Abstract
A sleeve box including a sleeve with a base, opposite sides, and a connecting handle over the base. At least one of the opposite sides of the sleeve has a locking tab. The sleeve box further includes a lower pan having an out turned flange forming a groove. An upper dome cover is fitted over the lower pan to form a food container. The sleeve is fitted around the food container with the locking tab fitted restrictively into the lower pan, thereby assisting to secure the food container within the sleeve. The sleeve has a vent aligned with a vent in the upper dome cover to allow heat to escape from the interior of the container.
