Description

【０００１】
【発明の属する技術分野】
本発明は計量式塗布容器に関する。
【０００２】
【従来の技術】
例えば実開平4-29961 号が示すように、弾性圧搾可能に設けた容器体口頸部に計量液貯溜筒を装着させた計量式塗布容器が知られている。尚その計量液貯溜筒は、容器体胴部圧搾と該胴部の弾性復元により液体計量できる機構を有し、かつ上端には、頂板上面から突出する塗布棒押込みにより計量液貯溜筒内液体が塗布棒を挿通させた頂板透孔から流出し、塗布棒解放による弾性復帰でその透孔が閉じ、液体流出が停止するよう設けられた流出機構を有している。
【０００３】
【発明が解決しようとする課題】
上記従来容器は、容器体胴部を弾性圧搾可能に形成することが必要であり、その圧搾変形がし易いと塗布棒先端を被塗布面へ押付けて行う塗布時に容器体内高圧化により液体が出過ぎることがあり、又圧搾変形し難いと当然その圧搾操作が面倒があった。
【０００４】
本発明は、そのような欠点、面倒を除去して弾性変形しない容器体に対しても使用でき、塗布時における液体流出量を常にほぼ一定に保つことが可能に形成したものである。
【０００５】
第１の手段として胴部内と連通して起立する口筒部10の下部内面から、内向きフランジ８を介して計量室形成用短筒９を起立する容器体１と、上記口筒部10へ、一定ストローク上下動可能にかつ水密に嵌合させた周壁22を頂板23外周から垂下し、かつ頂板23には注出孔を有する計量液貯溜筒21と、計量液貯溜筒 21 内面から窓孔付き栓体保持筒 31 を介して垂下させると共に、容器体１に対する計量液貯溜筒 21 の上下動で計量室形成用短筒９の筒孔を開閉する栓体 35とを備え、上記注出孔は、該注出孔を通って上方突出する塗布棒45の押下げと、該塗布棒45を有する基板44の弾性復帰とで開閉する、吐出弁46で閉塞させ、上記計量室形成用短筒９を合成樹脂で形成するとともに、計量室形成用短筒９の上端部を内方へ折り返し形成し、該折り返し部分に栓体 35 を嵌合させる如く構成した。
【０００６】
第２の手段として、上記第１の手段を有すると共に上記容器体１を、胴部上端から口頸部５を起立する容器本体２と、上記口頸部外面へ回動不能に嵌合させた装着筒７の上端から内向きフランジ８を介して計量室形成用短筒９を起立し、かつ該短筒外面との間に間隙をおいて、内向きフランジから口筒部10を起立する連結筒６とで形成し、
上記口筒部10を雄ねじ筒に、かつ計量液貯溜筒の周壁22を雌ねじ筒に、それぞれ形成してそれ等両筒を螺合させると共に、口筒部10の上部外面と周壁22の中間部内面とには、互いに係合して計量液貯溜筒21の上限を定める第１、第２係合突条13,25 を周設した。
【０００７】
第３の手段として、上記第１又は第２の手段を有すると共に上記計量液貯溜筒21の頂板23を、上部小径のテーパ状筒として該テーパ状筒上端部に穿設した透孔周縁からノズル24を起立させると共に、
上記頂板23の外周部内面に嵌着させた上端筒部32から上部小径のテーパ状コイルスプリング43を起立させ、該スプリング上端に付設させた基板44上面の中心部からノズル内を上下動可能に挿通させて起立させた塗布棒45の上部をノズル上方まで突出させた吐出弁部材41を設けて、上記透孔下面外周部と、該外周部へ上記スプリングの付勢により弾性圧接する基板44の上面とで吐出弁46を形成し、
上記塗布棒45上端部を付勢に抗して押下げることで開弁可能に形成した。
【０００８】
【発明の実施の形態】
以下図面について説明すると、１は容器体である。該容器体は図示例において、容器本体２と連結筒６とで形成しており、容器本体は、胴部３上端から肩部４を介して口頸部５を起立する。連結筒６は、上記口頸部５外面へ回動不能に嵌合させた装着筒７の上端から内向きフランジ８を介して計量室形成用短筒９を起立させ、かつ該短筒外面との間に間隙をおいて、内向きフランジから口筒部10を起立する。容器本体と連結筒６とを水密に嵌合させるため、内向きフランジ８から第１シール筒11を口頸部内面に接して垂下させており、後述の栓体の着脱を容易かつ確実とするため、計量室形成用短筒９の上端部は内方へ折返している。該短筒は口筒部10と間隙を塗布液計量室12とするもので、口筒部10はその下半を雄ねじ筒とし、かつ上端外面に第１係合突条13を周設している。
【０００９】
21は計量液貯溜筒で、上記口筒部10外面へ、一定ストローク上下動可能に、かつ水密に嵌合させた周壁22を頂板23外周から垂下し、かつ頂板中央部には透孔を穿設し、かつ透孔周縁からノズル24を起立している。その頂板は液体塗布の便利のため上部小径のテーパ状とするがよく、図示例ではその上端から内向きフランジを介して上記ノズルを起立させている。周壁22はその下半を雌ねじ筒とし、かつ中間部内面に第２係合突条25を周設している。又頂板からは口筒部10内面に水密に接して摺動する第２シール筒26を、上記第２係合突条25下方まで垂設している。
【００１０】
31は栓体保持筒で、上端筒部32を上記第２シール筒26の上端部内面へ嵌着させ、かつ該上端筒部から内向きフランジを介して複数の窓孔33付きで下部小径のテーパ状筒34を垂下し、かつ該テーパ状筒下端に、既述計量室形成用短筒９の筒孔開閉用の栓体35を付設している。
【００１１】
