【本発明が解決しようとする課題】
上述したように、従来から原料等を分離して付属させ、飲用に際して原料等を飲料水等の液体と混合して飲用に供する飲料容器が種々開発され、実用にも供されている。しかし、従来の例えば特許文献１の如く缶状容器の開口部に複数の独立した小容器を設けたり、或いは特許文献２のようにラミネート紙パック等による箱形容器の上面（蓋部分）の内部側に、外部からストローを差し通して破ることのできる小容器を設けること、特許文献３の如く金属製缶状容器の蓋部分の裏側（内部）に破断具を備えた小容器を取り付けたり、特許文献４のようにカップ容器の中心部であって蓋板の裏側に取り付けた内筒部を設置して２室に区画すること、特許文献５のようにビン型容器の口部近傍又は底部近傍の位置に別室を用意し、且つビン型容器と連通する毛細管を設けること、又は特許文献６，７のようにビン型容器の口部内に封止した小容器を設置し、飲用に際して、キャップに用意した突起で前記小容器を破断する等々の構成は、それぞれ製作が不可能とは言わないまでも、製造工程や組み立て工程に多くの手数がかかるほか、付属容器に原料等を収納させて付属させる作業が面倒であり、長期間飲料中身の品質を保証して安価に提供するには種々な問題があると認められる。
【０００９】
本発明の目的は、容器の構造が至極簡単で製作が容易であり、その材質が所謂ペットボトル（ポリエチレンテレフタレートボトル）等のプラスチック系素材、鉄系或いはアルミニウム系の缶、或いは紙容器、ガラス容器等の別を問わず実施でき、付属容器との組み合わせもワンタッチ的に簡単に行え、長期間飲料中身の品質、鮮度、風味などを保証して安価に提供することができる飲料容器を提供することである。
本発明の次の目的は、飲料中身がお茶、コーヒー、乳製品、果汁等のジュース類、アルコール類等の別を問わず実施でき、また、それらの原料、添加物等が液体又は粉体、固形体、顆粒状であるかの形体の別を問わず容易に実施可能な飲料容器を提供することである。
【００１０】
【課題を解決するための手段】
上述した従来技術の課題を解決するための手段として、請求項１に記載した発明に係る原料等を分離して付属させた飲料容器は、
飲料水等の液体を収納する容器本体と、前記液体と混合して目的の飲料を作る原料等を収納する付属容器との組み合わせから成り、
容器本体の頭部又は下底部に、周面にネジを有する口部及び同口部の開口を封鎖した開封用シート部が形成されており、
付属容器には、前記容器本体の口部のネジに結合されるネジを周面に有する口部が形成され、当該口部の内側に、容器本体の液体と混合して目的の飲料を作る原料等を収納する容室が形成されており、更に容器本体の前記口部の開口を封鎖した開封用シート部を破る開封具を備えており、
付属容器は、その口部を容器本体の頭部又は下底部の口部とネジ結合して容器本体の頭部又は下部に付属されていることを特徴とする。
【００１１】
請求項２に記載した発明は、請求項１に記載した原料等を分離して付属させた飲料容器において、
容器本体と付属容器とは両者の当接部が開封紐を介して一体的に接合されており、容器本体と付属容器との組み合わせ状態が、ペットボトル等既存容器の規格化された形状、寸法等の条件を満たす構成であることを特徴とする。
【００１２】
請求項３に記載した発明は、請求項１に記載した原料等を分離して付属させた飲料容器において、
容器本体の頭部又は下底部の口部の開口を封鎖した開封用シート部には、開封具による開封を促進する破断誘導処理が行われており、付属容器の容室に収納された原料等は不活性ガス等の注入・充填により不活性雰囲気を保持して容器本体に付属されることを特徴とする。
【００１３】
請求項４に記載した発明は、請求項１に記載した原料等を分離して付属させた飲料容器において、
付属容器の容室に収納される原料等は、液体又は粉末状若しくは顆粒状、粒状、ブロック状その他の固形状であることを特徴とする。
【００１４】
【発明の実施形態】
以下に、請求項１〜４に記載した発明に係る、原料等を分離して付属させた飲料容器の実施形態を、図面に基いて説明する。
先ず図１〜図６は、原料等が粉ミルク、粉コーヒー等の粉体である場合の実施形態を示す。この飲料容器は、飲料水等の液体１を収納する容器本体２と、前記液体１と混合して目的の飲料を作る原料等３を収納する付属容器４との組み合わせで構成されている。図１〜図６はまた、容器本体２および付属容器４がいわゆるペットボトルとして知られた形態のプラスチック系ビン形容器であることを示しているが、これに限るものではない。
容器本体２は、その上端部に通例のペットボトルと同様にキャップ５を着脱可能で、中身の飲料を飲むための口部６を有するが、下底部にも、外周面にネジ７を有する口部８を有している。そして、前記口部８の開口を水密的に完全封鎖した全体として薄肉の開封用シート部９が、必要により破断して開封可能な構成で形成されている。この開封用シート部９には、図３に例示したように、後述する開封具による開封を促進する、例えば破断容易な切り込み溝の如き破断誘導処理９ａの加工が、図３の如く十字形に、或いは渦巻き形その他に行われている（請求項３に記載した発明）。
