  Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 shows a pouch container 1 with a spout filled with a shampoo (hereinafter referred to as contents) for refilling a pump-type bottle container. This pouch container 1 with a spout is shown in FIG. As shown in (b), a flexible film having a thickness of about 100 to 200 μm obtained by laminating a biaxially stretched polyester film having a gas barrier sheet laminated on the outer surface of a synthetic resin film having thermal adhesive properties such as polyethylene and polypropylene. The pouch 10 is formed of a sheet and can be folded into a flat state, and a spout 20 formed of a heat-adhesive resin attached to the pouch 10.

  The pouch 10 is composed of a pair of front and back exterior sheets 12 and 13 and a gusset sheet 15 that is folded between the lower ends of the exterior sheets 12 and 13 as shown in FIG. The upper edge portion and both side edge portions of the exterior sheets 12 and 13 are heat-sealed to form the body portion 11, and the periphery of the gusset sheet 15 folded between the exterior sheets 12 and 13 is attached to the exterior sheet. The bottom gusset part 14 which closes the lower end opening part of the trunk | drum 11 by heat-sealing to the inner surface of 12 and 13 is formed.

The spout 20 is formed of a molded product of a heat-adhesive resin such as polyethylene or polypropylene, and is sandwiched between upper end edges of the exterior sheets 12 and 13 as shown in FIGS. 1 (b) and 2 (a) to (c). In this state, a flow passage 21a for contents is formed, which includes a flat boat-shaped mounting portion 22 that is heat-sealed to the exterior sheets 12 and 13 and a cylindrical mouth portion 23 that is connected to the mounting portion 22. The main body 21 and a heat-adhesive 20 to 100 μm thick polyethylene or polypropylene single-layer film that closes the flow path 21a formed in the main body 21 or a laminate of these heat-adhesive resins are laminated. And a channel closing body 25 formed of a layer film, and the mouth portion 23 of the main body portion 21 can be opened and closed by a screw cap 26 .

  A tapered surface 22b is formed at the opening end of the main body portion 21 on the side of the mounting portion 22 where the flow path 21a is opened. The tapered surface 22b is formed by chamfering the inner peripheral corner of the opening 22a over the entire circumference. A rib 24 is provided continuously to divide the opening 22a in the short direction of the mounting portion 22 (the thickness direction of the pouch 10).

  As shown in FIG. 2 (c), the channel closing body 25 is formed in a circular shape whose outer diameter is about 0.2 mm larger than the inner diameter of the opening 22a on the mounting portion 22 side, and its outer edge portion is entirely The rib 24 is heat-sealed in such a state as to project outside the opening 22a over the circumference. Note that the shaded display portion in FIG. 2C shows the heat seal portion of the flow path closing body 25.

  As described above, the spout-equipped pouch container 1 has an opening 22a at the outer edge portion so that the flow path closing body 25 formed of a thin film overlaps the opening end surface of the mounting portion 22 in the main body portion 21 of the spout 20. 3a, the outer portion of the rib 24 in the flow path closing body 25 is formed on the pouch 10 as shown in FIG. 3 (a). The pouch container 1 with a spout can be filled with the contents from the mouth 23 of the main body 21 because the flow path 21a formed in the main body 21 can be easily opened. Is possible.

Further, even if the spout pouch container 1 filled with the contents of the pouch 10 is mistakenly tilted with the screw cap 26 removed, the flow passage blocker 25 closes the attachment portion 22 side of the main body portion 21. Since the opening 22a is closed, the contents do not easily spill out from the mouth 23 of the spout 20.

  On the other hand, when the internal pressure of the pouch 10 is increased by pressing the pouch 10 filled with the contents, the outer portion of the rib 24 in the flow path closing body 25 is deformed as shown in FIG. Accordingly, a space is formed between the end of the outer portion of the rib 24 in the flow path closing body 25 and the flow path 21a, so that the pouch 10 filled with the contents is pressed. As a result, the contents can flow out of the spout 20.

  Further, when the pressing of the pouch 10 is released, the internal pressure of the pouch 10 is reduced, and accordingly, the flow path blocking body 25 that has entered the flow path 21a is restored to the original state, that is, the flow along the tapered surface 22b. Since the path closing body 25 is restored to the state in which the opening 22a is closed, the flow path 21a is not held in an open state, and the outflow of contents due to falling is prevented.

Further, in the above-described embodiment, the rib 24 is provided in the opening 22a on the mounting portion 22 side in the main body portion 21 of the spout 20, and the flow path blocker 25 is heat sealed to the rib 24. However, the present invention is not limited to this. For example, as shown in FIGS. 4 (a) to 4 (c), a body portion 21A in which no rib is provided in the opening 22a on the mounting portion 22 side is adopted, and the mounting portion 22 side in the main body portion 21A is employed. A pair of convex pieces 25a and 25a projecting in the longitudinal direction of the mounting portion 22 (width direction of the pouch 10) is provided on the circular flow path closing body 25A that is slightly larger than the opening 22a of the opening, and the outer edge of the flow path closing body 25A In such a state that the protrusions 25a and 25a protrude to the outside of the opening 22a, the projecting pieces 25a and 25a are heat sealed to the opening end face of the mounting portion 22, or a certain area is secured outside the opening 22a as shown in FIG. about If possible, in the state where the outer edge of the circular flow path closing body 25B that is slightly larger than the opening 22a protrudes outside the opening 22a, the longitudinal direction (pouch The same effect can be obtained even if both end portions in the width direction of 10 are point-sealed at the opening end face of the mounting portion 22 in the main body portion 21A . Contact name is shaded portion in FIG. 4 (c) and FIG. 5 shows a heat-sealed portion of the passage closing member 25A, 25B.

  When a certain area can be secured outside the opening 22a, as shown in FIG. 6, a circular flow path closing body 25C that is slightly larger than the opening 22a is provided over the entire periphery of the opening 22a. A pair of cuts 25b and 25b extending along the opening edge are formed in the non-sealed region outside the opening 22a by heat-sealing to the end face, thereby allowing the tongue pieces 25c and 25c to be separated from the opening end face of the mounting portion 22. The same effect can be obtained even when forming. In addition, the shaded display part in FIG. 6 has shown the heat seal part of the flow-path obstruction | occlusion body 25C.

  Moreover, like the flow path blockers 25D, 25E, and 25F shown in FIGS. 7 to 9, the flow path blockers 25, 25A, and 25B are arranged in the short direction of the mounting portion 22 (the thickness direction of the pouch 10). A pair of extending cuts 25d and 25d are formed, or similar cuts 25e and 25e are formed in the tongue piece portions 25c and 25c of the channel closing body 25C described above, like the channel closing body 25G shown in FIG. Is also possible.
