Definitions

  • the invention relates to a dispenser with which e.g. flowable Media released or discharged under pressure can. It is especially liquid media, but also pasty, powdery and / or gaseous media suitable.
  • the dispenser should be portable with one hand and simultaneously be operable for the discharge. He or most its parts should consist of injection molding or plastic.
  • the medium can be finely atomized, however, the donor is intended in particular to dispense individuals Media clusters or drops should be suitable. You have at least 5 or 15 and maximum 40 or 25 ⁇ l volume and contain medicinal agents for the treatment of the eyes or the like
  • the donor should be microbiologically as dense as possible contamination of the stored medium from the outside avoid.
  • the medium should be primed before first use. of the donor during the longest possible storage period, however even after the first media release against such impairments be protected.
  • the donor can be for a single Discharge of a media dose or be trained that the discharge operation until it is completely emptied is only moved in one direction. There is no return or Intake stroke required.
  • the entire media stock can be without additional media storage right from the start in a delivery chamber be included to promote the pressure of the medium is variable in volume.
  • the donor or the discharge can also work reversibly, namely repeatedly over one working stroke to promote pressure and one immediately Subsequent return stroke to suck in another media dose into the delivery chamber. After discharge of the media dose the microbiological seal should last until the next discharge always be restored, what with a disposable donor is not always required.
  • sealing is a single valve or are suitable for several valves. Their closing gaps are in Direction of flow in succession in the outlet channel. That downstream last valve is as close as possible to the media outlet or at the opening limitation of this outlet, the through the transition between an inner circumference and one this transverse end surface is formed. At this The transition separates the medium from all inner circumferences or Inner surfaces of the dispenser face outside, but can be downstream of which still directed to the outside surfaces of the dispenser become.
