Description

本発明はポンプ用の容器体に関する。   The present invention relates to a container for a pump.

有底筒状の胴部より肩部を介して口頸部を起立した形態をなし、口頸部に装着したポンプの操作により収容液を汲み上げてポンプの吐出口より吐出する如く構成したポンプ容器が種々提案されている。（例えば、特許文献１参照）   A pump container constructed such that the mouth and neck are raised from the bottomed cylindrical body through the shoulder, and the stored liquid is pumped up by the operation of the pump attached to the mouth and neck and discharged from the discharge port of the pump. Various proposals have been made. (For example, see Patent Document 1)

これらのポンプ容器に使用されている容器体として、例えば、特許文献１に記載された容器体は、有底筒状の胴部の上端より肩部を介して口頸部を起立し、全体を一体に形成している。また、底部は中央部が***してその周縁部に環状の凹部が存在する形態をなしている。これらの容器体は一般にブロー成形により形成される場合が多く、その場合底部のピンチオフによりその中央が***する傾向となる。
特開平０８−２３０９６１号公報 As a container body used in these pump containers, for example, the container body described in Patent Document 1 stands up from the upper end of the bottomed cylindrical trunk portion through the shoulder portion, and the entire body. It is integrally formed. Moreover, the bottom part has the form which the center part protrudes and the cyclic | annular recessed part exists in the peripheral part. In general, these container bodies are often formed by blow molding, in which case the center tends to rise due to pinch-off at the bottom.
Japanese Patent Laid-Open No. 08-230961

上記した特許文献１にある如き一般的なポンプ用容器体は、生産性の良さ或いはコストの低減を図る等の目的でブロー成形により形成されるものが好ましく、その場合上記した底部中央部が***する傾向があるため、その周囲の環状の凹部に残液が生じる虞があった。これらの容器体に使用するポンプは、容器体内に吸上げ用のパイプを垂下させ、その下端を底面近傍に開口してそこから液を吸い上げる如く構成している。吸上げ用のパイプの開口が***部分上であれば***部分周囲の液はそのまま残液となり、また、吸上げ用のパイプを弯曲させてその先端を容器体底部縁部に開口する如く構成した場合でも、パイプの先端角度或いはパイプの太さ、或いは***部分周縁部の溝の幅などの関連で、溝部分に液が残る結果を招く場合が多々あった。   The above-described general pump container as disclosed in Patent Document 1 is preferably formed by blow molding for the purpose of improving productivity or reducing cost, and in this case, the bottom center portion is raised. Therefore, there is a possibility that residual liquid may be generated in the annular recess around the periphery. The pumps used in these container bodies are configured such that a suction pipe is suspended in the container body, the lower end thereof is opened near the bottom surface, and the liquid is sucked therefrom. If the suction pipe opening is on the raised part, the liquid around the raised part remains as it is, and the suction pipe is bent so that its tip opens to the bottom edge of the container body. Even in such a case, there are many cases where the liquid remains in the groove portion in relation to the tip angle of the pipe, the thickness of the pipe, or the width of the groove at the peripheral portion of the raised portion.

また、容器体を射出成形等の複雑な形状を現出可能な成形方法で形成すれば、比較的自由な形態の底部を形成でき、残液の解消を図ることができるが、コストがかかり生産性も低下する等の他の問題が生じる。   Moreover, if the container body is formed by a molding method capable of revealing a complicated shape such as injection molding, the bottom portion of a relatively free form can be formed, and the residual liquid can be eliminated. Other problems arise, such as a decrease in performance.

本発明は上記した点に鑑みてなされたもので、ブロー成形等により形成することができ、従来の生産性の良さ或いは廉価なコストを維持できるとともに、残液を極力なくすことができるポンプ用容器体を提案する。   The present invention has been made in view of the above points, and can be formed by blow molding or the like, can maintain the conventional good productivity or low cost, and can eliminate residual liquid as much as possible. Suggest body.

