Claims Analysis

Total Claims: 15
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.
Claim 3
Dependent Claim 18 words
A method according to claim 1, in which the edge part is a flange connected to the lid.
Claim 4
Dependent Claim 25 words
A method according to claim 2, in which the edge part is sandwiched between the two other parts, which are in face to face relationship.
Claim 5
Dependent Claim 30 words
A method according to claim 3, in whiCh the said two other parts are formed by portions of material folded down the inner face of the front and up again.
Claim 6
Dependent Claim 21 words
A method according to claim 4, in which the said two parts are glued together along a line below their midheight.
Claim 7
Dependent Claim 63 words
A method according to claim 2, in which the edge part is flat when unstressed and the said two other parts are flat and in a common plane when unstressed and the edge part is flexed so as to press against the outer face of a first of the other parts and against the inner face of the second of the other parts.
Claim 8
Dependent Claim 53 words
A method according to claim 6, in which the said two other parts are an upper and a lower part of the front, and the flange lies outside the upper part and inside the lower part, and has a tongue engaged in a slot at the junction of the front and the bottom.
Claim 9
Dependent Claim 16 words
A method according to claim 1, in which the parts closing the ends are glued together.
Claim 10
Dependent Claim 41 words
A method according to claim 4, including securing the inner of the said two parts to the front by gluing together flaps extending from the front at the ends and respective flaps extending from the inner of the said two parts.
Claim 11
Dependent Claim 26 words
A method according to claim 2, including interlocking two oppositely facing notches in the said edge part with respective notches on the said two other parts.
Claim 12
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 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.
Claim 15
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.
