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.

特に、特許文献１に記載のボトル栓は、真空二重容器の口部内に装着する栓本体と、真空二重容器の肩部に装着した肩部材に装着する栓カバーとの二重構造上の断熱効果から、真空二重容器で飲料などを保令しても栓カバー外面に結露することはない。また、しかし、二重構造部がなすデッドスペースが大きく、保冷時ではその内側に結露水が溜まってカビの発生などを見ることがあるので、お手入れの必要がある。このため、栓本体と栓カバーとを分離できるようにしており、結露水が溜まっても分解してお手入れできるようにしている。
特開２００６−１６０２７８号公報 In particular, the bottle stopper described in Patent Document 1 has a double structure of a stopper body attached to the mouth of the vacuum double container and a stopper cover attached to a shoulder member attached to the shoulder of the vacuum double container. Due to the heat insulation effect, no dew condensation is formed on the outer surface of the stopper cover even if the beverage is ordered in a vacuum double container. In addition, however, the dead space formed by the double structure is large, and during cold storage, condensed water may accumulate on the inside, and mold may be seen. For this reason, the plug body and the plug cover can be separated, and even if condensed water accumulates, they can be disassembled and maintained.
JP 2006-160278 A

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 walking or walking, the content liquid may be poured out into a full drinking mouth and overflow, or inhalation may not be possible.

そこで、本出願人は、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、注出口の面積に対し基部通路および飲み口の両面積を大きくして設けた改良構造を先に出願している（特願２００７−７９５６９号）。これにより、ボトル体から流出してくる内容液を大きな面積の基部通路から面積が小さい注出口を通じこの注出口よりも面積の大きな飲み口に注出させるが、一旦面積の大きな基部通路に内容液を受け入れて面積の小さな注出口へスムーズに案内できる。また、注出口からはそれよりも面積が大きい飲み口に注出されて受けられ、飲み口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、従って飲み口ではもとより注出口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。外面への結露対策としては、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嵌め合わされて相互間に断熱空間を形成した内筒と、の組み合わせとして対応でき、断熱空間によって保温、保冷のいずれにも好適なものとなった。   Therefore, the present applicant has a stopper attached to the upper end of the bottle body, a base passage that leads to the bottle body through the stopper body, and a drinking mouth that allows direct drinking to the base passage through the spout. Has previously filed an improved structure in which both the area of the base passage and the mouth are made larger than the area of the spout (Japanese Patent Application No. 2007-7969). As a result, the content liquid flowing out from the bottle body is poured from the base passage with a large area through the spout with a small area to the drinking mouth having a larger area than the spout, but once the content liquid is poured into the base passage with a large area. Can be smoothly guided to the small outlet. In addition, it is poured from the spout into a drinking spout with a larger area, and the content of the spout received at the spout is in a state of mouthing partly in the circumferential direction using the large area. Therefore, it is possible to obtain a smooth dispensing state without interfering with the intake at the spout as well as at the spout, and as much as possible while checking the state and amount of liquid dispensed to the spout. Make it easy to drink on the basis of regulation. As countermeasures for dew condensation on the outer surface, an outer plug part to be mounted on the outer side of the mouth part of the bottle body, and inside the mouth part of the bottle body from this outer plug part to form the base passage, spout and drinking mouth The inner plug portion has an outer cylinder along the inner side of the mouth of the bottle body, and has a base passage, a spout and a drinking mouth, and is fitted into the outer cylinder to provide a heat insulating space between them. It can be handled as a combination with the formed inner cylinder, and is suitable for both heat insulation and cold insulation by the heat insulating space.

一方、これらの栓の二重構造が複雑な上、二重構造部の上部と下部とに個別のシール部材を必要とし、部品点数、組み立て工数が多く製品コストが増大するし、シール部材を外しての分解掃除では手間が係る。   On the other hand, the double structure of these plugs is complicated, and separate seal members are required for the upper and lower parts of the double structure, which increases the number of parts and man-hours, increases the product cost, and removes the seal member. All disassembly and cleaning takes time.

そこで、本出願人は、図８に示すような構造が単純で表面への結露も防止でき、かつお手入れの不要なボトル栓も開発し、別途提案している（特願２００７−１３７６５号）。このお手入れ不要な構造は、図８に示すように飲み口ａを持った栓体ｂと、この栓体ｂの天板ｃの内側に断熱空間ｄを置いて当てがって超音波溶着などして気密状態で取り付けた蓋板ｅとで構成して、断熱空間ｄ内に露出する蓋板ｅの上面に結露するにしても流出することがなくお手入れ不要にし、かつ、栓体ｂとボトル体ｆとの間をシールするシール部材ｇを１つだけ設ければよいものとしている。   Accordingly, the present applicant has developed a bottle stopper that has a simple structure as shown in FIG. 8, can prevent condensation on the surface, and does not require maintenance, and has been proposed separately (Japanese Patent Application No. 2007-13765). As shown in FIG. 8, this maintenance-free structure includes a plug body b having a drinking mouth a and a heat insulation space d placed on the inner side of the top plate c of the plug body b, and ultrasonic welding or the like. The cover plate e is attached in an airtight state, and even if condensation is formed on the upper surface of the cover plate e exposed in the heat insulating space d, it does not flow out and does not require maintenance. Only one sealing member g for sealing between the bottle body f is required.

ところが、断熱空間ｄでの結露水の存在感は、ユーザによってはお手入れできることが望まれるし、お手入れできることに越したことはないと判断される。   However, the presence of condensed water in the heat insulating space d is desired to be cared for by some users, and it is determined that it has never passed that it can be cared for.

このような視点から、本発明の目的は、部品点数が少なく、分解、組み立てが簡単で全部品のお手入れができる安価な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。   From such a point of view, an object of the present invention is to provide an inexpensive bottle stopper that has a small number of parts, is easy to disassemble and assemble, and can be used for cleaning all parts, and a single-open bottle using the same. .

上記課題を解決するため、本発明のボトル栓は、ボトル体の口部に着脱できるように装着される栓体を有し、この栓体は、ボトル体の口部外側に着脱できるように装着される外栓部と、この外栓部の内側に直飲みできる飲み口を有して着脱できるように組み合わされ、ボトル体内には飲み口まわりのお手入れ用開放部を持った断熱空間形成部で臨んで通じ、かつ飲み口が外栓部上に突出する中栓部と、これら外栓部、中栓部、およびボトル本体の相互境界部にそれらいずれからも着脱できるように組み合わされて相互をシールし、少なくともこのシール状態で中栓部の前記お手入れ用開放部をシールするシール部材と、を備えたことを特徴としている。   In order to solve the above problems, the bottle stopper of the present invention has a stopper that can be attached to and detached from the mouth of the bottle body, and the stopper is attached to the outside of the mouth of the bottle body. Insulated space forming part that has a mouth part that can be taken directly inside and attached to the inside of the outer part so that it can be attached and detached, and has an open part for cleaning around the mouth part inside the bottle Are connected to each other so that they can be attached to and detached from the outer plug part, the inner plug part, and the mutual boundary part of the bottle body. And a sealing member that seals at least the maintenance opening of the inner plug portion in this sealed state.

