Description

この発明は、密閉容器に関する。 The present invention relates to a sealed container.

一般に、密閉容器は、容器本体と、この容器本体の口部を密封する蓋とを備えている。蓋は、容器本体への収容を容易にするため、着脱可能となっている。その着脱構造として、ねじが採用されている。蓋を付けたまま、容器本体内から内容物をカップ等に注ぐことができるようにするため、内容物を注ぐための流路が、蓋の中に通されている。この流路を閉じて密閉容器内の密閉性を高めるため、蓋に弁と、弁を開くための操作機構とが設けられている（例えば、特許文献１）。 In general, a sealed container includes a container body and a lid that seals the mouth of the container body. The lid is detachable in order to facilitate accommodation in the container body. A screw is employed as the attachment / detachment structure. In order to allow the contents to be poured into the cup or the like from the container body with the lid attached, a flow path for pouring the contents is passed through the lid. In order to close this flow path and improve the airtightness in the airtight container, a valve and an operation mechanism for opening the valve are provided on the lid (for example, Patent Document 1).

実開昭５８−１７９０７１号公報Japanese Utility Model Publication No. 58-179071

ねじ式の蓋を採用すると、ねじ部の清掃性が良くない。また、何度も蓋を回して外す必要があるため、面倒であった。この問題は、蓋を直線的な動きで着脱可能な構造にすれば回避できる。 If a screw-type lid is used, the cleaning of the threaded portion is not good. In addition, it is troublesome because it is necessary to turn the lid many times to remove it. This problem can be avoided by making the lid detachable with a linear motion.

しかしながら、例えばポットのように、容器本体に熱い内容物を蓄える場合、大気と遮断されている容器本体の内圧が上昇する。蓋を直線的な動きで着脱可能な構造にする場合、蓋が内圧で押されても外れることがないようにすることが必要になる。 However, when hot contents are stored in the container body, such as a pot, the internal pressure of the container body that is blocked from the atmosphere increases. When the lid is structured to be detachable by a linear movement, it is necessary to prevent the lid from coming off even if the lid is pushed by internal pressure.

そこで、この発明が解決しようとする課題は、密閉容器の容器本体に対して蓋を直線的な動きで着脱可能でありながら、蓋が容器本体の内圧で押されても外れないようにすることである。 Therefore, the problem to be solved by the present invention is to prevent the lid from being removed even if the lid is pushed by the internal pressure of the container body, while the lid can be attached to and detached from the container body of the sealed container by a linear movement. It is.

上記の課題を解決するため、本願発明者は、容器本体と、この容器本体の口部を密封する蓋とを備えている密閉容器において、前記蓋に組み込んだフックが前記容器本体のフック受部から外れるロック解除動作によって、前記蓋を直線移動で前記容器本体から引き抜くことが可能になる構造の採用を検討した。この蓋の着脱・ロック構造によれば、容器本体に対して蓋を直線的な動きで着脱可能でありながら、蓋が容器本体の内圧で押されても、ロック解除操作をしない限り蓋が容器本体から外れないようにすることができる。 In order to solve the above problems, the inventor of the present application, in a sealed container having a container main body and a lid for sealing the mouth of the container main body, has a hook incorporated in the lid, the hook receiving portion of the container main body. The adoption of a structure that enables the lid to be pulled out from the container body by linear movement by the unlocking operation that is released from the container was studied. According to this lid attaching / detaching / locking structure, the lid can be attached to and detached from the container main body by a linear movement, but even if the lid is pressed by the internal pressure of the container main body, the lid remains in the container unless the unlocking operation is performed. It can be prevented from coming off from the main body.

ところが、試作を行うと、容器本体に熱い内容物を蓄えて時間が経過した後、蓋を外す際、フックがフック受部から抜けた直後、大気圧を上回る容器本体の内圧で蓋が急に押し出されたり、さらに、容器本体の内壁面に付着している内容物が減圧の吹き出し流に運ばれて飛び出したりする可能性が見い出された。内圧が高いということは、飛び出す内容物も熱いということであり、これを防止しないと、安全上、前述の構造を採用することは好ましくない。なお、従来のねじ式の場合を検討すると、蓋を回して螺合を解除するのに時間を要し、この間にねじ山と谷底の隙間から減圧が進行した後に蓋が外れるため、前述の可能性を見い出せなかった。なお、ポットのように熱い飲食物を内容物とする場合、その温度は、６５℃〜１００℃である。一般的な密閉性能からすると、６時間を越えると、内容物の温度が下がるので、内圧が問題になることはなく、この条件下で安全性を確保すれば、実用的である。 However, when a prototype is made, after the time has passed since hot contents were stored in the container body, when the lid is removed, immediately after the hook is pulled out of the hook receiving portion, the lid suddenly rises due to the internal pressure of the container body exceeding atmospheric pressure. It has been found that there is a possibility that the content that has been pushed out and further adhered to the inner wall surface of the container body will be carried out by being blown out under reduced pressure. The high internal pressure means that the content that pops out is also hot. Unless this is prevented, it is not preferable to adopt the above-described structure for safety. In addition, considering the case of the conventional screw type, it takes time to release the screwing by turning the lid, and during this time, the lid comes off after the decompression proceeds from the gap between the screw thread and the valley bottom. I couldn't find sex. In addition, when using hot food and drink as a pot, the temperature is 65 to 100 degreeC. In terms of general sealing performance, the temperature of the contents drops after 6 hours, so that the internal pressure does not become a problem. If safety is ensured under these conditions, it is practical.

そこで、この発明は、前記蓋の着脱・ロック構造と共に、前記フックが前記フック受部に引っ掛かる状態で前記容器本体の内圧が大気圧を超えて上昇すると、当該フックが当該内圧に抵抗することによって姿勢変化を起こし、前記容器本体の内圧が大気圧の状態では、前記フックが、ロック解除動作しても前記蓋の静止段状部に引っ掛からない姿勢に保たれ、前記容器本体の内圧が大気圧を一定以上超えている状態では、前記フックが、ロック解除動作しても前記フック受部から外れる以前に前記静止段状部に引っ掛かる姿勢に保たれる構成の採用により、容器本体の内圧が大気圧を一定以上越えた危険な状態では、その内圧を利用した静止段状部とフックの引っ掛かりを可能とし、これにより、蓋の急な押し出しや内容物の飛び出しを防ぐことができるようにした。 Therefore, the present invention, together with the attachment / detachment / locking structure of the lid, causes the hook to resist the internal pressure when the internal pressure of the container body rises above the atmospheric pressure while the hook is hooked on the hook receiving portion. When the posture changes and the internal pressure of the container main body is atmospheric pressure, the hook is kept in a posture not to be caught by the stationary stepped portion of the lid even when the unlocking operation is performed, and the internal pressure of the container main body is atmospheric pressure. When the hook exceeds a certain level, the internal pressure of the container main body is increased by adopting a configuration in which the hook is held in a posture of being hooked on the stationary stepped portion before being detached from the hook receiving portion even when the lock is released. In a dangerous state where the atmospheric pressure exceeds a certain level, it is possible to catch the stationary stepped part and hook using the internal pressure, thereby preventing sudden extrusion of the lid and popping of the contents. Theft was to be able to.

