a valve body;
a valve stem moveably disposed in the valve body, the valve stem having at least one exit hole disposed at a tip of the valve stem; and
a valve stem adapter disposed at the tip of the valve stem and welded thereto, the valve stem adapter including at least one adapter exit hole to allow exit of a dispensible fluid from the valve assembly.
2 . The valve assembly of claim 1 wherein the valve stem adapter includes an open end which is disposed over the tip of the valve stem.
3 . The valve assembly of claim 1 wherein the valve stem adapter includes at least one adapter channel extending from the open end toward an adapter tip.
4 . The valve assembly of claim 1 wherein the valve stem adapter includes one or more adapter exit holes for dispensing the dispensible fluid.
5 . The valve assembly of claim 4 wherein the one or more adapter holes extend through a sidewall of the valve stem adapter.
6 . The valve assembly of claim 5 wherein the one or more adapter holes extend in a substantially radial direction relative to a central axis of the valve stem adapter.
7 . The valve assembly of claim 1 wherein the valve stem adapter is formed from a plastic material.
8 . The valve assembly of claim 1 wherein the valve stem adapter is affixed to the valve stem by ultrasonic welding.
9 . A dispenser for a fluid comprising:
a cannister;
an inner bag for dispensible fluid disposed inside of the cannister; and
a valve assembly extending through the cannister in flow communication with the inner bag, the valve assembly comprising:
a valve body;
a valve stem moveably disposed in the valve body, the valve stem having at least one exit hole disposed at a tip of the valve stem; and
a valve stem adapter disposed at the tip of the valve stem and welded thereto, the valve stem adapter including at least one adapter exit hole to allow exit of a dispensible fluid from the valve assembly.
