摘要: A nozzle mechanism (27) for generating an aerosol-type liquid discharge is provided, which nozzle (2) ensures one-way movement of liquid during and also has a substantially zero "dead volume" at the tip of (2). The nozzle includes flexible nozzle portion (10) with an outlet (108) fluid channel (104), rigid shaft (102) received within the flexible portio (10), housing surrounding portion and exposing (108). The (102) interfaces to form first normally-closed, one-way valve (105), as well define a swirling chamber (103) collecting which has been channelled from reservoir, prior to being discharged via outlet. (108) has tubular wall thickness that decreases along the elongated axis symmetry (108) toward channel (104) circumferentially positioned create swirling action of delivered said chamber (103). Once pressure on liquid reaches threshold sufficient radially deform forming the first normally-closed in the swirling through the outlet coupled to a body (107) which a substantially shape which decreases bottom toward (10). rigid shaft nozzle portions extends down into body portion so second interfaces (107) to normally-closed, (106) in communication path between liquid reservoir (103).
