Description

【０００１】
【発明の属する技術分野】
本願の発明は、液状の化粧料やシャンプーその他の溶液を収容する液体注出容器に係わるもので、特に、ガラスや合成樹脂等で成形された壜形その他の中空の容器本体の肩部に、異質または異色の成形品からなる肩カバーを被せて、製品の外観上の見栄えを良くしたり、容器本体の肩部の保護や使い勝手を良くしたりすると共に、前記肩カバーを簡単に分離可能にした、肩カバー付きの液体注出容器に関するものである。
【０００２】
【従来の技術】
一般に広く用いられている液体を収容した中空容器、中でも化粧水等を収容したガラスの中空容器は、容器本体とは異なる合成樹脂その他の材質からなる装飾部品が容器本体の口頸部もしくは肩部に取り付けられて、容器の外観上の見栄えを良くして、容器の美的効果を高めることにより、内容物に高級感を抱かせるようにした液体収容容器が用いられることがある。
そして、これらの従来品に於いては、移送中や使用中には装飾部品が容器本体に確実に保持された状態にあることが必要であることから、装飾部品は流通段階や使用期間中は不用意に外れることがないように、接着剤その他によりきつく固定されていた。
【０００３】
ところが、最近になって各種の廃棄物の処理が社会的に大きな問題となってきたことから、使用済みとなったこれらの空の容器は、資源として回収して再利用することが求められるようになった結果、空になった容器を廃棄する際には、容器を材料の種類別ごとに分別してから廃棄することが必要になってきた。
【０００４】
そこで、従来から用いられてきた容器に於ける装飾部材の固定方法を改良して、ドライバーや硬貨を用いて容器の肩部から装飾部品を簡単に分離できるようにしたものが、特開平９−６６９４１号公報やその他に記載されている。
これらの液体収容容器は、図７に示すように、ガラスからなる容器本体２１の口頸部２１ａに蓋体を螺合するネジ部２１ｂが設けられると共に、容器本体の肩部２１ｃに前記口頸部を囲むように楕円形の段部２１ｄが形成されていて、該肩部の段部に装飾用の肩カバー２２を着脱可能に嵌合して保持したものである。
【０００５】
前記肩カバー２２は、裏面に円弧状に複数の弾性片２２ａが突設されていて、該弾性片の下端寄りに突設された凸部２２ｂを容器本体の肩部２１ｃに設けた凹溝状の段部２１ｄに係合させて、肩カバー２２を容器本体２１の肩部２２に取り付けられている。
そして、空になった容器を廃棄する際には、図８に示すように、前記肩カバー２２に設けられた凹み２２ｃに硬貨２３を差し込んで、容器本体２１に対して肩カバーをこじることにより、肩カバー２２を容器本体２１から分離して、容器本体とは別にして廃棄される。
【０００６】
しかし、このような容器に於いては、肩カバーを外すには凹みに挿入可能なドライバーや硬貨等が必要であり、必ずしも簡単に容器本体から外せるとは言えないし、また、肩カバーには、容器本体との間に硬貨等を差し込みできるだけの凹みを設けておかなければならず、化粧容器等にとっては外観を悪くするという問題があり、更には、肩カバーの形状が複雑な場合には、それを成形するには高い寸法精度と成形技術が必要となる。
【０００７】
そこで、上記したような問題点を改善して、容器本体とは異質の装着部品である肩カバー等を簡単に取り外すことができるようにして、分別回収が容易に行えるようにすると共に、肩カバー等の構造が簡単で、高度の成形技術を必要としないようにして、従来のものに比べて製造コストを低減できるようにしたものが、特開２０００−１０９０７４号に提案されている。
【０００８】
上記発明の液体収容容器は、化粧料等の溶液が収容された容器に被着する肩カバー３２を、図１１に示すように、容器本体３１の口頸部３１ａを挿通可能する開口部３２ａを設けて環状に形成して、前記肩カバー３２を図９に示すように容器本体の肩部３１ｂに載置して、その上から吸込み管が設けられた吐出具（注出ポンプ）３３を容器本体３１の口頸部３１ａ内に挿入せしめて、吐出具の筒状部３３ａのねじ溝に口頸部３１ａのねじ山に螺合して固定したものである。
【０００９】
上記のように形成された液体収容容器は、図１０に示したように、吐出具３３の筒状部３３ａの下端が環状の肩カバー３２に設けられた弾性片３２ａに当接して、肩カバー３２は弾性片の弾性力により一定圧力で容器本体３１の肩部３１ｂに圧接して保持されていて、更に、前記吐出具３３の筒状部３３ａを覆うように化粧カバー３５を被着して固定されており、不使用時には、前記吐出具３３の上からキャップ３４を被せると、キャップの下端端が肩カバー３２の円筒部に嵌合して噴射ヘッド３３ｂを作動不能に構成される。
【００１０】
上記のように構成された液体注出容器は、空になった容器を廃棄する際には、容器本体の口頸部に螺合した吐出具を緩めて取り外すことにより、吐出具で押さえられていた肩カバーを容器本体から簡単に外すことができるので、肩カバーを容器本体から分別して廃棄することが可能である。
