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 panels forming walls of a tubular structure including a top wall, a first side wall, a base wall, and a second side wall. An end closure structure at least partially closes an end of the tubular structure. The end closure structure includes: a top end closure flap having a handle opening forming a carrying handle; a side end closure flap coupled to one of the first and second side walls; and a web panel interconnecting the top end closure flap to the side end closure flap. The web panel is hingedly connected to the top end closure flap and is hingedly connected to the side end closure flap along a fold line.

First claim

The invention claimed is:

1. A carton for packaging one or more articles, the carton comprising a plurality of panels forming walls of a tubular structure including a top wall, a first side wall, a base wall, and a second side wall, and an end closure structure for at least partially closing an end of the tubular structure, the end closure structure comprising:
a top end closure flap having a handle opening forming a carrying handle;
a side end closure flap coupled to one of the first and second side walls; and
a web panel interconnecting the top end closure flap to the side end closure flap;
wherein the web panel is hingedly connected to the top end closure flap and is hingedly connected to the side end closure flap along a web-panel-to-side-end fold line, wherein the web panel is separated from the side end closure flap by a disconnection element extending from the web-panel-to-side-end fold line such that the disconnection element defines an upper edge of a handle reinforcing portion of the side end closure flap for reinforcing the carrying handle, wherein the upper edge of a handle reinforcing portion of the side end closure flap and the web-panel-to-side-end fold line define an angle therebetween, the angle being less than 180 degrees, and wherein the web-panel-to-side-end fold line either (i) is interrupted by a linearly aligned cut line or (ii) extends adjacent to a corner formed at least in part by the top end closure flap and the top wall.

2. A carton according to claim 1 wherein the disconnection element is formed from a feature selected from the group consisting of: a cutline, a severable line, a tear line, a slit, a slot, a notch and a cutout.

3. A carton according to claim 1 wherein the angle is an obtuse angle.

4. A carton according to claim 1 wherein the end closure structure comprises:
a second side end closure flap, the second side end closure flap is coupled to the other one of the first and second side walls;
a second web panel connects the top end closure flap to the second side end closure flap;
wherein the second web panel is hingedly connected to the top end closure flap and is hingedly connected the second side end closure flap along a further fold line, the second web panel is separated from the second side end closure flap by a second disconnection element extending from the further fold line such that the second disconnection element defines an upper edge of a handle reinforcing portion of the second side end closure flap for reinforcing the carrying handle, and wherein the upper edge of the handle reinforcing portion of the second side end closure flap and the further fold line define an angle therebetween, the angle may be less than 180 degrees.

5. A carton according to claim 4 wherein the handle reinforcing portion of the side end closure flap and the handle reinforcing portion of the second side end closure flap together extend along an engaging edge of the handle opening so as to reinforce the handle opening thereacross.

6. A carton according to claim 1 wherein the carton comprises a display window defined at least in the first side wall, formed without tearing by a user, for display of at least one article.

7. A carton according to claim 1 wherein a top opening is defined, at least in part, in the top wall, without tearing by a user, the top opening being configured to receive an upper portion of said at least one article and wherein a bottom opening is defined, at least in part, in the base wall, at least in partial vertical registry with a position of said at least one article, the bottom opening being configured to access said at least one article to raise and lower the elevation thereof such that the upper portion of said at least one article is movable upward and downward through the top opening.

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

9. A carton according to claim 1 wherein the top wall is shorter in a longitudinal direction than the base wall.

10. A carton according to claim 1 wherein the top wall is shorter in a transverse direction than the base wall.

11. A carton according to claim 1 wherein the disconnection element extends from a lower end of the web-panel-to-side-end fold line.

12. A carton according to claim 1 wherein the top end closure flap is hingedly connected to the top wall along a fold line, and wherein the web-panel-to-side-end fold line defines an acute angle with respect to the fold line between the top end closure flap and the top wall.

13. A blank for forming a carton, the blank comprising a plurality of panels for forming walls of a tubular structure, the plurality of panels including a top panel, a first side panel, a base panel, and a second side panel, the blank comprising panels for forming an end closure structure for at least partially closing an end of the tubular structure, the end closure structure comprising:
a top end closure flap having a handle opening for forming a carrying handle;
a side end closure flap coupled to one of the first and second side panels; and
a web panel interconnecting the top end closure flap to the side end closure flap;
wherein the web panel is hingedly connected to the top end closure flap and is hingedly connected to the side end closure flap along a web-panel-to-side-end fold line, wherein the web panel is separated from the side end closure flap by a disconnection element extending from the web-panel-to-side-end fold line such that the disconnection element defines an upper edge of a handle reinforcing portion of the side end closure flap for reinforcing the carrying handle, and wherein the upper edge of a handle reinforcing portion of the side end closure flap and the web-panel-to-side-end fold line define an angle therebetween, the angle being less than 180 degrees.

14. A blank according to claim 13 wherein the disconnection element extends from a lower end of the web-panel-to-side-end fold line.

15. A blank according to claim 13 wherein the top end closure flap is hingedly connected to the top panel along a fold line, and wherein the web-panel-to-side-end fold line defines an obtuse angle with respect to the fold line between the top end closure flap and the top panel.

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

17. A blank according to claim 16 , wherein the display window aperture is defined at least in part by a displaceable flap hingedly connected to the first side wall.

18. A blank according to claim 13 , wherein the web-panel-to-side-end fold line either (i) is interrupted by a linearly aligned cut line or (ii) extends adjacent to a corner formed at least in part by the top end closure flap and the top wall.

19. A carton for packaging one or more articles, the carton comprising a plurality of panels forming walls of a tubular structure including a top wall, a first side wall, a base wall, and a second side wall, and an end closure structure for at least partially closing an end of the tubular structure, the end closure structure comprising:
a top end closure flap having a handle opening forming a carrying handle;
a side end closure flap coupled to one of the first and second side walls; and
a web panel interconnecting the top end closure flap to the side end closure flap;
wherein the web panel is hingedly connected to the top end closure flap and is hingedly connected to the side end closure flap a
