Claims

[Claims for Utility Model Registration] (1) A rear wall portion, a left side wall portion composed of a rectangular tube shape,
A box bottom structure in which a front wall and a right side wall are connected through a fold, and at the lower edge of each wall, a pair of inner and outer bottoms forming the bottom are connected through a fold. In each of the pair of inner bottom portions connected to the lower edges of the left and right side walls, there is a diagonal slit in the direction of both ends of the fold, a straight slit that continues parallel to the fold, and a hook at both ends of the slit. A locking slit portion consisting of a main insertion receiving piece and a secondary insertion receiving piece is formed from a shaped slit, and a pair of outer bottom portions connected to the lower edges of the front and rear walls are It has an inverted trapezoidal shape with a narrow tip and sloped side edges on both sides, and the sloped side edges include an arcuate side edge that is inserted into the diagonal slit of the locking slit portion, and an arcuate side edge that engages with the straight slit. A straight edge to be stopped and a beak-like protrusion having a pointed end at the intersection of the edges are provided opposite each other, and the beak-like protrusion is formed by pressing the outer bottom surface that can be bent inward against the inner bottom surface. A bottom lock structure for an assembly box, characterized in that a protrusion is inserted into and locked into the locking slit. (2) The bottom lock structure of an assembly box according to claim 1, wherein reinforcing pieces are provided protruding from the outer bottom surface portion to cross-engage with each other at the leading edges.
