Abstract

[PROBLEMS] A conventional tri-fold chopsticks bag does not provide a means for fixing a hem folded in the reverse direction to a backing paper, so that the hem easily separates from the backing paper as time passes. Often the gaps are open. In such a case, when the chopstick bag is placed on the table, the folding side of the chopstick bag rises from the table, and when the chopstick bag is held in hand, the hem hangs down. The present invention provides means for preventing, in a tri-fold chopstick bag, a hem folded back in the back direction from opening apart from the backing paper over time.
A semi-elliptical cut, that is, a claw 8 is formed in a portion of the backing paper where the end of the folded hem 11 is in contact with the backing paper so that the arc faces downward. The hem 11 is easily adhered and fixed to the backing paper by sandwiching the end sides of the eleven layers while the three layers are put together.

Description

  The present invention relates to a tri-fold chopsticks bag in which a hem portion folded in two in the reverse direction is prevented from rising away from the backing paper.

  The procedure for creating a tri-fold chopsticks bag is to first divide the short side paper width of a vertically long rectangular piece of paper into three equal parts, create a right piece, a central piece and a left piece, and then the right piece and the left piece. By folding the piece inward so that it overlaps the central knitting that becomes the backing paper, a long three-layered polymerized piece in which chopsticks can be put is created, and finally the lower end side of the polymerized piece By folding back a certain length in the back direction, an internally closed bag is obtained.

  For the overlapping piece of the folded portion formed by folding back a predetermined length from the lower end side of the long three-layered polymer piece in the reverse direction, that is, the hem, usually, there is no means for fixing to the backing paper, Immediately after being folded, it is in close contact with the backing paper, but tends to separate from the backing paper as time passes.

Japanese Utility Model Publication No. 7-21588

  The idea described in the Japanese Utility Model Laid-Open No. 7-21588 is different from the invention of the present application in the problem to be solved, but the characteristic of the conventional trifold chopstick bag is described in the publication. As described above, the tri-fold chopsticks bag described in the above publication does not have means for fixing the folded hem to the backing paper, so that the hem easily separates from the backing paper as time passes. Often the gap between is open. In such a case, when the chopstick bag is placed on the table, the folding side of the chopstick bag rises from the table, and when the chopstick bag is held in hand, the hem hangs down.

  The present invention provides a means for preventing in advance that a skirt folded back in the three-fold chopstick bag is opened apart from the backing paper over time.

  In order to solve the above problems, a method of fixing the hem to the backing paper using glue or adhesive tape is also conceivable, but (1) using only glue or adhesive tape for one layer of three-layer polymerization When fixed on the back side, the remaining two layers of paper will be rolled up or folded. (2) Additional materials such as glue or tape are required. (3) The hem is fixed to the back side using glue or adhesive tape. Then, when the three-fold chopsticks bag is spread and reused as a laying paper or the like, there is a problem that a part to be peeled may be torn.

  Therefore, in the present invention, a semi-elliptical cut, that is, a claw is formed in the part of the back paper where the end of the folded hem is in contact with the back paper so that the arc faces downward, and the claw is provided on the claw. By sandwiching the edge of the three sides together, the hem is easily adhered and fixed to the backing paper.

  The implementation of the present invention ensures that the entire hem of the three-layered polymer structure is backed by incorporating a simple process without using additional materials such as glue or adhesive tape when creating a tri-fold chopsticks bag. Can be tightly fixed.

  In addition, the hem is not used with glue or adhesive tape, but is simply sandwiched between nails, so even after use as a chopstick bag is finished, it can be easily expanded and returned to a piece of paper, It can also be reused for laying paper.

It is a top view when developing a three-fold chopsticks bag. It is a top view when the right piece is folded back on the center piece. It is a top view when the left piece is folded over the central piece and the right piece. It is a perspective view when a hem is turned up in the reverse direction. It is a perspective view when the edge side of a hem is pinched | interposed into the nail | claw.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view when the three-fold chopstick bag is developed. The paper 1 of elongated rectangular, the short side width in three equal to form a fold 2 and 3 are formed in the longitudinal direction, by the two folds, paper 1 is the central piece 5, the right piece 6 and It is divided into a left piece 7. In addition, a crease 4 is formed in parallel with the end side 10 at a position of a length a from the end side 10. As shown in FIG. 4, the crease 4 is for folding the lower part of the three-layered polymer piece formed by folding the creases 2 and 3 in the reverse direction to form the hem 11 of the three-fold chopsticks bag.

  A semi-elliptical cut, that is, a claw 8 is formed on the center piece 5 at a position of a length a + 1-2 mm from the crease 4 in the longitudinally upward direction so that the arc is downward (see FIG. 1).

  Next, the fold 2 is folded so that the right piece 6 overlaps the central piece 5 so that the central piece 5 becomes the backing paper, and the left piece 7 is turned to the right side piece 7 so that the left piece 7 becomes the cover. The fold 3 is folded back so as to overlap the piece 6 (FIG. 2). Thereby, a three-layered polymer piece composed of the central piece 5, the right piece 6 and the left piece 7 is formed (FIG. 3). The three-layered polymer piece has an end 9 and an end 10 released.

  Finally, the lower part of the three-layered polymer piece, that is, the bottom 11 is folded back from the crease 4 (FIG. 4), and the end 10 of the bottom 11 is sandwiched between the claws 8 (FIG. 5). As a result, an internally closed bag is formed, and the hem 11 is firmly fixed to the backing paper.

Claims (1)

The paper width of the short side of a vertically long rectangular piece of paper is divided into three equal parts: a central piece, a right piece and a left piece, and the right piece and the left piece are placed inward so as to overlap the central knitting as a backing paper. In a three-fold chopstick bag formed by folding a long three-layered polymer piece produced by folding back a predetermined length in the longitudinal direction from the lower edge of the polymer piece, the polymer piece as a folded part A semi-elliptical cut (claw) is formed in the part of the backing paper where the edge of the (hem) contacts the backing paper so that the arc is downward, and the edge of the hem is sandwiched between the claws. Thus, the three-fold chopsticks bag is characterized in that the hem is closely fixed to the backing paper.
