Liquid storage container with adjustable internal volume

Abstract

A liquid storage container having an adjustable internal volume for the removal of vacant air space is disclosed. The liquid storage container comprises a tubular sleeve having a top lid portion and a bottom plunger having an outer gasket housed within the sleeve. In use, liquid from a first container is added or liquid is removed from the liquid storage container wherein the bottom plunger is sized and shaped to facilitate manual movement of the plunger either up or down within the sleeve. During the plungers movement the outer gasket engages the interior of the sleeve for providing a liquid tight arrangement while simultaneously allowing the bottom plunger to telescopically move up or down within the sleeve in response to applied forces adjusting the liquid storage containers internal volume for the removal of vacant air space or for allowing a liquid to be added to the liquid storage container.

What is claimed is: 
     
         1 . A liquid storage container having an adjustable internal volume, comprising:
 a tubular sleeve having a removable top lid portion;   said tubular sleeve housing a bottom plunger having an outer gasket and plunger handle;   wherein said bottom plunger is sized and shaped to facilitate manual movement of said plunger within said sleeve for adjusting the liquid storage containers internal volume.   
     
     
         2 . The storage container according to  claim 1 , wherein said outer gasket engages an interior of said sleeve for providing a liquid tight arrangement while simultaneously allowing said bottom plunger to telescopically move up within said sleeve in response to an applied force using said plunger handle thereby removing vacant air space within the liquid storage container. 
     
     
         3 . The storage container according to  claim 1 , wherein said outer gasket engages an interior of said sleeve for providing a liquid tight arrangement while simultaneously allowing said bottom plunger to telescopically move down within said sleeve in response to an applied force using said plunger handle thereby allowing additional liquid to be added to the liquid storage container. 
     
     
         4 . The storage container according to  claim 1 , wherein said tubular sleeve defines a wall thickness sufficient to house a liquid having an internal pressure between 80 to 120 psi. 
     
     
         5 . The storage container according to  claim 1 , wherein said tubular sleeve defines a circumference large enough to allow said plunger handle to be griped and rotated by hand. 
     
     
         6 . The storage container according to  claim 1 , wherein said tubular sleeve is transparent or semi-transparent when used for storing carbonated sodas. 
     
     
         7 . The storage container according to  claim 1 , wherein said plunger handle is a wrench and socket combination for cranking said plunger up and down. 
     
     
         8 . A liquid storage container having an adjustable internal volume, comprising:
 a tubular sleeve having a removable top lid portion and defining an internal screw thread pattern;   said tubular sleeve housing a bottom plunger defining an external screw thread pattern and a plunger handle; wherein said bottom plunger is sized and shaped to facilitate manual movement of said plunger by mating said plunger's screw thread pattern within said sleeves screw thread pattern for adjusting the liquid storage containers internal volume.   
     
     
         9 . The storage container according to  claim 8 , wherein said outer gasket engages an interior of said sleeve for providing a liquid tight arrangement while simultaneously allowing said bottom plunger to telescopically move up within said sleeve in response to an applied force by rotating said plunger handle thereby removing vacant air space within the liquid storage container. 
     
     
         10 . The storage container according to  claim 8 , wherein said outer gasket engages an interior of said sleeve for providing a liquid tight arrangement while simultaneously allowing said bottom plunger to telescopically move down within said sleeve in response to an applied force by rotating said plunger handle thereby allowing additional liquid to be added to the liquid storage container. 
     
     
         11 . The storage container according to  claim 8 , wherein said tubular sleeve is darkly tinted or opaque when used for storing wines. 
     
     
         12 . The storage container according to  claim 8 , wherein said plunger handle is a wrench and socket combination for cranking said plunger up and down.
