Abstract (en)
[origin: WO9602439A1] 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).
