<P>PROBLEM TO BE SOLVED: To provide a jet button with a continuous flow valve in which a given quantity jetting function is added to a jet button to be mounted on a valve stem. <P>SOLUTION: A cylinder part 29 for constituting continuous flow valve chamber 23 is provided in jet button body 20 so as to surround a nozzle part 25. A valve sheet part 10, which is attached at its base to a valve stem 3 and has, at its front end, a valve sheet 17 for closing an annular valve body 27 provided at the proximal end of the nozzle part 25, is inserted into the cylinder part 29. The outer periphery face of the base 11 is guided vertically slidably in a sealed state on the inner periphery face of the cylinder part 29. When the jet button body 20 is depressed, a coil spring 15 is compressed to close a valve port 16. Next, the valve stem 3 is made to descend for opening. This allows the contents to pass through a communicating passage 14 and to be filled into a continuous flow valve chamber 23. Subsequently, when the depression of the jet button body 20 is released, the valve stem 3 is closed and, in addition, the valve port 16 is opened by elastic restoring force of the coil spring 15. Consequently, the contents filled into the continuous flow valve chamber 23 is jetted from the jet port. <P>COPYRIGHT: (C)2004,JPO |