【００１５】
一方、付属容器４は、全体として前記容器本体２の底部の一部を形成する形態とされている。付属容器４には、前記容器本体２の下底部の口部８のネジ７と結合されるネジを内周面に有する口部１０が形成され、当該口部１０の内側に、容器本体２の液体１と混合して目的の飲料を作る原料等３を収納する容室１１が形成されている。そして、容室１１の底壁から立ち上がる突起状に、容器本体２の前記口部８の開口を封鎖した開封用シート部９を突き破る開封具１２が設けられている。この開封具１２は、非飲用時には容器本体２の前記口部８の開口を封鎖した開封用シート部９には決して当たらない高さである。一方、飲用に際して付属容器４の口部１０を強くねじ込むと、開封具１２は、前記開封用シート部９を、粉状の原料等３が通過する（こぼれ落ちる）のに必要充分な状態に破断できる高さと形状に形成されている。付属容器４の容室１１を形成する上面壁１１ａは、図５のように当該容器を逆さに倒立させて容器本体２の前記口部８の開口を封鎖した開封用シート部９を破断した際、粉状の原料等３がサラサラと滞留することなく破断箇所から下方の液体１へスムーズにこぼれ落ちるように、同粉体の安息角以上の傾斜面に形成されている。但し、原料等３が液体又は粒状、顆粒状等の場合、前記上面壁１１ａの傾斜角度は必ずしも必要でない。
【００１６】
上記構成の付属容器４は、その口部１０を容器本体２の下底部の口部８とネジ結合して容器本体２の下部に付属される。但し、付属容器４の容室１１内へは、予め所定の原料等３を入れて収納せしめる。更にその上に当該原料等３の品質、鮮度、風味などを長期にわたり安全に保ち温度差による圧力変化が少ない不活性ガス１６（窒素ガス、ヘリウムガス、アルゴンガス、二酸化炭素、亜酸化窒素など）を注入・充填して不活性雰囲気を保持させる（請求項３に記載した発明）。
或いは粉状の原料等３を、少し圧力を加えた不活性ガス１６と共に容室１１内へ混入させ高圧状態に充填する方法も実施できる。不活性ガス１６は空気よりも質量が大きく自然放出が少ないので、容室１１内へ注入した状態はそのまま自然に保たれる。よって、そのまま付属容器４の口部１０を容器本体２の下底部の口部８とネジ結合して容器本体２の下部に付属させることができ、簡単な取り扱いと処理ができる。前記のとおりであるから、容室１１の容量は、容器本体２に収納された液体１の量と原料等３を混合して飲料となし得る収容量の大きさに形成される。
【００１７】
なお、付属容器４には、上記のようにして容器本体２の下底部に付属させた場合に、容器本体２の胴部と一連の胴を形成する繋ぎ胴部１３が上向きのスカート状に形成されている。そして、上記したように原料等３を収納させた付属容器４を容器本体２の下底部に付属させたときは、更に容器本体２の胴部と一連の胴を形成する繋ぎ胴部１３とを幅２ｍｍ〜５ｍｍ程度に細幅の開封紐１５を介して一体的に接合する（請求項２に記載した発明。）。そのため付属容器４は、開封紐１５を解除して取り除かないかぎり、容器本体２に対して回転することは不可能であり、よって容器本体２の下底部の口部８を封鎖した開封用シート部９を開封具１２で不用意に突き破る事故も決して発生しない。そして、当該飲料容器を外部から見た形態は、開封紐１５の存在は視認されるけれども、付属容器４は容器本体２と一体化してその存在感を視認させず、全体として１個のビン形容器の意匠を呈する。そこで、本発明の飲料容器は、容器本体２と付属容器４とを上記のように組み合わせ状態において、既に市販されているペットボトル等の既存容器の規格化された形状、寸法等の条件を満たす構成とし、既存の自動販売機やショーケースで共通に販売可能な構成とすることができる（請求項２に記載した発明）。
【００１８】
本発明の飲料容器は、上記のように構成され使用されるから、中身飲料の飲用に際しては、先ず当該飲料容器を図４のように逆さの向きに倒立させて持つ。そして、先ず開封紐１５を引き剥がして取り除く。すると容器本体２の胴部下端と付属容器４の繋ぎ胴部１３との間に少なくとも開封紐１５の幅寸相当の隙間Ｓが発生し、付属容器４は回転可能になる。そこで容器本体２に対して付属容器４を回転して、容器本体２の下底部の口部８のネジ７と結合された付属容器４の口部１０のネジ結合を図５のように押し進める。すると付属容器４の開封具１２が前進して容器本体２の下底部の口部８を封鎖した開封用シート部９を図６に概念図を示したように突き破り開封させる。したがって、付属容器４の容室１１に収納された粉状の原料等３は、破断された隙間からサラサラと速やかに容器本体２の方へこぼれ落ち、同容器本体２内に収納された液体１の中へ落下・混入してゆく。よって当該飲料容器をそのままよく振って原料等３と液体１との混合を充分に進め飲料となす。その後は、当該飲料容器を再び図１、図２のように本来の正常な立ち姿に戻し、キャップ５をあけて中身を飲用に供することになる。
