前記カバー25は、栓本体11の筒体13の上開口部42を覆うものであり、その筒体13に嵌合して上開口部42に着脱自在に設けられる。前記カバー25の中央には、他側である肩部材７側が開口する切欠き状の開口部25Ａを設け、この開口部25Ａに前記操作レバー24が配置され、この操作レバー24の一側が枢着部43によりカバー25に傾動可能に枢着され、また、操作レバー24の操作部44がカバー25の他側から外部に突出し、前記肩部材７の上方に位置している。また、操作レバー24の下面には、操作レバー24が回動時前記弁棒23の上端が当接する位置に、凸部24Ａを設け、この凸部24Ａの下面は平坦面に形成されている。   The cover 25 covers the upper opening 42 of the cylindrical body 13 of the plug body 11, and is fitted to the cylindrical body 13 so as to be detachable from the upper opening 42. At the center of the cover 25 is provided a notch-shaped opening 25A that opens on the other side of the shoulder member 7, and the operation lever 24 is disposed in the opening 25A, and one side of the operation lever 24 is pivotally attached. The operation lever 44 is pivotally attached to the cover 25 by the portion 43, and the operation portion 44 of the operation lever 24 projects outside from the other side of the cover 25 and is located above the shoulder member 7. Further, a convex portion 24A is provided on the lower surface of the operating lever 24 at a position where the upper end of the valve rod 23 abuts when the operating lever 24 rotates, and the lower surface of the convex portion 24A is formed as a flat surface.

前記筒体13の一側上部には、突片部48を設け、この突片部48に第１係合部たる横孔部49を設け、この横孔部49に係合する第１被係合部たる突起部50を前記カバー25の一側に設け、前記突起部50は他側向きに突設され、横孔部49に突起部50が段発的に係止する。   A protruding piece portion 48 is provided on one side upper portion of the cylindrical body 13, and a horizontal hole portion 49 that is a first engaging portion is provided in the protruding piece portion 48, and a first engaged member that engages with the horizontal hole portion 49. A projecting portion 50 as a joint portion is provided on one side of the cover 25, the projecting portion 50 is projected toward the other side, and the projecting portion 50 is locked in a stepped manner in the lateral hole portion 49.

一方、筒体13の他側上部には、弾性片52を上方に向かって突出し、この弾性片52は下端のみが筒体13に連結され、上端が自由端であり、その弾性片52の外面に第２係合部たる係合爪部53が形成されている。   On the other hand, an elastic piece 52 protrudes upward on the other side upper part of the cylinder 13, and the elastic piece 52 is connected to the cylinder 13 only at the lower end, and the upper end is a free end, and the outer surface of the elastic piece 52 An engagement claw portion 53 as a second engagement portion is formed in the first and second engagement portions.

前記カバー25の他側下部には、第２被係合部たる横板部54の横板上面54Ｕが一体に設けられている。   On the other lower side of the cover 25, a horizontal plate upper surface 54U of the horizontal plate portion 54 as a second engaged portion is integrally provided.

また、前記操作レバー24の下面には突出片58が下方に突設され、この突出片58は一側に縦縁部59を有し、他側は傾斜した縁となり、側面視で略三角形状をなし、操作レバー24の操作時に前記弾性片52に係合する位置に前記縦縁部59が配置され、この縦縁部59の下部には、上から下に向って他側に傾斜した当接縁部59Ａが設けられている。   In addition, a projecting piece 58 projects downward from the lower surface of the operation lever 24. The projecting piece 58 has a vertical edge 59 on one side and an inclined edge on the other side, and is substantially triangular in side view. The vertical edge portion 59 is disposed at a position that engages with the elastic piece 52 when the operation lever 24 is operated, and a lower portion of the vertical edge portion 59 is inclined to the other side from the top to the bottom. A contact portion 59A is provided.

そして、操作レバー24を下方に回動すると、当接縁部59Ａが前記中央傾斜面53Ａに当接し、弾性片52をその解除方向に押して横板上面54Ｕとの係合を解除する。   When the operation lever 24 is rotated downward, the contact edge portion 59A contacts the central inclined surface 53A, and the elastic piece 52 is pushed in the releasing direction to release the engagement with the horizontal plate upper surface 54U.

