Abstract
An insulating sleeve, preferably made of plastic, adapted to slidably receive and engage the outer sidewall of a container such as a cup. The sleeve is comprised of a plurality of concentric ring-like bands aligned one above the other and connected so as to form a unitary sleeve by peripheral ridges extending from the bottom edge of one band to the top edge of the next adjacent band. The sleeve is configured such that the top edge of each band rests in abutting engagement or contact with the sidewall when fitted around the container, with the remainder of the band and the associated ridge being located remote from contact with the container sidewall. A circular void or channel is thereby formed around the container between portions of the sleeve and the sidewall within an area defined by the top edges of adjoining bands. Heat or cold emanating from the container is accumulated within these channels and vented out the top of the sleeve via a series of notched vents provided within the top edge of each band.
