Description

本発明は、エアーポットなどの加圧注出式液体容器に関するものである。 The present invention relates to a pressure dispensing liquid container such as an air pot.

この種の加圧注出式液体容器では、容器本体内部に熱い飲料を入れ、蓋を閉めた直後に本体を激しく振るなどして容器内の圧力が上がったとき、圧力を下げるために蒸気孔が設けられているが、中栓の蒸気孔が小さいと、容器内の圧力が抜けにくくなるため、吐出口から内容液が出やすくなるという問題がある。さらにこの蒸気孔からの転倒時流水を防ぐために蒸気孔を塞ぐ目的で弁体が配置されるのが一般的である。   In this type of pressurized pour-out type liquid container, when a hot beverage is put inside the container body, and the pressure in the container rises by shaking the body vigorously immediately after closing the lid, a vapor hole is formed to reduce the pressure. Although it is provided, if the steam hole of the inner plug is small, it is difficult to release the pressure in the container, so that there is a problem that the content liquid is easily discharged from the discharge port. Further, in order to prevent the flowing water from falling from the steam hole, a valve body is generally arranged for the purpose of closing the steam hole.

図９は従来の弁構造の一例を示し、前記圧力が抜けにくくなる問題を解決するためには、蒸気孔101を大きくすればよいが、図９のような通常使用されている円錐形状の弁体102では、蒸気孔101の径ｄ１が大きくなれば弁体102の径ｄ２と高さも大きくしなければならない。しかし、中栓内には吐出孔や空気送入孔などがあるため、弁体102を大きくするスペースがなく、弁体102を大きくするには容器本体の口径を広くして中栓の径を大きくする必要があり、口径を広くすると保温性能の低下を招き、仮に弁体102を大きくしてもコストも高くなる。また、円錐形状の弁体102では、弁体102を支える支持リブや中栓蒸気孔の成形時の変形等により転倒時に蒸気孔101と弁体102の間に隙間ができ、蒸気孔101が弁体102で塞がらず、止水できない場合がある。一方、球体の弁体（図示せず）だけでは倒した時蒸気孔が移動しないため弁体が蒸気孔を塞ぐことができず、確実に蒸気孔を塞ぐことができない。   FIG. 9 shows an example of a conventional valve structure, and in order to solve the problem that the pressure is difficult to escape, the steam hole 101 may be enlarged. In the body 102, if the diameter d1 of the steam hole 101 is increased, the diameter d2 and height of the valve body 102 must be increased. However, since there are discharge holes and air inlet holes in the inside plug, there is no space for enlarging the valve body 102. To enlarge the valve body 102, the diameter of the container body is increased by increasing the diameter of the container body. It is necessary to increase the diameter, and if the diameter is increased, the heat retention performance is lowered. Even if the valve body 102 is enlarged, the cost increases. Further, in the conical valve body 102, a gap is formed between the steam hole 101 and the valve body 102 at the time of overturning due to deformation or the like of the support rib supporting the valve body 102 or the inner plug steam hole, and the steam hole 101 is a valve. There are cases where the body 102 is not blocked and the water cannot be stopped. On the other hand, since the steam hole does not move when it is tilted only with a spherical valve body (not shown), the valve body cannot block the steam hole and cannot reliably block the steam hole.

また、弁体内に蛇腹形状のベローズを備えた一般的なエアーポットにおいては、転倒した際には蓋体内部にあるベローズの内部にまで内溶液が入る構造となっているため、ベローズ内部が濡れて汚れるという問題もある。   In general air pots with bellows-shaped bellows in the valve body, the internal solution enters the inside of the bellows inside the lid when it falls, so the inside of the bellows gets wet. There is also the problem of getting dirty.

特開２０１１−１９４１５９号公報JP 2011-194159 A

解決しようとする問題点は、弁体を大きくすることなく、転倒時に内部の液体を流出し難くする構造を提供する点である。   The problem to be solved is to provide a structure that makes it difficult for the liquid inside to flow out during a fall without increasing the size of the valve body.

