Abstract
This disclosure relates to an easy opening package including a carton body having a bottom panel and four upstanding side panels terminating in free terminal upper edges and the cover including a top panel and four depending side panels, a tear strip formed in one cover side panel dividing the latter into upper and lower panel portions, and a carton body side wall underlying the one cover side wall including a pair of spaced weakening lines whereby upon removal of the tear strip the one carton body side panel can be opened by rupturing along the weakening lines to gain access to a product adapted to be packaged within the package.

A package consisting solely of a cover, a carton body, and an edible product in said carton body, said carton body being defined by a bottom panel and four upstanding side panels generally normal thereto, a gusset panel between adjacent side panels of said carton body, said gusset panel being defined by a pair of panel portions overfolded into contiguous relationship to each other, adhesive means bonding said gusset panels and side panels to maintain a generally polygonal configuration to said four upstanding side panels as viewed in top plan, each of said side panels terminating in a free terminal edge, said cover including a top panel and four side panels joined thereto along associated fold lines, said cover being disposed upon said carton body with the fold lines thereof contiguous said free terminal edges, said cover and carton body side panels being directly bonded to each other, cooperative means between one of said carton body side panels and an overlying one of said cover side panels for rupturing both of the latter to provide an access opening for the removal of the edible product, said cooperative means including a narrow tear strip in said one cover side panel running generally the length thereof between end edges of said one cover panel, and said cooperative means further including a wide tear strip in said one carton body side panel running generally the height thereof whereby upon the removal of said narrow tear strip said one cover side panel is ruptured to permit access to and rupture of said carton body side panel wide tear strip.
An easy opening package comprising a carton body and a cover, said carton body including a bottom panel and four upstanding side panels, one of said side panels being defined by a fold line joining the same to said bottom panel, a pair of spaced side edges, and a free terminal upper edge, said cover including a top panel and four depending side panels, said cover side panels being joined by fold lines to said top panel, at least one of said cover side panels being overfolded directly against one of said carton body side panels about a first fold line, a tear strip formed in said one cover side panel, said tear strip dividing said one cover side panel into upper and lower panel portions with said tear strip therebetween, means primarily bonding said lower panel portion to said one carton body side panel, and said one carton body side panel including a pair of spaced weakening lines between and inboard of said spaced side edges disposed between said fold line and said free terminal edge.