このような構成では、ボトル体の口部に着脱できるように装着される栓体の部品点数が、外栓部、中栓部、シール部材の３つと少なく、分解、組み立ての工数も少なくなる。また、中栓部は外栓部の内側にその飲み口が外栓部上に突出するように位置する組み合わせを満足して、外栓部をボトル体の口部に装着し、この装着に際してシール部材が外栓部、中栓部、およびボトル体の口部の相互境界部に位置するようにしておくだけで、組立およびボトル体の口部への装着ができ、同時に、外栓部、中栓部、およびボトル体の口部の相互境界部をシールするのに併せ、中栓部に有する断熱空間形成部のお手入れ用開放部をシールすることができる。さらに、外栓部をボトル体の口部から取り外すことによって中栓部およびシール部材が少なくとも露出するので着脱可能な相互を分解できる。   In such a configuration, the number of parts of the plug body that can be attached to and detached from the mouth portion of the bottle body is as few as three of the outer plug portion, the inner plug portion, and the seal member, and the man-hours for disassembly and assembly are also reduced. In addition, the inner plug portion satisfies the combination in which the drinking port protrudes on the outer plug portion on the inner side of the outer plug portion, and the outer plug portion is attached to the mouth portion of the bottle body, and the seal is attached at the time of the attachment. The assembly and mounting to the mouth of the bottle body can be carried out at the same time as the member is positioned at the mutual boundary part of the outer stopper part, the inner stopper part, and the mouth part of the bottle body. In addition to sealing the mutual boundary part between the stopper part and the mouth part of the bottle body, it is possible to seal the opening part for maintenance of the heat insulating space forming part in the inner stopper part. Furthermore, since the inner plug part and the seal member are exposed at least by removing the outer plug part from the mouth part of the bottle body, the removable parts can be disassembled.

断熱空間形成部は、飲み口周りの軸線方向に形成されて外周間をお手入れ用開放部とした二重壁が形成しているものとすることができる。   The heat insulation space forming part may be formed in a double wall formed in the axial direction around the drinking mouth and having an opening between the outer periphery.

このような構成では、断熱空間形成部が飲み口周りでその軸線方向に重なった二重壁よりなり、それらの外周間がお手入れ用開放部をなして、外栓部とボトル体の口部との間をシールするシール部材直近に位置するので、外栓部、中栓部、およびボトル体の口部の相互境界部をシールするシール部材を共用してお手入れ用開放部をシールするのに好都合となる。   In such a configuration, the heat insulation space forming portion is composed of a double wall that is overlapped in the axial direction around the drinking mouth, and the outer periphery between them forms an opening for cleaning, and the outer plug portion and the mouth portion of the bottle body It is located in the immediate vicinity of the sealing member that seals between the two, so that the opening portion for maintenance is sealed by sharing the sealing member that seals the mutual boundary portion of the outer plug portion, the inner plug portion, and the mouth of the bottle body. Will be convenient.

シール部材は、断熱空間形成部のお手入れ用開放部に着脱できるように装着されてそのお手入れ開放部をシールしているものとすることができる。   The sealing member can be attached so as to be attachable to and detachable from the maintenance opening portion of the heat insulation space forming portion and seal the maintenance opening portion.

このような構成では、シール部材が中栓部の断熱空間形成部のお手入れ用開放部に着脱できるように装着されることで、お手入れ用開放部のシールを保証し、かつ、シール部材の取り外しによる断熱空間形成部のお手入れ用開放部を通じたお手入れを可能としながら、中栓部と外栓部との組み合わせによってシール部材が外栓部、中栓部、およびボトル体の口部の相互境界部をシールする位置に一義的に位置決めされて、人為的な位置決めが不要となる。   In such a configuration, the seal member is mounted so as to be detachable from the maintenance opening portion of the heat insulating space forming portion of the inner plug portion, so that the seal of the maintenance opening portion is guaranteed, and the seal member The sealing member can be attached to the outer plug portion, the inner plug portion, and the mouth portion of the bottle body by combining the inner plug portion and the outer plug portion while enabling the maintenance through the opening for cleaning the heat insulating space forming portion by removal. It is uniquely positioned at the position where the mutual boundary is sealed, and no artificial positioning is required.

中栓部は、シール部材を介してボトル体の口部に上方から着座し、外栓部は、ボトル本体への装着によってシール部材を介し中栓部を前記着座状態に押圧するものとすることができる。   The inner plug portion is seated from above on the mouth of the bottle body via the seal member, and the outer plug portion presses the inner plug portion into the seated state via the seal member when mounted on the bottle body. Can do.

このような構成では、中栓部がシール部材を介してボトル体の口部に上方から着座した状態で、外栓部がボトル本体への装着によってシール部材を介して前記着座状態に押圧されることで、中栓部はボトル本体の口部との嵌め合いのない着座だけの簡単な組み合わせで、ボトル本体の口部と外栓部との間に、中栓部の断熱空間形成部が心材となって確固に挟み付けられるので、外栓部、中栓部、およびボトル体の口部の相互境界部のシールがより確実に達成され、組み立て、装着の状態が安定する。   In such a configuration, the outer plug portion is pressed to the seated state via the seal member when mounted on the bottle body while the inner plug portion is seated from above on the mouth portion of the bottle body via the seal member. Therefore, the inner plug part is a simple combination with only a seating that does not fit with the mouth part of the bottle body, and the heat insulating space forming part of the inner stopper part is the core material between the mouth part of the bottle body and the outer stopper part. As a result, the outer plug portion, the inner plug portion, and the mouth of the bottle body are more reliably sealed, and the assembled and mounted state is stabilized.

断熱空間形成部は、飲み口と、シール部材による外栓部、中栓部、ボトル体の相互、およびお手入れ用開放部のシール域との間に、外栓部外からボトル体内への吸気路を有し、シール部材は、その吸気路の少なくとも外部開口部を有し、外栓部に設けた飲み口に対する開閉蓋が閉じられたときに、開閉蓋の一部によって閉じられるようにしているものとすることができる。   The heat-insulating space forming part is an air intake from the outside of the outer plug part to the inside of the bottle body between the drinking mouth and the sealing part of the outer plug part, the inner plug part, the bottle body, and the opening part for cleaning. The seal member has at least an external opening of the intake passage, and is closed by a part of the opening / closing lid when the opening / closing lid for the drinking mouth provided in the outer plug portion is closed. Can be.

このような構成では、直飲み中の飲み口から外れた位置の吸気路を通じ外気をボトル体内に自然吸気することができるし、吸気路が外栓部、中栓部、ボトル体の相互、およびお手入れ用開放部のシール域よりも内側に位置するので、それらのシールを損なったりシール構造を複雑にすることはない。また、吸気路の少なくとも上端部を前記シール部材が弾性を有して形成することで、開閉蓋を閉じるのと同時にその一部によって無理なく確実に閉じられる。   In such a configuration, the outside air can be naturally aspirated into the bottle through the intake passage that is away from the drinking mouth during direct drinking, and the intake passage is between the outer plug portion, the inner plug portion, the bottle body, and Since it is located on the inner side of the seal area of the open part for maintenance, those seals are not damaged and the seal structure is not complicated. In addition, since at least the upper end portion of the intake passage is formed with elasticity of the seal member, the opening / closing lid is closed at the same time as the opening / closing lid is closed without difficulty.

本発明の片開きボトルは、ボトル体の口部に上記各場合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飲み口に対し後部寄りとなるヒンジ連結部にて開閉蓋を片開きできるように支持し、開閉蓋は閉じ状態にて飲み口をシール部材で閉じるようにしたことを特徴とする片開きボトル。   The single-open bottle of the present invention has a bottle body by attaching the bottle stopper of any of the above cases to the mouth of the bottle body, and the hinge that is closer to the rear than the drinking mouth that is closer to the front of the bottle stopper. A single-open bottle characterized in that the opening / closing lid is supported by the connecting portion so that the opening / closing lid can be opened separately, and the drinking mouth is closed by a seal member in a closed state.

