本発明は、蓋体等を装着可能な口部に中栓を嵌着する中栓付き容器に関し、とくに中栓を口部から取り外しやすいように、中栓に摘み部を設けた中栓付き容器に関するものである。  TECHNICAL FIELD The present invention relates to a container with an inner plug for fitting an inner plug to a mouth part to which a lid or the like can be attached, and in particular, a container with an inner plug provided with a knob on the inner plug so that the inner plug can be easily removed from the mouth part. It is about.

容器の口部に注出口を備えた中栓を気密に嵌合し、当該注出口から内容物を注出して使用する中栓付き容器はよく知られている。
このような中栓付き容器を廃棄する際には、容器と中栓の材質が異なる場合、容器から中栓を取り外して分別廃棄する必要がある。
また、内容物を密封する中栓を使用時に取り外して、口部から内容物を注出したり、口部に噴射ポンプ等の他の注出具を取り付けたりする中栓付き容器もよく知られている。A container with an inner stopper that is used by sealingly fitting an inner stopper provided with a spout at the mouth portion of the container and discharging the contents from the spout is well known.
When discarding such a container with a stopper, if the container and the stopper are made of different materials, it is necessary to remove the stopper from the container and dispose of it separately.
Also well known is a container with an inner stopper that removes the inner stopper that seals the contents when in use and pours out the contents from the mouth or attaches another pouring tool such as a jet pump to the mouth. .

このように容器の口部に嵌合する中栓は、口部から容易に離脱しないようにしっかり嵌着されているので、通常は取り外すことが困難である。
そこで、口部に嵌着された中栓を、必要に応じて容易に取り外すことができるように、中栓に摘み部を設け、摘み部を引っ張ることで取り外しやすくした中栓付き容器が従来より知られている（例えば、特許文献１、２参照）。Since the inner plug that fits into the mouth portion of the container is firmly fitted so as not to be easily detached from the mouth portion, it is usually difficult to remove.
Therefore, a container with an inner plug that has been provided with a knob and easily removed by pulling the knob so that the inner plug fitted to the mouth can be easily removed as necessary has been conventionally used. Known (see, for example,Patent Documents 1 and 2).

しかしながら、上記特許文献１記載のツマミ片付中栓は、中栓の上縁鍔輪１に、その一部を外方へ膨出させたツマミ片２を突設しただけのものであり、螺合蓋Ｂを閉めるときは、当該ツマミ片２を下方に屈折し、螺合蓋Ｂと瓶口の螺合溝３，４の間に挟んで螺合するものである。
そのため、閉蓋するときに常に手指でツマミ片２を押下げ、瓶口に密着させながら螺合蓋Ｂを螺合しなければならず面倒であるとともに、螺合状態が不整合となって螺合蓋Ｂが不用意に外れたり、開閉の都度螺合を繰り返すことによってツマミ片２が損傷して、ちぎれてしまうという問題があった。However, the inner plug with a knob piece described in the above-mentionedpatent document 1 is obtained by projecting aknob piece 2 having a part bulged outwardly on theupper edge collar 1 of the inner plug. When closing the mating lid B, theknob piece 2 is bent downward and is screwed between the screwing lid B and the screwing grooves 3 and 4 of the bottle mouth.
Therefore, when closing the lid, theknob piece 2 is always pushed down with fingers, and the screwed lid B must be screwed in close contact with the bottle mouth, and the screwed state becomes inconsistent and screwed. There is a problem that thetab 2 is damaged by tearing the mating lid B carelessly or repeatedly screwing each time it is opened and closed.

上記特許文献２記載の摘み板３０を設けた中栓２１は、頂板外周から逆Ｌ字状に突設した摘み板３０を、容器体口頸部の周面に設けた凹溝４に嵌合させているので、上記特許文献１記載のツマミ片付中栓のような問題は生じないが、凹溝４から摘み板３０を引き出すときに、凹溝４の側部に妨げられて手指で摘みにくい。
しかも、摘み板３０は頂板外周から逆Ｌ字状に突出した形状で成形され、凹溝４の底部周面に沿って内向きに湾曲して垂下しているため、摘み板３０をめくり上げるために反転屈曲させる際の抵抗力が大きく、さらに、成形時の形状に戻ろうとする復元力が働くため、手指が摘み板３０に掛かっても、摘み板３０を凹溝４から引き出しにくいという問題があった。Theinner plug 21 provided with theknob plate 30 described inPatent Document 2 is fitted with theknob plate 30 protruding in an inverted L-shape from the outer periphery of the top plate into the groove 4 provided on the peripheral surface of the container neck. However, when thepulling plate 30 is pulled out from the groove 4, it is hindered by the side of the groove 4 and picked with fingers. Hateful.
Moreover, since theknob plate 30 is formed in a shape protruding in an inverted L shape from the outer periphery of the top plate, and is bent inwardly along the bottom peripheral surface of the groove 4, theknob plate 30 is turned up. In addition, since the resistance force when reversing and bending is large, and the restoring force to return to the shape at the time of molding works, there is a problem that it is difficult to pull thegrip plate 30 out of the groove 4 even if a finger hits thegrip plate 30. there were.

