PROBLEM TO BE SOLVED: To provide a new syringe type ejector capable of ejecting a liquid as a foam-like liquid or a mist-like liquid without impairing the operability even if the amount of the liquid is small while enabling the content liquid to be contained in a cartridge.SOLUTION: The ejector includes: an operation device 1B which allows a rod 3c disposed in a through-hole formed in a distal end cylindrical portion 2c of a syringe 2 to be formed extending in a piston 3a slidably disposed in the syringe 2, and forms a path r1 of air force-fed by the piston 3a between the rod 3c and the distal end cylindrical portion 2c a cylindrical member 6 which is filled with a content liquid C and has a plunger 7 for extruding the content liquid C by using pressing force from the rod 3c as urging force a nozzle 8 which houses the cylindrical member 6 in the inside and is attached to the distal end cylindrical portion 2c and a mesh ring 9 which is housed in the nozzle 8 and forms a foam-like content liquid from the content liquid C extruded from the cylindrical member 6 via the air force-fed by the piston 3a.COPYRIGHT: (C)2013,JPO&INPIT【課題】内容液のカートリッジ化を図りつつ、少量の内容液であっても操作性を損なうことなく、泡状又は霧状に注出できる、新規なシリンジ型噴出器を提供する。【解決手段】シリンジ2内に摺動可能に配置したピストン3aに、シリンジ2の先端筒部2cに形成した貫通孔に配置されるロッド3cを延在させるとともに、ロッド3cと先端筒部2cとの間にピストン3aで圧送した空気の通路r1を形成する操作器具1Bと、内容液Cを充填するとともに当該内容液Cをロッド3cからの押圧力を付勢力として押し出すプランジャ7を有する筒状部材6と、筒状部材6を内側に収納して先端筒部2cに装着されるノズル8と、ノズル8の内側に収納されて筒状部材6から押し出された内容液Cとピストン3aで圧送された空気を通して泡状の内容液とするメッシュリング9とを備える。【選択図】図1
