Claim 1
Independent Claim
225 words
A carton comprising a generally tubular body including a top panel joined to a pair of side panels by first and second longitudinal fold lines, a pair of end panels at one axial end of said body substantially closing the same, first and second ones of said end panels being joined to first and second ones of said side panels by respective first and second vertical fold lines, said end panels having free upper terminal ends, and means holding said ends disposed inboard of said body to maintain at least portions of said end panels normal to said side walls, said holding means including a central locking panel portion joined by a first transverse fold line to said top panel and a pair of locking panel portions outboard thereof, one outboard locking panel portion being joined between said top panel and each of said first and second side panels by a pair of angularly disposed fold lines, said central locking panel portion being folded downwardly about said first transverse fold line into overlying relationship to said terminal end panel ends, and said outboard locking panels being folded inwardly of said body in generally sIde-by-side relationship to adjacent ones of said side panels for maintaining said central locking panel portion in its overlying position whereby said end panels are precluded from moving outward of said body.
