DETAILED DESCRIPTION OF THE INVENTION
[0034] In a case of the container of Patent Document 1, there is
room for improvement in terms of holdability for a user (degree of
easiness for the user to hold).
[0035] The present invention relates to a container having a
structure with favorable holdability for a user, and also relates
to a contents-packed container.
[0036] Below, preferred exemplary embodiments according to the
present invention will be described with reference to the drawings.
Note that, in all the drawings, the same reference characters are
attached to similar constituent components, and detailed
explanation thereof will not be repeated.
First Exemplary Embodiment
[0037] First, a first exemplary embodiment will be described with
reference to FIGS. 1 to 11.
[0038] The mode of a container according to the present invention
is not particularly limited. However, it may be possible to employ
a mode in which the container can stand independently, or a mode in
which the container does not stand independently and is expected to
be used in a lying position. In a case of this exemplary
embodiment, a container 100 includes a bottom gusset portion 13
(FIG. 1, FIG. 5), and is a freestanding container that can stand
independently in a state in which a bottom gusset portion 13 is
disposed on a horizontal mounting surface 71 as illustrated in FIG.
1.
[0039] In this exemplary embodiment, the positional relationship
(up-down relationship or the like) of each constituent element of
the container 100 is described in terms of a positional
relationship in a state in which the container 100 is caused to
stand independently as illustrated in FIG. 1, unless otherwise
specified. However, the positional relationship in this description
does not necessarily match the positional relationship at the time
of manufacturing the container 100 or at the time of using the
container 100.
[0040] In addition, in connection with the positional relationship
of each constituent element of the container 100, the positional
relationship illustrated in each of the drawings may be
described.
[0041] The front surface side (side toward the viewer of FIG. 1) of
the container 100 is referred to as a forward direction; the back
surface side (side away from the viewer of FIG. 1) of the container
100 is referred to as a rearward direction; the left side (left
side in FIG. 1) as viewed from the front surface of the container
100 is referred to as a leftward direction; and the right side
(left side in FIG. 1) as viewed from the front surface of the
container 100 is referred to as a rightward direction. Furthermore,
the left-right direction of the container 100 may be referred to as
a widthwise direction.
[0042] As illustrated in any of FIGS. 1 to 6, the container 100
according to the present exemplary embodiment includes a containing
portion 17 that is a closed space that stores contents 18, and a
container main body 20 that includes a body portion 11 that
surrounds the containing portion 17, and a handle portion 12 that
protrudes from the body portion 11.
[0043] Here, the body portion 11 is a portion that surrounds the
containing portion 17 in the container main body 20. The handle
portion 12 is a portion disposed outside of the body portion 11 in
the container main body 20. That is, the "handle portion 12 that
protrudes from the body portion 11" means that the body portion 11
and the handle portion 12 are connected to each other, and the
handle portion 12 is located outside of the body portion 11. The
handle portion 12 is a portion suitable for a user to grip it, and
allows the user to grip the handle portion 12 to lift the container
100 or discharge contents 18 (typically, let the contents 18 out)
from the containing portion 17 of the container 100.
[0044] As illustrated in FIG. 2, the container main body 20
includes a main-body forming sheet member 21 in which plural film
layers (in the case of this exemplary embodiment, two film layers
of an outer film 22 and an inner film 23) are stacked. The
main-body forming sheet member 21 includes a non-attached region 24
(FIG. 2) in which plural film layers are partially not attached to
each other, and also includes a filling portion 60 in which a
filler is contained between layers of the plural film layers of the
non-attached region 24.
[0045] The filler contained in the filling portion 60 includes a
fluid (gas or liquid), a solid (for example, a powder-granular
material, resin pellet, or the like), or a semi-solid (for example,
blowing agent or the like), and is preferably a gas such as
air.
[0046] The filling portion 60 includes a first filling portion 61
formed in the body portion 11, and a second filling portion 62
formed in the handle portion 12. In addition, the first filling
portion 61 and the second filling portion 62 communicate to each
other.
[0047] According to the present exemplary embodiment, since the
first filling portion 61 formed in the body portion 11 and the
second filling portion 62 formed in the handle portion 12 of the
container main body 20 communicate to each other, it is possible to
improve a structural strength at a boundary portion between the
body portion 11 and the handle portion 12. This allows suppression
of wobbling of the body portion 11 relative to the handle portion
12 when a user grips the handle portion 12 to lift the container
100, which makes it possible to stably hold the entire container
100. In this manner, with the present exemplary embodiment, it is
possible to provide a container 100 having a favorable structure in
terms of holdability for a user. It is also possible to achieve
favorable holdability, for example, even in a case of a container
100 having a large capacity (for example, equal to or more than 1
L).
[0048] Furthermore, a contents-packed container 200 according to
the present exemplary embodiment includes the container 100
according to the present exemplary embodiment, and contents 18
stored in the containing portion 17.
[0049] In the present invention, types of contents 18 are not
specifically limited. The contents 18 include, for example,
detergent, bleach, softener, shampoo, conditioner, body soap,
beverage, and food, and also include engine oil, chemical agent,
and the like.
[0050] In addition, the contents 18 may be a liquid (including a
form of paste), or may be a solid (for example, in a form of
particle (including a form of grain) or in a form of powder).
[0051] In the case of this exemplary embodiment, the contents 18
are, for example, a liquid.
[0052] In a case where the contents 18 are a liquid, the viscosity
of the contents 18 at, for example, 30.degree. C. preferably falls
in a range of equal to or more than 1 mPas and equal to or less
than 120000 mPas (measured by a B-type viscometer; for example,
measured using viscometer TV-10 or viscometer TVB-10 made by Toki
Sangyo Co., LTD. or the like), and more preferably falls in a range
of equal to or more than 1 mPas and equal to or less than 60000
mPas.
[0053] In the case of this exemplary embodiment, the container 100
includes an inner bag 40 (inner container) made out of an inner-bag
forming sheet member 41, as illustrated in FIG. 2. The inner bag 40
is surrounded by the container main body 20. The inner bag 40
includes the containing portion 17. The inner-bag forming sheet
member 41 is folded and peripheral edge portions of this inner-bag
forming sheet member 41 are attached to each other to form the
inner bag 40 having a bag shape.
[0054] However, in the present invention, the inner container is
not limited to that made out of a sheet member. For example, the
inner container may be formed through blow molding.
[0055] The shape of the front surface of the container 100, that
is, the shape of the front surface of the container main body 20 is
not specifically limited. However, in the case of this exemplary
embodiment, the shape of the front surface of the container main
body 20 is substantially an elongated quadrilateral shape as
illustrated, for example, in FIG. 1.
[0056] As illustrated in FIG. 2, the body portion 11 of the
container main body 20 includes a first main surface portion 20a
and a second main surface portion 20b, which are opposed to each
other with the containing portion 17 being disposed therebetween.
The first main surface portion 20a is disposed at the front surface
side, and the second main surface portion 20b is disposed at the
back surface side. The body portion 11 is formed into a bag shape
having a bottom gusset portion 13 and a top gusset portion 14.
[0057] The handle portion 12 of the container main body 20
protrudes toward the lateral direction (rightward direction in FIG.
1) from the body portion 11.
[0058] More specifically, the handle portion 12 is formed into a
semi-annular shape (C-shape (in FIG. 1, a shape obtained by
reversing the left and right of a C-shape), and both end portions
of the handle portion 12 are each connected to the body portion 11.
In addition, in the container main body 20, a penetrating portion
19 that penetrates through this container main body 20 (in a
forward-backward direction) is formed between the handle portion 12
and the body portion 11, as illustrated in FIG. 1. In the case of
this exemplary embodiment, the penetrating portion 19 is a
through-hole. However, the present invention is not limited to this
example, and the penetrating portion 19 may be a slit.
[0059] The way of gripping the handle portion 12 is not
specifically limited. However, as one example, a user can insert
four fingers from the second finger to the fifth finger of a hand
into the penetrating portion 19 to grip the handle portion 12 using
these four fingers together with the first finger to lift the
container 100.
[0060] The shape of the inner bag 40 is not specifically limited.
However, in the case of this exemplary embodiment, the inner bag 40
is formed into a shape similar to that of the container main body
20. Thus, the inner bag 40 includes a portion disposed inside of
the body portion 11 and constitutes the containing portion 17, and
a portion disposed inside of the handle portion 12.
[0061] The portion of the inner bag 40 that is disposed inside of
the body portion 11 is formed into a shape similar to that of the
body portion 11, and includes a first main surface portion 40a
located at the front surface side and a second main surface portion
40b located at the back surface side with the containing portion 17
being disposed therebetween. The portion of the inner bag 40 that
is disposed inside of the handle portion 12 is formed into a shape
similar to that of the handle portion 12.
[0062] The interior region of the portion of the inner bag 40 that
is disposed inside of the handle portion 12 is referred to as a
communicating region 49 (FIG. 2). The communicating region 49
communicates to the containing portion 17. In the case of this
exemplary embodiment, the communicating region 49 communicates to
the containing portion 17 at both end portions of the handle
portion 12.
[0063] As described above, the communicating region 49 that
communicates to the containing portion 17 is formed inside of the
handle portion 12. This makes it possible to increase, by the
amount of the communicating region 49, the capacity that can store
the contents 18 within the container 100, as compared with a case
where the container 100 does not include the communicating region
49.
[0064] In addition, the container 100 includes an inner container
(inner bag 40) that is surrounded by the container main body 20.
The inner container includes the containing portion 17 and the
communicating region 49.
[0065] In other words, a portion (a portion that constitutes the
communicating region 49) of the inner container is configured to
enter the handle portion 12. This configuration enables a portion
of the inner container to be retained within the handle portion 12
at the time of discharging the contents 18 from the container 100
(it is possible to prevent the inner container together with the
contents 18 from falling down relative to the container main body
20). This achieves favorable discharging property for the contents
18 from the container 100.
[0066] As described above, the body portion 11 of the container
main body 20 includes the bottom gusset portion 13 in the bottom
portion thereof, and also includes the top gusset portion 14 in the
upper end portion. In addition, a portion of the inner bag 40 that
is disposed inside of the body portion 11 and constitutes the
containing portion 17 is formed into a shape similar to that of the
body portion 11. This makes it possible to secure a sufficient
capacity of the containing portion 17.
