Valve for use in a container which employs pressure to dispense product
Abstract:
A valve for a pressurized dispensing container has a resilient annular grommet that surrounds a valve stem. The grommet has a lower segment which engages an elongate valve stem opening with a slight interference fit to provide user controllable metering of the product being dispensed. A recess in the lower surface of the grommet contains the stem button from the closed state to the fully open state to provide stability for the stem. The upper portion of the grommet has a restoring boot to assure that the valve is returned to its closed state once manual force is removed from the valve. A boot flange and stem recess engagement together with other dimensional relationships assures that the boot provide the required restoring force throughout the dispensing of product.
