Title
(EN) FLEXIBLE BARRIER MEMBER USEFUL IN AEROSOL DISPENSERS
(FR) ELEMENT DE BARRIERE FLEXIBLE UTILE POUR LES BOMBES AEROSOL
Abstract
(EN)
A dispenser comprising a valved aerosol container (22) and a unitary flexible barrier member (10) having an outer wall segment (12) terminating in a sealing flange (16). The sealing flange (16) is joined to the container (22) between top and sidewall portions (27, 25), and an inner wall segment (14) is joined to the outer wall segment (12) through a fold (15). A central piston region (20) emerges from the terminus of the inner wall segment (14) distal to the fold (15). The barrier (10) is sufficiently thick and rigid to be free-standing before incorporation into a pressurized container (22). The outer and inner wall segments (12, 14) are oppositely-directed frustoconical shapes forming an acute angle with each other when the barrier (10) is initially inserted into the container (22). The outer wall segment (12) is thicker and more rigid than the inner wall segment (14). The barrier (10) is nestable with like barriers (10).
(FR)
Une bombe aérosol comprend un récipient (22) muni d'une vanne pour aérosol et un élément unitaire (10) flexible constituant une barrière et ayant un segment externe (12) de paroi se terminant par une bride d'étanchéité (16). La bride d'étanchéité (16) est réunie au récipient (22) entre une portion de paroi supérieure (27) et une portion de paroi latérale (25), et un segment interne (14) de paroi est réuni au segment externe (12) de paroi par un pli (15). Une région centrale (20) en forme de piston termine le segment interne (14) de paroi à l'extrémité opposée à celle du pli (15). La barrière (10) est suffisamment épaisse et rigide pour tenir debout toute seule, avant son introduction dans le récipient (22) sous pression. Les segments externe (12) et interne (14) de paroi ont la forme de sections de cônes orientés en sens opposés et ils forment l'un avec l'autre un angle aigu lorsque la barrière (10) est installée initialement dans le récipient (22). Le segment externe (12) de paroi est plus épais et plus rigide que le segment interne (14) de paroi. La barrière (10) peut s'emboîter dans d'autres barrières (10) similaires.
