Description

【０００１】
【産業上の利用分野】
本発明は、化粧品や医薬品など粘性を有する流体物を定量づつ取り出すことができる定量チューブ容器に関するものである。
【０００２】
【従来の技術】
定量押し出しチューブに関する従来例としては、例えば、第６図に示す実公昭６３ー４４３８６８号に開示された考案のように、弁球を用いた定量栓を使用した定量チューブ容器がよく知られている。
【０００３】
従来のこのチューブ容器は、先ずチューブ容器５１を押圧してフイルム弁５２を押し上げて収納液５３を弁座５４内に流入させ、更に収納液５３が水平突起６０上の弁球５５を押し上げて注出口５６を閉鎖するまでチューブ容器５１を押圧する。
【０００４】
次に蓋５７を頚部５８に螺合して蓋５７内に突設された押棒５９で弁球５５を押し下げる。すると収納液５３が下方に押圧されるのでフイルム弁５４も下降して弁座５４を閉鎖する。
【０００５】
続いて蓋５７を取り外し、チューブ容器５１を押圧すると、予め頚部８内に収納されていた一定量の収納液５３を注出口５６より取り出すことができ、上述の操作を繰り返すことによって、その都度収納液５３を定量ずつ取り出すことができると云うものである。
【０００６】
【発明が解決しようとする課題】
ところで、この従来容器にあっては、一度、一定量の収納物を取り出した後、蓋を施して蓋の天井面に突設された押棒を使って弁球を下方に強制的に押し下げないと次の定量押し出し操作が出来ないので、一定量を連続して使用したいときは、いちいち蓋の着脱を繰り返さねばならず不便であった。又、合成樹脂製チューブ容器のようにチューブ自身に自己復元性があり、且つ収納物が低粘度であると、蓋を外している間に負圧によって頚部内の収納物とともに弁自体も引き戻されてしまい、次の定量押し出しが不確実になる。更に、低粘度の収納物のチューブ容器を倒立して使用したとき、弁球が鉄製など重い材料であると弁球の自重が働いて速く注出口を閉塞してしまい、押し出し量が一定しなかった。
【０００７】
本発明は、上記の問題に鑑みてなされたもので、正倒立を問わずいかなる姿勢からでもチューブ容器の押圧を繰り返すことで、連続して一定量の内容物を押し出せる定量チューブ容器を提供することを目的としている。
【０００８】
【課題を解決するための手段】
本発明の請求項１に係わる定量チューブ容器は、流出路が貫設された仕切壁を口頚部内に有するチューブ本体の前記口頚部に、上端に注出口を有する中栓が嵌挿され、更に前記口頚部の内径より小径で弾力性のある材料からなる傘形円板弁が前記流出路の出口側を閉塞して前記仕切壁の中心部に植設されており、前記傘形円板弁は開いて前記流出路を開放するとともに反転して周縁部が前記中栓の下部開口端に当接して閉塞することを特徴としている。
【０００９】
本発明の請求項２に係わる定量チューブ容器は、流出路が貫設された底板を有する受栓の口部に、上端に注出口を有する中栓が嵌挿され、更に前記受栓の内径より小径で弾力性のある材料ならなる傘形円板弁が前記流出路の出口側を閉塞して前記底板の中心部に植設され、前記受栓と中栓と傘形円板弁とからなる定量栓体がチューブ本体の口頚部に嵌挿されており、前記傘形円板弁は開いて前記流出路を開放するとともに反転して周縁部が前記中栓の下部開口端に当接して閉塞することを特徴としている。
【００１０】
【作用】
請求項１に係わる定量チューブ容器にあっては、チューブ本体を押圧すると、内容物は傘形円板弁の軸芯周辺に適宜数貫設された仕切壁の流出路を通って傘形円板弁を押し上げ反転させて前記流出路を開放するとともに、傘形円板弁の周縁部を下部開口端に当接させてこれを閉塞する。流出路が開放され下部開口端が閉塞する間に一定量の内容物が中栓内に押し出される。
【００１１】
次に、チューブ本体の押圧を中止すると、傘形円板弁は弾性力のある材料で成形されているので自己復元性が強く、チューブ本体の弾性力による自己復元の動きよりも閉弁反応が速く働いて、下部開口端を開放するとともに流出路を閉塞して閉弁する。従って、内容物がチューブ本体内に逆流してしまうことがない。
【００１２】