しかし、上記した液体注出容器に於ける肩カバーは、容器本体の口頸部に挿着する環状体の下方にスカート部を垂設すると共に、上方に吐出具の筒状部に嵌合する筒部を突設して、更に、前記筒部の内周面に弾性片を設けて容器本体の肩部に保持するように形成したものであるから、その構造はやや複雑なものとなり、注出具を容器の口頸部に螺合せしめた筒状部により圧接して保持するようにしたものであるから、容器の口頸部に螺合する吐出具を用いる液体容器には適しているが、それ以外の一般的な液体容器に用いるのには適していない。
【００１１】
【発明が解決しようとする課題】
本願の発明は、上記のような問題点を解決して、ガラス等からなる中空容器の肩部に異質の装飾部材を被着して、前記容器に美的効果を持たせたり、内容物に対して高級感を抱かせたりするための肩カバーを、注出具を備えた液体収容容器に対して被着できるだけでなく、各種の溶液を収容した注出具を用いない一般的な中空容器に対しても適用できるように形成する。
そして、前記肩カバーは、その成形加工が容易に行えるようにできるだけ簡単な構造に形成して、その製造コストを低減できるようにすると共に、容器本体に対して簡単に着脱できるように形成して、空になった液体収容容器を廃棄する際に、容器本体から前記肩カバーを簡単に分離できるようにして、分別回収された容器を再利用できるようにした液体収容容器を提供する。
【００１２】
【課題を解決するための手段】
上記した課題を解決するために、本願発明は、溶液を収容する中空容器の肩部に装着する肩カバーを、容器本体とは異質の材料を用いて容器本体の口頸部に挿着可能な筒状体を形成すると共に、前記筒状体の下端部には容器本体の肩部に当接して係合する固定部を設け、また、筒状体の上端部には容器本体の口頸部に螺着される蓋体が係合して保持する保持部を設けて、容器本体の口頸部に挿着せしめて肩部に被着可能に形成する。
そして、前記のように形成した肩カバーを、溶液を収容した容器本体の肩部に被着せしめて、容器の口頸部に螺着する蓋体により固定する。
【００１３】
【発明の実施の形態】
本願発明の肩カバーは、各種の溶液を収容可能な中空容器の本体部分とは異なる材質からなる合成樹脂を射出成形して、容器本体１の口頸部１ａに挿着可能な筒状体５ａを形成すると同時に、該筒状体の下端部に容器本体の肩面１ｂに密着する円筒部と肩部の係合凸部に係合する係合凹部を設けた円筒部とからなる固定部５ｃを形成し、また、該筒状体の上端部に容器本体の口頸部１ａに螺着された蓋体３と係合する係合段部を設けた保持部５ｂを形成して、溶液を収容した容器本体１の口頸部に挿着せしめて肩部１ｂに被着可能な肩カバー５を形成する。
【００１４】
上記のように形成した肩カバー５を、溶液を収容した中空容器１の口頸部１ａを挿通して肩部１ｂに被着せしめて、前記筒状体の下端部に設けた固定部５ｃの円筒部の端面を容器本体の肩面に密着せしめると共に円筒部の一部に設けた係合凹部５ｅを肩部の係合凸部１ｃに係合せしめて、容器本体１の肩部１ｂに立設した後に、容器本体の口頸部１ａに注出装置を装着して蓋体３を螺合せしめて固定すると、該蓋体の螺合筒部３ａが前記肩カバーの筒状体の上端部に設けられた保持部５ｂの係合段部５ｄに係合して、肩カバーは下方へ押圧されて容器本体の肩部に密着して固定されて、肩カバーが装着された液体収容容器が構成される。
【００１５】
【実施例】
以下に、本願発明の中空容器の肩カバーとそれを装着した液体収容容器について、一つの最適な実施例に基づいて、図面を参照しつつ詳細に説明する。
本願発明は、図１に示したように、内溶液を収容した中空の容器本体１の口頸部１ａに、押圧ヘッド２ａと噴射ノズル２ｂからなる噴射ヘッド２と、螺合筒部３ａを設けた蓋体３とを備えた縦型の往復動式の注出ポンプからなる注出装置４を螺着すると共に、前記容器本体１の肩部１ｂに肩カバー５を装着して、内容液を注出可能にした液体注出容器である。
【００１６】
上記肩カバー５は、容器本体１とは異質の熱可塑性合成樹脂を用いて射出成形して、図２に示すように、中空の容器本体の口頸部１ａが挿通されて肩部１ｂに装着可能な筒状体５ａを成形して、前記筒状体の下端部には容器本体の肩部１ｂに密着して肩部の係合凸部１ｃに係合する係合凹部５ｅを設けた固定部５ｃを形成すると共に、前記筒状体の上端部には容器本体の口頸部１ａに螺着される蓋体３と係合する係合段部５ｄを設けた保持部５ｂを形成して、前記肩カバー５は容器本体１の口頸部１ａを挿通した肩部１ｂに被着可能に成形する。
【００１７】
