Abstract
A liquid storage and delivery apparatus utilizing a canister or container which holds a flexible diaphragm supported by a frame. The frame biases the flexible diaphragm against the inner wall of the container and allows expansion and contraction of the diaphragm in certain direction. A seal creates a substantially air tight space within the canister to allow directed pressurized gas to motivate the movement of the diaphragm within the canister. A lid or fitting supports a collapsible bag carrying a liquid within a second space within the canister such that movement of the flexible diaphragm against the collapsible bag forces or squeezes liquid from the same for use.
