Abstract
A two piece dispenser closure, comprising a housing and an interior valve member, is molded of elastomeric plastic material for snap-on mounting on the delivery end of a tubular spout of the flexible plastic container of a liquid in bag-in-a-box packaging. The housing has a valve seat formed with an opening and a forward extension formed as a hollow compressible push button. The interior valve member has a valve body with a forward portion extending into the push button. The valve body is mounted on a normally forwardly convex annular diaphragm which retains the valve body in a seated, closed position in the housing valve seat. The diaphragm is formed with openings and is resiliently deformable to an invaginated configuration when an inward force is applied to the valve body forward portion through the push button to unseat the valve body whereby liquid flows from the tubular spout through the diaphragm openings, between the valve body and valve seat and is dispensed through the valve seat opening. Upon release of the push button, the latter and diaphragm return to normal valve closing position. In a three piece construction, the valve member has a sleeve engaging the interior surface of the tubular spout which mounts a cap in stopper fashion or a bonded puncturable disc as a seal for the inlet end of the tubular spout, the cap and disc being gas impermeable.
