Description
本発明は、正倒立両用液体噴出器に関する。 The present invention relates to a right / left inverted liquid ejector.
正倒立両用ではないが、液体噴出器として、容器体内へ下半部を挿入したシリンダ内の外面に嵌合した補強筒部から容器体口頸部への係止用の外向きフランジを突出するとともに、上記シリンダ内を摺動する筒状ピストンから起立するステムの上部にノズル付きヘッドを形成し、また上記口頸部外面へ嵌合した装着筒部の上端部から内向きフランジを突出するとともに、内向きフランジの内周から、補強筒部及びステムの外面を覆うピストン抜止め用筒部を起立したものが知られている（特許文献１）。この液体噴出器は、液体の噴出に伴う内容液の減少に伴い、容器体内が負圧化することを防止するため、上記ステムとピストン抜止め用筒部との隙間から、シリンダの上部に開口した通気孔を経由して容器体内へ連通可能な空気流路を形成している。 Although it is not for both sides upside down, as a liquid ejector, an outward flange for locking to the container neck of the container body protrudes from the reinforcing cylinder part fitted to the outer surface of the cylinder with the lower half inserted into the container body In addition, a head with a nozzle is formed on an upper portion of a stem that rises from a cylindrical piston that slides in the cylinder, and an inward flange projects from an upper end portion of a mounting cylinder portion that is fitted to the outer surface of the mouth-neck portion. In addition, there is known a structure in which a piston retaining cylinder portion that covers the outer surface of the reinforcing cylinder portion and the stem is erected from the inner periphery of the inward flange (Patent Document 1). This liquid ejector is opened to the upper part of the cylinder from the gap between the stem and the piston retaining cylinder part in order to prevent negative pressure in the container body due to the decrease in the content liquid accompanying the liquid ejection. An air flow path that can communicate with the container body is formed through the vent hole.

Sometimes liquid can leak through the air flow path.

The front portion of the cylindrical wall portion is a small inner diameter portion that is reduced in diameter via the stepped portion 73, and the second valve seat v2s is formed in the small inner diameter portion.