本発明のポンプの容器体は、合成樹脂により一体に形成されたもので、特にブロー成形等による形成が可能である。その形態は、有底筒状の胴部から肩部を介して口頸部を起立した形態であり、少なくとも胴部の下端部を円筒状，楕円筒状或いは多角形筒状等に形成したものである。従って、胴部の上部を下端部の形状と異なる形状にしたものであっても、或いは胴部全体が同一筒状形態のものであっても良い。また、胴部の下端部には反転壁を介して傾斜下降する底壁を備えている。   The container body of the pump of the present invention is integrally formed of synthetic resin, and can be formed by blow molding or the like. The form is a form in which the mouth and neck are raised from the bottomed cylindrical trunk through the shoulder, and at least the lower end of the trunk is formed in a cylindrical shape, an elliptical cylindrical shape, a polygonal cylindrical shape, etc. It is. Therefore, the upper part of the body part may be different from the shape of the lower end part, or the entire body part may have the same cylindrical shape. Moreover, the bottom wall of the trunk is provided with a bottom wall that inclines and descends via an inversion wall.

本発明の容器体は当初、胴部の下端縁より下方へ反転壁を延設し、反転壁の下端縁より底壁形成壁を延設した形態で製造される。反転壁は、胴部の下端縁に連続する上縁と、胴部の下端縁の一端部から対向端部に向かって傾斜下降し、且つ、胴部下端縁と同じ平面視形状をなす下端縁とを備えた筒状形態をなしており、その下端縁より延設された底壁形成壁が傾斜板状に形成されている。要は、反転壁及び底壁形成壁が上方に反転した際に胴部下部に傾斜した底壁が形成される。底壁形成壁の傾斜方向は、胴部が円筒状或いは正多角形筒状の場合には方向は問われないが、胴部が楕円筒状の場合には、長軸或いは短軸に沿った方向に傾斜させる。   The container body of the present invention is initially manufactured in a form in which a reversal wall is extended downward from the lower end edge of the body part and a bottom wall forming wall is extended from the lower end edge of the reversal wall. The inversion wall has an upper edge continuous with the lower end edge of the body part, and a lower end edge that is inclined downward from one end part of the lower end edge of the body part toward the opposite end part and has the same plan view shape as the lower end edge of the body part The bottom wall forming wall extended from the lower end edge is formed in the shape of an inclined plate. In short, when the reversal wall and the bottom wall forming wall are reversed upward, a bottom wall inclined at the lower portion of the trunk is formed. The inclination direction of the bottom wall forming wall is not limited to the direction when the body portion is cylindrical or a regular polygonal cylinder, but when the body portion is an elliptic cylinder, it is along the long axis or the short axis. Tilt in the direction.

そして、上記の如く形成された容器体を、底壁形成壁を押し上げることで、反転壁を上方へ反転させてその外周面を胴部の内周面下端部に当接させるとともに、底壁形成壁が回動上昇して上げ底状の底壁を形成する。従って、液が少なくなると底壁の下方に液がたまる仕掛けとなっている。そのため、使用するポンプも後述する如き特徴を備えたものが必要となる。   Then, by pushing up the bottom wall forming wall of the container body formed as described above, the inversion wall is inverted upward so that the outer peripheral surface comes into contact with the lower end portion of the inner peripheral surface of the trunk portion, and the bottom wall is formed. The wall rotates and rises to form a raised bottom wall. Therefore, when the amount of liquid is reduced, the liquid is accumulated under the bottom wall. Therefore, the pump to be used is required to have the characteristics as described later.

反転壁の反転機構としては、反転が可能な程度に反転壁の肉厚を調整すれば良く、例えば、胴部或いは底壁形成壁の厚みと比較して薄肉に形成することで容易な反転が可能となる。尚、胴部或いは底壁形成壁の厚みとしては一般的な合成樹脂ボトルの厚みを対象とする。また、反転壁の厚みをごく薄く形成すると反転後の反転壁の強度、例えば容器体内に液を注入した際の圧力等に対抗する強度に問題が生じる虞がある。本発明では、反転した底壁が傾斜して胴部の横断面積よりやや大きい面積を備えているため、底壁の周縁部と胴部内周との接触縁で上方からの圧力を支持する作用もあり、反転壁を比較的薄く構成しても充分強度を現出できる。反面、反転時に底壁形成壁を強制的に押し上げる必要もある。また、胴部底壁部が多角形筒状の場合にはコーナー部分を他の部分と比較して薄肉に形成することで、より反転し易くなる。   As the reversing mechanism of the reversing wall, it is only necessary to adjust the thickness of the reversing wall to the extent that reversal is possible. It becomes possible. Note that the thickness of the body or bottom wall forming wall is the thickness of a general synthetic resin bottle. In addition, if the thickness of the reversal wall is made very thin, there is a possibility that a problem may arise in the strength of the reversal wall after reversal, for example, the strength against the pressure when the liquid is injected into the container. In the present invention, since the inverted bottom wall is inclined and has an area slightly larger than the cross-sectional area of the body portion, the effect of supporting pressure from above at the contact edge between the peripheral edge portion of the bottom wall and the inner periphery of the body portion is also provided. Yes, even if the reversal wall is made relatively thin, sufficient strength can be obtained. On the other hand, it is also necessary to forcibly push up the bottom wall forming wall during reversal. Moreover, when a trunk | drum bottom wall part is a polygonal cylinder shape, it becomes easier to invert by forming a corner part thinly compared with another part.

