<p>This invention relates to an electric device comprising a metallic hollow cylinder 10 cm in diameter and 10 cm in height, a double resistance that is rotating in the cylinder, a thermostat that controls the temperature, a thermostat tube, which joins the resistance with the thermostat, a switch, an indicating lamp, an external cylindrical cover around the cylinder as well as a metallic body in which all the above parts are adapted. The cylinder is heated by supplying electric power to the resistance and when the temperature reaches 60° to 70 °C, the thermostat breaks the power supply, so when the lower part of the plastic bottle is put into the warm cylinder and been pushed downwards manually, in 3 seconds it is melted and reduced, therefore the bottles do not occupy much space in the refuse places and they are easily stored and collected for recycling purposes.</p> |