原料等３は、飲用に供する直前まで、液体１とは分離独立した付属容器４内に不活性ガス雰囲気中で収納・保存され、紫外線などによる酸化、劣化、腐敗、変色なども防止されているので、長期にわたりその品質、風味、味わい、鮮度などが保持され、何時でも新鮮でおいしい飲料を提供できる。液体１が飲料水の場合でも、２年〜３年の賞味期限を保証できる。
【００１９】
なお、図７と図８には、付属容器４の繋ぎ胴部１３と、容器本体２の胴部下端とが一連の胴を形成するように細幅の開封紐１５を介して一体的に接合される構造の異なる実施形態を示している。
先ず図７の場合は、容器本体２の下底面部に、胴部よりも少し小径の筒状をなし、外周面にネジ１７を形成した接合筒部１８が下向きに突き出されている。一方、付属容器４の繋ぎ胴部１３の上端部には、内周面に前記接合筒部１８のネジ１７へ結合できる雌ネジを形成した接合筒部１９を設け、双方の接合筒部１８と１９をネジ結合する構成である。前記のようにネジ結合した上で、付属容器４の繋ぎ胴部１３と容器本体２の胴部下端とが細幅の開封紐１５を介して一体的に接合されている。この場合、前記のネジ１７は、口部８のネジ７と同一のピッチで形成されている。この構成によれば、容器本体２と付属容器４との一体性がより安定な状態となり、口部８を封鎖した開封用シート部９を開封具１２で不用意に破断する事故は決して発生しない。のみならず、飲用に際して開封紐１５を取り除いた後は、２箇所のネジ７と１７の働きで開封具１２を強力に前進させられるから、開封用シート部９の破断を一層強力に確実に行うことができる。
図８の場合は、容器本体２の胴部下端の外周に、付属容器４の繋ぎ胴部１３の肉厚相当分だけ小径とした段差部２０を形成し、付属容器４を容器本体へ付属させた際には、繋ぎ胴部１３の上端部を容器本体２の前記段差部２０の外周面へ嵌め込み、その上で付属容器４の繋ぎ胴部１３と容器本体２の胴部下端とを細幅の開封紐１５を介して一体的に接合した構成である。したがって、容器本体２と付属容器４との一体性は安定な嵌め込み状態となり、口部８を封鎖した開封用シート部９を開封具１２で不用意に破断する事故を未然に防止できる。
【００２０】
次に、図９は、本発明の飲料容器を、乳児用の哺乳瓶として実施した形態を示している。
飲料容器としての構造は、上記の実施形態とほとんど変わりがない。容器本体２に収納された液体１が適温のお湯であり、付属容器４の容室１１に収納された原料等３は粉ミルク又は濃縮液体ミルクである。本実施例の特徴は、キャップ５に乳首２１を一体的に設け、同乳首２１は衛生的な保護キャップ２２で安全な殺菌状態を保持して保護した構成の点にある。
上記構成の飲料容器は、例えば温度管理ができる自動販売機、ショーケースなどに収納して、液体１を乳児が飲むミルクに適切な温度のお湯に保って販売するものである。したがって、乳児の母などは、哺乳瓶や粉ミルクの用意をすることなく外出し、或いは旅行等を行うことができる。授乳時期になると、当該飲料容器を購入し、上述した要領で付属容器４内の粉ミルク又は濃縮液体ミルクをお湯と混合してミルクとなし乳児に飲ませることができる。衛生管理の面で言えば、容器本体２の液体１（お湯）の収容量を、一回の授乳量とほぼ同量にすると使い捨てができて至便である。
【００２１】
次に、図１０と図１１は、付属容器４０に収納させる原料等３’が粒状、顆粒状、又はブロック状などの固形物である場合の実施形態を示す。
この実施形態の飲料容器も、大部分の構成は上記第１の実施形態とほぼ同じである。本実施形態の特徴は、付属容器４０に収納させる原料等３’が固体であることを前提として、付属容器４０の口部４１の外径が容器本体２の胴部外径と略同じ外径の広口キャップ状に形成され、その内側が全部容室４２に形成されていることである。固体状の原料等３’は、粉体の場合とは異なって安息角の概念が無用であり、開封用シート部９を開封した際の落下移動が容易でスムーズに行われるからである。容器本体２の下底部には、前記付属容器４０の口部４１の内周面に形成したネジが結合されるネジ１７を外周面に形成した広口の口部８’が形成され、その開口が開封用シート部９により全面封鎖されている。
【００２２】
付属容器４０の底壁中央部に前記容器本体２の開封用シート部９を突き破るための開封具１２が立ち上げられている。また、容器本体２の下底部の口部８’へネジ結合した付属容器４０の口部４１の上端と容器本体２の胴部下端とが細幅の開封紐１５で接合されていることは、上記の各実施形態と同じである。また、付属容器４０の容室４２へ収納させた固体状の原料等３’は、不活性ガス１６を注入・充填して不活性ガス雰囲気に保持することも同様である。容器本体２の開封用シート部９には、上記開封具１２による開封を促進する破断誘導処理が行われる。
