Description

本発明は、ボトル本体の上端部片側を中心に開閉する片開き蓋を備えた片開きボトルに関し、詳しくは、片開き蓋の不用意な開放を防止できる片開きボトルに関する。 The present invention relates to a single-open bottle provided with a single-open lid that opens and closes around one side of the upper end portion of the bottle body, and particularly relates to a single-open bottle that can prevent inadvertent opening of the single-open lid.

片開きボトルは、片手持ちして片開き蓋を開くとそのまま直飲みできるように形成されており、不用意な蓋開きを防止するために片開き蓋を閉じ位置にロックし、片手持ちしている手の指でロックを解除して片開き蓋を開けられるようにしている。 The single-open bottle is formed so that you can directly drink it by holding it with one hand and opening the single-open lid. To prevent inadvertent opening of the lid, lock the single-open lid in the closed position and hold it with one hand. The finger can be unlocked with the finger of the hand and the single-open lid can be opened.

このような片開きボトルとしては、従来、ボトル本体の片開き蓋側の端部に揺動自在に設けられて片開き蓋に係合するロック爪を先端に有するロック部材と、このロック部材と同一の揺動軸に揺動自在に取り付けられた基材と、この基材の表面側に取り付けられて上下方向にスライド可能な操作部との３部材で構成されたロック機構を備えたものがある（例えば、特許文献１参照）。 As such a single-open bottle, conventionally, a lock member that is provided at the end of the bottle body on the single-open lid side so as to be swingable and has a lock claw that engages with the single-open lid, and the lock member What is provided with a lock mechanism composed of three members: a base material that is swingably attached to the same swinging shaft, and an operation unit that is attached to the surface side of the base material and is slidable in the vertical direction. Yes (for example, see Patent Document 1).

上記操作部は裏面に係止突起を有し、上記基材は上下方向に延在して貫通するスリットを有し、また、上記ボトル本体の内部には、操作部がスライド範囲の上端に位置するときに係止突起に係止される被係止部が設けられている。操作部がスライド範囲の上端に位置してロック位置にあるとき、操作部がボトル本体側に押圧されても、係止突起が被係止部に係止して、操作部のボトル本体側への移動が規制される。これにより、基部及びロック部材の揺動が規制され、ロック爪と片開き蓋との係合が保たれて、片開き蓋のロックが保持される。一方、操作部が下方にスライド操作されてスライド範囲の下端のロック解除操作位置にあるとき、操作部がボトル本体側に押圧されるに伴い、操作部の係止突起が被係止部に阻止されることなくボトル本体側に移動する。これにより、基部及びロック部材が揺動してロック爪と片開き蓋との係合が解除され、片開き蓋のロックが解除される。その結果、片開き蓋の開閉軸に設けられたバネによって片開き蓋が開き方向に付勢され、片開き蓋が開放されるようになっている。 The operation part has a locking projection on the back surface, the base material has a slit extending through in the vertical direction, and the operation part is located at the upper end of the slide range inside the bottle body. A locked portion that is locked to the locking projection when the locking is performed is provided. When the operation unit is located at the upper end of the slide range and is in the lock position, even if the operation unit is pressed toward the bottle body side, the locking projection is locked to the locked part and moves toward the bottle body side of the operation unit. Movement is restricted. As a result, the swinging of the base and the lock member is restricted, the engagement between the lock claw and the single-open lid is maintained, and the lock of the single-open lid is held. On the other hand, when the operating part is slid downward and is in the unlocking operation position at the lower end of the sliding range, the locking projection of the operating part is blocked by the locked part as the operating part is pressed toward the bottle body side. It moves to the bottle body side without being done. As a result, the base and the lock member are swung to disengage the lock claw and the single-open cover, and the single-open cover is unlocked. As a result, the single-opening lid is urged in the opening direction by a spring provided on the opening / closing shaft of the single-opening lid, so that the single-opening lid is opened.

このように、特許文献１の片開きボトルは、操作部が下方にスライド操作されてロック状態が解除され、引き続いて、操作部がボトル本体側に押圧されることにより、片開き蓋が開放する。操作部は、操作容易のためロック位置において十分に外方に突出しているが、ロック解除操作位置におけるのと同様な突出状態になっている。 As described above, in the single-open bottle of Patent Document 1, the operation unit is slid downward to release the locked state, and then the operation unit is pressed toward the bottle body, thereby opening the single-open lid. . The operation portion protrudes sufficiently outward at the lock position for easy operation, but is in the same protruding state as that at the lock release operation position.

また、他のロック機構を備えた従来の片開きボトルとしては、片開き蓋の回動端外面に設けられた係合片と、ボトル本体の口栓部材の外面に設けられ、中間部が軸部材で軸支されて口栓部材の内外方向に揺動可能に取り付けられたシーソー式のロックボタンと、口栓部材の外周壁にスライド可能に設けられたストッパとで構成されたロック機構を備えたものがある（例えば、特許文献２参照）。 In addition, as a conventional single-open bottle provided with another lock mechanism, an engagement piece provided on the outer surface of the rotating end of the single-open lid, and an outer surface of the cap member of the bottle body, the intermediate portion is a shaft. It has a lock mechanism composed of a seesaw-type lock button that is pivotally supported by a member and is swingably mounted in the inside and outside of the plug member, and a stopper that is slidably provided on the outer peripheral wall of the plug member. (See, for example, Patent Document 2).

上記ロックボタンは、片開き蓋の係合片が係合可能な係合溝が上端に形成されており、このロックボタンの内側面には、係合溝を片開き蓋の係止片と係合する方向に付勢するスプリングが配置されている。上記ストッパは上端にストッパ片を有し、このストッパがスライド範囲の上端であるロック位置にあるときに、ストッパ片がロックボタンの下端の裏面と口栓部材の外周壁との間に挿入されて、ロックボタンのロック解除方向への動きが規制される。一方、ストッパが下方にスライド操作され、スライド範囲の下端であるロック解除操作位置に達すると、ストッパ片がロックボタンの下端の裏面と口栓部材の外周壁との間から退去する。この後、ロックボタンの下部の表面を押圧することにより、ロックボタンが回動して上端が片開き蓋から遠ざかり、ロックボタンの係合溝と片開き蓋の係合片との係合が解除されて片開き蓋が開放可能となる。 The lock button has an engagement groove at the upper end that can be engaged with the engagement piece of the single-open lid, and the engagement groove is engaged with the locking piece of the single-open lid on the inner surface of the lock button. A spring that biases in the direction of mating is arranged. The stopper has a stopper piece at the upper end, and when the stopper is in the lock position, which is the upper end of the slide range, the stopper piece is inserted between the back surface of the lower end of the lock button and the outer peripheral wall of the plug member. The movement of the lock button in the unlocking direction is restricted. On the other hand, when the stopper is slid downward and reaches the unlocking operation position which is the lower end of the sliding range, the stopper piece is retracted from between the back surface of the lower end of the lock button and the outer peripheral wall of the plug member. After that, by pressing the lower surface of the lock button, the lock button rotates and the upper end moves away from the single-open lid, and the engagement between the lock groove of the lock button and the single-open lid engagement piece is released. Thus, the one-sided lid can be opened.

このように、特許文献２の片開きボトルは、ストッパ片が片開き蓋から遠ざかる方向にスライド操作されてロック状態が解除され、引き続いて、ストッパ片とは別体のロックボタンが押圧されることにより、片開き蓋が開放する。
特開２００６−１５８７２９号公報特開２００５−１９３９４４号公報 As described above, in the single-open bottle of Patent Document 2, the stopper piece is slid in the direction away from the single-open lid to release the locked state, and subsequently, the lock button separate from the stopper piece is pressed. Thus, the one-sided lid is opened.

しかしながら、特許文献１の片開きボトルは、操作部がロック解除操作位置にあるとき、この片開きボトルが転倒したり他のものに接触したりすると、外方に突出した操作部がボトル本体側に駆動されて、操作者の意図によらず片開き蓋が開放し、ボトル本体内の飲料の漏出を招くという問題がある。 However, in the single-open bottle of Patent Document 1, when the operation part is in the unlocking operation position, if the single-open bottle falls over or contacts another object, the operation part that protrudes outward is the bottle body side. However, the lid is opened regardless of the operator's intention, and the beverage in the bottle body leaks.

