Summary of the Invention
Problems to be Solved by the Invention
[0004] In the pouch container disclosed in Patent Document 1, gusset sheet portions are provided in both the upper and lower directions in the height direction. On the other hand, there is a need for a configuration in which a gusset sheet portion is provided only on one side in the height direction, and the end portions of the front sheet portion and the end portions of the back sheet portion are directly sealed on the other side in the height direction.
[0005] If no measures are taken in such cases, a gusset sheet section will be present on one side in the height direction, while there will be no gusset sheet section on the other side in the height direction. As a result, when the contents are filled into the container, a difference in width will occur between the two sides in the height direction. Specifically, the width of the other side in the height direction, where the edges of the front sheet section and the back sheet section are directly sealed, will be wider than the width of the one side in the height direction, creating a visually cramped appearance. Furthermore, the increased width on the other side in the height direction will require more space when the containers are displayed side-by-side on a shelf in a store.
[0006] This disclosure has been made in view of the above-mentioned problems, and the purpose of this disclosure is to provide a pouch container that can suppress variations in width in the height direction, in which a gusset sheet portion is provided on one side in the height direction, and on the other side in the height direction, the end of the front sheet portion and the end of the back sheet portion are directly joined. [Means for solving the problem]
[0007] A pouch container according to this disclosure comprises a front sheet portion and a back sheet portion facing each other in the front-rear direction, and a gusset sheet portion connected to the front sheet portion and the back sheet portion on one side in the height direction perpendicular to the front-rear direction. Each of the front sheet portion and the back sheet portion has a first end located on one side in the height direction and a second end located on the other side in the height direction, and a first side end located on one side in the width direction perpendicular to the front-rear direction and the height direction and a second side end located on the other side in the width direction.
[0008] The pouch container further comprises: a periphery of the gusset sheet portion, a first joint that annularly connects the first end of the front sheet portion and the first end of the back sheet portion, a second joint that connects the second end of the front sheet portion and the second end of the back sheet portion, a first side end joint provided to connect one end of the first joint located on one side in the width direction with one end of the second joint located on the same side in the width direction, and connecting the first side end of the front sheet portion and the first side end of the back sheet portion, and a second side end joint provided to connect the other end of the first joint located on the other side in the width direction with the other end of the second joint located on the same side in the width direction, and connecting the second side end of the front sheet portion and the second side end of the back sheet portion.
[0009] In the pre-filling state, when the storage space formed between the front sheet portion and the back sheet portion is not filled with contents, and the gusset sheet portion is positioned so as to face forward, overlapping with the back sheet portion in the front-rear direction, when the gusset sheet portion and the front sheet portion are viewed from the front, the width of the gusset sheet portion in the width direction is greater than the width of the second joint portion in the width direction, and the first side end joint portion includes a first inclined portion that extends outward in the width direction from one end of the second joint portion toward one side in the height direction, and the second side end joint portion includes a second inclined portion that extends outward in the width direction from the other end of the second joint portion toward one side in the height direction. When the contents are filled into the above-mentioned storage space and the gusset sheet portion faces one side in the height direction, the first inclined portion and the second inclined portion extend along the height direction when the front sheet portion is viewed from the front side.
[0010] In the foregoing, the statement that the first and second inclined portions extend along the height direction includes not only cases where the first and second inclined portions are parallel to the height direction, but also cases where they are slightly inclined with respect to the height direction. For example, the first and second inclined portions may be inclined with respect to the height direction within a range of approximately plus or minus 5 degrees.

[0033] The embodiments of this disclosure will be described in detail below with reference to the drawings. In the embodiments described below, the same or common parts are denoted by the same reference numerals in the drawings, and their descriptions will not be repeated.
[0034] (Embodiment 1) Figures 1 and 2 are schematic side view and schematic perspective view, respectively, of a pouch container according to Embodiment 1, showing the container filled with contents. The pouch container 100 according to Embodiment 1 will be described with reference to Figures 1 and 2.
[0035] As shown in Figures 1 and 2, the pouch container 100 comprises a front sheet portion 10, a back sheet portion 20, a gusset sheet portion 30, a spout 50, a first joint portion 61, a second joint portion 62, a first side end joint portion 63, and a second side end joint portion 64.
