Thermos flasks' cool image

A London advertising agency has taken on one of the toughest challenges in marketing - making Thermos flasks cool.

Trevor Beattie, creative director of TBWA and the man behind the award- winning Wonderbra advertisements, has been given the job of helping create a hip new image for the drink containers, often viewed as the packed-lunch companion of anorak-clad trainspotters and elderly couples at the seaside.

The pounds 500,000 campaign, under the catchline "Thermos - The Flask Just Got Hot", willrun for two weeks and will be initially test-launched at sites in railway stations, motorway service areas and shopping centres in Britain and France.
