Abstract

PROBLEM TO BE SOLVED: To readily open a packaging box sealed by insertion. SOLUTION: A cover plate 7 extends from the top edge of a rear wall 3 and a cover receiving plate 8 from the top edge of a front wall 1, a sector pressing piece 12 is formed by perforating the front end portion of the cover plate 7 and further an inserting piece 13 is connected to its front edge, projecting pieces 15 are provided on both sides of a through hole 14 cut out of the base end of the cover receiving plate 8. The cover plate 7 is overlapped on the cover receiving plate 8, and the inserting piece 13 is inserted between the projecting pieces 15 and the front wall 1 to lock the cover plate 7 by preventing the inserting piece 13 from its dislocation. On the contrary, pressing the pressing piece 12 releases the lock of the cover plate 7 due to the dislocation of the inserting piece 13 from the through hole 14 while folding the projecting pieces 15.
