本発明ではノズルB₄の押し下げ回数を認知し、牽いては噴出液の噴出回数即ち噴出量を認知する認知システムを備えており、該認知システムは回転部材B₅を押釦B₉の押し下げにより所定角度回動させる回転機構と、該回転機構と連繋させるとともに、所定回数の押釦B₉の押し下げ時にステム４の押し下げを防止するロック機構とから構成している。 The present invention recognizes the number depression of the nozzle B _4, drawn is provided with a cognitive system to recognize the jetting number i.e. ejection amount of the ejection liquid, predetermined by the recognition system depressing a rotating member B ₅ of the push-button B ₉ a rotating mechanism for angular rotation, with is cooperative with said rotating mechanism constitute a lock mechanism for preventing the depression of the stem 4 when depressed a predetermined number of push button B _9.

回転機構は、前記仕切板30と、前記回転部材と、前記リング部材B₈とを備え、前記押釦の押し下げ時に第２傾斜面s₂が当接する第３傾斜面s₃及び隣接する第１傾斜面s₁上を摺動して回動腕53が隣接する仕切板30t を乗り越える如く構成している。図４を用いて説明すれば、図４(a) は回動腕53が幅広部32の隣の仕切板間に位置した状態であり、この状態から、押釦B₉を押し下げることによりリング部材B₈及び回転部材B₅を第１コイルスプリングB₆，第２コイルスプリングB₇及びステム４の上方付勢力に抗して押し下げると、第２コイルスプリングB₇がフランジ40を押し下げることによりノズルB₄を押し下げ、所定量の液を噴出する。また、回動腕53は当初隣接する仕切板30t に案内されて下降し、図４(b) の位置に達すると仕切板30から回動腕53が外れるため上方付勢力により第２傾斜面s₂が残りの第３傾斜面s₃を摺動して図４(c) の位置まで回動腕が回動し、次いで押釦B₉の押圧を解除すると第２傾斜面s₂は第１傾斜面s₁上を摺動し（図４(d))、回動腕53は当該仕切板30を乗り越えて次の第３傾斜面s₃上に回動する。この際被係止面ｂが係止面ａ上方に位置している（図４(e))。 Rotating mechanism, and the partition plate 30, and the rotating member, the ring member B ₈ and comprises a second inclined surface s ₂ abuts third inclined surface s ₃ and the adjacent first inclined upon depression of the push button slide on surface s ₁ swing arm 53 is composed as overcome adjacent partition plates 30t. If described with reference to FIG. 4, FIG. 4 (a) is a state where the rotational arm 53 is located next to the partition plates of the wide portion 32, in this state, the ring member B by depressing the push button B _{9 When the 8} and the rotating member B ₅ are pushed down against the upward biasing force of the first coil spring B ₆ , the second coil spring B ₇ and the stem 4, the second coil spring B ₇ pushes down the flange 40, thereby causing the nozzle B _4. Is pushed down and a predetermined amount of liquid is ejected. The rotating arm 53 is initially guided by the adjacent partition plate 30t and descends. When the rotating arm 53 reaches the position shown in FIG. 4 (b), the rotating arm 53 is detached from the partition plate 30. ₂ slides on the remaining third inclined surface s ₃ , the rotating arm rotates to the position of FIG. 4 (c), and then the push button B ₉ is released, the second inclined surface s ₂ becomes the first inclined surface. It slides on the surface s ₁ (FIG. 4D), and the rotating arm 53 gets over the partition plate 30 and rotates on the next third inclined surface s ₃ . At this time, the locked surface b is positioned above the locking surface a (FIG. 4 (e)).

ロック機構は、取付部材B₁内所定位置に係止面ａを設けるとともに、回転部材B₅の所定位置に係止面ａに当接する被係止面ｂを設けて回動腕53の下降を防止する。図示例では、取付部材B₁内所定位置に突設した棒状の突部15の上面を係止面ａとし、回転部材B₅の下部筒壁部52外面で且つフランジ部51下面の所定位置に設けた凸部57下面を被係止面ｂとしている。そして、回動腕53が回動して所定位置まで回動移動した際には押釦B₉を押し込んでも被係止面ｂが係止面ａに当接して下がらず、その結果、ステム４の下降を防止して液の噴出がなく、所定噴出量の液を噴出したことを触覚的に認知できる。尚、係止面ａと被係止面ｂとの間には、図示例の如く、液の噴出が生じない程度にステムの僅かな押し下げが生じる如く、若干の隙間を設けても良い。隙間により作動がより円滑となる。 The locking mechanism is provided with a locking surface a at a predetermined position in the mounting member B ₁ and a locked surface b that abuts the locking surface a at a predetermined position of the rotating member B ₅ to lower the rotating arm 53. To prevent. In the illustrated example, the upper surface of the rod-shaped protrusion 15 projecting at a predetermined position in the mounting member B ₁ is used as a locking surface a, and the outer surface of the lower cylindrical wall portion 52 of the rotating member B ₅ is positioned at a predetermined position on the lower surface of the flange portion 51. The lower surface of the provided convex portion 57 is the locked surface b. Then, the locking surface b also pushes the push button B ₉ is when the swing arm 53 is pivoted moved to a predetermined position by rotating the not lowered in contact with the locking surface a, as a result, the stem 4 It is possible to tactilely recognize that a predetermined amount of liquid has been ejected without preventing the liquid from descending. It should be noted that a slight gap may be provided between the locking surface a and the locked surface b so that the stem is slightly pushed down to the extent that no liquid is ejected as shown in the example of the drawing. The operation becomes smoother due to the gap.

また、本例ではロック機構によるロック状態を解除するロック解除機構を設けている。このロック解除機構は、ロック機構により一旦所定の噴出量の噴出が終了した後、新たに始めから所定噴出量の噴出が行える如く構成したもので、前記回動腕53が幅広部32位置に回動した際に係止面ａ上方に被係止面ｂが位置し、また、押釦B₉を回転部材B₅に対して回転させた際に、押釦B₉が所定回転位置で回転部材B₅と係合する如く構成し、押釦B₉を回転させることにより回転部材B₅を回転させ、係止面ａ上方の被係止面ｂを移動させる如く構成している。 In this example, a lock release mechanism for releasing the lock state by the lock mechanism is provided. This unlocking mechanism is configured such that after the ejection of a predetermined ejection amount is once completed by the locking mechanism, a predetermined ejection amount can be newly ejected from the beginning, and the rotating arm 53 is rotated to the position of the wide portion 32. located is locked face b to locking surface a upward upon motion, also the time of rotating the push button B ₉ with respect to the rotation member B _5, the rotating member B ₅ push button B ₉ is at a predetermined rotational position and it was composed as to engage to rotate the rotating member B ₅ by rotating the push button B _9, constitute as moving the locking surface b of the locking surface a upward.

For example the push button B ₉ push in pressure contact with the scalp or the like, ejecting a storage solution push the nozzle B _4. Be performed appropriately by changing the location indentation of similar push button B _9, the rotating member B ₅ is the in each case by a predetermined rotation angle rotation reaches a predetermined number of times the swing arm 53 is positioned locking surface a upward You can no longer push it down. At this time, a display 54 such as an end character can be seen from the display window hole 24, and the end can be recognized visually. Moreover, the next time if used, by further rotation after the projection 92 by rotating the push button B ₉ engaged with projection 56 of the rotating member B _5, on the engaging surface a round The moving arm 53 is displaced and the liquid can be ejected, and a predetermined amount of liquid can be ejected again.