具体的には、前記フックが、前記フック受部に引っ掛かるフック部と、前記ロック解除動作のために与えられた操作力を前記フック部に伝える操作伝達部とを有し、前記フック部が、前記静止段状部に引っ掛かる係合端を有し、前記操作伝達部と前記フック部が、前記フック受部に対する当該操作伝達部の傾きを許す揺動軸と軸受部とで連結されているとよい。この場合、内圧に抵抗するフックのうち、フック受部に引っ掛かるフック部の姿勢変化を避け、操作伝達部の傾きを利用して係合端と静止段状部の引っ掛かりを実現し、そのフック部のロック解除動作を静止段状部で直接に阻止することができる。 Specifically, the hook includes a hook part that is hooked on the hook receiving part, and an operation transmission part that transmits an operation force applied for the unlocking operation to the hook part, and the hook part includes: An engagement end that is hooked on the stationary stepped portion, and the operation transmission portion and the hook portion are connected by a swing shaft and a bearing portion that allow the operation transmission portion to tilt with respect to the hook receiving portion. Good. In this case, of the hooks that resist internal pressure, avoid the change in the posture of the hook part that is hooked to the hook receiving part, and use the inclination of the operation transmission part to realize the catch between the engaging end and the stationary stepped part. The unlocking operation can be directly prevented by the stationary step portion.

より好ましくは、前記揺動軸と前記軸受部は、前記操作伝達部と前記フック部の相対的なスライドを許し、前記操作伝達部は、前記フック部と挟持する付勢ばねを有し、前記フックがロック解除動作するとき、前記容器本体の内圧が大気圧の状態では、前記操作伝達部と前記フック部が前記付勢ばねの抵抗で連動し、前記容器本体の内圧が大気圧を一定以上超えている状態では、前記操作伝達部が前記フック部に対してスライドすることによって前記付勢ばねが蓄勢し、前記操作伝達部に操作力が与えられなくなると、当該蓄勢力によって当該操作伝達部がスライド前の位置に復帰するとよい。この場合、容器本体の内圧が大気圧を一定以上超えているためにフック部の係合端が静止段状部に引っ掛かったとき、操作伝達部だけがスライドするため、引っ掛かったままの強引なロック解除操作をスライドストロークで防ぎ、フックの傷みを防止することができる。また、使用者がロック解除操作を止めると、操作伝達部に操作力が与えられなくなるので、操作伝達部が付勢ばねの反発で自然とスライド前の位置に戻るため、次回のロック解除操作に支障はない。 More preferably, the swing shaft and the bearing portion allow relative sliding of the operation transmission portion and the hook portion, and the operation transmission portion includes a biasing spring that is clamped with the hook portion, When the hook is unlocked, if the internal pressure of the container body is atmospheric pressure, the operation transmitting portion and the hook portion are interlocked by the resistance of the biasing spring, and the internal pressure of the container body exceeds the atmospheric pressure above a certain level. In the state exceeding, when the operation transmitting portion slides with respect to the hook portion, the urging spring accumulates energy, and when the operation force is not applied to the operation transmitting portion, the operation force is caused by the accumulated force. The transmission unit may return to the position before the slide. In this case, when the engagement end of the hook part is caught by the stationary stepped part because the internal pressure of the container body exceeds the atmospheric pressure more than a certain level, only the operation transmission part slides, so that the forceful lock remains hooked. The release operation can be prevented by the slide stroke, and the hook can be prevented from being damaged. In addition, when the user stops the unlocking operation, no operating force is applied to the operation transmitting part, so the operation transmitting part naturally returns to the position before the slide due to the repulsion of the biasing spring, so the next unlocking operation There is no hindrance.

さらに好ましくは、前記蓋が、前記容器本体内と大気間に亘る連通路を開閉する弁と、前記静止段状部に引っ掛かっている前記フック部に対してスライドする前記操作伝達部の運動を前記弁の開弁動作に変換する連動機構とを有し、前記弁が開いた前記連通路から前記容器本体の内圧を逃し、前記操作伝達部に操作力を与え続けると大気圧まで減圧することができるようにするとよい。この場合、操作伝達部のスライドを利用して弁を開き、容器本体内を大気圧まで減圧することができる。これにより、フックの姿勢変化が戻って前記係合端が静止段状部に引っ掛からない状態となるので、使用者が一旦ロック解除操作を止めると、操作伝達部が前記付勢ばねで復帰させられる。この後、使用者が再びロック解除操作を行えば、今度は係合端が静止段状部に引っ掛からないので、フック部がフック受部から外れ、蓋を引き抜くことが可能になる。 More preferably, the lid moves the movement of the valve that opens and closes the communication path between the inside of the container body and the atmosphere, and the operation transmission unit that slides with respect to the hook unit hooked on the stationary stepped unit. An interlocking mechanism for converting the valve to an opening operation of the valve, allowing the internal pressure of the container body to escape from the communication path where the valve is opened, and reducing the pressure to atmospheric pressure by continuously applying the operation force to the operation transmission unit. You should be able to do it. In this case, the valve can be opened using the slide of the operation transmission unit, and the inside of the container body can be decompressed to atmospheric pressure. Thereby, the posture change of the hook is returned and the engagement end is not caught by the stationary stepped portion, so that once the user stops the unlocking operation, the operation transmitting portion is returned by the biasing spring. . Thereafter, when the user performs the unlocking operation again, the engaging end is not caught by the stationary stepped portion, so that the hook portion is detached from the hook receiving portion and the lid can be pulled out.

