Abstract

PROBLEM TO BE SOLVED: To provide a novel packaging bag apparatus for a product which is needed to be tightly closed (sealed) until it is used. SOLUTION: Contents which need tight closing until being used such as fragrance 3, dehumidifier, insecticide, deodorizer, detergent, freshness holding agent, disinfectant and fomentation are put between a surface piece 1 comprising an air permeable material such as a porous film, nonwoven cloth, and paper and a rear piece 2 comprising a non-permeable material such as a synthetic resin film, entire peripheral rims of the surface piece 1 and the rear piece 2 are fixed with such a strength that force of fingers cannot peel off and airtightly to each other, and also a cover piece 4 comprising a non-permeable material such as a synthetic resin film is overlaid on an exterior of the surface piece 1, while the entire peripheral rim of the cover piece 4 is fixed to the entire peripheral rim fixed part of the surface and rear pieces with such a strength that force of fingers can peel off and airtightly.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag device for packaging goods which needs to be kept in a closed state until immediately before use.

[0002]

2. Description of the Related Art Packaging of a product which needs to be kept in a sealed state until just before use is wrapped in a permeable inner bag in a non-permeable outer bag which is torn off immediately before use. It was a so-called double package. In this way, double packaging has defects such as high cost and low productivity for the manufacturer, and for the consumer when there are many pieces in the outer package. However, there is an inconvenience that, for example, there is a problem in that if the remainder appears, it may be difficult to save it.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a novel packaging bag apparatus which solves the above-mentioned defects and disadvantages.

[0004]

In order to achieve the above object, a packaging bag device according to the present invention comprises a front piece made of a permeable material such as a perforated film, a nonwoven fabric and paper and a non-permeable material such as a synthetic resin film. Put the contents that require airtightness until the use of fragrance, dehumidifier, insecticide, deodorant, detergent, freshness preservative, bactericide, compress, etc. between the back piece consisting of The entire peripheral edge of the front side piece and the back side piece are firmly fixed to each other with a strength that cannot be peeled off with the force of fingers and airtight, and a cover piece made of a non-breathable material such as a synthetic resin film is polymerized outside the front side piece. The entire peripheral edge portion of the cover piece is air-tightly fastened to the entire peripheral fastening portion of the front and rear side pieces with a strength that can be peeled off with the force of a finger.

[0005]

Since the packaging bag device according to the present invention has the above-described configuration, the cover pieces are peeled off with the fingers and the divergent substances radiated from the contents such as the fragrance are discharged from the ventilation portion of the front side piece. It may be provided by use such as putting it out.

[0006]

The packaging bag device according to the present invention can be manufactured at low cost because the manufacturer can manufacture the packaging bag device by fastening the entire circumference of the front side piece, the back side piece and the cover piece. It can be done with high productivity, and the consumer can easily use it by just removing the covering piece just before using it. It can be put into a usable state, and it is possible to solve the problem that the storage of the remaining items is troublesome as in the above-mentioned conventional example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in the figures, a fragrance 3 is put between a front side piece 1 made of a synthetic resin perforated film and a back side piece 2 made of a synthetic resin non-porous film. The entire periphery is welded to each other, and a cover piece 4 made of a synthetic resin film is superimposed on the outside of the front side piece 1.
It is airtightly fastened to the entire periphery fastening portion of the back side pieces with an adhesive 5 having a strength capable of peeling off with the force of a finger.

In the present invention, when the entire periphery of the front side piece 1 and the back side piece 2 is welded, one side is not welded, and the contents are put in from here as an opening, and then the opening is closed by welding. There is.
