Instant Drink Hot Beverage Container

Abstract

A beverage container composed of a heat conductive outer shell, an insulated inner container, and a lid that together interlock so as to create a channel along the inside wall of the outer shell. The beverage container is designed such that when tilted for consumption, liquid is funneled up from the base of the insulated inner container through the channel to the lip. The heat conductive outer shell cools the beverage in transit through the channel by absorbing the heat and radiating it into the ambient environment.

1 . A beverage container comprising: a) an inner core, comprising: a body having an open top, a bottom, and side walls with an inner surface forming a central chamber for fluids and a cylindrical outer surface having a circumference, the bottom of the inner core being pierced by a hole running from the interior of the core to the exterior; and b) an outer shell surrounding the inner core, comprising: a body having an open top, a bottom, and side walls having an outer surface and an inner surface enclosing a cylindrical central chamber having a circumference fitting tightly to the cylindrical outer surface of the inner core; at least one vertical groove running from the top of the interior wall of the outer shell to the bottom of the interior of the outer shell and continuing under the inner core, said groove being aligned with the hole in the base of the inner core such that when the inner core and outer shell are combined at least one channel is created through which liquid can flow from the interior of the inner core, through the hole in the base of the inner core, up the groove to the top of the exterior shell; and c) a cap covering the open top of both the outer shell and inner core, said cap having at least two holes, one aligned with the channel and the other aligned directly with the central chamber of the inner core. 
     
     
         2 . The beverage container of  claim 1 , in which the outer shell is made of heat conducting material. 
     
     
         3 . The beverage container of  claim 1 , in which the outer shell incorporates a heat sink in the form of excess heat conducting materials. 
     
     
         4 . The beverage container of  claim 1 , in which the outer shell incorporates one or more fins on the exterior surface. 
     
     
         5 . The beverage container of  claim 1 , in which the vertical grooves on the interior wall incorporate one or more fins. 
     
     
         6 . The beverage container of  claim 1 , in which the inner core is made of insulating material. 
     
     
         7 . The beverage container of  claim 1 , further comprising a handle fastened to or built into the outer shell or inner core. 
     
     
         8 . The beverage container of  claim 1 , in which the inner core incorporates a flow restriction device that allows liquid to flow out of the bottom hole into the grooves but not vice versa. 
     
     
         9 . The beverage container of  claim 1 , in which the cap incorporates a rotating disc that allows the holes in the cap to be sealed entirely or selectively.
