摘要

The box comprises a bottom (20) and a cover (30) both having a similar shape and comprising a flat wall (22,32) whose edge is extended by a cylindrical side wall (24,34). The cover side wall telescopically slides on the bottom side wall in order to open or close the box. The height of the bottom side wall corresponds to the height of the box. The height of the cover side wall is greater than 60% of the box height. When the box is closed the cover side wall is located outside the bottom side wall and the free edge of the cover side wall has a side rib projecting beyond the outer face of the bottom side wall when the box is closed.
