PROBLEM TO BE SOLVED: To provide a cooler box wherein a paper pack filled with a liquid is prevented from being inclined and falling and the storage space inside of a casing can be used effectively. SOLUTION: The upper first door 7a is fixed to a position capable of positioning the door 7a approximately in parallel with a side-wall 2c when the door 7a is swung from a side-wall 2d, the second door 8 is fixed to a position capable of positioning the door 8 approximately in parallel with the wall side 2d when the door 8 is swung from the first door 7a, and a space capable of containing the paper pack 14 is defined by the four faces of the first door 7a, the second door 8, the side-wall 2c and the side-wall 2d. A cap member 11 used to seal the inside of the paper pack 14 is held on the upper end portion of the paper pack 14 contained in the storage space. Accordingly, even though the box cooler is carried and shaken, the paper pack 14 can be prevented from being inclined and falling and the liquid can be prevented from flowing out from the inside of the paper pack 14. Moreover, since each of the doors can be contained in the side-wall 2d, the inside of the casing can be used effectively. COPYRIGHT: (C)2006,JPO&NCIPI
