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 costs, and in this case, the above-described central portion of the bottom 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、有底筒状の胴部より肩部を介して口頸部を起立した形態であり、胴部を円筒状或いは楕円筒状に形成したものである。   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 / neck part is erected from the bottomed cylindrical body part via the shoulder part, and the body part is formed in a cylindrical shape or an elliptical cylindrical shape.

また、本発明の容器体に適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適用可能である。   In addition, as a pump applicable to the container body of the present invention, the suction pipe is suspended in the container body and 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, the case where the liquid in the container is directly discharged from the discharge port as a liquid can be applied even if the liquid is discharged from the discharge port as bubbles by a known mechanism.

本発明の容器体は胴部内の下部に、胴部を一周する環状で、下向きの圧接用壁面を備えている。また、胴部の下端縁より下方へ延設した反転壁の下端縁より底壁形成壁を延設した形態で当初製造される。そして、反転壁を上方へ反転させて、底壁形成壁と反転壁が形成するコーナー部分、或いは反転壁を圧接用壁面に圧接させるとともに、底壁形成壁が上昇して上げ底状の底壁を形成する。従って、底壁となる底壁形成壁はそのままの状態で上方に移行し、また、底壁は少なくとも周縁部が内方へ下るテ−パ状に形成しているため、液が少なくなると中央部にたまる仕掛けとなっている。従って、吸い上げパイプの下端を底壁中央部に開口すれば残液なく収容液を吸い上げることができる。   The container body of the present invention is provided with a downward pressure-contacting wall surface in an annular shape that goes around the body part at the lower part in the body part. Further, it is initially manufactured in a form in which a bottom wall forming wall is extended from the lower end edge of the reversing wall extending downward from the lower end edge of the body portion. Then, the inversion wall is inverted upward, the corner portion formed by the bottom wall forming wall and the inversion wall, or the inversion wall is pressed against the pressure welding wall surface, and the bottom wall forming wall is raised to raise the bottom-shaped bottom wall. Form. Accordingly, the bottom wall forming wall that becomes the bottom wall moves upward as it is, and the bottom wall is formed in a taper shape in which at least the peripheral edge is lowered inward. It is a mechanism to accumulate. Therefore, if the lower end of the suction pipe is opened at the center of the bottom wall, the stored liquid can be sucked up without remaining liquid.

圧接用壁面は、胴部の壁部の一部を利用して形成したもので、ここに、反転壁と底壁形成壁とのコーナー部分或いは反転壁が圧接して、反転壁を上方へ反転させることで形成される上げ底状の底壁の周縁部を密閉する役割を果たす。その形状は、上記機能が可能であれば種々採用可能であるが、例えば下向きの水平面であっても、或いは傾斜面であっても良い。   The wall surface for pressure welding is formed by utilizing a part of the wall portion of the body portion, where the corner portion or the reversal wall between the reversal wall and the bottom wall forming wall is in pressure contact, and the reversal wall is reversed upward. It plays the role which seals the peripheral part of the raised bottom-shaped bottom wall formed by making it. The shape can be variously adopted as long as the above function is possible. For example, the shape may be a downward horizontal surface or an inclined surface.

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、それに加えて、反転壁と底壁形成壁とが形成するコーナー部分を弯曲面に形成することで反転を容易ならしめる如く構成しても良い。   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 to this, a corner portion formed by the reversal wall and the bottom wall forming wall may be formed as a curved surface so as to facilitate reversal.

反転壁の反転後に底壁となる底壁形成壁は、反転壁の反転時にかかる力により変形されない程度の厚みで形成すると良く、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あり、要件を満たせば前段落で記載した如き反転壁の厚さを採用する必要もない。   The bottom wall forming wall, which becomes the bottom wall after the reversal of the reversal wall, should be formed with a thickness that is not deformed by the force applied when the reversal wall is reversed, and the thickness of the reversal wall and the bottom wall forming wall is If they are selected as appropriate while exhibiting the above functions, it is possible to use either the same thickness or the same thickness. If the requirements are satisfied, it is not necessary to employ the thickness of the inversion wall as described in the previous paragraph.

