操作部材56は、上記周壁６の外面に嵌着させた操作筒部58を有し、周壁６下方の操作筒部分から内向きフランジ58aを介して主筒部60を垂下している。この主筒部60の内周面には、縦方向の複数の第２係合溝62を縦設する。これら第２係合溝62は、周方向に等間隔に配置することが望ましい。また各第２係合溝62は、後述の第１係合溝74とほぼ同巾とする。これら両係合溝の内部に亘って一つの球状のボールを嵌合させるからである。図示例では図６に示すように２つのボールを両係合溝に係合させている。 The operation member 56 has an operation tube portion 58 fitted to the outer surface of the peripheral wall 6 and hangs the main tube portion 60 from the operation tube portion below the peripheral wall 6 via an inward flange 58a. A plurality of vertical second engaging grooves 62 are provided vertically on the inner peripheral surface of the main cylinder portion 60. These second engagement grooves 62 are desirably arranged at equal intervals in the circumferential direction. Each second engagement groove 62 has substantially the same width as a first engagement groove 74 described later. This is because one spherical ball is fitted inside both the engaging grooves. In the illustrated example, two balls are engaged with both engaging grooves as shown in FIG.
また図示例では、上記主筒部60の外周面の上部からは鍔状の第１取付リブ64Ａを突出し、その外周面の下部には第２取付リブ64Bを周設する。 In the illustrated example, a hook-shaped first mounting rib 64A protrudes from the upper portion of the outer peripheral surface of the main cylinder portion 60, and a second mounting rib 64B is provided around the lower portion of the outer peripheral surface.
さらに図示例では、主筒部60から第２案内筒部66を起立するとともに、この第２案内筒部66の上端から一定巾のフランジ状壁66ａを内方突出する。このフランジ状壁66ａの環状内端面は、後述の従筒部72が図４の状態からさらに上昇するときに、第２連結筒部70ａの外面に当接又は近接するように形成されており、従筒部72の昇降を間接的に案内する。 Further, in the illustrated example, the second guide tube portion 66 is erected from the main tube portion 60, and a flange-shaped wall 66 a having a certain width protrudes inward from the upper end of the second guide tube portion 66. The annular inner end surface of the flange-like wall 66a is formed so as to contact or be close to the outer surface of the second connecting cylindrical portion 70a when a later-described secondary cylindrical portion 72 further rises from the state of FIG. The raising and lowering of the sub-cylinder part 72 is indirectly guided.
昇降部材68は、水平円板状の連結基盤70の上面から上方へ第２連結筒部70ａを、連結基盤70の下面内周部から下方へスプリング装着用の短筒70bをそれぞれ突出している。上記第２連結筒部70ａは、可動底壁18の第１連結筒部22に連結している。さらに連結基盤70の下面外周部からは従筒部72を垂下している。この従筒部72は主筒部60に昇降自在に嵌合されている。従筒部72の外面には、第１係合溝74を形成する。この溝の構造・機能については後述する。 The elevating member 68 protrudes from the upper surface of the horizontal disk-shaped connection base 70 upward from the second connection cylinder part 70a, and from the inner periphery of the lower surface of the connection base 70 downwardly protrudes the short cylinder 70b for spring mounting. The second connecting cylinder part 70 a is connected to the first connecting cylinder part 22 of the movable bottom wall 18. Further, a slave tube portion 72 is suspended from the outer periphery of the lower surface of the connection base 70. The slave cylinder 72 is fitted to the main cylinder 60 so as to be movable up and down. A first engagement groove 74 is formed on the outer surface of the sub cylinder portion 72. The structure and function of this groove will be described later.

