Abstract
Abstract For preventing damage to the tops and bottoms of end loading stacked can cartons, a reinforcing panel is affixed to the inside surface of the top or bottom walls of the carton or to both such walls so as to prevent coincidental can chimes on the upper ends of cans in a lower carton from damaging the top wall of its associated carton and the bottom wall of a carton stacked thereabove and without which the lower ends of the cans of the upper carton may cooperate with the chimes of the cans in the lower cartons to effect substantial damage to the top of the lower carton and to the bottom of the upper carton. For facilitating entry of the cans into an end loading carton and for preventing damaging engagement between the cans and the reinforcing panels, an inwardly extending embossment may be formed in the carton wall adjacent the end edge of the reinforcement panel and if desired the end edge of the reinforcement panel adjacent the end of the carton through which the cans are loaded may be bevelled or may be otherwise configured so as to prevent damage to the carton due to loading of the cans.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
190 words
An end loading can carton comprising a normally horizontal bottom wall, a pair of side walls foldably joined respectively to opposite side edges of said bottom wall, a normally horizontal top wall foldably joined along the side edges thereof to the upper edges of said side walls respectively to form a sleeve with said side walls and the axes of the packaged cans in normal relation to said bottom and said top walls, an end flap foldably joined to each end of said bottom, top and side walls along a fold line which defines the associated end edge of the associated wall, and a reinforcing panel secured in flat face contacting relation to the inner surface of one of said normally horizontal walls for directly engaging the adjacent ends of the packaged cans, the fold line adjoining the end flap at one end of said one normally horizontal wall being inwardly embossed for engaging the adjacent ends of cans to be packaged during loading of the cans into the carton thereby to minimize possible disruptive engagement of the adjacent can ends with the adjacent end edge of said reinforcing panel.
Claim 2
Dependent Claim
190 words
An end loading can carton comprising a normally horizontal bottom wall, a pair of side walls foldably joined respectively to opposite side edges of said bottom wall, a normally horizontal top wall foldably joined along the side edges thereof to the upper edges of said side walls respectively to form a sleeve with said side walls and the axes of the packaged cans in normal relation to said bottom and said top walls, an end flap foldably joined to each end of said bottom, top and side walls along a fold line which defines the associated end edge of the associated wall, and a reinforcing panel secured in flat face contacting relation to the inner surface of one of said normally horizontal walls for directly engaging the adjacent ends of the packaged cans, the fold line adjoining the end flap at one end of said one normally horizontal wall being inwardly embossed for engaging the adjacent ends of cans to be packaged during loading of the cans into the carton thereby to minimize possible disruptive engagement of the adjacent can ends with the adjacent end edge of said reinforcing panel.
Claim 3
Dependent Claim
55 words
An end loading can carton according to claim 1 wherein said adjacent end edge of said reinforcing panel is bevelled inwardly and away from the adjacent end of the carton to facilitate entry of the cans into the carton by avoiding disruptive collision of the cans with said adjacent end edge of said reinforcing panel.
Claim 4
Dependent Claim
64 words
An end loading can carton according to claim 1 wherein the inner surface of said one of said normally horizontal walls is coated with a water resistant material to cause water condensate on the cans to be absorbed by said reinforcing panel and to prevent water penetration of said one of said normally horizontal walls and possible blemish of the outer printed surface thereof.
Claim 5
Dependent Claim
52 words
An end loading can carton according to claim 1 wherein a reinforcing panel is secured in flat face contacting relation with the inner surface of said top and said bottom walls and wherein the fold line adjoining the end flap at one end of said top and bottom wall is inwardly embossed.
Claim 6
Dependent Claim
40 words
An end loading can carton according to claim 1 wherein said adjacent end edge of said reinforcing panel is spaced inwardly from the adjacent end of the carton by a distance substantially less than one-half the diameter of a can.
Claim 7
Dependent Claim
50 words
An end loading can carton according to claim 1 wherein said reinforcing panel is slightly smaller in area than its associated normally horizontal panel and wherein its edges are spaced from the corresponding edges of its associated normally horizontal panel by a distance less than one-half of a can diameter.