41は吐出弁部材で、上記内向きフランジ上面へ載置させて上端筒部32内面へ嵌合させた短筒42の下端内面から内向きフランジを介して、上部小径のテーパ状コイルスプリング43を起立し、該スプリング上端に付設させた基板44の上面中心部から、既述ノズル24内へ挿通させて塗布棒45をノズル上方まで起立させている。基板44外周部は下方大径のテーパ状としてノズル下端面、即ちノズル孔下面外周部へ水密に圧接させ、それ等基板外周部上面とノズル孔下面外周部とで吐出弁46を形成している。塗布棒45の下端部を除く部分には図示のように複数の縦溝47を縦設するとよく、塗布棒45を下限まで押下げたとき、それ等縦溝下端はノズル孔下端よりも下方に位置してそれ等縦溝が計量液貯溜筒21内からの液体流出路を形成するよう設けている。
【００１２】
尚、51はキャップである。
【００１３】
上記各部材はそれぞれ合成樹脂材で形成している。
【００１４】
上記構成において、図１の状態からキャップ51を外し、図２のように計量液貯溜筒21を容器体１に対し上昇させて計量室形成短筒９上端を開口させる。該状態から容器を倒立させ、かつ復帰させることで上記短筒９と口筒部10との間が形成する計量室12内に液体を入れ計量することが出来るから、該状態から計量液貯溜筒21を下降させて計量室形成用短筒９の上端面を栓体35で閉塞し、次いで図３のように容器を倒立させて塗布棒45上端面を被塗布面に押付けることで吐出弁46が開き、縦溝47内を通って流下する液体を塗布することが出来る。塗布棒の押付けを離すとコイルスプリング43の弾性復元で吐出弁46が閉塞して塗布液体の流下を停止する。
【００１５】
【発明の効果】
本発明は既述構成とするもので、第１の手段のようにすることで、容器体胴部を弾性圧搾可能に形成する必要がなく、又栓体35が計量室形成用短筒９を密閉する状態で容器体内は完全に密閉されることとなるから、該状態では胴部圧搾により容器体内が高圧化しても、計量液貯溜筒内の計量された液体に影響を与えることは全くなく、よって塗布液が予定された流量以上に多くなることがなく、従って塗布液を被塗布面全体にわたってほぼ均等に塗ることが出来る。
【００１６】
第２の手段のように口筒部10と計量液貯溜筒の周壁22とを螺合させることで、栓体35の着脱を確実かつ容易とすることが出来、又計量液貯溜筒21の上限を定めることで、その抜出しを防止できる。
【００１７】
第３の手段のようにすることで、計量液貯溜筒21の周壁上面から頂板23およびノズル24が上方突出することとなり、よって塗布の際に上記周壁外周部が邪魔となることがなく、又吐出弁の開閉を確実とすることが出来る。

DETAILED DESCRIPTION OF THE INVENTION
In the following description of the drawings, 1 is a container body. In the illustrated example, the container body is formed of a container main body 2 and a connecting cylinder 6, and the container main body erects the mouth and neck portion 5 from the upper end of the trunk portion 3 through the shoulder portion 4. The connecting tube 6 erects a measuring tube forming short tube 9 through an inward flange 8 from the upper end of the mounting tube 7 that is non-rotatably fitted to the outer surface of the mouth-and-neck portion 5, and the outer surface of the short tube The mouth tube portion 10 is erected from the inward flange with a gap therebetween. In order to fit the container body and the connecting cylinder 6 in a watertight manner, the first seal cylinder 11 is suspended from the inward flange 8 in contact with the inner surface of the mouth and neck portion, so that the plug body described later can be easily and reliably attached and detached. Therefore, the upper end portion of the measuring chamber forming short cylinder 9 is turned inward. The short tube has a gap between the mouth tube portion 10 and the coating liquid measuring chamber 12. The mouth tube portion 10 has a lower half as a male screw tube, and a first engaging protrusion 13 is provided around the upper end outer surface. Yes.
[0009]