[0067] The container 100 includes a discharge portion (for example,
a spout 15) that allows the contents 18 to be discharged from the
containing portion 17.
[0068] The position of the discharge portion in the container 100
is not specifically limited. However, in the case of this exemplary
embodiment, the discharge portion is disposed in an upper end
portion on a side opposite to the bottom portion. More
specifically, the spout 15 serving as the discharge portion is
provided so as to penetrate through the top gusset portion 14. The
spout 15 includes, for example, a cylindrical outlet cylinder
portion 15a through which the contents 18 are discharged, and a
plate shape portion 15b having a plate shape and provided at one
end of the outlet cylinder portion 15a in an axial direction so as
to be perpendicular to this axial direction, the outlet cylinder
portion 15a and the plate shape portion 15b being provided in an
integral manner. On the inner-bag forming sheet member 41, the
plate shape portion 15b is provided, for example, on an inner
surface or an external surface and at a portion disposed along the
top gusset portion 14 of the body portion 11.
[0069] The discharge portion is not limited to the spout. The
discharge portion may be a film valve having, for example, a
one-way function, or may be formed in the container 100 in a manner
such that the container 100 is broken along a to-be-torn portion as
in the sixth exemplary embodiment, which will be described
later.
[0070] Here, the central axis AX illustrated in FIG. 1 is a
vertical axis passing through the center of a plane of the bottom
gusset portion 13 when the container 100 is placed on the mounting
surface 71. The central axis AX is set to be the central axis of
the container 100. In the case of this exemplary embodiment, the
spout 15 is disposed on a side opposite to the handle portion 12 on
the basis of the central axis AX of the container 100, as
illustrated in FIG. 1. In FIG. 1, the handle portion 12 is disposed
on the right side relative to the central axis AX, and the spout 15
is disposed on the left side relative to the central axis AX.
[0071] That is, the container 100 includes the discharge portion
(spout 15) that allows the contents 18 to be discharged from the
containing portion 17. The discharge portion is disposed on a side
opposite to the handle portion 12 relative to the central axis AX
of the container 100.
[0072] With the discharge portion (spout 15) and the handle portion
12 having such a positional relationship, it is possible for a user
to more easily and stably perform an operation of gripping the
handle portion 12 to hold the container 100, and discharging the
contents 18 from the discharge portion.
[0073] In addition, in the case of this exemplary embodiment, the
outlet cylinder portion 15a leans toward a side opposite to the
handle portion 12. In other words, in FIG. 1, the axial direction
of the outlet cylinder portion 15a leans toward the left side. Such
a configuration makes it possible to more easily perform an
operation of discharging the contents 18 from the discharge
portion.
[0074] More specifically, the top gusset portion 14 includes a
first portion 14a and a second portion 14b continuously connected
to the forward side of the first portion 14a, as illustrated in
FIGS. 1 and 4.
[0075] For example, the first portion 14a is sloped downward toward
the rightward direction, or is disposed horizontally.
[0076] The second portion 14b is disposed on the left side of the
central axis AX, and is sloped downward toward the leftward
direction.
[0077] In addition, the plate shape portion 15b of the spout 15 is
disposed along the second portion 14b. With this configuration, the
axial direction of the outlet cylinder portion 15a leans toward the
left side.
[0078] The container 100 further includes a cap 16 that is
detachably attached to the outlet cylinder portion 15a of the spout
15. The cap 16 is, for example, of a screwed cap.
[0079] In addition, in the case of this exemplary embodiment, the
cap 16 closes an opening at the top end of the spout 15, which
allows the containing portion 17 to be a closed space. However, the
present invention is not limited to this example. As in other
exemplary embodiments described later, the containing portion 17
may be a closed space in a state in which the container 100 is
formed into a bag.
[0080] Next, an example of the filling portion 60 in the container
100 will be described in more detail.
[0081] In the case of this exemplary embodiment, the filling
portion 60 includes: a circular filling portion 63 (FIG. 5, FIG. 1)
formed into a circular shape along the peripheral edge of the
bottom gusset portion 13; sloped filling portions 64 and 65 and
body-portion vertically extending filling portions 66 and 67, each
of which is formed in a front surface side of the body portion 11,
that is, in the first main surface portion 20a; a vertically
extending filling portion 68 and intersecting filling portions 69
and 70 formed in the front surface side of the handle portion 12;
sloped filling portions 64 and 65 and body-portion vertically
extending filling portions 66 and 67 formed in the back surface
side of the body portion 11, that is, in the second main surface
portion 20b; and a vertically extending filling portion 68 and
intersecting filling portions 69 and 70 formed in the back surface
side of the handle portion 12.
[0082] The first filling portion 61 is configured to include the
sloped filling portions 64, 65, and the body-portion vertically
extending filling portions 66, 67 formed in the first main surface
portion 20a and the second main surface portion 20b.
[0083] The second filling portion 62 is configured to include the
vertically extending filling portion 68, and the intersecting
filling portions 69, 70 formed in the front surface side and the
back surface side of the handle portion 12.
[0084] In the case of this exemplary embodiment, the entire filling
portion 60 is formed in an integrated manner. However, in the
present invention, the container 100 may include plural filling
portions that are independent of each other.
[0085] A portion of the first filling portion 61 that is formed in
the first main surface portion 20a will be described. The lower end
of the sloped filling portion 64 communicates to the circular
filling portion 63 at a left-half portion of a lower end portion of
the first main surface portion 20a. The sloped filling portion 64
extends from the left-half portion of the lower end of the first
main surface portion 20a toward an obliquely left upward direction.
The lower end of the sloped filling portion 65 communicates to the
circular filling portion 63 at a right-half portion of the lower
end portion of the first main surface portion 20a. The sloped
filling portion 65 extends from the right-half portion of the lower
end of the first main surface portion 20a toward an obliquely right
upward. The sloped filling portion 64 and the sloped filling
portion 65 are arranged in a substantially left-right symmetry with
each other. The upper end of the sloped filling portion 64 is
continuously connected to the body-portion vertically extending
filling portion 66. The body-portion vertically extending filling
portion 66 extends vertically (from the upper end portion side of
the body portion to the bottom portion side) along the left edge
portion of the first main surface portion 20a. The upper end of the
sloped filling portion 65 is continuously connected to the
body-portion vertically extending filling portion 67. The
body-portion vertically extending filling portion 67 extends
vertically (from the upper end portion side of the body portion to
the bottom portion side) along the right edge portion of the first
main surface portion 20a.
[0086] In addition, one of or both of the body-portion vertically
extending filling portion 66 and the body-portion vertically
extending filling portion 67 may be sloped.
[0087] A portion of the first filling portion 61 that is formed in
the second main surface portion 20b is disposed, for example, so as
to be in a forward-backward symmetry with a portion of the first
filling portion 61 that is formed on the first main surface portion
20a.
[0088] A portion of the second filling portion 62 that is formed in
the front surface side of the handle portion 12 will be described.
The intersecting filling portion 69 is disposed, for example,
substantially horizontally in the upper portion of the handle
portion 12. The left end of the intersecting filling portion 69
communicates to the body-portion vertically extending filling
portion 67. That is, the intersecting filling portion 69 is a
communicating filling portion that extends toward the first filling
portion 61 and communicates to the first filling portion 61. A
portion where the intersecting filling portion 69 and the
body-portion vertically extending filling portion 67 communicate to
each other is disposed at a position lower than the upper end of
the body-portion vertically extending filling portion 67.
[0089] Here, a portion of the body-portion vertically extending
filling portion 67 that is disposed lower than the communicating
portion between the body-portion vertically extending filling
portion 67 and the intersecting filling portion 69 is an opposing
portion 67a that is opposed to the vertically extending filling
portion 68 with the penetrating portion 19 being disposed
therebetween. A portion of the body-portion vertically extending
filling portion 67 that is disposed higher than the communicating
portion between the body-portion vertically extending filling
portion 67 and the intersecting filling portion 69 is referred to
as an upward extending portion 67b.
[0090] The intersecting filling portion 70 is disposed in a lower
portion of the handle portion 12, and is disposed so as to be
opposed to the intersecting filling portion 69 with the penetrating
portion 19 being disposed therebetween. That is, the intersecting
filling portion 70 is disposed, for example, substantially
horizontally. In the present exemplary embodiment, the intersecting
filling portion 70 is also a communicating filling portion that
extends toward the first filling portion 61 and communicates to the
first filling portion 61 (sloped filling portion 65).
[0091] The vertically extending filling portion 68 extends
vertically. The upper end of the vertically extending filling
portion 68 and the right end of the intersecting filling portion 69
communicate to each other. The lower end of the vertically
extending filling portion 68 and the right end of the intersecting
filling portion 70 communicate to each other.
[0092] A portion of the second filling portion 62 that is formed on
the front surface side of the handle portion 12 is formed into a
semi-annular shape (C-shape (in FIG. 1, a shape obtained by
reversing the left and right of a C-shape)) along the handle
portion 12.
[0093] In addition, the vertically extending filling portion 68 may
be sloped.
[0094] A portion of the second filling portion 62 that is formed on
the back surface side of the handle portion 12 is disposed, for
example, so as to be in a forward-backward symmetry with a portion
of the second filling portion 62 that is formed on the front
surface side of the handle portion 12.
[0095] In the present exemplary embodiment, both end portions of a
portion of the second filling portion 62 that is formed on the
front surface side of the handle portion 12 each communicates to
the first filling portion 61. In addition, both end portions of a
portion of the second filling portion 62 that is formed on the back
surface side of the handle portion 12 each communicate to the first
filling portion 61. However, the present invention is not limited
to this example. It may be possible to employ a configuration in
which only either one of both end portions of the portion of the
second filling portion 62 that is formed on the front surface side
of the handle portion 12 communicates to the first filling portion
61, or a configuration in which only either one of both end
portions of the portion of the second filling portion 62 that is
formed on the back surface side of the handle portion 12
communicates to the first filling portion 61.
[0096] That is, the second filling portion 62 is formed into a
semi-annular shape, and at least either one of both end portions of
the second filling portion 62 communicates to the first filling
portion 61.
[0097] More specifically, the body-portion vertically extending
filling portion 67 of the first filling portion 61 and the second
filling portion 62 communicate to each other at a boundary portion
between the body portion 11 and the handle portion 12. With the
body-portion vertically extending filling portion 67 and the second
filling portion 62 directly communicating to each other as
described above, it is possible to improve structural strength
(load carrying property) particularly against load acting in the
vertical direction, which makes it possible to further suppress
wobbling of the body portion 11 relative to the handle portion 12
when a user grips the handle portion 12 to lift the container
100.
