Abstract
A device for containing and metering a powder-form product has a body member which defines a hopper and a tube which extends from the hopper. The tube has successive portions configured to provide at least one metering chamber and a flow chute which extends to a tube opening for delivering powder-form product from the hopper via the metering chamber. A plug member is connected with a closure member which, in turn, is connected to a connecting member which, in turn, is connected with a housing member positioned in the hopper. A mounting member is affixed with the hopper, a first rotatable lever extends from the mounting member into the hopper, and a second rotatable lever extends from the mounting member outside of the hopper about a same axis as the first lever so that upon rotation of the second lever, the first lever is rotated. The housing member is configured for being engaged by rotation of the first lever, and the closure member and plug are configured and positioned, respectively, to cooperate with the metering chamber and to open and close the tube opening for dispensing metered amounts of powder-form product.
