The invention relates to a spray device adapted to provide multiple, unit doses of a fluid, each dose having a volume in the range from about 1 to about 100 mu lambda , the device comprising an elastomeric, self-sealing valve having a fluid side and a delivery side, the valve opening to allow passage of the fluid when pressure is applied to fluid on the fluid side and sealing when the pressure is removed. The valve achieves a clean stop-start flow of the fluid at low fluid volumes. The device is particulary suitable for low volume medical applications such as nasal spraying. |
