ABSTRACT:
A dispensing system for particulate matter is disclosed comprising a primary receptacle, a guide member, a sliding tube, and a valve member. The primary receptacle receives particulate material and has an open end, an opposed bottom, and a surrounding wall. The guide member is fixed to the bottom of the primary receptacle and defines a supporting aperture and an associated axis approximately normal to the bottom. The sliding tube is slidably disposed within the supporting aperture of the guide member. The sliding tube is characterized by a longitudinal feed passage therethrough substantially parallel to the axis. The sliding tube has a travel limit restricting its axial translation relative to the guide member between a first position and a second position. The valve member is mounted inside the primary receptacle over the guide member. The valve member has bristles disposed over and operably blocking the supporting aperture. The bristles are displaced radially outward from the axis by the sliding tube as the sliding tube is moved from the first position to the second position.
