ABSTRACT:
A receiving chamber is provided for receiving and enclosing a container of chemical such as an insecticide. While the container is in the chamber, a punch member perforates through the top and bottom of the container to permit the insecticide therein to transfer out from the bottom of the chamber to a main tank of water for mixing therewith. The resulting mixture is then passed to suitable spray apparatus for spraying the insecticide in agricultural operations. A plunger member coaxially surrounds the punch member and extends through the top of the chamber and can be lowered to crush the container after its contents have been emptied into the main water tank. In addition, the punch member includes an internal passage for passing flushing water into the container prior to crushing of the same so that it is cleaned out. The entire system is closed so that there is no risk of operators becoming contaminated by the insecticide chemical.
