Abstract
Description
本発明は、ボトル体の口部に装着されて内容液を直飲みできるようにするボトル栓と、これを用いた片開きボトルに関するものである。 The present invention relates to a bottle stopper that is attached to the mouth of a bottle body so that the content liquid can be directly taken and a single-open bottle using the bottle stopper.
このようなボトル栓や片開きボトルは既に知られており(例えば、特許文献1参照。)、ボトル体にボトル栓を装着したボトル本体と、ボトル栓にヒンジ連結した片開き蓋とを持ち、ボトル本体を片手持ちして片開き蓋を開くとそのまま飲み口から直飲みできようになっている。飲み口は直飲みしやすいように、特許文献1に開示されているようなボトル栓上端の前部寄りに細く立ち上がるように設けられるのが一般的であり、多くは前傾している。 Such bottle stoppers and single-open bottles are already known (for example, see Patent Document 1), have a bottle body with a bottle stopper attached to the bottle body, and a single-open lid hinged to the bottle stopper, If you hold the bottle body with one hand and open the one-sided lid, you can drink directly from the mouth. The drinking mouth is generally provided so as to be thinly raised near the front part of the upper end of the bottle stopper as disclosed in Patent Document 1 so that it can be easily taken directly, and many are inclined forward.
しかし、特許文献1に記載のような細く立ち上がる飲み口は、吸い飲みできるにもかかわらず、吸い飲みするとボトル体内への吸気ができないために内容液の注出がスムーズでない。スムーズな連続注出状態を得るには、飲み口の後部側に吸気隙間を残すように飲み口に口を付ける必要がある。このため、飲みにくく慣れが必要になる不便がある。また、急いだり、歩行など動きながらの直飲みの場合細く立ち上がる飲み口一杯に内容液を注出してしまって溢れ出たり、吸気ができなくなったりすることも生じやすい問題がある。 However, although the mouth which stands up thinly as described in Patent Document 1 can suck and drink, if the bottle is sucked and swallowed, the bottle body cannot be sucked, so that the content liquid is not smoothly poured out. In order to obtain a smooth continuous dispensing state, it is necessary to attach a mouth to the drinking mouth so as to leave an intake gap on the rear side of the drinking mouth. For this reason, there is an inconvenience that is difficult to drink and requires familiarity. In addition, when drinking directly while moving, such as in a hurry or walking, there is a problem that the content liquid is poured out into the full drinking mouth and overflows, or intake becomes impossible.
そこで、本発明者は、この種片開きボトルのボトル栓の改良につき、試行錯誤しながら開発を進め、飲み口を大きくしてその周方向一部への口付けにて容易に直飲みし、かつ、飲み口への内容液の注出の流れを適度に制限して注出状態を容易に失敗なく調整できるボトル栓を実現した。 Therefore, the present inventor has proceeded with development through trial and error to improve the bottle stopper of this kind of single-open bottle, and has a large drinking mouth and can be directly and easily swallowed, and The bottle stopper that can adjust the pouring state easily and without failure by moderately restricting the pouring flow of the content liquid into the drinking mouth has been realized.
本発明はそのような開発の基に、注出状態の容易で失敗のない調節を伴い直飲みしやすくできるボトル栓とこれを用いた片開きボトルを提供することを課題とする。 Based on such development, an object of the present invention is to provide a bottle stopper that can be easily swallowed with easy adjustment of the pouring state without failure and a single-open bottle using the bottle stopper.
上記課題を解決するため、本発明のボトル栓は、ボトル体の上端に装着される栓体を有し、この栓体にボトル体内に通じる基部通路と、この基部通路に注出口を介して通じた直飲みできる飲み口とを設けたことを基本構成とする。 In order to solve the above-mentioned problems, the bottle stopper of the present invention has a stopper attached to the upper end of the bottle body, a base passage that leads to the inside of the bottle through the stopper, and a base passage that leads to the base passage through a spout. The basic structure is to have a drinking mouth that can be directly drinkable.
このような構成によれば、ボトル体から流出してくる内容液を基部通路から注出口を通じ飲み口へのスムーズな注出状態を得、飲み口への内容液の注出状態や注出量を確認しながらの過不足ない思い通りの注出調節の基に容易に飲めるようにする。 According to such a configuration, the content liquid flowing out from the bottle body is smoothly poured out from the base passage through the spout to the drinking outlet, and the state and amount of the liquid being dispensed into the drinking outlet are obtained. Make it easy to drink on the basis of the dispensing control as you wish.
本発明は、基本構成に加え、栓体は、ボトル体の口部外側に装着される外栓部と、この外栓部からボトル体の口部内側に入って前記基部通路、注出口および飲み口を形成する中栓部とを有し、中栓部は、ボトル体の口部内側に沿う外筒と、前記基部通路、注出口および飲み口を有して前記外筒に下方から取り外せるように回り止め状態に嵌め合わされて相互間に空間を形成した内筒と、の組み合わせとしたことを特徴とする。 In the present invention, in addition to the basic configuration, the plug body includes an outer plug portion that is attached to the outside of the mouth portion of the bottle body, and the base passage, the spout, and the drinking portion that enter the inside of the mouth portion of the bottle body from the outer plug portion. An inner plug part that forms a mouth, and the inner plug part has an outer cylinder along the inner side of the mouth part of the bottle body, the base passage, a spout, and a drinking mouth so that the outer cylinder can be removed from below. And an inner cylinder that is fitted in a non-rotating state to form a space between them.
