ABSTRACT:
An apparatus and process for shaping multiple expended thermoplastic containers, specifically plastic bottles into rock shapes by placing the expended plastic bottles into a partitioned tray which is placed onto the top surface of a lift table secured to a jack mounted on a four-wheel dolly and heating the plastic bottles to a malleable state. The lift table is then rolled into an open face shaping chamber that has angle irons secured on the interior sides near the top of the chamber to support and allow a removable tray to which real rocks of different shapes and sizes have been secured to be slid into the chamber with the rocks pointing downward from the tray into the chamber. The lift table with the heated malleable bottles is jacked upward toward and into the real rocks until the bottles take the shapes of the real rocks. Then the table is lowered and wheeled out of the shaping chamber. The number of partitions in the bottle tray corresponds to the number of rocks in the rock tray and the trays can be removed and changed to accommodate bottles and rocks and different numbers and sizes. The apparatus allows for multiple bottles to be processed at one time.
