US 5,259,557 A · Solution proportioner and dispensing system

Abstract

A system for proportioning and dispensing concentrated liquid products is disclosed. The components of the system's first embodiment are mounted upon a cart (12). A concentrate solution tube (14) is interconnected to a dilution assembly (61) containing an aspirator (26). A water supply assembly (69), containing a valve (75) and backflow preventer (74), is connected to the aspirator assembly (26) when dilution of the concentrated product (13) is desired. A discharge tube (68) carries the diluted product from the aspirator assembly (26) to a container (60). The system's second embodiment has a spray gun assembly (150) containing an aspirator (167), a valve (166), and preferably though not necessarily, a backflow preventer (165). The concentrate pickup tube (114) attaches to the spray gun assembly (150) with a releasable connector (170). The spray gun assembly has a rigid delivery tube (153) for dispensing to large containers (160), and a nozzle tip (180) for attachment to an inlet port (119) of a jug (111). Also disclosed is a method for dispensing and handling solutions.

Dependent claims

A system for diluting and dispensing a chemical, comprising:

(a) gun means attached to and in fluid communication with a diluent supply hose which carries a diluent, said gun means including an aspirator, a backflow preventer, and a valve for controlling flow of diluent, said aspirator, backflow preventer and valve being located within said gun means, said valve being controlled by an actuator operably attached to said gun means, said gun means further including a releasable quick connector means for connecting and disconnecting a concentrate supply tube;
and
(b) at least two concentrate containers, each containing a concentrated chemical, wherein said concentrate containers are positioned on a support means, one end of a concentrate supply tube extending into each of said concentrate containers, wherein said support means includes a holder sized and configured to accommodate said gun means when said gun means is in a non-use position;
and wherein when one of said concentrate supply tubes is connected to said gun means and said actuator opens said valve, the concentrated chemical within the concentrate container which is fluidly connected to said gun means flows through said aspirator into said gun means and is dispensed therefrom in diluted form.

A system for diluting and dispensing a chemical, comprising:

(a) a plurality of concentrate storage containers for storing concentrated chemicals, each of said storage containers having a pickup tube extending therefrom, said concentrate storage containers being supported upon shelf means;
(b) dispensing gun means having a first water inlet end and a second outlet end, said dispensing gun means including a valve for controlling water flow, said valve being controlled by an actuator operably attached to said dispensing gun means, said dispensing gun means further including:
(i) an aspirator within said dispensing gun means,
(ii) a releasable connector means for releasably connecting to one of said pickup tubes,
(iii) a delivery tube, and
(iv) a gun nozzle,
said delivery tube being connected to said gun nozzle, and said shelf means including mounting means for releasably mounting said dispensing gun means when said dispensing gun means is in a non-use position;
(c) a water hose connected to said first water inlet end;
(d) metering means in at least one of said pickup tubes;
and
(e) a drum for storing diluted chemical, wherein when one of said pickup tubes is connected to said dispensing gun means and said actuator opens said valve, the concentrated chemical within the concentrate storage container which is fluidly connected to said dispensing gun means flows through said aspirator into said dispensing gun means forming a diluted chemical, and said delivery tube being insertable within said drum for dispensing of said diluted chemical.
