Patent ID: 8899441

Claim:
A heat-isolating cup sleeve, comprising: a main body formed into a sleeve having an inner surface and an outer surface, the sleeve adapted to encircle at least a portion of an outer surface of a cup; a die-cut part formed on the main body, the die-cut part comprises at least one severable part capable of forming a line of separation and at least one foldable part forming a fold line, inward finger pressure on the outer surface of the die-cut part partially separates the die-cut part from the remainder of the main body along the severable part and forces the die-cut part to fold inwardly along the fold line with respect to the outer surface of the remainder of the main body; when the die-cut part is pushed inwardly and rotated about the fold line, the die-cut part is adapted to be trapped between an inner surface of the main body and the outer surface of the cup and is adapted to form a fixer which wedges between the main body and cup creating a friction fit; at least a portion of the severable part contacts the remainder of the main body before the severable part is separated.