また、片開き蓋のロックを解除する際、操作部をスライド操作してスライド範囲の下端に達したとき、このスライド操作の際に働いてしまう押圧力によって操作部が押圧されて、操作者の意図によらず片開き蓋が開放するという問題がある。詳しくは、操作部は、基部及びロック部材の揺動軸から遠ざかる方向にスライド操作され、揺動アーム長が長い位置でスライド操作が終了するので、このスライド操作の終了時の操作力により、操作者の意図によらず操作部が押圧駆動されて片開き蓋が開放してしまう。 In addition, when unlocking the one-sided lid, when the operating unit is slid to reach the lower end of the sliding range, the operating unit is pressed by the pressing force that is applied during the sliding operation, and the operator's There is a problem that the single-opening lid opens without intention. Specifically, the operation unit is slid in a direction away from the swing shaft of the base and the lock member, and the slide operation is finished at a position where the swing arm length is long. Regardless of the person's intention, the operation unit is pressed and the one-sided lid is opened.

また、このロック機構は３つの部材で構成されて部品点数が多いので、片開きボトルの製造コストの上昇を招く虞がある。 Moreover, since this lock mechanism is comprised by three members and there are many number of parts, there exists a possibility of causing the raise of the manufacturing cost of a single-open bottle.

一方、特許文献２の片開きボトルは、２つの部材で構成されて部品点数が少ないものの、ストッパをロックボタンから遠ざかる方向にスライドさせてロック解除操作位置にした後、ロックボタンを押圧して片開き蓋を開放するので、ストッパとロックボタンとの互いに異なる部材を断続して操作する必要があり、操作性が悪いとう問題がある。 On the other hand, the single-open bottle of Patent Document 2 is composed of two members and has a small number of parts. However, after the stopper is slid away from the lock button to the unlocking operation position, the lock button is pressed and the piece is opened. Since the opening lid is opened, it is necessary to intermittently operate different members of the stopper and the lock button, and there is a problem that the operability is poor.

そこで、本発明は、少ない部品点数により、しかも、操作性を悪化することなく、転倒や他のものへの接触による片開き蓋の開放を防止できる片開きボトルを提供することを課題としている。また、操作者の意図しない片開き蓋の開放を防止できる片開きボトルを提供することを課題とする。 Then, this invention makes it a subject to provide the single-open bottle which can prevent the open of the single-open lid by a fall or contact with another thing by a small number of parts, and without deteriorating operability. It is another object of the present invention to provide a single-open bottle capable of preventing the single-open lid unintended by the operator.

上記課題を解決するため、本発明の１つの特徴の片開きボトルは、ボトル本体と、ボトル本体の上端部片側を中心に開閉する片開き蓋と、片開き蓋を閉じ位置にロックし、かつロックを解除できるようにしたロック機構とを備えた片開きボトルであって、上記ロック機構は、片開き蓋を閉じ位置にロックするロック部材と、ロック部材のロック状態をボトル本体側への押圧を受けても保持するロック位置とロック部材のロック状態をボトル本体側への押圧を受けて解除操作するロック解除操作位置との間で移動操作されるロック解除部材とを有し、上記ロック解除部材は、ロック位置における反ボトル本体側外方への突出量よりも、ロック解除操作位置における反ボトル本体側外方への突出量の方が小さいことを基本構成としている。 In order to solve the above problems, a single-open bottle according to one aspect of the present invention includes a bottle main body, a single-open lid that opens and closes around the upper end portion of the bottle main body, a single-open lid locked in a closed position, and A single-open bottle having a lock mechanism capable of releasing the lock, wherein the lock mechanism includes a lock member that locks the single-open lid in the closed position, and presses the lock state of the lock member toward the bottle body. A lock position that is held even when the lock is received and a lock release member that is operated to move between a lock release position that releases the lock state of the lock member in response to a pressure on the bottle body side, The member has a basic configuration in which the amount of protrusion toward the anti-bottle body side outward at the unlocking operation position is smaller than the amount of protrusion toward the anti-bottle body side outward at the lock position.

上記構成によれば、片開き蓋のロックを解除する際、ロック解除部材がロック位置からロック解除操作位置に移動操作され、このロック解除部材が設けられたロック部材がロック解除部材の応動によって駆動操作される。これにより、片開き蓋のロックが解除されて開放が可能となる。このように、ロック解除部材の移動操作に連続してロック部材の駆動操作を行って、片開き蓋を開放することができるので、操作性が良好な片開きボトルが得られる。 According to the above configuration, when unlocking the one-sided lid, the unlocking member is moved from the locking position to the unlocking operation position, and the locking member provided with the unlocking member is driven by the response of the unlocking member. Operated. Thereby, the lock | rock of a one side cover is cancelled | released and opening | release is attained. As described above, since the single-open lid can be opened by performing the drive operation of the lock member continuously after the movement operation of the lock release member, a single-open bottle with good operability can be obtained.

また、ロック解除部材がロック解除操作位置にある状態で転倒したり他のものに接触しても、ロック解除部材は、ロック位置における反ボトル本体側外方への突出量よりもロック解除操作位置における反ボトル本体側外方への突出量の方が小さいので、ロック解除部材がロック部材と共に駆動されることを防止できる。したがって、操作者の意図によらず片開き蓋が開放する不都合を防止できる。なお、操作者による片開き蓋のロック解除操作は、ロック解除の意図を持ってロック解除部材に操作力を集中させるように行われることから、ロック解除部材の外方への突出量が小さくても特に不便になることは無い。 In addition, even if the lock release member falls or contacts another object while it is in the unlock operation position, the lock release member is more in the unlock operation position than the amount of outward protrusion of the anti-bottle body side in the lock position. Since the amount of protrusion of the anti-bottle main body to the outside is smaller, it is possible to prevent the unlocking member from being driven together with the locking member. Therefore, it is possible to prevent the inconvenience that the single-open lid is opened regardless of the operator's intention. Note that the unlocking operation of the one-sided lid by the operator is performed so that the operating force is concentrated on the unlocking member with the intention of unlocking, so the amount of outward protrusion of the unlocking member is small. There is no particular inconvenience.

また、ロック解除部材とロック部材との２つの部材でロック機構を構成できるので、片開きボトルの部品点数を少なくできて製造コストの削減を図ることができる。 In addition, since the lock mechanism can be configured by two members of the lock release member and the lock member, the number of parts of the single-open bottle can be reduced and the manufacturing cost can be reduced.

また、本発明の１つの特徴の片開きボトルは、さらに、上記ロック解除部材が反ボトル本体側外方に突出する操作部を有し、このロック解除部材の操作部が、ロック位置における反ボトル本体側外方への突出量よりも、ロック解除操作位置における反ボトル本体側外方への突出量の方が小さい。 The single-open bottle according to one aspect of the present invention further includes an operation portion in which the unlocking member protrudes outward from the anti-bottle body side, and the operation portion of the unlocking member is the anti-bottle in the locked position. The amount of outward protrusion of the anti-bottle main body side at the unlocking operation position is smaller than the amount of outward protrusion of the main body side.

上記さらなる構成によれば、ロック解除部材がロック解除操作位置にあるとき、操作部はロック位置における反ボトル本体側外方への突出量よりも小さいので、片開きボトルが転倒したり他のものに接触して操作部が押圧されても、片開き蓋の開放を防止できて、操作者の意図しない誤開放を防止できる。 According to the above further configuration , when the unlocking member is in the unlocking operation position, the operation portion is smaller than the amount of outward protrusion of the anti-bottle main body side in the locking position, Even if the operation unit is pressed in contact with the contact, it is possible to prevent the one-sided lid from being opened and to prevent erroneous opening that is not intended by the operator.

