Abstract
This invention relates to a packaging and distribution assembly (10) for a fluid product, of the type comprising: a storage member (22), comprising a tubular reservoir (40) able to receive a first fluid composition; a closed chamber (130) in communication with the tubular reservoir; and a pressurization member (24), able to move axially in such a way as to decrease a volume of said closed chamber. The closed chamber is sealed from the air in a deployed configuration of the storage and pressurization members, corresponding to a maximum volume of the closed chamber.The storage member (22) and the pressurization member (24) comprise means (76) for breaking the seal of the closed chamber in a compact configuration of said storage and pressurization members, said compact configuration corresponding to a minimum volume of the closed chamber.