前述のように、操作伝達部の傾きを利用して係合端と静止段状部の引っ掛かりを実現する場合、フックを除いた蓋部分の上昇を利用することができる。 As described above, when the engagement end and the stationary stepped portion are hooked using the inclination of the operation transmitting portion, the rise of the lid portion excluding the hook can be used.

例えば、前記フック部が前記フック受部に引っ掛かる状態で前記容器本体の内圧上昇が大気圧を超えて進行すると、前記フック部を除いた蓋部分が上昇することによって前記操作伝達部が傾き、前記静止段状部が前記係合端に接近するようにしてもよい。この例は、蓋部分の上昇を利用して静止段状部をフック部の係合端に接近させるので、フック部の傾きを避け、フック受部への引っ掛かりを安定させたいときに好適である。 For example, when the increase in the internal pressure of the container main body exceeds the atmospheric pressure in a state where the hook portion is hooked on the hook receiving portion, the operation transmission portion is tilted by raising the lid portion excluding the hook portion, You may make it a stationary step-shaped part approach the said engagement end. In this example, the stationary stepped portion is brought close to the engaging end of the hook portion by using the rise of the lid portion, so that it is suitable when it is desired to avoid the inclination of the hook portion and stabilize the catch on the hook receiving portion. .

また、前記フック部が前記フック受部に引っ掛かる状態で前記容器本体の内圧上昇が大気圧を超えて進行すると、前記フック部を除いた蓋部分の上端面と当該フック部が接触することによって前記内圧に押される当該蓋部分の上昇が阻止され、当該フック部がロック解除動作する方向にずれることによって前記静止段状部が前記係合端に対向し、当該蓋部分が上昇するようにしてもよい。この例は、容器本体の内圧上昇によって蓋が容器本体から浮き上がることを蓋部分の上端面とフック部の接触で阻止することができる。このため、内圧上昇が生じても密閉容器の見栄えが悪化しない。内圧が大気圧を一定以上超えているとき、当該阻止状態にあるので、ロック解除動作を利用して当該上端面とフック部の接触を外し、蓋部分の上昇を許して静止段状部と係合端の引っ掛かりを実現することができる。 Further, when the increase in the internal pressure of the container main body exceeds the atmospheric pressure while the hook part is hooked on the hook receiving part, the hook part comes into contact with the upper end surface of the lid part excluding the hook part. The lid portion pushed by the internal pressure is prevented from rising, and the hook portion is shifted in the unlocking operation direction so that the stationary stepped portion faces the engagement end and the lid portion rises. Good. In this example, it is possible to prevent the lid from floating from the container main body due to an increase in the internal pressure of the container main body by contacting the upper end surface of the lid portion with the hook portion. For this reason, even if the internal pressure rises, the appearance of the sealed container does not deteriorate. When the internal pressure exceeds the atmospheric pressure above a certain level, it is in the blocking state.Therefore, the unlocking operation is used to remove the contact between the upper end surface and the hook part, and the lid part is allowed to rise to engage with the stationary stepped part. It is possible to realize catching at the end.

上述のように、この発明は、上記構成の採用により、密閉容器の容器本体に対して蓋を直線的な動きで着脱可能でありながら、フックとフック受部で蓋が容器本体の内圧で外れないようにすることができ、このようにしても、内圧が高い危険な状態では蓋のロック解除を阻止し、急な蓋の押し出しや内容物の飛び出しを防ぐことができる。 As described above, according to the present invention, by adopting the above configuration, the lid can be detached from the container body of the hermetic container by a linear movement, but the lid is detached by the internal pressure of the container body at the hook and the hook receiving portion. Even in this case, in a dangerous state where the internal pressure is high, it is possible to prevent the lid from being unlocked, and it is possible to prevent sudden pushing out of the lid and popping out of the contents.

以下、この発明の第１実施形態に係る密閉容器を添付図面に基いて説明する。図２、図３に示すように、この密閉容器は、容器本体１と、この容器本体１の口部２を密封する蓋３とを備えている。 Hereinafter, an airtight container according to a first embodiment of the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 2 and 3, the sealed container includes a container body 1 and a lid 3 that seals the mouth 2 of the container body 1.

容器本体１は、少なくとも内容物を入れる容器を含み、密閉容器の蓋を除いた部分のことをいう。例えば、容器本体１として、図示のようなポットの他、マグボトル、ランチボックスの汁容器等が挙げられる。容器本体１は、図２〜図４に示すように、内容物の給水口となる口部２をもった断熱容器４と、断熱容器４の肩部に被さる肩カバー部材５とをもっている。断熱容器４として、例えば、ステンレス製の真空二重容器、魔法瓶等を用いることができる。断熱容器４に代えて、真空層、断熱部材等の断熱手段をもたない剛性容器を採用してもよい。肩カバー部材５は、内容物の注ぎ口６と、ハンドル７とをもっている。 The container main body 1 includes a container for containing at least the contents, and refers to a portion excluding the lid of the sealed container. For example, as the container main body 1, besides a pot as illustrated, a mug bottle, a juice container of a lunch box, and the like can be cited. As shown in FIGS. 2 to 4, the container main body 1 has a heat insulating container 4 having a mouth portion 2 that serves as a water supply port for contents, and a shoulder cover member 5 that covers the shoulder portion of the heat insulating container 4. As the heat insulating container 4, for example, a stainless steel vacuum double container, a thermos bottle or the like can be used. Instead of the heat insulating container 4, a rigid container having no heat insulating means such as a vacuum layer or a heat insulating member may be adopted. The shoulder cover member 5 has a content spout 6 and a handle 7.

蓋３は、図２、図４、図５に示すように、直線移動で口部２から断熱容器４に対して抜き差しされる栓ユニット８と、栓ユニット８に被さるトップカバー９とを組み合わせた構造になっている。直線移動方向を図中に一点鎖線で描いた。一点鎖線は、断熱容器４の断面円形状の内周面と同一軸線上にある。栓ユニット８は、図２、図３、図５に示すように、断熱容器４の内周に密着する栓パッキン１０と、断熱容器４内から注ぎ口６まで連通する流路１１と、流路１１を開閉する弁と、内容物を注ぐときに使う操作レバー１２と、フック１３、１３と、ピニオン１４と、フック復帰ばね１５、１５と、レバー復帰ばね１６とをもっている。 As shown in FIGS. 2, 4, and 5, the lid 3 is a combination of a stopper unit 8 that is inserted into and removed from the heat insulating container 4 through the mouth portion 2 by linear movement and a top cover 9 that covers the stopper unit 8. It has a structure. The direction of linear movement is drawn with a dashed line in the figure. The alternate long and short dash line is on the same axis as the inner peripheral surface of the heat insulating container 4 having a circular cross section. 2, 3, and 5, the plug unit 8 includes a plug packing 10 that is in close contact with the inner periphery of the heat insulating container 4, a flow path 11 that communicates from the inside of the heat insulating container 4 to the spout 6, and a flow path 11, a valve 12 for opening and closing, an operation lever 12 used when pouring contents, hooks 13 and 13, a pinion 14, hook return springs 15 and 15, and a lever return spring 16.

