Description

【０００１】
【発明の属する技術分野】
本発明は飲料容器、例えばペットボトルの改良に係り、より詳しくは飲料水からなる液体成分を本体に、また粉末茶からなる粉末成分をキャップの収納部に別個に収納しておき、これら両者を飲用時に混合して飲用するようにしたペットボトルに関するものである。
【０００２】
【従来技術】
ペットボトル１００の本体１０１に飲料水１０２を充填し、その本体１０１の瓶口１０３をキャップ１０４をネジ着して密閉し、さらにキャップ１０４の内面に突出形成した常時は瓶口内に位置する筒形の収納部１０５に粉末茶（顆粒状の食味材）１０６を入れ、その開口端１０７をシール材１０８でシールした液体成分と粉末成分とを別個に収納させたペットボトルが提案されている。（例えば、特許文献１参照）。
【０００３】
【特許文献１】
特開２００２−１１４２５９号公報（第１頁、図３）。
【０００４】
【発明が解決しようとする課題】
上記従来のものは、飲用時、キャップ１０４を一旦取外して収納部１０５のシール１０８を剥がし、収納部内の粉末茶（食味材）１０６を本体１０１の飲料水１０２中に投入し、再度キャップ１０４をネジ着して混合後、瓶口より取外して飲用するようにしている。
つまり飲用時に初めて粉末茶を飲料水と混合し飲用するため、飲用時には粉末茶本来の風味を損なわない美味しいお茶が味わえる特長がある。
つまり、予め茶葉のエッセンスを飲料水に溶かして作ったり或いは茶葉をお湯で抽出して作ったりしたもの等のように品質を維持するための酸化防止剤や保存剤を添加する必要がなく、お茶自体の味が味わえる。
【０００５】
ところで、上記従来型のペットボトルは、収納部内の粉末茶（食味材）を飲料水と混合するに際し、一旦キャップを取外す必要があること、また、収納部内の粉末茶をペットボトルの瓶口より入れなければならず特に風のある屋外などではこぼしたりし易いこと、収納部が筒形のため奥の粉末茶が全部出ず残留しやすいこと、アルミ箔等の貼着によるシール構造のため浸漬状態にある時は剥がれ易く気密信頼性に欠けること等の問題があった。
【０００６】
【問題を解決するための手段】
本願発明は上記問題点を解決するもので、
第１の発明は、飲料水３を充填した本体２の瓶口２ａのネジ部２ｄに取脱自在にキャップ４をネジ着し、該ネジ着したキャップ４には粉末茶８を密閉収納してなる中筒体７をキャップのネジ着時に瓶口内に挿入される状態で同キャップに脱着可能に連結すると共にさらにキャップ取外時に該中筒体７を飲料水中に落下せしめて中筒体７の収納部７ａ内の粉末茶８と飲料水３とを混合させるようにしたペットボトルにおいて、
上記、中筒体７は粉末茶８を収納するための収納部７ａと同収納部の底部７ｄに設けたガイド穴７ｅと、キャップのネジ着時、本体２の瓶口２ａの下端係止部２ｆに係止する係止部７ｃとからなり、また、キャップは収納部の上面の開口端７ｉに嵌合密着して同開口端を閉鎖する閉鎖部４ｅと、収納部７ａのガイド穴７ｅを気密的に通過するガイド穴径と同径乃至は若干大きめの外径からなる密栓部６ｂを設けた支持棒６とからなることを特徴とするペットボトルを提案するものである。
【０００７】
また、第２の発明は、飲料水３を充填した本体２の瓶口２ａのネジ部２ｄに取脱自在にキャップ４をネジ着し、該ネジ着したキャップ４には粉末茶８を密閉収納してなる中筒体７をキャップのネジ着時に瓶口内に挿入される状態で同キャップに脱着可能に連結すると共にさらにキャップ取外時に該中筒体７を飲料水中に落下せしめて中筒体７の収納部７ａ内の粉末茶８と飲料水３とを混合させるようにしたペットボトルにおいて、
上記、中筒体７は粉末茶８を収納するための収納部７ａと同収納部の底部７ｄに設けたガイド穴７ｅと、キャップのネジ着時、本体２の瓶口２ａの下端係止部２ｆに係止する係止部７ｃとからなり、また、キャップ４は収納部７ａの上面の開口端７ｉに嵌合密着して同開口端７ｉを閉鎖する閉鎖部４ｅと、収納部７ａのガイド穴７ｅを気密的に通過するガイド穴径と同径乃至は若干大きめの外径からなる密栓部６ｂと、下端側を押圧寸法が確保される長さでガイド穴より下方に突出させると共にさらに突出した下端部６ｃにはガイド穴の穴径より大きな外径からなる押圧部６ｆを形成したキャップにネジ着する支持棒６とからなることを特徴とするペットボトルを提案するものである。