このような構成により、さらに、ボトル栓が外栓部でボトル体の口部外側に装着されてボトル体の口部外回りを外装して、しかも、中栓部でボトル体の側では得にくい前記基部通路、注出口および飲み口を持った通路構造を容易に実現することができる。また、中栓部は、前記基部通路、注出口および飲み口を形成する内筒の立体形状と、外筒のボトル体の口部内側に沿う単純形態とを利用して相互間に空間を形成し、ボトル栓のボトル体側と上端側とを空気断熱することができ、保温、保冷のいずれにも好適であるし、保冷時にボトル栓のボトル体側と外気との温度差のためにボトル栓の上端面に結露するのを防止することができる。しかも、内外筒は互いが回り止めおよび位置決め状態に嵌め合わされる上、内筒を外筒から下方に取り外して空間を解放しお手入れできるようにする。 With such a configuration, the bottle stopper is attached to the outside of the mouth of the bottle body at the outer stopper portion, and the outer periphery of the mouth portion of the bottle body is sheathed, and the inner stopper portion is difficult to obtain on the bottle body side. A passage structure having a base passage, a spout and a drinking mouth can be easily realized. Further, the inner plug portion forms a space between each other by utilizing the three-dimensional shape of the inner cylinder that forms the base passage, the spout and the drinking mouth, and the simple form along the inner side of the mouth portion of the outer cylinder bottle body. In addition, the bottle body side and the upper end side of the bottle stopper can be insulated from the air, which is suitable for both heat insulation and cold insulation, and because of the temperature difference between the bottle body side of the bottle stopper and the outside air during the cold preservation, Condensation on the upper end surface can be prevented. In addition, the inner and outer cylinders are fitted together in a non-rotating and positioning state, and the inner cylinder is removed downward from the outer cylinder so that the space can be released and maintained.
上記において、さらに、前記空間の上側および下側において内外筒間をシールしたシール部を設けたことを特徴とすることができる。 In the above, a seal portion that seals the inner and outer cylinders may be further provided on the upper side and the lower side of the space.
このような構成によれば、上記に加え、さらに、空間の上側および下側双方にシール部があることにより、空間は密閉空間となり、空気断熱効果が向上する上、内筒の空間内側面で結露が生じても外部に漏れ出る心配はない。 According to such a configuration, in addition to the above, since there are seal portions on both the upper side and the lower side of the space, the space becomes a sealed space, the air heat insulation effect is improved, and the inner surface of the space of the inner cylinder is improved. Even if condensation occurs, there is no worry of leaking outside.
上記において、さらに、注出口は、満杯状態の内容液をボトル体の傾けにより注出口から注出させるときの液面に対し吸気通路域を持つ位置および大きさに形成した吸気兼用の注出口としたことを特徴とすることができる。 In the above, the spout further includes a suction spout that is formed in a position and size having an intake passage area with respect to the liquid level when the full liquid content is poured out of the spout by tilting the bottle body. It can be characterized.
このような構成では、上記に加え、さらに、内容液が少ないときはもとより、満杯状態での注出時であっても内容液を注出口から飲み口へ注出しながら、周方向一部に口付けされる飲み口を通じた吸気を確保することができる。 In such a configuration, in addition to the above, not only when the content liquid is small, but also when pouring out in the full state, the content liquid is spouted from the spout to the drinking mouth while partly in the circumferential direction. Inhalation through the mouth can be ensured.
本発明の片開きボトルは、ボトル体の口部に上記の各発明のいずれかのボトル栓を装着してボトル本体をなし、ボトル栓にその前部寄りとした注出口に対し後部寄りとなるヒンジ連結部にて片開き蓋を開閉できるように支持し、片開き蓋は閉じ状態にて飲み口内に進入して前記注出口をシール部材で閉じるようにしたことを特徴とする。 The single-open bottle of the present invention has a bottle body by attaching the bottle stopper of any of the above inventions to the mouth of the bottle body, and is closer to the rear than the spout that is closer to the front of the bottle stopper. The hinge opening is supported so that the single-opening lid can be opened and closed, and the single-opening lid enters the drinking mouth in a closed state, and the spout is closed with a seal member.
このような構成では、片開き蓋は、その閉じ状態において、面積の大きな飲み口を閉じる必要がなく、飲み口に開口している面積の小さな吸気兼用となる注出口1つをシールして閉じるだけで、内容液の流出はもとより少しの漏れ出しも阻止することができる。 In such a configuration, in the closed state, the one-sided lid does not need to close the drinking mouth having a large area, and seals and closes one spout serving as a small intake opening that is open to the drinking mouth. In this way, it is possible to prevent the leakage of the content liquid as well as the slight leakage.
本発明のそれ以上の特徴は、以下の具体的な説明および図面によって明らかになる。また、本発明の各特徴はそれ自体単独で、あるいは複合して種々な組み合わせで採用することができる。 Further features of the present invention will become apparent from the following specific description and drawings. Each feature of the present invention can be used alone or in combination with various combinations.
