Abstract

A hydraulically actuated knife punctures a container of chemicals, dispenses them to a storage reservoir and simultaneously therewith dilutes and mixes the chemicals with water. Next, a spray directed along the knife automatically washes the interior of the container to insure that all of the chemicals are removed. Once the container is punctured, the contents of the container spill down over and about the knife and into the storage reservoir. When the hydraulic pressure is released, the knife, which is springloaded when actuated, returns to its original position.
