この考案は、携帯用魔法瓶や水筒等の携帯用飲料容器に採用されている、容器本体に装着される口栓部材にヒンジを介して蓋部材が開閉可能に取り付けられた、直飲みタイプの飲料容器の栓体に関する。   This device is used in portable beverage containers such as portable thermos bottles and water bottles, and is a direct-drinking type beverage in which a lid member is attached to a cap member attached to the container body via a hinge so as to be opened and closed. The present invention relates to a container stopper.

この種の栓体としては、例えば、特開２０１５−９８３５２号公報に開示されたものがある。この栓体は、図１４及び図１５に示すように、容器本体６１に装着される口栓部材６２と、この口栓部材６２の後部にヒンジを介して片開き可能に取り付けられた蓋部材６５とを備えており、口栓部材６２は、容器本体６１の口部に螺着されるベース部材６３と、ベース部材６３に着脱自在に取り付けられる口部材６４とを有している。   An example of this type of plug is disclosed in JP-A-2015-98352. As shown in FIGS. 14 and 15, the plug body includes a plug member 62 attached to the container main body 61 and a lid member 65 attached to the rear part of the plug member 62 so as to be able to be opened one by one via a hinge. The plug member 62 includes a base member 63 that is screwed into the mouth portion of the container main body 61 and a mouth member 64 that is detachably attached to the base member 63.

前記ベース部材６３の内面側には、前後に第１の係止部６３ａ及び第２の係止部６３ｂがそれぞれ形成されており、口部材６４の外面側には、第１の係止部６３ａ及び第２の係止部６３ｂにそれぞれ係合することで口部材６４をベース部材６３に固定する第１の被係止部６４ａ及び第２の被係止部６４ｂが形成されている。   A first locking portion 63a and a second locking portion 63b are formed on the inner surface side of the base member 63 on the front and rear sides, respectively, and on the outer surface side of the mouth member 64, the first locking portion 63a. And the 1st to-be-latched part 64a and the 2nd to-be-latched part 64b which fix the opening | mouth member 64 to the base member 63 by engaging with the 2nd latching | locking part 63b are formed.

図１６（ａ）に実線で示すように、ベース部材６３の下方から口部材６４を内側へ挿し入れ、同図に二点鎖線で示すように、口部材６４を傾けるように回動させることで、第１の被係止部６４ａが第１の係止部６３ａの上側に、第２の被係止部６４ｂが第２の係止部６３ｂの下方に配置された状態とした後、口部材６４の傾きを無くす起回動操作を行うと、同図（ｂ）に示すように、第２の被係止部６４ｂが、第２の係止部６３ｂを下から上へ乗り越え、第１の被係止部６４ａ及び第２の被係止部６４ｂが第１の係止部６３ａ及び第２の係止部６３ｂにそれぞれ係合して口部材６４がベース部材６３に取り付けられる。   As shown by a solid line in FIG. 16A, the mouth member 64 is inserted inward from below the base member 63, and the mouth member 64 is rotated so as to be inclined as shown by a two-dot chain line in FIG.

The operation button 18 can be fitted into a third locking portion 11c provided on the base member 11. Has a third locked portion 18a projecting rearward.

前記弾性部材１９は、シリコンゴムによって形成された有底筒状であり、操作ボタン１８の下端から下方側に突出して嵌合凹部１２ｃの底面に当接するように操作ボタン１８に取り付けられている。   The elastic member 19 has a bottomed cylindrical shape made of silicon rubber, and is attached to the operation button 18 so as to protrude downward from the lower end of the operation button 18 and come into contact with the bottom surface of the fitting recess 12c.

以上のように構成された口部材１２をベース部材１１に取り付けるには、図９（ａ）に示すように、まず、口部材１２を正面から見てその外周面に第１被係止部１２ａ及び第２被係止部１２が形成されていない左後方部分及び右前方部分が、ベース部材１１の左右の第２係止部１１ｂにそれぞれ対応するように、保持部材１７がベース部材１１の第３係止部１１ｃに対応する位置（以下、保持位置という。）から反時計回りに３０度程度回転させた所定位置で口部材１２をベース部材１１に下方側から嵌合させると、口部材１２の第１被係止部１２ａ及び第２被係止部１２ｂの双方がベース部材１１の第１係止部１１ａの下面に当接した状態となる。このとき、保持部材１７の操作ボタン１８は、第３被係止部１８ａがベース部材１１の第１係止部１１ａの下面に当接し、下方側に押し下げられた状態となっている。   In order to attach the mouth member 12 configured as described above to the base member 11, as shown in FIG. 9A, first, the mouth member 12 is viewed from the front, and the first locked portion 12a is formed on the outer peripheral surface thereof. In addition, the holding member 17 is the first member of the base member 11 so that the left rear portion and the right front portion where the second locked portion 12 is not formed correspond to the left and right second engaging portions 11b of the base member 11, respectively. When the mouth member 12 is fitted to the base member 11 from the lower side at a predetermined position rotated about 30 degrees counterclockwise from a position corresponding to the three locking portions 11c (hereinafter referred to as a holding position), the mouth member 12 is inserted. Both the first locked portion 12a and the second locked portion 12b are in contact with the lower surface of the first locking portion 11a of the base member 11. At this time, the operation button 18 of the holding member 17 is in a state where the third locked portion 18 a is in contact with the lower surface of the first locking portion 11 a of the base member 11 and is pressed downward.

