With each discharge operation, the volume of the media store S decreases, as a result of which the foil bag contracts.
  • the flexible wall of the film bag thus enables the pressure and volume compensation within the media reservoir S at corresponding Austragsvorêtn the pumping device P.
  • FIGS. 5 and 6 a metering device is shown, the pumping device with the pumping device of FIG. 1 matches. Functionally identical parts of the metering device are provided with the same reference numerals as in the embodiment of FIG. 1, but with the addition of the letter "b". For a more detailed explanation, reference is made to the description of FIG. In the following, only the differences shown in FIGS. 5 and 6 will be discussed in detail.
  • the essential difference is that, similar to the embodiment according to FIGS. 2 to 4, the receiving part 2b is designed separately from a closure lid 1b.
  • the closure lid 1b is designed as a crimp lid, which is placed on a corresponding container neck of a media storage.
  • the placement of the receiving part 2b together with the closure lid 1b designed as a crimp lid takes place with the interposition of an unspecified, circumferential elastic seal.
  • the actuating handle 20b has a cup-shaped protective extension 22b, which is pulled down over the closure lid 1b designed as a crimping lid, so that the protective extension 22b axially covers a crimping region of the closure lid 1b designed as a crimping lid.
  • a release of the closure lid 1b is avoided by a corresponding container neck of a media storage as soon as the actuating handle 20b is snapped onto the outer pump housing part 8b of the pumping device as shown and described in FIG.
  • the separately produced actuating handle is only mounted on the pump housing part 8b when the closure lid 1b is crimped onto a corresponding container neck of a media reservoir. Because with already aufgerasteter actuating handle 22b no crimping would be possible.
