To provide a self-standing paper bag made of kraft paper such as a rice bag and a wheat flour bag.

Abstract

To provide kraft papers for a rice bag, a flour bag or the like while maintaining strength by laminating the kraft papers in a Mokkoyo Bondo.SOLUTION: A reinforcing material is put on the side surface of the paper bag to prevent the collapse of the shape. Legs or the like are attached to the bottom surface part of the paper bag to prevent the bottom surface part of the paper bag from directly coming into contact with the floor surface.SELECTED DRAWING: Figure 4

Description

[Technical Field]

[0001] This invention relates to a paper bag, such as a rice bag or flour bag, that is made by stacking 3 to 5 sheets of kraft paper with wood glue, giving it strength and allowing it to stand stably. [Background technology]

[0002] Conventionally, as shown in the following patent document, basket-shaped bags have been made by weaving paper tapes, and the basket-shaped bags knitted in this manner are put to practical use as lightweight and durable basket-shaped bags due to the materials used. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2005-218736 Summary of the Invention [Problem to be solved by the invention]

[0004] The basket-shaped bags are made by weaving paper tape and other materials, and require considerable effort to make. [Means for solving the problem]

[0005] Kraft paper, such as rice bags and flour bags that are discarded by restaurants and other businesses, is easy to obtain.

[0006] Kraft paper, such as rice bags and flour bags, is very easy to process.

[0007] You can increase the strength of the material by cutting kraft paper such as rice bags or flour bags along the cut lines and stacking 3 to 5 sheets with wood glue. [Effects of the Invention]

[0008] In this invention, three to five sheets of kraft paper, such as rice bags or flour bags, are cut and stacked with wood glue to increase the strength and create a paper bag that can stand on its own.

[0009] By applying persimmon tannins or paint to the box-shaped surface, it is possible to create a texture and design that makes it hard to believe it is made of kraft paper.

[0010] Reinforcement material is added to the sides of the paper bag to prevent it from losing its shape.

[0011] The handles of the paper bag are made of leather or synthetic leather tape to give it a luxurious feel.

[0012] Metal fittings are attached to the bottom of the paper bag to prevent direct contact with the floor. [Brief explanation of the drawings]
