A valve body for closing the inlet is attached to the inlet of the contents in the pipe so as to be openable to the outside of the outlet pipe, and the valve is attached to the outlet pipe. It is an object of the present invention to provide a pouch container with a spout, characterized in that a folding means for folding the distal end side to which the body is attached is formed.

  In order to solve the above-mentioned problem, the invention according to claim 4 is a pouch container with a spout in which a spout having a spout that can be opened and closed is attached to the pouch, and the spout protrudes into the pouch. A lead-out pipe having a content inflow port, and in order to widen the content inflow port, the lead-out pipe is formed with a folding means for folding the tip side including the inflow port. A pouch container with a spout characterized by the above is provided.

  The invention according to claim 5 is a pouch container with a spout in which a spout having a spout that can be opened and closed is attached to the pouch, the spout having a lead-out pipe protruding into the pouch, and the lead-out. A valve body in which an inlet for contents smaller than the inner diameter of the outlet pipe is formed in an openable and closable manner at the distal end of the pipe in a state that it can be opened to the outside of the outlet pipe. The lead-out tube is provided with a pouch container with a spout, wherein the lead-out pipe is formed with a folding means for folding the tip end side to which the valve body is attached. The "inlet" here does not need to be open at all times. For example, a cut such as a cross is formed in the valve body, and the internal pressure of the pouch is increased by pressing the pouch filled with the contents. By increasing, the cut portion is elastically deformed to form an inflow port.

  As described above, the pouch container with a spout according to the first aspect of the present invention is such that the spout outlet is closed by the outlet pipe whose pipe is closed. Does not flow out of the spout, and the leading end side including the closed portion of the lead-out pipe is broken, so that an inlet for the contents is formed in the lead-out pipe, and the contents can be poured out.

  Therefore, the spout with a spout is opened so that the contents can be poured into the bottle container etc. by opening the spout outlet of the spout along the mouth of the bottle container etc. to which the contents are to be transferred. If the tip side including the closed part of the outlet pipe is folded from the outside of the pouch while holding the container, the contents are poured from the spout outlet into the mouth of the bottle container etc. When transferring to a bottle container or the like, the contents can be reliably refilled in a stable state without spilling the contents.

  In particular, in the pouch container with a spout according to the second aspect of the present invention, since the outlet pipe with the closed passage is formed of a material having a gas barrier property, oxygen does not enter the pouch through the spout, and the spout It is possible to obtain an effect that the contents staying in the vicinity of are not easily deteriorated.

  In addition, the pouch container with a spout according to the third aspect of the present invention can open and close the valve body that closes the inflow port at the inflow port of the contents in the outflow tube so that it can be opened to the outside of the outflow tube. Since it is attached, when the contents are injected from the spout of the spout, the valve body is opened by the injection pressure, and it is possible to fill the contents in a short time.

  In addition, by handling the pouch container with a spout in the same manner as the pouch container with a spout according to the first aspect of the present invention, the contents can be refilled reliably without spilling the contents. The effect similar to that of the pouch container with a spout of the invention according to claim 1 can be obtained.

  Further, in the pouch container with a spout according to a fourth aspect of the present invention, since the spout outlet pipe has a content inlet, the contents can flow out of the spout when the spout is opened. However, since the inlet formed in the outlet pipe in advance is formed with a smaller diameter than the new inlet formed by breaking the tip side including the inlet in the outlet pipe. Even if the attached pouch container is tilted, a large amount of content does not flow out of the spout outlet, and a large amount of content is poured out by breaking the tip side including the inlet in the outlet pipe. It will be in a state that can be.

  Therefore, in order to transfer the contents to a bottle container, etc., when the spout with spout is tilted so that the spout spout is opened and the spout is along the mouth of the bottle container, etc. From the outside of the pouch, the spilled contents are not easily spilled outside the mouth of the bottle container, etc., and the contents spilled from the spout spout can be reliably poured into the bottle container. When the leading end side of the outlet pipe including the inlet is broken, a large amount of content is poured from the spout outlet into the mouth of the bottle container, etc., so that the content refilling operation is stable. It can be done efficiently.

  In addition, in the state where the leading end side of the outlet pipe having a small-diameter inlet is not broken off, as described above, a large amount of content does not flow out from the spout outlet, so the content can be removed from the bottle container, etc. This pouch container with a spout can be used as it is without being refilled.

  According to a fifth aspect of the present invention, there is provided a spout container with a spout according to the present invention, wherein the content inlet of the outlet pipe is smaller than the inner diameter of the outlet pipe in a state where the outlet can be opened outside the outlet pipe. Since the valve body formed of is attached so as to be openable and closable, when the contents are injected from the spout outlet, the valve body is opened by the injection pressure, and the contents can be filled in a short time An effect is obtained.