[0036] The front sheet portion 10 and the rear sheet portion 20 face each other in the front-to-back direction (DR1 direction). The front sheet portion 10 constitutes the front side of the pouch container 100. The front sheet portion 10 has a first end portion 11, a second end portion 12, a first side end portion 13, and a second side end portion 14.
[0037] The first end 11 is located on one side in the height direction (DR2 direction) perpendicular to the front-rear direction. The second end 12 is located on the other side in the height direction. The first side end 13 is located on one side in the width direction (DR3 direction) perpendicular to both the front-rear and height directions. The second side end 14 is located on the other side in the width direction.
[0038] The back sheet portion 20 constitutes the back side of the pouch container 100. The back sheet portion 20 has a first end portion 21, a second end portion 22, a first side end portion 23, and a second side end portion 24.
[0039] The first end 21 is located on one side in the height direction. The second end 22 is located on the other side in the height direction. The first side end 23 is located on one side in the width direction. The second side end 24 is located on the other side in the width direction.
[0040] The gusset sheet portion 30 constitutes one side of the pouch container 100 in the height direction. The gusset sheet portion 30 has an outer main surface 30a facing outwards from the pouch container 100 (see Figure 3).
[0041] The gusset sheet section 30 is connected to the front sheet section 10 and the back sheet section 20 on one side in the height direction. Specifically, the peripheral edge of the gusset sheet section 30 is joined to the first end 11 of the front sheet section 10 and the first end 21 of the back sheet section 20 by an annular first joint 61. When the contents C described later are stored in the storage space, the first end 11 and the first end 21 are located at approximately the same height.
[0042] The first joint portion 61 has one end portion 61a (see Figure 3) located on one side in the width direction and the other end portion 61b (see Figure 3) located on the other side in the width direction.
[0043] The second end 12 of the front sheet portion 10 and the second end 22 of the back sheet portion 20 are directly joined by a second joint portion 62. The second joint portion 62 has a one-side end portion 62a located on one side in the width direction and a other-side end portion 62b located on the other side in the width direction.
[0044] The first side end 13 of the front sheet portion 10 and the first side end 23 of the rear sheet portion 20 are joined by a first side end joint 63. The first side end joint 63 is provided to connect one side end 61a of the first joint 61 and one side end 62a of the second joint 62.
[0045] The second side end 14 of the front sheet portion 10 and the second side end 24 of the rear sheet portion 20 are joined by a second side end joint 64. The second side end joint 64 is provided to connect the other side end 61b of the first joint 61 and the other side end 62b of the second joint 62.
[0046] A storage space for accommodating contents is formed between the front sheet portion 10 and the back sheet portion 20. Specifically, the space enclosed by the front sheet portion 10, the back sheet portion 20, and the gusset sheet portion 30 functions as the storage space. The contents C are stored in this storage space. The contents C may be, for example, liquid, granular, or powder.
[0047] The front sheet portion 10, the back sheet portion 20, and the gusset sheet portion 30 are made of, for example, a resin sheet. The resin sheet may be made of a single layer or multiple resin films.
[0048] The resin film that makes up the resin sheet is required to possess basic performance characteristics as a packaging material, such as impact resistance, abrasion resistance, and heat resistance. Furthermore, if the various joints mentioned above are formed by welding methods such as heat sealing, ultrasonic sealing, or high-frequency sealing, the resin film is also required to have heat-sealing properties.
[0049] As the resin sheet, a multilayer resin sheet having a base film and a sealant layer that provides heat sealability is preferred. When high gas barrier properties or light shielding properties are required, it is preferable to provide a barrier layer between the base film and the sealant layer. Alternatively, the base film itself may be provided with barrier properties. In this case, the barrier layer is used as the base film, resulting in a multilayer resin sheet having the barrier layer and the sealant layer.
[0050] The base film can be, for example, a film sheet made of polyester resin, polyolefin resin, or polyamide resin. The sealant layer can be, for example, a film sheet material primarily composed of polyolefin resin.
[0051] As the barrier layer, a thin metal film such as aluminum, a resin film such as vinylidene chloride (PVDC) or ethylene-vinyl alcohol copolymer (EVOH), or a film in which an inorganic oxide such as aluminum, aluminum oxide, or silica is laminated onto any synthetic resin film can be used.
