Description

本考案は、着脱可能な飲み口を備えた飲料容器の栓体に関する。   The present invention relates to a stopper of a beverage container having a detachable drinking mouth.

マグボトル等の携帯用の飲料容器では、上面が開口された金属製の容器本体の上部に飲み口を有する栓体が装着される。容器本体に取り付けられる栓本体に飲み口は上下方向に着脱可能に設けられ、飲み口を栓本体から下方へ外すと、飲み口を容易に洗浄することができる。特許文献1には、栓本体に対して飲み口が回動することにより、飲み口を栓本体に係止した状態と係止が解除された状態になることが記載されている。   In a portable beverage container such as a mug bottle, a stopper having a drinking mouth is attached to an upper part of a metal container body having an upper surface opened. A drinking mouth is detachably provided in the stopper body attached to the container body, and the drinking mouth can be easily washed by removing the drinking mouth downward from the stopper body. Patent Document 1 describes that the drinking mouth rotates with respect to the stopper main body, whereby the drinking mouth is locked to the stopper main body and the locking state is released.

特開2015−98352号公報JP2015-98352A

飲み口を栓本体に着脱するとき、飲み口を栓本体に対して出し入れする操作の他に飲み口を回動させる操作が必要となる。回動させるために、飲み口の下部を持たなければならないが、飲み口と栓本体との間の隙間が小さいと、飲み口を掴みにくく、しかも回動させにくい。そのため、飲み口を着脱するのに手間取るおそれがある。   When attaching and detaching the drinking mouth to and from the stopper main body, an operation for rotating the drinking outlet is required in addition to the operation for inserting and removing the drinking mouth with respect to the stopper main body. In order to rotate, it is necessary to have a lower part of the drinking mouth, but if the gap between the drinking mouth and the stopper body is small, it is difficult to grasp the drinking mouth and it is difficult to rotate. Therefore, it may take time to attach and detach the drinking mouth.

本考案は、上記に鑑み、手間のかかる操作を行わなくても、飲み口を容易に着脱できる飲料容器の栓体の提供を目的とする。   In view of the above, an object of the present invention is to provide a beverage container stopper that can be easily attached and detached without a time-consuming operation.

本考案は、容器本体に着脱可能に取り付けられる飲料容器の栓体であって、容器本体の開口縁部に被着される筒状の栓本体と、栓本体の内壁に着脱可能に取り付けられる飲み口とを備え、飲み口を栓本体の内壁に対して着脱可能に係止する左右両側の規制体が、飲み口の外周面の凹部に出退可能に収納され、各規制体を飲み口の外周面から突出する方向に付勢する弾性片が設けられる。飲み口の栓本体への装着時に、飲み口を栓本体に対して下側から挿入することにより、規制体が栓本体に当接して、弾性片の付勢力に抗して凹部内に退き、栓本体の上下方向の所定位置で飲み口は弾性片の付勢力により栓本体の内壁に係止され、飲み口の栓本体からの取り外し時に、左右両側の規制体を弾性片の付勢力に抗して半径方向に近付けることにより、規制体が栓本体の内壁から離れ、飲み口を栓本体に対して下方向に移動させることにより、飲み口が栓本体から離脱される。   The present invention is a beverage container plug that is detachably attached to a container body, a cylindrical plug body that is attached to the opening edge of the container body, and a drink that is detachably attached to the inner wall of the plug body. And restricting bodies on both the left and right sides that are detachably locked to the inner wall of the stopper main body are removably accommodated in the recesses on the outer peripheral surface of the drinking mouth. An elastic piece that biases in a direction protruding from the outer peripheral surface is provided. When the spout is attached to the main body of the spout, by inserting the spout from the lower side with respect to the main body of the spout, the regulating body comes into contact with the main body of the spout and retracts into the recess against the urging force of the elastic piece, The drinking mouth is locked to the inner wall of the stopper body by the biasing force of the elastic piece at a predetermined position in the vertical direction of the stopper body, and when the drinking mouth is removed from the stopper body, the right and left restricting bodies resist the biasing force of the elastic piece. By moving closer to the radial direction, the regulating body is separated from the inner wall of the plug main body, and the drinking mouth is detached from the plug main body by moving the drinking mouth downward with respect to the plug main body.

このように、弾性片の付勢力に抗して2つの規制体を左右両側から挟み込むように半径方向に近付けることにより、規制体を栓本体の内壁から離脱させ、飲み口を下方向に移動させることにより飲み口は栓本体から離脱可能とされる。これにより、飲み口を栓本体から容易に取り外すことができる。   In this way, the restricting body is separated from the inner wall of the plug body by moving the two restricting bodies in the radial direction so as to sandwich the two restricting bodies from the left and right sides against the urging force of the elastic piece, and the drinking mouth is moved downward. Thus, the drinking mouth can be detached from the stopper body. Thereby, a drinking mouth can be easily removed from a stopper main body.

栓本体は、容器本体の外筒に被着される外壁と、その上端縁部を内側に折り返して容器本体の内側に被着される内壁とを備え、内壁には2つの規制体を上下方向に案内する縦溝が形成され、規制体は栓本体の上端縁部に係脱可能に係止されるようになっている。そのため、飲み口の装着時には、規制体と縦溝とを合わせるだけで飲み口を栓本体の所定位置に容易に案内することができる。   The stopper body includes an outer wall attached to the outer cylinder of the container body, and an inner wall attached to the inner side of the container body with the upper edge thereof folded inward. A regulating groove is formed so as to be detachably locked to the upper end edge of the plug body. Therefore, when the drinking mouth is mounted, the drinking mouth can be easily guided to a predetermined position of the stopper body simply by aligning the regulating body and the longitudinal groove.

