An inner frame forming a part of the body has a tongue, and an engagement area positioned in the proximity of an open edge of the lid and engaging with the tongue is provided to an inner front flap of the lid. This engagement area is formed by cutting off the inner front flap. When the lid is closed, the tongue is inserted between the inner surface of the lid and an engagement plate.
