Abstract
A rotary hand grater has a housing which defines a hopper communicating with an open-ended cylindrical grating chamber in which a grating drum rotates for grating the contents of the hopper. The chamber is closed at one end by handle structure for rotating the grating drum and at the other end by a removable cap. A press plate is movable into and out of the hopper for pressing food against the grating tube. A flexible and resilient seal is clamped between the press plate and a backing surface on a plunger arm for sealing engagement with the hopper side walls and cooperation with the handle structure and the cap to seal the hopper and the chamber.
