This foaming packaging bag contains liquids or fluids such as detergents or cosmetics as contents, so that even ordinary detergents or cosmetics that do not have high foaming power are foamed like conventional dispensers. It can be used.

  As a film used when manufacturing the foaming packaging bag of the present invention, a laminated film or a single layer film which has flexibility and appropriate strength and can be bag-formed by heat sealing can be suitably used.

The heat-sealable thermoplastic synthetic resin used for the innermost layer of the laminated film or the single-layer film includes low-density polyethylene, linear low-density ethylene-α-olefin copolymer, linear ultra-low-density polyethylene α-olefin copolymer, ethylene-vinyl acetate copolymer, polypropylene, ionomer, ethylene-acrylic acid copolymer, ethylene-methacrylic acid copolymer, ethylene-methyl methacrylate copolymer, ethylene-based polymerized by metatheron catalyst Although a polymer etc. can be employ | adopted, it is not restricted to these.
Further, as the intermediate layer and the outer layer in the laminated film, various materials having a melting point higher than that of the thermoplastic synthetic resin used for the innermost layer can be used.

  As the sponge used in the present invention, a soft sponge excellent in elasticity and liquid (or fluid) absorption, having a thickness of about 10 to 40 mm, and further having a thickness of about 20 to 30 mm is preferably used. can do.

Hereinafter, Example 1 of the foaming packaging bag 10 that embodies the present invention as a detergent container will be described.
As shown in FIGS. 1 to 3, the foaming packaging bag 10 includes a storage portion 4 formed by heat-sealing the folded film 3 at the bottoms of the front and rear trunk films 1 and 2.
The storage portion 4 has a thickness that is easy to grip, particularly so that the center portion (body portion 4a) is pinched by hand.
In addition, an upper portion of the foaming packaging bag 10 is arranged between the front and rear trunk films 1 and 2 so that the base end portion 5b of the pouring tool 5 constituting the spout provided with the cap 5a is connected to the storage portion 4. It is fused and fixed.
Therefore, this lathering packaging bag 10 is suitable for repeated use by opening and closing the cap 5a, and lathering out the detergent from the pouring tool 5 to the outside little by little. It is compact and convenient to carry, and can be suitably used as an alternative to conventional dispensers.

  As the trunk films 1 and 2 and the folding film 3 in this example, a laminated film of biaxially stretched nylon film (15 μ) / polyurethane adhesive / linear low density polyethylene (100 μ) is used.

Since the storage part 4 is formed so as to swell so that the width of the bottom part of the foaming packaging bag 10 is wide and constitutes the contents storage part 4b, the foaming packaging bag 10 can be self-supporting.
A sponge 6 and contents 7 are stored in the body 4a and the contents storage 4b of the storage 4.
Since the contents 7 are particularly stored in the contents storage portion 4b, the bottom of the packaging bag 10 becomes heavy and can be made more stable and independent.
Further, the lower part 4c around the base part 5b of the pouring tool 5 is formed so as to protrude outward from the body part 4a, and only the body part 4a of the storage part 4 is thinly recessed. Even if it exists, it is a shape which is easy to grasp and is easy to squeeze the trunk | drum 4a with a hand.

Moreover, the said extraction | pouring tool 5 is being fixed to the foaming packaging bag 10 so that the front end side may face diagonally upward of the foaming packaging bag 10, and it is easy to use the content 7 by extracting.
Furthermore, the cap 5a was removed even when the packaging bag 10 was overturned by making the width (periphery dimension) of the sponge close to the inner surface of the body 4a of the storage part 4 that is not bulged. It is possible to prevent the contents 7 from flowing out from the state of the dispensing tool 5.

As the sponge 6 accommodated inside the foaming packaging bag 10, a polyurethane foam can be suitably used, and a net (mesh cloth) made of acrylic, nylon, polyester, polypropylene, or the like. When the material covered with is used, foaming is good and the restorability of the storage part 4 can be improved.
When there is no net, the sponge is too sticky to the inner surface of the packaging bag, and the storage part deformed by gripping the storage part is difficult to return from the deformed state.

Next, an example of a method for producing the foaming packaging bag 10 of the present invention will be described.
In order to manufacture the lathering packaging bag 10 of the present invention, the folding film 3 is folded and inserted between the long and thin trunk films 1 and 2 stacked vertically.

And the film of 1, 2 and 3 of a bottom part and a side part is melt | fused (heat-sealed), and the upper part of the trunk | drum films 1 and 2 is melt | fused so that the extraction tool 5 may be integrated after die cutting.
In this state, since the opening 8 is still left at the upper end of the foaming packaging bag 10, the inner solution 7 and the sponge 6 are put through the opening 8, and then the opening 8 at the upper end is sealed.
In addition, after putting sponge 6 in the foaming packaging bag 10 first, the content 7 may be filled from the opening part 8, or the content 7 may be filled from the extraction tool 5. FIG.

As the contents 7, it is possible to appropriately select a liquid or a fluid that can be suitably used by foaming, such as detergents such as hand soaps, facial cleansing foams, hair shampoos, body shampoos, dishwashing detergents, cosmetics, foods or pharmaceuticals.
In addition, the foaming packaging bag 10 of the present embodiment is composed of a film having an outer size of 100 mm in width after die cutting and 160 mm in height (29 mm in the fold portion therein), and stores 80 ml of hand soap. ing.

  In the lathering packaging bag 10 of the present invention configured as described above, the contents 7 absorbed by the sponge 6 are sufficiently lathered by grasping the storage part 4 that is not bulged and gripping by hand. Thereafter, the cap 5a is removed, and the foamed contents 7 can be taken out from the pouring tool 5 and used conveniently.

  In addition, in the modified example of the foaming packaging bag 10 shown in FIG.3 and FIG.4, since the holding hole 9 which can insert and hold | maintain the said cap 5a is provided in the lower end part both sides, loss of the cap 5a is prevented. Convenient to use as a dispenser.
