A leak-proof closure (10) for dispensing liquid beverages from a container. The closure (10) contains a outlet passage (14) which is open at both ends. Within outlet passage (14) there is a membrane (13) which denies communication between the interior of the container and the flow opening (15). When

A leak-proof closure (10) for dispensing liquid beverages from a container. The closure (10) contains a outlet passage (14) which is open at both ends. Within outlet passage (14) there is a membrane (13) which denies communication between the interior of the container and the flow opening (15). When external suction is applied to the end of outlet passage (14), membrane (13) sealingly disengages from circumferential seal member (12). This allows the contained beverage to egress through the flow opening (15). When the external suction is removed, membrane (13) automatically sealingly engages with circumferential seal member (12).

The clutch according to claim 1, wherein the first and second members are positioned concentric with and radially outwardly of the transmission input shaft. 3. The clutch according to claim 1, wherein the second member includes a shaft-like structure and an engagement portion for securing the second member to the cover assembly. 4. The clutch according to claim 3, wherein the first member is slidably disposed on the shaft-like structure of the second member. 5. The clutch according to claim 1, wherein the first member includes a first cam surface and the second member includes a second cam surface, the first cam surface configured to engage the second cam surface to convert rotative movement of the first member relative to the second member into axial movement. 6. The clutch according to claim 5, wherein the first and second cam surfaces comprise an inclined ramp. 7. The clutch according to claim 5, wherein the first member includes at least one lug positioned proximate the first cam surface and the second member includes at least one slot proximate the second cam surface, the slot configured to receive the lug of the first member to limit the degree of rotation of the first member relative to the second member. 8. The clutch according to claim 1, wherein the first member includes a land and a plurality of cam surfaces disposed radially outward of the land. 9. The clutch according to claim 8, wherein the second member is a circular plate having a plurality of integrally formed cam members extending therefrom that are configured in size and position to engage the cam surfaces of the first member to convert rotative movement of the first member relative to the second member into axial movement. 10. The clutch according to claim 9, wherein the first member includes a lug positioned proximate each cam surface and the second member includes at tab positioned proximate each cam member, each tab configured to engage a corresponding lug on the first member to limit the degree of rotation of the first member relative to the second member. 11. The clutch according to claim 1 further including a resilient member disposed between the first member and the cover assembly. 12. The clutch according to claim 11, wherein the resilient member is a circumferentially acting torsion spring. 13. The clutch according to claim 11, wherein the resilient member is an axially compressible spring. 14. The clutch according to claim 13, wherein rotation of the first member relative to the second member causes said the first member to move in an axial direction away from the second member. 15. The clutch according to claim 14, wherein the axial movement of the first member relative to the second member in a direction away from the second member compresses the resiliently compressible member. 16. The clutch according to claim 1, wherein the first member includes a polygonal engagement feature to facilitate rotation of the first member relative to the second member. 17. A method of installing a centrifugal master friction clutch in a vehicle drive-train system, the centrifugal master friction clutch including an input portion fixed for rotation with an engine flywheel and an output portion fixed for rotation with a transmission input shaft, the output portion comprising at least one friction plate secured to the transmission input shaft for rotation therewith, the input portion
