ABSTRACT:
A carton, typically of corrugated paperboard, is formed from a one-piece blank having major side wall bottom flaps and minor end wall bottom flaps arranged to be securely interlocked, for which purpose openings which comprise or include slits are provided preferably in the major side wall bottom flaps into which may be inserted tabs preferably on the corners of the minor end wall bottom flaps. The tabs are shaped so as to provide hooks which engage exposed edges of the slits to lock and prevent the tabs from being accidentally withdrawn after insertion, thus providing a carton with a locked bottom closure.
