Claim 1
Independent Claim
115 words
A method of making a carton of a single blank of sheet material comprising the steps of folding the blank into an open ended tube comprising a front, bottom, rear, and top of the carton, forming a joint in the circumference of the tube by placing an edge part of the blank in a gripped situation between two other parts of the blank, and thereafter closing the ends of the carton by further parts of the blank so that the carton is able to be opened by withdrawing the said edge part from between the two other parts and lifting the entire top as part of a lid hinged to the remainder of the carton.
Claim 2
Independent Claim
115 words
A method of making a carton of a single blank of sheet material comprising the steps of folding the blank into an open ended tube comprising a front, bottom, rear, and top of the carton, forming a joint in the circumference of the tube by placing an edge part of the blank in a gripped situation between two other parts of the blank, and thereafter closing the ends of the carton by further parts of the blank so that the carton is able to be opened by withdrawing the said edge part from between the two other parts and lifting the entire top as part of a lid hinged to the remainder of the carton.

A carton comprising a single blank of sheet material, folded and joined into a tube comprising a front, bottom, rear and top of the carton, said blank including further parts for closing the ends of the carton, the joint in the circumference of the tube being formed by a flange connected to the lid, sandwiched between inner and outer portions of the material folded down the inner face of the front and up again, the front having flaps extending therefrom at the ends, and the inner of the said portions having further flaps extending therefrom and glued to the respective flaps of the front.
Claim 13
Dependent Claim
104 words
A carton comprising a single blank of sheet material, folded and joined into a tube comprising a front, bottom, rear and top of the carton, said blank including further parts for closing the ends of the carton, the joint in the circumference of the tube being formed by a flange connected to the lid, sandwiched between inner and outer portions of the material folded down the inner face of the front and up again, the front having flaps extending therefrom at the ends, and the inner of the said portions having further flaps extending therefrom and glued to the respective flaps of the front.
Claim 14
Dependent Claim
106 words
A partly-prepared carton comprising a single blank of sheet material, formed into a flattened tube comprising a front, bottom, rear and top for the carton, said blank including further parts for closing the ends of the carton after erection of the tube, a joint in the circumference of the flattened tube being constituted by an edge part of the blank gripped between two other parts of the blank so that the carton is able to be opened by withdrawing the said edge part from between the two other parts and lifting the entire top as part of a lid hinged to the remainder of the carton.
