CA 2472769

The invention relates to a pressure pack aerosol can comprised of a body blank (2), of a dome (3) for accommodating a valve (4), of an inwardly arched bottom (5), of an inner sleeve (7), which is arranged on a disk (6), and of a tappet (9), which is arranged inside the inner sleeve (7), which is provided for splitting open said inner sleeve (7) and which can be displaced therethrough by the disk (6). According to the invention, the inner sleeve (7) is joined to the disk (6) via a spring cage (11), and the spring cage (11) contains a release mechanism (12), which is spring-mounted and which acts upon the tappet (9). Said tappet (9), in turn, acts upon a cover (8), which is arranged on the can-side end of the inner sleeve (7), and splits the cover open when actuated. A diaphragm (15) is arranged between the tappet (9) and the release mechanism (12) and hermetically seals the inner sleeve (7), on its disk-side end, off from the contents of the pressure pack aerosol can (1).

La présente invention concerne un récipient sous pression comprenant un corps de récipient (2), un dôme (3), qui accueille une valve (4), un fond voûté (5), une gaine interne (7), qui est montée sur un plateau (6), ainsi qu'un poussoir (9), qui est monté dans ladite gaine interne (7), qui force l'ouverture de la gaine interne (7) et qui peut être actionné à travers cette gaine interne par l'intermédiaire du plateau (6). Selon cette invention, la gaine interne (7) est connectée au plateau (6) par l'intermédiaire d'une cage à ressort (11) qui comprend un mécanisme de déclenchement (12) monté sur ressort, agissant sur le poussoir (9). Ce poussoir (9) agit à son tour sur un couvercle (8) qui est monté à l'extrémité côté récipient de la gaine interne (7) et dont l'ouverture est forcée lorsque le poussoir est actionné. Une membrane (15) se trouvant entre le poussoir (9) et le mécanisme de déclenchement (12) ferme la gaine interne (7) à son extrémité côté plateau de manière hermétique par rapport au contenu du récipient sous pression (1).
