【０００１】
【発明の属する技術分野】
本発明は、ほぼ一定量の液体を容器体内から取出し、他の容器等に移すことが可能に設けた液体分配容器に関する。
【０００２】
【従来の技術】
この種の従来の容器は、例えば実開平７‐８５９号のように、弾性圧搾可能な胴部を有する容器体口頸部へ嵌合させたキャップ状部材の頂壁中央部に押上げパイプ付きの口筒を貫設しておき、又頂壁よりも上方へ突出する口筒部分の外面へ水密に着脱できる筒部を底壁中央部に貫設した計量カップを設け、その筒部を上記口筒へ嵌合させて、該計量カップを上記キャップ状部材上へ載置させ、該状態から容器体胴部を圧搾することで計量カップ内に容器体内液体を入れ、次いで計量カップを外して該カップ内液体を他の容器等に移すものである。
【０００３】
【発明が解決しようとする課題】
上記従来の液体分配容器では、計量カップ内での液体計量を、容器体胴部圧搾によって計量カップ内で上昇する液面を目視し乍ら行うこととなり、目視しないで容器体胴部の圧搾を継続すると、計量カップから溢水することとなる。
【０００４】
請求項１記載の発明は上記計量カップに代えて、上端面開口のシリンダを、従来のキャップ状部材に代る保持筒部材内へ嵌合させると共に、該シリンダ内へプランジヤを嵌合させておき、容器体胴部の圧搾によって容器体内液体がシリンダ内へ入るとプランジヤが押上げられ、該プランジヤが上限まで押上げられたときに生ずる胴部圧搾の手應えでシリンダ内に液体が充満したことを知ることが出来るよう設けたものである。
【０００５】
請求項２記載の発明は、上記請求項１記載発明が有する課題のほか、シリンダ内へ入った液体が再び容器体内へ還流しないよう、又液体減少により負圧化した容器体内へ外気が流入してその負圧化状態を解消できるよう設けたものである。
【０００６】
請求項３記載の場合は、上記請求項１又は２記載の課題のほか、シリンダを保持筒部材に螺合させることでプランジヤが上限まで押上げられた後は、容器体胴部の圧搾が不能となるよう設けたものである。
【０００７】
請求項４記載の場合も、請求項１又は２記載の課題のほか、シリンダと保持筒部材とが假位置決めされてプランジヤがシリンダ上限まで押上げられると容器体胴部の圧搾が困難となると共に、シリンダ抜き出しに際しては、該シリンダを保持筒部材に対して回動させることで該シリンダが一定高さ上昇して、該シリンダ抜出しが容易であるよう設けたものである。
【０００８】
【課題を解決するための手段】

上記口頸部上端面へ係合させた鍔状頂壁13から装着筒12を垂下して口頸部４外面へ嵌合させると共に、上記鍔状頂壁13からガイド筒14を、かつ該ガイド筒下端から縮径部15を介して容器体内へ押上げパイプ16付きの口筒17を、それぞれ装着筒12と同軸に突設する保持筒部材11と、
上記ガイド筒14内へ嵌合させたシリンダ26下端から、内向きフランジ27を介して小内径のノズル28を垂下し、該ノズル下端を上記口筒17の上端部内へ水密に嵌合させ、又シリンダ26上端に、上記保持筒部材11からの引抜き用把手30を付設したシリンダ付き部材25と、上記シリンダ内へ、水密にかつ上下動自在に嵌合させたプランジヤ35と、
上記シリンダの上端部内面へ固着されて、プランジヤ35の抜出しを防止するストッパ42とからなり、
上記容器体胴部の強制圧搾によって、押上げパイプ16、口筒17、ノズル28を通ってシリンダ内へ入った液体が、プランジヤ35を押上げ可能に形成し、
又上記縮径部15の上端部分から、複数かつ同一大きさの山形突部46を等間隔に起立すると共に、それ等山形突部の各上面に下面を噛合う複数の逆山形突部47をシリンダ下端の内向きフランジ27外周部から垂設し、
又ガイド筒14とシリンダ26との各上部対向面に、互いに係合してガイド筒14に対してシリンダ26を下限位置で假止めする凹凸の係合手段45を付設した。
【００１７】
【発明の実施の形態】
まず、図１から図３が示す実施形態について説明すると、１は弾性圧搾可能に設けた胴部２を有する容器体で、胴部上端から肩部３を介して口頸部４を起立する。
【００１８】
