<P>PROBLEM TO BE SOLVED: To provide a drinking water storage vessel capable of being held with a bare hand under its heated state without bringing about substantially increased costs and at the same time capable of reducing an amount of produced dew when the vessel is held at a room temperature under its cooled state. <P>SOLUTION: There is provided a drinking water storage vessel in which a vessel body 1 is formed into a cylindrical shape with metals such as aluminum or steel and the like. Many grooves 2 are arranged side-by-side at the surface of a barrel 11 of the vessel body 1 with a circumferential predetermined spacing. A heat shrinkage resin film 3 is thermally shrunk at the outer surface of the barrel and the heat shrinkage resin film 3 is abutted against and supported at each of protrusions 21 constituted by many grooves 2 and a hollow part 4 is formed between respective notches 22 and the heat shrinkage resin film 3, and then the grooves 2 are formed such that an area of the part where the heat shrinkage resin film 3 abuts against each of the protrusions 21 may become smaller than a projected area of a non-contact part against the surface of the film 3. <P>COPYRIGHT: (C)2004,JPO |
