Abstract: A waste disposer having a food chamber and a motor housing that are rotatably coupled together is provided. A clamp couples the food chamber to the motor housing. When the clamp is closed, the clamp causes an open end of the housing to exert pressure on a flange of the food chamber to form a friction-fit between the housing and food chamber. The open end of the housing exerts enough pressure on the flange to prevent leaks between the housing and food chamber. In an open position, the clamp allows relative rotation between the food chamber and motor housing. When the clamp is open, the pressure that the open end exerts on the flange is released to allow rotation therebetween. The configuration of clamp retains the flange in contact with the open end, to inhibit food particles and other matter from lodging between the flange and open end.
