DESCRIPTION OF EMBODIMENTS

[0031] A spout pouch 10 according to an embodiment of the disclosure will be described below with reference to the accompanying drawings.

[0032] The spout pouch 10 accommodates a content liquid, such as a beverage or a liquid detergent, and is configured to spout the content liquid from a spout 80 attached to a side portion of a pouch main body 20 as illustrated in FIG. 1.

[0033] As illustrated in FIG. 1, the spout pouch 10 includes the pouch main body 20 formed into a bag shape by thermally sealing films 30, 40, 50, and 60 having flexibility to form a sealing portion for bag production, an inner side film 70 disposed inside the pouch main body 20, and the spout 80 attached to the pouch main body 20.

[0034] The pouch main body 20 is configured as a so-called lateral gusset-type pouch formed with gusset portions at both side portions and, as illustrated in FIG. 1 and FIG. 2, includes the front side film 30 and the rear side film 40 disposed facing each other in a front-rear direction X with a content liquid accommodating portion 21 interposed therebetween, the first gusset film 50 disposed between the front side film 30 and the rear side film 40 at one of pouch side portions and thermally sealed to the front side film 30 and the rear side film 40 by using a first side seal 22, and the second gusset film 60 disposed facing the first gusset film 50 in a front-back direction Z with the content liquid accommodating portion 21 interposed therebetween and thermally sealed to the front side film 30 and the rear side film 40 by using a second side seal 23 at the other of the pouch side portions.

[0035] Each of the films 30, 40, 50, 60, and 70 is formed as a resin film including a heat sealing layer on at least one surface thereof, and disposed such that the heat sealing layers face each other at positions where the films are thermally sealed to each other.

[0036] Note that, in FIG. 2 and the like, heat sealing regions of the films 30, 40, 50, 60, and 70 are indicated by shading.

[0037] As illustrated in FIG. 1 and FIG. 2, the pouch main body 20 includes the first side seal 22 formed by thermally sealing both sides of the first gusset film 50 in a lateral direction to the films 30 and 40, the second side seal 23 formed by thermally sealing both sides of the second gusset film 60 in the lateral direction to the films 30 and 40, a top seal 24 formed by fixing the films 30 and 40 between the first side seal 22 and the second side seal 23 in the front-back direction Z at a position corresponding to a top portion of the pouch main body 20 facing a bottom seal 25 with the content liquid accommodating portion 21 interposed therebetween, the bottom seal 25 fixing the films 30 and 40 at a position corresponding to a pouch bottom portion 20a of the pouch main body 20, and an intermediate seal 26 thermally sealing the films 30 and 40 and the inner side film 70. These seals 22 to 26 constitute a sealing portion for bag production.

[0038] When the inner side film 70 is provided as in the present embodiment, the top seal 24 and the bottom seal 25 include a portion where the films 30 and 40 are fixed by direct and thermal sealing between the films 30 and 40, and a portion where the inner side film 70 is interposed between the films 30 and 40 and the films 30 and 40 are fixed by thermal sealing between the films 30, 40 and 70.

[0039] If the spout pouch 10 is formed without providing the inner side film 70, the top seal 24 and the bottom seal 25 are constituted only by a portion where the films 30 and 40 are fixed to each other by direct and thermal sealing between the films 30 and 40.

[0040] As illustrated in FIG. 3, the first gusset film 50 includes a first front side sealing region 51, of the first side seal 22, thermally sealed to the front side film 30, a first rear side sealing region 52, of the first side seal 22, thermally sealed to the rear side film 40, and a non-sealing region 53 that is a region on an inner side of the first front side sealing region 51 and the front rear side sealing region 52.

[0041] As illustrated in FIG. 3, the first non-sealing region 53 includes a first front side outer edge 54 serving as a boundary with the first front side sealing region 51, and a first rear side outer edge 55 serving as a boundary with the first rear side sealing region 52.

[0042] The first gusset film 50 is formed in line symmetry (left-right symmetry) with respect to a virtual line extending in an up-down direction Y at a central portion of the first gusset film 50 in the front-rear direction X. In other words, the first front side outer edge 54 and the first rear side outer edge 55 are formed in line symmetry (left-right symmetry) with respect to the virtual line.

