Insulating container

Abstract

Disclosed herein are systems and methods for a container having a ceramic coating. The container includes an outer container having a first wall extending from a top edge to a bottom edge, an inner container received within the outer container having a second wall with an upper edge below the top edge of the outer container, a gap formed between the inner and outer containers, a handle coupled to the outer container, and a lid removably engaged with at least one of the first and second walls. The first wall has an intermediate section tapering between upper and lower sections, the ceramic coating is applied to an inner surface of the second wall from a lower edge to the top edge of the first wall to line an interior volume. The lid includes a mouth configured to receive a straw and disposed adjacent a perimeter edge of the lid.

         4 . The beverage container of  claim 1 , wherein the ceramic coating comprises multiple layers of the coating. 
     
     
         5 . The beverage container of  claim 1 , wherein the coating cutoff is between about 70% and about 100% of an inside surface height measured between the inner base and the top edge. 
     
     
         6 . The beverage container of  claim 5 , wherein the coating cutoff is between about 70% and about 90% of the inside surface height. 
     
     
         7 . The beverage container of  claim 1 , wherein the coating varies in thickness. 
     
     
         8 . The beverage container of  claim 1 , wherein the coating cutoff is disposed below a fastening portion that secures the lid to the container. 
     
     
         9 . The beverage container of  claim 1 , wherein the outer base seals a vacuum within the gap. 
     
     
         10 . The beverage container of  claim 1 , wherein the lid engages the first wall. 
     
     
         11 . A beverage container, comprising:
 an outer container having a first wall that extends continuously from a top edge to a bottom edge, wherein the outer container is substantially cylindrical and defines a longitudinal axis through a centerpoint defined by the top edge, wherein the outer container is made of metal;   an inner container received within and circumscribed by the outer container, the inner container having a second wall with an upper edge that is disposed below the top edge of the outer container, the second wall extending continuously from the upper edge to a lower edge that is adjacent an inner base, wherein the second wall is made of metal wherein an interior volume is defined between the top edge of the first wall and the inner base;   a gap formed between the inner container and the outer container between the upper edge and the bottom edge;   a handle coupled to an outer surface of body section of the outer container, the handle having a lowermost point that is disposed above the bottom edge of the outer container; and   a lid that is removably, sealingly engaged with at least one of the first wall and the second wall to cover the interior volume, the lid having an aperture that is configured to receive a straw therethrough, wherein the aperture is disposed adjacent to the longitudinal axis,   wherein a ceramic coating is applied to an entirety of an inner surface of the second wall from the lower edge to the upper edge and to an upper portion of an inner surface of the first wall to completely line the interior volume.   
     
     
         12 . The beverage container of  claim 11 , wherein the lid further includes a spout that is rotatable to selectively open and close the aperture. 
     
     
         13 . The beverage container of  claim 11 , wherein the ceramic coating comprises a composition including proportions of a polymethylsiloxane, silica sol dispersion, manganese ferrite spinel, water, aluminum oxide, and iron oxide red.
