ABSTRACT:
A carton having structure for locking the cover thereof in place after the seal has been broken, carton blanks for the production thereof, and an end closure for such a carton are disclosed. The lock structure comprises two elements, the first a centrally-located lock flap articulated along its one edge to the upper edge of the carton front face panel and separated by a cut from the second lock flap, which is secured on the inner surface of the cover front panel, said second lock flap comprising two surrounding webs which are, in the carton blank and in the originally sealed carton, attached along lines of severance to the upper edge of the carton front face panel and which become detached along said severance lines during opening of the originally sealed carton. The second lock flap peripherally or circumferentially substantially abuts the free edges of the first lock flap along all of the free edges thereof, thereby enabling rapid and positive relocking of the carton upon reclosure after the original package has been opened. The carton is characterized by numerous advantages over prior art constructions due to the novel lock structure, in which the respective lock flaps or elements are always in substantially abutting mutual engagement along all of the free edges of the lock flap appended to the upper edge of the carton front face panel, and does not depend upon mutual engagement along ruptured perforation lines or precise squaring of the carton during its erection for positive effectiveness of the lock structure, and moreover is characterized by economic advantage in that the lock structure minimizes the amount of paperboard which must be employed in constructing the carton including the lock structure thereof from an integral blank.