前記弁は、図２、図３、図６に示すように、弁軸１７と、弁軸１７を軸方向に案内する弁軸ガイド１８と、弁体１９と、弁座２０と、弁ばね２１と、弁軸ばね２２と、弁ばね押さえ２３、弁軸ばね押さえ２４とからなる。弁軸ガイド１８、弁座２０、流路１１は、一体の下筒部材２５に形成されている。弁ばね押さえ２３と、下筒部材２５の上面との間に弁ばね２１が介在している。下筒部材２５の下面と弁体１９との間に弁軸ばね押さえ２４と、弁軸ばね２２が介在している。弁ばね２１、弁軸ばね２２が自然長のとき、弁軸１７は待ち受け位置にあり、弁体１９が弁座２０に密着し、前記弁は閉じた状態になっている。使用者が操作レバー１２のハンドル７側を押すと、傾いた操作レバー１２で弁軸１７の頭部を押すことができる。これにより、頭部を押された弁軸１７が軸方向に下降する。この下降中、弁軸１７に係止している弁ばね押さえ２３が一緒に下降し、弁ばね２１を圧縮し、また、弁軸１７に係止している弁軸ばね押さえ２４、これに押された弁軸ばね２２、弁体１９も一緒に下降する。弁体１９が下降すると弁座２０から浮き、前記弁が開いた状態になる。使用者が操作レバー１２を離すと、レバー復帰ばね１６によって操作レバー１２が待ち受け位置に戻り、弁軸１７が弁ばね押さえ２３から弁ばね２１の弾性回復力を受けて上昇し、待ち受け位置に復帰し、これにより、前記弁が閉じた状態になる。 As shown in FIGS. 2, 3, and 6, the valve includes a valve shaft 17, a valve shaft guide 18 that guides the valve shaft 17 in the axial direction, a valve body 19, a valve seat 20, and a valve spring 21.

A valve shaft spring retainer 24 and a valve shaft spring 22 are interposed between the lower surface of the lower cylinder member 25 and the valve body 19. When the valve spring 21 and the valve shaft spring 22 are of natural length, the valve shaft 17 is in the standby position, the valve body 19 is in close contact with the valve seat 20, and the valve is closed. When the user pushes the handle 7 side of the operation lever 12, the head of the valve shaft 17 can be pushed by the tilted operation lever 12. As a result, the valve shaft 17 whose head has been pressed descends in the axial direction. During this lowering, the valve spring retainer 23 locked to the valve shaft 17 is lowered together to compress the valve spring 21 and to the valve shaft spring retainer 24 locked to the valve shaft 17. The valve shaft spring 22 and the valve body 19 thus lowered are also lowered together. When the valve body 19 is lowered, it floats from the valve seat 20 and the valve is opened. When the user releases the operation lever 12, the operation lever 12 is returned to the standby position by the lever return spring 16, and the valve shaft 17 is lifted by the elastic restoring force of the valve spring 21 from the valve spring retainer 23 and returned to the standby position. As a result, the valve is closed.

Yes.

図３、図５に示すように、フック１３は、前述のフック部３６と、ロック解除動作のためにプッシュ面３１に与えられた操作力をフック部３６に伝える操作伝達部３８とを有する。操作伝達部３８は、プッシュ面３１及びラック部３２をもった操作部材３９と、フック部３６と進退方向に挟持する付勢ばね４０と、操作伝達部３８を下から支持する支持ばね４１とで構成されている。操作伝達部３８とフック部３６は、揺動軸４２と軸受部４３とで連結されている。 As shown in FIGS. 3 and 5, the hook 13 includes the above-described hook portion 36 and an operation transmitting portion 38 that transmits an operation force applied to the push surface 31 for the unlocking operation to the hook portion 36. The operation transmission part 38 includes an operation member 39 having the push surface 31 and the rack part 32, an urging spring 40 sandwiched in the forward and backward direction with the hook part 36, and a support spring 41 that supports the operation transmission part 38 from below. It is configured. The operation transmitting portion 38 and the hook portion 36 are connected by a swing shaft 42 and a bearing portion 43.

操作部材３９は、フック復帰ばね１５を保持するばね受部４４を有する。フック復帰ばね１５は、コイルばねになっている。付勢ばね４０は、コイルばねの軸線方向を進退方向に向け、ばね一端部をフック部３６のばね保持部に嵌合し、ばね他端部を操作部材３９のばね保持部に嵌合することによって挟持されている。支持ばね４１は、板ばねの両側を操作部材３９の挿入部に差し込み、この際、操作部材３９の鉤状部に支持ばね４１の孔が嵌ることで操作部材３９に保持されている。 The operation member 39 has a spring receiving portion 44 that holds the hook return spring 15. The hook return spring 15 is a coil spring. The urging spring 40 is configured so that the axial direction of the coil spring is directed in the forward / backward direction, one end of the spring is fitted to the spring holding part of the hook part 36, and the other end of the spring is fitted to the spring holding part of the operation member 39. It is pinched by. The support spring 41 is held by the operation member 39 by inserting both sides of the leaf spring into the insertion portion of the operation member 39, and at this time, a hole of the support spring 41 is fitted in the flange portion of the operation member 39.

揺動軸４２は、進退方向に直角な方向に沿った向きになっている。軸受部４３は、短軸長さが概ね丸軸状の揺動軸４２の外径に相当し、長軸が進退方向に沿った長孔状になっている。このため、揺動軸４２と軸受部４３は、フック受部３７及びフック部３６に対する操作伝達部３８の傾きを許し、また、操作伝達部３８とフック部３６の相対的な進退方向のスライドを許す。 The swing shaft 42 is oriented along a direction perpendicular to the forward / backward direction. The bearing portion 43 corresponds to the outer diameter of the oscillating shaft 42 having a substantially short shaft length in a short shaft shape, and the long shaft has a long hole shape along the forward / backward direction. For this reason, the swinging shaft 42 and the bearing portion 43 allow the operation transmitting portion 38 to be inclined with respect to the hook receiving portion 37 and the hook portion 36, and also allow the operation transmitting portion 38 and the hook portion 36 to slide relative to each other. forgive.

