Abstract

Aspects of the disclosure relate to a package, a carton (190), and a blank (110) for forming the carton. An aspect of the invention provides a carton comprising a plurality of primary panels (112, 114, 116, 118, 120) defining an interior of the carton. The carton comprises a first panel (118) and a second panel (120) hinged to the first panel along a first fold line (119). The first panel has a first corner edge (55a) extending obliquely with respect to the first fold line such that an obtuse angle is defined between the first corner edge and the first fold line. The carton further comprises an opening feature (D) which is at least partially removable from the carton. The opening feature comprises a removable panel (170a) defined at least in part by first (173a) and second tear lines (173b) which define opposing side edges of the removable panel respectively.

First claim

The invention claimed is:

1. A carton for packaging one or more articles, the carton comprising: a first panel and a second panel hinged to the first panel along a first fold line, the first panel having a first corner edge extending obliquely with respect to the first fold line such that an obtuse angle is defined between the first corner edge and the first fold line, the carton further comprising an opening feature which is at least partially removable from the carton, the opening feature comprising a removable panel defined at least in part by a first tear line and a second tear line which define opposing side edges of the removable panel respectively, the first and second tear lines each extending from the first fold line into the first panel, the first tear line being located closer to the first corner edge than the second tear line, wherein a first notional line is interposed between the first and second tear lines such that the first notional line is disposed at a right angle with respect to each of the first fold line and a second fold line in the second panel, wherein a first acute angle is defined between the first notional line and the first corner edge, wherein a second acute angle is defined between the first notional line and at least part of the first tear line and wherein the first acute angle is equal to or greater than the second acute angle.

2. The carton of claim 1 wherein a third acute angle is defined between the first notional line and at least part of the second tear line and wherein the first acute angle is equal to or greater than the third acute angle.

3. The carton of claim 2 wherein the second acute angle is generally equal to the third acute angle.

4. The carton of claim 1 wherein the first panel has a second corner edge extending obliquely with respect to the first fold line such that an obtuse angle is defined between the second corner edge and the first fold line, the removable panel being disposed between the first and second corner edges, wherein a fourth acute angle is defined between the first notional line and the second corner edge, wherein a third acute angle is defined between the first notional line and at least part of the second tear line and wherein the fourth acute angle is equal to or greater than the third acute angle.

5. The carton of claim 1 wherein each of the first and second tear lines extends across the first fold line into the second panel.

6. The carton of claim 5 wherein the opening feature further comprises a tear initiation feature defined in the second panel and wherein the first and second tear lines each extends from the tear initiation feature.

7. The carton of claim 1 further comprising a group of generally cylindrical articles each having an end and a cylindrical axis, the group of articles being received in an interior of the carton such that cylindrical axes of the articles extend generally perpendicularly to a plane of the first panel, the group of articles being arranged in a plurality of rows of articles comprising a first row and a second row, the first row extending along the second panel, the second row being disposed along the first row such that the articles of the second row are nested with the articles of the first row, wherein a second notional line extends between a centre of the end of one of the articles in the first row and a centre of the end of an adjacent one of the articles in the second row and wherein a fifth angle defined between the second notional line and the first notional line is generally equal to the second acute angle.

8. The carton of claim 7 wherein the fifth angle is generally equal to the third acute angle.

9. The carton of claim 1 wherein the first corner edge extends obliquely into the first panel with respect to the first fold line.

10. The carton of claim 1 wherein a portion of the first tear line extends from a first location on the first fold line to a first end of a tear initiator in the second panel.

11. The carton of claim 10 wherein a portion of the second tear line extends from a second location on the first fold line to a second end of the tear initiator in the second panel.

12. The carton of claim 11 wherein the tear initiator comprises a foldable tab hinged to a portion of the removable panel by the second fold line in the second panel.

13. A carton for packaging one or more articles, the carton comprising: a plurality of main or primary panels defining an interior of the carton including a first panel and a second panel hinged to the first panel along a first fold line, the first panel having a first corner edge extending obliquely with respect to the first fold line such that a first, obtuse, angle is defined between the first corner edge and the first fold line, the carton comprising an opening feature which is at least partially removable from the carton, the opening feature comprising a removable panel defined at least in part by a first tear line and a second tear line which define opposing side edges of the removable panel respectively, the first and second tear lines each extending from the first fold line into the first panel, wherein the first tear line is located closer to the first corner edge than the second tear line, a first notional line is interposed between the first and second tear lines such that the first notional line is disposed at a right angle with respect to each of the first fold line and a second fold line in the second panel, a second, acute, angle is defined between the first notional line and at least part of the first tear line, the carton comprises a group of generally cylindrical articles each having an end and a cylindrical axis, the group of articles is received in an interior of the carton such that cylindrical axes of the articles extend generally perpendicularly to a plane of the first panel, the group of articles is arranged in a plurality of rows of articles comprising a first row and a second row, the first row extends along the second panel, the second row is disposed along the first row such that the articles of the second row are nested with the articles of the first row, a second notional line extends between a centre of the end of one of the articles in the first row and a centre of the end of an adjacent one of the articles in the second row, a third angle is defined between the second notional line and a first notional line, the third angle is generally equal to a second, acute, angle.

14. The carton of claim 13 wherein a fourth, acute, angle is defined between the first notional line and at least part of the second tear line, the third angle is generally equal to the fourth, acute, angle.

15. The carton of claim 13 wherein the first corner edge extends obliquely into the first panel with respect to the first fold line.

16. The carton of claim 13 wherein a portion of the first tear line extends from a first location on the first fold line to a first end of a tear initiator in the second panel and portion of the second tear line extends from a second location on the first fold line to a second end of the tear initiator in the second panel.

17. A blank for forming a carton, the blank comprising a plurality of primary panels for defining an interior of the carton, the plurality of primary panels comprising:
a first panel; and
a second panel hinged to the first panel along a first fold line;
the first panel having a first corner edge extending obliquely with respect to the first fold line such that an obtuse angle is defined between the first corner edge and the first fold line, the blank further comprising:
