しかしながら、ロック部材とストッパ部とは、特許文献4を除き、上下方向に配列されているため、ロック機構の上下方向が長くなり、コンパクト化に難点がある。   However, since the lock member and the stopper portion are arranged in the vertical direction except for Patent Document 4, the vertical direction of the lock mechanism becomes long, and there is a difficulty in downsizing.

また、特許文献4では、ロック部材とストッパ部とは前後方向に配列されているため、上下方向で部材の配置が長くなる欠点は解決されているが、ロック部材とストッパ部とは互いに前後方向で連携しているため、両者の寸法が僅かに相違していても、両者の連携に支障を来たすおそれがある。   Further, in Patent Document 4, since the lock member and the stopper portion are arranged in the front-rear direction, the disadvantage that the arrangement of the members becomes longer in the up-down direction is solved, but the lock member and the stopper portion are in the front-rear direction. Therefore, even if the dimensions of the two are slightly different, there is a risk of hindering the cooperation between the two.

また、他の特許文献1,2,3においてもロック部材とストッパ部とは互いに連携しているため、寸法の僅かな相違により、両者の連携に支障を来たすおそれがあった。   Also, in other Patent Documents 1, 2, and 3, since the lock member and the stopper portion are linked to each other, there is a possibility that the linkage between the two may be hindered due to a slight difference in dimensions.

本考案は、ロック部材とストッパ部との配置を工夫することで、コンパクトなロック機構を備えた口栓構造の提供を目的としている。また、本考案は、ロック部材とストッパ部との寸法精度のバラツキにも対応できる口栓構造の提供も目的としている。   An object of the present invention is to provide a plug structure having a compact lock mechanism by devising the arrangement of the lock member and the stopper portion. Another object of the present invention is to provide a plug structure that can cope with variations in dimensional accuracy between the lock member and the stopper portion.

上記目的を達成するために、本考案においては、容器本体の口元外周に注出口を有する口栓本体が螺着され、前記口栓本体に前記注出口を開閉可能とする蓋体がヒンジ軸を介して回動可能に設けられ、前記蓋体の回動端を口栓本体に対して閉姿勢にロック可能なロック機構が設けられた飲料容器の口栓装置において、前記ロック機構は、蓋体の回動端に設けられた係合部に係脱可能に係合する係合爪を上部に備え、前記係合部を係合爪に係合するロック姿勢と係合部を係合爪から解除するロック解除姿勢との間で横軸周りに揺動可能なロック部材と、前記ロック部材をロック姿勢においてその揺動を規制するストッパ部とを備え、前記ストッパ部は、口栓本体のロック部材よりも内側に配置され、口栓本体にロック部材とは独立して上下スライド可能に案内され、前記ロック部材には、その上下方向中間位置にストッパ部を操作可能とする中央窓が貫通形成され、前記中央窓を通して外側から前記ストッパ部を操作可能とする操作部が前記ストッパ部と一体形成されたことを特徴とする。   In order to achieve the above object, in the present invention, a cap body having a spout is screwed to the outer periphery of the mouth of the container body, and a lid that allows the spout to be opened and closed on the spout body has a hinge shaft. A lid device for a beverage container provided with a lock mechanism that is provided so as to be pivotable and capable of locking the pivot end of the lid body in a closed position with respect to the cap body.

Slide rails 27 are formed on both the left and right sides of the rear surface of the stopper portion 11 and are fitted into a pair of left and right guide walls 28 at the bottom of the storage chamber 13 as shown in FIG. It is guided to be slidable in the direction. This is because the stopper portion 11 is disposed inside the lock chamber 10 in the storage chamber 13 and is guided to the storage chamber 13 so as to be slidable up and down independently of the lock member 10.

