Abstract
A cleaning assembly is provided for a foam dispensing apparatus which intermittently supplies a solvent to the discharge port of the dispensing apparatus for removal of accumulations of dispensed foam therefrom. The cleaning assembly is constructed from a body having a wall forming an opening extending therethrough in communication with the discharge port of the dispensing apparatus. At least one passageway is formed in the body for discharging the solvent from a supply thereof onto the face of the dispensing apparatus surrounding the discharge port.
Claims10
A cleaning assembly for use with a fluid dispensing apparatus comprising dispensing means positioned adjacent the face of a dispensing apparatus, said dispensing apparatus having a port in said face in communication with a chamber in said dispensing apparatus from which a first fluid is discharged, said dispensing means comprising a body having a surface forming an opening extending therethrough in alignment with said port of said dispensing apparatus and a groove formed in said surface adjacent said port to provide a reservoir within said opening for retaining a quantity of a second fluid discharged from said dispensing means, said dispensing means discharging said second fluid onto said face within said opening for preventing said first fluid discharged from said chamber from accumulating on said face at said port.
A cleaning assembly for use with a foam dispensing apparatus comprising, dispensing means for discharging a solvent secured adjacent the face of a foam dispensing apparatus, said dispensing apparatus having a port in said face in communication with a mixing chamber in said dispensing apparatus from which a foam formed by the mixing of a plurality of fluids in said mixing chamber is discharged, said dispensing means comprising a body having a wall forming an opening extending therethrough in alignment with said port of said dispensing apparatus, a plurality of passageways formed in said body for discharging a solvent onto said face of said dispensing apparatus, and a groove formed in said body at least partially circumscribing said opening and in fluid communication with each of said plurality of passageways, said groove adapted for supplying said solvent through each of said passageways and onto said face of said dispensing apparatus within said opening for preventing said foam discharged from said mixing chamber from accumulating on said face at said port.
A cleaning system for use with a fluid dispensing apparatus comprising, a dispensing apparatus having a chamber from which a first fluid is discharged, a cleaning assembly positioned adjacent a discharge port of said dispensing apparatus through which said first fluid is discharged from said chamber, said cleaning assembly comprising a body having an opening iin alignment with said discharge port of said dispensing apparatus, and dispensing means within said body for discharging a second fluid onto said discharge port for preventing said first fluid discharged from said chamber from accumulating thereon, said dispensing means comprising a plurality of passageways formed in said body for discharging said second fluid therethrough and onto said discharge port of said dispensing apparatus and a groove formed in said body in fluid communication with each of said passageways at least partially circumscribing said opening for supply said second fluid to each of said passageways.