[0098] In particular, an attached portion 48c in which plural film
layers (the outer film 22 and the inner film 23) are attached to
each other is continuously formed along the entire region in which
the body-portion vertically extending filling portion 67 extends,
the attached portion 48c being provided in at least one of regions
located at both sides of the body-portion vertically extending
filling portion 67 in a direction perpendicular to a direction in
which the body-portion vertically extending filling portion 67
extends. Since the body-portion vertically extending filling
portion 67 and the attached portion 48c having increased rigidity
extend in the vertical direction as described above, it is possible
to improve the structural strength (load carrying property) against
load acting in the vertical direction, which makes it possible to
achieve favorable holdability at the time of lifting the container
100.
[0099] It is preferable that the body-portion vertically extending
filling portion 67 and the attached portion 48c are formed
continuously at least from a height position corresponding to an
upper-side connecting portion to a height position corresponding to
a lower-side connecting portion from among connecting portions (two
connecting portions) of both end portions of the handle portion 12
to the body portion 11. That is, it is preferable that the upper
end position of the body-portion vertically extending filling
portion 67 and the upper end position of the attached portion 48c
are disposed higher than the upper end position of the penetrating
portion 19, and the lower end position of the body-portion
vertically extending filling portion 67 and the lower end position
of the attached portion 48c are disposed lower than the lower end
position of the penetrating portion 19. The upper end position of
the body-portion vertically extending filling portion 67 and the
upper end position of the attached portion 48c may be disposed
lower than the upper end position of the body portion 11, or may be
equal to this upper end position. The lower end position of the
body-portion vertically extending filling portion 67 and the lower
end position of the attached portion 48c may be disposed higher
than the lower end position of the body portion 11, or may be equal
to the lower end position.
[0100] In addition, the attached portion in which plural film
layers (the outer film 22 and the inner film 23) that constitute
the main-body forming sheet member 21 are attached to each other is
not limited to the attached portion 48c illustrated in FIG. 1, and
is formed in an entire region adjacent to the periphery of the
filling portion 60. In other words, the shape of the filling
portion 60 is defined by the attached portion that surrounds a
non-attached region 24, which will be described later.
[0101] In the case of this exemplary embodiment, the penetrating
portion 19 is surrounded by a portion of the second filling portion
62 that is formed on the front surface side of the handle portion
12, and is also surrounded by a portion of the second filling
portion 62 that is formed on the back surface side of the handle
portion 12.
[0102] This makes it possible to insert fingers (for example, four
fingers from the second finger to the fifth finger) into the
penetrating portion 19 and also grip, using a hand, the handle
portion 12 having a semi-annular shape and reinforced by the second
filling portion 62, thereby achieving the handle portion 12 having
more favorable gripping property.
[0103] The filling portion 60 includes a first parallel extending
portion (opposing portion 67a) and a second parallel extending
portion (vertically extending filling portion 68) that are opposed
to each other with the penetrating portion 19 being disposed
therebetween, the first parallel extending portion and the second
parallel extending portion extending in parallel to each other. The
first filling portion 61 includes the first parallel extending
portion, and the second filling portion 62 includes the second
parallel extending portion.
[0104] With the filling portion 60 including the first parallel
extending portion and the second parallel extending portion, it is
possible to achieve a structure having favorable gripping property
of the container 100 and favorable shape keeping property of the
body portion 11.
[0105] Here, the "first parallel extending portion and the second
parallel extending portion that extend in parallel to each other"
does not only mean a structure in which the first parallel
extending portion and the second parallel extending portion extend
in parallel to each other. The direction in which the first
parallel extending portion extends and the direction in which the
second parallel extending portion extends may slightly (for
example, equal to or less than 30 degrees) differ from each other.
It is preferable that a difference in angle between the direction
in which the first parallel extending portion extends and the
direction in which the second parallel extending portion extends is
equal to or less than 10 degrees. In addition, in a case where the
direction in which the first parallel extending portion extends and
the direction in which the second parallel extending portion
extends differ from each other, it is preferable that these
directions are set such that the angle formed by these extending
directions expands from the bottom portion toward the direction of
top surface (directions spread in a form of inverted V-shape), from
the viewpoint of improvement of the gripping property.
[0106] The direction in which the intersecting filling portion 69
extends and the direction in which the intersecting filling portion
70 extends intersect the direction in which the vertically
extending filling portion 68 extends. The angle formed by the
direction in which the vertically extending filling portion 68
extends relative to the direction in which the intersecting filling
portion 69 extends and the direction in which the intersecting
filling portion 70 extends is not specifically limited. However,
for example, this angle is preferably equal to or more than 60
degrees and equal to or less than 120 degrees, and is more
preferably equal to or more than 70 degrees and equal to or less
than 110 degrees.
[0107] In addition, from the viewpoint of the gripping property and
the shape keeping property of the handle portion 12, it is
preferable that the filling portion having a substantially
parallelogram shape is comprised of the intersecting filling
portion 69, the vertically extending filling portion 68, the
intersecting filling portion 70, and the opposing portion 67a.
[0108] The relationship between the lengths of the intersecting
filling portion 69 and the intersecting filling portion 70 and the
lengths of the vertically extending filling portion 68 and the
opposing portion 67a is not specifically limited. However, it is
preferable that the lengths of the vertically extending filling
portion 68 and the opposing portion 67a are longer than the lengths
of the intersecting filling portion 69 and the intersecting filling
portion 70.
[0109] In the case of this exemplary embodiment, the second filling
portion 62 includes an intersecting extending portion (intersecting
filling portion 69) that extends in a direction that intersects the
first parallel extending portion (opposing portion 67a). One end of
the intersecting extending portion communicates to the first
parallel extending portion, and the other end of the intersecting
extending portion communicates to the second parallel extending
portion (vertically extending filling portion 68).
[0110] In addition, the second filling portion 62 further includes
a second intersecting extending portion (intersecting filling
portion 70) that extends in parallel to the intersecting extending
portion (intersecting filling portion 69).
[0111] Furthermore, one end of the second intersecting extending
portion (intersecting filling portion 70) communicates to the first
parallel extending portion (opposing portion 67a), and the other
end of the second intersecting extending portion communicates to
the second parallel extending portion (vertically extending filling
portion 68).
[0112] Furthermore, the body-portion vertically extending filling
portion 67 of the first filling portion 61 includes the opposing
portion 67a that extends downward from the communicating portion
between the body-portion vertically extending filling portion 67
and the intersecting filling portion 69, and also includes the
upward extending portion 67b that extends upward from this
communicating portion.
[0113] That is, the body-portion vertically extending filling
portion 67 includes a first-direction extending portion (opposing
portion 67a) that extends in a first direction from the
communicating portion between the body-portion vertically extending
filling portion 67 and the second filling portion 62, and also
includes a second-direction extending portion (upward extending
portion 67b) that extends from the communicating portion in a
second direction differing from the first direction. Such a
structure allows an improvement of the shape keeping property of
the body portion 11 and the stability of the handle portion 12
relative to the body portion 11.
[0114] In the case of this exemplary embodiment, the second
parallel extending portion (vertically extending filling portion
68) is formed so as to be larger in diameter than the first
parallel extending portion (opposing portion 67a). This allows
further improvement of the shape keeping property of the handle
portion 12.
[0115] More specifically, in the case of this exemplary embodiment,
the opposing portion 67a is formed larger in diameter than the
body-portion vertically extending filling portion 66. This allows
further improvement of the shape keeping property of the body
portion 11 when a user grips the handle portion 12 to hold the
container 100.
[0116] Yet more specifically, the upward extending portion 67b is
formed larger in diameter than the body-portion vertically
extending filling portion 66. In addition, the sloped filling
portion 65 is formed larger in diameter than the sloped filling
portion 64. These structures also allow further improvement of the
shape keeping property of the body portion 11 when a user grips the
handle portion 12 to hold the container 100. Furthermore, with the
diameters of the body-portion vertically extending filling portion
66 and the sloped filling portion 64 being reduced, it is also
possible to increase the capacity of the inner bag, which makes it
possible to increase the amount of the contents filled.
[0117] Furthermore, the body-portion vertically extending filling
portion 67 includes the upward extending portion 67b that extends
more upward than the communicating portion between the body-portion
vertically extending filling portion 67 and the intersecting
filling portion 69, which makes it possible to improve the shape
keeping property of a portion of the body portion 11 higher than
this communicating portion. This enables the contents 18 to be
stored to a higher position in the containing portion 17 in the
body portion 11.
[0118] In the case of this exemplary embodiment, the handle portion
12 includes a handle-portion sealing portion in which plural film
layers of the main-body forming sheet member 21 are attached to
each other (directly or indirectly), the handle-portion sealing
portion being provided on each of the outer peripheral side and the
inner peripheral side of the handle portion 12. Of these portions,
the handle-portion sealing portion on the outer peripheral side of
the handle portion 12 is referred to as a handle-portion sealing
portion 48a (FIG. 1), and a handle-portion sealing portion on the
inner peripheral side (on a side facing the penetrating portion 19)
of the handle portion 12 is referred to as a handle-portion sealing
portion 48b (FIG. 1).
[0119] The handle-portion sealing portion may be configured by
directly attaching the outer film 22 and the inner film 23 of the
main-body forming sheet member 21, or may be configured by
attaching the outer film 22 and the inner film 23 through an
intervening layer (for example, inner-bag forming sheet member 41
or the like).
[0120] In the case of this exemplary embodiment, the second filling
portion 62 extends along the handle portion 12 having a
semi-annular shape. The "second filling portion 62 extending along
the handle portion 12" means that the second filling portion 62
extends along at least a portion of the handle portion 12. In
addition, in the case of this exemplary embodiment, a narrow
portion 72 is formed at an intermediate portion between both ends
of the second filling portion 62. In the case of this exemplary
embodiment, the narrow portion 72 is formed in the second filling
portion 62 on the outer peripheral side of the handle portion 12.
Thus, at least a portion of the handle-portion sealing portion 48a
on the outer peripheral side is inclined toward the forward side or
the rearward side. This provides soft texture at the time of
gripping the handle portion 12.