本発明のボトル栓の基本構成によれば、ボトル体からの内容液を基部通路に受け入れて注出口へスムーズに案内し、注出口から飲み口に注出して受けて飲み口周方向一部への口付けにより、飲み口への内容液の注出状態や注出量を確認して過不足ない思い通りの注出調節の基に容易に飲めるようにする。 According to the basic configuration of the bottle stopper of the present invention, the content liquid from the bottle body is received in the base passage and smoothly guided to the spout, and is poured out from the spout into the spout and received in a part of the peripheral direction of the spout. By checking the state and amount of the liquid dispensed to the drinking mouth, it is easy to drink based on the desired dispensing control.
特に、ボトル栓が外栓部でボトル体の口部を外装するように装着できて、しかも、中栓部で前記基部通路、注出口および飲み口を持った複雑な通路構造を容易に実現する。また、中栓部が形成する閉空間による空気断熱によりボトル体の保温、保冷特性を高められる。同時に、保冷時に外気との温度差のためにボトル栓の上端面に結露するのを防止できる。しかも、内外筒は互いが回り止めおよび位置決め状態に嵌め合わされる上、内筒を外筒から下方に取り外して閉空間を解放しお手入れできるようにする。 In particular, the bottle stopper can be mounted so as to cover the mouth of the bottle body with the outer stopper, and a complicated passage structure having the base passage, the spout and the drinking mouth is easily realized at the inner stopper. . Further, the heat insulation and cold insulation characteristics of the bottle body can be enhanced by the heat insulation by the closed space formed by the inner plug portion. At the same time, it is possible to prevent condensation on the upper end surface of the bottle stopper due to a temperature difference from the outside air during cold storage. In addition, the inner and outer cylinders are fitted to each other in a non-rotating and positioning state, and the inner cylinder is removed downward from the outer cylinder so that the closed space can be released and maintained.
上記に加え、さらに、中栓部はボトル体の口部への装着によって口部との間をシールでき、内外筒の間がシールされているので、内容液が漏れ出ることはない。 In addition to the above, since the inner plug portion can be sealed between the mouth portion by being attached to the mouth portion of the bottle body and the space between the inner and outer cylinders is sealed, the content liquid does not leak out.
上記に加え、さらに、注出口の位置および大きさによって、内容液が少ないときはもとより、満杯状態での注出時であっても内容液を注出口から飲み口へ注出しながら、周方向一部に口付けされる飲み口を通じた吸気を確保することができる。 In addition to the above, depending on the position and size of the spout, not only when the content liquid is small, but also when the liquid is being poured out in the full state, Inhalation can be ensured through the drinking mouth attached to the part.
本発明の片開きボトルによれば、片開き蓋は、その閉じ状態において、面積の大きな飲み口を閉じる必要がなく、飲み口に開口している面積の小さな吸気兼用となる注出口1つをシールして閉じるだけで、内容液の流出はもとより少しの漏れ出しも阻止することができる。 According to the single-open bottle of the present invention, the single-open lid does not need to close a large-sized drinking mouth in the closed state, and has a single spout serving as a small-sized intake opening opened to the drinking mouth. By simply sealing and closing, it is possible to prevent the leakage of the content liquid as well as any leakage.
以下、本発明のボトル栓およびこれを用いた片開きボトルにつき図1〜図10に示す実施の形態に基づき詳細に説明する。 Hereinafter, the bottle stopper of the present invention and the single-open bottle using the same will be described in detail based on the embodiment shown in FIGS.
本実施の形態の片開きボトルは図1に示すように、ステンレス製の内壁及び外壁の間に真空断熱空間2を有するボトル体としての真空二重容器1と、この真空二重容器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を介して真空二重容器1に装着されたボトル栓である合成樹脂製の栓体5とによりボトル本体20をなしている。このボトル本体20にはその栓体5が形成する上端部の片側、具体的には背面側に回動軸6によるヒンジ連結部10を中心にボトル本体20の上端部に被さって栓体5に有する直飲み用の飲み口14を閉じ、また開く開閉動作をする片開き蓋7が設けられている。しかし、ボトル本体20は断熱性の有無、金属製、非金属製、飲み口14の構造など自由に設計でき、具体的な構造は特に問わない。また、片開き蓋7の材料も特に問うものではない。片開き蓋7とボトル本体20との間には片開き蓋7を閉じ状態にロックし、またそのロックを解除するロック機構8が設けられている。 As shown in FIG. 1, the single-open bottle of the present embodiment includes a vacuum double container 1 as a bottle body having a vacuum heat insulating space 2 between a stainless inner wall and an outer wall, and a mouth of the vacuum double container 1. A bottle main body 20 having a female screw threadedly engaged with a male screw 3 formed on the outer wall of the portion 1a and a synthetic resin plug body 5 which is a bottle stopper mounted on the vacuum double container 1 through a seal packing 9. I am doing. The bottle main body 20 covers the upper end portion of the bottle main body 20 on one side of the upper end portion formed by the plug body 5, specifically, on the back surface, centering on the hinge connecting portion 10 by the rotating shaft 6. A single-open lid 7 that opens and closes the drinking port 14 for direct drinking is provided. However, the bottle main body 20 can be freely designed such as the presence or absence of heat insulation, metal, non-metal, and the structure of the drinking mouth 14, and the specific structure is not particularly limited. Further, the material of the single lid 7 is not particularly limited. Between the single-opening lid 7 and the bottle body 20, there is provided a lock mechanism 8 that locks the single-opening lid 7 in a closed state and releases the lock.