このような構成では、ボトル体の口部に装着したボトル栓の飲み口が前部寄りに位置しているので、ボトル体を前部と向かい合うように把持すれば、飲み口がボトル体の胴部よりも前部側、つまり自身の口側に寄って位置するので、直飲みするのにボトル体が邪魔にならない。また、片開きの開閉蓋は開かれるとボトル栓の後部寄りとなるヒンジ連結部側に立ち上がるので、前部寄りの飲み口からの直飲みを邪魔しないし、ボトル体を側方から把持した手の親指がボトル体の、片開きする開閉蓋を開き操作することになる前部に位置して、開き操作するのと同時にボトル体の前傾を伴いまたはそのまま飲み口を近付けて直飲みでき、前傾させても外栓部の天面は断熱空間形成部がシール部材で閉じられて断熱空間となっていることにより、保冷飲料による結露が生じない。さらに、断熱空間形成部内に結露水が生じた場合でも、前記分解によりボトル栓の全部品をお手入れできる。   In such a configuration, since the drinking mouth of the bottle stopper attached to the mouth portion of the bottle body is located closer to the front portion, if the bottle body is gripped so as to face the front portion, the drinking mouth will become the body of the bottle body. Because it is located closer to the front side than the part, that is, to the mouth side of itself, the bottle body does not get in the way to drink directly. In addition, when the openable lid is opened, it rises to the hinge connecting part near the back of the bottle stopper, so it does not interfere with direct drinking from the drinking mouth near the front, and the hand holding the bottle from the side. The thumb of the bottle body is located at the front part where the opening and closing lid that opens one side is opened, and at the same time as the opening operation is performed, the bottle body can be directly swallowed with the forward tilt of the bottle body or as it is, Even when tilted forward, the top surface of the outer plug portion has a heat insulating space formed by the heat insulating space forming portion being closed by a sealing member, so that condensation due to the cold beverage does not occur. Furthermore, even when condensed water is generated in the heat insulation space forming portion, all parts of the bottle stopper can be cleaned by the above decomposition.

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.

本発明のボトル栓によれば、部品点数が３つと少なく安価に供せる上、分解、組み立ての工数も少なく簡単に組み立て、分解ができ、分解は、中栓部に形成したボトル栓外面での結露を防止する断熱空間形成部の開放も併せなされるので、断熱空間形成部に結露水が生じることがあっても、その部分を含め全部品につきくまなく洗浄できるなど簡単にかつ十分にお手入れすることができ、長期に清潔に保てる。また、中栓部が外栓部の内側にその飲み口が外栓部上に突出するように位置する組み合わせと、外栓部をボトル体の口部に装着し、その際シール部材が外栓部、中栓部、およびボトル体の口部の相互境界部に位置させるだけで、組立およびボトル体の口部への装着に加え、必要なシールを満足してシール不良などなく安全使用することができる。さらに、外栓部をボトル体の口部から取り外せば中栓部およびシール部材が少なくとも露出するので着脱可能な相互を容易に分解できる。   According to the bottle stopper of the present invention, the number of parts can be reduced to three, and it can be provided at low cost, and it can be easily assembled and disassembled with few man-hours for disassembling and assembling. The heat insulation space forming part that prevents condensation is also opened, so that even if condensation water is generated in the heat insulation space forming part, all parts including that part can be cleaned easily and thoroughly. Can be kept clean for a long time. In addition, a combination in which the inner plug portion is positioned inside the outer plug portion so that the drinking port protrudes above the outer plug portion, and the outer plug portion is attached to the mouth portion of the bottle body, in which case the sealing member is the outer plug In addition to assembling and mounting to the mouth of the bottle body, the required seal is satisfied and the product can be used safely without any defective seals. Can do. Furthermore, if the outer plug part is removed from the mouth part of the bottle body, the inner plug part and the seal member are at least exposed, so that the removable parts can be easily disassembled.

断熱空間形成部が飲み口周りで軸線方向での二重壁で、その外周間がお手入れ用開放部となって、外栓部とボトル体の口部との間をシールするシール部材直近に位置し、外栓部、中栓部、およびボトル体の口部の相互境界部をシールする１つのシール部材を共用してお手入れ用開放部をシールするのに、特に大きな断面域を必要とせずシール部材の材料費、成形費を含めコスト高にならない。   The heat insulation space forming part is a double wall in the axial direction around the drinking mouth, and the outer periphery is an open part for cleaning, close to the seal member that seals between the outer plug part and the mouth part of the bottle body A particularly large cross-sectional area is required to seal the open part for maintenance by using a single sealing member that is located and seals the mutual boundary part of the outer stopper part, the inner stopper part, and the mouth part of the bottle body. It does not increase the cost including the material cost and molding cost of the seal member.

シール部材が、中栓部の断熱空間形成部のお手入れ用開放部に装着されて、お手入れ用開放部のシールを保証しながら、その取り外しにて断熱空間形成部のお手入れ用開放部を通じお手入れできるようにし、中栓部と外栓部との組み合わせによってシール部材が外栓部、中栓部、およびボトル体の口部間の必要シール位置に特別な手間なく的確に位置決めされ確実にシールすることができる。   The seal member is attached to the opening part for the maintenance of the heat insulation space forming part of the inner plug part, and the seal opening of the care opening part is ensured while the seal member is removed to pass through the maintenance opening part of the heat insulation space forming part. It is easy to clean, and the combination of the inner plug part and the outer plug part ensures that the sealing member is accurately positioned at the required sealing position between the outer plug part, the inner plug part, and the mouth of the bottle body without any special effort. Can be sealed.

中栓部が外栓部との組み合わせ上、シール部材を介して、着座しただけのボトル本体の口部とそれに装着した外栓部との間に、自身の断熱空間形成部が心材となって確固に挟み付けられて、外栓部、中栓部、およびボトル体の口部の相互境界部のシールがより確実に達成されるのに併せ。組み立て、装着の状態が安定する。   In combination with the outer plug part, the inner plug part is the core material between the mouth part of the bottle body just seated and the outer plug part attached to it through the seal member. In addition to being firmly clamped, the sealing of the outer plug part, the inner plug part, and the mutual boundary part of the mouth part of the bottle body can be achieved more reliably. Assembling and mounting are stable.

直飲みに際し、飲み口から外れた位置の吸気路を通じ外気をボトル体内に自然吸気するので、飲み口内での吸気時のような特別な吸気調整なく飲料をスムーズに流出させられるし、吸気路が必要シール域の内側にあってシールを損なったり複雑にしたりしないので、機能不全や、コスト上昇の原因にはならない。また、吸気路の少なくとも上端部が弾性を有するシール部材よりなり、開閉蓋を閉じるのと同時にその一部によって無理なく確実に閉じられる。   When drinking directly, outside air is naturally aspirated into the bottle through the intake passage that is out of the mouth, allowing the beverage to flow smoothly without any special inspiration adjustments, such as when inhaling in the mouth. Since it is inside the required seal area and does not damage or complicate the seal, it does not cause malfunction or increase in cost. Further, at least the upper end portion of the intake passage is made of an elastic seal member, and at the same time as the opening / closing lid is closed, it is reliably closed without difficulty by a part thereof.