【００２３】
この飲料容器の中身を飲用するには、やはり図１１のように当該容器を逆さ状態に倒立させて持つ。そして、上記実施形態と同様に開封紐１５を引き剥がし、隙間Ｓを形成する。次に付属容器４０を回して強くねじ込むと、開封具１２が前進して開封用シート部９を突き破る。すると固体状の原料等３’が下方の液体１中へ落下して混合される。後は当該容器をよく振って混合を完全に行い飲料となす。しかる後に、容器を元の正常な立ち姿に戻し、キャップ５をあけて中身を飲用に供することになる。
もっとも、本実施形態の場合は、飲料容器を図１１のように倒立させた状態のまま、付属容器４０のネジ結合を解くようにして完全に外し（開けて）、開封用シート部９の残骸を除去することにより、そのまま中身を飲用する使用法も可能である。こうした用途を前提とすると、頭部にキャップ５及び口部６を持たない飲料容器として実施することも可能である。この点は、上記図１〜図８の実施例についても同様に云えることである（請求項１に記載した発明）。
【００２４】
【本発明が奏する効果】
以上に説明したように、請求項１〜４に記載した発明に係る飲料容器は、容器の構造が至極簡単で、容器本体と付属容器はそれぞれ例えばブロー成型法等によりワンショットで簡単に成形することができる。また、原料等を収納させ、且つ不活性ガスを注入・充填した付属容器を容器本体へ付属させることもワンタッチ的に簡単に行え、要するに製造が容易で安価に提供できる。
次に、本発明に係る飲料容器の材質は、所謂ペットボトル（ポリエチレンテレフタレートボトル）等のプラスチック系素材で、又は鉄系或いはアルミニウム系の缶として、或いは紙容器、ガラス容器等の別を問わず実施できる。しかも長期間飲料中身の品質、鮮度、風味などを保証して安価に提供することができる。
勿論、本発明に係る飲料容器の中身は、お茶、コーヒー、乳製品、果汁等のジュース類、ビタミン等の機能性飲料、アルコール類等の別を問わず実施できる。それらの原料等が液体又は粉体であるか固形、顆粒状であるかの形体の別を問わず容易に実施可能でもある。

DETAILED DESCRIPTION OF THE INVENTION
Below, embodiment of the drink container which attached | separated and attached the raw material etc. based on the invention described in Claims 1-4 is described based on drawing.
First, FIGS. 1-6 shows embodiment in case raw materials etc. are powders, such as powdered milk and powdered coffee. This beverage container is composed of a combination of a container body 2 for storing a liquid 1 such as drinking water and an accessory container 4 for storing a raw material 3 for mixing with the liquid 1 to make a target beverage. 1 to 6 also show that the container body 2 and the accessory container 4 are plastic-type bottle-shaped containers known as so-called PET bottles, but are not limited thereto.
The container body 2 has a cap 5 at its upper end that can be attached and detached in the same manner as a regular PET bottle, and has a mouth 6 for drinking a beverage, but also has a mouth 7 having a screw 7 on its outer peripheral surface. Part 8. And the opening part 9 of the thin part as a whole which sealed the opening of the said mouth part 8 watertightly is formed by the structure which can be fractured | ruptured and opened if necessary. As shown in FIG. 3, the opening sheet portion 9 has a cruciform induction process 9a, such as a cut groove that is easy to break, to facilitate opening by an opening tool, which will be described later, in a cross shape as shown in FIG. Or a spiral shape or the like (the invention according to claim 3).