[0121] However, the present invention is not limited to this
example. A bent portion may be formed at the intermediate portion
between both ends of the second filling portion 62, whereby at
least a portion of the handle-portion sealing portion 48a leans
toward the forward direction or the rearward direction.
[0122] That is, in the case of this exemplary embodiment, the
narrow portion 72 or the bent portion is formed at the intermediate
portion between both ends of the second filling portion 62.
[0123] In addition, the diameter of the second filling portion 62
may partially reduce between both ends of this second filling
portion 62. Even with such a configuration, it is possible to
achieve a structure in which the narrow portion 72 or the bent
portion is formed at the intermediate portion between both ends of
the second filling portion 62, and at least a portion of the
handle-portion sealing portion 48a leans toward the forward
direction or the rearward direction.
[0124] In a case where the bent portion is formed in the second
filling portion 62, it is possible to easily achieve a structure in
which not only the handle-portion sealing portion 48a on the outer
peripheral side but also at least a portion of the handle-portion
sealing portion 48b on the inner peripheral side leans toward the
forward direction or the rearward direction.
[0125] In the case of this exemplary embodiment, the width size of
the handle-portion sealing portion 48a on the outer peripheral side
of the handle portion 12 is larger than the width size of the
handle-portion sealing portion 48b on the inner peripheral side of
the handle portion 12. This allows the outer peripheral side of the
handle portion 12 to be reinforced. This makes it possible to
further improve the rigidity of the handle portion 12, and also
provide soft texture at a portion (handle-portion sealing portion
48b) where a fingertip touches in the handle portion 12.
[0126] In the case of this exemplary embodiment, a local attached
portion 29 in which plural film layers of the main-body forming
sheet member 21 are locally attached to each other is formed near
the communicating portion between the first filling portion 61 and
the second filling portion 62.
[0127] The "near the communicating portion" typically means a
position that is adjacent to the communicating portion. In the
present exemplary embodiment, the local attached portion 29 is
disposed at the communicating portion in an island manner, and the
periphery thereof is surrounded by the communicating portion.
[0128] Here, the second filling portion 62 includes a communicating
filling portion (in the case of this exemplary embodiment,
intersecting filling portion 69, 70) that extends toward the first
filling portion 61 and communicates to the first filling portion
61.
[0129] More specifically, the filling portion 60 includes the first
portion (in the case of this exemplary embodiment, the opposing
portion 67a), the second portion (in the case of this exemplary
embodiment, the intersecting filling portion 69), and a third
portion (in the case of this exemplary embodiment, the upward
extending portion 67b), which are intersected with each other and
communicate to each other at the boundary portion between the body
portion 11 and the handle portion 12.
[0130] The first portion is formed in the body portion 11. The
second portion is formed in the handle portion 12. The third
portion is formed in the body portion 11 or the handle portion 12.
In the case of this exemplary embodiment, the third portion (upward
extending portion 67b) is formed in the body portion 11. That is,
in the case of this exemplary embodiment, the first filling portion
61 includes the first portion and the third portion, and the second
filling portion 62 includes the second portion.
[0131] In addition, the local attached portion 29 is formed so as
to locally reduce the cross-sectional area of the filling portion
60 that is perpendicular to a direction in which the communicating
filling portion extends. The local attached portion 29 is formed at
the communicating portion between the communicating filling portion
(intersecting filling portion 69) and the first filling portion 61,
that is, at the communicating portion between the first filling
portion 61 and the second filling portion 62 (see FIGS. 1, 2, 3, 7,
9, and 10).
[0132] This structure makes it possible to appropriately secure a
bending deformation property of the container main body 20 at the
boundary portion between the body portion 11 and the handle portion
12. In other words, the cross-sectional area of the filling portion
may increase at the communicating portion where plural filling
portions that extend in different directions intersect each other.
In a case where the local attached portion 29 is not provided, the
cross-sectional area of the filling portion has a size as indicated
by the imaginary line 600 in FIG. 3. As opposed to this, in the
case of the present exemplary embodiment, the local attached
portion 29 is formed near the communicating portion. This makes it
possible to locally reduce the cross-sectional area of the filling
portion at this communicating portion as indicated by the solid
line in FIG. 3, which improves the bending deformation property of
this communicating portion. Thus, the handle portion 12 does not
deform in an unexpected direction with respect to the body portion
11, and it is possible to easily achieve a structure in which it
bends in a desired direction. That is, it is possible to achieve a
structure in which the handle portion 12 straightly extends from
the body portion 11 toward the lateral direction (in the rightward
direction), for example, as illustrated in FIG. 2 and FIGS. 4 to
6.
[0133] More specifically, the local attached portion 29 is formed
at the intersecting portion between the first portion, the second
portion, and the third portion (intersecting portion between the
opposing portion 67a, the intersecting filling portion 69, and the
upward extending portion 67b). In other words, with the local
attached portion 29 being formed at the intersecting portion
between filling portions that extend in three directions, the
bending deformation property of this intersecting portion
improves.
[0134] The local attached portion 29 is formed in the non-attached
region 24 in an island manner, as illustrated in FIGS. 1, 9, and
10. The "local attached portion 29 is formed in the non-attached
region 24 in an island manner" means that the local attached
portion 29 is formed in the non-attached region 24 at a position
that is spaced apart from a portion of the attached portion that
surrounds the non-attached region 24, this attached portion being
an attached portion between the outer film 22 and the inner film 23
of the main-body forming sheet member 21.
[0135] With the local attached portion 29 being formed in the
non-attached region 24 in an island manner, communicating portions
111 and 112 are each formed on corresponding one of both sides with
the local attached portion 29 being disposed therebetween, and near
the communicating portion between the first filling portion 61 and
the communicating filling portion of the second filling portion 62,
that is, at the intersecting portion between the first portion
(opposing portion 67a), the second portion (intersecting filling
portion 69), and the third portion (upward extending portion 67b)
of the filling portion 60, as illustrated in FIGS. 1, 3, and 7. In
the case of this exemplary embodiment, the communicating portions
111 and 112 are portions where the second portion (intersecting
filling portion 69) communicates to the first portion and the third
portion (the opposing portion 67a and the upward extending portion
67b). However, the present invention is not limited to this
example. The communicating portions 111 and 112 may be portions
where any portions from among the first portion to the third
portion are combined, and communicate to each other.
[0136] With the local attached portion 29 being formed in an island
manner, it is possible to stably obtain the handle portion 12
having increased mechanical strength, as compared with a mode
(described later) in which the local attached portion 29 is formed
in a semi-island manner as illustrated in FIG. 17. In addition, the
filling portion 60 exists around the local attached portion 29.
Thus, in a case where the local attached portion 29 is formed on
both of the forward side and the back surface side of the handle
portion 12, it is possible to achieve the handle portion 12 having
increased mechanical strength regardless of whether the position of
the local attached portion 29 on the forward side of the container
100 and the position of the local attached portion 29 on the back
surface side are equal to each other or these positions are
different from each other. This makes it possible to prevent the
handle portion 12 from being twisted with respect to the body
portion 11.
[0137] With the communicating portions 111 and 112 being formed on
both sides with the local attached portion 29 being disposed
therebetween, this configuration allows a portion of the filling
portion 60 where the local attached portion 29 is formed, to have a
mechanical strength favorably balanced between both end portions
with the local attached portion 29 being disposed therebetween.
[0138] The shape of the local attached portion 29 is not
specifically limited. However, in the case of this exemplary
embodiment, the local attached portion 29 is formed into a circular
shape.
[0139] In addition, the "communicating portion between the first
filling portion 61 and the communicating filling portion of the
second filling portion 62" means the BL indicated by the imaginary
line in FIG. 7 and near the BL.
[0140] In the case of this exemplary embodiment, the local attached
portion 29 is disposed at a position along the boundary line BL
(FIG. 7) between the second portion (intersecting filling portion
69) and a merging region 115 (FIG. 7) between the first portion
(opposing portion 67a) and the third portion (upward extending
portion 67b). In other words, the local attached portion 29 is
disposed near the boundary line BL. The distance between the
position of the local attached portion 29 and the boundary line BL
is preferably equal to or less than 30 mm, and is more preferably
equal to or less than 15 mm.
[0141] This configuration makes it possible to appropriately secure
a bending deformation property of a portion of the container main
body 20 along the boundary line BL (or a portion in the vicinity
thereof), which makes it possible to achieve a structure in which
the handle portion 12 is bent toward a desired direction with
respect to the body portion 11. In addition, it is possible to
sufficiently secure the continuity between the first portion and
the third portion, which makes it possible to sufficiently secure
the mechanical property of a portion of the container main body 20
where the first portion and the third portion are formed.
[0142] In the case of this exemplary embodiment, the container 100
includes an external-air introducing portion 73 (FIGS. 1 and 8)
that allows external air to be introduced between an external
surface of the inner bag 40 (inner container) and an inner surface
of the container main body 20.
[0143] As illustrated in FIG. 8, the external-air introducing
portion 73 is comprised, for example, of a space between a portion
of the body portion 11 that faces the penetrating portion 19, and a
portion of the inner bag 40 that faces the penetrating portion 19.
However, the external-air introducing portion 73 may be formed at
any position, provided that it allows external air to be
introduced.
[0144] With the container 100 including the external-air
introducing portion 73, it is possible to easily make the inner bag
40 shrink independently of the container main body 20 at the time
of discharging the contents 18 from the container 100. This
improves discharging property for the contents 18 from the
container 100.
[0145] As illustrated in FIG. 2, the container 100 is configured to
include the main-body forming sheet member 21 that constitutes the
container main body 20, and the inner-bag forming sheet member 41
that constitutes the inner bag 40.
[0146] As illustrated in FIG. 9, the main-body forming sheet member
21 is configured by stacking and attaching, to each other, the
outer film 22 that constitutes the external surface side of the
container main body 20 and the inner film 23 that constitutes the
inner surface side of the container main body 20. That is, as one
example, in the case of this exemplary embodiment, the main-body
forming sheet member 21 includes two layers of film layers
including the outer film 22 and the inner film 23. However, the
present invention is not limited to this example. The main-body
forming sheet member 21 may have a film layer other than the outer
film 22 and the inner film 23.