続いて、口部材１２を時計回りに回転させる（以下、時計回りの回転を正回転という。）と、同図（ｂ）に示すように、口部材１２の第２被係止部１２ｂがベース部材１１の第２係止部１１ｂの上側を移動していき、正面から見て左側の第２被係止部１２ｂの後端部が後部側の第１係止部１１ａにおける左側の前端面に、正面から見て右側の第２被係止部１２ｂの前端部が前部側の第１係止部１１ａにおける右側の後端面にそれぞれ当接し、保持位置で口部材１２の回転が停止する（同図（ｃ）参照）。   Subsequently, when the mouth member 12 is rotated clockwise (hereinafter, clockwise rotation is referred to as forward rotation), the second locked portion 12b of the mouth member 12 becomes the base as shown in FIG. The upper end of the second locking portion 11b of the member 11 is moved, and the rear end portion of the second locked portion 12b on the left side when viewed from the front is brought to the left front end surface of the first locking portion 11a on the rear side. The front end portion of the second locked portion 12b on the right side when viewed from the front is in contact with the rear end surface of the right side of the first locking portion 11a on the front side, and the rotation of the mouth member 12 stops at the holding position ( (See (c) in the figure).

このようにして、口部材１２を保持位置まで回転させた状態では、図５及び図１０に示すように、ベース部材１１の第１係止部１１ａの下側に口部材１２の第１被係止部１２ａが、ベース部材１１の第２係止部１１ｂの上側に口部材１２の第２被係止部１２がそれぞれ位置しており、これによって、ベース部材１１に嵌合させた口部材１２が上下方向に位置決めされると共に、操作ボタン１８の第３被係止部１８ａがベース部材１１の第３係止部１１ｃに対応する位置に移動しており、弾性部材１９の付勢力によって押し上げられた操作ボタン１８の第３被係止部１８ａがベース部材１１の第３係止部１１ｃに嵌合することで係止され、口部材１２が回転不能な状態となるので、口部材１２がベース部材１１に取り付けられた状態に保持される。   Thus, in the state where the mouth member 12 is rotated to the holding position, as shown in FIGS. 5 and 10, the first engagement of the mouth member 12 below the first locking portion 11 a of the base member 11. The second locking portion 12 of the mouth member 12 is positioned above the second locking portion 11 b of the base member 11, and the stopper member 12 a is thus fitted to the base member 11. Is positioned in the vertical direction, and the third locked portion 18a of the operation button 18 is moved to a position corresponding to the third locking portion 11c of the base member 11, and is pushed up by the biasing force of the elastic member 19. Since the third locked portion 18a of the operation button 18 is locked by fitting into the third locking portion 11c of the base member 11, the mouth member 12 becomes non-rotatable. Is held attached to the member 11 .

逆に、口部材１２をベース部材１１から取り外す場合は、図１１に示すように、操作ボタン１８を押し下げることによって、ベース部材１１の第３係止部１１ｃに対する操作ボタン１８の第３被係止部１８ａの嵌合を解除し、口部材１２を所定位置まで逆回転させると、口部材１２の第１被係止部１２ａ及び第２被係止部１２ｂの双方がベース部材１１の第１係止部１１ａの下側に位置した状態となり、ベース部材１１に対する口部材１２の下方側への抜止め状態が解除されるので、口部材１２をベース部材１１の下方側に引き抜けばよい。   Conversely, when the mouth member 12 is removed from the base member 11, as shown in FIG. 11, the third engagement of the operation button 18 with respect to the third engagement portion 11 c of the base member 11 is performed by pushing down the operation button 18. When the fitting of the portion 18a is released and the mouth member 12 is reversely rotated to a predetermined position, both the first locked portion 12a and the second locked portion 12b of the mouth member 12 are in the first relationship of the base member 11. Since it will be in the state located in the lower side of the stop part 11a, and the state from which the lower direction of the mouth member 12 with respect to the base member 11 is released, the mouth member 12 may be pulled out to the lower side of the base member 11.

