Patent ID: 7735689

Claim:
A fluid dispensing device connectable/disconnectable to/from a container suitable for containing a fluid, wherein the device comprises: pumping means suitable for being actuated for dispensing the fluid outside the device, wherein the pumping means comprises a) an enclosure delimiting a pumping chamber for containing the amount of fluid to be dispensed; b) a piston suitable to slide in the enclosure along a dispensing axis for forcing dispensing of the amount of fluid to be dispensed, the device being suitable for dispensing the fluid in the direction of the piston dispensing axis; c) a dispensing duct operatively connected to the pumping chamber for conducting an amount of fluid to be dispensed outwards; actuating means suitable for being handled for actuating the pumping means, comprising a trigger comprising an actuating portion for influencing the piston; manually actuable closing means cooperating with the dispensing duct for closing the duct and preventing the fluid from dispensing, comprising a nozzle; manually actuable locking means cooperating with the pumping means, suitable for limiting the piston travel in the enclosure for preventing the fluid from dispensing; wherein the nozzle, by means of its rotation, brings the closing means to an open configuration in which the fluid communication between the dispensing duct and the external environment is restored and brings the locking means in an unlocked configuration in which the pumping means are actuable for dispensing the fluid, and in that the piston engages with the nozzle in rotation, and wherein the locking means comprises at least one projection projecting from the piston; at least one slot located in the enclosure, wherein the slot comprises a sliding portion, parallel to the dispensing axis, and a locking portion, having an inclined axis relative to the dispensing axis; and wherein the piston is turnable in the enclosure about the dispensing axis for allowing the introduction of the projection in the locking portion of the slot and limiting the piston travel.