図示例の上記真空二重容器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に装着された栓体5とほぼ同径に形成されている。真空二重容器1の胴部1bや栓体5部を片手持ちして、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の開放後に飲み口14による直飲み動作を行い易い形状になっている。しかし、図示例の片開き蓋7は回動軸6まわりに装着した蔓巻きタイプのばね131により開き方向に付勢してある。従って、片開き蓋7のロック機構8による閉じ位置へのロックは蔓巻きばね131の付勢に抗して行われ、このロックが解除されると片開き蓋7は蔓巻きばね131の付勢により自動的に開かれる。このような開き方向への付勢はボトル本体20の飲み口14まわりに設けた弾性体や、片開き蓋7に設けた飲み口14をシールする弾性を有したシールパッキン16などによって代替することもできる。 The vacuum double container 1 in the illustrated example has a barrel portion 1b that is slim enough to be held by one hand, and the upper portion of the barrel portion 1b is formed to have substantially the same diameter as the plug body 5 attached to the mouth portion 1a. Has been. Holding the body 1b and the plug 5 of the vacuum double container 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 opening lid 7 accompanying this, The shape is such that a direct drinking operation by the drinking mouth 14 is easily performed after the lid 7 is opened. However, the single-opening lid 7 in the illustrated example is urged in the opening direction by a vine type spring 131 mounted around the rotation shaft 6. Therefore, the locking mechanism 8 of the single-open lid 7 is locked to the closed position against the bias of the vine spring 131. When this lock is released, the single-open lid 7 is biased by the vine spring 131. Will be opened automatically. Such urging in the opening direction is replaced by an elastic body provided around the drinking mouth 14 of the bottle body 20 or a seal packing 16 having elasticity for sealing the drinking mouth 14 provided on the one-sided lid 7. You can also.
ここで、本実施の形態での栓体5は図1に示すように、金属製真空二重容器1内に通じる基部通路52a1と、この基部通路52a1に注出口52a3を介して通じた直飲みできる飲み口14とを、注出口52a3の面積に対し基部通路52a1および飲み口14の両面積を大きくしている。これにより、金属製真空二重容器1から流出してくる内容液を大きな面積の基部通路52a1から面積が小さい注出口52a3を通じこの注出口52a3よりも面積の大きな飲み口14に注出させることになる。この結果、一旦面積の大きな基部通路52a1に内容液を受け入れて面積の小さな注出口52a3へスムーズに案内できる。また、注出口52a3からはそれよりも面積が大きい飲み口14に注出されて受けられ、飲み口14に受けた注出内容液はその面積が大きいことを利用した周方向一部への口付け状態にて、従って飲み口14ではもとより注出口52a3での吸気を邪魔することなくスムーズな注出状態を得て、飲み口14への内容液の注出状態や注出量を確認しながらの過不足ない思い通りの注出調節の基に容易に飲めるようにする。従って、金属製真空二重容器1からの内容液を一旦面積の大きな基部通路52a1に受け入れて面積の小さな注出口52a3へスムーズに案内し、注出口52a3からはそれよりも面積が大きい飲み口14に注出して受けて、それを面積の大きな飲み口14周方向一部への口付けにより、飲み口14ではもとより注出口52a3での吸気を邪魔せずスムーズに注出させながら飲み口14への内容液の注出状態や注出量を確認して過不足ない思い通りの注出調節の基に容易に飲めることになる。 Here, as shown in FIG. 1, the stopper body 5 in the present embodiment includes a base passage 52a1 communicating with the inside of the metal vacuum double container 1, and a direct drinking through the base passage 52a1 through the spout 52a3. The area of the base passage 52a1 and the mouthpiece 14 is made larger than the area of the spout 52a3. Thus, the content liquid flowing out from the metal vacuum double container 1 is poured out from the large-area base passage 52a1 through the small-area spout 52a3 to the spout 14 having a larger area than the spout 52a3. Become. As a result, the content liquid can be once received into the base passage 52a1 having a large area and smoothly guided to the spout 52a3 having a small area. Further, from the spout 52a3, it is poured into and received by the spout 14 having a larger area, and the spout content liquid received at the spout 14 is parted in the circumferential direction using the large area. In the state, therefore, it is possible to obtain a smooth pouring state without interfering with the intake at the spout 52a3 as well as at the spout 14 and confirming the state and amount of the liquid dispensed to the spout 14 Make it easy to drink on the basis of the desired dispensing control. Accordingly, the content liquid from the metal vacuum double container 1 is once received in the base passage 52a1 having a large area and smoothly guided to the spout 52a3 having a small area, and the spout 14 having a larger area than the spout 52a3. The mouth of the large mouth 14 is attached to a part of the periphery of the mouth 14 so that the air can be smoothly poured into the mouth 14 from the mouth 52a3 without disturbing the air at the outlet 52a3. It is easy to drink based on the desired dispensing control by checking the dispensing state and amount of the liquid contents.