上記の要件を満たせば反転壁と底壁形成壁との厚さの大小は、それらが上記機能を発揮する中で適宜選択すれば、どちらが厚い場合も同じ場合も可能ではある。   If the above requirements are satisfied, the thicknesses of the reversal wall and the bottom wall forming wall can be selected as long as they exhibit the above functions.

また、本発明の容器体に対応できるポンプとしては、容器体内部に吸上げパイプを垂下させた状態で口頸部に装着し、吸上げパイプより吸引した収容液をポンプの吐出口より吐出する如く構成した公知機構のポンプを採用できる。従って、容器体内の液をそのまま液として吐出口より吐出する場合も、公知の機構により泡として吐出口より吐出する形態のものであっても採用可能である。また、ポンプの吸上げパイプは、中間部で屈曲させる等するとともに、所定の長さに形成して、ポンプを容器体に装着した際にその下端が容器体の底部縁部に、しかも最下方位置の底部縁部に開口する形態のものを採用する。   Moreover, as a pump which can respond to the container body of the present invention, the suction pipe is suspended inside the container body and is attached to the mouth and neck, and the stored liquid sucked from the suction pipe is discharged from the discharge port of the pump. A pump having a known mechanism configured as described above can be employed. Therefore, even when the liquid in the container is directly discharged from the discharge port as a liquid, it is possible to adopt a configuration in which the liquid is discharged from the discharge port as bubbles by a known mechanism. In addition, the pump suction pipe is bent at the middle portion and formed to a predetermined length, and when the pump is mounted on the container body, its lower end is at the bottom edge of the container body, and at the lowest position. The thing of the form opened to the bottom edge part of a position is employ | adopted.

第１の手段として、以下の通り構成した。即ち、有底筒状の胴部10より肩部11を介して口頸部12を起立し、口頸部12に装着したポンプＢの吸上げパイプ26により収容液を吸引し、ポンプＢの吐出口30より吐出するポンプ用の容器体であって、胴部10の下端縁より下方へ反転壁13を延設するとともに、反転壁13の下端開口を閉塞する傾斜板状の底壁形成壁15を反転壁13の下端縁より延設し、反転壁13は、胴部10の下端縁に連続する上縁と、胴部10の下端縁の一端部から対向端部に向かって傾斜下降し、且つ胴部下端縁と同じ平面視形状をなす下端縁とを備えた筒状形態で、底壁形成壁15及び胴部10と比較して薄肉に形成され、胴部10の下端縁を中心に反転壁13を上方へ反転可能に形成し、底壁形成壁15の押し上げにより反転壁13を上方へ反転させてその外周面を胴部10の内周面下端部に当接させるとともに、底壁形成壁15が胴部10の下端縁の一端部を中心に回動上昇して上げ底状の底壁14を形成したことを特徴とするポンプ用の容器体。 The first means is configured as follows. That is, the mouth-and-neck portion 12 is erected from the bottomed cylindrical body portion 10 through the shoulder portion 11, and the stored liquid is sucked by the suction pipe 26 of the pump B attached to the mouth-and-neck portion 12. A container body for a pump that discharges from an outlet 30, and includes an inversion plate 13 extending downward from the lower end edge of the body portion 10 and an inclined plate-like bottom wall forming wall 15 that closes the lower end opening of the inversion wall 13. Extending from the lower end edge of the reversal wall 13, the reversal wall 13 is inclined downward from the upper edge continuous to the lower end edge of the body part 10 and the one end part of the lower end edge of the body part 10 toward the opposite end part, In addition, it has a cylindrical shape with a lower end edge that has the same planar view shape as the lower end edge of the body part, and is formed to be thinner than the bottom wall forming wall 15 and the body part 10, with the lower end edge of the body part 10 as the center When the reversal wall 13 is formed so as to be reversible upward, when the bottom wall forming wall 15 is pushed up, the reversal wall 13 is reversed upward and its outer peripheral surface is brought into contact with the lower end portion of the inner peripheral surface of the trunk portion 10. A bottom wall forming wall 15 container body for pumps, characterized in that the formation of the raised bottom shape of bottom wall 14 around the one end portion of the lower edge rotation rises and the body portion 10.