[0052] Furthermore, the various joints may be formed by adhesives or the like, rather than by welding. Also, the resin sheet may be provided with a decorative layer. The decorative layer may be provided, for example, on the outer surface or the inner surface of the base film.
[0053] The spout 50 is provided on the gusset seat portion 30. The spout 50 includes a cover portion 51, a body portion 52, and a flange portion 53 (see Figure 3). The body portion 52 has a substantially cylindrical shape. The body portion 52 is provided so as to penetrate the gusset seat portion 30. The flange portion 53 is provided so as to extend radially outward from the base of the body portion 52. The flange portion 53 is provided, for example, in the shape of a flat ring. The flange portion 53 is joined to the inner main surface of the gusset seat portion 30. The flange portion 53 may also be joined to the outer main surface 30a of the gusset seat portion 30. The cover portion 51 closes the tip of the body portion 52 so as to be openable and closable.
[0054] Figure 3 is a front view of a pouch container according to Embodiment 1, showing the state before the contents are filled. Figure 4 is a schematic cross-sectional view along the line IV-IV shown in Figure 3.
[0055] Specifically, Figure 3 shows a front view of the pouch container 100 in its pre-filling state (first state), as shown in Figure 4. In this state, the contents are not filled into the storage space formed between the front sheet portion 10 and the back sheet portion 20, and the gusset sheet portion 30 is positioned overlapping with the back sheet portion 20 in the front-rear direction, with the outer main surface 30a of the gusset sheet portion 30 facing forward. In other words, Figure 3 shows a plan view of the pouch container 100 in the first state.
[0056] As shown in Figure 4, in the first state, a portion of the front sheet portion 10 is folded back to the other side in the height direction by a folding line P7 on one side in the height direction. As a result, in the first state, the first end 11 of the front sheet portion 10 is located on the other side in the height direction than the first end 21 of the back sheet portion 20. The folding line P7 is a virtual line that extends along the width direction. The folding line P7 is a virtual line that connects the intersections on both sides in the width direction of the front sheet portion 10, the back sheet portion 20, and the gusset sheet portion 30.
[0057] In the following explanation of Figure 3, we will describe the state of the pouch container 100 when viewed from the front side, specifically the gusset sheet portion 30 and the front sheet portion, in the first state described above.
[0058] As shown again in Figure 3, the width W1 of the gusset sheet portion 30 is greater than the width W2 of the second joint portion 62. The width W2 of the joint portion 62 is approximately the same as the width of the second end portions 12 and 22.
[0059] The first side end joint 63 described above has a first inclined portion 65 and a connecting portion 67. The first inclined portion 65 is connected to one side end 62a of the second joint 62. The first inclined portion 65 is inclined so that as it moves from the one side end 62a toward one side in the height direction, it moves toward the outside in the width direction (specifically, one side in the width direction).
[0060] Preferably, the angle θ1 on the side of the accommodation space formed by the first inclined portion 65 and the second joint portion 62 is greater than 90 degrees and 110 degrees or less. More preferably, the angle θ1 is greater than 90 degrees and 100 degrees or less.
[0061] The connecting portion 67 connects the end of the first inclined portion 65, which is located on one side in the height direction, to the one-side end 61a of the first joint portion 61. The connecting portion 67 may be slightly inclined outward in the width direction (to one side in the width direction) as it approaches one side in the height direction. In this case, the smaller of the angles formed between the imaginary line parallel to the height direction and the connecting portion 67 is smaller than the smaller of the angles formed between the imaginary line parallel to the height direction and the first inclined portion 65.
[0062] As described above, the inclination of the connection portion 67 enhances the fluidity of the contents C when it is discharged to the outside through the spout 50.
[0063] The connecting portion 67 may be omitted, and the end of the first inclined portion 65 located on one side in the height direction may be connected to the one-side end 61a of the first joint portion 61. Alternatively, the connecting portion 67 may be provided in a straight line parallel to the height direction without being inclined.
[0064] The second side end joint 64 has a second inclined portion 66 and a connecting portion 68. The second inclined portion 66 is connected to the other side end 62b of the second joint 62. The second inclined portion 66 is inclined so that as it moves from the other side end 62b toward one side in the height direction, it moves toward the outside in the width direction (specifically, toward the other side in the width direction).
