Description
本発明は、正倒立両用液体吐出器及び正倒立両用吐出容器に関する。 The present invention relates to a normal inverted liquid discharger and a normal inverted discharge container.
従来、この種の吐出器として、
容器体の口頸部への嵌合するキャップ状の装着部材と、
この装着部材を介して容器体内へ垂下するシリンダと、
シリンダ内部から装着部材の頂部を貫通して起立するステムの上端にノズルヘッドを付設してなる作動部材とを具備し、
装着部材の周壁から上方へ支持片を延長するとともに、この支持片の上端に基端部を枢着したトリガーを上記ノズルヘッドに連係して、トリガーの操作により作動部材を上下動して液体を吐出可能に設けた吐出器において、
上記シリンダの下部外面に、正立時用吸込み口及び倒立時用吸込み口を備えた２方向流路アダプタを備えたものが用いられている。
Conventionally, as this kind of dispenser,
A cap-shaped mounting member that fits into the mouth and neck of the container body;
A cylinder that hangs into the container through the mounting member;
An actuating member having a nozzle head attached to the upper end of a stem that stands up from the inside of the cylinder through the top of the mounting member;
A support piece is extended upward from the peripheral wall of the mounting member, and a trigger having a base end pivotally attached to the upper end of the support piece is linked to the nozzle head, and the operation member is moved up and down by the operation of the trigger. In the dispenser provided to allow discharge,
A cylinder provided with a two-way flow path adapter having an upright suction port and an inverted suction port on the lower outer surface of the cylinder is used.
こうした吐出器は、液体の取り出しによる容器体内部の負圧化を解消するために、外気導入路を装着部材の適所に設けておくことが一般的である。しかしながら、倒立操作により容器体内の液体が外気導入路内へ逆流する可能性がある。
そこでこうした不都合を回避するために、上記装着部材の頂部の内周部を***させて上記ステムを昇降可能に保持する保持筒とするとともに、この保持筒内面に下向き段部を周設し、この下向き段部へ向けてシリンダの周壁を延長して延長壁部の上端と下向き段部との間に弾性リングで形成する逆流防止弁を挟持させたものが知られている（特許文献１)。
In order to eliminate the negative pressure inside the container body due to the liquid being taken out, such a discharger is generally provided with an outside air introduction path at an appropriate position of the mounting member. However, there is a possibility that the liquid in the container flows backward into the outside air introduction path due to the inversion operation.
Therefore, in order to avoid such inconvenience, the inner peripheral portion of the top portion of the mounting member is raised to form a holding cylinder that holds the stem so that it can be raised and lowered, and a downward stepped portion is provided around the inner surface of the holding cylinder. A cylinder in which a peripheral wall of a cylinder is extended toward a downward step portion and a backflow prevention valve formed by an elastic ring is sandwiched between the upper end of the extension wall portion and the downward step portion is known (Patent Document 1).
特許文献１のものは、保持筒部の下向き段部と延長壁部の先端部との間に弾性リングを挟持させて逆流防止弁を形成しているから、ポンプ機構の組み立て作業が面倒であった。 In Patent Document 1, the backflow prevention valve is formed by sandwiching an elastic ring between the downward step portion of the holding cylinder portion and the distal end portion of the extension wall portion, so that the assembly work of the pump mechanism is troublesome. It was.
本発明の目的は、ポンプ機構のシリンダ外面に取り付けた流路アダプタに逆流防止弁を組み込み、簡易に組み立てることができる正倒立両用液体吐出器及び正倒立両用吐出容器を提案することである。 An object of the present invention is to propose a normal inverted liquid discharger and a normal inverted discharge container that can be easily assembled by incorporating a backflow prevention valve into a flow path adapter attached to the cylinder outer surface of a pump mechanism.
第１の手段は、正倒立両用液体吐出器であって、
容器体１０２の口頸部１０４上面への係止用の外向きフランジ４の内周部に、内部に第１逆止弁Ｖ１を設けたシリンダ周壁２を連設したシリンダＡと、

A backflow prevention valve G is formed outside the vent hole h.
