PROBLEM TO BE SOLVED: To easily cool drinking liquid by the heat of evaporation at the time of ejection of the liquefied gas, by forming a projection at the outside of a cooling container attached to a drink container, in which the liquefied gas is charged, and boring a small hole in the cooling container by breaking the projection. ;SOLUTION: This drink container 4 is once turned upside down before it is opened, on having the drink 6 and the projection 3 of a cooling container 1 which is contained in a recess 7 at the bottom of the drink container 4, is broken by fingers to open a small hole on the cooling container 1. Then, the liquefied gas in the unsealed cooling container 1 is evaporated and ejected to the outside. In this time, the gas absorbs the heat of evaporation and hence, the cooling container is abruptly cooled and the drink 6 is also cooled. Since the drink container 4 is turned upside down, even if the contact area of the drink 6 and the cooling container 1 is small, convection of the drink 6 is brought and hence, the drink is sufficiently cooled.;COPYRIGHT: (C)1997,JPO