[0065] Preferably, the angle θ2 on the side of the accommodation space formed by the second inclined portion 66 and the second joint portion 62 is greater than 90 degrees and 110 degrees or less. More preferably, the angle θ2 is greater than 90 degrees and 100 degrees or less.
[0066] The connecting portion 68 connects the end of the second inclined portion 66, located on one side in the height direction, to the other end 61b of the first joint portion 61. The connecting portion 68 may be slightly inclined outward in the width direction (to the other side in the width direction) as it approaches one side in the height direction. In this case, the smaller of the angles formed between the imaginary line parallel to the height direction and the connecting portion 68 is smaller than the smaller of the angles formed between the imaginary line parallel to the height direction and the second inclined portion 66.
[0067] As described above, the inclination of the connection portion 68 enhances the fluidity of the contents C when it is discharged to the outside via the spout 50.
[0068] The connecting portion 68 may be omitted, and the end of the second inclined portion 66 located on one side in the height direction may be connected to the other end 61b of the first joint portion 61. Furthermore, the connecting portion 67 may be provided in a straight line parallel to the height direction without being inclined.

[0071] The third side portion 33 is connected to one end of the first side portion 31, which is located on one side in the width direction. The third side portion 33 extends outward in the width direction (more specifically to one side in the width direction) and then toward the other side in the height direction.
[0072] The fourth side 34 is connected to one end of the second side 32, which is located on one side in the width direction. The fourth side 34 extends towards one side in the height direction as it moves outward in the width direction (more specifically to one side in the width direction).
[0073] The fifth side 35 is connected to the other end of the first side 31, which is located on the other side in the width direction. The fifth side extends outward in the width direction (more specifically to the other side in the width direction) and then toward the other side in the height direction.
[0074] The sixth side 36 is connected to the other end of the second side, which is located on the other side in the width direction. The sixth side is directed towards one side in the height direction as it moves outward in the width direction (more specifically to the other side in the width direction).
[0075] The seventh side portion 37 connects the end of the third side portion 33, which is located on one side in the width direction, and the end of the fourth side portion 34, which is also located on one side in the width direction. The seventh side portion 37 extends substantially parallel to the height direction.
[0076] The eighth side portion 38 connects the end of the fifth side portion 35, which is located on the other side in the width direction, and the end of the sixth side portion 36, which is also located on the other side in the width direction. The eighth side portion 38 faces the seventh side portion 37 in the width direction and extends substantially parallel to the height direction.
[0077] If the gusset sheet portion 30 is hexagonal, the seventh side portion 37 and the eighth side portion 38 may be omitted. In this case, the third side portion 33 and the fourth side portion 34 are directly connected, and the fifth side portion 35 and the sixth side portion 36 are directly connected.
[0078] A rounded first corner section C1 is provided at the connection point between the first side section 31 and the third side section 33. The first corner section C1 includes a first corner start point S1 located on one side in the width direction and a first corner end point E1 located on the other side in the width direction.

[0083] When a first imaginary line PL1 is drawn parallel to the height direction, extending from the first intersection point P1 toward one side in the height direction, this first imaginary line PL1 intersects with the first corner section C1 and the second corner section C2. In other words, the first imaginary line PL1 passes through the first corner section C1 and the second corner section C2.
[0084] If a second imaginary line PL2 is drawn parallel to the height direction, extending from the second intersection point P2 toward one side in the height direction, this second imaginary line PL2 intersects the third corner section C3 and the fourth corner section C4. In other words, the second imaginary line PL2 passes through the third corner section C3 and the fourth corner section C4.
[0085] At least a portion of one end 62a of the second joint 62 is located between a third imaginary line PL3, which connects the first corner starting point S1 and the second corner starting point S2 as described above and extends to the other side in the height direction, and a fourth imaginary line PL4, which connects the first corner ending point E1 and the second corner ending point E2 and extends to the other side in the height direction.

[0094] The first inner line 31B and the third inner line 33B intersect at the first inner intersection Q11. The first inner line 31B and the third inner line 33B are connected at the same first inner intersection Q11.

[0096] The second inner line 32B and the fourth inner line 34B intersect at the second inner intersection Q21. The second inner line 32B and the fourth inner line 34B are connected at the same second inner intersection Q21.

