Several length-cut pipe shaped cooling units (100) are removably combined each other, and hollow spaces are formed inside of the above mentioned cooling units for filling in refrigerant. Also, the cooling units can be combined each other to make a pipe-shaped form to keep cooling a cup or a bottle by surrounding it.</p> |
