It can be done by transferring. If the top sheet 60 side of the top gusset sheet 64 rises, the top ends of the top gusset sheet 64 and the top sheet 60 that overlap each other are cut, and the height of the top ends is made lower than the back sheet 58 side.
  • the top gusset sheet 64 and the top sheet 60 can be cut, the top gusset sheet 64 is tilted again to return the pouch container 50 to a flat state. Then, both side portions of the pouch container 50 are heat sealed. At this time, in order to join the width direction both ends of the bottom seal portion 70b constituted by the top sheet 60 and the bottom gusset sheet 62 and the width direction both ends of the bottom seal portion 70b constituted by the back sheet 58 and the bottom gusset sheet 62. The point seal Ps is also applied.
  • both ends in the width direction of the top seal portion 70t configured by the top sheet 60 and the top gusset sheet 64 and both ends in the width direction of the top seal portion 70t configured by the back sheet 58 and the top gusset sheet 64 are joined.
  • a point seal Ps is also applied. If the side seal portion 70s and the point seal can be formed, a long sheet is cut for each width of one pouch container 50 (FIG. 32 (c)).
  • FIG. 32D shows the state of the pouch container 50 after cutting.
  • the plug 54 is inserted between the top gusset sheet 64 and the back sheet 58.
  • the first and second suction members are first held in a state where the top gusset sheet 64 is sucked and held by the first suction member (not shown) and the back sheet 58 is sucked and held by the second suction member (not shown).
  • the attaching part 74b of the cap 54 is inserted in this clearance gap.
  • the attachment portion 74b of the spigot 54 can be inserted between the back sheet 58 and the top gusset sheet 64, the upper end of the back sheet 58 and the top end of the top gusset sheet 64 are heat sealed with the attachment portion 74b being sandwiched.
  • the top sheet 60 is cut in the middle of manufacture to be lower than the back sheet 58. Therefore, the upper end of the back sheet 58 is exposed to the outside without being hidden by the top sheet 60. Therefore, the operation of separating the back sheet 58 and the top gusset sheet 64 described above, the operation of inserting the attachment portion 74b between the two sheets, and the operation of heat sealing the upper ends of both sheets can be easily performed.
  • the grip portion 68 is configured by a sheet similar to the sheet configuring the pouch container 50.
  • the step of forming the opening 71 in the top sheet 60 (FIG. 31B) and the step of joining the top sheet 60 and the interior sheet 66 (FIG. 31C).
  • the grip portion 68 can be easily configured.
  • the pouch container 50 including the grip portion 68 can be manufactured without significantly changing the conventional manufacturing process.
  • the attaching step of the plug 54 can be performed in the same procedure as before.
  • the cutting process (FIG. 32 (b)) of the surface sheet 60 described above may be omitted.
  • the point seal Ps may be formed not before but before the plug 54 is attached. That is, when the point seal Ps is not formed in the process of FIG. 32C, the folded gusset sheet 64 can be lifted on one side as shown in FIG. Therefore, after the side seal portion 70s is formed and the long sheet is cut to a predetermined width, the top sheet 60 side of the top gusset sheet 64 is raised using the guide rail 90, and the back sheet 58 side is set to the outside.
  • the plug 54 may be attached in this state after being exposed. And after attaching the plug 54, you may form the point seal
  • the up-down direction length of the surface sheet 60 can be made the same as the up-down direction length of the back surface sheet 58, the capacity
  • the long holes in the up and down direction arranged in the width direction are illustrated as the openings 71 as described above.
  • interposed into two long holes among the surface sheets 60 functions like a handle which a user holds.
  • the shape, the number, and the size of the opening 71 are not particularly limited as long as fingers can be inserted. Therefore, the opening 71 may not be an opening such as a long hole, but may be a cut formed by breaking the topsheet 60 into a line.
  • the number of openings 71 may be plural or singular. When there are a plurality of openings 71, as shown in FIG.
  • a portion between the opening 71 and the opening 71 in the top sheet 60 functions as a handle that is held by the user.
  • the opening 71 is elongated in the vertical direction, but the opening 71 may be elongated in the width direction as long as it has a length that can be inserted by a finger. Further, for example, four openings for receiving one finger may be formed side by side (see FIG. 24 of the first embodiment), and when gripping the pouch container 50, a finger may be inserted into each opening.
  • FIG. 33 is a perspective view of a pouch container 50x in which a tongue piece 78 is provided in the opening 71 (a state in which the tongue piece 78 is folded inward), and FIG. 34 is a sectional view taken along the line GG in FIG.
  • the tongue piece 78 is partially connected to the topsheet 60x at the edge of the opening 71, and the remaining portion is separated from the topsheet 60x.
  • the tongue piece 78 is turned (folded) outward or inward as shown in FIG.
  • a curved surface 78 a is formed at the edge of the opening 71 by the tongue piece 78. Due to the presence of the curved surface 78a, the biting of the edge of the opening 71 into the finger is alleviated and the gripping property is improved.
  • the openings and cuts that make up the openings 71 do not have to be formed in advance, and perforations and half-cut lines for forming the openings and cuts may be formed only on the top sheet 60. In this case, when the user needs the grip portion 68 such as when pouring the contents, the top sheet 60 may be broken along the perforation line or the half cut line to form the opening 71.
  • the interior sheet 66 desirably has the same width as that of the top sheet 60 for the convenience of manufacture. However, the interior sheet 66 does not necessarily have the same width, and the width of the interior sheet 66 may be smaller than the width of the top sheet 60. Further, the end face of the interior sheet 66 can be isolated from the internal space of the pouch container 50 as in the case of the first embodiment (see FIGS. 10 to 12).
  • the configuration described so far is an example, and other configurations are possible as long as the pouch container 50 has the bottom gusset sheet 62 and the top gusset sheet 64 and the grip portion 68 on the side opposite to the attachment surface of the plug 54. It may be changed as appropriate. For example, the size (aspect ratio) of the pouch container 50 may be changed as appropriate.