本発明の片開きボトルによれば、飲み口があるボトル体の前部側と向かい合うように把持すれば飲み口からの直飲みにボトル体が邪魔にならいし、片開きの開閉蓋は後部寄りとなるヒンジ連結部を中心に後方側に寄って開かれて前部寄りの飲み口からの直飲みを邪魔しないので、直飲みしやすいものとなる。また、ボトル体を側方から把持すると手の親指がボトル体の前部に位置して片開きの開閉蓋の前部自由端側での開き操作が簡単に行えるし、ボトル体の前傾を伴いまたはそのまま飲み口を近付けて連続または並行したほぼ一挙動にて楽に直飲みでき、天面は断熱空間形成部が閉じられて断熱空間となり保冷飲料による結露がないので前傾時に気になったり濡れたりする問題もない。さらに、断熱空間形成部内に結露水が生じた場合でも、他の部分も含め前記分解によりボトル栓の全部品をお手入れでき、長期に清潔に保てる。   According to the single-open bottle of the present invention, if the bottle body is held so as to face the front side of the bottle body, the bottle body obstructs the direct drinking from the drinking mouth, and the single-open lid is close to the rear. Since the hinge connecting part is opened toward the rear side and does not disturb the direct drinking from the drinking port near the front part, it becomes easy to drink directly. In addition, when the bottle body is gripped from the side, the thumb of the hand is positioned at the front of the bottle body, and the opening operation on the front free end side of the one-side opening / closing lid can be easily performed. As it is, it is easy to drink directly with almost one movement in parallel or in parallel with the drinking mouth as it is, and the top surface is insulated by forming the heat insulation space and there is no condensation due to cold drinks, so you may be worried when leaning forward There is no problem of getting wet. Furthermore, even when condensed water is generated in the heat insulating space forming portion, all parts of the bottle stopper can be cleaned by the above decomposition including other portions, and can be kept clean for a long time.

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７に示す実施の形態に基づき詳細に説明する。しかし、以下の説明は本発明の具体例であって、特許請求の範囲の記載の内容を限定するものではない。   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. However, the following description is a specific example of the present invention, and does not limit the content of the claims.

本実施の形態の片開きボトルは図１の例、図６の例に示すように、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４を有し、シールパッキン１６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 the example of FIG. 1 and the example of FIG. 6, 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 an inner wall and an outer wall made of stainless steel. Made of synthetic resin, which is a bottle stopper that has a female screw 4 that is screwed into a male screw 3 formed on the outer wall of the mouth 1a of the vacuum double container 1 and is attached to the vacuum double container 1 via a seal packing 16. A bottle body 20 is formed by the stopper body 5. 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２６などによって代替することもできる。シールパッキン２６は開閉蓋７の天板７ａの裏面にい体成形した筒壁７ｂ内にボス部２６ａを圧入して着脱できるように装着してあり、シールパッキン２６や開閉蓋７の丸洗いを可能にしている。   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 26 having elasticity for sealing the drinking mouth 14 provided on the one-sided lid 7. You can also. The seal packing 26 is mounted so that the boss portion 26a can be press-fitted into and removed from the cylindrical wall 7b formed on the back surface of the top plate 7a of the opening / closing lid 7, and the seal packing 26 and the opening / closing lid 7 can be washed in a circle. I have to.

ここで、本実施の形態での栓体５は図１の例、図６の例に示すように、ボトル体１の口部１ａに前記雄ねじ３、雌ねじ４などによって着脱できるように装着される栓体５を有している。しかし、この着脱形式は部分ねじ構造、あるいは弾性を有してあるいは弾性を有しないで係脱し合う係合構造など、種々な方式を採用することができる。この栓体５は、ボトル体１の口部１ａ外側に前記ねじ構造などにて着脱できるように装着される部分となる外栓部２１と、この外栓部２１の内側に直飲みできる飲み口１４を有して着脱できるように組み合わされ、ボトル体１内には飲み口１４まわりのお手入れ用開放部２２ａを持った断熱空間形成部２２で臨んで通じ、かつ飲み口１４が外栓部２１上にその天板２１ｂの透孔２１ｄを通じ突出する中栓部２３と、これら外栓部２１、中栓部２３、およびボトル本体１の相互境界部にそれらいずれからも着脱できるように組み合わされて相互をシールし、少なくともこのシール状態で中栓部２３の前記お手入れ用開放部２２ａをシールするシール部材としての前記シールパッキン１６と、を備えている。   Here, as shown in the example of FIG. 1 and the example of FIG. 6, the stopper body 5 in this embodiment is attached to the mouth portion 1 a of the bottle body 1 so as to be detachable by the male screw 3, the female screw 4, and the like. It has a plug 5. However, this attachment / detachment method can employ various methods such as a partial screw structure, or an engagement structure that engages and disengages with or without elasticity. The plug body 5 includes an outer plug portion 21 that is a portion that is attached to the outside of the mouth portion 1 a of the bottle body 1 with the screw structure or the like, and a drinking mouth that can be directly taken inside the outer plug portion 21. 14, the bottle body 1 is detachably connected to the bottle body 1 through a heat insulating space forming portion 22 having a care opening portion 22a around the drinking mouth 14, and the drinking mouth 14 is an outer plug portion. 21 is combined with the outer plug portion 21, the inner plug portion 23, and the mutual boundary portion of the bottle body 1 so as to be detachable from both of them. And the seal packing 16 as a seal member for sealing at least the maintenance opening 22a of the inner plug portion 23 in this sealed state.

これにより、図１の例のボトル栓５および図６の例のボトル栓５のは、それぞれ、図２、図７に分解して示すように、ボトル体１の口部１ａに着脱できるように装着される栓体５の部品点数が、外栓部２１、中栓部２３、シールパッキン１６の３つと少なく、当然のに分解、組み立ての工数も同様に少なくなる。従って、安価に供せる上、簡単に組み立て、分解ができ、分解は、中栓部２３に形成したボトル栓５外面での結露を防止する断熱空間形成部２２の開放も併せなされるので、断熱空間形成部２２に結露水が生じることがあっても、その部分を含め全部品につきくまなく洗浄できるなど簡単にかつ十分にお手入れすることができ、長期に清潔に保てる。また、断熱空間形成部２２による断熱作用はボトル体１の保冷、保温効果も高める。   Accordingly, the bottle stopper 5 of the example of FIG. 1 and the bottle stopper 5 of the example of FIG. 6 can be attached to and detached from the mouth 1a of the bottle body 1 as shown in an exploded view in FIGS. The number of parts of the plug body 5 to be mounted is as small as three of the outer plug portion 21, the inner plug portion 23, and the seal packing 16, and naturally the man-hours for disassembly and assembly are similarly reduced. Therefore, the heat insulating space forming part 22 that prevents condensation on the outer surface of the bottle stopper 5 formed in the inner stopper part 23 is also combined, so that the heat insulating part 22 can be assembled and disassembled easily. Even if dew condensation water is generated in the space forming part 22, all parts including the part can be cleaned easily and sufficiently, and can be kept clean for a long time. Moreover, the heat insulation effect by the heat insulation space formation part 22 improves the cold insulation of the bottle body 1, and the heat insulation effect.

