Abstract
A dispenser for safely dispensing solid block chemical compositions contained in jars. The jars have an orifice for exposing at least one surface of the solid block chemical therein. The dispenser has a housing defining a substantially enclosed inner cavity. A nozzle, mounted to extend into the cavity, directs a pressurized spray of liquid vertically upwards, while a discharge outlet mounted on the bottom of the cavity receives liquid from the cavity and directs the liquid out of the cavity. A jar holder in the housing holds one solid block chemical jar with the jar's orifice facing downward. A door rotatably hinged to the housing provides access to the cavity for loading and unloading solid block chemical jars. The door has a range of movement including a closed position in which the cavity is substantially enclosed and an open position in which the jars can be loaded and unloaded. A spray blocker is coupled to the door so that when the door is rotated from a closed position toward its open position, the spray blocker moves in front of the nozzle and substantially prevents liquid emanating from the nozzle from spraying through the opening in the cavity created by opening the door.
