ABSTRACT:
A method and apparatus for assembling a thin film beam spring vent valve is provided. The thin film beam spring vent valve is provided in a squeeze pump package. The package includes an outer resilient bottle and a flexible bag with a relatively rigid fitment. The outer resilient bottle is provided with a substantially cylindrical internal surface portion and an aperture to enable fluid communication between the interior and the exterior of the outer bottle. The valve includes a thin film beam spring located adjacent the aperture 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. An automated mechanism is provided for cutting and grasping (e.g., utilizing a vacuum mandrel) a beam spring comprising a predetermined length of a band of flexible material. The vacuum mandrel is then inserted into the bottle adjacent the substantially cylindrical internal portion such that upon release of the vacuum the beam spring expands against the substantially cylindrical internal surface of the bottle such that central portion of the beam spring is adjacent the aperture. A method and apparatus for inserting the flexible bag into the outer bottle of the squeeze pump package is also provided.