[0015]
On the other hand, the attached container 4 is configured to form a part of the bottom of the container body 2 as a whole. The accessory container 4 is formed with a mouth portion 10 having a screw coupled to the screw 7 of the mouth portion 8 at the lower bottom portion of the container body 2 on the inner peripheral surface. A chamber 11 is formed for storing the raw material 3 for mixing with the liquid 1 to make a target beverage. And the opening tool 12 which penetrates the sheet | seat part 9 for opening which sealed the opening of the said opening part 8 of the container main body 2 is provided in the shape of the protrusion which stands | starts up from the bottom wall of the container chamber 11. FIG. The unsealing tool 12 has a height that never hits the unsealing sheet portion 9 that seals the opening of the mouth portion 8 of the container body 2 when not drinking. On the other hand, when the mouth part 10 of the accessory container 4 is screwed in strongly during drinking, the opening device 12 breaks the opening sheet part 9 into a state necessary and sufficient for the powdery raw material 3 to pass (spill out). It is formed in the height and shape that can be made. When the upper surface wall 11a forming the container chamber 11 of the attached container 4 is turned upside down as shown in FIG. 5, the opening sheet portion 9 that seals the opening of the mouth portion 8 of the container body 2 is broken. The powdery raw material 3 is formed on an inclined surface having an angle of repose or more of the same powder so that the powdery raw material 3 spills smoothly from the breakage point to the lower liquid 1 without staying smoothly. However, when the raw material 3 is liquid, granular, granular or the like, the inclination angle of the upper surface wall 11a is not necessarily required.
