Description

【0001】
【発明の属する技術分野】
本発明は、容器本体と蓋体とを開閉回動自在に結合した容器の蝶番構造に関し、容器本体と蓋体とを結合した蝶番軸に加わる剪断力を阻止する蝶番構造に関する。
【0002】
【従来の技術】
化粧用コンパクト容器として、容器本体の後端部に設けた軸孔を穿設した蝶番片と、同様に蓋体の後端部に設けた軸孔を穿設した蝶番片とを組合せ、各軸孔に蝶番軸を挿通し、容器本体に対して蓋体を開閉回動自在に結合したものが知られている。
【0003】
化粧料コンパクト容器は、蝶番軸を回動軸として、容器本体に対して蓋体を回動した状態で、容器本体若しくは蓋体の一方に何らかの強い外力が加わると、その外力の作用により、外力が加わった容器本体若しくは蓋体の位置がずれようとし、容器本体の蝶番片に穿設された軸孔と蓋体の蝶番片に穿設された軸孔とに跨った蝶番軸の部分に集中的に大きな剪断力が働いて、蝶番軸が破壊されやすい。
【0004】
特に、容器本体に対する開方向への蓋体の回動限において、容器本体若しくは蓋体の開回動方向に何らかの外力が加わると、外力が加わった部分が力点となり、容器本体の後端に蓋体が突き当たった部分を支点として、蝶番軸が力点に対する作用点となって、蝶番軸にてこの作用による大きな剪断力が働き、蝶番軸を破壊することがあった。
【0005】
このため、従来においては、容器本体及び蓋体を結合する蝶番軸として、機械的強度の強い、金属製の蝶番軸を用いていた。
【0006】
一方、近年においては、容器本体と蓋体と蝶番軸とを同一素材として分別回収する煩雑さを回避すること、容器を軽量化できること、製造コストが安価であることと等の利点を考慮して、化粧用コンパクト容器に合成樹脂製の蝶番軸が多く用いられている。
【0007】
【発明が解決しようとする課題】
しかしながら、近年において、化粧用コンパクト容器に多用される合成樹脂製の蝶番軸は、金属製の蝶番軸よりも機械的強度において劣るため、合成樹脂製の蝶番軸に局部的に加わる大きな剪断力に耐えられず、蝶番軸が破壊されやすいという問題があった。
【0008】
そこで、本発明は、上記した従来技術における問題点を解消すべく創案されたもので、合成樹脂製の蝶番軸を用いた化粧用コンパクト容器等の容器の蝶番構造において、容器本体若しくは蓋体に開回動方向の外力が加わった際に、てこ作用による作用力が剪断力として、容器本体と蓋体とを結合する蝶番軸に加わるのを阻止することを技術的課題とし、もって合成樹脂製の蝶番軸の破壊を防止して、容器の耐久性と安全性を高めることを目的とする。
【0009】
【課題を解決するための手段】
上記技術的課題を解決する本発明の内、請求項1に記載した発明の手段は、
収納部を形成した容器本体の後端部に設けた蝶番片に穿設した軸孔と、蓋体の後端部に設けた蝶番片に穿設した軸孔とに合成樹脂製の蝶番軸を挿通し、容器本体と蓋体とを開閉回動自在に結合する容器の蝶番構造であること、
容器本体の蝶番片を設けた部分以外の、蓋体の蝶番片に対向する後端部に突設した突起部に係止突部設けること
蓋体の蝶番片に、容器本体に対する蓋体の開方向への回動限で、係止突部に突き当たる当接部を設けこの当接部と係止突部との突き当りにより、容器本体の後端部と蓋体とが突き当たった点を支点とする、容器本体若しくは蓋体に加わった力によるてこ作用の作用力を受け止めること、
にある。
【0010】
蝶番軸を回転軸として、容器本体に対して蓋体を開方向に回動させると、容器本体の後端部に蓋体が突き当って、回動がストップし、容器本体に対する蓋体の回動限となる。
【0011】
容器本体に対する蓋体の開方向への回動限において、容器本体若しくは蓋体に開回動方向の外力が加わわると、この外力が容器本体と蓋体とを結合している蝶番軸及び容器本体の後端部に蓋体が突き当たっている部分に向かって作用する。
【0012】
そして、容器本体若しくは蓋体に外力が加わった部分が力点となり、容器本体の後端部に蓋体が突き当たった部分が支点となって、作用点となる蝶番軸にてこ作用による作用力が剪断力として加わろうとする。
【0013】
蓋体の蝶番片に設けた当接部が、容器本体の後端部に設けた突起部の係止突部に突き当たることによって、てこ作用により蝶番軸に加わろうとする作用力を受け止めるため、蝶番軸にてこ作用による作用力が剪断力として加わらない。
【0014】
