Description

この発明は、水筒、マグボトル、魔法瓶等、飲料を持ち運びするために使用される携帯飲料容器に関する。 The present invention relates to a portable beverage container used for carrying a beverage such as a water bottle, a mug bottle, a thermos bottle or the like.

携帯飲料容器は、所定容量の飲料を容器本体に収容し、その容器本体を栓及び蓋で密封するようになっている。容器本体は、底面部で水平面上に鉛直に立てることができるようになっている。容器本体の上面に容器口が開口している。容器本体の上部に栓カバーが装着されている。栓カバーに開口している流路口が容器口に連通している。容器本体に収容された飲料は、流路口から外部に流出させるようになっている。栓カバーは、望ましい形状の流出経路を作るために、容器本体と別体になっている。流路口を密封する栓、及び流路口は、栓カバーと蓋とによって外部から保護されている。 A portable beverage container accommodates a predetermined volume of beverage in a container body, and the container body is sealed with a stopper and a lid. The container main body can stand vertically on a horizontal surface at the bottom surface. A container opening is opened on the upper surface of the container body. A stopper cover is attached to the top of the container body. A channel port opening in the stopper cover communicates with the container port. The beverage accommodated in the container body is allowed to flow out from the channel opening. The stopper cover is separated from the container body in order to create a desired shape of the outflow path. The stopper that seals the channel opening, and the channel opening are protected from the outside by a stopper cover and a lid.

中でも、栓カバーに対してヒンジ軸回りに回動可能な蓋を採用し、その蓋に栓を設けたものがある。この場合、蓋の閉回転を利用して流路口を栓で密封することができる。また、蓋の開回転を自動的に阻止する機構を備えることにより、密封を確実にすることができる。 Among them, there is a type that employs a lid that can rotate about a hinge axis with respect to the plug cover, and the lid is provided with the lid. In this case, the channel opening can be sealed with a stopper using the closed rotation of the lid. Moreover, sealing can be ensured by providing a mechanism that automatically prevents the lid from rotating open.

その機構として、従来、蓋に係止部材と弾性部材と操作部とを設け、栓カバーに受け部を設けたものがある。係止部材が受け部と引っ掛かる閉成位置において、前記密封が維持されるようになっている。係止部材は、蓋の閉回転中に受け部と接触することによって、閉成位置から外される。この後、弾性部材の弾性反発力によって、係止部材は、閉成位置へ押し戻されて受け部に引っ掛かる。操作部は、係止部材に操作力を伝えて閉成位置から外すことができる。この操作部により、閉じた蓋の開回転を可能にしている。係止部材、受け部、弾性部材及び操作部の付近は複雑な形態になる。これら係止部材等は、容器本体内の飲料で汚れることを避けるため、栓によって得られる密封の外側に位置している（特許文献１）。 As the mechanism, there is a conventional mechanism in which a lid is provided with a locking member, an elastic member, and an operation portion, and a stopper cover is provided with a receiving portion. The sealing is maintained in a closed position where the locking member is caught by the receiving portion. The locking member is removed from the closed position by contacting the receiving portion during the closing rotation of the lid. Thereafter, the locking member is pushed back to the closed position by the elastic repulsive force of the elastic member and hooked on the receiving portion. The operating portion can be removed from the closed position by transmitting an operating force to the locking member. With this operation unit, the closed lid can be opened. The vicinity of the locking member, the receiving portion, the elastic member, and the operation portion is complicated. These locking members and the like are located outside the seal obtained by the stopper in order to avoid contamination with the beverage in the container body (Patent Document 1).

特開２０１１−９８７８１号公報（特に段落００２０、図１〜図６）Japanese Patent Laying-Open No. 2011-98781 (particularly paragraph 0020, FIGS. 1 to 6)

しかしながら、特許文献１の携帯飲料容器では、一つの係止部材が閉成位置から外れる方向は、専らヒンジ軸に直角かつ水平な一直線方向（いわば製品の前後方向）になっている。このため、携帯飲料容器が落下した場合、その落下の衝撃を受ける方向と、係止部材が閉成位置から外れる方向が一致し得る。これら両方向が一致した場合、弾性部材が衝撃に抵抗し切れず、係止部材が閉成位置から外れ、蓋が開いてしまう可能性がある。 However, in the portable beverage container of Patent Document 1, the direction in which one locking member is removed from the closed position is a straight line direction that is perpendicular to the hinge axis and horizontal (in other words, the front-rear direction of the product). For this reason, when a portable drink container falls, the direction which receives the impact of the fall and the direction from which a latching member remove | deviates from a closed position may correspond. If these two directions match, the elastic member may not resist the impact, and the locking member may come off from the closed position and the lid may open.

そこで、この発明が解決しようとする課題は、蓋側の係止部材及び弾性部材と栓カバーの受け部とを用いて蓋の開回転を自動的に阻止可能な携帯飲料容器が落下した場合でも、蓋が容易に開かないようにすることである。 Accordingly, the problem to be solved by the present invention is that even when a portable beverage container that can automatically prevent the lid from rotating open using the lid-side locking member and elastic member and the stopper cover receiving portion falls. It is to prevent the lid from opening easily.

上記の課題を解決するため、この発明は、上面に容器口が開口している容器本体と、前記容器本体に装着された状態で前記容器口に連通する流路口が開口している栓カバーと、前記栓カバーに対してヒンジ軸回りに回動可能な蓋とを備え、前記蓋は、前記流路口を密封する栓と、前記栓カバーの受け部に引っ掛かって当該蓋の開回転を阻止する係止部材と、前記受け部と引っ掛かる閉成位置から外れた前記係止部材を自己の弾性反発力によって当該閉成位置まで押し戻す弾性部材とを有し、前記係止部材が、前記蓋の閉回転中に前記受け部との接触によって前記閉成位置から外され、前記弾性部材に押し戻されて前記受け部に引っ掛かる携帯飲料容器において、前記係止部材の回転動作、及び二つ以上の前記係止部材又は前記係止部材とこれを閉成位置に規制するロック部材からなる二部材が複数方向に動く動作のうち、少なくとも一つの動作を必須条件として、前記蓋の開回転が可能になる構成を採用した。 In order to solve the above-described problems, the present invention includes a container body having a container opening on an upper surface, a stopper cover having a flow passage opening communicating with the container opening in a state of being attached to the container body, A lid that is rotatable about a hinge axis with respect to the plug cover, and the lid is hooked on a stopper that seals the flow path port and a receiving portion of the plug cover to prevent the lid from opening. A locking member; and an elastic member that pushes the locking member out of the closed position hooked to the receiving portion to the closed position by its own elastic repulsive force, and the locking member closes the lid. In a portable beverage container that is removed from the closed position by contact with the receiving part during rotation and is pushed back by the elastic member and hooked on the receiving part, the rotating operation of the locking member and the two or more engagements Stop member or the locking member and this Of the operations two members consisting of the locking member for restricting the closed position moves in multiple directions, as a prerequisite at least one operation, employing the structure allowing the opening rotation of said lid.

