The present invention provides a cooling device, comprising a first cooling portion, a second cooling portion, and a first receiving cavity sandwiched between the first cooling portion and the second cooling portion, where the first cooling portion is disposed around the second cooling portion, and the first cooling portion and the second cooling portion are distributed spaced-apart. According to the present invention, the liquid to be cooled in the first receiving cavity is simultaneously cooled by the first cooling portion and the second cooling portion without an additive being added, so that the cooling effect is substantially improved.

Provided is a tumbler capable of controlling a temperature of an accommodated drink. The tumbler includes an inner cup for accommodating a drink, a frame which protects the inner cup, a heat conduction unit of which heat is exchanged with the inner cup through a lower surface and an outer circumferential surface of the inner cup to cool or heat the drink of the inner cup, and a control unit configured to control operation of the heat conduction unit. The thermal efficiency and ease of use of the tumbler are improved due to the configuration of the tumbler.

Apparatus for controlling the temperature of a beverage container, for example, by either chilling the beverage container or maintaining the beverage container at a predetermined temperature, the apparatus having a generally cylindrical configuration with a receptacle in its upper portion and cooling components in the lower portion to establish a low center of gravity for the apparatus.

An actively heated or cooled mug has a body with a chamber that can receive and hold a beverage and a heating or cooling system disposed at least partially in a cavity below the chamber. The heating or cooling system has a heating or cooling element to actively heat or cool the chamber, power storage devices, and circuitry that controls the operation of the heating or cooling elements. A user interface is electrically connected to the circuitry and has one or more selection members actuatable a) to turn off the one or more heating or cooling element or b) to adjust a temperature setting to one of multiple temperature settings configured to control the one or more heating or cooling elements to heat or maintain the liquid at a user selected temperature.

Disclosed herein are systems for controlling and maintaining the temperature of a drink. The system may include a receptacle defining a recess for receiving a drinking vessel. The system may have a stand for holding the receptacle upright. The stand may be releasably attached to the receptacle. The receptacle may include a top end portion, a bottom end portion, an inner wall portion, and an outer wall portion. The top end portion may define a top opening of the recess. A system may include a first receptacle defining a first recess for receiving a drinking vessel. The system may include a second receptacle for receiving a drinking vessel, wherein the second receptacle defines a second recess. The system may include a first stand operable to releasably attach to the first receptacle and the second receptacle. Also disclosed are methods for controlling and maintaining the temperature of a drink.

An actively heated or cooled cup or mug has a body with a chamber that can receive and hold a beverage and a heating or cooling system disposed in a cavity below the chamber. The heating or cooling system has a heating or cooling element to actively heat or cool the chamber, power storage devices, and circuitry that controls the operation of the heating or cooling elements. A sensor can detect a presence of a liquid in the chamber, the circuitry configured to turn on power to the heating or cooling elements after said liquid is detected and further configured to automatically turn off power to the heating or cooling elements upon receiving a signal indicating that the liquid in the chamber has dropped below a predetermined liquid level or been depleted completely.

Disclosed is a drinking cup including a cup body and a cup bottom. The cup bottom is connected to one side of the cup body, the cup bottom and the cup body enclose a water-holding cavity with an opening opposite to the cup bottom, the water-holding cavity is configured for holding liquid drinks, the cup bottom is protruded toward the water-holding cavity to form a temperature regulating portion. The temperature regulating portion has a temperature regulating cavity inside, and the temperature regulating cavity is filled with heat exchange substances, to exchange heat with the liquid drinks. The present application solves the technical problem that the existing water cup cannot adjust the water temperature.

A mechanical apparatus comprised of a plurality of pods in the form of a cylindrical sleeve, containing liquid, to be frozen for the purpose of dynamically transfer/impart its charged thermal energy to a directly contacted object placed within. The pods are joined to each other by elastic bands allowing it to instantly expanse and grip varying size beverage containers. Furthermore, the plurality of pods and a beverage container are disposed in an insulated holder; a sealable cap is then inserted to seal off and insulate the discharging of thermal energy therein from ambient conditions. A beverage in the form of can or bottle may be placed in the apparatus to achieve desired chill temperature for an extended length of time in high ambient temperature conditions.

The present invention comprises a novel liquid temperature controlled mug which also allows controlling temperature in disposable cup. The temperature controlled mug is capable of maintaining temperature over wide temperature range. Voice activated temperature control with contact type battery charging makes the temperature control cup easy to handle.

An actively heated or cooled food container can have a lid movable between an open and a closed position and an insulated body to which the lid can be attached. The insulated body can have a sidewall that defines a perimeter of the container body and a base, the sidewall and base defining one or more chambers that can be sealed by the lid. The food container can have a temperature control system that can include one or more heating or cooling elements in thermal communication with one or both of the sidewall and the base and operable to heat or cool one or both of the sidewall and the base to thereby heat or cool the one or more chambers in the food container.