[0043] As illustrated in FIG. 3, the first front side outer edge 54 and the first rear side outer edge 55 respectively include first base edge portions 54a and 55a disposed spaced apart from each other in the front-rear direction X, first lower side inclined edge portions 54b and 55b respectively extending from lower ends of the first base edge portions 54a and 55a to a first lower end coupling portion 53a coupling lower ends of the first front side outer edge 54 and the first rear side outer edge 55 to each other, and first upper side inclined edge portions 54c and 55c respectively extending from upper ends of the first base edge portions 54a and 55a to an upper end coupling portion 53b coupling upper ends of the first front side outer edge 54 and the first rear side outer edge 55 to each other.

[0044] As illustrated in FIG. 3, the first base edge portions 54a and 55a are formed linearly extending in the up-down direction Y.

[0045] As illustrated in FIG. 3, the first lower side inclined edge portions 54b and 55b extend linearly so as to be inclined in the up-down direction Y inwardly in the front-rear direction X (at an inclination angle of 45 in the present embodiment) toward the lower side.

[0046] As illustrated in FIG. 3, the first upper side inclined edge portions 54c and 55c extend linearly so as to be inclined in the up-down direction Y inwardly in the front-rear direction X (at an inclination angle of 45 in the present embodiment) toward the upper side.

[0047] Further, as illustrated in FIG. 3, the first gusset film 50 includes a flange facing region 56 disposed facing a flange 81 of the spout 80. In the present embodiment, the flange facing region 56 is formed in an annular shape with an outer peripheral edge having a circular shape.

[0048] Further, the first gusset film 50 includes a spout-use through hole 57 having a circular shape. The spout-use through hole 57 is formed so as to penetrate in a film thickness direction, and is used for inserting a spouting tubular portion 82 of the spout 80 therethrough.

[0049] As illustrated in FIG. 4, the second gusset film 60 includes a second front side sealing region 61, of the second side seal 23, thermally sealed to the front side film 30, a second rear side sealing region 62, of the second side seal 23, thermally sealed to the rear side film 40, and a second non-sealing region 63 that is a region on an inner side of the second front side sealing region 61 and the second rear side sealing region 62.

[0050] As illustrated in FIG. 4, the second non-sealing region 63 includes a second front side outer edge 64 serving as a boundary with the second front side sealing region 61, and a second rear side outer edge 65 serving as a boundary with the second rear side sealing region 62.

[0051] The second gusset film 60 is formed in line symmetry (left-right symmetry) with respect to a virtual line extending in the up-down direction Y at a central portion of the second gusset film 60 in the front-rear direction X. In other words, the second front side outer edge 64 and the second rear side outer edge 65 are formed in line symmetry (left-right symmetry) with respect to the virtual line.

[0052] As illustrated in FIG. 4, the second front side outer edge 64 and the second rear side outer edge 65 respectively include second base edge portions 64a and 65a disposed spaced apart from each other in the front-rear direction X, second lower side inclined edge portions 64b and 65b extending from lower ends of the second base edge portions 64a and 65a to a second lower end coupling portion 63a coupling lower ends of the second front side outer edge 64 and the second rear side outer edge 65 to each other, and second upper side inclined edge portions 64c and 65c extending from upper ends of the second base edge portions 64a and 65a to a second upper end coupling portion 63b coupling upper ends of the second front side outer edge 64 and the second rear side outer edge 65 to each other.

[0053] As illustrated in FIG. 4, the second base edge portions 64a and 65a are formed linearly extending in the up-down direction Y.

[0054] As illustrated in FIG. 4, the second lower side inclined edge portions 64b and 65b extend linearly so as to be inclined in the up-down direction Y inwardly in the front-rear direction X (at an inclination angle of 45 in the present embodiment) toward the lower side.

[0055] As illustrated in FIG. 4, the second upper side inclined edge portions 64c and 65c extend linearly so as to be inclined in the up-down direction Y inwardly in the front-rear direction X toward the upper side.

