Solid block chemical dispenser for cleaning systems
First Claim
1. A solid, water soluble rinse aid contained in a vessel for insertion into and dilution within a dispenser having a support for the rinse aid, said article comprising:
- (a) a three-dimensional, solid, orthogonal block of rinse aid comprising;
(i) 20 to 40% by weight polyakylene glycol hardening agent having a M.W. of about 8000;
(ii) 10 to 30% by weight anionic hydrotrope and(iii) 40 to 60% of an nonionic agent; and
(b) an orthongonal vessel having an open face and a leading edge, the vessel surrounding and in contact with the block of rinse aid on all but one surface thereof, the cross-sectional area of the open face sufficient to allow passage of the entire block of rinse aid therethrough, wherein prior to placing the solid, orthogonal block of rinse aid into the dispenser, the block of rinse aid can be separated from the vessel and inserted into the dispenser and retainably held by the support at a constant distance above the spray nozzle.

Abstract
A solid block chemical dispenser for cleaning systems. A substantially horizontal support screen within a housing retainably supports a solid block of wash chemical thereabove. The support screen divides the housing into an upper cylindrical storage portion and a lower funnel shaped collector portion. A spray forming nozzle is mounted within the collector portion below the generally horizontal screen for directing a spray of water at substantially the entire downwardly facing surface of the wash chemical block supportably retained above the support screen. The dissolved wash chemical passes through the support screen, is collected by the collector portion of the housing, and directed to its utilization point. Spray control means, either manual or electronic, control the spray of water through the nozzle in response to a control signal. The dispenser is configured for mounting to a vertical surface and is loaded through an upper access port normally closed by a door. A safety switch prevents the spray of water from the nozzle whenever the door is open.