第２の手段として、以下の通り構成した。即ち、前記第１の手段に於いて、屈曲形成された吸上げパイプ26を備え、口頸部12外周に装着筒23を螺着させることで装着固定するポンプＢに対して、装着筒23の口頸部12への螺着時に、屈曲した吸上げパイプ26の下端開口を底壁14の最下方位置に開口するための位置決め手段を、口頸部12と装着筒23との間に設けた。
The second means is configured as follows. That is, at the first hand stage includes a suction pipe 26 which is bent, the pump B to be attached and fixed by causing screwed mounting cylinder 23 in the neck 12 the outer circumference, the hollow mounting 23 Positioning means for opening the lower end opening of the bent suction pipe 26 to the lowest position of the bottom wall 14 when the screw is screwed to the mouth neck 12 is provided between the mouth neck 12 and the mounting cylinder 23. It was.

本発明によれば、底壁14が傾斜しているため、吸上げパイプ26の下端開口を底壁14の最下方位置に開口すれば、底壁14上に残液が発生することを極力防止でき、しかもブロー成形等により成形してもその構造上の理由で底部中央を***させなければならないという不都合を回避できるため、ブロー成形等による成形が可能で、生産性が良く、低コストでの製造が可能となる。   According to the present invention, since the bottom wall 14 is inclined, if the lower end opening of the suction pipe 26 is opened at the lowest position of the bottom wall 14, it is possible to prevent residual liquid from being generated on the bottom wall 14 as much as possible. In addition, it is possible to avoid the inconvenience of having to raise the center of the bottom for structural reasons even if it is molded by blow molding, etc., so molding by blow molding is possible, productivity is good, and low cost Manufacture is possible.

底壁形成壁15及び胴部10と比較して反転壁13を薄肉に形成した場合には、反転壁13の反転が容易となる利点がある。   When the reversal wall 13 is formed thinner than the bottom wall forming wall 15 and the body portion 10, there is an advantage that the reversal wall 13 can be easily reversed.

屈曲形成された吸上げパイプ26を備え、口頸部12外周に装着筒23を螺着させることで装着固定するポンプＢに対して、装着筒23の口頸部12への螺着時に、屈曲した吸上げパイプ26の下端開口を底壁14の最下方位置に開口するための位置決め手段を、口頸部12と装着筒23との間に設けた場合には、吸上げパイプ26の下端開口を確実容易に底壁14の最下方位置に装着することができる。   The pump B is provided with a bent suction pipe 26 and is mounted and fixed by screwing the mounting cylinder 23 around the outer periphery of the mouth-and-neck section 12, and is bent when the mounting cylinder 23 is screwed to the mouth-and-neck section 12. When the positioning means for opening the lower end opening of the sucked pipe 26 to the lowest position of the bottom wall 14 is provided between the mouth-and-neck portion 12 and the mounting cylinder 23, the lower end opening of the sucked pipe 26 Can be reliably and easily attached to the lowermost position of the bottom wall 14.

以下、本発明の実施例の形態を図面を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１乃至図３は容器体ＡにポンプＢを装着したポンプ容器１の一例を示し、容器体Ａは合成樹脂を使用してブロー成形により一体に形成されたもので、円筒状の胴部10の上端より肩部11を介して口頸部12を起立し、胴部10の下端部には反転壁13を介して底壁14を延設している。   1 to 3 show an example of a pump container 1 in which a pump B is mounted on a container body A. The container body A is integrally formed by blow molding using a synthetic resin, and has a cylindrical body 10. The neck and neck portion 12 is erected from the upper end of the body 10 via the shoulder portion 11, and the bottom wall 14 is extended to the lower end portion of the trunk portion 10 via the inversion wall 13.

容器体Ａは当初図２に示す状態で形成される。図２に於いて、容器体Ａは胴部10の下端縁より下方へ反転壁13を一体に延設し、反転壁13の下端縁より底壁形成壁15を一体に延設している。   The container body A is initially formed in the state shown in FIG. In FIG. 2, the container body A integrally has a reversal wall 13 extending downward from the lower end edge of the body portion 10, and a bottom wall forming wall 15 integrally extends from the lower end edge of the reversal wall 13.

