Abstract

A dispenser for flowable media is constructed as a disposable atomizer, whose entire media reservoir is formed by the pump chamber of a thrust piston pump. The freely exposed cylindrical container constructed as a push button-like handle is therefore valve-free and can only be opened towards the outlet duct.
