the present invention. FIG. 16 is a front view showing the upper
portion of the bottle container according to the ninth embodiment
of the present invention. FIG. 17 is a front view showing the lower
portion of the bottle container according to the ninth embodiment
of the present invention.
[0149] In these figures, the portions where the fold lines are
formed are each enclosed by a dotted line.
[0150] The bottle container 1 in this embodiment has a pentagonal
front shape in the same manner as in the first embodiment wherein a
pair of finger hanging concave portions 9 each having an apex 9a on
the side of the mouth portion 2 side are formed on the front side
and backside of the shoulder portion 3. Then, a first fold line FL1
is formed on the surface between the finger hanging concave portion
9 and the mouth portion 2 such that it is positioned on the line
crossing the apex 9a on the mouth portion 2 side of the finger
hanging concave portion 9. As is illustrated, this fold line FL1 is
preferably formed in such a manner as to extend to almost the
center in the direction of the width of the surface between the
finger hanging concave portion 9 and the mouth portion 2.
[0151] Such a structure ensures that when the surface on which the
finger hanging concave portion 9 of the shoulder portion 3 is
formed is pressed from the outside to reduce the volume of the
bottle container 1 in waste treatment after the bottle container is
used, the shoulder portion 3 is crushed while the surface
positioned between the finger hanging concave portion 9 and the
mouth portion 2 is bent along the fold line FL1.
[0152] The shoulder portion 3 of an angular type bottle container
like the bottle container 1 of the present embodiment is designed
to have an almost pyramid form and has relatively high rigidity so
that it is difficult to crush the bottle container. If the bottle
container is made to have the same structure as in this embodiment,
the shoulder portion 3 is easily crushed. Particularly, when the
fold line FL1 is formed such that it is positioned on the line
crossing the apex 9a on the mouth portion 2 side of the finger
hanging concave portion 9 and in other words, when the apex 9a on
the mouth portion 2 side of the finger hanging concave portion 9 is
positioned on the line extended from the fold line FL1, stress
tends to be concentrated on the fold line FL1, the shoulder portion
3 is easily bent along the fold line FL1.
[0153] Also, in this embodiment, a second fold line FL2 is formed
which extends laterally from each vicinity of angular portions 9b
positioned on the right and left sides of the finger hanging
concave portion 9b and preferably from each vicinity of the angular
portions 9b positioned on the right and left sides of the bottom
sides of the finger hanging concave portion 9b as illustrated,
respectively. This structure ensures that the shoulder portion 3 is
eventually crushed while bent along both the first fold line FL1
and the second fold line FL2 and the shoulder portion 3 is
therefore easily crushed.
[0154] Also, in the bottle container 1 of this embodiment, a second
finger hanging concave portion 13 is formed at the lower end
portion of the body portion 4 in the same manner as in the bottle
container of the first embodiment. Then, a third fold line FL3 is
formed which extends laterally from each vicinity of angular
portions 13a positioned on the right and left sides of the finger
hanging concave portion 13 and preferably from each vicinity of the
angular portions 13a positioned on the right and left sides of the
upper side of the finger hanging concave portion 13 as illustrated,
respectively. This structure ensures that the lower end portion of
the body portion 4 is eventually crushed while bent along the fold
line FL3.
[0155] As mentioned above, the bottom portion 5 is a portion which
functions as the bottom wall of the bottle container 1 and also as
a foot portion enabling the bottle container 1 to stand on its own
bottom and has higher rigidity than other portions. Therefore,
generally, the lower end portion of the body portion 4 near to the
bottom portion 5 is a portion which is also crushed with
difficulty. However, if a bottle container is formed according to
this embodiment, the lower end of the body portion 4 can be easily
crushed.
[0156] Also, in this embodiment, a fourth fold line FL4 is formed
on each side surface of the bottle container 1 as shown in FIG. 15,
which eventually makes it possible to crush the whole of the bottle
container 1 more easily.
[0157] The fourth fold line FL4 formed on the side surface of the
bottle container 1 is preferably, as shown in the figure,
constituted of a straight line portion extending vertically through
the central portion in the direction of the width of the side
surface of the body portion 4, an upper Y-shaped portion that is
branched in two directions on the line extending from the second
fold line FL2 formed in the shoulder portion 3 and is directed to
the mouth portion 2 and a lower Y-shaped portion that is branched
in two directions on the line extending from the third fold line
FL3 formed in the lower end of the body portion 4 and is directed
to the bottom portion 5. In the fourth fold line FL4 like this, the
upper and lower Y-shaped portions are made to branch on the lines
extended from the second fold line FL2 and the third fold line FL3
respectively, whereby the side surface of the bottle container 1 is
easily bent along these fold lines, with the result that the bottle
container 1 can be crushed more easily.