落下の衝撃は、携帯飲料容器に対して衝突開始点から一方向の直線方向に作用する。その一方向は、容器内側を向くが、様々となる。蓋の開回転が可能になる条件とは、蓋に一つ以上備わる全ての係止部材が自己の閉成位置から外れた状態になることである。この状態になる必須条件として、係止部材の回転動作を採用すれば、衝撃がどの一方向に作用するとしても、当該係止部材が閉成位置から外れる方向に一致しないようにすることができる。すなわち、当該係止部材が衝撃で閉成位置から外れ難くなる。また、必須条件として、二つ以上の係止部材又は係止部材とこれを閉成位置に規制するロック部材からなる二部材が複数方向に動く動作を採用すれば、衝撃がどの一方向に作用するとしても、一つの係止部材が閉成位置から外れる方向又はロック部材が規制位置から外れる方向に一致しないようにすることができる。すなわち、当該係止部材が衝撃で閉成位置から外れ難くなる。したがって、蓋の開回転が可能になる必須条件として、前記係止部材の回転動作及び前記二部材が複数方向に動く動作のうち、少なくとも一つの動作を採用しておけば、携帯飲料容器が落下した場合でも、蓋が容易に開かないようにすることができる。 The impact of the drop acts on the portable beverage container in one linear direction from the collision start point. The one direction faces the inside of the container but varies. The condition that the lid can be opened is that all the locking members provided in the lid are out of their closed positions. As an indispensable condition for achieving this state, if the rotation operation of the locking member is adopted, it is possible to prevent the locking member from being coincident with the direction deviating from the closed position no matter which direction the impact acts. . That is, it becomes difficult for the locking member to come off the closed position due to an impact. In addition, as an essential condition, if an operation in which two members including two or more locking members or a locking member and a lock member that restricts the locking member to a closed position is moved in a plurality of directions is adopted, the impact acts in any one direction. Even so, it is possible to prevent the one locking member from being coincident with the direction in which the locking member is removed from the closed position or the direction in which the lock member is removed from the restricting position. That is, it becomes difficult for the locking member to come off the closed position due to an impact. Therefore, as an indispensable condition for opening the lid, if the at least one of the rotation operation of the locking member and the movement of the two members in a plurality of directions is adopted, the portable beverage container falls. Even in this case, the lid can be prevented from easily opening.

前記栓カバーは、前記閉成位置から外れた前記係止部材と上下に接触する上昇面を有し、前記係止部材を前記閉成位置から外す操作の継続によって当該係止部材が前記上昇面に乗り上げさせられ、前記蓋が当該係止部材に押されることによって強制的に開回転させられることが好ましい。密封の内側は、栓によって密封された空間なので、気密性も高い。熱い飲料を容器本体に収容した場合、時間の経過に伴って飲料が冷めるので、その空間の内圧が徐々に低下する。長時間に亘って蓋を開けない場合、内圧の低下が進み、大気圧に比して、内圧が負圧になり得る。この負圧下では、全ての係止部材が閉成位置から外れても、蓋が負圧に吸引される。このため、蓋の開回転が阻害される。係止部材を閉成位置から外した後、蓋が強制的に開回転させられる仕組みを設けておけば、負圧時の蓋開けが容易になる。係止部材を閉成位置から外す操作の継続は、使用者にとって自然な連続操作となる。その継続する操作力によって係止部材が栓カバーの上昇面に乗り上げさせられ、蓋がその係止部材によって押されるようにすれば、その継続する操作力が蓋の開回転トルクに変換される。これにより、使用者は、自然と蓋を強制的に開回転させることができる。蓋が少しでも開回転すれば、前記密封が破れるので、負圧が急速に解消される。したがって、負圧時の蓋開けが容易になる。 The stopper cover has an ascending surface that comes into contact with the engaging member released from the closed position in the up-and-down direction, and the engaging member is removed from the ascending surface by continuing the operation of removing the engaging member from the closed position. It is preferable that the lid is forcibly opened and rotated by being pushed by the locking member. Since the inside of the seal is a space sealed by a stopper, it is highly airtight. When a hot beverage is accommodated in the container body, the beverage cools with time, so that the internal pressure of the space gradually decreases. When the lid cannot be opened for a long time, the internal pressure decreases, and the internal pressure can be a negative pressure compared to the atmospheric pressure. Under this negative pressure, even if all the locking members are removed from the closed position, the lid is sucked into the negative pressure. For this reason, the opening rotation of the lid is hindered. If a mechanism for forcibly opening and closing the lid after removing the locking member from the closed position is provided, it is easy to open the lid at the time of negative pressure. The continuation of the operation of removing the locking member from the closed position is a natural continuous operation for the user. If the locking member is ridden on the rising surface of the stopper cover by the continuous operating force and the lid is pushed by the locking member, the continuous operating force is converted into the opening rotation torque of the lid. Thereby, the user can forcefully open and rotate the lid. If the lid is rotated even a little, the seal is broken, so that the negative pressure is quickly eliminated. Accordingly, it is easy to open the lid at the time of negative pressure.

前記蓋は、回動可能な前記係止部材を一つだけ有し、前記係止部材が前記閉成位置から外れるまで回転する前記回転動作のみによって、前記蓋の開回転が可能になり、前記係止部材に前記回転動作を生じさせるための操作レバーが設けられていることが好ましい。操作レバーで一つの係止部材を回す回転動作のみのシンプルな構造で、この発明を実現することができる。 The lid has only one locking member that can rotate, and the lid can be opened and rotated only by the rotation operation that rotates until the locking member is removed from the closed position. It is preferable that an operation lever for causing the locking member to cause the rotation operation is provided. The present invention can be realized with a simple structure of only a rotating operation in which one locking member is rotated by an operation lever.

前記操作レバーは、前記蓋の天面のヒンジ軸側に位置していることが好ましい。前記容器本体を把持している手の人差し指で操作レバーを回転させることができる。 The operation lever is preferably located on the hinge shaft side of the top surface of the lid. The operation lever can be rotated with the index finger of the hand holding the container body.

また、前記操作レバーは、前記蓋の天面のヒンジ軸方向片側に位置し、かつヒンジ軸側へ回す操作で前記回転動作を生じさせるように設けられていてもよい。この場合、蓋を開くとき、操作レバーを回す方向と、蓋が開回転する方向が同側になる。このため、操作レバーを回す指がヒンジ軸側に近づくことになる。したがって、操作レバーを回す指が蓋の開回転の邪魔にならず、スムーズに蓋を開くことができる。 The operation lever may be provided so as to be positioned on one side of the top surface of the lid in the hinge axis direction and to cause the rotation operation by an operation of turning to the hinge axis side. In this case, when the lid is opened, the direction in which the operation lever is rotated and the direction in which the lid is opened are on the same side. For this reason, the finger turning the operating lever approaches the hinge shaft side. Therefore, the finger that rotates the operation lever does not obstruct the opening rotation of the lid, and the lid can be opened smoothly.