また、傘形円板弁は、中栓の下部開口端で最大開き角度が規制されて閉弁作動の距離が短い上に自己復元性が強いので、中栓内への外気の引き込み量も少なく、内容物の注出口からの液面レベルが高く保てて再押し出しが素早くできる。そして、チューブ本体の正倒立にかかわらず、押圧と中止を繰り返すことにより中栓内に内容物が補充されるので、連続して一定量の内容物を押し出すことができる。
【００１３】
請求項２に係わる定量チューブ容器にあっては、請求項１の作用に加えて、定量機構を栓体として別個に設けてこれをチューブ本体の口頚部に嵌挿した構成としたので、成形時に底部を溶着形成する安価な中空成形方法によるチューブを使用して定量チューブ容器を製作することが可能である。
【００１４】
また、口頚部の内形状が同一であればチューブ本体のデザインや大きさが異なっていても、一組の定量栓体の金型を使用することにより多様な定量チューブ容器が製造できる。
【００１５】
【実施例】
以下、本発明の実施例を添付図面を参照しながら詳細に説明する。
【００１６】
図１ないし図３は、本発明に係わる定量チューブ容器の第１実施例を示したものであり、図４ないし図５は第２実施例を示したもので、これらの図において、符合Ｃはチューブ本体を示している。
【００１７】
図１ないし図５に示すように、本発明に係わる定量チューブ容器のチューブ本体Ｃは、主として合成樹脂製の成形体からなり、チューブ本体Ｃの胴部１４と口頚部３とが一体成形されたものであっても、胴部１４と口頚部３とが個別に成形されて胴部１４の上端で口頚部３の肩部１５とが溶着されたものであってもよいが、本実施例では単層で一体成形されたものについて説明する。
【００１８】
また、胴部１４は、合成樹脂製の単層の筒体や、アルミ薄やガスバリヤー性の高い樹脂などを挟んだ積層体の筒体も使用される。要は、使用目的に沿った適度の弾性と可撓性を兼ね具えた合成樹脂材料であればよい。
【００１９】
図１ないし図３に示す第１実施例の定量チューブ容器は、チューブ本体Ｃの肩部１５にポリエチレンなどの合成樹脂で一体的に成形された口頚部３の外周にキヤップ（図示せず）が螺合される雄螺子１９が螺設され、口頚部３内の下方にチューブ内部と口頚部３内部を区画する仕切壁２が一体的に形成されている。
【００２０】
前記仕切壁２の中心には、傘形円板弁６の軸芯１２が植設された貫通孔１６が設けられているとともに、前記軸芯１２周辺に軸芯１２を囲んで適宜数の流出路１が貫設されて内容物が押し出される通路を形成し、前記傘形円板弁６がこの流出路１の出口側を開閉自在に閉塞して固定されている。
【００２１】
また、前記傘形円板弁６は、周縁部７が薄肉で上面が山形に湾曲に形成された円形の弾性板１３が前記口頚部３の内径よりも小径に設定され、前記弾性板１３の中央下面には前記貫通孔１６からの抜け止めとなる下端が膨出した軸芯１２が一体に垂設されて前記貫通孔１６に脱抜不能に植設されている。
【００２２】
尚、傘形円板弁６は架橋ゴム、ポリエチレンなどの柔軟性の合成樹脂、射出成形用エラストマーなど弾性や柔軟性を合わせ持った材料が使用されている。
【００２３】
一方、前記口頚部３には、上端に注出口４を有し、下部開口端８が開放された筒状の周壁８ａの外周中程にフランジ１７が周設された中栓５が嵌挿されている。
【００２４】
尚、前記中栓５は、前記フランジ１７が口頚部３の開口端１８に当接して、前記中栓５の下部開口端８と前記仕切壁２との間の距離Ｋを残す寸法に設定されて嵌挿されている。
【００２５】
以上のように構成された本実施例のチューブ容器に内容物を充填するときは、胴部１４の下部開口から行われ、底部を熱溶着して密封し、完成品となる。
【００２６】
上述したチューブ本体Ｃを押圧すると、傘形円板弁６の軸芯１２の周辺の仕切壁２に適宜数貫設された流出路１から内容物が押し出される。そして、図２に示すように、傘形円板弁６の弾性板１３は下方から圧力を受けて弾性変形し、薄肉の周縁部７は押し上げられて反転し、流出路１が開放されて中栓５と連通して内容物が押し出される。
【００２７】
次に、押し出しが進むと、図３に示すように、弾性板１３の周縁部７は下部開口端８に当接してこれを閉塞する。流出路１が開放されてから周縁部７が下部開口端８に当接するまでの間に一定量の内容物が中栓５内に押し出される。
