Abstract

Aspects of the disclosure relate to a carton for packaging one or more articles, a blank for forming the carton and a method of packaging articles. The carton comprises a plurality of primary panels including a pair of bottom lap panels ( 12, 20 ) secured together to allow the primary panels to form walls of a tubular structure. An upper end closure structure partially closes an end of the tubular structure. The upper end closure structure comprises a lower edge that defines at least in part a window for exposing to view contents (B) of the carton. The upper end closure structure comprises a top end closure flap ( 30 a, 30 b, 30 c, 30 d ) having a handle opening defined therein and a pair of side end closure flaps ( 26 a, 26 b, 34 a, 34 b ). The side end closure flaps comprise an outer surface and an inner surface opposing the outer surface. The outer surface of each of the side end closure flaps comprises a glue area (G 1 , G 2 ).

First claim

The invention claimed is:

1. A carton comprising:
a plurality of primary panels including a pair of bottom lap panels secured together to allow the primary panels to form walls of a tubular structure, an upper end closure structure partially closing an end of the tubular structure, the upper end closure structure having a lower edge that defines at least in part a window that provides for certain contents of the carton to be displayed at the end of the tubular structure, the upper end closure structure comprising a top end closure flap comprising a handle opening defined therein and a pair of side end closure flaps, the side end closure flaps comprising an outer surface and an inner surface opposing the outer surface, the outer surface of each of the side end closure flaps comprising a glue area, wherein each glue area is adhesively secured to an inside surface of the top end closure flap, and wherein each of the glue areas is disposed below the handle opening.

2. A carton according to claim 1 wherein each side end closure flap comprises a limb portion extending from a main body, wherein each of the glue areas is provided by at least a part of the limb portion.

3. A carton according to claim 1 wherein each of the side end closure flaps is coupled to the top end closure flap.

4. A carton according to claim 3 wherein the upper end closure structure comprises a pair of web panels, each of the web panels connecting a respective one of the pair of side end closure flaps to the top end closure flap.

5. A carton according to claim 1 wherein the carton comprises a display window defined at least in a first side wall for display of at least one article.

6. A carton according to claim 5 , wherein the display window is defined at least in part by a displaceable flap hingedly connected to the first side wall.

7. A carton according to claim 1 wherein a top wall of the tubular structure is shorter in a longitudinal direction than a base wall of the tubular structure.

8. A carton according to claim 1 wherein a top wall of the tubular structure is shorter in a transverse direction than a base wall of the tubular structure.

9. A blank comprising:
a plurality of primary panels for forming walls of a tubular structure, the plurality of primary panels including a pair of bottom lap panels securable together, a plurality of end closure flaps for forming an upper end closure structure for partially closing an end of the tubular structure, at least one of the plurality of end closure flaps providing, in a setup carton formed from the blank, a lower edge that defines at least in part a window that provides for certain contents of the carton to be displayed at the end of the tubular structure, the upper end closure structure comprising a top end closure flap comprising a handle opening defined therein and a pair of side end closure flaps, the side end closure flaps comprising an outer surface and an inner surface opposing the outer surface, the outer surface of each of the side end closure flaps comprising a glue area, wherein each glue area is adhesively securable to an inside surface of the top end closure flap, and wherein each of the glue areas is configured to be disposed below the handle opening in the setup carton.

10. A blank according to claim 9 , wherein each side end closure flap comprises a limb portion extending from a main body, wherein each of the glue areas is provided by at least a part of the limb portion.

11. A blank according to claim 9 , wherein each of the side end closure flaps is coupled to the top end closure flap.

12. A blank according to claim 9 , wherein the upper end closure structure comprises a pair of web panels, each of the web panels connecting a respective one of the pair of side end closure flaps to the top end closure flap.

13. A blank according to claim 9 , further comprising a display window defined at least in a first side wall of the tubular structure for display of at least one article.

14. A blank according to claim 13 , wherein the display window is defined at least in part by a displaceable flap hingedly connected to the first side wall.

15. A blank according to claim 9 , wherein a top wall of the tubular structure is shorter in a longitudinal direction than a base wall of the tubular structure.

16. A blank according to claim 9 , wherein a top wall of the tubular structure is shorter in a transverse direction than a base wall of the tubular structure.

17. A package comprising:
a group of articles and a carton disposed along a part of the exterior of the group of articles, the carton comprising:
an upper end closure structure partially closing an end of the carton, the upper end closure structure having a lower edge that defines at least in part a window through which at least one of the articles of the group is exposed to view, wherein the upper end closure structure comprises:
a top end closure flap having a handle opening, and
a pair of side end closure flaps, the side end closure flaps each comprising an outer surface, and an inner surface opposing the outer surface, the outer surface of each of the side end closure flaps comprising a glue area, wherein each glue area is adhesively secured to an inside surface of the top end closure flap, wherein each of the glue areas is disposed below the handle opening, and wherein at least a portion of the inner surface of each side end closure flap disposed below the handle opening is in substantial face-contacting arrangement with the at least one of the articles of the group;

a plurality of primary panels including a pair of bottom lap panels secured together to allow the primary panels to form walls of a tubular structure.