上記容器体の口頸部４外面へは、保持筒部材１１の装着筒１２を螺合させている。該保持筒部材は、装着筒上端に付設した鍔状頂壁１３内周縁からガイド筒１４を容器体内へ垂下し、該ガイド筒下端から縮径部１５を介して押上げパイプ１６付きの口筒１７を垂下する。上記ガイド筒１４、口筒１７は装着筒１２と同軸とする。
【００１９】
上記縮径部１５は、図示例においてガイド筒１４下端から小内径の雌ねじの螺筒１５ａを段部を介して垂設すると共に、該螺筒下端に付設した内向きフランジ１５ｂ内縁で小径筒１５ｃの中間部を保持し、更に該小径筒下端内面に付設した内向きフランジ状突部内縁を口筒１７の上部外面へ連結して該口筒を保持している。小径筒下端には外気吸入用小透孔１８を穿設しており、又口筒１７の中間部内面には玉弁１９による吸込み弁２０を設け、口筒下半に押上げパイプ１６の上端部を嵌着させている。上記外気吸入用小透孔１８はガイド筒１４に穿設してもよい。
【００２０】
上記保持筒部材１１内へは、シリンダ付き部材２５を着脱自在にかつ好ましくは水密に嵌合させる。該部材は上記ガイド筒１４内へ嵌合させたシリンダ２６下端から、内向きフランジ２７を介して小内径のノズル２８を垂下し、該ノズル下端を上記口筒１７の上端部内へ水密に嵌合させ、又シリンダ上端から既述鍔状頂壁１３上面へ係合させた外向きフランジ２９を介して左右反対方向へ、保持筒部材１１内からの引抜き用把手３０を突設している。尚上記内向きフランジ２７の外周部からは雄ねじ筒３１を垂下し、該雄ねじ筒を既述螺筒１５ａ内面へ螺合させている。該雄ねじ筒内面は図１において小径筒１５ｃの上部外面へ水密に嵌合させている。
【００２１】
上記シリンダ２６内へは、水密にかつ上下動自在にプランジヤ３５を嵌合させている。該プランジヤは、筒状ピストン３６の中間部内面に付設した内向きフランジ状板３７内周縁から嵌合筒３８を起立する下部材３９と、上記嵌合筒３８外面へ下方筒部を嵌着させた有頂筒４０とで形成している。
【００２２】
既述シリンダ２６の上端部内面へは、プランジヤ３５の抜出し防止用の環状ストッパ４２を嵌着させている。該ストッパはプランジヤ３５がシリンダ内を上昇して筒状ピストン３６上端がストッパ４２下端に接することで上昇を阻止され、その抜出しが防止されるものである。
【００２３】
上記構成において、予め容器体内へ液体を入れておき、容器体胴部２を強制圧搾すると、容器体内高圧化で押上げパイプ１６、口筒１７、ノズル２８内を通って容器体内液体がシリンダ２６内へ入り、プランジヤ３５を押上げし、該プランジヤの筒状ピストン３６上端がストッパ４２に接することで図３のようにプランジヤ３５は停止する。該状態からシリンダ付き部材２５を螺脱して引抜き、かつプランジヤ３５をシリンダ２６に対して押下げることでシリンダ内液体を他の容器体内等へ移すことが出来る。
【００２４】
図４と図５が示す第２実施形態は、既述第１実施形態における螺筒１５ａと雄ねじ筒３１との螺合に代えてガイド筒１４とシリンダ２６とを直接各上部に設けた雌ねじ部１４ａと雄ねじ部２６ａとで螺合させている。又プランジヤ３５は、筒状ピストン３６の中間部内面に付設した内向きフランジ状板３７内周から直接に有頂の筒部を起立して形成している。上記内向きフランジ状板３７下面からは筒状ピストン保護のための短筒３７ａを垂下するとよい。
【００２５】
その他部分の構造は第１実施形態の場合とほぼ同様であり、その使用も同様に行えばよい。
【００２６】
図６と図７が示す第３実施形態の場合は、ガイド筒１４を鍔状頂壁１３から上方へ起立し、又鍔状頂壁１３内周から容器体口頸部４内面へ嵌合させて嵌合筒１５ｄを垂下し、該嵌合筒下端に付設した内向きフランジ１５ｅ内周を口筒１７の上部外面へ連結して該口筒を吊下げている。該実施形態にあっては、ガイド筒１４下端から内方の鍔状頂壁部分と、嵌合筒１５ｄと、内向きフランジ１５ｅとが縮径部１５を形成する。
【００２７】
シリンダ２６は上記ガイド筒１４内へ嵌合させればよく、ガイド筒１４とシリンダ２６とは各上部で図４の場合と同様雌ねじ部１４ａと雄ねじ部２６ａとで螺合させている。プランジヤ３５は底板付きの二重筒としており、その内外両筒間には複数のリブを介在させて内外両筒を連結している。又外筒の下部外面に筒状ピストン３６を付設している。
