Container for circular disk-shaped objects

A container for the storage and protection of circular disk-shaped objects, the container comprising a flat (shallow) closure portion having a receptacle to at least partially accommodate a circular disk-shaped object having a center point and a containment portion attached to the closure portion in such a way that the closure portion can be swiveled in and out in order to remove and insert the circular disk-shaped object into the containment portion, and the circular disk-shaped object is completely surrounded by the containment portion and the closure portion when the container is closed, wherein the closure portion comprises an approximately cylinder segment shaped closure sleeve and the containment portion is an approximately square-shaped containment sleeve and the inner contour of the closure sleeve has the same or a slightly larger circular radius and the same or a slightly greater thickness than the circular disk-shaped object, and the outer contour of the closure sleeve has the same or a slightly smaller circular radius than the width of the inner contour of the approximately square-shaped containment sleeve and the same or a slightly smaller thickness than the unobstructed width of the inner contour of the containment sleeve and the closure sleeve is arranged on the containment sleeve and is borne on the latter rotatably and optionally so as to slide, whereby the axis of rotation of the closure sleeve is located vertically on the plane of the circular disk-shaped object and has a separation distance from a centerpoint of the circular disk-shaped object of 1/x of the radius of the circular disk-shaped object, and whereby the axis of rotation can be slid along a guide track whose projection onto the lower surface of the containment sleeve has a length of 1/x of the radius of the circular disk-shaped object and wherein x>1.5.