飲み口の外周面において、上下方向の中間部に半径方向外側に突出する外周フランジが形成され、この外周フランジが栓本体の内壁の下端に当接して飲み口の上方への移動を阻止する。これにより、飲み口の上方への移動は外周フランジで規制され、飲み口の下方への移動は規制体により制限され、飲み口が栓本体に確実に保持される。   On the outer peripheral surface of the drinking mouth, an outer peripheral flange that protrudes radially outward is formed at an intermediate portion in the vertical direction, and this outer peripheral flange abuts the lower end of the inner wall of the stopper main body to prevent the upward movement of the drinking mouth. Thereby, the upward movement of the drinking mouth is restricted by the outer peripheral flange, the downward movement of the drinking mouth is restricted by the regulating body, and the drinking mouth is securely held by the stopper body.

外周フランジは、飲み口の外周面に形成された凹部以外の部分に形成され、凹部に収容される規制体の下部には、栓本体の内壁の下端縁に当接して飲み口の上方向への移動を阻止する阻止部が形成されている。これにより、飲み口の外周フランジのみならず、規制体の下部も栓本体の内壁の下端縁に当接するので、飲み口を確実に栓本体に係止することができる。   The outer peripheral flange is formed in a portion other than the concave portion formed on the outer peripheral surface of the drinking mouth, and the lower part of the regulating body accommodated in the concave portion is in contact with the lower end edge of the inner wall of the stopper main body and moves upward in the drinking mouth. A blocking portion is formed to block the movement. As a result, not only the outer peripheral flange of the drinking mouth but also the lower part of the restricting body comes into contact with the lower end edge of the inner wall of the stopper body, so that the drinking mouth can be reliably locked to the stopper body.

各規制体は、栓本体の上端縁部に係合して飲み口の下方への移動を阻止するフックを有し、該フックは、上部側が外側に膨らんだ頭部と、中間の胴部と、胴部の下方に位置する脚部とを備え、頭部と胴部との境界部には、栓本体の上端縁部に係合する段差が形成され、頭部の中央に飲み口を栓本体から取り外すときに操作する摘み部が設けられている。これにより、段差が栓本体の内壁に係止され、胴部が内壁に接触する。規制体を栓本体の内壁に密接させることができる。   Each restricting body has a hook that engages with the upper edge of the stopper main body to prevent the downward movement of the drinking mouth, and the hook includes a head that bulges outward on the upper side, an intermediate body, And a leg portion located below the torso, and at the boundary between the head and the torso, a step is formed that engages with the upper edge of the plug body, and the spout is plugged in the center of the head. A knob portion is provided for operation when removing from the main body. Thereby, a level | step difference is latched by the inner wall of a stopper main body, and a trunk | drum contacts an inner wall. The regulating body can be brought into close contact with the inner wall of the plug body.

摘み部が栓本体の内壁の縦溝に嵌合して上下方向に案内され、摘み部の両側には縦溝両側の内壁に沿って案内されるガイド部が形成され、ガイド部は、栓本体の内壁の下端から上方に案内しやすいように、上方に向かうほど栓本体の外壁側に向かう湾曲状の傾斜面が形成されている。したがって、ガイド部により規制体を栓本体の内壁に上下方向に移動するのを案内することができ、飲み口の装着作業を容易に行うことができる。   The knob is fitted in the vertical groove on the inner wall of the plug body and guided in the vertical direction. Guide parts are formed on both sides of the knob along the inner walls on both sides of the vertical groove. A curved inclined surface is formed toward the outer wall side of the plug body as it goes upward so that it can be easily guided upward from the lower end of the inner wall. Therefore, the guide part can guide the movement of the restricting body to the inner wall of the stopper main body in the vertical direction, and the attaching operation of the drinking mouth can be easily performed.

フックの下端部が凹部に支軸回りに揺動可能に支持され、脚部の後側にフックを突出方向に付勢する弾性片が一体的に設けられている。これにより、別体の弾性片を設ける必要がなく、簡単な構成により、規制体を飲み口の外周面から突出する方向に付勢することができる。   The lower end portion of the hook is supported by the recess so as to be swingable around the support shaft, and an elastic piece for biasing the hook in the protruding direction is integrally provided on the rear side of the leg portion. Thereby, it is not necessary to provide a separate elastic piece, and the regulating body can be urged in a direction protruding from the outer peripheral surface of the drinking mouth with a simple configuration.

本考案によると、規制体だけで飲み口を栓本体に係止することができ、規制体に対する操作を行うことにより飲み口を栓本体から外すことが可能となる。したがって、簡単な構造で飲み口を着脱することができる飲料容器を提供することができる。   According to the present invention, the drinking mouth can be locked to the stopper body only by the regulating body, and the drinking mouth can be removed from the stopper body by performing an operation on the regulating body. Therefore, the drink container which can attach or detach a drinking mouth with a simple structure can be provided.

And a lid 7 that opens and closes the drinking mouth 6. As shown in FIG. 7, the plug body 5 has an outer wall 5a formed in a cylindrical shape, and an inner wall 5c formed in an inverted U-shape from the upper end edge 5b of the outer wall 5a. The inner wall 5c is formed lower than the outer wall 5a and has a function of engaging and holding the drinking mouth 6 with the stopper body 5 as will be described later.

栓本体5の外壁5aの内側には雌ねじが形成され、この雌ねじが容器本体1の外筒の雄ねじに螺着することで、栓本体5が容器本体1の開口端部に装着される。栓本体5の外壁5aと内壁5cとの間に形成された隙間に、容器本体1の開口端部が挿入される。栓本体5の内壁5cの内側には飲み口6が配設される。   A female thread is formed inside the outer wall 5 a of the stopper main body 5, and the female thread is screwed to the male thread of the outer cylinder of the container main body 1, whereby the stopper main body 5 is attached to the opening end of the container main body 1. The open end of the container body 1 is inserted into a gap formed between the outer wall 5a and the inner wall 5c of the stopper body 5. A drinking mouth 6 is disposed inside the inner wall 5c of the stopper body 5.

