Abstract: A pellet dispenser has an egg-shaped housing containing a generally oval diaphragm (24) separating an upper pellet reservoir portion (12) from a lower discharge portion (14) having a discharge opening (8). Lateral pressure can be applied to the diaphragm (24) by a button (20) in the side of the housing to cause the diaphragm (24) to bow. The diaphragm (24) has a central aperture (32) and carries on opposite sides of the aperture a pair of half cylindrical arms (4, 36) defining a channel (38) from the aperture (32) to the opening (8). A pair of mating doors (10) closing the opening (8) are carried at the distal ends of the arms (34, 36). When the diaphragm (24) is squeezed the distal ends of the arms (34, 36) separate to open the doors (10). A pair of rods (42) are attached to the diaphragm (24) only at their opposite ends.
