Abstract

Packaging including a line of weakness ( 10, 11 ) that is broken to obtain access to an article within said packaging is disclosed. A varnish or lacquer coating is applied to spaced regions ( 12 ) along the length of the line of weakness.

First claim

The invention claimed is:

1. A packaging comprising:
an overwrap with a line of weakness defining a tear strip, the line of weakness broken to obtain access to within said packaging,
the overwrap including a varnish or lacquer coating applied to extend across the line of weakness at spaced regions along the length of the tear strip, and
a container wrapped in said overwrap layer, said line of weakness being formed in said overwrap layer.

2. The packaging according to claim 1 , wherein the varnish or lacquer coating is configured to produce an audible and/or tactile signature when said line of weakness is broken.

3. The packaging according to claim 1 , wherein the regions to which a varnish or lacquer coating are applied are equispaced along the line of weakness.

4. The packaging according to claim 3 , further comprising a tab extending from an end of the tear strip that can be grasped by a user to facilitate tearing of the line of weakness.

5. The packaging according to claim 4 , wherein each spaced region along the line of weakness is elongate in shape and extends in a direction perpendicular to the direction in which the tear strip is torn.

6. The packaging according to claim 4 , wherein each region along the line of weakness is chevron shaped, with the apex of the chevron pointing in the direction in which the tear strip is torn.

7. The packaging according to claim 1 , wherein a varnish or lacquered coating is applied to spaced regions across the entire surface of the overwrap.

8. The packaging according to claim 1 , wherein the varnish or lacquer coating is water based and/or UV cured.

9. The packaging according to claim 1 , wherein said overwrap layer comprises a polymer film.

10. The packaging of claim 1 , wherein the packaging includes a pack of smoking articles.

11. A method of manufacturing packaging, comprising:
providing an overwrap for the packaging, the overwrap including a line of weakness forming a tear strip, the line of weakness broken to obtain access to within said packaging,
applying a varnish or lacquer coating to spaced regions along the length of the line of weakness such that the regions of varnish or lacquer coating extend across the line of weakness;
forming a tab at an end of the tear strip which extends outward from the overwrap.

12. An overwrap for a package, comprising:
a line of weakness formed in the overwrap defining an edge of a tear strip;
the line of weakness defining an upper section and a lower section of the overwrap;
a grasping tab extending outward from an end of the tear strip;
a plurality of spaced linear coatings applied substantially perpendicular to the direction of the line of weakness;
wherein each of the linear coatings cross the line of weakness;
the spaced linear coatings positioned on the line of weakness such that when the tear strip breaks the linear coating along the line of weakness when the tear strip is removed;
wherein the upper section of the overwrap removable from the lower section upon removal of the tear strip.
