Description

本発明は、栓本体に蓋体をヒンジ結合した飲料用容器の栓体ヒンジ構造に関するものである。   The present invention relates to a stopper hinge structure of a beverage container in which a lid is hinged to a stopper body.

従来、この種の飲料用容器の栓体として、容器本体の上部開口に被着される栓体と、該栓体にヒンジにて開閉可能に連結され、前記栓体の天板に開口する注出口を液密に覆う蓋体とを備え、前記ヒンジと反対側に前記蓋体の全閉状態を保持するロック手段を備え、前記蓋体のヒンジ側に一体に設けられた係止片が、飲料を飲む際に蓋体が邪魔にならないように該蓋体の全開状態で前記栓体のヒンジに設けられた突起に係止することで全開状態を保持するもの（例えば特許文献１）があるが、係止片が合成樹脂製の蓋体と一体に形成されているので十分な弾性を得るためには強度が劣り、また、成形時の反りや変形により係止が安定しにくい面もあった。   Conventionally, as a stopper of this type of beverage container, a stopper attached to the upper opening of the container body and a hinge that can be opened and closed by a hinge are connected to the top of the stopper. A lid that liquid-tightly covers the outlet, a locking means that holds the fully closed state of the lid on the side opposite to the hinge, and a locking piece that is integrally provided on the hinge side of the lid, There is one that holds the fully open state by engaging the protrusion provided on the hinge of the plug body in the fully opened state so that the cover body does not get in the way when drinking beverages (for example, Patent Document 1). However, since the locking piece is formed integrally with the lid made of synthetic resin, the strength is inferior to obtain sufficient elasticity, and there is also a surface where locking is difficult to stabilize due to warpage and deformation during molding. It was.

また、閉じ状態にて、ばねでロック位置を保つように付勢されたロック部材により閉じ位置に自動的にロックされる蓋体とを備え、蓋体の開き動作の少なくとも終期にロック部材とばねにより蓋体の開閉動作を制動するようにしたロック構造（例えば特許文献２）があり、この蓋体係止構造では、蓋体内部に設けられたバネとスライド動作するロック部材により安定して係止される構造となっているが、そもそも蓋体のロック構造を蓋体天面に配置する必要があり、意匠に関する自由度が失われてしまう。   And a lid that is automatically locked in the closed position by a lock member that is biased so as to maintain the locked position by the spring in the closed state, and at least at the end of the opening operation of the lid, the lock member and the spring There is a lock structure (for example, Patent Document 2) that brakes the opening / closing operation of the lid by means of this, and in this lid locking structure, a spring provided inside the lid and a locking member that slides are stably engaged. Although it is a structure to be stopped, it is necessary to arrange the lock structure of the lid body on the top surface of the lid body in the first place, and the degree of freedom regarding the design is lost.

また、栓体のヒンジ構造とは技術分野が異なるが、電気機器類においてカムを用いたヒンジ構造（例えば特許文献３及び４）が開示されおり、これらカムを用いて回動トルクを制御するものでは、ヒンジがユニット化されており、飲料用容器の栓体に適用するには部品点数が多くなり、コンパクト化を阻害してしまうことが予想される。   Moreover, although the technical field is different from the hinge structure of the plug body, a hinge structure using a cam (for example, Patent Documents 3 and 4) is disclosed in electrical equipment, and the rotational torque is controlled using these cams. Then, since the hinge is unitized, it is expected that the number of parts increases to be applied to the stopper of a beverage container, and the compactness is hindered.

次に、ロック部材16のロック係合部115の上縁が前記栓本体係合部101の下部に係止した状態で、ロック部材16の回動を規制し、係止状態を保持する安全ストッパ121について詳述する。   Next, in a state where the upper edge of the lock engagement portion 115 of the lock member 16 is engaged with the lower portion of the stopper main body engagement portion 101, the safety stopper that restricts the rotation of the lock member 16 and maintains the engagement state. 121 will be described in detail.

