Description

本発明はポット等の液体容器の中栓構造、特にその操作スイッチロック構造に関する。   The present invention relates to an inner stopper structure of a liquid container such as a pot, and more particularly to an operation switch lock structure thereof.

従来、中栓の弁体を開閉する機構には、特許文献１，特許文献２に記載のように、弁体の弁軸上端を半球状に形成し、該半球状の弁軸上端を操作スイッチの傾斜面に当接させ、操作スイッチを水平に移動させることにより、弁軸を上下に移動させて、弁体を開閉するものが知られている。   Conventionally, the mechanism for opening and closing the valve body of the inner plug has a semispherical upper end of the valve shaft of the valve body as described in Patent Document 1 and Patent Document 2, and the upper end of the hemispherical valve shaft is an operation switch. It is known to open and close the valve body by moving the valve shaft up and down by moving the operation switch horizontally by contacting the inclined surface of the valve.

この種の弁体開閉機構では、操作スイッチを弁体の開き方向に操作したときにクリック感を得るとともにその位置にロックする構造が、特許文献１に記載されている。すなわち、操作スイッチを弁体の開き方向に操作したときに、弁軸の先端が操作スイッチの傾斜面を移動し、凸部を乗り越えて傾斜面の頂部に設けた凹部に係合するようになっている。   In this type of valve body opening / closing mechanism, Patent Document 1 discloses a structure in which a click feeling is obtained and the position is locked when the operation switch is operated in the opening direction of the valve body. That is, when the operation switch is operated in the opening direction of the valve body, the tip of the valve shaft moves on the inclined surface of the operation switch, gets over the convex portion, and engages with the concave portion provided on the top of the inclined surface. ing.

しかしながら、前記従来のロック構造では、操作スイッチを開閉操作する毎に、常時ばねで上方に付勢された弁軸により凸部が摩耗され、開き方向に操作した操作スイッチが不意に解除され、閉じ方向に戻ってしまうという問題があった。
特開平１０−３２８０４０号公報 特開平９−２９９２５３号公報 However, in the conventional lock structure, whenever the operation switch is opened and closed, the convex portion is worn by the valve shaft constantly biased upward by the spring, and the operation switch operated in the opening direction is unexpectedly released and closed. There was a problem of returning to the direction.
JP-A-10-328040 Japanese Patent Laid-Open No. 9-299253

本発明は、前記従来の問題点に鑑みてなされたもので、操作スイッチのロックが不意に解除されて閉じ方向に戻ってしまうことがなく、確実に操作スイッチのロックを維持することができ、耐久性がよく安全な液体容器の中栓構造を提供することを課題とする。   The present invention has been made in view of the above-described conventional problems, the operation switch is not unlocked unexpectedly and does not return to the closing direction, can reliably maintain the lock of the operation switch, It is an object to provide an inner stopper structure of a liquid container that is durable and safe.

