Claim:
A beverage sleeve for a container, comprising: a first surface configured to contact the container and extend around a circumference of the container; a second surface configured to extend around the circumference of the container and face away from the container; and a securing device to hold the sleeve to an outside surface of the container, wherein a first portion of the securing device is provided on a first end of the sleeve on the first surface and when the sleeve is held to the container, the first portion is secured to a portion of the second surface, wherein an upper surface of the sleeve is formed of a substantially continuous non-planar surface, wherein the bottom surface of the sleeve includes a central non-planar segment and a non-planar side segment located on each side of the central non-planar segment, and wherein the central non-planar segment has a first radius of curvature and the non-planar side segments each have a same second radius of curvature, wherein the first and second radius of curvatures are different from each other, wherein a radius of curvature of the upper surface of the sleeve is smaller than a radius of curvature of the central segment of the bottom surface.