図１９などに示すように、安全ストッパ121は、左右のアーム部111，111の間隔に対応した左右幅を有する略矩形の前面板122を備え、この前面板122は、その後面が前記左右の垂直壁105，105の前縁に沿って昇降する。そして、前面板122の後面下部が前記ロック係合部115の前面115Ａに位置することにより、ロック部材16の前側への回動を規制し、ロック係合部115を栓本体係合部101から外すことができなくなる。即ち、ロック部材16を回動しようとすると、前面板122の後面下部に係合部115の前面115Ａが当たり、回動することができず、その前面板122の後面下部がロック部材16の回動を規制する規制部123である。   As shown in FIG. 19 and the like, the safety stopper 121 includes a substantially rectangular front plate 122 having a left and right width corresponding to the distance between the left and right arm portions 111, 111. It moves up and down along the front edges of the vertical walls 105 and 105. The lower portion of the rear surface of the front plate 122 is positioned on the front surface 115A of the lock engaging portion 115, thereby restricting the locking member 16 from rotating to the front side. It cannot be removed. That is, when trying to rotate the lock member 16, the front surface 115 A of the engaging portion 115 hits the lower rear surface of the front plate 122 and cannot rotate, and the lower rear surface of the front plate 122 is not rotated by the lock member 16. It is a regulation unit 123 that regulates movement.

安全ストッパ121を昇降する昇降機構124として、前記左右の垂直壁105，105の内側にレール109，109を縦設し、これら左右のレール109，109に摺動するガイド溝125，125を安全ストッパ121に設けている。具体的には、前面板122の後面の左右に間隔をおいて突出部126，126を設け、これら突出部126，126の外側に、前記ガイド溝125，125を縦設している。また、前記左右の突出部126，126には下面部127，127を設け、この下面部127に下向き筒部128を突設し、この下向き筒部128に付勢手段たる圧縮コイルスプリング129の上端を装着している。一方、図２１に示すように、蓋体12の前部には、前記平坦面72Ｈ及び垂直壁105と一体に底壁部110を設け、この底壁部110に上向き筒部128Ａを突設し、この上向き筒部128Ａに前記圧縮コイルスプリング129の下端を装着する。   As an elevating mechanism 124 for elevating and lowering the safety stopper 121, rails 109 and 109 are vertically provided inside the left and right vertical walls 105 and 105, and guide grooves 125 and 125 sliding on the left and right rails 109 and 109 are provided as safety stoppers. 121. Specifically, projecting portions 126, 126 are provided on the left and right sides of the rear surface of the front plate 122, and the guide grooves 125, 125 are vertically provided outside the projecting portions 126, 126. Further, the left and right projecting portions 126, 126 are provided with lower surface portions 127, 127, and downward cylindrical portions 128 project from the lower surface portion 127, and the upper ends of compression coil springs 129 serving as biasing means for the downward cylindrical portions 128 are provided. Wearing. On the other hand, as shown in FIG. 21, a bottom wall portion 110 is provided integrally with the flat surface 72H and the vertical wall 105 at the front portion of the lid body 12, and an upward cylindrical portion 128A is projected from the bottom wall portion 110. The lower end of the compression coil spring 129 is attached to the upward cylindrical portion 128A.

前記前面板122の後面中央には、弾性係止部たる弾性爪片131が設けられている。この弾性爪片131は、前後方向の横片部132Ｙの後部に下向きの縦片部132Ｔを設け、この縦片部132Ｔの後端後部に係止部たる爪部133を設け、この爪部133は前記下向き面103に係止する斜めの規制係止部133Ａと、この係止部133Ａ位置より先端側に設けられた斜めの案内部133Ｂとが形成されている。そして、規制係止部133Ａが後側に向って低くなるように傾斜した面であり、案内部133Ｂは後側に向って高くなるように傾斜した面であり、水平に対する角度は前記規制係止部133Ａに比べて案内部133Ｂが大きい。   At the center of the rear surface of the front plate 122, an elastic claw piece 131 as an elastic locking portion is provided. This elastic claw piece 131 is provided with a downward vertical piece 132T at the rear part of the horizontal piece part 132Y in the front-rear direction, and a claw part 133 as a locking part is provided at the rear end of the vertical piece part 132T. Is formed with an oblique regulation locking portion 133A that is locked to the downward surface 103, and an oblique guide portion 133B that is provided on the tip side from the position of the locking portion 133A. The restriction locking portion 133A is a surface inclined so as to become lower toward the rear side, and the guide portion 133B is a surface inclined so as to become higher toward the rear side. The guide part 133B is larger than the part 133A.