そして本実施形態においては、主筒部60の第２係合溝62と従筒部72の第１係合溝74とにより、主筒部60の回転力の一部で従筒部72を昇降させる変換手段Ｃを構築する。この作用を図６に基づいて説明する。同図は、従筒部72の外周面を平面形に展開して描いたものである。同図に示すように、第１係合溝74は、複数（図示例では２つ）の縦溝部74ａと、一方の縦溝部74ａの上端から他方の縦溝部74ａの下端へ至る同数の傾斜溝部74bとを有する。そしてこの第１係合溝74及び第２係合溝62に一つの剛性のボール75を嵌合すればよい。そうすると、ボールが傾斜溝部74bに位置している状態で、一点鎖線で示す主筒部60に白矢印の回転力が作用すると、従筒部72には黒矢印の方向の下降力が作用する。 In this embodiment, the secondary cylinder 72 is moved up and down by a part of the rotational force of the primary cylinder 60 by the second engagement groove 62 of the primary cylinder 60 and the first engagement groove 74 of the secondary cylinder 72. The conversion means C to be constructed is constructed. This operation will be described with reference to FIG. The drawing shows the outer peripheral surface of the sub-cylinder portion 72 developed in a flat shape. As shown in the figure, the first engaging groove 74 includes a plurality of (two in the illustrated example) vertical groove portions 74a and the same number of inclined groove portions extending from the upper end of one vertical groove portion 74a to the lower end of the other vertical groove portion 74a. 74b. Then, a single rigid ball 75 may be fitted into the first engagement groove 74 and the second engagement groove 62. Then, when the rotational force indicated by the white arrow acts on the main cylinder portion 60 indicated by the alternate long and short dash line while the ball is positioned in the inclined groove portion 74b, the descending force in the direction indicated by the black arrow acts on the slave cylinder portion 72.
図示例では、縦溝部74ａは垂直方向に延びているが、おおよそ縦方向に延びていれば足りる。また図示の傾斜溝部74bは展開図において直線的に描いているが、例えば特許文献１に開示されているように曲線的な形状でも構わない。 In the illustrated example, the vertical groove 74a extends in the vertical direction, but it is sufficient if it extends in the vertical direction. In addition, although the illustrated inclined groove portion 74b is drawn linearly in the developed view, it may have a curved shape as disclosed in Patent Document 1, for example.
オーバーキャップ94は、周壁６の上部に嵌着させている。好適な一実施例として、このオーバーキャップの適所に薬剤容器Ｂを組み付けることができる。組み付けの方法としては、オーバーキャップの一部に嵌合部を設けてもよく、また接着テープなどでオーバーキャップに留めるようにしてもよい。 The overcap 94 is fitted on the upper part of the peripheral wall 6. As a preferred embodiment, the drug container B can be assembled at a proper position of the overcap. As an assembling method, a fitting part may be provided in a part of the overcap, or it may be fastened to the overcap with an adhesive tape or the like.
上記構成によれば、図１の状態からオーバーキャップ94を外しかつ蓋50を開いて（図２参照）、液体容器Ｂが有するフランジ部Ｂ１を係止リブ46に載置するようにして、当該容器を薬剤収納室Ｒ内に収納する。そして蓋50を閉じると、薬剤容器Ｂは、第１押圧突子54と第２押圧突子40との間に挿まれて、シールフィルムＢ２が破断する。これにより容器内部の薬剤が外部に露出する。 According to the above arrangement, (see FIG. 2) state Remove the overcap 94 and open the lid 50 in FIG. 1, the flange portion B 1 having the liquid container B so as to place the engaging rib 46, The container is stored in the medicine storage chamber R. When the closing lid 50, the drug container B comprises a first pressing projections 54 typeset between the second pressing projections 40, the seal film B 2 is broken. Thereby, the chemical | medical agent inside a container is exposed outside.
