Abstract
Abstract A carton for packaging a plurality of cylindrical articles includes top, bottom and side walls foldably joined to form an end loading tubular structure, as well as end closure flaps foldably joined to each end edge of the top and side walls together with a bottom end closure flap adjoined to each end edge of the bottom wall of the carton by an upwardly and outwardly inclined bevel strip disposed alongside inwardly and downwardly inclined beveled circular connecting structure forming the lower rim portion of the packaged items thereby to eliminate square corners at the ends of the bottom of the carton and a resulting tendency of the end walls of the carton to bow outwardly when stacked in tiers, one above the other.

A carton for packaging a plurality of articles each having a cylindrical side wall, an inwardly recessed top and a bottom which is secured to the bottom edge of the side wall by an inwardly and downwardly beveled circular connecting structure, said carton comprising top, bottom and side walls foldably adjoined to form an end loading tubular structure, end closure flaps foldably joined to each end edge of said top and side walls, and a bottom end closure flap adjoined to each end edge of said bottom wall by an upwardly and outwardly inclined bevel strip.
Claim 2
Dependent Claim
96 words
A carton for packaging a plurality of articles each having a cylindrical side wall, an inwardly recessed top and a bottom which is secured to the bottom edge of the side wall by an inwardly and downwardly beveled circular connecting structure, said carton comprising top, bottom and side walls foldably adjoined to form an end loading tubular structure, end closure flaps foldably joined to each end edge of said top and side walls, and a bottom end closure flap adjoined to each end edge of said bottom wall by an upwardly and outwardly inclined bevel strip.
Claim 3
Dependent Claim
22 words
A carton according to claim 1 wherein each of said bevel strips is approximately equal in width to said circular connecting structure.
Claim 4
Dependent Claim
45 words
A carton according to claim 1 wherein each of said bevel strips is foldably adjoined along an inner edge thereof to an end edge of said bottom wall and along an outer edge thereof to the bottom edge of the associated bottom end closure flap.
Claim 5
Dependent Claim
22 words
A carton according to claim 1 wherein each of said bevel strips is disposed at an obtuse angle to said bottom wall.
Claim 6
Dependent Claim
25 words
A carton according to claim 1 wherein each of said bevel strips is disposed at an obtuse angle to the associated bottom end closure flap.
Claim 7
Dependent Claim
84 words
A carton according to claim 1 wherein said end closure flaps which are foldably joined respectively to the ends of said top wall are disposed in flat face contacting overlapping relation with the end closure flaps which are foldably joined respectively to the ends of said side walls and wherein each of said bottom end closure flaps is bonded to the associated end closure flaps which are foldably joined to the ends of said top wall and to the ends of said side walls.
Claim 8
Dependent Claim
81 words
A carton according to claim 6 wherein the outer corners of the end flaps which are foldably joined to said top wall are cut away so that an application of adhesive to the inner surface of each of said bottom end flaps forms a bond with the associated end closure flaps which are foldably joined to the end edges of said top wall and to the associated end closure flaps which are foldably joined to the ends of said side walls.
Claim 9
Dependent Claim
102 words
A carton according to claim 1 wherein stacking of cartons arranged in tiers one above the other in coincidental relation is such that the bottoms of the cans in an upper tier are disposed within the inwardly recessed tops of the cans in the tier disposed immediately below the cans in the upper tier, so as to prevent outward bowing of said end closure flaps and of said bottom end closure flaps at both ends of the cartons in the upper tier of cartons due to the angular disposition of the bevel strips in the cartons in the upper tier of cartons.