請求項2記載の発明は、請求項1記載の発明の構成に、突起部を、軸孔よりも上位に設けるとともに、この突起部の先端部に、容器本体に対する蓋体の開方向への回動限において、軸孔よりも上位で、前方から蓋体の蝶番片に設けた当接部が突き当たる係止突部を垂下設したこと、を加えたものである。
【0015】
容器本体に対する開方向への蓋体の回動限で、容器本体若しくは蓋体に開回動方向の外力が加わった場合に、この外力が加わった部分を力点とし、容器本体の後端部に蓋体が突き当たった部分が支点となって、作用点となる蝶番軸に、外力によるてこ作用による作用力が加わろうとする。
【0016】
蝶番軸の下位で、支点となる容器本体の後端部に蓋体が突き当たった部分に対して、蓋体の蝶番片に設けた当接部が、容器本体の後端部に突設した突起部の係止突部に、蝶番軸の上位で、かつ、間に蝶番軸を挟んだ略反対側の位置で突き当たって、てこ作用により蝶番軸に加わろうとする作用力のほぼ全てを有効に受け止めるため、てこ作用による作用力が剪断力として蝶番軸に加わろうとするのを確実に阻止する。
【0017】
請求項3記載の発明は、請求項2記載の発明の構成に、蓋体の蝶番片に、容器本体と蓋体との回動範囲で、係止突部が摺接するカム面を設けたこと、を加えたものである。
【0018】
容器本体に対して蓋体を回動すると、係止突部がカム面を摺接して、摩擦抵抗力が発生し、この摩擦抵抗力により、容器本体に対して蓋体を一定角度のままで保持するフリーストップ機能を発揮する。
【0019】
また、カム面を当接部から連設したため、容器本体に対する開方向への蓋体の回動限まで、係止突部とカム面との摩擦抵抗力によってフリーストップ機能を確実に発揮し、容器本体に対して垂直に立設するまで蓋体が開方向へ回動した後、蓋体の自重によって、蓋体が勢いよく開方向への回動して、容器本体の後端部に蓋体が突き当たり、容器本体若しくは蓋体に開回動方向の力が加わろうとするのを阻止する。
【0020】
【発明の実施の形態】
以下、本発明の一実施例を、図面を参照にしながら説明する。
図1は、化粧用コンパクト容器1の分解斜視図、図2は、容器1の平面図、図3は、図2の縦断面のX-X矢視図である。
【0021】
図1乃至図3に示すように、化粧用コンパクト容器1は、ポリプロピレン製の容器本体2と、同じくポリプロピレン製の蓋体3と、ナイロン製の蝶番軸9とから構成されている。
【0022】
容器本体2は、化粧料若しくは化粧用パフを収納する二つの収納部6を設けた角皿体状に形成し、後端部の両端から突出する二つの蝶番片4を設け、蝶番片4には、蝶番軸9を挿通する軸孔5を穿設している。
【0023】
蓋体3は、後端部の中央部から一つの蝶番片7を垂下設し、蝶番片7には、蝶番軸9を挿通する軸孔8を穿設している。
【0024】
容器1は、容器本体2の蝶番片4と、蓋体3の蝶番片7とを組合せ、軸孔5及び軸孔8に蝶番軸9を挿通し、容器本体2と蓋体3とを開閉回動自在に蝶番結合している。
【0025】
なお、蓋体3の前端部の中央には、閉塞用突起部15を突設し、容器本体2の前端部中央に、閉塞用突起部15を嵌合する凹部16を設け、この凹部16内に閉塞用突起部15を引っ掛けて、容器本体2に対する蓋体3の閉塞を維持する閉塞用係止部17を設け、容器本体2に対する蓋体3の閉塞を維持する構造としている。
【0026】
図4は、閉塞した状態の容器本体2と蓋体3の蝶番構造の縦断面を示す一部拡大図である。
【0027】
図4に示すように、容器本体2は、蝶番片4を設けた部分以外の後端部の、蝶番片4に近接した位置に、後方に突出する二つの突起部10を突設し、この突起部10の先端部に係止突部11を垂下設している。
【0028】
一方、蓋体3は、蝶番片7の前面に容器本体2の突起部10が遊合する二つの縦溝状の凹嵌部12を設け、この凹嵌部12の一端に、容器本体2に対する蓋体3の回動限で、係止突部11に突き当たる当接部13を設け、この当接部13に円弧状のカム面14を連設している。
【0029】
カム面14は、容器本体2に対して蓋体3を閉塞した場合に、突起部10の係止突部11がカム面14に当って、閉塞を維持する蓋体3の前端部に設けた閉塞用突起部15と容器本体2の閉塞用係止部17との係合の邪魔とならないように、係止突部11とカム面14との間に間隙を設けて形成している。
【0030】