  In addition, when the pouch container with a spout is handled in the same manner as the pouch container with a spout of the invention according to claim 4, when the contents are refilled into another container, the refilling operation is efficiently performed in a stable state. It is possible to obtain the same effect as the pouch container with a spout of the invention according to claim 4, wherein the pouch container with a spout can be used as it is without refilling the contents into a bottle container or the like. it can.

  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 thickness of 100 laminated with a biaxially stretched polyamide film or a biaxially stretched polyester film in which a gas barrier sheet or the like is laminated on the outer surface of a synthetic resin film having thermal adhesive properties such as polyethylene or polypropylene. The pouch 10 is formed of a flexible sheet of about 200 μm and can be folded in 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, it is heat-sealed to the exterior sheets 12 and 13, and is attached to the flat boat-shaped mounting portion 22 with a through hole formed in the center, and protrudes to the outside of the pouch 10 connected to the mounting portion 22. A main body portion 21 including a cylindrical mouth portion 23 having a spout at the tip and a lead-out pipe 24 projecting inside the pouch 10 and a screw cap 26 for opening and closing the spout of the mouth portion 23 in the main body portion 21 are provided. The cylindrical mouth portion 23 and the outlet tube 24 communicate with each other through a through hole formed in the mounting portion 22.

  The lead-out tube 24 of the main body 21 has a gas barrier property that blocks the passage of oxygen, and its distal end is closed, and its proximal end side is for folding the closed distal end. A circumferential groove 24a is formed. Therefore, even if the screw cap 26 is removed and the spout of the mouth portion 23 is opened, the closed tip portion is broken off and the content inflow port E is inserted into the outlet tube 24 as shown in FIG. The contents filled in the pouch 10 will not flow out from the spout of the mouth 23 unless the pouch 10 is formed.

  As described above, the spout-equipped pouch container 1 is configured such that the contents can be poured into the bottle container along the mouth of the bottle container in which the contents are to be transferred through the spout of the mouth part 23. When the closed end portion of the outlet tube 24 is broken from the outside of the pouch 10 while being held in the state, the contents are poured from the mouth portion 23 of the spout 20 into the mouth portion 23 of the bottle container. When the contents are transferred to the bottle container, the contents can be refilled in a stable state without spilling the contents.

  In addition, since the outlet tube 24 whose tip is closed has a gas barrier property, this spout pouch container 1 has a gas barrier property, so that oxygen does not enter the pouch 10 through the spout 20 and stays near the spout 20. It is possible to obtain an effect that the contents are not easily deteriorated. In order to impart gas barrier properties to the lead-out pipe 24, a gas barrier resin may be laminated, or an inorganic film having gas barrier properties may be formed on the surface.

  Further, this spout 20 has a certain length on the tip side from the circumferential groove 24a in order to make it easy to break the outlet tube 24 at the circumferential groove 24a, but is not limited to this. For example, as shown in FIGS. 3A and 3B, the outlet tube 24 whose tip is closed may be shortened, and a pressing piece 24b having a certain length may be continuously provided at the tip.

  Further, the spout 20 has the leading end of the outlet tube 24 closed, but the spout 20 is not limited to this. As shown in FIGS. You may make it form the obstruction | occlusion wall 24c which obstruct | occludes the pipe line in an intermediate part. However, it goes without saying that the blocking wall 24c must be provided on the tip side of the circumferential groove 24a in the outlet tube 24.

  Further, as shown in FIGS. 5A to 5C, when the pressing piece 24 b is continuously provided on the distal end surface of the closed outlet pipe 24, the pressing piece 24 b is surrounded not on the outer peripheral surface of the outlet pipe 24. As shown in FIG. 4D, the content is formed on the distal end surface of the outlet tube 24 by forming the circumferential groove 24a on the closed distal end surface and pushing the pressing piece 24b to break the inner side of the circumferential groove 24a. You may make it form the inflow port E of a thing.

  Fig.6 (a)-(c) has shown spout 20A currently used for the pouch container with a spout which is other embodiment. Since this spout 20A also has substantially the same configuration as the spout 20 described above, common constituent elements will be denoted by the same reference numerals, description thereof will be omitted, and different constituent elements will be described.

  In the spout 20 of the above-described embodiment, the outlet tube 24 has the same inner diameter over its entire length and the tip is closed, but the tip of the outlet tube 24A of the spout 20A gradually becomes smaller in diameter. Since the content inlet e is opened at the tip, when the screw cap 26 is removed and the spout of the mouth 23 is opened, the content can flow out from the spout. Since the inlet e of the pipe 24A is formed to be smaller in diameter than the inner diameter of the outlet end of the outlet pipe 24A, a large amount of contents do not flow out of the spout of the mouth portion 23. FIG. ), The front end side having the inflow port e is broken at the circumferential groove 24a, so that a large inflow port E is formed in the outlet pipe 24A, and a large amount of contents can be poured out. .