前記蓋部材２０は、図１〜図５に示すように、円形状の天板の周縁部に周壁が連設された蓋本体２１と、この蓋本体２１の天板の内面に固着された、蓋部材２０を閉じたときに口栓部材１０の口部材１２内に入り込む閉塞部２２と、この閉塞部２２に嵌着されるパッキン２３とを備えており、蓋部材２０を閉じたときに、パッキン２３が嵌着された閉塞部２２によって、口部材１２の隔壁１３に形成された注出孔１４が密閉されるようになっている。   As shown in FIGS. 1 to 5, the lid member 20 is fixed to a lid main body 21 having a peripheral wall continuously connected to a peripheral portion of a circular top plate, and an inner surface of the top plate of the lid main body 21. When the lid member 20 is closed, the closure member 22 that enters the mouth member 12 of the plug member 10 and the packing 23 that is fitted to the closure member 22 are provided. When the lid member 20 is closed, The outlet hole 14 formed in the partition wall 13 of the mouth member 12 is hermetically sealed by the closing portion 22 to which the packing 23 is fitted.

前記開閉手段３０は、図１〜図３及び図５に示すように、蓋部材２０における蓋本体２１の周壁の前面側に突出する正面視門型形状の区画壁２１ａによって下部を除く三方が囲われた蓋側開閉操作領域の下端部に形成された係止爪３１と、蓋本体２１の区画壁２１ａに対向するように、口栓部材１０におけるベース部材１１の前面側に突出する正面Ｕ字状の区画壁１１ｄによって上部を除く三方が囲われたベース側開閉操作領域内で、上下が前後方向に揺動するように区画壁１１ｄに軸支された、係止爪３１に係合可能な係合凹部３３を上部に有する開閉操作部材３２と、ベース側開閉操作領域と開閉操作部材３２との間に配設された、開閉操作部材３２における揺動軸３４よりも下側部分を外側（前方側）に付勢するコイルバネ３５とを備えており、係止爪３１は、蓋本体２１の蓋側開閉操作領域内の左半部に形成されていると共に、蓋側開閉操作領域内の右半部は前後方向に開放されている。   As shown in FIGS. 1 to 3 and 5, the opening / closing means 30 is surrounded on three sides except for the lower part by a partition wall 21 a having a frontal gate shape projecting to the front side of the peripheral wall of the lid body 21 in the lid member 20. A front U-shape projecting to the front side of the base member 11 in the plug member 10 so as to face the locking claw 31 formed at the lower end of the opened lid-side opening / closing operation area and the partition wall 21a of the lid body 21. Can be engaged with a locking claw 31 that is pivotally supported by the partition wall 11d so that the top and bottom of the base side opening / closing operation region is surrounded in three sides except for the upper part by the partition wall 11d. An opening / closing operation member 32 having an engaging recess 33 in the upper part, and a lower portion of the opening / closing operation member 32 disposed between the base-side opening / closing operation region and the opening / closing operation member 32 outside the swing shaft 34 (outside ( Coil spring 35 biasing forward) And, locking pawl 31, as well is formed in the left half of the cover-side opening and closing region of the cover body 21, the right half portion of the lid side opening and closing area is open in the front-rear direction.

前記係合凹部３３は、蓋本体２１の蓋側開閉操作領域内の左半部に形成された係止爪３１に対応するように、開閉操作部材３２の左半部に形成されており、その係合凹部３３が形成された開閉操作部材３２の上部がベース部材１１のベース側開閉操作領域の上方側に張り出している。   The engaging recess 33 is formed in the left half of the opening / closing operation member 32 so as to correspond to the locking claw 31 formed in the left half of the lid side opening / closing operation area of the lid body 21. The upper part of the opening / closing operation member 32 in which the engagement recess 33 is formed protrudes above the base side opening / closing operation region of the base member 11.

従って、開いた状態の蓋部材２０を閉じると、口栓部材１０に取り付けた開閉操作部材３２の係合凹部３３よりも上端側が、蓋部材２０に形成された係止爪３１に接触することによって、開閉操作部材３２の上端部が外側に押し広げられながら係止爪３１を乗り越えて係合凹部３３が係止爪３１に係合し、これによって蓋部材２０が全閉位置に位置決めされるようになっている（図２参照）。   Therefore, when the lid member 20 in the opened state is closed, the upper end side of the opening / closing operation member 32 attached to the plug member 10 comes into contact with the locking claw 31 formed on the lid member 20. As the upper end of the opening / closing operation member 32 is pushed outward, the engagement claw 31 gets over the engagement claw 31 and the engagement recess 33 engages with the engagement claw 31 so that the lid member 20 is positioned at the fully closed position. (See FIG. 2).

また、蓋部材２０が全閉位置に位置決めされた状態で、図１２に示すように、コイルバネ３５の付勢力に抗して開閉操作部材３２の下部を押し込むと、係止爪３１に対する係合凹部３３の係合が解除されるので、ねじりバネの付勢力によって、蓋部材２０が全開位置まで開くようになっている（図５参照）。   When the lid member 20 is positioned at the fully closed position and the lower part of the opening / closing operation member 32 is pushed against the urging force of the coil spring 35 as shown in FIG. Since the engagement of 33 is released, the lid member 20 is opened to the fully open position by the biasing force of the torsion spring (see FIG. 5).

