Description

[Detailed description of the invention] The present invention relates to a document case made of portable paper, etc., and is designed to make it easier to see the contents, to make it easier to take in and out the contents, and to make opening and closing operations quick and easy. The purpose of this bag is to make it easier to use, to make it look better than paper bags, and to make it simpler.

The present invention aims to achieve the above-mentioned purpose, and is to integrate folding plates on both the left and right edges of the front and rear side plates, which are connected together at the lower edge so that the whole can be folded and stacked in half using cardboard material. In addition, a cardboard document storage bag forming member similar to the above, which is equipped with a fold-up edge plate on the inside of the lower edge, is placed on the inside of the front and rear side trial parts, and these forming members The left and right edges of the folding plate are inserted into the inside of the above-mentioned left and right folding plates, and a string passage hole is formed to penetrate inside and outside of the folding plate at the upper and lower positions of the vertical line that straddles the outer edges of the folding plate. The order in which the rubber string crosses the outer edge is to pass through the string passage hole for each unit, and the rubber string is attached to both ends with short horizontal rods with pointed ends that function as sewing and bolts. Both ends of the forming member are fastened to the folding plate by inserting it through the board and locking the horizontal rod inside in a bolt-like manner, and by this fastening, a document storage bag portion is attached to the inside of the forming member. The capacity of the bag part can be increased or decreased by expanding and contracting the elastic string, and handles are provided at the upper sides of the front and rear plates in mutually corresponding positions, and A pair of through-holes provided at both ends of the upper side. By inserting both ends of the rubber string from the outside and forming a knot at the inwardly protruding portion caused by this insertion, the rubber string is attached to the outside of the rear panel. The main idea is to maintain the folded state of the front plate and the rear plate using the tensioned rubber strings.

Next, an embodiment of the present invention will be described with reference to the drawings. Two parallel bendable parts 3, 3' are made of cardboard material.
The front plate 1 and the rear plate 2 are integrally connected at the lower edge so that the whole can be folded in two through the The folding plates 4 and 4' are integrally connected through the wires, and a folded edge is provided inside the lower half of the front plate 1 and the rear plate 2, which is approximately the same size as the lower half and is inside the lower edge. Cardboard document storage bag forming members 6, 6' similar to those described above are provided with plates 5, and the left and right edges of these forming members 6, 6' are attached to the above-mentioned left and right folding plates 4, 4'. It penetrates into the inside of the forming members 6, 6' and the folding plates 4, 4', and penetrates inside and outside at the upper and lower positions of the vertical lines that straddle the outer edges 7 of the folding plates 4, 4'. Drill string holes 8, 8', 8'',
Separately from this, a rubber string 10 of a predetermined length is constructed, with short horizontal rods 11 having pointed ends and having a sewing function and a bolt function attached to both ends.
string passage holes 8, 8' for each unit that straddles the outer edge 7,
Both ends of the forming members 6, 6' are attached to the folding plate 4 by inserting the rubber strings 10 through the outer edges 8'' in the order of crossing the outer edge 7 and locking the horizontal rods 11 in a bolt-like manner on the inside. . In addition, finger insertion holes 14, 14' are opened at mutually corresponding positions on the upper sides of the front plate 1 and rear plate 2, and holding hands 15, 15' are provided. Also rear version 2
A pair of through holes (not shown) are provided at both ends of the upper side, and both ends of the rubber cord 17 are inserted from the outside into these through holes, and the inward protruding portion of the through holes is used to tie the ball 1.
8, 18', the elastic cord 1 is
7 is tensioned on the outside of the rear plate 2, and the state in which the front plate 1 and the rear plate 2 are folded in half is maintained using this tensioned rubber string 17.

The present invention is as described above, so the purpose is to make it easier to see the contents, to make it easier to take in and out the contents,
It has the effect of fully achieving the objectives of making opening and closing operations quick and easy, making it more aesthetically pleasing than paper bags, and making it simpler.