21 is a metering liquid storage cylinder. A peripheral wall 22 that is watertightly fitted to the outer surface of the mouth cylinder part 10 so as to be movable up and down for a fixed stroke is suspended from the outer periphery of the top plate 23, and a through hole is formed in the central part of the top plate. The nozzle 24 is erected from the periphery of the through hole. The top plate is preferably tapered with a small diameter at the top for the convenience of liquid application. In the illustrated example, the nozzle is erected from the upper end through an inward flange. The lower end of the peripheral wall 22 is a female screw cylinder, and a second engagement protrusion 25 is provided around the inner surface of the intermediate portion. Further, a second seal cylinder 26 that slides in contact with the inner surface of the mouth tube portion 10 in a watertight manner is suspended from the top plate to the lower side of the second engagement protrusion 25.

From the center of the upper surface of the substrate 44 that is erected and attached to the upper end of the spring, the coating rod 45 is erected to the upper side of the nozzle by being inserted into the nozzle 24 described above. The outer periphery of the substrate 44 is tapered downward and has a large diameter, and is in watertight pressure contact with the lower end surface of the nozzle, that is, the outer periphery of the lower surface of the nozzle hole. . As shown in the figure, a plurality of vertical grooves 47 may be provided vertically on the portion excluding the lower end of the application bar 45. When the application bar 45 is pushed down to the lower limit, the lower ends of the vertical grooves are located below the lower end of the nozzle hole.

【The invention's effect】
The present invention has the above-described configuration. By using the first means , it is not necessary to form the container body so as to be elastically squeezable, and the plug body 35 is provided with the measuring chamber forming short tube 9. Since the container body is completely sealed in a sealed state, there is no influence on the measured liquid in the measuring liquid storage cylinder even if the container body is pressurized by the trunk squeezing. Therefore, the coating liquid does not increase more than the predetermined flow rate, and therefore the coating liquid can be applied almost uniformly over the entire surface to be coated.