また、ストッパ部11は、その側面に上下方向の縦穴30が貫通形成され、縦穴30に口栓本体側の収容室13の側面からのガイド軸31が挿入され、縦穴30の上下方向長さ分だけ上下方向に移動可能とされている。なお、縦穴30は、ストッパ部11の側面において左右方向に貫通形成される以外に、凹状に切欠き形成される態様であってもよい。   Further, the stopper portion 11 has a vertical hole 30 formed in the side surface so as to penetrate the stopper portion 11, and a guide shaft 31 is inserted into the vertical hole 30 from the side surface of the storage chamber 13 on the plug body side. It can only move up and down. In addition, the vertical hole 30 may be formed as a notch in a concave shape in addition to being formed through the side surface of the stopper portion 11 in the left-right direction.

ストッパ部11を上下移動方向の上位置において、その上姿勢を維持するためのストッパ部案内部材32が、口栓本体3の収容室13の底部に設けられている。そして、ストッパ部11の後端と案内部材32とのうちのいずれか一方に形成された窪み33と、他方に形成され窪み33に弾性的に接触する凸部34とを備え、前記窪み33に凸部34が嵌合することによりストッパ部11が上姿勢を維持できるようになっている。   A stopper guide member 32 is provided at the bottom of the storage chamber 13 of the plug body 3 in order to maintain the stopper 11 at the upper position in the vertical movement direction. And it has the hollow 33 formed in any one of the rear end of the stopper part 11 and the guide member 32, and the convex part 34 which is formed in the other and contacts the hollow 33 elastically, The stopper portion 11 can maintain the upper posture by fitting the convex portion 34.

本実施形態では、ストッパ部11の後面の中央に凸部34が形成され、これに対向するように案内部材32の案内片に窪み33が形成されている。なお、本例とは逆に、ストッパ部11の後面に窪み33を形成し、案内部材32に凸部34を形成する態様であってもよい。   In this embodiment, the convex part 34 is formed in the center of the rear surface of the stopper part 11, and the hollow 33 is formed in the guide piece of the guide member 32 so as to oppose this. In contrast to this example, a mode in which the recess 33 is formed on the rear surface of the stopper portion 11 and the convex portion 34 is formed on the guide member 32 may be adopted.

案内部材32は、図12に示すように、矩形枠状に形成され、その上辺の中央から側面視波形の案内片35が片持ち状に垂下されている。そして、ストッパ部11の上位置で、ストッパ部11の凸部34が案内片35の窪み33に弾性的に係合し、ストッパ部11の自重による下動を阻止している。   As shown in FIG. 12, the guide member 32 is formed in a rectangular frame shape, and a guide piece 35 having a waveform in a side view is suspended from the center of the upper side thereof in a cantilevered manner. And the convex part 34 of the stopper part 11 is elastically engaged with the hollow 33 of the guide piece 35 in the upper position of the stopper part 11, and the downward movement by the dead weight of the stopper part 11 is prevented.

図11及び図12に示すように、案内部材32の矩形枠の上辺には上側係合部36が後方に突設され、また、矩形枠の下辺から下側係合部37が後方に突設される。これらの上下の係合部36,37は収容室13の底部に形成された上下の係合孔38,39に着脱可能に係合されている。上下の係合部36,37により案内部材32を収容室13に装着するため、案内部材32が安定した状態で収容室13に装着される。   As shown in FIGS. 11 and 12, an upper engaging portion 36 projects rearward from the upper side of the rectangular frame of the guide member 32, and a lower engaging portion 37 projects rearward from the lower side of the rectangular frame. Is done. These upper and lower engaging portions 36 and 37 are detachably engaged with upper and lower engaging holes 38 and 39 formed in the bottom of the storage chamber 13. Since the guide member 32 is mounted in the storage chamber 13 by the upper and lower engaging portions 36 and 37, the guide member 32 is mounted in the storage chamber 13 in a stable state.

以下、片開き蓋体5のロック動作とロック解除動作について説明する。図4は片開き蓋体5のロック状態を示す。図5は蓋体5のロック解除状態と蓋体5の開放状態を示す。また、図10(a)および図11(a)は蓋体5のロック状態を示し、図10(b)および図11(b)は蓋体5のロック解除状態を示す。   Hereinafter, the locking operation and unlocking operation of the single-open lid body 5 will be described. FIG. 4 shows a locked state of the one-sided lid body 5. FIG. 5 shows the unlocked state of the lid 5 and the opened state of the lid 5. 10A and 11A show the locked state of the lid 5, and FIGS. 10B and 11B show the unlocked state of the lid 5.

