This invention provides a valve for a flowable material. The valve has a body defining a bore defined therein. An opening is defined in the side of the bore for material to flow from the bore. The valve also has an actuatable member which is movable along the bore to control the extent of an uncovered area of the opening defined in the bore to control the flow of material through the opening.

1. A valve for a flowable material, said valve comprising: a body having a bore formed therein, the bore having a flow opening on a side of the bore;an actuatable member (i) having an end portion protruding outwardly from the bore and (ii) movable along the bore to open or close the flow opening in an open position or in a closed position, respectively; anda diaphragm seal engageable with the actuatable member, said diaphragm seal including a first portion covering the end portion of the actuatable member and a second portion circumferentially extending around the first portion,whereinthe second portion of the diaphragm seal is directly abutted against an end of the body in the closed position to stop the flow of the material within the valve,the first portion of the diaphragm seal is directly abutted against the end portion of the actuatable member and the end of the body in the open position so as to stop the material from being transferred through the diaphragm seal,the diaphragm seal is deformable, andthe diaphragm seal is folded to define two folds between the body and the actuatable member when the actuatable member is in the open position. 2. The valve as claimed in claim 1, wherein the actuatable member has an outer profile of a complementary shape to said bore. 3. The valve as claimed in claim 1, wherein the diaphragm seal comprises a rib. 4. The valve as claimed in claim 3, wherein the rib is formed on the actuatable member. 5. The valve as claimed in claim 1, wherein the diaphragm seal is configured to bias the actuatable member towards the closed position where the actuatable member fully covers said flow opening and prevents the flow of material from passing through the flow opening. 6. The valve as claimed in claim 1, wherein the body includes an opening allowing the actuatable member to protrude therethrough. 7. The valve as claimed in claim 6, further comprising a cover adapted to be connected to the body and sit over the actuatable member. 8. The valve as claimed in claim 7, further comprising a pull tab connected to the cover. 9. The valve as claimed in claim 7, wherein the body includes an overhang in the vicinity of the opening for the actuatable member. 10. The valve as claimed in claim 7, wherein said cover comprises: an actuatable member covering portion adapted to cover the actuatable member;a plug adapted to close the flow opening; anda web portion connecting said actuatable member covering portion and said plug. 11. The valve as claimed in claim 6, further comprising a cover adapted to be connected to the body and cover the actuatable member, said cover including tamper evident elements which are breakable to allow part of the cover to be removed from the body to expose the actuatable member. 12. The valve as claimed in claim 1, wherein the diaphragm seal comprises a biasing element biasing the actuatable member forward to the closed position. 13. The valve as claimed in claim 1, wherein the diaphragm seal is formed from an elastomer material. 14. The valve as claimed in claim 1, wherein the body and diaphragm seal are formed with co-operating or complementary shapes at regions at which the body and the diaphragm seal abut. 15. The valve as claimed in claim 1, wherein the diaphragm seal defines a recess to receive the end portion of the actuatable member. 16. The valve as claimed in claim 1, wherein the end portion of the actuatable member includes a button. 17. The valve as claimed in claim 16, further comprising at least one projection formed on the body and projecting substantially transverse to the button which is adapted for a user to grip when depressing the button. 18. The valve as claimed in claim 1, wherein the body includes at least one guard protrusion positioned adjacent to the actuatable member and extending substantially in a moving direction of said actuatable member. 19. A valve for a flowable material, said valve comprising: a body having a bore formed therein, the bore having a flow opening on a side of the bore;an actuatable member (i) having an end portion protruding outwardly from the bore and (ii) movable along the bore to open or close the flow opening in an open position or in a closed position, respectively; anda diaphragm seal engageable with the actuatable member, said diaphragm seal including a first portion covering the end portion of the actuatable member and a second portion circumferentially extending around the first portion,whereinthe second portion of the diaphragm seal is directly abutted against an end of the body in the closed position to stop the flow of the material within the valve,the first portion of the diaphragm seal is directly abutted against the end portion of the actuatable member and the end of the body in the open position so as to stop the material from being transferred through the diaphragm seal,the diaphragm seal is deformable, andwherein the diaphragm seal is adapted to be fitted within an end of the bore. 20. The valve as claimed in claim 19, further comprising at least one rib or groove between the diaphragm seal and the bore so as to fasten the diaphragm seal within the bore. 21. The valve as claimed in claim 20, further comprising at least one further rib or groove between the diaphragm seal and the actuatable member to fasten the diaphragm seal over the actuatable member. 22. A valve for a flowable material, said valve comprising: a body having a bore formed therein, the bore having a flow opening on a side of the bore;an actuatable member (i) having an end portion protruding outwardly from the bore and (ii) movable along the bore to open or close the flow opening in an open position or in a closed position, respectively; anda diaphragm seal engageable with the actuatable member,whereinthe diaphragm seal is directly abutted against the body in the closed position to stop the flow of the material within the valve,the diaphragm seal is directly abutted against the end portion of the actuatable member in the open position so as to stop the material from being transferred through the diaphragm seal, andthe actuatable member includes at least one conduit formed therethrough. 23. The valve as claimed in claim 22, wherein, when the flow opening is not covered by the actuatable member, a flow-path for the material is provided through the actuatable member. 24. The valve as claimed in claim 22, further comprising an outlet conduit connected to the conduit of the actuatable member and extending from the flow opening, said outlet conduit adapted to direct flowable material away from the flow opening. 25. The valve as claimed in claim 24, wherein the outlet conduit is inclined to the body. 26. The valve as claimed in claim 25, wherein the outlet conduit is inclined at substantially 45 degrees to a central axis of the bore. 27. The valve as claimed in claim 24, further comprising a removable membrane over an end of the outlet conduit for sealing the outlet conduit. 28. A valve for a flowable material, said valve comprising: a body having a bore formed therein, the bore having a flow opening on a side of the bore;an actuatable member (i) having an end portion protruding outwardly from the bore and (ii) movable along the bore to open or close the flow opening in an open position or in a closed position, respectively; anda diaphragm seal engageable with the actuatable member, said diaphragm seal including a first portion covering the end portion of the actuatable member and a second portion circumferentially extending around the first portion,whereinthe second portion of the diaphragm seal is directly abutted against an end of the body in the closed position to stop the flow of the material within the valve,the first portion of the diaphragm seal is directly abutted against the end portion of the actuatable member and the end of the body in the open position so as to stop the material from being transferred through the diaphragm seal,the diaphragm seal is deformable,the second portion of the diaphragm seal is folded onto itself when the actuatable member is in the open position where the actuatable member does not cover the flow opening, and the second portion of the diaphragm seal is folded onto itself inwardly to define a fold between the body and the actuatable member in a direction perpendicular to a moving direction of the actuatable member when the actuatable member is in the open position.