【０００８】
また、第３の発明は、上記支持棒６の下端の押圧部６ｆを下方に拡開形成するテーパ状に形成すると共にさらに該押圧部６ｆには支持棒６のガイド穴７ｅからの離脱方向に沿ってガイド穴７ｅからの離脱時その外径寸法を小さくするためのスリ割６ｇを設けたことを特徴とする請求項２に記載のペットボトルを提案するものである。
【０００９】
また、第４の発明は、飲料水３を充填した本体２の瓶口２ａのネジ部２ｄに取脱自在にキャップ４をネジ着し、該ネジ着したキャップ４には粉末茶８を密閉収納してなる中筒体７をキャップのネジ着時に瓶口内に挿入される状態で同キャップに脱着可能に連結すると共にさらに飲料の際のキャップ取外時に該中筒体７を飲料水３中に落下せしめて中筒体７の収納部７ａ内の粉末茶と飲料水とを混合させるようにしたペットボトルにおいて、
上記、中筒体７は粉末茶８を収納するための収納部７ａと同収納部７ａの底部７ｄに設けたガイド穴７ｅと、キャップのネジ着時、本体２の瓶口２ａの下端係止部２ｆに係止する係止部７ｃとからなり、また、キャップ４は収納部７ａの上面の開口端７ｉに嵌合密着して同開口端を閉鎖する閉鎖部４ｅと、下端側を押圧寸法が確保される長さでガイド穴より下方に突出させると共にさらに突出した下端部６ｃにはガイド穴の穴径より大きな外径からなる押圧部６ｆを形成したキャップと一体の支持棒６とからなることを特徴とするペットボトルを提案するものである。
【００１０】
【発明の実施の形態】
以下、本願発明の実施形態を図面に基づき説明する。
図１乃至は図６は本願発明の第１の実施例を示す。
１はペットボトルであり、ペット樹脂（ＰＥＴ）などの合成樹脂製の本体２内にはミネラルウォーター等の飲料水３が充填されている。
また、４は本体２の上部の瓶口２ａに取脱自在にネジ着されるポリプロピレン樹脂（ＰＰ）などの合成樹脂製のキャップであり、側周部４ａの内周壁面４ｂに形成したネジ部４ｃを瓶口２ａの外周面２ｃに形成したネジ部２ｄに対し取脱自在にネジ着している。
【００１１】
またキャップ４の内面には環状の溝部４ｄが形成され、該溝部４ｄにはキャップのネジ着時、瓶口の開口端２ｅに当接するパッキン５が設けられている。
また内面中央には下方に突出する閉鎖部４ｅが形成され、上下２段に形成した外周面４ｆの下部側の小径の外周面には凹状の脱着部４ｇが形成され、さらに閉鎖部４ｇの下端４ｈの長さが側周部４ａの下端４ｉに比して短く形成されている。
【００１２】
また、さらに閉鎖部４ｅには中央に位置してネジ部４ｊが形成され、該ネジ部には後述の支持棒６がネジ着される。
この閉鎖部４ｅのネジ部４ｊと支持棒６のネジ部６ａのネジ関係は、キャップと瓶口のネジ部のネジ着関係とは逆の関係になっている。
つまり、キャップと瓶口の関係が普通ネジ（右ネジ）の関係になっているのに対し、キャップの閉鎖部４ｅのネジ部４ｊと支持棒６のネジ部６ａとのネジ着は左ネジになっており、逆ネジ関係になっている。
【００１３】
７はポリプロピレン樹脂（ＰＰ）、ペット樹脂（ＰＥＴ）等の合成樹脂製の中筒体であり、キャップの閉鎖部４ｅに対し連結される。
中筒体７は収納部７ａと係止部７ｃとからなり、
収納部７ａには上部側の開口端に位置して凸状の被脱着部７ｋと、底部７ｄと、その底部７ｄの中央に位置するガイド穴７ｅとが形成されており、
さらに係止部７ｃには本体２の瓶口２ａの下端係止部２ｆに係止する係止爪部７ｆと、その係止爪部等に適当な弾力を付与するためのスリ割７ｇが形成されている。
【００１４】
６は上記の如くポリプロピレン樹脂（ＰＰ）等の合成樹脂製の支持棒であり、支持棒６の上端のネジ部６ａをキャップ４のネジ部４ｊにネジ着したもので、前述したようにキャップと支持棒とのネジ着は逆ネジの関係でネジ着される。
【００１５】
なお、支持棒６はその下端側付近の密栓部６ｂを収納部７ａの底部７ｄのガイド穴７ｅに挿入して通過させると共にさらに下端部６ｃを同ガイド穴７ｅより若干突出させるようにしている。