蓋３の直線方向回りの向きを後方突出部３４と切欠き部３５とが合う方向にして、蓋３の栓ユニット８側を口部２から前記直線方向に差し込むと、トップカバー９が肩カバー部材５に載る前に、フック部３６のテーパ状の滑り面４５がフック受部３７に当たり、この際の進退方向の分力で付勢ばね４０、フック復帰ばね１５が圧縮される。さらに差し込みが進んで、フック部３６がフック受部３７よりも低くなると、付勢ばね４０、フック復帰ばね１５の弾性回復によってフック１３が進出し、フック部３６がフック受部３７の下方に位置する。これにより、フック部３６とフック受部３７とによって蓋３が容器本体１にロックされた状態になる。この差し込みの間、図７（ａ）、（ｂ）に示すように、ラック部３２、３２とピニオン１４によって両フック１３、１３の同期した進退運動が成される。 When the direction around the linear direction of the lid 3 is set so that the rear protrusion 34 and the notch 35 are aligned, and the plug unit 8 side of the lid 3 is inserted in the linear direction from the mouth portion 2, the top cover 9 becomes the shoulder cover. Before being placed on the member 5, the tapered sliding surface 45 of the hook portion 36 hits the hook receiving portion 37, and the biasing spring 40 and the hook return spring 15 are compressed by the component force in the advancing and retreating direction at this time. When the insertion further proceeds and the hook portion 36 becomes lower than the hook receiving portion 37, the hook 13 advances by the elastic recovery of the biasing spring 40 and the hook return spring 15, and the hook portion 36 is positioned below the hook receiving portion 37. To do. Thereby, the lid 3 is locked to the container body 1 by the hook portion 36 and the hook receiving portion 37. During this insertion, as shown in FIGS. 7A and 7B, the rack portions 32 and 32 and the pinion 14 cause the hooks 13 and 13 to move forward and backward in synchronization.

図３に示すように蓋３が容器本体１にロックされた状態で、図２に示すように流路１１の出口路４６が注ぎ口６と一連になっている。すなわち、流路１１と注ぎ口６が連なることにより、容器本体１内と大気間に亘る全長の連通路４７が形成されている。操作レバー１２を押さない限り、前記弁は流路１１の入り口で連通路４７を閉じている。連通路４７は、操作レバー１２を押して前記弁を開いた状態のまま、この密閉容器全体を注ぎ口６の方へ傾けて容器本体１内から内容物をカップ等の外部へ注ぐための流路になる。 In the state where the lid 3 is locked to the container body 1 as shown in FIG. 3, the outlet path 46 of the flow path 11 is in series with the spout 6 as shown in FIG. 2. That is, the flow path 11 and the spout 6 are connected to form a full length communication passage 47 extending between the container body 1 and the atmosphere. As long as the operation lever 12 is not pushed, the valve closes the communication path 47 at the entrance of the flow path 11. The communication passage 47 is a flow path for pouring the contents from the inside of the container body 1 to the outside such as a cup by tilting the whole sealed container toward the spout 6 while pushing the operation lever 12 and opening the valve. become.

図８（ａ）に拡大して示すように、容器本体１の内圧（断熱容器４内の圧力）が大気圧の状態、かつフック部３６がフック受部３７の下方に位置し、フック受部３７に引っ掛かるロック状態では、フック部３６が図５に示す揺動軸４２、軸受部４３及び付勢ばね４０で操作伝達部３８に対して傾かないように支持され、図８（ａ）、（ｂ）に矢線Ｆで示すように、使用者がプッシュ面３１を押すロック解除操作を行っても、フック１３の最低所部である係合端４８が、支持ばね４１及びフック復帰ばね１５により、フックガイド部２７に対して所定の高さを下回らないように支持される。プッシュ面３１から操作伝達部３８に与えられた操作力は、フック復帰ばね１５を圧縮し、付勢ばね４０を介してフック部３６に伝わる。付勢ばね４０はあまり圧縮されず、操作伝達部３８とフック部３６が付勢ばね４０の抵抗で連動し、図８（ｂ）に示すようにフック部３６がフック受部３７から外れるまでフック部３６が後退する。これにより、蓋３を前記直線方向に沿った直線移動で容器本体１から引き抜くことが可能になる。このようにフック１３がロック解除動作しても、フック１３は、支持ばね４１、フック復帰ばね１５によってフックガイド部２７から所定の高さを下回らないように支持されるので、蓋３の静止段状部４９に引っ掛からない姿勢に保たれる。なお、このロック解除動作の間も両フック１３、１３の同期運動が成されることは勿論である。 As shown in an enlarged view in FIG. 8A, the internal pressure of the container body 1 (pressure in the heat insulating container 4) is at atmospheric pressure, and the hook portion 36 is located below the hook receiving portion 37. In the locked state that is hooked on 37, the hook portion 36 is supported by the swing shaft 42, the bearing portion 43, and the biasing spring 40 shown in FIG. Even if the user performs the unlocking operation of pushing the push surface 31 as indicated by the arrow F in b), the engagement end 48 which is the lowest part of the hook 13 is retained by the support spring 41 and the hook return spring 15. The hook guide portion 27 is supported so as not to fall below a predetermined height. The operating force applied from the push surface 31 to the operation transmitting portion 38 compresses the hook return spring 15 and is transmitted to the hook portion 36 via the biasing spring 40. The biasing spring 40 is not compressed so much that the operation transmitting portion 38 and the hook portion 36 are interlocked by the resistance of the biasing spring 40, and the hook portion 36 is hooked until it is detached from the hook receiving portion 37 as shown in FIG. Part 36 is retracted. As a result, the lid 3 can be pulled out of the container body 1 by linear movement along the linear direction. Even when the hook 13 is unlocked as described above, the hook 13 is supported by the support spring 41 and the hook return spring 15 so as not to fall below a predetermined height from the hook guide portion 27. The posture is maintained so as not to be caught by the shape portion 49. Of course, both hooks 13 and 13 are synchronized during the unlocking operation.