請求項１の発明は、液体を収納する上端が開口した容器本体と、この容器本体の上開口部に着脱可能に装着すると共に前記容器本体内と外部とを連通させる蒸気孔を有した中栓と、前記容器本体の上部に開閉可能に配置した蓋体とを備えた加圧注出式液体容器において、前記中栓に設けられ転倒時に液体が外部に流出し難くする球体の弁体と、前記弁体の上部に設けられ転倒時に転倒方向に移動する可動板と、前記弁体より小さい直径で前記可動板に設けられ前記弁体が係入する係合孔とを備えることを特徴とする。   The invention according to claim 1 is a container main body having an open upper end for storing a liquid, and an inner plug having a vapor hole that is detachably attached to the upper opening of the container main body and communicates the inside of the container main body with the outside. And a pressure pouring type liquid container provided with an openable and closable lid on the upper part of the container body, the spherical valve body provided on the inner plug and making it difficult for the liquid to flow to the outside when falling, and A movable plate provided on an upper portion of the valve body and moving in the direction of falling when the valve body falls, and an engagement hole provided in the movable plate with a smaller diameter than the valve body and into which the valve body is engaged.

請求項２の発明は、前記可動板が円盤状となっていることを特徴とする。   The invention of claim 2 is characterized in that the movable plate has a disk shape.

請求項３の発明は、前記可動板の前記係合孔が前記蒸気孔より小さいことを特徴とする。   The invention of claim 3 is characterized in that the engagement hole of the movable plate is smaller than the vapor hole.

請求項４の発明は前記可動板が端まで移動しても前記可動板の係合孔が蒸気孔の面積内に収まることを特徴とする。   According to a fourth aspect of the present invention, the engagement hole of the movable plate is within the area of the steam hole even when the movable plate moves to the end.

請求項５の発明は、前記蒸気孔の周囲に前記可動板と該蒸気孔の周囲が線接触となるような突起を設けたことを特徴とする。   The invention of claim 5 is characterized in that a projection is provided around the vapor hole so that the movable plate and the vapor hole are in line contact with each other.

請求項６の発明は、前記可動板が金属製であることを特徴とする。   The invention of claim 6 is characterized in that the movable plate is made of metal.

請求項１の発明によれば、中栓内部に転倒時に液体が外部に漏れ難くする球体の弁体と、この弁体の上部に転倒時に転倒方向に移動し前記弁体より小さい直径の係合孔を有し弁体が入り込むような可動板を設けたことにより、容器本体内の圧力が高くなっても直ぐに圧力が抜ける十分な大きさの中栓蒸気孔を確保できると共に、弁体を大きくすることなく省スペース・低コストで転倒時に内部の液体が外部に流入し難くなる構造を提供できる。   According to the first aspect of the present invention, a spherical valve element that makes it difficult for liquid to leak to the outside when falling down inside the inner plug, and an engagement with a smaller diameter than the valve element that moves in the falling direction when falling over the valve body. By providing a movable plate with a hole that allows the valve body to enter, it is possible to secure a sufficiently large inside plug steam hole that can quickly release pressure even when the pressure in the container body increases, and the valve body can be made larger. Therefore, it is possible to provide a structure that makes it difficult for the liquid inside to flow into the outside at the time of falling without saving space and cost.

また、一般的なエアーポットにおいても、ベローズ内に内部の液体が入り難くなり、内部が汚れにくくなる。   Further, even in a general air pot, it becomes difficult for the liquid inside to enter the bellows, and the inside becomes difficult to get dirty.

請求項２の発明によれば、可動板が円盤状となっていることにより、どの方向に転倒しても、転倒方向に可動板が移動して弁体が可動板の係合孔を閉塞するため、内部の液体が流出し難くなる。   According to the second aspect of the present invention, since the movable plate has a disk shape, the movable plate moves in the falling direction and the valve element closes the engagement hole of the movable plate regardless of the direction of the fall. Therefore, it becomes difficult for the liquid inside to flow out.