また、さらに上記支持棒６はガイド穴７ｅが通過している部分つまり密栓部６ｂの外径がガイド穴７ｅの穴径と同径乃至はそれより若干大きく形成されており、密栓部６ｂがガイド穴７ｅに密着して収納部７ａの気密性を維持するようにしているほか、必要によりガイド穴７ｅより突出する下端部６ｃの端面６ｄに＋、−のドライバー用の嵌合溝や六角レンチ用の六角段穴等の工具用嵌合穴６ｅを形成し、同棒６とキャップ４とのネジ着時におけるネジ着操作をし易くしている。
【００１６】
次ぎに図１及び図３によりキャップと中筒体の組立及びこれら組立てたものを瓶口へ装着する場合に付き説明する。
【００１７】
図２に示すように、まず、中筒体７に対し支持棒６を組付ける。支持棒６を収納部７ａの底部７ｄの下面側から同棒の密栓部６ｂが丁度ガイド穴７ｅに位置するまで挿入する。この状態で収納部７ａの開口端７ｉ側からお茶スリ器等により微粉砕した粉末茶８を収納部７ａ内に充填する。
【００１８】
充填後、キャップ４のネジ部４ｊと支持棒６の上端のネジ部６ａとをネジ着し、最後まで締め付ける。最後まで締め付けるとキャップの閉鎖部４ｅが収納部７ａの開口端７ｉに密着嵌合し同開口端を閉鎖する。
またこの場合、キャップ４の閉鎖部４ｅの脱着部４ｇが収納部７ａの開口端７ｉの被脱着部７ｋに嵌って中筒体７とキャップ４は適当な嵌合力により連結された状態となる。これにより、収納部７ａに充填された粉末茶８はキャップの閉鎖部４ｅと支持棒の密栓部６ｂとにより密封された状態になる（図３参照）。
【００１９】
なお、キャップ４と支持棒６とは上記したように逆ネジの関係にあるため、支持棒６を左回してネジ着するが、この場合、下端側の工具用嵌合穴６ｅにドライバーを差し込み同棒を操作すれば一段とネジ着操作がし易くなる。
【００２０】
上記、収納部に粉末茶８を収納した中筒体７とキャップ４とを支持棒６により連結したものを次ぎに瓶口２ａに装着する。
瓶口２ａに装着する場合、スリ割７ｇを利用して係止爪部７ｆ側を若干窄めた状態で係止爪部７ｆ側から瓶口２ａに挿入する。
【００２１】
そしてキャップを少し強く押さえるようにしながらキャップのネジ部４ｃを瓶口２ａのネジ部２ｄにネジ合わせし締め込んで行く。締め込みによりキャップと一体の中筒体７も下方に押し込まれやがて係止爪部７ｆが瓶口２ａの下端係止部２ｆを乗り越えと、今まで瓶口の内周壁面により外方への広がりが拘束されていた係止爪部７ｆが自体の弾力により外側に広がり、瓶口の下端係止部２ｆに係止し、中筒体７は瓶口２ａからの離脱（上方への離脱）が阻止される。
なお、この場合、キャップは最終的に締付けが完了した状態にあり、キャップ内面のパッキン５は瓶口２ａの開口端２ｅに当接してペットボトル１の気密が維持される（図１参照）。
【００２２】
次ぎに飲用時に付いて図１、図４、図５、図６に基づき説明する。
飲用に際し、図１の状態において、ペットボトル１のキャップ４を左に少し回してネジを緩めと、キャップ４の側周部４ａの下端の不正開放確認部４ｌがキャップの回転に伴って離脱し、一度キャップを開放したことを知らしめる。同時にキャップ４と一体の中筒体７も上方へ移動しようとする。しかし、この時、中筒体７の係止爪部７ｆが瓶口の下端係止部２ｆに係止し、中筒体７は瓶口よりの離脱つまり上方への移動が阻止され、キャップ４の閉鎖部４ｅが収納部７の開口端７ｉより離脱する（図４参照）。
【００２３】
また、この時、キャップと一体の支持棒６も上方（引抜き方向）に移動し、さらにキャップを同方向に回すことにより密栓部６ｂ、次いで下端部６ｃが収納部７ａのガイド穴７ｅから離脱する（図５参照）。
このガイド穴からの離脱は視認できるほか回す力（操作力）が急に軽くなることで自覚できる。
この離脱により中筒体７は拘束されるものが無くなり、自重及び離脱時の反動により本体２内の飲料水３中に落下する（図６参照）。
【００２４】
中筒体７が飲料水に落下した後、キャップを再度締め直し、ボトルを振って混合する。この場合、飲料水中にある中筒体が攪拌部材の役目をし、攪拌が促進され、素早く混合される。混合後、再度、キャップを緩め瓶口より取外し、飲用する。
