[0015] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the embodiments described below, the same or common portions are denoted by the same reference numerals in the drawings, and descriptions thereof will not be repeated.

[0016] (Embodiment 1) Figure 1 is a schematic perspective view of the pouch container according to Embodiment 1. Figure 2 is a schematic cross-sectional view taken along line II-II shown in Figure 1. The pouch container 100 according to Embodiment 1 will be described with reference to Figure 1 and Figure 2.

[0017] As shown in Figure 1 and Figure 2, the pouch container 100 according to Embodiment 1 includes a front wall portion 11, a rear wall portion 12, an upper wall portion 13, a bottom wall portion 14, and a spout 60.

[0018] The front wall portion 11 and the rear wall portion 12 face each other in the front-rear direction (direction DR1). The upper wall portion 13 is disposed between the front wall portion 11 and the rear wall portion 12, and constitutes the upper wall of the pouch container 100. The bottom wall portion 14 is disposed between the front wall portion 11 and the rear wall portion 12, and constitutes the bottom of the pouch container 100. The upper wall portion 13 and the bottom wall portion 14 face each other in the up-down direction (direction DR2).

[0019] The upper wall portion 13 is provided with the spout 60. The spout 60 has a lid portion 61, a body portion 62, and a flange portion 63 (see Figure 3). The body portion 62 has a substantially cylindrical shape and is provided so as to penetrate through the upper wall portion 13. The flange portion 63 is provided so as to extend from the base of the body portion 62 to the radially outer side of the body portion 62. The flange portion 63 is formed, for example, in a flat ring shape. The flange portion 53 is joined to the inner surface of the upper wall portion 13. Note that the flange portion 53 may be joined to the outer surface of the upper wall portion 13. The lid portion 61 openably and closably closes the tip end of the body portion 62.

[0020] A storage space is defined by a front wall portion 11, a rear wall portion 12, an upper wall portion 13, and a bottom wall portion 14, and the storage space is filled with a content C. As the content C, for example, liquid, granular, or powdery materials can be appropriately employed.

[0021] The rear wall portion 12 has an extension portion 121 that extends upward beyond the upper end 11a of the front wall portion 11 and a spout 60 when viewed from the front. The extension portion 121 is curved such that a central portion 121c in the left-right direction is located rearward of both ends 121a and 121b in the left-right direction. Note that the both ends 121a, 121b and the central portion 121c may be arranged linearly along the left-right direction.

[0022] The extension portion 121 is provided with a penetration portion 15 and a cutting guide portion 16. The penetration portion 15 is provided so as to penetrate the extension portion 121 in the front-rear direction. The penetration portion 15 is provided on the upper side of the extension portion 121, and is provided substantially at the center in the left-right direction (DR3 direction). The penetration portion 15 is provided above the cutting guide portion 16. As the shape of the penetration portion 15, a circular shape, an elliptical shape, an oval shape, a polygonal shape, a block shape in which the central portion in the left-right direction protrudes upward, and the like can be appropriately employed. Further, the penetration portion 15 may be formed by a U-shaped notch or the like.

[0023] The cutting guide portion 16 indicates a cutting position of the extension portion 121, and is a portion for guiding cutting of the extension portion 121. The cutting guide portion 16 is provided below the penetration portion 15. The cutting guide portion 16 is provided so as to extend along the left-right direction. When viewed from the front, the cutting guide portion 16 is located below the upper end 60a of the spout 60. Note that the upper end 60a of the spout 60 is constituted by the upper surface of a lid portion 61.

[0024] The front wall portion 11 is composed of a front sheet portion 20. The bottom wall portion 14 is composed of a bottom gusset sheet portion 50. The top wall portion 13 and the rear wall portion 12 are composed of a top gusset sheet portion 30 and a rear sheet portion 40. More specifically, the top wall portion 13 is composed of a part of the top gusset sheet portion 30, and the rear wall portion 12 is composed of the remaining part of the top gusset sheet portion 30 and the rear sheet portion 40.

