An actively heated drinkware container includes a vessel with a chamber that receives and holds a volume of liquid. The drinkware container includes a heating module with a first heating element operable to heat one portion of the chamber and a second heating element operable to heat another portion of the chamber, the second heating element spaced from the first heating element. Operation of the first and second heating elements generates a circulation current in the volume of liquid in the chamber that mixes the liquid and diffuses a temperature of the liquid to thereby reduce temperature stratification of the liquid in the chamber and so that a temperature of the liquid throughout the volume of liquid in the chamber is approximately uniform.

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.

An actively heated mug has a body with a chamber that can receive and hold a beverage and a heating element to actively heat the chamber, batteries, and circuitry that controls the operation of the heating element. A user interface is electrically connected to the circuitry and has one or more buttons actuatable a) to turn on the heating element, b) to adjust a temperature setting to one of multiple temperature settings to control the operation of the heating element to heat or maintain the liquid at a user selected temperature setting, and c) to turn off the heating element.

The disclosure relates to a tea drinking vacuum flask with a tea-making function, which relates to the field of drinkware and is used for optimizing the structures of drinking utensils. The tea drinking vacuum flask with a tea-making function comprises a lid body, a connecting piece, a filtering element, and a liquid containing body. The lid body comprises a first end and a second end arranged opposite to the first end; the connecting piece comprises a channel, and the channel comprises a first connection end and a second connection end; and the first connection end is detachably connected with the second end. The tea drinking vacuum flask with a tea-making function of the technical solution avoids the formation of vacuum in the tea drinking vacuum flask and can ensure the filtering effect.