本実施例では、ヒンジ部１３は外筒１２の下端部で連設しているが、必ずしも下端部でなくともよく、例えば、平坦面部２１の中程や上部で連設するなど、必要に応じて変更が可能である。
また、本実施例では、ヒンジ部１３と摘み部１４は同じ幅を有しているが、ヒンジ部１３の幅は摘み部１４のそれより狭くてもよく、平坦面部２１の幅は、少なくともヒンジ１３の幅以上であればよい。
さらに、本実施例では、摘み部１４の嵌合孔２２を凹溝８の凸部９に嵌合するようにしているが、嵌合孔２２は嵌合凹部であってもよく、さらに、摘み部１４の側に嵌合凸部を設け、凹溝８の側に、該嵌合凸部に嵌合する凹部を設けてもよい。In the present embodiment, thehinge portion 13 is continuously provided at the lower end portion of theouter cylinder 12, but is not necessarily the lower end portion. For example, thehinge portion 13 is continuously provided in the middle or upper portion of theflat surface portion 21 as necessary. Can be changed.
In the present embodiment, thehinge portion 13 and theknob portion 14 have the same width. However, thehinge portion 13 may be narrower than that of theknob portion 14, and theflat surface portion 21 has at least a hinge width. The width may be 13 or more.

本実施例では、中栓Ｃの係合突部２０は、下端にヒンジ部１３が連設された外筒１２の内周側にも設けられているが、本実施例の変形例として、図２（ｂ）に示すように、当該部位の係合突部２０に切り欠き部３０を設けてもよい。
このように、ヒンジ部１３が連設された部位、すなわち平坦面部２１に対応する部位に係合突部２０が形成されていないと、摘み部１４を引っ張ったときに、摘み部１４が連設する付近では嵌合突条６と係合されていないので、外筒１２が変形しやすく、さらに容器Ａの口部１から取り外しやすくなる。
なお、係合突条２０の代わりに、当該部位に対応する容器Ａの嵌合突条６に、同様の趣旨で切り欠き部を設けてもよい。In the present embodiment, the engagingprotrusion 20 of the inner plug C is also provided on the inner peripheral side of theouter cylinder 12 having thehinge portion 13 connected to the lower end. As shown in FIG. 2 (b), anotch 30 may be provided in the engagingprojection 20 of the part.
As described above, when the engagingprotrusion 20 is not formed at a portion where thehinge portion 13 is continuously provided, that is, a portion corresponding to theflat surface portion 21, theknob 14 is continuously provided when theknob 14 is pulled. Since it is not engaged with the fitting protrusion 6 in the vicinity, theouter cylinder 12 is easily deformed and further easily detached from themouth 1 of the container A.
Instead of the engagingprotrusion 20, a notch may be provided in the fitting protrusion 6 of the container A corresponding to the part for the same purpose.

次に、本実施例の使用態様と作用効果について説明する。
まず、容器Ａに中栓Ｃを装着するには、中栓Ｃの摘み部１４と容器Ａの凹溝８との周方向位置を合わせ、内筒１１と外筒１２との間の嵌合溝に口部１の上部筒２をあてがい、上方から押圧する。
押圧にともなって中栓Ｃが降下し、外筒１２はわずかに変形しながら、係合突部２０が嵌合突条６を乗り越えて口部１の環状溝部７に嵌合する。Next, usage modes and operational effects of this embodiment will be described.
First, in order to attach the inner stopper C to the container A, the circumferential positions of theknob 14 of the inner stopper C and theconcave groove 8 of the container A are matched, and the fitting groove between theinner cylinder 11 and theouter cylinder 12 is aligned. Theupper tube 2 of themouth portion 1 is applied to and pressed from above.
With the pressing, the inner plug C is lowered, and theouter cylinder 12 is slightly deformed, and the engagingprotrusion 20 gets over the fitting protrusion 6 and is fitted into theannular groove 7 of themouth portion 1.

