An insulator wrap for a beverage container is formed by a substantially rectangular body of insulation material. A self-coiling spring strip is embedded in the body along approximately the longitudinal center line. Because the spring strip is curved in lateral cross section, the wrap is held straight when uncoiled to allow easy storage and handling when not in use. Simple manual pressure frees the spring strip to self-coil inwardly to cause the wrap to extend around the container for use. Extended portions of the rectangular body isolate the spring strip from the edges of the body. In one embodiment, the extended body portions are one and one half times as wide as the spring strip. A foam insert is positioned within the elongated concave trough of the spring strip to provide a substantially smooth display surface for graphics and indicia in either the uncoiled or self-coiled states. Stiffening stays are embedded laterally across the ends of the body to provide additional snugging force and to hold the top and bottom corners of the body securely against the container during use.
