Abstract

A closure assembly for a container is provided, the closure assembly comprising: a closure body for securing to the container to extend across and seal an opening in the container; the closure body comprising a bore therein, the bore communicating with the opening in the container and providing a conduit between the interior of the container and the exterior of the container through which product within the container may be dispensed; a closure member having a port therein, the closure member slideably mounted to the closure body and slideable between a closed position in which the port is out of alignment with the bore in the closure body and the closure member acts to close the bore in the closure member and an open position in which the port is aligned with the bore in the closure body. A measuring vessel for use with the closure assembly is also provided.

First claim

The invention claimed is:

1. A closure assembly for a container, the closure assembly comprising:
a closure body for securing to the container to extend across and seal an opening in the container;
the closure body comprising a bore therein, the bore communicating with the opening in the container and providing a conduit between the interior of the container and the exterior of the container through which product within the container may be dispensed;
a closure member having a port therein, the closure member slideably mounted to the closure body and slideable between a closed position in which the port is out of alignment with the bore in the closure body and the closure member acts to close the bore in the closure member and an open position in which the port is aligned with the bore in the closure body; and wherein the closure member is held in the closed position and is released for movement to the open position when the closure assembly is engaged with a vessel to receive dispensed product.

2. The closure assembly according to claim 1 , wherein the closure body is generally cylindrical.

3. The closure assembly according to claim 1 , wherein the bore is circular in cross-section.

4. The closure assembly according claim 1 , wherein the bore is tapered along its length.

5. The closure assembly according to claim 1 , wherein the longitudinal axis of the bore is aligned with a longitudinal axis of the closure body.

6. The closure assembly according to claim 1 , wherein the closure body comprises a closure portion for extending across the opening in the container, the bore extending through the closure portion.

7. The closure assembly according to claim 6 , wherein the closure portion is a planar body.

8. The closure assembly according to claim 7 , wherein the closure portion is a disc.

9. The closure assembly according to claim 1 , wherein the closure body comprises a first mounting portion having a thread formed thereon for engaging with a complementary thread on the container in a region of the opening of the container.

10. The closure assembly according to claim 9 , wherein the first mounting portion is tubular.

11. A closure assembly for a container, the closure assembly comprising:
a closure body for securing to the container to extend across and seal an opening in the container;
the closure body comprising a bore therein, the bore communicating with the opening in the container and providing a conduit between the interior of the container and the exterior of the container through which product within the container may be dispensed;
a closure member having a port therein, the closure member slideably mounted to the closure body and slideable between a closed position in which the port is out of alignment with the bore in the closure body and the closure member acts to close the bore in the closure member and an open position in which the port is aligned with the bore in the closure body,
further comprising a connecting structure for securing the closure body to a vessel to receive product dispensed from the container through the closure assembly when in the open position.

12. The closure assembly according to claim 11 , wherein the connecting structure comprises a second mounting portion of the closure body.

13. The closure assembly according to claim 12 , wherein the second mounting portion is tubular.

14. The closure assembly according to claim 1 , wherein the closure member is slideable laterally across the closure body.

15. The closure assembly according to claim 1 , wherein the closure member is arranged to slide across one end of the bore in the closure body.

16. The closure assembly according to claim 15 , wherein the closure member is arranged to slide across an outer end of the bore in the closure body.

17. The closure assembly according to claim 1 , wherein the port in the closure member is generally circular in at least part of its length.

18. The closure assembly according to claim 1 , wherein the closure member is a planar body.

19. The closure assembly according to claim 1 , wherein the port in the closure member is tapered along its length.

20. The closure assembly according to claim 19 , wherein the widest portion of the port is at an outer end of the port, relative to the interior of the container.

21. The closure assembly according to claim 1 , wherein the closure member is moveable through a side wall of the closure body.

22. The closure assembly according to claim 21 , wherein an outer end portion of the closure member is enlarged.

23. The closure assembly according to claim 1 , further comprising a guard member to limit or prevent inadvertent movement of the closure member.

24. A closure assembly for a container, the closure assembly comprising:
a closure body for securing to the container to extend across and seal an opening in the container;
the closure body comprising a bore therein, the bore communicating with the opening in the container and providing a conduit between the interior of the container and the exterior of the container through which product within the container may be dispensed;
a closure member having a port therein, the closure member slideably mounted to the closure body and slideable between a closed position in which the port is out of alignment with the bore in the closure body and the closure member acts to close the bore in the closure member and an open position in which the port is aligned with the bore in the closure body,
a guard member to limit or prevent inadvertent movement of the closure member, wherein the guard comprises one or more guard walls extending from the outer surface of the closure body.

25. The closure assembly according to claim 1 , wherein movement of the closure member past the open position is limited by a stop.

26. The closure assembly according to claim 1 , wherein the closure member is biased.

27. The closure assembly according to claim 26 , wherein the closure member is biased into the closed position.

28. The closure assembly according to claim 27 , wherein the closure member is biased by a resilient biasing arm.

29. The closure assembly according to claim 28 , wherein the resilient biasing arm acts between the closure body and the closure member.

30. The closure assembly according to claim 29 , wherein the resilient biasing arm is connected to the closure member.

31. The closure assembly according claim 1 , wherein movement of the closure member is limited to a substantially linear path by guide members.

32. A closure assembly for a container, the closure assembly comprising:
a closure body for securing to the container to extend across and seal an opening in the container;
the closure body comprising a bore therein, the bore communicating with the opening in the container and providing a conduit between the interior of the container and the exterior of the container through which product within the container may be dispensed;
a closure member having a port therein, the closure member slideably mounted to the closure body and slideable between a closed position in which the port is out of alignment with the bore in the closure body and the closure member acts to close the bore in the closure member and an open position in which the port is aligned with the bore in the closure body,
