Description

【0001】
【発明の属する技術分野】
本願の発明は、各種の内容物を収容した広口の中空容器の開口部に密閉蓋を開閉自在に設けた収納容器に係わるもので、中でも、化粧用のクリームや白粉等を収容するのに適した中空容器の開口部を密閉する蓋体を、指先により簡単に開開できるようにした広口の密閉容器に関するものである。
【0002】
【従来の技術】
従来から着脱自在な蓋体を有する広口の密閉容器は、ジヤムやバターその他の液状食品を収容した食品容器、クリームや白粉等の化粧科を収容した化粧品容器、靴墨やワックス等を収容した日用品容器等に広く用いられてきた。
そして、このような広口の密封容器は、実公昭53−7941号や実公平7−23411号、特開平10−203547号公報に見られるように、ガラスや合成樹脂等で成形した中空容器の口頸部に、金属または合成樹脂やエボナイト等で形成されたネジ蓋や嵌合蓋を螺合または嵌合して密閉する形式のものが、一般に使用されてきた。
【0003】
上記のような密閉容器は、特別な道具を用いなくて蓋体を簡単に開封することができ、また、再び簡単に密閉することができて、非常に便利であることから多くの密封容器に使用されている。
しかし、一般に多用されているこのような容器は、容器本体の口頸部に所定のピッチで形成されたネジ山に対して、内周面に前記ネジ山と同一ピッチのネジが形成されたネジ蓋を螺合させるか、または、口頸部に形成された係合突起に係合する係合部を設けた蓋部を係止させることにより、容器の開口部を蓋体で密封するようにしたものであるから、蓋体の開閉がやや面倒であると共に、開封して容器から分離された蓋体が落下して汚れたり、紛失することがあった。
【0004】
また、上記した容器の口径が大きい容器の場合には、容器本体の口頸部のネジ山の先端部にネジ蓋の溝を噛み合わせて、ネジ蓋を容器本体の口頸部に正確に螺合させるには、ネジ蓋を半周以上にわたって慎重に回転させて螺合しなけれぱならない不便さもある。
そこで、このような不便さを解消して、もっと簡単に蓋体を開閉できるようにした密封容器として、図9に示すように、密閉蓋体24を容器本体22の口頸部23に開閉自在に連結した密閉容器21が知られれている。
【0005】
上記の密閉容器21は、広口の中空容器本体22の開口部を密閉するようにした蓋体24の一端を、容器の口頸部23に回動バネを有する蝶番25等により開閉自在に連結したものである。
そして、前記蓋体24は、図9に示すように、中空容器本体22の開口端に密着して密閉する円板状の天板24aと、該天板の周縁部に垂設されて容器本体の口頸部23の外周面に密着する円筒縁部24bと、該円筒縁部に突設されて口頸部の係合突起23aに係合して係止可能に形成された係止片26と、前記円形状の天板24aの周縁部の一端に設けて容器の口頸部23に連結する蝶番25とから形成されている。
【0006】
上記のような構成をした密閉容器21は、容器本体22の収容凹部にクリームや白粉等の化粧料を収容してから前記蓋体24を閉じると、天板24aの内面に設けられたパッキン27が容器本体22の口頸部23の開口端に密着して、前記円筒縁部24bが口頸部23の外周面に嵌合、密着して密閉すると共に、前記係止片26が口頸部23の外周面に設けられた係合突起23aに係止して、前記蓋体24は容器本体22の口頸部23に嵌合、固定される。
また、このようにして開口部が密閉された容器の蓋体を開いて使用するには、蓋体の前記係止片の先端部に手の指先を掛けて押し上げると、係止片は外側へ弾性変形して口頸部の係合突起との間の係合関係が解かれて、蓋体の円筒縁部が開口端から離れると、蓋体は蝶番のバネの復元力により上方へと開かれる。
【0007】
このように形成した密閉容器に於いては、容器の口頸部に蝶番を介して開閉自在に連結された蓋体は、開口部を密閉して係止片により口頸部に密閉、係止されていて、前記係止片を指先で押し上げることにより蓋体を簡単に開放することができて便利である。
