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.