【００２８】
該実施形態は、シリンダ２６を容器体口頸部４よりも大内径に形成する場合に便利であり、鍔状頂壁１３下面から装着筒１２を垂下すると共に、該装着筒上端を接続する鍔状頂壁部分よりもやや外方頂壁部分から装着筒１２と同軸にガイド筒１４を起立し、口頸部４とほぼ同外径のシリンダ２６をそのガイド筒１４内へ嵌合させている。鍔状頂壁１３外周からは、斜下外方へのテーパ状部を介して、装着筒１２を囲成する化粧筒を垂下している。
その他部分の構造は、既述各実施形態と同様に設ければよい。
【００２９】
図８と図９とが示す第４実施形態は、既述図１から図３までの第１実施形態における螺筒１５ａと雄ねじ筒３１との螺合に代え、ガイド筒１４とシリンダ２６との各上部に凹凸の係合手段４５を設け、又ガイド筒１４の下端内面に外面側を付設させて、縮径部１５上端の外周部から、同一大きさに設けた複数の山形突部４６を等間隔に起立し、かつそれ等山形突部４６の各上面に下面を噛合う複数の逆山形突部４７をシリンダ２６下端の内向きフランジ２７外周部から垂下し、図示状態から把手３０を介してシリンダ付き部材２５を回すと、上記正逆の両山形突部の噛合せ面が噛合うことでガイド筒１４に対してシリンダ２６が押上げられ、すると上記係合手段４５が外れて、ガイド筒１４に対してシリンダ付き部材２５が上方へ引抜き可能としている。その他部分の構造は、図１の場合と同様である。
【００３０】
尚既述各実施形態にあっては口筒１７に吸込み弁２０を設け、又縮径部１５ないしガイド筒１４に外気吸込用小透孔１８を設けるが、これ等は必しも必要ではなく、これ等を設けない場合は、容器体胴部を圧搾してプランジヤ３５が上限に移動するまでシリンダ内へ液体を圧入させた後、その胴部圧縮状態を保ったままで胴部の加圧を停止し、該状態からシリンダ付き部材２５を抜出した後、上記圧縮状態を解放することで胴部を弾性復元させる。このようにすることでプランジヤを上昇させてシリンダ２６内へ所定量の液体を圧入させ、そのままシリンダ付き部材２５を抜出すことが出来る。抜出し後に胴部の圧搾を弛めれば外気流入により胴部は弾性復元する。
【００３１】
上記方法に対して吸込み弁２０および外気吸入用小透孔１８を穿設した場合は、容器体胴部圧搾によるシリンダ内への液体流入によってプランジヤ３５が上限まで上昇したとき胴部の圧搾を弛めても、吸込み弁２０が閉塞するためシリンダ２６内液体が容器体内に吸戻しされることはなく、よって胴部圧搾の手を弛めたままでシリンダ付き部材２５をガイド筒１４内から抜出すことが出来、又抜出し後に外気吸入用小透孔１８から外気が容器体内へ流入することで、容器体胴部は弾性復元する。
【００３２】
又保持筒部材１１とシリンダ付き部材２５との螺合又は係合手段４５による係合も必しも必要ではない。これ等を設けなければ、容器体胴部圧搾によりシリンダ内へ流入した液体がプランジヤ３５を上限まで押上げた後、続いてシリンダ２６が保持筒部材１１に対して押上げられる筈であるが、実際にはプランジヤ押上げよりもシリンダ押上げにより多くの力を要するからその胴部圧搾の手応えの変化によりプランジヤ３５が上限まで上昇したことを知ることが出来、このとき容器体胴部の圧搾を停止することが出来る。
【００３３】
既述液体分配容器の各構成部材は、玉弁１９を除き、すべて合成樹脂材で成形しているが、玉弁１９は金属、合成樹脂、その他玉弁に適する材料で成形すればよい。
【００３４】
【発明の効果】
請求項１記載の発明は、既述のように、容器体胴部の圧搾によりプランジヤ３５が押上げられてシリンダ２６内へ容器体内液体が流入し、プランジヤ３５が上限に達したことを手応えによって知ることが出来るよう設けたから、従来のように計量カップ内へ流入した液体量を常に目視する必要がなく、又計量後、つまりプランジヤ３５が上限に達した後は、シリンダ付き部材２５を保持筒部材１１内から抜出し、プランジヤ３５をシリンダ２６内へ押込むことでシリンダ内液体をノズル２８から注出できるから、液体の移し変えを容易に行うことが出来る。又ノズル２８は小内径としたから、シリンダ付き部材２５を保持筒部材１１内から抜出しただけでは、プランジヤ３５を押下げない限り、そのノズルから液洩れすることを防止することが出来る。