尚、図２に於いて、肩部の係合凸部１ｃと肩カバーの係合凹部５ｅは両側面に現れて、周方向に連続しているように見えるが、連続状にもうける必要はなくて、図１を参照すればわかるように、前記係合凸部１ｃを周方向に適当な間隔を空けて間欠的に複数個を設けて、それに対応して係合凹部５ｅを設けた突起壁５ｆを形成することも可能であるから、容器の大きさや形状に合わせて一つ又は幾つかの係合凹凸部を設けるかを決めることができる。
【００１８】
上記のように成形された肩カバー５は、図２に示したように、溶液を収容した円筒状をした中空容器の口頸部１ａを筒状体に挿通して肩部１ｂに被着せしめて、前記筒状体５ａの下端部に設けた固定部５ｃの係合凹部５ｅを容器本体１の肩部の係合凸部１ｃに係合せしめて、肩カバー５を容器本体１の肩部１ｂに立設した状態にしておいて、容器本体１の口頸部１ａに注出装置４を装着して蓋体３を螺合せしめて固定すると、前記蓋体の螺合筒部３ａの段部３ｂが前記肩カバー５の筒状体の上端部に設けられた保持部５ｂの係合段部５ｄに係合して、肩カバー５を下方に押圧して容器本体１の肩部１ｂに固定せしめて、図示したように肩カバー５が装着された液体収容容器に構成される。
【００１９】
また、上記した例に於いて、肩カバー５の保持部５ｂに係合段部５ｄを設けておいて、蓋体の螺合筒部３ａの段部３ｂを係合せしめて、蓋体により肩カバーを押圧して、密着固定するようにしたが、必ずしもこのように固定するものに限定されるものではなくて、係合段部で肩カバーが押圧、固定されずに、蓋体との間に隙間を設けた状態にして、肩カバーを容器の肩部との凹凸部の係合のみで固定できるようにすることも可能である。
【００２０】
上記した実施例は、胴壁部分が円形状の筒体に形成された容器本体の肩部に円筒状に形成した肩カバーを被着して固定した液体収容容器であったが、本願発明の肩カバーは、このような円筒状をした容器に適用することに限定されるものではなくて、図３に示すように、容器本体の胴壁部分の断面が楕円形状をした筒状体に形成されたものであっても、簡単に装着することができる。
また、上記実施例に於いては、蓋体と肩カバーとを係合させるのに、蓋体の下端部と肩カバーの上端部の係合面を段状に形成して、双方の端面が係合するようにしたが、本願発明は、必ずしも、係合面を段状に形成する必要はなくて、蓋体と肩カバーとのどちらか一方に段部を設けて係合可能にして肩カバーを押圧、固定可能にするか、あるいは、両方とも段部を設けずに、それぞれの端面を当接せしめて肩カバーを押圧して、容器の肩部に固定するようにしてもよい。
【００２１】
図３（ｂ）に示された液体注出容器は、胴壁部分が楕円形状をした筒状に形成された容器本体１１の肩部１１ｂに肩カバー１５を被着せしめると共に、上下方向に往復動せしめる縦型の注出ポンプからなる注出装置４を口頸部１１ａに螺着せしめたものである。
前記楕円形状をした容器本体１１に被着された肩カバー１５は、図３（ａ）に示されるように、容器本体の楕円形状に合わせて下端部は楕円形状にして、また、上端部は蓋体が係合可能な円形状をした複合形の筒状体に形成されている。
【００２２】
そして、上記のように形成された肩カバー１５は、図４に示したように、筒状体の短径方向側の筒状壁１５ｇには、前記した円筒状の実施例の場合と同じように上端の頂壁部に傾斜面が設けられずに、筒状壁の下端部には容器本体１１の肩部の係合凸部１１ｃに係合する係合凹部１５ｅが設けられて係止可能に形成されていて、また、筒状体の長径方向側の筒状壁１５ｈには、上端の頂壁部に傾斜面１５ｃが設けられると共に、下端部は容器本体１１の肩部１１ｂの上壁面に密接するように形成されていて、筒状体の上端部には蓋体３の螺合筒部３ａの係合部が係合する保持部１５ｂが形成されている。
【００２３】
上記のように形成された肩カバー１５は、図４に示すよう、溶液が収容された楕円形状をした容器本体１１の口頸部１１ａを挿通せしめて肩部１１ｂに被着して、前記筒状体の長径方向側の筒状壁１５ｈを肩部１１ｂの上壁面に密着せしめると同時に、前記筒状体の短径方向側の筒状壁１５ｇの下端部に設けた係合凹部１５ｅを容器本体１１の肩部の係合凸部１１ｃに係合せしめて、肩カバー１５を容前記肩部１１ｂに立設した状態で容器本体１１の口頸部１１ａに注出装置４を装着して蓋体３を螺合せしめて固定すると、前記蓋体の螺合筒部３ａの段部３ｂが前記肩カバー１５の筒状体の上端部に設けられた保持部１５ｂに係合して、肩カバー１５は容器本体１１の肩部１１ｂに押圧、固定されて、その上に保護キャップを被せて、図３（ｂ）に示したように肩カバーが装着された液体収容容器が構成される。
【００２４】
上記のように構成された液体収容容器は使用するに際して、保護キャップ６を外してから注出装置４の押圧ヘッド２ａを押し下げることにより内溶液を注出することができる。
このようにして内溶液が空になった容器は廃棄する際に、図５に示すように、注出装置の蓋体３を螺脱せしめて、容器本体の口頸部１ａから注出装置４を上方へ引き抜いてから、肩カバー５を掴んで係合凹部５ｅが設けられた側へこじってやることにより、容器本体１から肩カバー５を簡単に分離することができるので、分別して廃棄することが可能である。