また、容器本体２を栓体３に装着した状態で、突出片58とレバー24の操作部44と肩部材７とは、操作部44を押し下げると、操作部44の下部が、回動規制部たる肩部材７の上面に当接し、このように操作レバー24の回動範囲を規制することにより、弾性片52に突出片58が当接することがない。   Further, when the container body 2 is mounted on the stopper 3, when the operation portion 44 of the projecting piece 58, the lever 24, and the shoulder member 7 are pushed down, the lower portion of the operation portion 44 becomes the rotation restricting portion. By contacting the upper surface of the shoulder member 7 and thus restricting the rotation range of the operation lever 24, the projecting piece 58 does not contact the elastic piece 52.

次に前記構成についてその作用を説明する。栓体３の組み立てにあっては、まず、一側において、横孔部49に突起部50を挿入して係合する。この係合箇所を中心として、カバー25の他側を押し下げると、横板部54が係合爪部53の外面に当接し、弾性片52が内側に弾性変形し、係合爪部53に横板部54が係止し、栓本体11にカバー25が固定される。   Next, the operation of the above configuration will be described. In assembling the plug body 3, first, on one side, the protruding portion 50 is inserted into and engaged with the lateral hole portion 49. When the other side of the cover 25 is pushed down with the engaging portion as the center, the horizontal plate portion 54 comes into contact with the outer surface of the engaging claw portion 53, the elastic piece 52 elastically deforms inward, and the engaging claw portion 53 The plate portion 54 is locked, and the cover 25 is fixed to the plug body 11.

また、別の方法として、突起部50の下部に斜面を持たせると、突片部48も弾性があるため、カバー25を栓本体11に上方から押えるだけで、栓本体11にカバー25を固定することができる。   As another method, if the lower surface of the projection 50 has a slope, the protrusion 48 also has elasticity, so the cover 25 can be fixed to the plug body 11 simply by pressing the cover 25 against the plug body 11 from above. can do.

そして、容器本体２に栓体３を螺合して装着した状態で、操作レバー24の操作部44を押し下げると、操作レバー24は、一端の枢着部43を支点に回動する。操作レバー24の回動に伴って、操作レバー24の凸部24Ａが弁棒23の上端を下方に押し下げ、弁棒23と弁体21とが弾性部材22の付勢力に抗して、一体となって下方に移動する。これに伴って、止水パッキン27が筒体13の下端部13Ｋを離れ、流液経路８が開放され、飲料容器１を注ぎ部７Ｂ方向へ傾けると、内容液が流液経路８，注ぎ部７Ｂを通って注出される。また、操作レバー24は、操作部44の下部が、回動規制部たる肩部材７の上面に当接することによって回動が規制され、横板部54は弾性片52に係合した状態に保持され、この位置が回動規制位置である。   When the operation part 44 of the operation lever 24 is pushed down with the stopper 3 screwed onto the container body 2, the operation lever 24 rotates about the pivot part 43 at one end. As the operation lever 24 rotates, the convex portion 24A of the operation lever 24 pushes down the upper end of the valve rod 23, and the valve rod 23 and the valve body 21 are united against the urging force of the elastic member 22. And move down. Along with this, the water-stopping packing 27 leaves the lower end portion 13K of the cylindrical body 13, the flow path 8 is opened, and the beverage container 1 is tilted in the direction of the pouring part 7B. It is poured out through 7B. Further, the operation lever 24 is restricted from rotating by the lower portion of the operation portion 44 coming into contact with the upper surface of the shoulder member 7 serving as the rotation restricting portion, and the horizontal plate portion 54 is held in a state of being engaged with the elastic piece 52. This position is the rotation restricting position.

