Abstract
A weed or insect terminating device features a container having a valve port, a heating element, a valve core, and a biasing mechanism forcing the valve core into an extended position. An axial passage in the valve core extends through only a distal end of the valve core. A lateral passage intersects the axial passage and opens radially from the valve core. A proximal seal is provided between the valve core and valve port at a location between a proximal end of the valve core and the opening of the lateral passage. The proximal seal withdraws from sealed contact with the port in a retracted state of the valve core, while a distal seal remains intact. Heated water from the container can be dispensed through the valve port only via the lateral and axial passages of the valve core, and only when made accessible by retraction of the valve core.
