A closure cap (10) which can be manipu- lated to dispense container contents and enables venting of any excess pressure which may build up within the container when the closure is in a fully closed position including a central post (12), a cap body (14) reciprocally mounted on and about the periphery of the post and having an aperture (22) including an inner periphery which cooperates with the post to form a variable open- ing therebetween including a fully closed position and a plurality of dispensing positions for dispens- ing the contents of the container at a plurality of different rates and a venting mechanism for en- abling any excess pressure from within the con- tainer to exhaust through the cap to the exterior of the container upon reaching a predetermined pressure within the container when the cap is po- sitioned in the fully closed position.

L'invention concerne un bouchon (10) qui peut être manipulé pour distribuer le contenu du récipient et qui permet l'évacuation de toute pression excédentaire qui pourrait s'accumuler dans le récipient lorsque la fermeture se trouve en position entièrement fermée. Ce bouchon comprend une colonne centrale (12), un corps (14) monté de manière à permettre un mouvement alternatif sur et autour de la périphérie de la colonne et possédant une ouverture (22) comportant une périphérie interne qui coopère avec la colonne afin de former une ouverture variable entre celles-ci. Ce bouchon comprend une position entièrement fermée et une pluralité de positions de distribution afin de distribuer le contenu du récipient à des vitesses différentes ainsi qu'un mécanisme d'évacuation qui facilite la sortie, par le bouchon, de toute pression excédentaire provenant du récipient lorsqu'une pression déterminée est atteinte à l'intérieur de celui-ci, le bouchon étant en position entièrement fermée.
