Abstract
A sleeve is provided for a frusto-conical beverage cup, configured to fit around the outside of the cup, thus protecting the fingers of the user from excessive temperatures in the case of a hot drink, and to provide a measure of insulation for the contents of the cup. The sleeve is an arcuate band of flexible, single-face corrugated material with curved side walls, oppositely extending slots adjacent the ends of the band and tabs lying alongside the slots, the tabs projecting only part-way across the width of the band, to facilitate the setting up of the sleeve.