一方、容器本体２内に、熱湯や熱い飲料物が注入されていると、水蒸気によって容器本体２内が昇圧している場合がある。この場合、弁棒23はストロークＳだけ降下可能であり、操作レバー24を回動させると、弁体21は容器内の圧力によって止水パッキン27が筒体13の下端部13Ｋに押し付けられた状態のまま、弁棒23の下降によって面積の小さな減圧パッキン41が弁体21の下面から離れ、容器本体２内の圧力が逃げる。この場合、受筒部62と軸部29の下部29Ｓと間の隙間、挿通溝61及び切欠き溝63により、容器本体２内の圧力をスムーズに逃がすことができる。そして、容器本体２内の圧力が開放されることにより、弁体21の上方への加圧保持力が無くなり、重力により下方に下がると共に、更に操作レバー24を押し込むと前記係止溝66がなくなり係止溝66の上縁に係合突部65が当接して弁棒23が弁体21を押し下げ、より大きく弁体21が開状態となる。   On the other hand, when hot water or a hot beverage is injected into the container body 2, the inside of the container body 2 may be pressurized by steam. In this case, the valve stem 23 can be lowered by the stroke S, and when the operation lever 24 is rotated, the valve body 21 is pressed against the lower end portion 13K of the cylinder 13 by the pressure in the container. The pressure reducing packing 41 having a small area is separated from the lower surface of the valve body 21 by the lowering of the valve stem 23, and the pressure in the container body 2 is released. In this case, the pressure in the container body 2 can be released smoothly by the gap between the receiving tube portion 62 and the lower portion 29S of the shaft portion 29, the insertion groove 61 and the notch groove 63. When the pressure in the container body 2 is released, the pressure holding force upward of the valve body 21 is lost, the pressure body is lowered downward due to gravity, and when the operation lever 24 is further pushed, the locking groove 66 disappears. The engagement protrusion 65 comes into contact with the upper edge of the locking groove 66, and the valve rod 23 pushes down the valve body 21, so that the valve body 21 is largely opened.

また、容器本体２内に熱湯や熱い飲料物が注入され、吐出により一度弁体21を開放し、容器本体２内の内圧を開放したあと放置した場合など、容器本体２内が減圧状態になっている場合がある。この場合、減圧力が弾性部材22の弾性復元力より強くなると、自動的に弁棒23が下降し、減圧パッキン41が弁体21の下面から離れ、容器本体２内の圧力が大気と同圧に開放される。容器本体２内の圧力と大気が同圧となると再び弾性部材22の力により挿通孔61は閉状態となる。   In addition, when the hot water or hot beverage is injected into the container body 2 and the valve body 21 is once opened by discharge and the internal pressure in the container body 2 is released, the container body 2 is in a decompressed state. There may be. In this case, when the decompression force becomes stronger than the elastic restoring force of the elastic member 22, the valve stem 23 is automatically lowered, the decompression packing 41 is separated from the lower surface of the valve body 21, and the pressure in the container body 2 is the same as the atmospheric pressure. Released. When the pressure in the container main body 2 and the atmosphere become the same pressure, the insertion hole 61 is closed again by the force of the elastic member 22.

また、栓体３を容器本体２から外し、操作レバー24の操作部44を前記回動規制位置よりも更に押し下げると、弾性片52の外面に、突出片58の当接縁部59Ａが当接し、ここから、操作レバー24を下げると、突出片58により弾性片52が内側に弾性変形し、係合爪部53が横板上面54Ｕから外れる。   Further, when the stopper 3 is detached from the container body 2 and the operation portion 44 of the operation lever 24 is further pushed down from the rotation restricting position, the contact edge portion 59A of the protruding piece 58 comes into contact with the outer surface of the elastic piece 52. From this point, when the operation lever 24 is lowered, the elastic piece 52 is elastically deformed inward by the protruding piece 58, and the engaging claw portion 53 is detached from the upper surface 54U of the horizontal plate.

このようにして係合爪部53が横板上面54Ｕから外れると、弾性部材22により弁棒23が操作レバー24を上方に押し、操作レバー24が上方に回動し、カバー25の他側が栓本体11から外れる。   Thus, when the engaging claw 53 is disengaged from the upper surface 54U of the horizontal plate, the valve rod 23 pushes the operation lever 24 upward by the elastic member 22, the operation lever 24 rotates upward, and the other side of the cover 25 is plugged. Detach from the body 11.

栓本体11からカバー25を外したら、弁棒23の上部から弁体カバー37を外し、弁棒23，弾性部材22，弁体21を栓本体11から取り外すことができる状態となり、栓本体11の流液経路８や弁機構12を別々に洗浄することができる。   When the cover 25 is removed from the plug body 11, the valve body cover 37 is removed from the upper part of the valve rod 23, and the valve rod 23, the elastic member 22, and the valve body 21 can be removed from the plug body 11. The flow path 8 and the valve mechanism 12 can be cleaned separately.

