PROBLEM TO BE SOLVED: To provide a new syringe type ejector stably frothily or mistily discharging a content liquid without impairing operability even if the amount of the content liquid is small while making the content liquid cartridged.SOLUTION: This syringe type ejector is formed with the cartridge by: forming a cartridge body 1A-1 forming a sealed space by sealing the inside of the tip of a cylindrical member 6 by a pressure release valve 7 and sealing the inside of the rear end by a plunger 8 and storing a nozzle incorporating a mesh ring as an auxiliary cartridge. The pressure release valve 7 has a valve element 7a which is held on the tip side of the cylindrical member 6 through an elastic member 7b and can move against the energizing force of the elastic member 7b by a pressure received from the content liquid, and the inside of the cylindrical member 6 is formed with inner grooves 6c forming passages of the content liquid between the valve elements 7a and the cylindrical member 6 by the movement of the valve element 7a.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、泡状又は霧状に安定して吐出できる、新規なシリンジ型噴出器を提供する。【解決手段】筒状部材6の先端内側を圧力解除弁7によって密封するとともに後端内側をプランジャ8によって密封して密封空間を形成するカートリッジ本体1A-1を形成するとともに、メッシュリングを内蔵したノズルを補助カートリッジとして収納することでカートリッジを形成し、圧力解除弁7は、筒状部材6の先端側で弾性部材7bを介して保持されるとともに内容液から受ける圧力によって弾性部材7bの付勢力に抗して移動可能な弁体7aを有し、筒状部材6の内側に、弁体7aの移動によって当該弁体7a7aとの間に内容液の通路を形成する内溝6cを設けた。【選択図】図7