【００２８】
そして、チューブ本体Ｃの押圧を中止すると、傘形円板弁６は弾性力のある材料で成形されているので自己復元性が強く、チューブ本体Ｃの弾性力による自己復元の動きよりも閉弁反応が速く働いて、下部開口端８を開放するとともに流出路１を閉塞して閉弁する。従って、内容物がチューブ本体Ｃ内に逆流してしまうことがない。
【００２９】
また、傘形円板弁６は、中栓５の下部開口端８で最大開き角度が規制されて閉弁作動の距離が短い上に自己復元性が強いので、中栓５内への外気の引き込み量も少なく、内容物の注出口４からの液面レベルが高く保てて再押し出しが素早くできる。そして、チューブ本体Ｃの押圧と中止を繰り返すことにより、チューブ本体Ｃないより中栓５内へ内容物が補充されるので、連続して一定量の内容物を押し出すことができる。
【００３０】
図４ないし図５は、本発明に係わる定量チューブ容器の第２実施例を示すものであり、図において、上記第１実施例と共通する部分については同一符合を付しその説明を省略する。
【００３１】
図５に示すように、この第２実施例に係わる定量チューブ容器は、流出路１が貫設された底板９を有する受栓１０の口部１１に、上端に注出口４を有する中栓５が嵌挿され、更に前記受栓１０の内径より小径で弾力性のある材料ならなる傘形円板弁６が前記流出路１の出口側を閉塞して前記底板９の中心部に植設され、前記受栓１０と中栓５と傘形円板弁６とからなる定量栓体Ａがチューブ本体Ｃの口頚部３に挿入されて構成されている（図４を参照）。
【００３２】
本実施例によれば、第１実施例に記載の作用に加えて、傘形円板弁６を主体とする定量機構を定量栓体Ａとして別個に設けてこれを口頚部３に取り付ける構成としたことにより、チューブ本体Ｃの口頚部３から内容物を充填した後にも装着することができるので、成形時に底部が溶着されてしまう安価な中空成形方法によるチューブを使用して定量チューブ容器が製作できる。
【００３３】
更に、本実施例によれば、口頚部３の内形状が同一であればチューブ本体Ｃのデザインや大きさが異なっていても、一つの定量栓体Ａの金型を使用することにより多様な定量チューブ容器が製造できて経済的である。
【００３４】
【発明の効果】
本発明に係わる定量チューブ容器によれば、以下の効果を奏することができる。
【００３５】
請求項１に記載の定量チューブ容器によれば、チューブ本体の正倒立にかかわらず、押圧と中止を繰り返すことにより、連続して一定量の内容物を押し出すことができて使いかってがよい。
【００３６】
また、傘形円板弁は弾性力のある材料で成形されているので自己復元性が強く、チューブ本体自身の弾性力による自己復元の動きよりも閉弁反応が速く働いて閉弁する。従って、内容物がチューブ本体内に逆流してしまうことがなく、閉弁性が確実である。
【００３７】
そして、傘形円板弁は、中栓の下部開口端に当接することにより最大開き角度が規制されて閉弁作動の距離が短い上に自己復元性が強いので、閉弁作動によっておこる外気の中栓内への引き込み量が少なく、内容物の注出口からの液面レベルが高く保てて見栄えが良いうえに、再押し出しが素早く円滑にできる効果がある。

[Industrial applications]
TECHNICAL FIELD The present invention relates to a metering tube container that can take out a viscous fluid such as cosmetics and pharmaceuticals by metering.
[0002]
[Prior art]
As a conventional example of the fixed-quantity extrusion tube, for example, a fixed-quantity tube container using a fixed tap using a valve ball is well known as in the device disclosed in Japanese Utility Model Publication No. 63-443868 shown in FIG. .