前記課題を解決するために、本発明は、
容器本体の開口部に着脱可能に装着される中栓本体の内側に、前記容器本体の内部に開口する入口から外部に開口する出口に至る流水経路を形成し、前記流水経路の入口を閉じる方向に付勢された弁体を設け、前記中栓本体の上端に該中栓本体の上端開口部を閉じるカバーを設け、前記カバーに前記弁を開閉する操作スイッチをスライド可能に設け、前記弁体の弁軸をばねで上方に付勢して前記弁軸の上端を前記操作スイッチのカム板に当接させた液体容器の中栓構造において、
前記カバーと前記操作スイッチのいずれか一方に弾性片と係合部、他方に前記弁体を開く方向に前記操作スイッチを操作したときに前記係合部に係合する被係合部を設け、
前記弾性片は、前記カバーに設けた開口部の前側縁に後側に向かって形成し、
前記係合部は、前記弾性片の先端部上面に形成し、
前記被係合部は、前記操作スイッチの裏面に下方に垂下し、前記カム板の両側に形成したガイド板の下端に形成した凹部としたものである。 In order to solve the above problems, the present invention provides:
A direction in which a flowing water path from an inlet opening inside the container body to an outlet opening outside is formed inside the inner plug body that is detachably attached to the opening of the container body, and the inlet of the flowing water path is closed. A valve body biased to the upper end of the inner plug body, a cover for closing the upper end opening of the inner plug body, and an operation switch for opening and closing the valve is slidably provided on the cover. In the inside plug structure of the liquid container in which the valve shaft is urged upward by a spring and the upper end of the valve shaft is brought into contact with the cam plate of the operation switch,
Either one of the cover and the operation switch is provided with an elastic piece and an engagement portion, and the other is provided with an engaged portion that engages with the engagement portion when the operation switch is operated in a direction to open the valve body,
The elastic piece is formed toward the rear side at the front edge of the opening provided in the cover,
The engaging portion is formed on the top surface of the tip of the elastic piece,
The engaged portion hangs downward on the back surface of the operation switch and is a recess formed at the lower end of a guide plate formed on both sides of the cam plate .

前記構成において、弁体を開く方向に操作スイッチを操作すると、カバーと操作スイッチの係合部と被係合部が係合して、ロックされる。   In the said structure, if an operation switch is operated in the direction which opens a valve body, the engaging part and engaged part of a cover and an operation switch will engage, and will be locked.

なお、前側とは、弁体を開く方向に操作スイッチを操作する側をいい、後側とはその反対側をいう。前後方向も同様である。 In addition, the front side means the side which operates an operation switch in the direction which opens a valve body, and a rear side means the opposite side. The same applies to the front-rear direction.

前記突片は、前記カム板の両側に形成したガイド片としたので、簡単にロック構造を設けることができる。 The protrusion is, since the guide pieces formed on both sides of the cam plate can be provided with a simple locking structure.

前記操作スイッチは前記カバーの段部に下方から係合する爪を有し、前記ばねで上方に付勢された前記弁体により前記操作スイッチが上方に付勢されて、前記操作スイッチの爪が前記カバーの段部に密接するようにすることが好ましい。   The operation switch has a claw that engages with the step of the cover from below, and the operation switch is urged upward by the valve body that is urged upward by the spring. It is preferable to be in close contact with the step of the cover.

本発明によれば、カバーと操作スイッチのいずれか一方に弾性片と係合部、他方に弁体を開く方向に操作スイッチを操作したときに係合部に係合する被係合部を設け、弁体を開く方向に操作スイッチを操作すると、カバーと操作スイッチの係合部と被係合部が係合して、ロックされる。
ばねで付勢された弁軸がカム板に当接する力は、弁体が流水経路の入口を閉じるのに十分な力が必要であるが、係合部と被係合部が係合するときの弾性片の曲げ力は、ロックを維持するだけの力でよく、弁軸がカム板に当接する力よりも小さくて済む。
したがって、操作スイッチのロック時に、ロックが不意に解除されて閉じ方向に戻ってしまうことがなく、確実に操作スイッチのロックを維持することができ、耐久性がよく安全である。 According to the present invention, the elastic piece and the engaging portion are provided on one of the cover and the operation switch, and the engaged portion that is engaged with the engaging portion when the operation switch is operated in the direction of opening the valve body is provided on the other. When the operation switch is operated in the direction to open the valve body, the engaging portion of the cover and the operation switch and the engaged portion are engaged and locked.
The force with which the valve shaft biased by the spring abuts against the cam plate needs to be sufficient for the valve body to close the inlet of the flowing water path, but when the engaging part and the engaged part are engaged. The bending force of the elastic piece is sufficient to maintain the lock, and may be smaller than the force with which the valve shaft abuts the cam plate.
Therefore, when the operation switch is locked, the lock is not released unexpectedly and does not return to the closing direction, so that the operation switch can be reliably locked, and durability is high and safe.