飲み口6は、栓本体5に対して着脱可能に嵌め合わされた着脱式のものが採用されている。飲み口6は、図3、4に示すように、中間部分を仕切壁8で塞がれた筒状に形成され、仕切壁8の前側寄りに連通孔9が形成される。飲み口6は栓本体5よりも上下方向に長く形成され、飲み口6の上部および下部は栓本体5から上下にそれぞれ突出している。飲み口6の外周面の下部に、上下一対のシール用フランジが形成され、両フランジ間に環状のシール材10が装着される。シール材10は容器本体1の上部の内周面に密着して、容器本体1の開口が密閉される。このとき、容器本体1の内部と外部とは、飲み口6の仕切壁8に形成された連通孔9により連通される。   As the drinking mouth 6, a detachable type that is detachably fitted to the stopper body 5 is employed. As shown in FIGS. 3 and 4, the drinking mouth 6 is formed in a cylindrical shape whose intermediate portion is closed with a partition wall 8, and a communication hole 9 is formed near the front side of the partition wall 8. The drinking mouth 6 is formed longer in the vertical direction than the stopper body 5, and the upper and lower portions of the drinking mouth 6 protrude vertically from the stopper body 5. A pair of upper and lower sealing flanges are formed at the lower part of the outer peripheral surface of the drinking mouth 6, and an annular sealing material 10 is mounted between the flanges. The sealing material 10 is in close contact with the inner peripheral surface of the upper part of the container body 1, and the opening of the container body 1 is sealed. At this time, the inside and the outside of the container body 1 are communicated with each other through a communication hole 9 formed in the partition wall 8 of the drinking mouth 6.

蓋7は、図3および図6に示すように、飲み口6を覆うように飲み口6よりも大径に形成される。蓋7には連通孔9を塞ぐための栓部11が設けられ、栓部11にパッキン12が被せられている。栓部11は、蓋7の内面側に突設され、飲み口6内に入り込む大きさとされる。この構成によると、蓋7が閉じた状態のとき、栓部11が飲み口6内に入り込み、パッキン12が連通孔9の周縁に密着して、連通孔9が密閉される。   As shown in FIGS. 3 and 6, the lid 7 is formed larger in diameter than the drinking mouth 6 so as to cover the drinking mouth 6. The lid 7 is provided with a plug portion 11 for closing the communication hole 9, and the plug portion 11 is covered with a packing 12. The plug portion 11 protrudes from the inner surface side of the lid 7 and is sized to enter the drinking mouth 6. According to this configuration, when the lid 7 is in the closed state, the stopper portion 11 enters the drinking mouth 6, the packing 12 is brought into close contact with the peripheral edge of the communication hole 9, and the communication hole 9 is sealed.

蓋7は、図2、図3および図6に示すように、栓本体5の上端縁部5bに形成された保持部31によりヒンジ軸30を介して回動可能に設けられる。蓋7を開くと、飲み口6が現れ、蓋7を閉じると、飲み口6が隠れる。蓋7を閉じたとき、蓋7は前側のロック機構13によりロックされ、閉状態に維持される。また、栓本体5の後側の上端縁部5bには、ヒンジ軸30を回動可能に保持する保持部31が上方に向かって突設される。この保持部31に対応して蓋7の後側には軸受32が形成され、この軸受32にヒンジ軸30の左右の端部が嵌められる。保持部31には、ねじりコイルばね(図示せず)が取り付けられ、蓋7は、ねじりコイルばねにより開く方向に付勢される。   As shown in FIGS. 2, 3, and 6, the lid 7 is rotatably provided via a hinge shaft 30 by a holding portion 31 formed on the upper end edge portion 5 b of the plug body 5. When the lid 7 is opened, the drinking mouth 6 appears, and when the lid 7 is closed, the drinking mouth 6 is hidden.

The operation lever 34 can be rotated about the mounting shaft 50 and can be rotated around the fixed shaft 36 integrally with the lock body 33 in the opened state. When the lock body 33 rotates, the locking claw 40 at the tip thereof is disengaged from the locked portion 41 of the lid 7, the lid 7 is unlocked, and the lid 7 is opened. When the operation lever 34 is in the closed state accommodated in the lock body 33, the lock body 33 is held in a state in which it cannot be rotated by a restriction pin 58 described later, and the lid 7 is not opened.

ロック体33は、図11〜15に示すように、その外面側が枠状に形成され、その枠内に操作レバー34が収容されている。ロック体33は、図7に示すように、栓本体5の前側に形成された保持枠35内に固定軸36を介して保持される。保持枠35は、左右一対の側壁によって形成され、ロック体33の左右外側に突出する固定軸36が保持枠35に取り付けられる。固定軸36は、ロック体33の下部に挿着され、固定軸36の左右の両端が保持枠35に形成された軸孔37に嵌め込まれる。固定軸36の一端には、抜け止め用の溝38が形成されている。   As shown in FIGS. 11 to 15, the outer surface side of the lock body 33 is formed in a frame shape, and the operation lever 34 is accommodated in the frame. As shown in FIG. 7, the lock body 33 is held via a fixed shaft 36 in a holding frame 35 formed on the front side of the plug body 5. The holding frame 35 is formed by a pair of left and right side walls, and a fixed shaft 36 protruding to the left and right outer sides of the lock body 33 is attached to the holding frame 35. The fixed shaft 36 is inserted into the lower portion of the lock body 33, and both left and right ends of the fixed shaft 36 are fitted into shaft holes 37 formed in the holding frame 35. At one end of the fixed shaft 36, a retaining groove 38 is formed.

ロック体33の上部の内側に、係止爪40が左右方向に長く形成される。蓋7の前側に、係止爪40に係止される係止突起41が形成される。係止突起41は、係止爪40に対向して左右方向に長く形成される。ロック体33の下部に開口33aが形成される。この開口33aの下端縁に、操作レバー34が当接して一体的に回動するための棒状の当接部42が設けられている。この当接部42は左右方向にわたって形成される。   A locking claw 40 is formed long in the left-right direction inside the upper portion of the lock body 33. A locking projection 41 that is locked to the locking claw 40 is formed on the front side of the lid 7. The locking projection 41 is formed long in the left-right direction so as to face the locking claw 40. An opening 33 a is formed in the lower portion of the lock body 33. A rod-like contact portion 42 is provided at the lower edge of the opening 33a so that the operation lever 34 contacts and rotates integrally. This contact part 42 is formed over the left-right direction.

