Abstract

PROBLEM TO BE SOLVED: To attach/detach a lid to/from a vessel body of a closed vessel with linear line-like motion while preventing detachment of the lid even internal pressure of the vessel body presses the lid.SOLUTION: By lock release operation that a hook member 13 incorporated to a lid 3 is released from a hook reception part 37 of a vessel body 1, the lid 3 is pulled out from the vessel body 1 by linear line-like movement. And the lid 3 has a valve for opening/closing a communication path 40 over the inside of the vessel body 1 and room air, and an interlock mechanism which converts lock release operation into valve opening operation of the valve. When lock release operation starts, the valve opens before the hook member 13 is released from the hook reception part 37, and internal pressure inside the vessel body 1 which exceeds air pressure is released into room air through the communication path 40.

Description

この発明は、内容物を密閉空間に蓄える密閉容器に関する。 The present invention relates to a sealed container that stores contents in a sealed space.

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 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.

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部材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 body and a lid for sealing the mouth of the container body, includes a hook member incorporated in the lid. 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 comes off the part has been 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、密閉容器に熱い内容物を蓄えて時間が経過した後で蓋を外す際、フック部材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。 However, when the prototype is made, when the lid is removed after the hot contents have been stored in the sealed container and the time has elapsed, the lid suddenly stops due to the internal pressure of the container body exceeding the atmospheric pressure immediately after the hook member is removed from the hook receiving portion. In addition, it was found that the contents attached to the inner wall surface of the container main body may be carried out by being blown out under reduced pressure and may be ejected. 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.

そこで、この発明は、前記蓋の着脱・ロック構造と共に、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とを有し、前記ロック解除動作が始まると、前記フック部材が前記フック受部から外れる前に前記弁が前記連動機構の変換によって開き、前記容器本体の内圧が大気圧を上回る状態では当該内圧が前記連通路から大気に逃げる構成の採用により、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、フック部材とフック受部で蓋が容器本体の内圧で外れないようにしつつ、内圧上昇状態で蓋のロックを解除した際の急な蓋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。 Accordingly, the present invention converts the lid opening / closing operation into a valve opening operation of the valve, together with the lid attaching / detaching / locking structure, the lid opening and closing the communication path between the inside of the container body and the atmosphere. When the unlocking operation is started, the valve is opened by the conversion of the interlocking mechanism before the hook member is detached from the hook receiving portion, and the internal pressure of the container body exceeds the atmospheric pressure. By adopting a configuration in which the internal pressure escapes from the communication path to the atmosphere, the lid can be attached to and detached from the container body by a linear movement, but the lid does not come off by the internal pressure of the container body at the hook member and the hook receiving portion. In the meantime, it was made possible to prevent sudden lid push-out and contents pop-out when the lid was unlocked with the internal pressure increased.

前記連通路が前記容器本体内の内容物を注ぐための流路からなることが好ましい。この場合、内圧逃し用の前記連通路及び弁と、内容物を注ぎ用の流路及び弁を兼用化しているので、蓋の構造複雑化を防止することができる。 It is preferable that the communication path includes a flow path for pouring the contents in the container body. In this case, since the communication passage and valve for releasing internal pressure and the flow path and valve for pouring the contents are used in common, the structure of the lid can be prevented from becoming complicated.

特に、前記蓋が、容器本体内の内容物を注ぐときに使う操作レバーを有し、前記連動機構が、前記フック受部から外れる方向に移動している前記フック部材で直接に前記操作レバーを軸方向に押すことによって、ロック解除動作を開弁動作に変換することが好ましい。この場合、連動機構を蓋のロックに必要なフック部材と、内容物を注ぐのに必要な操作レバーとで構成しているので、変換専用の他部材を蓋に組み込むことがなく、蓋の構造複雑化を防止することができる。 In particular, the lid has an operation lever that is used when pouring the contents in the container body, and the interlock mechanism moves the operation lever directly with the hook member that is moving away from the hook receiving portion. It is preferable to convert the unlocking operation into the valve opening operation by pushing in the axial direction. In this case, since the interlocking mechanism is composed of a hook member necessary for locking the lid and an operation lever necessary for pouring the contents, the structure of the lid can be obtained without incorporating other members dedicated to conversion into the lid. Complexity can be prevented.

