ABSTRACT:
A dispensing apparatus for a liquid product, the apparatus comprising a) a housing (2) or frame (3), b) a receptacle (4) for the liquid with a feed nozzle (4a) arranged substantially stationary with respect to the housing or frame, c) a dosing chamber (11) having an orifice (11a), d) a mechanism arranged to allow at least ejection of liquid through the orifice and e) a through passage (7) 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.
