Abstract
A powder-dispensing brush head comprises a body having first and second angularly related faces, a plurality of bristles distributed over the first face and a passageway extending through the body from an inlet at the second face towards an outlet at the first face of the body. The passageway, as considered from its inlet to its outlet is unidirectional and inclined towards the first face, and the body is provided with at least one coupling formation for connection of the brush head to a flexible-walled container with the mouth of the latter in registry with the inlet. The passageway is smoothly tapered over a major part of its length from a larger diameter adjacent its inlet to a smaller diameter adjacent its outlet.
Claims7
A powder-dispensing brush head comprising a body having first and second angularly related faces, a plurality of relatively stiff bristles distributed over a sheet connected with said first face, a single powder outlet in said first face and said sheet, a powder inlet in said second face, and at least one coupling formation connecting the brush head to a flexible-walled powder container with the mouth of the latter in registry with said inlet, wherein the improvement comprises a passageway leading from said inlet and having only one outlet orifice coinciding with the outlet in said first face, said passageway:
- a. being unidirectional and extending in a straight line from said inlet to said outlet orifice,
- b. extending at an acute angle to said first face, and
- c. being smoothly tapered over a major part of its length from a larger diameter adjacent said inlet to a smaller diameter adjacent said outlet orifice, whereby powder flows smoothly from said inlet to said outlet orifice without clogging.