本手段では、図１に示すように、正倒立用の２方向流路アダプタＥに逆流防止弁Ｇを組み込むことで、液体吐出器全体の組立工程を簡素化するようにしている。またポンプ機構の内部に逆流防止弁を付設しないので、正倒立仕様の本願液体吐出器を、通常仕様の液体吐出器と同様の組立手順で作製できる。 In this means, as shown in FIG. 1, the assembly process of the entire liquid ejector is simplified by incorporating the backflow prevention valve G into the two-way flow path adapter E for normal inversion. In addition, since the backflow prevention valve is not provided inside the pump mechanism, the liquid ejector of the present invention with the upside-down specification can be produced by the same assembly procedure as the liquid ejector with the normal specification.
第２の手段は、第１の手段を有し、かつ
上記逆流防止弁Ｇは、外周壁４２の上部の外側へ弾性弁筒１６ａを含む弁部材１６を取り付けることで形成され、
弾性弁筒１６ａは筒壁下端の拡開が可能に筒壁上部を外周壁４２の上部外面へ嵌着させ、外周壁４２の通気孔ｈ形成箇所を覆うように構成している。
The second means includes the first means, and the backflow prevention valve G is formed by attaching the valve member 16 including the elastic valve cylinder 16a to the outside of the upper portion of the outer peripheral wall 42,
The elastic valve cylinder 16a is configured such that the upper end of the cylinder wall is fitted to the upper outer surface of the outer peripheral wall 42 so that the lower end of the cylinder wall can be expanded, and the portion of the outer peripheral wall 42 where the vent hole h is formed is covered.
本手段では、図１に示すように、逆流防止弁形成用の弁部材１６が有する弾性弁筒１６ａの下半部で、２方向流路アダプタＥの外周壁４２の通気孔ｈ形成箇所を覆うとともに、弾性弁筒１６ａの上半部を外周壁４２に嵌着するようにしている。これにより、シリンダＡに２方向流路アダプタＥを取り付ける前からアダプタと弁部材１６とを予め一体化することができ、組立作業が簡単である。 In this means, as shown in FIG. 1, the lower half portion of the elastic valve cylinder 16a of the valve member 16 for forming the backflow prevention valve covers the place where the vent hole h is formed in the outer peripheral wall 42 of the two-way flow path adapter E. At the same time, the upper half of the elastic valve cylinder 16 a is fitted to the outer peripheral wall 42. Thereby, before attaching the two-way flow path adapter E to the cylinder A, the adapter and the valve member 16 can be integrated in advance, and the assembling work is simple.
第３の手段は、第２の手段を有し、かつ
上記外周壁４２は、周壁本体４２ａから段差部４２ｂを介して外周壁４２の上部である大径筒部４２ｃを起立するとともに、段差部４２ｂに上記通気孔ｈを開口しており、
上記弾性弁筒１６ａの少なくとも下半部は下方小径のテーパ状に形成されており、弾性弁筒の下端部を上記周壁本体４２ａの外面に当接させることで逆流防止弁Ｇを形成している。
The third means includes the second means, and the outer peripheral wall 42 stands up from the peripheral wall main body 42a through the stepped portion 42b and a large-diameter cylindrical portion 42c that is the upper portion of the outer peripheral wall 42, and the stepped portion. 42b opens the vent hole h,
At least the lower half portion of the elastic valve cylinder 16a is formed in a tapered shape having a small lower diameter, and the backflow prevention valve G is formed by bringing the lower end portion of the elastic valve cylinder into contact with the outer surface of the peripheral wall body 42a. .
本手段では、図２に示すように、外周壁４２の上部である大径筒部４２ｃと周壁本体４２ａとの間の段差部４２ｂに通気孔ｈを開口し、弾性弁筒１６ａの少なくとも下半部は下方小径のテーパ状に形成されており、弾性弁筒１６ａの下端部を上記周壁本体４２ａの外面に当接させることを提案している。この構成であると、容器体が負圧化したときに弾性弁筒１６ａの下半部は容易に拡開して外気の導入を可能とし、また容器体を倒立状態とすると容器体内の液圧により弾性弁筒の下半部を周壁本体４２ａに圧接させるから、逆流防止も確実となる。 In this means, as shown in FIG. 2, a vent hole h is opened in the stepped portion 42b between the large-diameter cylindrical portion 42c and the peripheral wall body 42a, which is the upper portion of the outer peripheral wall 42, and at least the lower half of the elastic valve cylinder 16a. The part is formed in a tapered shape with a small diameter on the lower side, and it is proposed that the lower end portion of the elastic valve cylinder 16a is brought into contact with the outer surface of the peripheral wall body 42a. With this configuration, when the container body is negatively pressurized, the lower half of the elastic valve cylinder 16a is easily expanded to allow introduction of outside air, and when the container body is inverted, the fluid pressure in the container body As a result, the lower half of the elastic valve cylinder is brought into pressure contact with the peripheral wall main body 42a, so that backflow prevention is also ensured.
