ABSTRACT:
A media dispenser (2) has a discharge head (3), a medium chamber (30) holding a volume of medium filled under pressure, and a hand-operable propellant pump (5). By manual compression of the balloon-like pressure chamber (6) comprising film portions (13, 14), propellant is conveyed into the medium chamber (30), with pressure sufficient to cause the opening of a valve (26), and delivery of a mixture of medium and propellant through an atomizing nozzle (21). The nozzle (21) is tightly closed by a closure (39) connected to a common carrier (40) for a plurality of the dispensers (2). The carrier (40) has interruptible connections to the head (3) which can be interrupted to remove closure 39 and open atomizing nozzle 21.