しかし、前記蓋体は、係止片のみで口頸部に係止されて密閉状態に保持されるが、不用意に蓋体が開くことがないように係止するために、係止片自体が肉厚に形成されているので、前記蓋体を開くには係止片を押し上げて変形させなくてはならず、それには指先にやや大きな力を必要とするので、指先の力が弱い人にとっては開けにくい場合があるから、もう少し小さな力でも簡単に素早く蓋体を開けることができるような構造をした密閉容器が望まれる。
【0008】
【発明が解決しようとする課題】
本願の発明は、上記したような問題点を解決して、開閉自在な蓋体を有する密閉容器に於いて、中空容器本体の開口部に対して蓋体を容易に開閉することができて、密封性を維持することができるように創案したもので、中空容器の口頸部に蓋体を嵌着して密閉状態に保持するのに、蓋体をできるだけ簡単な構造に形成すると共に、できるだけ多くの中空容器に適用できるような構造にして、また、小さな指先の力だけで蓋体を簡単に素早く、且つ、スムーズに開開することができるように形成すると共に、中空容器の口頸部に嵌着された蓋体は、開封操作を行う時以外には、自然に開蓋されることがないように構成された密封容器を提供することを目的とする。
【0009】
【課題を解決するための手段】
本願の発明は、上記した目的を達成するために、中空容器の開口部に嵌着して密閉する蓋体を、喋番により口頸部に開閉白在に連結した密閉容器に於いて、前記蓋体を中空容器の開口端に密着する天板と、該天板の周縁部にして中空容器の口頸部に嵌合する円筒縁部とから密閉可能にすると共に、前記円筒縁部の端部に薄肉を介して係合片を突設して口頸部に係止可能にして密閉蓋を形成して、前記密閉蓋を蝶番を介して口頸部に開閉自在に連結して、更に、前記密閉蓋に対して前記天板と円筒縁部および係合片とを覆って密着可能に形成した押さえ蓋を設けると共に、該押さえ蓋を前記密閉蓋の蝶番に一体に連結して、前記密閉蓋と一緒に開閉可能にした密閉蓋体に形成して、中空容器の口頸部に開閉自在に連結した密閉蓋体を有する密閉容器を構成する。
【0010】
【発明の実施の形態】
本願発明の密閉容器は、クリームや白粉等の化粧料その他を収容可能な収容凹部を設けた中空容器を、合成樹脂やガラスその他により成形して、前記中空容器の口頸部の外周部に密閉蓋を開閉自在に連結する蝶番と、容器の開口部を密閉した密閉蓋を係止する係合突起とを設けて中空容器本体を形成する。
そして、前記中空容器本体の開口部を密閉して口頸部に嵌着可能に形成すると共に口頸部の係合突起に係止する係止片を形成した密閉蓋を、口頸部に蝶番を介して開閉自在に連結して密閉容器を形成すると共に、前記密閉蓋の外面を覆って密着するように形成した押さえ蓋を、前記密閉蓋と一体に蝶番により開閉可能に連結して、開閉自在な密閉蓋体を有する密閉容器を形成する。
【0011】
【実施例】
本願の発明について、一つの最適な実施例に基づいて、図面を参照しつつ、以下に説明する。
本願発明は、熱可塑性合成樹脂やガラス等を用いて、クリームや白粉等の化粧料、あるいは、その他のクリーム状物質等を収容可能な収容凹部を設けた中空の容器本体2を形成して、前記容器本体の口頸部3に容器の開口部を密閉する密閉蓋4を開閉自在に連結する蝶番5部分を形成すると共に、前記開口部を密閉した密閉蓋4を係止する係合突起3aを形成して、図1に示すような密閉容器1に於けるクリーム等を収容可能な中空容器本体2を形成する。
【0012】
そして、上記した中空容器本体2には、図2に示すように、開口部に密着して密閉する天板4aと口頸部に嵌合する筒状の嵌合壁4bと係合突起3aに係止する係止片6とからなる密閉蓋4を開閉可能に前記蝶番5に連結すると共に、前記密閉蓋4の上から天板4aと嵌合壁4bと係止片6を覆って密着するように形成した押さえ蓋8を被せて、前記密閉蓋4と一体に開閉可能に前記蝶番部5に連結して、簡単に開閉可能となした密閉蓋体9に形成することにより、図1および図2等に示したように、開閉自在な密閉蓋体を有する密閉容器1を形成する。