第４の手段は、
口頸部１０４を起立する容器体１０２と、第２の手段又は第３の手段に記載の正倒立両用液体吐出器１とで構成される正倒立両用容器であって、
上記正倒立両用液体吐出器１は、上記口頸部の外面への嵌合用の装着筒部２２の上端より、上方から見て中央部に挿通口ｍを有する頂部２４を延設した装着部材Ｃを有し、
上記外周壁４２の上端に付設した環状板部４２ｄを、外向きフランジ４の下に、また上記弾性弁筒１６ａの上端部に付設した鍔部１６ｂを環状板部４２ｄの下にそれぞれ重ねて、これら外向きフランジ４と環状板部４２ｄと鍔部１６ｂとが口頸部１０４の上面と頂部２４との間に挟持されるように設けている。
The fourth means is
A container for standing upright and upright, which is composed of the container body 102 for standing up the mouth and neck 104 and the liquid dispenser 1 for upside-down use described in the second means or the third means,
The upside-down dual-use liquid ejector 1 has a mounting member C in which a top portion 24 having an insertion port m is extended from the upper end of the mounting cylinder portion 22 for fitting to the outer surface of the mouth and neck portion as viewed from above. Have
The annular plate portion 42d attached to the upper end of the outer peripheral wall 42 is overlaid under the outward flange 4, and the flange portion 16b attached to the upper end portion of the elastic valve tube 16a is overlaid under the annular plate portion 42d. The outward flange 4, the annular plate portion 42 d, and the flange portion 16 b are provided so as to be sandwiched between the upper surface of the mouth and neck portion 104 and the top portion 24.
本手段では、図２に示すように、装着部材Ｃを容器体１０２の口頸部１０４へ装着したときに、シリンダＡの外向きフランジ４と２方向流路アダプタＥの環状板部４２ｄと弾性弁筒１６ａの鍔部１６ｂとが３層状に重ねられ、口頸部１０４の上端と装着部材Ｃの頂部２４との間に挟持されるようにしている。この構成によると、単に２方向流路アダプタＥ及び弾性弁筒１６ａの脱落が防止できるだけでなく、２方向流路アダプタＥと弾性弁筒１６ａとの位置関係が一義的に決まり、通気孔ｈと弾性弁筒１６ａとの位置合わせをする必要がないので、組立作業が容易となる。 In this means, as shown in FIG. 2, when the mounting member C is mounted on the mouth-and-neck portion 104 of the container body 102, the outward flange 4 of the cylinder A and the annular plate portion 42 d of the two-way flow channel adapter E are elastic. The flange portion 16b of the valve cylinder 16a is stacked in three layers so as to be sandwiched between the upper end of the mouth-and-neck portion 104 and the top portion 24 of the mounting member C. According to this configuration, not only can the two-way flow path adapter E and the elastic valve cylinder 16a be prevented from falling off, but also the positional relationship between the two-way flow path adapter E and the elastic valve cylinder 16a is uniquely determined. Since it is not necessary to align with the elastic valve cylinder 16a, assembly work is facilitated.
第１の手段に係る発明によれば、流路アダプタＥに逆流防止弁を組み込んだので、全体の組み立て作業を簡素化することができる。またポンプの内部に逆流防止弁を組み込む従来品と比較して、正倒立仕様と通常仕様とでポンプの組立て作業が変わってくることがないので、便利である。
第２の手段に係る発明によれば、弁部材１６の弾性弁筒１６ａの上半部を外周壁に嵌着させたから、２方向流路アダプタＥをシリンダＡに装着する前の段階から、逆流防止弁をシリンダＡに組み込むことができ、組立作業が容易となる。
第３の手段に係る発明によれば、２方向流路アダプタＥは、外周壁４２の周壁本体４２ａから通気孔ｈ付きの段差部４２ｂを介して大径筒部４２ｃを起立したから、簡易な構成でありながら外気の導入と液体の逆流防止とを確実に機能させることができる。
第４の手段に係る発明によれば、口頸部１０４の上面と頂部２４との間にシリンダＡの外向きフランジ４と２方向流路アダプタＥの環状板部４２ｄと弁部材１６の鍔部１６ｂとが挟持されるようにしたから、シリンダＡと２方向流路アダプタＥと弁部材１６とを簡易に結合することができる。
According to the invention relating to the first means, since the backflow prevention valve is incorporated in the flow path adapter E, the entire assembly work can be simplified. Also, compared to conventional products that incorporate a backflow prevention valve inside the pump, the assembly work of the pump does not change between the normal inverted specification and the normal specification, which is convenient.
