Volume metering dispenser

1. A fluid dispensing assembly comprising:

a body having a fluid cavity therein, the body comprising a body wall, the body wall having at least a portion thereof that is transparent or translucent, thereby permitting the operator to see the level of fluid within at least a portion of the fluid cavity;

a valve disposed within the body, the valve comprising a seal, the seal selectively engaged to the body; and

a resilient member, the resilient member being elastically deformable; wherein the valve is attached to the resilient member with the resilient member being attached to an exterior of said body;

wherein the fluid cavity defines a first chamber and a second chamber, the first and second chambers being in fluid communication when the fluid dispensing assembly is in the closed configuration, and

wherein the second chamber is isolated from the first chamber when the fluid dispensing assembly is in the flow configuration and both the first chamber and second chamber are opened to dispense fluid when said valve is opened.

2. The fluid dispensing assembly of claim 1 , wherein the valve further comprises a stem, at least a portion of the stem engaged to the resilient member.

3. The fluid dispensing assembly of claim 2 , wherein the stem has a first opening therein.

4. The fluid dispensing assembly of claim 3 , wherein the stem has a second opening therein, the second opening longitudinally offset from the first opening along the length of the stem.

5. The fluid dispensing assembly of claim 2 , wherein the stem comprises at least one guide member.

6. The fluid dispensing assembly of claim 5 , wherein the body comprises at least one guide channel, the at least one guide member slidable within the at least one guide channel.

7. The fluid dispensing assembly of claim 2 , wherein the stem comprises a first recessed portion and a second recessed portion, the second recessed portion being longitudinally offset from the first recessed portion along the length of the stem.

8. The fluid dispensing assembly of claim 1 , wherein the resilient member comprises a dome-shaped push button.

9. The fluid dispensing assembly of claim 8 , wherein the dome-shaped push button has an interior and an exterior, the interior having a protruding member extending therefrom.

10. The fluid dispensing assembly of claim 1 having a closed configuration and a flow configuration.

11. The fluid dispensing assembly of claim 1 , wherein the second chamber is vented when the fluid dispensing assembly is in the flow configuration.

12. The fluid dispensing assembly of claim 11 , wherein the body further defines a third chamber, the second chamber venting through the third chamber when the fluid dispensing assembly is in the flow configuration.

13. The fluid dispensing assembly of claim 12 , wherein the second chamber is isolated from the third chamber when the fluid dispensing assembly is in the closed configuration.

14. A fluid dispensing assembly having a flow configuration and a closed configuration, the fluid dispensing assembly comprising:

a body having a fluid cavity therein, the body has a first chamber, a second chamber, and a body wall, the body wall extending along at least a portion of the second chamber, the body wall extending along at least a portion of the second chamber having at least a portion thereof that is transparent or translucent such that the level of fluid within the second chamber is visible from outside of the second chamber;

a valve disposed within the body, the valve isolating the first chamber from the second chamber when the assembly is in the flow configuration and allowing fluid within the first chamber and second chamber to flow out of said valve when in the flow configuration, the valve comprising a seal and a stem, the seal selectively engaged to the body; and

a resilient member, the resilient member being elastically deformable; wherein the valve is attached to a portion of the stem;

wherein, in the closed configuration, the first and second chambers are in fluid communication with one another;

wherein the valve has a first opening extending therethrough, and wherein in the closed configuration the first opening allowing for fluid communication between the first and second chambers; and

wherein the body further has a third chamber, the second chamber being vented through the third chamber when the assembly is in the flow configuration.

15. The fluid dispensing assembly of claim 14 , wherein the second chamber is vented through the first chamber when the assembly is in the closed configuration.
