Disposal compactor for aerosol cans

A disposal compactor for crushing used aerosol spray cans and the like of the type having a nozzle and an output neck and environmentally safely recovering their residual contents, said compactor comprising:

• vertically upright frame means adapted to be disposed upon a supporting surface for mounting said compactor;
• rigid, telescoping receiver means operationally mounted within said frame means for receiving an inverted can to be processed;
• fluid holding tank means in fluid flow communication with said receiver means for receiving waste fluids ultimately liberated from said can;
• crusher means secured to said frame means for activating said receiver means by first contacting said can and forcibly moving it downwardly against said receiver means and thereafter compressing said receiver means during operation of said compactor, said crusher means comprising:
• a hydraulic cylinder operatively disposed in said frame means above said receiver means, said hydraulic cylinder axially aligned with said receiver means;
• ram means driven by and projecting downwardly from said hydraulic cylinder toward said receiver means;
• and,
• platen means secured to said ram means for engaging a bottom flange of said can to drive it downwardly said platen means comprising a recess for mating with said can;
• and,
• wherein said receiver means comprises:
• tubular, stationary sleeve means for securing said receiver means to said frame means, said sleeve means comprising a top and a bottom;
• tubular cylinder means coaxially, slidably disposed within said sleeve means and reciprocally movable a limited distance therewithin for first receiving a can to be processed, said tubular cylinder means comprising a shoulder portion adapted to mate with an upper flange of said can;
• tubular union means coaxialy, fixedly disposed within said sleeve means at said bottom for limiting travel of said tubular cylinder means, said union means comprising a head and an exhaust pipe integral with said head and extending downwardly through said receiver means, said union head and exhaust pipe defining a bore providing fluid flow communication between said receiver means and said tank means;
• valve means normally occluding said exhaust pipe but displaceable by can contact for opening said exhaust pipe to vent fluids to said fluid holding tank means;
• valve guide means disposed within said union means for mounting said valve means, said valve guide means having a thickness less than said bore for preserving fluid flow communication, said valve guide means comprising upwardly projecting lance means adjacent said valve for puncturing the neck of said can after predetermined movement of said tubular cylinder means downwardly within said sleeve means, and valve return spring means for normally biasing said valve means closed;
• an adjustable, tubular receptacle secured to said valve adjacent said lance for receiving the nozzle of an aerosol can to be processed and for preventing said nozzle from being actuated during can movement;
• and,
• cylinder return spring means for normally biasing said tubular cylinder means upwardly within said sleeve means.
