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.

Claims

1. A dispenser for safely dispensing solid block chemical compositions contained in jars with an orifice for exposing at least one surface of a solid block, comprising:

a housing defining a substantially enclosed inner cavity;

said housing including door means rotatably hinged to said housing for providing access to said cavity for loading and unloading solid block chemical jars, said door means having a range of movement including a closed position in which said cavity is substantially enclosed and an open position in which jars can be loaded and unloaded;

nozzle means extending into said cavity for directing a pressurized spray of liquid vertically upwards;

discharge means mounted in the bottom of said housing to receive liquid from said cavity and to direct the liquid out of said cavity;

jar supporting means in said housing for holding a solid block chemical jar with the jar'"'"'s orifice facing downward; and

spray blocking means coupled to said door means so that when said door means is rotated from said closed position toward said open position, said spray blocking means moves in front of said nozzle means and substantially prevents liquid emanating from said nozzle means from spraying through the opening in said cavity created by opening said door means.

2. The dispenser of claim 1, wherein

said spray blocking means is a flat plate rigidly mounted to said door means.

3. The dispenser of claim 1, wherein

said jar supporting means includes an aperture of a fixed size so that a jar with a neck narrower than said aperture and a main body wider than said aperture can be loaded into said dispenser by placing the jar on said jar supporting means with the jar'"'"'s neck extending through said aperture.

4. The dispenser of claim 1, further including

a grate overlying said discharge means which substantially prevents chunks of solid block chemical which fall from a jar from clogging or going through said discharge means undissolved.

5. A dispenser for safely dispensing chemical compositions contained in jars having a main body and a neck with an orifice at the end thereof, comprising:

a housing defining a substantially enclosed inner cavity;

said housing including

a base configured for fixed mounting to a solid surface; and

door means rotatably hinged to said base for providing access to said cavity for loading and unloading jars of chemicals, said door means having a range of movement including a closed position in which said cavity is substantially enclosed and an open position in which jars can be loaded and unloaded;

nozzle means mounted to extend into said cavity for directing a pressurized spray of liquid vertically upwards;

discharge means mounted in the bottom of said housing to receive liquid from said cavity and to direct the liquid out of said cavity; and

jar supporting means in said housing for holding a jar with the jar'"'"'s orifice facing downward; and

spray blocking means coupled to said door means so that when said door means is rotated from said closed position toward said open position, said spray blocking means moves in front of said nozzle means and substantially prevents liquid emanating from said nozzle means from spraying through the opening in said cavity created by opening said door means.

6. The dispenser of claim 5,

wherein said dispenser is adapted for use with a jar containing a solid block chemical composition;

said dispenser further including

a grate overlying said discharge means which prevents chunks of solid block chemical which fall from a jar from going through said discharge means until said chunks are at least partially dissolved by the liquid from said nozzle and are thereby reduced to be no larger than a predetermined size.
