SUMMARY OF THE INVENTION An object of the present invention is to provide a method for manufacturing a packaging container that allows a pouch with a spout to be smoothly accommodated in a standing pouch.

In order to achieve the above object, the first invention has a spouted pouch and a self-supporting standing pouch,
The spouted pouch has a pouch body and a spout provided at one end of the pouch body,
The standing pouch has an opening at the top and a foldable bottom sheet at the bottom,
A method for manufacturing a packaging container in which a pouch with a spout is housed in a standing pouch,
Fold the pouch body of the spouted pouch in two, turn the spout downward,
inserting the spouted pouch into the standing pouch through the opening of the standing pouch with the spout protruding below the lower end of the folded pouch body;
By pushing the folded bottom sheet portion downward from the inside of the standing pouch with the mouth plug of the pouch with a spout, the bottom sheet portion is unfolded from the folded state and the standing pouch stands on its own.

According to this, when the spouted pouch is stored in the standing pouch with the entrance of the standing pouch opened, the spout of the spouted pouch protrudes below the lower end of the folded pouch body. First, the mouth plug is first inserted into the loading and unloading opening, and at this time, the loading and unloading opening is expanded by the mouth plug, and immediately after that, the pouch main body is subsequently inserted into the loading and unloading opening while maintaining this state. . As a result, the pouch body is less likely to get caught on the upper end of the standing pouch, and the spouted pouch can be smoothly inserted into the standing pouch.

In addition, when the spouted pouch is inserted into the standing pouch from the insertion/removal opening, the mouth plug of the spouted pouch pushes the bottom sheet portion of the standing pouch downward, causing the bottom sheet portion to expand from the folded state and the standing pouch to be dislodged. become self-reliant. At this time, even if the thickness of the pouch body of the spouted pouch in which the items are stored is thinner than the diameter of the spout, the spout can sufficiently spread the bottom sheet portion of the standing pouch. The independence of the standing pouch can be ensured.

The manufacturing method of the packaging container according to the second aspect of the present invention is to weld and close the loading/unloading opening of the standing pouch.

According to this, the outside and the inside of the standing pouch are reliably cut off.

In the manufacturing method of the packaging container in the present third invention, the pouch body of the spouted pouch has an inwardly recessed constricted portion at the folded portion.

According to this, the pouch body can be easily folded at the folding portion. In addition, when the spouted pouch is taken out from the standing pouch and held by the hand, the frictional resistance between the hand and the spouted pouch is increased by grasping the constricted part, making the spouted pouch less slippery and gripping. improve sexuality.

In the method for manufacturing a packaging container according to the fourth aspect of the present invention, the standing pouch has at least one of a light shielding property, a water vapor barrier property that makes it difficult for water vapor to pass through, and an oxygen barrier property that makes it difficult for oxygen to pass through. There is.

According to this, since the standing pouch can block light, water vapor, or oxygen, it is possible to prevent deterioration of the quality of the items stored in the pouch with the spout. In addition, there is no need to impart light-shielding properties, water vapor barrier properties, or oxygen barrier properties to the spout-equipped pouch, and the spout-equipped pouch can be easily produced.

As described above, according to the present invention, the pouch body is less likely to get caught on the upper end of the standing pouch, and the spouted pouch can be smoothly inserted into the standing pouch.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, reference numeral 1 denotes a packaging container having a double structure in which a spouted pouch 2 is accommodated in a self-supporting standing pouch 3. As shown in FIG. A powder 5 such as protein (an example of the content, see FIG. 3) is contained in the spout-equipped pouch 2 .

As shown in FIGS. 2 and 3 , the spouted pouch 2 has a pouch body 6 and a spout 7 provided at the upper end of the pouch body 6 . The pouch body 6 is formed by heat-sealing a pair of front and rear sheets 9, 10 and a bottom sheet 11 to form a square bag. Also, the spout 7 has a communicating hole communicating with the inside of the pouch body 6 and a rotatable detachable cap 14 for opening and closing the communicating hole.

As shown in FIGS. 1 and 4, the pouch body 6 is stored in the standing pouch 3 with the spout 7 facing downward and folded in two. At this time, the spout 7 protrudes downward from the lower end of the folded pouch body 6 .

The pouch body 6 has a constricted portion 16 that is inwardly recessed in a U or V shape at a bending portion 15 . That is, the constricted portions 16 are formed on both sides of the pouch body 6 and enter from the outside to the inside of the pouch body 6 .

As shown in FIGS. 4 and 5, the standing pouch 3 is formed by heat-sealing a pair of front and rear sheet portions 21 and 22 and a bottom sheet portion 23 into a rectangular bag shape, and has an opening 25 at the upper end. are doing.

The bottom sheet portion 23 is provided between the lower portions of the sheet portions 21 and 22 and can be folded into an inverted V shape.

