  • Publication number: 20140231540
    Abstract: Dispenser with a liquid storage unit, a dispensing head with a perforated plate component which has at least 25 dispensing openings in a dispensing opening region, with a pre-chamber connected upstream of the dispensing openings of the perforated plate component and from which the dispensing openings are supplied, and a connecting channel which connects the liquid storage unit to the pre-chamber. The perforated plate component is fastened on the dispensing head in an edge region and the dispensing opening region is pressed into a curved form by means of a curvature body which is arranged in the pre-chamber and acts with force upon the perforated plate.

  • Patent number: 8770448
    Abstract: Drop dispenser for releasing a pharmaceutical liquid in drop form, with a housing, a liquid storage and a discharge opening, which penetrates a wall of the housing and to which an outlet valve is assigned, for extracting the liquid. The discharge opening is surrounded by a drop-formation area on the outside of the housing, wherein this drop-formation area, at least in an outer region with respect to an alignment of the drop dispenser with the discharge opening pointing vertically downwards, has a shape tapering downwards and towards the discharge opening. The drop dispenser allows the release of drops with a constant size and shortens drying time.

  • Publication number: 20140048569
    Abstract: A liquid dispenser for dispensing drops including a housing, a liquid reservoir, a discharge opening through which liquid can be discharged from the liquid reservoir, and a drop formation surface surrounding the discharge opening, at which surface the liquid accumulates in order to be discharged from the drop formation surface as a drop. The drop formation surface has an outer limiting contour, the shape of which deviates from a circular shape. The dispenser is used to prevent contamination of the liquid to be dispensed.

  • Publication number: 20140042188
    Abstract: A dispenser for discharging liquids with a liquid reservoir for accommodating the liquid prior to being discharged, and a liquid outlet passage which leads to a liquid outlet opening through which the liquid reservoir communicates with to a surrounding atmosphere. In a use position, the liquid outlet opening is arranged below the liquid reservoir such that the liquid flows on account of the weight thereof in the direction of the liquid outlet opening, and the liquid outlet passage in the use position does not simultaneously permit air to enter the liquid reservoir and liquid to exit into the surrounding atmosphere. In order to reduce the internal volume of the dispenser and therefore to effect a discharge of liquid, a slide is pushed manually in an actuating direction from a stroke starting position into a stroke end position.

  • Publication number: 20130333492
    Abstract: A test device for a liquid dispenser including a base for stationary placement of the test device, a receiving device for receiving a liquid dispenser, and an actuation device configured for mechanical actuation of the liquid dispenser received in the receiving device. The test device is configured as a test device for a drop dispenser, wherein the receiving device and the actuation device are configured and arranged such that the drop dispenser can be received and actuated in a position where a discharge opening of the drop dispenser faces downwards.

  • Patent number: 8561859
    Abstract: A dispensing device for dispensing liquid media having a housing, an outlet opening for the medium, a medium reservoir for storage of the medium and a conveying device for transporting the medium from the medium reservoir to the outlet opening, wherein a flow brake is provided in a medium duct between the conveying device and the outlet opening. The flow brake has a first flow brake component which can be arranged and fixed relative to the housing or to a second flow brake component during assembly in several differing relative positions, wherein differing flow resistances of the flow brake are achieved depending on the selected relative positions.
