Abstract

(57) [Summary] [PROBLEMS] To make it possible to fold the bottom of a paper or plastic handbag without bending it to the front or the back, and to make no folds on the front or the back, and separate the sides. It is possible to give a taste to colors and designs by using the fabric of the present invention, and to provide a paper or plastic carrying bag as a high-quality product. A square or rectangular front plate and a back plate and a bottom plate of the same shape and size as the front plate are folded up so as to form an upward U-shape. The bottom plate and the left and right side plates are provided with a middle folding line so as to bend inward along the entire length of the center, and glue strips on both sides of the side plate, The problem is solved by coupling the bottom abutment to the lower end and forming a triangular abutment surface on the bottom abutment below the side plate.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrying bag made of thick or thin paper or plastic panel.

[0002]

2. Description of the Related Art A conventional paper carrying bag is generally shown in FIG. FIG. 5A is an overall view thereof, and FIG. 5B shows a folded state.

[0003]

Such a conventional paper carrying bag is entirely made of one continuous sheet of paper, and is particularly thickly folded like a single sheet by folding back and forth on the bottom surface 31 and right and left. In addition, the left and right side surfaces 32.33 are formed in a series with the front surface 34 and the back surface 35 so that a center folding line is provided on the side surface so as not to be bulky when folded. But,
Since the bottom surface cannot be folded due to the middle fold line and batting on the side surface, the bottom surface is folded toward the front surface (or the rear surface) and overlapped. Therefore, the next time the bag is opened, a folding line 36 appears on the front (or rear) portion as shown in FIG.
There is a problem that it significantly impairs the appearance. Further, since the bag is formed by bending a single sheet of paper, the entire bag is monotonous without any change, giving a sense of cheapness, and thus has the problem that it does not come out of the disposable area.

[0004] The present invention has been made in view of such problems of the prior art, and an object of the present invention is to fold the front plate or the back plate without bending the bottom portion so as to overlap the bottom plate.
In addition to making it possible to fold it in a middle fold type so as not to cause batting with the side parts, and to improve the appearance by preventing the folding line from appearing on the front or back version, the side parts are separate fabrics The purpose of the present invention is to provide a color or a design with a taste, and to provide a paper or plastic carrying bag as a simple, inexpensive and high-quality product.

[0005]

In order to achieve the above object, a bag for packaging according to the present invention comprises a square or rectangular front plate, a rear plate and a bottom plate having the same shape and the same size as the front plate. It is a handbag that is formed by laminating side plates on the left and right sides integrally to the bag main body that is formed by folding up so that it becomes a letter shape. Along with providing a middle folding line so as to bend, glue margin pieces on both sides of the side plate, a bottom contact at the lower end, and a triangular folding surface to the bottom contact at the bottom of the side plate It becomes.

In addition, the bottom plate and the bottom plate of the side plate are
The problem is solved by integrally joining the engaging claw formed on one surface by the engagement of the corresponding engaging hole with the engaging claw.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS When a bag in an opened state is folded, the front plate and / or the back plate are pressed inward. Then, the bottom plate and the left and right side plates are folded inward at the center line at the center, and at the same time, the triangular folding surfaces at the bottom of both plates are folded from a plane into two triangles and overlap the surface of the bottom plate. So that it adheres to the curved surface. This makes it possible to cope with the middle fold of the bottom plate without batting the middle fold of the side plate. Therefore, since the bottom plate can be bent in a V-shape from the center between the front and back plates, no fold is formed at any position of the front plate or the back plate.

When the bag is opened, if the front plate and the back plate are pushed outward, the left and right side plates and the bottom plate are bent at a straight line so that the bag can be opened at a stretch. it can.

【Example】

An embodiment will be described below with reference to the accompanying drawings. As shown in FIGS. 1 and 3, the front plate 1 and the rear plate 2 are horizontally long rectangles having the same shape and the same size, and these plates and the bottom plate 3 are formed in series. Then, the front plate 1 and the back plate 2 are vertically folded to form an upward U-shaped bag main body 10. At the center of the bottom plate 3, a middle folding line a composed of a fold parallel to the longitudinal direction is provided.

A side bag 4.5 is integrally attached to the left and right open portions of the bag main body 10 to form a handbag.

Since the side plate 4.5 is bilaterally symmetric, FIG.
The left side plate 4 will be described. As shown in FIG. 4, the side plate 4 has the same width as the bottom plate 3 and is provided with a series of glue pieces 41 on both sides and a bottom contact piece 42 bent at a right angle at the bottom. A center folding line b is provided at the center of the side plate 4 and the bottom abutment 42 so as to be bent inward. In addition, a chevron fold line c. A triangular abutment surface 43 surrounded by d and a bottom line e is formed. Middle folding line b and chevron crease line c. d is a mountain fold, but a bottom line e and a middle fold line b 'crossing the triangular surface are valley folds. The bottom plate 42 is the bottom plate 3
Although it is bent inwardly in an integrated manner while overlapping on the surface of, the locking claw 6 is locked in the engaging hole 7 during assembly so as not to be separated. Locking claw 6 is bottom plate 3
The engaging hole 7 is formed as a slit hole in the bottom contact piece 42 of the side plate.

The side plate 4.5 is formed by bending glue margins 41.51 integrally formed on both sides outwardly at right angles and fitting them on the left and right sides of the bag body 10 so as not to be separated as a whole or by spot welding 8. Join. When disassembly is possible, instead of welding 8, a hook or other engaging means is used.

A hand 9 is attached to the bag body 10. The bag body 10 and the left and right side plates 4.5 can be made of paper or plastic sheets or panels, and the bag body 10 and the side plates 4.5 can be formed of the same or different materials. Also,
The texture and color can be changed depending on the material.

[0014]

According to the present invention, the left and right side plates and the bottom plate are bent inward when the bag is folded flat, and the lower part of the side plate is bent. Is folded while the triangular folding surface overlaps the surface of the bottom plate, so that the so-called loose batting does not occur, so that the front plate and the back plate can be kept in their original form without any folds.
Further, since the side portion is made of a material separate from the front, back and bottom surfaces, it is possible to change the color, the taste in design, and the thickness. Therefore, it is possible to provide a conventional paper bag with a cheap feeling of disposable as a high-grade product.

Further, since the present invention is configured as described in claim 2, the bottom plate of the bottom plate and the side plate are integrated by the locking claw and the engaging hole so that the bottom plate is formed. Immobilization can be promoted, and durability can be improved in terms of strength.
