[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging box for storing tablets, vials or any other articles packed in a press-through pack, and more particularly to a method for easily breaking a packaging box when discarding it. The present invention relates to a packaging box which can be discarded in a flat state without bulk.

[0002]

2. Description of the Related Art Conventionally, as a packaging box for accommodating various articles, for example, as shown in FIGS. 7 and 8, there is a packaging box formed by assembling a paperboard or a corrugated paperboard. That is, this packaging box (50) is composed of four side plates (51, 52, 53)
(54), a body (55), a lid (56) connected to the periphery of the upper end opening of the body (55), and each side plate (51, 52, 53, 54)
And bottom flaps (57, 58, 59, 60) connected to each other. That is, the bottom portion (61) is formed by bonding bottom flaps (57, 59) protruding to the lower portions of a pair of side plates (51, 53) adjacent to each other, and another pair of bottom flaps ( (58 ・ 60)
It is formed by engaging with and connecting with. Also, inside the packaging box (50), a partition plate (62) is provided so that the vials and the like to be accommodated do not collide with each other.
2) is constructed so as to be connected to the inner surface of the side plate (51, 52, 53, 54) so that the packaging box can be assembled by a simple operation.

The packaging box (50) is made of thick paper so as to prevent the contents from being spilled due to the bottom being pulled out during the handling process, or the boxes being broken during stacking and damaging the contents. It is.

[0004]

[Problem to be Solved by the Invention] The above packaging box (50) is bulky in a three-dimensional state when it is stored, and when the packaging box is discarded because the contents are exhausted, such as when the contents are exhausted, it is necessary to break the packing box into a flat state. However, it cannot be easily broken because it is formed firmly because of the need to protect the contents during handling. In particular, in the packaging box with a partition shown in FIGS. 7 and 8, there is a problem that the partitioning plate (62) disposed in the packaging box (50) acts as a reinforcing material, so that it is harder to break.

To solve this problem, for example, as shown in FIG. 9, unbonded portions (64, 64) of the bottom flaps (57, 58) located at the lowermost layer are located closer to the tip than the bonded portions (63, 63). ) Is provided, and the non-adhered portion (64) is pinched with a finger to peel off the adhesive portion (63), whereby the bottom is pulled out and the packaging box (50) may be broken. However, the adhesive portion (63) is adhered with sufficient strength so that the bottom portion (61) does not fall off due to the weight of the contents. The paper material itself of the flaps (57, 58) breaks into layers, and there is a possibility that a part of the bottom flap (57, 58) remains in the adhesive part (63) and the packaging box (50) cannot be easily broken. .

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a packaging box which can be reliably broken into a flat state with a simple operation and which can maintain a high strength during use.
