Abstract: A temperature keeping container includes an inner receptacle and an outer vessel. The inner receptacle is fit in the outer vessel in a tight manner to form an accommodation chamber between the inner receptacle and the outer vessel for receiving and containing a low- or high-temperature medium as desired, or a substance, preferably an edible substance, that is frozen to form a freezing layer, whereby beverage, when deposited in the inner receptacle of the container, can be kept cool to allow a user to enjoy cold beverage of the original flavor, or alternatively, beverage can be poured onto the freezing layer to mix with the substance forming the freezing layer to provide a mixed flavor of beverage.