また、反転壁の上端縁の胴部との境界に薄肉のヒンジを形成しても良い。   Moreover, you may form a thin hinge in the boundary with the trunk | drum of the upper end edge of an inversion wall.

A container body for a pump that discharges from an outlet 25. The body portion 10 has a cylindrical or elliptical cylindrical shape, and a downward annular pressure contact that is a lower surface of a recessed wall portion 17 that is recessed inwardly at the lower portion of the body portion 10. A wall surface f is provided, and a reversal wall 13 having the same cylindrical shape as that of the lower end portion of the body portion 10 is provided below the lower end edge of the body portion 10 so as to form a taper shape in which at least the peripheral portion is lowered inward. The bottom wall forming wall 15 is extended from the lower end edge of the reversing wall 13, and the reversing wall 13 is formed so as to be capable of reversing upward with the lower end edge of the body 10 as the center. Inverted upward, the corner portion 16 formed by the bottom wall forming wall 15 and the reversing wall 13 was pressed against the pressure wall surface f, and the bottom wall forming wall 15 was raised to form a bottom-like bottom wall 14. A container for a pump characterized by that.

第３の手段として、以下の通り構成した。即ち、前記第２の手段に於いて、反転壁13と底壁形成壁15とが形成するコーナー部分16を弯曲面に形成してなる。 The third means was configured as follows. That is, at the second hand stage, by forming a corner portion 16 of the inverted wall 13 and the bottom wall forming wall 15 is formed on the curved surface.

第４の手段として、以下の通り構成した。即ち、前記第１の手段乃至第３の手段のいずれかの手段に於いて、胴部10及び底壁形成壁15と比較して反転壁13を薄肉に形成した。 The fourth means is configured as follows. That is, in any one of the first to third means, the reversal wall 13 is formed thinner than the body 10 and the bottom wall forming wall 15.

本発明によれば、少なくとも周縁部が内方へ下るテ−パ状をなす底壁形成壁15を反転壁13の下端縁より延設し、反転壁13を上方へ反転させて、底壁形成壁15と反転壁13とが形成するコーナー部分16或いは反転壁13を、胴部10内の下部に形成した圧接用壁面ｆに圧接し、底壁形成壁15が上昇して上げ底状の底壁14を形成しているので、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。また、底壁14周縁部の密閉性を充分図ることができる。   According to the present invention, the bottom wall forming wall 15 having a taper shape with at least the peripheral edge falling inwardly extends from the lower end edge of the inversion wall 13, and the inversion wall 13 is inverted upward to form the bottom wall. The corner portion 16 or the reversal wall 13 formed by the wall 15 and the reversal wall 13 is brought into pressure contact with the pressure welding wall surface f formed at the lower part in the body portion 10, and the bottom wall formation wall 15 rises to raise the bottom. 14 is formed so that residual liquid can be prevented from being generated on the bottom wall 14 as much as possible, and even if it is molded by blow molding or the like, the bottom center has to be raised for structural reasons. Since it can be avoided, molding by blow molding or the like is possible, productivity is high, and manufacturing at low cost is possible. In addition, it is possible to sufficiently seal the peripheral edge of the bottom wall 14.

