Abstract: A plug-in device system has a closure unit blocking access to a first plug-in device element, for example a socket. The closure unit includes a rotary bezel which is coupled via a coupling to at least one shutter such that the rotation of the bezel effects a movement of the shutter from a closed position in an open position. Preferably, a locking assembly is additionally provided, which blocks movement of the rotary bezel and/or shutter in the closed position as long as no pressure is applied to the shutter. In addition, a safety device can be provided, which prevents the shutter from opening when a direct force is applied.

Abstract: The invention relates to a scaling cap (1) that is to be screwed and/or pressed onto the pouring neck (4) of a container, especially a bottle. Said sealing cap (1) comprises a particularly annular coaxial sealing lip (6) which is fixed within the bottom (2) of the cap and extends into the neck when the cap is mounted. The sealing lip is curved and/or buckled towards the outside between the upper and the lower end (7, 8) thereof in such a way that the curvature (12) and/or the buckled point (9) travel/s further out and the external face of the sealing lip sealingly rests against the interior wall of the neck when the sealing lip is compressed in an axial direction.

Abstract: The invention relates to a sealing/pouring combination with security seal, comprising a sealing cap piece (1), for mounting on a pouring piece (2) with a through passage (3) and for sealing the through passage, whereby the sealing cap piece has a cap circumferential wall (6) and complementary engaging means provided on the sealing cap piece and the pouring piece which come into engagement with each other during the assembly of the sealing cap piece on the pouring piece. The above prevents a movement of the sealing cap piece in a direction against that of the assembly direction. The engaging means on the cap are provided on at least one circumferential wall region (11), recessed in the circumferential wall of the sealing cap piece, connected to the cap circumferential wall with at least a pair of webs (12, 13) in the region of the circumferential ends thereof, of which at least one is embodied as a tear-off web (12).
