Beverage container

Abstract

A dispending bottle having an open top closed by a cap with a stopper-type drinking valve, and two separate compartments or chambers in upper and lower sections of the bottle joined together by a rotary coupler permitting twisting of the top and bottom sections in opposite direction to open a mixing valve in the mid portion of the bottle. Spiral ribs facilitate gripping and twisting, and flexible walls facilitate mixing.

1 . A beverage bottle having a top opening normally closed by a cap having a stopper-type drinking valve therein, said container comprising top and bottom bottle sections composed of flexible material and defining first and second chambers for products to be dispensed, said sections being substantially circular in cross-section and each having an open end in the mid section of the bottle, said top section having said top opening therein opposite the open end thereof and said bottom section having a closed bottom end opposite the open end thereof; 
 a coupling element disposed between said top and bottom sections and secured thereto to seal said open ends and join the two sections together into a unitary bottle;    and a valve in said coupling element normally disposed in a closed position to separate said chambers and operable in response to twisting of said sections relative to each other to open the valve and establish communication between said chambers.    
   
   
       2 . A beverage bottle as defined in  claim 1  further including generally spiraling external ribs on said sections facilitating gripping thereof for twisting.  
   
   
       3 . A beverage bottle as defined in  claim 2  wherein said ribs spiral around said sections in opposite directions.  
   
   
       4 . A beverage as defined in  claim 1  wherein said valve comprises two shallow cups each having a flange as a sidewall overlapping and joined to the sidewall of one of said sections.  
   
   
       5 . A beverage bottle as defined in  claim 4  wherein the cups of said coupling element have relatively rotatable bottom walls each formed with at least one valve opening that is closed by the other cup when the cups are in one angular position and open through an opening in the other cup in another angular position.  
   
   
       6 . A beverage bottle as defined in  claim 5  wherein each valve wall has a plurality of generally radially extending openings separated by imperforate areas for covering and closing the openings in the other valve wall in said one angular position.  
   
   
       7 . A beverage bottle as defined in  claim 1  wherein said coupling element comprises first and second cup-shaped members secured to the top and bottom bottle sections, respectively, and having bottom walls abutting against each other and rotatably secured together, each of said bottom walls having at least one valve opening therein that normally is covered and closed by the other bottom wall and is movable into communication with the other valve openings to connect the chambers for flow of product through the valve.  
   
   
       8 . A container for beverages and the like, having two container sections dispensed in end-to-end relation and each adapted to hold product to be dispensed, one of said sections having a dispensing opening in one end and the other having a closed end for forming the bottom of the container; 
 a coupling disposed between said container sections and joining them together for relative twisting rotation between said ends;    and a valve disposed between said container sections and normally closed to maintain the container sections separate, said valve being operable by twisting of the containers to establish communication between the container sections.    
   
   
       9 . A container as defined in  claim 8  wherein said coupling comprises two cup-shaped members connected to open ends of the container section and normally closing and sealing the same, said members being relatively rotatable by twisting of the container sections to establish communication between the container sections in one angular position of the members.  
   
   
       10 . A container as defined in  claim 8  wherein said container sections are upper and lower sections of a bottle rotatably joined by said coupling for twisting motion, and said valve is built into said coupling.  
   
   
       11 . A container as defined in  claim 10  wherein said bottle sections are composed of resiliently flexible material and formed with spiral ribs on their exterior surfaces.  
   
   
       12 . A container as defined in  claim 11  wherein said dispensing opening is at the end of said one section remote from the coupling member and is normally closed by a cap having a stopper-type drinking valve.
