PROBLEM TO BE SOLVED: To obtain a paper box capable of keeping a lid plate in an upright attitude when necessary and easily handled by preventing a lid plate from causing hindrance to taking out of granular sweets or the like. SOLUTION: As a lid plate body 10 is pulled upward, a closing plate 15 located at a take-out opening 16 rotates and the downward movable part 18 of the closing plate 15 turns toward the inside of the box. The downward movable part 18 makes slide contact with and moves to the projection 24 of the take-out opening 16. The upright attitude of the lid plate body 10 is maintained by the locking of the downward movable part 18 and the projection 24 due to unfolding. COPYRIGHT: (C)2009,JPO&INPIT
