Wrap the cold drink bottle product that is used to maintain a temperature suitable for all beverages, discloses enteric pack. Disclosed packs, with the degree that can wrap the perimeter of the bottle once the product length and the bottle is formed of a size having a width corresponding to approximately half or more of height of the product, space to accommodate a heat transfer material portion pack body; Heat transfer material which is received in the recess of said pack body; And a removable means for holding the state is configured on both sides of the pack body wrap the perimeter of the bottle product. Wherein the heat-conducting substance when onjang tolerated, the sodium acetate is used. This aqueous solution is a built-in elastic body. As the aqueous solution is solidified major surface an impact to an aqueous solution of sodium acetate, using the elastic body to generate heat. This makes it possible to insulate the beverage bottle products. On the other hand, as a heat transfer material, the cold pack is glycerol, polymer and food coloring is added to the aqueous solution, it is used. The aqueous solution is easy, and a low-temperature state, maintains a low temperature for a long time. Thus stored for an extended period of time to drink a bottle of the product to cool.