ロック体33の下端部後面と栓本体5の外壁5aとの間にコイルばね43が介設され、ロック体33を係止爪40の係止方向に付勢される。コイルばね43は、当接部42の後面に突設された左右一対のピン44に嵌め込まれている。当接部42と係止爪40は固定軸36を挟んで上下に配置される。当接部42がコイルばね43に付勢されることにより、係止爪40が栓本体5に当接するように押し付けられる。係止爪40が係止突起41を押さえつけて、蓋7が開かないように係止される。   A coil spring 43 is interposed between the rear surface of the lower end portion of the lock body 33 and the outer wall 5a of the plug body 5, and the lock body 33 is urged in the locking direction of the locking claw 40. The coil spring 43 is fitted into a pair of left and right pins 44 projecting from the rear surface of the contact portion 42. The abutting portion 42 and the locking claw 40 are arranged vertically with the fixed shaft 36 interposed therebetween. When the abutting portion 42 is urged by the coil spring 43, the locking claw 40 is pressed so as to abut on the plug body 5. The locking claw 40 presses the locking projection 41 and is locked so that the lid 7 does not open.

また、蓋7には、係止突起41の上方に、係止爪40の上部を覆う保護枠45が形成されている。蓋7が閉じているとき、不用意に係止爪40に触れないように保護する。保護枠45は左右の保持枠35につながるように湾曲して形成されているので、デザイン的に一体感が得られる。また、左右の保持枠35の間には、液垂れ防止壁46(図7参照)が係止突起41の下方に位置するように形成され、流れ落ちてきた飲料が保持枠35内に入らないようにせき止められる。保持枠35の下部には、目隠し壁47が形成され、保持枠35とロック体33との間に異物が入らないようにされている。   Further, a protective frame 45 that covers the upper portion of the locking claw 40 is formed on the lid 7 above the locking projection 41. When the lid 7 is closed, it is protected from inadvertently touching the locking claw 40. Since the protective frame 45 is curved and formed so as to be connected to the left and right holding frames 35, a sense of unity can be obtained in terms of design. Further, a liquid dripping prevention wall 46 (see FIG. 7) is formed between the left and right holding frames 35 so as to be positioned below the locking projections 41 so that the beverage that has flowed down does not enter the holding frame 35. You can stop. A blindfold wall 47 is formed at the lower part of the holding frame 35 so that no foreign matter enters between the holding frame 35 and the lock body 33.

操作レバー34は、ロック体33の枠内に取付軸50を介して取り付けられる。取付軸50は、固定軸36の下方で、かつ固定軸36の前方に位置する。すなわち、取付軸50は、固定軸36の斜め下前方に接近した位置に配置される。さらに、取付軸50は、ロック体33の当接部42よりも上方に位置する。ロック体33の上部の外側が凹むように形成され、この凹みが操作レバー34を収容する収容部51とされる。収容部51の壁面と操作レバー当接部42の前面とは面一とされる。   The operation lever 34 is attached within the frame of the lock body 33 via the attachment shaft 50. The attachment shaft 50 is located below the fixed shaft 36 and in front of the fixed shaft 36. That is, the attachment shaft 50 is disposed at a position approaching obliquely below and forward of the fixed shaft 36. Further, the mounting shaft 50 is positioned above the contact portion 42 of the lock body 33. The outer side of the upper portion of the lock body 33 is formed to be recessed, and this recess serves as a storage portion 51 for storing the operation lever 34. The wall surface of the accommodating part 51 and the front surface of the operation lever contact part 42 are flush with each other.

操作レバー34の先端部では、外表面が滑らかな面とされ、裏面に凹凸部52が形成される。操作レバー34の基部に円筒部53が形成される。この円筒部53はロック体33の開口33aに臨み、その後部がロック体33の開口33a内に位置する。取付軸50は、円筒部53内を貫通して、ロック体33に形成された左右両側の軸孔54に保持される。操作レバー34は、図4に示すようなロック体33に収容された閉状態から図6及び図16に示すようなロック体33から突出した開状態に回動可能とされる。   At the front end portion of the operation lever 34, the outer surface is a smooth surface, and the uneven portion 52 is formed on the back surface. A cylindrical portion 53 is formed at the base of the operation lever 34. The cylindrical portion 53 faces the opening 33 a of the lock body 33, and the rear portion thereof is located in the opening 33 a of the lock body 33. The attachment shaft 50 penetrates through the cylindrical portion 53 and is held in the left and right shaft holes 54 formed in the lock body 33. The operation lever 34 is rotatable from a closed state accommodated in the lock body 33 as shown in FIG. 4 to an open state protruding from the lock body 33 as shown in FIGS. 6 and 16.

操作レバー34は、閉状態のままロック体33に保持される。円筒部53の後面側に、横長の小溝55が形成され、ロック体33の下部の開口33a内に、円筒部53に接触する保持爪56が弾性変形可能に設けられる。小溝55は、円筒部53の左右方向の中央に位置し、保持爪56は、開口33aの下端縁を形成する当接部42の左右方向中央に配され、後傾するように突設される。操作レバー34が閉状態にあるとき、操作レバー34の円筒部53の小溝55に保持爪56が嵌る。保持爪56は自身の弾性力およびコイルばね43の付勢力により円筒部53に押し付けられる。これにより、操作レバー34は、自重や衝撃などによって開かず、閉状態に保持される。   The operation lever 34 is held by the lock body 33 in a closed state. A laterally small groove 55 is formed on the rear surface side of the cylindrical portion 53, and a holding claw 56 that comes into contact with the cylindrical portion 53 is provided in the opening 33 a below the lock body 33 so as to be elastically deformable. The small groove 55 is located at the center in the left-right direction of the cylindrical portion 53, and the holding claw 56 is disposed at the center in the left-right direction of the abutting portion 42 that forms the lower end edge of the opening 33a, and projects so as to tilt backward. . When the operation lever 34 is in the closed state, the holding claw 56 is fitted in the small groove 55 of the cylindrical portion 53 of the operation lever 34. The holding claw 56 is pressed against the cylindrical portion 53 by its own elastic force and the biasing force of the coil spring 43. As a result, the operation lever 34 is not opened by its own weight or impact, but is held in the closed state.

