Claim 1
Independent Claim
191 words
A carton for packaging articles and formed from a unitary blank comprises a top wall, a pair of side walls and a composite bottom wall foldably joined along their side edges to form a tubular structure and is provided with an end panel foldably joined to an end edge of said top wall at one end of the carton and folded inwardly toward the other end of the carton and into flat face contacting relation with the inner surface of the top wall, said end panel having an inner edge remote from said end edge of said top wall and having an aperture which is in coincidence with a corresponding aperture in said top wall for receiving a carton suspending hanger, a pair of end closing doors foldably joined respectively to the end edges of said side walls at said one end of the carton and arranged to expose said apertures when closed, and a web panel disposed in flat face contacting relation to said end panel and foldably joined to each end edge of said end panel and to the adjacent end edge of each of said end closing doors.
Claim 2
Dependent Claim
191 words
A carton for packaging articles and formed from a unitary blank comprises a top wall, a pair of side walls and a composite bottom wall foldably joined along their side edges to form a tubular structure and is provided with an end panel foldably joined to an end edge of said top wall at one end of the carton and folded inwardly toward the other end of the carton and into flat face contacting relation with the inner surface of the top wall, said end panel having an inner edge remote from said end edge of said top wall and having an aperture which is in coincidence with a corresponding aperture in said top wall for receiving a carton suspending hanger, a pair of end closing doors foldably joined respectively to the end edges of said side walls at said one end of the carton and arranged to expose said apertures when closed, and a web panel disposed in flat face contacting relation to said end panel and foldably joined to each end edge of said end panel and to the adjacent end edge of each of said end closing doors.
Claim 3
Dependent Claim
49 words
A carton according to claim 1 wherein folding said end panel into flat face contacting relation with said top wall and manipulating the blank while disposed in overlying relation to the articles by folding said side walls downwardly causes said end closing doors to swing into their closed positions.
Claim 4
Dependent Claim
37 words
A carton according to claim 1 wherein the upper ends of the articles are flanged and wherein the inner edge of said end panel is disposed below and in engagement with the flange of an adjacent article.
Claim 5
Dependent Claim
19 words
A carton according to claim 1 wherein article retaining means is disposed at the other end of the carton.
Claim 6
Dependent Claim
228 words
A carton for packaging articles and formed from a unitary blank comprises a top wall, a pair of side walls and a composite bottom wall foldably joined along their side edges to form a tubular structure, said carton comprising an end panel foldably joined to an end edge of said top wall at one end of the carton and folded inwardly into flat face contacting relation with the inner surface of the top wall, said end panel having an aperture which is in coincidence with a corresponding aperture in said top wall for receiving a carton suspending hanger, a pair of end closing doors foldably joined respectively to the end edges of said side walls at said one end of the carton, and a web panel foldably joined to each end edge of said end panel and to the adjacent one of said end closing doors so that folding said end panel into face contacting relation with said top wall swings said end closing doors partially toward closed positions while said side walls are disposed in substantially the same plane as said top wall and folding said side walls out of the plane of said top wall and downwardly to their final positions swings said end closing doors into their final end closing positions and swings said web panels into flat face contacting relation with said end panel.