前記係止部材、前記受け部及び前記弾性部材は前記密封の外側に位置していることが好ましい。容器本体に収容した飲料によって係止部材等が汚れないようにすることができる。このため、係止部材等の作動機構をシールすることが不要になる。 It is preferable that the locking member, the receiving portion, and the elastic member are located outside the seal. It is possible to prevent the locking member and the like from being soiled by the beverage stored in the container body. For this reason, it is not necessary to seal an operating mechanism such as a locking member.

上述のように、この発明は、上記構成の採用により、蓋側の係止部材及び弾性部材と栓カバーの受け部とを用いて蓋の開回転を自動的に阻止可能な携帯飲料容器が落下した場合でも、閉成位置から外れ難い係止部材が存在するため、蓋が容易に開かないようにすることができる。 As described above, according to the present invention, by adopting the above configuration, the portable beverage container that can automatically prevent the lid from rotating open using the lid side locking member and the elastic member and the stopper cover receiving portion falls. Even in this case, since there is a locking member that is difficult to be removed from the closed position, the lid can be prevented from being easily opened.

以下、この発明の第１実施形態に係る携帯飲料容器を添付図面に基いて説明する。この携帯飲料容器は、図２〜図４に示すように、上面に容器口１が開口している容器本体２と、流路口３が開口している栓カバー４と、栓カバー４に対してヒンジ軸５回りに回動可能な蓋６と、コップ７とを備えている。流路口３は、容器本体２に装着された状態で容器口１に連通する。 Hereinafter, a portable beverage container according to a first embodiment of the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 2 to 4, the portable beverage container has a container body 2 having a container opening 1 opened on the upper surface, a plug cover 4 having a flow path port 3 opened, and a plug cover 4. A lid 6 that can rotate about the hinge shaft 5 and a cup 7 are provided. The flow path port 3 communicates with the container port 1 while being attached to the container body 2.

容器本体２は、水平面上に立てられる底面部をもち、所定容量の飲料を収容可能な剛性容器からなる。このような容器本体２として、魔法瓶、ステンレス製の真空二重容器等の断熱容器を採用することができる。以下、容器本体２を水平面に立てたときを基準に、その水平面に対して垂直な方向を上下方向とし、ヒンジ軸５に沿った方向を左右方向とし、ヒンジ軸５に直角な水平直線の方向を前後方向とする。容器本体２の外周は、任意の水平断面において円形状にすることができる。容器本体２の最大外径は、１００ｍｍ以下に設定することができる。前記所定容量は、５００ｍｌ以下に設定することができる。これら外周形状、最大外径等は、容器本体２を片手で容易に把持し易くするためである。 The container body 2 includes a rigid container that has a bottom portion that can be erected on a horizontal plane and can store a predetermined volume of beverage. As such a container body 2, a heat insulating container such as a thermos bottle or a stainless steel vacuum double container can be adopted. Hereinafter, on the basis of when the container body 2 is set on a horizontal plane, a direction perpendicular to the horizontal plane is defined as an up-down direction, a direction along the hinge shaft 5 is defined as a left-right direction, and a direction of a horizontal straight line perpendicular to the hinge shaft 5 Is the front-rear direction. The outer periphery of the container body 2 can be circular in any horizontal cross section. The maximum outer diameter of the container body 2 can be set to 100 mm or less. The predetermined volume can be set to 500 ml or less. These outer peripheral shape, maximum outer diameter, and the like are for easily grasping the container body 2 with one hand.

栓カバー４は、容器本体２の上部に着脱可能になっている。これは、栓カバー４や容器本体２の洗浄や清掃を容易にするためである。その着脱構造として、ねじが採用されている。栓カバー４の内周に雌ねじが設けられている。容器本体２の外周に雄ねじが設けられている。栓カバー４を容器本体２に所定に螺合すると、栓カバー４が容器本体２に装着された状態となる。この装着状態では、図２に示すように、栓カバー４の流路口３が容器口１に連通している。また、この装着状態では、栓カバー４と容器口１の内周間が、栓カバー４に備わるパッキン８によって水密に密封される。 The stopper cover 4 can be attached to and detached from the upper part of the container body 2. This is for facilitating the cleaning and cleaning of the stopper cover 4 and the container body 2. A screw is employed as the attachment / detachment structure. A female screw is provided on the inner periphery of the stopper cover 4. A male screw is provided on the outer periphery of the container body 2. When the stopper cover 4 is screwed into the container body 2 in a predetermined manner, the stopper cover 4 is attached to the container body 2. In this mounted state, as shown in FIG. 2, the flow path port 3 of the plug cover 4 communicates with the container port 1. Further, in this mounted state, the inner periphery of the stopper cover 4 and the container opening 1 is sealed in a watertight manner by the packing 8 provided on the stopper cover 4.

蓋６は、流路口３を密封する栓９を有する。流路口３は、容器本体２内から飲料が流出する出口となる。流路口３は、栓９を密着させるシール面によって形成されている。栓９は、パッキンからなる。流路口３の流路断面が大きい場合、栓９は、蓋６の外殻表面とパッキンとで構成することができる。流路口３は、栓カバー４に設けられた空気逃し路１０の出入口を兼ねている。特許文献１のように複数の流路口を飲料流出用と空気抜き用に別々に設け、個々に栓で密封するように変更することも可能である。 The lid 6 has a plug 9 that seals the flow path port 3. The flow path port 3 serves as an outlet through which the beverage flows out from the container body 2. The flow path port 3 is formed by a seal surface to which the stopper 9 is brought into close contact. The stopper 9 is made of packing. When the channel cross section of the channel port 3 is large, the plug 9 can be constituted by the outer shell surface of the lid 6 and packing. The flow path port 3 also serves as an entrance / exit of an air escape path 10 provided in the plug cover 4. As in Patent Document 1, it is also possible to provide a plurality of flow passage openings separately for beverage outflow and air venting and to be individually sealed with a stopper.

栓カバー４は、環状壁１１を有する。環状壁１１は、容器本体２を傾けて流路口３から流出する飲料をその傾き側に導く流路を形成している。環状壁１１と蓋６は、流路口３を密封する栓９及び流路口３を覆い、外部から保護する。 The stopper cover 4 has an annular wall 11. The annular wall 11 forms a flow path for inclining the container body 2 to guide the beverage flowing out from the flow path port 3 to the inclined side. The annular wall 11 and the lid 6 cover the plug 9 and the channel port 3 for sealing the channel port 3 and protect them from the outside.

蓋６は、図２、図４、図５に示すように、栓カバー４の後部にヒンジ軸５を通した片開き式のものとなっている。ねじりコイルばね１２は、蓋６と栓カバー４間に介在している。ねじりコイルばね１２は、蓋６のヒンジ軸５回りの開回転によって、蓋６に与えられる開回転トルクを蓄勢する。 As shown in FIGS. 2, 4, and 5, the lid 6 is a single-open type in which a hinge shaft 5 is passed through the rear portion of the plug cover 4. The torsion coil spring 12 is interposed between the lid 6 and the plug cover 4. The torsion coil spring 12 accumulates the opening rotation torque applied to the lid 6 by the opening rotation of the lid 6 around the hinge shaft 5.

