摘要

PURPOSE:To mix the mist ejected and the outside air and form foamer foam by piercing an outside air sucking hole to the nozzle hole forming wall between a side wall and a nozzle front end. CONSTITUTION:A spraying nozzle 7 is fitted with a foamer foaming cap 25 by the outside circumferential wall 26 screwed to the outside circumferential face of a cylindrical part 8. This cap 25 is provided with an inside circumferential wall hole 29 which opens the center of a front wall 27 and forms the front part of the nozzle hole 51 of the foamer foam discharger and is provided with a groove 30 for forming an outside air lead-in hole at the rear end face. It is also provided with an inside circumferential wall 28 and a through-hole 31 communicating with the groove 30 between the same and an outside circumferential wall 26. When the cap 25 is screwed to the nozzle 7, the front face of the top wall 9 of the spraying nozzle cap and the rear end face of the inside circumferential wall contact closely and the groove 30 forms an outside air suction hole 32. On the other hand the spray hole 10 of the side wall 52 is opened to the inside circumferential wall hole 29.