図5は、容器本体2に対する蓋体3の回動範囲中の、略45°の開角度姿勢となった状態における、また図6は、蓋体3の全開状態における容器本体2と蓋体3との蝶番構造の縦断面を示す一部拡大図である。
【0031】
図5および図6に示すように、容器本体2に対する蓋体3の全回動範囲において、容器本体2の凹嵌部12に遊合している突起部10の係止突部11の先端部が、カム面14に径方向から摺接する。
【0032】
このため、容器本体2に対する蓋体3の回動時に、係止突部11とカム面14との間に適度な摩擦抵抗力が発生し、蝶番軸9と軸孔8若しくは軸孔5との摩擦接触による摩擦抵抗力によって発揮されるフリーストップ機能を発揮する。
【0033】
また、カム面14を当接部13に連設したため、容器本体2に対する蓋体3の開方向への回動限である当接部13が係止突部11に突き当たるまで、カム面14と当接部13との摩擦抵抗力によって、容器1のフリーストップ機能を発揮する。
【0034】
すなわち、容器本体2に対して蓋体3が垂直に立設するまで開方向へ回動した後、蓋体3の自重によって開方向へ蓋体3が回動しようとするのを確実なフリーストップ機能によって阻止し、蓋体3の自重によって蓋体3が勢いよく開方向へ回動して、容器本体2の後端部に蓋体3が突き当たり、容器本体2若しくは蓋体3に力が加わろうとするのを阻止する。
【0035】
図7は、容器本体2に対する開方向への蓋体3の回動限における容器本体2と蓋体3の縦断面の一部拡大図である。
【0036】
図7に示すように、蓋体3は、容器本体2の後端部に突き当たるまで開方向へ回動し、この容器本体2の後端部に蓋体3が突き当たった位置が、容器本体2に対する開方向への蓋体3の回動限となる。
【0037】
蝶番軸9の下位で容器本体2の後端部に蓋体3が突き当たった部分に対して、蝶番軸9の上位で、かつ、間に蝶番軸9を挟んだ略反対側の位置で、当接部13が前方から係止突部11に突き当たる。
【0038】
容器本体2に対する開方向への蓋体3の回動限において、容器本体2若しくは蓋体3に開回動方向への外力が加わり、この外力が加わった部分から、蝶番軸9及び容器本体2の後端部に蓋体3が突き当たった部分に向かって外力が作用した場合、容器本体2若しくは蓋体3の外力が加わった部分が力点となり、容器本体2の後端部に蓋体3が突き当たった部分が支点となって、この力点及び支点に対する作用点となる蝶番軸9にてこ作用による作用力が加わろうとする。
【0039】
この容器本体2に対する開方向への蓋体3の回動限において、蝶番軸9の下位で、支点となる容器本体2の後端部に蓋体3が突き当たった部分に対して、蝶番軸9の上位で、かつ、蝶番軸9を間に挟んだ略反対側の位置で、当接部13が係止突部11に突き当たって、蝶番軸9に加わろうとするてこ作用による作用力のほぼ全てを受け止めて、てこ作用により蝶番軸9に作用力が剪断力として加わろうとするのを確実に阻止し、蝶番軸9の破壊を防止する。
【0040】
また、容器本体2の後端部の蝶番片4に近接した位置に二つの突起部10を設けたため、この二つの突起部10の係止突部11に当接部13が突き当たり、二つの軸孔に跨った蝶番軸9の部分に特に大きく加わろうとするてこ作用による作用力を受け止めて、蝶番軸9にてこ作用による作用力が大きな剪断力として加わろうとするのを確実に阻止する。
【0041】
【発明の効果】
本発明は、上記した構成となっているので、以下に示す効果を奏する。
請求項1に記載した発明にあっては、容器本体に対する開方向への蓋体の回動限で、容器本体若しくは蓋体に開回動方向へ外力が加わり、この外力が加わった部分が力点となり、容器本体の後端部に蓋体が突き当った部分が支点となった場合に、作用点となる蝶番軸に加わろうとするてこ作用によって生じる作用力を、蓋体の蝶番片に設けた当接部が、容器本体の後端部に突設した突起部の係止突部に当接することによって受け止めるため、蝶番軸にてこ作用による作用力が剪断力として加わろうとするのを阻止し、蝶番軸の破壊を防止して、容器の安全性と耐久性を向上する。
【0042】
また、容器本体の蝶番片を設けた部分以外の、蓋体の蝶番片に対向する後端部に突設した突起部に設けた係止突部と、この係止突部に突き当たる当接部とからなる簡単な構造で、容器本体に対する開方向への蓋体の回動限において、蝶番軸にてこ作用による作用力が剪断力として加わろうとするのを阻止する蝶番構造とすることができる。
【0043】
