• wherein the container bottom portion and the container cover portion are hinged to the ridge member, the container bottom portion and the container cover portion form a sealed container body with the ridge member, and the tray is configured to hold the sheet-like object;
• wherein the container bottom portion is provided with a pair of articulated shaft-receiving bases, the tray is connected to the pair of articulated shaft-receiving bases through an articulated shaft provided on the tray, so that the tray is turned over around the articulated shaft-receiving bases, an inner space for self-adaptive rotation and shock absorption of the articulated shaft is formed in the articulated shaft-receiving base,
• wherein the articulated shaft-receiving bases comprises a connecting piece and a pair of limiting walls, a lower end of the limiting walls is connected to the container bottom portion, and an upper end of the limiting walls is provided with hook-shaped members which are opposite to each other, the connecting piece is provided between the pair of limiting walls and is an arc-shaped piece curved upwards, the articulated shaft is provided with a pair of protruding portions with column shape in axial direction thereof, a longitudinal length of the articulated shaft between the pair of protruding portions is configured to correspond to the articulated shaft-receiving base, and the connecting piece is respectively connected with each of the pair of the limiting walls to form an inner space for accommodating the longitudinal length of the articulated shaft with the limiting walls,
• wherein a gap is provided between the hook-shaped members of the pair of limiting walls, the longitudinal length of the articulated shaft between the pair of protruding portions is able to be inserted between the pair of limiting walls through the gap between the hook-shaped members;
• wherein the connecting piece is respectively connected with each of the pair of the limiting walls to form the inner space for accommodating the longitudinal length with the limiting walls, wherein, the longitudinal length of the articulated shaft between the pair of protruding portions is able to be adaptable with the arc-shaped structure of the connecting piece so as to move along the arc-shaped structure of the connecting piece when the tray is turned over, and the longitudinal length of the articulated shaft is kept contacting with the connecting piece so as to be supported,
• wherein the diameter of the pair of protruding portions is greater than the largest lateral width of the limiting walls.
