ABSTRACT:
A metering and dispensing device for free flowing materials includes a volume body having first and second ends, and a volumetric channel extending therethrough. The second end of the volume body is adapted for attachment to the opening of a container holding the free flowing material. The device further includes a measuring partition operatively associated with the second end of the volume body. The measuring partition includes a barrier lip portion extending therefrom into the volumetric channel, and a measuring opening selectively movable from a closed position to an open position relative to the volumetric channel, wherein the selective movement of the measuring opening simultaneously causes the barrier lip portion to vary the volume of the volumetric channel relative to the measuring opening. The device further includes a feed partition proximate the second end of the volume body, operatively associated with the measuring partition, the feed partition including a feed opening selectively movable from a closed position to an open position relative to the measuring opening. The device also includes a discharge partition operatively associated with the first end of the volume body, which includes a discharge opening selectively movable from a closed position to an open position relative to the volumetric channel.
