ABSTRACT:
A toy apparatus and method for making vacuum formed articles wherein a thin sheet of plastic is secured on a mold in a first position the mold is moved to a second position adjacent a heater for heating and softening the plastic sheet and a vacuum is applied to the mold and heated sheet either while it is in the second position or after it is moved back to its original first position. The apparatus includes a transparent safety cover and a shuttle lever which in combination reduce the possibility of a child operator of this toy from burning his or her fingers. The safety cover, if open, bars movement of the mold to the heater and bars entry of fingers toward the heater, and if closed, bars touching the mold, plastic sheet or heater. Following closure of the safety cover a first lever may be moved to drive the mold to the heater and a second lever may be moved to actuate the vacuum pump. The safety cover cannot be re-opened until the shuttle lever is returned to its start position.