また、ばねで上方に付勢された弁体により操作スイッチが上方に付勢されて、操作スイッチの爪がカバーの段部に密接するようにしたので、カバーと操作スイッチの位置関係が正確に規定され、カバーの弾性片の係合爪と、操作スイッチの被係合凹部との位置関係も正確に定まり、常に安定した操作力が得られるという効果を奏する。   In addition, since the operation switch is urged upward by the valve body biased upward by the spring so that the claw of the operation switch is in close contact with the stepped portion of the cover, the positional relationship between the cover and the operation switch is accurate. The positional relationship between the engagement claw of the elastic piece of the cover and the engaged recess of the operation switch is accurately determined, and there is an effect that a stable operation force can always be obtained.

次に、以上の構成からなる中栓の組み付け手順及び動作を説明する。   Next, the assembly procedure and operation of the inner plug having the above configuration will be described.

まず、図２に示すように、中栓本体１１に弁体１２を組み付け、ばね３６により上方に付勢しておく。一方、カバー１３の開口部４２に操作スイッチ１４の弾性片４９を挿入して、弾性片４９の爪５０をカバー１３の段部４６に係合させる。これにより、操作スイッチ１４は、前側のストッパ５６がカバー１３の開口部４２の前側縁に当接する位置と、後側のストッパ５７がカバー１３の開口部４２の後側縁に当接する位置との間で、カバー１３のガイド壁４１に沿ってスライド可能に組み付けられる。   First, as shown in FIG. 2, the valve body 12 is assembled to the inner plug main body 11 and biased upward by the spring 36. On the other hand, the elastic piece 49 of the operation switch 14 is inserted into the opening 42 of the cover 13, and the claw 50 of the elastic piece 49 is engaged with the step 46 of the cover 13. As a result, the operation switch 14 has a position in which the front stopper 56 contacts the front edge of the opening 42 of the cover 13 and a position in which the rear stopper 57 contacts the rear edge of the opening 42 of the cover 13. In the meantime, it is slidably assembled along the guide wall 41 of the cover 13.

次に、カバー１３の前側の第１被係合突起３８を中栓本体１１の上端の第１係合穴２８に係合し、カバー１３の後側を中栓本体１１の上端に向かって押し付ける。すると、中栓本体１１の弾性片３０の上端の第２係合爪３１がカバー１３の鍔部３７を乗り越えて第２係合凹部４０に係合し、カバー１３が中栓本体１１に組み付けられる。このとき、カバー１３の鍔部３７の内面が中栓本体１１のフランジ部２７に密着して、中栓本体１１は密閉される。また、カバー１３が中栓本体１１に組み付けられると同時に、図６（ａ）に示すように、中栓本体１１の弁軸３３の上端が操作スイッチ１４のカム板５２のカム面５１に当接し、操作スイッチ１４は後方に移動させられ、後側のストッパ５７がカバー１３の開口部４２の後側縁に当接して停止した状態となる。この状態では、図６（ａ）に示すように、弁体１２はばね３６により上方に付勢され、弁軸３３の上端は操作スイッチ１４のカム板５２の最上端に位置している。   Next, the first engagement protrusion 38 on the front side of the cover 13 is engaged with the first engagement hole 28 at the upper end of the inner plug body 11, and the rear side of the cover 13 is pressed toward the upper end of the inner plug body 11. . Then, the second engagement claw 31 at the upper end of the elastic piece 30 of the inner plug body 11 gets over the flange 37 of the cover 13 and engages with the second engagement recess 40, and the cover 13 is assembled to the inner plug body 11. . At this time, the inner surface of the collar portion 37 of the cover 13 is in close contact with the flange portion 27 of the inner plug body 11, and the inner plug body 11 is sealed. Further, at the same time that the cover 13 is assembled to the inner plug main body 11, the upper end of the valve shaft 33 of the inner plug main body 11 comes into contact with the cam surface 51 of the cam plate 52 of the operation switch 14 as shown in FIG. The operation switch 14 is moved rearward, and the rear stopper 57 comes into contact with the rear edge of the opening 42 of the cover 13 and stops. In this state, as shown in FIG. 6A, the valve body 12 is biased upward by the spring 36, and the upper end of the valve shaft 33 is positioned at the uppermost end of the cam plate 52 of the operation switch 14.