反転壁13は、図２に示す如く、胴部10の下端縁と略同形の円形上縁と、胴部10下端縁の一端部から対向端部に向かって傾斜下降し、且つ、胴部10の下端縁と同じ平面視形状の下端縁とを備えた筒状形態をなし、外周面が胴部10下端部の内周面と略同径程度に形成されている。また、反転壁13は、胴部10及び底壁形成壁15と比較して薄肉に形成している。   As shown in FIG. 2, the reversal wall 13 is inclined downward from one end of the lower end edge of the trunk portion 10 toward the opposite end portion, and is substantially the same as the lower end edge of the trunk portion 10. The outer peripheral surface is formed to have approximately the same diameter as the inner peripheral surface of the lower end portion of the body portion 10. Further, the reversal wall 13 is formed thinner than the body portion 10 and the bottom wall forming wall 15.

底壁形成壁15は、反転壁13の下端縁より、反転壁13の下端開口部を閉塞して、一体に延設した傾斜板状をなしている。この底壁形成壁15は反転壁13が反転した際に、胴部10の下端縁を通る面と対称的に反転して底壁14となる。   The bottom wall forming wall 15 has an inclined plate shape that is integrally extended by closing the lower end opening of the inversion wall 13 from the lower end edge of the inversion wall 13. When the inversion wall 13 is inverted, the bottom wall forming wall 15 is inverted symmetrically with the plane passing through the lower end edge of the body portion 10 to become the bottom wall 14.

そして、図２の状態から、底壁形成壁15の後部を押し上げると、反転壁13が上方に反転し、図１に示す如く、反転壁13の外周面が胴部10内周下端部に略接触する状態に反転する。その際、底壁形成壁15は前端部を中心に上方へ回動して上げ底状の底壁14を形成する。尚、底壁形成壁15と胴部10の下端開口とでは、底壁形成壁15の方が若干大きくなるが、底壁形成壁15を強制的に押し上げることで、底壁形成壁15を反転位置に押し上げることができる。合成樹脂により形成された容器体Ａは弾力性を備えているため、この様な操作が容易に行える。   Then, when the rear part of the bottom wall forming wall 15 is pushed up from the state of FIG. 2, the inversion wall 13 is inverted upward, and the outer peripheral surface of the inversion wall 13 is substantially at the lower end of the inner periphery of the body 10 as shown in FIG. Invert to touch. At that time, the bottom wall forming wall 15 is turned upward around the front end portion to form a bottom-like bottom wall 14. Note that the bottom wall forming wall 15 is slightly larger at the bottom wall forming wall 15 and the lower end opening of the body portion 10, but the bottom wall forming wall 15 is inverted by forcibly pushing up the bottom wall forming wall 15. Can be pushed up into position. Since the container A formed of a synthetic resin has elasticity, such an operation can be easily performed.

ポンプＢは、外周上部にフランジ20を延設し、フランジ20の下面周縁部より環状のシール筒21を垂設したシリンダ22を備え、フランジ20の外周縁部に装着筒23を嵌着固定している。装着筒23は上端より内方へ延設したフランジ状頂板24を、フランジ20と係合手段を持って不動に嵌着固定している。また、シリンダ22内より上方付勢状態で押し込み可能に突出したステムの上端に吐出ヘッド25を嵌着している。更に、シリンダ22の下端部に上端を嵌着した吸上げパイプ26を垂設している。吸上げパイプ26は中間部で屈曲する如く、屈曲形成されている。尚、フランジ状頂板24と、フランジ20との係合手段は、図３に拡大図で示す如く、フランジ20の上面周縁部に周方向多数の放射突条27突設し、一方フランジ状頂板24の下面に外周縁部に周方向多数の放射凹溝28を凹設し、両者を嵌合させて、相互の回動が不能に嵌着固定している。但し、これに代えてシリンダ22と装着筒23とを一体に形成しても良い。   The pump B is provided with a cylinder 22 having a flange 20 extending on the outer peripheral upper portion and an annular seal cylinder 21 suspended from the peripheral edge of the lower surface of the flange 20, and a mounting cylinder 23 is fitted and fixed to the outer peripheral edge of the flange 20. ing. The mounting cylinder 23 has a flange-like top plate 24 extending inwardly from the upper end and is fixedly fitted and fixed with the flange 20 and engaging means. Further, the discharge head 25 is fitted to the upper end of the stem that protrudes from the inside of the cylinder 22 so as to be pushed in an upward biased state. Further, a suction pipe 26 having an upper end fitted to the lower end portion of the cylinder 22 is suspended. The suction pipe 26 is bent so as to be bent at the intermediate portion. As shown in the enlarged view of FIG. 3, the flange-shaped top plate 24 and the flange 20 are engaged with a large number of radial projections 27 on the peripheral edge of the upper surface of the flange 20. A large number of radial grooves 28 are provided in the outer peripheral edge of the lower peripheral surface of the outer peripheral surface of the outer peripheral surface of the outer peripheral surface, and both are fitted to each other so as to be fitted and fixed so that mutual rotation is impossible. However, instead of this, the cylinder 22 and the mounting cylinder 23 may be integrally formed.

