Multiple Chamber Fluid Container

Abstract

A multiple chamber stackable cup or bottle has an air space separation between the chambers. A rotatable cap with a single sealable spout pivots to access each chamber individually. Alternately, a stationary cap has multiple sealable openings, one for each chamber, which communicate one chamber at a time or can be placed to bridge both chambers to allow access to both chambers at the same time. Tapered bodies enable the multiple chamber bodies to be stacked in a nested array.

1 . A multiple chamber fluid container comprising:
 a multiple fluid container body comprising at least two separate fluid chambers each comprising separate surrounding walls and a separate bottom, each enclosing a separate interior space for containing a fluid;   a top chamber opening for accessing the interior spaces;   each fluid chamber comprising a separate body portion spaced apart from the body portion of each other body portion by an air space between adjacent wall portions;   each of the body portions having rigid surrounding walls and a rigid bottom to prevent contact between body portions to insulate each body portion from each other body portion to allow a fluid of one temperature to be contained in one of the at least two separate fluid chambers and a fluid of a different temperature to be contained in each of the other at least two separate chambers;   the at least two separate fluid chambers interconnected at the top chamber opening by an interconnecting ridge between the adjacent wall portions and a common top lip at a top edge of non-adjacent wall portions to form a larger shared fluid container body opening accessing the top chamber openings of each of the separate fluid chambers;   each of the at least two separate fluid chambers configured with tapering wall surfaces narrower at the bottom to stack a plurality of fluid container bodies together in a nested array for storing or shipping empty containers;   a cap comprising a top surface and surrounding downwardly facing channel around an outer edge of the top surface, the channel removably mating with the shared top lip to seal the multiple fluid container opening and means for sealing each of the at least two fluid chambers to retain a fluid therein separately from a fluid in any other fluid chamber;   at least one fluid access opening formed in the top surface for accessing each of the interior spaces of the at least two separated fluid chambers, and   said at least one fluid access opening in said cap can be oriented to provide access to one or both of said two separate fluid chambers simultaneously to provide a means for accessing one or both of the at least one opening at a time to access one or both of the at least two separated fluid chambers from a single fluid access opening.   
     
     
         2 . The multiple chamber fluid container of  claim 1  wherein the means for sealing each of the at least two fluid chambers comprises a portion of the cap contacting the interconnecting ridge between the adjacent wall portions to separate the top chamber openings of the at least two fluid chambers. 
     
     
         3 . The multiple chamber fluid container of  claim 2  wherein the cap has a separate fluid access opening for each of the at least two separate fluid chambers and the means for accessing one of the at least one fluid access opening at a time comprises a sealing tab over each of the separate fluid access openings. 
     
     
         4 . The multiple chamber fluid container of  claim 3  wherein the at least two separate fluid chambers are fabricated of a thermally insulating disposable synthetic material the cap is fabricated of molded plastic, and the sealing tabs are molded into the caps with living hinges to open and close the sealing tabs. 
     
     
         5 . The multiple chamber fluid container of  claim 1  wherein the at least two separate fluid chambers are fabricated of a thermally insulating material. 
     
     
         6 . The multiple chamber fluid container of  claim 1  wherein when the lid is placed to provide access to both chambers from the single opening a user can drink from the single opening to consume fluid from both chambers from the single opening. 
     
     
         7 . The multiple chamber fluid container of  claim 1  that further includes a drinking straw. 
     
     
         8 . The multiple chamber fluid container of  claim 7  wherein the drinking straw has two openings at a first end and one opening at a second end. 
     
     
         9 . The multiple chamber fluid container of  claim 7  wherein the two opening first end can be placed in either a single fluid chamber or can be placed with an opening in each fluid chamber. 
     
     
         10 . The multiple chamber fluid container of  claim 7  wherein said straw allows mixing of fluids draws from said two openings at the first end into the one opening at the second end.
