Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bottom-

The present invention relates to a floor-mounted shopping bag and a method of manufacturing the same, which is constructed as a unitary bottom surface to improve durability and to facilitate manufacture and storage.

Generally, a shopping bag is formed so as to have a substantially rectangular parallelepiped inner space by folding a single material and attaching necessary portions, and the outer shape of the shopping bag is almost the same as that of only the width, the height, and the handle.

BACKGROUND ART [0002] Shopping bags are usually made of synthetic resin such as polyethylene or paper. When they are made of synthetic resin, collecting and recycling are not easy. Especially, they have a problem of environmental pollution during disposal.

On the other hand, in the case of a general shopping bag made of paper, when the load of the object stored in the inside is heavy, the adhesive portion of the bottom surface is easily separated, so that the shopping bag is damaged, and the stored object is damaged or lost.

In addition, since the folding line is formed on the lower side of the back side of the shopping bag for storing or loading the shopping bag, the bottom is folded toward the rear side, so that the rear side printing area for advertising or the like is restricted by the folding line, The surface of the shopping bag is easily damaged in the loading process as the bottom of the other shopping bag is inserted between the folded bottom and the back surface of the shopping bag when the plurality of shopping bags are stacked, .

In addition, in the use of the folded shopping bag, since the operation of stretching the folded bottom portion and then putting the hand into the inside of the shopping bag so that the inside is opened must be performed, the use of the shopping bag is simple There was a problem.
