PROBLEM TO BE SOLVED: To provide a one-touch openable/closable container that is obtained by forming a material such as a paper plate into the shape of a headstand pinnacle, firmly seals one large-diameter open end by a simple operation, can also be unsealed by a simple operation when opened, has a stable reseal, and excels in the protection of an accommodated commodity. SOLUTION: The container includes a peripheral wall in the form of a headstand pinnacle. The intersection of an imaginary end edge line and imaginary dividing lines on both sides of it is assumed as an end edge vertex. Also, the intersection of an imaginary shoulder line, end edges on both sides of it, and a central imaginary dividing line is assumed as a shoulder bend point, and adjacent intersections are connected by valley folds. Fold superposition plates adjacently formed by bisecting a mountain fold between opposing valley folds on the shoulder bend point are folded and superposed, thereby forming a cross-shaped sealing portion where the peripheral open ends are joined. A lockable plate extended in a direction opposite to a folded plate extending to the upper end of one of the opposing connected fold superposition plates and folded inside is fitted and locked in a fold superposition part formed by folding the fold plate and the other one of the opposing fold superposition plates.
