  • the top sheet 11 and back sheet 12 are directly joined via the cutout portion 18.
  • Each side seal portion 22 is formed by directly joining the widthwise edges of the top sheet 11 and the back sheet 12. One side seal portion 22 is formed at one end of both widthwise ends. The other side seal portion 22 is formed at the other end of both widthwise ends.
  • Each side seal portion 22, like the top seal portion 20 and the bottom seal portion 21, is an edge seal portion for sealing the storage chamber 17.
  • Each side seal portion 22 is formed by extending in the vertical direction.
  • each side seal portion 22 has, in the up-down direction, an upper portion 221, a lower portion 222, and a central portion 223 between the upper portion 221 and the lower portion 222.
  • the upper portion 221 and the lower portion 222 are formed as narrow portions, while the central portion 223 is formed as a wide portion.
  • Each side seal portion 22 has an inner end 224 on the side of the storage chamber 17 and an outer end 225 opposite the inner end 224.
  • the inner end 224 extends in the vertical direction from the lower portion 222 to the upper portion 221. More specifically, the inner end 224 is curved toward the storage chamber 17 so that the left-right seal width of the central portion 223 is longer than the left-right seal widths of the upper portion 221 and the lower portion 222.
  • the outer end 225 extends in the vertical direction from the lower portion 222 to the upper portion 221. In this example, the outer end 225 is straight.
  • the pouch 1 has a plug 30 in the center of the top sheet 14 for storing and removing the object 40.
  • the plug 30 includes a spout 31 and a cap 32.
  • the spout 31 is fixed to the top sheet 14.
  • the cap 32 screws into a threaded portion formed on the outer periphery of the spout 31. Note that FIG. 1 shows the spout 31 with the cap 32 removed.
  • the spout 31 has a cylindrical portion 31a and a flange portion 31b.
  • the cylindrical portion 31a protrudes outward from the top sheet 14.
  • the flange portion 31b is integrally formed at the end of the cylindrical portion 31a.
  • the flange portion 31b is circular.
  • the flange portion 31b is attached to the inner surface of the top sheet 14 (i.e., the surface facing the storage chamber 17) by, for example, heat sealing.
  • the notch 24 formed in each side seal portion 22 will be described. As shown in FIG. 1, the notch 24 is formed in the central portion 243 of the side seal portion 22. More specifically, the notch 24 is formed in the vertical direction in the central portion 243. More specifically, the notch 24 has an upper portion 241, a lower portion 242, and a central portion 243.
  • Each notch 24 curves along the inner end 224 of the side seal portion 22. More specifically, the central portion 243 curves along the inner end 224. The central portion 243 is convex toward the storage chamber 17 and extends in the vertical direction.
  • the upper portion 241 and the lower portion 242 are arc-shaped.
  • the central angle of the arc between the upper portion 241 and the lower portion 242 is an obtuse angle.
  • the upper portion 241 and the lower portion 242 are located closer to the outer end portion 225 than the central portion 243.
  • the tip of the upper portion 241 and the central portion 243 are spaced apart by a predetermined distance.
  • the tip of the upper portion 241 and the central portion 243 are spaced apart by a predetermined distance.
  • the reason why the upper portion 241 and the lower portion 242 have the above-mentioned shapes is to prevent the side seal portion 22 from tearing from the tip of the notch 24 due to the weight of the pouch 1 when the user grasps the pouch 1, as described below.
  • each notch 24 provided in each side seal portion 22 is used by the user of the pouch 1 to grip the pouch 1. Specifically, each notch 24 is used by the user to grip the pouch 1 with one hand. For this reason, each notch 24 has a vertical length that allows the user to insert a finger into the side seal portion 22. In this example, the two notches 24 have the same length.
  • FIG. 3 shows a state in which a user is holding pouch 1 with one hand.
  • the user is lifting pouch 1 with thumb 91 of left hand 90 inserted into one of the notches 24 of the two side seal portions 22, and with middle finger 93 and ring finger 94 inserted into the other notch 24 of the two side seal portions 22.
  • notches 24 may be configured so that index finger 92 and little finger 95 can be inserted in addition to middle finger 93 and ring finger 94.
  • the pouch 1 has a notch 24 formed in each of both side seal portions 22, allowing the user to easily grip the pouch 1.
  • the user can grip the pouch 1 closer to the storage chamber 17 than when gripping the outer end portion 225 (see FIG. 1) of the side seal portion 22. This allows the user to hold the thumb 91 and other finger (index finger 92) with a smaller gap.
  • the gap between the thumb 91 and other fingers can be narrower than when the central portion 243 is straight.
  • the notch 24 is formed in the central portion 223, which is the wide portion, so that the reduction in strength of the side seal portion 22 caused by the notch 24 can be reduced compared to a configuration in which the notch 24 is formed in a narrow portion.
  • each notch 24 may be a perforation that tears when a finger is inserted.
  • a certain area including the position where the notch 24 is formed may be an unsealed area (an area where the top sheet 11 and the back sheet 12 are not joined). That is, each notch 24 may be formed in the unsealed area. Since the sheets are not joined to each other in the unsealed area, it is softer than the sealed area where the sheets are joined to each other. Therefore, by forming each notch 24 in the unsealed area, the user's fingers feel softer when holding the pouch 1 with one hand compared to a configuration in which each notch 24 is formed in a sealed area.
