[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging bag, and more particularly, to a packaging bag that can prevent an article from being scratched due to impact or rubbing and can efficiently package the article.

[0002]

[Prior art and its problems]

 Generally, when carrying electronic parts that are sensitive to shocks or plastic products that are easily scratched on the surface, put them in a plastic bag, wrap it with a cushioning material, and then put it in a cardboard box or the like. I try to carry it.

When packaging such an article that is easily scratched, it is necessary to put it in a bag, wrap it with a cushioning material, and handle the article carefully, which takes time to work. There is such a problem.

[0004]

[The purpose of the device]

 The present invention has been made in view of the above-mentioned conventional problems, and it is an object of the present invention to provide a packaging bag that can quickly package an article and can sufficiently protect the article against impact and rubbing. To aim.

[0005]

[Key points of the device]

 According to the present invention, an outer bag is formed of a material having a cushioning function, an inner bag is formed inside the outer bag, and the outer bag and the inner bag are fixed together on both sides. This is achieved by providing a packaging bag characterized by being worn.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing a packaging bag of the present invention.

In FIG. 1, the packaging bag 1 is provided with an outer bag 2 and an inner bag 3 located inside the outer bag 2. The outer bag 2 is an air-granule (hereinafter simply referred to as an air-granule) 2a in which two thin films of plastics such as vinyl, polyethylene, polypropylene and the like, which are spread, are wrapped on one side of these thin films of plastic. It is formed of a sheet with a large number of bulges. Then, the cushion function is exerted by the large number of air granules 2a. The inner bag 3 is made of a plastic film.

Both sides connecting the both ends of the opening side 4 of the outer bag 2 and both ends of the bottom side and both sides connecting the both ends of the opening side 5 of the inner bag 3 and both ends of the bottom side are the extension of the inner bag 3 described later. They are welded together except the protrusion. Further, the bottom side of the outer bag 2 and the bottom side of the inner bag 3 are not fixed to each other and are kept close to each other.

In this embodiment, the air granules 2a of the outer bag 2 are arranged to project to the outside of the outer bag 2, but conversely, the air granules 2a are formed in the outer bag 2. It is also possible to make the sheet bulge inward and to place the flat sheet on the front side.

Both sides on the opening side of the inner bag 3 are slightly (30 mm to 50 mm) longer than that of the outer bag 2 to form an extension portion 6, and both sides of the extension portion 6 are formed. The sides are welded. The extending portion 6 may be omitted, and both sides of the inner bag 3 and the outer bag 2 may have substantially the same length to form a packaging bag.

The manufacture of the packaging bag 1 having the above-mentioned structure will be described with reference to FIG. The whole rectangular sheet is bent from approximately the center so that the sheet to be the bag 2 is on the outside and folded in half (Fig. (B)). Then, the folded sheet body is cut at a predetermined interval in the direction of arrow a with an electric heating type or high frequency type fusing device (FIG. 2 (c)). At this time, in this cutting step, the sheet is cut and the cut surface is heat-welded to form the left and right sides of the bag. As a result, the opening side 4 and the opening side 5 are automatically formed. Then, the outer bag 2 and the inner bag 3 are fastened together, and a plurality of packaging bags 1 can be easily made from a set of sheet bodies ((d) in the same figure). It should be noted that, for example, an opening sealing means having streaky irregularities may be provided near the opening side 4 and the opening side 5. Also, the outer bag 2 and the inner bag 3 may be changed in color so that it is easy to see that the bags are double layers. May be formed.

[0012]

[Effect of the device]

 As described above in detail, according to the present invention, since the inner bag and the outer bag are fastened at both sides, the article is put in the plastic bag and the whole is put in the cushioning bag. You can complete the packaging in one operation, avoiding the trouble of twice. Further, in the case where the inner bag is provided with the extending portion, it becomes possible to prevent the product from being mistakenly inserted between the outer bag and the inner bag when the product is put into the bag. Since the outer bag and inner bag are not fastened except on both sides, the outer surface of the inner bag and the inner surface of the outer bag will contact and slide even if the outer bag is rubbed against something. You can avoid scratching your items.