このように組み付けた中栓１０は、図１に示すように、外周の雄ねじ部２６を容器本体２の肩体７の雌ねじ部２５に螺合して、容器本体２の開口部に取り付ける。このとき、図示しないストッパにより、中栓１０は流水経路１８の出口１７が肩体７の注口６に一致した状態で停止する。また、中栓本体１１のパッキン２３は、容器本体２の内容器２ａの段部２ｃに当接し、シールリング２４は容器本体２の肩体７の内面に当接して、容器本体２内の液体の漏出が防止される。   As shown in FIG. 1, the inner plug 10 assembled in this way is attached to the opening of the container main body 2 by screwing the male screw portion 26 on the outer periphery with the female screw portion 25 of the shoulder body 7 of the container main body 2. At this time, the stopper 10 (not shown) stops the inner plug 10 in a state in which the outlet 17 of the water flow path 18 coincides with the spout 6 of the shoulder body 7. Further, the packing 23 of the inner cap body 11 abuts on the step 2c of the inner container 2a of the container body 2, and the seal ring 24 abuts on the inner surface of the shoulder body 7 of the container body 2, so that the liquid in the container body 2 is retained. Leakage is prevented.

容器本体２に収容した液体を注ぎ出すには、容器本体２のハンドル８を持って親指等で操作スイッチ１４を前方に押し出す。これにより、図６（ｂ）に示すように、操作スイッチ１４が前方に移動し、カム板５２のカム面５１の傾斜部５１ｂが弁体１２の弁軸３３を押し下げ、弁軸３３の上端がカム板５２のカム面５１の平坦部５１ａに圧接し、前側のストッパ５６がカバー１３の開口部４２の前側縁に当接して停止する。これと同時に、図７に示すように、カバー１３の弾性片４３の先端の係合爪４４が操作スイッチ１４のガイド板５３の山部５５を乗り越え、被係合凹部５４に係合して、ロックされる。   In order to pour out the liquid stored in the container body 2, the operation switch 14 is pushed forward with the thumb or the like while holding the handle 8 of the container body 2. 6B, the operation switch 14 moves forward, the inclined portion 51b of the cam surface 51 of the cam plate 52 pushes down the valve shaft 33 of the valve body 12, and the upper end of the valve shaft 33 is The front stopper 56 comes into pressure contact with the flat portion 51 a of the cam surface 51 of the cam plate 52, and stops in contact with the front edge of the opening 42 of the cover 13. At the same time, as shown in FIG. 7, the engaging claw 44 at the tip of the elastic piece 43 of the cover 13 gets over the crest portion 55 of the guide plate 53 of the operation switch 14 and engages with the engaged recess 54. Locked.

ばね３６で付勢された弁軸３３がカム板５２の紙面５１に当接する力は、弁体１２が流水経路１８の入口を閉じるのに十分な力が必要である。これに対し、係合爪４４と被係合凹部５４が係合するときの弾性片３０の曲げ力は、ロックを維持するだけの力でよく、弁軸３３がカム板５２のカム面５１に当接する力よりも小さくて済む。したがって、操作スイッチ１４のロック時に、ロックが不意に解除されて閉じ方向に戻ってしまうことがなく、確実に操作スイッチ１４のロックを維持することができ、耐久性がよく安全である。   The force with which the valve shaft 33 biased by the spring 36 abuts against the paper surface 51 of the cam plate 52 needs to be sufficient for the valve body 12 to close the inlet of the flowing water path 18. On the other hand, the bending force of the elastic piece 30 when the engaging claw 44 and the engaged recessed portion 54 engage with each other is sufficient to maintain the lock, and the valve shaft 33 is applied to the cam surface 51 of the cam plate 52. Smaller than the abutting force. Therefore, when the operation switch 14 is locked, the lock is not released unexpectedly and does not return to the closing direction, so that the operation switch 14 can be reliably locked, and the durability and safety are high.