上述のように、この発明は、上記構成の採用により、フック部材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、内圧上昇状態で蓋のロックを解除した際の急な蓋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, by adopting the above configuration, the present invention can prevent the lid from being removed by the internal pressure of the container body at the hook member and the hook receiving portion. When the lock is released, sudden lid push-out and contents pop-out can be prevented.

以下、この発明の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 an 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。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。 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. 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. As the heat insulating container 4, for example, a stainless steel vacuum double container, a thermos bottle or the like can be used.

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、フック部材１３、１３と、ピニオン１４、フック復帰ばね１５、１５、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, an operation lever 12 used when pouring contents, hook members 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. And a valve shaft spring 22, a valve spring retainer 23, and a valve shaft spring retainer 24. The valve shaft guide 18, the valve seat 20, and the flow path 11 are formed in an integrated lower cylinder member 25. A valve spring 21 is interposed between the valve spring retainer 23 and the upper surface of the lower cylinder member 25. 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.

図２、図５、図６に示すように、操作レバー１２の揺動軸を支持する軸受部２６、フック部材１３を弁軸ガイド１８と直角な進退方向に案内するフックガイド部２７、フック部材１３と共にフック復帰ばね１５、１５を保持するばね受部２８、ピニオン１４の旋回支持部２９は、一体の栓カバー部材３０の上面に形成されている。図５に示すように、フック部材１３は、プッシュ面３１と、ラック部３２とをもっている。図６に示す栓カバー部材３０と下筒部材２５を図５に示すように係合し、さらに栓カバー部材３０にトップカバー９を被せてねじ止めすると、図２〜図４に示すように、フック部材１３等が組み込まれた蓋３になる。図３、図４に示すように、トップカバー９の上面には、フック部材１３のプッシュ面３１を押すロック解除操作を実施するための凹み孔３３が形成されている。 As shown in FIGS. 2, 5, and 6, a bearing portion 26 that supports the swing shaft of the operation lever 12, a hook guide portion 27 that guides the hook member 13 in a forward and backward direction perpendicular to the valve shaft guide 18, and a hook member 13, the spring receiving portion 28 that holds the hook return springs 15, 15 and the turning support portion 29 of the pinion 14 are formed on the upper surface of the integral plug cover member 30. As shown in FIG. 5, the hook member 13 has a push surface 31 and a rack portion 32. When the stopper cover member 30 and the lower cylinder member 25 shown in FIG. 6 are engaged as shown in FIG. 5 and the top cover 9 is put on the stopper cover member 30 and screwed, as shown in FIGS. The lid 3 incorporates the hook member 13 and the like. As shown in FIGS. 3 and 4, a recess 33 is formed in the upper surface of the top cover 9 for performing an unlocking operation for pressing the push surface 31 of the hook member 13.

図３、図４に示すように、肩カバー部材５は、トップカバー９の後方突出部３４が嵌る切欠き部３５と、フック部材１３のフック部３６が前記直線方向に引っ掛かるフック受部３７とをもっている。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、フック部材１３のテーパ状の滑り面３８がフック受部３７に当たり、この際の進退方向の分力でフック復帰ばね１５が圧縮される。さらに差し込みが進んで、フック部材１３がフック受部３７よりも低くなると、フック復帰ばね１５の弾性回復によってフック部材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によって両フック部材１３、１３の同期した進退運動が成される。 As shown in FIGS. 3 and 4, the shoulder cover member 5 includes a notch portion 35 into which the rearward projecting portion 34 of the top cover 9 is fitted, and a hook receiving portion 37 in which the hook portion 36 of the hook member 13 is hooked in the linear direction. Have 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 38 of the hook member 13 hits the hook receiving portion 37, and the hook return spring 15 is compressed by the component force in the forward / backward direction at this time. When the insertion further proceeds and the hook member 13 becomes lower than the hook receiving portion 37, the hook member 13 advances by the elastic recovery of the hook return spring 15, and the hook portion 36 is positioned below the hook receiving portion 37. 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 hook members 13 and 13 to move forward and backward in synchronization.

