Abstract

Disclosed is a sleeve (313) for a cup containing a hot-beverage drink. The sleeve comprises a sheet comprising insulative cellular non-aromatic polymeric material. The material can allow for localized plastic deformation (e.g. 328) wherein the density of the material may be deferent in two adjacent portions of the sheet. Such a material can allow for forming of air gap(s) between the cup and the sleeve to improve the thermal insulation properties of the sleeve. An air gap can be formed such that the surface (326) of the sleeve is spaced apart from the exterior surface of the cup, minimising heat transfer between the cup and sleeve. The sleeve may be formed comprising a sleeve wall and a floor platform, wherein the floor platform is attached to the sleeve wall by retainer means. The floor platform can support at least a portion of the cup when in use. portions of the sheet.
