  By the way, since the pouch container 50 described above is used in a state of being hung and suspended in the suspension hole 52 formed in the center portion in the width direction of the pouch body 51, the synthetic resin sheet forming the pouch body is used. The pouch body can be hermetically sealed by firmly heat-sealing the peripheral part over the entire circumference, and the pouch body can be opened by breaking the pouch body below the heat-sealed upper edge part. Instead, this is dealt with by partitioning the inside of the pouch body 51 with a partition wall portion 54 that is easily opened by pressing from the outside.

  Therefore, when the pouch container 50 is transported or stored, if the chamber partitioned by the partition wall portion 54 in the pouch body 51 is accidentally pressed from the outside, the partition wall portion 54 is opened, and the fastener member Since only 53 cannot secure a completely sealed state, there is a problem that the liquid food or the like as the contents is altered or leaked.

  Accordingly, an object of the present invention is to provide a pouch container that can ensure a sufficient sealing performance even when suspended near the center in the width direction.

  In order to solve the above-mentioned problems, the invention according to claim 1 is directed to heat sealing between a pouch body filled with a liquid food or an enteral nutrient and a pair of front and back flexible sheets forming the pouch body. A pouch container that is attached to a lower edge of the pouch and includes a spout member that can be opened and closed. The pouch body includes a pair of upper and lower flexible sheets that are heat-sealed to each other. Suspension holes are formed in the edge portion, and the pouch body rises in a state where any one of the flexible sheets is partially overlapped on the upper portion, and the upper edge and both side edges are closed. A pair of fastener members meshing with the inner surfaces of the pair of front and back flexible sheets on the lower side of the base end portion of the branch portion in the pouch body. Is mounted, said The Kibe, there is provided a pouch container, characterized in that is adapted to open by breaking at its proximal end near.

  As described above, the pouch container of the invention according to claim 1 is designed to be opened by breaking the branch portion formed in the upper portion of the pouch body in the vicinity of the base end portion thereof. The inside of the pouch body can be sealed by firmly heat-sealing the peripheral portion of the flexible sheet, and the upper edge portion of the pouch in which the hanging hole is formed is not cut off by opening the pouch. It can be hung near the center in the width direction.

  Therefore, the conventional pouch body is defined by a partition portion that is easily opened by pressing from the outside without heat-sealing the upper edge in which the suspension hole is formed in order to suspend it near the center in the width direction. Like a pouch container, there is no risk that the contents such as liquid food will be altered or leaked during transportation and storage.

  Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 shows a pouch container 1 filled with a liquid food or the like. As shown in the figure, the pouch container 1 includes a pouch main body 10 filled with liquid food and the like, and a pouch attached to the pouch main body 10 for pouring the liquid food filled in the pouch main body 10 and the like. And an outlet member 20.

  The pouch body 10 has a base material layer made of a biaxially stretched polyester film, a biaxially stretched polyamide film, or the like, and a sealant layer made of low density polyethylene, high density polyethylene, linear low density polyethylene, polypropylene, metallocene polyethylene, or the like. A top sheet 11 and a back sheet 12 formed by laminated flexible sheets (a gas barrier layer in which an inorganic material such as an aluminum foil or silicon oxide is deposited may be laminated on a base layer if necessary) The top sheet 11 and the back sheet 12 are formed in a flat bag shape by heat-sealing the peripheral edges of each other in a state where the inner surfaces are in contact with each other, and are heat-sealed with each other. A spout member 20 is attached to the lower edge of the. In addition, the shaded display part in the figure shows the heat seal part of the pouch body 10.

  The top sheet 11 forming the front side of the pouch main body 10 is divided into an upper surface sheet 11a with the lower part folded upward and a lower surface sheet 11b with the upper part superimposed on the folded part of the upper surface sheet 11a. 11B of branch parts are formed by the heat-sealing of the upper edge and both-sides edge in the overlapping part of both.

  The upper edge of the branch part 11A is located below the upper edge of the pouch body 10, and the upper edge of the pouch body 10 in which the upper surface sheet 11a and the back sheet 12 are heat-sealed with each other, A suspension hole 10a is formed above the upper edge of the branching portion 11A.

  In addition, in the base end portion of the branch portion 11A, cuts 10b are formed at both heat-sealed side edges, and hot water is injected by breaking the branch portion 11A triggered by the cuts 10b. The inlet portion M is formed.

  In addition, on the lower side of the branch portion 11A in the pouch main body 10, the inner surface of the lower surface sheet 11b and the back sheet 12 is thermally bonded to the sealant layer of the surface sheet 11 (lower surface sheet 11b) and the back sheet 12. A pair of interlocking belt-like fastener members 13 formed of a plastic material having heat resistance are thermally welded so that the injection port portion M formed by breaking the branch portion 11A can be opened and closed. It has become.

  In addition, a strip-shaped partition wall portion 14 is formed below the fastener member 13 in the pouch body 10 so as to vertically divide a space filled with the liquid food or the like, and the liquid food filled in the pouch body 10 or the like. Is not in contact with the fastener member 13.

  The partition wall portion 14 has a lower sealing strength than the heat seal portions at the periphery of the upper surface sheet 11a, the lower surface sheet 11b, and the back surface sheet 12, and the lower side of the partition wall portion 14 filled with liquid food or the like. When the internal pressure is increased by pressing the seal, a seal breakage occurs in the partition wall portion 14 having a low sealing strength, the sealed topsheet 11 (lower surfacesheet 11b) and backsheet 12 are separated from each other, and the pouch body 10 The upper part and the lower part communicate with each other.

  The spout member 20 includes a main body 21 having a spout and a screw cap 22 that opens and closes the spout of the main body 21. The screw cap 22 is removed and an adapter is screwed into the main body 21. The tube can be connected to this adapter.
