Patent ID: 7451901

Claim:
A metering and dispensing device for free flowing materials, comprising: a volume body having first and second ends, and a volumetric channel extending therethrough, said second end being adapted for attachment to a container; a measuring partition operatively associated with the second end of the volume body, said measuring partition including a measuring opening, and a barrier lip portion extending from one end of said measuring opening into said volumetric channel, said measuring opening being 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 for setting a predetermined volume of material to be dispensed; a feed partition operatively associated with the measuring partition, said feed partition including a feed opening selectively movable from a closed position to an open position relative to the measuring opening, for receiving material for passage into the preset volume of said volumetric channel; a discharge partition operatively associated with the first end of the volume body, said discharge partition including a discharge opening selectively movable from a closed position to an open position relative to the volumetric channel, for passage of material from said volumetric channel through said discharge opening; a cylindrical housing or case including an upper case member, and a lower case member, said upper and lower case members being adapted for mating securely together, with said upper case member being rotatable relative to said lower case member; a top portion of said upper case member being configured to provide said discharge partition; said volume body, measuring partition, and feed partition being successively stacked in the order given between said top portion of said upper case member and a bottom portion of said lower case member, respectively; a volume body antirotation mechanism including interlocking portions of said volume body and interior wall portions of said lower case member; and first and second tabs extending from said feed partition and said measuring partition, respectively, through first and second radial slots, respectively, in said lower case member.
