Abstract
A device for trapping flatware in food waste prior to entry into a trash container includes a housing positioned onto the trash container having a downwardly sloping chute, an electronic metal detector disposed in the housing, and a mechanically-operated pivoting door that guards the lower opening of the chute. A spring-loaded mechanical linkage closes the door upon being released by an actuator, that is signaled by the metal detector as to when flatware is present. The use of a spring-loaded mechanism to operate the pivoting door minimizes power requirements and is lightweight, as compared to a drive motor or other machines of the prior art.