操作レバー34の先端部とロック体33の上部枠との間には指先を挿入可能な空間(開口)があり、さらに、操作レバー34の先端裏側に基部側に凹む段差がある。また、ロック体33の収容部51の上部はなだらかに傾斜するように形成されており、上記開口、操作レバー先端の段差、および収容部51のなだらかな傾斜によって操作レバー34の先端部とロック体33の上部枠との間の開口に指先を入れやすくなっている。したがって、操作レバー34の上端に指を引っ掛けて、操作レバー34を手前に引くことにより、操作レバー34を下方向に向かって回動させることができる。操作レバー34が回動すると、操作レバー34の基部にある円筒部53が回動することになり、ロック体33側の保持爪56が撓んで小溝55から外れ、操作レバー34を開くことができる。   There is a space (opening) in which a fingertip can be inserted between the distal end portion of the operation lever 34 and the upper frame of the lock body 33, and there is a step that is recessed on the base side behind the distal end side of the operation lever 34. Further, the upper portion of the accommodating portion 51 of the lock body 33 is formed so as to be gently inclined, and the distal end portion of the operation lever 34 and the lock body are formed by the opening, the step at the distal end of the operation lever, and the gentle inclination of the accommodating portion 51. It is easy to put a fingertip into the opening between the upper frame 33. Therefore, the operation lever 34 can be rotated downward by hooking a finger on the upper end of the operation lever 34 and pulling the operation lever 34 forward. When the operation lever 34 is rotated, the cylindrical portion 53 at the base of the operation lever 34 is rotated, and the holding claw 56 on the lock body 33 side is bent and detached from the small groove 55, so that the operation lever 34 can be opened. .

一方、操作レバー34の円筒部53の前面側には、小溝55よりも大きい横長の大溝57が形成されている。この大溝57は、円筒部53の左右方向にわたって形成され、操作レバー34の下回動時に規制ピン58の侵入を許して、操作レバー34のさらなる下回動を許容する大きさに設定されている。   On the other hand, a laterally large groove 57 larger than the small groove 55 is formed on the front side of the cylindrical portion 53 of the operation lever 34. The large groove 57 is formed in the left-right direction of the cylindrical portion 53, and is set to a size that allows the restriction pin 58 to enter when the operation lever 34 is rotated downward and allows the operation lever 34 to further rotate downward. .

図7に示すように、栓本体5の保持枠35内に左右一対の規制ピン58が突設されている。一対の規制ピン58は、ロック体33の開口33aに合わせて枠本体5の外壁5aから突出し、円筒部53の小溝55よりも左右方向で外側にある円筒部53に対向して配置される。ロック体33の保持爪56は、左右の規制ピン58の間に位置し、小溝55に対向している。規制ピン58は、操作レバー34の円筒部53の大溝57に侵入可能な位置に配置される。   As shown in FIG. 7, a pair of left and right regulating pins 58 project from the holding frame 35 of the plug body 5. The pair of restricting pins 58 protrude from the outer wall 5 a of the frame body 5 in accordance with the opening 33 a of the lock body 33, and are disposed to face the cylindrical portion 53 that is outside in the left-right direction with respect to the small groove 55 of the cylindrical portion 53. The holding claw 56 of the lock body 33 is located between the left and right regulating pins 58 and faces the small groove 55. The restriction pin 58 is disposed at a position where it can enter the large groove 57 of the cylindrical portion 53 of the operation lever 34.

操作レバー34が閉状態にあるとき、規制ピン58は円筒部53の後側に対向している。このとき、操作レバー34の円筒部53が後方に押されると、ロック体33は固定軸36周りに係止爪40を係止突起41から外れる前方向に回動しようとするが、操作レバー34の円筒部53の後方には規制ピン58があるので、この規制ピン58に円筒部53が当接する。そのため、ロック体33の当接部42は少しだけ内側に向かって押されるだけである。すなわち、規制ピン58により、ロック体33を押せないように操作レバー34の動きが規制される。ロック体33は回動しないので、ロック体33の係止爪40は蓋7の係止突起41に係止されたままとなり、蓋7のロックは解除されない。したがって、蓋7が閉まっているときに、操作レバー34が押されてもロックは解除されず、蓋7が不用意に開くことを防止できる。   When the operation lever 34 is in the closed state, the restriction pin 58 faces the rear side of the cylindrical portion 53. At this time, when the cylindrical portion 53 of the operation lever 34 is pushed rearward, the lock body 33 tries to rotate the locking claw 40 around the fixed shaft 36 in the forward direction away from the locking projection 41. Since there is a restriction pin 58 behind the cylindrical portion 53, the cylindrical portion 53 comes into contact with the restriction pin 58. Therefore, the contact part 42 of the lock body 33 is only pushed inward slightly. That is, the movement of the operation lever 34 is restricted by the restriction pin 58 so that the lock body 33 cannot be pushed. Since the lock body 33 does not rotate, the engagement claw 40 of the lock body 33 remains engaged with the engagement protrusion 41 of the lid 7 and the lock of the lid 7 is not released. Therefore, even when the operation lever 34 is pressed when the lid 7 is closed, the lock is not released, and the lid 7 can be prevented from being opened carelessly.

閉状態の操作レバー34を開くように回動操作をすると、操作レバー34の前面に設けられた押圧部59がロック体33の当接部42に当接し、操作レバー34が開状態となる(図16参照)。このとき、操作レバー34の凹凸部52が前側を向き、規制ピン58は大溝57に対向する。そして、凹凸部52は押圧部59および当接部42よりも下方に位置する、すなわち押圧部59よりも取付軸50から遠くに位置する。そのまま、操作レバー34の凹凸部52を押すと、図17に示すように、操作レバー34がさらに下回動し、コイルばね43の付勢力に抗してロック体33の当接部42が操作レバー34の押圧部59により後側に押される。   When the rotation operation is performed so as to open the operation lever 34 in the closed state, the pressing portion 59 provided on the front surface of the operation lever 34 contacts the contact portion 42 of the lock body 33, and the operation lever 34 is in the open state ( (See FIG. 16). At this time, the concavo-convex portion 52 of the operation lever 34 faces the front side, and the regulation pin 58 faces the large groove 57. The uneven portion 52 is located below the pressing portion 59 and the contact portion 42, that is, located farther from the mounting shaft 50 than the pressing portion 59. If the concave and convex portion 52 of the operating lever 34 is pushed as it is, the operating lever 34 is further rotated downward as shown in FIG. 17, and the abutting portion 42 of the lock body 33 is operated against the urging force of the coil spring 43. It is pushed rearward by the pushing portion 59 of the lever 34.

