Abstract:
A trigger sprayer has a one piece valve member that includes both an inlet valve element and an outlet valve element. The one piece valve member replaces the separate liquid inlet valve and liquid outlet valve of a conventional trigger sprayer, and thereby provides a more simplified construction for the trigger sprayer and a fewer number of component parts in the trigger sprayer.