蓋６は、係止部材１４と、弾性部材１５とを有する。係止部材１４は、栓カバー４の受け部１３に引っ掛かって蓋６の開回転を阻止する。以下、係止部材１４が受け部１３と引っ掛かる位置は、単に「閉成位置」と呼ぶ。弾性部材１５は、閉成位置から外れた係止部材１４を自己の弾性反発力によって当該閉成位置まで押し戻す。 The lid 6 includes a locking member 14 and an elastic member 15. The locking member 14 is hooked on the receiving portion 13 of the plug cover 4 to prevent the lid 6 from opening. Hereinafter, the position where the locking member 14 is caught by the receiving portion 13 is simply referred to as a “closed position”. The elastic member 15 pushes the locking member 14 released from the closed position back to the closed position by its own elastic repulsive force.

蓋６は、回動可能な係止部材１４を一つだけ有する。蓋６の外殻は、一組の外殻部材１６、１７によって構成されている。係止部材１４は、外殻部材１６、１７によって上下に挟持されている。 The lid 6 has only one pivotable locking member 14. The outer shell of the lid 6 is constituted by a set of outer shell members 16 and 17. The locking member 14 is sandwiched up and down by the outer shell members 16 and 17.

弾性部材１５は、ねじりコイルばねからなる。 The elastic member 15 is composed of a torsion coil spring.

図２、図５、図６（ａ）、図７（ａ）、（ｂ）に示すように、係止部材１４と外殻部材１７の一方に突軸部１８が設けられ、他方に滑り軸受部１９が設けられている。突軸部１８は、滑り軸受部１９に嵌合する。この嵌合は、突軸部１８と滑り軸受部１９の一方に弾性部材１５のコイル部を嵌めた状態で行うことができる。その結果、突軸部１８と滑り軸受部１９は、係止部材１４の回動軸となり、かつコイル部をコイル径方向に支持する軸部２０になる。外殻部材１７に静止側トルク受け部２１が設けられている。係止部材１４に回転側トルク受け部２２が設けられている。静止側トルク受け部２１は、軸部２０にコイル部を通された弾性部材１５の片脚を受け、回転側トルク受け部２２は、弾性部材１５の残りの片脚を受ける。 As shown in FIGS. 2, 5, 6A, 7A, and 7B, a protruding shaft portion 18 is provided on one of the locking member 14 and the outer shell member 17, and a sliding bearing is provided on the other. A part 19 is provided. The projecting shaft portion 18 is fitted to the sliding bearing portion 19. This fitting can be performed in a state where the coil portion of the elastic member 15 is fitted to one of the projecting shaft portion 18 and the sliding bearing portion 19. As a result, the projecting shaft portion 18 and the sliding bearing portion 19 become the pivot shaft of the locking member 14 and the shaft portion 20 that supports the coil portion in the coil radial direction. The outer shell member 17 is provided with a stationary torque receiving portion 21. The locking member 14 is provided with a rotation side torque receiving portion 22. The stationary side torque receiving portion 21 receives one leg of the elastic member 15 having the coil portion passed through the shaft portion 20, and the rotating side torque receiving portion 22 receives the remaining one leg of the elastic member 15.

図３、図５、図８に示すように、係止部材１４に操作レバー２４が設けられている。上側の外殻部材１６の後側に切欠き２５が形成されている。操作レバー２４は、切欠き２５から蓋６の天面に露出している。容器本体２を把持する使用者は、その把持している手の人差し指を、閉じている蓋６の後側から操作レバー２４に掛け、その人差し指を、左右片側に動かして操作レバー２４を回すレバー操作が可能である。このレバー操作によって、図２に示す係止部材１４に軸部２０回りの回転トルクを与えることができる。 As shown in FIGS. 3, 5, and 8, the locking member 14 is provided with an operation lever 24. A notch 25 is formed on the rear side of the upper outer shell member 16. The operation lever 24 is exposed from the notch 25 to the top surface of the lid 6. A user who holds the container body 2 puts his / her index finger on the operation lever 24 from the rear side of the closed lid 6, moves the index finger to the left and right sides, and rotates the operation lever 24. Operation is possible. By this lever operation, a rotational torque around the shaft portion 20 can be applied to the locking member 14 shown in FIG.

図４、図６（ａ）〜（ｄ）に示すように、係止部材１４に爪部２６が設けられている。図４、図５、図７（ｂ）、（ｃ）に示すように、爪部２６は、外殻部材１７の開口２７から軸部２０の径方向に突出している。 As shown in FIGS. 4 and 6 (a) to 6 (d), a claw portion 26 is provided on the locking member 14. As shown in FIGS. 4, 5, 7 (b) and 7 (c), the claw portion 26 projects from the opening 27 of the outer shell member 17 in the radial direction of the shaft portion 20.

図４、図９（ａ）、（ｂ）に示すように、受け部１３は、環状壁１１の内周側に位置し、流路口３よりも高所で突出している。図１０（ｅ）、（ｆ）に示すように、爪部２６は、受け部１３と上下に引っ掛かる閉成位置にあるとき、図５に示すねじりコイルばね１２に抗して、蓋６のヒンジ軸５回りの開回転を阻止する。 As shown in FIGS. 4, 9 (a), and 9 (b), the receiving portion 13 is located on the inner peripheral side of the annular wall 11 and protrudes at a higher position than the flow path port 3. As shown in FIGS. 10 (e) and 10 (f), the claw 26 is hinged to the lid 6 against the torsion coil spring 12 shown in FIG. Open rotation around the shaft 5 is prevented.

爪部２６が受け部１３と非接触のとき、例えば、図４に示す蓋６が開き切ったときを考える。このとき、図１０（ａ）、（ｂ）に示すように、係止部材１４は、弾性部材１５によって、閉成位置に相当する軸部２０回りの向きに維持される。図１０（ａ）〜（ｄ）に示すように、爪部２６は、蓋６のヒンジ軸５回りの閉回転中に受け部１３の上面側と接触する。この接触によって、係止部材１４は軸部２０回りに回転トルクを与えられ、弾性部材１５に抗して閉成位置から外される。この後、爪部２６が受け部１３の上面側に接触しなくなる。こうなると、先の軸部２０回りの回転トルクで逆回転トルクを蓄勢している弾性部材１５によって、係止部材１４が押し戻される。その結果、図１０（ｅ）、（ｆ）に示すように、爪部２６が受け部１３に引っ掛かる閉成位置へ至る。この蓋６の閉回転の間に、栓９が流路口３を密封している状態になる。係止部材１４が閉成位置にある限り、蓋６の開回転は、その密封が維持される範囲に阻止される。 Consider the case where the claw portion 26 is not in contact with the receiving portion 13, for example, when the lid 6 shown in FIG. At this time, as shown in FIGS. 10A and 10B, the locking member 14 is maintained by the elastic member 15 in the direction around the shaft portion 20 corresponding to the closed position. As shown in FIGS. 10A to 10D, the claw portion 26 contacts the upper surface side of the receiving portion 13 during the closed rotation around the hinge shaft 5 of the lid 6. By this contact, the locking member 14 is given a rotational torque around the shaft portion 20 and is removed from the closed position against the elastic member 15. Thereafter, the claw portion 26 does not contact the upper surface side of the receiving portion 13. When this happens, the locking member 14 is pushed back by the elastic member 15 that accumulates the reverse rotational torque with the rotational torque around the shaft portion 20. As a result, as shown in FIGS. 10 (e) and 10 (f), the claw portion 26 reaches the closed position where it is caught by the receiving portion 13. During the closing rotation of the lid 6, the plug 9 seals the flow path port 3. As long as the locking member 14 is in the closed position, the opening of the lid 6 is prevented to the extent that its sealing is maintained.

