  • Patent number: 8596266
    Abstract: A discharging device, particularly for a pharmaceutical liquid, is adapted to accommodate and actuate a pump-type dispenser in an accommodating region. In the delivered state, the accommodating region of the discharging device is sufficiently large to ensure that the pump-type dispenser can be accommodated by the accommodating region when the dispenser has not yet been actuated and does not yet communicate with the outlet passageway. The discharging device is particularly useful for pharmaceutical liquids prone to oxidation and thus in need of extensive protection from contact with air.

  • Patent number: 8348096
    Abstract: A discharge device for liquid media having housing sections movable relative to one another along a total stroke between a non-actuated rest position and an actuated end position and together forming a manual actuating device. A media reservoir stores the medium prior to discharge, and a conveying device includes a discharge opening and a dosage chamber. The actuating and conveying devices are operatively coupled such that during a first partial stroke of the discharge actuation starting from the rest position the media reservoir and the dosage chamber are in communicating connection and during a second partial stroke of the discharge actuation following the first partial stroke the media reservoir and the dosage chamber are separated, the volume of the dosage chamber and the media reservoir being reduced by the second partial stroke of the discharge actuation.

  • Patent number: 8056765
    Abstract: A discharge device for media includes an outer housing with a discharge opening, a discharge handle for manual actuation. A support is arranged in the outer housing. Movable along a main axis relative to the outer housing and connected to the discharge handle, it has a seat for a pump dispenser. A pump is actuated by compression of the pump dispenser. A first abutment on the housing interacts with the pump dispenser, actuating the pump. The support has a functional portion which acts on the pump dispenser with a force oriented in the direction of the first abutment on the housing. An adjuster is provided between the handle and the functional portion of the support, by which the position of the functional portion relative to the first abutment on the housing can be adjusted for a defined setting of the discharge handle.