また、中栓部２３は外栓部２１の内側にその飲み口１４が図１、図３、および図６に示すように外栓部２１上に突出するように位置する組み合わせを満足して、外栓部２１をボトル体１の口部１ａに装着し、この装着に際してシールパッキン１６が外栓部２１、中栓部２３、およびボトル体１の口部１ａの相互境界部に、例えば図１、図６に示すように位置するようにしておくだけで、組立およびボトル体１の口部１ａへの装着ができ、同時に、外栓部２１、中栓部２３、およびボトル体１の口部１ａの相互境界部をシールするのに併せ、中栓部２３に有する断熱空間形成部２２のお手入れ用開放部２２ａをシールすることができる。さらに、外栓部２１をボトル体１の口部１ａから取り外すことによって中栓部２１およびシールパッキン１６が少なくとも露出するので着脱可能な相互を分解できる。従って、中栓部２３が外栓部２１の内側にその飲み口１４が外栓部２１上に突出するように位置する組み合わせと、外栓部２１をボトル体１の口部１ａに装着し、その際シールパッキン１６が外栓部２１、中栓部、２３およびボトル体１の口部１ａの相互境界部に位置させるだけで、組立およびボトル体１の口部１ａへの装着に加え、必要なシールを満足してシール不良などなく安全使用することができる。さらに、外栓部２１をボトル体１の口部１ａから取り外せば中栓部２３およびシールパッキン１６が少なくとも露出して着脱可能な相互を容易に分解できる。   Further, the inner plug portion 23 satisfies the combination in which the drinking mouth 14 is located on the inner side of the outer plug portion 21 so as to protrude on the outer plug portion 21 as shown in FIG. 1, FIG. 3, and FIG. The outer plug portion 21 is attached to the mouth portion 1a of the bottle body 1, and the seal packing 16 is attached to the mutual boundary portion of the outer plug portion 21, the inner plug portion 23, and the mouth portion 1a of the bottle body 1 at the time of attachment, for example, FIG. 6, it is possible to assemble and attach the bottle body 1 to the mouth portion 1a, and at the same time, the outer stopper portion 21, the inner stopper portion 23, and the mouth portion of the bottle body 1 can be mounted. In addition to sealing the mutual boundary portion of 1a, the opening portion 22a for maintenance of the heat insulating space forming portion 22 provided in the inner plug portion 23 can be sealed. Further, by removing the outer plug portion 21 from the mouth portion 1a of the bottle body 1, the inner plug portion 21 and the seal packing 16 are at least exposed, so that the removable parts can be disassembled. Accordingly, the combination in which the inner plug portion 23 is positioned inside the outer plug portion 21 so that the drinking port 14 protrudes on the outer plug portion 21 and the outer plug portion 21 are attached to the mouth portion 1a of the bottle body 1, At that time, the seal packing 16 is only required to be positioned at the mutual boundary between the outer plug portion 21, the inner plug portion 23, and the mouth portion 1a of the bottle body 1, and in addition to being assembled and mounted on the mouth portion 1a of the bottle body 1 Satisfactory seals can be used and it can be used safely with no seal failure. Further, when the outer plug portion 21 is removed from the mouth portion 1a of the bottle body 1, the inner plug portion 23 and the seal packing 16 are at least exposed and can be easily detached from each other.

また、断熱空間形成部２２は、図１、図２に示す例、図６、図７に示す例で共通して、図１、図２に示す例の飲み口１４の一部断面した図４で代表して示すように、飲み口１４周りの軸線方向に形成されて外周間をお手入れ用開放部２２ａとした二重壁２２ｂ、２２ｃが形成するようにしている。このように、断熱空間形成部２２が飲み口１４周りでその軸線方向に重なった二重壁２２ｂ、２２ｃよりなると、飲み口１４とと共に容易に一体成形されて、それら二重壁２２ｂ、２２ｃの外周間が図示するようにお手入れ用開放部２２ａをなし、しかも、このお手入れ用開放部２２ａが図１、図６に示すように、外栓部２１とボトル体１の口部１ａとの間をシールするシールパッキン１６の直近に位置するので、外栓部２１、中栓部２３、およびボトル体１の口部１ａの相互境界部をシールするシールパッキン１６を共用してお手入れ用開放２２ａをシールするのに好都合となる。つまり、断熱空間形成部２２が飲み口１４周りで軸線方向での二重壁２２ｂ、２２ｃで、その外周間がお手入れ用開放部２２ａとなって、外栓部２１とボトル体の口部との間をシールするシール部材直近に位置し、外栓部、中栓部、およびボトル体１の口部１ａの相互境界部をシールする１つのシールパッキン１６を共用してお手入れ用開放部２２ａをシールするのに、特に大きな断面域を必要とせずシールパッキン１６の材料費、成形費を含めコスト高にならない。   Further, the heat insulating space forming portion 22 is common to the examples shown in FIGS. 1 and 2 and the examples shown in FIGS. 6 and 7, and FIG. 4 is a partial cross-sectional view of the drinking mouth 14 of the example shown in FIGS. 1 and 2. As shown as a representative, double walls 22b and 22c formed in the axial direction around the drinking mouth 14 and having a cleaning opening 22a between the outer periphery are formed. Thus, if the heat insulation space formation part 22 consists of the double walls 22b and 22c which overlapped in the axial direction around the drinking mouth 14, it will be easily integrally formed with the drinking mouth 14, and these double walls 22b and 22c As shown in FIG. 1, the maintenance opening 22a is formed between the outer plug 21 and the mouth 1a of the bottle body 1 as shown in FIGS. Since it is located in the immediate vicinity of the seal packing 16 that seals the gap, the seal plug 16 that seals the mutual boundary between the outer plug portion 21, the inner plug portion 23, and the mouth portion 1 a of the bottle body 1 is shared and opened for maintenance. It is convenient to seal 22a. That is, the heat insulation space forming part 22 is the double walls 22b and 22c in the axial direction around the drinking mouth 14, and the outer periphery is an open part 22a for cleaning, and the outer plug part 21 and the mouth part of the bottle body Opening part 22a for maintenance by sharing one seal packing 16 that is located in the immediate vicinity of the sealing member that seals between and seals the outer plug part, the inner plug part, and the mutual boundary part of the mouth part 1a of the bottle body 1 In particular, a large cross-sectional area is not required to seal the seal, and the material cost and molding cost of the seal packing 16 are not increased.

しかも、このシールパッキン１６は、図１、図２に示す例、図６、図７に示す例で共通して、図１、図２に示す例の飲み口１４の一部断面した図４で代表して示すように、断熱空間形成部２２のお手入れ用開放部２２に着脱できるように装着されてそのお手入れ開放部２２ａをシールするようにしている。これにより、シールパッキン１６が中栓部２３の断熱空間形成部２２のお手入れ用開放部２２ａに着脱できるように装着されることで、お手入れ用開放部２２のシールを保証し、かつ、シールパッキン１６の図２、図７に示し、図５で代表して示す取り外しにより開放する断熱空間形成部２２のお手入れ用開放部２２ａを通じたお手入れを可能としながら、中栓部２３と外栓部２１との組み合わせによってシールパッキン１６が外栓部２１、中栓部、およびボトル体１の口部１ａの相互境界部をシールする位置に一義的に位置決めされて、人為的な位置決めが不要となる。つまり、シールパッキン１６が、中栓部２３の断熱空間形成部２２のお手入れ用開放部２２ａに装着されて、お手入れ用開放部２２ａのシールを保証しながら、その取り外しにて断熱空間形成部２２のお手入れ用開放２２ａ部を通じ洗浄や拭き取りといったお手入れできるようにし、中栓部２３と外栓部２１との組み合わせによってシールパッキン１６が外栓部２１、中栓部２３、およびボトル体１の口部１ａ間の必要シール位置に特別な手間なく的確に位置決めされ確実にシールすることができる。   Moreover, this seal packing 16 is common to the examples shown in FIGS. 1 and 2 and the examples shown in FIGS. 6 and 7, and is a partial cross-sectional view of the drinking mouth 14 of the example shown in FIGS. As representatively shown, the heat insulation space forming portion 22 is detachably attached to the care opening portion 22 so as to seal the care opening portion 22a. As a result, the seal packing 16 is mounted so as to be detachable from the care opening portion 22a of the heat insulation space forming portion 22 of the inner plug portion 23, so that the seal of the care opening portion 22 is guaranteed and the seal The inside plug portion 23 and the outer plug are made possible through the maintenance opening portion 22a of the heat insulation space forming portion 22 that is opened by the removal of the packing 16 shown in FIGS. The seal packing 16 is uniquely positioned by the combination with the portion 21 so as to seal the mutual plug portion of the outer plug portion 21, the inner plug portion, and the mouth portion 1a of the bottle body 1, so that artificial positioning is unnecessary. Become. That is, the seal packing 16 is attached to the care opening portion 22a of the heat insulation space forming portion 22 of the inner plug portion 23, and the heat insulation space forming portion is secured by removing the seal packing 16 while ensuring the seal of the care opening portion 22a. 22 can be cleaned and wiped off through the opening 22a for cleaning. The combination of the inner plug portion 23 and the outer plug portion 21 makes the seal packing 16 the outer plug portion 21, the inner plug portion 23, and the bottle body 1. It is possible to accurately position and seal the required sealing position between the mouth portions 1a without any special effort.