[0016]
The attached container 4 having the above configuration is attached to the lower part of the container body 2 by screwing the mouth part 10 with the mouth part 8 on the lower bottom part of the container body 2. However, a predetermined raw material 3 or the like is previously placed in the container 11 of the attached container 4 and stored. Furthermore, the inert gas 16 (nitrogen gas, helium gas, argon gas, carbon dioxide, nitrous oxide, etc.) that keeps the quality, freshness, flavor, etc. of the raw material 3 safe for a long time and has little pressure change due to temperature difference. Is injected and filled to maintain the inert atmosphere (the invention according to claim 3).
Alternatively, a method in which the powdery raw material 3 or the like 3 is mixed into the chamber 11 together with the inert gas 16 to which a little pressure is applied, and is filled in a high pressure state can also be implemented. Since the inert gas 16 has a larger mass and less spontaneous release than air, the state of being injected into the chamber 11 is naturally maintained as it is. Therefore, the mouth portion 10 of the attached container 4 can be screwed with the mouth portion 8 on the lower bottom portion of the container body 2 as it is, and can be attached to the lower portion of the container body 2, so that simple handling and processing can be performed. Since it is as above-mentioned, the capacity | capacitance of the chamber 11 is formed in the magnitude | size of the accommodation quantity which can be made into a drink by mixing the quantity of the liquid 1 accommodated in the container main body 2, and the raw material 3 etc.

And when the attached container 4 which accommodated the raw materials 3 etc. was attached to the lower bottom part of the container main body 2 as mentioned above, the connecting trunk | drum 13 which forms a trunk | drum of a container main body 2 and a series of trunk | drums further. They are integrally joined to each other through an opening string 15 having a width of about 2 mm to 5 mm (the invention according to claim 2). Therefore, the attached container 4 cannot be rotated with respect to the container body 2 unless the opening string 15 is released and removed, and therefore the opening sheet portion that seals the mouth 8 at the lower bottom of the container body 2. The accident that breaks 9 with the opening tool 12 carelessly never occurs. When the beverage container is viewed from the outside, the presence of the opening string 15 is visually recognized, but the accessory container 4 is integrated with the container body 2 so that its presence is not visually recognized. Presents the design of the vessel. Therefore, the beverage container of the present invention satisfies the conditions such as the standardized shape and dimensions of existing containers such as PET bottles that are already on the market when the container body 2 and the accessory container 4 are combined as described above. It can be set as a structure, and it can be set as the structure which can be sold in common with the existing vending machine and a showcase (invention described in Claim 2).
[0018]
Since the beverage container of the present invention is configured and used as described above, when drinking a content beverage, the beverage container is first inverted and held in an inverted direction as shown in FIG. First, the opening string 15 is peeled off and removed. Then, at least a gap S corresponding to the width of the opening string 15 is generated between the lower end of the body portion of the container body 2 and the connecting body portion 13 of the accessory container 4, so that the accessory container 4 can rotate. Therefore, the accessory container 4 is rotated with respect to the container body 2, and the screw connection of the mouth portion 10 of the accessory container 4 joined to the screw 7 of the mouth portion 8 at the lower bottom portion of the container body 2 is pushed forward as shown in FIG. 5. Then, the opening tool 12 of the attached container 4 moves forward, and the opening sheet portion 9 that seals the mouth portion 8 of the lower bottom portion of the container body 2 is pierced and opened as shown in the conceptual diagram of FIG. Accordingly, the powdery raw material 3 stored in the chamber 11 of the accessory container 4 spills quickly and smoothly from the broken gap toward the container body 2, and the liquid 1 stored in the container body 2 is removed. It falls and mixes in. Therefore, the beverage container is shaken well as it is, and the raw material 3 and the liquid 1 are sufficiently mixed to make a beverage. After that, the beverage container is returned to its original normal standing state as shown in FIGS. 1 and 2, and the cap 5 is opened to use the contents for drinking.
The raw materials 3 are stored and stored in an inert gas atmosphere in an attached container 4 separated and independent from the liquid 1 until just before drinking, and oxidation, deterioration, decay, discoloration, etc. due to ultraviolet rays are prevented. Therefore, its quality, flavor, taste, freshness, etc. are maintained over a long period of time, and a fresh and delicious beverage can be provided at any time. Even when the liquid 1 is drinking water, a shelf life of 2 to 3 years can be guaranteed.
[0019]
