Abstract
This invention is a collapsible flexible pouch that fits into a rigid bottle that is connected to a pump such that the pouch collapses while the bottle remains rigid as the contents of the pouch are pumped out. The pouch has a rigid upper part that serves as a seat for the collapsing pouch, the pouch also having one and only one contraction forming an annular concertina that seats on the upper rigid part of the collapsible pouch which collectively prevents blocking and clogging of the exit opening very effectively. An air inlet is provided in the rigid bottle to prevent a vacuum from forming around the collapsing pouch as its contents are dispensed.
