ABSTRACT:
A thin film beam spring valve is provided for use in a squeeze pump package. The squeeze pump package includes a resilient outer bottle and an inner flexible bag with a rigid fitment. An apertured diptube is utilized to enable substantially all of the product within the bag to be dispensed. The outer bottle of the package has a substantially cylindrical finish which includes an aperture therethrough and an internally extending ledge at its lower end. The thin film beam spring is located above the ledge in a cavity created between the bottle finish and the rigid fitment of the inner bag. The central portion of the beam spring is located adjacent to the aperture of the finish such that the beam spring will seal the aperture upon exposure to a positive dispensing pressure within the bottle. The beam spring will allow air to enter the bottle upon the application of negative pressure within the bottle. A method and apparatus for inserting the beam spring, and a method and apparatus for inserting the bag into the bottle are also provided.