According to the second aspect of the invention, since the upper half portion of the elastic valve cylinder 16a of the valve member 16 is fitted to the outer peripheral wall, the reverse flow starts from the stage before the two-way flow path adapter E is attached to the cylinder A. The prevention valve can be incorporated in the cylinder A, and the assembling work becomes easy.
According to the invention relating to the third means, the two-way flow path adapter E stands up from the peripheral wall main body 42a of the outer peripheral wall 42 via the stepped portion 42b with the vent hole h, so that it is simple. In spite of the configuration, the introduction of the outside air and the prevention of the back flow of the liquid can be surely functioned.
According to the invention relating to the fourth means, the outward flange 4 of the cylinder A, the annular plate portion 42d of the two-way flow channel adapter E, and the flange portion of the valve member 16 between the upper surface of the mouth-and-neck portion 104 and the top portion 24. Since 16b is clamped, the cylinder A, the two-way flow path adapter E, and the valve member 16 can be easily combined.

作動部材Ｆは、筒状ピストンＦ１と、ステムＦ２と、ヘッド部Ｆ３とで構成されている。 The operating member F includes a cylindrical piston F1, a stem F2, and a head portion F3.
上記筒状ピストンＦ１は、内筒部及び外筒部からなる２重筒状であって、ステムＦ２の下端部に付設されており、かつシリンダ周壁２内に摺接されている。筒状ピストンＦ１と上記脚片１８との間にはスプリング２０を介装する。 The cylindrical piston F <b> 1 has a double cylindrical shape including an inner cylindrical portion and an outer cylindrical portion, is attached to the lower end portion of the stem F <b> 2, and is in sliding contact with the cylinder peripheral wall 2. A spring 20 is interposed between the cylindrical piston F1 and the leg piece 18.
上記ステムＦ２は、全体として略逆Ｌ字形であり、図２に示す如く、垂直筒部６２ａの上端から水平筒部６２ｂを前方突出してなる。垂直筒部６２ａは、筒状ピストンＦ１から保持筒部２６の上半部２６ｂ内部を通って上方へ突出している。上記保持筒部２６の上半部２６ｂと垂直筒部６２ａとの間には図１に示す如く間隙６１が形成されている。この間隙６１と上記延長筒部３の縦溝部３ａと外向きフランジ４の連通孔６とは空気流路ＰＡを形成する。上記水平筒部６２ｂは、図２に示す如く、後半部から前向きの係止段部６３を介しての前半部を突出しており、その前半部は前端大径の拡開筒部６４に形成している。上記係止段部６３と後述のピストン部材７４との間にはスプリング７９を介装させる。 The stem F2 has a substantially inverted L shape as a whole, and is formed by projecting the horizontal cylinder part 62b forward from the upper end of the vertical cylinder part 62a as shown in FIG. The vertical cylinder part 62a protrudes upward from the cylindrical piston F1 through the inside of the upper half part 26b of the holding cylinder part 26. A gap 61 is formed between the upper half part 26b of the holding cylinder part 26 and the vertical cylinder part 62a as shown in FIG. The gap 61, the vertical groove 3a of the extension cylinder 3 and the communication hole 6 of the outward flange 4 form an air flow path PA. As shown in FIG. 2, the horizontal cylinder part 62b protrudes from the latter half part through the forward locking step part 63, and the front half part is formed in an enlarged cylinder part 64 having a large front end. ing. A spring 79 is interposed between the locking step 63 and a piston member 74 described later.
