The premise of the device's operation is employing the Peltier Effectusing thermoelectric coolersto keep smaller amounts of consumable liquids or food either cold or hot during short distances of travel. The device is a portable metal container with an inner container encompassed by an outer container to provide an insulation moat that aids in maintaining a level interior temperature. The inner container has adhered cascaded thermoelectric coolerspowered by a rechargeable battery (or batteries) using on-board inductive and photovoltaic charging systemsthat are equidistance apart. The adhered thermoelectric coolersdepending on the configurationextract heat from or add heat to the interior of the inner container, resulting in a cooler or hotter temperature respectively. The resulting effect is that consumable liquids or food are made or kept cool or warm.

A portable drink holder for a drinkable liquid having a first removable reservoir for storing the liquid at a first end of the holder, a second removable reservoir at a second end of the holder for receiving the liquid and a cooling cartridge having a plurality of passageways for selectively transporting liquid from the first reservoir to the second reservoir. The cooling cartridge including a cooling medium so that the liquid transitions to a second temperature lower than the first temperature as it flows from the first reservoir to the second reservoir.

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.

Quite often it is heard that people complain about having cold food at their places of work. The problem is not localized to a particular geographic area or age, it affects everyone who prefers having hot food at workplace or college. The Smart Lunch box aims at providing hot food to users anytime and anywhere they want. It uses heating elements along with microcontrollers powered by batteries to provide heat even in the absence of a power outlet. The batteries have to be sufficiently charged well before hand, the box can be controlled to set temperatures and timer through a mobile application which simplifies the user interface and also reduces human intervention. The box can also be used as a noodle maker by using hot water. The technical applications are immense. This invention can be of great help to various working sects of the society.

Embodiments of the present disclosure relate to a system and method for holding food products within a vehicle. An example system includes a basin configured to receive food products and comprising at least one channel. The at least one channel may be configured to receive at least one divider to segment the basin into at least a first chamber and a second chamber. The system may further include a door configured to transition between a first state and a second state to expose the basin. The system may further include at least one environment regulation system configured to actively control at least one environmental condition within at least one of the chambers.

A portable heated lunch box comprises a housing, an intermediate housing, a liner, a battery, a heating tube, a heat-conducting plate, a temperature sensing module and a control module. The intermediate housing is sleeved inside the housing, and the liner is sleeved inside the intermediate housing; the battery, the heating tube and the heat-conducting plate are arranged between the bottoms of the housing and the intermediate housing, the heat-conducting plate fits with the bottom of the intermediate housing, the heating tube comes in contact with the heat-conducting plate for heat conduction, and the battery, the heating tube and the temperature sensing module are electrically connected to the control module. The internal components are compactly arranged, and external power supply is not required for heating. The temperature sensing module is close to the heating area. A display module ensures intuitive monitoring of heating temperature, remaining battery level and heating duration.
