<p><P>PROBLEM TO BE SOLVED: To provide a packaging box, which is easy to open and to which an adhesive can be applied in a wide range without sticking the adhesive to a housed matter. <P>SOLUTION: The adhesive can be applied in the wide range without sticking the adhesive (a hot melt adhesive) to the housed matter and satisfactory adhesion strength can be obtained, by forming a pair of inner flaps 16 and 18 in dimensions such that tip edges can be confronted with each other when bent inside. In addition, notched parts 23 are provided in a positions on the inner flaps 16 and 18 superposed on easy breakthrough parts 21 provided in an outer flap 15 upon sealing, and cut lines 25, extended by a prescribed length along an extended direction of front end edges with the notched parts 23 as the starting points, are provided at a position separated by prescribed distance from the front end edges of the inner flaps 16 and 18. Thereby, peeling of the outer flaps 15 and 17 upon opening can be easily attained without being inhibited by the inner flaps 16 and 18. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