請求項３の発明によれば、可動板の係合孔が蒸気孔より小さいことにより、容器を転倒した際にも、弁体が可動板の係合孔に確実に入り込むことができ、内部の液体が外部に流出し難くなる。   According to the invention of claim 3, since the engagement hole of the movable plate is smaller than the vapor hole, the valve body can surely enter the engagement hole of the movable plate even when the container is overturned. It becomes difficult for liquid to flow out.

請求項４の発明によれば、可動板が端まで移動しても可動板の係合孔が蒸気孔の面積内に収まることにより、容器を転倒させても可動板の係合孔が常に蒸気孔内に収まり、容器本体内の圧力が高くなっても、直ぐに圧力が抜ける十分な大きさの蒸気孔を確保できる。   According to the invention of claim 4, even if the movable plate moves to the end, the engagement hole of the movable plate is within the area of the steam hole, so that the engagement hole of the movable plate is always steam even if the container is turned over. Even when the pressure in the container body is increased and the pressure in the container body is increased, a sufficiently large steam hole from which pressure can be released immediately can be secured.

請求項５の発明によれば、中栓蒸気孔の出口に可動板と蒸気孔の出口が線接触になるような突起を設けたことにより、容器本体を転倒させた後でも表面張力が働き難くなり、可動板が蒸気孔の出口に張り付き難くなるため、正立させた際に可動板が自重により落下し、蒸気孔の出口に隙間ができ、次に容器本体を転倒させた際も、可動板が転倒方向に移動し、弁体が可動板の係合孔を閉塞して内部の液体が外部に流出し難くなる。
し、弁体が可動板の係合孔を閉塞して内部の液体が外部に流出し難くなる。 According to the invention of claim 5, the surface tension is difficult to work even after the container body is overturned by providing the protrusion at the outlet of the inner plug steam hole so that the movable plate and the outlet of the steam hole are in line contact. Therefore, the movable plate is difficult to stick to the outlet of the steam hole, so the movable plate falls by its own weight when it is erected, a gap is created at the outlet of the steam hole, and it is movable even when the container body is overturned The plate moves in the overturning direction, and the valve body closes the engagement hole of the movable plate, so that the liquid inside does not easily flow out.
Then, the valve body closes the engagement hole of the movable plate, so that the liquid inside does not easily flow out to the outside.

請求項６の発明によれば、可動板が金属製であることにより、耐熱性を確保できると共に、高さを薄くできるので省スペースで転倒時に内部の液体が外部へ流出し難くする構造とすることができる。   According to the invention of claim 6, since the movable plate is made of metal, heat resistance can be ensured and the height can be reduced, so that the internal liquid does not easily flow out to the outside when the vehicle falls over in a space-saving manner. be able to.

Located on the center side. Note that the steam passes between the support rib 64 and the guide rib 66 while the valve body 65 is supported.

前記筒部63の上端面63Ｔ上には、金属製板材からなる可動板67が移動可能に設けられ、この可動板67は円盤状をなしている。また、可動板67の中央には、前記弁体65が係入する係合孔68が穿設され、この係合孔68の直径ｄは前記弁体65の直径Ｄより小さく、直径ｄは直径Ｄの８５〜９５％程度の大きさであり、少なくとも、係合孔68に弁体65が嵌った状態で、可動板67の上面から弁体65の一部が上部に突出して前記係合孔68が塞がれる。また、可動板67の直径は中栓蒸気孔35の直径より大きく、中栓蒸気孔35の直径は係合孔68の直径ｄより大きい。尚、可動板67の外周縁67Ｇと係合孔68とは同心円状に形成されている。   A movable plate 67 made of a metal plate material is movably provided on the upper end surface 63T of the cylindrical portion 63, and the movable plate 67 has a disk shape.