中栓Ｃの外筒１２の下端から水平に延びている摘み部１４を、薄肉になっているヒンジ部１３で下方に折り曲げ、嵌合孔２２を凹溝８の凸部９に嵌合する。
凹溝８は、摘み部１４が収容されたときに、摘み部１４の表面がねじ部５に螺合する蓋体のねじの山部より高くならないような深さに形成されている。
摘み部１４の嵌合孔２２は、わずかに締まり嵌めとなる程度に凸部９に圧入され、摘み部１４が、簡単に凸部９から外れて凹溝８から飛び出さないようになっている。
そのため、蓋体Ｂをねじ部５に螺合して口部１に装着する際、中栓Ｃの摘み部１４は凹溝８に確実に収容されているため、螺合の際に邪魔になることはなく、蓋体Ｂを繰り返し着脱しても摘み部１４を損傷することはない。Theknob portion 14 extending horizontally from the lower end of theouter cylinder 12 of the inner plug C is bent downward by thethin hinge portion 13, and thefitting hole 22 is fitted to theconvex portion 9 of thegroove 8.
Theconcave groove 8 is formed to such a depth that the surface of theknob portion 14 does not become higher than the screw thread portion of the lid body screwed into thescrew portion 5 when theknob portion 14 is accommodated.
Thefitting hole 22 of theknob portion 14 is press-fitted into theconvex portion 9 to such an extent that a slight interference fit is achieved, so that theknob portion 14 does not easily come off theconvex portion 9 and jump out of theconcave groove 8. .
Therefore, when the lid B is screwed to thescrew portion 5 and attached to themouth portion 1, theknob portion 14 of the inner plug C is securely accommodated in theconcave groove 8, and therefore becomes an obstacle when screwing. There is nothing, and theknob 14 is not damaged even if the lid B is repeatedly attached and detached.

その後、中栓Ｃを取り外すときには、摘み部１４の先端に手指をかけて外方に引っ張り、凸部９から嵌合孔２２を外して、摘み部１４をヒンジ部１３で上方に折り曲げて引き上げると、外筒１２がわずかに変形しながら係合突部２０の嵌合突条６との係合が解除され、中栓Ｃを口部１から取り外すことができる。
この際、外筒１２の外周面に平坦面部２１が形成され、その下端にヒンジ部１３を介して平板状の摘み部１４が連設されているので、平板状の摘み部１４は、外方への曲げ変形が容易でつまみやすく、かつ、ヒンジ部１３で容易に変形するので、摘み部１４を凹溝８から簡単に引き出すことができるとともに、平坦面部２１に対応する外筒１２の肉厚が比較的小さいため、変形しやすく容易に取り外すことができる。Thereafter, when removing the inner plug C, if the finger is applied to the tip of theknob part 14 and pulled outward, thefitting hole 22 is removed from theconvex part 9, and theknob part 14 is bent upward at thehinge part 13 and pulled up. While theouter cylinder 12 is slightly deformed, the engagement of theengagement protrusion 20 with the fitting protrusion 6 is released, and the inner plug C can be removed from themouth 1.
At this time, since theflat surface portion 21 is formed on the outer peripheral surface of theouter cylinder 12 and the flat plate-like knob portion 14 is continuously provided at the lower end via thehinge portion 13, the flat plate-like knob portion 14 is disposed outward. Can be easily bent and deformed, and can be easily deformed by thehinge portion 13, so that theknob portion 14 can be easily pulled out from thegroove 8 and the thickness of theouter cylinder 12 corresponding to theflat surface portion 21. Is relatively small, it is easy to deform and can be easily removed.

また、中栓Ｃは、摘み部１４およびヒンジ部１３が外筒１２の下端から水平に延びた形状で成形されているので、摘み部１４には常に水平方向に戻ろうとする復元力が働き、嵌合孔２２と凸部９との嵌合を解除すれば、摘み部１４は自律的に立ち上がって凹溝８から外れ、さらに引き出しやすくなっている。  Moreover, since the knob | pickpart 14 and thehinge part 13 are shape | molded in the shape where the knob | pickpart 14 and thehinge part 13 extended horizontally from the lower end of theouter cylinder 12, the restoring force which always tries to return to a horizontal direction acts on the knob | pickpart 14, If the fitting between thefitting hole 22 and theconvex portion 9 is released, theknob portion 14 rises autonomously and comes off theconcave groove 8 and is more easily pulled out.