また、本発明の１つの特徴の片開きボトルは、特に、上記操作部が、上記ロック解除部材の、ロック位置とロック解除操作位置との間の移動操作方向での端部にあって反ボトル本体側に突出している。 In addition, the single-open bottle according to one aspect of the present invention is particularly characterized in that the operation portion is located at an end portion of the unlocking member in the movement operation direction between the lock position and the unlock operation position. Projects to the main body.

一実施形態の片開きボトルは、上記ロック解除部材が、ロック部材の裏側に組み付けられている。 In the single-open bottle of one embodiment, the lock release member is assembled on the back side of the lock member.

一実施形態の片開きボトルは、上記ロック解除部材が、ロック部材の表面に対して移動方向に傾斜している。 In the one-sided bottle of one embodiment, the unlocking member is inclined in the moving direction with respect to the surface of the locking member.

上述のように、本発明の片開きボトルによれば、ロック解除部材の反ボトル本体側外方への突出量が、反ボトル本体側外方に突出する操作部を、上記ロック解除部材の、ロック位置とロック解除操作位置との間の移動操作方向での端部に有した操作条件を確保して、ロック位置におけるよりもロック解除操作位置における方が小さいので、ロック解除部材がロック解除操作位置にある状態で片開きボトルが転倒したり他のものに接触しても、ロック解除部材がロック部材と共に駆動されることを防止できて、操作者の意図によらず片開き蓋が開放する不都合を防止できる。 As described above, according to the single-open bottle of the present invention, the amount of protrusion of the unlocking member to the outside of the anti-bottle main body side is the operation part of the anti-bottle main body side of the projecting portion. Ensuring the operating conditions at the end in the moving operation direction between the lock position and the unlock operation position, the unlocking position is smaller at the unlocking operation position than at the locking position. Even when the single-opening bottle falls over or is in contact with other objects in the position, the unlocking member can be prevented from being driven together with the locking member, and the single-opening lid is opened regardless of the operator's intention. Inconvenience can be prevented.

以下、本発明の片開きボトルを図示の実施形態により詳細に説明する。 Hereinafter, the single bottle of the present invention will be described in detail with reference to the illustrated embodiments.

図１は、本発明の実施形態の片開きボトルを示す断面図である。この片開きボトルは、ステンレス製の内壁及び外壁の間に真空断熱空間２を有するボトル本体１と、このボトル本体１の口部１ａの外壁に形成された雄ねじ３に螺合する雌ねじを有し、シールパッキン９を介してボトル本体１に装着された合成樹脂製の肩部材５と、この肩部材５の背面側に回動軸６を介して回動自在に取り付けられた合成樹脂製の片開き蓋７と、この肩部材５の正面側に設けられ、片開き蓋７を閉じ位置にロック及びロック解除するように形成されたロック機構８とを備えている。 FIG. 1 is a cross-sectional view showing a single-open bottle according to an embodiment of the present invention. This single-open bottle has a bottle main body 1 having a vacuum heat insulating space 2 between an inner wall and an outer wall made of stainless steel, and a female screw that is screwed into a male screw 3 formed on the outer wall of the mouth 1a of the bottle main body 1. , A synthetic resin shoulder member 5 attached to the bottle body 1 via a seal packing 9, and a synthetic resin piece rotatably attached to the back side of the shoulder member 5 via a rotation shaft 6. An open lid 7 and a lock mechanism 8 provided on the front side of the shoulder member 5 and formed to lock and unlock the single open lid 7 in the closed position are provided.

上記ボトル本体１は、片手持ちできる程度にスリム化した胴部１ｂを有し、この胴部１ｂの上部は、口部１ａに装着された肩部材５の下端に隣接して胴部１ｂよりもやや小径の首部１ｃに形成されている。ボトル本体１の胴部１ｂや首部１ｃを片手持ちして、片手持ちしている手の指によるロック機構８の操作や、これに伴う片開き蓋７の開き操作や、片開き蓋７の開放の後に後述する飲み口１４による直飲み動作を行い易い形状になっている。 The bottle body 1 has a body portion 1b that is slimmed to the extent that it can be held by one hand, and the upper portion of the body portion 1b is adjacent to the lower end of the shoulder member 5 attached to the mouth portion 1a than the body portion 1b. It is formed on a slightly small neck 1c. Holding the body 1b and neck 1c of the bottle body 1 with one hand, the operation of the lock mechanism 8 with the finger of the hand held by one hand, the opening operation of the single-open lid 7 and the opening of the single-open lid 7 After this, the shape is such that a direct drinking operation by the drinking mouth 14 described later is easily performed.

肩部材５は、ボトル本体１の口部１ａを覆う概略円筒形状を有し、正面側にロック機構８を収容する膨出部が形成されている。この膨出部の最も突出した部分に、後述するロック部材１１及びロック解除部材１２の周りを取り囲む保護部材５１が一体形成されている。肩部材５の天面には、平面視において中心よりも正面側に偏った位置に、筒状の飲み口１４が突出して形成されている。 The shoulder member 5 has a substantially cylindrical shape that covers the mouth portion 1a of the bottle body 1, and a bulging portion that accommodates the lock mechanism 8 is formed on the front side. A protective member 51 surrounding the lock member 11 and the lock release member 12 described later is integrally formed at the most protruding portion of the bulging portion. On the top surface of the shoulder member 5, a cylindrical drinking mouth 14 is formed so as to protrude at a position deviated from the center to the front side in plan view.

片開き蓋７は、下端が開口した概ねドーム形状を有し、下端が肩部材５の側面の上端に嵌合するように形成されている。片開き蓋７の天井部の内側面には、片開き蓋７が閉じたときに飲み口１４の端面に密着するシールパッキン１６が設けられている。この片開き蓋７を肩部材５に取り付ける回動軸６まわりには、捻りバネ１３１が設けられて、片開き蓋７を開き方向に付勢している。また、片開き蓋７が閉じられたときに、飲み口１４に密着するシールパッキン１６の復元力によって片開き蓋７が開き方向に付勢されるようになっている。これにより、ボトル本体１を片手持ちしながら親指でロック機構８を解除すると片開き蓋７が回動軸６及びシールパッキン１６の付勢力によって容易に開き、そのままボトル本体１を傾けて肩部材５の飲み口１４から直飲みが可能になっている。 The one-sided lid 7 has a generally dome shape with an open lower end, and is formed so that the lower end is fitted to the upper end of the side surface of the shoulder member 5. A seal packing 16 is provided on the inner side surface of the ceiling portion of the one-sided lid 7 so as to be in close contact with the end surface of the drinking mouth 14 when the one-sided lid 7 is closed. A torsion spring 131 is provided around the rotation shaft 6 for attaching the one-sided lid 7 to the shoulder member 5 to urge the one-sided lid 7 in the opening direction. Further, when the single-opening lid 7 is closed, the single-opening lid 7 is urged in the opening direction by the restoring force of the seal packing 16 that is in close contact with the drinking mouth 14. Accordingly, when the lock mechanism 8 is released with the thumb while holding the bottle body 1 with one hand, the one-sided lid 7 is easily opened by the urging force of the rotating shaft 6 and the seal packing 16, and the bottle body 1 is tilted as it is and the shoulder member 5 is tilted. It is possible to drink directly from the mouth 14.

上記ロック機構８は、片開き蓋７の係合溝７１に係止して片開き蓋７を閉じ位置にロックするロック部材１１と、ロック部材１１によるロックを解除するロック解除部材１２とを備える。図１はロック解除部材１２がロック解除操作位置にある様子を示している。 The lock mechanism 8 includes a lock member 11 that is locked in the engagement groove 71 of the single-open lid 7 and locks the single-open lid 7 in the closed position, and an unlock member 12 that releases the lock by the lock member 11. . FIG. 1 shows a state in which the unlocking member 12 is in the unlocking operation position.

It is sectional drawing in the AA of (b). 4A is a front view of the unlocking member, FIG. 4B is a side view of the unlocking member, FIG. 4C is a rear view of the unlocking member, and FIG. These are sectional drawings in the BB line of Drawing 4 (a).

