Pressurized fluid dispensing apparatus having expansible bladder held in place with compressive forces

摘要

An apparatus for pressurized dispensing of fluid products comprising an elastomeric pressure unit, a support, a sealing member, and a valve and which may additionally include either a container for a housing around the pressure unit or a liner within the pressure unit. The elastomeric pressure unit has an internal cavity which contains the fluid product and also provides the dispensing pressure. An assembly of such an apparatus is obtained without bonded connection and without the requirement of an additional sealing member when a liner is used.
