ABSTRACT:
A particulate matter dispenser is operated by a push button to move a sliding clamp through a linkage into and out of engagement with an elastic tube at the bottom of a reservoir holding the particulate matter. Coil springs normally bias the sliding clamp into engagement with a fixed clamp or the like so as to hold the tube in a closed position to prevent discharge of material.