ロック機構８のロック部材１１は、図３（ａ）の正面図に示すように、半円状の上部と矩形の下部とが一体に形成されてなる。ロック部材１１の上部の裏側面にはロック爪１１１が形成されており、ロック部材１１の下部の厚み方向の中央には、ロック解除部材１２を案内する案内部１１２が形成されている。この案内部１１２は、表面側の表板部１１３と裏面側の裏板部１１４との間に形成され、この表板部１１３と裏板部１１４との間には、上部の幅方向中央から下方に延びる被挟部１１５が設けられている。この被挟部１１５の両側面には、図３（ｄ）の正断面図に示すように、上側のロック解除ノッチ１１５ａと下側のロックノッチ１１５ｂとが設けられている。この案内部１１２の表面側を画定する表板部１１３は、厚みが上側に向かって厚くなるように形成されている。これにより、案内部１１２は、側面視において、表板部１１３の表面に対して傾斜して形成されている。ロック部材１１の表面側の板部１１３の下端表面には、凹部１１ｂが形成されている。この凹部１１ｂは、ロック解除部材１２がロック解除操作位置にあるときに、操作部１２４と隣り合う位置に形成されている。ロック解除操作位置にあるロック解除部材１２の操作部１２４は、後に詳述するように、ロック部材１１の表面から突出する突出量が小さく形成していることから、上記凹部１１ｂを設けることによって指の係り代を大きくして、突出量が小さくても操作部１２４を容易に操作できるようにしている。ロック部材１１の上部の下側部分には、揺動軸が挿入される貫通穴１１ｃが幅方向に延在して形成されている。 As shown in the front view of FIG. 3A, the lock member 11 of the lock mechanism 8 is formed by integrally forming a semicircular upper portion and a rectangular lower portion. A lock claw 111 is formed on the back side surface of the upper portion of the lock member 11, and a guide portion 112 for guiding the lock release member 12 is formed in the center of the lower portion of the lock member 11 in the thickness direction. The guide portion 112 is formed between the front plate portion 113 on the front surface side and the back plate portion 114 on the back surface side, and between the front plate portion 113 and the back plate portion 114 from the center in the upper width direction. A sandwiched portion 115 extending downward is provided. As shown in the front sectional view of FIG. 3D, an upper lock notch 115a and a lower lock notch 115b are provided on both side surfaces of the sandwiched portion 115. The front plate portion 113 that defines the surface side of the guide portion 112 is formed so that the thickness increases toward the upper side. Thereby, the guide part 112 is inclined with respect to the surface of the front plate part 113 in a side view. A recess 11 b is formed on the lower end surface of the plate portion 113 on the surface side of the lock member 11. The recess 11b is formed at a position adjacent to the operation portion 124 when the unlocking member 12 is in the unlocking operation position. As will be described in detail later, the operation portion 124 of the unlocking member 12 at the unlocking operation position is formed with a small projection amount that projects from the surface of the lock member 11. Thus, the operating portion 124 can be easily operated even when the protrusion amount is small. A through hole 11c into which the swing shaft is inserted is formed in the lower part of the upper portion of the lock member 11 so as to extend in the width direction.

ロック機構８のロック解除部材１２は、図４（ａ）の正面図に示すように、正面視において矩形の下部板１２１を有し、この下部板１２１の上側には、互いに向き合う側に屈曲した鉤部１２２ａを先端に有する２つの挟棒１２２と、この挟棒１２２の両外側に配置されて裏面側に突出する２つのガイド板１２３が一体に形成されている。また、下部板１２１の下端には、表面側に突出する操作部１２４が設けられている。この操作部１２４の下端には、裏面側に屈曲した係止部１２４ａが形成されている。このロック解除部材１２は、図４（ｂ）の側面図及び図４（ｄ）の断面図に示すように、側面視において縦長の並行四辺形に形成されている。 As shown in the front view of FIG. 4A, the unlocking member 12 of the locking mechanism 8 has a rectangular lower plate 121 in a front view, and the upper side of the lower plate 121 is bent toward the sides facing each other. Two sandwiching rods 122 having a flange 122a at the front end and two guide plates 123 disposed on both outer sides of the sandwiching rod 122 and projecting to the back side are integrally formed. In addition, an operation portion 124 that protrudes to the front surface side is provided at the lower end of the lower plate 121. At the lower end of the operation portion 124, a locking portion 124a bent to the back side is formed. As shown in the side view of FIG. 4B and the cross-sectional view of FIG. 4D, the unlocking member 12 is formed in a vertically long parallelogram in a side view.

上記ロック解除部材１２は、図２（ａ）及び（ｂ）に示すように、ロック部材１１の案内部１１２内に上部が収容されて、ロック部材１１に摺動自在に取り付けられる。詳しくは、ロック部材１１の案内部１１２内にロック解除部材１２の上部が挿入され、このロック解除部材１２の挟棒１２２がロック部材１１の案内部１１２内の被挟部１１５の両側を挟むと共に、ロック解除部材１２のガイド板１２３の内側面がロック部材１１の裏板部１１４の両側面を挟んだ状態に組み付けられる。上記挟棒１２２は弾性を有し、２つの挟棒１２２で被挟部１１５を挟んだ状態で弾性変形をして、互いの鉤部１２２ａの先端から被挟部１１５の側面に押圧力を与えるようになっている。この押圧力により、鉤部１２２ａを各ノッチ１１５ａ，１１５ｂ内に押し込んで嵌合させるようになっている。ロック解除部材１２は、上部がロック部材１１の案内部１１２内をスライド可能になっており、ロック解除部材１２が上側のロック解除操作位置にあるときに、挟棒１２２の鉤部１２２ａが被挟部１１５のロック解除ノッチ１１５ａに嵌合する。また、ロック解除部材１２が下側のロック位置にあるときに、挟棒１２２の鉤部１２２ａが被挟部１１５のロックノッチ１１５ｂに嵌合する。これにより、ロック解除部材１２が、ロック部材１１に対して、ロック解除操作位置とロック位置に夫々保持されるようになっている。また、ロック解除部材１２は、ロック部材１１の表面に対して傾斜した案内部１１２に沿ってスライドする。これにより、操作部１２４が保護部材５１の表面から突出する突出量は、下端のロック位置における突出量よりも、上端のロック解除操作位置における突出量の方が小さくなる。さらに、操作部１２４がロック部材１１の表面から突出する突出量もまた、下端のロック位置における突出量よりも、上端のロック解除操作位置における突出量の方が小さくなる。 As shown in FIGS. 2A and 2B, the unlocking member 12 is housed in the guide portion 112 of the lock member 11 and is slidably attached to the lock member 11. Specifically, the upper part of the unlocking member 12 is inserted into the guide part 112 of the lock member 11, and the pin 122 of the unlocking member 12 sandwiches both sides of the sandwiched part 115 in the guide part 112 of the lock member 11. The inner surface of the guide plate 123 of the lock release member 12 is assembled with the both side surfaces of the back plate portion 114 of the lock member 11 sandwiched therebetween. The pin 122 is elastic and elastically deforms with the pinched portion 115 sandwiched between the two pinches 122 to apply a pressing force to the side surface of the pinched portion 115 from the tip of each brim 122a. It is like that. With this pressing force, the flange 122a is pushed into the notches 115a and 115b to be fitted. The upper part of the unlocking member 12 is slidable in the guide part 112 of the locking member 11, and when the unlocking member 12 is in the upper unlocking operation position, the hook part 122a of the sandwiching bar 122 is clamped. It fits into the unlocking notch 115a of the part 115. Further, when the unlocking member 12 is in the lower locking position, the flange 122 a of the pin 122 is fitted into the lock notch 115 b of the pinched portion 115. Thus, the lock release member 12 is held in the lock release operation position and the lock position with respect to the lock member 11, respectively. Further, the lock release member 12 slides along the guide portion 112 inclined with respect to the surface of the lock member 11. As a result, the protrusion amount at which the operation portion 124 protrudes from the surface of the protection member 51 is smaller in the protrusion amount at the unlock operation position at the upper end than at the lock position at the lower end. Furthermore, the amount of protrusion from which the operating portion 124 protrudes from the surface of the lock member 11 is also smaller in the amount of protrusion at the upper end unlocking operation position than the amount of protrusion at the lower end lock position.

