Containers for storing materials that can be selectively mixed or dispensed

Abstract

A composite container includes two containers that are axially aligned in movable toward each other to close a hole between the containers or away from each other to open the hole. When the hole is opened liquids, powder or other appropriate material in the containers can be mixed or intermingled ending up in either container or in both containers.

1 . A composite container comprising:
 a first container having first container body;   a second container having a second container body; and   an interconnecting device interconnecting said first and second container bodies selectively in one of a first configuration in which the two bodies are sealed from each other and a second configuration in which the bodies are in fluid communication thereby allowing contents from one body container to comingle with the contents of the second container.   
     
     
         2 . The composite container of  claim 1  wherein said first container body has a cylindrical sid wall and a bottom, said bottom having a hole and said interconnecting device includes a closing element selectively covers and uncovers said hole. 
     
     
         3 . The composite container of  claim 2  wherein said interconnecting device includes first threads on said first container body and second threads on said second body, wherein rotation of said container bodies with respect to each other cause said bodies to selectively approach and separate from each other along said threads. 
     
     
         4 . The composite container of  claim 2  wherein said interconnecting member includes a boss terminating in said head. 
     
     
         5 . The composite container of  claim 4  Wherein said boss is attached to said second container body. 
     
     
         6 . A composite container comprising:
 a first container having a cylindrical first container body and a first bottom with a hole, and a first engaging member disposed near said first bottom; and   a second container having a second body with a second bottom, a boss terminating in a closing member and a second engaging member;   wherein said first and second engaging members cooperating to selectively move said first and said container between a first and a second position;   wherein in said first position said closing member is in contact with said first bottom to close said hole, and in said second position, said hole is open allowing fluid communication between the interiors of said first and second containers.   
     
     
         7 . The composite container of  claim 6  wherein said first container has an outer wall and said first engaging member's a first thread on said outer wall. 
     
     
         8 . The composite container of  claim 7  wherein said second container has an inner wall and said second engaging member is a second thread on the inner wall, said first and second thread being coupled to each other. 
     
     
         9 . The composite container of  claim 8  wherein said container bodies are axially aligned and said hole and closing member are coaxial with said container bodies. 
     
     
         10 . The composite container of  claim 6  further comprising a container top constructed to attach said second container to close said container.
