ABSTRACT:
This douche nozzle provides a linear valve which is constructed in the stem of the nozzle. This valve is closed to fluid flow when in the outer position and is open in the inner condition. The valve is made with telescoping tubular portions and a stop means is provided so that the linear valve is not accidently moved from its fluid flow stop condition and position. This nozzle is used with a collapsed flexible bag whose open end is fed through a tubular collar and the end of this bag is reversed with a short end portion brought along the outer surface of the collar. The nozzle has an enlarged end and a skirt portion which mates with and mounts on the outer portion of the collar so as to retain this bag with the nozzle.
