ABSTRACT:
A fluid dispensing unit includes a hollow support with a reservoir or container located within the support. The container has a one-way valve at its outlet for dispensing fluid while preventing any flow of contaminants back into the container. As fluid is dispensed, the container can be collapsed to assure complete evacuation of the fluid.