[0056] Here, as illustrated in FIG. 5, the second upper end coupling portion 63b is formed at a position lower than that of the first upper end coupling portion 53b in the up-down direction Y.

[0057] Accordingly, as illustrated in FIG. 5, a top seal inner edge 24a of the top seal 24 facing the content liquid accommodating portion 21 side includes a portion downwardly inclined from the first upper end coupling portion 53b side toward the second upper end coupling portion 63b side (in the present embodiment, the top seal inner edge 24a is entirely inclined). The top seal inner edge 24a is formed to couple the first upper end coupling portion 53b and the second upper end coupling portion 63b to each other.

[0058] Thus, as illustrated in FIG. 7, when the spout pouch 10 is dropped with the top seal 24 side facing downward, and the top seal 24 (and the second side seal 23) is buckled due to the weight of the content liquid in the content liquid accommodating portion 21 at the time of collision with a floor surface or the like, a posture of the pouch main body 20 can be guided such that the first upper end coupling portion 53b (the first side seal 22 side, the right side in FIG. 7) attached with the spout 80 is positioned more upward than the second upper end coupling portion 63b (the second side seal 23 side, the left side in FIG. 7), resulting in suppressing collision of the spout 80 with the floor surface or the like and suppressing breakage of the spout 80 and leakage of the content liquid caused by the breakage.

[0059] Note that, in the present embodiment, as illustrated in FIG. 5, the top seal inner edge 24a is constituted by a linear portion downwardly inclined from the first upper end coupling portion 53b side toward the second upper end coupling portion 63b side.

[0060] However, as long as in a specific aspect, the top seal inner edge 24a includes a portion downwardly inclined from the first upper end coupling portion 53b side to the second upper end coupling portion 63b side and couples the first upper end coupling portion 53b and the second upper end coupling portion 63b, the top seal inner edge 24a may be formed by combining two or more linear portions having different inclination angles as illustrated in FIG. 6A, may be constituted by one curved portion or two or more curved portions (portions extending in a curved line shape in a plan view in the front-back direction Z) as illustrated in FIG. 6B, or may be formed by combining one or more linear portions or one or more curved portions.

[0061] The spout 80 is formed of a synthetic resin or the like, is attached to the pouch main body 20 to function as a spouting outlet for the content liquid and, as illustrated in FIG. 1 and FIG. 5, and includes the flange 81 disposed facing the first gusset film 50, the spouting tubular portion 82 that extends perpendicularly to the flange 81 having a disk shape and that includes a spouting hole formed therein, and a cap 83 detachably attached to a tip end of the spouting tubular portion 82.

[0062] In the present embodiment, the flange 81 is formed as a portion having a disk shape (annular shape) with a through hole formed at a central portion thereof and an outer peripheral edge having a circular shape (flange outer peripheral edge), is disposed on an inner side of the pouch main body 20, and is at least partially fixed to an inner side surface of the first gusset film 50 by thermal sealing.

[0063] Note that FIG. 1 illustrates only the flange 81 of the spout 80 and, as illustrated in FIG. 5, most of the spout 80, such as the spouting tubular portion 82 and the cap 83, is disposed outside the pouch main body 20.

[0064] As illustrated in FIG. 3, at least a portion (all portion in the present embodiment) of the flange 81 (flange facing region 56) including a central portion of the flange 81 (flange facing region 56) is disposed facing a region between the first upper side inclined edge portion 54c of the first front side outer edge 54 and the first upper side inclined edge portion 55c of the first rear side outer edge 55.

[0065] Further, as illustrated in FIG. 3, the flange 81 (flange facing region 56) is disposed at a central portion of the first gusset film 50 in the front-rear direction X, and an interval between the first front side outer edge 54 and an outer edge of the flange 81 (flange facing region 56) and an interval between the first rear side outer edge 55 and the outer edge of the flange 81 (flange facing region 56) in the front-rear direction X are equal to each other.

