Abstract
A squeezable dispenser having a main flexible outer container closed off by a top having an opening therein and an inner collapsible flexible fluid containing bladder. A one-way flow valve is mounted in the top normally closing off the opening in the top to prevent the contents of the bladder from contamination from external sources. A vent in the top provides fluid communication between the interior of the container and the exterior thereof. A sealing member overlies the valve and normally closes off the same. The dispenser can be squeezed to dispense liquid in the bladder out through the valve.