また、片開き蓋7は閉じ状態において、飲み口14内に進入して注出口52a3をシールパッキン16で閉じるようにしており、面積の大きな飲み口14を閉じる必要がなく、飲み口14に開口している面積の小さな吸気兼用となる注出口52a3の1つをシールして閉じるだけで、内容液の流出はもとより少しの漏れ出しも阻止することができる。 Further, in the closed state, the single lid 7 enters the drinking mouth 14 and closes the spout 52a3 with the seal packing 16, so that it is not necessary to close the drinking mouth 14 having a large area, and the opening is opened to the drinking mouth 14. By simply sealing and closing one of the spouts 52a3 that is also used as a small intake area, it is possible to prevent not only the outflow of the content liquid but also a slight leak.
栓体5は、また、金属製真空二重容器1の口部1a外側に装着される外栓部51と、この外栓部51から口部1a内に入って基部通路52a1、注出口52a3および飲み口14を形成する中栓部52とを有し、中栓部52は、口部1a内側に沿う外筒52bと、基部通路52a1、注出口52a3および飲み口14を有して前記外筒52bに嵌め合わされて、相互間にシール構造を有した密閉中空部となる空間53を形成している。これにより、栓体5が外栓部51で口部1a外側に装着されて口部1a外回りを外装して、しかも、中栓部52で金属製真空二重容器1の側では得にくい基部通路52a1、注出口52a3および飲み口14を持った複雑な通路構造を容易に実現することができる。また、中栓部52は、基部通路52a1、注出口52a3および飲み口14を形成する内筒52aの立体形状と、外筒52bの口部1a内側に沿う単純形態とを利用して相互間に空間53を形成し、栓体5の金属製真空二重容器1側と上端側とを空気断熱することができ、保温、保冷のいずれにも好適である。特に、保冷時に栓体5の金属製真空二重容器1側と外気との温度差のために栓体5の上端面に結露するのを防止することができるし、空間53は内筒52aと外筒52bとの嵌め合わせ部間でのシール構造による密閉中空部であるので、内筒52aの空間53内表面に結露することはあっても流出することはない。このように、栓体5が外栓部51で口部1aを外装するように装着できて、しかも、中栓部52で基部通路52a1、注出口52a3および飲み口14を持った複雑な通路構造を容易に実現する。また、中栓部52が形成する空間53による空気断熱により保温、保冷特性を高められる。同時に、保冷時に外気との温度差のために栓体5の上端面に結露するのを防止できるし、空間53は内筒52a、外筒52b間でのシール構造により密閉空間で内筒52aの空間内表面に結露することはあっても流出することはないので、お手入れが不要となる。 The plug body 5 also includes an outer plug portion 51 mounted on the outside of the mouth portion 1a of the metal vacuum double container 1, and a base passage 52a1, a spout 52a3, The inner plug portion 52 that forms the drinking mouth 14 has an outer cylinder 52b along the inner side of the mouth portion 1a, a base passage 52a1, a spout 52a3, and the drinking mouth 14, and the outer cylinder. The space 53 is formed as a sealed hollow portion having a sealing structure between them by being fitted to the 52b. As a result, the plug body 5 is attached to the outside of the mouth portion 1a by the outer plug portion 51 to externally surround the mouth portion 1a, and the base passage is difficult to obtain on the metal vacuum double container 1 side by the inner plug portion 52. A complicated passage structure having 52 a 1, spout 52 a 3 and drinking mouth 14 can be easily realized. Further, the inner plug portion 52 uses a three-dimensional shape of the inner cylinder 52a that forms the base passage 52a1, the spout 52a3, and the drinking mouth 14 and a simple configuration along the inner side of the mouth portion 1a of the outer cylinder 52b. The space 53 can be formed, and the metal vacuum double container 1 side and the upper end side of the plug body 5 can be thermally insulated by air, which is suitable for both heat insulation and cold insulation. In particular, it is possible to prevent condensation on the upper end surface of the plug body 5 due to a temperature difference between the metal vacuum double container 1 side of the plug body 5 and the outside air during the cold insulation, and the space 53 includes the inner cylinder 52a. Since it is a sealed hollow portion with a seal structure between the fitting portions with the outer cylinder 52b, it does not flow out even if condensation occurs on the inner surface of the space 53 of the inner cylinder 52a. In this way, the plug body 5 can be mounted so as to cover the mouth portion 1a with the outer plug portion 51, and the inner passage portion 52 has the base passage 52a1, the spout 52a3, and the drinking mouth 14 in a complicated passage structure. Is easily realized. In addition, heat insulation and cold insulation characteristics can be enhanced by air insulation by the space 53 formed by the inner plug portion 52. At the same time, it is possible to prevent dew condensation on the upper end surface of the plug body 5 due to a temperature difference from the outside air during cold storage, and the space 53 is a sealed space between the inner cylinder 52a and the outer cylinder 52b. Even if condensation occurs on the inner surface of the space, it does not flow out, so no maintenance is required.
