Description

[Detailed description of the invention] This invention relates to a packaging box that can be divided into two parts.

In recent years, packaging boxes have become popular in which, for example, two dozen items can be stored in one packaging box, and the packaging boxes can be divided into two packaging boxes each containing one dozen items at stores or the like, depending on the sales volume. However, when the divided packaging box is closed by applying another lid material to the cut opening, adhesive tape or clasps are required, and the plug-in type has the disadvantage that it tends to slip upward.

The purpose of this invention is to eliminate the above-mentioned drawbacks.

That is, this invention is a packaging box in which the opening of the packaging box is divided into two parts and is closed by inserting the opening to prevent it from coming out.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings. The packaging box of this invention is made of cardboard or other thick paper, and as shown in FIG. , a developable substrate a in which a bottom wall 6 is connected to the lower edges of the side wall 1 and the end wall 2 via a fold line 5, and a lid wall 7 having the same shape as the bottom wall is connected to the upper edge via a fold line 5. As shown in FIG. 1B, a folding piece 10 is connected to both ends of a rectangular lid part 8 via a fold line 9. It consists of a combination of two lid members B.

The expandable substrate a, which becomes the packaging box body A, is provided with a separation band 11 for dividing into two, consisting of a perforation or the like, in the center extending over the side wall 1, end wall 2, and glue allowance 3,
A pair of Z-shaped cuts 12 for locking the lid member B are symmetrically provided at the upper and lower ends of the separation band 11, that is, at the center of the side wall 1, and the ends of the pair of Z-shaped cuts 12 are connected to the fold line 13. are connected by Said separation band 1
1 is formed at a position corresponding to the boundary between storage tiers for bulk items, and in the case of an even number of tiers, a numeral 1 is formed at the center position.
In the case of an odd number of stages, they are provided at offset positions. In addition to the perforations, the separation band 11 may be lined with a cut tape made of polypropylene or the like or a cloth tape that is stronger than the base paper.

In the lid member B, the lid part 8 is formed to have the same shape as the cross section of the packaging box body A, and the folding piece 10 has a cutout 12 of the packaging box body A' (see FIG. 3) which is divided into two parts from the separation band 11. A mating pair of Z-shaped cuts 14 are formed. This cut 14 corresponds to the cut 12
It is formed so that the upper edge of the chevron Y just comes into contact with the upper edge of the chevron X.

The packaging box according to this invention has the above-described structure, and when this is used, two loose items, such as can-shaped drinks, are placed in the top-opening packaging box A.
A dozen is stored, and the lid wall 7 is closed and glued as shown in FIG. 2 before shipping. When dividing this into, for example, 1 dozen at a store, as shown in Figure 3,
By tearing the separation band 11, the packaging box main body A' is easily divided into two parts, and the opening of the separated packaging box main body A' is closed with a separately prepared lid member B having a U-shaped cross section. At this time, the locking piece Z defined by the pair of cuts 12 and the fold line 13 of the packaging box body A' is slightly opened outward along the fold line 13, and the folding piece 10 of the lid member B is inserted into this part.
The pair of folding pieces 10 are held together by the restoring elasticity of the material of both locking pieces Z, and the cut 12 of the side wall 1
The upper edge plate thickness surface of the chevron Y of the notch 14 just comes into contact with the upper edge plate thickness surface of the chevron X, and is prevented from coming off.

As mentioned above, according to the packaging box of this invention, the opening of the packaging box that is divided into two parts can be closed with a separately prepared lid member to prevent it from coming out with a single touch, and unlike conventional products, adhesive tape or clasps can be used to close the opening of the packaging box. This has the advantage that it is unnecessary and economical, and that it does not easily slip upwards like a simple plug-in type lid.