係止部材１４、受け部１３及び弾性部材１５は、その栓９による密封の外側に位置しているので、容器本体２内の飲料で汚れる心配はない。 Since the locking member 14, the receiving portion 13, and the elastic member 15 are located outside the seal by the stopper 9, there is no fear that the beverage in the container body 2 gets dirty.

爪部２６及び受け部１３は、栓９の左右方向中央を通り、かつ前後方向に平行な仮想平面に関して面対称に引っ掛かるように設けられている。これは、流路口３を形成するシール面に対して、栓９を左右バランスよく密着させ、安定した密封効果を得るためである。 The claw part 26 and the receiving part 13 are provided so as to be hooked symmetrically with respect to a virtual plane passing through the center of the plug 9 in the left-right direction and parallel to the front-rear direction. This is in order to obtain a stable sealing effect by bringing the stopper 9 into close contact with the sealing surface forming the flow path port 3 in a balanced manner.

図１（ａ）〜（ｃ）に示すように、蓋６を開けるときは、係止部材１４が閉成位置から外れるまで回転する回転動作のみによって、全ての係止部材１４が全ての受け部１３と引っ掛かることのできない状態になる。すなわち、蓋６の開回転が可能な状態になる。使用者は、図１（ａ）に示すように、操作レバー２４を同図中に二点鎖線で描いたａ位置（図１０（ｂ）、（ｆ）の位置に相当）から右側へ同図中に一点鎖線で描いたｂ位置まで回すことによって、係止部材１４に前記回転動作を生じさせることができる。図中ｂ位置まで回すと、図５に示すねじりコイルばね１２が蓄勢している回転トルクによって、図１（ｂ）に示すように、蓋６が勝手に開かれようとする。栓９による密封の内側（つまり容器本体２内の飲料収容空間の内圧）が大気圧と同じ場合、蓋６は、勝手に開き切る。 As shown in FIGS. 1 (a) to 1 (c), when the lid 6 is opened, all the locking members 14 are all received by the rotating operation that rotates until the locking member 14 is removed from the closed position. It becomes a state which cannot be caught with 13. That is, the lid 6 can be opened and rotated. As shown in FIG. 1A, the user moves the operation lever 24 from the position a (corresponding to the positions shown in FIGS. 10B and 10F) to the right. The locking member 14 can be caused to rotate by rotating to a position b drawn with a one-dot chain line. When turned to the position b in the figure, the lid 6 tends to open freely as shown in FIG. 1 (b) by the rotational torque accumulated in the torsion coil spring 12 shown in FIG. When the inside of the seal by the stopper 9 (that is, the internal pressure of the beverage storage space in the container main body 2) is the same as the atmospheric pressure, the lid 6 opens without permission.

栓カバー４は、上昇面２８を有する。上昇面２８は、閉成位置から外れた係止部材１４と上下に接触する位置にある。図１（ａ）、図９、図１０（ｆ）に示す例では、上昇面２８が、軸部２０回りでの爪部２６の回転半径上に位置している。使用者は、図１（ａ）に示すように、操作レバー２４を図中ａ位置から右側へ図中ｂ位置まで回す操作をさらに継続し、図中に実線で描いたｃ位置まで回すことができる。図中ｂ位置から図中ｃ位置まで回す間に、爪部２６は、図１（ｂ）、（ｃ）に示すように、徐々に上昇面２８に乗り上げさせられる。栓９による密封の内側が大気圧に比して負圧のとき、蓋６の開回転が可能になっても蓋６の開回転が始まらないことが生じ得る。このとき、爪部２６が上昇面２８に乗り上げるに連れて、蓋６は、次第に自己の外殻部材を係止部材１４によって上方へ押される。その結果、蓋６に与えられる開回転トルクにより、蓋６が強制的に開回転させられる。栓９による密封が破れれば、容器本体２内の負圧が解消される。このため、蓋６の開回転が容易になる。操作レバー２４を回すことによる蓋６の強制回転量は、その密封を確実に破れることができれば十分である。 The plug cover 4 has a rising surface 28. The ascending surface 28 is in a position where it comes into contact with the locking member 14 deviated from the closed position vertically. In the example shown in FIGS. 1A, 9, and 10 F, the rising surface 28 is located on the rotation radius of the claw portion 26 around the shaft portion 20. As shown in FIG. 1A, the user can further continue the operation of turning the operating lever 24 from the position a to the right side in the figure to the position b in the figure, and to the position c drawn by a solid line in the figure. it can. While rotating from the position b in the figure to the position c in the figure, the claw portion 26 is gradually ridden on the rising surface 28 as shown in FIGS. When the inside of the seal by the stopper 9 is at a negative pressure as compared with the atmospheric pressure, the opening of the lid 6 may not start even if the opening of the lid 6 is enabled. At this time, as the claw portion 26 rides on the rising surface 28, the lid 6 gradually pushes its outer shell member upward by the locking member 14. As a result, the lid 6 is forcibly opened and rotated by the opening rotational torque applied to the lid 6. If the sealing by the stopper 9 is broken, the negative pressure in the container body 2 is eliminated. For this reason, the opening rotation of the lid 6 is facilitated. The amount of forced rotation of the lid 6 by turning the operation lever 24 is sufficient if the sealing can be reliably broken.

なお、図２に示すコップ７は、容器本体２に着脱可能になっている。容器本体２に装着されたコップ７は、栓カバー４及び蓋６に被さる。このため、この携帯飲料容器と鞄の中に一緒に入れた他物体が操作レバー２４に接触する不安はない。 Note that the cup 7 shown in FIG. 2 is detachable from the container body 2. The cup 7 attached to the container body 2 covers the stopper cover 4 and the lid 6. For this reason, there is no anxiety that other objects put together in the portable beverage container and the bag come into contact with the operation lever 24.

