Fluid vessel combinable with cups

Abstract

There's disclosed a combination of a vessel for containing fluid with a cup and a fastening device. The fastening device attaches outer sidewalls of the vessel to inner sidewalls of the cup. In embodiments, the vessel is combined with a plurality of cups having an external cup containing a number of internal cups that includes an innermost internal cup placeable onto the lower outer sidewalls of the vessel. The fastening device can be represented in the form of a peripheral collar on the vessel's sidewalls and a counterpart cutoff on the cup's sidewalls, or of peripheral cutoffs made on the vessel's and cup's sidewalls with a resilient tightening element placed therebetween, or screw threadings on the vessel's and cup's sidewalls. The sidewalls can be circular or ribbed. The vessel and cup can be made of glass, metal, or plastic. The vessel-cup combination is convenient to use, and easy to transport.

I claim: 
     
         1 . A combination of a vessel for containing fluid with a cup and with a means for fastening the cup to the vessel, wherein:
 said vessel has a lower portion with outer sidewalls;   said cup has inner sidewalls; and   said means for fastening attach said outer sidewalls of the lower portion of the vessel to said inner sidewalls of the cup.   
     
     
         2 . The combination according to  claim 1 , wherein said outer sidewalls of the lower portion of the vessel and said inner sidewalls of the cup have cross-sections configured as a closed curvilinear contour, or as a polygon contour. 
     
     
         3 . The combination according to  claim 1 , wherein said cup is configured as a container with gauge marks. 
     
     
         4 . The combination according to  claim 1 , wherein said vessel and said cup are made of at least one of the following materials: glass, metal, and plastic. 
     
     
         5 . A combination of a vessel for containing fluid with a plurality of N cups and with a means for fastening said plurality of N cups to the vessel, wherein
 said vessel has a lower portion with outer sidewalls;   said plurality of N cups consists of:
 N−1 internal cups including an innermost internal cup having a size such that the lower portion of the vessel can be inserted into the innermost cup, and an outermost internal cup having a maximal size and a maximal height among the internal cups; and 
 an external cup having a size and a height predeterminedly greater than the maximal size and the maximal height of the outermost internal cup; said external cup has inner sidewalls; 
   wherein said internal cups are correspondingly inserted into each other and the outermost internal cup is inserted into the external cup; and   said means for fastening attach said outer sidewalls of the lower portion of the vessel to said inner sidewalls of the external cup.   
     
     
         6 . The combination according to  claim 5 , wherein said outer sidewalls of the lower portion of the vessel and said inner sidewalls of the cups of said plurality of N cups have cross-sections configured as a closed curvilinear contour, or as a polygon contour. 
     
     
         7 . The combination according to  claim 1 , wherein said vessel and the cups of said plurality of N cups are made of at least one of the following materials: glass, metal, and plastic.