【００２５】
次ぎに第２の実施例について説明する。
図７乃至図９は第２の実施例を示すもので、
前記、第１の実施例とは、粉末茶を収納する中筒体を支持棒により強制的に飲料水中に落下せしめる点が相違する。
そのため、支持棒６の下端側つまりガイド穴７ｅからの突出寸法ａを長く延長すると共にさらに支持棒の下端にはガイド穴径より外径寸法を大きくした押圧部６ｆを設けている。
【００２６】
つまり、図において、キャップ４を回して緩め、一旦支持棒６をガイド穴７ｅから離脱させた後、再びキャップ４を締付ける方向に回す時、支持棒６の下端側の押圧部６ｆが、収納部７ａの底部７ｄの上面７ｂ側を下方へ押圧して中筒体７を強制的に飲料水中に落下せしめるようしたもので、ガイド穴７ｅから突出する支持棒６のその下端側の長さを延長形成することにより、上記中筒体７に対する押圧落下が適確に行える寸法を確保するようにしている。
【００２７】
なお本実施例では、支持棒６は下端側の長さａを延長形成するだけでなく、さらにその下端に押圧部６ｆを形成した点でも相違している。該押圧部６ｆはガイド穴７ｅの穴径より外径寸法を大きくした下方に拡開するテーパー形状であり、押圧部６ｆのガイド穴７ｅからの離脱をし易くすると共に一旦離脱した後は該押圧部６ｆのガイド穴７ｅへの再挿入が阻止され、確実に底部７ｄの上面７ｂ側を押圧するようになっている。
上記目的を達成するため押圧部６ｆには、抜き差し方向に形成した弾性を付与するためのスリ割６ｇを必要により設けるようにしても良い。
【００２８】
次ぎに第３の実施例に付いて説明する。
図１０乃至図１１は第３の実施例を示すもので、
前記、第１の実施例とは、キャップ４と支持棒６とが連結可能なネジ着構造ではなく、両者が一体形成されている点で相違する。
つまり、粉末茶８を中筒体７に充填する場合、収納部７ａの底部７ｄのガイド穴７ｅから粉末茶８がこぼれ落ちないように、ガイド穴７ｅに支持棒６の下端部６ｃを挿入すると共にキャップ４を持ち上げながら、キャップの閉鎖部４ｅと中筒体の収納部７ａの開口端７ｉ間で形成する隙間から収納部内へ粉末茶８を入れるようにしている。
【００２９】
次ぎに第４の実施例に付いて説明する。
図１２は第４の実施例を示すもので、
前記、第２の実施例の場合キャップと瓶口のネジ部のネジ着が外ネジ方式であるのに対し、本実施例ではキャップ４と中筒体７のネジ着構造が内ネジ方式である点で相違する。つまり、キャップは閉鎖部４ｅの外周面４ｆにネジ部４ｃが形成され、瓶口２は瓶口２ａの内周壁のにネジ部２ｄが形成されている。
【００３０】
なお、上記各実施例はいずれも粉末成分として粉末茶を使用した場合に付いて説明したが、これに限定されることなく、コーヒー粉末、ジュース粉末やその他の食味材粉末の場合のペットボトルとして使用する場合にも実施可能である。
【００３１】
【発明の効果】
請求項１及び２においては、
従来例の如く、粉末茶を飲料水に混合するために一旦キャップを取外すような面倒な操作も必要でなく、一度のキャップの取外し操作により、中筒体が水中に落下するため、中筒体の収納部内の粉末茶が同部内に残ることなく無駄なく飲料水と混合できる。
【００３２】
また、飲料水中に中筒体が落下した状態でペットボトルを振れば、中筒体が攪拌部材の働きをし、粉末茶は素早く確実に飲料水と混合できる。
また、キャップと支持棒がネジ着構造のため、収納部に粉末茶を入れる場合にキャップを外して収納部の開口端が開放した状態で粉末茶を入れることが出来るため、粉末茶の充填作業がし易い。
【００３３】
また、収納部に充填された粉末茶は、通常時においては、その上端側の開口端がキャップの閉鎖部により、また底部側のガイド穴が支持棒により気密的に閉鎖されるため収納部の気密が長期維持され、粉末茶を変質させたりしない。
また、飲料水中に落下した中筒体の収納部は開口端、ガイド穴が共に開放された状態で混合されることになるため、飲料水の流通が良くなり、収納部内に粉末茶を残したりしない。
【００３４】
さらに、請求項２及び４においては、
常時は収納部内の粉末茶を気密的に維持できると共に飲料の際のキャップの取外時、支持棒により中筒体を飲料水中に落下せしめることが出来るため、確実な混合が行える。
