Abstract

A closure is configured to mount on a container to close an open mouth formed in the container. The closure includes a lid and an outer layer coupled to the lid.

First claim

The invention claimed is:

1. A closure comprising
a rigid lid configured to close an open mouth of a container and
a skin layer coupled to the rigid lid to provide a soft grip interface for a user grasping the closure,
wherein the lid includes a top wall, a side wall coupled to the top wall and arranged to extend downwardly away from the top wall, and a brim coupled to the side wall and arranged to extend away from the side wall,
wherein the skin layer is arranged around at least a portion of the top wall and the side wall of the rigid lid, and
wherein the brim of the rigid lid is formed to include a vent aperture arranged to extend downwardly into the brim away from the top wall to allow gases and excess portions of the skin layer to move into the vent aperture during manufacture of the closure so that flashing of the skin layer is minimized, and
wherein the vent aperture extends only partway through the brim.

2. The closure of claim 1 , wherein the vent aperture extends about 20 degrees around the side wall of the lid.

3. The closure of claim 1 , wherein the skin layer comprises thermoplastic elastomer materials.

4. The closure of claim 1 , wherein the skin layer comprises thermoplastic olefin materials.

5. The closure of claim 1 , wherein the lid comprises polypropylene.

6. The closure of claim 1 , wherein the lid comprises polyethylene.

7. The closure of claim 1 , wherein the top wall is formed to include a slide rail that extends upwardly away from the top wall and the slide rail extends through the skin layer.

8. The closure of claim 7 , wherein the skin layer comprises at least one of thermoplastic elastomer materials and thermoplastic olefin materials.

9. The closure of claim 8 , wherein the rigid lid comprises at least one of polypropylene and polyethylene.

10. The closure of claim 1 , wherein the vent aperture is continuous and extends 360 degrees around the side wall of the lid.

11. A closure comprising
a rigid lid configured to close an open mouth of a container and
a skin layer coupled to the rigid lid to provide a soft grip interface for a user grasping the closure,
wherein the lid includes a top wall, a side wall coupled to the top wall and arranged to extend downwardly away from the top wall, and a brim coupled to the side wall and arranged to extend away from the side wall,
wherein the skin layer is arranged around at least a portion of the top wall and the side wall of the rigid lid, and
wherein the brim of the rigid lid is formed to include a vent aperture arranged to extend downwardly into the brim away from the top wall to allow gases and excess portions of the skin layer to move into the vent aperture during manufacture of the closure so that flashing of the skin layer is minimized, and
wherein the vent aperture is continuous and extends 360 degrees around the side wall of the lid.

12. The closure of claim 11 , wherein the vent aperture extends only partway through the brim.

13. The closure of claim 11 , wherein a portion of the vent aperture extends through an upper surface of the brim and a lower surface of the brim.

14. A closure comprising
a rigid lid configured to close an open mouth of a container and
a skin layer coupled to the rigid lid to provide a soft grip interface for a user grasping the closure,
wherein the lid includes a top wall, a side wall coupled to the top wall and arranged to extend downwardly away from the top wall, and a brim coupled to the side wall and arranged to extend away from the side wall,
wherein the skin layer is arranged around at least a portion of the top wall and the side wall of the rigid lid, and
wherein the brim of the rigid lid is formed to include a vent aperture arranged to extend downwardly into the brim away from the top wall to allow gases and excess portions of the skin layer to move into the vent aperture during manufacture of the closure so that flashing of the skin layer is minimized, and
wherein the top wall is formed to include a slide rail that extends upwardly away from the top wall.

15. The closure of claim 14 , wherein the brim includes an upper surface and a lower surface that is spaced apart from the upper surface and the vent aperture extends into the upper surface toward the lower surface.

16. The closure of claim 15 , wherein at least a portion of the skin layer extends into the vent aperture without extending beyond the lower surface.

17. The closure of claim 14 , wherein the slide rail extends through the skin layer.

18. The closure of claim 17 , wherein at least a portion of the vent aperture extends through an upper surface of the brim and a lower surface of the brim.

19. The closure of claim 17 , wherein the vent aperture extends 20 degrees around the side wall of the lid.

20. The closure of claim 14 , wherein the vent aperture is continuous and extends 360 degrees around the side wall of the lid.