圧接用壁面ｆが、胴部10下部において、外方へ傾斜下降してその下方の胴部10を大径部10b として拡径する環状傾斜壁10a の下面であり、上記反転壁13が、胴部10の下端縁より下方へ垂設した胴部10の下端部と同形筒状をなし、反転壁13を上方へ反転させて底壁形成壁15と反転壁13とが形成するコーナー部分16を圧接用壁面ｆに圧接してなる場合には、圧接用壁面ｆが上下方向に幅を持つため、例え反転壁13等の寸法誤差，成形誤差等があっても、コーナー部分16と圧接用壁面ｆとの圧接がより確実に行える如く対応できる。また、下部が大径の胴部10を備えるため、容器体Ａの載置安定性をより増加する。   The pressure contact wall surface f is a lower surface of the annular inclined wall 10a that is inclined downward and expands at the lower portion of the body portion 10 so that the lower body portion 10 is enlarged as a large diameter portion 10b. The bottom part of the body part 10 suspended downward from the lower edge of the part 10 has the same cylindrical shape, and the corner part 16 formed by the bottom wall forming wall 15 and the inversion wall 13 is formed by inverting the inversion wall 13 upward. When pressed against the wall surface f for pressure contact, since the wall surface f for pressure contact has a width in the vertical direction, even if there are dimensional errors, molding errors, etc., such as the reversal wall 13, the corner portion 16 and the wall surface for pressure contact It is possible to cope with pressure contact with f more reliably. Moreover, since the lower part is provided with the trunk | drum 10 with a large diameter, the mounting stability of the container body A is increased more.

圧接用壁面ｆが、胴部10の下部に設けた内方へ凹む凹陥壁部17の下面であり、上記反転壁13が、胴部10の下端縁より下方へ垂設した胴部10の下端部と同形筒状をなし、反転壁13を上方へ反転させて底壁形成壁15と反転壁13とが形成するコーナー部分16を圧接用壁面ｆに圧接してなる場合には、胴部10の上端から下端まで突出部分がなく形成できる利点がある。   The pressure contact wall surface f is a lower surface of an inwardly recessed wall portion 17 provided in the lower portion of the body portion 10, and the inversion wall 13 is provided at the lower end of the body portion 10 that hangs downward from the lower end edge of the body portion 10. When the corner portion 16 formed by the bottom wall forming wall 15 and the reversing wall 13 is pressed against the pressure wall surface f by reversing the reversing wall 13 upward, There is an advantage that it can be formed without protruding portions from the upper end to the lower end of the.

反転壁13と底壁形成壁15とが形成するコーナー部分16を弯曲面に形成してなる場合には、圧接用壁面ｆとコーナー部分16との密閉性をより向上する。その結果、反転壁13と対向する胴部10との隙間に液が浸入する等の不都合をより確実に防止できる。   In the case where the corner portion 16 formed by the reversal wall 13 and the bottom wall forming wall 15 is formed as a curved surface, the sealing property between the press-fitting wall surface f and the corner portion 16 is further improved. As a result, it is possible to more reliably prevent inconveniences such as liquid intrusion into the gap between the reversing wall 13 and the body portion 10 facing the reversing wall 13.

胴部10及び底壁形成壁15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の反転が容易であり、底壁形成壁15が反転の際に変形する等の不都合を防止できる。   When the reversal wall 13 is formed thinner than the body 10 and the bottom wall forming wall 15, the reversal wall 13 can be easily reversed, and the bottom wall forming wall 15 is deformed when reversed. Can be prevented.

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上端より肩部11を介して口頸部12を起立している。胴部10は、下部に設けた外方へ傾斜下降する環状傾斜壁10a を介して、その下方を大径部10b とし、その上方を小径部10c として構成し、環状傾斜壁10a の下面を圧接用壁面ｆとして構成している。また、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。   FIG. 1 shows 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 is shouldered from the upper end of the cylindrical body 10. The mouth and neck 12 is erected through the part 11. The body portion 10 is configured such that the lower portion is formed as a large diameter portion 10b and the upper portion is formed as a small diameter portion 10c via an annular inclined wall 10a provided at the lower portion and inclined downward. It is configured as a wall surface f for use. In addition, a bottom wall 14 extends from the lower end portion of the trunk portion 10 via an 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、即ち大径部10b の下端縁より下方へ反転壁13を一体に垂設し、反転壁13の下端縁より反転壁13の下端開口を閉塞する底壁形成壁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 has a reversal wall 13 integrally suspended from the lower end edge of the body portion 10, that is, the lower end edge of the large diameter portion 10 b, and the reversal wall 13 from the lower end edge of the reversal wall 13. A bottom wall forming wall 15 is integrally extended to close the lower end opening.