外栓部51は、真空二重容器1の口部1aの前記雄ねじ3に螺合して口部1aを覆うほぼ円筒形をなし、中栓部52は外栓部51の内側で口部1a内側進入し口部1aの段部に前記シールパッキン9を圧接させて真空二重容器1を密閉するように構成され、外栓部51に中栓部52が嵌めあわされて栓体5を形成している。飲み口14は中栓部52の天面のヒンジ連結部10とは反対の側、具体的には前部側に偏って位置し、片開き蓋7がヒンジ連結部10を中心に開いて後部側に起立し後傾した状態においてボトル本体20を前傾させたときに、片開き蓋7の邪魔なしに口を付けやすく、直飲みしやすいようにしている。 The outer plug portion 51 is formed in a substantially cylindrical shape that covers the mouth portion 1a by being screwed into the male screw 3 of the mouth portion 1a of the vacuum double container 1, and the inner plug portion 52 is located inside the outer plug portion 51 at the mouth portion 1a. It is configured to enter the inside and seal the vacuum double container 1 by pressing the seal packing 9 against the step portion of the mouth portion 1a, and the inner plug portion 52 is fitted to the outer plug portion 51 to form the plug body 5. is doing. The drinking mouth 14 is located on the top surface of the inner plug portion 52 opposite to the hinge connecting portion 10, specifically, on the front side, and the one-sided lid 7 is opened around the hinge connecting portion 10 to the rear portion.

The drinking mouth 14 has a dish shape as shown in FIGS. 7 and 8 with the bottom portion deepening from the rear to the front and the upper end rising from the rear to the front. When the bottle body 20 is tilted until the liquid level 36 reaches the front end 14a of the drinking mouth 14, as shown in FIG. 1, when the bottle body 20 is almost full, the content liquid that has flowed out through the spout 52a3 is accumulated in the front portion of the drinking mouth 14. The portion 14b is formed, and after the content liquid is guided to the reservoir portion 14b from the large-diameter base passage 52a1 to the guide passage 52a2 that narrows toward the spout 52a3, direct discharge is prevented by the spout 52a3. It has a small dam portion 52a4 that exhibits the function of stopping or flowing out by tilting the main body 20 and pouring it further down to the width of the guide channel that is easy to drink directly. I can drink directly. By adjusting the amount of outflow from the front end 14a of the drinking mouth 14, it is possible to drink directly and without any disturbance. 3 and 6, the spout 52a3 has a larger length in the front-rear direction in the radial direction than the width that regulates the width of the guide channel, and the liquid level 36 shown in FIG. Since the intake passage area 52a5 is secured at the rear of the spout 52a3 even when the liquid flows out from the full state, the content liquid can be smoothly discharged without being disturbed. As a result, the spout 52a3 forms a position and size having the suction passage area 52a5 with respect to the liquid level 36 when the full liquid content is poured out of the spout 52a3 by tilting the bottle body 20. The spout 52a3 is not only when the content liquid is low, but also while being poured out in a full state, while the content liquid is poured out from the spout 52a3 to the drinking spout 14, it is applied to a part of the circumferential direction. Inhalation through the drinking mouth 14 can be ensured.

By abutting, the return position is restricted, and it is prevented from coming out of the pocket 41 forward. Further, the engaging portion 31 on the bottle body 20 side is formed so as to protrude from the upper end of the outer plug portion 51 as shown in FIGS. 1 and 7, and the peripheral wall 7 b of the one-sided lid 7 escapes from this, FIG. 2 and FIG. 7, a notch 7d as shown in FIG. 8 is provided, and a hook 321b of the engaging / disengaging member 321 faces the notch 7d from the inside as shown in FIGS.