The outer cylinder part 72 is cylindrical, and the inner diameter of the outer cylinder part 72 is It is larger than the diameter D of the movable plate 67. Then, the upper portion of the cylindrical portion 63 is inserted into the lower portion of the outer cylindrical portion 72, and an annular seal member 73 disposed between the inner periphery of the outer cylindrical portion 72 and the outer periphery of the cylindrical portion 63, The cylindrical portion 63 is connected in a watertight manner, whereby the inner plug steam hole 35 and the communication passage 62 are connected in an airtight manner. Further, the movable range of the movable plate 67 is within the outer cylinder portion 72, and the movable range of the vertical direction is the position where the upper surface of the movable plate 67 contacts the protrusion 71 and the movable plate 67. This is the position where the lower surface comes into contact with the upper end surface 63T. Further, the movable plate 67 is sized so that the entire engagement hole 68 always faces the inner plug steam hole 35 in the contact state in the movement range in the inner peripheral surface 72U of the outer cylinder portion 72. Is set.

さらに、図２及び図７に示すように、エアーポット１が転倒し、転倒状態で可動板67が下がると、可動板67の最下部の外周縁67Ｇが外筒部72の内周面72Ｕに当接し、この状態で、可動板67の上面が突起71に線接触すると共に、係合孔68は中栓蒸気孔35の面積の範囲内に位置する。そして、可動板67は、外筒部72の全可動範囲内において、可動板67の上面が突起71の周方向全長に当接し、且つ係合孔68は中栓蒸気孔35の面積の範囲内に位置するように形成されている。   Further, as shown in FIGS. 2 and 7, when the air pot 1 falls and the movable plate 67 falls in the fall state, the lowermost outer peripheral edge 67 </ b> G of the movable plate 67 is brought into contact with the inner peripheral surface 72 </ b> U of the outer cylindrical portion 72. In this state, the upper surface of the movable plate 67 is in line contact with the protrusion 71, and the engagement hole 68 is located within the area of the inner plug steam hole 35. The movable plate 67 has the upper surface of the movable plate 67 in contact with the entire circumferential length of the protrusion 71 within the entire movable range of the outer cylinder portion 72, and the engagement hole 68 is within the area of the inner plug steam hole 35. It is formed so that it may be located in.

図３に示すように、中栓本体12Ｈの外周面12Ｇは円筒状に形成され、その外周面12Ｇにシール部材74が設けられ、また、前記肩部材６の中央には容器本体５の上開口部６Ｂが形成され、この円筒形をなす上開口部６Ｂ内に、前記中栓本体12Ｈの外周面12Ｇが着脱可能に装着され、装着状態で前記シール部材74により水密性が確保されると共に、中栓本体12Ｈの下部が容器本体５内に収納される。   As shown in FIG. 3, the outer peripheral surface 12G of the inner stopper main body 12H is formed in a cylindrical shape, and a sealing member 74 is provided on the outer peripheral surface 12G, and the upper opening of the container main body 5 is provided at the center of the shoulder member 6. A portion 6B is formed, and the outer peripheral surface 12G of the inner plug body 12H is detachably mounted in the cylindrical upper opening 6B, and watertightness is secured by the seal member 74 in the mounted state. The lower part of the inner stopper main body 12H is accommodated in the container main body 5.

そして、内筒２の内圧が規定の圧力よりも上昇するとこのとき弁体42の周囲にはスペースがあり、内筒２内の圧力が高い場合には微動し、内筒２内の圧力を下げる。そして、弁ケース38の他側の側面に蒸気排出部（図示せず）が形成され、この蒸気排出部を介して外気へ沿って排気される。このため、注出時に内筒２の内圧が設定以上の圧力になることはなく、注出流量を一定範囲に維持して内容液を注出することができる。   When the internal pressure of the inner cylinder 2 rises above a specified pressure, there is a space around the valve element 42 at this time, and when the pressure in the inner cylinder 2 is high, the inner cylinder 2 is finely moved to lower the pressure in the inner cylinder 2. . A steam discharge portion (not shown) is formed on the other side surface of the valve case 38, and exhausted along the outside air through the steam discharge portion. For this reason, the internal pressure of the inner cylinder 2 does not become a set pressure or more at the time of pouring, and the content liquid can be poured while maintaining the pouring flow rate within a certain range.

