A container or vial (1) for a fluid, the container (1) comprising a casing defining an interior for storage of the fluid and a closure member (2). The closure member (2) comprises a body and at least one resilient projection (7) to seal in a storage condition an outlet of the casing, wherein upon an increase in the pressure of the interior of the container (1) the at least one resilient projection (7) is deflected to accommodate outflow of fluid through the outlet. The pressure in the interior of the container (1) may be increased by displacing the closure member (2) into the container (1) or by displacing some other element such as a bung (61, 82) into the container (1). The container (1) and closure member (2) may be used in a dispenser (90) and the closure element may be used in a valve (110).

The invention claimed is: 1. A dispenser comprising a container for a fluid, the container comprising a casing defining an interior for storage of the fluid and a closure member, and a plunger for displacing the closure member relative to the container, the closure member comprising a body, at least one resilient projection, an outlet port and a sealing portion, the at least one resilient projection sealing the casing in a storage condition, and the outlet port being disposed between the at least one resilient projection and the sealing portion, wherein the sealing portion and the at least one resilient projection are in sealing engagement with the casing, wherein the closure member including the sealing portion is displaceable relative to the casing wherein, in use, displacement of the closure member increases the pressure in the interior of the container and, upon an increase in the pressure of the interior of the container the at least one resilient projection is deflected to accommodate outflow of fluid between the casing and the at least one resilient projection through the outlet port. 2. A dispenser according to claim 1, wherein the at least one resilient projection extends substantially radially outwardly from the body of the closure member in an unbiased condition. 3. A dispenser according to claim 1, wherein the at least one resilient projection, in an unbiased condition, has a larger transverse dimension than the interior of the casing. 4. A dispenser as claimed in claim 1, wherein the at least one resilient projection extends circumferentially around the body of the closure member. 5. A dispenser according to claim 1, wherein the closure member seals with the interior of the casing. 6. A dispenser according to claim 1, wherein the at least one resilient projection comprises three resilient projections. 7. A dispenser according to claim 1, wherein the at least one resilient projection has a conical flange configuration. 8. A dispenser according to claim 1, the sealing portion comprising three sealing portions. 9. A dispenser according to claim 1, wherein the closure member and the sealing portion are connected to each other. 10. A dispenser according to claim 9, wherein said sealing portion extends circumferentially around the body of the closure member. 11. A dispenser according to claim 1, wherein the closure member is displaceable relative to the casing wherein, in use, displacement of the closure member increases the pressure in the interior of the container to a point where deflection of a circumferential extension of said at least one resilient projection occurs to feed the outlet port provided in said body while said sealing portion maintains a seal with said casing. 12. A dispenser according to claim 1, wherein the sealing portion is displaceable relative to the casing wherein, in use, displacement of the sealing portion increases the pressure in the interior of the container. 13. A dispenser as claimed in claim 1, wherein the outlet port further comprises a channel for the outflow of fluid, said channel having at least one inlet port in fluid communication with the interior of the container when said at least one resilient projection is deflected. 14. A dispenser according to claim 13, wherein said channel comprises an interconnected axial conduit and transverse conduit, and the at least one inlet port is defined at each end of the transverse conduit. 15. A dispenser according to claim 1, wherein the closure member is made of an elastomer blend, thermoplastic elastomer or a polymer. 16. A dispenser according to claim 15, wherein the elastomer has a Poisson's ratio of less than or equal to 0.5. 17. A dispenser according to claim 1, wherein the closure member has a closed cell foam structure. 18. A dispenser according to claim l, wherein said container is a vial for medicament. 19. A dispenser according to claim 1, wherein said plunger is designed for displacing the closure member and the at least one sealing portion relative to the container. 20. A dispenser according to claim 1, wherein the closure member is separate from the plunger and sealingly engages an end of said plunger in use. 21. A dispenser according to claim 1, wherein the plunger has a conical flange. 22. A dispenser according to claim 1, wherein the plunger has a delivery channel for delivering the outflow of fluid from the outlet port. 23. A container for a fluid, the container comprising a casing defining an interior for storage of the fluid and a closure member, and a plunger for displacing the closure member relative to said casing, the closure member comprising at least one resilient projection and a sealing portion; the closure member being suitable for sealing an outlet port disposed between the at least one resilient projection and the sealing portion, the at least one resilient projection sealing in a storage condition the outlet port, and the sealing portion and the at least once resilient projection are in sealing engagement with the casing, wherein the closure member including the sealing portion is displaceable relative to the casing wherein, in use, displacement of the closure member increases the pressure in the interior of the container and, upon an increase in the pressure of the interior of the container, the at least one resilient projection is deflected to accommodate outflow of fluid between the casing and the at least one resilient projection through the outlet port. 24. A container according to claim 23, wherein the at least one resilient projection extends circumferentially around the body of the closure member. 25. A container according to claim 23, wherein the at least one resilient projection comprises three resilient projections. 26. A container according to claim 23, wherein the outlet port comprises a channel for the outflow of fluid. 27. A container according to claim 26, wherein said channel comprises an interconnected axial conduit and a transverse conduit. 28. A container according to claim 27 wherein an inlet port is defined at each end of the transverse conduit of the channel. 29. A container according to claim 23, wherein the sealing portion has a convex exterior surface. 30. A container according to claim 23, wherein the sealing portion comprises three sealing portions. 31. A container according to claim 23, wherein the at least one resilient projection further comprises a plurality of resilient projections which each have a conical flange configuration. 32. A container according to claim 23, wherein said closure member comprises, on a common body, said at least one resilient projection and said sealing portion. 33. A container according to claim 23, wherein there are a plurality of each of said at least one resilient projection and sealing portions on said body.