【００３５】
また、請求項３においては、
支持棒は、ガイド穴に対する離脱がし易く逆に離脱後はガイド穴の底部を的確押圧することが可能になり、確実に中筒体を飲料水中に落下させることができる。

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 6 show a first embodiment of the present invention.
Reference numeral 1 denotes a PET bottle. A main body 2 made of a synthetic resin such as a PET resin (PET) is filled with drinking water 3 such as mineral water.
Reference numeral 4 denotes a cap made of a synthetic resin such as polypropylene resin (PP), which is detachably screwed to the bottle opening 2a on the upper part of the main body 2, and a screw portion formed on the inner peripheral wall surface 4b of the side peripheral portion 4a. 4c is detachably screwed to a screw portion 2d formed on the outer peripheral surface 2c of the bottle mouth 2a.
[0011]
An annular groove 4d is formed on the inner surface of the cap 4, and a packing 5 is provided in the groove 4d so as to abut the opening end 2e of the bottle mouth when the cap is screwed.
A closed portion 4e projecting downward is formed at the center of the inner surface, and a concave detachable portion 4g is formed on a small-diameter outer surface on the lower side of the outer surface 4f formed in two steps in the upper and lower stages, and a lower end of the closed portion 4g is further formed. The length 4h is shorter than the lower end 4i of the side peripheral portion 4a.
[0012]
Further, a screw portion 4j is formed at the center of the closing portion 4e, and a support rod 6 described later is screwed to the screw portion.
The screw relationship between the screw portion 4j of the closing portion 4e and the screw portion 6a of the support rod 6 is opposite to the screw connection relationship between the cap and the screw portion of the bottle opening.
