Interlocking receptacles

Abstract

A liquid receptacle system for storing and pouring a liquid, comprising a storage receptacle and a receiving receptacle. The storage receptacle is configured for storing the liquid therein and pouring the liquid therefrom. The storage receptacle has a first storage volume. The receiving receptacle has a second storage volume which is greater than the first storage volume. The receiving receptacle is configured for receiving the liquid poured from the storage receptacle. The receiving receptacle has a surface configured to cover the storage receptacle. The storage receptacle and the surface of the receiving receptacle have complementary interlocking features configured for preventing substantial spillage of the liquid stored in the storage receptacle.

1 . A liquid receptacle system for storing and pouring liquid, comprising: 
 (a) a first storage receptacle configured for storing the liquid therein and pouring liquid therefrom, said first storage receptacle having a first storage volume; and    (b) a receiving receptacle having a second storage volume which is greater than said first storage volume; said receiving receptacle being configured for receiving said liquid poured from said first storage receptacle, said receiving receptacle having a surface configured to cover said first storage receptacle, said first storage receptacle and said surface of said receiving receptacle having a first set of complementary interlocking features configured for preventing substantial spillage of said liquid stored in said first storage receptacle.    
   
   
       2 . The system of  claim 1 , further comprising a second storage receptacle configured for storing a second liquid therein and pouring therefrom into said receiving receptacle, said second storage receptacle having a third storage volume, a sum of said first storage volume and said third storage volume being less than said second storage volume, said second storage receptacle and said receiving receptacle having a second set of complementary interlocking features configured for preventing substantial spillage of said second liquid stored in said second storage receptacle.  
   
   
       3 . The system of  claim 1 , wherein said surface is an inner surface of said receiving receptacle.  
   
   
       4 . The system of  claim 1 , wherein said complementary interlocking features include a first screw thread disposed on said first storage receptacle and a second screw thread disposed on said receiving receptacle.  
   
   
       5 . The system of  claim 1 , wherein said first storage receptacle has a handle disposed thereon configured for convenient pouring of said liquid from said first storage receptacle.  
   
   
       6 . The system of  claim 1 , wherein said first storage receptacle has two handles disposed thereon configured for convenient pouring of said liquid from said first storage receptacle.  
   
   
       7 . The system of  claim 1 , wherein: 
 (a) said first storage volume is greater than half a liter; and    (b) said receiving receptacle has an opening having a minimum dimension of at least 18 cm.    
   
   
       8 . A method for storing and pouring a liquid, comprising the steps of: 
 (a) disposing the liquid into a storage receptacle;    (b) interlocking said storage receptacle with a receiving receptacle in order to prevent substantial spillage of the liquid from said storage receptacle;    (c) disconnecting said storage receptacle from said receiving receptacle; and    (d) pouring the liquid from said storage receptacle into said receiving receptacle.    
   
   
       9 . The method of  claim 8 , wherein: 
 (a) said liquid is water; and    (b) said step of pouring is performed by pouring the water from said storage receptacle over a hand into said receiving receptacle.    
   
   
       10 . The method of  claim 8 , wherein said step of interlocking is performed by screwing together said storage receptacle and said receiving receptacle.