反転壁13は、図２に示す如く、胴部10と同形筒状の、即ち円筒状をなし、外周面が胴部10下端部内周面、即ち、大径部10b の内周面と略同径程度に形成されている。また、反転壁13と底壁形成壁15とを結ぶコーナー部分16は弯曲面に形成し、即ちＲを設けている。更に、反転壁13及びコーナー部分16は、底壁形成壁15及び胴部10と比較して薄肉に形成しており、反転壁13の上方への容易な反転が可能に構成するとともに、反転壁13を反転させた際に、図１に示す如く、コーナー部分16も上方へ反転して上方へ斜め外方へ突出する弯曲面を形成する如く構成している。   As shown in FIG. 2, the inversion wall 13 has a cylindrical shape that is the same as that of the body portion 10, that is, a cylindrical shape, and the outer peripheral surface is substantially the same as the inner peripheral surface of the lower end portion of the body portion 10, that is, the inner peripheral surface of the large diameter portion 10b. It is formed about the diameter. Further, the corner portion 16 connecting the reversing wall 13 and the bottom wall forming wall 15 is formed as a curved surface, that is, R is provided. Further, the reversal wall 13 and the corner portion 16 are formed thinner than the bottom wall forming wall 15 and the body portion 10, and are configured so that the reversal wall 13 can be easily reversed upward. When 13 is inverted, as shown in FIG. 1, the corner portion 16 is also inverted so as to form a saddle curved surface protruding upward and obliquely outward.

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ている。中央に周縁部と相似形態の円形状をなす陥没した平坦壁部15a を備え、平坦壁部15a の周囲を内方へ下るテーパー壁部15b に形成している。この底壁形成壁15は反転壁13が反転した際に上昇して同様の平坦壁部14a 及びテーパー壁部14b を備えた底壁14となる。   The bottom wall forming wall 15 extends integrally by closing the lower end opening of the inversion wall 13 from the lower end edge of the inversion wall 13. A flat wall portion 15a having a depressed shape having a circular shape similar to that of the peripheral edge portion is provided at the center, and a tapered wall portion 15b is formed inwardly around the flat wall portion 15a. The bottom wall forming wall 15 rises when the reversal wall 13 is reversed, and becomes a bottom wall 14 having the same flat wall portion 14a and tapered wall portion 14b.

そして、図２の状態から、底壁形成壁15を胴部10に対して上方に押し上げると、反転壁13が上方に反転し、図１に示す如く、反転壁13と底壁14とを結ぶコーナー部分16が圧接用壁面ｆに圧接する。その際、底壁形成壁15はそのままの状態で上昇して上げ底状の底壁14を形成する。   Then, when the bottom wall forming wall 15 is pushed upward with respect to the body portion 10 from the state of FIG. 2, the inversion wall 13 is inverted upward, and the inversion wall 13 and the bottom wall 14 are connected as shown in FIG. The corner portion 16 is in pressure contact with the pressure wall surface f. At that time, the bottom wall forming wall 15 is lifted as it is to form a bottom-like bottom wall 14.

ポンプＢは、容器体口頸部12外周に嵌合させた装着筒20により容器体Ａに固定されたもので、パッキンｐを介して口頸部12上に装着したシリンダ21のフランジを、装着筒20のフランジ状頂板により固定し、シリンダ21の下部を容器体Ａ内上部に垂下させ、また、シリンダ21より上方付勢状態で押し込み可能に突設したステム（図示せず）の上端に吐出ヘッド23を嵌着している。また、シリンダ21の下端部に上端を嵌着した吸上げパイプ24の下端を平坦壁部14a 上面近傍に垂設開口している。尚、図１は吐出ヘッド23を押し下げた状態でシリンダ21の上端部に螺着した状態を示す。   The pump B is fixed to the container body A by a mounting cylinder 20 fitted to the outer periphery of the container body neck portion 12 and is mounted with a flange of the cylinder 21 mounted on the neck portion 12 via a packing p. It is fixed by the flange-like top plate of the cylinder 20, the lower part of the cylinder 21 is suspended from the upper part in the container body A, and discharged to the upper end of a stem (not shown) protruding so as to be able to be pushed upward from the cylinder 21. The head 23 is fitted. Further, the lower end of the suction pipe 24 whose upper end is fitted to the lower end portion of the cylinder 21 is vertically opened near the upper surface of the flat wall portion 14a. FIG. 1 shows a state in which the discharge head 23 is screwed onto the upper end portion of the cylinder 21 while being pushed down.