上記ロック解除部材１２及びロック部材１１で構成されるロック機構８は、肩部材５の膨出部内に収容されている。図５（ａ）及び（ｂ）は、肩部材５の膨出部に設けられたロック機構８を正面側から見た様子を示す正面図である。肩部材５の膨出部には、正面視において概ね矩形状の収容室５２が肩部材５の上端縁に接するように形成されている。収容室５２内には、ロック部材１１が貫通穴１１ｃを貫通する揺動軸で揺動自在に取り付けられている。収容室５２の奥側壁には圧縮バネ５３の一端が固定されており、この圧縮バネ５３の先端がロック部材１１の裏側面に当接して、ロック爪１１１がボトル本体１側に向う方向にロック部材１１を圧縮バネ５３で付勢している。収容室５２内には、収容室５２の下側面に段部を形成してなる被係止部５４が設けられている。この被係止部５４の上端には、正面側に突出する突起５４ａが設けられている。この被係止部５４に、ロック位置にあるロック解除部材１２の係止部１２４ａが当接して、ロック解除部材１２及びロック部材１１の解除動作を規制するようになっている。上記被係止部５４の突起５４ａには、ロック解除部材１２の係止部１２４ａが係止することにより、不理解者によるボトル本体１側への無理な押圧操作を受けてもロック解除操作に至らないようになっている。すなわち、ロック位置にあるロック解除部材１２の操作部１２４は、通常の押圧操作ではロック解除部材１２の係止部１２４ａが被係止部５４に当接することによってロック解除操作はされないが、幼児等の不理解者によって無理に押圧されたり、意図せず他のものによって無理に押圧されたりすると、上方へのロック解除側の力がかかる場合がある。このような場合においても、ロック解除部材１２の係止部１２４ａが被係止部５４の突起５４ａに係止するので、ロック解除部材１２が意図せずロック解除操作位置に移動することを防止できる。 The lock mechanism 8 including the lock release member 12 and the lock member 11 is accommodated in the bulging portion of the shoulder member 5. 5A and 5B are front views showing a state in which the lock mechanism 8 provided at the bulging portion of the shoulder member 5 is viewed from the front side. In the bulged portion of the shoulder member 5, a substantially rectangular storage chamber 52 is formed so as to contact the upper end edge of the shoulder member 5 in a front view. In the storage chamber 52, the lock member 11 is swingably attached by a swing shaft that passes through the through hole 11c. One end of a compression spring 53 is fixed to the back side wall of the storage chamber 52, and the tip of the compression spring 53 comes into contact with the back side surface of the lock member 11 so that the lock claw 111 is locked in the direction toward the bottle body 1 side. The member 11 is biased by the compression spring 53. In the storage chamber 52, a locked portion 54 formed by forming a step portion on the lower surface of the storage chamber 52 is provided. At the upper end of the locked portion 54, a protrusion 54a protruding to the front side is provided. The locking portion 124a of the unlocking member 12 in the locked position comes into contact with the locked portion 54, and the releasing operation of the unlocking member 12 and the locking member 11 is restricted. The locking portion 124a of the unlocking member 12 is locked to the protrusion 54a of the locked portion 54, so that the unlocking operation can be performed even if an uncomfortable person receives an unreasonable pressing operation on the bottle body 1 side. It is not reached. That is, the operation part 124 of the unlocking member 12 in the locked position is not unlocked by the locking part 124a of the unlocking member 12 coming into contact with the locked part 54 in a normal pressing operation. If it is forcibly pressed by an ununderstood person or forcibly pressed by another person unintentionally, an upward unlocking force may be applied. Even in such a case, since the locking portion 124a of the unlocking member 12 is locked to the protrusion 54a of the locked portion 54, the unlocking member 12 can be prevented from unintentionally moving to the unlocking operation position. .

肩部材５の収容室５２内に取り付けられたロック部材１１は、上部が肩部材５の上端から突出している。肩部材５の上端に嵌合する片開き蓋７には、正面視において概ね半円形の蓋側収容室７２が片開き蓋７の下端縁に接して形成されており、この蓋側収容室７２内に係合溝７１が形成されている。片開き蓋７が閉じると、収容室５２の上端に蓋側収容室７２が連なり、蓋側収容室７２内にロック部材１１の上部が嵌合すると共に、蓋側収容室７２内の係合溝７１にロック部材１１のロック爪１１１が係合するようになっている。 The upper portion of the lock member 11 attached in the accommodation chamber 52 of the shoulder member 5 protrudes from the upper end of the shoulder member 5. The single-sided lid 7 fitted to the upper end of the shoulder member 5 is formed with a generally semicircular lid-side storage chamber 72 in contact with the lower end edge of the single-sided lid 7 in a front view. An engagement groove 71 is formed inside. When the single-open lid 7 is closed, the lid-side storage chamber 72 is connected to the upper end of the storage chamber 52, and the upper portion of the lock member 11 is fitted into the lid-side storage chamber 72, and the engagement groove in the lid-side storage chamber 72 is engaged. The lock claw 111 of the lock member 11 is engaged with 71.

以下、ロック機構による片開き蓋７のロック動作とロック解除動作について説明する。図１は、ロック解除部材１２がロック解除操作位置にあって片開き蓋７をロックした状態を示す一方、図２は、ロック解除部材１２がロック位置にあって片開き蓋７をロックした状態を示している。 Hereinafter, the locking operation and the unlocking operation of the one-sided lid 7 by the locking mechanism will be described. FIG. 1 shows a state in which the unlocking member 12 is in the unlocking operation position and the single-opening lid 7 is locked, while FIG. 2 shows a state in which the unlocking member 12 is in the locking position and the single-opening lid 7 is locked. Is shown.

まず、開放状態の片開き蓋７が、回動軸６回りに回動されて閉じ動作をして、片開き蓋７の下端が肩部材５の上端に嵌合する。この片開き蓋７の下端が肩部材５の上端に嵌合する直前、片開き蓋７の下端にロック部材１１のロック爪１１１の上端が接触する。このとき、ロック部材１１に取り付けられたロック解除部材１２がロック位置にある場合、ロック解除部材１２の下端の係止部１２４ａが肩部材５の収容室５２内の被係止部５４に係止して、ロック部材１１の揺動が規制される。この状態で片開き蓋７に閉じ側の力が操作者から与えられることにより、互いに接触したロック部材１１と片開き蓋７が弾性変形して片開き蓋７の下端がロック部材１１のロック爪１１１の上端を乗り越えて、片開き蓋７の係合溝７１内にロック部材１１のロック爪１１１が係合する。これにより、片開き蓋７が閉じた状態にロックされる。したがって、ロック解除部材１２をバネで付勢すること等によってロック位置に自動復帰するように構成しても、片開き蓋７を閉じたときにロック機構８が損傷するような問題は起きない。 First, the opened one-sided lid 7 is rotated around the pivot shaft 6 to perform a closing operation, and the lower end of the one-sided lid 7 is fitted to the upper end of the shoulder member 5. Immediately before the lower end of the single-open lid 7 is fitted to the upper end of the shoulder member 5, the upper end of the lock claw 111 of the lock member 11 contacts the lower end of the single-open lid 7. At this time, when the unlocking member 12 attached to the locking member 11 is in the locked position, the locking portion 124 a at the lower end of the unlocking member 12 is locked to the locked portion 54 in the storage chamber 52 of the shoulder member 5. Thus, the rocking of the lock member 11 is restricted. In this state, when the closing force is applied to the single-opening lid 7 by the operator, the lock member 11 and the single-opening lid 7 that are in contact with each other are elastically deformed, and the lower end of the single-opening lid 7 is the locking claw of the locking member 11. The lock claw 111 of the lock member 11 is engaged in the engagement groove 71 of the one-sided lid 7 over the upper end of 111. As a result, the single-open lid 7 is locked in a closed state. Therefore, even if the lock release member 12 is automatically returned to the lock position by urging the lock release member 12 with a spring or the like, there is no problem that the lock mechanism 8 is damaged when the one-sided lid 7 is closed.