【0013】
上記したような中空の容器本体は、熱可塑性合成樹脂を射出成形することにより、クリームや白粉その他を収容可能にする中空の収容凹部と口頸部とを有する内壁部2aを形成すると共に、前記収容凹部の口頸部に段部を設けて内壁部を囲んで保護するように連設する外壁部2bを形成して、更に、前記口頸部3の一側部には密閉蓋体9が連結される蝶番部5を形成すると共に、前記蝶番と反対側には密閉蓋の係止片6が係合する係合突起3aを形成することにより、前記容器本体2の開口部を密閉する密閉蓋体9を開閉可能に蝶番連結して、前記密閉蓋体を密閉状態で口頸部に係止して固定可能に形成される。
【0014】
また、上記した開閉可能な密閉蓋4を形成するには、熱可塑性合成樹脂を射出成形して、図5に示すように、中空容器本体2の開口部に密着して密閉する円板状の天板部4aを形成すると共に、該天板の縁部に筒状の嵌合壁4bを周設して中空容器本体2の口頸部3に嵌着可能な蓋部を形成して、更に、前記嵌合壁の一端部に薄肉部6aを介して容易に変形可能な係止片6を突設して、前記口頸部の係合突起3aに係止可能に形成すると共に、前記係止片と反対側の前記蓋部の端部に連結部を突設して、中空容器本体2の口頸部3の蝶番に連結可能に形成することにより、中空容器本体2の口頸部3に開閉可能に連結する密閉蓋4を形成する。
【0015】
そして、前記密閉蓋4の外側に押さえ蓋8を被着して一体となした開閉白在な密閉蓋体9を形成するには、密閉蓋と同様に熱可塑性合成樹脂を射出成形して、図1または図2等に示すように、前記密閉蓋4の天板4aと嵌合壁4bと係止片6とを覆うようにして密着可能な平坦状の上壁部8aと筒状の周壁部8bとからなる押さえ蓋8を形成して、前記押さえ蓋の周壁部の一端部に前記密閉蓋と一体にして前記蝶番に連結可能な連結部を設けると共に、前記連結部とは反対側の周壁部に開閉用の指掛け片8cを設ける。
このようにして形成した押さえ蓋8は、内面に気密性のパッキン7等を設けた前記密閉蓋4に上から被せて密着せしめて一体にしてから、前記連結部4cを中空容器本体2の蝶番5部分に回動可能に連結して、開閉可能な密閉蓋体9に形成すると、図1に示したような開閉自在な密閉蓋体9を有する密閉容器1が構成される。
【0016】
上記のように構成された密閉容器1は、開閉自在な密閉蓋体9を開いた状態にして、容器本体2の収容凹部内にクリームや白粉等の化粧料を充填してから前記密閉蓋体を閉じると、図2に示すように、密閉蓋体9の内蓋である密閉蓋4に設けられたパッキン7が開口部の端面に密着すると共に、筒状の嵌合壁4bが口頸部3に嵌合して容器の開口部を密閉されるが、それと同時に、嵌合壁4bの端部に設けた係止片6が口頸部の係合突起3aに係止されて、前記密閉蓋4は密閉状態に固定される。
このようにして口頸部に固定された密閉蓋4は、密閉蓋体9の外蓋である押さえ蓋8により外周面が締めつけられて、押さえ蓋8の周壁部8bの内面に設けられた突起部8dが前記係止片6の簿肉の連結部6aに係合して、密開蓋4と押さえ蓋8からなる密開蓋体9は、容器本体2の口頸部3にきつく固定されて不用意に開蓋しないように保持する。
【0017】
上記のように容器本体2の口頸部3に固定された密閉蓋体9は、不用意に開くことはないが、使用するに際して前記密閉蓋体9を開く場合には、押さえ蓋8の周壁部に設けられた指掛け片8cに指先を掛けて押し上げると、図3に示すように、押さえ蓋8の突起部8dが密閉蓋4の係止片6の連結部から外れて、密閉蓋4の係止突起4dに係止して止まる。
そこで、更に押さえ蓋8を押し上げようとすると、密閉蓋4の係止片6は連結部6aが薄肉で変形し易く形成されているので、図4に示すように、押さえ蓋8の締めつけから解かれた係止片6は、外向きに変形して係止力が小さくなった状態になる。
【0018】
