PROBLEM TO BE SOLVED: To provide a container having a lid body connected to a container body by a hinge, in which closing operation of the lid body is easily and surely performed.SOLUTION: A container 100 comprises: a cylindrical container body 101; and a lid body 111 which is connected to the container body by a hinge 121 and installed to be openable/closable with respect to an aperture of the container body. The lid body includes: a top surface plate 113; and an inner ring which is formed on the top surface plate and fixed to an inner peripheral surface of a lateral wall of the container body in a closed state to seal the container body. In the inner ring, an outer peripheral surface protrusion is formed which protrudes in a circumferential direction of an outer peripheral surface. In the container body, an inner peripheral surface protrusion 103 is formed which protrudes in a circumferential direction of an inner peripheral surface in the vicinity of an edge part of a lateral wall 102. The outer peripheral surface protrusion 114 comes into contact with and gets over the inner peripheral surface protrusion when the lid body is being closed, thereby the lid body is locked to the container body in a state in which the inner ring seals the container body.SELECTED DRAWING: Figure 1 |