[0158] This embodiment is, as mentioned above, so designed that
when the fold lines FL1 to FL3 are formed, the positions where
these fold lines are to be formed are predetermined positions with
respect to the finger hanging concave portions 9 and 13 so as to
concentrate stress on these fold lines FL1 to FL3 to make it easy
to crush the bottle container 1 by bending the shoulder portion 3
and the lower end portion of the body portion 4 along the fold
lines FL1 to FL3. In addition, the fourth fold line FL4 is formed
on each side surface of the bottle container 1 together with these
fold lines FL1 to FL3 thereby making it easy to crush the whole of
the bottle container 1.
[0159] Here, though these fold lines FL1 to FL4 may be formed as a
convex ridge line or concave valley line extended on the surface of
the bottle container 1, it is unnecessary to form these lines such
that they can be observed as distinctive lines on the surface of
the bottle container 1. It is only required for these fold lines to
guide so as to bend the predetermined position of the bottle
container 1 along these lines. These lines may be formed as a
series of intermittent lines including a convex ridge line, concave
valley line or combination of these lines.
[0160] Also, the apex 9a of the mouth portion 2 side of the finger
hanging concave portion 9 may be formed as one made angular to some
extent in the same manner as in the first embodiment or as an
arc-like upper side top portion (portion closest to the mouth
portion 2) in the same manner as in second and third
embodiments.
TENTH EMBODIMENT
[0161] Next, the bottle container according to the tenth embodiment
of the present invention will be explained with reference to FIGS.
18 and 19. The structures common to those used in the
aforementioned each embodiment are represented by the same symbols
that are used in this embodiment and the explanations in each
embodiment are quoted in this embodiment.
[0162] A bottle container 1 of the tenth embodiment is a large
container having a capacity of 4000 ml wherein, like the ninth
embodiment, fold lines FL1 to FL3 are formed at predetermined
positions with respect to the finger hanging concave portions 9 and
13 respectively to thereby make it easy to crush the shoulder
portion 3 and the lower end portion of the body portion 4 in the
bottle container 1 and also, a fourth fold line FL4 is formed on
each side surface of the bottle container 1 whereby the whole
bottle container 1 can be crushed more easily.
[0163] FIG. 18 is a front view of the bottle container according to
the tenth embodiment of the present invention and FIG. 19 is a side
view of the bottle container according to the tenth embodiment of
the present invention. In also these figures, the portions where
fold lines are formed are enclosed by dotted lines to show
them.
[0164] The bottle container 1 of this embodiment has the finger
hanging concave portion 9 which shaped like a boiled fish cake
(i.e. "KAMABOKO" in Japanese) in which the upper side and left and
right sides of the finger hanging concave portion 9 have a circular
arc form in the same manner as in the third embodiment. However, a
finger receiving concave portion 90 curved in a convex form toward
the inside of the container is formed in such a manner as to notch
the bottom side of the finger hanging concave portion 9 and more
specifically, the side wall surface on the bottom side of the
finger hanging concave portion 9.
[0165] The formation of such a finger receiving concave portion 90
has the advantage that when the finger hanging concave portion 9 is
gripped, another finger such as the middle finger or fourth finger
other than two fingers including the thumb and forefinger or middle
finger can be received in the finger receiving concave portion 90
with allowing the another finger to approach towards the fingers
gripping the finger hanging concave portion 9 whereby the another
finger is allowed to apply force. In addition, fingers can be
received in such a manner as to embrace the balls of these fingers
by making the finger receiving concave portion have a shape curved
in a convex form toward the inside of the container.
[0166] This brings about the advantage that the finger hanging
concave portion 9 in the bottle container 1 of this embodiment is
easily gripped, so that the bottle container 1 can be lifted more
easily by gripping the finger hanging concave portion 9.
[0167] Although the invention has been described in its preferred
form, the present invention is not limited to the above embodiment.
It is needless to say that various modifications and variations are
possible within the scope of the present invention.
[0168] Also, the present invention may have a structure including a
proper combination of individual structures of the aforementioned
embodiments.
INDUSTRIALLY APPLICABILITY
[0169] The present invention may be applied to a container, such as
a pet bottle, provided with a mouth portion, a shoulder portion, a
body portion and a bottom portion. The present invention is
suitable to a container that needs to be easily taken out even in
the situation where it is packed in a casing or received in a
refrigerator.
