  • the invention is also based on the object of avoiding disadvantages of known discharge devices and, in particular, of creating a discharge device which, with the simplest possible construction, ensures simple assembly, high conveying capacity, low space requirements and good adaptation to different further discharge units.
  • the features of claim 1 are suitable for achieving this object.
  • the holder for connection to the further discharge unit expediently lies at least partially within the pressure space, wherein it is used for holding engagement in a base body and / or in a component of the further discharge unit that can be moved relative to this, for example for the discharge, can be formed.
  • the holder is expediently arranged rigidly with respect to the area of the pressure chamber adjoining it and / or with respect to a basic body delimiting it, so that it can form a one-piece component with this basic body, with respect to which another component can be moved manually for discharge actuation. If the discharge device has a plurality of pressure spaces or if it is provided for conveying from different storage spaces for media, two or more holders of the type described can also be provided.
