Abstract

A container includes a body and a cap closed on the body. The body has an open upper side, a bottom and four side walls, which have the circumference of the upper opening provided with an outer circumferential edge and an inner circumferential edge, and a circumferential groove between the outer circumferential edge and the circumferential inner edge for combining with the cap. The inner circumferential edge has a protruding edge, and two hooking projections on the outer circumferential edge. The circumferential groove is provided with a curved combining surface, and there is a combining groove between the outer circumferential edge and the curved combining surface. The cap is closed on the body, having an inner circumferential edge and an outer circumferential edge, and a protruding edge and a bent edge formed in an inner side of the outer circumferential edge. Then when the cap is combined with the body, the circumference between the outer and the inner circumference of the cap fits with the inner circumferential edge of the body, sand the protruding edge of the inner circumferential edge of the body fits with the protruding edge of the outer circumferential edge of the cap. So the bent edge of the outer circumference of the cap slides down along the curved combining surface to it place, finishing the closing the cap on the body. In opening the cap from the body, the booking projections of the body should be released, making up the safe sealing of the container.