次に、前記構成についてその作用を説明する。開蓋するときは、図示しないロック手段を解除し、蓋体９を上方へ持ち上げ、外すことができる。   Next, the effect | action is demonstrated about the said structure. When opening the lid, the locking means (not shown) can be released, and the lid 9 can be lifted upward and removed.

そして、着脱用取っ手18，18を摘んで中栓12を口部３の上開口部６Ｂから抜き取った後に、ケトル（図示せず）等を用いて湯水を口部３を介して内筒２に収容し、蓋体９を閉める。   Then, after gripping the detachable handles 18 and 18 and pulling out the inner plug 12 from the upper opening 6B of the mouth portion 3, hot water is supplied to the inner cylinder 2 through the mouth portion 3 using a kettle (not shown) or the like. Accommodate and close lid 9.

閉蓋時においては、排気漏洩防止用パッキン32の下端は中栓12の上面と離間しており、中栓蒸気孔35は外気へ通じている。同時に空気漏洩防止用パッキン33の下端は中栓12の上面に密着して中栓空気送入孔36の上端開口の周囲を塞ぐことで、蓋体空気送入孔34と中栓空気送入孔36とを気密に接続できる。   When the lid is closed, the lower end of the exhaust leakage preventing packing 32 is separated from the upper surface of the inner plug 12, and the inner plug vapor hole 35 communicates with the outside air. At the same time, the lower end of the air leakage prevention packing 33 is in close contact with the upper surface of the inner plug 12 and closes the periphery of the upper end opening of the inner plug air inlet hole 36, so that the lid air inlet hole 34 and the inner plug air inlet hole 36 can be connected airtight.

そして、蓋体９を閉じた保温時においては、弁ケース38が中栓蓋12Ｆの上面より離間しているので、内筒２内の蒸気は中栓蒸気孔35、排気漏洩防止用パッキン32、蒸気の蓋側蒸気孔27を介して弁体42の廻りを通って弁ケース38の蒸気排出部より外気へ排気されて、内筒２内は常圧に維持される。   When the cover 9 is kept warm, the valve case 38 is separated from the upper surface of the inner stopper lid 12F, so that the steam in the inner cylinder 2 is the inner stopper steam hole 35, the exhaust leakage preventing packing 32, The steam passes through the valve body 42 through the steam lid side steam hole 27 and is exhausted from the steam discharge portion of the valve case 38 to the outside air, so that the inside of the inner cylinder 2 is maintained at normal pressure.

次に、ロック・ロック解除ボタン51を操作してロック解除とした注出操作体24を押圧すると、パッキン32が中栓蓋12Ｆの上面と密着し、この結果、内筒２は密閉状態となる。また注出操作体24の押圧によって連動部を介してスイッチが閉成して電動式エアーポンプ８が作動して蓋体空気送入孔34から圧縮空気を密閉状態にある内筒２に蓋体空気送入孔34より、空気漏洩防止用パッキン33、中栓空気送入孔36を通して内筒２内に圧送し、内筒２の内圧を上昇させる。この圧送により内筒２の内圧が上昇して収容されている水は揚水パイプ10、注水パイプ11を介して排出される。また、この際内筒２内の圧力が比較的高い場合には重錘体からなる弁体42の上部にはスペースがあり、これによって弁体42が微動し、内筒２内の圧力を適正圧力に下げることができる。   Next, when the locking / unlock button 51 is operated to press the pouring operation body 24 that has been unlocked, the packing 32 comes into close contact with the upper surface of the inner plug lid 12F, and as a result, the inner cylinder 2 is in a sealed state. . Further, the switch is closed via the interlocking portion by the pushing of the pouring operation body 24 and the electric air pump 8 is actuated so that the compressed air is sealed from the lid air inlet hole 34 to the inner cylinder 2 in the sealed state. From the air inlet hole 34, pressure is fed into the inner cylinder 2 through the air leakage prevention packing 33 and the inner plug air inlet hole 36, and the inner pressure of the inner cylinder 2 is increased. The water accommodated by the internal pressure of the inner cylinder 2 rising by this pumping is discharged through the pumping pipe 10 and the water injection pipe 11. At this time, when the pressure in the inner cylinder 2 is relatively high, there is a space above the valve body 42 made of a weight body, which causes the valve body 42 to finely move so that the pressure in the inner cylinder 2 is appropriately adjusted. Can be reduced to pressure.