カバー１３の弾性片４３の係合爪４４と、操作スイッチ１４の被係合凹部５４との係合の精度は非常に高くなっている。これは、バネ３６で上方に付勢された弁体１２の弁軸３３により操作スイッチ１４が上方に付勢され、操作スイッチ１４の弾性片４９の爪５０がカバー１３の段部４６に密接して、カバー１３と操作スイッチ１４の位置関係が正確に規定されているため、カバー１３の弾性片４３の係合爪４４と、操作スイッチ１４の被係合凹部５４との位置関係も正確に定まっているからである。これにより、常に安定したスイッチ操作を行うことができる。   The accuracy of engagement between the engaging claw 44 of the elastic piece 43 of the cover 13 and the engaged recess 54 of the operation switch 14 is very high. This is because the operation switch 14 is urged upward by the valve shaft 33 of the valve body 12 urged upward by the spring 36, and the claw 50 of the elastic piece 49 of the operation switch 14 is in close contact with the step 46 of the cover 13. Since the positional relationship between the cover 13 and the operation switch 14 is accurately defined, the positional relationship between the engagement claw 44 of the elastic piece 43 of the cover 13 and the engaged recess 54 of the operation switch 14 is also accurately determined. Because. Thereby, it is possible to always perform stable switch operation.

弁軸３３が押し下げられると、弁３２が流水経路１８の入口１６から離脱するので、流水経路１８の入口１６が開口し、該入口１６から流水経路１８に容器本体２内の液体が流入し、出口１７を経て注口６からコップ等に注がれる。   When the valve shaft 33 is pushed down, the valve 32 is detached from the inlet 16 of the flowing water path 18, so that the inlet 16 of the flowing water path 18 is opened, and the liquid in the container body 2 flows into the flowing water path 18 from the inlet 16. It is poured into a cup or the like from the spout 6 via the outlet 17.

操作スイッチ１４を前方に押し出す際にカバー１３に作用する押圧力は、図６中矢印で示すように水平であって、中栓本体１１の弾性片３０の第２係合爪３１とカバー１３の第２被係合凹部４０との係合を解除する方向、すなわち、垂直方向には作用しない。よって、液体を注ぐために操作スイッチ１４を操作したときに、意図せずに、カバー１３が中栓本体１１から外れてしまうことがない。さらに、操作スイッチ１４の前後のスライド方向と、中栓本体１１の弾性片３０の第２係合爪３１とカバー１３の第２被係合凹部４０の係合方向、中栓本体１１の第１係合穴とカバー１３の第１被係合突起３８の係合方向が平行であるため、操作スイッチ１４の操作時に中栓本体１１が分解してしまうのをより一層防止することができる。   The pressing force acting on the cover 13 when the operation switch 14 is pushed forward is horizontal as indicated by an arrow in FIG. 6, and the second engaging claw 31 of the elastic piece 30 of the inner plug body 11 and the cover 13 It does not act in the direction of releasing the engagement with the second engaged recess 40, that is, in the vertical direction. Therefore, when the operation switch 14 is operated to pour liquid, the cover 13 is not unintentionally detached from the inner plug body 11. Furthermore, the sliding direction before and after the operation switch 14, the engaging direction of the second engaging claw 31 of the elastic piece 30 of the inner plug body 11 and the second engaged recess 40 of the cover 13, the first of the inner plug body 11. Since the engagement direction of the engagement hole and the first engagement protrusion 38 of the cover 13 are parallel, it is possible to further prevent the inner plug body 11 from being disassembled when the operation switch 14 is operated.