本実施例では、容器Ａに蓋体Ｂを装着する係合手段として、ねじ部５を採用しているが、必ずしもねじである必要はなく、フック状の係合部など他の係合手段であってもよい。
また、本実施例では、中栓Ｃに注出口１５を設け、注出口１５を封止する蓋体Ｂを開閉することによって容器を使用しているが、中栓Ｃは注出口を有するものに限らず、単なる密封栓等であってもよく、ねじ部５に螺合して口部１に装着する部材は、蓋体に限らなくてもよい。
図５に示すように、中栓Ｃを取り外して噴射ポンプＤを取り付けるようにしてもよく、本発明の中栓付き容器は、必要に応じて多様な形態で使用可能である。In this embodiment, the threadedportion 5 is employed as the engaging means for attaching the lid B to the container A. However, the threadedportion 5 is not necessarily a screw, and other engaging means such as a hook-shaped engaging portion are used. There may be.
Further, in this embodiment, a container is used by providing aspout 15 in the inner plug C and opening and closing the lid B that seals thespout 15, but the inner plug C has a spout. The member is not limited to a lid, and the member that is screwed into thescrew portion 5 and attached to themouth portion 1 is not limited to the lid.
As shown in FIG. 5, the inner plug C may be removed and the injection pump D may be attached, and the container with an inner plug of the present invention can be used in various forms as required.

次に、中栓Ｃの摘み部１４の構成を変更した第２実施例について説明する。
以下、第１実施例と同一の構成部分には同一の符号を用い、第１実施例との相違点を中心に説明する。Next, a second embodiment in which the configuration of theknob 14 of the inner plug C is changed will be described.
Hereinafter, the same reference numerals are used for the same components as those in the first embodiment, and the differences from the first embodiment will be mainly described.

図４に示すように、本実施例の中栓Ｃの摘み部１４には、上面両側部に、摘み部１４が凹溝８に嵌入され蓋体がねじ部５に螺合されたとき、蓋体のねじの山部に略一致する高さに突出する縦リブ２４が設けられている。
摘み部１４は、縦リブ２４を設けることによって、蓋部Ｂがねじ部５に螺合されるとき、縦リブ２４の表面に蓋部Ｂのねじ頭が当接し、凹溝８に確実に収容されるので、摘み部１４が、凹溝８から浮き上がってねじ部５に噛み込まれたりすることを防止することができる。As shown in FIG. 4, when theknob portion 14 is fitted into theconcave groove 8 on both sides of the upper surface and the lid body is screwed to thescrew portion 5,Longitudinal ribs 24 are provided that protrude to a height that substantially coincides with the threads of the body.
Theknob 14 is provided with thevertical rib 24 so that when the lid B is screwed to thescrew portion 5, the screw head of the lid B comes into contact with the surface of thevertical rib 24 and is securely accommodated in theconcave groove 8. Therefore, it is possible to prevent theknob portion 14 from being lifted from thegroove 8 and being bitten by thescrew portion 5.

縦リブ２４は、摘み部１４の先端まで両側部全体にわたって設けてもよいが、摘み部１４の曲げ変形を容易にしてつまみやすくするためには、図４に示す本実施例のように、摘み部１４のヒンジ部１３との連設部位から中央付近まで、すなわち嵌合孔２２付近までとした方がよい。
本実施例は、その他の構成では実施例１と同様であり、縦リブ２４による上記作用効果以外の作用効果は、実施例１と同様である。Thevertical ribs 24 may be provided over the entire side portions up to the tip of theknob 14, but in order to facilitate bending deformation of theknob 14 and make it easy to pinch, theknob 24 as in this embodiment shown in FIG. 4 is used. It is better to extend from the part where thepart 14 is connected to thehinge part 13 to the vicinity of the center, that is, the vicinity of thefitting hole 22.
The present embodiment is the same as the first embodiment in other configurations, and the operational effects other than the operational effects of thevertical ribs 24 are the same as those of the first embodiment.

本発明の中栓付き容器は、口部に装着する中栓に引き出しやすい摘み部を設けて、中栓を取り外しやすくしているので、材質の異なる中栓を容器本体から容易に分別廃棄することができ、リサイクル用容器などに用いて好適である。
また、摘み部を容器の口部の凹溝内に確実に収容するようにしているので、蓋体を口部に係合する際に邪魔にならず、蓋体の係合によって損傷することもないため、蓋体を繰り返し着脱したり、使用時に中栓を取り外して噴射ポンプなどの他の注出具を取り付けるような容器にも、好適に利用できる。The container with an inner plug of the present invention is provided with a knob portion that can be easily pulled out on the inner plug to be attached to the mouth portion, so that the inner plug can be easily removed. It can be used for recycling containers and the like.
In addition, since the knob portion is securely accommodated in the concave groove of the mouth portion of the container, it does not get in the way when the lid body is engaged with the mouth portion, and may be damaged by the engagement of the lid body. Therefore, the container can be suitably used for a container in which the lid is repeatedly attached and detached, or the inner plug is removed during use and another dispensing tool such as an injection pump is attached.