そして、常時は、図５に示すように、複数の支持リブ64，64・・・の間に弁体65が支持され、中栓蒸気孔35が開口した状態であり、万一、電動式エアーポット１が転倒した場合には、図２及び図７に示すように、支持リブ64の傾斜縁部64Ｋと案内リブ66に沿って弁体65が中栓蒸気孔35側に移動すると共に、弁体65の一部が係合孔68に嵌り、同時に、可動板67が自重で降下して可動板67の外周縁67Ｇが外筒部72の内周面72Ｕに当接すると共に、可動板67の上面が突起71に当接し、この状態で、傾斜縁部64Ｋと案内リブ66により弁体65はその自重により係合孔68に嵌る方向に力を受け、弁体65により係合孔68を塞ぐことができる。このように係合孔68を弁体65により塞ぎ、可動板67が中栓蒸気孔35の突起71に当接することにより、容器本体５内の液体が中内栓蒸気孔35から外部に流出することを抑制することができる。   And normally, as shown in FIG. 5, the valve body 65 is supported between the plurality of support ribs 64, 64... And the inner plug steam hole 35 is opened. When the pot 1 falls, as shown in FIGS. 2 and 7, the valve body 65 moves to the inner plug steam hole 35 side along the inclined edge portion 64K of the support rib 64 and the guide rib 66, and the valve A part of the body 65 fits into the engagement hole 68, and at the same time, the movable plate 67 descends by its own weight so that the outer peripheral edge 67G of the movable plate 67 contacts the inner peripheral surface 72U of the outer cylindrical portion 72. The upper surface is in contact with the protrusion 71. In this state, the valve body 65 receives a force in the direction in which the valve body 65 fits into the engagement hole 68 by its own weight by the inclined edge portion 64K and the guide rib 66, and the valve body 65 closes the engagement hole 68. be able to. Thus, the engagement hole 68 is closed by the valve body 65, and the movable plate 67 contacts the projection 71 of the inner plug steam hole 35, whereby the liquid in the container body 5 flows out from the inner plug steam hole 35 to the outside. This can be suppressed.

また、転倒したエアーポット１を立てれば、図５に示すように、弁体65が降下し、可動板67も自重により上端面63Ｔ上に落下する。この場合、可動板67の上面と突起71とが線接触しているため、面と面との間の表面張力に比べて線接触部分には小さい表面張力しか発生しないから、金属製からなる可動板67の自重により上端面63Ｔに可動板67を復帰させることができる。   Further, when the fallen air pot 1 is set up, as shown in FIG. 5, the valve body 65 is lowered, and the movable plate 67 is also dropped on the upper end surface 63T by its own weight. In this case, since the upper surface of the movable plate 67 and the protrusion 71 are in line contact with each other, only a small surface tension is generated in the line contact portion compared to the surface tension between the surfaces. The movable plate 67 can be returned to the upper end surface 63T by its own weight.