【００２５】
上記した実施例に於いては、いずれの容器も、肩カバーの下端の固定部の係合凹部を容器本体の肩部に設けた係合凸部に係止して、容器本体の口頸部に注出装置を装着した蓋体を螺合せしめて、前記蓋体により肩カバーを押圧、保持して肩部に固定した液体収容容器であったが、本願発明は、必ずしも、このように注出装置を装着したものに限ることなしに、注出装置を用いない容器本体についても肩カバーを固定した液体収容容器を構成することが可能である。
【００２６】
例えば、図６に示すように、本願発明の筒状体からなる肩カバー５を、溶液を収容してなる円筒状の容器本体１の口頸部１ａに挿通せしめて肩部１ｂに被着すると共に、筒状体５ａの下端部に設けた固定部５ｃの係合凹部５ｅを容器本体の肩部の係合凸部１ｃに係合して肩部１ｂに立設せしめてから、容器本体１の口頸部１ａに開閉可能なヒンジ蓋１３ｃを設けた蓋体１３を螺合せしめて、前記蓋体の螺合筒部１３ａの係合部１３ｂを肩カバー５の筒状体の上端の保持部５ｂに係合せしめて押圧して、肩カバー５を容器本体１の肩部１ｂに固定せしめて液体収容容器を構成することができる。
【００２７】
本願の発明に使用される肩カバーは、容器本体とは異質の材質を用いて容器の口頸部に挿着可能に形成されたもので、例えば、容器本体がガラスからなる場合には、それに被着する肩カバーは色々な色彩に着色できて、成形が容易である熱可塑性合成樹脂を用いて射出成形により成形して、また、容器本体がポリエチレンテレフタレート（ＰＥＴ）樹脂等の高級樹脂で形成されている場合には、肩カバーをポリエチレン（ＰＥ）やポリプロピレン（ＰＰ）等の汎用樹脂により射出成形したものが用いられている。
【００２８】
【発明の効果】
以上、説明したように、本願の発明は、容器本体の肩部に装着する肩カバーを、容器の口頸部を挿通して肩部に被着可能な筒状体に形成して、口頸部に螺着する蓋体により肩部に押圧、固定するように構成したので、肩カバーは簡単な筒状体からなっており、その成形が簡単であることから製造コストを低減させることができて、また、蓋体を螺着または嵌着することができるようにした口頸部を備えた円筒状の容器であれば、簡単に装着することができる。
そして、本願発明の肩カバーが装着された液体容器は、空になって廃棄する際には、容器本体の口頸部に螺着または嵌着された蓋体を外すことにより、蓋カバーを簡単に分離することができるので、容器の分別回収の処理を容易に行うことが可能である。

BACKGROUND OF THE INVENTION
The invention of the present application relates to a liquid dispensing container for storing liquid cosmetics, shampoos and other solutions, and in particular, on the shoulder of a bowl-shaped or other hollow container body formed of glass or synthetic resin, Cover the shoulder cover made of molded products of different or different colors to improve the appearance of the product, protect the shoulder of the container body and improve usability, and make the shoulder cover easily separable The present invention relates to a liquid dispensing container with a shoulder cover.
[0002]
[Prior art]
Generally used hollow containers containing liquids, especially glass hollow containers containing lotion, etc., decorative parts made of synthetic resin or other materials different from the container body are the neck or shoulder of the container body. In some cases, a liquid storage container is used that enhances the appearance of the container and enhances the aesthetic effect of the container to enhance the contents of the container.
