A discharging device for discharging liquids includes an outer housing encompassing an inner chamber, a liquid storage receptacle, a discharge orifice, a delivery device for delivering liquid from the storage receptacle to the discharge orifice, a cap that covers the discharge orifice when present on the outer housing in a safety position, and a manual actuator adapted to actuate the delivery device and which is movable relative to the outer housing between a neutral relative position and an actuated relative position. The cap and the manual actuator cooperate so that displacement of the manual actuator is mechanically blocked when the cap is in its safety position. A locking element that is movable in relation to the outer housing is constrainedly coupled with the movement of the manual actuator and extends in the actuated position through a hole in the outer housing to a region that the cap blocks when mounted in its safety position.

Discharging device

A discharging device for discharging liquids includes an outer housing encompassing an inner chamber, a liquid storage receptacle, a discharge orifice, a delivery device for delivering liquid from the storage receptacle to the discharge orifice, a cap that covers the discharge port orifice when present on the outer housing in a safety position, and a manual actuator adapted to actuate the delivery device and which is movable relative to the outer housing between a neutral relative position and an actuated relative position. The cap and the manual actuator cooperate so that displacement of the manual actuator is mechanically blocked when the cap is in its safety position. A locking element that is movable in relation to the outer housing is constrainedly coupled with the movement of the manual actuator and extends in the actuated position through a hole in the outer housing to a region that the cap blocks when mounted in its safety position.

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.

A first reservoir body ( ) includes two necks ( ). One neck ( ) carries a thrust piston pump ( ) including a medium outlet ( ). The other neck ( ) carries a closed second reservoir body ( ) including a second medium. When the closure ( ) is opened, the second medium is transferred into the first reservoir body ( ) where it is mixed with or dissolved in the first medium. Thereafter, the mixed media can be discharged by the dosing pump ( ) from the first reservoir body ( ) in discrete doses in sequence. Thus, the media are stored separately and are not merged until being discharged.

Media dispenser

A locking ring ( ) is provided for assisting axial insertion and snap fit of an actuating head ( ), including a pump ( ), to a medium reservoir base ( ) while protecting the pump ( ) against actuation or excessive forces encountered during assembly. The locking ring ( ) can be disengaged to allow actuation of the pump ( ) and then re-engaged to permit actuation.
