Title (EN) IMPROVED AEROSOL CONTAINER CLOSURE
(FR) FERMETURE AMELIOREE DE RECIPIENTS AEROSOLS
Abstract:
(EN) Aerosol dispensing containers have found widespread use in the packaging of fluid materials. Because these containers are maintained under super-atmospheric pressure there has typically been problems with leakage at their mounting cups. The present invention prevents leakage by providing a gasketed mounting cup (10) for an aerosol container having a rigid, substantially non-deformable, annular indent or depression (24) in the outer wall of the channel portion (18) of the mounting cup.
(FR) Les récipients aérosols de dispersion sont largement utilisés dans le conditionnement de matières fluides. Comme ces récipients sont maintenus sous pression superatmosphérique il y a toujours eu des problèmes de fuite au niveau de leur cuvette de montage. La présente invention empêche les fuites au moyen d'une cuvette (10) de montage à joint d'étanchéité, destinée à un récipient aérosol comportant un renfoncement ou une dépression (24) annulaire virtuellement indéformable, située dans la paroi externe de la partie (18) cannelée de la cuvette de montage.
