[Industrial applications]

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

[0002]

[Prior Art]

 There have been many proposals for packaging containers with lids that have been assembled with flexible paper stock, but in all of them, the open / closed state of the lids is unstable, and it feels inconvenient to handle and use. It was

[0003]

[Problems to be solved by the device]

 This invention intends to eliminate the conventional inconvenience in use, to stop the opening / closing lid at an arbitrary opening, and to set a limit on the opening limit.

[0004]

[Means for Solving the Problems]

 That is, this device should be made of a flexible paper material, and should have a rectangular bottom wall body, front and rear wall bodies connected to the front and rear sides thereof, and a front part of the top surface connected to the front wall body. A fixed top wall body and a movable top wall body that is connected to the rear wall body and is partially overlapped with the fixed top wall body to form an opening / closing lid are arranged in a straight line so as to be bendable at a joint fold of each other. In addition, rising wall bodies are connected to both sides of the bottom wall body, adhesive wall bodies are respectively connected to both sides of the front wall body and the rear wall body, and the movable side wall bodies connected to both sides of the movable top wall body are connected to each other. , A radius is defined as the distance between the movable top wall and the connecting fold, and an arcuate edge is formed with the end point of this connecting fold as the center, and a locking projection is formed at the end of this edge. Further, a cut-and-raised piece that is connected to the fixed top wall body is provided at a part of the joint fold with the adhesive wall body that is connected to both sides of the fixed top wall body. From the edge of the cut-and-raised piece closer to the intersection between the edge of the body and the top edge of the adhesive wall that is connected to the fixed top wall, to the intersection of the top edge of the adhesive wall and its side edge. In the state in which the packaging container main body is constructed by projecting the distance at a position substantially equal to the radius length of the movable side wall body and polymerizing and adhering the respective adhesive walls with the side wall body inside, When the movable top wall body forming the opening / closing lid is rotated in the opening direction, the arcuate edge slides along the cut-and-raised piece, and at the end thereof, the locking edge is The present invention proposes a packaging container that can be abutted against a cut-and-raised piece and that keeps the open / close lid open.

[0005]

[Action]

 In the packaging container of the present invention having the above-mentioned structure, when the opening / closing lid constituted by the movable top wall body is opened after being assembled from the flexible paper stock, the movable top wall body is provided with the opening / closing lid on both sides. Since the arcuate edges of the movable side walls connected to each other slide open along the cut-and-raised pieces protruding on both sides of the fixed top wall, they can be stopped at any open angle and can be opened. Is limited by the stop flange.

【Example】

 In the development view of the packaging container of the present invention shown in FIG. 1, a flexible paper material 1, a rectangular bottom wall body 2, front and rear wall bodies 3 and 4 connected to the front and rear sides thereof, and the front wall body A fixed top wall body 5 connected to 3 and covering only the front part of the top surface, and a movable top wall body 6 connected to the rear wall body 4 and partially overlapped with the fixed top wall body 5 to form an opening / closing lid. Are arranged in a straight line so that they can be bent at the connecting folds. Not only between the above-mentioned wall bodies but also between each wall body to be described later, connecting folds are displayed with dotted lines between them, and it is possible to fold through these folds. .

Standing wall bodies 7 are connected to both sides of the bottom wall body 2, and adhesive wall bodies 8 and 9 are connected to both sides of the front wall body 3 and the rear wall body 4, respectively, and the movable top wall body 6 is connected. The movable side wall body 10 connected to both sides has a radius as a distance between the movable side wall body 10 and the connecting fold 6A of the movable top wall body 6, and the connecting fold 6A and the connecting fold 6B of the rear wall body 4 and the movable wall body 6 are formed. It is composed of an arcuate edge 16 centered on the end point 15 and a locking projection 17 protruding from the end of the arcuate edge 16. Further, a cut-and-raised piece 21 continuous with the fixed top wall 5 is provided at a part of the connecting fold 14 of the adhesive wall body 11 connected to both sides of the fixed top wall body 5. The edge 13A of the fixed top wall 5 and the top edge 12 of the adhesive wall 11 closer to the intersection 14 of the cut and raised piece end edge 21A to the intersection 11P of the side edge 11A of the adhesive wall 11 and the top edge 12 The distance up to this point is substantially equal to the distance of the connecting fold 6A between the movable side wall body 10 and the movable top wall body 6.

An adhesive edge 18 to the fixed top wall body 5 is formed at the front end of the movable top wall body 5, and is joined to the side edge 13 of the fixed top wall body 5 in a row with the adhesive edge 18. An open cut 20 having an edge 19 is to be formed.

In the above structure, first, the adhesive edge 18 adhered to the movable top wall body 6 is made into a rectangular sleeve state, and then a predetermined content such as food is fed from any side face in the open state. After filling up, the rising walls 7 and 7 on both sides of the bottom wall 2 are raised (the left and right have the same shape, so only one of them is indicated to avoid complication), and then the adhesive wall 11 and the movable side wall. When the body 10, the adhesive wall body 9 and the adhesive wall body 8 are stacked in this order, and the adhesive wall bodies 7, 11, 9, 8 are adhered to each other with an adhesive, they are assembled as shown in FIG.

At the time of unsealing, if the unsealed cut piece 20 is peeled off, the movable top wall body 6 constituting the opening / closing lid is moved with the arcuate edge 16 slidingly contacting the cut and raised piece edge 21A. The body 6 can be stopped at a desired opening degree, and the opening degree is limited by the engagement protruding edge 17 abutting against the cut and raised piece end edge 21A. The state is shown in FIG.

[Effect of the device]

 According to the above-mentioned packaging container of the present invention, the open state of the opening / closing lid can be maintained at an appropriate degree of opening and the limit of the opening is regulated. Therefore, it is extremely useful to handle this type of packaging container. It has the effect of being convenient and comfortable.