図4の蓋体5のロック状態では、ストッパ部11が上位置にあり、ロック部材10の係合凹部20にストッパ部11の係合突起21が侵入している状態となる。ストッパ部11の上位置では、ストッパ部11の後面の凸部34が案内部材32の窪み33に弾性的に係合し、ストッパ部11の姿勢を維持する。そのため、ロック部材10の押圧操作部16を後方に押してロック部材10を揺動させようとしても、ロック部材10の係合凹部20の壁面がストッパ部11の係合突起21に当たり、ロック部材10の揺動を規制し、ロック姿勢を維持する。   In the locked state of the lid body 5 in FIG. 4, the stopper portion 11 is in the upper position, and the engagement protrusion 21 of the stopper portion 11 enters the engagement recess 20 of the lock member 10. At the upper position of the stopper portion 11, the convex portion 34 on the rear surface of the stopper portion 11 is elastically engaged with the recess 33 of the guide member 32, and the posture of the stopper portion 11 is maintained. Therefore, even if the pressing member 16 of the locking member 10 is pushed backward to swing the locking member 10, the wall surface of the engaging recess 20 of the locking member 10 hits the engaging protrusion 21 of the stopper 11, and the locking member 10 Control rocking and maintain a locked posture.

このとき、ロック部材10のロック姿勢で、ストッパ部11の係合突起21とロック部材10の係合凹部20との間に寸法精度が異なっていても、これを許容できる隙間23が形成されているので、ストッパ部11の係合突起21とロック部材10の係合凹部20とが、余裕をもった状態で嵌まり合うことになる。このような係合状態であってもロック部材10の回動を十分規制することができるため、高い寸法精度を要求されない利点がある。   At this time, even if the dimensional accuracy is different between the engagement protrusion 21 of the stopper portion 11 and the engagement recess portion 20 of the lock member 10 in the locked posture of the lock member 10, a gap 23 that can allow this is formed. Therefore, the engagement protrusion 21 of the stopper portion 11 and the engagement recess 20 of the lock member 10 are fitted together with a margin. Even in such an engaged state, the rotation of the lock member 10 can be sufficiently restricted, so that there is an advantage that high dimensional accuracy is not required.

ロック部材10のロック姿勢からロック解除するには、ロック部材10の中央窓18を通してストッパ操作部19を操作者の指で下動させる。そうすると、ストッパ部11の下側への操作力により、ストッパ部11の後ろ側にある凸部34が案内部材32の窪み33から外れる。ストッパ部11が下方向へ移動可能となる。ストッパ部11の上下方向への移動長さはストッパ部11の縦穴30の縦方向長さにより決定される。ストッパ部11の上下方向の移動長さを、ロック部材10の中央窓18の上下辺の位置によっても設定することができるが、中央窓18の上下寸法をストッパ部11の上下方向移動長さに合わせて設定しなければならず、両者の寸法精度の相違により、ストッパ部11の上下移動長さが狂う可能性がある。本例のように、ストッパ部11の縦穴30の上下長さにより設定する方が寸法精度の相違に対応しやすいので好ましい。   In order to unlock the lock member 10 from the locked position, the stopper operating portion 19 is moved downward by the operator's finger through the central window 18 of the lock member 10. Then, the convex portion 34 on the rear side of the stopper portion 11 is disengaged from the recess 33 of the guide member 32 by the operation force to the lower side of the stopper portion 11. The stopper portion 11 can move downward. The length of movement of the stopper portion 11 in the vertical direction is determined by the length of the vertical hole 30 in the stopper portion 11. The moving length of the stopper portion 11 in the vertical direction can also be set by the position of the upper and lower sides of the central window 18 of the lock member 10, but the vertical dimension of the central window 18 is set to the vertical moving length of the stopper portion 11. The vertical movement length of the stopper portion 11 may be distorted due to the difference in dimensional accuracy between the two. As in this example, setting according to the vertical length of the vertical hole 30 of the stopper portion 11 is preferable because it can easily cope with a difference in dimensional accuracy.

