Portable unit and wall unit dispensers and method of dispensing with timer

A system for dispensing a final concentration of product dispensed by multiple delivery units, comprising:

• a) a first dispenser, comprising:
• i) an aspirator having a liquid diluent inlet, an inlet for liquid concentrate and an outlet for a first dilute solution, the aspirator being readily modified for varying the concentration of the first dilute solution;
• ii) a valve operably connected to the aspirator for controlling flow of liquid diluent from a source of liquid diluent to the aspirator inlet;
• and
• iii) a first bottle to receive the first dilute solution from the aspirator outlet;
• b) a portable self-contained delivery/dilution unit, the unit comprising:
• i) the first bottle of the first dilute solution;
• ii) a fillable and emptiable reservoir containing liquid diluent;
• iii) an aspirator, having a setting for delivering out its outlet a second dilute solution;
• iv) pump to control flow into and out of the aspirator;
• v) a spray member in fluid communication with the outlet of the aspirator, wherein the second dilute solution is dispensed by a user;
• and
• c) the unit is useable by a respective user and wherein a concentration of the second dilute solution in each portable unit is controllable by a concentration of the first dilute solution which is readily modified, thereby allowing different concentrates to be used by the portable units without modifying the multiple portable units.

A portable self-contained dispensing system, that can contact surfaces with a first liquid spray followed by a second spray, the system comprising:

• a) a fillable and emptiable container, for a volume of an aqueous diluent of less than 10 liters;
• b) a dilution section, having a dry portion and a wet portion;
• i) the wet portion comprising a venturi and a wet portion of a pump, wherein a pump intake is in liquid communication between the container and a pump inlet, a pump outlet is in liquid communication between the pump and the venturi, the venturi comprising a concentrate inlet and the venturi in liquid communication with an outlet;
• and
• ii) the dry portion of the station comprising a battery, a dry portion of the pump and sufficient wiring to power the pump;
• c) a source of concentrate in liquid communication with the concentrate inlet of the venturi;
• d) spray means in separate liquid communication with the venturi outlet and another outlet, comprising a valve that can select either a first liquid spray or a second liquid spray;
• wherein the pump has a pumping capacity of up to about 2000 to 3000 mL/min and the system, with the container filled with an effective amount of diluent, weighs less than 7 kg;
• e) a first timer energized by activation of the portable system;
• and
• f) a first indicator operatively connected to the first timer, wherein when the first timer has expired, the first indicator will notify the user sufficient second dilution solution has been dispensed.

A portable self-contained dispensing system, comprising:

• a) a fillable and emptiable container for holding an aqueous diluent;
• b) a dilution section operatively connected to the container, the dilution section comprising:
• i) a pump having an inlet in fluid communication with the container and an outlet in fluid communication with first and second aspirators, each aspirator having an inlet and an outlet;
• ii) a power source operatively connected to the pump;
• iii) a first source of concentrate in fluid communication with the inlet of the first aspirator;
• iv) a second source of concentrate in fluid communication with the inlet of the second aspirator;
• c) a spray member in fluid communication with the first and second aspirator outlets;
• d) a first bottle for holding the first concentrate and a second bottle for holding the second concentrate;
• e) a valve to control fluid flow from the first and second aspirators, wherein the pump pressurizes flow from both aspirators and the valve blocks flow through one of the aspirators as the other of the aspirators operates;
• f) a first timer energized by activation of the portable system;
• and
• g) a first indicator operatively connected to the first timer, wherein when the first timer has expired, the first indicator will notify the user sufficient second dilution solution has been dispensed.