[0025] The rear seat portion 40 includes an opposing portion 41 and a protruding portion 42. The opposing portion 41 faces the front seat portion 20 in the front-rear direction. The protruding portion 42 protrudes upward from the opposing portion 41.

[0026] The top gusset sheet portion 30 is positioned above the front sheet portion 20 and the rear sheet portion 40. The top gusset sheet portion 30 includes an upper wall component portion 31 and an extended portion 32. The upper wall component portion 31 is a part that constitutes the upper wall portion 13. The upper wall component portion 31 has a front peripheral edge portion 311 located on the front side and a rear peripheral edge portion 312 located on the rear side. The peripheral edge portion of the upper wall component portion 31 is formed by the front peripheral edge portion 311 and the rear peripheral edge portion 312.

[0027] The front peripheral edge 311 is joined to the upper end 20a of the front sheet portion 20. The rear peripheral edge 312 is joined to the upper end 41a of the opposing portion 41.

[0028] The extended portion 32 extends from the rear of the upper wall component 31 so as to face the protruding portion 42. The extended portion 32 is joined to the protruding portion 42 to form the extended portion 121.

[0029] The bottom gusset sheet portion 50 is positioned on the lower side, between the front sheet portion 20 and the rear sheet portion 40. The bottom gusset sheet portion 50 may be omitted, in which case the lower end of the front sheet portion 20 and the lower end of the rear sheet portion 40 are joined together.

[0030] The front sheet portion 20, the top gusset sheet portion 30, the rear sheet portion 40, and the bottom gusset sheet portion 50 are made of, for example, a resin sheet. The resin sheet may be made of a single layer or multiple resin films.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] Furthermore, the various joints 71-76 (see Figure 3), described later, may be formed by adhesive or the like instead of welding. Also, the resin sheet may be provided with a design layer. The design layer may be provided, for example, on the outer surface of the base film or on the inner surface. In particular, if the extension portion 121 is provided with a design layer, the extension portion 121 can be made to function as a display portion that displays information about the contents C. For example, by placing the pouch container 100 in the store so that the extension portion 121 is visible from the front, the display portion printed on the extension portion 121 can easily attract the attention of customers.

[0036] Figure 3 is a plan view of the pouch container according to Embodiment 1, showing the state before the contents are filled. More specifically, Figure 3 illustrates the state of the pouch container 100 before filling, in which the contents are not filled into the storage space, and the top gusset sheet portion 30 faces forward, with the top gusset sheet portion 30 overlapping the rear sheet portion 40 in the front-to-back direction. In this state, the upper side of the front sheet portion 20 is folded back downward.

[0037] The joining method of the pouch container 100 and the details of the cutting guide section 16 will be described with reference to Figures 2 and 3.

[0038] As shown in Figures 2 and 3, the pouch container 100 includes a front joint 71, a rear joint 72, a left joint 73, a right joint 74, a lower joint 75, and an extension joint 76.

[0039] The front joint 71 is the portion where the front peripheral edge 311 of the upper wall component 31 and the upper end portion 20a of the front sheet portion 20 are joined. The rear joint 72 is the portion where the rear peripheral edge 312 of the upper wall component 31 and the upper end portion 41a of the opposing portion 41 are joined. The front joint 71 and the rear joint 72 form an annular joint.

[0040] The left-side joint 73 is the area where the left end 11c of the front seat portion 20 and the left end 12c of the rear seat portion 40 are joined. The right-side joint 74 is the area where the right end 11d of the front seat portion 20 and the right end 12d of the rear seat portion 40 are joined.

[0041] The lower joint portion 75 is the area where the peripheral edge of the bottom gusset sheet portion 50 is joined to the lower peripheral edge of the front sheet portion 20 and the lower peripheral edge of the rear sheet portion 40.

[0042] In this way, the pouch container 100 is formed into a bag shape by providing the front joint portion 71, the rear joint portion 72, the left joint portion 73, the right joint portion 74, and the lower joint portion 75.