請求項2記載の発明にあっては、容器本体に対する開方向への蓋体の回動限で、容器本体若しくは蓋体に開回動方向への外力が加わった場合に、この外力が加わった部分が力点となり、容器本体の後端部に蓋体が突き当たった部分が支点となって、作用点となる蝶番軸に加わろうとするてこ作用による作用力のほぼ全てを、蝶番軸の下位で支点となる容器本体の後端部に蓋体が突き当たった部分に対して、蝶番軸の上位で、かつ、間に蝶番軸を挟んだ略反対側の位置で、蓋体の蝶番片に設けた当接部が容器本体の後端部に設けた突起部の係止突部に、前方から突き当たって受け止めるため、蝶番軸にてこ作用による作用力が剪断力として加わろうとするのを確実に阻止できる。
【0044】
請求項3記載の発明にあっては、容器本体に対する蓋体の回動範囲で、係止突部が摺接するカム面を設けたため、軸孔と蝶番軸との間の摩擦抵抗力によって発揮するフリーストップ機能を、係止突部がカム面に摺接することによって発生する摩擦抵抗力により発揮し、容器の適度なフリーストップ機能を担保する。
【0045】
また、カム面を当接部に連設したため、容器本体に対する開方向への蓋体の回動限まで、係止突部がカム面に摺接して生じる摩擦抵抗力により確実にフリーストップ機能を発揮し、容器本体に対して蓋体が垂直に立設するまで開方向へ回動した後、蓋体の自重によって容器本体に対して開方向へ蓋体が勢い良く回動し、容器本体の後端部に蓋体が突き当たって、容器本体若しくは蓋体に力が加わろうとするのを阻止する。

BACKGROUND OF THE INVENTION
The present invention relates to a hinge structure of a container in which a container main body and a lid are coupled so as to be freely openable and closable, and relates to a hinge structure that prevents a shearing force applied to a hinge shaft that couples the container main body and the lid.
[0002]
[Prior art]
As a cosmetic compact container, a combination of a hinge piece provided with a shaft hole provided at the rear end of the container body and a hinge piece provided with a shaft hole provided similarly at the rear end of the lid body, 2. Description of the Related Art A hinge shaft is inserted through a hole, and a lid body is connected to the container body so as to be freely opened and closed.
[0003]
A cosmetic compact container has a hinge axis as a rotation axis, and when a strong external force is applied to one of the container body or the lid body with the lid body rotated with respect to the container body, The container body or lid with added pressure tends to shift and concentrate on the hinge shaft spanning the shaft hole drilled in the hinge piece of the container body and the shaft hole drilled in the hinge piece of the lid body. A large shearing force works and the hinge shaft is easily broken.
