Apparatus and method for mixing and dispensing

Abstract

A system and method for mixing and dispensing two substances are provided. The system includes: a first substance a first container for containing a first substance, a second container for containing a second substance, a feeding tube, and a pumping system connected to the first container, the second container, and the feeding tube; wherein the system comprises at least three modes of operation: combining the first and second substances into one combined substance, mixing the combined substance, and dispensing the mixed substance; and wherein the pumping system is adapted to perform the at least three modes of operation and dispense the mixed substance to the feeding tube.

         33 . A mixing and dispensing apparatus, comprising:
 a first container for containing a first substance:   a second container for containing a second substance, the second container having a top including an input neck and an output neck, each of which is sealed by a sealing device;   an input pipe disposed inside the second container and attached to the sealing device at the input neck;   an output pipe disposed inside the second container and attached to the sealing device at the output neck;   a tube system configured to combine the first and second substances into one combined substance mix the combined substance, and dispense the mixed substance;   a feeding tube connected to the tube system and configured to receive the mixed substance from said tube system; and   a fluid-impermeable enclosure enclosing the first container, the second container, and the tube system,   wherein the tube system comprises:
 a main tube; 
 a first valve connected between the first container and one end of the main tube; 
 a second valve connected between the main tube and the feeding tube; and 
 a third valve connected between the main tube and the input neck, and 
   wherein the main tube comprises:
 a first tube section connecting the first valve and a first Y-connector; 
 a second tube section connecting the output neck and the first Y-connector; 
 a third tube section connecting the first Y-connector to a second Y-connector; 
 a fourth tube section connecting the second Y-connector to the third valve; 
 a fifth tube section connecting the second Y-connector to the second valve; and 
 a sixth tube section connecting the third valve to the input neck. 
   
     
     
         34 . The apparatus of  claim 33 , further comprising:
 the first substance; and   the second substance,   wherein first substance comprises an active disinfectant and the second substance comprises a diluting solution.   
     
     
         35 . The apparatus of  claim 33 , wherein the second container comprises an outer layer, an inner drum, and a space of insulation therebetween. 
     
     
         36 . The apparatus of  claim 33 , wherein the second container is a 200-liter container and the first container is smaller than the second container. 
     
     
         37 . The apparatus of  claim 33 , further comprising an exhaust pipe attached to the output neck, the exhaust pipe including an seventh tube section connected between the output neck and a fourth valve, and a eighth tube section connected between the fourth valve and an exhaust cap,
 wherein the exhaust cap includes a first filter.   
     
     
         38 . The apparatus of  claim 37 , further comprising a tube connected to the output neck and disposed inside the second container, the tube comprising a filter. 
     
     
         39 . The apparatus of  claim 37 ,
 wherein, during a combining of the first substance and the second substance, the first and third valves are configured to be opened and the second valve are configured to be closed,   wherein, during a mixing of the combined substance, the first and second valves are configured to be closed and the third and fourth valves are configured to be opened, and   wherein, during a dispensing of the mixed substance, the first and third valves are configured to be closed and the second and fourth valves are configured to be opened.   
     
     
         40 . The apparatus of  claim 33 , wherein the main tube and the feeding tube are flexible. 
     
     
         41 . The apparatus of  claim 33 , wherein the main tube and the feeding tube are hard pipes. 
     
     
         42 . The apparatus of  claim 33 , wherein the first container includes a body and at least one of a neck and a nozzle. 
     
     
         43 . The apparatus of  claim 33 , wherein the input pipe is approximately half the height of the second container. 
     
     
         44 . The apparatus of  claim 33 , wherein the output pipe extends almost to a bottom of the second container. 
     
     
         45 . The apparatus of  claim 33 , further comprising a peristaltic pump. 
     
     
         46 . The apparatus of  claim 33 , wherein the first and second Y-connectors are one-way connectors. 
     
     
         47 . The apparatus of  claim 33 , wherein the tube system is configured to combine only the first substance, the second substance, and air. 
     
     
         48 . The apparatus of  claim 33 , wherein the first container, the second container, and the tube system are enclosed in the fluid-impermeable enclosure without a pump. 
     
     
         49 . The apparatus of  claim 33 , wherein a pump is configured to be removably connected to the main tube and the main tube is configured to provide a fluid impermeable path from the first Y-connector to the second Y-connector regardless of whether the pump is connected to the main tube.