この携帯飲料容器は、図１（ａ）〜（ｃ）に示すように、係止部材１４の閉成位置からの回転動作を必須条件として、蓋６の開回転が可能になる。したがって、この携帯飲料容器が落下したとき、衝撃がどの一方向に作用しても、係止部材１４が衝撃を受ける一直線の向きと、係止部材１４が図１（ａ）中ａ位置の閉成位置から外れる同図中ｂ位置までの回転方向とが一致することはない。つまり、係止部材１４が閉成位置から完全に外れるまで衝撃で真直ぐに押され続けることは、起り得ない。このため、特許文献１のような一つの係止部材の直線運動のみで閉成位置から外れるものと比して、係止部材１４は、衝撃がどの一方向に作用した場合でも閉成位置から外れ難くなる。したがって、この携帯飲料容器は、落下した場合でも、蓋６が容易に開かないようにすることができる。 As shown in FIGS. 1A to 1C, the portable beverage container can open and rotate the lid 6 with the rotation operation from the closed position of the locking member 14 as an essential condition. Therefore, when this portable beverage container is dropped, no matter which direction the impact is applied, the locking member 14 is in a straight direction to receive the impact, and the locking member 14 is closed at the position a in FIG. The rotational direction from the formation position to the position b in the figure does not match. That is, it cannot occur that the locking member 14 continues to be pushed straight by an impact until it is completely removed from the closed position. For this reason, the locking member 14 can be moved from the closed position regardless of which direction the impact is applied, as compared with a case where the locking member 14 moves out of the closed position only by linear movement of one locking member as in Patent Document 1. It becomes difficult to come off. Therefore, even if this portable beverage container falls, the lid 6 can be prevented from being easily opened.

また、この携帯飲料容器は、操作レバー２４で一つの係止部材１４を回す回転動作のみのシンプルな構造でありながら、蓋６が容易に開かないようにすることができる。 Further, the portable beverage container has a simple structure with only a rotating operation of turning one locking member 14 with the operation lever 24, but the lid 6 can be prevented from being easily opened.

また、この携帯飲料容器は、操作レバー２４が蓋６の天面のヒンジ軸５側に位置しているため、容器本体２の上部外周を把持している手の人差し指で操作レバー２４を図中ａ位置から図中ｃ位置まで回転させることができる。なお、操作レバー２４を図中ａ位置から図中ｃ位置まで回しても１／４回転を超えない。 Further, in this portable beverage container, since the operation lever 24 is located on the hinge shaft 5 side of the top surface of the lid 6, the operation lever 24 is shown with the index finger of the hand holding the upper outer periphery of the container body 2 in the figure. It can be rotated from position a to position c in the figure. In addition, even if the operation lever 24 is rotated from the position a in the figure to the position c in the figure, it does not exceed 1/4 rotation.

以下、この発明の他の実施形態について説明する。なお、以下では、第１実施形態との相違点を述べるに留める。図１１は、第２実施形態を示す。第２実施形態の操作レバー２４は、蓋６の天面の左右片側（ヒンジ軸方向片側）に位置し、後側（ヒンジ軸側）へ回す操作で前記回転動作を生じさせるように設けられている。この場合、使用者が蓋６を開くとき、操作レバー２４を回す方向と、蓋６が開回転する方向が同側（後側）になる。このため、操作レバー２４を回す指が蓋６の開回転の邪魔にならず、スムーズに蓋６を開くことができる。 Hereinafter, other embodiments of the present invention will be described. Hereinafter, only differences from the first embodiment will be described. FIG. 11 shows a second embodiment. The operation lever 24 of the second embodiment is located on the left and right sides (one side in the hinge axis direction) of the top surface of the lid 6, and is provided so as to cause the rotation operation by turning to the rear side (the hinge shaft side). Yes. In this case, when the user opens the lid 6, the direction in which the operation lever 24 is rotated and the direction in which the lid 6 is opened and rotated are on the same side (rear side). For this reason, the finger turning the operation lever 24 does not interfere with the opening rotation of the lid 6 and can smoothly open the lid 6.

操作レバー以外の手段で係止部材の回転操作を行えるようにしてもよい。例えば、片手で容器本体を把持するのに不向きなサイズの携帯飲料容器の場合、操作レバーのような操作性を要求されない。このような場合に好適な変更例として、図１２に第３実施形態を示す。第３実施形態では、操作レバーに代えて、係止部材１４に摘み部３０が設けられている。蓋６の天面に露出している摘み部３０を指で摘むことができる。摘み部３０を回す操作によって係止部材１４を回すことが可能である。 The locking member may be rotated by means other than the operation lever. For example, in the case of a portable beverage container having a size unsuitable for holding the container body with one hand, the operability like the operation lever is not required. As a suitable modification example in such a case, a third embodiment is shown in FIG. In the third embodiment, a knob 30 is provided on the locking member 14 instead of the operation lever. The knob 30 exposed on the top surface of the lid 6 can be picked with a finger. The locking member 14 can be turned by an operation of turning the knob 30.

操作レバーに代わる別の手段として、スライダを採用することもできる。例えば、図１３（ａ）〜（ｄ）に示す第４実施形態のように、蓋６の天面に露出するスライダ４０を採用することができる。スライダ４０は、前後方向に往復直線運動を行える。スライダ４０は、係止部材１４と外殻部材１６とで挟持されている。係止部材１４は、カム面４１を有する。カム面４１は、スライダ４０が後方に動く動作を係止部材１４の回転動作に変換する。使用者がスライダ４０を後方まで引き切ると、係止部材１４は第１実施形態に相当する最大回転量に回転させられる。スライダ４０は、係止部材１４の閉成位置への復帰に伴って前方に復帰させられる。なお、スライダ４０の引き動作で係止部材１４を回転させるだけでなく、逆向きの動作にすることも可能である。例えば、図１３（ｅ）に一例を示すように、スライダ４０を係止部材１４の中心の方へ押す動作により、係止部材１４を回転させるようにすることも可能である。 A slider may be employed as another means instead of the operation lever. For example, a slider 40 exposed on the top surface of the lid 6 can be employed as in the fourth embodiment shown in FIGS. The slider 40 can reciprocate linearly in the front-rear direction. The slider 40 is sandwiched between the locking member 14 and the outer shell member 16. The locking member 14 has a cam surface 41. The cam surface 41 converts the movement of the slider 40 backward into the rotation of the locking member 14. When the user pulls the slider 40 backward, the locking member 14 is rotated to the maximum rotation amount corresponding to the first embodiment. The slider 40 is returned forward as the locking member 14 returns to the closed position. In addition, it is possible not only to rotate the locking member 14 by the pulling operation of the slider 40 but also to perform the reverse operation. For example, as shown in FIG. 13E, the locking member 14 can be rotated by an operation of pushing the slider 40 toward the center of the locking member 14.

操作レバーに代わる別の手段として、プッシュボタンを採用することもできる。例えば、図１４に示す第５実施形態のように、蓋６の天面に露出するプッシュボタン５０を採用することができる。プッシュボタン５０は、上下方向に往復直線運動を行える。プッシュボタン５０は、係止部材１４と外殻部材１６とで挟持されている。係止部材１４は、カム面５１を有する。カム面５１は、プッシュボタン５０が下方に動く動作を係止部材１４の回転動作に変換する。使用者がプッシュボタン５０を下方まで押し切ると、係止部材１４は第１実施形態に相当する最大回転量に回転させられる。プッシュボタン５０は、係止部材１４の閉成位置への復帰に伴って上死位置に復帰させられる。 As another means to replace the operation lever, a push button can be adopted. For example, a push button 50 exposed on the top surface of the lid 6 can be employed as in the fifth embodiment shown in FIG. The push button 50 can reciprocate linearly in the vertical direction. The push button 50 is sandwiched between the locking member 14 and the outer shell member 16. The locking member 14 has a cam surface 51. The cam surface 51 converts the movement of the push button 50 downward into the rotation of the locking member 14. When the user pushes the push button 50 down, the locking member 14 is rotated to the maximum rotation amount corresponding to the first embodiment. The push button 50 is returned to the top dead position as the locking member 14 returns to the closed position.