[0004]
In particular, when any external force is applied in the opening rotation direction of the container body or lid in the limit of rotation of the lid in the opening direction with respect to the container body, the portion where the external force is applied becomes a power point, and the lid is attached to the rear end of the container body. The hinge shaft acts as a point of action against the force point with the part where the body hits as a fulcrum, and a large shearing force due to this action acts on the hinge shaft, which sometimes destroys the hinge shaft.
[0005]
For this reason, conventionally, a hinge shaft made of metal having a high mechanical strength has been used as a hinge shaft for connecting the container body and the lid.
[0006]
On the other hand, in recent years, considering the advantages such as avoiding the trouble of separating and collecting the container body, the lid, and the hinge shaft as the same material, reducing the weight of the container, and reducing the manufacturing cost. Synthetic resin hinge shafts are often used in cosmetic compact containers.
[0007]
[Problems to be solved by the invention]
However, in recent years, the hinge shaft made of synthetic resin often used for cosmetic compact containers is inferior in mechanical strength to the hinge shaft made of metal, so that a large shear force is locally applied to the hinge shaft made of synthetic resin. There was a problem that the hinge shaft could not be tolerated and was easily broken.
[0008]
Therefore, the present invention was devised to solve the above-described problems in the prior art, and in a hinge structure of a container such as a compact container for makeup using a hinge shaft made of synthetic resin, the container body or lid When an external force in the opening and turning direction is applied, the technical problem is to prevent the acting force of the lever action from being applied as a shearing force to the hinge shaft that joins the container body and lid, and is made of synthetic resin. The purpose is to increase the durability and safety of the container by preventing breakage of the hinge shaft.
[0009]
[Means for Solving the Problems]
Among the present invention for solving the above technical problems, the means of the invention described in claim 1 is:
A hinge pin made of synthetic resin is formed in the shaft hole drilled in the hinge piece provided at the rear end of the container body that forms the storage portion and the shaft hole drilled in the hinge piece provided in the rear end of the lid. A container hinge structure that inserts and connects the container body and the lid so that it can be freely opened and closed;
Other than the portion provided with the hinge piece of the container body, providing the locking projection to the projection portion projecting from the rear end opposite the hinge piece of the lid,
The hinge piece of the lid, in rotation limit in the opening direction of the lid relative to the container body, the abutment portion that abutting the locking projection provided by abutment between the abutment portion and the locking projection Receiving the leverage of the lever action by the force applied to the container body or lid, with the point where the rear end of the container body and the lid abut as a fulcrum,
It is in.
[0010]
When the lid is rotated in the opening direction with respect to the container body with the hinge shaft as the rotation axis, the lid abuts against the rear end of the container body, the rotation stops, and the lid body rotates relative to the container body. It becomes a limit.
[0011]
When an external force in the opening rotation direction is applied to the container main body or the lid body in the limit of rotation of the lid body in the opening direction with respect to the container main body, the hinge shaft and the container are connected to the container main body and the lid body. It acts toward the part where the lid is in contact with the rear end of the main body.
[0012]
The part where external force is applied to the container body or lid body becomes the force point, the part where the lid body abuts the rear end of the container body serves as a fulcrum, and the acting force due to this action is sheared at the hinge shaft as the action point. Try to join as force.
[0013]
Since the abutting portion provided on the hinge piece of the lid body abuts against the locking projection of the protruding portion provided at the rear end portion of the container body, the acting force to be applied to the hinge shaft by the lever action is received. The working force due to this action is not applied to the shaft as a shearing force.
[0014]
According to the second aspect of the present invention, in the configuration of the first aspect of the present invention, the protrusion is provided above the shaft hole, and the tip of the protrusion is rotated in the opening direction of the lid with respect to the container body. In the limit of movement, a locking projection is provided above the shaft hole, and a locking projection that abuts against the abutment provided on the hinge piece of the lid from the front.
