Claim 1
Independent Claim
161 words
A device for dispensing fluid on demand, which comprises: (a) an elongated housing for containing an end portion of a flexible fluid-conveying tube, and having a first opening at one end for receiving the tube, and a second opening at the opposite end for discharging the fluid; (b) a flexible pinch clamp fitted within the housing through which a flexible tube may pass and be clamped shut thereby, wherein said pinch clamp possesses clamping edges biased toward a closed position upon each other; (c) lever means outside of the housing, pivotally mounted through the sides thereof; (d) at least one tab between the clamping edges of the pinch clamp, said tab connected to, or part of, said lever means; said device adapted such that application of pressure on the lever means causing movement of same toward the housing pivots the tab and forces the clamping edges apart, and upon release of the pressure, the clamping edges close back upon each other.
