NOVELTY - The utility model relates to a container, specifically to a container for fast cooling and constant temperature. comprising a bottom wall and a side wall surrounding the top part of the bottom wall, the surrounding back side wall and the bottom wall form a containing cavity, the side wall and the bottom wall comprise a shell and an inner shell, the side wall and the shell corresponding to the bottom wall are fixedly connected to form an inner wall of the containing cavity, the inner shell corresponding to the side wall and the bottom wall is fixedly connected to form an outer wall for containing the cavity; a constant temperature cavity is formed between the inner wall and the outer wall; the constant temperature cavity is provided with a phase change constant temperature layer. In the utility model, iron, aluminium, graphene, stainless steel and so on metal material as the heat conducting layer, the phase change constant temperature ball is cooling material, the fast heat absorption constant temperature of the phase change constant temperature ball reaches the purpose, the 100 degrees of liquid temperature reducing to 40-80 degrees centigrade can be acceptable inlet temperature, so as to solve the problem that the cooling is too slow to cause long time cannot be drunk. .