このようにして、押さえ蓋8の突起部8dが密閉蓋4の係止突起4dに係止して、弱い力でも押し上げ可能な状態になる密閉蓋4と押さえ蓋8からなる上記密閉蓋体9は、更に、図1に示すように、押さえ蓋8を押し上げることにより一緒に密閉蓋4が容器本体2の口頸部3から簡単に外れるので、本願の密開蓋体9は容易に開くことが可能である。
上記のようにして密閉蓋体9が開いた密閉容器1から内容物を取り出して使用した後に、再び密閉蓋体9を閉じると、密閉用のパッキンや密封材7が開口端に密着されると共に係止片6は係合突起3aに係止されて密閉状態になると同時に、係止片6はその上から押さえ蓋8の周壁部8dにより締めつけられて不用意に開蓋しない状態に保持される。
【0019】
上記した実施例に於ける本願発明の開閉自在な密閉蓋体9を有する密閉容器1は、中空容器本体1の開口部を密閉する密閉蓄4を、口頸部に蝶番により連結して開閉自在にすると共に、該密閉蓋に係止片6を設けて口頸部3に係止して固定するようにしたものに於いて、日頸部3に係止する前記密閉蓋4に押さえ蓋8を被着して係止片6を締めつけるようにして密開蓋体9を構成して、該密開蓋体9が不用意には開かないようにしたものであり、また、係止片6を締めつける押さえ蓋8を、図1や図2に示すように、密閉蓋4の周縁部のみを締めつけるようにした環状体に近似したものとなしたが、本願発明はこのような構造をしたものに限定されたものではない。
例えば、外蓋である押さえ蓋を、中蓋の天板面に密接するような形状にして、中蓋の全面を締め付けるようにしたり、あるいは、前記した実施例に於ける中蓋である密開蓋4について、図5(b)に示すように、複数個の係止片6を設けた形状にしたものを用いることにより、更に密閉性を強くした密閉容器に形成することができる。
【0020】
上記したのとは別の実施例として、例えば、熱可塑性合成樹脂を射出成形して、図6に示すように、クリーム等を収容する内壁部12aと、前記収容凹部の口頸部13に段部を設けて連設する外壁部12bとからなる中空容器を形成すると共に、前記口頸部の外周面に内蓋である密閉蓋14の係止片16が係合する係合突起13aを形成して、各種の内容物を収容して蓋体により密閉する密閉容器の容器本体12を形成する。
また、前記したパッキンや密封材に代えてアルミ箔等の気密性の密封シート材を用いて密封することもできる。
【0021】
また、同様に熱可塑性合成樹脂の射出成形により、前記容器本体12の口頸部13に嵌合可能な密閉蓋14に成形して、該密閉蓋の天板14aの周縁部に垂設した嵌合壁14bの下端部に薄肉の連結部を介して口頸部13の係合突起13aに係合する係止片16を複数個設けて係止可能に形成すると共に、天板14aの周縁部に立設した筒状壁14cの外周に外蓋18を螺着するネジ14dを形成して、図6に示すような口頸部13に固定可能な密閉蓋14を形成する。
同じく熱可塑性合成樹脂を射出成形して、前記密閉蓋に被着可能な外蓋18を形成して、該外蓋の円筒部18aの内周面にネジ18bを設けて前記密閉蓋の筒状壁14cに螺着可能に形成して、前記密閉蓋14に被着して一体となして、図8に示すような容器本体12の口頸部に着脱可能な密閉蓋体19を構成する。
【0022】
上記のように形成した密閉容器の容器本体12にクリーム等の内容物を収容してから、図8に示すように、容器本体の口頸部13に前記密開蓋体19を嵌合させて、図7に示すように、密閉蓋14の係止片16を口頸部の係合突起13aに係止させてから外蓋18を回動すると、密開蓋14は係止片16が口頬部に設けられた回り止めリブに係止して回動不能となり、図6に示すように、外蓋18だけが回動して下降して、前記密閉蓋の係止片16を外から締めつける結果、密閉蓋体19は不用意には開蓋しないように固定された密閉容器11が構成される。
【0023】
このような構成をした密閉容器11を使用するには、図6に示す密閉蓋体19を開放する方向に回動させると、外蓋18のみが回動して上昇する結果、図7に示すように、締めつけられていた係止片16は、開放されて変形可能な状態になる。