前記ロック機構４０は、図１及び図３に示すように、蓋本体２１における蓋側開閉操作領域の右外側に形成された、区画壁２１ａと区画壁２１ｂとによって囲まれたロック操作領域内に、ロック位置とロック解除位置との間で周方向にスライド可能に支持されたロック操作部材４１と、ロック位置にスライドさせたロック操作部材４１の左端部が係合可能な、開閉操作部材３２における上部の右半部に形成された係合部４５とを備えており、蓋部材２０を全閉にした状態、即ち、開閉操作部材３２の係合凹部３３が係止爪３１に係合した状態で、ロック操作部材４１をロック位置にスライドさせると、ロック操作部材４１の左端部が蓋本体２１における蓋側開閉操作領域内の右半部に進入して、開閉操作部材３２の係合部４５に係合することで、開閉操作部材３２の押込操作を阻止するようになっている（図１３（ａ）、（ｂ）参照）。   As shown in FIGS. 1 and 3, the lock mechanism 40 is formed in a lock operation region formed on the right outer side of the lid side opening / closing operation region in the lid body 21 and surrounded by the partition wall 21 a and the partition wall 21 b. In the opening / closing operation member 32, the lock operation member 41 supported so as to be slidable in the circumferential direction between the lock position and the lock release position and the left end portion of the lock operation member 41 slid to the lock position can be engaged. And a state in which the lid member 20 is fully closed, that is, the engagement recess 33 of the opening / closing operation member 32 is engaged with the locking claw 31. Thus, when the lock operation member 41 is slid to the lock position, the left end portion of the lock operation member 41 enters the right half of the lid side opening / closing operation area in the lid main body 21, and the engagement portion 45 of the opening / closing operation member 32 is moved. Engaging , So as to prevent the pushing operation of the opening and closing operation member 32 (FIG. 13 (a), (b) refer).

以上のように、この飲料容器の栓体１は、所定位置においてベース部材１１に口部材１２を嵌合させ、口部材１２を保持位置まで正回転させるという簡単な操作で、口部材１２をベース部材１１に装着することができ、この装着状態において、操作ボタン１８の第３係止部１１ｃに対する係止を解除し、口部材１２を所定位置まで逆回転させるという簡単な操作で、口部材１２をベース部材１１から取り外すことができるので、ベース部材１１に対して口部材１２を簡単に着脱することができる。   As described above, the stopper 1 of the beverage container can be configured so that the mouth member 12 is fitted to the base member 11 at a predetermined position, and the mouth member 12 is rotated forward to the holding position. It can be attached to the member 11, and in this attached state, the mouth member 12 can be simply operated by releasing the engagement of the operation button 18 with respect to the third locking portion 11 c and rotating the mouth member 12 backward to a predetermined position. Can be removed from the base member 11, so that the mouth member 12 can be easily attached to and detached from the base member 11.

しかも、ベース部材１１に装着された口部材１２の所定位置を押し下げるだけで口部材がベース部材から簡単に外れてしまう従来の栓体とは異なり、操作ボタン１８を押し下げて操作ボタン１８の第３係止部１１ｃに対する係止を解除した後、口部材１２を所定位置まで逆回転させるという２段階動作を行わなければ、ベース部材１１から口部材１２を取り外すことができないので、意図していないにも拘わらず、誤操作により口部材１２が外れてしまうというおそれもない。   Moreover, unlike the conventional plug body in which the mouth member is easily detached from the base member simply by depressing a predetermined position of the mouth member 12 attached to the base member 11, the operation button 18 is pushed down and the third of the operation button 18 is removed. Since the mouth member 12 cannot be removed from the base member 11 unless the two-step operation of reversely rotating the mouth member 12 to a predetermined position is performed after releasing the latching with respect to the latching portion 11c, it is not intended. Nevertheless, there is no fear that the mouth member 12 will come off due to an erroneous operation.

特に、この飲料容器の栓体１は、操作ボタン１８を押し下げることで、第３係止部１１ｃに対する操作ボタン１８の係止が解除されるようになっているので、第３係止部１１ｃに対する操作ボタン１８の係止解除操作に煩わしさを感じることもない。   In particular, the stopper 1 of the beverage container is configured such that when the operation button 18 is pushed down, the lock of the operation button 18 with respect to the third lock portion 11c is released. There is no inconvenience in the unlocking operation of the operation button 18.

本考案は、携帯用魔法瓶や水筒等の携帯用飲料容器等の飲料容器の栓体として利用することができる。   The present invention can be used as a plug for a beverage container such as a portable beverage container such as a portable thermos bottle or water bottle.