そして、縦穴30の上端を収容室13のガイド軸31に当たるまでストッパ部11を下動させたとき、ストッパ部11の係合突起21がロック部材10の係合凹部20から外れ、ロック部材10が揺動可能となる。この状態で、ロック部材10の押圧操作部16を後方に押すと、ロック部材10が横軸14周りに揺動し、ロック部材10の上端にある係合爪15が蓋体5の係合部9から外れる。蓋体5のロックが外れると、蓋体5は、図示しないコイルばねの付勢力によりヒンジ軸4の周りに上回動して片開き蓋体5が開放される。   When the stopper portion 11 is moved downward until the upper end of the vertical hole 30 contacts the guide shaft 31 of the storage chamber 13, the engagement protrusion 21 of the stopper portion 11 is disengaged from the engagement recess 20 of the lock member 10, and the lock member 10 is It can swing. When the pressing operation portion 16 of the lock member 10 is pushed rearward in this state, the lock member 10 swings around the horizontal axis 14, and the engagement claw 15 at the upper end of the lock member 10 is engaged with the engagement portion of the lid 5. Deviate from 9. When the lid 5 is unlocked, the lid 5 is rotated upward around the hinge shaft 4 by an urging force of a coil spring (not shown) to open the one-sided lid 5.

以上の通り、本実施形態では、容器本体の口元外周に注出口3cを有する口栓本体3が螺着され、口栓本体3に注出口3cを開閉可能とする蓋体5がヒンジ軸4を介して回動可能に設けられ、蓋体5の回動端を口栓本体3に対して閉姿勢にロック可能なロック機構6が設けられ、このロック機構6は、蓋体5の回動端に設けられた係合部9に係脱可能に係合する係合爪15を上部に備え、下部に押圧操作部16を備え、係合部9を係合爪15に係合するロック姿勢と係合部9を係合爪15から離脱解除するロック解除姿勢との間で横軸14周りに揺動可能なロック部材10と、ロック部材10をロック姿勢において、その揺動を規制するストッパ部11とを備え、ストッパ部11は、口栓本体3のロック部材10よりも内側に配置され、口栓本体3にロック部材10とは独立して上下スライド可能に案内され、ロック部材10には、その上下方向中間位置にストッパ部11を操作可能とする中央窓18が貫通形成され、この中央窓18を通して外側からストッパ部11を操作可能とする操作部19がストッパ部11と一体形成されている。   As described above, in the present embodiment, the cap body 3 having the spout 3 c is screwed to the outer periphery of the mouth of the container body, and the lid 5 that allows the spout 3 c to be opened and closed is connected to the spout body 3. The lock mechanism 6 is provided so as to be pivotable and capable of locking the pivot end of the lid body 5 in a closed position with respect to the plug body 3. A locking posture in which an engaging claw 15 detachably engaged with an engaging portion 9 provided in the upper portion is provided at the upper portion, a pressing operation portion 16 is provided at the lower portion, and the engaging portion 9 is engaged with the engaging claw 15. A lock member 10 that can swing around the horizontal axis 14 between an unlocking posture for releasing the engaging portion 9 from the engaging claw 15 and a stopper portion that restricts the swinging of the locking member 10 in the locked posture. 11, the stopper portion 11 is disposed inside the locking member 10 of the plug body 3, The body 3 is guided so as to be vertically slidable independently of the lock member 10, and a central window 18 through which the stopper portion 11 can be operated is formed in the lock member 10 at an intermediate position in the vertical direction. An operating portion 19 that allows the stopper portion 11 to be operated from the outside is formed integrally with the stopper portion 11.