なお、ロック部材１１は片開き蓋７よりも剛性が高く形成されていることが耐久性確保のために好ましい。また、閉じ動作の際に片開き蓋７の変形量がロック部材１１の変形量よりも大きくなるように、開き蓋７の係合溝７１の周囲から弾性変形しやすい肉厚関係等としておくのが好ましい。 The lock member 11 is preferably formed with higher rigidity than the single-open lid 7 in order to ensure durability. Further, a thickness relationship or the like that is easily elastically deformed from the periphery of the engaging groove 71 of the opening lid 7 is set so that the deformation amount of the single-opening lid 7 becomes larger than the deformation amount of the lock member 11 during the closing operation. Is preferred.

また、片開き蓋７を閉じる際、ロック解除部材１２はロック解除操作位置にあることが多く、この場合、片開き蓋７の下端がロック部材１１のロック爪１１１の上端に接触した後、ロック部材１１が圧縮バネ５３の付勢力に抗して外側に揺動退去して、片開き蓋７が更に回動して閉じ状態になる。 Further, when closing the single-opening lid 7, the unlocking member 12 is often in the unlocking operation position. In this case, after the lower end of the single-opening lid 7 comes into contact with the upper end of the lock claw 111 of the locking member 11, The member 11 swings and moves outward against the urging force of the compression spring 53, and the one-sided lid 7 is further rotated to be in a closed state.

片開き蓋７が閉じたとき、ロック解除部材１２をロック位置にすることにより、片開き蓋７の開放が防止される。すなわち、ロック解除部材１２の操作部１２４やロック部材１１の凹部１１ｂに操作者が押圧力を与えても、図２（ｂ）に示すように、ロック位置にあるロック解除部材１２の係止部１２４ａが肩部材５の収容室５２内の被係止部５４に係止して、ロック部材１１の揺動が規制される。この係止部１２４ａが被係止部５４に係止するとき、ロック部材１１のロック爪１１１は片開き蓋７の係合溝７１に係合したままである。したがって、操作部１２４が、誤操作や転倒や他のものに接触することによって押圧されても、片開き蓋７のロック状態が解除することが無い。また、操作部１２４が強く押圧されること等によってロック解除部材１２の係止部１２４ａが上側向きの力を受けても、この係止部１２４ａは被係止部５４の上端の突起５４ａに係止するので、係止部１２４ａが被係止部５４から脱落することを防止できる。したがって、片開き蓋７のロック状態を安定して保持できる。 When the single-opening lid 7 is closed, the unlocking member 12 is set to the locked position, thereby preventing the single-opening lid 7 from being opened. That is, even if the operator applies a pressing force to the operation portion 124 of the unlocking member 12 or the recess 11b of the locking member 11, the locking portion of the unlocking member 12 in the locked position as shown in FIG. 124a is locked to the locked portion 54 in the storage chamber 52 of the shoulder member 5, and the swinging of the lock member 11 is restricted. When the locking portion 124 a is locked to the locked portion 54, the lock claw 111 of the lock member 11 remains engaged with the engagement groove 71 of the one-sided lid 7. Therefore, even if the operation unit 124 is pressed by an erroneous operation, a fall, or contact with another object, the locked state of the one-sided lid 7 is not released. Further, even if the locking portion 124a of the unlocking member 12 receives an upward force due to the operation portion 124 being pressed strongly, the locking portion 124a is engaged with the protrusion 54a at the upper end of the locked portion 54. Since it stops, it can prevent that the latching | locking part 124a falls from the to-be-latched part 54. FIG. Therefore, the locked state of the single-open lid 7 can be stably maintained.

ロック状態の片開き蓋７を開くときは、操作部１２４が操作者によって上方に押し上げられ、ロック解除部材１２の挟棒１２２の鉤部１２２ａが、ロック部材１１の被挟部１１５のロック解除ノッチ１１５ａに係合する。これにより、図５（ｂ）に示すように、操作部１２４がロック部材１１の下端に近接した状態で保持される。続いて、操作部１２４が操作によってボトル本体１側に押圧されて、ロック解除部材１２及びロック部材１１が圧縮バネ５３の付勢力に抗して揺動軸回りに揺動する。これにより、ロック部材１１のロック爪１１１と片開き蓋７の係合溝７１との係合が解除され、捻りバネの付勢力によって片開き蓋７が駆動されて開放する。 When opening the one-sided lid 7 in the locked state, the operation portion 124 is pushed upward by the operator, and the flange portion 122a of the pin 122 of the lock release member 12 is unlocked notch of the pinched portion 115 of the lock member 11. 115a is engaged. Thereby, as shown in FIG. 5B, the operation unit 124 is held in a state of being close to the lower end of the lock member 11. Subsequently, the operation unit 124 is pressed toward the bottle body 1 by the operation, and the lock release member 12 and the lock member 11 are swung around the swing shaft against the urging force of the compression spring 53. As a result, the engagement between the lock claw 111 of the lock member 11 and the engagement groove 71 of the one-sided lid 7 is released, and the one-sided lid 7 is driven and released by the biasing force of the torsion spring.

本実施形態の片開きボトルは、ロック解除部材１２をロック位置からロック解除操作位置に移動させる場合、操作者の意図しない片開き蓋７の開放を防止できる。詳しくは、操作部１２４を操作してロック解除部材１２をロック位置からロック解除操作位置に移動させる際、操作部１２４を上方にスライドさせるので、ロック部材１１の揺動軸回りの揺動アーム長が短くなる。従来は、ロック部材の揺動アームが長くなる方向に操作部を操作していたので、スライド操作を行う力によってロック部材が押圧され、片開き蓋が意図せず開放していた。これに対して、本実施形態の片開きボトルは、揺動アーム長が短くなり、かつ、操作部１２４の突出量が小さくなる方向にロック解除部材１２をスライド操作してロック解除を行うので、ロック解除部材１２の操作部１２４に与える力でロック部材１１を揺動操作することを防止できる。したがって、単にロック解除部材１２によるロック解除のみを行うときに、意図せず片開き蓋７を開放してしまう不都合を防止できる。 When the unlocking member 12 is moved from the lock position to the unlocking operation position, the single-opening bottle of this embodiment can prevent the opening of the single-opening lid 7 not intended by the operator. Specifically, when operating the operation unit 124 to move the lock release member 12 from the lock position to the lock release operation position, the operation unit 124 is slid upward, so that the swing arm length around the swing shaft of the lock member 11 is increased. Becomes shorter. Conventionally, since the operation unit is operated in a direction in which the swing arm of the lock member becomes longer, the lock member is pressed by a force for performing a slide operation, and the one-sided lid is unintentionally opened. On the other hand, the single-open bottle of the present embodiment performs the unlocking by sliding the unlocking member 12 in the direction in which the swing arm length is shortened and the protruding amount of the operation unit 124 is reduced. It is possible to prevent the lock member 11 from being swung by the force applied to the operation portion 124 of the lock release member 12. Therefore, the inconvenience of unintentionally opening the one-sided lid 7 when only unlocking by the unlocking member 12 can be prevented.

このように、ロック解除のためにロック解除部材１２を片開き蓋７に近づく方向に駆動することは、従来のロック解除における操作と反対向きの操作であって、直感的な解除操作とは反対向きの操作である。したがって、本実施形態の片開きボトルは、ロック解除には、直感に反して、明確な意図をもってロック解除部材１２を片開き蓋７側に駆動操作する必要がある。しかも、ロック解除部材１２をロック部材１１の揺動アーム長が短くなるように駆動する。したがって、意図せずロック部材１１を揺動操作して片開き蓋７を意図せず開放させてしまう不都合を防止できるのである。 As described above, driving the unlocking member 12 in the direction approaching the one-sided lid 7 for unlocking is an operation opposite to the conventional unlocking operation, and is opposite to the intuitive unlocking operation. This is a direction operation. Therefore, it is necessary for the single-open bottle of this embodiment to drive the lock release member 12 to the single-open lid 7 side with a clear intention contrary to intuition for unlocking. Moreover, the lock release member 12 is driven so that the swing arm length of the lock member 11 is shortened. Therefore, it is possible to prevent the inconvenience of unintentionally opening the one-sided lid 7 by swinging the lock member 11.