【００３５】
請求項２記載の場合は、上記請求項１発明の効果を有するほか、保持筒部材１１の口筒１７内に吸込み弁２０を設け、又縮径部１５ないしガイド筒１４に外気吸入用小透孔１８を穿設したから、容器体胴部の圧搾によってシリンダ２６内へ流入した液体がプランジヤ３５を上限まで押上げた後、胴部の圧搾を解放しても吸込み弁２０があるため、シリンダ内液体が容器体胴部内の負圧化で吸戻されることがなく、よってシリンダ付き部材抜取り操作を容易に行うことが出来る。
【００３６】
請求項３記載の場合は、既述請求項１又は２記載容器が有する効果のほか、保持筒部材１１が有する筒部分内面一部と、該筒部分内に嵌合するシリンダ付き部材２５が有する筒部分外面一部とを螺合させたから、プランジヤ３５がシリンダ２６の上限まで押上げられた後も既述手応えに気付かずに、更に容器体胴部を圧搾し続けた場合も、シリンダ付き部材２５が保持筒部材１１から抜出すおそれは全くない。
【００３７】
請求項４記載の場合は、請求項１又は２記載の容器が有する効果のほか、ガイド筒１４とシリンダ２６との各上部対向面に互いに係合してガイド筒１４に対してシリンダ２６を下限位置で假止めする凹凸の係合手段４５を付設したから、上記請求項３記載容器の場合と同様、プランジヤ３５が上限まで押上げられてシリンダ内に液体が充満したことの手応えがあった後、更に容器体胴部を圧搾し続けても、該圧搾によってはシリンダ付き部材２５が保持筒部材１１から抜出すことはなく、又縮径部１５上端外周部とシリンダ下端の内向きフランジ２７外周部とに、互いに噛合う複数の正逆の山形突部４６，４７を付設したから、保持筒部材１１に対してシリンダ付き部材２５を回動させると、シリンダ付き部材２５の逆山形突部４７が保持筒部材１１の山形突部４６上へ乗上げて、シリンダ付き部材が上昇することとなり、よって該シリンダ付き部材の抜出しを容易に行うことが出来る効果がある。

The stopper is prevented from rising by the plunger 35 rising in the cylinder and the upper end of the cylindrical piston 36 coming into contact with the lower end of the stopper 42, thereby preventing the stopper from being pulled out.
[0023]
In the above configuration, when the liquid is put in the container in advance and the container body 2 is forcibly squeezed, the liquid in the container passes through the push-up pipe 16, the mouth tube 17, and the nozzle 28 due to the high pressure in the container. When the plunger 35 is pushed in, the plunger 35 is pushed up, and the upper end of the tubular piston 36 of the plunger comes into contact with the stopper 42, the plunger 35 stops as shown in FIG. From this state, the cylinder-equipped member 25 is screwed out and pulled out, and the plunger 35 is pushed down against the cylinder 26, whereby the liquid in the cylinder can be transferred to another container body or the like.