[0147] The non-attached region 24 in which the outer film 22 and
the inner film 23 are partially not attached to each other is
formed in the main-body forming sheet member 21. For example, a
non-attaching treatment is partially applied to a surface of either
one of or both of the outer film 22 and the inner film 23, this
surface facing a surface of the other one. The non-attaching
treatment can be easily formed by applying a non-attaching agent
(so-called adhesion inhibiting agent) to bring an adhesion
inhibiting state. For the adhesion inhibiting agent, any agent can
be used, provided that it can prevent the outer film 22 and the
inner film 23 from being attached together. For the adhesion
inhibiting agent, it is possible to preferably use, for example,
printing ink, medium ink, ink dedicated to adhesion inhibition, or
the like used in offset printing, flexography, and letterpress
printing (relief printing). In addition, it is also possible to
preferably use thermosetting ink or UV curable ink.
[0148] The range in which the non-attaching treatment is applied is
to be the non-attached region 24. A filler is put into the
non-attached region 24 to form the filling portion 60.
[0149] The filling portion 60 is not necessarily formed in the
entire non-attached region 24, and may be formed in a portion of
the non-attached region 24.
[0150] It is preferable that the entire surface of the inner film
23 except for the non-attached region 24 has an attached portion
that is attached to one surface of the outer film 22, and the
present exemplary embodiment employs this configuration.
[0151] As for a method of attaching the outer film 22 and the inner
film 23 together, it is possible to use heat sealing, ultrasonic
sealing, attaching with adhesive, or the like, as an example.
[0152] In addition, for example, the local attached portion 29 in
which the outer film 22 and the inner film 23 are locally attached
to each other is formed at a state in which the main-body forming
sheet member 21 is formed. Furthermore, as for a method of forming
the local attached portion 29, it is possible to use a method that
is effective in attaching a very small region such as ultrasonic
spot welding, adhesive sealing, and the like, in addition to the
method identical to the attaching of the outer film 22 and the
inner film 23 described above.
[0153] The outer film 22 and the inner film 23 also have a
multilayer structure. In addition, the inner-bag forming sheet
member 41 also has a multilayer structure.
[0154] As one example, the outer film 22 has a four-layer structure
formed by stacking a first layer, a second layer, a third layer,
and a fourth layer in this order.
[0155] Of these layers, the first layer includes, for example,
polyethylene terephthalate (PET) or oriented nylon (ONy). The main
function of the first layer is to provide the container main body
20 with a feeling of gloss and printability, and also to provide
the container main body 20 with rigidity.
[0156] The second layer is a layer of transparent deposition PET
including polyethylene terephthalate obtained through vapor
deposition of silica and/or alumina on a surface of this second
layer on the first layer side. The main function of the second
layer is to provide the container main body 20 with a gas barrier
property.
[0157] The third layer includes, for example, oriented nylon. The
main function of the third layer is to provide the container main
body 20 with a pinhole resistance.
[0158] The fourth layer includes, for example, linear low-density
polyethylene (LLDPE). The main function of the fourth layer is to
achieve a heat seal property with the inner film 23, a heat seal
property between the outer film 22, and a heat seal property with
the inner-bag forming sheet member 41.
[0159] As for the layer structure of the inner film 23, it is
possible to employ a layer structure similar to the outer film 22.
However, the material of each of the layers that constitute the
outer film 22 and the inner film 23 is not limited to the examples
described above. In addition, the inner film 23 may have a layer
structure differing from that of the outer film 22.
[0160] The main-body forming sheet member 21 includes, for example:
a first sheet portion 31 that is a portion that constitutes the
first main surface portion 20a; a second sheet portion 32 that is a
portion that constitutes the second main surface portion 20b; a
bottom-gusset forming sheet portion 38 that is a portion that
constitutes the bottom gusset portion 13; a first handle forming
sheet portion 33 that is a portion that constitutes the front
surface side of the handle portion 12; a second handle forming
sheet portion 34 that is a portion that constitutes the back
surface side of the handle portion 12; a top-gusset forming sheet
portion 39 that is a portion that constitutes the top gusset
portion 14; and a tube-shaped extending portion 25. For example,
the extending portion 25 extends outward from the second handle
forming sheet portion 34.
[0161] A penetrating portion 35 that corresponds to the penetrating
portion 19 is formed between the first sheet portion 31 and the
first handle forming sheet portion 33 and is also formed between
the second sheet portion 32 and the second handle forming sheet
portion 34.
[0162] An insert hole 21a into which the outlet cylinder portion
15a of the spout 15 is inserted is formed in the top-gusset forming
sheet portion 39.
[0163] A portion of the main-body forming sheet member 21 that
excludes the top-gusset forming sheet portion 39 and the extending
portion 25 is referred to as a sheet main body portion 28.
[0164] In the case of this exemplary embodiment, the non-attached
region 24 is formed into a shape that corresponds to the shape of
the filling portion 60 of the container 100. For example, the
non-attached region 24 communicates to the outside only through an
open end 24a at the top end of the extending portion 25.
[0165] For example, the peripheral edge portion of a portion of the
outer film 22 that constitutes the sheet main body portion 28 is an
exposing portion 26 that is not covered with the inner film 23,
except for a portion of the first sheet portion 31 that is adjacent
to the penetrating portion 35, a portion of the second sheet
portion 32 that is adjacent to the penetrating portion 35, and a
portion of the second handle forming sheet portion 34 that
corresponds to a base end of the extending portion 25.
[0166] In the case of this exemplary embodiment, the whole of the
top-gusset forming sheet portion 39 is comprised, for example, of
the outer film 22, and does not include the inner film 23. Thus,
the whole of a portion of the outer film 22 that constitutes the
top-gusset forming sheet portion 39 is the exposing portion 26 that
is not covered with the inner film 23. However, the present
invention is not limited to this. The top-gusset forming sheet
portion 39 may also have a stacked structure of the outer film 22
and the inner film 23.
[0167] In the extending portion 25, the external line of the outer
film 22 and the external line of the inner film 23 align with each
other in plan view.
[0168] The exposing portion 26 serves as an attached portion
(inner-outer seal portion 43) between the main-body forming sheet
member 21 and the inner-bag forming sheet member 41 as well as an
attached portion (main-body sealing portion 48) between main-body
forming sheet member 21.
[0169] As one example, the inner-bag forming sheet member 41 that
constitutes the inner bag 40 has a three-layer structure configured
such that a first layer, a second layer, and a third layer are
stacked in this order.
[0170] Of these layers, the first layer includes, for example,
linear low-density polyethylene. The main function of the first
layer is to achieve a heat seal property (heat seal property with
the outer film 22) with the main-body forming sheet member 21.
[0171] The second layer is, for example, a layer of transparent
deposition oriented nylon including oriented nylon obtained through
vapor deposition of silica and/or alumina on a surface of this
second layer on the first layer side. The main function of the
second layer is to achieve a gas barrier property and a pinhole
resistance.
[0172] The third layer includes, for example, linear low-density
polyethylene. The main function of the third layer is to achieve a
heat seal property between inner-bag forming sheet member 41.
[0173] In addition, the layer structure of the inner-bag forming
sheet member 41 is not limited to the structure that has been
described here.
[0174] As illustrated in FIG. 10, the container forming sheet
member 51 is configured with the main-body forming sheet member 21
and the inner-bag forming sheet member 41 in a manner such that the
inner-bag forming sheet member 41 is stacked to the main-body
forming sheet member 21, and the exposing portion 26 of the outer
film 22 and the peripheral edge portion of the inner-bag forming
sheet member 41 are attached to each other to form the inner-outer
seal portion 43 (see FIG. 2).
[0175] In the case of this exemplary embodiment, the inner-bag
forming sheet member 41 includes a portion having the same shape as
the first sheet portion 31, a portion having the same shape as the
second sheet portion 32, a portion having the same shape as the
bottom-gusset forming sheet portion 38, and a portion having the
same shape as the top-gusset forming sheet portion 39. These
portions are layered with the first sheet portion 31, the second
sheet portion 32, the bottom-gusset forming sheet portion 38, and
the top-gusset forming sheet portion 39, respectively. The
inner-bag forming sheet member 41 further includes a portion having
a shape slightly smaller than the first handle forming sheet
portion 33 and a portion having a shape slightly smaller than the
second handle forming sheet portion 34. These portions are layered
with the first handle forming sheet portion 33 and the second
handle forming sheet portion 34, respectively.
[0176] A penetrating portion 45 having a size slightly larger than
that of the penetrating portion 35 is formed in a portion of the
inner-bag forming sheet member 41 that corresponds to each
penetrating portion 35.
[0177] In addition, in FIG. 10, a seal boundary line 41a of the
inner-bag forming sheet member 41 that constitutes the inner bag 40
is indicated by the solid line, for the purpose of convenience. The
seal boundary line 41a is a boundary line between a region where
the inner-bag forming sheet member 41 is attached (sealed) to each
other and the other region of the inner-bag forming sheet member 41
when the container 100 is formed by using the container forming
sheet member 51.
[0178] An insert hole 41b into which the outlet cylinder portion
15a of the spout 15 is inserted is formed in a portion of the
inner-bag forming sheet member 41 that overlaps with the top-gusset
forming sheet portion 39.
[0179] The plate shape portion 15b of the spout 15 is provided, for
example, on an inner surface of a portion of the inner-bag forming
sheet member 41 that overlaps with the top-gusset forming sheet
portion 39. The outlet cylinder portion 15a is caused to pass
through the insert hole 41b of the inner-bag forming sheet member
41 and the insert hole 21a of the top-gusset forming sheet portion
39, and protrudes toward the external surface side of these
sheets.
[0180] Peripheral edge portions of the container forming sheet
member 51 are attached to each other in a state where a folding
line 81, a folding line 82, and a folding line 84, illustrated in
FIG. 10, of the container forming sheet member 51 are folded as
valley fold, and a folding line 83 is folded as mountain fold. With
this operation, the container forming sheet member 51 is formed
into a bag shape with a two-layer structure. Here, the "valley
fold" means a way of folding in which it protrudes toward the side
going away from the viewer of FIG. 10, and the "mountain fold"
means a way of folding in which it protrudes toward the viewer of
FIG. 10.
