  • Patent number: 4324242
    Abstract: A two-step release valve unit for a feminine syringe wherein a valve member and nozzle serve to open and close a dispensing port for an expandable syringe bag. The valve unit includes a slidable nozzle member which in one position will open a valve element. A two-step frictional engagement is provided between the nozzle member and the valve member housing so that the nozzle is retentively held out of contact with the valve element in a first position yet can be released therefrom to engage and open the valve element in the second position. When the nozzle member is removed, the bag is easily filled through a filling orifice in the valve member.