次に把持筒部80を持ってスプレー装置を支えるとともに、操作筒部58を回転させると、ボール75は、第１係合溝74の一つの縦溝部74ａの下端位置（図２参照）から傾斜溝部74bを経て他の縦溝部74ａの上端位置（図３参照）に向かって移動するので、従筒部72は第２スプリング92の弾性力に抗して引き下げられる。従筒部72に追従して可動底壁18も下降するので、空気加圧室Ａ内が負圧化して、図３に示すように吸排気弁Ｖが開き、外気が噴霧ノズル42から空気加圧室Ａ内へ吸引される。 Next, while holding the gripping cylinder part 80 to support the spray device and rotating the operation cylinder part 58, the ball 75 is inclined from the lower end position of one vertical groove part 74a of the first engagement groove 74 (see FIG. 2). Since it moves toward the upper end position (see FIG. 3) of the other vertical groove portion 74a through the groove portion 74b, the sub cylinder portion 72 is pulled down against the elastic force of the second spring 92. Since the movable bottom wall 18 also descends following the sub cylinder portion 72, the pressure inside the air pressurizing chamber A becomes negative, the intake / exhaust valve V is opened as shown in FIG. It is sucked into the pressure chamber A.
次に図３の状態からボール75が他の縦溝部74ａ内に入ると、上記引下げ力が解放されるので、空気加圧室Ａ内の負圧が解消して、吸排気弁Ｖが閉じる。これとともに従筒部72及び可動底壁18が第２スプリング92の弾性力により上昇を開始し、第２スプリング92の弾性力と空気加圧室Ａ内の圧力とが釣り合う状態で停止する（図４参照）。 Next, when the ball 75 enters the other vertical groove 74a from the state of FIG. 3, the pulling force is released, so the negative pressure in the air pressurizing chamber A is eliminated and the intake / exhaust valve V is closed. At the same time, the secondary cylinder 72 and the movable bottom wall 18 start to rise due to the elastic force of the second spring 92, and stop in a state where the elastic force of the second spring 92 and the pressure in the air pressurizing chamber A are balanced (FIG. 4).
そして図５に矢示するようにノズルヘッド24を押し下げると、押下げ棒36で弁板16cが強制的に押し下げられるので、吸排気弁Ｖが開き、空気加圧室Ａ内の加圧空気が通気孔38を介して勢い良く薬剤収納室Ｒ内へ噴き込む。この噴流により気化した一定量の薬剤成分が噴霧ノズル42を介して外部へ噴出される。 When the nozzle head 24 is pushed down as shown by an arrow in FIG. 5, the valve plate 16c is forcibly pushed down by the push-down rod 36, so that the intake / exhaust valve V is opened and the pressurized air in the air pressurizing chamber A is The medicine is vigorously injected into the medicine storage chamber R through the vent hole 38. A certain amount of the chemical component vaporized by this jet is ejected to the outside through the spray nozzle 42.
図７は、本発明の第２の実施形態に係るスプレー装置の要部を示している。本実施形態では、蓋50は、弾性圧縮可能な帽子状の頂部51を有しており、この頂部51の裏面から第１押圧突子54を垂下している。この構成では、蓋50を閉じた状態でも第１押圧突子54の下端と第２押圧突子40との間には間隔が存する。この間隔が薬剤容器と同じ程度であれば、蓋50を閉めただけでは薬剤容器が破断することはない。蓋50の頂部51を押し下げたときに、薬剤容器Ｂを破断させることができる。 FIG. 7 shows a main part of a spray device according to the second embodiment of the present invention. In the present embodiment, the lid 50 has a cap-like top 51 that can be elastically compressed, and the first pressing protrusion 54 is suspended from the back surface of the top 51. In this configuration, there is a gap between the lower end of the first pressing protrusion 54 and the second pressing protrusion 40 even when the lid 50 is closed. If this interval is about the same as that of the medicine container, the medicine container is not broken only by closing the lid 50. When the top 51 of the lid 50 is pushed down, the medicine container B can be broken.
実施例では、別添の薬剤容器を薬剤収納室にセットし破断して使用していたが、最初から不織布などに含浸させた薬剤を薬剤収納室に収容して使用することも可能である。 In the embodiment, the attached medicine container is set in the medicine storage chamber and broken and used. However, the medicine impregnated in the nonwoven fabric or the like from the beginning can be accommodated in the medicine storage room and used.