この発明の第６実施形態を図１５に基いて説明する。第６実施形態は、二つ以上の係止部材６０、６０を備える。係止部材６０、６０は、それぞれ左右方向に往復直線運動するようになっている。弾性部材１５は、コイルばねからなる。弾性部材１５は、両係止部材６０、６０の対向端部間に介在している。図中左側の係止部材６０は、右方向に閉成位置から外された後、左方向に押し戻されるようになっている。図中右側の係止部材６０は、左方向に閉成位置から外された後、右方向に押し戻されるようになっている。両係止部材６０、６０の操作部は、蓋６の天面に露出している。使用者は、両係止部材６０、６０の操作部を左右から摘むことで、全ての係止部材６０、６０を受け部１３、１３から外すことができる。 A sixth embodiment of the present invention will be described with reference to FIG. The sixth embodiment includes two or more locking members 60, 60. The locking members 60, 60 are adapted to reciprocate linearly in the left-right direction. The elastic member 15 is made of a coil spring. The elastic member 15 is interposed between the opposed end portions of the both locking members 60, 60. The locking member 60 on the left side in the drawing is pushed back to the left after being removed from the closed position in the right direction. The locking member 60 on the right side in the drawing is pushed back in the right direction after being removed from the closed position in the left direction. The operation portions of both the locking members 60 and 60 are exposed on the top surface of the lid 6. The user can remove all the locking members 60, 60 from the receiving portions 13, 13 by gripping the operation portions of both the locking members 60, 60 from the left and right.

第６実施形態では、複数の係止部材６０、６０がそれぞれ閉成位置から互いに異なる向きで外れる動作を必須条件として、蓋６の開回転が可能になる。このため、落下の衝撃がどの一方向に作用しても、どれか一つの係止部材６０、６０については、自己が衝撃を受ける向きと、自己が閉成位置から外れる方向とが一致することはない。図示例だと、係止部材６０、６０が互いに相反する方向に閉成位置から外れる。仮に衝撃が右から左方向に向って作用したとしても、外れ得るのは図中右側の係止部材６０だけであり、図中左側の係止部材６０が外れる心配はない。このように第６実施形態は、二つ以上の係止部材６０、６０が複数方向に動く動作を必須条件として、蓋６の開回転が可能になる。このため、衝撃がどの一方向に作用するとしても、少なくとも一つの係止部材６０が閉成位置から外れない。したがって、第６実施形態は、落下した場合、蓋６が容易に開かないようにすることができる。なお、上昇面２８は、係止部材６０、６０の左右方向の対向端部間に位置し、係止部材６０、６０の対向端部がそれぞれに乗り上げるようになっている。二つ以上の係止部材６０、６０を採用する場合、第６実施形態のように同一形状の係止部材６０に統一する必要はない。 In the sixth embodiment, the opening of the lid 6 can be performed on the condition that the plurality of locking members 60, 60 are disengaged from the closed position in different directions. For this reason, no matter which direction the impact of the drop is applied to, any one of the locking members 60, 60 must have the same direction in which the impact is received and the direction in which the self is removed from the closed position. There is no. In the illustrated example, the locking members 60, 60 are disengaged from the closed position in opposite directions. Even if the impact acts from the right to the left, only the locking member 60 on the right side in the figure can be removed, and there is no fear that the locking member 60 on the left side in the figure is released. As described above, in the sixth embodiment, the lid 6 can be opened and rotated by using an operation in which two or more locking members 60 and 60 move in a plurality of directions as an essential condition. For this reason, even if an impact acts in any one direction, at least one locking member 60 does not come off from the closed position. Therefore, 6th Embodiment can prevent the lid | cover 6 from opening easily, when falling. The ascending surface 28 is located between the opposing ends of the locking members 60, 60 in the left-right direction, and the opposing ends of the locking members 60, 60 ride on each other. When two or more locking members 60, 60 are employed, it is not necessary to unify the locking members 60 having the same shape as in the sixth embodiment.

この発明の第７実施形態を図１６に基いて説明する。第７実施形態は、二つの係止部材７０、７０を備える。係止部材７０、７０の円弧状部は、それぞれ外殻部材１７の円弧状溝部７１、７１に嵌っている。係止部材７０、７０は、それぞれ円弧状溝部７１、７１により、共通の上下方向軸線回りの回動方向に案内される。弾性部材１５は、コイルばねからなる。弾性部材１５は、両係止部材７０、７０の円周方向の対向端部間に介在している。図１６（ａ）、（ｄ）中で上側の係止部材７０は、右回転方向に閉成位置から外された後、左回転方向に押し戻されるようになっている。同図中で下側の係止部材７０は、左回転方向に閉成位置から外された後、右回転方向に押し戻されるようになっている。両係止部材７０、７０の操作部は、蓋６の天面に露出している。使用者は、両係止部材７０、７０の操作部を左右から摘むことで、全ての係止部材７０、７０を受け部（図示省略）から外すことができる。 A seventh embodiment of the present invention will be described with reference to FIG. The seventh embodiment includes two locking members 70, 70.

この発明の第８実施形態を図１７に基いて説明する。第８実施形態は、係止部材８０と、ロック部材８１とを備える。ロック部材８１は、係止部材８０を閉成位置に規制するためのものである。係止部材８０は、前後方向に往復直線運動するようになっている。弾性部材１５は、コイルばねからなる。弾性部材１５は、係止部材８０と外殻部材１７の前後方向の対向端部間に介在している。係止部材８０は、後方向に閉成位置から外された後、前方向に押し戻されるようになっている。係止部材８０に溝部８２が設けられている。溝部８２は、左右方向に向いている。ロック部材８１は、溝部８２に嵌っている。外殻部材１６の天面に切欠き部８３が形成されている。ロック部材８１は、左右方向から切欠き部８３に対して進退可能になっている。係止部材８０が閉成位置にあるとき、使用者は、ロック部材８１を左右方向に動かして、切欠き部８３の内側に出し入れする操作を行うことができる。ロック部材８１は、自己の左右片側で切欠き部８３の後壁と前後方向に係合し、同時に、これと反対の左右片側で係止部材８０の溝部８２と前後方向に係合することができる。この同時係合により、ロック部材８１は、係止部材８０を閉成位置に規制することができる。 An eighth embodiment of the present invention will be described with reference to FIG. The eighth embodiment includes a locking member 80 and a lock member 81. The lock member 81 is for restricting the locking member 80 to the closed position. The locking member 80 reciprocates linearly in the front-rear direction. The elastic member 15 is made of a coil spring. The elastic member 15 is interposed between opposing ends of the locking member 80 and the outer shell member 17 in the front-rear direction. The locking member 80 is pushed back in the forward direction after being removed from the closed position in the backward direction. A groove 82 is provided in the locking member 80. The groove portion 82 faces in the left-right direction. The lock member 81 is fitted in the groove 82. A notch 83 is formed on the top surface of the outer shell member 16. The lock member 81 can advance and retreat with respect to the notch 83 from the left-right direction. When the locking member 80 is in the closed position, the user can perform an operation of moving the lock member 81 in the left-right direction and taking it in and out of the notch 83. The locking member 81 can be engaged with the rear wall of the notch 83 on the left and right sides of the locking member 81 in the front-rear direction, and at the same time, can be engaged with the groove 82 of the locking member 80 on the left and right sides opposite thereto. it can. By this simultaneous engagement, the lock member 81 can restrict the locking member 80 to the closed position.

