Actuator for a receptacle having a pressurized content and method for spaying a pressurized content

摘要

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).