上記の如く構成したポンプ容器１は、図１の状態から吐出ヘッド23をシリンダ21から螺脱して上昇させ、その状態から吐出ヘッド23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24の下端開口より容器体Ａ内液を吸上げ吐出ヘッド23の吐出口25より吐出する。   In the pump container 1 configured as described above, the discharge head 23 is unscrewed from the cylinder 21 and lifted from the state shown in FIG. 1, and the discharge head 23 is moved up and down from this state. The liquid in the container body A is sucked up from the lower end opening of 24 and discharged from the discharge port 25 of the discharge head 23.

図３は他の例を示すもので、環状傾斜壁10a を、胴部10の下部に設けた内方へ凹む凹陥壁部17の下半部で構成した例を示す。凹陥壁部17は胴部10の下部所定位置を半円状に内方に陥没させたもので、この凹陥壁部17の下面を圧接用壁面ｆとして構成している。従って、胴部10は凹陥壁部17の部分以外は同径をなす。その他の構成は図１の例と同様であるため、同符号を付して説明を省略する。   FIG. 3 shows another example, and shows an example in which the annular inclined wall 10a is constituted by the lower half portion of the recessed wall portion 17 recessed inwardly provided in the lower portion of the body portion 10. The recessed wall portion 17 is formed by recessing a predetermined position of the lower portion of the body portion 10 inwardly in a semicircular shape, and the lower surface of the recessed wall portion 17 is configured as a pressing wall surface f. Therefore, the trunk portion 10 has the same diameter except for the concave wall portion 17. The other configuration is the same as that of the example of FIG.

この場合も容器体Ａの底部は、当初図３の二点鎖線で示す如く、反転壁13及び底壁形成壁15が下方へ突出した状態で形成され、その状態から底壁形成壁15を胴部10に対して上方に押し上げると、反転壁13が上方に反転し、反転壁13と底壁14とを結ぶコーナー部分16が圧接用壁面ｆに圧接する。その際、底壁形成壁15はそのままの状態で上昇して上げ底状の底壁14を形成する。   Also in this case, the bottom of the container A is initially formed with the inversion wall 13 and the bottom wall forming wall 15 protruding downward, as shown by the two-dot chain line in FIG. When pushed up with respect to the portion 10, the reversal wall 13 is reversed upward, and the corner portion 16 connecting the reversal wall 13 and the bottom wall 14 is in pressure contact with the pressure contact wall surface f. At that time, the bottom wall forming wall 15 is lifted as it is to form a bottom-like bottom wall 14.

図４は更に他の例を示すもので、本例では胴部10下端部を外方へ傾斜下降するスカート壁10d に形成し、このスカート壁10d の下面を圧接用壁面ｆとして構成している。また、図４の二点鎖線で示す如く、スカート壁10d の下端縁より下方へスカート壁10d と対称的に内方へ傾斜下降する逆スカート状をなす反転壁13を延設し、反転壁13の下端縁からは図１と同様の底壁形成壁15を延設している。従って、胴部10はスカート壁10d の部分以外は同径をなす。その他の構成は図１の例と同様であるため、同符号を付して説明を省略する。   FIG. 4 shows still another example. In this example, the lower end portion of the body portion 10 is formed on the skirt wall 10d inclined downward, and the lower surface of the skirt wall 10d is configured as a pressure welding wall surface f. . Further, as shown by a two-dot chain line in FIG. 4, a reverse wall 13 having an inverted skirt shape extending downwardly from the lower end edge of the skirt wall 10d symmetrically inwardly with the skirt wall 10d extends. A bottom wall forming wall 15 similar to that shown in FIG. Therefore, the trunk portion 10 has the same diameter except for the portion of the skirt wall 10d. The other configuration is the same as that of the example of FIG.

