A container for holding contents as two separate components which can be mixed together later. The container comprises a cup positioned in a neck of the container for receiving a first of the components; a screwcap coordinated with the neck of the container and having a collar extending into the cup, a front edge of said collar forming a strike edge for separating the cup in the region of a line of intended breakage upon a further screwing on of the screwcap beyond a basic position for storage; and a wall of the cup has an annular step, and the strike edge of the collar comes flush on the annular step on the wall of the cup, the step--forming the place of intended breakage--being located at a distance above the bottom of the cup, there being a bead extending towards an outer surface of the collar and projecting inwardly from the inner surface of the wall of the cup, the step lying below said bead; and a clip shoulder is disposed on the collar and engages the bead of the cup wall.