上記ヘッド部Ｆ３は、本実施形態において、図２に示す如く、横棒部材６６と、キャップ７０と、ピストン部材７４とを有する。
もっともヘッド部Ｆ３の構造は適宜変更することができ、例えば別体で設けていた吐出口（ノズル７２）を、ヘッド部に吐出口を有する一体の構造として形成してもよい。
In the present embodiment, the head portion F3 includes a horizontal bar member 66, a cap 70, and a piston member 74 as shown in FIG.
However, the structure of the head portion F3 can be changed as appropriate. For example, the discharge port (nozzle 72) provided separately may be formed as an integral structure having the discharge port in the head portion.
上記横棒部材６６は、上記水平筒部６２ｂ内に挿入され、長手方向中間部に付設した複数の係止片６８を、上記係止段部６３に当接可能に形成している。 The horizontal bar member 66 is inserted into the horizontal cylindrical portion 62b and is formed with a plurality of locking pieces 68 attached to the intermediate portion in the longitudinal direction so as to be able to contact the locking step portion 63.
上記キャップ７０は、吐出口であるノズル７２を開口した前壁を有し、この前壁の周縁部から後方突出する筒壁部を、上記拡開筒部６４の外面に嵌合させている。また上記筒壁部の前部を、段差部７３を介して縮径する小内径部とし、この小内径部に第２弁座Ｖ２ｓを形成している。 The cap 70 has a front wall that opens a nozzle 72 that is a discharge port, and a cylindrical wall portion that protrudes rearward from the peripheral edge portion of the front wall is fitted to the outer surface of the expanded cylindrical portion 64. 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 a second valve seat V2s is formed in the small inner diameter portion.
上記ピストン部材７４は、前後方向の筒体７５の後端部を、拡開筒部６４の後部内面に接する小径ピストン部７６とし、筒体７５の前端部を、上記第２弁座Ｖ２ｓに接する第２弁体Ｖ２ｂとしている。第２弁座Ｖ２ｓと第２弁体Ｖ２ｂとで第２逆止弁Ｖ２を形成している。また上記筒体７５の長手方向中間部に透孔７７を開口して、透孔７７後方の筒体部分から前端大径のテーパ形状である大径ピストン部７８を突出する。大径ピストン部７８は、段差部７３後方のキャップ筒壁部分に接している。 The piston member 74 has a rear end portion of the cylinder 75 in the front-rear direction as a small-diameter piston portion 76 that is in contact with the inner surface of the rear portion of the expanded cylinder portion 64, and a front end portion of the cylinder 75 is in contact with the second valve seat V2s. The second valve body V2b is used. The second valve seat V2s and the second valve body V2b form a second check valve V2. 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, the piston member 74 is compared with the 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 when high pressure liquid flows from the stem F2 side. As the hydraulic pressure acting on the front surface of the large-diameter piston portion 78 becomes large, the piston member 74 moves backward relative to the second valve seat v2s, the second check valve V2 opens, and the inflow of high-pressure liquid is eliminated. Then, the second check valve V2 is configured to be 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。そうすると共通口部５６が負圧化して、正立状態では、流路切替弁Ｖ３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、流路切替弁Ｖ３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, whereby the first check valve V1 is closed, the liquid in the cylinder A flows into the head portion F3 through the stem F2, and the second check valve V2 is opened. Then, liquid is ejected from the nozzle 72. When the trigger portion 38 is released, the cylindrical piston F1 is raised by the elastic restoring force of the spring 20, and the first check valve V1 is opened. If it does so, the common port part 56 will become negative pressure, and the flow-path switching valve V3 will close in an erect state. As a result, the liquid is sucked into the cylinder A from the upright suction port O1. When the inside of the container body 102 becomes negative pressure, outside air is introduced into the container body 102 through the air flow path PA. In the inverted state, the flow path switching valve V3 is opened. Thereby, the liquid is sucked into the cylinder A from the suction port O2 for inversion.
