In the embodiment of the present invention, the box body 100 may be a cylinder or a rectangular parallelepiped, and the interior thereof is hollow and has only an opening on the top surface for storing and taking articles. It is possible that the case 100 is blow molded from a plastic material such as polypropylene, or made from a glass material to facilitate observation of the number of stored items at any time, or made from a metal material such as stainless steel. The upper cover body 200 is installed on the outer side wall of the outlet of the box body 100 and is hinged through a positioning shaft, so that the upper cover body 200 can be turned over by 90 degrees, and the opening and closing of the upper cover body 200 and the box body 100 are realized. The push-out mechanism 500 connects the upper cover 200 and the lower cover 400, and controls the upper cover 200 and the lower cover 400 to approach and separate from each other. The fixing portion of the ejection mechanism 500, that is, the end fixed to the upper cover 200, may be a hollow cylinder, and the cylinder may be integrally formed with the upper cover 200, or may be fixed to the upper cover 200 by screws or the like. The movable part of the ejection mechanism 500 is mounted in the cavity of the cylinder, and the movable part can slide up and down in the cavity of the cylinder. In addition, the movable portion of the ejection mechanism 500 is detachably connected to the lower cover 400, for example, the movable portion and the lower cover 400 are provided with a protrusion and a groove which are matched with each other, and are fixed by rotation engagement or press engagement. The sealing ring 410 may be made of a silicone material, and is sleeved on the lower cover 400 and can be detached and replaced by hand. The pivot 610 of the connecting rod 600 may be a rod-shaped supporting seat separately set on the upper cover body 200, or may be directly set on a fixing portion of the ejection mechanism 500, for example, a cylindrical small protrusion is set on the outer side wall of the aforementioned cylinder, and a through hole or a groove corresponding to the small protrusion is set on a lever arm of the connecting rod 600, so as to implement the rotational connection between the connecting rod 600 and the upper cover body 200, around which the connecting rod 600 rotates. One end of link 600 abuts key assembly 300, and the other end is connected to the movable portion of ejection mechanism 500. When key assembly 300 is pressed to a limit state, connecting rod 600 is pressed, and through lever steering force, the movable portion of ejection mechanism 500 is driven to move upward, i.e. to move toward the direction close to upper cover 200, lower cover 400 is driven by the movable portion of ejection mechanism 500 to also move toward the direction close to upper cover 200, and sealing ring 410 arranged on lower cover 400 and the inner wall of box 100 are relatively displaced and deformed, so that sealing ring 410 is tightly attached to the inner wall of box 100, thereby achieving a good sealing effect.