このように本実施例では、請求項１に対応して、液体を収納する上端が開口した容器本体５と、この容器本体５の上開口部６Ｂに着脱可能に装着すると共に容器本体５内と外部とを連通させる蒸気孔35を有した中栓12と、容器本体５の上部に開閉可能に配置した蓋体９とを備えた加圧注出式液体容器において、中栓12に設けられ転倒時に液体が外部に流出し難くする球体の弁体65と、弁体65の上部に設けられ転倒時に転倒方向に移動する可動板67と、弁体65より小さい直径ｄで可動板67に設けられ弁体65が係入する係合孔68とを備えるから、中栓12内部に転倒時に液体が外部に漏れ難くする弁体65と、この弁体65の上部に転倒時に転倒方向に移動し弁体65より小さい直径ｄの係合孔68を有し弁体65が入り込むような可動板67を設けたことにより、容器本体５内の圧力が高くなっても直ぐに圧力が抜ける十分な大きさの中栓蒸気孔35を確保できると共に、弁体65を大きくすることなく省スペース・低コストで転倒時に内部の液体が外部に流入し難くなる構造を提供できる。図９のような従来の円錐形状の弁体102では、弁体102の直径ｄ２を蒸気孔101の直径ｄ１＋5mm程度大きくしなければならないのに対し、本実施例では、球体の弁体65を用いることで係合孔68の直径ｄは弁体65の直径＋1mm程度あればよいため、弁体65をあまり大きくする必要がない。さらに、球体の弁体65の方が円錐形状の弁体102より支持リブ64との接触面積が小さいため、転倒時に滑りやすくなり、中栓蒸気孔35を確実に塞ぐことができる。また、円錐形状の弁体102では転倒時に少しでも傾くと蒸気孔101と弁体102の間に隙間ができ、蒸気孔101が塞がらないため、弁体102が傾かないよう弁体102を支える支持リブの数を多くしなければならなかったが、球体の弁体65では傾きを考慮する必要がないため、リブの数を少なくすることができ、成形時のリブの変形のリスクを低減できる。また、可動板67を別部品にすることで中栓蒸気孔35の変形もしにくくなり、弁体65が中栓蒸気孔35を確実に塞ぐことができる。   Thus, in this embodiment, corresponding to claim 1, the container main body 5 whose upper end for storing the liquid is opened, and the container body 5 is detachably mounted in the upper opening 6B of the container main body 5 and In a pressurized dispensing liquid container having an inner stopper 12 having a vapor hole 35 that communicates with the outside and a lid body 9 that can be opened and closed at the upper part of the container body 5, provided in the inner stopper 12, A spherical valve element 65 that makes it difficult for liquid to flow to the outside, a movable plate 67 that is provided on the upper part of the valve element 65 and moves in the direction of overturning when it falls, and a valve provided on the movable plate 67 with a smaller diameter d than the valve element 65 Since the body 65 is provided with an engagement hole 68 into which the body 65 is engaged, a valve body 65 that makes it difficult for liquid to leak to the outside at the time of the fall inside the inner plug 12 and a valve body that moves in the direction of the fall at the top of the valve body 65 at the time of the fall By providing a movable plate 67 having an engagement hole 68 with a diameter d smaller than 65 and into which the valve body 65 enters, the container body The inside plug steam hole 35 large enough to release pressure immediately even when the pressure inside the tank 5 rises can be secured, and the internal liquid can be transferred to the outside at the time of a fall without saving the valve body 65 and saving space and cost. It is possible to provide a structure that is difficult to flow in. In the conventional conical valve body 102 as shown in FIG. 9, the diameter d2 of the valve body 102 has to be increased by about the diameter d1 + 5 mm of the steam hole 101, whereas in this embodiment, a spherical valve body 65 is used. Thus, since the diameter d of the engagement hole 68 may be about the diameter of the valve body 65 + 1 mm, the valve body 65 does not need to be made too large. Further, since the spherical valve element 65 has a smaller contact area with the support rib 64 than the conical valve element 102, the spherical valve element 65 becomes slippery during a fall, and the inner plug steam hole 35 can be reliably closed. The conical valve body 102 supports the valve body 102 so that the valve body 102 does not tilt because a gap is formed between the steam hole 101 and the valve body 102 when the valve body 102 is tilted even if it falls down. Although the number of ribs had to be increased, the spherical valve body 65 does not need to consider the inclination, so the number of ribs can be reduced, and the risk of rib deformation during molding can be reduced. Further, by making the movable plate 67 a separate part, the inner plug steam hole 35 is hardly deformed, and the valve body 65 can reliably block the inner plug steam hole 35.

