Abstract
An apparatus for dispensing single homogeneous units upon rotation of the apparatus comprising a generally circular walled container having a bottom for holding the singular homogeneous units. A discharge area located distally from the bottom for receiving the single homogeneous units and for discharging them upon rotation of the apparatus. A helical spiraled rib member located on the generally circular walled container extending from the bottom of the container and along the circular walls of the container for creating during rotation a continuously variable inclined surface along the helical spiraled rib member and the circular walls of the container for advancing single homogeneous units along said helical spiralled rib member and the generally circular walls of the container until a single homogeneous unit reaches the discharge area for discharge from the container. The helical spiraled rib member has a helix depth from the circular wall of the container sufficient for advancing only a single homogeneous unit along the helical spiraled rib member and the generally circular wall of the container until a single homogeneous unit reaches the discharge area. The helical spiralled rib member has a helix angle sufficient relative to the length of the generally circular walled container from the bottom to the discharge area for creating during rotation a sufficient inclined surface for advancing single homogeneous units to the discharge area. Further, this invention provides removable caps which are used to seal these containers from the ambient environment when not being used for dispensing of single homogeneous units.