図３の状態から使用者が図１（ａ）に示すようにフック部材１３のプッシュ面３１を押すロック解除操作によって、フック復帰ばね１５が負けて圧縮され、図１（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材１３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。なお、このロック解除動作の間も両フック部材１３、１３の同期運動が成されることは勿論である。 As shown in FIG. 1B, the hook return spring 15 is lost and compressed by the unlocking operation in which the user pushes the push surface 31 of the hook member 13 as shown in FIG. The hook member 13 is retracted until the hook portion 36 is detached from the hook receiving portion 37. As a result, the lid 3 can be pulled out of the container body 1 by linear movement along the linear direction. Needless to say, both hook members 13 and 13 are synchronized during the unlocking operation.

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３９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４０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４０を閉じている。連通路４０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 39 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 path 40 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 40 at the entrance of the flow path 11. The communication path 40 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.

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、フック部材１３とからなる。図１（ａ）に示すように、ロック解除操作によってフック受部３７から外れる方向に移動しているフック部材１３のテーパ状の当り面４１が、操作レバー１２の角部４２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。さらにロック解除動作が進むと、図１（ｂ）に示すように、角部４２が当り面４１よりも低くなり、フック部材１３が操作レバー１２の上を進退方向に進み、前記弁が最も開いた状態になる。このように、この連動機構は、フック受部３７から外れる方向に移動しているフック部材１３で直接に操作レバー１２を軸方向に押すことによって、ロック解除動作を開弁動作に変換することができる。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 includes an operation lever 12 and a hook member 13. As shown in FIG. 1A, the tapered contact surface 41 of the hook member 13 that moves in a direction away from the hook receiving portion 37 by the unlocking operation contacts the corner portion 42 of the operating lever 12 and faces downward. The component force of 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 unlocking operation further proceeds, as shown in FIG. 1B, the corner portion 42 becomes lower than the contact surface 41, the hook member 13 advances in the forward / backward direction on the operation lever 12, and the valve opens most. It becomes a state. In this way, this interlocking mechanism can convert the unlocking operation into the valve opening operation by directly pushing the operating lever 12 in the axial direction with the hook member 13 moving in the direction away from the hook receiving portion 37. it can. 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３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、当り面４１は、操作レバー１２の角部４２の直近に待機している。この待機時、当り面４１と角部４２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。使用者がフック部材１３のプッシュ面３１を押してロック解除操作を開始すると、図１（ａ）に示すように当り面４１が速やかに操作レバー１２を押し始め、フック部材１３のフック部３６がフック受部３７の下方から外れる前に、前記弁が前記連動機構の変換によって開く。 As shown in FIG. 3, when the lid 3 is locked and the valve is closed, the contact surface 41 stands by in the immediate vicinity of the corner 42 of the operation lever 12. During this standby, the distance in the advancing / retreating direction between the contact surface 41 and the corner 42 is obviously smaller than the hook allowance of the hook receiving part 37 and the hook part 36 in the advancing / retreating direction. When the user starts the unlocking operation by pressing the push surface 31 of the hook member 13, the contact surface 41 immediately starts to press the operation lever 12 as shown in FIG. 1A, and the hook portion 36 of the hook member 13 is hooked. Before coming off from below the receiving portion 37, the valve is opened by conversion of the interlocking mechanism.

容器本体１の断熱容器４内に熱い内容物を蓄えて時間が経過すると、外部からの加熱がなくとも、断熱容器４の内圧が大気圧を上回る。この状態で使用者が蓋３を容器本体１から外す際、ロック解除操作を開始すると、フック部３６がフック受部３７の下方から外れる前に、前記弁が開き、断熱容器４の内圧が図２に示す連通路４０から大気に逃げる。 When hot contents are stored in the heat insulating container 4 of the container main body 1 and time elapses, the internal pressure of the heat insulating container 4 exceeds the atmospheric pressure without any external heating. When the user starts the unlocking operation when removing the lid 3 from the container body 1 in this state, the valve is opened before the hook part 36 is released from the lower side of the hook receiving part 37, and the internal pressure of the heat insulating container 4 is reduced. Escape to the atmosphere from the communication path 40 shown in FIG.