  Therefore, when the pouch container with a spout is tilted so that the spout of the mouth part 23 is aligned with the mouth part of the bottle container in order to transfer the contents to the bottle container, the content that flows out from the mouth part 23 of the spout 20A. In the state where the contents are less likely to spill outside the mouth of the bottle container and the contents that have flowed out from the mouth 23 of the spout 20A can be reliably poured into the bottle container, the inflow e from the outside of the pouch When the leading end side of the outlet pipe 24A having a fold is broken, a large amount of content is poured from the mouth part 23 of the spout 20A into the mouth part of the bottle container at that time, so that the refilling operation of the contents is stable. It can be done efficiently.

  Further, in the state where the leading end side of the outlet pipe 24A having the small-diameter inlet port e is not broken, as described above, a large amount of content does not flow out from the mouth portion 23 of the spout 20A. Since things are poured out moderately, it is possible to use this pouch container with a spout as it is without refilling the contents into a bottle container.

  In addition, the pouch container with a spout is configured to change the amount of the spout 20A discharged from the mouth portion 23 by breaking the outlet tube 24A protruding into the pouch, so that the pouch container protrudes outside the pouch. The mouth of the spout becomes longer and the appearance of the entire container is not impaired as in the case of changing the amount of pouring by breaking off the existing mouth.

  The spout 20A has a gradually decreasing diameter on the tip side, and the content inlet e is opened at the tip. However, the present invention is not limited to this, for example, as shown in FIG. As described above, a small hole 24d serving as an inflow port is formed on the peripheral surface of the outlet pipe 24 where the tip of the spout 20 is blocked as described above, or as shown in FIG. A small hole 24d serving as an inlet is formed, or as shown in FIGS. 8 (a) to 8 (c), an inflow port is formed on the distal end surface of the outlet pipe 24 where the spout pressing piece 24b shown in FIG. A small hole 24d may be formed. Further, when a small hole 24d serving as an inflow port is formed on the distal end surface of the outlet pipe 24 with which the pressing piece 24b is continuously provided, the pressing piece 24b and the small hole 24d are surrounded similarly to the spout shown in FIG. As described above, a large-diameter inlet is formed on the distal end surface of the outlet pipe 24 by forming a peripheral groove on the distal end surface of the outlet pipe 24 and pressing the pressing piece 24b to break the inner side of the peripheral groove. Good.

  Further, as in each of the above-described embodiments, when a spout in which the conduit of the outlet pipe 24 is blocked or a spout in which the small holes 24d and the small-diameter inlets e are formed in the outlet pipes 24 and 24A, the contents from the spout are used. There is a problem that it is impossible to fill the contents at all or that it takes too much time to fill the contents, so that the contents cannot be substantially filled from the spout.

  Therefore, as in the spout 20B shown in FIGS. 9 (a) to 9 (c), a lead-out tube 24B having the same inner diameter over the entire length and having a content inlet at the tip is adopted, and A rib 24e that divides the inlet is provided, and an elastically deformable valve body 25 that closes the inlet is attached to the rib 24e so that the valve body 25 can be opened to the outside of the outlet pipe 24B. As in the spout 20C shown in a) to (c), a lead-out pipe 24C having the same inner diameter over the entire length and having an inflow port for contents is adopted at the tip, and the tip of the lead-out pipe 24C projects outward in the radial direction. When the rib 24f is formed and the elastically deformable valve body 25 that closes the inflow port is attached to the rib 24f in such a state that it can be opened to the outside of the outlet pipe 24C, FIG. ), (B) and FIG. As shown by a chain line, when injected contents from the spout 20B, 20C of the mouth portion 23, the by injection pressure opens the valve body 25, it is possible to fill the contents in a short time.

  In addition, since the contents do not flow out from the mouths 23 and 23 of the spouts 20B and 20C unless the distal ends of the outlet pipes 24B and 24C to which the valve bodies 25 and 25 are attached are broken off, the spout is attached. By handling in the same manner as the pouch container 1, the pouch container 1 with a spout can reliably perform the refilling operation of the contents in a stable state without spilling the contents when the contents are transferred to the bottle container. The same effect can be obtained.

  In addition, the refilling of the contents can be performed efficiently in a stable state, and the contents can be used as they are without being refilled into a bottle container etc. Further, the contents can be filled from a spout. 11 (a) and 11 (b), small holes 25a and 25a serving as inflow ports are formed in the valve bodies 25 and 25 of the spouts 20B and 20C, as shown in FIGS. As shown in c), when a notch 25b such as a cross is formed in the valve body 25 of the spout 20C and the internal pressure of the pouch is increased by pressing the pouch filled with the contents, the notch 25b portion is elastically deformed. The inlet port may be formed in the valve body 25. In addition, the cut formed in the valve body 25 is not limited to a cross, and it is also possible to adopt a Y shape, an H shape, an S shape, an I shape, or the like.

  In the above-described embodiment, the pouch container with a spout in which a spout is attached to a bottom gusset type pouch has been described. However, the present invention is not limited to this, and the spout is attached to various pouches other than the bottom gusset type. Needless to say, the present invention can be applied to a pouch container with a spout.