[0003]
In this conventional tube container, first, the tube container 51 is pressed to push up the film valve 52 so that the stored liquid 53 flows into the valve seat 54. The tube container 51 is pressed until the outlet 56 is closed.
[0004]
Next, the lid 57 is screwed into the neck 58, and the valve ball 55 is pushed down by the push rod 59 protruding into the lid 57. Then, the stored liquid 53 is pressed downward, so that the film valve 54 is also lowered to close the valve seat 54.
[0005]
Subsequently, when the lid 57 is removed and the tube container 51 is pressed, a certain amount of the stored liquid 53 previously stored in the neck 8 can be taken out from the spout 56, and by repeating the above-described operation, the stored liquid is stored each time. This means that the liquid 53 can be taken out in fixed amounts.
[0006]
[Problems to be solved by the invention]
By the way, in this conventional container, after taking out a certain amount of stored items once, it is necessary to forcibly push down the valve ball downward by applying a lid and using a push rod protruding from the ceiling surface of the lid. Since the next fixed amount extrusion operation cannot be performed, when the user wants to use a fixed amount continuously, the lid must be repeatedly attached and detached, which is inconvenient. In addition, if the tube itself has self-restoring properties such as a synthetic resin tube container and the stored material has low viscosity, the valve itself is pulled back together with the stored material in the neck due to negative pressure while the lid is removed. This makes the next quantitative extrusion uncertain. Furthermore, when a low-viscosity stored tube container is used upside down, if the valve ball is made of a heavy material such as iron, the valve ball's own weight acts and the spout is quickly closed, and the extrusion amount is not constant. Was.
[0007]
The present invention has been made in view of the above problems, and provides a quantitative tube container capable of continuously pushing out a fixed amount of contents by repeatedly pressing the tube container from any posture regardless of whether the head is upside down. It is aimed at.
[0008]
[Means for Solving the Problems]
In the metering tube container according to claim 1 of the present invention, an inner plug having a spout at an upper end is inserted into the mouth and neck portion of the tube body having a partition wall having an outflow passage penetrating the mouth and neck portion. An umbrella-shaped disc valve made of a resilient material having a diameter smaller than the inner diameter of the mouth and neck is closed at the outlet side of the outflow passage and implanted in the center of the partition wall. Is opened to open the outflow passage and invert so that the peripheral edge portion abuts on the lower opening end of the inner plug and is closed.
[0009]
In the metering tube container according to claim 2 of the present invention, an inner plug having a spout at an upper end is inserted into an opening of a stopper having a bottom plate through which an outflow passage is provided, and the inner diameter of the stopper is further determined. An umbrella-shaped disc valve made of a small-diameter and elastic material is closed at the outlet side of the outflow passage and is implanted at the center of the bottom plate, and includes the stopper, the inner stopper, and the umbrella-shaped disc valve. A metering plug is inserted into the mouth and neck of the tube body, and the umbrella-shaped disc valve opens to open the outflow passage and turns over to close the peripheral edge against the lower opening end of the inner plug. It is characterized by doing.
[0010]
[Action]
In the metering tube container according to claim 1, when the tube main body is pressed, the contents pass through the outflow passages of the partition wall provided in a suitable number around the axis of the umbrella-shaped disk valve, and the contents are umbrella-shaped. The outflow path is opened by pushing up and reversing the valve, and the peripheral edge of the umbrella-shaped disc valve is brought into contact with the lower opening end to close it. While the outflow channel is open and the lower opening end is closed, a certain amount of the contents is pushed into the inner plug.
[0011]
Next, when the pressing of the tube body is stopped, the umbrella-shaped disc valve is formed of an elastic material, so that the self-restoring property is strong, and the valve closing reaction is more intense than the self-restoring movement by the elastic force of the tube body. Working fast, opening the lower opening end, closing the outflow passage and closing the valve. Therefore, the contents do not flow back into the tube body.