さらに、中栓部２１は、図１、図２に示す例、図６、図７に示す例で共通して、シールパッキン１６を介してボトル体１の口部１ａに上方から着座し、外栓部２１は、ボトル本体１への装着によってシールをパッキン１６を介し中栓部２３を前記着座状態に押圧するものとしてある。このように、中栓部２３がシールパッキン１６を介してボトル体１の口部１ａに上方から着座した状態で、外栓部２１がボトル本体１への装着によってシールパッキン１６を介して前記着座状態に押圧されることで、中栓部２３はボトル本体１の口部１ａとの嵌め合いのない着座だけの簡単な組み合わせで、ボトル本体１の口部１ａと外栓部２１との間に、中栓部２３の断熱空間形成部２２が心材となって確固に挟み付けられるので、外栓部２１、中栓部２３、およびボトル体１の口部１ａの相互境界部のシールがより確実に達成される。従って、中栓部２３が外栓部２１との組み合わせ上、シールパッキン１６を介して、着座しただけのボトル本体１の口部１ａとそれに装着した外栓部２１との間に、自身の断熱空間形成部２２が心材となって確固に挟み付けられて、外栓部２１、中栓部２３、およびボトル体１の口部１ａの相互境界部のシールがより確実に達成されるのに併せ。組み立て、装着の状態が安定する。   Further, the inner stopper portion 21 is commonly seated on the mouth portion 1a of the bottle body 1 via the seal packing 16 from the upper side in common with the examples shown in FIGS. 1 and 2 and the examples shown in FIGS. The stopper 21 presses the inner stopper 23 into the seated state through the packing 16 when the stopper 21 is attached to the bottle body 1. In this way, with the inner plug portion 23 seated from above on the mouth portion 1 a of the bottle body 1 via the seal packing 16, the outer plug portion 21 is attached to the bottle main body 1 through the seal packing 16 and the seating is performed. By being pressed to the state, the inner plug portion 23 is a simple combination of only sitting without fitting with the mouth portion 1a of the bottle body 1, and between the mouth portion 1a of the bottle body 1 and the outer stopper portion 21. Since the heat insulating space forming part 22 of the inner plug part 23 is firmly sandwiched as a core material, the sealing of the mutual boundary part of the outer plug part 21, the inner plug part 23, and the mouth part 1a of the bottle body 1 is more reliable. To be achieved. Therefore, the combination of the inner plug portion 23 with the outer plug portion 21, between the mouth portion 1 a of the bottle body 1 just seated through the seal packing 16 and the outer plug portion 21 attached thereto, In addition to the space forming portion 22 being firmly sandwiched as a core material, the sealing of the outer plug portion 21, the inner plug portion 23, and the mutual boundary portion of the mouth portion 1a of the bottle body 1 is more reliably achieved. . Assembling and mounting are stable.

しかも、中栓部２３の口部１ａへ着座してのシール保証は、中栓部２３の口部１ａ内周への嵌め合いを不要として、嵌め合いにより口部１ａを塞がない分だけボトル体１の実容量を高められる。   In addition, the seal guarantee when seated on the mouth portion 1a of the inner plug portion 23 does not require the fitting of the inner plug portion 23 to the inner periphery of the mouth portion 1a, and the bottle does not block the mouth portion 1a by fitting. The actual capacity of the body 1 can be increased.

さらに具体的には、二重壁２２ｂ、２２ｃの径は一方が他方より小さく、径の大きな例えば上側の壁２２ｂの外周のシールパッキン１６の溝部１６ａが外方から弾性的に被さって装着され、この装着部分１６ｂが壁２２ｂを心材として外栓部２１とボトル体１の口部１ａとの間で挟み付けられる部分として十分なシール圧を確保しながら、二重壁２２ｂ、２２ｃ共に挟み付けて破損の原因となるのを防止している。径の小さな例えば下側の壁２２ｃは単純に外周にシールパッキン１６のＬ型断面で内向きのシールリップ１６ｃを側方および外面、具体的には下面から弾性的に当接してシールするようにしてあり、シールパッキン１６の断面形状の単純化を図り成形性を高めている。シールパッキン１６は、また、前記シールリップの側面から外周に延びて前記装着部分１６ｂとの間に隙間１６ｄを有した補助リップ１６ｅを一体成形することで、前記外栓部２１とボトル体１の口部１ａとの間の挟み付け部に、これら隙間１６ｄ、補助リップ１６ｅが介在することで、中空部などの複雑な断面部を持たずに、補助リップ１６ｅの隙間１６ｄを利用した柔軟性を前記挟み付け部に付与して、外栓部とボトル体１の口部１ａとの間の成形誤差、組み立て誤差を吸収したより確実で無理のないシールが達成されるようにしてある。   More specifically, one of the double walls 22b and 22c has a smaller diameter than the other, and the groove 16a of the seal packing 16 on the outer periphery of the upper wall 22b, for example, has a larger diameter and is elastically covered from the outside. The mounting portion 16b is sandwiched between the double walls 22b and 22c while securing a sufficient sealing pressure as a portion to be sandwiched between the outer plug portion 21 and the mouth portion 1a of the bottle body 1 with the wall 22b as a core material. Preventing damage. For example, the lower wall 22c having a small diameter simply seals an inward seal lip 16c with an L-shaped cross section of the seal packing 16 on the outer periphery from the side and outer surfaces, specifically from the lower surface. Therefore, the cross-sectional shape of the seal packing 16 is simplified to improve the moldability. The seal packing 16 is also integrally formed with an auxiliary lip 16e extending from the side surface of the seal lip to the outer periphery and having a gap 16d with the mounting portion 16b. By interposing the gap 16d and the auxiliary lip 16e in the sandwiched portion between the mouth 1a, the flexibility using the gap 16d of the auxiliary lip 16e can be achieved without having a complicated cross section such as a hollow portion. It is applied to the sandwiching portion to achieve a more reliable and reasonable seal that absorbs molding errors and assembly errors between the outer plug portion and the mouth portion 1a of the bottle body 1.

