VALVE ASSEMBLY FOR POWDER DISPENSER

摘要

A powder dispenser (10) comprising a powder container (11) having an opening (12) in a lower end (13) thereof, a powder receptacle (20) having a flange (22), and a flow control assembly having pivotable flow control arms (26) biased against each other, pivotable activation arms (28) biased towards each other, and connecting members (31) for connecting the flow control arms (26) to the activation arms (28) for concomitant movement, wherein the receptacle flange (22) is operable to engage the activation arms (28) to pivot the activation arms (28) away from each other and thereby pivot the flow control arms (26) away from each other so that powder is allowed to flow through the flow control assembly into the receptacle (20). The dispenser (10) may further comprise an agitator (35) that is operable to agitate the powder in the container (11) when the flow control arms (26) are pivoting towards or away from each other.
