ABSTRACT:
A weight alarm device for a trash container having a body with a top surface resiliently connected to a bottom surface, a switch attached to the body and responsive to relative movement between the top surface and the bottom surface, and an alarm electrically connected to the switch for producing a humanly perceivable signal when the relative movement between the top surface and the bottom surface exceeds a predetermined amount. The body has a shape adapted for receipt within the trash container. The top surface and the bottom surface have overlapping sides extending around the periphery of the surfaces. A coil spring is interposed between the top and bottom surfaces. The switch is a contact switch which is movable between a first position and an alarm sounding second position. An abutment member is connected to the bottom surface so as to contact the contact switch upon a movement of the top surface beyond a predetermined amount.