しかも、補助リップ１６ｅ、装着部分１６ｂに対向するボトル体１の口部１ａの上端は、真空二重容器を構成するステンレス製の内筒と外筒との口部同士をＴＬＧ溶接などで接合した二重壁端部としてあり、前記挟み付けによる補助リップ１６ｅおよび装着部１６ｂ下面への無理のない食い込みを助長してシール性を高め、外栓部２１の装着部分１６ｂとの対向部は鉤型面２１ａとして装着部分１６ｂの外周を受けながら上方から口部１ａの二重壁幅をその内外に超える面域で圧着して、中栓部２３との間のシールはもとより、その圧着によるボトル体１の口部１ａの補助リップ１６ｅおよび装着部分１６ｂへの食い込みを伴う中栓部２３および口部１ａ間のシール性を高められる。また、装着部分１６ｂは上部の壁２２ｂの外周に少しの隙間１６ｆを残すように装着されて、柔軟変形部をなすことで、外栓部２１の鉤型面２１ａ内周との初期嵌合を軽減ないしは隙間を持たせながら、鉤型面２１ａで装着部分１６ｂを上方から圧着して行くときの装着部分１６ｂの外形の広がりによって鉤型面２１ａへの密着度を高めて、外栓部２１と中栓部２３との間のシール性をさらに高められるようになっている。また、補助リップ１６ｅはＬ型のリップ１６ｃが下側の壁２２ｃの外周から外方に逃げる変形を抑えるので、簡単な当接関係によって、内部空気の外部空気との対流などによる入れ替わりが損なわれる程度のシール不良は回避できる。保冷時の内圧低下などでそれが損なわれるような場合はそれに打ち勝つ当接状態、嵌合状態を確保する構造とすればよい。図４に示す例ではＬ型のリップ１６ｃには、その下側の壁２２ｃに圧接するリップ片１６ｃ１と補助リップ１６ｅ形成部との間に薄肉部１６ｇを設けて弾性を弱め、リップ片１６ｃ１が壁２２ｃの下面に馴染みよく圧接して相互の対向面間に隙間ができにくくシール性が高まる工夫をしている。   Moreover, the upper end of the mouth portion 1a of the bottle body 1 facing the auxiliary lip 16e and the mounting portion 16b is joined by TLG welding or the like between the mouth portions of the stainless steel inner cylinder and the outer cylinder constituting the vacuum double container. It is a double wall end portion, promotes easy biting into the lower surface of the auxiliary lip 16e and the mounting portion 16b by the pinching and enhances the sealing performance, and the portion facing the mounting portion 16b of the outer plug portion 21 is a saddle type While receiving the outer periphery of the mounting portion 16b as the surface 21a, it is pressure-bonded from above at the surface area exceeding the double wall width of the mouth portion 1a inside and outside, and the bottle body by the pressure bonding as well as the seal with the inner plug portion 23 The sealing performance between the inner plug portion 23 and the mouth portion 1a with biting into the auxiliary lip 16e and the mounting portion 16b of the mouth portion 1a can be enhanced. Further, the mounting portion 16b is mounted so as to leave a small gap 16f on the outer periphery of the upper wall 22b, and by making a flexible deformation portion, an initial fitting with the inner periphery of the bowl surface 21a of the outer plug portion 21 is achieved. The degree of adhesion to the hook surface 21a is increased by the expansion of the outer shape of the mounting portion 16b when the mounting portion 16b is pressure-bonded from above with the hook surface 21a while reducing or providing a gap. The sealing property between the inner plug portion 23 can be further enhanced. Further, since the auxiliary lip 16e suppresses the deformation of the L-shaped lip 16c escaping outward from the outer periphery of the lower wall 22c, the exchange of the internal air due to convection with the external air is impaired by a simple contact relationship. A degree of sealing failure can be avoided. In the case where it is damaged due to a decrease in the internal pressure during cold insulation, a structure that ensures a contact state and a fitted state that overcomes it may be used. In the example shown in FIG. 4, the L-shaped lip 16c is provided with a thin wall portion 16g between the lip piece 16c1 and the auxiliary lip 16e forming portion pressed against the lower wall 22c to weaken the elasticity. The device is devised so as to improve the sealing performance by making a close contact with the lower surface of the wall 22c so that a gap is not formed between the opposing surfaces.

また、図１、図２に示す例、図６、図７に示す例で共通して、さらに、断熱空間形成部２２と外栓部２１の天板２１ｂとの間にも相互間のシールパッキン１６によるシール状態にて密閉空間３１が形成されるようにしてあり、この密閉空間３１および断熱空間形成部２２によって二重の断熱構造をなして、保冷飲料による外栓部２１の天板２１ｃの外面への結露をより確実に防止するのに併せ、保冷、保温効果もさらに高められる。これら、結露防止、保冷、保温のためには、飲み口１４を除くできるだけ多くの面域にかつ抜けなく、断熱空間形成部２２や密閉空間３１を設けるのが好適である。このため、図示例では成形によういな直立型の飲み口１４を直飲みしやすくするために断熱空間形成部２２の前部一杯まで寄せてあって、前部側で断熱空間が形成されない構成となっているのを、断熱空間が飲み口１４の周りにドーナツ型に連続するようにすることができる。   Further, in common with the examples shown in FIGS. 1 and 2 and the examples shown in FIGS. 6 and 7, the seal packing is also provided between the heat insulating space forming part 22 and the top plate 21 b of the outer plug part 21. The sealed space 31 is formed in a sealed state by 16, and a double heat insulating structure is formed by the sealed space 31 and the heat insulating space forming portion 22, and the top plate 21c of the outer plug portion 21 by the cold beverage is formed. In addition to more reliably preventing dew condensation on the outer surface, the effect of cold insulation and heat insulation is further enhanced. In order to prevent condensation, cool, and keep warm, it is preferable to provide the heat insulating space forming portion 22 and the sealed space 31 in as many surface areas as possible except the drinking mouth 14 without falling out. For this reason, in the illustrated example, in order to make it easy to directly drink the upright type drinking mouth 14 like molding, the heat insulation space forming part 22 is brought to the front part and the heat insulation space is not formed on the front part side. The heat insulation space can be made continuous in a donut shape around the drinking mouth 14.

以上のようなボトル栓２０を、図１の例、図２の例のようにボトル体１の口部１ａに装着した片開きボトル２０は、ボトル体１の口部１ａに装着したボトル栓５の飲み口１４が前部寄りに位置しているので、ボトル体１を前部と向かい合うように把持すれば、飲み口１４がボトル体１の胴部１ｂよりも前部側、つまり自身の口側に寄って位置するので、直飲みするのにボトル体１が邪魔にならない。従って、用途に応じた容量を確保して、しかも、ボトル体１の径に左右されないで直飲みしやすくなる。また、片開きの開閉蓋７は開かれるとボトル栓５の後部寄りとなるヒンジ連結部１０側に立ち上がるので、前部寄りの飲み口１４からの直飲みを邪魔しないし、ボトル体１を側方から把持した手の親指がボトル体１の、ロック機構８を有して開閉蓋７を開き操作することになる前部に位置して、開き操作するのと同時にボトル体１の前傾を伴いまたはそのまま飲み口１４を自身の口に近付けて直飲みでき、前傾させても外栓部２１の天面は断熱空間形成部２２および密閉空間３１が断熱空間となっていることにより、保冷飲料による結露が生じないし、保冷、保温効果の高いものとなる。さらに、断熱空間形成部２２内に結露水が生じた場合でも、前記分解によりボトル栓５の全部品を洗浄や拭き取りなどのお手入れができ、長期に清潔に保てる。   A single-open bottle 20 in which the bottle stopper 20 as described above is attached to the mouth portion 1a of the bottle body 1 as in the example of FIG. 1 and FIG. 2 is the bottle stopper 5 attached to the mouth portion 1a of the bottle body 1. Since the drinking mouth 14 of the bottle body 1 is positioned closer to the front, if the bottle body 1 is gripped so as to face the front, the drinking mouth 14 is on the front side of the body 1b of the bottle body 1, that is, its own mouth. Since it is located close to the side, the bottle body 1 does not get in the way to drink directly. Therefore, it becomes easy to drink directly without securing the capacity | capacitance according to a use and being influenced by the diameter of the bottle body 1. FIG. Further, when the one-side opening / closing lid 7 is opened, it rises to the hinge connecting part 10 side near the rear part of the bottle stopper 5, so that direct drinking from the drinking mouth 14 near the front part is not disturbed, and the bottle body 1 is moved sideways. The thumb of the hand gripped from the side is located at the front part of the bottle body 1 which has the lock mechanism 8 and opens and closes the opening / closing lid 7, and at the same time the bottle body 1 is tilted forward. Along with or as it is, the drinking mouth 14 can be directly brought close to its own mouth, and even if it is tilted forward, the top surface of the outer plug portion 21 is insulated from the heat insulating space forming portion 22 and the sealed space 31 so that it is kept cool. Condensation due to beverages does not occur, and the effect of cooling and keeping warm is high. Furthermore, even when condensed water is generated in the heat insulating space forming portion 22, all parts of the bottle stopper 5 can be cleaned and wiped off by the above-described decomposition, and can be kept clean for a long time.