したがって、ロック解除操作部材322の過剰な操作を阻止してそれ自体や他の部材などの損傷を防止して、しかも、片開き蓋7はロック解除操作の最終段階での初期開きにより係脱部材321によるロック位置から上方へ退避しているので、ロック解除操作部材322や片開き蓋7が解放されて係脱部材321がばね35の付勢によってロック解除操作部材322を伴い係合位置に復帰したとき、片開き蓋7を再度ロックすることはなく、片開き蓋7は、ばね131の付勢によって自動的に確実に開かれる。片開き蓋7が開き位置から閉じられると、係脱部材321はボトル本体20側の係合部31との係合位置に復帰しているが、ロック解除操作部材322の内側で単独にスライドできるので、片開き蓋7の閉じの最終段階でフック321bが係合部31に上方から当接していくときに、それらの一方または双方の斜面や曲面での滑りによって係脱部材321がばね35に抗し一時的に後方へ単独で退避させられながら係合部31との係合位置に達する。フック321bが係合部31との係合位置に達したとき、係脱部材321はばね35の付勢により係合位置に単独で復帰しフック321bが係合部31に図1に示すように係合するので、片開き蓋7を自動的に閉じ状態にロックする。なお、片開き蓋7を閉じるのに、自由端部の上面および前面に掛けて位置するロック解除操作部材322を押圧する形で閉じ操作すればよく、このように閉じ操作はロック解除操作部材322に対する押圧力を働かせるだけであるので、前後にスライドするロック解除操作部材322を不用意に移動させることはないし、ロック解除操作部材322はポケット41の底部に受けられて破損するようなことはない。 Accordingly, excessive operation of the unlocking operation member 322 is prevented to prevent damage to itself and other members, and the one-sided lid 7 is engaged and disengaged by an initial opening at the final stage of the unlocking operation. Since the lock release operation member 322 and the one-sided lid 7 are released, the engagement / disengagement member 321 returns to the engagement position with the lock release operation member 322 by the bias of the spring 35. Then, the single-open lid 7 is not locked again, and the single-open lid 7 is automatically and reliably opened by the bias of the spring 131. When the single-open lid 7 is closed from the open position, the engagement / disengagement member 321 returns to the engagement position with the engagement portion 31 on the bottle body 20 side, but can be slid independently inside the lock release operation member 322. Therefore, when the hook 321b comes into contact with the engaging portion 31 from above at the final stage of closing the one-sided lid 7, the engagement / disengagement member 321 is brought into contact with the spring 35 by sliding on one or both of the slopes and curved surfaces. However, it reaches the engagement position with the engagement portion 31 while being temporarily retracted rearward. When the hook 321b reaches the engagement position with the engagement portion 31, the engagement / disengagement member 321 is independently returned to the engagement position by the bias of the spring 35, and the hook 321b is brought into the engagement portion 31 as shown in FIG. Since it is engaged, the single-open lid 7 is automatically locked in the closed state. In order to close the single-open lid 7, it is only necessary to perform a closing operation by pressing the unlocking operation member 322 positioned on the upper surface and the front surface of the free end, and the closing operation is thus performed by the unlocking operation member 322. The unlocking operation member 322 that slides back and forth is not moved carelessly, and the unlocking operation member 322 is received at the bottom of the pocket 41 and is not damaged. .
しかも、図8に示すようにロック解除操作部材322は広く大きなものとして設けられるので、操作性が向上し動きが安定しがたつかない利点がある。また、その内側の係脱部材321も外部に露出させないで大きくすることができ、係合音を伴うロック感やロックの確実性が増す。また、片開き蓋7上の主要部材であるロック解除操作部材322は係脱部材321、安全ストッパ33と共に飲み口14とほぼ対応する位置にあって、しかも、ほぼ飲み口14に対応する鉤型面範囲内に収まって設けられる。 In addition, as shown in FIG. 8, since the unlocking operation member 322 is provided as a large and large one, there is an advantage that the operability is improved and the movement is not stable. Further, the engaging / disengaging member 321 on the inner side can be enlarged without being exposed to the outside, and the locking feeling accompanied by the engagement sound and the certainty of the locking are increased. Further, the unlocking operation member 322 which is a main member on the one-sided lid 7 is in a position substantially corresponding to the drinking mouth 14 together with the engagement / disengagement member 321 and the safety stopper 33, and is also a saddle type corresponding to the drinking mouth 14. Provided within the surface range.
前記安全ストッパ33は樹脂製の一体成形品で、図1、図2、図8に示すような左右方向に長い操作頭部33aを有し、ロック解除操作部材322の上辺322aに形成した凹部61内を左右にスライドできるように収容される。安全ストッパ33は凹部61の底部に設けた図1、図9に示すような左右のスライド窓61aに操作頭部33aの下面の左右方向中央部の両側に一体成形した図1、図9に示すようなフック片33bを上方から弾性係合させて抜け止めし、左右にスライドできるように支持される。操作頭部33aの下面にはさらに、図9に示すようなストッパ33cが一体成形されている。安全ストッパ33のロック解除操作を阻止する図1に示す阻止位置では、ストッパ33cがポケット41の天面部の後部に一体成形された受け止め突起41bと対向して、ロック解除操作部材322が後退操作されると、従って、ロック解除操作されると、それらストッパ33cと受け止め突起41bとが突っ張って、後退操作、従ってロック解除操作を阻止する。また、安全ストッパ33の図8に示す阻止解除位置では、ストッパ33cが受け止め突起41bとの対向位置から外れ、ロック解除操作部材322が後退させられても、従って、ロック解除操作されても、ストッパ33cは受け止め突起41bに当接せず、後退操作、従ってロック解除操作を阻止しない。なお、図示しないがフック片33bの一方とこれが摺動するスライド窓61aの縁との間でクリック係合する係合部を前記阻止位置と阻止解除位置とに対応する2箇所に設け、安全ストッパ33をいずれかの位置に選択的に安定させられるようにする。なお、安全ストッパ33は横スライド方式の動作部材としたが、押し込み方向での動作部材とすることもできる。 The safety stopper 33 is an integrally molded product made of resin, has a long operation head 33a in the left-right direction as shown in FIGS. 1, 2, and 8, and has a recess 61 formed on the upper side 322a of the unlocking operation member 322. It is housed so that it can slide left and right inside. The safety stopper 33 is integrally formed on the left and right sliding windows 61a as shown in FIGS. 1 and 9 provided at the bottom of the recess 61 on both sides of the central portion in the left and right direction of the lower surface of the operation head 33a. Such a hook piece 33b is elastically engaged from above to prevent it from coming off, and is supported so that it can slide to the left and right. Further, a stopper 33c as shown in FIG. 9 is integrally formed on the lower surface of the operation head 33a. In the blocking position shown in FIG. 1 where the lock release operation of the safety stopper 33 is blocked, the lock release operation member 322 is retracted with the stopper 33c facing the receiving protrusion 41b formed integrally with the rear portion of the top surface of the pocket 41. Accordingly, when the unlocking operation is performed, the stopper 33c and the receiving projection 41b are stretched to prevent the backward operation and thus the unlocking operation. Further, at the blocking release position shown in FIG. 8 of the safety stopper 33, even if the stopper 33c is disengaged from the position facing the receiving projection 41b and the unlocking operation member 322 is retracted, and therefore the unlocking operation is performed, the stopper 33c does not contact the receiving projection 41b and does not prevent the backward operation and hence the unlocking operation. Although not shown in the drawing, an engagement portion that click-engages between one of the hook pieces 33b and the edge of the sliding window 61a on which the sliding is made is provided at two locations corresponding to the blocking position and the blocking release position, and a safety stopper 33 can be selectively stabilized at any position. Although the safety stopper 33 is a lateral slide type operating member, the safety stopper 33 may be an operating member in the pushing direction.
