Method of mixing a liquid in a container
View Patent ↗Presently, there exists a need for a method of mixing (stirring) the ingredients of a liquid preparation within a container without the introduction of any device or manual implement to agitate the contents mechanically. The purpose of the present invention is to provide a method a convenient, economical and effective method of mixing utilizing a chemical reaction to facilitate liquid motion in a container without the use of a stirring implement or external mechanical intervention.
1. A vessel or container comprising: (a) one or more compounds affixed by a binder to an inside surface of the vessel or container; and (b) one or more microcapsules affixed by the binder to the inside surface of the vessel or container; wherein the one or more compounds are incorporated into the binder; wherein the one or more compounds are capable of causing a reaction-induced disturbance in a liquid upon introduction of the liquid into the vessel or container for the purpose of mixing the contents therein; wherein the binder comprises an amphiphilic polymer; wherein the binder envelops the one or more compounds; and wherein the binder maintains the one or more compounds in an anhydrous state prior to the introduction of the liquid into the vessel or container.
2. The vessel or container of claim 1 wherein the one or more compounds affixed thereto when hydrated create an effervescent reaction sufficient to cause a mixing action in a liquid as the resultant release of CO 2 gas bubbles pass through the liquid to the surface.
3. The vessel or container of claim 1 wherein the reaction-induced disturbance is initiated by the introduction of a liquid into the container causing the dissolution of the binder and the exposure of said compounds thus allowing them to react.
4. The vessel or container of claim 1 wherein the amphiphilic polymer comprises a vinylpyrrolidone-vinyl acetate copolymer.
5. The vessel or container of claim 1 wherein said compounds comprise an acid.
6. The vessel or container of claim 1 wherein said compounds comprise a carbonate-containing compound.
7. The vessel or container of claim 6 wherein the carbonate-containing compound has been heat-treated to cause a micron layer of inactive material on the surface of the carbonate to inhibit premature reaction when in intimate contact with an acid prior to hydration.
8. The vessel or container of claim 1 wherein the binder is comprised substantially of the amphiphilic polymer.
9. The vessel or container of claim 1 wherein the amphiphilic polymer comprises Hydroxypropyl cellulose.
10. The vessel or container of claim 1 , wherein the reaction of the one or more compounds with the liquid causes the reaction-induced disturbance in the liquid.