第８実施形態では、ロック部材８１が左右方向に切欠き部８３から外れる動作の後、係止部材８０が当該閉成位置から後方に外れる動作により、蓋６の開回転が可能になる。落下の衝撃が前後方向に作用してもロック部材８１の規制が解除される心配がない。このため、係止部材８０が閉成位置から外れる心配はない。また、衝撃が左右方向に作用してロック部材８１の規制が解除されたとしても、係止部材８０が閉成位置から後方に外れる心配はない。このように第８実施形態は、係止部材８０とロック部材８１が複数方向に動く動作を必須条件として、蓋６の開回転が可能になる。衝撃がどの一方向に作用しても、係止部材８０又はロック部材８１が衝撃を受ける向きと、規制を解除する方向又は閉成位置から外れる方向とが一致することはない。したがって、第８実施形態は、落下した場合でも、蓋６が容易に開かないようにすることができる。 In the eighth embodiment, the opening of the lid 6 is enabled by the operation in which the locking member 81 is released from the closed position to the rear after the operation in which the lock member 81 is released from the notch 83 in the left-right direction. Even if the impact of the drop acts in the front-rear direction, there is no concern that the restriction of the lock member 81 is released. For this reason, there is no fear that the locking member 80 is disengaged from the closed position. Even if the impact acts in the left-right direction and the restriction of the lock member 81 is released, there is no concern that the locking member 80 will be disengaged rearward from the closed position. As described above, in the eighth embodiment, the lid 6 can be opened and rotated by using an operation in which the locking member 80 and the lock member 81 move in a plurality of directions. Regardless of the direction in which the impact is applied, the direction in which the locking member 80 or the lock member 81 receives the impact does not match the direction in which the restriction is released or the direction in which the locking member 80 is released from the closed position. Therefore, the eighth embodiment can prevent the lid 6 from opening easily even if it falls.

この発明の第９実施形態を図１８に基いて説明する。第９実施形態は、係止部材１４とロック部材９１とを備える。ロック部材９１は、係止部材１４を閉成位置に規制するためのものである。係止部材１４には、ロック部材９１を通す長孔部９２が形成されている。外殻部材１６の天面には、鉤孔部９３が形成されている。鉤孔部９３は、前後方向に長い長孔部と、回転方向に沿った円弧孔部とからなる。係止部材１４が閉成位置にあるとき、長孔部９２と外殻部材１６の鉤孔部９３の長孔部が上下方向に一致する。外殻部材１６、１７は、長孔部９２、鉤孔部９３に通されたロック部材９１を係止部材１４と共に挟持する。ロック部材９１は、蓋６の天面に露出している。ロック部材９１の上端部は、鉤孔部９３から上方に突出している。ロック部材９１は、鉤孔部９３の円弧孔部の範囲内で、係止部材１４と一体に回転することができる。係止部材１４が閉成位置にあるとき、ロック部材９１は、長孔部９２の前端から後方へ動く動作は可能である。一方、このときのロック部材９１と鉤孔部９３の長孔部とが回転方向に係合可能なため、ロック部材９１と係止部材１４とが一体に回転することはできない。この係合により、ロック部材９１は、係止部材１４を閉成位置に規制することができる。ロック部材９１が、鉤孔部９３の円弧孔部に至るまで後方に動く動作によって前記規制が解除された状態になる。つまり、係止部材１４が閉成位置から外れる回転動作が可能な状態になる。使用者は、ロック部材９１を鉤孔部９３に沿って動かす操作を行うことにより、蓋６を開くことができる。 A ninth embodiment of the present invention will be described with reference to FIG. The ninth embodiment includes a locking member 14 and a lock member 91. The lock member 91 is for restricting the locking member 14 to the closed position. The locking member 14 is formed with a long hole portion 92 through which the lock member 91 is passed. A fist hole 93 is formed on the top surface of the outer shell member 16. The hole portion 93 includes a long hole portion that is long in the front-rear direction and an arc hole portion that extends in the rotation direction. When the locking member 14 is in the closed position, the long hole portion 92 and the long hole portion of the hole portion 93 of the outer shell member 16 coincide with each other in the vertical direction. The outer shell members 16 and 17 hold the lock member 91 passed through the long hole portion 92 and the fist hole portion 93 together with the locking member 14. The lock member 91 is exposed on the top surface of the lid 6. The upper end portion of the lock member 91 protrudes upward from the hole portion 93. The lock member 91 can rotate integrally with the locking member 14 within the range of the arc hole portion of the hole portion 93. When the locking member 14 is in the closed position, the lock member 91 can move backward from the front end of the long hole portion 92. On the other hand, since the lock member 91 and the elongated hole portion of the hole portion 93 can be engaged in the rotation direction at this time, the lock member 91 and the locking member 14 cannot rotate integrally. By this engagement, the lock member 91 can restrict the locking member 14 to the closed position. The restriction is released by an operation in which the lock member 91 moves rearward until reaching the arc hole portion of the hole portion 93. That is, the locking member 14 is in a state in which it can be rotated out of the closed position. The user can open the lid 6 by performing an operation of moving the lock member 91 along the fistula 93.

第９実施形態は、係止部材１４の回転動作という第１実施形態に相当する必須条件と、係止部材１４とロック部材９１が複数方向に動く動作という第８実施形態に相当する必須条件をも採用したものである。したがって、第９実施形態は、落下した場合でも、特に蓋６が容易に開かないようにすることができる。なお、長孔部９２の壁面には孔幅を狭めたクリック抵抗域を形成することが好ましい。これは、ロック部材９１が容易に後方へ動かないようにするためである。 The ninth embodiment has an indispensable condition corresponding to the first embodiment that is a rotation operation of the locking member 14 and an indispensable condition that corresponds to the eighth embodiment that is an operation in which the locking member 14 and the lock member 91 move in a plurality of directions. Is also adopted. Therefore, the ninth embodiment can prevent the lid 6 from being easily opened even when it is dropped. Note that it is preferable to form a click resistance region with a narrow hole width on the wall surface of the long hole portion 92. This is to prevent the lock member 91 from moving backward easily.
