  • Patent number: 5931397
    Abstract: A device is disclosed for efficiently grating and dispensing blocks of hand soap, comprising a housing and soap grating mechanism. The housing includes a tubular feed tower, a hollow cage and a funnel which collectively define a laterally enclosed passageway through which the soap travels. A grating disc is rotatably mounted in the housing, having an annular rim, a hub and a plurality of spokes connecting the hub and rim so as to define openings through which grated soap may pass. A long, thin, serrated metal band is mounted on the spokes in a continuous spiral between the hub and rim, forming a series of coils which define a planar cutting surface. The band is loosely wound, so that successive coils are spaced apart from each other a sufficient distance to easily permit soap shavings to drop through the space between adjacent coils.