[0181] That is, edge portions of the inner-bag forming sheet member
41 are attached to each other to form the inner-bag sealing portion
(see FIG. 2). Thus, using the inner-bag forming sheet member 41,
the inner bag 40 is formed. In addition, the outer film 22 is
attached to each other at a portion of the main-body forming sheet
member 21 that constitutes a bottom portion of the container main
body 20 and also at a portion that constitutes the handle portion
12, thereby forming the main-body sealing portion 48 (see FIG. 2).
This forms the main-body forming sheet member 21 in a bag
shape.
[0182] As for a method of attaching the inner-bag forming sheet
member 41 to each other, and a method of attaching the outer film
22 to each other, it is possible to use heat seal, ultrasonic
sealing, attaching with adhesive, or the like, as an example.
[0183] After the container forming sheet member 51 is formed into a
bag shape with two layers, a filler is inputted from the open end
24a of the extending portion 25 into the non-attached region 24,
and the non-attached region 24 is sealed, for example, at a portion
continuously connected to the root end side of the extending
portion 25. This makes it possible for the filler to be contained
in the non-attached region 24 to form the filling portion 60. In
addition, the pressure within the filling portion 60 is not
specifically limited. However, it is preferable that this pressure
is higher than atmospheric pressure, and for example, can be set to
be equal to or more than 10 kPa and equal to or less than 500 kPa
(gauge pressure). After formation of the filling portion 60, the
extending portion 25 is cut off, for example.
[0184] In this manner, it is possible to obtain the container 100.
However, the extending portion 25 may exist even in a state of the
container 100.
[0185] As described above, the body portion 11 includes the first
main surface portion 20a and the second main surface portion 20b,
which are opposed to each other with the containing portion 17
being disposed therebetween. The main-body forming sheet member 21
includes the first sheet portion 31 that constitutes the first main
surface portion 20a, the second sheet portion 32 that constitutes
the second main surface portion 20b, and the first handle forming
sheet portion 33 that continues with the first sheet portion 31.
The first handle forming sheet portion 33 constitutes the handle
portion 12. In addition, the first filling portion 61 (at least a
portion of the first filling portion 61) is formed in the first
sheet portion 31. The second filling portion 62 (at least a portion
of the second filling portion 62) is formed in the first handle
forming sheet portion 33.
[0186] More specifically, the main-body forming sheet member 21
further includes the second handle forming sheet portion 34 that
continues with the second sheet portion 32. The first handle
forming sheet portion 33 and the second handle forming sheet
portion 34 are caused to overlap with each other to form the handle
portion 12.
[0187] The first filling portion 61 (a portion of the first filling
portion 61) is also formed in the second sheet portion 32. The
second filling portion 62 (a portion of the second filling portion
62) is also formed in the second handle forming sheet portion
34.
[0188] After the container 100 is manufactured, the contents 18 are
inputted through the outlet cylinder portion 15a of the spout 15
into the containing portion 17. After this, the cap 16 is mounted
on the spout 15. This makes it possible to obtain the
contents-packed container 200 in which the contents 18 are
contained in the containing portion 17.
[0189] The container main body 20 includes a first communicating
portion in which the first filling portion 61 formed in the first
sheet portion 31 and the communicating filling portion of the
second filling portion 62 formed in the first handle forming sheet
portion 33 communicate to each other, and also includes a second
communicating portion in which the first filling portion 61 formed
in the second sheet portion 32 and the communicating filling
portion of the second filling portion 62 formed in the second
handle forming sheet portion 34 communicate to each other.
[0190] In addition, the first communicating portion and the second
communicating portion overlap with each other in a direction in
which the first main surface portion 20a and the second main
surface portion 20b are opposed to each other.
[0191] In other words, the container 100 according to the present
exemplary embodiment has a structure in which the first
communicating portion and the second communicating portion, which
are communicating portions comprised of filling portions that
extend in different directions from each other, overlap with each
other in the direction in which the first main surface portion 20a
and the second main surface portion 20b are opposed to each other.
Thus, in a portion where the first communicating portion and the
second communicating portion overlap with each other, the filling
portions having a large cross-sectional area are locally
concentrated, and a force resulting from the filling portion on the
front surface side and the filling portion on the back surface side
pushing against each other in the front-rear direction tends to be
strengthened locally.
[0192] However, as described above, the local attached portion 29
is formed near the communicating portion between filling portions
that extend in different directions from each other. This enables
the cross-sectional area of the filling portions to be reduced
locally at the communicating portions, thereby appropriately
suppressing the force resulting from the filling portion on the
front surface side and the filling portion on the back surface side
pushing against each other in the front-rear direction. This makes
it possible to easily achieve a structure in which the handle
portion 12 is bent toward a desired direction with respect to the
body portion 11, as described above.
[0193] Furthermore, the present invention is not limited to this
example. The second filling portion 62 may not be formed in the
second handle forming sheet portion 34. In addition, the handle
portion 12 may be comprised only of the first handle forming sheet
portion 33 (configuration in which the second handle forming sheet
portion 34 is not included).
[0194] In the case of this exemplary embodiment, the local attached
portion 29 is formed in each of the first sheet portion 31 and the
second sheet portion 32 (see FIGS. 3, 9, and 10). More
specifically, the local attached portion 29 is formed near the
first communicating portion and is also formed near the second
communicating portion. This makes it possible to achieve the
filling portions having rigidity favorably balanced between the
first communicating portion and the second communicating portion
(that is, between the front surface side and the back surface side
of the container main body 20). Thus, it is possible to more easily
achieve a structure in which the handle portion 12 straightly
extends toward the lateral direction (the rightward direction) from
the body portion 11.
[0195] In the case of this exemplary embodiment, the local attached
portion 29 of the first sheet portion 31 and the local attached
portion 29 of the second sheet portion 32 each have a shape equal
to each other. However, the present invention is not limited to
this example. The local attached portion 29 of the first sheet
portion 31 and the local attached portion 29 of the second sheet
portion 32 may have different shapes.
[0196] In the case of this exemplary embodiment, the local attached
portion 29 of the first sheet portion 31 and the local attached
portion 29 of the second sheet portion 32 overlap with each other
in the front-rear direction. In other words, when the container 100
is viewed from a direction in which the first main surface portion
20a and the second main surface portion 20b are opposed to each
other, the local attached portion 29 of the first sheet portion 31
and the local attached portion 29 of the second sheet portion 32 at
least partially overlap with each other.
[0197] Thus, in the first communicating portion and the second
communicating portion, it is possible to achieve favorable balance
in terms of rigidity of the filling portions, and it is possible to
more easily achieve a structure in which the handle portion 12
straightly extends toward the lateral direction (the rightward
direction) from the body portion 11.
[0198] More specifically, substantially the entire local attached
portion 29 of the first sheet portion 31 and substantially the
entire local attached portion 29 of the second sheet portion 32
overlap with each other in the front-rear direction.
[0199] Here, in the case of this exemplary embodiment, both end
portions of the second filling portion 62 each communicate to the
first filling portion 61, as described above. In addition, of the
communicating portions between the second filling portion 62 and
the first filling portion 61, the local attached portion 29 is
formed on the upper side, that is, near the communicating portion
disposed near the spout 15. In other words, the local attached
portion 29 is formed at the intersecting portion of the opposing
portion 67a, the intersecting filling portion 69, and the upward
extending portion 67b, rather than at the intersecting portion of
the opposing portion 67a, the intersecting filling portion 70, and
the sloped filling portion 65.
[0200] As described above, the container 100 according to the
present exemplary embodiment includes a discharge portion (spout
15) that allows the contents 18 to be discharged from the
containing portion 17, as illustrated in FIG. 1. The filling
portion 60 includes the first filling portion 61 disposed in the
body portion 11 and including the first portion (opposing portion
67a), and also includes the second filling portion 62 disposed in
the handle portion 12 and including the second portion
(intersecting filling portion 69). The second filling portion 62 is
formed into a semi-annular shape. One end portion and the other end
portion of the second filling portion 62 each have the
communicating filling portion (intersecting filling portion 69, 70)
that communicates to the first filling portion 61. The local
attached portion 29 is formed so as to locally reduce the
cross-sectional area of the filling portion 60 that is
perpendicular to the direction in which the communicating filling
portion (intersecting filling portion 69) extends, the formation of
the local attached portion 29 being at the communicating portion
that corresponds to the end portion disposed closer to the
discharge portion from among the one end portion and the other end
portion of the second filling portion 62.
[0201] This makes it possible to achieve a structure in which a
portion of the handle portion 12 that is close to the discharge
portion (spout 15) is bent toward a desired direction with respect
to the body portion 11 (structure that straightly extends toward
the lateral direction (rightward direction) from the body portion
11). Thus, it is possible to suppress wobbling of the body portion
11 relative to the handle portion 12 when a user grips the handle
portion 12 to hold the container 100, and discharge the contents 18
from the discharge portion. This makes it possible to more easily
discharge the contents 18.
[0202] Here, as can be understood from the description above, the
body portion 11 includes the bottom portion (bottom gusset portion
13). The discharge portion (spout 15) is disposed on a side
opposite to the bottom portion, that is, disposed in an upper
portion of the body portion 11. The handle portion 12 protrudes
toward the lateral direction from the body portion 11. The one end
portion of the second filling portion 62 is disposed higher than
the other end portion of the second filling portion 62. The local
attached portion 29 is formed at the communicating portion
corresponding to the one end portion of the second filling portion
62 so as to locally reduce the cross-sectional area of the filling
portion 60 perpendicular to the direction in which the
communicating filling portion (intersecting filling portion 69)
extends.
[0203] With the body portion 11 including the bottom gusset portion
13, the lower portion of the sloped filling portion 65 of the body
portion 11 is configured such that the distance between the sloped
filling portion 65 formed in the first main surface portion 20a and
the sloped filling portion 65 formed in the second main surface
portion 20b gradually increases toward the downward, as illustrated
in FIG. 6.
[0204] Thus, there is a tendency that the pushing force against
each other in the front-rear direction between the communicating
portion of the opposing portion 67a, the intersecting filling
portion 70, and the sloped filling portion 65 in the first main
surface portion 20a and the communicating portion of the opposing
portion 67a, the intersecting filling portion 70, and the sloped
filling portion 65 in the second main surface portion 20b is lower
than the pushing force against each other in the front-rear
direction between the communicating portion of the opposing portion
67a, the intersecting filling portion 69, and the upward extending
portion 67b in the first main surface portion 20a and the
communicating portion of the opposing portion 67a, the intersecting
filling portion 69, and the upward extending portion 67b in the
second main surface portion 20b.
