Beverage container insulating device

Abstract

A beverage container insulating device includes an outer wall and at least one protrusion. The outer wall defines an internal cavity and an orifice that accesses the internal cavity. The at least one protrusion extends into the internal cavity from an internal surface of the outer wall. The protrusion is configured to engage a beverage container when inserted into the internal cavity via an interference-fit such that the protrusion deforms the beverage container and affixes the position of the beverage container within the internal cavity.

         6 . The beverage can insulating device of  claim 4 , wherein side wall has a length that extends from the bottom wall to the orifice, and wherein the first horizontally aligned row of protrusions is disposed along, the side wall at a distance from the orifice that ranges between zero and ½ of the length of the side wall. 
     
     
         7 . The beverage can insulating device of  claim 4 , wherein the plurality of protrusions forms a second horizontally aligned row of protrusions. 
     
     
         8 . The beverage can insulating device of  claim 7 , wherein the first horizontally aligned row of protrusions and the second horizontally aligned row of protrusions form vertically aligned columns of protrusions. 
     
     
         9 . The beverage can insulating device of  claim 1 , wherein the internal cavity is sized such that there is clearance between the internal surface of the side wall and the beverage can when inserted into the internal cavity. 
     
     
         10 . A beverage container insulating device comprising:
 a bottom wall; and   a side wall extending about an outer periphery of the bottom wall such that the bottom wall and the side wall define an internal cavity that is configured to receive a beverage container, the side wall defining an orifice that accesses the internal cavity on an opposing end of the beverage container insulating device relative to the bottom wall, the side wall having an inner diameter that is sized such that there is clearance between an internal surface of the side wall and the beverage container when inserted into the internal cavity; and   at least one protrusion extending into the internal cavity from the internal surface, wherein the at least one protrusion is configured to engage the beverage container when inserted into the internal cavity via an interference-fit such that the at least one protrusion deforms the beverage container and affixes the position of the beverage container within the internal cavity.   
     
     
         11 . The beverage container insulating device of  claim 10 , wherein each of the at least one protrusion has a first ramped surface that extends gradually away from the side wall and into the internal cavity along a length of each of the at least one protrusion, the length of each of the at least one protrusion extending in an axial direction of the beverage container insulating device from the orifice to the bottom wall. 
     
     
         12 . The beverage container insulating device of  claim 11 , wherein each of the at least one protrusion has a second ramped surface that extends gradually away from the first ramped surface and to the side wall along the length of each of the at least one protrusion. 
     
     
         13 . The beverage container insulating device of  claim 10 , wherein the at least one protrusion includes a plurality of protrusions that forms a first horizontally aligned row of protrusions. 
     
     
         14 . The beverage container insulating device of  claim 13 , wherein the side wall has a length that extends from the bottom wall to the orifice, and wherein the first horizontally aligned row of protrusions is disposed along the side wall at a distance from the bottom wall that ranges between zero and ½ of the length of the side wall. 
     
     
         15 . The beverage container insulating device of  claim 13 , wherein side wall has a length that extends from the bottom wall to the orifice, and wherein the first horizontally aligned row of protrusions is disposed along the side wall at a distance from the orifice that ranges between zero and ½ of the length of the side wall.