In these conventional products, it is necessary that the decorative part is securely held in the container body during transfer or use. It was firmly fixed with an adhesive or the like so as not to come off carelessly.
[0003]
However, since the disposal of various types of waste has become a major social problem recently, these used empty containers are required to be collected and reused as resources. As a result, when disposing of an empty container, it has become necessary to dispose of the container after separating the container according to the type of material.
[0004]
Therefore, a method for fixing a decorative member in a conventionally used container has been improved so that a decorative part can be easily separated from the shoulder of the container using a screwdriver or a coin. 66941 and others.
As shown in FIG. 7, these liquid storage containers are provided with a screw portion 21b for screwing a lid to a mouth / neck portion 21a of a container body 21 made of glass, and at the shoulder portion 21c of the container body, the mouth / neck portion. An elliptical step portion 21d is formed so as to surround the portion, and a shoulder cover 22 for decoration is detachably fitted and held on the step portion of the shoulder portion.
[0005]
The shoulder cover 22 has a plurality of elastic pieces 22a projecting in an arc shape on the back surface, and a convex groove 22b projecting near the lower end of the elastic piece has a concave groove shape provided on the shoulder portion 21c of the container body. The shoulder cover 22 is attached to the shoulder portion 22 of the container body 21 by being engaged with the step portion 21d.
Then, when discarding the empty container, as shown in FIG. 8, the coin 23 is inserted into the recess 22 c provided in the shoulder cover 22, and the shoulder cover is twisted against the container body 21. The shoulder cover 22 is separated from the container body 21 and discarded separately from the container body.
