Abstract
A tissue box comprising front and rear surfaces including horizontal fold lines; a left end surface including a horizontal fold line and a vertical perforation line; a right end surface including a horizontal fold line and a vertical perforation line; a top surface including a tissue pull-out-port; a bottom surface including a horizontal perforation line at the center of said bottom surface and vertical perforation lines at either end; lock keys form in said bottom surface so that said left end surface and right end surface can tuck in said lock keys; and said front surface, rear surface, left end surface, right end surface, top surface, and bottom surface all foldably connect to form a rectangular box. By its construction, said tissue box height can be reduced to prevent the termination of the cascade pulling mechanism when the remaining number of tissues in the box becomes half or less.
