Definitions

  • the invention relates to a discharge device for a fluid medium according to the preamble of claim 1.
  • a fluid dispenser which is particularly suitable for spraying germ-free liquids, e.g. Eye drops, is used.
  • the sealingly seated on a fluid container pump part and attached to the pump part actuator are protected against unintentional removal.
  • a comfortable and safe handling of the fluid dispenser is ensured at the same time.
  • a shell part is slidably disposed around at least the actuation path of a metering pump, so that actuation of the metering pump is possible.
  • a pump sprayer with an attached cap is known.
  • a lever arrangement is provided, which consists of two mutually pivotable in a plane operating levers and connected to this connector.
  • a connecting piece is articulated.
  • the connector has an approximately V-shaped configuration, the center piece of which forms a projecting point whose deflection causes the pumping movement of the spray head to spray the liquid in the pump atomizer downwards.
  • DE 602 17 545 T2 discloses an atomizing device with an actuating device. known system formed on the dispensing head, wherein the displacement or adjustment of the actuator differs from the sputtering device of the product through the discharge opening.
  • a discharge device for media in which the operating direction of the actuating element of the discharge device deviates from the stroke direction of the pumping element of the discharge device.
  • a coaxial arrangement of pumping element and media container is required.
  • the arrangement of the pumping element and its main extension axis and the actuating direction of the actuating element is predetermined, which lies in the axis of the pumping element or in the main axis of the container.
  • Such an actuation of the actuating element is not always the most ergonomically favorable arrangement of the actuating element.
  • the media container is therefore kept guided in a housing, in contrast, the media container is relatively movable.
  • a discharge stroke via this relative movement can be generated, for example, via an actuating element which acts on the media container via a deflecting means which differs from it.
  • This deflection means may be a pivotable lever which generates a force acting on the media container.
  • a disadvantage in turn, the requirement of a casing in the form of a housing, which leads the media container quasi sled-like, so that not the direction of the introduction of force is the cause of the actuation direction, but the guide in the housing.
  • the use of power deflection means arranged on the housing is thereby possible.
  • Disadvantageous again is the complex design and the requirement of a sheathing of the media container, which almost precludes a sensitivity for actuating the dispensing device. The user is virtually surprised by the spray since the movement of the discharge stroke is not visible. Since dosing accuracy is very important in pharmaceutical applications and is subject to stringent requirements, this is to be regarded as a clear disadvantage.
  • the object of the invention is therefore to provide a discharge device for a fluid medium, which is easy and reliable operable and easy to handle.
  • a discharge device in which the stroke direction of the pump part for conveying medium from the reservoir to the discharge opening and the actuating direction of the actuating device are different from each other.
  • a spiral spring whose sliding points are displaced in the form of gripping jaws on a workpiece, an application-related free movement of the jaws generated a compressive force in the stroke direction.
  • the force-displacement characteristic of an arcuate or bending spring which is compressible on its legs by a finger pressure, provides pressure forces that move the pump part and the reservoir to each other.
  • a lifting operation for dispensing medium is thereby generated.
  • About the terminals of the spiral spring in the pressure principle by a finger or handle is an elastic lifting movement, which also preferably only briefly comes into operation as long as the finger or handle exerts pressure. The ergonomics of the discharge is significantly improved.
  • the jaws are for increasing the resistance to deformation, i. for a higher stiffness, stiffened. Suitable for this purpose, for example, material reinforcements, stiffening ribs, etc ..
  • the spiral spring is preferably made of a plastic, in particular polypropylene (PP) or polyoxymethylene (POM).

  • FIGS. 2 to 5 schematically show parts of the discharge device according to FIG. 1 in an assembly sequence and after removal of a perforated freshness seal
  • FIG. 6a and 6b schematically show a side view and a section of the discharge device according to FIG. 1 in a rest position