さらに、本実施形態の片開きボトルは、ロック解除部材１２がロック解除操作位置にある場合においても、転倒等による意図しない片開き蓋７の開放を防止できる。すなわち、ロック解除部材１２がロック解除操作位置にあるとき、図１に示すように、保護部材５１の表面から操作部１２４がボトル本体側外方に突出する量が、ロック解除部材１２がロック位置にあるときよりも小さい。したがって、片開きボトルの転倒や、他のものへの接触により、突出した操作部１２４が押圧されても、ロック部材１１と片開き蓋７との係合が解除されることがない。したがって、片開き蓋７の意図しない開放が防止されて、ボトル本体１内の飲料等が漏出する不都合を防止できる。 Furthermore, even when the unlocking member 12 is in the unlocking operation position, the single-opening bottle of this embodiment can prevent the unintentional opening of the single-opening lid 7 due to overturning or the like. That is, when the unlocking member 12 is in the unlocking operation position, as shown in FIG. 1, the amount by which the operation unit 124 protrudes outward from the bottle body side from the surface of the protection member 51 is the unlocking member 12 in the locking position. Smaller than when it is. Therefore, even if the protruding operation part 124 is pressed due to the fall of the single-open bottle or contact with another, the engagement between the lock member 11 and the single-open lid 7 is not released. Therefore, the unintended opening of the single-open lid 7 is prevented, and the inconvenience that the beverage or the like in the bottle body 1 leaks can be prevented.

また、本実施形態の片開きボトルは、片開き蓋７のロック状態を容易に把握することができる。すなわち、ロック解除部材１２の操作部１２４よりも上側部分であって、ロック部材１１内に出没する部分の表面を、ロック部材１１と異なる色や、例えば蛍光色のような視認性の高い色に着色する。これにより、着色部分がロック時には外部に現れる一方、ロック解除時には現れないようにできる。これにより、着色部分が現れているか否かによって、片開き蓋７がロック状態であるか否かを容易に認識できる。 Moreover, the single-open bottle of this embodiment can grasp | ascertain the locked state of the single-open lid 7 easily. That is, the surface of the portion above the operation portion 124 of the unlocking member 12 that protrudes and appears in the locking member 11 has a color different from that of the locking member 11 or a highly visible color such as a fluorescent color. Color. This makes it possible to prevent the colored part from appearing when locked and not appearing when unlocked. Thereby, it can be easily recognized whether or not the one-sided lid 7 is in a locked state depending on whether or not a colored portion appears.

また、本実施形態では、ロック解除部材１２をロック部材１１に対して傾斜方向に案内することによって、操作部１２４の突出量をロック位置におけるよりもロック解除操作位置における方が小さく形成しているが、他の方法によって操作部１２４の保護部材５１の表面からの突出量を調節してもよい。例えば、保護部材５１の表面形状を、操作部１２４のロック解除操作位置に隣接する部分をロック位置に隣接する部分よりも突出させることにより、操作部１２４の突出量をロック位置におけるよりもロック解除操作位置における方が小さく形成することも可能である。このようなロック機構として、図７及び図８に示すようなものが考えられる。 Further, in the present embodiment, by guiding the lock release member 12 in the inclined direction with respect to the lock member 11, the protruding amount of the operation portion 124 is formed smaller at the lock release operation position than at the lock position. However, you may adjust the protrusion amount from the surface of the protection member 51 of the operation part 124 by another method. For example, by making the surface shape of the protection member 51 protrude from the portion adjacent to the unlocking operation position of the operation unit 124 more than the portion adjacent to the lock position, the protrusion amount of the operation unit 124 is unlocked more than at the lock position. It is also possible to form a smaller one at the operation position. As such a locking mechanism, the one shown in FIGS. 7 and 8 can be considered.

図７は、ロック解除部材３１２の脚部３１２ｄを、ロック部材３１１に形成したスライド窓３４１にスライド自在に嵌め合わせてロック機構３０８を構成している。肩部材３０５側には、脚部３１２ｄが係止するストッパ３２４を設けている。ロック解除部材３１２は、操作者の指が操作部３１２ａに掛けられて、実線のロック位置から矢印Ａの方向にスライドされて破線のロック解除操作位置に操作され、さらに、ロック解除操作位置から矢印Ｂの方向に押圧されて片開き蓋３０７のロック解除に至る。ロック解除部材３１２のロック位置では、脚部３１２ｄがストッパ３２４の端面に係止することによってロック解除操作が阻止される。 In FIG. 7, the locking mechanism 308 is configured by fitting the leg portion 312 d of the unlocking member 312 to the sliding window 341 formed in the locking member 311 so as to be slidable. On the shoulder member 305 side, a stopper 324 for locking the leg 312d is provided. The unlocking member 312 is slid in the direction of the arrow A from the solid line lock position when the operator's finger is hung on the operation unit 312a, and is operated to the unlocking operation position of the broken line. When pressed in the direction B, the one-sided lid 307 is unlocked. At the locked position of the unlocking member 312, the unlocking operation is prevented by the leg portion 312 d being engaged with the end face of the stopper 324.

このロック機構３０８は、保護部材３５１の表面の形状を、ロック位置にあるロック解除部材３１２の操作部３１２ａの部分よりも、ロック解除操作位置にあるロック解除部材３１２の操作部３１２ａの部分の方が張り出した形状にしている。これにより、保護部材３５１の表面から操作部３１２ａが突出する量について、ロック位置における突出量よりも、ロック解除操作位置における突出量が小さくなるようにしている。これにより、ロック解除操作位置にあるロック解除部材３１２の操作部３１２ａが、片開きボトルの転倒や他のものの接触等によって押圧されて操作者が意図しない片開き蓋３０７の開放を防止できる。なお、図７において、３４２はロック解除部材３１２とロック部材３１１との間に設けられ、ロック解除操作から開放されたロック解除部材３１２を初期位置に戻す引っ張りバネであり、３１１ａはロック部材３１１の係合部であり、３０７ｂは片開き蓋３０７の被係合部であり、３２１はロック部材３１１が片開き蓋３０７と係合する側にロック部材３１１を付勢する圧縮バネであり、３２３はロック部材３１１の揺動軸である。 The lock mechanism 308 is configured so that the shape of the surface of the protection member 351 is closer to the operation portion 312a of the unlocking member 312 in the unlocking operation position than to the operation portion 312a of the unlocking member 312 in the locking position. Has a protruding shape. Thereby, the amount of protrusion at the unlocking operation position is smaller than the amount of protrusion at the lock position with respect to the amount of protrusion of the operation portion 312a from the surface of the protection member 351. Thereby, the operation part 312a of the unlocking member 312 in the unlocking operation position can be prevented from being opened by the operator when the single-opening lid 307 is not intended by being pressed by the fall of the single-opening bottle or the contact of other things. In FIG. 7, 342 is a tension spring provided between the unlocking member 312 and the locking member 311, and returns the unlocking member 312 released from the unlocking operation to the initial position, and 311 a is the locking member 311. Reference numeral 307b denotes an engaged portion of the single-open lid 307, reference numeral 321 denotes a compression spring that biases the lock member 311 toward the side where the lock member 311 engages the single-open lid 307, and reference numeral 323 denotes This is a rocking shaft of the lock member 311.

