ABSTRACT A closure cap (1) of plastics material has a circular sealing lip (5) which is arranged in the region of the join (6) between the cap wall portion (3) and the cap end portion (4), and points inwardly at an inclined angle. At its smallest diameter, the sealing lip has a rounded sealing portion (7). Below the sealing portion, the sealing lip is enlarged outwardly in a funnel-like configuration, to receive the mouth (2) of a container. By virtue of that arrangement, a reliable sealing action is produced at the outside wall portion (8) of the mouth (2) of the container, even when there are large fluctuations in tolerances. In each case, the sealing region which extends circularly around the mouth of the container is of a linear configuration, which considerably enhances the sealing action of the sealing lip.
