A discharge device for a liquid medium includes a storage container for receiving a medium, a discharge head which can be secured on the storage container and comprises a discharge opening for discharging the medium out of the storage container, an outlet valve which is paired with the discharge opening and comprises a pretensioned valve element that delimits a valve pre-chamber by means of a pressure application surface formed on a membrane. The pressure application surface has a stationary clamping region on the outside, and a pressure equalization channel which opens into the storage container and comprises a filter assembly that operates microbiologically and is inserted into the pressure equalization channel. The pressure equalization channel is separated from a medium path from the storage container to the discharge opening via the valve pre-chamber, and the pressure application surface has a cap-like edge protrusion as a clamping region which can be placed on a plate edge of the inner component of the discharge head on the inside. The plate edge has a stop that extends outward radially and forms a support surface for the edge protrusion while being spaced from the pressure application surface by a head surface of the plate edge.

Dispenser for a liquid

One aspect of the invention provides a componentfor a fluid dispenserwhich defines a dosing chamberfor a piston memberto stroke in and has an endadapted for engaging a fluid outletof the fluid dispenser or a sealwhich overlies the fluid outletto selectively close and open the fluid outletor seal. Other aspects are disclosed herein.

Fluid dispenser

Dispenser () for the dosed dispensing of liquid media, with a container () for holding a liquid medium (), a manually actuated pump (), which is arranged on the container () and comprises a flood chamber () into which liquid medium () flows when the container () is turned over, for which purpose the flood chamber () is fluidically connected at the inlet end to an outlet opening () of the container (), and a dosing piston (), which is displaceable by an actuating stroke, is arranged in the flood chamber () and expels dosed medium (), and a media channel () extending through the dosing piston () is widened at the inlet end as a volumetrically defined cylinder portion () into which a plunger piston () protruding into the flood chamber () engages as a pressure piston in order to expel medium () introduced by gravity into the cylinder portion () of the dosing piston ().

Other aspects are disclosed herein.

A discharge head for fluids, with a discharge nozzle () which has a discharge opening () and accommodates an internal sleeve () in which is arranged an internal body () which delimits an outlet channel () and has a connecting element () for connection to a counterpart () of a discharging apparatus, the internal sleeve () having, on the end side adjacent to the discharge opening (), a sealing surface () against which a valve stopper () which is located on the internal body () and closes the outlet channel () is spring prestressed.