したがって、ストッパ部11は、口栓本体3においてロック部材10の内側に配置されているので、上下方向にロック部材とストッパ部とが配列されるよりもコンパクト化できる。また、ロック部材10の中央窓18を貫通してストッパ部11の操作部19を設けているので、ロック部材10の外側からストッパ部11を確実に操作することができる。しかも、ストッパ部11の操作部19の下側にロック部材10の押圧操作部16を配置しているので、ストッパ部11の下動によるロック解除からロック部材10の押圧操作部16の押し動作によるロック部材10の揺動に至る一連の動作をワンタッチで行うことができる。   Therefore, since the stopper part 11 is arrange | positioned inside the lock member 10 in the plug main body 3, it can make compact rather than a lock member and a stopper part being arranged in an up-down direction. Moreover, since the operation part 19 of the stopper part 11 is provided through the central window 18 of the lock member 10, the stopper part 11 can be reliably operated from the outside of the lock member 10. In addition, since the pressing operation portion 16 of the lock member 10 is disposed below the operation portion 19 of the stopper portion 11, the unlocking operation by the downward movement of the stopper portion 11 causes the pressing operation of the pressing operation portion 16 of the lock member 10. A series of operations leading to rocking of the lock member 10 can be performed with one touch.

また、ストッパ部11は、ロック部材10とは独立して上下方向に移動可能とされ、すなわち、ロック部材10およびストッパ部11とが独立して動作するため、両者の寸法精度に狂いが生じても、両者が確実に機能する。ストッパ部11をロック部材10とは独立して動作させるため、ストッパ部11の後面の左右両側のスライドレール27が収容室13の底部の左右一対の案内壁28に嵌合されているので、ストッパ部11は、案内壁28に沿って上下方向に確実に案内される。   Further, the stopper portion 11 can be moved in the vertical direction independently of the lock member 10, that is, the lock member 10 and the stopper portion 11 operate independently, resulting in a deviation in the dimensional accuracy of both. But both work reliably. In order to operate the stopper portion 11 independently of the lock member 10, the left and right slide rails 27 on the rear surface of the stopper portion 11 are fitted to the pair of left and right guide walls 28 on the bottom of the storage chamber 13. The part 11 is reliably guided in the vertical direction along the guide wall 28.

また、ストッパ部11は、その上下方向の縦穴30が形成され、縦穴30に口栓本体3側からのガイド軸31が挿入され、ストッパ部11は、縦穴30の上下方向長さ分だけ上下方向に移動可能とされている。そのため、ストッパ部11は、ロック部材10とは独立して口栓本体3に確実に上下方向に移動案内される。   The stopper portion 11 is formed with a vertical hole 30 in the vertical direction, and a guide shaft 31 from the plug body 3 side is inserted into the vertical hole 30. The stopper portion 11 is vertically moved by the vertical length of the vertical hole 30. It is possible to move to. Therefore, the stopper portion 11 is reliably guided to move up and down by the plug body 3 independently of the lock member 10.

また、ストッパ部11の上端にロック部材10をロック姿勢で揺動するのを阻止する係合突起21が突設され、この係合突起21がストッパ部11の上下移動方向の上位置において、ロック部材10の裏面に形成された下開放の係合凹部20に侵入可能とされ、ロック部材10のロック姿勢でかつストッパ部11の上下移動方向の上位置で、係合突起21が係合凹部20に入り込み、ロック部材10を横軸14周りに回動させようとしても係合凹部20の側壁にストッパ部11の係合突起21が当接してロック部材10の揺動を規制する。   Further, an engaging projection 21 is provided at the upper end of the stopper portion 11 to prevent the locking member 10 from swinging in the locking posture. The engaging projection 21 is locked at the upper position in the vertical movement direction of the stopper portion 11. The engaging recess 21 can enter the lower opening engaging recess 20 formed on the back surface of the member 10, and the engaging protrusion 21 is engaged with the engaging recess 20 in the locking position of the locking member 10 and in the upper position in the vertical movement direction of the stopper portion 11. Even if the lock member 10 enters and rotates the lock member 10 around the horizontal axis 14, the engagement protrusion 21 of the stopper portion 11 abuts on the side wall of the engagement recess 20 to restrict the swing of the lock member 10.