[0102] In this case, the first virtual line PL1 is located between the first virtual line PL7, which connects the first virtual intersection Q11 and the second virtual intersection Q21 and extends to the other side in the height direction, and the first virtual line PL8, which connects the first virtual intersection Q12 and the second virtual intersection Q22 and extends to the other side in the height direction, and the second virtual line PL2 is located between the second virtual line PL9, which connects the third virtual intersection Q31 and the fourth virtual intersection Q41 and extends to the other side in the height direction, and the second virtual line PL10, which connects the third virtual intersection Q32 and the fourth virtual intersection Q42 and extends to the other side in the height direction.
[0103] Furthermore, at least a portion of one end 62a of the second joint 62 is located between the first inner virtual line PL7 and the first outer virtual line PL8, and the other end 62b of the second joint 62 is located between the second inner virtual line PL9 and the second outer virtual line PL10.
[0104] In this embodiment, the example shown is that the first inner virtual line PL7 coincides with the fourth virtual line PL4 and the second inner virtual line PL9 coincides with the fifth virtual line PL5. However, the first inner virtual line PL7 and the second inner virtual line PL9 do not necessarily have to coincide with the fourth virtual line PL4 and the fifth virtual line PL5, respectively.
[0105] Figure 5 is a schematic front view of a pouch container according to Embodiment 1, showing the container filled with contents.
[0106] As described above, the pouch container 100 according to this embodiment 1 has a gusset sheet portion 30 on one side in the height direction, and on the other side in the height direction, the second end 12 of the front sheet portion 10 and the second end 22 of the back sheet portion 20 are directly joined by a second joint portion 62. In the first state, when viewed from the front, the width W1 of the gusset sheet portion 30 is greater than the width W2 of the second joint portion 62 (or the second ends 12, 22), and the first side end joint portion 63 includes a first inclined portion 65, and the second side end joint portion 64 includes a second inclined portion 66.
[0107] Therefore, as shown in Figure 5, in the post-filling state (second state) where the contents C are filled into the storage space and the gusset sheet portion 30 (more specifically the outer main surface 30a) faces one side in the height direction, the first inclined portion 65 and the second inclined portion 66 extend along the height direction. This makes it possible to suppress variations in width in the height direction when the contents C is filled. In addition, the appearance of the pouch container 100 can also be improved.
[0108] Furthermore, the statement that the first inclined portion 65 and the second inclined portion 66 extend along the height direction includes not only cases where the first inclined portion 65 and the second inclined portion 66 are parallel to the height direction, but also cases where the first inclined portion 65 and the second inclined portion 66 are inclined very slightly with respect to the height direction. For example, the first inclined portion and the second inclined portion may be inclined from the height direction within a range of approximately plus or minus 5 degrees.
[0109] Furthermore, when viewed from the front in the first state, by setting the angles θ1 and θ2 to be greater than 90 degrees and 110 degrees or less, the first inclined portion 65 and the second inclined portion 66 can be more easily moved along the height direction when the contents C are filled.
[0110] Furthermore, as described above, in the first state, when viewed from the front, the first virtual line PL1 is located between the first inner virtual line PL7 and the second outer virtual line PL8, and the second virtual line PL2 is located between the second inner virtual line PL9 and the second outer virtual line PL10. This makes it easier for the first inclined portion 65 and the second inclined portion 66 to move along the height direction when the contents C are filled.
[0111] Furthermore, in the first state, when viewed from the front, at least a portion of one end 62a of the second joint 62 is located between the first inner virtual line PL7 and the first outer virtual line PL8, and at least a portion of the other end 62b of the second joint 62 is located between the second inner virtual line PL9 and the second outer virtual line PL10. This makes it easier for the first inclined portion 65 and the second inclined portion 66 to move along the height direction when the contents C are filled.
[0112] In addition, as described above, when viewed from the front in the first state, the first imaginary line PL1 intersects with the first corner section C1 and the second corner section C2, and the second imaginary line PL2 intersects with the third corner section C3 and the fourth corner section C4, which makes it easier for the first inclined section 65 and the second inclined section 66 to move along the height direction when the contents C are filled.
[0113] Furthermore, as described above, when viewed from the front in the first state, at least a portion of one end 62a of the second joint 62 is located between the third virtual line PL3 and the fourth virtual line PL4, and at least a portion of the other end 62b of the second joint 62 is located between the fifth virtual line PL5 and the sixth virtual line PL6. This makes it easier for the first inclined portion 65 and the second inclined portion 66 to move along the height direction when the contents C are filled.