[0012]
In addition, the umbrella-shaped disc valve has a maximum opening angle regulated by the lower opening end of the inner plug, shortens the valve closing operation distance, and has a strong self-recovery property, so the amount of outside air drawn into the inner plug is small. The liquid level from the spout of the contents can be kept high, and re-extrusion can be performed quickly. Then, irrespective of the inversion of the tube main body, the contents are replenished in the inner plug by repeatedly pressing and stopping, so that a certain amount of contents can be continuously pushed out.
[0013]
In the metering tube container according to claim 2, in addition to the function of claim 1, the metering mechanism is separately provided as a plug body, which is inserted into the mouth and neck of the tube body. It is possible to manufacture a fixed-quantity tube container using a tube formed by an inexpensive hollow molding method in which a bottom is formed by welding.
[0014]
In addition, if the inner shape of the mouth and neck is the same, even if the design and size of the tube main body are different, various quantitative tube containers can be manufactured by using a set of quantitative stopper molds.
[0015]
【Example】
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0016]
FIGS. 1 to 3 show a first embodiment of a quantitative tube container according to the present invention, and FIGS. 4 and 5 show a second embodiment. In these figures, the symbol C is used. 3 shows a tube body.
[0017]
As shown in FIGS. 1 to 5, the tube main body C of the quantitative tube container according to the present invention is mainly made of a molded product made of a synthetic resin, and the body 14 and the mouth and neck 3 of the tube main body C are integrally formed. Alternatively, the torso 14 and the mouth and neck 3 may be formed separately and the upper end of the torso 14 and the shoulder 15 of the mouth and neck 3 may be welded. A single-layer monolithic molding will be described.
[0018]
The body 14 may be a single-layer cylinder made of a synthetic resin, or a multilayer cylinder sandwiching a thin aluminum or resin having a high gas barrier property. In short, any synthetic resin material having appropriate elasticity and flexibility according to the purpose of use may be used.
[0019]
In the metering tube container of the first embodiment shown in FIGS. 1 to 3, a cap (not shown) is provided on the outer periphery of the mouth and neck portion 3 integrally formed of a synthetic resin such as polyethylene on the shoulder portion 15 of the tube body C. A male screw 19 to be screwed is screwed, and a partition wall 2 for dividing the inside of the tube and the inside of the mouth and neck 3 is integrally formed below the inside of the mouth and neck 3.
[0020]
At the center of the partition wall 2, there is provided a through hole 16 in which the shaft core 12 of the umbrella-shaped disc valve 6 is planted. The passage 1 is formed to form a passage through which the contents are extruded, and the umbrella-shaped disc valve 6 is fixed by closing the outlet side of the outflow passage 1 so as to be openable and closable.
[0021]
The umbrella-shaped disc valve 6 is configured such that a circular elastic plate 13 whose peripheral portion 7 is thin and whose upper surface is curved in a mountain shape is set to have a smaller diameter than the inner diameter of the mouth and neck portion 3. A shaft core 12 having a lower end that protrudes from the through-hole 16 and that protrudes downward is integrally provided on the lower surface of the center, and is implanted in the through-hole 16 so that it cannot be removed.
[0022]
The umbrella-shaped disc valve 6 is made of a material having both elasticity and flexibility, such as a flexible synthetic resin such as crosslinked rubber and polyethylene, and an elastomer for injection molding.
[0023]
On the other hand, an inner plug 5 having a spout 4 at the upper end and a flange 17 provided in the middle of the outer periphery of a cylindrical peripheral wall 8a having an open lower end 8 is fitted into the mouth and neck portion 3. ing.
[0024]
The inner plug 5 is set to have such a size that the flange 17 abuts on the opening end 18 of the mouth-neck portion 3 and leaves a distance K between the lower opening end 8 of the inner plug 5 and the partition wall 2. It is inserted.
[0025]
When filling the tube container of the present embodiment configured as described above with the contents, the filling is performed from the lower opening of the body portion 14, and the bottom portion is heat-sealed and sealed to obtain a finished product.
[0026]
When the above-mentioned tube main body C is pressed, the contents are pushed out from the outflow passages 1 provided in the partition walls 2 around the shaft core 12 of the umbrella-shaped disc valve 6 as appropriate. Then, as shown in FIG. 2, the elastic plate 13 of the umbrella-shaped disc valve 6 is elastically deformed by receiving pressure from below, the thin peripheral portion 7 is pushed up and inverted, and the outflow passage 1 is opened and the middle portion is opened. The contents are extruded in communication with the stopper 5.
