PURPOSE:To respectively facilitate the opening/closing of a lid and the detaching of the lid from a container main body, and at the same time, simplify the structure, and facilitate the manufacture by a method wherein a notch part for connection and a protruding piece for connection are fitted under a condition wherein fitting protuberances are fitted in recessed parts, and the lid is rotatably and openably attached to the container main body. CONSTITUTION:The major part of a container is constituted of a container main body 1 and lid 2 made of an expanded synthetic resin. In this case, the container main body 1 is formed into a shape wherein the top is open, and at the same time, a lid plate 7 to close the opening is arranged on the lid 2. Also, on either one of the upper end of one side wall of the container main body 1 and one side end of the lid plate 7 corresponding with said upper end of one side wall, notch parts 4 for connection are formed, and protruding piece 8 for connection are formed on the other part respectively. In addition, rotatable protuberances 12 are formed on either one of both side internal surfaces of the notch part 4 for connection and both side external surfaces of the protruding piece 8 for connection, and recessed parts 13 are formed on the other parts respectively. Then, under a condition wherein the fitting protuberances 12 are fitted in the recessed parts 13, the notch parts 4 for connection and protruding pieces 8 for connection are fitted. By doing so, the lid 2 is rotatably and openably attached to the container main body 1. |
