Definitions

  • the invention relates to a metering device for metered delivery of a fluid, in which a storage container is connected to a dosing, wherein in the dosing head, a spindle is guided, which has a passage for the fluid to be transported.
  • a fluid dispenser for a germ-free fluid described in which a reservoir is connected to an actuating button and for transporting the fluid a piston-cylinder system is provided.
  • a tightness of such a fluid delivery device is particularly important to realize a sterile system for sensitive fluids.
  • such fluid delivery devices with a piston-cylinder system have the disadvantage that the amount to be transported is not always exactly determinable.
  • problems in when eye-drops are to be used as a germ-free fluid are described in the EP 0 473 892 A2 are described difficulties in when eye-drops are to be used as a germ-free fluid. For this application, it is important that a so-called "oligodynamic effect" is exploited. The realization of such an oligodynamic effect is also not easy in piston-cylinder systems.
  • the EP 1 214 984 A2 is aimed at a donor for media.
  • the dispensing head of the dispenser has a support body and a relative to this by a resilient connection, namely a bendable channel portion, pivotable head body with the media outlet.
  • the bending of the channel portion is guided by a uniaxial joint and the pivotal movement an actuating handle for manual actuation of a discharge stroke of a pump is accessible.
  • the WO 2009/109370 A1 relates to a metering device for metered dispensing of liquid preparations, in particular for metering of medicinal, pharmaceutical and cosmetic liquid preparations, wherein the use of preservatives can be dispensed with.
  • the WO 2004/058413 A1 is directed to a liquid product dispenser intended to be mounted to the mouth of a liquid product container.
  • the US 6,422,434 B1 relates to a large dose dispenser pump having a downwardly directed nozzle tip and an outlet valve assembly in a nozzle.
  • the DE 197 42 890 A1 is directed to a dispenser for receiving and dispensing products of all kinds without the use of propellants.
  • the dispenser consists essentially of a bellows-shaped container for receiving the contents, one or more spring packs, a lock in the lower area and a cover in the upper area. This pressure unit is inserted into a sliding ribbed outer container.
  • the EP 0 492 354 A1 relates to a dosing and spray pump for dispensing liquid, low-viscosity and pasty substances.
  • an elastic bellows connecting between two telescopically movable plastic housing parts is arranged, which has a valve outlet at one end as a discharge valve, which surrounds the lateral surface of an integrally formed on the first housing part annular wall sealing and liftable.
  • the bellows at its other end a valve ring wall which sealingly and liftably abuts on the lateral surface of an integrally formed on the second housing part valve seat (42), through which the pumping medium is sucked into the bellows.
  • a metering device according to claim 1 is thus proposed, wherein in the operating state a reservoir is connected to a dosing head, wherein in the dosing head a spindle is guided, which has a passage channel which connects the outlet and the inlet valve.
  • the embodiment according to the invention also has the advantage that the exhaust valve can be designed in a variety of ways by the construction described above, so that u.a. e.g. also a ball valve can be used.
  • the use of a ball valve has the advantage that this e.g. can be formed as a silver-coated metal ball, so that thus an oligodynamic effect can be exercised.
  • Another advantage of the metering device according to the invention is that a safe, even from the volume accurate metering of the fluid to be administered can be realized.
  • the metering device according to the invention thus offers a high degree of sterility and operational safety through the novel spindle system.
  • the dosing device is constructed so that the spindle is guided in the dosing head and the pump housing, wherein the spindle is designed as a cylindrical member having a central bore, which then forms the passageway.
  • the advantage of such a construction is that it allows an optimal connection between the outlet and the inlet valve can be made.
  • the passageway is preferably constructed such that it is widened in the direction of the inlet valve. This ensures that in conjunction with the inlet valve, the fluid to be sucked can be optimally transported into the passage.
  • Another essential Element of the device according to the invention is that in the spindle of the passageway is then dimensioned in the direction of the exhaust valve so that the exhaust valve can engage in the passageway.
  • the passageway is thus dimensioned on the outlet side and formed so that it then cooperates with the outlet valve, which can be configured in many ways, in order to achieve optimum tightness.
  • the passageway should preferably have a small length, so that a small residual volume can be achieved.
  • a bellows or a foil bag may be arranged.
  • the bellows and the inner or foil bag strive back due to their own material thickness in their original position, creating a suction force that allows a further improved sealing.
  • the reservoir is preferably a cylindrical container and the opening is arranged in a tapered region, which is designed as a neck.
  • this embodiment of the reservoir is preferred.
  • the formation of the neck is favorable in such a way that then can be arranged on the outside of the neck for connecting the dosing with the pump housing a snap connection.
  • the snap connection connects the reservoir to the pump housing and the dosing head.
  • the dosing is preferably a spring or a bellows, preferably with integrated sealing function, between the inside arranged the metering head and the snap connection.
  • springs in this case preferably springs made of metal can be used.
  • the latching connection is connected via a first seal to the opening of the storage container.
  • This first seal is preferably arranged on the end face of the neck and can thus serve to seal the latching connection with the pump housing.
  • a further improvement can also be achieved if a second seal, between the snap-in connection and the spindle is provided in the interior of the pump housing. The spindle is then passed through this seal.
  • a great advantage of the metering device according to the invention is that a large variability with respect to the outlet valve is possible by means of the spindle system.
  • Plastic valve is used as inlet valve.
  • the outlet valve may be in the form of a ball valve.
  • the valve seat is then formed in the spindle itself.
  • the ball and spring which cooperate are located in the metering device at the appropriate location and then cooperate with the valve seat.
  • the exhaust valve is to provide a bellows or a valve piston instead of a ball.
  • bellows-like springs which together with a plastic cone form the outlet valve may be provided.
  • the outlet valve can also be formed by a specially designed cone, in which case the cone itself has an outlet opening. This cone then acts again as a valve known with a ball and a spring together.
  • the ball which is provided in the outlet valve, be coated with silver.
  • ceramic balls, steel balls, glass balls or silver-copper balls can be used.
  • metal springs or plastic-coated metal springs or plastic springs can be used.
  • a bellows or a plastic or foil bag for storing the fluid may be provided.
  • the bellows can, as in and of itself known from the prior art, also have a drag piston. It is also preferred in the metering device according to the invention when the bellows has at least one fold a contact device which is in contact with the inside of the reservoir. In this way it can be achieved that with the contact device an optimal sliding of the bellows is ensured via the contact device with the inside of the reservoir. This also makes it possible that the bellows or inner bag retains its original position.
  • the dosing head itself may be selected from the abovementioned materials, in which case an additive, specifically silver, is additionally incorporated. This additive is then pressed upon actuation, i. Upon passage of the fluid through the outlet opening come in contact with silver, so that an oligodynamic effect can be realized.

Due to the increased internal pressure closes the inlet valve 7, while the outlet valve 9 closes by the ball 17 is pressed against the spring 18 due to the internal pressure. This allows the solution to escape from the opening 16.
