A thermal insulating device, particularly suitable for maintaining the chilled state of a wine bottle, comprises an outer paperboard tube (2), an inner paperboard tube (3) and a base (7). The base (7) is supported on an inwardly rolled bead (8) formed on the outer paperboard tube and the inner paperboard tube is formed with an appropriate profile to space it from the paperboard tube to define a cavity (6) therebetween. The device may be provided with a lid. The device provides a low cost insulating device which may be used for the retail sale of pre-chilled wines or other beverages. <IMAGE>