[0043] The extension joint 76 is the portion where the extended portion 32 of the top gusset sheet portion 30 and the protruding portion 42 of the rear sheet portion 40 are joined. More specifically, the extension joint 76 is the portion formed by joining the extended portion 32 and the protruding portion 42 together. The extension portion 121 is formed by joining the extended portion 32 and the protruding portion 42.

[0044] As described above, the extension portion 121 is provided with a cutting guide portion 16. In this embodiment, the cutting guide portion 16 is made up of perforations. The perforations are made up of a linear pattern of alternating cut portions and uncut portions of the extension portion 121. The cut portions may be provided so as to penetrate the extension portion 121, or they may be formed by half-cuts without penetrating the extension portion 121.

[0045] The cutting guide section 16 has a first end 16a and a second end 16b on both sides in the left-right direction. The first end 16a is the left end and is formed by the left end of the leftmost cutting section in the perforation. The second end 16b is the right end and is formed by the right end of the rightmost cutting section in the perforation.

[0046] The first end 16a and the second end 16b are located inward from both ends of the extension 121 in the left-right direction. More specifically, the first end 16a is located to the right of the left end of the extension 121, and a non-penetrating portion is provided between the left end of the extension 121 and the first end 16a, through which the extension 121 does not pass. The second end 16b is located to the left of the right end of the extension 121, and a non-penetrating portion is provided between the right end of the extension 121 and the second end 16b, through which the extension 121 does not pass.

[0047] As described above, in the pouch container 100 according to Embodiment 1, since the extension portion 121 is provided with a through portion 15, the pouch container 100 can be suspended by passing the through portion 15 through a hook portion or the like provided on a display shelf.

[0048] Furthermore, by providing a cutting guide section 16 below the penetration section 15, when removing the contents C from the spout 60, the extension section 121 can be cut along the cutting guide section 16, thereby preventing interference between the remaining extension section 121 in the pouch container 100 and the contents C. Additionally, interference between the remaining extension section 121 in the pouch container 100 and surrounding objects can be prevented. This improves the workability when removing the contents.

[0049] Furthermore, by providing the cutting guide section 16 below the upper end of the spout 60, it is possible to more reliably prevent interference between the remaining portion of the extension 121 in the pouch container 100 and the contents C when the extension 121 is cut along the cutting guide section 16.

[0050] Furthermore, as described above, in the left-right direction, the ends of the perforations are located inward from the ends of the extension portion 121, thereby preventing the perforations from being partially cut when an external force is applied to both ends of the extension portion 121 in unintended circumstances.

[0051] In addition, visibility can be improved by the curvature of the extension portion 121 such that the central portion 121c in the left-right direction is located behind both ends 121a and 121b in the left-right direction. The curvature of the extension portion 121 prevents the extension portion 121 from bending unintentionally when, for example, the pouch container 100 is suspended, and a good suspension state is maintained. In other words, the curved shape of the extension portion 121 improves its resistance to bending.

[0052] The degree of curvature of the extension portion 121 can be adjusted by setting the length of the extension portion 121 in the left-right direction relative to the left-right length of the pouch container 100. When viewed from above, for example, if the upper wall portion 13 is approximately hexagonal in shape, the degree of curvature increases as the left-right length of the extension portion 121 increases, and the degree of curvature decreases as the left-right length of the extension portion 121 decreases.

[0053] Furthermore, the central portion 121c and both ends 121a and 121b may be arranged in a substantially straight line. In this case, the design can be enhanced by having the extended portion 121 stand substantially parallel to each other in the vertical direction.

[0054] Furthermore, the extension portion 121 is formed by joining the extended portion 32 and the protruding portion 42, which increases the rigidity of the extension portion 121 and makes it easy to maintain an upright position.

[0055] (Embodiment 2) Figure 4 is a plan view showing the pouch container according to Embodiment 2 before the contents are filled. The pouch container 100A according to Embodiment 2 will be described with reference to Figure 4.

[0056] As shown in Figure 4, the pouch container 100A according to Embodiment 2 differs from the pouch container 100 according to Embodiment 1 in that notches 122 and 123 are provided at both ends of the extension portion 121 in the left-right direction. The other configurations are substantially the same.