[0015]
When the external force in the opening rotation direction is applied to the container body or the lid body at the limit of rotation of the lid body in the opening direction with respect to the container body, the portion where this external force is applied is the force point, and the rear end of the container body The portion where the lid abuts serves as a fulcrum, and an action force due to a lever action due to an external force is applied to the hinge shaft as an action point.
[0016]
Projection in which the abutment provided on the hinge piece of the lid protrudes from the rear end of the container body against the part where the lid hits the rear end of the container body, which is the fulcrum, below the hinge shaft It hits the locking projection of the part at a position on the upper side of the hinge shaft and on the substantially opposite side with the hinge shaft in between, and effectively receives almost all of the acting force to be applied to the hinge shaft by lever action Therefore, the action force due to the lever action is reliably prevented from being applied to the hinge shaft as a shearing force.
[0017]
The invention described in claim 3 is the configuration of the invention described in claim 2, wherein the hinge piece of the lid is provided with a cam surface on which the locking projection slides in the rotational range of the container body and the lid. , Is added.
[0018]
When the lid is rotated with respect to the container body, the locking projection slides on the cam surface to generate a frictional resistance force, and this frictional resistance force keeps the lid body at a certain angle with respect to the container body. Demonstrate the free-stop function to hold.
[0019]
In addition, since the cam surface is continuously provided from the abutment portion, the free stop function is reliably exhibited by the frictional resistance force between the locking projection and the cam surface until the limit of rotation of the lid body in the opening direction with respect to the container body, After the lid rotates in the opening direction until it stands vertically with respect to the container body, the lid body vigorously rotates in the opening direction by the weight of the lid body, and the lid is placed on the rear end of the container body. The body hits and prevents the force in the opening rotation direction from being applied to the container body or the lid.
[0020]

A gap is provided between the locking projection 11 and the cam surface 14 so as not to obstruct the engagement between the closing projection 15 and the closing locking portion 17 of the container body 2.
[0030]
FIG. 5 shows a state in which the open angle posture is approximately 45 ° in the rotation range of the lid body 3 with respect to the container body 2, and FIG. 6 shows the container body 2 and the lid body 3 in the fully opened state of the lid body 3. It is a partially expanded view which shows the longitudinal cross-section of a hinge structure.
[0031]
As shown in FIGS. 5 and 6, in the entire rotation range of the lid 3 with respect to the container main body 2, the distal end portion of the locking protrusion 11 of the protrusion 10 that is loosely engaged with the concave fitting portion 12 of the container main body 2. However, it comes into sliding contact with the cam surface 14 from the radial direction.
[0032]
For this reason, when the lid 3 is rotated with respect to the container body 2, an appropriate frictional resistance force is generated between the locking projection 11 and the cam surface 14, and the hinge shaft 9 and the shaft hole 8 or the shaft hole 5 Demonstrates a free-stop function that is demonstrated by frictional resistance caused by frictional contact.
[0033]
Further, since the cam surface 14 is continuously provided to the contact portion 13, the cam surface 14 and the cam surface 14 are contacted until the contact portion 13, which is the limit of rotation of the lid 3 in the opening direction with respect to the container body 2, hits the locking protrusion 11. The free stop function of the container 1 is exhibited by the frictional resistance with the contact portion 13.
[0034]
In other words, after the lid body 3 is rotated in the opening direction until the lid body 3 stands vertically with respect to the container body 2, the lid body 3 tries to rotate in the opening direction by the weight of the lid body 3. It is blocked by the function, and the lid body 3 vigorously rotates in the opening direction due to the weight of the lid body 3, the lid body 3 hits the rear end of the container body 2, and force is applied to the container body 2 or the lid body 3. Stop trying.
[0035]
FIG. 7 is a partially enlarged view of a longitudinal section of the container body 2 and the lid body 3 in the limit of rotation of the lid body 3 in the opening direction with respect to the container body 2.
[0036]
As shown in FIG. 7, the lid 3 rotates in the opening direction until it abuts against the rear end of the container body 2, and the position where the lid 3 abuts against the rear end of the container body 2 is the container body 2. This is the limit of rotation of the lid 3 in the opening direction with respect to.
[0037]
The upper part of the hinge shaft 9 and the substantially opposite side of the hinge shaft 9 between the portion where the lid 3 abuts the rear end of the container body 2 below the hinge shaft 9. The contact portion 13 abuts against the locking projection 11 from the front.