[0066] As understood from FIG. 1, the region between the first upper side inclined edge portion 54c of the first front side outer edge 54 and the first upper side inclined edge portion 55c of the first rear side outer edge 55 to which the flange 81 is (at least partially) attached as described above is a portion inclined inwardly of the pouch main body 20 in the front-back direction Z toward the upper side in a view in the front-rear direction X in a state in which the spout pouch 10 is placed on a placement surface with the pouch bottom portion 20a facing downward. Therefore, in a state in which the spout pouch 10 is placed on the placement surface, as understood from FIG. 1 and FIG. 5, when viewed in the front-rear direction X, the spouting tubular portion 82 of the spout 80 attached to the region described above faces obliquely upward so as to extend obliquely with respect to the up-down direction Y (and the front-back direction Z), in other words, is inclined outwardly of the pouch main body 20 in the front-back direction Z toward the upper side.

[0067] The inner side film 70 is formed as a resin film having a rectangular shape (or substantially rectangular shape) and flexibility with a heat sealing layer provided on at least one side thereof and, as understood from FIG. 1 and FIG. 2, is disposed in the pouch main body 20 (content liquid accommodating portion 21) in a state of being folded in two, and a predetermined portion thereof is thermally sealed to the films 30 and 40.

[0068] As illustrated in FIG. 2, the inner side film 70 is formed with a plurality of film penetrating portions formed in hole shapes penetrating in the film thickness direction.

[0069] In addition, as illustrated in FIG. 1 and FIG. 5, the spout pouch 10 is provided with a grip-use film penetrating portion 27 through which a user passes his/her hand or finger to grip the pouch main body 20.

[0070] As illustrated in FIG. 1 and FIG. 2, the grip-use film penetrating portion 27 is formed so as to penetrate the films 30, 40, and 60 in the film thickness direction.

[0071] Note that FIG. 2 illustrates the grip-use film penetrating portion 27 being formed in a state in which the films 30, 40, and 60 are not thermally sealed to one another for convenience of technical understanding. However, in the present embodiment, the grip-use film penetrating portion 27 is formed by punching at a predetermined position after the films 30, 40, and 60 are thermally sealed to one another.

[0072] Here, as illustrated in FIG. 4, the second side seal 23 includes (two) second side sealing regions 23a at both sides in the front-rear direction positioned on sides of the second base edge portions 64a and 65a (on sides in the front-rear direction X), (two) second lower side sealing regions 23b at both sides in the front-rear direction positioned more downward than the second side sealing regions 23a, and (two) second upper side sealing regions 23c at both sides in the front-rear direction positioned more upward than the second side sealing regions 23a (in other words, a portion obtained by adding portions positioned on sides of the second upper side inclined edge portions 64c and 65c in the front-rear direction X and portions positioned more upward than the portions).

[0073] Then, as illustrated in FIG. 4 and FIG. 5, at least a part (in the present embodiment, the entirety) of the grip-use film penetrating portion 27 is formed in each of the second upper side sealing regions 23c at both sides in the front-rear direction.

[0074] Note that, of the (two) second upper side sealing regions 23c at both sides in the front-rear direction, one (the second upper side sealing region 23c illustrated on the left side in FIG. 4) is a region in which the films 30 and 60 are thermally sealed, and the other (the second upper side sealing region 23c illustrated on the right side in FIG. 4) is a region in which the films 40 and 60 are thermally sealed.

[0075] Here, as described above, by forming the grip-use film penetrating portion 27 in the second upper side sealing region 23c, as can be seen from FIG. 5, in a state where the spout pouch 10 is lifted up by utilizing the grip-use film penetrating portion 27, the spout pouch 10 can be guided to a posture in which the first side seal 22 side (left side in FIG. 5) attached with the spout 80 is lowered and the spouting tubular portion 82 of the spout 80 faces sideways. Accordingly, the content liquid from the spout 80 can be smoothly spouted.

