Abstract

A carton for packaging articles includes top ( 14 A, 14 B) and bottom ( 18, 20 ) connected together by spaced side walls ( 12 A, 12 B, 12 C; 16 A, 16 B, 16 C) to form a tubular structure, and an end closure structure ( 22 ) at one end of the tubular structure. Each end closure structure includes first and second top flaps ( 32 a, 32 b ) connected to the top ( 14 A, 14 B) and interconnected to anchoring panels ( 24 a , 24 b ). The top flaps are not directly connected together but through the top of the carton.

First claim

The invention claimed is:

1. A carton for packaging a plurality of articles, comprising:
top and bottom connected together by spaced side walls to form a tubular structure;
an end closure structure for at least partially closing one of opposed ends of the tubular structure, the end closure structure comprising
a pair of first and second sections connected to the top at the one of the opposed ends of the tubular structure;
wherein the sections each comprises a top flap hingedly connected to the top, and the top flaps at the one of the opposed ends of the tubular structure are not directly connected to each other;
wherein the top comprises a first top panel and a second top panel, the first and second top panels being hingedly connected together by a medial fold line extending between the opposed ends of the tubular structure, wherein the first top panel and the second top panel are not coplanar with one another, wherein the first top panel is parallel to the bottom and wherein the second top panel is not parallel to the bottom.

2. The carton according to claim 1 wherein each of the top flaps is hingedly connected through at least one gusset panel to an anchoring panel positioned between an adjacent one of the side walls and an adjacent one of the articles.

3. The carton according to claim 2 , wherein the anchoring panel is adhesively attached to the adjacent side wall panel.

4. The carton according to claim 2 wherein the anchoring panel is frictionally retained at a position between the adjacent one of the side walls and the adjacent one of the articles.

5. The carton according to claim 2 wherein the at least one gusset panel is triangular in shape.

6. The carton according to claim 2 , wherein the at least one gusset panel comprises two gusset panels hingedly connected together.

7. The carton according to claim 1 , wherein the top flaps are separated by a gap.

8. The carton according to claim 7 , wherein the medial fold line extends from the gap across the top to the other end of the tubular structure.

9. The carton according to claim 7 , wherein the gap comprises one selected from the group consisting of a cut and a cutout.

10. The carton according to claim 1 , wherein the side walls form a first side wall and a second side wall, and the first side wall being taller than the second side wall.

11. A blank for forming a carton for packaging a plurality of articles, the blank comprising:
a plurality of panels for forming a tubular structure, the plurality of panels including first and second top panels and a bottom panel connected to the second top panel by at least one side wall panel; and
an end closure structure for at least partially closing one of opposed ends of the tubular structure when the blank is erected into a set-up carton, the end closure structure comprising first and second top flaps connected to the first and second top panels respectively at the one of the opposed ends of the tubular structure, wherein the first and second top flaps are not directly connected to one another but through the first and second top panels; wherein the first and second top panels are hingedly connected together along a medial fold line extending between the opposed ends of the tubular structure, wherein the first and second top panels are not coplanar with one another in the set-up carton, wherein the first top panel is parallel to the bottom and wherein the second top panel is not parallel to the bottom.

12. The blank according to claim 11 wherein the first and second top flaps are separated by a gap.

13. The blank according to claim 12 , wherein the gap comprises one selected from the group consisting of a cut and a cutout.

14. The blank according to claim 12 , wherein the medial fold line extends from the gap to the other end of the tubular structure.

15. The blank according to claim 11 , wherein the at least one side wall panel comprises a first set of side wall panels.

16. The blank according to claim 15 , wherein the plurality of panels further include another bottom panel connected to the first top panel through a second set of side wall panels, and the first set of side wall panels is taller than the second set of side wall panels.