[0038]
In the limit of rotation of the lid body 3 in the opening direction relative to the container body 2, an external force in the opening rotation direction is applied to the container body 2 or the lid body 3, and the hinge shaft 9 and the container body 2 are applied from the portion where the external force is applied. When an external force is applied toward the portion where the lid 3 abuts against the rear end of the container, the portion where the external force of the container body 2 or the lid 3 is applied becomes a power point, and the lid 3 is attached to the rear end of the container body 2. The abutted portion serves as a fulcrum, and an acting force due to this action is applied to the force point and the hinge shaft 9 serving as an action point for the fulcrum.
[0039]
In the limit of rotation of the lid body 3 in the opening direction with respect to the container body 2, the hinge shaft 9 is located below the hinge shaft 9 with respect to the portion where the lid body 3 abuts the rear end portion of the container body 2 serving as a fulcrum. And the contact portion 13 abuts against the locking projection 11 at a position substantially opposite to the hinge shaft 9 between them, and almost all of the acting force due to the lever action to be applied to the hinge shaft 9 is obtained. In this way, it is possible to reliably prevent the acting force from being applied to the hinge shaft 9 as a shearing force by the lever action and prevent the hinge shaft 9 from being broken.
[0040]
In addition, since the two protrusions 10 are provided at a position close to the hinge piece 4 at the rear end of the container body 2, the abutment 13 abuts against the locking protrusion 11 of the two protrusions 10, and the two shafts The action force caused by the lever action that is particularly greatly applied to the portion of the hinge shaft 9 straddling the hole is received, and the action force caused by the lever action on the hinge shaft 9 is reliably prevented from being applied as a large shearing force.
[0041]
【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be obtained.
In the invention described in claim 1, an external force is applied to the container body or the lid in the opening rotation direction at the limit of rotation of the lid in the opening direction with respect to the container body, and the portion where the external force is applied is a power point. When the part where the lid hits the rear end of the container body becomes a fulcrum, the action force generated by the lever action to add to the hinge shaft as the action point is provided on the hinge piece of the lid Since the abutting portion is received by abutting against the locking projection of the projection protruding from the rear end of the container body, the acting force due to this action is prevented from being applied as a shearing force on the hinge shaft, Prevents the destruction of the hinge shaft and improves the safety and durability of the container.
[0042]
In addition to the portion provided with the hinge piece of the container body, a locking protrusion provided on the protruding portion protruding from the rear end portion facing the hinge piece of the lid, and a contact portion that contacts the locking protrusion The hinge structure that prevents the action force due to this action from being applied to the hinge shaft as a shear force at the limit of rotation of the lid body in the opening direction with respect to the container body can be achieved.
[0043]
In the invention of claim 2, when an external force in the opening rotation direction is applied to the container body or the lid body in the limit of rotation of the lid body in the opening direction with respect to the container body, this external force is applied. The part becomes a force point, and the part where the lid abuts on the rear end of the container body becomes a fulcrum, and almost all of the action force due to the lever action to be applied to the hinge axis that is the action point is supported at the lower part of the hinge axis. The upper part of the hinge shaft on the rear end of the container body that is Since the contact portion abuts against the engaging protrusion of the protrusion provided at the rear end of the container body from the front, the contact force can be reliably prevented from being applied as a shearing force by the hinge shaft.
[0044]
In the invention according to claim 3, since the cam surface on which the locking projection slides is provided in the rotation range of the lid with respect to the container main body, the friction resistance force between the shaft hole and the hinge shaft exerts. The free stop function is exerted by the frictional resistance generated when the locking protrusion slides on the cam surface, thereby ensuring an appropriate free stop function of the container.
[0045]
In addition, since the cam surface is connected to the abutment portion, the free stop function is ensured by the frictional resistance generated when the locking projection slides against the cam surface until the lid body pivots in the opening direction relative to the container body. The lid body is pivoted in the opening direction until the lid body stands vertically with respect to the container body, and then the lid body vigorously pivots in the opening direction with respect to the container body by its own weight. This prevents the lid from abutting on the rear end portion and applying force to the container body or the lid.
