ABSTRACT:
An improved storage and/or shipping box is provided having specially designed top closure flaps allowing easy mechanical interlocking of the flaps without tearing or other structural damage thereto, while at the same time permitting the flaps to be folded together and taped shut to close and seal the box in the conventional fashion for shipping purposes. A pair of adjacent rectangular closure flaps are provided with respective cut and weakness lines so as to present shiftable flap elements thereon which can be easily manipulated to allow complete interlocking of the flaps for temporary closure purposes; when it is desired to use the box for shipping purposes, the rectangular flaps can be folded together in the normal fashion, and the box taped shut.