この場合、弁体21に対して弁棒23を回すと、弾性片64が径方向外側に弾性変形して係合突部65が突条67を通過し、係合突部65を上下方向の挿通溝31に合わせることにより、弁体21から弁棒23を引き抜き、弁体21と弁棒23とを分離して洗浄することができる。   In this case, when the valve stem 23 is rotated with respect to the valve body 21, the elastic piece 64 is elastically deformed radially outward, the engaging protrusion 65 passes through the protrusion 67, and the engaging protrusion 65 is moved in the vertical direction. By matching with the insertion groove 31, the valve stem 23 can be pulled out from the valve body 21, and the valve body 21 and the valve stem 23 can be separated and cleaned.

洗浄後の弁機構12を栓本体11に装着する際には、逆に、弁棒23の軸部29を弁体21に挿入し、弁体21に対して弁棒23を回し、係合突部65が弾性変形して突条67を越え、係合突部65が係止溝66の終端66Ｔに回り止め状態で係止し、これにより弁体21に弁棒23が組み込まれ、さらに、軸部29を挿通孔33とガイド筒34に挿通し、このガイド筒34に弾性部材22を外装し、弾性部材22の上に弁体カバー37を被せ、弁体カバー37に軸部29の上部29Ｕに係止する。   When attaching the cleaned valve mechanism 12 to the plug body 11, conversely, the shaft part 29 of the valve stem 23 is inserted into the valve body 21, and the valve stem 23 is turned with respect to the valve body 21 to engage the protrusion. The portion 65 is elastically deformed and exceeds the protrusion 67, and the engaging protrusion 65 is locked to the terminal end 66T of the locking groove 66 in a non-rotating state, whereby the valve stem 23 is incorporated in the valve body 21, The shaft portion 29 is inserted into the insertion hole 33 and the guide tube 34, the elastic member 22 is sheathed on the guide tube 34, the valve body cover 37 is covered on the elastic member 22, and the upper portion of the shaft portion 29 is covered with the valve body cover 37. Lock to 29U.

以上のように、弁体21と弁棒23を個々の別部材にし、弁棒23に弁体21の上部への流液経路８の入口15を閉じる弁体21を設けることで、弁棒23の方が弁体21より径が小さくなることから、湯などにより容器本体２内の内圧が高くなっているときでも、先に弁棒23側の弁体である円盤部28を押し下げ、内圧を開放できるため、内圧により弁体21が押下げ不能になることを防ぎ、確実に内溶液を吐出させることができる。このとき弁棒23には挿通溝31があり、弁体21の挿通孔61及び受筒部62との間に隙間を作ることで、確実に内圧を排気することができる。このようにして内圧を解放すると、弁体21の上方への加圧保持力が無くなり、重力により下方に下がり、弁体21が開状態となる。   As described above, the valve body 21 and the valve stem 23 are formed as separate members, and the valve stem 23 is provided on the valve stem 23 to close the inlet 15 of the fluid flow path 8 to the upper portion of the valve body 21. Since the diameter of the valve body 21 is smaller than that of the valve body 21, even when the internal pressure in the container body 2 is high due to hot water or the like, the disk portion 28, which is the valve body on the valve stem 23 side, is first pushed down to reduce the internal pressure Since it can be opened, it is possible to prevent the valve body 21 from being pushed down by the internal pressure, and to reliably discharge the internal solution. At this time, the valve rod 23 has an insertion groove 31, and the internal pressure can be reliably exhausted by creating a gap between the insertion hole 61 of the valve body 21 and the receiving cylinder portion 62. When the internal pressure is released in this way, the pressure holding force upward of the valve body 21 is lost, and the valve body 21 is opened by gravity and is opened.

一方、容器本体２内が減圧状態になった場合、その減圧力が弾性部材22の弾性復元力より強くなると、自動的に弁棒23が下降し、減圧パッキン41が弁体21の下面から離れ、容器本体２内の圧力が大気と同圧に開放される。容器本体２内の圧力と大気が同圧となると再び弾性部材22の力により挿通孔61は閉状態となる。   On the other hand, when the inside of the container body 2 is in a decompressed state, when the decompression force becomes stronger than the elastic restoring force of the elastic member 22, the valve stem 23 is automatically lowered and the decompression packing 41 is separated from the lower surface of the valve body 21. The pressure in the container body 2 is released to the same pressure as the atmosphere. When the pressure in the container main body 2 and the atmosphere become the same pressure, the insertion hole 61 is closed again by the force of the elastic member 22.