したがって、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、蓋３が容器本体１の断熱容器４の内圧で外れないようにすることができる。また、容器本体１の内圧が大気圧を上回る状態では、図１（ｂ）に示すようにフック部３６がフック受部３７から外れた蓋３のロック解除時点で既に断熱容器４の内圧が減圧されているので、蓋３が急に押し出されたり、断熱容器４の内壁面に付着している内容物が飛び出したりする現象を防ぐこともできる。さらに、この密閉容器は、図２に示す連通路４０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。さらに、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部材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。 Therefore, this sealed container can prevent the lid 3 from being removed by the internal pressure of the heat insulating container 4 of the container body 1 while the lid 3 can be attached to and detached from the container body 1 by linear movement. In the state where the internal pressure of the container body 1 exceeds the atmospheric pressure, the internal pressure of the heat insulating container 4 has already been reduced when the lid 3 is unlocked when the hook portion 36 is detached from the hook receiving portion 37 as shown in FIG. Therefore, the phenomenon that the lid 3 is suddenly pushed out or the contents attached to the inner wall surface of the heat insulating container 4 jump out can be prevented. Further, in this sealed container, since the communication passage 40 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, this closed container has an interlocking mechanism composed of a hook member 13 necessary for locking the lid 3 and an operation lever 12 necessary for pouring the contents as shown in FIGS. 1 (a) and 1 (b). Therefore, other members dedicated to conversion are not incorporated into the lid, and this also prevents the lid 3 from being complicated.

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。一般的な断熱容器４の断熱性能からすると、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い。したがって、１００℃の内容物を断熱容器４に満たして標準大気圧、２０℃の雰囲気下での放置時間が６時間以内の条件下で断熱容器４の内圧が最も高いときに蓋３を外す際、フック部３６がフック受部３７から外れた時点で前述の減圧性能を達成できることが好ましく、理想的には大気圧まで減圧できることが好ましい。 In addition, when using hot food and drink as a pot, the temperature is 65 to 100 degreeC. Considering the heat insulating performance of a general heat insulating container 4, the internal pressure does not become a problem because the temperature of the contents decreases after 6 hours. Therefore, when the heat insulation container 4 is filled with the content of 100 ° C., the lid 3 is removed when the internal pressure of the heat insulation container 4 is the highest under the condition that the standing time in the atmosphere of standard atmospheric pressure and 20 ° C. is within 6 hours. It is preferable that the pressure reducing performance described above can be achieved when the hook portion 36 is detached from the hook receiving portion 37, and ideally, the pressure can be reduced to atmospheric pressure.

連通路４０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４０に入り込んだとしても、連通路４０は大気に出るまでに複雑に曲がっているので、連通路４０の壁面で捕捉でき、減圧中に連通路４０から飛び出す心配はない。 Since the contents adhering to the atmosphere side of the valve of the communication path 40 are cooled by the heat being taken away by the atmosphere, 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 path 40, the communication path 40 is bent in a complicated manner until it enters the atmosphere. There is no worry of jumping out of the communication path 40 inside.

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。また、この実施形態ではフック部材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、フック部材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４１で押す角部４２相当箇所を弁軸１７に設ければ、フック部材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 embodiment, an example in which the valve shaft and the valve body are independent is shown, but the valve shaft and the valve body may be integrated. Further, in this embodiment, the hook member pushes the valve shaft via the operation lever. However, in the combined example, the hook member can push the valve shaft directly. For example, if the height of the swing shaft of the operating lever 12 can be set higher, the valve shaft 17 can be further extended upward, and the corner corresponding to the corner portion 42 pressed by the contact surface 41 can be provided on the valve shaft 17. The member 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.