容器本体２内の液体を注ぎ出している間は、容器本体２の内部は、中栓１０の流水経路１８の入口１６、通気経路２１、排水口２２、中栓本体１１の仕切壁１５より上の空間、カバー１３の開口部４２、カバー１３と操作スイッチ１４の間の隙間を介して外気と連通しており、外気が容器本体２内に流入するので、内部の液体をスムーズに注出することができる。   While the liquid in the container body 2 is being poured out, the inside of the container body 2 is above the inlet 16 of the flowing water path 18 of the inner plug 10, the ventilation path 21, the drain port 22, and the partition wall 15 of the inner plug body 11. Space, the opening 42 of the cover 13, and the gap between the cover 13 and the operation switch 14 communicate with the outside air, and the outside air flows into the container body 2, so that the liquid inside is smoothly poured out. be able to.

操作スイッチ１４を後方に引き込むと、カバー１３の弾性片４３の先端の係合爪４４と操作スイッチ１４の被係合凹部５４との係合によるロックが解除され、弁体１２の弁軸３３がそのばね３６の付勢によりカム板５２のカム面５１の傾斜面５１ａを押圧して、図６（ａ）に示すように、操作スイッチ１４が後方に移動し、弁軸３３の上端がカム板５２の最上端に位置し、後側のストッパ５７がカバー１３の開口部４２の後側縁に当接して停止する。   When the operation switch 14 is pulled backward, the lock caused by the engagement between the engagement claw 44 at the tip of the elastic piece 43 of the cover 13 and the engaged recess 54 of the operation switch 14 is released, and the valve shaft 33 of the valve body 12 is released. The inclined surface 51a of the cam surface 51 of the cam plate 52 is pressed by the bias of the spring 36, so that the operation switch 14 moves rearward as shown in FIG. 6A, and the upper end of the valve shaft 33 is connected to the cam plate. Positioned at the uppermost end of 52, the rear stopper 57 comes into contact with the rear edge of the opening 42 of the cover 13 and stops.

中栓本体１１の仕切壁１５より上方の空間内で結露した水は、排水口２２より排出される。また、中栓本体１１内を洗浄するためにカバー１３を取り外すには、中栓本体１１の弾性片３０を押圧し、弾性片３０の第２係合爪３１とカバー１３の第２被係合凹部４０の係合を解除して、カバー１３の突部３９を上方に押す。これにより、カバー１３が中栓本体１１から取り外され、中栓本体１１の仕切壁１５より上方の空間、カバー１３及び操作スイッチ１４の内面を洗浄することができる。弾性片３０を押圧したとき、弾性片３０の必要以上の変形は、カバー１３に設けた規制板４７によって規制されるので、弾性片３０が塑性変形して第２係合爪３０と第２被係合凹部４０の係合が不十分になることがない。   Water condensed in the space above the partition wall 15 of the inner plug body 11 is discharged from the drain port 22. Further, in order to remove the cover 13 in order to clean the inside of the inner plug main body 11, the elastic piece 30 of the inner plug main body 11 is pressed, and the second engagement claw 31 of the elastic piece 30 and the second engaged portion of the cover 13 are engaged. The engagement of the recess 40 is released, and the protrusion 39 of the cover 13 is pushed upward. Thereby, the cover 13 is removed from the inner plug main body 11, and the space above the partition wall 15 of the inner plug main body 11, the cover 13, and the inner surface of the operation switch 14 can be cleaned. When the elastic piece 30 is pressed, excessive deformation of the elastic piece 30 is restricted by the restriction plate 47 provided on the cover 13, so that the elastic piece 30 is plastically deformed and the second engagement claw 30 and the second covered claw 30 are deformed. The engagement of the engagement recess 40 does not become insufficient.
