Disclosed is a heating food tray for child. The heating food tray for child according to the embodiments of the present invention is provided with a heat generation unit to provide a function of heating food contained in the food tray or keeping a temperature of the food. In addition, the embodiments of the present invention provides the heating food tray including the control unit to execute or stop the heating or heat-keeping function when the temperature deviates from a preset value.

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.

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.

A lid may be for a temperature-conserving container and may include a bottom wall, a side wall formed around a perimeter of the bottom wall, and a top wall connected to the side wall. An insulative cavity may be between the top wall and the bottom wall, and the insulative cavity may be configured to reduce heat transfer through the lid. A lip may be formed around at least a portion of an outer surface of the side wall or the top wall. The lid may be configured to be slidably received in an opening of the temperature-conserving container such that at least a portion of the lip engages a top rim of the opening and forms a seal between the outer surface of the side wall and the inner surface of the opening, thereby sealing the temperature-conserving container.

A drinking vessel has a sidewall formed of multiple structured layers. The sidewall includes an open spout and a closed base. A circumference of the side wall at the base is larger than a circumference of the side wall at the open spout to provide the drinking vessel with a lowered center of gravity than a traditional drinking vessel with the closed base narrower than the open spout. The sidewall includes multiple structured layers to form a scaffold structure.

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.

A dish assembly for serving food includes a dish housing that defines a surface, upon which the food can be placed, and an inner compartment, a phase-change material within the inner compartment, and an electrically-conductive element inside the inner compartment and thermally coupled to the phase-change material. In a typical implementation, the phase-change material is adapted to melt in response to the electrically-conductive element being heated by an electromagnetic induction heater. The thus heated dish assembly can facilitate getting hot food to a table while it is still hot, and once at the table, keeping that hot food at least warm for quite some time, while it is consumed.

An improved temperature regulating dinnerware set is a dinnerware set with each dinnerware piece having a heating element and a control member for controlling the temperature of the top surface of the piece. Each piece is adapted to connect to a power source to control the embedded heating element. An attachable cover is provided for each piece of the dinnerware set to help maintain the temperature.

An actively heated mug, travel mug, baby bottle, water bottle or liquid container is provided. The mug, travel mug, baby bottle, water bottle or liquid container can include a body that receives a liquid therein and a heating or cooling system at least partially disposed in the body. The heating or cooling system can include one or more heating or cooling elements that heat a surface of the receiving portion of the body and one or more energy storage devices. The mug, travel mug, baby bottle, water bottle or liquid container can include a wireless power receiver that wirelessly receives power from a power source and control circuitry configured to charge one or more power storage elements and to control the delivery of electricity from the one or more power storage elements to the one or more heating or cooling elements. The mug, travel mug, baby bottle, water bottle or liquid container also can have one or more sensors that sense a parameter of the liquid or sense a parameter of the heating or cooling system and communicates the sensed information to the control circuitry. The control circuitry can turn on, turn off, and/or operate the heating or cooling element to actively heat or cool at least a portion of the body to maintain the liquid in a heated or cooled state generally at a user selected temperature setting based at least in part on the sensed parameter information. The mug, travel mug, baby bottle, water bottle or liquid container can also be paired with a remote device or mobile electronic device to send or receive communications or commands.

A food delivery apparatus includes a domed shell that defines an interior space. A thermal storage device is secured to the shell so as to direct heat downward to food within the interior space.