なお、栓体5の中栓部52は、ボトル体1の口部1a内側に沿う外筒52bと、この外筒52bに嵌め合わされて相互間に空間53を形成した内筒52aとの組み合わせとするのに、上記実施の形態とは別に、中栓部52は、基部通路52a1の下端部外周でボトル体1の口部1aとの間をシールするシールパッキン9と、空間53の上側および下側の少なくとも一方において内外筒52a、52b間をシールしたシールパッキン37とを設ければ、中栓部52はボトル体1の口部1aへの装着によって口部1aとの間をシールでき、内外筒52a、52bの間がシールされているので、内容液が漏れ出ることはない。よりよくは上記実施の形態のように空間53の上側および下側双方に内外筒間のシール部があれば、既述したように空間53は密閉空間となり、空気断熱効果が向上する上、内筒52aの空間53内側面で結露が生じても外部に漏れ出る心配はなく、内外筒52a、52b間のシール部が弾性を持ったシールパッキン37のみによるものであれば、内外筒52a、52bの嵌め合わせを外して空間53内側を露出させ、結露水などを排出し、拭い取るお手入れができ、シール部が既述したように超音波溶着や接着、無理嵌め構造などの一体化を伴うものであれば、内側に結露してもお手入れは不要となる。 The inner stopper portion 52 of the stopper body 5 includes a combination of an outer cylinder 52b along the inner side of the mouth portion 1a of the bottle body 1 and an inner cylinder 52a fitted into the outer cylinder 52b to form a space 53 therebetween. Therefore, separately from the above-described embodiment, the inner plug portion 52 includes a seal packing 9 that seals between the outer periphery of the lower end portion of the base passage 52a1 and the mouth portion 1a of the bottle body 1, and an upper side and a lower side of the space 53. If the seal packing 37 that seals between the inner and outer cylinders 52a and 52b is provided on at least one of the sides, the inner plug portion 52 can seal between the mouth portion 1a by being attached to the mouth portion 1a of the bottle body 1, Since the space between the cylinders 52a and 52b is sealed, the content liquid does not leak out. More preferably, if there are seal portions between the inner and outer cylinders on both the upper side and the lower side of the space 53 as in the above embodiment, the space 53 becomes a sealed space as described above, and the air insulation effect is improved. Even if condensation occurs on the inner surface of the space 53 of the cylinder 52a, there is no risk of leaking to the outside. If the seal part between the inner and outer cylinders 52a, 52b is made of only the elastic seal packing 37, the inner and outer cylinders 52a, 52b The inside of the space 53 is exposed by removing the fitting, drained water, etc. can be drained and cleaned, and the seal part is integrated with ultrasonic welding, bonding, forced fitting structure, etc. as described above If it is a thing, even if it condenses inside, care is unnecessary.
ここで、中栓部52の内外筒52a、52bの組み合わせを着脱できるようにした実施の形態を示すと、図10に示すように内外筒52a、52b間の空間53の上側相互間に弾性を有したシールパッキン37によるシール部を設け、空間53の下側相互間はシールパッキン37の弾性嵌合による滑り止め機能による当たり保持による閉じ部としてあり、空間53を一応の閉空間にするように構成しているが、内外筒52a、52bはシールパッキン37による滑り止め力に打ち勝って嵌め合わせたり、嵌め合わせを外したりすることができる。 Here, when an embodiment in which the combination of the inner and outer cylinders 52a and 52b of the inner plug portion 52 is detachable is shown, elasticity is provided between the upper sides of the space 53 between the inner and outer cylinders 52a and 52b as shown in FIG. A seal portion is provided by the seal packing 37 that is provided, and the lower side of the space 53 is a closed portion by a contact-holding function by an anti-slip function by elastic fitting of the seal packing 37 so that the space 53 is temporarily closed. Although configured, the inner and outer cylinders 52a and 52b can be fitted to each other by overcoming the anti-slip force by the seal packing 37 or can be removed.