そこで、外蓋18を掴んで密閉蓋体19を引き上げると、外蓋の内面に設けられた係止片18cが密閉蓋14の上面部に設けた筒状壁14cの内周面に設けた係合部14eに係合して、密閉蓋14は上方へ移動する結果、図8に示すように、密閉蓋の係止片16は簡単に外側へ開くように変形して口頸部13の係合突起13aから外れるので、密閉蓋体19は容易に容器の口頸部13から取り外すことができて、内容物を使用することが可能になる。
【0024】
【発明の効果】
以上述べたように、本願発明は、密開容器の口頸部に開開自在な密開蓋を嵌着して開口部を密閉する手段として、従来の開口部を密閉する密閉蓋の上に押さえ蓋である外蓋を被せて、中蓋である前記密閉蓋を口頸部に対して締めつけるような構造にして、密閉蓋の開閉を行うための係止片を容易に変形させることができる構造にしても、不用意に密閉蓋が開くことがなくて、密閉蓋の開閉を簡単に操作することが可能になった。

BACKGROUND OF THE INVENTION
The invention of the present application relates to a storage container provided with a hermetic lid that can be opened and closed at the opening of a wide-mouthed hollow container containing various contents, and is particularly suitable for storing cosmetic cream, white powder, etc. Further, the present invention relates to a wide-mouthed sealed container in which a lid for sealing an opening of a hollow container can be easily opened by a fingertip.
[0002]
[Prior art]
Conventionally, a wide-mouthed sealed container with a detachable lid is a food container containing jam, butter and other liquid foods, a cosmetic container containing cosmetics such as cream and white powder, and a daily necessities container containing shoes, wax, etc. Have been widely used.
Such a wide-mouthed sealed container has a mouth of a hollow container formed of glass or synthetic resin, as seen in Japanese Utility Model Publication No. 53-7941, Japanese Utility Model Publication No. 7-23411, and Japanese Patent Application Laid-Open No. 10-203547. In general, a screw lid or a fitting lid formed of metal, synthetic resin, ebonite, or the like is screwed or fitted to the neck to seal the neck.
[0003]
Such a closed container can be easily opened without using a special tool, and can be easily sealed again. in use.