一方、フック部３６がフック受部３７の下方に位置し、フック受部３７に引っ掛かるロック状態で、容器本体１の内圧が大気圧を超えて上昇すると、図１（ａ）に拡大して示すように、フック１３が、当該内圧に抵抗することによって姿勢変化を起こす。すなわち、フック受部３７に引っ掛かるフック１３を除いた蓋３部分の上昇が起こる。この蓋３部分の上昇によって、操作伝達部３８と蓋３部分間に介在するフック復帰ばね１５が操作部材３９と反対側で持ち上げられ、支持ばね４１が下側へ圧縮されるので、揺動軸４２が軸受部４３に対して少し滑り、操作伝達部３８がフック受部３７に対して傾く。このように操作伝達部３８が傾いても、フック部３６は、フック受部３７に面接触しているので、殆ど傾かない。この蓋３部分の上昇と操作伝達部３８の傾きは、内圧上昇に伴って大きくなり、内圧減少に伴って小さくなる。また、蓋３部分の上昇によって、静止段状部４９が係合端４８に接近する。容器本体の内圧が大気圧を一定以上超えている状態では、係合端４８が静止段状部４９と進退方向に対向するまで、蓋３部分の上昇、操作伝達部３８の傾きが進行する。容器本体１の内圧が下降しない限り、蓋３部分の下降は起こらず、支持ばね４１やフック復帰ばね１５が弾性回復することはできない。したがって、容器本体１の内圧が大気圧を一定以上超えている状態では、フック１３がロック解除動作しても、フック部３６がフック受部３７から外れる以前に、フック部３６の係合端４８が静止段状部４９に進退方向に引っ掛かる。このように、この密閉容器は、内圧に抵抗するフック１３のうち、フック受部３７に引っ掛かるフック部３６の姿勢変化を避け、操作伝達部３８の傾きを利用して係合端４８と静止段状部４９の引っ掛かりを実現し、そのフック部３６のロック解除動作を静止段状部４９で直接に阻止することができる。 On the other hand, when the internal pressure of the container body 1 rises above the atmospheric pressure in a locked state where the hook portion 36 is located below the hook receiving portion 37 and is hooked on the hook receiving portion 37, the enlarged view is shown in FIG. As described above, the hook 13 changes its posture by resisting the internal pressure. That is, the lid 3 is lifted except for the hook 13 that is hooked on the hook receiving portion 37. As the lid 3 is raised, the hook return spring 15 interposed between the operation transmitting portion 38 and the lid 3 is lifted on the side opposite to the operating member 39, and the support spring 41 is compressed downward. 42 slides slightly with respect to the bearing portion 43, and the operation transmission portion 38 is inclined with respect to the hook receiving portion 37. Thus, even if the operation transmitting portion 38 is tilted, the hook portion 36 is hardly tilted because it is in surface contact with the hook receiving portion 37. The rise of the lid 3 portion and the inclination of the operation transmitting portion 38 increase as the internal pressure increases, and decrease as the internal pressure decreases. Further, the stationary stepped portion 49 approaches the engaging end 48 by raising the lid 3 portion. In a state where the internal pressure of the container main body exceeds the atmospheric pressure more than a certain level, the lid 3 part rises and the operation transmission part 38 tilts until the engagement end 48 faces the stationary stepped part 49 in the forward / backward direction. As long as the internal pressure of the container body 1 does not drop, the lid 3 does not drop, and the support spring 41 and the hook return spring 15 cannot be elastically recovered. Therefore, in a state where the internal pressure of the container body 1 exceeds the atmospheric pressure more than a certain level, even if the hook 13 is unlocked, the engagement end 48 of the hook portion 36 is removed before the hook portion 36 is detached from the hook receiving portion 37. Is caught on the stationary step portion 49 in the advancing and retracting direction. As described above, this sealed container avoids a change in the posture of the hook portion 36 that is hooked on the hook receiving portion 37 among the hooks 13 that resist internal pressure, and uses the inclination of the operation transmitting portion 38 and the stationary end 48 and the stationary stage. The hook portion 36 can be locked and the unlocking operation of the hook portion 36 can be directly prevented by the stationary step portion 49.

図１（ａ）の状態から使用者がロック解除操作を行うと、フック部３６の係合端４８が静止段状部４９に引っ掛かり、揺動軸４２が軸受部４３を進退方向に滑り、操作伝達部３８がフック部３６に対して進退方向にスライドする。このスライド中、操作伝達部３８は、停止しているフック部３６に向って付勢ばね４０を圧縮する。このため、付勢ばね４０が蓄勢する。したがって、操作伝達部３８に操作力が与えられなくなると、当該蓄勢力によって操作伝達部３８がスライド前の図１（ａ）の位置に復帰する。このように、この密閉容器は、係合端４８が静止段状部４９に引っ掛かったとき、操作伝達部３８だけがスライドするため、引っ掛かったままの強引なロック解除操作をスライドストロークで防ぎ、フック１３の傷みを防止することができる。また、使用者がロック解除操作を止めると、操作伝達部３８が自然とスライド前の位置に戻るため、次回のロック解除操作に支障はない。 When the user performs the unlocking operation from the state shown in FIG. 1A, the engaging end 48 of the hook portion 36 is caught by the stationary stepped portion 49, and the swing shaft 42 slides the bearing portion 43 in the forward / backward direction. The transmission part 38 slides in the forward / backward direction with respect to the hook part 36. During this sliding, the operation transmission portion 38 compresses the biasing spring 40 toward the hook portion 36 that is stopped. For this reason, the biasing spring 40 stores energy. Therefore, when the operation force is no longer applied to the operation transmission unit 38, the operation transmission unit 38 returns to the position shown in FIG. Thus, since this closed container only slides the operation transmitting portion 38 when the engaging end 48 is caught by the stationary stepped portion 49, the airtight container prevents the forceful unlocking operation while being caught by the slide stroke, Thirteen damages can be prevented. In addition, when the user stops the unlocking operation, the operation transmitting unit 38 naturally returns to the position before the slide, so that the next unlocking operation is not hindered.

操作伝達部３８がスライドしても、容器本体１の内圧が大気圧を一定以上超えている状態では、支持ばね４１やフック復帰ばね１５が弾性回復することはできず、軸受部４３が揺動軸４２を下側から支持するため、図１（ｂ）に示すように操作伝達部３８の傾きは小さくなるが、フック１３としては、依然、フック部３６の係合端４８が静止段状部４９に進退方向に引っ掛かる姿勢に保たれる。 Even if the operation transmitting portion 38 slides, the support spring 41 and the hook return spring 15 cannot be elastically recovered and the bearing portion 43 swings in a state where the internal pressure of the container body 1 exceeds the atmospheric pressure over a certain level. Since the shaft 42 is supported from the lower side, the inclination of the operation transmitting portion 38 is reduced as shown in FIG. 1B. However, as the hook 13, the engaging end 48 of the hook portion 36 is still the stationary stepped portion. 49 is kept in a posture of being caught in the forward / backward direction.