  • the pouch 1 includes a pair of body sheets (top sheet 11 and back sheet 12) joined on both sides in the width direction, a bottom sheet 13 joined to the lower part of each body sheet, a top sheet 14 joined to the upper part of each body sheet, and a spout 31 attached to the top sheet.
  • a side seal portion 22, which is a joint, is formed on each of the two side edges of the pair of body sheets.
  • Each side seal portion 22 extends along the up-down direction, which is the opposing direction of the top sheet 14 and the bottom sheet 13.
  • Each side seal portion 22 has a slit 24 formed therein through which a finger can be inserted.
  • each side seal portion 22 is curved toward the storage chamber 17 so that the left-right seal width of the central portion 223 is longer than the left-right seal widths of the upper portion 221 and the lower portion 222.
  • the central portion 223 is formed as a wide portion.
  • the notch 24 is formed in the central portion 223.
  • the notch 24 is formed in the wide central portion 223, and as described above, the reduction in strength of the side seal portion 22 caused by the notch 24 can be reduced compared to a configuration in which the notch 24 is formed in a narrow portion.
  • the notch 24 is curved along the inner end 224 of each side seal portion 22. Therefore, as described above, the gap between the thumb 91 and the other fingers can be narrower than when the notch 24 (more specifically, the central portion 243) is straight.
  • FIG. 4 is a front view of a pouch 1A in a folded state before containing an object to be contained.
  • pouch 1A has a through hole 25 formed in each side seal portion 22.
  • Pouch 1A differs from pouch 1 of embodiment 1 in that two through holes 25 are formed instead of two notches 24. Therefore, the following description will focus on the through holes 25.
  • the through hole 25 is formed in the central portion 223 of the side seal portion 22. Specifically, the through hole 25 is formed in the vertical direction in the central portion 223. More specifically, the through hole 25 has an upper end opening 251, a lower end opening 252, and a central opening 253. The central opening 253 is continuous with the upper end opening 251 and the lower end opening 252.
  • the central opening 253 has an inner opening 253a on the inner end 224 side (storage chamber 17 side) of the side seal portion 22, and an outer opening 253b on the outer end 225 side.
  • the inner opening 253a curves along the inner end 224 of the side seal portion 22. More specifically, the inner opening 253a curves along the inner end 224.
  • the inner opening 253a is convex toward the storage chamber 17 side and extends in the vertical direction.
  • the outer opening 253b extends linearly in the vertical direction. The distance between the outer opening 253b and the inner opening 253a is greatest near the center of the outer opening 253b.
  • the upper end opening 251 and the lower end opening 252 are arc-shaped. In this example, the central angle of the arc between the upper end opening 251 and the lower end opening 252 is approximately 180 degrees.
  • the upper end opening 251 is upwardly convex.
  • the lower end opening 252 is downwardly convex. The reason why the upper end opening 251 and the lower end opening 252 have the above-mentioned shapes is to prevent the side seal portion 22 from tearing starting from the tip of the through hole 25 due to the weight of the pouch 1A when a user inserts a finger into the through hole 25 and grasps the pouch 1A, as described below.
  • Each through hole 25 provided in each side seal portion 22 is used by the user to grip the pouch 1A, similar to the notches 24 in embodiment 1. Specifically, each through hole 25 is used by the user to grip the pouch 1A with one hand. For this reason, each through hole 25 has a vertical length and width (horizontal length) that allows the user's fingers to be inserted into the side seal portion 22. In this example, the two through holes 25 have the same length.
  • the pouch 1A has a through hole 25 formed in each of both side seal portions 22, allowing the user to easily grasp the pouch 1A.
  • the user can grasp the pouch 1A closer to the storage chamber 17 than when grasping the outer end portion 225 of the side seal portion 22. This allows the user to open the pouch 1A with a smaller gap between the thumb 91 and the other finger (index finger 92).
  • the inner opening 253a of the central opening 253 is curved along the inner end 224, so the gap between the thumb 91 and the other finger (index finger 92) can be narrower than if the inner opening 253a were straight.
  • the pouch 1A includes a pair of body sheets (top sheet 11 and back sheet 12) joined on both sides in the width direction, a bottom sheet 13 joined to the lower part of each body sheet, a top sheet 14 joined to the upper part of each body sheet, and a spout 31 attached to the top sheet.
  • a side seal portion 22, which is a joint portion, is formed on each of the two side edges of the pair of body sheets.
  • Each side seal portion 22 extends along the up-down direction, which is the opposing direction of the top sheet 14 and the bottom sheet 13.
  • Each side seal portion 22 is formed with a through hole 25 through which a finger can be inserted.
  • each side seal portion 22 is curved toward the storage chamber 17 so that the left-right seal width of the central portion 223 is longer than the left-right seal widths of the upper portion 221 and the lower portion 222.
  • the central portion 223 is formed as a wide portion.
  • the through hole 25 is formed in the central portion 223.
  • the through hole 25 is curved along the inner end 224 of each side seal portion 22. Therefore, the gap between the thumb 91 and the other fingers can be narrower than when the through hole 25 (more specifically, the inner opening 253a) is straight.