さらに、中仕切り部14の下方に配置する従来の弾性部材104を無くすことで、例えば、従来、流液経路８に設けていた金属製のコイルスプリングが不要となり、衛生的で、部品点数を減らしてコストダウンを図ることができる。   Further, by eliminating the conventional elastic member 104 disposed below the partition 14, for example, a metal coil spring conventionally provided in the flowing liquid path 8 becomes unnecessary, which is hygienic and reduces the number of parts. Cost reduction.

このように本実施例では、請求項１に対応して、容器本体２の開口部２Ａに着脱可能に装着される栓本体11の内側に、容器本体２の内部に開口する入口15から外部に開口する出口16に至る流液経路８を形成し、流液経路８の入口15を閉じる弁体21を設け、栓本体11の上端に該栓本体11の上開口部42を閉じるカバー25を設け、カバー25に弁体21を開閉する開閉装置たる操作レバー24を設けた飲料容器の栓体において、弁体21には閉方向に付勢する弾性部材22が取り付けられ、この弾性部材22の抜け防止に弁体カバー37が装着され、弁体21と弁棒23は個々の構成に別れ、該弁棒23には弁体21上部への流液経路８の入口15を閉じる弁体21を設け、弁体21には係合突部65を設け、弁棒23には、弁体21の係合突部65が挿通する挿通溝31及び弁体21を回転方向に回すことで弁体21の係合突部65が乗り越え係合する被係合突部たる突条67を設けたから、弾性部材104や係止板103も無くすことができ、部品点数を減らし、コストダウンにつながるだけでなく、弁棒23と弁体21を回転方向に回すことで分解でき、さらに、例えば弾性部材104が金属の場合などには流液経路に晒されることがない。   Thus, in this embodiment, corresponding to claim 1, the inside of the stopper body 11 that is detachably attached to the opening 2 </ b> A of the container body 2, and the outside from the inlet 15 that opens inside the container body 2. A fluid flow path 8 leading to the outlet 16 that opens is provided, a valve body 21 that closes the inlet 15 of the fluid flow path 8 is provided, and a cover 25 that closes the upper opening 42 of the plug body 11 is provided at the upper end of the plug body 11. In the stopper of the beverage container provided with the operation lever 24 as an opening / closing device for opening and closing the valve body 21 on the cover 25, the valve body 21 is attached with an elastic member 22 that urges in the closing direction. A valve body cover 37 is attached to prevent the valve body 21 and the valve stem 23 from being separated into individual structures. The valve body 21 is provided with an engagement protrusion 65, and the valve rod 23 is inserted into the insertion groove 31 through which the engagement protrusion 65 of the valve body 21 is inserted, and the valve body 21 is rotated in the rotation direction. Since the protrusion 67, which is the engaged protrusion that the 21 engaging protrusions 65 get over and engage with, is provided, the elastic member 104 and the locking plate 103 can be eliminated, reducing the number of parts and reducing the cost. The valve rod 23 and the valve body 21 can be disassembled by rotating them in the rotational direction. Further, for example, when the elastic member 104 is made of metal, it is not exposed to the fluid flow path.

また、このように本実施例では、請求項２に対応して、弁体21と弁棒23が係合した状態で、弁棒23が自由に上下動できるストロークＳを設けたから、弁体21と弁棒23の嵌合状態で弁体21にストローク幅を持たせることで、熱い湯などにより容器本体２内の内圧が上昇した場合に、操作レバー24を押したとき、弁体21より先に径の小さい弁棒23が先に押されることで、内圧を速やかに開放することができる。このとき弁棒23に設けられた弁体21の挿通溝31が空気の通気溝として作用し、内圧を逃がすことができる。   In this way, in this embodiment, in correspondence with claim 2, since the valve body 21 and the valve stem 23 are engaged with each other, a stroke S is provided so that the valve stem 23 can freely move up and down. When the internal pressure in the container body 2 rises due to hot water, etc., when the operating lever 24 is pushed, the valve body 21 is wider than the valve body 21 by giving the valve body 21 a stroke width with the valve rod 23 fitted. When the valve rod 23 having a small diameter is pushed first, the internal pressure can be quickly released. At this time, the insertion groove 31 of the valve body 21 provided in the valve stem 23 acts as an air ventilation groove, and the internal pressure can be released.
