Abstract
Abstract A parallelepiped box (400) containing a roll of tear-off strip material and provided with a device for tearing off a portion of said strip is formed from a punched element (310). The box comprises one (128) or two (128 and 158) toothings which are formed in the cardboard of the punched element and when the box has been assembled correspond with that (28) of the long corners of the box which is opposite the long corner (24) about which the box lid rotates once the box has been opened. The toothings can be non-continuous, in which case the relative untoothed portions of one toothing can correspond with the toothed portions of the other. A strip of the cardboard punched element (310) comprising a relative toothing (128, 158) can be treated with a substance able to harden the cardboard.

Claim 1
Independent Claim
370 words
A parallelepiped box (400) containing a roll of tear-off strip material and provided with a device for tearing off a portion of said strip, said box being assembled from a punched sheet element (310) comprising: four adjacent main portions (14, 16, 18, 20) formed from substantially equal elongated rectangles which are parallel to each other and separated by creasing lines (24, 26, 28) along their longer sides; a secondary portion (12) of shape and dimensions substantially equal to those of said main portions and adjacent to one (14) of the two most outer main portions, with which it has in common one of its longer sides, along which there is provided a creasing line (22); and a pair of opposing flaps (32, 34, 36, 38), one at each end, which are rotatable about a creasing line provided along the relative short side of each main portion (14, 16, 18, 20) and secondary portion (12); the main portions and secondary portion forming the outer lateral surface of the parallelepiped box (400), and said flaps (32, 34 46, 48) forming the two bases of said box, when the box has been assembled the secondary portion (12) being superposed on that main portion (20) which has one side free, the box being openable along said secondary portion (12) to define a lid formed substantially from the main portion (14) adjacent to the secondary portion, said lid being rotatable about that long side (24) of the lid main portion (14) more distant from the secondary portion, there being provided a toothing (128), formed by cutting through the punched element (310), along the creasing line (128) which forms that (28) of the box corners lying opposite the long corner about which the box lid can rotate; characterised in that all or part of that edge strip (51, 55) of said secondary portion (12) of the punched element on the side comprising said toothing remains fixed to the underlying main portion (20) when the box has been assembled, even after the box has been opened, and that the points of the teeth of the toothing (128) lie in the plane containing the outer surface of said edge strip (51, 55) or project just beyond said plane.
Claim 2
Dependent Claim
370 words
A parallelepiped box (400) containing a roll of tear-off strip material and provided with a device for tearing off a portion of said strip, said box being assembled from a punched sheet element (310) comprising: four adjacent main portions (14, 16, 18, 20) formed from substantially equal elongated rectangles which are parallel to each other and separated by creasing lines (24, 26, 28) along their longer sides; a secondary portion (12) of shape and dimensions substantially equal to those of said main portions and adjacent to one (14) of the two most outer main portions, with which it has in common one of its longer sides, along which there is provided a creasing line (22); and a pair of opposing flaps (32, 34, 36, 38), one at each end, which are rotatable about a creasing line provided along the relative short side of each main portion (14, 16, 18, 20) and secondary portion (12); the main portions and secondary portion forming the outer lateral surface of the parallelepiped box (400), and said flaps (32, 34 46, 48) forming the two bases of said box, when the box has been assembled the secondary portion (12) being superposed on that main portion (20) which has one side free, the box being openable along said secondary portion (12) to define a lid formed substantially from the main portion (14) adjacent to the secondary portion, said lid being rotatable about that long side (24) of the lid main portion (14) more distant from the secondary portion, there being provided a toothing (128), formed by cutting through the punched element (310), along the creasing line (128) which forms that (28) of the box corners lying opposite the long corner about which the box lid can rotate; characterised in that all or part of that edge strip (51, 55) of said secondary portion (12) of the punched element on the side comprising said toothing remains fixed to the underlying main portion (20) when the box has been assembled, even after the box has been opened, and that the points of the teeth of the toothing (128) lie in the plane containing the outer surface of said edge strip (51, 55) or project just beyond said plane.