[0024]
The second embodiment shown in FIGS. 4 and 5 is an internal thread portion in which a guide cylinder 14 and a cylinder 26 are provided directly on each upper portion instead of screwing the screw cylinder 15a and the male thread cylinder 31 in the first embodiment. 14a and male screw part 26a are screwed together. Further, the plunger 35 is formed by erecting a crested cylindrical portion directly from the inner periphery of an inwardly flanged plate 37 attached to the inner surface of the intermediate portion of the cylindrical piston 36. A short cylinder 37a for protecting the cylindrical piston may be suspended from the lower surface of the inward flange-shaped plate 37.
[0025]
The structure of other parts is almost the same as in the case of the first embodiment, and its use may be performed in the same manner.
[0026]
In the case of the third embodiment shown in FIGS. 6 and 7, the guide cylinder 14 is erected upward from the bowl-shaped top wall 13 and fitted from the inner periphery of the bowl-shaped top wall 13 to the inner surface of the container mouth / neck 4. The fitting cylinder 15d is suspended and the inner periphery of the inward flange 15e attached to the lower end of the fitting cylinder is connected to the upper outer surface of the mouth cylinder 17 to suspend the mouth cylinder. In the present embodiment, the flanged top wall portion inward from the lower end of the guide tube 14, the fitting tube 15 d, and the inward flange 15 e form the reduced diameter portion 15.
[0027]
The cylinder 26 may be fitted into the guide cylinder 14, and the guide cylinder 14 and the cylinder 26 are screwed at each upper portion by the female screw portion 14a and the male screw portion 26a as in the case of FIG. The plunger 35 is a double cylinder with a bottom plate, and a plurality of ribs are interposed between the inner and outer cylinders to connect the inner and outer cylinders. A cylindrical piston 36 is attached to the lower outer surface of the outer cylinder.
[0028]
This embodiment is convenient when the cylinder 26 is formed with a larger inner diameter than the container body neck 4, and the mounting cylinder 12 is suspended from the lower surface of the bowl-shaped top wall 13 and the upper end of the mounting cylinder is connected. The guide cylinder 14 is erected coaxially with the mounting cylinder 12 from the outer top wall part slightly from the shape top wall part, and the cylinder 26 having substantially the same outer diameter as the mouth neck 4 is fitted into the guide cylinder 14. . From the outer periphery of the bowl-shaped top wall 13, a decorative cylinder surrounding the mounting cylinder 12 is suspended via a tapered portion outwardly obliquely downward.
What is necessary is just to provide the structure of another part similarly to each above-mentioned embodiment.
[0029]
The fourth embodiment shown in FIGS. 8 and 9 replaces the screwing of the screw cylinder 15a and the male screw cylinder 31 in the first embodiment shown in FIGS. An uneven engaging means 45 is provided on each upper part, and an outer surface side is provided on the inner surface of the lower end of the guide tube 14, so that a plurality of mountain-shaped protrusions 46 having the same size are provided from the outer periphery of the upper end of the reduced diameter portion 15. A plurality of inverted chevron projections 47 that stand up at equal intervals and engage the lower surfaces of the upper surfaces of the chevron projections 46 hang down from the outer periphery of the inward flange 27 at the lower end of the cylinder 26. When the cylinder-attached member 25 is rotated, the cylinder 26 is pushed up with respect to the guide cylinder 14 by the meshing surfaces of the forward and reverse mountain-shaped protrusions engaging with each other. The cylinder member 25 can be pulled upward with respect to the cylinder 14. It is said. The structure of the other parts is the same as in FIG.
[0030]
In each of the embodiments described above, the suction valve 20 is provided in the mouth tube 17, and the small through hole 18 for sucking outside air is provided in the reduced diameter portion 15 or the guide tube 14, but this is not always necessary. If these are not provided, the container body is squeezed and liquid is pressed into the cylinder until the plunger 35 moves to the upper limit, and then the body is pressurized while maintaining its compressed state. After stopping and extracting the cylinder-equipped member 25 from this state, the body is elastically restored by releasing the compressed state. By doing so, the plunger can be raised to press-fit a predetermined amount of liquid into the cylinder 26, and the cylinder-equipped member 25 can be withdrawn as it is. If the squeezing of the body part is loosened after extraction, the body part will be elastically restored by the inflow of outside air.
