    • An aerosol delivery system (10) dispenses an active substance using a propellant fluid. The delivery system comprises a sealed pressurizeable container (12) having a dispensing nozzle (20). The propellant fluid is retained within the container (12) and releasable therefrom in a gaseous phase via the dispensing nozzle (20) when a release valve (22) is actuated. The dispensing nozzle (20) has a throat portion (40) creating a venturi effect when the gaseous phase of the propellant fluid passes therethrough. A fluid containing reservoir (24) is disposed within the container (12) in fluid flow communication with the dispensing nozzle (20). The active substance is contained within the reservoir (24) in isolation from the propellant fluid within the container. The venturi effect entrains the active substance through the dispensing nozzle (20) for ejection therefrom when the release valve (22) is actuated. A second reservoir (30) may also be disposed within the container (12) and provides a source of the gaseous propellant.
    • 气雾剂输送系统(10)使用推进剂流体分配活性物质。 输送系统包括具有分配喷嘴(20)的密封的可加压容器(12)。 当释放阀(22)被致动时,推进剂流体被保持在容器(12)内并且可以通过分配喷嘴(20)以气相从其释放。 分配喷嘴(20)具有喉管部分(40),当推进剂流体的气相通过其中时,该喉管部分产生文丘里效应。 容纳流体的容器(24)设置在容器(12)内与分配喷嘴(20)流体流动连通。 活性物质被容纳在储存器(24)内与容器内的推进剂流体隔离。 当释放阀(22)被致动时,文丘里效应通过分配喷嘴(20)夹带活性物质以从其喷射。 第二容器(30)也可以设置在容器(12)内并提供气体推进剂的来源。

    • The invention relates to an actuator (1) for a dispenser device for spraying contents of a receptacle that is pressurized or of a receptacle that has a pump. The actuator (1) comprises a channel connectable to a receptacle outlet (19) on one side of the actuator (1) for receiving the pressurized contents of the receptacle. The channel ends in an orifice (11) for spraying the contents on another side of the actuator (1). The channel comprises an expandable volume chamber (71). The orifice (11) is the outlet of the volume chamber (71). The orifice (11) is biased in the closed position. Actuation means allow a flow of content from the receptacle into the channel and volume chamber (71). This results in a pressure build up in the volume chamber (71). Actuation also attenuates the bias of the valve closing the orifice (11). The pressure build up will result in a burst opening of the orifice (11) through coupling with the expandable volume chamber (71).
