Abstract

A security closure 5 for a container neck 40 comprises a body 25 formed from a plastics material and a metal retention member 10 formed integrally with the body 25 . The metal retention member 10 remains on the container neck 40 for retaining the body 25 on the container neck 40 . The metal retention member 10 makes it impossible or very difficult to remove the security closure 5 from the container neck 40 without breaking/damaging/destroying the container. The security closure 5 and a container having a container neck 40 , and a method of forming the security closure 5 are also disclosed.

First claim

The invention claimed is:

1. A security closure for a container neck, the security closure comprising a body formed from a plastics material, and
a metal retention member formed integrally and irremovably with the body, the metal retention member arranged in use to irremovably remain on a container neck for retaining the body on the container neck to prevent removal of the body from the container neck.

2. The security closure of claim 1 , wherein the body is formed as a pouring body fitment comprising a lower engagement portion and an upper flow regulation portion.

3. The security closure of claim 2 , wherein an additional flow regulation component is positioned in the pouring fitment body.

4. The security closure of claim 1 , wherein the body is formed from polycarbonate.

5. The security closure of claim 1 , wherein the metal retention member is formed from steel.

6. The security closure of claim 1 , wherein the body has a wall thickness with a hollow section.

7. The security closure of claim 6 , wherein the body is a gas assisted injection molded structure.

8. A method of forming the security closure of claim 6 , comprising a step of forming the body by a gas assisted injection molding process.

9. The security closure of claim 1 and a container having a container neck.

10. The security closure of claim 9 , wherein the container is a glass bottle.

11. The security closure of claim 9 , wherein the security closure is snap-fitted onto the container neck.

12. The security closure of claim 9 , wherein a shell is fitted over the body.

13. The security closure of claim 1 , wherein the metal retention member is a generally annular metal retention insert.

14. The security closure of claim 13 , wherein the generally annular metal retention insert comprises a band and a plurality of spaced upright tabs interspersed by a plurality of inclined retention flaps.

15. The security closure of claim 14 , wherein the body comprises body ledges for locking under a neck finish bead of a container neck and the inclined retention flaps of the generally annular metal retention insert extend into the body ledges of the body.

16. The security closure of claim 1 , wherein the body is molded around the metal retention member.

17. A method of forming the security closure of claim 1 , comprising a step of molding the body around the metal retention member.