Further, a through hole 77 is opened at the longitudinal intermediate portion of the cylinder 75, and a large diameter piston portion 78 having a tapered shape with a large front end is projected from a cylinder part behind the through hole 77. The large diameter piston portion 78 is in contact with the cap cylinder wall portion behind the stepped portion 73.
上記ピストン部材７４は、従来公知の如く、ステムＦ２側から高圧液体が流入すると、大径ピストン部７８及び小径ピストン部７６の径の差により、小径ピストン部７６の後面に作用する液圧に比べて大径ピストン部７８の前面に作用する液圧が大となることで、第２弁座ｖ２ｓに対してピストン部材７４が後退し、第２逆止弁Ｖ２が開き、高圧液体の流入が解消されると、スプリング７９の弾性復元力により第２逆止弁Ｖ２が閉じるように構成している。 As is known in the art, when high pressure liquid flows in from the stem F 2 side, the piston member 74 has a hydraulic pressure acting on the rear surface of the small diameter piston portion 76 due to the difference in diameter between the large diameter piston portion 78 and the small diameter piston portion 76. by hydraulic pressure acting on the front face of the large-diameter piston section 78 than is large, the piston member 74 is retracted relative to the second valve seat v 2s, the second check valve V 2 is opened, the high pressure liquid When the inflow is eliminated, the second check valve V <b> 2 is closed by the elastic restoring force of the spring 79.
これまでに述べた構成に関して、図１に示す正立状態からトリガー部３８を引くと、第１枢着部３４を中心にトリガー付き部材Ｄが回転することで、第２枢着部３７を介して作動部材Ｆが下降する。そうするとシリンダＡ内部が加圧されることで、第１逆止弁Ｖ１が閉じ、シリンダＡ内の液体がステムＦ２を介してヘッド部Ｆ３内へ流入し、第２逆止弁Ｖ２が開く。そしてノズル７２から液体が噴出される。トリガー部３８を解放すると、スプリング２０の弾性復元力により筒状ピストンＦ１が上昇し、第１逆止弁Ｖ１が開く。そうすると合流口５６が負圧化して、正立状態では、一方の流路切替弁Ｖ３が開くとともに、他方の流路切替弁Ｖ４が閉じる。これにより正立時用吸込口ｏ１からシリンダＡ内へ液体が吸い込まれる。容器体１０２内が負圧化すると、空気流路ｐＡを介して外気が容器体１０２内に導入される。また倒立状態では、一方の流路切替弁Ｖ３が閉じるとともに、他方の流路切替弁Ｖ４が開く。これにより倒立時用吸込口ｏ２からシリンダＡ内へ液体が吸い込まれる。 With regard to the configurations described so far, when the trigger portion 38 is pulled from the upright state shown in FIG. 1, the member D with the trigger rotates around the first pivot portion 34, thereby allowing the second pivot portion 37 to be interposed. Thus, the operating member F is lowered. Then, the inside of the cylinder A is pressurized, the first check valve V 1 is closed, the liquid in the cylinder A flows into the head portion F 3 through the stem F 2 , and the second check valve V 2. Opens. Then, liquid is ejected from the nozzle 72. Upon release of trigger 38, the cylindrical piston F 1 is increased by the elastic restoring force of the spring 20, the first check valve V 1 is opened. Then joined gate 56 is negative pressure, in the erected state, the open one flow path switching valve V 3, the other flow path switching valve V 4 is closed. As a result, the liquid is sucked into the cylinder A from the upright suction port o 1 . When the container body 102 is negative pressure, outside air is introduced into the container body 102 through the air flow path p A. In the inverted state, with closing one flow path switching valve V 3, open the other flow path switching valve V 4. Thus the liquid is drawn from the standing time of suction port o 2 into the cylinder A.
弾性パッキンＧは、リング板状の部材であり、その外周部８４を延長筒部３と環状段部２８との間に挟持されることで支承されている。好適な図示例では、上記環状圧接リブ２８ａを上記弾性パッキンＧの外周部８４に食い込ませることで挟持力を高めている。そして弾性パッキンＧは、その挟持箇所を支点として、内周部８６の昇降可能に弾性屈曲することができる。図４に示すように正立状態での弾性パッキンＧの内周部８６の下側には弾性パッキンＧの屈曲変形を可能とするための空隙ｓが形成されている。 The elastic packing G is a ring plate-like member, and is supported by sandwiching the outer peripheral portion 84 between the extension tube portion 3 and the annular step portion 28. In a preferred illustrated example, the clamping force is increased by causing the annular pressure-contact rib 28 a to bite into the outer peripheral portion 84 of the elastic packing G. The elastic packing G can be elastically bent so that the inner peripheral portion 86 can be raised and lowered with the sandwiched portion as a fulcrum. As shown in FIG. 4, a gap s for allowing the elastic packing G to be bent and deformed is formed below the inner peripheral portion 86 of the elastic packing G in the upright state.
弾性パッキンＧは或る程度の厚みを有し、その内周部８６側の周端部をステムＦ２の垂直筒部６２ａ外周面に液密に当接することで、倒立時に上記空気流路ｐＡを介して液体が漏れだすことを防止する。 Elastic gasket G has a thickness of about one, by abutting the peripheral edge portion of the inner peripheral portion 86 side to the liquid-tight to the vertical tubular portion 62a outer peripheral surface of the stem F 2, the air flow path p when inverted Prevent liquid from leaking through A.
上記弾性パッキンＧの内周部８６には、弾性パッキンＧの弾性屈曲に伴い垂直筒部６２ａとの間からの空気の流通を可能とする空気逃がし溝９０を形成する。好適な図示例では、弾性パッキンＧの内周部８６の上角部８８を切り欠いて、上記空気逃がし溝９０を形成している。すなわち、図４に示す如く、弾性パッキンＧの厚みのうち下端側の一部をシール代ｄとして残して上側の部分を切り欠いている。好適な図示例では、弾性パッキンＧの内周部８６に、周方向に間欠的に複数の空気逃がし溝９０を形成している。もっともこの構造は適宜変更することができる。 In the inner circumferential portion 86 of the elastic packing G, an air escape groove 90 that allows air to flow from and to the vertical cylindrical portion 62a as the elastic packing G is elastically bent is formed. In a preferred illustrated example, the air escape groove 90 is formed by cutting out the upper corner 88 of the inner peripheral portion 86 of the elastic packing G. That is, as shown in FIG. 4, the upper portion is cut away while leaving a part of the lower end side of the thickness of the elastic packing G as a seal allowance d. In a preferred illustrated example, a plurality of air escape grooves 90 are intermittently formed in the inner circumferential portion 86 of the elastic packing G in the circumferential direction. However, this structure can be changed as appropriate.
上記構成において、図４の状態から液体吐出器を上下逆向きにしても、図８に太い矢印で示すように空気流路ｐＡを液体が逆流しても弾性パッキンＧの内周部で液漏れを阻止することができる。その理由は、第１に、上述の如く弾性パッキンＧの内周部８６が上記シール代ｄの幅だけ垂直筒部６２ａに密接しているから、弾性パッキンＧは環状段部２８と当接しており、液体の流れ方向（図８での下方向）に弾性変形する余地がないからである。 In the above structure, even when from the state of FIG. 4 the liquid dispenser upside down, liquid in the inner peripheral portion of even the elastic packing G to flow back to the air flow path p A liquid as indicated by the thick arrow in FIG. 8 Leakage can be prevented. The reason is that, as described above, since the inner peripheral portion 86 of the elastic packing G is in close contact with the vertical cylindrical portion 62a by the width of the seal allowance d, the elastic packing G is in contact with the annular step portion 28. This is because there is no room for elastic deformation in the liquid flow direction (downward in FIG. 8).
他方、作動部材Ｆの昇降により容器体１０２内部が負圧化すると、弾性パッキンＧが下方へ弾性屈曲する。このとき空気逃がし溝９０の形成箇所以外の上角部８８が図７に示すように垂直筒部６２ａに当接するので、空気逃がし溝９０の底部と垂直筒部６２ａとの間に距離を確保することができ、確実に空気を逃がすことができる。 On the other hand, when the inside of the container body 102 becomes negative pressure by raising and lowering the operation member F, the elastic packing G is elastically bent downward. At this time, since the upper corner portion 88 other than the portion where the air escape groove 90 is formed contacts the vertical cylinder portion 62a as shown in FIG. 7, a distance is secured between the bottom portion of the air escape groove 90 and the vertical cylinder portion 62a. Can be surely escaped.