[0057] The notches 122 and 123 are provided such that their vertical length decreases as they move inward. The notches 122 and 123 have, for example, a roughly semicircular shape, and a cutting guide section 16 is provided between the notches 122 and 123.

[0058] By providing approximately semicircular notches 122 and 123, even if an external force acts on both ends of the extension 121 in the left-right direction in an unintended situation, the external force can be distributed in an arc shape. This makes it possible to suppress the cutting of the area near the notches 122 and 123 in an unintended situation.

[0059] Furthermore, the shape of the notches 122 and 123 is not limited to a semicircular shape as described above; it may also be a semi-oval shape, or any shape that facilitates cutting of the cutting guide portion 16 can be appropriately adopted. In addition, although the above example illustrates the case where the notches 122 and 123 are provided at both ends of the extension portion 121 in the left-right direction, the notches may be provided at either end of the extension portion 121 in the left-right direction.

[0060] Even when configured as described above, the pouch container 100A according to Embodiment 2 provides substantially the same effects as that of Embodiment 1.

[0061] (Embodiment 3) Figure 5 is a plan view showing the pouch container according to Embodiment 3 before the contents are filled. The pouch container 100B according to Embodiment 3 will be described with reference to Figure 5.

[0062] As shown in Figure 5, the pouch container 100B according to Embodiment 3 differs from the pouch container 100 according to Embodiment 1 in the shape of the cutting guide section 16B. The other configurations are almost the same.

[0063] The cutting guide section 16B is provided with V-shaped cutting sections arranged at intervals in the left-right direction. More specifically, the cutting guide section 16B is provided with a pair of cutting sections 161 and 162 arranged at predetermined intervals in the left-right direction, with the distance between them increasing as they move toward one side in the vertical direction.

[0064] Even when configured as described above, the pouch container 100B according to Embodiment 3 provides substantially the same effects as that of Embodiment 1.

[0065] (Embodiment 4) Figure 6 is a plan view showing the pouch container according to Embodiment 4 before the contents are filled. The pouch container 100C according to Embodiment 4 will be described with reference to Figure 6.

[0066] As shown in Figure 6, the pouch container 100C according to Embodiment 4 differs from the pouch container 100 according to Embodiment 1 in the configuration of the cutting guide section 16C. The other configurations are almost the same.

[0067] The cutting guide section 16C is composed of cutting indicator lines. These cutting indicator lines may be straight lines or dashed lines. In this case, the extension 121 is cut along the cutting guide section 16C using a cutting tool such as scissors.

[0068] Even when configured as described above, the pouch container 100C according to Embodiment 4 provides substantially the same effects as that of Embodiment 1.

[0069] (Other variations) In the embodiments 1 to 3 described above, the extension portion 121 is formed by joining the extension portion 32 and the projection portion 42, but the invention is not limited to this, and the extension portion 121 may be formed by the projection portion 42 alone. In this case, the top gusset sheet portion 30 does not have an extension portion 32, and the top gusset sheet portion 30 is formed by the upper wall component portion 31 alone. Alternatively, the extension portion 121 may be formed by the extension portion 32 of the upper wall portion 13 alone. In this case, the rear sheet portion 40 does not have a projection portion 42, and is formed by the opposing portion 41 alone.

[0070] Furthermore, while embodiments 1 to 3 described above illustrate the case in which the extension portion 121 has a substantially rectangular shape with rounded corners at both ends in the left-right direction of the upper end, the extension portion 121 is not limited to this, and can adopt any appropriate shape when viewed from the front, such as a trapezoidal shape, a rectangular shape, a polygonal shape, or a shape with an arc-shaped outer edge.

[0071] Furthermore, the pouch containers 100 to 100C according to the above-described embodiments 1 to 3 may be constructed by joining multiple sheets, or by folding and joining a single sheet.

[0072] The embodiments disclosed herein are illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims, and all modifications are within the meaning and scope equivalent to the claims. [Explanation of symbols]