そして、図４に示すように、爪部133の規制係止部133Ａが下向き係合面103に係止した位置で、安全ストッパ121の規制部123が前記ロック部材16のロック係合部115の前方に位置し、この位置がロック部材16の動きを規制する位置である。一方、この規制位置から安全ストッパ121を上側に移動し、爪部133と下向き係合面103との係止が解除された位置で、前記ロック部材16が回動可能となる。尚、ロック部材16の前面板122の上部外面には、左右方向に操作部130が前方に膨出形成されている。   Then, as shown in FIG. 4, the restricting portion 123 of the safety stopper 121 is connected to the lock engaging portion 115 of the lock member 16 at a position where the restricting engaging portion 133 </ b> A of the claw portion 133 is engaged with the downward engaging surface 103. It is located forward, and this position is a position that restricts the movement of the lock member 16. On the other hand, the safety stopper 121 is moved upward from the restricted position, and the lock member 16 can be rotated at a position where the engagement between the claw portion 133 and the downward engagement surface 103 is released. An operation portion 130 is formed to bulge forward in the left-right direction on the upper outer surface of the front plate 122 of the lock member 16.

図１８などに示すように、前記安全ストッパ121を垂直壁105，105間に装着した後、前記嵌合軸106に装着するカバー部材135を備える。尚、少なくとも安全ストッパ121がカバー部材135に当たる位置でロック部材16の回動規制は解除されている。カバー部材135は前記左右の垂直壁105，105間に挿入可能な左右幅を有する。また、カバー部材135には前記嵌合軸106を挿通する挿通孔136が穿設され、カバー部材135の前上角部には湾曲面135Ｗが形成され、この湾曲面135Ｗは前記垂直壁105の前上角部の湾曲面105Ｗと略同一に形成されている。尚、図１８に示すように、カバー部材135の後面135Ｂは平坦面に形成され、蓋体12の垂直壁105，105間の平坦面72Ｈに係合して回り止め状態で取り付けられる。   As shown in FIG. 18 and the like, the safety stopper 121 is mounted between the vertical walls 105 and 105, and then the cover member 135 is mounted on the fitting shaft 106. The rotation restriction of the lock member 16 is released at least at a position where the safety stopper 121 hits the cover member 135. The cover member 135 has a left and right width that can be inserted between the left and right vertical walls 105 and 105. Further, the cover member 135 is formed with an insertion hole 136 through which the fitting shaft 106 is inserted, and a curved surface 135W is formed at a front upper corner portion of the cover member 135. The curved surface 135W is formed on the vertical wall 105. It is formed substantially the same as the curved surface 105W at the front upper corner. As shown in FIG. 18, the rear surface 135B of the cover member 135 is formed as a flat surface, and is engaged with the flat surface 72H between the vertical walls 105, 105 of the lid 12 and attached in a detent state.