一方、図８は、ロック解除部材４１２の左右両側の面に突設した角軸４１２ｂを、肩部材４０５側に形成された鉤型のガイド溝４２２にスライド自在に嵌め合わせてロック機構４０８を構成している。ガイド溝４２２の縦方向部分の奥側の面が、角軸４１２ｂが係止するストッパ面４２４である。ロック解除部材４１２は、操作者の指が操作部４１２ａに掛けられて、実線のロック位置から矢印Ａの方向にスライドされて破線のロック解除操作位置に操作され、さらに、ロック解除操作位置から矢印Ｂの方向に押圧されて片開き蓋４０７のロック解除に至る。ロック解除部材４１２のロック位置では、角軸４１２ｂがストッパ面４２４に係止することによってロック解除操作が阻止される。 On the other hand, FIG. 8 shows that the lock mechanism 408 is configured by slidably fitting the square shafts 412b projecting on both the left and right surfaces of the lock release member 412 into the hook-shaped guide groove 422 formed on the shoulder member 405 side. doing. The back surface of the longitudinal portion of the guide groove 422 is a stopper surface 424 that is engaged with the square shaft 412b. The unlocking member 412 is slid in the direction of arrow A from the locked position of the solid line by the operator's finger being hung on the operation unit 412a, and is operated to the unlocking operation position of the broken line. When pressed in the direction B, the one-sided lid 407 is unlocked. At the locked position of the unlocking member 412, the unlocking operation is prevented by the square shaft 412b being engaged with the stopper surface 424.

このロック機構４０８は、保護部材４５１の表面の形状を、ロック位置にあるロック解除部材４１２の操作部４１２ａの部分よりも、ロック解除操作位置にあるロック解除部材４１２の操作部４１２ａの部分の方が張り出した形状にしている。これにより、保護部材４５１の表面から操作部４１２ａが突出する量について、ロック位置における突出量よりも、ロック解除操作位置における突出量が小さくなるようにしている。これにより、ロック解除操作位置にあるロック解除部材４１２の操作部４１２ａが、片開きボトルの転倒や他のものの接触等によって押圧されて操作者が意図しない片開き蓋４０７の開放を防止できる。なお、図８において、４５２はロック解除部材４１２と肩部材４０５の収容室の底部との間に設けられ、ロック解除操作から開放されたロック解除部材４１２を初期位置に戻す圧縮バネであり、４１１ａはロック部材の係合部であり、４０７ｂは片開き蓋４０７の被係合部であり、４２１はロック部材４１１が片開き蓋４０７と係合する側にロック部材４１１を付勢する圧縮バネであり、４２３はロック部材４１１の揺動軸である。 The lock mechanism 408 is configured so that the surface shape of the protective member 451 is closer to the operation portion 412a of the unlocking member 412 at the unlocking operation position than to the operation portion 412a of the unlocking member 412 at the locking position. Has a protruding shape. As a result, the amount of protrusion at the unlocking operation position is smaller than the amount of protrusion at the lock position with respect to the amount of protrusion of the operation portion 412a from the surface of the protection member 451. Thereby, the operation part 412a of the unlocking member 412 at the unlocking operation position can be prevented from being opened by the operator when the single-opening lid 407 is unintentionally pressed by the fall of the single-opening bottle or the contact of another object. In FIG. 8, 452 is a compression spring provided between the unlocking member 412 and the bottom of the storage chamber of the shoulder member 405, and returns the unlocking member 412 released from the unlocking operation to the initial position. Is an engaging portion of the lock member, 407 b is an engaged portion of the single-open lid 407, and 421 is a compression spring that urges the lock member 411 toward the side where the lock member 411 engages with the single-open lid 407. 423 is a rocking shaft of the lock member 411.

ところで、本実施形態の片開きボトルは、ボトル本体１内に低温の飲料が収容されたとき、効果的に保冷を行うと共に、結露水の発生を防止するように構成されている。図６（ａ）は、肩部材５の内部をボトル本体１側から見た様子を示す底面図であり、図６（ｂ）は、肩部材５に取り付けられる内蓋５６を示す３面図である。この内蓋５６は、図１及び図６（ａ）に示すように、肩部材５の天面の内側に、飲み口１４よりも背面側の領域に亘って取り付けられている。内蓋５６の外縁から僅かに内側の位置に、この内蓋５６の外縁に沿う凸条５６ａが設けられている。肩部材５の天面の内側には、内蓋５６の輪郭と相似形の嵌合凹部５ａが形成されており、この嵌合凹部５ａに内蓋５６の凸条５６ａを嵌合し、この内蓋５６の縁を嵌合凹部５ａの内側面に超音波溶接で固定している。これにより、肩部材５の天面の嵌合凹部５ａと内蓋５６との間に、密封された空気層を形成している。 By the way, the single-open bottle of this embodiment is comprised so that when a low temperature drink is accommodated in the bottle main body 1, it cools effectively and prevents generation | occurrence | production of condensed water. FIG. 6A is a bottom view showing the inside of the shoulder member 5 as viewed from the bottle body 1 side, and FIG. 6B is a three-side view showing the inner lid 56 attached to the shoulder member 5. is there. As shown in FIGS. 1 and 6A, the inner lid 56 is attached to the inner side of the top surface of the shoulder member 5 over a region on the back side of the drinking mouth 14. A ridge 56 a along the outer edge of the inner lid 56 is provided at a position slightly inside from the outer edge of the inner lid 56. A fitting recess 5a similar to the contour of the inner lid 56 is formed inside the top surface of the shoulder member 5, and the protrusion 56a of the inner lid 56 is fitted into the fitting recess 5a. The edge of the lid | cover 56 is being fixed to the inner surface of the fitting recessed part 5a by ultrasonic welding. Thus, a sealed air layer is formed between the fitting recess 5 a on the top surface of the shoulder member 5 and the inner lid 56.

従来の片開きボトルでは、図９に示すように、ボトル本体１０１の口部１０１ａに樹脂製の飲み口部材１０２を取り付け、この飲み口部材１０２の下部の外側を囲むと共に飲み口１０２ａを上面から突出させる樹脂製の肩部材１０５を、ボトル本体１０１の上部に取り付けている。この肩部材１０５の天面に、飲み口１０２ａを覆う片開き蓋１０７を軸着している。肩部材１０５は、ボトル本体１０１の上部に嵌合された樹脂製の環状縁部材１０８に螺着されているのみであるので、飲み口部材１０２の表面に結露した水が、肩部材１０５と環状縁部材１０８との螺合部を通過して外部に漏出するという不都合が生じていた。 In the conventional single-open bottle, as shown in FIG. 9, a resin drinking mouth member 102 is attached to the mouth portion 101a of the bottle body 101, and the outside of the lower portion of the drinking mouth member 102 is surrounded and the drinking mouth 102a is viewed from above. A resin shoulder member 105 to be protruded is attached to the upper portion of the bottle body 101. On the top surface of the shoulder member 105, a one-sided lid 107 that covers the drinking mouth 102a is pivotally attached. Since the shoulder member 105 is only screwed to the resin-made annular edge member 108 fitted to the upper part of the bottle main body 101, water condensed on the surface of the drinking mouth member 102 is annularly connected to the shoulder member 105. There has been a problem in that it leaks to the outside through the threaded portion with the edge member 108.

これに対して、本実施形態の片開きボトルは、肩部材５の嵌合凹部５ａと内蓋５６との間に空気層を形成しているので、ボトル本体１内に低温飲料を収容しても、上記空気層の断熱効果によって肩部材５の表面に結露が生じることを防止できる。また、この空気層は、肩部材５の嵌合凹部５ａに嵌合した内蓋５６を超音波溶接で固定して形成しているので、安定して密封状態を保持することができる。したがって、長期にわたって安定して結露防止効果を奏することができる。また、空気層内への水等の浸入を防止できるので、侵入した水等を拭き取る手間が不要である。 On the other hand, since the single-open bottle of this embodiment forms the air layer between the fitting recessed part 5a of the shoulder member 5, and the inner cover 56, the low temperature drink is accommodated in the bottle main body 1. Moreover, it can prevent that dew condensation arises on the surface of the shoulder member 5 by the heat insulation effect of the said air layer. Moreover, since this air layer is formed by fixing the inner lid 56 fitted in the fitting recess 5a of the shoulder member 5 by ultrasonic welding, it is possible to stably maintain a sealed state. Therefore, the effect of preventing condensation can be stably achieved over a long period of time. Further, since it is possible to prevent water and the like from entering the air layer, there is no need to wipe off the invading water.
