Packaging Box
First Claim
1. A packaging box which has a substantially rectangular-parallelepiped shape and is capable of spreading to flat, comprising:
- a cylindrical body, and a pair of lids which each are provided in a pair of openings of the cylindrical body;
wherein;
the pair of lids each have a tongue which extends from their heads, the tongue being disposed so that it is opened and closed on its connection portion as a crease to the body of the packaging box with respect to the body of the packaging box, and a lid gluing portion which is arranged in a specific area on the outer surface of each tongue;
the body of the packaging box has a pair of body gluing portions which are individually glued to each lid gluing portion, the body gluing portions being arranged in each specific area of both open-side ends where they are placed on top of and joined to each tongue, and at least one transverse split-open portion which guides a fracture from one opening to the other opening in a side face of the packaging box; and
both open-side ends have side-end split-open portions which guide a fracture so that the body gluing portions are separated from the body when the body gluing portions are kept glued to the lid gluing portions, the side-end split-open portions being arranged so as to surround the body gluing portions.

Abstract
A packaging box (10) includes a pair of lids (2, 3), and the pair of lids (2, 3) have tongues (2b, 3b) extending from their heads and lid gluing portions (2c, 3c) arranged in specific areas on the outer surfaces of these tongues (2b, 3b). A body (1) of the packaging box (10) has a pair of body gluing portions (1f, 1g) individually glued to the lid gluing portions (2c, 3c) and at least one transverse split-open portion (5) for guiding a fracture in a side face of the packaging box (10). Both open-side ends (1e) have side-end split-open portions (6, 7) arranged so as to surround the body gluing portions (1f, 1g). Thus, even if the tongues provided at the heads of the lids are glued to side plates, the packaging box can be easily and accurately split and spread.