As shown in FIGS. 1 and 7, the bottom sheet portion 23 of the spouted pouch 2, in which the plug 7 is folded, is pushed downward from within the standing pouch 3, thereby unfolding the bottom sheet portion 23 from the folded state. The space between the bottoms of the front and rear sheet portions 21, 22 of the standing pouch 3 is enlarged, and the standing pouch 3 stands on its own.

In the manufacturing process, the insertion/removal opening 25 of the standing pouch 3 is closed by heat welding as shown by the phantom lines in FIGS. Thereby, the inside of the standing pouch 3 is sealed.

The front and rear sheet portions 21 and 22 and the bottom sheet portion 23 of the standing pouch 3 are made of a light-shielding film and a gas-barrier film, respectively. A film made of, for example, aluminum is used as the light-shielding film. In addition, the gas barrier film has a water vapor barrier property that makes it difficult for water vapor to permeate and an oxygen barrier property that makes it difficult for oxygen to permeate. Materials such as coalescence, polyamide-based resin, polychlorotrifluoroethylene-based resin, polyacrylonitrile-based resin are used.

A method for manufacturing the packaging container 1 will be described below.

As shown in FIG. 4, the pouch body 6 of the spouted pouch 2 is folded in two and the spout 7 faces downward. At this time, the pouch body 6 can be easily folded because the constricted portion 16 is formed at the folding portion 15 of the pouch body 6 .

Then, as shown in FIG. 6, the spout-equipped pouch 2 is inserted into the standing pouch 3 through the opening 25 of the standing pouch 3 with the spout 7 protruding below the lower end of the folded pouch body 6 . insert.

At this time, the spout 7 is first inserted into the loading/unloading port 25. At this time, the loading/unloading port 25 is expanded by the spigot 7, and the pouch main body 6 immediately follows while maintaining this state. is inserted into the loading/unloading port 25. As a result, the pouch body 6 is less likely to get caught on the upper end of the standing pouch 3, and the spouted pouch 2 can be smoothly inserted into the standing pouch 3.例文帳に追加

When the spouted pouch 2 is inserted into the standing pouch 3 through the loading/unloading port 25 as described above, the spout 7 of the spouted pouch 2 faces downward with the bottom sheet portion 23 of the standing pouch 3 as shown in FIG. Since the bottom sheet part 23 is pushed, the bottom sheet part 23 is expanded from the folded state, the space between the bottom parts of the front and rear sheet parts 21 and 22 of the standing pouch 3 is expanded, and the standing pouch 3 can stand on its own.

At this time, even if the thickness T (see FIG. 6) of the pouch body 6 of the spouted pouch 2 containing the powder 5 is thinner than the diameter D (see FIG. 3) of the cap 14 of the spout 7, , the bottom sheet portion 23 can be sufficiently expanded by the cap 14, so that the standing pouch 3 can be secured on its own.

1 and 7, the opening 25 of the standing pouch 3 is closed and sealed by heat welding. As a result, the outside and inside of the standing pouch 3 are reliably cut off, and the packaging container 1 containing the spouted pouch 2 inside the standing pouch 3 is manufactured.

Since the standing pouch 3 has a light shielding property, a water vapor barrier property and an oxygen barrier property, it is possible to prevent deterioration of the quality of the powder 5 stored in the spout-equipped pouch 2 . In addition, the spouted pouch 2 can be easily manufactured without the necessity of imparting a light shielding property, a water vapor barrier property, or an oxygen barrier property to the spouted pouch 2 .

A method of using the packaging container 1 will be described below.

The upper end of the standing pouch 3 is broken to open the loading/unloading opening 25, and the pouch 2 with the spout inside the standing pouch 3 is taken out of the standing pouch 3 through the loading/unloading opening 25.例文帳に追加

After that, as shown in FIG. 3, the pouch main body 6 of the spouted pouch 2 is straightened from the folded state so that the spout 7 faces upward, and the cap 14 is turned and removed to open the spout 7 . Next, water is supplied into the pouch body 6 from the communication hole of the spout 7, and then the cap 14 is attached to close the spout 7. The powder 5 inside and water are stirred and mixed.

At this time, by gripping the constricted portion 16 of the spouted pouch 2 with the hand, the frictional resistance between the hand and the spouted pouch 2 is increased, so that the spouted pouch 2 becomes less slippery and the grip is improved. In the pouch body 6, the powder 5 and water collide with the constricted portion 16 as indicated by the dotted arrow A in FIG. 3 and flow complicatedly in multiple directions. be done.

After that, the cap 14 is turned and removed to open the spout 7, and the mixture of the powder 5 and water in the pouch body 6 is poured out from the spout 7 and drunk.

According to this, in order to supply water into the pouch body 6, the pouch body 6 must have an internal volume corresponding to the amount of water supplied, and the height of the pouch body 6 increases accordingly. 4, the height of the packaging container 1 can be reduced by folding the pouch body 6 in two.

In the above-described embodiment, the spouted pouch 2 is stored in the standing pouch 3, but the spouted pouch 2 and an instruction manual may be stored.