また、このように本実施例では、請求項２に対応して、可動板67が円盤状となっているから、どの方向に転倒しても、転倒方向に可動板67が移動して弁体65が可動板67の係合孔68を閉塞するため、内部の液体が流出し難くなる。   In this way, in this embodiment, since the movable plate 67 has a disk shape corresponding to the second aspect, the movable plate 67 moves in the overturning direction regardless of the direction of the overturning and the valve body. Since 65 closes the engagement hole 68 of the movable plate 67, the liquid inside does not easily flow out.

また、このように本実施例では、請求項３に対応して、可動板67の係合孔68が蒸気孔35より小さいから、容器を転倒した際にも、弁体65が可動板67の係合孔68に確実に入り込むことができ、内部の液体が外部に流出し難くなる。   As described above, in this embodiment, the engagement hole 68 of the movable plate 67 is smaller than the steam hole 35 in correspondence with the third aspect. It is possible to surely enter the engagement hole 68, and the liquid inside does not easily flow out to the outside.

また、このように本実施例では、請求項４に対応して、可動板67が端まで移動しても可動板67の係合孔68が蒸気孔35の面積内に収まるから、容器を転倒させても可動板37の係合孔68が常に蒸気孔35内に収まり、容器本体５内の圧力が高くなっても、直ぐに圧力が抜ける十分な大きさの蒸気孔35を確保できる。   In this way, in this embodiment, corresponding to claim 4, even if the movable plate 67 moves to the end, the engagement hole 68 of the movable plate 67 is within the area of the steam hole 35. Even if it is made, the engagement hole 68 of the movable plate 37 always fits in the steam hole 35, and even if the pressure in the container body 5 increases, it is possible to secure a sufficiently large steam hole 35 from which the pressure is released immediately.

また、このように本実施例では、請求項５に対応して、蒸気孔35の周囲に可動板67と該蒸気孔35の周囲が線接触となるような突起71を設けたから、中栓蒸気孔35の出口に可動板67と蒸気孔35の出口が線接触になるような突起71を設けたことにより、容器本体５を転倒させた後に表面張力が働き難くなり、可動板67が蒸気孔35の出口に張り付き難くなるため、正立させた際に可動板67が自重により上端面63Tに落下し、と蒸気孔35の出口に隙間ができ、次に容器本体５を転倒させた際も、可動板67が転倒方向に移動し、弁体65が可動板67の係合孔68を閉塞して内部の液体が外部に流出し難くなる。   Further, in this embodiment, in correspondence with claim 5, since the movable plate 67 and the projection 71 which makes the periphery of the steam hole 35 are in line contact are provided around the steam hole 35, the inside plug steam By providing a protrusion 71 at the outlet of the hole 35 so that the movable plate 67 and the outlet of the steam hole 35 are in line contact, the surface tension becomes difficult to work after the container body 5 is overturned. Since it becomes difficult to stick to the outlet of 35, the movable plate 67 falls to the upper end surface 63T due to its own weight when it is erected, and a gap is formed at the outlet of the steam hole 35, and then the container body 5 is turned over. The movable plate 67 moves in the overturning direction, and the valve body 65 closes the engagement hole 68 of the movable plate 67, so that the liquid inside does not easily flow out.

また、このように本実施例では、請求項６に対応して、可動板67が金属製であるから、耐熱性を確保できると共に、高さを薄くできるので省スペースで転倒時に内部の液体が外部へ流出し難くする構造とすることができる。   Further, in this embodiment, corresponding to claim 6, since the movable plate 67 is made of metal, heat resistance can be ensured and the height can be reduced, so that the internal liquid can be saved at the time of falling in a space-saving manner. A structure that makes it difficult to flow out can be provided.