この場合も容器体Ａの底部は、当初図４の二点鎖線で示す如く、反転壁13及び底壁形成壁15が下方へ突出した状態で形成され、その状態から底壁形成壁15を胴部10に対して上方に押し上げると、反転壁13が上方に反転し、反転壁13外面が圧接用壁面ｆに圧接する。その際、底壁形成壁15はそのままの状態で上昇して上げ底状の底壁14を形成する。   Also in this case, the bottom of the container A is initially formed with the inversion wall 13 and the bottom wall forming wall 15 protruding downward, as shown by the two-dot chain line in FIG. When pushed upward with respect to the portion 10, the reversal wall 13 is reversed upward, and the outer surface of the reversal wall 13 is in pressure contact with the pressure wall surface f. At that time, the bottom wall forming wall 15 is lifted as it is to form a bottom-like bottom wall 14.

図５は更に他の例を示すもので、円筒状の胴部10の下端縁より下方へ胴部10と同形筒状の反転壁13を延設し、反転壁13の下端縁より図１と同様の底壁形成壁15を延設している。反転壁13は、胴部10及び底壁形成壁15の厚さより薄肉に形成されており、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ている。また、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が上昇して上げ底状の底壁14を形成している。また、本例では反転後の反転壁13と胴部10下端部とを溶着固定している。その溶着固定手段としては、例えば、高周波接着等の公知手段を採用できる。その他の構成は図１の例と同様であるため、同符号を付して説明を省略する。   FIG. 5 shows still another example, in which a cylindrical reversing wall 13 having the same shape as that of the body 10 extends downward from the lower end edge of the cylindrical body 10, and FIG. A similar bottom wall forming wall 15 is extended. The inversion wall 13 is formed to be thinner than the thickness of the body portion 10 and the bottom wall forming wall 15, and the inversion wall 13 is formed so as to be able to invert upward about the lower end edge of the body portion 10. Further, the inversion wall 13 is inverted upward to bring the outer peripheral surface into contact with the lower end portion of the inner peripheral surface of the body portion 10, and the bottom wall forming wall 15 is raised to form a bottom-like bottom wall 14. . In this example, the inverted wall 13 after inversion and the lower end portion of the body portion 10 are welded and fixed. As the welding and fixing means, for example, known means such as high frequency bonding can be adopted. The other configuration is the same as that of the example of FIG.

この場合も容器体Ａの底部は、当初図５の二点鎖線で示す如く、反転壁13及び底壁形成壁15が下方へ突出した状態で形成され、その状態から底壁形成壁15を胴部10に対して上方に押し上げると、反転壁13外面と胴部10内周面とが当接する状態に反転壁13が反転する。その際、底壁形成壁15はそのままの状態で上昇して上げ底状の底壁14を形成する。その後、後加工で反転壁13と胴部10の下端部とを溶着固定する。尚、この後加工での溶着固定をしない状態も、本発明の一つの形態を示す。   Also in this case, the bottom of the container body A is initially formed with the inversion wall 13 and the bottom wall forming wall 15 protruding downward, as shown by the two-dot chain line in FIG. When pushed up with respect to the portion 10, the reversing wall 13 is reversed so that the outer surface of the reversing wall 13 and the inner peripheral surface of the body portion 10 are in contact with each other. At that time, the bottom wall forming wall 15 is lifted as it is to form a bottom-like bottom wall 14. Thereafter, the reverse wall 13 and the lower end portion of the body portion 10 are welded and fixed by post-processing. In addition, the state which does not carry out the welding fixation by this post-processing also shows one form of this invention.