In other words, while the relationship between the cap and the bottle mouth is a normal screw (right-handed screw), the screw connection between the screw portion 4j of the cap closing portion 4e and the screw portion 6a of the support rod 6 is formed by a left-handed screw. It has a reverse screw relationship.
[0013]
Reference numeral 7 denotes a middle cylinder made of a synthetic resin such as a polypropylene resin (PP) or a pet resin (PET), and is connected to the closing portion 4e of the cap.
The middle cylinder 7 includes a storage portion 7a and a locking portion 7c,
The storage portion 7a is formed with a detachable portion 7k having a convex shape located at the opening end on the upper side, a bottom portion 7d, and a guide hole 7e located at the center of the bottom portion 7d.
Further, the locking portion 7c is formed with a locking claw portion 7f for locking to the lower locking portion 2f of the bottle opening 2a of the main body 2, and a slot 7g for imparting an appropriate elasticity to the locking claw portion and the like. Have been.
[0014]
Reference numeral 6 denotes a support rod made of a synthetic resin such as polypropylene resin (PP) as described above. The support rod 6 is formed by screwing a screw portion 6a at the upper end of the support rod 6 to a screw portion 4j of the cap 4. The connection with the support rod is screwed in a reverse screw relationship.
[0015]
The support rod 6 is configured such that the plug 6b near the lower end thereof is inserted into and passed through the guide hole 7e of the bottom 7d of the storage portion 7a, and the lower end 6c is slightly projected from the guide hole 7e.
Further, the support rod 6 has a portion through which the guide hole 7e passes, that is, the outer diameter of the sealing portion 6b is formed to be equal to or slightly larger than the hole diameter of the guide hole 7e. In addition to maintaining the airtightness of the storage portion 7a in close contact with the hole 7e, the end face 6d of the lower end portion 6c protruding from the guide hole 7e is provided with a fitting groove for a + or-driver or a hexagon wrench as necessary. The hole 6e for a tool such as a hexagonal step hole is formed to facilitate the screwing operation when the rod 6 and the cap 4 are screwed.
[0016]
Next, referring to FIGS. 1 and 3, the assembly of the cap and the intermediate cylinder and the case where these assembled parts are mounted on the bottle mouth will be described.
[0017]
As shown in FIG. 2, first, the support rod 6 is attached to the middle cylinder 7. The support rod 6 is inserted from the lower surface side of the bottom part 7d of the storage part 7a until the sealing part 6b of the same rod is just located in the guide hole 7e. In this state, the powdered tea 8 finely pulverized with a tea sanding machine or the like is filled into the storage portion 7a from the opening end 7i side of the storage portion 7a.
[0018]
After the filling, the screw portion 4j of the cap 4 and the screw portion 6a at the upper end of the support rod 6 are screwed and tightened to the end. When the cap is tightened to the end, the closing part 4e of the cap fits tightly with the opening end 7i of the storage part 7a and closes the opening end.
In this case, the detachable portion 4g of the closing portion 4e of the cap 4 is fitted to the detached portion 7k of the opening end 7i of the storage portion 7a, and the middle cylinder 7 and the cap 4 are connected by an appropriate fitting force. Thus, the powdered tea 8 filled in the storage portion 7a is sealed by the closing portion 4e of the cap and the sealing portion 6b of the support rod (see FIG. 3).
[0019]
Since the cap 4 and the support bar 6 have a reverse screw relationship as described above, the support bar 6 is screwed by turning the counterclockwise counterclockwise. In this case, a driver is inserted into the tool fitting hole 6e on the lower end side. By operating this rod, the screwing operation becomes easier.
[0020]
The above-mentioned storage unit, in which the powdered tea 8 is stored and the cap 4 connected with the cap 4 by the support rod 6, is then attached to the bottle opening 2a.
When attaching to the bottle mouth 2a, the locking claw 7f side is inserted into the bottle mouth 2a from the locking claw 7f side in a state where the locking claw 7f side is slightly narrowed using the slot 7g.
