Abstract
A dispenser comprising a valved aerosol container and a unitary flexible barrier member having an outer wall segment terminating at a sealing edge, which sealing edge is joined to the container between top and sidewall portions, and an inner wall segment joined to the outer wall segment through a fold and a central piston region emerging from the terminus of the inner wall segment distal to the old. The barrier being sufficiently thick and rigid to be free-standing before incorporation into a pressurized container. The outer and inner wall segments are oppositely-directed frustoconical shapes forming a small acute angle with each other when the barrier is initially inserted into the container. The outer wall segment may be thicker and more rigid than the inner wall segment. The barrier is nestable with like barriers.