[0006]
However, in such a container, in order to remove the shoulder cover, a screwdriver or a coin that can be inserted into the recess is necessary, and it cannot be said that it can be easily removed from the container body. There must be a dent enough to insert coins etc. between the container body, there is a problem that the appearance of the cosmetic container etc. deteriorates, and furthermore, when the shape of the shoulder cover is complicated, Molding it requires high dimensional accuracy and molding technology.
[0007]
Therefore, by improving the above-described problems, the shoulder cover, which is a different mounting part from the container body, can be easily removed, so that the separate collection can be easily performed, and the shoulder cover Japanese Patent Laid-Open No. 2000-109074 proposes a structure that has a simple structure and does not require a high-level molding technique and can reduce the manufacturing cost compared to the conventional one.
[0008]
The liquid container of the present invention has an opening 32a through which the shoulder cover 32 to be attached to a container containing a solution such as cosmetics can be inserted, as shown in FIG. As shown in FIG. 9, the shoulder cover 32 is placed on the shoulder 31b of the container body, and a discharge tool (pumping pump) 33 provided with a suction pipe is provided on the container. It is inserted into the mouth / neck portion 31a of the main body 31, and screwed into the screw groove of the mouth / neck portion 31a in the screw groove of the tubular portion 33a of the discharge tool and fixed.
[0009]
As shown in FIG. 10, the liquid container formed as described above is in contact with the elastic piece 32 a provided on the annular shoulder cover 32 at the lower end of the cylindrical portion 33 a of the discharge tool 33, 32 is held in pressure contact with the shoulder 31b of the container body 31 with a certain pressure by the elastic force of the elastic piece, and further, a decorative cover 35 is attached so as to cover the tubular portion 33a of the discharge tool 33. When not in use, when the cap 34 is put on the discharge tool 33, the lower end of the cap fits into the cylindrical portion of the shoulder cover 32, and the ejection head 33b is configured to be inoperable.
[0010]
When discarding an empty container, the liquid dispensing container configured as described above is held down by the discharge tool by loosening and removing the discharge tool screwed into the mouth and neck of the container body. Since the shoulder cover can be easily removed from the container body, the shoulder cover can be separated from the container body and discarded.
However, the shoulder cover in the liquid dispensing container described above has a skirt portion suspended below the annular body to be inserted into the mouth and neck portion of the container body, and is fitted to the tubular portion of the discharge tool upward. Since the cylindrical portion is provided so as to be further provided with an elastic piece on the inner peripheral surface of the cylindrical portion and held on the shoulder portion of the container body, the structure becomes somewhat complicated. Since the ejector is held in pressure contact with a cylindrical portion screwed into the mouth and neck of the container, it is suitable for a liquid container using a discharge tool that is screwed into the mouth and neck of the container. It is not suitable for use in other general liquid containers.
[0011]
[Problems to be solved by the invention]
The invention of the present application solves the above-mentioned problems, and attaches a foreign decorative member to the shoulder portion of a hollow container made of glass or the like to give the container an aesthetic effect or to the contents. In addition to being able to attach a shoulder cover to give a sense of quality to a liquid container equipped with a pouring tool, it also applies to a general hollow container that does not use a pouring tool containing various solutions. Is also formed so as to be applicable.
The shoulder cover is formed as simple as possible so that the molding process can be easily performed, so that the manufacturing cost can be reduced, and the shoulder cover can be easily attached to and detached from the container body. When the empty liquid container is discarded, the liquid container is provided so that the shoulder cover can be easily separated from the container body, and the separately collected container can be reused.
[0012]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention can insert a shoulder cover attached to a shoulder portion of a hollow container containing a solution into a mouth and neck portion of a container body using a material different from the container body. A cylindrical body is formed, and a lower end portion of the cylindrical body is provided with a fixing portion that comes into contact with and engages with a shoulder portion of the container body. A holding part that engages and holds the lid body that is screwed onto the container is provided, and is inserted into the mouth-neck part of the container body so as to be attachable to the shoulder part.
Then, the shoulder cover formed as described above is attached to the shoulder of the container main body containing the solution, and is fixed by a lid that is screwed to the mouth and neck of the container.
[0013]
