Thermal container with quick-release lid-mounted flask

A container for maintaining the temperature of the contents placed therein comprising

• a body having a locking lip formed integrally thereof and a cavity for holding the contents,
• a lid pivotally secured to the body for closing the cavity of the body, said lid having
• a first end,
• a second end,
• a top,
• an underside,
• a bore therethrough,
• a holding means on the first end on the underside of the lid for supporting the flask in position,
• an open chamber formed integrally of the underside thereof,
• a flask for holding a thermal material which is heated or cooled as desired to maintain a hot or cold temperature in the cavity, said flask secured in the open chamber of the lid, said flask having a circular stub formed integrally thereof, and
• a locking means mounted on the lid for locking the lid and the body together and for releasably securing the flask in position on the underside of the lid, said locking means including
• a circular body member having a first side and a second side,
• a shaft formed integrally of the circular body member extending from the first side, the shaft having
• a partial cylinder support wherein rotation of the circular body member will allow the partial cylinder support to alternately support and release the stub, and
• surfaces on the locking mechanism which coact with the locking lip for limiting the rotation of the locking means in either direction and for preventing the release of the flask when the lid is closed, the surfaces including a first shoulder and a second shoulder.