本発明においては、２方向流路アダプタＥの外周壁４２を外向きフランジ４側へ延長している。外周壁４２は、周壁本体４２ａから段差部４２ｂを介して外周壁の上部である大径筒部４２ｃを起立し、大径筒部４２ｃの上端から環状板部４２ｄを外方へ突出してなる。そしてこの環状板部４２ｄを外向きフランジ４の下面に突き当てた状態で、上記周壁本体４２ａの上部がシリンダＡ外面に嵌着されるように設ける。 In the present invention, the outer peripheral wall 42 of the two-way flow path adapter E is extended to the outward flange 4 side. The outer peripheral wall 42 has a large-diameter cylindrical portion 42c that is an upper portion of the outer peripheral wall through a stepped portion 42b from the peripheral wall main body 42a, and an annular plate portion 42d that protrudes outward from the upper end of the large-diameter cylindrical portion 42c. Then, the upper portion of the peripheral wall main body 42 a is provided so as to be fitted to the outer surface of the cylinder A in a state where the annular plate portion 42 d is abutted against the lower surface of the outward flange 4.
また、外周壁４２には、上記段差部４２ｂを垂直方向に貫通する通気孔ｈを設ける。こうすることで、第１筒状部材Ｅ１を金型成形するときに型抜きが容易となる。 The outer peripheral wall 42 is provided with a vent hole h penetrating the stepped portion 42b in the vertical direction. By doing so, it is easy to remove the mold when the first cylindrical member E1 is molded.
上記外周壁４２の上半部には、逆流防止弁形成用の弁部材１６を取り付ける。弁部材１６は、弾性弁筒１６ａの上端に鍔部１６ｂを付設してなる。この鍔部１６ｂと、外周壁４２の環状板部４２ｄと、外向きフランジ４とは、ほぼ同外径であり、図１に示すように３層に重ねて、口頸部１０４の上面と装着部材Ｃのフランジ状頂壁部２５との間に挟持されている。鍔部１６ｂは弾性を有し、上記挟持状態でパッキンとしても作用する。 A valve member 16 for forming a backflow prevention valve is attached to the upper half of the outer peripheral wall 42. The valve member 16 is formed by attaching a flange 16b to the upper end of the elastic valve cylinder 16a. The flange portion 16b, the annular plate portion 42d of the outer peripheral wall 42, and the outward flange 4 have substantially the same outer diameter, and are attached to the upper surface of the mouth / neck portion 104 so as to overlap three layers as shown in FIG. It is sandwiched between the flange-like top wall portion 25 of the member C. The flange portion 16b has elasticity, and also functions as a packing in the sandwiched state.
上記弾性弁筒１６ａは、筒壁の下半部を下端小径のテーパ状とするとともに、筒壁の上部を上記大径筒部４２ｃの外面に嵌着させている。この状態で弾性弁筒１６ａの先端部（下端部)は、周壁本体４２ａの外面に弾性的に圧接している。 The elastic valve cylinder 16a has a lower half portion of the cylindrical wall having a tapered shape with a small diameter at the lower end, and an upper portion of the cylindrical wall is fitted to the outer surface of the large diameter cylindrical portion 42c. In this state, the distal end portion (lower end portion) of the elastic valve cylinder 16a is elastically pressed against the outer surface of the peripheral wall body 42a.
この構成によれば、正立状態でトリガー部３８を操作して液体を吐出し、容器体１０２内が負圧化されたときには、図２に点線で示すように弾性弁筒１６ａの下半部が弾性的に拡開して、外気が挿通口ｍから空気通路ＰＡを経由して、容器体内へ入る。これにより負圧状態が緩和される。 According to this configuration, when the trigger unit 38 is operated in the upright state to discharge the liquid and the inside of the container body 102 is made negative pressure, the lower half of the elastic valve cylinder 16a is shown by the dotted line in FIG. Expands elastically, and outside air enters the container body through the air passage PA from the insertion port m. This alleviates the negative pressure state.
次に倒立状態としたときには、容器体の液体が口頸部１０４側へ集まり、図３に矢印で示すように弾性弁筒１６ａの外面に液圧が作用するため、弾性弁筒１６ａの先端部が一層周壁本体４２ａに圧接されることになる。これにより液体の逆流防止がより効果的に実現する。 Next, in the inverted state, the liquid in the container body gathers toward the mouth-and-neck portion 104, and the hydraulic pressure acts on the outer surface of the elastic valve cylinder 16a as shown by the arrow in FIG. Is further pressed against the peripheral wall body 42a. Thereby, the backflow prevention of the liquid is realized more effectively.
以下、本発明の他の実施形態について説明する。これらの実施形態の説明において第１実施形態と同じ構成については、解説を省略する。 Hereinafter, other embodiments of the present invention will be described. In the description of these embodiments, the description of the same configuration as that of the first embodiment is omitted.
