A closed granular chemical handling system comprising a dispensing valve and a receiving valve. The dispensing valve and the receiving valve are automatically opened when the valves are coupled together, and are automatically closed when the valves are uncoupled from one another. The valves are configured so that the receiving valve always is the first to open and the last to close. The valves are driven together by a camming structure having a neutral portion that acts as a delay between the opening and closing of both valves so as to allow granular material to flow from between the valves through the receiving valve.

Closed granular chemical handling system

The present invention provides a container for use in a closed application system for liquid or granular agricultural treatment agents. The agent is introduced into the container through an inlet opening on the upper surface of the container. Thereafter, a valve is removably mounted to seal the inlet opening and prevent inadvertant discharge of the liquid from the container. Hand grips are provided to manipulate the container, and the container is configured so that it nested or stacked on other similar containers having valves extending from the respective inlet openings when the containers are transported in an upright position. The handgrips are also employed to mount the containers in an inverted position in agricultural application equipment. Empty containers may be transported back to a supply station for refilling with the valves of the respective containers still mounted in the inlet openings to seal the openings and prevent inadvertant discharge or leakage of residue liquid or granular treatment agents still remaining in the containers. The reusable containers enable the agricultural treatment agents to be transported between a supply station and application equipment without any direct exposure to the user.