また、装着筒23の口頸部12への螺着時に、屈曲した吸上げパイプ26の下端開口を底壁14の最下方位置に開口するための位置決め手段を、口頸部12と装着筒23との間に設けている。位置決め手段は、口頸部12の外周下端部に周方向等間隔に多数突設した縦突条16の一部と、装着筒23の内周下端部の対向位置に一対突設した係合突条29で構成している。尚、位置決め手段を構成する縦突条16は上記多数のものの一部であり、縦突条16は上記の如く周方向多数突設する必要はなく、係合突条29の数に併せて必要な数だけ突出しても良い。   Further, positioning means for opening the lower end opening of the bent suction pipe 26 at the lowest position of the bottom wall 14 when the mounting cylinder 23 is screwed to the mouth neck 12 is provided with the mouth neck 12 and the mounting cylinder 23. Between. The positioning means includes a pair of engaging protrusions that protrude from a part of the vertical protrusion 16 that protrudes from the lower end of the outer periphery of the neck 12 at regular intervals in the circumferential direction and a position that opposes the lower end of the inner periphery of the mounting cylinder 23. Consists of Article 29. Incidentally, the vertical ridges 16 constituting the positioning means are a part of the above-mentioned many, and the vertical ridges 16 do not need to be provided in a large number in the circumferential direction as described above, and are necessary in accordance with the number of the engaging ridges 29. You can project as many as you like.

ポンプＢを容器体Ａに装着する際は、シリンダ22及び吸上げパイプ26を容器体Ａ内に垂下しつつ、容器体口頸部12外周に装着筒23を螺着させ、シール筒21を口頸部12内周に密嵌させる。シール筒21によりこの部分の液密性を図っている。また、その際、装着筒23の螺着終点時に装着筒23内面の係合突条29が、口頸部12外周の所定の縦突条16間に係合し、その時点で図１に示す如く吸上げパイプ26の先端が底壁14の最下方位置に開口している。尚、図１は吐出ヘッド25を押し下げた状態でシリンダ22の上端部に螺着した状態を示す。   When the pump B is mounted on the container body A, the cylinder 22 and the suction pipe 26 are suspended in the container body A, the mounting cylinder 23 is screwed onto the outer periphery of the container body neck 12 and the seal cylinder 21 is opened. The neck 12 is tightly fitted. The seal cylinder 21 ensures liquid tightness in this part. At that time, the engagement protrusion 29 on the inner surface of the mounting cylinder 23 is engaged between the predetermined vertical protrusions 16 on the outer periphery of the mouth-and-neck portion 12 at the end of screwing of the mounting cylinder 23, and at that time, as shown in FIG. Thus, the tip of the suction pipe 26 opens at the lowest position of the bottom wall 14. FIG. 1 shows a state in which the discharge head 25 is screwed to the upper end portion of the cylinder 22 while being pushed down.

上記の如く構成したポンプ容器は、図１の状態から、吐出ヘッド25をシリンダ22から螺脱して上昇させ、その状態から吐出ヘッド25を上下動させることで、内臓ポンプ機構の作用で吸上げパイプ26の下端開口より容器体Ａ内液を吸上げ吐出ヘッド25の吐出口30より吐出する。   In the pump container configured as described above, the discharge head 25 is unscrewed from the cylinder 22 and lifted from the state shown in FIG. 1, and the discharge head 25 is moved up and down from that state. The liquid in the container body A is sucked from the lower end opening of 26 and discharged from the discharge port 30 of the discharge head 25.
