ABSTRACT:
A tilt action valve assembly is disclosed which has a cup for mounting to a container, the cup holding a grommet seal which surrounds a valve stem. The grommet seal has a lower portion which surrounds a lower portion of the stem and which provides a seal for engagement with a valve stem seat. An upper portion of the grommet seal is bowed and thin walled to absorb stem displacement above the cup, thus limiting seal displacement below the cup. A lip locks the upper portion to the stem to assure co-movement therewith. Utilizing the valve assembly provides for a maximized opening between the stem seat and seal to optimize the flow of fluid through the stem.
