A dispensing apparatus for a liquid product, the apparatus comprising a) a housing () or frame (), b) a receptacle () for the liquid with a feed nozzle () arranged substantially stationary with respect to the housing or frame, c) a dosing chamber () having an orifice (), d) a mechanism arranged to allow at least ejection of liquid through the orifice and e) a through passage () arranged to allow the ejected liquid to pass in a direction different from the feed nozzle or opening. The mechanism comprises a mobile element arranged movable with respect to the housing or frame between at least a first position in which the orifice of the dosing chamber and the feed nozzle or opening are in flow communication and a second position in which the orifice and the through passage are in flow communication and the mechanism is arranged to allow aspiration of liquid through the orifice when the mobile element is in the first position and ejection of liquid through the orifice when the mobile element is in the second position. A method for operating the device comprises the steps of i) connecting the orifice and the nozzle or opening in flow communication, ii) filling liquid into the dosing chamber through the orifice, iii) aligning the orifice with the through passage, and iv) ejecting liquid from the dosing chamber through the orifice.

Dispensing apparatus and method for liquid products, particularly medicinal products

A device and use method for ejecting a liquid stream towards an eye, the stream moving from a proximal position towards a distal position, the device comprising a) a housing, b) a container for the liquid, c) at least one opening arranged for ejection of the stream and being in fluid communication with the container, d) a pump mechanism operable to deliver at least part of the liquid from the container through the opening to form the stream and e) an eyecup with a contact surface arranged for contact with the eye or its facial surroundings. The eyecup is arranged movable with respect to the opening or housing between at least two positions i) an active position with said eyecup contact surface at a defined safety distance to the opening and ii) a rest position with the eyecup contact surface at a position more proximal than in the active position and a sensor is arranged to allow discrimination between the positions. The pump mechanism may include a pump driver able to store cocked energy for driving the pump mechanism and at least one activation mechanism may be present and operable to initiate the device for the liquid delivery, whereby a driving mechanism is arranged to transform manual or stored energy both i) into cocked energy of the pump driver and ii) into direct or stored energy for operation of the activation mechanism.