蓋３は、図１（ａ）、（ｂ）に示すように、前記ロック解除動作を前記弁の開弁動作に変換する連動機構を有する。この連動機構は、操作レバー１２と、フック１３とからなり、静止段状部４９に引っ掛かっているフック部３６に対してスライドする操作伝達部３８の運動を前記弁の開弁動作に変換する。スライドする操作伝達部３８の角部５０が、操作レバー１２のテーパ状の当り面５１に接触して下向きの分力が発生する。この分力が操作レバー１２を軸方向に押し下げ、操作レバー１２を介して弁軸１７に伝わった分力が弁ばね２１を圧縮し、これに伴って弁軸１７が軸方向に下降し、弁体１９が弁座２０から浮いて前記弁が開く。前記弁が開くと、図２の連通路４７から容器本体１の内圧を逃すことができる。なお、弁体１９に作用する断熱容器４の内圧が弁軸ばね２２の弾性力よりも強い場合、弁軸１７のみが下降し、弁体１９と弁軸１７間に生じた隙間から内圧が抜け、弁体１９に作用する内圧が弁軸ばね２２の弾性力よりも弱くなってくると、弁体１９が下降し、弁体１９と弁座２０間に生じた隙間からも内圧が抜ける。 As shown in FIGS. 1A and 1B, the lid 3 has an interlocking mechanism that converts the unlocking operation into the valve opening operation of the valve. This interlocking mechanism is composed of the operation lever 12 and the hook 13 and converts the motion of the operation transmitting portion 38 that slides with respect to the hook portion 36 hooked on the stationary stepped portion 49 into the valve opening operation of the valve. The corner portion 50 of the sliding operation transmitting portion 38 comes into contact with the tapered contact surface 51 of the operating lever 12 and a downward component force is generated. This component force pushes down the operating lever 12 in the axial direction, and the component force transmitted to the valve shaft 17 via the operating lever 12 compresses the valve spring 21. As a result, the valve shaft 17 descends in the axial direction. The body 19 floats from the valve seat 20 and the valve opens. When the valve is opened, the internal pressure of the container body 1 can be released from the communication passage 47 in FIG. When the internal pressure of the heat insulating container 4 acting on the valve body 19 is stronger than the elastic force of the valve shaft spring 22, only the valve shaft 17 is lowered and the internal pressure is released from the gap generated between the valve body 19 and the valve shaft 17. When the internal pressure acting on the valve body 19 becomes weaker than the elastic force of the valve shaft spring 22, the valve body 19 descends and the internal pressure is also released from the gap formed between the valve body 19 and the valve seat 20.

図１（ａ）に示すように、蓋３がロックされ、前記弁が閉じているとき、角部５０は、当り面５１の直近に待機している。この待機時、角部５０と当り面５１間の進退方向の距離は、フック受部３７とフック部３６の進退方向の掛かり代よりも明らかに小さい。使用者がプッシュ面３１を押してロック解除操作を開始すると、角部５０が速やかに操作レバー１２を押し始める。図１（ｂ）に示すように操作伝達部３８を限界まで押し切っても、角部５０が当り面５１を押し続けるため、前記弁も開き続ける。したがって、操作伝達部３８に操作力を与え続けると、図１（ａ）に示す容器本体１の内圧を図１（ｃ）に示すように大気圧まで減圧することができる。これにより、図１（ａ）のフック１３を除いた蓋３部分は、図１（ｃ）に示すように角部５０に操作レバー１２が押されることで下降させられ、支持ばね４１やフック復帰ばね１５の弾性回復が起きて、フック１３は、係合端４８が静止段状部４９に引っ掛からない状態に戻る。使用者が図１（ｃ）の状態で一旦ロック解除操作を止めると、操作伝達部３８が付勢ばね４０で図８（ａ）の位置へ復帰させられる。この後、使用者が再びロック解除操作を行えば、今度は係合端４８が静止段状部４９に引っ掛からないので、フック部３６がフック受部３７から外れ、蓋３を引き抜くことが可能になる。なお、連通路４７の前記弁よりも大気側に付着していた内容物は、大気に熱を奪われて冷めているので、減圧中に飛び出しても危険性はない。断熱容器４の内壁面に付着している内容物は、連通路４７に入り込んだとしても、連通路４７は大気に出るまでに複雑に曲がっているので、連通路４７の壁面で捕捉でき、減圧中に連通路４７から飛び出す心配はない。 As shown in FIG. 1A, when the lid 3 is locked and the valve is closed, the corner portion 50 stands by in the immediate vicinity of the contact surface 51. During this standby, the distance in the advancing / retreating direction between the corner portion 50 and the contact surface 51 is clearly smaller than the hook allowance of the hook receiving portion 37 and the hook portion 36 in the advancing / retreating direction. When the user presses the push surface 31 to start the unlocking operation, the corner portion 50 immediately starts to push the operation lever 12. As shown in FIG. 1B, even if the operation transmitting portion 38 is pushed all the way to the limit, the corner portion 50 continues to push the contact surface 51, so the valve continues to open. Therefore, when the operation force is continuously applied to the operation transmission unit 38, the internal pressure of the container body 1 shown in FIG. 1A can be reduced to the atmospheric pressure as shown in FIG. 1C. As a result, the lid 3 portion excluding the hook 13 in FIG. 1A is lowered when the operating lever 12 is pressed against the corner portion 50 as shown in FIG. When the elastic recovery of the spring 15 occurs, the hook 13 returns to a state where the engagement end 48 is not caught by the stationary step portion 49. Once the user stops the unlocking operation in the state shown in FIG. 1C, the operation transmitting portion 38 is returned to the position shown in FIG. Thereafter, when the user performs the unlocking operation again, the engaging end 48 is not caught by the stationary stepped portion 49, so that the hook portion 36 can be detached from the hook receiving portion 37 and the lid 3 can be pulled out. Become. In addition, since the contents adhering to the atmosphere side from the valve of the communication passage 47 are cooled by the air being deprived of heat, there is no danger even if they jump out during decompression. Even if the contents adhering to the inner wall surface of the heat insulating container 4 enter the communication passage 47, the communication passage 47 is bent in a complicated manner until it enters the atmosphere. There is no worry of jumping out from the communication passage 47 inside.

