ABSTRACT:
This compact lunch box consists of a collapsible carrier body and a collapsible lower casing both having walls made of a thermal insulative material. In the erected state, the lower casing may be removably mounted with a plurality of mounting webs at the bottom side of the carrier body for containing food and beverage. A thermal pack is provided in a well located within the carrier body for maintaining the food and beverage in a low healthy temperature. In the collapsed state, the lower casing can also be conveniently mounted at the bottom of the carrier body to form a compact assembly which can be stored in a briefcase or a school bag.
