Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to bags.

[Conventional Conventional]

BACKGROUND ART Various types of bags are known that can be restored to the old sheet form, which are formed by folding a sheet-like base material into a square bag shape and fixing handles to the bag.

[Problem that the invention attempts to solve]

However, in these known types, the means for holding the sheet-like base material in the shape of a rectangular bag and the means for fixing the handle to the bag are separate, so the structure is complicated and the bag is There were problems such as double effort was required to maintain the shape and to attach the handle.

[Means for solving problems]

The present invention has a rectangular rectangular parallelepiped shape with length (L) x width (W) x depth (D), and a bottom part with a rectangular shape of (L) x (W), and a front side of this bottom part. A front part and a rear part exhibiting a rectangle of (L) x (D) are connected to the edge and the rear edge via a folded line, and a front part and a rear part having a rectangle of (L) x (D) are connected to the left edge and right edge of the bottom part via a folded line. A left side part and a right side part exhibiting a rectangular shape of W) x (D), and (D) x (D) connected to the left edge of the front part and the front edge of the left side part via a folding line.
A left front ear part having a square shape, a right front ear part having a square shape of (D) x (D) connected to the right edge of the front part and the front edge of the right face part via folding lines, and the left side of the rear part. A left rear ear section having a rectangle of (D) x (D) connected to the edge and the rear edge of the left side through a folding line, and a folding line on the right edge of the rear side and the rear edge of the right side. (D) A narrow rear folded part connected via a folding line,
The base material is made of paper or synthetic resin, which consists of a narrow left folded part continuous to the upper edge of the left face part, and a narrow right folded part continuous to the upper folded edge of the right face part via a bend. A left front hole that communicates inside and out with the front part, the left front ear, and the front folded part; a right front passage that communicates inside and out with the front part, the right front ear, and the front folded part; A left rear passage hole that communicates with the inside and outside of the left rear ear part and the rear folded part, and a left rear passage hole that communicates with the rear part and the right rear ear part with the inside and outside, and furthermore, Arrange a short rod shaft on the outside of the part and the rear folded part, and connect both ends of the front rod shaft to the left front through hole and right front through hole.Similarly, both ends of the rear rod shaft are connected to the left rear through hole and right rear through hole To provide a bag in which the front rod shaft and the rear rod shaft can be horizontally mounted by inserting the front rod shaft and the rear rod shaft into each other, and both lower ends of an inverted U shape can be freely connected to the center portion of the front rod shaft and the rear rod shaft. This is an attempt to solve the above problems.
