A cup for cooling and maintaining cooling is provided to cool a beverage promptly, and to maintain the cooled state of the beverage by using various refrigerants that are not harmful to a human body. A cup for cooling and maintaining cooling includes an inner cup(10), a middle cup(20), a refrigerant(R), an outer cup(30) and a lower cover(40). A receiving space is installed on the middle cup(20) made of a thermal conductor. The refrigerant(R) is received into the receiving space. The outer cover(30) is mounted on the middle cup to intercept loss of latent heat of the refrigerant. The lower cover(40) is detachably coupled to the outer cup(30) with a coupling unit(C) to open and close the receiving space into which the refrigerant(R) is received. |
