Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a packaging box in which can containers, such as cans, having convex parts such as seams on the peripheral edges of the lid and bottom are fixed to the side wall. It is.

[Problems to be solved by conventional technology and ideas]

Conventionally, canned goods and the like are packaged using a top-opening packaging box with four side walls, in which the cans and the like are packed side by side, but when displaying or transporting the cans, etc., there is an inconvenience that they may fall out of the box due to overturning. The object of the present invention is to solve this problem and provide a packaging box for canned goods, etc., in which the can container can be fixed to the side wall.

[Means to solve the problem]

The present invention provides a locking tongue piece having an arcuate tip facing downward on at least one of the opposing side walls of the packaging box, and furthermore, the tip of the locking tongue piece is made to protrude inward of the packaging box. The device securely engages the convex portions on the periphery of the lid and bottom of the can container, thereby fixing the can inside the box.

That is, in the present invention, in a top-opening packaging box consisting of four side walls, at least one of the opposing side walls is composed of an outer plate 4 and an inner plate 5,
A locking tongue piece 7 having an arc at the tip is formed facing downward on the inner plate 5, and an insertion piece 8 is inserted between the tip of the inner plate 5 and the locking tongue piece 7. This is a packaging box for canned goods, etc.

〔Example〕

Hereinafter, the present invention will be specifically explained with reference to the illustrated embodiment. FIG. 1 is a developed view of the invention, in which an outer gable plate 2 and an inner gable plate 3 are respectively extended on the left and right sides of the bottom plate 1. An outer plate 4 and an inner plate 5 are extended, and flaps 6 are provided on the left and right sides of each outer plate 4 and inner plate 5, respectively. Next, on at least one of the inner plates 5, a locking tongue piece 7 having an arcuate tip is appropriately formed facing outward, and an insertion piece 8 is extended. Note that various shapes of the locking tongue piece 7 can be used as shown in Fig. 2 A, B, and C.
Any shape may be used as long as it has an arc at the tip.

The flat blanks constructed as described above are assembled to form a packaging box. First, the tip of the inner plate 5 is bent inward as shown in FIG. The insertion piece 8 is placed between the tip part of the inner plate 5 and the locking tongue piece 7 so as to be overlapped with the tip part of the inner plate 5. By extending this insertion piece 8 to the inner plate 5, accessories are eliminated and manufacturing and storage before assembly is facilitated, but a separate piece separated from the inner plate 5 may also be used. . Thereafter, it is assembled in a conventional manner to form a packaging box with an open top and four side walls as shown in FIG.

FIG. 5 shows a state in which a can container A such as a canned food is stored in this packaging box. In this state, the locking tongue piece 7 engages with the tip of the inner plate 5 as shown in FIG. Insert piece 8 inserted between stop tongue piece 7
As a result, the tip thereof protrudes inward, and it catches on the convex portion of the lid periphery of the can container A, so that the can container A is securely locked and fixed by the inner plate 5. In the illustrated embodiment, the locking tongue piece 7 is formed only on one inner side plate 5, but the locking tongue piece 7 is similarly formed on the other opposing inner side plate 5. Can container A can also be fixed by both the lid and the bottom.

The present invention not only provides the locking tongue piece 7, but also inserts an insertion piece 8 between this and the tip of the inner plate 5 to make the tip of the locking tongue 7 protrude. Therefore, can containers such as canned goods are securely locked and fixed in the packaging box.

[Effect of the invention] This prevents the can container from falling out of the packaging box even if the packaging box is turned upside down. For example, as shown in FIG.
The can containers are stored in both the body box 9 and the lid box 10, and the packaging box is opened and closed by moving the lid box 10 as shown by the arrow. It can also be used as a so-called book-type packaging box.
