PROBLEM TO BE SOLVED: To provide a pet bottle cooler improving cooling efficiency as a cooler for pet bottle exclusive use and functioned as a cold insulator even when a power source for cooling can not be secured being a small type and excellent in portability. SOLUTION: The pet bottle cooler comprises upper and lower cases 2 and 3 being cases to contain a pet bottle 1; an upper part heat transfer body 2a disposed in the upper case 2 to transfer cold air; a lower part heat transfer body 3a disposed in the lower case 3; a first bottom cover 4 of the case; and a second bottom cover 5 to cool the pet bottle 1. In a state that a power source can be used, it is used as a cooler and when a power source can not be used or cooling is completed, the second bottom cover 5 of the pet bottle cooler is removed, the first bottom cover 4 is mounted in stead of the second bottom cover and it is used as a cold insulator. Further, structure is provided to separate the upper part heat transfer body 2a and the lower part heat transfer body 3a from each other, partial cooling is practicable.
