PROBLEM TO BE SOLVED: To avoid direct exposure to the eyes when using a carbon dioxide gas supply cylinder, which forms a lotion mixed with carbon dioxide, to wipe off unnecessary awkward feeling and feeling of anxiety and further to effectively work a jetting gas pressure of the carbon dioxide gas supply cylinder for opening/closing of a nozzle part.SOLUTION: In a facial treatment apparatus, carbon dioxide gas guided through a flexible hose P from a carbon dioxide gas supply cylinder B is made to jet out from a jet nozzle at the tip end of a spray body, and then, together with a lotion in a cup, the lotion mixed with carbon dioxide is jetted while being atomized. On the upper side surface of an upper cylindrical body 1, an internal thread is formed in the inner side surface of a mounted circular adjusting knob. Further, on the upper side surface of the upper cylindrical body 1, a boss is stood which has a diameter smaller than the outer diameter of the upper cylindrical body 1. An external thread is formed on the outer periphery of the boss, and threadedly engaged with the internal thread of the circular adjusting knob, and thereby, the circular adjusting knob is rotated and vertically moved. Further, a non-threaded groove is formed between the upper side surface of the upper cylindrical body 1 and the external thread of the boss, and there is formed a fall-off prevention screw, which is screwed from the side face of the circular adjusting knob and in which the tip end is situated in the non-threaded groove.COPYRIGHT: (C)2014,JPO&INPIT【課題】炭酸混合化粧水を生成する炭酸ガス供給用ボンベが使用時において直接目に触れない様にし、不必要な違和感、不安感を払拭する。更には炭酸ガス供給用ボンベの噴出ガス圧をノズル部の開閉に有効に作用させる。【解決手段】炭酸ガス供給用ボンベBから可撓性ホースPを介して導かれた炭酸ガスをスプレー本体の先端噴出ノズルから噴出させてカップ内の化粧水と共に、炭酸混合化粧水を霧状に噴射する様にした美顔器に於いて、上側筒体1の上部面に、装着された円形調整用摘子の内側面に雌ネジを形成し、上側筒体1の上部面に、該上側筒体1の外径より小径のボスを直立させると共に、該ボスの外周に雄ネジを形成して円形調整用摘子の雌ネジに螺合して円形調整用摘子を回転上下させ、更に前記上側筒体1の上部面とボスの雄ネジとの間にネジ無し溝を形成し、円形調整用摘子の側面からねじ込んで先端がネジ無し溝に位置する抜止め用ネジとした。【選択図】図4
