Abstract

A self-piercing closure (15) for a container of the type having a laminar closing member, the closure (15) comprising a closure body and having a piercing member (35) for piercing a closing member in use, in which the piercing member (35) comprises a depending skirt (36), and in which the closure further comprising a self-closing valve sub-assembly (50) having a retaining member which retains a self-closing valve, the sub-assembly being located within the piercing member, whereby flowable media can be dispensed from a container through the self-closing valve following piercing of the closing member in use.

Claims

1. A self-piercing closure for a container of the type having a laminar closing member, the closure comprising a closure body and having a piercing member for piercing a closing member in use, in which the piercing member is a depending piercing skirt, and in which the closure further comprising a self-closing valve sub-assembly having a retaining member which retains a self-closing valve, the sub-assembly retaining member being located within and retained by the depending piercing skirt, whereby flowable media can be dispensed from a container through the self-closing valve following piercing of the closing member in use.

2. A closure as claimed in claim 1, in which the closure body is movable from a first position to a second position to activate the piercing member in use.

3. A closure as claimed in claim 2, in which the body includes a spout movable from a raised, unactivated position to a depressed, activated position to move the closure from the first to the second position.

4. A closure as claimed in claim 2, in which the closure body comprises a deformable region for allowing it to move from the first to the second position.

6. A closure as claimed in claim 1, in which the closure comprises a base and a lid.

7. A closure as claimed in claim 6, in which the base and lid are connected together by a hinge.

8. A closure as claimed in claim 6, in hick the piercing member is provided on or by the base.

9. A closure as claimed in claim 1, in which the retaining member comprises a body for receiving a self-closing valve, the body being receivable into the piercing member with the valve retained.

10. A closure as claimed in claim 9, in which the retaining member body has a crimping flange capable of being bent from an uncrimped position to a crimped position to retain the valve in the device.

11. A closure as claimed in claim 10, in which the crimping flange comprises an upstanding wall.

12. A closure as claimed in claim 1, in which the retaining member comprises a bead for snap-fitting the retaining member into the piercing skirt.

13. A closure as claimed in claim 1, in which the retaining member is formed as a retaining ring.

14. A closure as claimed in claim 1, in which the retaining member is formed as a single-piece article.

15. A closure as claimed in claim 1, in which the body comprises an outer skirt and an inner skirt.

16. A closure as claimed in claim 1, in which the piercing member is a generally annular piercing skirt the free end of which is inclined to form a cutting blade.

25. A method of forming a self-piercing closure as claimed in claim 2, the method comprising the steps of:

forming the closure body in the second position or in a position intermediate the first and second positions; and

moving the closure body to the first position.

26. A method as claimed in claim 25, further comprising the step of fitting a self-closing valve sub-assembly into the body.

27. A method as claimed in claim 25, in which the body is moulded from a thermoplastics material.

28. A method as claimed in claim 25, which the body is moulded in the second position and then moved to the first position before it has cooled.

22. A self-piercing closure in combination with a container of the type having a laminar closing member, the closure comprising a closure body and having a piercing member for piercing a closing member in use, in which the piercing member comprises a depending skirt, said skirt extending into the interior of the closure body, and in which the closure further comprising a self-closing valve sub-assembly having a retaining member which retains a self-closing valve, the sub-assembly being housed inside and retained by the depending skirt, the sub-assembly retaining the valve independently of the depending skirt, whereby flowable media can be dispensed from a container through the self-closing valve following piercing of the laminar closing member in use.
