Abstract
The spray-dispenser device (10) dispenses a dose of liquid medicament contained in a cylindrical vial (18) by the action of a piston (26). The device comprises an operating rod (44) for the piston (26) and a channel (37, 50, 52) for connecting the interior of the vial (18) to a spray nozzle (54). The vial (18) is to be thrown away after dispensing. The vial (18) already contains the piston (26), which seals the vial. The piston (26) is automatically connected to the rod (44) on inserting the vial (18) into the body (11). In the piston there is provided a valve which interrupts the emission channel (37, 50, 52). The valve opens as a result of the operation of the piston (26).