[0076] As illustrated in FIG. 4 and FIG. 5, the pouch main body 20 includes (two in the present embodiment) grip-use piece portions 27a partitioned from a peripheral portion by the grip-use film penetrating portion 27. The grip-use piece portion 27a is provided to avoid a pain of a finger or the like of a user due to direct contact with the inner edge portion of the grip-use film penetrating portion 27 when the user passes his/her finger or hand through the hole formed by the grip-use film penetrating portion 27 to lift up the spout pouch 10, and a part of the outer edge thereof is coupled to the peripheral portion by a folding-use coupling portion 27b.

[0077] As illustrated in FIG. 4 and FIG. 5, the folding-use coupling portion 27b for the at least one (all in the present embodiment) grip-use piece portion 27a among the plurality of (two) grip-use piece portions 27a is formed in the second upper side sealing region 23c.

[0078] Further, the folding-use coupling portion 27b is formed in a portion, of the outer edge of the grip-use piece portion 27a, positioned outside the pouch. Thus, when the spout pouch 10 is lifted up by passing the user's finger or the like through the hole constituted by the grip-use film penetrating portion 27, the user's finger or the like comes into contact with the films 30, 40, and 60 that are folded in the vicinity of the folding-use coupling portion 27b, resulting in avoiding a pain of the user's finger or the like.

[0079] Additionally, as illustrated in FIG. 5, the inner side surfaces of the second upper side sealing regions 23c at both sides in the front-rear direction are fixed to each other at a fixing control portion 28 formed at a portion positioned on the outer side (outer edge side of the films 30, 40, and 60) of the pouch than the grip-use film penetrating portion 27, which prevents the second upper side sealing regions 23c at both sides in the front-rear direction from being separated from each other and allows the user's finger or the like to easily pass through the hole constituted by the grip-use film penetrating portion 27.

[0080] Here, as illustrated in FIG. 4, the two grip-use film penetrating portions 27 are formed in line symmetry (left-right symmetry) with respect to a virtual line extending along the up-down direction Y at the central portion of the second gusset film 60 in the front-rear direction X. Moreover, in a state where the second upper side sealing regions 23c at both sides in the front-rear direction are fixed at the fixing control portion 28, the positions and shapes of the grip-use film penetrating portions 27 at both sides in the front-rear direction overlap each other when viewed in the front-rear direction X as can be seen from FIG. 5. However, the two grip-use film penetrating portions 27 may be formed so as to have shapes and sizes different from each other without forming the two grip-use film penetrating portions 27 in left-right symmetry.

[0081] Further, as illustrated in FIG. 8, a second outer side non-sealing region 29 surrounded by the second upper side sealing region 23c of the second gusset film 60 may be provided, and the grip-use film penetrating portion 27 through which a user passes his/her hand or finger to grip the pouch main body 20 may be provided in the second outer side non-sealing region 29.

[0082] In this embodiment, most part of the grip-use film penetrating portion 27 is provided in the second outer side non-sealing region 29, and a part thereof is formed in the second upper side sealing region 23c.

[0083] As illustrated in FIG. 8, the pouch main body 20 is provided with the grip-use piece portion 27a partitioned from the peripheral portion by the grip-use film penetrating portion 27.

[0084] The grip-use piece portion 27a is provided to avoid a pain of a finger or the like of a user due to direct contact with the inner edge portion of the grip-use film penetrating portion 27 when the user passes his/her finger or hand through the hole formed by the grip-use film penetrating portion 27 to lift up the spout pouch 10, and a part of the outer edge thereof is coupled to the peripheral portion by the folding-use coupling portion 27b.

[0085] As illustrated in FIG. 8, the folding-use coupling portion 27b of the compound grip-use piece portion 27a is formed in the second upper side sealing region 23c.

[0086] Further, the folding-use coupling portion 27b is formed in a portion, of the outer edge of the grip-use piece portion 27a, positioned outside the pouch. Thus, when the spout pouch 10 is lifted up by passing the user's finger or the like through the hole constituted by the grip-use film penetrating portion 27, the user's finger or the like comes into contact with the films 30, 40, and 60 that are folded in the vicinity of the folding-use coupling portion 27b, resulting in avoiding a pain of the user's finger or the like.

