Abstract
A paperboard carton, of improved end sealability, has two end flaps with debossed portions, a third end flap with an embossed portion, and a fourth, planar, end flap captured between the debossed and embossed flaps. The debossed end flaps comprise an opposed pair connected to the narrower side panels of the carton, while the embossed and planar flaps are connected to the relatively wider front and back panels respectively. Due to the effectiveness of the end closure, substantial flap overlap is no longer required for adequate sealing and it is possible to substantially reduce the length of the end flaps connected to the side panels and the back panel, as compared to those of a conventional carton of the same overall size.