[0205] In addition, with the local attached portion 29 being formed
near the communicating portion on the upper side (the intersecting
portion of the opposing portion 67a, the intersecting filling
portion 69, and the upward extending portion 67b), it is possible
to more easily manipulate the spout 15 in a targeted direction at
the time of gripping the handle portion 12 to hold the container
100 and discharge the contents 18 from the spout 15.
[0206] Thus, from the viewpoint of sufficiently obtaining the
structural strength at the boundary portion between the body
portion 11 and the handle portion 12, in a case where the local
attached portion 29 is formed in only either one of the
communicating portion on the upper side (intersecting portion of
the opposing portion 67a, the intersecting filling portion 69, and
the upward extending portion 67b) and the communicating portion on
the lower side (intersecting portion of the opposing portion 67a,
the intersecting filling portion 70, and the sloped filling portion
65), it can be said that it is rational to form the local attached
portion 29 only near the communicating portion on the upper side.
In particular, in a case where the container 100 has a large
capacity size, the local attached portion 29 is formed only at the
communicating portion on the upper side, and the local attached
portion 29 is not formed at the communicating portion on the lower
side. This provides the container 100 with excellent
holdability.
[0207] However, the present invention is not limited to this
example. For example, in a case where the container does not have a
large capacity size, the local attached portion 29 may be formed in
both of the intersecting portion on the upper side and the
intersecting portion on the lower side.
[0208] FIG. 11 is an enlarged view schematically illustrating a
portion A illustrated in FIG. 9.
[0209] As illustrated in FIG. 11, narrow portions 36 and 37
(portions of inflection points that are recessed inwardly) are
formed locally on the edge (external line) of a portion of the
handle portion 12 that forms the outer peripheral side from among
portions of the outer film 22 and the inner film 23 that constitute
the second handle forming sheet portion 34.
[0210] With such narrow portions 36 and 37 being formed in the
outer film 22 and the inner film 23, it is possible to easily form
the narrow portion 72, as illustrated in FIG. 1, due to an effect
of distortion occurring when the second filling portion 62 of the
handle portion 12 expands in a three-dimensional manner.
[0211] Furthermore, the width size W1 of the exposing portion 26
that is to be the handle-portion sealing portion 48a of the handle
portion 12 on the outer peripheral side is larger than the width
size W2 of the exposing portion 26 that is to be the handle-portion
sealing portion 48b of the handle portion 12 on the inner
peripheral side, as illustrated in FIG. 11.
[0212] This makes it possible to achieve a structure in which the
width size of the handle-portion sealing portion 48a of the handle
portion 12 on the outer peripheral side is larger than the width
size of the handle-portion sealing portion 48b of the handle
portion 12 on the inner peripheral side, as described above.
Second Exemplary Embodiment
[0213] Next, a second exemplary embodiment will be described with
reference to FIG. 12.
[0214] A container 100 according to the present exemplary
embodiment differs from the container 100 according to the first
exemplary embodiment described above in terms of the point
described below. In other points, the container 100 according to
the present exemplary embodiment is configured in a manner similar
to the container 100 according to the first exemplary embodiment
described above.
[0215] The first exemplary embodiment described above gives an
example in which the second filling portion 62 is formed
continuously over both end portions of this second filling portion
62. However, in the case of this exemplary embodiment, a second
filling portion 62 is formed in a partially discontinuous manner
between both end of this second filling portion 62 as illustrated
in FIG. 12.
[0216] That is, a discontinuity portion 74 configured by attaching
the outer film 22 and the inner film 23 of the main-body forming
sheet member 21 to each other is formed in the handle portion 12.
The second filling portion 62 is partitioned by this discontinuity
portion 74.
[0217] In the case of this exemplary embodiment, the discontinuity
portion 74 is formed in the vertically extending filling portion
68. More specifically, the discontinuity portion 74 is disposed at
a central portion of the vertically extending filling portion 68 in
the vertical direction. Thus, the vertically extending filling
portion 68 is divided into two portions in the vertical
direction.
[0218] The discontinuity portion 74 traverses the vertically
extending filling portion 68 in a direction perpendicular to the
longitudinal direction of this vertically extending filling portion
68. As illustrated in FIG. 12 as an example, it is preferable that
the dimension of the discontinuity portion 74 in the longitudinal
direction of the vertically extending filling portion 68 is smaller
than the dimension of the discontinuity portion 74 in a direction
perpendicular to the longitudinal direction of the vertically
extending filling portion 68.
[0219] A portion of the handle portion 12 where the discontinuity
portion 74 is formed is a structurally weak portion as compared
with a portion of the handle portion 12 where the second filling
portion 62 is formed. With this configuration, the portion of the
handle portion 12 where the discontinuity portion 74 is formed
deforms to absorb the distortion occurring when the second filling
portion 62 of the handle portion 12 expands in a three-dimensional
manner. Thus, a narrow portion 72 where the handle portion 12 is
narrowed is formed above and below the discontinuity portion
74.
[0220] More specifically, at the narrow portion 72, the handle
portion 12 is slightly bent toward the inner direction of the
penetrating portion 19.
[0221] That is, in the case of this exemplary embodiment, a narrow
portion or a bent portion is formed at an intermediate portion
between both ends of the second filling portion 62.
[0222] With this configuration, in the case of this exemplary
embodiment, the handle-portion sealing portion 48a leans forward or
backward, and the handle-portion sealing portion 48b also leans
backward. This provides the handle portion 12 with a softer
texture.
[0223] It is preferable that the discontinuity portion 74 on the
front surface side of the handle portion 12 and the discontinuity
portion 74 on the back surface side (the discontinuity portion 74
of the first handle forming sheet portion 33 and the discontinuity
portion 74 of the second handle forming sheet portion 34) are
disposed at positions that overlap with each other in the
front-rear direction.
Third Exemplary Embodiment
[0224] Next, a third exemplary embodiment will be described with
reference to FIG. 13.
[0225] The container 100 according to the present exemplary
embodiment differs from the container 100 according to the second
exemplary embodiment described above in terms of the point
described below. In other points, the container 100 according to
the present exemplary embodiment is configured in a manner similar
to the container 100 according to the second exemplary embodiment
described above.
[0226] In the case of this exemplary embodiment, the discontinuity
portion 74 is disposed between a left end portion of the
intersecting filling portion 70 and a boundary portion between the
body-portion vertically extending filling portion 67 and the sloped
filling portion 65. Thus, the second filling portion 62
communicates to the first filling portion 61 only at one end
portion, and does not communicate to the first filling portion 61
at the other end portion.
[0227] In the case of this exemplary embodiment, a portion of the
handle portion 12 where the discontinuity portion 74 is formed
deforms to absorb the distortion occurring when the second filling
portion 62 of the handle portion 12 expands in a three-dimensional
manner.
[0228] In the case of this exemplary embodiment, the first filling
portion 61 and the second filling portion 62 are communicate with
each other at a left end portion of the intersecting filling
portion 69 and the boundary portion between the opposing portion
67a and the upward extending portion 67b. This achieves favorable
holdability of the container 100 for a user.
[0229] The discontinuity portion 74 is not limited to that disposed
at the position as described in the present exemplary embodiment.
For example, the discontinuity portion 74 may be disposed between
the left end portion of the intersecting filling portion 69 and the
boundary portion between the opposing portion 67a and the upward
extending portion 67b.
[0230] In addition, the left-right dimension of the discontinuity
portion 74 may be wider than that in the present exemplary
embodiment. For example, it may be possible to employ a
configuration in which the discontinuity portion 74 is formed over
the lower end portion of the vertically extending filling portion
68 and the boundary portion between the body-portion vertically
extending filling portion 67 and the sloped filling portion 65, and
the filling portion 60 does not include the intersecting filling
portion 70.
Fourth Exemplary Embodiment
[0231] Next, a fourth exemplary embodiment will be described with
reference to FIG. 14.
[0232] A container 100 according to the present exemplary
embodiment differs from the container 100 according to the first
exemplary embodiment described above in terms of the point
described below. In other points, the container 100 according to
the present exemplary embodiment is configured in a manner similar
to the container 100 according to the first exemplary embodiment
described above.
[0233] In the case of this exemplary embodiment, a slit 75 having a
shape such as a C-shape is formed in a region of the handle portion
12 that is surrounded by the second filling portion 62. A portion
of the handle portion 12 that is surrounded by the slit 75 is
folded over to form the penetrating portion 19. In other words, the
penetrating portion 19 is normally closed by a portion of the
handle portion 12 that is surrounded by the slit 75. By folding
this portion over, the penetrating portion 19 is made opened.
[0234] In addition, in the case of this exemplary embodiment, the
container 100 does not include the spout 15. Instead, the container
100 includes a to-be-torn portion 76. The to-be-torn portion 76 is
disposed at a position that acrossing the end portion of the
containing portion 17.
[0235] It is preferable to form a tear guiding line in the
to-be-torn portion 76. The tear guiding line is comprised, for
example, of a half-cut groove formed in at least one of the
container main body 20 and the inner bag 40, a perforation formed
in the container main body 20, or an easily openable film. However,
the tear guiding line may not be formed in the to-be-torn portion
76.
[0236] A user tears the container 100 along the to-be-torn portion
76, so that a discharge port (discharge portion) is formed in the
container 100.
[0237] In the case of this exemplary embodiment, the filling
portion 60 also includes the first filling portion 61 formed in the
body portion 11, and the second filling portion 62 formed in the
handle portion 12. The first filling portion 61 and the second
filling portion 62 communicate to each other. In the present
exemplary embodiment, unlike the container 100 according to the
first embodiment described above, the second filling portion 62
cannot be clearly distinguished into the vertically extending
filling portion 68 and intersecting filling portion 69, 70 which
have different extending directions. The second filling portion 62
extends in the vertical direction while curving convexly toward the
outward direction from the body portion 11. Even with such a shape,
the first filling portion 61 and the second filling portion 62
communicate to each other, which results in favorable holdability
of the container 100 for a user.
Fifth Exemplary Embodiment
[0238] Next, a fifth exemplary embodiment will be described with
reference to FIGS. 15 and 16.
[0239] A container 100 according to the present exemplary
embodiment differs from the container 100 according to the first
exemplary embodiment described above in terms of the point
described below. In other points, the container 100 according to
the present exemplary embodiment is configured in a manner similar
to the container 100 according to the second exemplary embodiment
described above.
