を与えたものである。``Prior art'' Conventionally, adhesive is applied to the opening step consisting of the high and low edges of a cylindrical bag with double pleats, and this is folded back to the front side of the bag to apply the adhesive on the opening step to the paper surface on the front side of the bag. There were things that could be sealed by gluing them (Utility Kai 58-
No. 73735). However, since the adhesive on the opening step is directly adhered to the paper surface of the bag, when the bag is opened by weight extrusion of the contents, the pieces of paper at the adhesive part peel off together with the adhesive, and the peeling paper pieces separate from the contents. (flour, etc.) and caused significant damage to the commercial value of the contents.

る。``Means for Solving the Problems'' The present invention is a double pleated cylindrical bag consisting of an inner layer and an outer layer, in which an opening step is formed by the lower edge on the front side of the inner layer and the higher edge on the back side of the outer layer, and the lower edge on the back side of the inner layer is formed into an opening step. The outer surface and the inner surface of the back side of the outer layer are sealed with an adhesive, and the adhesive is applied to the outer surface of the inner layer surface and the inner surface of the back side of the outer layer using the lower edge of the front side of the inner layer as a boundary, and the opening at the boundary is closed with the adhesive. It is made up of an open bag that is sealed and the adhesive-applied part is folded back to the outer layer surface side.

することなく内容物は同開口部から排出される。"Operation" Therefore, the adhesive application part and the opening stage are developed from the folded part. In this state, the lower edge on the front side of the inner layer and the higher edge on the back side of the outer layer are connected and sealed by the adhesive as shown in Figure 2, and the contents do not leak out from the opening. . In this state, when the bag is turned over so that the opening is facing downward, the weight of the contents will cause the connection part of the adhesive to be separated along the lower edge of the front side of the inner layer, causing the paper pieces of the bag to peel off. The contents are discharged from the same opening.

A decorative paper 8 is pasted on the back side of the outer layer, a part of which extends upward as shown in FIG. 1, and a cut tape 9 is pasted on the inside surface extending over both sides of the high edge 4 of the back side of the outer layer. Then, an adhesive 6 is applied to the outer surface of the inner layer front side and the inner surface of the back side of the outer layer with the lower edge 3 of the front side of the inner layer as a boundary. A rubber adhesive is used as the adhesive 6, but a vinyl acetate adhesive may also be used. The parts coated with the rubber adhesive adhere to each other, but the adhesiveness between the rubber adhesive 6 and the paper surface is quite weak and the adhesive is easily peeled off. The outer surface of the lower edge 4' on the back side of the inner layer and the inner surface on the back side of the outer layer are sealed with an adhesive 6'. The boundary portion is an opening 7 of the inner bag, as shown in FIG. 2, and the opening 7 is sealed so as to be connected with the adhesive. Then, the application part, the opening step 5 and the decorative paper 8 are folded back toward the front side from the folding line a along the lower edge of the application part, and the application part has many dotted paper surface exposed parts of the release agent 10 applied to the front side. 11 in an easily releasable manner, and the decorative paper 8 is sufficiently adhered to the front paper surface with an adhesive 12 and sealed.

開封袋が得られるものである。"Effects" Since the present invention is constructed as described above, there is no risk of the contents leaking out from the opening 7 along the lower edge 3 when the product is folded back from the folding line a and one end is sealed, and when the package is opened. The adhesive 6 that connects the lower edge on the front side of the inner layer and the higher edge on the back side of the outer layer of the opening 7 is divided by the weight of the contents and opens, so the paper strips of the bag peel off together with the adhesive and the contents are separated. A high-quality opening bag is obtained in which release paper pieces do not get mixed into the bag and the adhesive 6 can be easily opened by the weight of the contents.
