ABSTRACT:
The present invention is a seal for a container closure which is characterized by the fact that associated with the sealing lip (3) is an actuating arm (5) by which the sealing lip can be swiveled. The seal is part of a container closure (1) with a side wall (11) and a bottom (15). When the closure is screwed onto a container, the actuating arm is swiveled counterclockwise, this swivelling movement being facilitated by a deliberate attenuation (17) in the region of the bottom (15) of the closure (1). A counterclockwise swiveling movement of the actuating arm (5) also causes the sealing lip (3) to swivel counterclockwise and thus to lie against the outer wall of the container. A sealing surface is created not only between the container and the actuating arm (5), but also between the outside of the container and the sealing lip (3).
