The invention provides a batch feed type food waste disposer having a unitized assembly of its hopper and hopper flange, with these two elements shaped so as to be formed from a non-corrosive sheet material such as stainless steel and rolled together or welded at their abutting edges to form a water-tight joint which includes, at the periphery of the joint, a cooperating opening for the stopper-switch that actuates the food waste disposer to an active comminuting condition.
