First Claim
1. A device for the controlled delivery of a soapy water liquid concentrate solution to a sink as the sink is filled by a stream of water from a source of fill water, the device comprising:
- a container having a base predeterminately configured so as to allow said container to be placed in a stationary operative position within the sink beneath the source of fill water and in the path of the stream of water;
said container containing a predetermined quantity of water soluble, semi-solid detergent, said detergent comprising a substantially homogeneous, malleable mass of high density, semi-solid detergent, said mass being substantially affixed to an interior surface of said container and having an exposed surface portion within said container, said exposed surface being exposed to said stream of fill water entering said container through said first aperture;
said container having a first aperture defined therethrough in spaced relation to said base, said first aperture being predeterminately sized and oriented such that when said container is in said operative position, the stream of water from the source of fill water enters said container through said first aperture and agitates against said exposed surface and commingles with said semi-solid detergent in the container so as to dissolve a predetermined fractional quantity of the semi-solid detergent in the fill water entering the container and thereby form a soapy water liquid concentrate;
said container having a height defined by the spacing between said base and said first aperture;
said container having defined therethrough a second aperture from which said soapy water concentrate is ejected from the container by increased pressure developed within the container in response to the entry of the stream of fill water into the container through said first aperture, said ejection gradually filling the sink with the ejected soapy water concentrate; and
said container height being selected such that when the sink is filled to a level in excess of the height of said container, said agitation of the fill water within the container substantially ceases and said ejection of soapy water liquid concentrate through said second aperture substantially ceases so that, upon further filling of the sink with water from the fill source, the soapy water concentrate in the sink is diluted to a desired soap concentration level.

Abstract
A device and method for the controlled release of a soapy water concentrate into a sink or basin for providing a sink full of soapy water for institutional pot, pan and dishwashing applications. The device is implemented as a container filled with semi-solid, water-soluble soap concentrate. The container has a base which allows it to freely stand at the bottom of the sink being filled with water. A stream of water from a sink faucet is directed into an inlet aperture on an upper surface of the container. The water enters the inlet aperture, commingling and interacting with the semi-solid soap to dissolve a fractional portion thereof and form a soapy water concentrate solution. The solution is ejected under pressure by the entering water out through a plurality of outlet apertures defined in the container, thereby filling the sink with soapy water concentrate. Water is directed into the inlet aperture until the water level of the sink rises to or above the level of the inlet aperture, whereupon the container may be removed from the sink and plain water is permitted to fill the sink to a desired level, diluting the soapy water concentrate solution to a degree suitable for institutional pot, pan and dishwashing applications. Formation of the soapy water concentrate is self-terminating since, once the water level in the sink rises above the inlet aperture, water is no longer forced under pressure into the inlet aperture and the formation of soapy water concentrate within the container diminishes to a negligible level.

17. A method for the controlled delivery of a soapy water liquid concentrate solution to a sink as the sink is filled by a stream of water from a source of fill water, the method comprising the steps of:
-
(a) positioning a container having a base and containing a predetermined quantity of a water-soluble, substantially homogeneous, malleable mass of high density, semi-solid detergent in a stationary operative position within the sink to be filled With soapy water beneath the source of fill water; (b) directing a stream of fill water from the fill water source toward a first aperture defined in and through said container at a location spaced frown the container base, the spacing between the base and the first aperture defining a height of the container, said first aperture being predeterminately sized and oriented so that when said container is in said operative position, the stream of water from the source of fill water enters the container through the first aperture and agitates against and commingles with the semi-solid detergent so as to dissolve a predetermined fractional quantity of the semi-solid detergent in the fill water entering the container and thereby form a soapy water liquid concentrate; (c) continuing to direct the stream of fill water toward and through the first aperture so as to cause the ejection of the soapy water concentrate from a second aperture defined in the container and through which the soapy water concentrate is ejected from the container by increased pressure developed in the container as a result of the entry of fill water through said first aperture so that said ejection gradually fills the sink with the ejected soapy water liquid concentrate; (d) allowing the sink to fill with the soapy water concentrate from the container to a level in excess of the height of said container such that agitation of the fill water within the container substantially ceases and said ejection of soapy water liquid concentrate through said second aperture substantially ceases; and (e) predeterminately diluting the soapy water concentrate in the sink to a desired working dilution by further filling the sink beyond the level of step (d) to a working water level with water from the fill source. - View Dependent Claims (18, 19)
