Manual Spray Cleaner

Abstract

A cleaning solution package comprising a dispensing container having a body with a closed bottom and an open upper end forming a neck and a dispensing valve mounted in the neck. A flexible pouch is mounted within the container and has an open upper end that is sealed to the dispensing valve. A cleaning composition containing an oxidizing agent is stored in the flexible pouch. A pressurized gas is between the container body and the flexible pouch to pressurize the cleaning solution within the flexible pouch.

1 . A cleaning solution package comprising:
 a dispensing container having a body with a closed bottom and an open upper end forming a neck and a dispensing valve mounted in the neck;   a flexible pouch mounted within the container having an open upper end that is sealed to the dispensing valve;   a cleaning composition including an oxidizing agent within the flexible pouch; and   a pressurized gas between the container body and the flexible pouch to pressurize the cleaning solution within the flexible pouch.   
     
     
         2 . The cleaning solution package according to  claim 1  wherein the flexible pouch is essentially free from interacting with the oxidizing agent. 
     
     
         3 . The cleaning solution package according to  claim 2  wherein the flexible pouch comprises multiple laminated layers, and wherein at least one of the multiple layers is a metallic layer. 
     
     
         4 . The cleaning solution package according to  claim 3  wherein the flexible pouch includes at least one polyamide layer. 
     
     
         5 . The cleaning solution package according to  claim 3  wherein the flexible pouch includes at least one polyethylene terephthalate layer. 
     
     
         6 . The cleaning solution package according to  claim 3  wherein the flexible pouch includes at least one polypropylene layer. 
     
     
         7 . The flexible pouch according to  claim 3  further comprising an adhesive between at least two of the multiple layers. 
     
     
         8 . The cleaning solution package according to  claim 1  wherein the oxidizing agent is hydrogen peroxide. 
     
     
         9 . The cleaning solution package according to  claim 1  and further comprising an aqueous carrier and at least one surfactant. 
     
     
         10 . The cleaning solution package according to  claim 9  wherein the aqueous carrier is deionized water. 
     
     
         11 . The cleaning solution package according to  claim 9  wherein the at least one surfactant is biodegradable. 
     
     
         12 . The cleaning solution package according to  claim 1  and further comprising at least one organic solvent. 
     
     
         13 . The cleaning solution package according to  claim 12  wherein the at least one organic solvent is selected from the group consisting of glycol ethers including propylene glycol methyl ether, dipropylene glycol methyl ether, tripropylene glycol methyl ether, and diethylene glycol n-butyl ether. 
     
     
         14 . The cleaning solution package according to  claim 13  further comprising at least one of an anti-soil and anti-stain agent selected from the group consisting of polymers and copolymers based on acrylic monomers, polyhedral oligomeric silsesquioxane monomers and derivatives thereof. 
     
     
         15 . The cleaning solution package according to  claim 1  wherein the cleaning composition is free of volatile organic carbon compounds. 
     
     
         16 . The cleaning solution package according to  claim 15  further comprising at least one organic acid in an effective amount to act as a chelating agent and an oxidizing agent stabilizer and wherein the solution package meets the United States Environmental Protection Agency's “Design for the Environment” standards. 
     
     
         17 . The cleaning solution package according to  claim 16  wherein the at least one organic acid is citric acid. 
     
     
         18 . The cleaning solution package according to  claim 1  wherein the pressurized gas is free of volatile organic carbon compounds. 
     
     
         19 . The cleaning solution package according to  claim 18  wherein the pressurized gas is selected from at least one of air and nitrogen. 
     
     
         20 . A method for making a cleaning solution package comprising:
 sealing a flexible pouch having an open end to a dispensing valve;   positioning the flexible pouch within an open top container with the dispensing valve in registry with the open top of the container, to provide a space between the flexible pouch and an inside surface of the container;   sealing the dispensing valve to the open top of the container;   injecting a gas into the space between the flexible pouch and an inside surface of the container to pressurize the space;   filling the flexible pouch with a cleaning solution containing an oxidizing agent.