ロック機構８は図１、図６に示すように、開閉蓋７と係合して閉じ状態に係止するフック部を持ったロック部材３２とこのロック部材３２の開閉蓋７との係合を外して閉じ位置へのロックを解除するロック解除片３３を同軸３４にて枢支し、外栓部２１とロック部材３２との間に働かせたばね３５により、ロック部材３２をロック位置に、ロック解除片３３をロック解除操作開始位置に安定させ、開閉蓋７が閉じられるとロック部材３２がばね３５に抗してロック解除片３３との間に設けた遊びを利用して単独に一旦ロック解除操作片３３の側に押し退けられるように退避し、開閉蓋７をフック部に受け入れて後、ばね３５の付勢によって復帰させられて開閉蓋７に係合して自動ロックするようになっている。一方、ロック解除片３３は押動するとロック部材３２をばね３５に抗して退避させ、開閉蓋７との係合を外してロックを解除するので開閉蓋７がばね１３１の付勢により自動的に開かれるようにしている。なお、ロック解除片３３はロック部材３２上で、外栓部２１との間でロック解除操作を邪魔される位置と邪魔されない位置とに移動できるようにし、解除操作を邪魔される位置に自動復帰するようにして不用意なロック解除操作を防止するようにしてある。   As shown in FIGS. 1 and 6, the lock mechanism 8 engages the lock member 32 having a hook portion that engages with the open / close lid 7 and is locked in a closed state, and the lock member 32 engages with the open / close lid 7. A lock release piece 33 for releasing and releasing the lock to the closed position is pivotally supported on the same axis 34, and the lock member 32 is brought into the lock position by the spring 35 which is operated between the outer plug portion 21 and the lock member 32. When the piece 33 is stabilized at the unlocking operation start position and the open / close lid 7 is closed, the locking member 32 resists the spring 35 and uses the play provided between the unlocking piece 33 and the unlocking operation once. It retracts so as to be pushed away to the side of the piece 33, and after the opening / closing lid 7 is received in the hook portion, it is returned by the urging force of the spring 35 and is engaged with the opening / closing lid 7 to be automatically locked. On the other hand, when the lock release piece 33 is pushed, the lock member 32 is retracted against the spring 35 and is disengaged from the open / close lid 7 to release the lock. To be opened. The unlocking piece 33 can be moved on the lock member 32 to a position where the unlocking operation is disturbed and unobstructed between the outer plug portion 21 and automatically returns to the position where the unlocking operation is disturbed. In this way, an inadvertent unlocking operation is prevented.

図６、図７に示す例では、さらに、断熱空間形成部２２は、飲み口１４と、シールパッキン１６による外栓部２１、中栓部２３、ボトル体１の相互、およびお手入れ用開放部２２ａのシール域と、の間に、外栓部２３外からボトル体１内への吸気路４１を有し、シールパッキン１６は、その吸気路４１の少なくとも外部開口部４１ａを有し、外栓部２１に設けた飲み口１４に対する開閉蓋７が閉じられたときに、開閉蓋７の一部、具体的には開閉蓋７の一部に突片状に一体成形するなどした閉じ部４２によって閉じられるようにしている。これにより、直飲み中の飲み口１４から外れた位置の吸気路４１を通じ外気をボトル体１内に自然吸気することができるし、吸気路４１が外栓部２１、中栓部２３、ボトル体１の相互、およびお手入用開放部２２ａのシール域よりも内側に位置するので、それらのシールを損なったりシール構造を複雑にすることはない。また、吸気路４１の少なくとも外部開口部４１ａをシールパッキン１６が弾性を有して形成することで、開閉蓋７を閉じるのと同時にその一部である閉じ部４２によって無理なく確実に閉じられる。この結果、直飲みに際し、飲み口１４から外れた位置の吸気路４１を通じ外気をボトル体１内に自然吸気するので、飲み口１４内での吸気時のような特別な吸気調整なく飲料をスムーズに流出させられるし、吸気路４１が必要シール域の内側にあってシールを損なったりシール構造を複雑にしたりしないので、機能不全や、コスト上昇の原因にはならない。また、吸気路４１の少なくとも外部開口部４１ａが弾性を有するシールパッキン１６よりなり、開閉蓋７を閉じるのと同時にその一部である閉じ部４２によって無理なく確実に閉じられる。   In the examples shown in FIGS. 6 and 7, the heat insulation space forming part 22 is further provided with a drinking mouth 14, an outer stopper part 21, an inner stopper part 23, a bottle body 1, and an opening part for maintenance. 22a has a suction path 41 from the outside of the outer plug portion 23 into the bottle body 1, and the seal packing 16 has at least an external opening 41a of the suction path 41. When the opening / closing lid 7 with respect to the drinking mouth 14 provided in the portion 21 is closed, the closing portion 42 is formed integrally with a part of the opening / closing lid 7, specifically, a part of the opening / closing lid 7 in a protruding shape. It is designed to be closed. As a result, the outside air can be naturally sucked into the bottle body 1 through the intake passage 41 at a position away from the drinking mouth 14 during direct drinking, and the intake passage 41 has the outer plug portion 21, the inner plug portion 23, and the bottle body. Since they are located on the inner side of the seal area of the one and the opening part 22a for care, the seals are not damaged or the seal structure is not complicated. Further, at least the external opening 41a of the intake passage 41 is formed by the seal packing 16 having elasticity, so that the opening / closing lid 7 is closed at the same time by the closing portion 42 as a part thereof without difficulty. As a result, since the outside air is naturally aspirated into the bottle body 1 through the intake passage 41 at a position away from the mouth 14 during direct drinking, the beverage can be smoothly smoothed without special inhalation adjustment as during inhalation in the mouth 14. Since the intake passage 41 is inside the necessary seal area and does not damage the seal or complicate the seal structure, it does not cause malfunction or increase in cost. In addition, at least the external opening 41a of the intake passage 41 is made of elastic seal packing 16, and at the same time as the opening / closing lid 7 is closed, it is reliably closed by the closing portion 42 which is a part thereof.

なお、図示例では吸気路４１は、二重壁２２ｂ、２２ｃに一体成形して壁２２ｃにてボトル体１内に開口し、外栓部２１上にその透孔２１ｃを通じ突出するようにしてあり、この吸気路４１の壁２２ｂからの突出部にシールパッキン１６に一体に形成した筒状カバーブ１６ｈを上方から被せて前記外部開口部４１ａを形成するようにしてある。そしてこの筒状カバーブ１６ｈが外栓部２１の天板２１ｂの透孔２１ｃを貫通する部分には透孔２１ｃの開口縁に下方より受けられる沈み止めリブ１６ｉを有し、外部開口部４１ａが開閉蓋７の閉じ部４２によって閉じられるときの下方への逃げを防止し、吸気路４１の上端との成形不良、組み立て不良による隙間があってもシール圧を確保できるようにしている。   In the illustrated example, the intake passage 41 is formed integrally with the double walls 22b and 22c, opens into the bottle body 1 through the wall 22c, and protrudes through the through hole 21c on the outer plug portion 21. The projecting portion from the wall 22b of the intake passage 41 is covered with a cylindrical cover 16h formed integrally with the seal packing 16 from above to form the external opening 41a. A portion of the cylindrical cover 16h that passes through the through hole 21c of the top plate 21b of the outer plug portion 21 has a settling stop rib 16i received from below at the opening edge of the through hole 21c, and the external opening 41a is opened and closed. A downward escape when the lid 7 is closed by the closing portion 42 is prevented, and a seal pressure can be secured even if there is a gap due to molding failure or assembly failure with the upper end of the intake passage 41.
