Abstract

The invention provides a cigarette pack comprising an inner slide 13, having a hinged lid, slidable in an outer shell 11. The inner slide has a tongue 39, formed into a first hook, cut from its rear wall 19 and depending from the top wall 21 of the lid of the inner slide. On the inner slide being pushed up and partially out of the outer shell, the first hook engages with a flap 67 formed into a second hook on the rear wall 61 of the outer shell. The action of the tongue on the lid of the inner slide causes it to open, exposing the cigarettes within the pack.

Claims

1. A pack of smoking articles comprising an inner slide and an outer shell, said inner slide comprising:

a bottom wall;

opposed side walls and a rear wall extending from said bottom wall and comprising upper and lower portions, said rear wall having an upper edge; and

a top wall attached to said upper edge of said rear wall along a first fold line, said top wall forming, together with said upper portion of said rear wall, a lid;

wherein a first tongue is formed of both said upper and lower portions of said rear wall and is attached to said inner slide at its upper end, said first tongue having upper and lower ends, said lower end of said tongue being folded toward said lid to form a first hook, said first tongue being formed of an upper tongue portion and a lower tongue portion wider than said upper tongue portion, and wherein said lower tongue portion is folded towards said lid of said inner slide to form said first hook; and

said outer shell comprising opposed side shell walls and opposed front and rear shell walls, and a flap extending from said upper edge of said rear shell wall folded inside said shell to form a second hook for engagement with said first hook of said inner slide, whereby, when said inner slide is inside said outer shell and is moved upwards, said first hook engages said second hook to cause said lid of said inner slide to open along a second fold line extending across said rear wall of said inner slide between said upper and lower portions thereof.

3. A pack according to claim 1 wherein said top wall of said inner slide is wider than said rear wall of said outer shell, for preventing said top wall of said inner slide from passing into said outer shell.

2. A pack according to claim 2 wherein a front flap depends from the front edge of said top wall of said inner slide.

6. A pack according to claim 2 wherein a front flap depends from the front edge of said top wall of said inner slide.

7. A pack according to claim 2 wherein said top wall of said inner slide is wider than said rear wall of said outer shell, for preventing said top wall of said inner slide from passing into said outer shell.

4. A pack of smoking articles comprising an inner slide and an outer shell, said inner slide comprising:

a bottom wall;

opposed side walls and a rear wall extending from said bottom wall and comprising upper and lower portions, said rear wall having an upper edge; and

a top wall attached to said upper edge of said rear wall along a first fold line, said top wall forming, together with said upper portion of said rear wall, a lid;

wherein a first tongue is formed of both said upper and lower portions of said rear wall and is attached to said inner slide at its upper end, said first tongue having upper and lower ends, said lower end of said tongue being folded toward said lid to form a first hook, said first tongue being attached to said inner slide at said first fold line, and wherein said first fold line, where it crosses said first tongue, is displaced toward said lower portion of said rear wall of said inner slide, whereby said top wall of said inner slide is provided, on its rear edge, with a protruding lip from which said first tongue depends; and

said outer shell comprising opposed side shell walls and opposed front and rear shell walls, and a flap extending from said upper edge of said rear shell wall folded inside said shell to form a second hook for engagement with said first hook of said inner slide, whereby, when said inner slide is inside said outer shell and is moved upwards, said first hook engages said second hook to cause said lid of said inner slide to open along a second fold line extending across said rear wall of said inner slide between said upper and lower portions thereof.

5. A pack according to claim 4 wherein said lid of said inner slide is provided with a reinforcing piece extending under said lip.

8. A pack of smoking articles comprising an inner slide and an outer shell, said inner slide comprising:

a bottom wall;

opposed side walls and a rear wall extending from said bottom wall and comprising upper and lower portions, said rear wall having an upper edge; and

a top wall attached to said upper edge of said rear wall along a first fold line, said top wall forming, together with said upper portion of said rear wall, a lid;

wherein a first tongue is formed of both said upper and lower portions of said rear wall and is attached to said inner slide at its upper end, said first tongue having upper and lower ends, said lower end of said tongue being folded toward said lid to form a first hook, a further tongue being formed in said lower portion of said rear wall of said inner slide and being bent portion of said rear wall of said inner slide and being bent toward said lid of said inner slide to form a stopping tab for engagement with said second hook on said rear wall of said outer shell when said lid is fully opened; and

said outer shell comprising opposed side shell walls and opposed front and rear shell walls, and a flap extending from said upper edge of said rear shell wall folded inside said shell to form a second hook for engagement with said first hook of said inner slide, whereby, when said inner slide is inside said outer shell and is moved upwards, said first hook engages said second hook to cause said lid of said inner slide to open along a second fold line extending across said rear wall of said inner slide between said upper and lower portions thereof.

9. A pack according to claim 8 wherein a front flap depends from the front edge of said top wall of said inner slide.

10. A pack according to claim 8 wherein said top wall of said inner slide is wider than said rear wall of said outer shell, for preventing said top wall of said inner slide from passing into said outer shell.
