Abstract
Abstract A blank, and a reclosable carton made from the blank, include a receptacle portion and a cover portion which may be pivoted to overlap and close the otherwise open top of the receptacle portion. The cover portion comprises a pair of opposed side cover panels, each in turn comprising a first panel portion connected to and depending from a top cover panel, and a second locking panel portion connected to the first panel portion by a line of severance. Each of the second locking panel portions overlays and is adhered to an associated side panel of the receptacle portion, the cover portion being adhered to the receptacle portion exclusively by the second locking panel portions. The carton thus formed uses less paperboard and less glue than the known reclosable cartons and is also easier to open initially.