このとき、操作レバー34の円筒部53が栓本体5の外壁5a側に近付くが、外壁5aから前方に突出する規制ピン58が円筒部53の大溝57に入り込み、操作レバー34の回動を妨げない。よって、ロック体33が固定軸36を中心に回動し、その係止爪40が前方に移動して、蓋7の係止突起41から離れる。蓋7のロックが解除されると、蓋7は、ねじりコイルばねの付勢力により開く。操作レバー34から指を離して回動操作をやめると、図3に示すように、コイルばね43の付勢力によりロック体33の当接部42が押し戻され、ロック体33は元の状態に戻り、操作レバー34は開状態に戻る。   At this time, the cylindrical portion 53 of the operation lever 34 approaches the outer wall 5a side of the plug body 5, but the restriction pin 58 protruding forward from the outer wall 5a enters the large groove 57 of the cylindrical portion 53, thereby preventing the operation lever 34 from rotating. Absent. Therefore, the lock body 33 rotates around the fixed shaft 36, and the locking claw 40 moves forward and moves away from the locking projection 41 of the lid 7. When the lid 7 is unlocked, the lid 7 is opened by the biasing force of the torsion coil spring. When the finger is released from the operation lever 34 and the rotation operation is stopped, as shown in FIG. 3, the contact portion 42 of the lock body 33 is pushed back by the biasing force of the coil spring 43, and the lock body 33 returns to the original state. The operation lever 34 returns to the open state.

開状態の操作レバー34の先端を押し上げるように上回動すると、操作レバー34は取付軸50周りに上回動してロック体33に収容された閉状態になる。この状態で、蓋7を閉めると、係止突起41がロック体33の係止爪40に当たり、ロック体33の上部が前側に向かって押し出される。そして、蓋7が閉じると、コイルばね43の付勢力によってロック体33が回動し、係止突起41に係止爪40が嵌り、蓋7が閉状態でロックされる。   When the upper lever 34 is turned upward to push up the tip of the operation lever 34 in the open state, the operation lever 34 is turned upward around the attachment shaft 50 to be in the closed state accommodated in the lock body 33. When the lid 7 is closed in this state, the locking projection 41 hits the locking claw 40 of the lock body 33 and the upper portion of the lock body 33 is pushed out toward the front side. When the lid 7 is closed, the lock body 33 is rotated by the urging force of the coil spring 43, the locking claw 40 is fitted into the locking projection 41, and the lid 7 is locked in the closed state.

上記のように、操作レバー34に対して回動操作を行うだけで、蓋7のロックを解除して、蓋7を開くことができる。すなわち、指先だけで操作レバー34の回動操作を行えるので、簡単な操作で蓋7のロック解除から開放まで行え、使い勝手がよくなる。また、蓋7を開けるとき、ロック体33の係止爪40と当接部42とが固定軸36を挟んで上下に位置するようになっているので、係止爪40が作用点、固定軸36が支点、当接部42が力点となる。操作レバー34の押圧部59を通じて当接部42に力を加えると、当接部42と操作レバー34とが一体となり、操作レバー34の先端が力点として機能することになる。よって、力点となる操作レバー34の先端と支点となる固定軸36との距離が長くなり、てこの原理を利用して小さな力でロック体33を回動でき、ロックを解除することが容易に行える。   As described above, the lid 7 can be unlocked and the lid 7 can be opened simply by rotating the operation lever 34. That is, since the operation lever 34 can be turned only with the fingertip, the lid 7 can be unlocked and released with a simple operation, and the usability is improved. Further, when the lid 7 is opened, the locking claw 40 and the contact portion 42 of the lock body 33 are positioned above and below the fixed shaft 36, so that the locking claw 40 acts on the fixed point and the fixed shaft. 36 is a fulcrum, and the contact portion 42 is a power point. When a force is applied to the contact portion 42 through the pressing portion 59 of the operation lever 34, the contact portion 42 and the operation lever 34 are integrated, and the tip of the operation lever 34 functions as a power point. Therefore, the distance between the tip of the operation lever 34 serving as a power point and the fixed shaft 36 serving as a fulcrum is increased, and the lock body 33 can be rotated with a small force using the lever principle, and the lock can be easily released. Yes.

すなわち、取付軸50が固定軸36よりも下方に位置し、操作レバー34の凹凸部52が押圧部59よりも取付軸50から離れた位置にあるので、間接的に力点が支点から遠い位置となり、小さな力でロック体33を回動させることができ、蓋7の開放を容易に行うことができる。   That is, since the mounting shaft 50 is located below the fixed shaft 36 and the uneven portion 52 of the operation lever 34 is located farther from the mounting shaft 50 than the pressing portion 59, the force point is indirectly far from the fulcrum. The lock body 33 can be rotated with a small force, and the lid 7 can be easily opened.

