Abstract
An insulating sleeve comprising a flat, elongated blank with straight top and bottom edges and end edges which are joined together at a glue flap. The sleeve includes a plurality of circumferentially spaced apart rows of generally longitudinally orientated and off-set slits. The rows of slits (5 to 10) are generally placed adjacent the glue flap and cover only a portion of the sleeve. Preferably at least one of the even or odd numbered slits extend to the top or bottom edge of the sleeve. In use, the sleeve is placed over the frustoconically shaped side wall of the cup which causes the sleeve to expand circumferentially until the desired fit is obtained.
Claims18
An insulating cup sleeve for encircling a frustoconical container having an open wider end located at the top of said container comprising:
- a) an elongate body having elongated and substantially straight top and bottom edges and first and second end side edges, said body being substantially flat when said elongate body is in an unassembled configuration and said body being substantially cylindrical when said elongate body is in an assembled configuration with said first and second end edges adhesively fastened to each other, said body in an assembled configuration defining an annular sleeve with top and bottom openings for receiving said container therein;
- and
- b) a plurality of circumferentially spaced apart, adjacent parallel rows of slits, the slits of one row being offset from the slits of adjacent rows;
- c) the plurality of slits being positioned about a circumferential segment of the frustoconically shaped container to allow the sleeve to expand circumferentially when positioned on a portion of the cup side wall.