上述のように、この密閉容器は、容器本体１に対して蓋３を直線的な動きで着脱可能でありながら、フック１３とフック受部３７で蓋３が容器本体１の内圧で外れないようにすることができ、このようにしても、内圧が高い危険な状態では蓋３のロック解除を阻止し、急な蓋３の押し出しや内容物の飛び出しを防ぐことができる。また、この密閉容器は、図２に示す連通路４７及び前記弁が内圧逃し用と、内容物注ぎ用を兼ねているので、蓋３の構造複雑化を防止することができる。また、この密閉容器は、連動機構を図１（ａ）、（ｂ）に示すように蓋３のロックに必要なフック１３と、内容物を注ぐのに必要な操作レバー１２とで構成しているので、変換専用の他部材を蓋３に組み込むことがなく、これによっても蓋３の構造複雑化を防止することができる。 As described above, in this sealed container, the lid 3 can be attached to and detached from the container main body 1 by a linear movement, but the lid 3 does not come off by the internal pressure of the container main body 1 by the hook 13 and the hook receiving portion 37. Even in such a case, in a dangerous state where the internal pressure is high, the unlocking of the lid 3 can be prevented, and the sudden extrusion of the lid 3 and the jumping out of the contents can be prevented. Further, in this sealed container, since the communication passage 47 and the valve shown in FIG. 2 serve both for internal pressure relief and for content pouring, the structure of the lid 3 can be prevented from becoming complicated. In addition, as shown in FIGS. 1 (a) and 1 (b), the airtight container is configured by a hook 13 necessary for locking the lid 3 and an operation lever 12 necessary for pouring the contents. Therefore, the other member dedicated for conversion is not incorporated into the lid 3, and this can also prevent the lid 3 from being complicated.

この発明の第２実施形態を図９に基いて説明する。なお、以下、第１実施形態との相違点を説明するに留める。第２実施形態では、図９（ａ）に示すように、フック部３６がフック受部３７に引っ掛かる状態で容器本体１の内圧上昇が大気圧を超えて進行すると、フック１３を除いた蓋２部分の上端面５２とフック部３６が接触することによって蓋３部分の上昇が阻止される。静止段状部４９は、上端面５２から低くなった凹所の内側に位置している。係合端４８は、上端面５２との接触面から高く繋がっている。このため、容器本体１の内圧が大気圧を一定以上超えているとき、フック部３６がロック解除動作する方向にずれることによって、図９（ｂ）に示すように、係合端４８が凹所内に入り込み、これに伴って内圧に押される蓋３部分の急な上昇が起こり、静止段状部４９が係合端４８に進退方向に対向する。したがって、トップカバー９は、図９（ａ）に示すように、容器本体１の内圧が上昇しても、肩カバー部材５から浮き上がらず、内圧上昇中の密閉容器使用状態の見栄えが悪化しない。 A second embodiment of the present invention will be described with reference to FIG. Hereinafter, only differences from the first embodiment will be described. In the second embodiment, as shown in FIG. 9A, when the increase in the internal pressure of the container main body 1 exceeds the atmospheric pressure in a state where the hook portion 36 is hooked on the hook receiving portion 37, the lid 2 excluding the hook 13 is removed. When the upper end surface 52 of the portion comes into contact with the hook portion 36, the lid 3 is prevented from rising. The stationary step portion 49 is located inside the recess that is lowered from the upper end surface 52. The engagement end 48 is connected to a high level from the contact surface with the upper end surface 52. For this reason, when the internal pressure of the container body 1 exceeds the atmospheric pressure over a certain level, the hook portion 36 is displaced in the unlocking direction, so that the engagement end 48 is in the recess as shown in FIG. As a result, the lid 3 portion that is pushed by the internal pressure suddenly rises, and the stationary step portion 49 opposes the engagement end 48 in the forward / backward direction. Therefore, as shown in FIG. 9A, the top cover 9 does not rise from the shoulder cover member 5 even when the internal pressure of the container body 1 increases, and the appearance of the closed container in use while the internal pressure is increasing does not deteriorate.

上述の実施形態では、弁軸と弁体が独立した例を示したが、弁軸と弁体が一体になっているものでもよい。内容物流路用の弁と減圧用の弁の兼用例を示したが、減圧用の弁を別途に設けてもよい。例えば、特許文献１のように弁軸の中に減圧用の弁の弁軸や圧力逃し路を通し、フックで内容物流路用の弁軸又は操作レバーを押す前に、減圧用の弁軸を押し、その後、内容物流路用の弁軸又は操作レバーを押すようにすることができる。また、この実施形態ではフックが操作レバーを介して弁軸を押すようにしたが、兼用例にする場合、フックが直接に弁軸を押すようにすることもできる。例えば、操作レバー１２の揺動軸の高さをより上に設定できる場合、弁軸１７をさらに上方へ延長し、当り面５１で押す角部５０相当箇所を弁軸１７に設ければ、フック１３が直接に弁軸１７を押すようにすることができる。この発明の技術的範囲は、上述の態様に限定されず、特許請求の範囲の記載に基く技術的思想の範囲内での全ての変更を含むものである。 In the above-described embodiment, an example in which the valve shaft and the valve body are independent has been described. However, the valve shaft and the valve body may be integrated. Although the example of the contents flow path valve and the pressure reducing valve has been described, a pressure reducing valve may be provided separately. For example, as in Patent Document 1, a valve shaft for pressure reduction or a pressure relief passage is passed through the valve shaft, and before the valve shaft for content passage or the operation lever is pushed with a hook, the valve shaft for pressure reduction is inserted. Then, the valve shaft or the operation lever for the content flow path can be pushed. Further, in this embodiment, the hook pushes the valve shaft via the operation lever. However, in the combined example, the hook can also push the valve shaft directly. For example, when the height of the swing shaft of the operating lever 12 can be set higher, if the valve shaft 17 is further extended upward and the corner portion 50 corresponding to the pressing surface 51 is provided on the valve shaft 17, the hook 13 can push the valve shaft 17 directly. The technical scope of the present invention is not limited to the above-described embodiment, but includes all modifications within the scope of the technical idea based on the description of the scope of claims.
