2. Description of the Related Art Packaging boxes for packing assorted gifts such as beer, salad oil, soap, etc. are used to protect products, handle them during transportation, and give the products a sense of quality and weight at the time of sale. In addition, a packaging box composed of a combination of a body box and a lid is generally used. Incidentally, the body box and the cover are each configured as an assembly box which is usually formed by folding a single sheet of paper. In this assembly box, an outer plate and an inner plate constituting the side wall of the box are generally connected to each side of a quadrilateral flat plate portion through a bent curve, and the outer plate and the inner plate are connected at the time of assembly. It is folded into a heavy structure and assembled into a robust box.

[0003]

Since such a gift box is bulky, it is preferable to disassemble it as flat as possible when discarding it after use. That is, in recent years, as the environmental awareness of consumers has increased, it has been demanded that this type of gift paper box be collected and reused as resource garbage similar to used newspaper. However, since this gift paper box protects the gift even though it is assembled, even if it is an empty box, it has a high shape retention strength and has a double side wall, so just crush it. Even if it is made flat, it cannot be easily crushed, and the corners are irregularly deformed and dust is often bulky. If the box was forcibly broken, the box would be broken into several parts, and it would be unsightly, and the recovery process would be troublesome.

Conventionally, for example, Japanese Utility Model Laid-Open No. 5-89226.

Have been. The carton of the known example 1 is provided with perforated perforation lines at the four corners of the carton at the boundary between the inner side plate flap and the inner side plate, and when the box is discarded after use,
In this configuration, the inner surface of the side plate is opened outward, the perforation lines located at the four corners of the carton are cut, and the flap inserted between the inner side plate and the outer side plate is pulled out from between and disassembled into a flat shape. The cartons of Known Examples 2 and 3 each have a cutout on the lower side of the inner side plate. Further, in Known Example 2, two divergent radial fold lines are provided from the periphery of the cutout. When discarding the box after use, put the finger on the inner side plate in the notch and pull it up, make the two divergent radial fold lines provided on the periphery of the notch a mountain fold, and flatten It is configured to be disassembled into a shape.

However, the carton shown in the known example 1 is
There is a risk that the perforation lines provided at the four corners of the carton may be broken during distribution, and may be broken into a plurality of parts during disassembly. The cartons of the known examples 2 and 3 are designed so that the inner side plate is pulled up by putting a finger on the notch for finger hooking, and the inner side plate is designed to be hardly dismantled in order to maintain box strength. It takes considerable finger power to pull up. Here, what is intended to solve the above-mentioned problems is an assembly box that can be easily disassembled according to the present invention.
