Patent ID: 8870032

Claim:
A dispensing device for dispensing dry granular material, the dispensing device comprising: an inner tube; an outer tube, the inner tube slidably positioned within at least a portion of the outer tube so that the inner tube is slidable within the outer tube; a removable material reservoir connectable to the inner tube configured to allow a flow of material downward into the inner tube; a cylinder rigidly connected to the outer tube and configured such that an end of the inner tube distal from the removable material reservoir is movable within the cylinder as the inner tube is slid within the outer tube; a valve located at a bottom end of the cylinder that prohibits flow of material out of the cylinder under gravity alone; at least one stop configured to restrict sliding movement of the inner tube within the outer tube so that the end of the inner tube distal from the removable material reservoir moves a predetermined length within the cylinder; a piston ring secured to the inner tube, the piston ring being proximate to the end of the inner tube distal from the removable material reservoir, the piston ring configured to fit an inside diameter of the cylinder such that, as the end of the inner tube is slid upward within the cylinder, material from the removable material reservoir in the inner tube flows into the cylinder and, as the end of the inner tube is slid downward, the piston ring pushes against the material within the cylinder to create a pressure to open the valve.
