Description

[Detailed description of the invention]

[0001]

This invention is such that when the opening / closing lid is rotated from the packaging container body in the opening direction, it can be stopped at each stage of opening, and the opening limit is regulated. The present invention relates to a packaging container.

[0002]

2. Description of the Related Art Hitherto, many packaging containers with lids made of flexible paper stock have been proposed, but all of them are inconvenient in handling because the opening and closing state of the lid is unstable. I was feeling.

[0003]

SUMMARY OF THE INVENTION The present invention is intended to solve the conventional inconvenience in use, in which the opening / closing lid is stopped at an arbitrary opening and the opening limit is limited. Is what you do.

[0004]

That is, the present invention consists of a flexible stock (1), a rectangular bottom wall (2), and a front wall (3) and a rear wall (3) connected before and after it. 4), a fixed top wall (5) connected to the front wall (3) and covering only the front part of the top surface, and a part of the fixed top wall (5) connected to the rear wall (4). The movable top wall (6) which is to be overlapped to form the opening / closing lid is linearly arranged so as to be bent at the joint fold, and the rising wall (7) is provided on both sides of the bottom wall (2). And movable side walls connected to both sides of the front wall body (3) and the rear wall body (4) with adhesive walls (8, 9), respectively, and connected to both sides of the movable top wall body (6). The body (10) has an arc-shaped edge (1) whose radius is the distance from the connecting fold to the movable top wall body (6) and whose center is the end point of the connecting fold.
6) is formed, a locking projection (17) is formed at the end of the edge (16), and furthermore, a connecting fold with an adhesive wall (11) connected to both sides of the fixed top wall (5). The edge (13) of the fixed top wall (5) of the cut and raised piece (21) connected to the fixed top wall (5) in a part of the eye and the top edge (12) of the adhesive wall (11). Edge (2) closer to the intersection (14)
The distance from 1A) to the intersection (11P) between the top edge (11A) of the adhesive wall (11) and the top wall (12) is determined by the connection between the movable side wall (10) and the movable top wall (6). Crease (6
A) is substantially equal to the distance of A), and thus the side wall body (10)
The movable top wall (6) constituting the opening / closing lid in a state where the rising wall body (7) and the respective adhesive wall bodies (11, 9, 8) are sequentially superimposed and bonded to each other to form a packaging container, ) Is rotated in the opening direction, the arc-shaped edge (16) slides along the cut-and-raised piece (21), and at the end thereof, the locking projection (17) is connected to the cut-off edge (17). Piece (2)
The present invention proposes a packaging container capable of maintaining the open state of the opening / closing lid, which can be abutted in 1).

[0005]

In the packaging container of the present invention having the above structure, when the opening / closing lid constituted by the movable top wall is opened after being assembled from the flexible stock, the movable top wall is opened. Since the arc-shaped edge of the movable side wall body connected to both sides slides along the cut-and-raised piece protruding on both sides of the fixed top wall body and opens, it can be stopped at any open angle, and The opening operation is limited by the stop lip.

[0006]

FIG. 1 is an exploded view of the packaging container of the present invention shown in FIG. 1. A flexible stock 1 has a rectangular bottom wall 2, a front wall 3 and a rear wall 4 connected to the front and rear thereof. A fixed top wall 5 which is connected to the front wall 3 and covers only the front portion of the top surface, and a movable top which is connected to the rear wall 4 and partially overlaps the fixed top wall 5 to form an opening / closing lid. The wall body 6 and the wall body 6 are arranged in a straight line so as to be bent at the joint fold of each other. In addition, not only between the above-mentioned respective wall bodies but also between the respective wall bodies to be described later, connecting folds are indicated by dotted lines, and the folds can be made through these folds.

A rising wall 7 is connected to both sides of the bottom wall 2 and adhesive walls 8 and 9 are connected to both sides of the front wall 3 and the rear wall 4, respectively. The movable side wall body 10 connected to both sides is connected to the movable fold wall 6 of the movable top wall body 6.
A is the radius of A, and the connecting fold 6A, an arc-shaped edge 16 centered on an end point 15 of the connecting fold 6B of the rear wall 4 and the movable wall 6, and an arc-shaped edge 16 And a locking projection 17 protruding from the end of the head. Further, a cut-and-raised piece 21 connected to the fixed top wall 5 is protruded from a part of a connecting fold 14 of the adhesive wall 11 connected to both sides of the fixed top wall 5. The cut-and-raised one edge 2 closer to the intersection 14 between the edge 13 of the fixed top wall 5 and the top edge 12 of the adhesive wall 11
The distance from 1A to the intersection 11P between the side edge 11A of the adhesive wall 11 and the top edge 12 is substantially equal to the distance of the joint fold 6A between the movable side wall 10 and the movable top wall 6. .

At the front end of the movable top wall 6, an adhesive edge 18 to the fixed top wall 5 is formed, and connected to the adhesive edge 18 to coincide with the edge 13 of the fixed top wall 5. Edge 1
9 to form an open resection piece 20 comprising

In the above configuration, first, the bonding edge 18 is bonded to the fixed top wall body 5 to form a square sleeve, and then a predetermined content such as food is packed from any open side. After that, the movable side walls 10, 10 are folded, and then the rising walls 7, 7 on both sides of the bottom wall 2 are raised (hereafter, since only the left and right are the same, only one of them is instructed to avoid complexity). Then, the adhesive wall 11 of the fixed top wall 5 is bonded to the rising wall 7, and the adhesive wall 9, the adhesive wall 8
2 and glued to each other with an adhesive.
Build up like.

At the time of opening, if the cut-away piece 20 is peeled off, the movable top wall 6 constituting the opening / closing lid is moved while the arc-shaped edge 16 is in sliding contact with the cut-and-raised edge 21A. The body 6 can be stopped at a desired degree of opening, and the degree of opening is limited by the engagement of the locking projection 17 against the edge 21A. FIG. 3 shows this state.

[0011]

According to the packaging container of the invention,
Since the open state of the opening / closing lid can be maintained at an appropriate degree of opening and the limit of opening is restricted, there is an effect that handling and use of this kind of packaging container becomes extremely convenient and comfortable.
