ABSTRACT:
A closure device for a container is described consisting of a cap for a container and a cap lid which is pivotably mounted on the cap. The cap lid has an encircling circumferential border which projects downwardly from the upper surface of the lid. The border is a curved spherical surface segment and the cap defines a cup-shaped recess which is complementary in shape to facilitate sealing. The center of curvature of the spherical surface segment is located on the pivot axis of the cap lid. A pair of supporting plates are formed on a base portion of the cap and are guided in the pivot plane of the cap lid by parallel guide ribs so that the cap is non-rotatably mounted and pivotably mounted reliably in the recess and is sealed in every operating position relative to the container cap.
