ABSTRACT:
A packaging case includes a case body for storing a wrap film and a lid continuously formed with the top edge portion of a rear wall of the case body. Flap pieces extend outward to be pivotal on the top edge portions of side walls of the case body. Stepped portions engaged with the flap pieces to prevent floating of the lid are formed on the inner surfaces of lid side walls covered on the side walls of the main body during closing of the lid. Predetermined portions of the side walls of the main body continuous with the flap pieces are made thinner than remaining portions of the side walls. The inner surfaces of the remaining portions are located inside the inner surfaces of the predetermined portions.
