Claims11
An insulating holder for a hot beverage cup having a conical section, said holder providing thermal protection to the hand of a user holding said cup, said holder consisting essentially of
- a sleeve including a stripe of strong thermally insulating card stock having two folds, said folds being angled to each other and dividing said stripe into a left end section, a center section, and a right end section;
- said center section having a length of half the circumference of said beverage cup;
- said left and right end sections providing an inside and an outside surface when said left end section and said right end section are folded inwardly over said center section;
- said left and right end sections having a total length exceeding the length of said center section for providing overlapping bonding areas for bonding the inside of said bonding area of one of said end sections to the underlying outside of said bonding area of the other one of said end sections;
- said so bonded left and right end sections providing a half section equal in length to said center section, said center section and said half section forming said sleeve;
- said folds adapting said sleeve for storage in a flat folded configuration and for receiving said beverage cup in an open configuration;
- said card board having a stiffness providing a clamping force onto said received beverage cup;
- said shape of said insulating holder partially conforming with said conical section of said hot beverage cup.