[0027]
Next, as the extrusion proceeds, as shown in FIG. 3, the peripheral portion 7 of the elastic plate 13 contacts the lower opening end 8 to close it. From the opening of the outflow passage 1 to the time when the peripheral portion 7 abuts on the lower opening end 8, a certain amount of the content is pushed into the inner plug 5.
[0028]
Then, when the pressing of the tube body C is stopped, the umbrella-shaped disc valve 6 is formed of a material having elasticity, so that the self-restoring property is strong, and the valve closes more than the self-restoring movement by the elastic force of the tube body C. The reaction works fast, opening the lower opening end 8 and closing and closing the outflow passage 1. Therefore, the contents do not flow back into the tube body C.
[0029]
Further, the umbrella-shaped disc valve 6 has a maximum opening angle regulated by the lower opening end 8 of the inner plug 5 to shorten the valve closing operation distance and has a strong self-recovery property. The amount of drawing in is small, and the liquid level from the spout 4 of the contents can be kept high, so that re-extrusion can be performed quickly. Then, by repeatedly pressing and stopping the tube main body C, the contents are replenished into the inner plug 5 without the tube main body C, so that a constant amount of the contents can be continuously extruded.
[0030]
FIGS. 4 and 5 show a second embodiment of the quantitative tube container according to the present invention. In the drawings, the same reference numerals are given to the same parts as those in the first embodiment, and description thereof will be omitted.
[0031]
As shown in FIG. 5, the metering tube container according to the second embodiment has an inner plug 5 having a spout 4 at an upper end at a mouth 11 of a stopper 10 having a bottom plate 9 through which an outflow passage 1 is provided. And an umbrella-shaped disc valve 6 made of a resilient material smaller in diameter than the inner diameter of the stopper 10 closes the outlet side of the outflow passage 1 and is implanted in the center of the bottom plate 9. A fixed amount plug A comprising the receiving plug 10, the inner plug 5, and the umbrella-shaped disc valve 6 is inserted into the mouth and neck 3 of the tube body C (see FIG. 4).
[0032]
According to the present embodiment, in addition to the operation described in the first embodiment, a configuration in which a metering mechanism mainly composed of an umbrella-shaped disc valve 6 is separately provided as a metering plug A and attached to the mouth and neck 3 is provided. As a result, since the tube can be mounted even after the contents are filled from the mouth and neck 3 of the tube body C, a fixed-quantity tube container is manufactured using an inexpensive tube formed by an inexpensive hollow molding method in which the bottom is welded during molding. it can.
[0033]
Furthermore, according to the present embodiment, if the inner shape of the mouth and neck 3 is the same, even if the design and size of the tube main body C are different, various molds can be obtained by using one mold of the fixed amount plug A.

【The invention's effect】
According to the metering tube container according to the present invention, the following effects can be obtained.
[0035]
According to the metering tube container according to the first aspect, regardless of whether the tube main body is upside down, by repeatedly pressing and stopping, it is possible to continuously push out a certain amount of contents and use it.
[0036]
In addition, since the umbrella-shaped disc valve is formed of a material having elasticity, the self-restoring property is strong, and the valve closing reaction works faster than the self-restoring movement by the elastic force of the tube body itself to close the valve. Therefore, the contents do not flow back into the tube main body, and the valve closing property is ensured.
[0037]
The umbrella-shaped disc valve is in contact with the lower opening end of the inner plug, so that the maximum opening angle is regulated, the distance of the valve closing operation is short, and the self-restoring property is strong. The amount of liquid drawn into the inner stopper is small, the level of the liquid from the spout of the contents can be kept high, the appearance is good, and the re-extrusion can be performed quickly and smoothly.
[0038]
According to the metering tube container according to claim 2, in addition to the effects described in the first embodiment, since the metering mechanism is separately provided as a metering plug and attached to the mouth and neck of the tube body, A fixed-quantity tube container can be manufactured using an inexpensive hollow molding method in which the bottom is welded during molding.
[0039]
Also, if the inner shape of the mouth and neck is the same, even if the design and size of the tube body are different, a variety of quantitative tube containers can be prepared by using a set of It can be manufactured and is economical.