このとき、ロック部材10のロック姿勢で、ストッパ部11の係合突起21とロック部材10の係合凹部20との間に寸法精度の違いを許容するための隙間が形成される。すなわち、ストッパ部11の係合突起21とロック部材10の係合凹部20とは余裕をもった寸法で嵌まり合うようにしているので、ロック部材10の揺動を十分規制することができ、高い寸法精度も要求されないという利点がある。   At this time, a gap for allowing a difference in dimensional accuracy is formed between the engagement protrusion 21 of the stopper portion 11 and the engagement recess 20 of the lock member 10 in the locked posture of the lock member 10. That is, since the engagement protrusion 21 of the stopper portion 11 and the engagement recess 20 of the lock member 10 are fitted with a margin, the swing of the lock member 10 can be sufficiently restricted, There is an advantage that high dimensional accuracy is not required.

さらに、ストッパ部11を上下移動方向の上位置において、その上姿勢を維持するためのストッパ部案内部材32が口栓本体3の収容室13に設けられ、案内部材32にはストッパ部11の後端と案内部材32とのうちのいずれか一方に形成された窪みと、他方に形成され前記窪みに弾性的に接触する凸部とを備え、ストッパ部11を上姿勢に維持してロック部材10のロック姿勢を維持できる態様になっている。このとき、ストッパ部と口栓本体のいずれか一方の窪み33と他方の凸部34とが弾性的に接触する態様になっているので、ストッパ部11を確実にロック姿勢に維持することができる。   Further, a stopper guide member 32 for maintaining the stopper portion 11 in the upper position in the vertical movement direction is provided in the storage chamber 13 of the plug body 3, and the guide member 32 is provided behind the stopper portion 11. The lock member 10 includes a recess formed in one of the end and the guide member 32 and a convex portion formed on the other and elastically contacting the recess, and the stopper portion 11 is maintained in an upward position. The lock posture can be maintained. At this time, since either one of the stopper portion and the plug main body has a recess 33 and the other convex portion 34 are in elastic contact with each other, the stopper portion 11 can be reliably maintained in the locked posture. .

また、ストッパ部案内部材32の裏面の上下部には口栓本体3に係合するための係合部36,37が形成され、案内部材32が口栓本体3の係合孔38,39に着脱可能に嵌めこまれている。案内部材32を口栓本体3と一体形成することも可能であるが、案内部材32の窪み33あるいは凸部34の成形を考慮すれば、案内部材32を口栓本体3と別体で形成し、成形した案内部材32を口栓本体3の係合孔38,39に着脱可能に嵌めこむ構成の方が成形上有利である。また、案内部材32は、上下の係合部36,37が収容室13の上下の係合孔38,39に係合する態様としているので、案内部材32は安定した状態で収容室13に装着することができる。   In addition, engaging portions 36 and 37 for engaging with the plug body 3 are formed on the upper and lower portions of the back surface of the stopper guide member 32, and the guide member 32 is formed in the engagement holes 38 and 39 of the plug body 3. Removably fitted. Although the guide member 32 can be formed integrally with the plug body 3, the guide member 32 is formed separately from the plug body 3 in consideration of the formation of the recess 33 or the convex portion 34 of the guide member 32. A configuration in which the molded guide member 32 is detachably fitted into the engagement holes 38 and 39 of the plug body 3 is more advantageous in terms of molding. Further, since the guide member 32 is configured such that the upper and lower engaging portions 36 and 37 engage with the upper and lower engagement holes 38 and 39 of the storage chamber 13, the guide member 32 is mounted in the storage chamber 13 in a stable state. can do.

さらに、口栓本体3の蓋体回動端側(前端側)に保護壁12が形成され、この保護壁12に囲まれて収容室13が形成され、この収容室13にロック機構6が収容されているので、ロック機構6の各部材10,11,19、32等が操作者の手指に不用意に当たって、その姿勢が変わるのを防止することができる。   Further, a protective wall 12 is formed on the lid rotating end side (front end side) of the plug body 3, and a storage chamber 13 is formed surrounded by the protective wall 12, and the lock mechanism 6 is stored in the storage chamber 13. Therefore, the members 10, 11, 19, 32, etc. of the lock mechanism 6 can be prevented from inadvertently hitting the fingers of the operator and changing their postures.

