Abstract

A closure comprises a polymeric top wall portion, a polymeric annular skirt portion, a polymeric liner and a polymeric disc. The polymeric annular skirt portion depends from the polymeric top wall portion. The annular skirt portion includes an internal thread formation for mating engagement with an external thread formation of a container. The polymeric disc has an exterior surface. The polymeric disc is located between the polymeric top wall portion and the polymeric liner. The polymeric disc includes a plurality of channels formed therein. The plurality of channels assists in allowing liquid to travel on the exterior surface of the polymeric disc and between the polymeric annular skirt portion and an external finish of a container.

Claims (20)

1. A closure comprising:

a polymeric top wall portion;

a polymeric annular skirt portion depending from the polymeric top wall portion, the annular skirt portion including an internal thread formation for mating engagement with an external thread formation of a container;

a polymeric liner; and

a polymeric disc having an exterior surface, the polymeric disc being located between the polymeric top wall portion and the polymeric liner, the polymeric disc including a plurality of channels formed therein, the plurality of channels assisting in allowing liquid to travel on the exterior surface of the polymeric disc and between the polymeric annular skirt portion and an external finish of a container, the polymeric disc having a radially outward end opposite of its center, the polymeric disc being held in place in a position within the closure at the radially outward end by an internal protrusion of the closure,

wherein the internal protrusion of the closure is the internal thread formation.

2. The closure of claim 1 , wherein the width of the plurality of channels is from about 0.005 to about 0.1 inch.

3. The closure of claim 1 , wherein the depth of the plurality of channels is from about 0.005 to about 0.025 inch.

4. The closure of claim 1 , wherein the number of the plurality of channels is from about 5 to about 50.

5. The closure of claim 1 , wherein the closure further includes a polymeric tamper-evident feature.

6. The closure of claim 1 , wherein the polymeric top wall portion, the polymeric disc and the polymeric annular skirt portion include polypropylene, the polymeric liner including thermoplastic elastomer.

7. A package comprising:

a container having a neck portion defining an opening, the container having an external thread formation on the neck portion; and

a closure configured for fitment to the neck portion of the container for closing the opening, the closure comprises a polymeric top wall portion, a polymeric liner, a polymeric disc and a polymeric annular skirt portion, the polymeric annular skirt portion depending from the polymeric top wall portion, the polymeric annular skirt portion including an internal thread formation for mating engagement with the external thread formation of the container, the polymeric disc having an exterior surface, the polymeric disc being located between the polymeric top wall portion and the polymeric liner, the polymeric disc having a radially outward end opposite of its center, the polymeric disc being held in place in a position within the closure at the radially outward end by an internal protrusion of the closure, the polymeric disc including a plurality of channels formed therein, the plurality of channels assisting in allowing liquid to travel on the exterior surface of the polymeric disc and between the polymeric annular skirt portion and the external thread formation on the neck portion of the container,

wherein the internal protrusion of the closure is the internal thread formation.

8. The package of claim 7 wherein the width of the plurality of channels is from about 0.005 to about 0.1 inch.

9. The package of claim 7 , wherein the depth of the plurality of channels is from about 0.005 to about 0.025 inch.

10. The package of claim 7 , wherein the number of the plurality of channels is from about 5 to about 50.

11. The package of claim 7 , wherein the closure further includes a polymeric tamper-evident feature.

12. The package of claim 7 , wherein the polymeric top wall portion, the polymeric disc and the polymeric annular skirt portion include polypropylene, the polymeric liner including thermoplastic elastomer.