[0087] Further, in the present embodiment, since the folding-use coupling portion 27b side of the grip-use piece portion 27a is disposed in the second upper side sealing region 23c and the tip end side thereof is disposed in the second outer side non-sealing region 29, as illustrated in FIGS. 9A to 9C, the portion disposed in the second outer non-sealing region 29 is easily folded, which makes it possible to further avoid a pain of the user's finger or the like.

[0088] In addition, since a part of the grip-use film penetrating portion 27 is disposed in the second upper side sealing region 23c, when the grip-use film penetrating portion 27 is punched after sealing, the cut piece is discharged in a state in which the cut piece is partially connected, and thus processing of the cut piece is facilitated.

[0089] Additionally, as illustrated in FIG. 5, the inner side surfaces of the second upper side sealing regions 23c at both sides in the front-rear direction are fixed to each other at the fixing control portion 28 formed at a portion positioned on the outer side (outer edge side of the films 30, 40, and 60) of the pouch than the grip-use film penetrating portion 27, which prevents the second upper side sealing regions 23c at both sides in the front-rear direction from being separated from each other and allows the user's finger or the like to easily pass through the hole constituted by the grip-use film penetrating portion 27.

[0090] Further, in the present embodiment, here, as can be seen from FIG. 8, the positions and shapes of the two grip-use film penetrating portions 27 at both sides in the front-rear direction overlap each other when viewed in the front-rear direction. However, the two grip-use film penetrating portions 27 may be formed so as to have shapes and sizes different from each other without forming the two grip-use film penetrating portions 27 in left-right symmetry.

[0091] Note that in the above-described embodiment, the second gusset film 60 is partially removed and the films 30 and 40 are thermally sealed to each other at the fixing control portion 28 so that the second upper side sealing regions 23c at both sides in the front-rear direction are fixed to each other at the fixing control portion 28. However, the second upper side sealing regions 23c may be fixed to each other at the fixing control portion 28 by any method such as a method using an adhesive or a molten resin.

[0092] The embodiments of the disclosure have been described in detail above, but the disclosure is not limited to the embodiments described above, and various design modifications can be made insofar as they do not depart from the scope of the claims of the disclosure. Further, the spout pouch 10 may be configured by any combination of configurations of the embodiments described above and modified examples, which will be described below.

[0093] For example, the spout pouch 10 may be accommodated and utilized in the outer case (not illustrated) during usage, during display, or during transport thereof, and the spout pouch 10 itself may be used, displayed, or transported, without being accommodated in the outer case (not illustrated).

[0094] Further, with respect to specific aspects of the respective films 30, 40, 50, 60, and 70, as long as each film includes a layer having a thermal sealing property, such as an olefin-based layer made of low density polyethylene or polypropylene or a polyester-based layer made of polyethylene terephthalate (PET), or the like on at least one of the surfaces thereof, a single film of the heat sealing layer may be used, or any desired layer may be layered to the heat sealing layer. Any material may be used as a material constituting the multilayer, and the multilayer may be formed as desired by layering a known polyester such as PET or polybutylene terephthalate (PBT), polyamide such as nylon, polyolefin such as polypropylene, or polyethylene, aluminum foil, or the like.

[0095] Further, in the embodiment described above, the pouch main body 20 has been described as being formed of four films, namely the films 30, 40, 50, and 60. However, a specific aspect of the pouch main body 20, such as the number of films constituting the pouch main body 20, is not limited to the above and, for example, a gusset film for the bottom portion may be separately provided at a position corresponding to the pouch bottom portion 20a.

[0096] Further, the inner side film 70 need not be provided.

[0097] Further, in the embodiment described above, the spout pouch 10 is configured as a large-capacity pouch having a volume of 2 to 5 L, and the spout 80 is configured as a large spout with an outer diameter of the flange 81 being 50 to 70 mm. However, the sizes of the spout pouch 10 and the spout 80 are not limited thereto and may be set as desired in accordance with the embodiment.

[0098] Further, in the embodiment described above, the first front side outer edge 54 and the first rear side outer edge 55 have been described as being formed in line symmetry (left-right symmetry) with respect to the virtual line extending in the up-down direction Y at the central portion of the first gusset film 50 in the front-rear direction X. However, the first front side outer edge 54 and the first rear side outer edge 55 may be formed not in left-right symmetry.