前記ロック機構100の製造においては、上方から安全ストッパ121を垂直壁105，105の間に挿入すると共に、安全ストッパ121と底壁部110との間に圧縮コイルスプリング129を配置し、この後、上方からカバー部材135を垂直壁105，105の間に挿入すると共に、左右の垂直壁105，105を挟むようにロック部材16を配置し、ロック部材16の遊挿孔111Ｈと垂直壁105の軸孔105Ｈとカバー部材135の挿通孔136に嵌合軸106を挿入配置することにより、蓋体12に安全ストッパ121とカバー部材135とロック部材16が取り付けられる。つまり安全ストッパ121の抜け止めを担うカバー部材135と、ロック部材16の取り付けを嵌合軸106のみで行うことができる。   In the manufacture of the locking mechanism 100, the safety stopper 121 is inserted between the vertical walls 105, 105 from above, and the compression coil spring 129 is disposed between the safety stopper 121 and the bottom wall portion 110. The cover member 135 is inserted between the vertical walls 105 and 105 from above, and the lock member 16 is disposed so as to sandwich the left and right vertical walls 105 and 105. The loose insertion hole 111H of the lock member 16 and the axis of the vertical wall 105 The safety stopper 121, the cover member 135, and the lock member 16 are attached to the lid body 12 by inserting the fitting shaft 106 into the hole 105 </ b> H and the insertion hole 136 of the cover member 135. That is, the cover member 135 for holding the safety stopper 121 and the lock member 16 can be attached only by the fitting shaft 106.

そして、安全ストッパ121を押下げると、圧縮コイルスプリング129が圧縮されると共に、弾性爪片131が弾性変形して外観カバー14の下向き面103に弾性爪片131の規制係止部133Ａが係止する。これにより安全ストッパ121が固定され、安全ストッパ121の規制部123がロック係合部115の前方に位置し、ロック部材16の動きが規制され、ロック機構100によるロックがなせれる。   When the safety stopper 121 is pushed down, the compression coil spring 129 is compressed, and the elastic claw piece 131 is elastically deformed, so that the regulation locking portion 133A of the elastic claw piece 131 is locked to the downward surface 103 of the exterior cover 14. To do. As a result, the safety stopper 121 is fixed, the restriction portion 123 of the safety stopper 121 is positioned in front of the lock engagement portion 115, the movement of the lock member 16 is restricted, and the lock mechanism 100 can be locked.

一方、操作部130を用いて安全ストッパ121を押し上げると、弾性爪片131が弾性変形して下向き面103から爪部133が外れ、圧縮コイルスプリング129の付勢により安全ストッパ121が上昇し、カバー部材135に当接して停止し、安全ストッパ121がロック部材16の動きを規制しない位置に保持される（図５）。このため誤って安全ストッパ121がロック部材16の動きを規制することがない。   On the other hand, when the safety stopper 121 is pushed up using the operation unit 130, the elastic claw piece 131 is elastically deformed and the claw part 133 is detached from the downward surface 103, and the safety stopper 121 is lifted by the bias of the compression coil spring 129, and the cover The safety stopper 121 is held at a position where the movement of the lock member 16 is not restricted (FIG. 5). For this reason, the safety stopper 121 does not restrict the movement of the lock member 16 by mistake.

安全ストッパ121を昇降して爪部133を下向き面103に係脱する場合、水平に対する角度が規制係止部133Ａに比べて案内部133Ｂが大きいため、安全ストッパ121を下げる際は、案内部133Ｂによりスムーズに爪部133が下向き面103に係止し、且つ確実に係止し、一方、安全ストッパ121を上げる際には、下げる場合よりも、抵抗が大きく、所定のクリック感が得られる。   When the safety stopper 121 is moved up and down to engage and disengage the claw portion 133 with the downward surface 103, the guide portion 133B has a larger angle with respect to the horizontal than the restriction locking portion 133A. As a result, the claw portion 133 is smoothly and securely locked to the downward surface 103. On the other hand, when the safety stopper 121 is raised, the resistance is larger than when it is lowered, and a predetermined click feeling is obtained.