[0114] Furthermore, the pouch container 100 can maintain an upright position by placing the flat portion 51a of the lid portion 51 of the spout 50 in a predetermined position with the outer main surface 30a of the gusset sheet portion 30 facing downwards. As described above, when the first inclined portion 65 and the second inclined portion 66 are parallel to the height direction and the products are displayed side by side on a display shelf in a store, they can be efficiently arranged in the storage space.
[0115] (Embodiment 2) Figure 6 is a front view of the pouch container according to Embodiment 2, showing the state before the contents are filled. The pouch container 100A according to Embodiment 2 will be described with reference to Figure 6.
[0116] As shown in Figure 6, the pouch container 100A according to Embodiment 2 differs from the pouch container 100 according to Embodiment 1 in that the first corner portion C1 to the fourth corner portion C4 are not rounded but are angular. The other configurations are substantially the same.
[0117] In the pouch container 100A according to Embodiment 2, as described above, when viewed from the front in the first state, if a first imaginary line PL1 is drawn parallel to the height direction from the first intersection P1 toward one side in the height direction, the first imaginary line PL1 passes through the first corner C1 and the second corner C2, and if a second imaginary line PL2 is drawn parallel to the height direction from the second intersection P2 toward one side in the height direction, the second imaginary line PL2 passes through the third corner C3 and the fourth corner C4.
[0118] The first corner section C1 and the second corner section C2 are located between the first inner virtual line PL7 and the first outer virtual line PL8, while the third corner section C3 and the fourth corner section C4 are located between the second inner virtual line PL9 and the second outer virtual line PL10.
[0119] Furthermore, the first virtual line PL1 is located between the first inner virtual line PL7 and the first outer virtual line PL8, and the second virtual line PL2 is located between the second inner virtual line PL9 and the second outer virtual line PL10.
[0120] At least a portion of one end 62a of the second joint 62 is located between the first inner virtual line PL7 and the first outer virtual line PL8, and at least a portion of the other end 62b of the second joint 62 is located between the second inner virtual line PL9 and the second outer virtual line PL10.
[0121] Even when configured in this way, the pouch container 100A according to Embodiment 2 can obtain substantially the same effects as that of Embodiment 1.
[0122] (Embodiment 3) Figure 7 is a front view of the pouch container according to Embodiment 3, showing the state before the contents are filled. The pouch container 100B according to Embodiment 3 will be described with reference to Figure 7.
[0123] As shown in Figure 7, the pouch container 100B according to Embodiment 3 differs from the pouch container 100A according to Embodiment 2 in the position of the first corner portion C1 to the fourth corner portion C4. The other configurations are substantially the same.
[0124] The first corner section C1 and the second corner section C2 are located offset in the width direction from the first imaginary line PL1. Specifically, the first corner section C1 and the second corner section C2 are located outside (on one side in the width direction) of the first imaginary line PL1.
[0125] The third corner section C3 and the fourth corner section C4 are located offset in the width direction from the second virtual line PL2. Specifically, the third corner section C3 and the fourth corner section C4 are located outside the second virtual line PL2 in the width direction (on the other side in the width direction).
[0126] Furthermore, the first corner section C1 and the second corner section C2 may be located further inward in the width direction than the first imaginary line PL1. In this case, it is preferable that the third corner section C3 and the fourth corner section C4 are also located further inward in the width direction than the second imaginary line PL2.
[0127] In the pouch container 100B according to Embodiment 3, as described above, when viewed from the front in the first state, the first virtual line PL1 is located between the first inner virtual line PL7 and the first outer virtual line PL8, and the second virtual line PL2 is located between the second inner virtual line PL9 and the second outer virtual line PL10.
[0128] At least a portion of one end 62a of the second joint 62 is located between the first inner virtual line PL7 and the first outer virtual line PL8, and at least a portion of the other end 62b of the second joint 62 is located between the second inner virtual line PL9 and the second outer virtual line PL10.
[0129] Even when configured as described above, the pouch container 100B according to Embodiment 3 can obtain substantially the same effects as that of Embodiment 1.
[0130] In the embodiments 1 to 3 described above, the pouch containers 100, 100A, and 100B may be constructed by joining multiple sheets together, or by folding and joining a single sheet together.
