Abstract
In a container having a lid member coupled to a container body by a hinge, the lid member includes a top surface, an inner ring formed on the top surface, and a projected part is formed on the top surface concentrically with the inner ring and which has an outer peripheral surface provided with an outer peripheral surface projection along the circumferential direction. The container body has a sidewall with a first inner peripheral surface having an inner peripheral surface projection formed along the circumferential direction, and a second inner peripheral surface having an inner diameter different from that of the first inner peripheral surface. When the lid member is closed, the inner ring seals the container body by being fitted to the second inner peripheral surface. The outer peripheral surface projection contacts and slides over the inner peripheral surface projection to lock the lid member the container body.
