<P>PROBLEM TO BE SOLVED: To provide a cold reserving implement for a bottle which is easily attached to/detached from a bottle and prevents temperature of a hand from being propagated. <P>SOLUTION: The bottomed cylindrical container-shaped cold reserving implement for the bottle is configured to house the bottle so as to expose a portion above a narrowed part B3 forming a narrow opening B4 at the upper part of the bottle B and cover a bottom part B1 and a side part B2 of the bottle B, and includes: a flexible heat insulating material 2 formed in fixed layer thickness such that its side surface 2a has an inside diameter L somewhat larger than an outside diameter W of the side part B2 of the bottle B, and the side part 2a and a bottom part 2b can be insulated from heat; a resilient hard coating material 1 formed in thin and fixed layer thickness such that the outer peripheries of the bottom part 2b and the side part 2a of the heat insulating material 2 are covered; a bottle contact band 3 having resiliency and formed such that its inner peripheral surface provided around an inner surface near to the bottom part 2b of the heat insulating material 2 has an inside diameter R somewhat smaller than the outside diameter W of the bottle B and a small decompressed space S is formed between the bottom part 2b of the heat insulating material 2 and the bottom part B1 of the bottle B by housing the bottle B; and suction and discharge control means X controlling air to get into/out of the decompressed space S. <P>COPYRIGHT: (C)2012,JPO&INPIT |
