Abstract

A blank for forming a carton of the end loading type for containing a plurality of beverage cans, the capacity of the carton can be increased to accommodate the insertion of ice-cubes into the carton for cooling the beverage cans contained therein, the blank for forming the carton, including a series of main panels including at least one top panel, one of the top panels having a tear strip and thereby being separable into two parts, the blank further including end extension panels, wherein upon constructing the blank into the set up carton, separating the top panel, by deploying the tear strip, allows each end extension panel and each of the separated parts of the top panel to be raised above the tops of the beverage cans to increase the capacity of the carton to accommodate the insertion of ice cubes.

Claims

1. A carton of the end loading type for containing a plurality of similar articles and:

being structured such that the capacity of the carton can be increased when opened, the carton comprising a series of main panels hinged one to the next, including a bottom panel, first and second side panels and at least one top panel, said at least one top panel having a tear strip and thereby being separable into two parts, said at least one top panel being hinged at each end thereof to at least a portion of an end extension panel, the carton further comprising a top end closure panel hinged to each end extension panel and bottom and side end closure panels hinged to opposing ends of the bottom and side panels, characterized in that the end extension panels are disposed beneath said at least one top panel and in that separating said at least one top panel, by deploying the tear strip, allows each end extension panel and each of the separated parts of said at least one top panel to be raised into substantially the same plane as respective adjacent side and end walls, thereby increasing the capacity of the open carton.

2. A carton according to claim 1 wherein said at least one top panel comprises two top panels, the two top panels being hinged to the side panels respectively.

3. A carton according to claim 1 wherein said at least one top panel is hinged to a portion of an end extension panel and wherein each portion is secured to a second portion to form two composite end extension panels.

4. A carton according to claim 3 wherein each composite end extension panel is hinged to a top end closure panel.

5. A carton according to claim 4 wherein each top end closure panel is formed from two portions.

6. A carton according to claim 1 further comprising a handle aperture formed in each end extension panel for carrying the opened carton.

7. A carton according to claim 1 wherein each bottom end closure panel comprises a handle aperture for carrying the carton.

8. A carton according to claim 1 formed from a sheet material, one side of which being coated with a water resilient coating.

9. A blank for forming a carton of the end loading type, the carton for containing a plurality of similar articles and being structured such that the capacity of the carton can be increased when opened, the blank comprising a series of main panels hinged one to the next, including a bottom panel, first and second side panels and at least one top panel, said at least one top panel having a tear strip and thereby being separable into two parts, said at least one top panel being hinged at each end thereof to at least a portion of an end extension panel, the blank further comprising a top end closure panel hinged to each end extension panel and bottom and side end closure panels hinged to opposing ends of the bottom and side panels, characterized in that the end extension panels are disposed beneath said at least one top panel when the carton is set up and in that separating said at least one top panel, by deploying the tear strip, allows each end extension panel and each of the separated parts of said at least one top panel to be raised into substantially the same plane as respective adjacent side and end walls, thereby increasing the capacity of the open carton.

10. A blank according to claim 9 wherein said at least one top panel comprises two top panels, said two top panels being hinged to the side panels respectively.

11. A blank according to claim 10 wherein each end of each of said top panels is hinged to a portion of an end extension panel wherein upon constructing the blank into a set up carton each portion is secured to a second portion to form two composite end extension panels.

12. A blank according to claim 11 wherein each portion of the end extension panel is hinged to a portion of a top end closure panel wherein upon constructing the blank into a set up carton each portion of the top end closure panels is secured to a second of said portions to form two composite top end closure panels.

13. A blank according to claim 9 further comprising a handle aperture in each end extension panel for carrying the opened carton.

14. A blank according to claim 9 wherein each bottom end closure panel comprises a handle aperture for carrying a set up carton.

15. A blank according to claim 9 wherein one side of the blank is coated with a water resilient coating.
