Portable device for quick chilling and heating

A liquid cooling and dispensing device, the device comprising:

• an enclosure defining an inner chamber, the enclosure comprising:
• a lower portion having a floor, the floor including a first opening;
• and
• an upper portion having a mouth;
• a closure for covering the mouth, the closure including a liquid reservoir and an opening section, the liquid reservoir having a second opening;
• and
• a conduit extending inside the inner chamber and providing a passage for transporting a liquid between the first opening and the second opening;
• wherein a insulating material can be placed inside the inner chamber and in contact with the conduit, such that when the liquid circulates through the device, the liquid passes from a first temperature to a second temperature lower than the first temperature,
• wherein the entire liquid reservoir is positioned below a horizontal plane defined by a highest point of the opening section, and the liquid can be poured into the liquid reservoir to enter the conduit via the second opening,
• wherein the opening section allows for the addition of the insulating material after the closure engages the enclosure.
