すなわち、鍔部３０は、少なくとも、その連結箇所から蓋周壁２２の前面及びキャップ周壁１０の前面に沿って下方へ延びる第１状態と、当該連結箇所から略前方へ庇状に延びる第２状態との間で回転可能に形成されている。なお、“キャップ周壁の前面に沿って”とは、“当該前面に当接あるいは近接して”という程度の意味である。
そして本実施形態では、前記第１状態において鍔部３０の全部が前記収納溝Ｇに収納されており、この状態での鍔部３０の前面は、蓋周壁２２及びキャップ周壁１０の外周面とほぼ面一に形成されている。これにより、ヒンジキャップの体裁が良好となる。
鍔部３０は、本実施形態では、前記第２状態において上方へ弯曲する形状（図示例ではアーチ状）を有する曲がり板部である。この鍔部３０の左右方向両側部３０ｂは、前記収納溝Ｇの両側面に近接している。
図２に示すように、前記鍔部３０の基端部Ｅ１は、第１状態で下方へ水平になっており、鍔部３０を第２状態へ回転させたときに第１溝部Ｇ１の平坦な溝底面ＧＢ１の上部に面接するように形成している。
他方、前記鍔部３０の先端部Ｅ２は、図示例では、図４及び図５に示す如く半円形状に形成している。もっともこれら形状は適宜変更することができる。
第２状態での鍔部３０の水平方向への突出長は、ヒンジキャップを装着した容器体の胴部の輪郭より外側にはみ出さないようにすることが外観上好適である。
前記鍔部３０の先端部Ｅ２には、下方から見て左右方向に延びるリブ受溝３２を凹設して、第１状態において、このリブ受溝３２内に係合リブ１２が、後述の開操作により着脱が可能な程度の深さで嵌合されるように設けている（図３参照）。これら係合リブ１２及びリブ受溝３２は、鍔部３０を収納溝Ｇ内に係止する係止手段Ｊを形成し、これにより、未使用の状態で収納溝Ｇ内から鍔部３０が浮き上がることを防止できる。なお、図示例と異なり、鍔部３０の先端部Ｅ２に係合リブを、また収納溝Ｇの溝端面ＧＥにリブ受溝を形成しても構わない。さらに係合リブ及びリブ受溝の形状は適宜変更することができる。
また前記第１状態においてリブ受溝３２の内側には、角取り部３４を形成している。これにより、第２状態から第１状態へ鍔部３０を回転させるときに、前記角取り部３４が係合リブ１２を乗り越えることが容易となる。 The collar portion 30 is attached to the front side of the lid body 16 as a grip portion of the lid body. The flange portion 30 is formed as a plate portion wide in the left-right direction, and the intermediate portion 30a in the left-right direction is rotatably connected to the front surface of the lid peripheral wall 22 via a second hinge 26.
That is, the collar portion 30 has at least a first state extending downward along the front surface of the lid peripheral wall 22 and the front surface of the cap peripheral wall 10 from the connecting portion, and a second state extending substantially forward from the connecting portion in an eaves shape. It is formed rotatably between. In addition, "along the front surface of the peripheral wall of the cap" means "in contact with or in close proximity to the front surface".
In the present embodiment, the entire collar portion 30 is housed in the storage groove G in the first state, and the front surface of the collar portion 30 in this state is substantially equal to the outer peripheral surfaces of the lid peripheral wall 22 and the cap peripheral wall 10. It is formed flush with each other. This improves the appearance of the hinge cap.
In the present embodiment, the collar portion 30 is a bent plate portion having a shape that bends upward (arch shape in the illustrated example) in the second state. The left and right side portions 30b of the flange portion 30 are close to both side surfaces of the storage groove G.
As shown in FIG. 2, the base end portion E1 of the flange portion 30 is horizontal downward in the first state, and when the collar portion 30 is rotated to the second state, the first groove portion G1 is flat. It is formed so as to come into contact with the upper part of the groove bottom surface GB1.
On the other hand, the tip portion E2 of the flange portion 30 is formed in a semicircular shape as shown in FIGS. 4 and 5 in the illustrated example. However, these shapes can be changed as appropriate.
It is preferable in appearance that the horizontal protrusion length of the collar portion 30 in the second state does not protrude outside the contour of the body portion of the container body to which the hinge cap is attached.
A rib receiving groove 32 extending in the left-right direction when viewed from below is recessed in the tip portion E2 of the flange portion 30, and in the first state, the engaging rib 12 is opened in the rib receiving groove 32, which will be described later. It is provided so that it can be fitted to a depth that allows it to be attached and detached by operation (see FIG. 3). The engaging rib 12 and the rib receiving groove 32 form a locking means J for locking the flange portion 30 in the storage groove G, whereby the collar portion 30 is lifted from the storage groove G in an unused state. Can be prevented. Unlike the illustrated example, an engaging rib may be formed on the tip portion E2 of the flange portion 30, and a rib receiving groove may be formed on the groove end surface GE of the storage groove G. Further, the shapes of the engaging rib and the rib receiving groove can be changed as appropriate.
Further, in the first state, a corner cutting portion 34 is formed inside the rib receiving groove 32. As a result, when the collar portion 30 is rotated from the second state to the first state, the cornering portion 34 can easily get over the engaging rib 12.

