A dispenser for dispensing a substance, such as a liquid lipstick or other cosmetic, pharmaceutical or cosmeceutical product, has a body with a variable-volume storage chamber for storing the product. A dispensing portion is connected with the body and a one-way valve for dispensing amounts of product therethrough. The dispensing portion defines a compression chamber in fluid communication with the storage chamber for receiving product therefrom, and an outlet aperture coupled in fluid communication with the compression chamber. The one-way valve has a valve seat, and a visco-elastic valve cover seated on the valve seat and defining a normally-closed, axially-extending seam therebetween forming a fluid-tight seal between the valve cover and valve seat. The flexible valve cover is movable relative to the valve seat, and the seam is connectable in fluid communication with the outlet aperture to allow the passage of product through the seam and out of the dispenser. An actuator is drivingly connected to the compression chamber for pressurizing product within the compression chamber and dispensing an amount of product within the compression chamber.

1. A device for aseptically receiving fluid therein and passing fluid out of the device comprising: a sterile chamber having a normally sealed inlet at one end thereof defined by a valve through which fluid enters the chamber, and an outlet for passing fluid out of the chamber,wherein the valve comp
1. A device for aseptically receiving fluid therein and passing fluid out of the device comprising: a sterile chamber having a normally sealed inlet at one end thereof defined by a valve through which fluid enters the chamber, and an outlet for passing fluid out of the chamber,wherein the valve comprises a valve seat and a valve member and is configured to be moveable between (i) a normally closed position, wherein the valve member is sealingly engaged with the valve seat, and, in turn, forms a fluid-tight seal therebetween, and (ii) an open position, wherein the valve member is disengaged from the valve seat, and, in turn, permits fluid at the inlet to flow through the valve and into the chamber but prevents ingress through the valve of germs, bacteria or unwanted substances, andwherein fluid within the chamber is maintained sealed with respect to ambient atmosphere during passing of said fluid through the outlet of the device. 2. A device as define in claim 1, wherein the valve member comprises an elastomeric material. 3. A device as defined in claim 1, wherein the valve further comprises at least one fluid-flow aperture for the passage of fluid from the inlet therethrough and into the chamber when the valve is in the open position. 4. A device as defined in claim 1, wherein the device is slidably engageable by a filling probe in fluid communication with a source of fluid and adapted to move the valve from the normally closed position to the open position, and, in turn, introduce fluid at the inlet, through the valve and into the chamber. 5. A device as defined in claim 4, in combination with a filling probe, wherein the device is slidably engageable by the filling probe. 6. A method of aseptically receiving fluid into and passing fluid out of a device, the method comprising: engaging a filling probe in fluid communication with a fluid source with a device, wherein said device comprises a sterile chamber having a normally sealed inlet at one end thereof defined by a valve through which fluid enters the chamber, and an outlet for passing fluid out of the chamber; wherein the valve comprises a valve seat and a valve member and is configured to be moveable between (i) a normally closed position, wherein the valve member is sealingly engaged with the valve seat, and, in turn, forms a fluid-tight seal therebetween, and (ii) an open position, wherein the valve member is disengaged from the valve seat, and, in turn, permits fluid at the inlet to flow through the valve and into the chamber but prevents ingress through the valve of germs, bacteria or unwanted substances; wherein the engaging step includes placing the filling probe in fluid communication with the inlet;moving the valve from the normally closed position to the open position;introducing fluid from the source of fluid from the filling probe, through the valve, and into the chamber of the device;passing said fluid from the chamber through the outlet thereof; andmaintaining fluid within the chamber sealed with respect to ambient atmosphere during said passing step. 7. A method as defined in claim 6, wherein the engaging step comprises slidably engaging the filling probe with the device. 8. A method as defined in claim 6, further comprising the step of disengaging the device and filling probe from each other. 9. A method as defined in claim 6, wherein the valve member comprises an elastomeric material. 10. A method as defined in claim 6, wherein the device further comprises a spring connected to the valve and having an opening therethrough, and the introducing step further comprises introducing fluid through the opening in the spring. 11. A method as defined in claim 10, wherein the opening is in fluid communication with the valve. 12. A device for aseptically receiving fluid therein and passing fluid out of the device comprising: a sterile chamber having a normally sealed inlet at one end thereof defined by a valve through which fluid enters the chamber, and an outlet for passing fluid out of the chamber,wherein the valve comprises a valve seat and a valve member and is configured to be moveable between (i) a normally closed position, wherein the valve member is sealingly engaged with the valve seat, and, in turn, forms a fluid-tight seal therebetween, and (ii) an open position, wherein the valve member is disengaged from the valve seat, and, in turn, permits fluid at the inlet to flow through the valve and into the chamber; anda spring connected to the valve having an opening therethrough configured to permit said fluid to flow through the opening during filling of the chamber. 13. A device as define in claim 12, wherein the valve member comprises an elastomeric material. 14. A device as defined in claim 12, wherein the valve further comprises at least one fluid-flow aperture for the passage of fluid from the inlet therethrough and into the chamber when the valve is in the open position. 15. A device as defined in claim 12, wherein the device is slidably engageable by a filling probe in fluid communication with a source of fluid and adapted to move the valve from the normally closed position to the open position, and, in turn, introduce fluid at the inlet, through the valve and into the chamber. 16. A device as defined in claim 15, in combination with a filling probe, wherein the device is slidably engageable by the filling probe. 17. A device as defined in claim 12, wherein the opening is in fluid communication with the valve. 18. A device as defined in claim 12, wherein fluid within the chamber is maintained sealed with respect to ambient atmosphere during passing of said fluid through the outlet of the device. 19. A device as defined in claim 1, wherein the valve seat is more rigid than the valve member. 20. A method as defined in claim 6, wherein the valve seat is more rigid than the valve member. 21. A device as defined in claim 1, wherein the device further comprises an axially-compressible spring connected to the valve. 22. A method as defined in claim 6, wherein the device further comprises an axially-compressible spring connected to the valve. 23. A device as defined in claim 1, in combination with a further device including a cannula or probe adapted to engage the device or be coupled in fluid communication with the valve. 24. A devices as defined in claim 23, whereby when fluid is introduced through the cannula or probe, fluid flows through the valve and into the chamber. 25. A device as defined in claim 23, wherein the cannula or probe is configured to engage the device adjacent to an inlet to the valve. 26. A method as defined in claim 10, wherein the spring comprises a dome spring. 27. A device as define in claim 12, wherein the spring comprises a dome spring.
