Abstract
Abstract An economical mechanically strong bottle carrier of the wrap around type having top, bottom and side walls interconnected to form a tubular open ended structure is provided with bottle engaging and carrier reinforcing flaps which are associated with certain bottle heel receiving apertures at the carrier corners are arranged so as effectively to prevent dislodgment of the bottles from the open ended tubular structure and which in addition constiute significant reinforcement for the corners of the carrier so that the carrier formed of light weight paperboard is of sufficient mechanical strength whereby rupture of the carrier is prevented and secure retention of bottles is effected.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
186 words
A bottle carrier of the wrap around type having top, bottom and side walls interconnected to form a tubular open ended structure wherein a sloping heel panel is interconnected with each side wall along a fold line and with an associated bottom lap panel along a fold line and wherein bottle heel receiving apertures are formed in each sloping heel panel which extend into the associated side wall and lap panel and wherein the improvement comprises combination bottle engaging and carrier reinforcing flaps foldably joined respectively along the outer edges of the bottle heel receiving apertures which are disposed immediately adjacent the open ends of the carrier, each bottle engaging and carrier reinforcing flap extending across the associated sloping heel panel and into the associated side wall and lap panel and having a fold line formed therein one end of which coincides with the fold line between the associated sloping heel panel and the associated lap panel and which is angularly disposed to said fold line and which is disposed in a plane which is substantially parallel with the inner surface of the associated lap panel.
Claim 2
Dependent Claim
186 words
A bottle carrier of the wrap around type having top, bottom and side walls interconnected to form a tubular open ended structure wherein a sloping heel panel is interconnected with each side wall along a fold line and with an associated bottom lap panel along a fold line and wherein bottle heel receiving apertures are formed in each sloping heel panel which extend into the associated side wall and lap panel and wherein the improvement comprises combination bottle engaging and carrier reinforcing flaps foldably joined respectively along the outer edges of the bottle heel receiving apertures which are disposed immediately adjacent the open ends of the carrier, each bottle engaging and carrier reinforcing flap extending across the associated sloping heel panel and into the associated side wall and lap panel and having a fold line formed therein one end of which coincides with the fold line between the associated sloping heel panel and the associated lap panel and which is angularly disposed to said fold line and which is disposed in a plane which is substantially parallel with the inner surface of the associated lap panel.
Claim 3
Dependent Claim
49 words
A bottle carrier according to claim 1 wherein a second fold line is formed in each of said bottle engaging and carrier reinforcing flaps and wherein an end of each of said second fold lines coincides with the fold line between the associated side wall and sloping heel panel.
Claim 4
Dependent Claim
39 words
A bottle carrier according to claim 1 wherein a second bottle engaging carrier reinforcing flap is foldably joined along the inner edge of each bottle heel receiving aperture which is disposed immediately adjacent the open ends of the carrier.
Claim 5
Dependent Claim
43 words
A bottle carrier according to claim 3 wherein a fold line is formed in each of said second bottle engaging carrier reinforcing flaps one end of which coincides with the fold line between the associated sloping heel panel and the associated lap panel.
Claim 6
Dependent Claim
38 words
A bottle carrier according to claim 1 wherein each bottle engaging and carrier reinforcing flap is foldably joined to the outer edge of the associated bottle heel receiving aperture along a fold line comprising two angularly related parts.
Claim 7
Dependent Claim
28 words
A bottle carrier according to claim 5 wherein said angularly related parts intersect at the fold line between the associated sloping heel panel and the associated lap panel.
Claim 8
Dependent Claim
201 words
A bottle carrier of the wrap around type having top, bottom and side walls interconnected to form a tubular open ended structure wherein a sloping heel panel is interconnected with each side wall along a fold line and with an associated bottom lap panel along a fold line and wherein bottle heel receiving apertures are formed in each sloping heel panel which extend into the associated side wall and lap panel and wherein the improvement comprises combination bottle engaging and carrier reinforcing flaps foldably joned respectively along the outer edges of the bottle heel receiving apertures which are disposed immediately adjacent the open ends of the carrier, each bottle engaging and carrier reinforcing flap having a fold line formed therein one end of which coincides with the fold line between the associated sloping heel panel and the associated lap panel and which is disposed in a plane which is substantially parallel with the inner surface of the associated lap panel, and a second fold line formed in each of said bottle engaging and carrier reinforcing flaps and wherein an end of each of said second fold lines coincides with the fold line between the associated side wall and sloping heel panel.
Claim 9
Dependent Claim
201 words
A bottle carrier of the wrap around type having top, bottom and side walls interconnected to form a tubular open ended structure wherein a sloping heel panel is interconnected with each side wall along a fold line and with an associated bottom lap panel along a fold line and wherein bottle heel receiving apertures are formed in each sloping heel panel which extend into the associated side wall and lap panel and wherein the improvement comprises combination bottle engaging and carrier reinforcing flaps foldably joned respectively along the outer edges of the bottle heel receiving apertures which are disposed immediately adjacent the open ends of the carrier, each bottle engaging and carrier reinforcing flap having a fold line formed therein one end of which coincides with the fold line between the associated sloping heel panel and the associated lap panel and which is disposed in a plane which is substantially parallel with the inner surface of the associated lap panel, and a second fold line formed in each of said bottle engaging and carrier reinforcing flaps and wherein an end of each of said second fold lines coincides with the fold line between the associated side wall and sloping heel panel.
Claim 10
Dependent Claim
