A container of better quality can only slow the temperature of the fluid closer to the external temperature. Speed, but cannot change the temperature of the fluid in a direction opposite to the outside temperature.

Therefore, if the user wants to change the temperature of the fluid in a direction opposite to the external temperature, the user can only cool down by the refrigerator or warm up by the heater. This method of changing the temperature of the fluid not only requires the use of other tools, which causes inconvenience when going out for use. Since the stored fluid needs to be cooled or warmed together, it will also cause waste of energy. When the fluid is stored in the liquid storage space again after the temperature is raised or lowered, it will again face the problem that the temperature gradually approaches the external temperature, so it is known that the container has the above defects when it is used.