本実施形態の第２ヒンジ２６は、第１状態と第２状態との途中の平衡状態（図７（Ｂ）参照）を境として、第１状態と平衡状態との間では第１状態側へ付勢力が働き、平衡状態と第２状態との間では第２状態側へ付勢力が働く、従来公知の弾性反転式ヒンジとして形成されている。弾性反転式ヒンジは、例えば薄肉ヒンジと弾性伸縮可能な板バネの組み合わせで形成することができる。図示例の第２ヒンジは、前記支持用突部２５の上辺２５ａに付設された一つの薄肉ヒンジ２６ａと、薄肉ヒンジ２６ａの左右両側に配置され、前記支持用突部２５の斜辺２５ｂ及び鍔部３０の裏面の間に掛け渡された一対のバネ板２６ｂとで形成されている。もっとも、図示例とは逆に、左右方向の内側に一つのバネ板と、左右方向の両側に一対の肉薄ヒンジとで、第２ヒンジを構成してもよい。更に弾性反転式ではなくても、従来公知のヒンジ機構であればどのような構成でも第２ヒンジとして採用することができる。 The second hinge 26 of the present embodiment moves to the first state side between the first state and the equilibrium state with the equilibrium state (see FIG. 7B) in the middle between the first state and the second state as a boundary. It is formed as a conventionally known elastic reversing hinge in which an urging force acts and an urging force acts toward the second state side between the equilibrium state and the second state. The elastic reversing hinge can be formed by, for example, a combination of a thin-walled hinge and an elastically expandable leaf spring. The second hinge of the illustrated example is arranged on both the left and right sides of one thin-walled hinge 26a attached to the upper side 25a of the supporting protrusion 25 and the thin-walled hinge 26a, and the hypotenuse 25b and the collar portion of the supporting protrusion 25. It is formed of a pair of spring plates 26b spanned between the back surfaces of 30. However, contrary to the illustrated example, the second hinge may be formed by one spring plate on the inside in the left-right direction and a pair of thin hinges on both sides in the left-right direction. Further, even if it is not an elastic reversal type, any conventionally known hinge mechanism can be adopted as the second hinge.

前記構成において、ヒンジキャップを使用しない状態では、前記鍔部３０は、第２ヒンジ２６から下方へ垂下した第１状態としておくとよい。
ヒンジキャップを容器体の口頸部へ装着して、初回使用するときに、鍔部３０の先端部Ｅ２に指を掛けて、第２ヒンジ２６から前方へ延びる第２状態へと回転させる。これにより鍔部３０が前方へ長く延びた状態で使用できる。
蓋体１６を開くときには、第２状態より、鍔部３０の左右方向中間部３０ａの裏面に指を掛けて引き上げると、図８(Ａ)に示す如く、鍔部３０の基端部Ｅ１が第２ヒンジ２６の上方で蓋周壁２２の前面に突き当たるので、鍔部３０はこれ以上第２ヒンジ２６を中心として蓋体１６に対して回転することができない。その状態で鍔部３０の引上げを続けると、前記基端部Ｅ１が蓋周壁２２の前面に押圧力ｆを作用させるので、第１ヒンジ１４を中心とする回転モーメントが作用する。これにより、図８（Ｂ）に示すように鍔部３０及び蓋体１６は、第１ヒンジ１４を中心として回転し、蓋体１６が開蓋される。
この際に鍔部３０及び蓋体１６は一個のレバーとして働く。支点を第１ヒンジ１４、力点を鍔部３０の先端部Ｅ２付近、作用点を注出筒８及び栓棒２０の嵌合箇所と考えると、鍔部３０を設けずに蓋周壁２２の前部に指を掛けて操作する場合に比べて、支点と力点との距離が長くなるから、テコの原理により、より小さな力で蓋体１６を開蓋することができる。
従って子供のように指の力が弱い利用者でも容易に開蓋することができ、誰にでも使い易いユニバーサル型のヒンジキャップを提供することができる。 In the above configuration, when the hinge cap is not used, the collar portion 30 may be in the first state of hanging downward from the second hinge 26.
The hinge cap is attached to the mouth and neck of the container body, and when used for the first time, a finger is hung on the tip E2 of the collar 30 to rotate the hinge cap into a second state extending forward from the second hinge 26. As a result, the collar portion 30 can be used in a state of being extended forward.
When opening the lid 16, from the second state, when the back surface of the left-right intermediate portion 30a of the collar portion 30 is pulled up with a finger, as shown in FIG. 8A, the base end portion E1 of the collar portion 30 becomes the first. Since the flange portion 30 abuts on the front surface of the lid peripheral wall 22 above the two hinges 26, the collar portion 30 cannot rotate around the second hinge 26 any more with respect to the lid body 16. If the collar portion 30 is continuously pulled up in this state, the base end portion E1 exerts a pressing force f on the front surface of the lid peripheral wall 22, so that a rotational moment centered on the first hinge 14 acts. As a result, as shown in FIG. 8B, the collar portion 30 and the lid 16 rotate around the first hinge 14, and the lid 16 is opened.
At this time, the collar portion 30 and the lid body 16 act as one lever. Considering that the fulcrum is the first hinge 14, the force point is near the tip E2 of the flange portion 30, and the point of action is the fitting location of the injection cylinder 8 and the plug rod 20, the front portion of the lid peripheral wall 22 without the collar portion 30 is provided. Since the distance between the fulcrum and the point of effort is longer than in the case of operating with a finger on the lid, the lid 16 can be opened with a smaller force by the principle of leverage.
Therefore, even a user with weak finger strength such as a child can easily open the lid, and a universal hinge cap that is easy for anyone to use can be provided.