However, such a container, which is commonly used, is a screw in which a screw having the same pitch as that of the screw thread is formed on the inner peripheral surface of the screw thread formed at a predetermined pitch on the mouth and neck of the container body. The lid of the container is sealed with the lid by screwing the lid or by locking the lid provided with the engaging portion that engages with the engaging protrusion formed on the mouth and neck. Therefore, the opening and closing of the lid body is somewhat troublesome, and the lid body opened and separated from the container may fall and become dirty or lost.
[0004]
In the case of a container having a large diameter as described above, the screw lid groove is engaged with the tip of the thread of the mouth and neck portion of the container body, and the screw lid is accurately screwed to the mouth and neck portion of the container body. In order to match, there is also the inconvenience that the screw lid must be carefully rotated over half a circumference and screwed together.
Therefore, as shown in FIG. 9, the sealed lid 24 can be freely opened and closed to the mouth-neck portion 23 of the container body 22 as a sealed container that eliminates such inconvenience and makes it easier to open and close the lid. An airtight container 21 connected to is known.
[0005]
In the above-described sealed container 21, one end of a lid body 24 that seals the opening of a wide-mouthed hollow container body 22 is connected to the mouth-and-neck part 23 of the container by a hinge 25 having a rotating spring so as to be freely opened and closed. Is.
As shown in FIG. 9, the lid body 24 is provided with a disc-shaped top plate 24 a that is in close contact with the open end of the hollow container body 22 and hermetically sealed, and is suspended from the peripheral edge of the top board. A cylindrical edge 24b that is in close contact with the outer peripheral surface of the mouth-and-neck portion 23, and a locking piece 26 that is provided on the cylindrical edge portion so as to be engaged with and engageable with the engaging projection 23a of the mouth-and-neck portion. And a hinge 25 provided at one end of the peripheral edge of the circular top plate 24a and connected to the mouth / neck portion 23 of the container.
[0006]
The sealed container 21 configured as described above has a packing 27 provided on the inner surface of the top plate 24a when the lid 24 is closed after the cosmetic such as cream or white powder is accommodated in the accommodating recess of the container body 22. Is closely attached to the open end of the mouth-and-neck portion 23 of the container body 22, and the cylindrical edge portion 24b is fitted and tightly sealed to the outer peripheral surface of the mouth-and-neck portion 23. The lid 24 is engaged with and fixed to the mouth-and-neck portion 23 of the container body 22 by being engaged with an engagement protrusion 23 a provided on the outer peripheral surface of the container 23.
In addition, in order to open and use the lid of the container whose opening is sealed in this manner, when the fingertip is put on the tip of the locking piece of the lid and pushed up, the locking piece is moved outward. When the engagement relationship with the engagement projection of the mouth and neck is released due to elastic deformation and the cylindrical edge of the lid is separated from the open end, the lid opens upward by the restoring force of the hinge spring It is.
[0007]
In the sealed container formed in this way, the lid connected to the mouth and neck of the container through a hinge is opened and closed, and the opening is sealed and sealed to the mouth and neck by a locking piece. It is convenient that the lid can be easily opened by pushing up the locking piece with a fingertip.
However, the lid body is locked to the mouth and neck by only the locking piece and is kept in a sealed state. However, in order to lock the lid body so that it does not open carelessly, the locking piece itself Since it is formed thick, it must be deformed by pushing up the locking piece to open the lid, and this requires a slightly large force on the fingertip. Therefore, an airtight container having a structure that can easily and quickly open the lid with a little less force is desired.
[0008]
[Problems to be solved by the invention]
The invention of the present application solves the problems as described above, and in a closed container having an openable / closable lid, the lid can be easily opened and closed with respect to the opening of the hollow container body. It was created so that the sealing performance can be maintained. In order to hold the lid on the mouth and neck of the hollow container and keep it sealed, the lid is formed as simple as possible, and as much as possible. The structure can be applied to many hollow containers, and the lid can be easily and quickly opened with a small fingertip force. It is an object of the present invention to provide a sealed container that is configured so that the lid body fitted to is not naturally opened except when the opening operation is performed.
[0009]