次に、前記飲料用容器の使用方法について説明する。容器本体２内に飲料を入れる際には、栓体３を回転し、容器本体２の雌螺子部24から栓本体11の中栓本体13の雄螺子部23を外すことにより、容器本体２から栓本体11を取り外し、大きく開いた開口端部２Ａから内部に飲料を入れることができる。飲料を入れた後、容器本体２の雌螺子部24に栓本体11の中栓本体13の雄螺子部23を螺合することにより、容器本体２に栓体３を取り付けることができる。 Next, a method for using the beverage container will be described. When the beverage is put into the container main body 2, the plug body 3 is rotated, and the male screw part 23 of the middle plug main body 13 of the plug main body 11 is removed from the female screw part 24 of the container main body 2. Remove the plug body 11, it is possible to put a beverage therein from gaping apertures end 2A. After the beverage is put, the plug body 3 can be attached to the container body 2 by screwing the male screw section 23 of the plug body 11 into the female thread section 24 of the container body 2.

したがって、外観カバー14のみを容器本体２に取り付けることはできず、中栓本体13を取付忘れを防止できる。また、取付状態で、図７に示したように、円筒部51の下縁部51Ｆが容器本体２の縮小部５Ｓに当接して開口端部２Ａ下部の外側を円筒部51が覆い、この当接状態で、後側は、前記凹部62の後壁部62Ｂ後方の上面部62Ｊの下面と、開口端部２Ａとの間には隙間52Ｓが形成され、前側は、外観カバー側係合部55などと開口端部２Ａとの間に隙間が形成され、このように開口端部２Ａは外観カバー14には接触していない。尚、その上面部62Ｊの後部上面に前記後開口部53Ｂの底部53Ｔが設けられている。   Therefore, it is not possible to attach only the appearance cover 14 to the container main body 2, and forgetting to attach the inner plug main body 13 can be prevented. Further, in the mounted state, as shown in FIG. 7, the lower edge portion 51F of the cylindrical portion 51 abuts on the reduced portion 5S of the container body 2, and the cylindrical portion 51 covers the outside of the lower portion of the opening end portion 2A. In the contact state, a gap 52S is formed between the lower surface of the upper surface portion 62J behind the rear wall portion 62B of the recess 62 and the opening end portion 2A in the rear side, and the outer cover side engaging portion 55 is disposed on the front side. And the opening end 2A are formed, and thus the opening end 2A is not in contact with the external cover 14. A bottom 53T of the rear opening 53B is provided on the rear upper surface of the upper surface 62J.

閉成状態の蓋体12は、ロック機構100によりロックすることにより、誤って開くことがなく、開く場合は、操作部130により安全ストッパ121を上方に移動し、係止受部たる下向き面103と係止部たる爪部133の係止を解除する。   The lid 12 in the closed state is not accidentally opened by being locked by the lock mechanism 100. In the case of opening, the safety stopper 121 is moved upward by the operation unit 130, and the downward facing surface 103 serving as the latch receiving unit is used. And the latching of the nail | claw part 133 which is a latching part is cancelled | released.

この解除によりロック部材16が操作可能となり、図５に示すように、指掛け部114に指を掛け、ロック部材16の連結部112を斜め前上方向に引き上げると、ロック部材16の左右のアーム部111，111間が僅かに開くように弾性変形し、栓本体係合部101の下からロック部材16のロック係合部115が外れ、簡単に蓋体12を開くことができる。したがって、従来のシーソー式のロック部材のように押すなど操作が不要となり、ロック部材16を手前に引いて持ち上げるという操作により簡便に蓋体12を開くことができる。しかも、栓体３にはロック部材を押す操作に必要なスペースが不要となる。   As a result of this release, the lock member 16 can be operated. As shown in FIG. 5, when the finger is hooked on the finger hook portion 114 and the connecting portion 112 of the lock member 16 is lifted obliquely upward, the left and right arm portions of the lock member 16 It is elastically deformed so that the space between 111 and 111 is slightly opened, the lock engaging portion 115 of the lock member 16 is removed from under the stopper main body engaging portion 101, and the lid 12 can be easily opened. Therefore, an operation such as pushing like a conventional seesaw type lock member is not required, and the lid 12 can be easily opened by an operation of pulling the lock member 16 forward and lifting it. In addition, the plug body 3 does not require a space necessary for the operation of pushing the lock member.