[0099] Further, similarly, in the embodiment described above, the second front side outer edge 64 and the second rear side outer edge 65 have been described as being formed in line symmetry (left-right symmetry) with respect to the virtual line extending in the up-down direction Y at the central portion of the second gusset film 60 in the front-rear direction X. However, the second front side outer edge 64 and the second rear side outer edge 65 may be formed not in left-right symmetry.

[0100] Further, in the embodiment described above, the flange 81 has been described as being formed in a disk shape with an outer peripheral edge having a circular shape. However, the specific shape of the flange 81 may be any shape such as a shape having an outer peripheral edge (flange outer peripheral edge) of a shape other than a circular shape, such as a rectangular shape or a polygonal shape.

[0101] Further, in the embodiment described above, the flange 81 has been described as being fixed to the inner side surface of the first gusset film 50. However, the flange 81 may be fixed to an outer side surface of the first gusset film 50.

[0102] Further, the flange 81 may be fixed to the first gusset film 50 by any method other than thermal sealing, such as adhesion.

[0103] Note that the terms top portion, bottom portion, side portion, and the like indicating up and down directions are used herein, but these terms do not limit the orientation of the placement of the spout pouch 10 during display, during transport, and the like. For example, the spout pouch 10 may be placed on the placement surface with the side portion or the top portion of the spout pouch 10 facing downward during display, during transport, and the like.

[0104] First, in the embodiment described above, the inclined edge portions 54b, 54c, 55c, 55b, 64b, 64c, 65c, and 65b have been described as being constituted by one linear portion extending in an inclined manner in the up-down direction Y, but the specific aspect of the inclined portions 54b, 54c, 55c, 55b, 64b, 64c, 65c, and 65b is not limited thereto, and each of the inclined portions 54b, 54c, 55c, 55b, 64b, 64c, 65c, and 65b may be constituted by at least one linear portion, at least one curved portion, or a combination thereof.

[0105] In addition, in the above-described embodiment, as illustrated in FIG. 2 and the like, the grip-use film penetrating portion 27 has been described as being formed in a hole shape (or a slit shape with a width) penetrating the films 30, 40, and 60 in the film thickness direction. However, the specific aspect of the grip-use film penetrating portion 27 is not limited thereto, and the grip-use film penetrating portion 27 may be formed as a slit having a cutout shape penetrating the films 30, 40, and 60 in the film thickness direction (the slit whose material is not removed and that does not have a width in a direction orthogonal to an extending direction thereof). Note that when the grip-use film penetrating portion 27 is formed in a hole shape (or a slit shape having a width), the visibility of the grip-use film penetrating portion 27 can be improved, and the position and the presence of the grip-use film penetrating portion 27 can be easily noticed.

[0106] In addition, in the above-described embodiment, as illustrated in FIG. 4 and FIG. 5, the entirety of the grip-use film penetrating portion 27 has been described as being formed in the second upper side sealing region 23c, and as illustrated in FIG. 8, the grip-use film penetrating portion 27 has been described as being formed in the second outer side non-sealing region 29. However, as illustrated in FIG. 6A, a part of the grip-use film penetrating portion 27 may be formed in a portion other than the second upper side sealing region 23c (that is, in the top seal 24 or the second side sealing region 23a).

[0107] Further, in the above-described embodiment, the grip-use film penetrating portion 27 has been described as being formed such that the grip-use piece portion 27a is formed in the pouch main body 20. However, a specific aspect of the grip-use film penetrating portion 27 is not limited to the above-described form, and the grip-use film penetrating portion 27 may be formed such that the grip-use piece portion 27a is not formed as illustrated in FIG. 6B.

[0108] Furthermore, in the above-described embodiment, as illustrated in FIG. 4, two grip-use piece portions 27a have been described as being formed for each grip-use film penetrating portion 27, but the number of grip-use piece portions 27a may be one or three or more for each grip-use film penetrating portion 27.