[0240] In the case of this exemplary embodiment, as illustrated in
FIGS. 15 and 16, the local attached portion 29 of the first sheet
portion 31 and the local attached portion 29 of the second sheet
portion 32 are disposed at locations positionally shifted to each
other, when the container 100 is viewed from a direction
(front-rear direction) in which the first main surface portion 20a
and the second main surface portion 20b are opposed to each other.
This makes it possible to make the size balance between the
communicating portion 111 and the communicating portion 112 on the
front surface (first sheet portion 31) side and the size balance
between the communicating portion 111 and the communicating portion
112 on the back surface (second sheet portion 32) side can be made
different from each other, as illustrated in FIG. 16. Thus, it can
be expected that the force with which the communicating portion 111
and the communicating portion 112 on the front surface side and the
communicating portion 111 and the communicating portion 112 on the
back surface side press each other can be reduced, as compared with
the first exemplary embodiment, although it depends on conditions
such as a shape of the filling portion 60. This makes it possible
to expect an improvement of stability of a direction of the handle
portion 12 relative to the body portion 11.
[0241] In addition, in the case of this exemplary embodiment, both
of the local attached portions 29 are disposed at positions along
the boundary line BL (FIG. 15). Thus, with the present exemplary
embodiment, it is also possible to achieve a structure in which the
handle portion 12 is bent toward a desired direction relative to
the body portion 11, and also possible to sufficiently achieve a
mechanical strength of a portion of the container main body 20
where the first portion (opposing portion 67a) and the third
portion (upward extending portion 67b) are formed.
[0242] In the case of this exemplary embodiment, it is also
possible to provide the container 100 with a structure having
favorable holdability for a user, and also possible to easily
achieve a structure in which the handle portion 12 is bent toward a
desired direction relative to the body portion 11.
[0243] In the case of this exemplary embodiment, when the container
100 is viewed in the front-rear direction, the external line of the
local attached portion 29 of the first sheet portion 31 and the
external line of the local attached portion 29 of the second sheet
portion 32 overlap with each other. That is, when the container 100
is viewed in the direction in which the first main surface portion
20a and the second main surface portion 20b are opposed to each
other, at least a portion of the local attached portion 29 of the
first sheet portion 31 and at least a portion of the local attached
portion 29 of the second sheet portion 32 overlap with each other,
although the overlap is very small.
[0244] Thus, in the case of this exemplary embodiment, it is
possible to achieve the filling portions having rigidity favorably
balanced between the first communicating portion and the second
communicating portion, and it is also possible to more easily
achieve a structure in which the handle portion 12 straightly
extends toward the lateral direction (the rightward direction) from
the body portion 11.
Sixth Exemplary Embodiment
[0245] Next, a sixth exemplary embodiment will be described with
reference to FIGS. 17 and 18.
[0246] A container 100 according to the present exemplary
embodiment differs from the container 100 according to the
exemplary embodiments described above in terms of the points
described below. In other points, the container 100 according to
the present exemplary embodiment is configured in a manner similar
to the container 100 according to the exemplary embodiments
described above.
[0247] The exemplary embodiments described above give an example in
which the local attached portion 29 is formed in the non-attached
region 24 in an island manner. However, in the present exemplary
embodiment, the local attached portion 29 is formed continuously
with a portion of the main-body forming sheet member 21 that is an
attached portion between the outer film 22 and the inner film 23
and surrounds the non-attached region 24, as illustrated in FIGS.
17 and 18.
[0248] More specifically, the local attached portion 29 is formed
into a shape that protrudes toward the inside of the non-attached
region 24 from a portion of the main-body forming sheet member 21
that is an attached portion between the outer film 22 and the inner
film 23 and surrounds the non-attached region 24. In other words,
the local attached portion 29 is formed in a semi-island
manner.
[0249] In the example illustrated in FIGS. 17 and 18, the local
attached portion 29 of the first sheet portion 31 and the local
attached portion 29 of the second sheet portion 32 extend in
directions opposite to each other, and are disposed so as not to
overlap with each other in the front-rear direction.
[0250] However, in the case of this exemplary embodiment, the local
attached portion 29 of the first sheet portion 31 and the local
attached portion 29 of the second sheet portion 32 may overlap with
each other in the front-rear direction. In a case where these local
attached portions 29 overlap with each other in the front-rear
direction, the local attached portions 29 may entirely overlap with
each other (as in the first exemplary embodiment), or the local
attached portions 29 may partially overlap with each other (as in
the fifth exemplary embodiment).
[0251] Furthermore, in the case of this exemplary embodiment, both
of the local attached portions 29 are disposed at positions along
the boundary line BL (FIG. 17). Thus, with the present exemplary
embodiment, it is possible to locally reduce the cross-sectional
area of the filling portion 60 at the first communicating portion
and the second communicating portion. This makes it possible to
achieve a structure in which the handle portion 12 is bent toward a
desired direction with respect to the body portion 11, and also
possible to sufficiently obtain the mechanical strength at a
portion of the container main body 20 where the first portion
(opposing portion 67a) and the third portion (upward extending
portion 67b) are formed.
[0252] In the case of this exemplary embodiment, it is possible to
provide the container 100 having a structure with favorable
holdability for a user, and also possible to easily achieve a
structure in which the handle portion 12 is bent toward a desired
direction with respect to the body portion 11.
Seventh Exemplary Embodiment
[0253] Next, a seventh exemplary embodiment will be described with
reference to FIGS. 19A and 19B.
[0254] Each of the exemplary embodiments described above gives an
example in which the handle portion 12 protrudes toward the lateral
direction of the body portion 11. However, in the case of this
exemplary embodiment, the handle portion 12 protrudes upward of the
body portion 11. This allows a user to hold a container 100
according to the present exemplary embodiment as if it is a
handbag.
[0255] In the case of this exemplary embodiment, the filling
portion 60 includes the first filling portion 61 formed in the body
portion 11, and the second filling portion 62 formed in the handle
portion 12. In addition, the first filling portion 61 and the
second filling portion 62 communicate to each other.
[0256] Thus, it is possible to achieve favorable holdability of the
container 100 for a user.
[0257] As illustrated in FIG. 19B, for example, the container 100
includes two handle portions 12 that are formed independently of
each other, these handle portions 12 including, a first handle
portion 12 that protrudes upward from the first main surface
portion 20a, and a second handle portion 12 that protrudes upward
from the second main surface portion 20b. However, the present
invention is not limited to this example. The container 100 may
include only either the first handle portion 12 or the second
handle portion 12.
[0258] In the example in FIG. 19B, the handle portion 12 is formed
in the shape of an inverted U (in other words, semi-annular shape),
and both end portions of the handle portion 12 are each connected
to the upper end portion of the body portion 11.
[0259] The shape of the body portion 11 or the arrangement of the
filling portion 60 in the container 100 is not specifically
limited. However, for example, the body portion 11 is formed into a
substantially circular shape when viewed from the front surface
side. The filling portion 60 includes a first filling portion 61
that is formed along the peripheral edge portion of the first main
surface portion 20a (for example, formed into a circular ring
shape), and a first filling portion 61 that is formed along the
peripheral edge portion of the second main surface portion 20b (for
example, formed into a circular ring shape).
[0260] In addition, the second filling portion 62 on each handle
portion 12 is formed, for example, in the shape of an inverted U
(semi-annular shape) along each of the handle portions 12, and
communicates to the first filling portion 61 of the first main
surface portion 20a and the first filling portion 61 of the second
main surface portion 20b at both ends of each of the handle
portions 12.
[0261] In the case of this exemplary embodiment, the inner bag is
disposed, for example, only in the body portion 11.
[0262] The present invention is not limited to the above-described
exemplary embodiments and each modification example. Various modes
such as changes and modifications are included, provided that the
object of the present invention is achieved.
[0263] For example, the penetrating portion 19 may not be formed in
the container 100. That is, a portion of the handle portion 12 that
is surrounded by the second filling portion 62 may be closed, for
example, with a film made out of the main-body forming sheet member
21, the inner-bag forming sheet member 41, or the like.
[0264] Furthermore, the example in which the opposing portion 67a
is formed continuously over both ends of the second filling portion
62 has been described. However, the opposing portion 67a may be
discontinuous at a middle portion thereof.
[0265] Furthermore, in the example described above, the
handle-portion sealing portion 48a on the outer peripheral side and
the handle-portion sealing portion 48b on the inner peripheral side
are formed in the handle portion 12. However, a sealing portion
where the first handle forming sheet portion 33 and the second
handle forming sheet portion 34 are attached to each other may not
be formed in the handle portion 12.
[0266] Alternatively, a portion where the first handle forming
sheet portion 33 and the second handle forming sheet portion 34 are
not attached to each other may be provided at a middle portion of
the handle-portion sealing portion 48a on the outer peripheral
side. In addition, a portion where the first handle forming sheet
portion 33 and the second handle forming sheet portion 34 are not
attached to each other may be provided at a middle portion of the
handle-portion sealing portion 48a on the inner peripheral
side.
[0267] For example, the communicating region 49 may not be formed
in the handle portion 12. That is, the containing portion 17 may be
a closed region within the body portion 11. In addition, the inner
container (for example, inner bag 40) may not be disposed within
the handle portion 12 (the inner container may be disposed only
within the body portion 11).
[0268] Furthermore, the outer film 22 and the inner film 23 of the
main-body forming sheet member 21 may be formed so as to have the
same shape, and also may overlap with each other in a manner such
that the external lines of these films match each other.
[0269] In addition, the main-body forming sheet member 21 and the
inner-bag forming sheet member 41 may be formed so as to have the
same shape, and also may overlap with each other in a manner such
that the external lines of these members match each other.
[0270] In addition, an example in which the container 100 includes
the inner bag 40 (inner container) has been described above.
However, a container that does not include the inner bag 40 may be
possible.
[0271] In addition, in the exemplary embodiments described above,
the local attached portion 29 is disposed at a position along the
boundary line BL. However, the local attached portion 29 may be
disposed at a position spaced apart from the boundary line BL,
provided that the local attached portion 29 is disposed at the
communicating portion so as to locally reduce the cross-sectional
area of the filling portion 60.
[0272] The exemplary embodiments described above include the
following technical ideas.