さらに、蓋体12を開くと、クリック突起90がクリック部92を乗り越える際にクリック感が得られ、開成位置凹所91Ａにクリック突起90が係合し、蓋体12が全開となる。蓋体12を開くと、図８に示すように、飲み口25が大きく現れ、この飲み口25に口をつけて内部の飲料を飲んだり、飲み口25から飲料を他の容器に注いだりすることができる。この場合、開成位置凹所91Ａにクリック突起90が係合しており、蓋体12が開成位置に保持されるため、飲んだり、注いだりする際に蓋体12が閉まることなく、蓋体12が邪魔になることがない。この場合、少なくとも、蓋体12の自重ではクリック突起90がクリック部92を乗り越えることがないように、圧縮コイルスプリング87の付勢力を設定している。   Further, when the lid 12 is opened, a click feeling is obtained when the click projection 90 gets over the click portion 92, the click projection 90 is engaged with the open position recess 91A, and the lid 12 is fully opened. When the lid 12 is opened, as shown in FIG. 8, the drinking mouth 25 appears large, and the inside of the drinking mouth 25 is put to drink a beverage inside, or the beverage is poured from the drinking mouth 25 into another container. be able to. In this case, since the click protrusion 90 is engaged with the open position recess 91A and the lid body 12 is held in the open position, the lid body 12 does not close when drinking or pouring, and the lid body 12 is not closed. Will not get in the way. In this case, the urging force of the compression coil spring 87 is set so that the click protrusion 90 does not get over the click portion 92 at least by the dead weight of the lid body 12.

一方、閉成位置の蓋体12を閉める方向に回動し、蓋体12を閉める方向に所定以上の力を加えると、クリック部92をクリック突起90が乗り越えることができる。蓋体12を開いた状態では、図６に示すように、安全ストッパ121は圧縮コイルスプリング129により上方に位置する。この位置はロック部材16の動きを規制しない位置であり、図６の位置から蓋体12を下方に回動すると、栓本体係合部101に連結部112の後面が当接し、連結部112が前側に移動するようにロック部材16が回動し、連結部112が栓本体係合部101が通過すると、栓本体係合部101の下にロック係合部115が係止する。この場合も、蓋体12を開く際と同様に、ロック部材16は、前記通過時にアーム部111，111が開くように弾性変形し、通過後、弾性復元力により復帰し、これらの動作は連続したワンアクションにより行われる。   On the other hand, when the cover body 12 in the closed position is rotated in the closing direction and a predetermined force or more is applied in the closing direction, the click projection 92 can get over the click projection 92. In the state where the lid 12 is opened, the safety stopper 121 is positioned above by the compression coil spring 129 as shown in FIG. This position is a position where the movement of the lock member 16 is not restricted. When the lid body 12 is rotated downward from the position shown in FIG. 6, the rear surface of the connecting portion 112 comes into contact with the plug body engaging portion 101, and the connecting portion 112 is When the lock member 16 is rotated so as to move to the front side and the plug main body engaging portion 101 passes through the connecting portion 112, the lock engaging portion 115 is locked under the plug main body engaging portion 101. Also in this case, similarly to when the lid 12 is opened, the lock member 16 is elastically deformed so that the arm portions 111 and 111 are opened at the time of the passage, and after the passage, the lock member 16 is restored by the elastic restoring force. It is done by one action.

