Abstract

A container for consumer goods and a laminar blank (300) for forming such a container. The laminar blank defines a portion of the container, which comprises: a first planar wall (322); a second planar wall (314) connected to the first planar wall (322) by a first modified edge portion (3140) forming a bevelled edge portion of the container; and a third planar wall (316) connected to the first planar wall (322) by a second modified edge portion (3130) forming a curved edge portion of the container. The longitudinal direction of the first modified edge portion (3140) being transverse to the longitudinal direction of the second modified edge portion (3130); the first modified edge portion (3140) and the second modified edge portion (3130) forming, when the container is assembled from the laminar blank, adjacent edge portions of the container meeting at a junction.

First claim

The invention claimed is:

1. A container for consumer articles, the container being at least partially formed from a laminar blank, the laminar blank defining a portion of the container, which comprises:
a first planar wall;
a second planar wall connected to the first planar wall by a first modified edge portion forming a bevelled edge portion of the container; and
a third planar wall connected to the first planar wall by a second modified edge portion forming a curved edge portion of the container;

the longitudinal direction of the first modified edge portion being transverse to the longitudinal direction of the second modified edge portion; the first modified edge portion and the second modified edge portion forming, when the container is assembled from the laminar blank, adjacent edge portions of the container meeting at a junction;
wherein each of the first modified edge portion and the second modified edge portion has a length in the longitudinal direction of the respective modified edge portion and a respective width that extends transversely to the length;
wherein the first modified edge portion has a perimeter, the perimeter comprising:
a first line of weakness and a second line of weakness each extending in the longitudinal direction of the first modified edge portion, and
a free edge extending between a tip of the first line of weakness and a tip of the second line of weakness at the junction with the second modified edge portion;

wherein the second modified edge portion has a perimeter, the perimeter comprising:
a first line of weakness and a second line of weakness each extending in the longitudinal direction of the second modified edge portion, and
a free edge extending between the tip of the first line of weakness and the tip of the second line of weakness at the junction with the first modified edge portion; and

wherein the free edge of at least one of the first modified edge portion and the second modified edge portion comprises a curved free edge portion and a straight free edge portion.

2. A container according to claim 1 , wherein the free edge of the first modified edge portion comprises a curved free edge portion and a straight free edge portion.

3. A container according to claim 2 , wherein the straight free edge portion extends from the first line of weakness of the first modified edge portion, and wherein the curved free edge portion extends from the straight free edge portion.

4. A container according to claim 2 , wherein the first line of weakness of the first modified edge portion comprises a straight portion and a curved portion.

5. A container according claim 4 , wherein the curved portion-of the first line of weakness defines the tip of the first line of weakness.

6. A container according to claim 2 , wherein the free edge of the second modified edge portion has a substantially s-shaped profile.

7. A container according to claim 1 , wherein the free edge of the second modified edge portion comprises a curved free edge portion and a straight free edge portion.

8. A container according to claim 7 , wherein the straight free edge portion extends from the second line of weakness of the second modified edge portion, and wherein the curved free edge portion extends from the straight free edge portion.

9. A container according to claim 7 , wherein each of the first line of weakness and the second line of weakness of the first modified edge portion is substantially straight.

10. A container according to claim 1 , wherein the second modified edge portion further comprises a plurality of additional lines of weakness disposed between the first line of weakness and the second line of weakness of the second modified edge portion, the plurality of additional lines of weakness extending substantially in the longitudinal direction of the second modified edge portion.

11. A container according to claim 10 , wherein the plurality of additional lines of weakness of the second modified edge portion comprise a third line of weakness, and wherein the free edge of the second modified edge portion extends from the third line of weakness.

12. A container according to claim 11 , wherein the third line of weakness is disposed adjacent to the first line of weakness of the second modified edge portion.

13. A container according to claim 1 , wherein the lines of weakness of the first modified edge portion are a plurality of ablated lines on the inner surface of said modified edge portion.

14. A container according to claim 1 , wherein the lines of weakness of the second modified edge portion are a plurality of creasing lines in the laminar blank.

15. A laminar blank for forming a container for consumer articles, the laminar blank comprising:
a first planar wall;
a second planar wall connected to the first planar wall by a first modified edge portion forming a bevelled edge portion of the container; and
a third planar wall connected to the first planar wall by a second modified edge portion forming a curved edge portion of the container;

the longitudinal direction of the first modified edge portion being transverse to the longitudinal direction of the second modified edge portion; the first modified edge portion and the second modified edge portion forming, when the container is assembled from the laminar blank, adjacent edge portions of the container meeting at a junction;
wherein each of the first modified edge portion and the second modified edge portion has a length in the longitudinal direction of the respective modified edge portion and a respective width that extends transversely to the length;
wherein the first modified edge portion has a perimeter, the perimeter comprising:
a first line of weakness and a second line of weakness each extending in the longitudinal direction of the first modified edge portion, and
a free edge extending between a tip of the first line of weakness and a tip of the second line of weakness at the junction with the second modified edge portion;

wherein the second modified edge portion has a perimeter, the perimeter comprising:
a first line of weakness and a second line of weakness each extending in the longitudinal direction of the second modified edge portion, and
a free edge extending between the tip of the first line of weakness and the tip of the second line of weakness at the junction with the first modified edge portion; and

wherein the free edge of at least one of the first modified edge portion and the second modified edge portion comprises a curved free edge portion and a straight free edge portion.
