Stackable liquid containment system

Abstract

A system is provided for storing and transporting a plurality of individual servings of a liquid. The system stores each serving in an individual container so that it is sealed from the external environment by the base of a container of another serving that is stacked directly on top of it.

1 . A stackable shot glass system for storing and transporting a plurality of individual servings of a liquid comprising:
 a first stackable shot glass comprising a base configured to be set on a flat surface and an interior liquid storage region,   a second stackable shot glass comprising a base configured to be set on a flat surface and an interior liquid storage region; and   means for coupling the first stackable shot glass to the second stackable shot glass by forming an airtight seal between the base of the first stackable shot glass and the interior liquid storage region of the second stackable shot glass so that the contents of the interior liquid storage region of the second stackable shot glass can be transported without spillage.   
     
     
         2 . The stackable shot glass system of  claim 1 , wherein the means for coupling comprises threading arranged on an exterior wall of the base of the first stackable shot glass and configured to mate in twisting engagement with corresponding threading arranged on an interior wall of the interior liquid storage region of the second stackable shot glass. 
     
     
         3 . The stackable shot glass system of  claim 1 , wherein the means for coupling comprises a gasket arranged around the circumference of the base of the first stackable shot glass, the gasket configured to mate in an interference fit with an interior wall of the interior liquid storage region of the second stackable shot glass. 
     
     
         4 . The stackable shot glass system of  claim 1 , further comprising a lid having a base configured form an airtight seal with an interior liquid storage region of the first stackable shot glass. 
     
     
         5 . The stackable shot glass system of  claim 4 , wherein the base of the lid has a gasket arranged around the circumference of the base, the gasket configured to mate in an interference fit with an interior wall of the interior liquid storage region of the first stackable shot glass. 
     
     
         6 . The stackable shot glass system of  claim 4 , wherein the base of the lid has threading arranged on an exterior wall of the base configured to mate in twisting engagement with corresponding threading arranged on an interior wall of the interior liquid storage region of the first stackable shot glass. 
     
     
         7 . The stackable shot glass system of  claim 4 , wherein the first stackable shot glass, the second stackable shot glass, each have an outermost sidewall of equal diameter. 
     
     
         8 . The stackable shot glass system of  claim 4 , wherein the means for coupling the first stackable shot glass to the second stackable shot glass is the same the lid configuration for coupling the lid to the first or to the second stackable shot glass. 
     
     
         9 . A method for using a stackable shot system comprising:
 providing at least two stackable shot glasses,   coupling a first stackable shot glass base into an interior liquid storage region of the second stackable shot glass to form an airtight seal between the first and second stackable shot glasses, and   coupling a lid to the first stackable shot glass to form an airtight seal between the first stackable shot glass and the lid,   wherein the first and second stackable shotglass, and the lid form an assembled stacking system.   
     
     
         10 . The method of  claim 9 , further comprising providing a third stackable shot glass and coupling an interior liquid storage region of the third stackable shot glass to a base of the second stackable shot glass to form a seal between the second and third stackable shot glasses. 
     
     
         11 . The method of  claim 9 , wherein each of the first stackable shot glass, the second stackable shot glass, and the lid include one of a gasket or threads for coupling. 
     
     
         12 . The method of  claim 11 , wherein each of the first stackable shot glass, the second stackable shot glass, and the lid include a base configured to be set on a flat surface. 
     
     
         13 . The method of  claim 11 , wherein each of the stackable shot glasses comprises a liquid in the interior liquid storage region. 
     
     
         14 . The method of  claim 13 , further comprising separating the third stackable shot glass from the second stackable shot glass to expose the liquid in the interior liquid storage region of the third stackable shot glass while maintaining the couplings between the first and second stackable shot glasses and the lid. 
     
     
         15 . The method of  claim 14 , further comprising separating the second stackable shot glass from the first stackable shot glass to expose the liquid in the interior liquid storage region of the second stackable shot glass while maintaining the couplings between the first stackable shot glass and the lid. 
     
     
         16 . The method of  claim 15 , further comprising separating the first stackable shot glass from the lid to expose the liquid in the interior liquid storage region of the first stackable shot glass.