このようにして栓本体係合部101にロック係合部115が係止した後、安全ストッパ121を下げ、下向き面103に爪部133が係止すると、安全ストッパ121の規制部123がロック係合部115の前に位置し、この位置が安全ストッパ121によりロック部材16の動作を規制する位置であり、ロック部材16に接触してもロックが解除されることがない。このように安全ストッパ121は蓋体12が閉成位置にある場合のみにロック部材16の動作を規制する位置に保持されるものであり、開成位置の蓋体12を閉める際には安全ストッパ121はロック部材16の作動を規制する位置に保持できないため、誤操作を防止できる。 After the lock engaging portion 115 is locked to the stopper main body engaging portion 101 in this way, the safety stopper 121 is lowered, and when the claw portion 133 is locked to the downward surface 103, the regulating portion 123 of the safety stopper 121 is locked. It is located in front of the joint portion 115, and this position is a position where the operation of the lock member 16 is restricted by the safety stopper 121. Even if the lock member 16 is touched, the lock is not released. Thus, the safety stopper 121 is held at a position that restricts the operation of the lock member 16 only when the lid 12 is in the closed position. When the lid 12 in the opened position is closed, the safety stopper 121 is held. Since the lock member 16 cannot be held at a position where the operation of the lock member 16 is restricted, erroneous operation can be prevented.

栓体３を洗浄する際には、容器本体２から栓体３を取り外し、蓋体12を開くと、図８に示すように、外観カバー14内の後部に、外観カバー側係合部材61の操作部65が現れる。この操作部65は、外観カバー14の上面部52から離れた内部にあり、通常の使用では操作部65に接触することはない。一方、分解する際は、操作部65を略水平方向で後側に押してやれば、外観カバー側係合部材61の係合部67から、中栓本体13の栓本体側係合受部41が外れ、中栓本体13の前側が係合した状態で、この係合箇所を中心に中栓本体13の後側を回動するようにして外観カバー14内から中栓本体13を取り外すことができる。   When the stopper 3 is washed, when the stopper 3 is removed from the container body 2 and the lid 12 is opened, the outer cover side engaging member 61 is disposed at the rear portion of the outer cover 14 as shown in FIG. The operation unit 65 appears. The operation unit 65 is located inside the outer cover 14 away from the upper surface 52, and does not come into contact with the operation unit 65 in normal use. On the other hand, when disassembling, if the operation portion 65 is pushed rearward in a substantially horizontal direction, the plug body side engagement receiving portion 41 of the inner plug body 13 is moved from the engagement portion 67 of the external cover side engagement member 61. The inner plug main body 13 can be removed from the exterior cover 14 by rotating the rear side of the inner plug main body 13 around the engaging portion in a state where the front side of the inner plug main body 13 is engaged. .

このようにして取り外した中栓本体13には、係合部材61などの可動部分がないため、洗浄し易いものとなる。また、中栓本体13の前側も、凹みではなく、突起状の栓本体側係合部35が設けられているから、洗浄し易い。   The inner plug main body 13 removed in this way has no movable parts such as the engaging member 61, so that it becomes easy to clean. In addition, the front side of the inner plug main body 13 is not recessed, but is provided with a protruding plug main body side engaging portion 35, so that it is easy to clean.

また、分解して洗浄した後は、外観カバー14の下側から外観カバー側係合部55の上に栓本体側係合部35を載置するように、外観カバー側係合部55内に栓本体側係合部35を係入し、外観カバー側係合部55を略中心として、中栓本体13の後側が上側に回転すると、栓本体側係合受部41の傾斜面42が係合部材61の傾斜案内面67Ｂに当接し、係合部材61が後退し、傾斜部42が傾斜案内面67Ｂを通過すると、圧縮コイルスプリング69の弾性復元力により係合部材61が前進し、栓本体側係合受部41が係合部材61の係合部67に係止した嵌合状態が得られ、外観カバー14に中栓本体13を簡便に取り付けることができる。   Further, after disassembling and cleaning, the stopper main body side engaging portion 35 is placed in the outer cover side engaging portion 55 from the lower side of the outer cover 14 on the outer cover side engaging portion 55. When the plug main body side engaging portion 35 is engaged and the rear side of the inner plug main body 13 is rotated upward about the outer cover side engaging portion 55 as the center, the inclined surface 42 of the plug main body side engaging receiving portion 41 is engaged.