次に、着脱式の飲み口6について説明する。筒状の飲み口6は、栓本体5の筒状の内壁5cに対して上下方向に移動可能に内嵌されている。ただし、飲み口6の上下方向で中間部の外周壁には、半径方向外側に突出する外周フランジ6aが形成され、この外周フランジ6aが栓本体5の内壁5cの下端に下方から当接して、飲み口6の上方への移動を規制するようにしている。さらに、飲み口6の外周面の左右両側には、外周フランジ6aの一部を取り除いて凹状に形成された凹部14が形成され、この凹部14に飲み口6を栓本体5に対して下方に移動しないように規制する規制体15が収容される。規制体15は左右一対に設けられる。各規制体15は、支軸16周りに揺動可能に支持され、凹部14から半径方向外側へ突出可能とされる。   Next, the removable drinking mouth 6 will be described. The cylindrical drinking mouth 6 is fitted into the cylindrical inner wall 5c of the stopper body 5 so as to be movable in the vertical direction. However, an outer peripheral flange 6a projecting radially outward is formed on the outer peripheral wall of the middle portion in the vertical direction of the drinking mouth 6, and this outer peripheral flange 6a abuts on the lower end of the inner wall 5c of the plug body 5 from below, The upward movement of the drinking mouth 6 is restricted. Further, on both the left and right sides of the outer peripheral surface of the drinking mouth 6, a concave portion 14 is formed by removing a part of the outer peripheral flange 6 a, and the drinking mouth 6 is placed below the stopper body 5 in the concave portion 14. A restricting body 15 that restricts movement is accommodated. The regulating body 15 is provided in a pair of left and right. Each restricting body 15 is supported so as to be swingable around the support shaft 16, and can be protruded radially outward from the recess 14.

各規制体15は、図8および図9に示すように、栓本体5の上端縁部に係合して飲み口6の下方への移動を阻止するフック17と、このフック17を飲み口6の半径方向外側に付勢する弾性変形可能な弾性片18とを備えている。   As shown in FIGS. 8 and 9, each regulating body 15 is engaged with the upper end edge of the stopper body 5 to prevent the drinking mouth 6 from moving downward, and the hook 17 is used as the drinking mouth 6. And an elastically deformable elastic piece 18 that is urged radially outward.

フック17は、上部側が外側に膨らんだ頭部17aと、中間の胴部17bと、二股の脚部17cとを有する。頭部17aと胴部17bとの境界部には、栓本体5の上端縁部5bに係合する段差17dが形成されている。頭部17aは、その前後方向中央に飲み口6を栓本体5から取り外すときに、規制体15を飲み口6の凹部14側に後退させるよう操作する摘み部21を有している。   The hook 17 has a head portion 17a whose upper side bulges outward, an intermediate trunk portion 17b, and a bifurcated leg portion 17c. A step 17d that engages with the upper end edge 5b of the plug body 5 is formed at the boundary between the head 17a and the trunk 17b. The head 17a has a knob 21 at the center in the front-rear direction for operating the regulating body 15 to retreat toward the recess 14 of the drinking mouth 6 when the drinking mouth 6 is removed from the stopper body 5.

栓本体5の内壁5cには、飲み口6を栓本体5に取り付ける際に摘み部21を挿入して上下方向への移動を案内する縦溝22が形成されている。摘み部21の両側に、縦溝22の両側の内壁5cに沿って案内されるガイド部17eが形成されている。このガイド部17eは、栓本体5の内壁5cの下端から上方に案内しやすいように、上方に向かうほど栓本体5の外壁側に向かう湾曲状の傾斜面とされている。ガイド部17eの下端に位置する段差17dは、栓本体5の上端縁部5bに形成された凹状の段部25に係止される。   A longitudinal groove 22 is formed in the inner wall 5c of the stopper body 5 to insert the knob 21 when the drinking mouth 6 is attached to the stopper body 5 and guide the movement in the vertical direction. Guide portions 17e that are guided along the inner walls 5c on both sides of the longitudinal groove 22 are formed on both sides of the knob portion 21. The guide portion 17e is a curved inclined surface that faces the outer wall side of the plug body 5 as it goes upward so that it can be easily guided upward from the lower end of the inner wall 5c of the plug body 5. The step 17d located at the lower end of the guide portion 17e is locked to a concave step portion 25 formed on the upper end edge 5b of the plug body 5.

前後に配された脚部17cの各下端部には、凹部14にフック17の下端部を揺動可能に支持するための軸受部26が形成されている。軸受部26の軸孔27には、飲み口6の凹部14の側壁に突設された支軸16が差し込まれる。これにより、規制体15が支軸16周りに揺動可能とされる。軸受部26の背面側に、二股の脚部17cのわずかな弾性により軸孔27に支軸16を無理嵌めできるようにテーパ面26aが形成されている。また、軸受部26は、凹部14より外側にわずかに突出して、飲み口6の外周フランジ6aと共に、栓本体5の内壁5cに当接して、飲み口6の上動を規制するようになっている。   A bearing portion 26 for supporting the lower end portion of the hook 17 in the recess 14 so as to be swingable is formed in each lower end portion of the leg portion 17c arranged in the front and rear direction. A support shaft 16 protruding from the side wall of the recess 14 of the drinking mouth 6 is inserted into the shaft hole 27 of the bearing portion 26. As a result, the restricting body 15 can swing around the support shaft 16. A tapered surface 26a is formed on the back side of the bearing portion 26 so that the support shaft 16 can be forcibly fitted in the shaft hole 27 by the slight elasticity of the bifurcated leg portion 17c. Moreover, the bearing part 26 protrudes slightly outside the recessed part 14, and contacts the inner wall 5c of the stopper main body 5 together with the outer peripheral flange 6a of the drinking mouth 6, thereby restricting the upward movement of the drinking mouth 6. Yes.

軸受部26の後側には、前後方向からみて脚部17cとによりV字状になるように弾性片18が一体的に形成されている。この弾性片18は、凹部14の後壁に当接して、フック17を外側に付勢するように機能する。したがって、凹部14に収容されたフック17の頭部17aは、支軸16周りに飲み口6の半径方向外側に突出するよう付勢される。   An elastic piece 18 is integrally formed on the rear side of the bearing portion 26 so as to be V-shaped with the leg portion 17c when viewed from the front-rear direction. The elastic piece 18 functions to abut against the rear wall of the recess 14 and bias the hook 17 outward. Accordingly, the head portion 17 a of the hook 17 accommodated in the recess 14 is biased so as to protrude outward in the radial direction of the drinking mouth 6 around the support shaft 16.