このとき、ストッパ部11を操作する操作部19を保護壁12の高さよりも低く形成し、保護壁12から後退した位置に配置することができる。これにより、操作者の手指が不用意に操作部19に当たり、ストッパ部11を動作させるのを防止することができる。   At this time, the operation portion 19 for operating the stopper portion 11 can be formed lower than the height of the protective wall 12 and can be disposed at a position retracted from the protective wall 12. Accordingly, it is possible to prevent the operator's fingers from inadvertently hitting the operation unit 19 and operating the stopper unit 11.

また、ロック部材10は、横軸14よりも上端側に係合爪15を備え、横軸14よりも下方の表面側をロック部材10を押圧する押圧操作部16とされ、この押圧操作部16の裏面側と口栓本体3の収容室13の底壁との間に、ロック部材10を係合爪15の係合方向に付勢する付勢バネ26が介在されているので、ロック部材10は付勢バネ26により常にロック姿勢側に付勢されて、ロック姿勢を維持することができる。   The locking member 10 includes an engaging claw 15 on the upper end side of the horizontal shaft 14, and serves as a pressing operation unit 16 that presses the locking member 10 on the surface side below the horizontal shaft 14. Since the biasing spring 26 that biases the lock member 10 in the engagement direction of the engagement claw 15 is interposed between the back surface side of the plug body 3 and the bottom wall of the accommodation chamber 13 of the plug body 3, the lock member 10 Is always urged toward the lock posture by the urging spring 26, so that the lock posture can be maintained.

また、蓋体5を開放方向に付勢するバネ(図示せず)がヒンジ軸4に設けられているので、蓋体5はロック機構6が解除されれば、バネにより開放側に回動し、口栓本体3の注出口3aを露出させ、ワンタッチの操作でボトル本体内の飲料を飲むことができる。   Further, since a spring (not shown) for biasing the lid 5 in the opening direction is provided on the hinge shaft 4, the lid 5 is rotated to the opening side by the spring when the lock mechanism 6 is released. The spout 3a of the cap body 3 can be exposed, and the beverage in the bottle body can be drunk with a one-touch operation.

なお、本考案は上記実施形態に限定されるものではなく、本考案の範囲内で多くの修正・変更を加えることができる。例えば、上記実施形態では、ストッパ部の態様として、ロック部材10側に係合凹部20を、ストッパ部11側に係合突起21を配置した例を示したが、これに限らず、係合凹部20をストッパ部側に、係合突起21をロック部材10側に配置してもよい。   In addition, this invention is not limited to the said embodiment, Many corrections and changes can be added within the scope of the present invention. For example, in the above-described embodiment, an example in which the engagement recess 20 is disposed on the lock member 10 side and the engagement protrusion 21 is disposed on the stopper portion 11 side is shown as an aspect of the stopper portion. 20 may be disposed on the stopper portion side, and the engaging protrusion 21 may be disposed on the lock member 10 side.

また、上記実施形態では保護壁をロック機構の全周に設けた態様を例示したが、保護壁は、全周に設ける態様に限らず、一部に設ける態様、あるいは全く設けない態様等、種々の態様を採用することができる。また、本実施形態では、口栓本体3に筒状の注出口3aを突出した態様を例示したが、これに限らず、注出口は口栓本体3の天面凹部に形成された樋状のものであってもよい。さらに、上記実施形態では、2リットル飲料容器を例示したが、これに限らず、取手を有しない500ミリリットルの飲料容器であってもよいことは勿論である。   Moreover, although the aspect which provided the protective wall in the perimeter of the locking mechanism was illustrated in the said embodiment, a protective wall is not limited to the aspect provided in a perimeter, Various aspects, such as an aspect provided in part or an aspect which does not provide at all. The aspect of this can be employ | adopted. Moreover, in this embodiment, although the aspect which protruded the cylindrical spout 3a in the plug main body 3 was illustrated, not only this but a spout is the bowl-shaped formed in the top | upper surface recessed part of the plug main body 3. It may be a thing. Furthermore, in the said embodiment, although the 2 liter drink container was illustrated, it is needless to say that it is not restricted to this and may be a 500 ml drink container without a handle.