[0031]
When the suction valve 20 and the small through hole 18 for sucking outside air are provided in the above method, when the plunger 35 is raised to the upper limit due to the liquid flowing into the cylinder by the container body squeezing, the squeezing of the body is relaxed. Even if the suction valve 20 is closed, the liquid in the cylinder 26 is not sucked back into the container body. Therefore, the cylinder-equipped member 25 is pulled out from the guide tube 14 with the hand of the body part compressed. In addition, the outside of the container body is elastically restored by the outside air flowing into the container body from the outside air suction small through hole 18 after the extraction.
[0032]
Further, the holding cylinder member 11 and the cylinder member 25 are not necessarily screwed or engaged by the engaging means 45. If these are not provided, the liquid that has flowed into the cylinder due to the container body squeezing pushes the plunger 35 up to the upper limit, and then the cylinder 26 is pushed up against the holding cylinder member 11. Actually, more force is required to push up the cylinder than to push up the plunger, so it is possible to know that the plunger 35 has risen to the upper limit due to the change in the response of the barrel squeezing. You can stop.
[0033]
The constituent members of the liquid distribution container described above are all made of a synthetic resin material except for the ball valve 19. However, the ball valve 19 may be made of metal, synthetic resin, or other material suitable for the ball valve.
[0034]
【The invention's effect】
As described above, according to the first aspect of the present invention, the plunger 35 is pushed up by the squeezing of the container body, and the liquid in the container flows into the cylinder 26, so that the plunger 35 reaches the upper limit. Since it is provided so that it can be known, it is not always necessary to visually observe the amount of liquid flowing into the measuring cup as in the prior art, and after measurement, that is, after the plunger 35 reaches the upper limit, the cylinder-equipped member 25 is held by the holding cylinder. By extracting from the member 11 and pushing the plunger 35 into the cylinder 26, the liquid in the cylinder can be poured out from the nozzle 28, so that the liquid can be easily transferred. Further, since the nozzle 28 has a small inner diameter, it is possible to prevent liquid leakage from the nozzle only by pulling out the cylinder-equipped member 25 from the holding cylinder member 11 unless the plunger 35 is pushed down.
[0035]
In the case of the second aspect, in addition to the effect of the first aspect of the invention, a suction valve 20 is provided in the mouth tube 17 of the holding cylinder member 11, and the small diameter portion 15 or the guide tube 14 has a small permeability for sucking outside air. Since the hole 18 is formed, the liquid that has flowed into the cylinder 26 due to the squeezing of the container body pushes the plunger 35 up to the upper limit, and the suction valve 20 is provided even if the squeezing of the trunk is released. The internal liquid is not sucked back by the negative pressure in the container body, so that the member with cylinder can be easily pulled out.
[0036]
In the case of claim 3, in addition to the effects of the container described in claim 1 or 2, the holding cylinder member 11 has a part of the inner surface of the cylinder part and the member with cylinder 25 fitted into the cylinder part. Since the cylinder part outer surface part is screwed together, even after the plunger 35 is pushed up to the upper limit of the cylinder 26, the container body part is also squeezed even if the container body part continues to be squeezed without noticing the aforementioned response. There is no possibility that 25 is pulled out from the holding cylinder member 11.
[0037]
In the case of claim 4, in addition to the effect of the container of claim 1 or 2, the upper surface of the guide cylinder 14 and the cylinder 26 are engaged with each other and the cylinder 26 is lower than the guide cylinder 14. Since the concave / convex engaging means 45 is provided to stop at the position, as in the case of the container according to claim 3, after the plunger 35 is pushed up to the upper limit and the liquid is filled in the cylinder, there is a response. Furthermore, even if the container body is continuously squeezed, the cylinder member 25 is not pulled out of the holding cylinder member 11 by the squeezing, and the outer periphery of the inward flange 27 at the upper end outer peripheral portion of the reduced diameter portion 15 and the lower end of the cylinder. Since a plurality of forward and reverse chevron protrusions 46, 47 meshing with each other are attached to the part, when the member 25 with cylinder is rotated with respect to the holding cylinder member 11, the reverse chevron protrusion 47 of the member 25 with cylinder is rotated. Is holding cylinder The member with the cylinder rides on the mountain-shaped protrusion 46 of the member 11 and rises. Therefore, there is an effect that the member with the cylinder can be easily pulled out.