図5に示すように、フック17の胴部17bは栓本体5の内壁5cの内周面に接触する。図6、7に示すように、栓本体5の内壁5cの左右両側には、規制体15の摘み部21が通る縦溝22が形成されており、摘み部21が縦溝22に沿って上下方向に移動可能とされる。また、栓本体5の内壁5cの後側にはガイド溝23が形成される。このガイド溝23には、栓本体5の後側の外周面に突設されたリブ24(図3参照)が上下方向に移動可能に嵌合される。これらの溝22,23により、飲み口6を栓本体5に対して着脱するとき、飲み口6がガイドされる。   As shown in FIG. 5, the body portion 17 b of the hook 17 contacts the inner peripheral surface of the inner wall 5 c of the plug body 5. As shown in FIGS. 6 and 7, vertical grooves 22 through which the knob portion 21 of the regulating body 15 passes are formed on the left and right sides of the inner wall 5 c of the plug body 5, and the knob portion 21 is vertically moved along the vertical groove 22. It is possible to move in the direction. A guide groove 23 is formed on the rear side of the inner wall 5 c of the plug body 5. In this guide groove 23, a rib 24 (see FIG. 3) protruding from the outer peripheral surface on the rear side of the plug body 5 is fitted so as to be movable in the vertical direction. By these grooves 22, 23, the mouth 6 is guided when the mouth 6 is attached to and detached from the stopper body 5.

飲み口6を栓本体5から外すとき、左右両側の2つの規制体15の摘み部21を両側から挟むように持つ。そうすると、フック17が栓本体5の段部25から離れる半径方向内側に移動して、栓本体5によるフック17の係合が外れ、飲み口6が下方向に移動可能となる。なお、フック17が移動しても、フック17の軸受部26および飲み口6の外周フランジ6aが栓本体5の内壁5cの下端に当接しているので、飲み口6は上方向に移動できない。摘み部21を掴んだまま飲み口6を栓本体5に対して下方に下げる、あるいは栓本体5を飲み口6に対して上げると、フック17が栓本体5の内周面に接触しながら飲み口6が移動し、飲み口6を栓本体5から外すことができる。   When the drinking mouth 6 is removed from the stopper body 5, the knobs 21 of the two regulating bodies 15 on both the left and right sides are sandwiched from both sides. Then, the hook 17 moves inward in the radial direction away from the step portion 25 of the plug body 5, the hook 17 is disengaged by the plug body 5, and the drinking mouth 6 can move downward. Even if the hook 17 moves, the bearing portion 26 of the hook 17 and the outer peripheral flange 6a of the drinking mouth 6 are in contact with the lower end of the inner wall 5c of the stopper body 5, so that the drinking mouth 6 cannot move upward. When the drinking mouth 6 is lowered downward with respect to the stopper body 5 while holding the knob 21, or when the stopper body 5 is raised with respect to the drinking mouth 6, the hook 17 drinks while contacting the inner peripheral surface of the stopper body 5. The mouth 6 moves and the drinking mouth 6 can be removed from the stopper body 5.

飲み口6を栓本体5に取り付けるとき、飲み口6を栓本体5の下方から差し込む。飲み口6のリブ24をガイド溝23に合わせて、飲み口6を栓本体5に対して上方向に移動させる。そうすると、フック17が縦溝22の下縁に当たって、フック17が飲み口6に近づく半径方向内側に移動し、フック17の頭部17aにあるガイド部17eが栓本体5の内壁5cに接触しながら飲み口6が栓本体5に対して移動する。フック17の頭部17aが縦溝22の上縁に達すると、フック17の軸受部26が栓本体5の内壁5cの下縁に当接する。弾性片18の弾性力によりフック17が栓本体5の内壁5c側に近づく方向に移動し、フック17の段差部17dが段部25に引っ掛かり栓本体5に係合される。フック17は弾性片18によって栓本体5に押し付けられるので、飲み口6は、栓本体5に上下方向に移動できないように係止される。このとき、カチッと音がするので、飲み口6が係止されたことを認識することができる。なお、栓本体5を飲み口6に対して上方から差し込むことによっても、飲み口6を栓本体5に取り付けることができる。   When attaching the drinking mouth 6 to the stopper body 5, the drinking mouth 6 is inserted from below the stopper body 5. The rib 24 of the drinking mouth 6 is aligned with the guide groove 23 and the drinking mouth 6 is moved upward with respect to the stopper body 5. Then, the hook 17 hits the lower edge of the longitudinal groove 22, the hook 17 moves inward in the radial direction approaching the drinking mouth 6, and the guide portion 17 e on the head portion 17 a of the hook 17 is in contact with the inner wall 5 c of the plug body 5. The drinking mouth 6 moves relative to the stopper body 5. When the head portion 17a of the hook 17 reaches the upper edge of the longitudinal groove 22, the bearing portion 26 of the hook 17 comes into contact with the lower edge of the inner wall 5c of the plug body 5.

Then, the drinking mouth 6 can be attached to the stopper body 5 by inserting the drinking mouth 6 into the stopper body 5. Therefore, since the drinking mouth 6 can be easily attached and detached, the drinking mouth 6 can be easily cleaned. Further, the drinking mouth 6 can be exchanged, and the drinking mouth 6 can be used for other beverage containers, and the drinking mouth 6 suitable for the user can be provided.

なお、本考案は、上記実施形態に限定されるものではなく、本発明の範囲内で上記実施形態に多くの修正および変更を加え得ることは勿論である。例えば、飲み口6の規制体15を飲み口6の上縁から上方に突出するように設けてもよい。これにより、規制体15を摘みやすくなる。また、規制体15は支持16周りに揺動する形態を示したが、これに限らず、フック17を水平方向で出退可能な構成としてもよい。   In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added to the said embodiment within the scope of the present invention. For example, the regulating body 15 of the drinking mouth 6 may be provided so as to protrude upward from the upper edge of the drinking mouth 6. Thereby, it becomes easy to pick the regulation body 15. Moreover, although the regulation body 15 showed the form rock | fluctuated around the support 16, it is good not only as this but the structure which can move the hook 17 in a horizontal direction.
