Abstract
A squeezable dispenser having main flexible outer container closed off by a top and an inner collapsible flexible fluid containing bladder. A one-way flow valve is provided between the outer container and the inner bladder 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 vent and normally closes off the same when the dispenser is squeezed to dispense liquid in the bladder out through the valve.