[0021]
Then, the screw 4c of the cap is screwed into the screw 2d of the bottle opening 2a while the cap is slightly pressed down, and tightened. The middle cylinder body 7 integrated with the cap is also pushed downward by the tightening, and the locking claw 7f eventually rides over the lower locking part 2f of the bottle mouth 2a, and spreads outward by the inner peripheral wall surface of the bottle mouth until now. The locking claw portion 7f, which has been restrained, spreads outward due to its own elasticity and locks to the lower end locking portion 2f of the bottle mouth, so that the middle cylinder 7 is detached from the bottle mouth 2a (upward detachment). Will be blocked.
Note that, in this case, the cap is in a state where the tightening is finally completed, and the packing 5 on the inner surface of the cap comes into contact with the opening end 2e of the bottle mouth 2a to maintain the airtightness of the PET bottle 1 (see FIG. 1).
[0022]
Next, the case of drinking will be described with reference to FIGS. 1, 4, 5, and 6. FIG.
At the time of drinking, in the state of FIG. 1, the cap 4 of the plastic bottle 1 is slightly turned to the left to loosen the screw, and the unauthorized opening confirmation part 41 at the lower end of the side peripheral part 4a of the cap 4 is detached with the rotation of the cap. Let me know that you've opened the cap once. At the same time, the middle cylinder 7 integral with the cap 4 also attempts to move upward. However, at this time, the locking claw portion 7f of the middle cylinder 7 is locked to the lower engagement portion 2f of the bottle mouth, so that the middle cylinder 7 is prevented from detaching from the bottle mouth, that is, moving upward. Is separated from the opening end 7i of the storage section 7 (see FIG. 4).
[0023]
At this time, the support rod 6 integrated with the cap also moves upward (pull-out direction), and further turns the cap in the same direction, whereby the hermetic plug portion 6b and then the lower end portion 6c are separated from the guide hole 7e of the storage portion 7a. (See FIG. 5).
The detachment from the guide hole can be visually recognized, and the turning force (operating force) suddenly becomes lighter, so that the driver can recognize the detachment.
Due to this detachment, the middle cylinder 7 is released from being restrained, and falls into the drinking water 3 in the main body 2 due to its own weight and a reaction at the time of detachment (see FIG. 6).
[0024]
After the middle cylinder 7 falls into the drinking water, the cap is retightened and the bottle is shaken to mix. In this case, the middle cylinder in the drinking water functions as a stirring member, stirring is promoted, and mixing is performed quickly. After mixing, loosen the cap again, remove from the bottle mouth, and drink.
[0025]
Next, a second embodiment will be described.
7 to 9 show a second embodiment.
The second embodiment is different from the first embodiment in that a middle cylinder for storing powdered tea is forcibly dropped into drinking water by a support rod.
For this reason, a protruding dimension a from the lower end side of the support rod 6, that is, the guide hole 7e, is extended and a pressing portion 6f having an outer diameter larger than the guide hole diameter is provided at the lower end of the support rod.
[0026]
That is, in the figure, when the cap 4 is turned to loosen, the support rod 6 is once separated from the guide hole 7e, and then the cap 4 is turned again in the tightening direction, the pressing portion 6f on the lower end side of the support rod 6 The upper surface 7b side of the bottom 7d of the bottom 7a is pressed downward to forcibly drop the middle cylinder 7 into drinking water, and the length of the lower end side of the support rod 6 protruding from the guide hole 7e is extended. By forming, the dimension which can press and fall to the above-mentioned middle cylinder 7 correctly can be secured.
[0027]
In this embodiment, the support bar 6 is different not only in that the length a of the lower end side is extended, but also that a pressing portion 6f is formed at the lower end. The pressing portion 6f has an outer diameter larger than the diameter of the guide hole 7e, and has a tapered shape that expands downward. Reinsertion of the portion 6f into the guide hole 7e is prevented, and the upper surface 7b of the bottom 7d is reliably pressed.
In order to achieve the above object, the pressing portion 6f may be provided with a slot 6g for imparting elasticity formed in the insertion / removal direction, if necessary.
[0028]
Next, a third embodiment will be described.
10 and 11 show a third embodiment.
The second embodiment is different from the first embodiment in that the cap 4 and the support bar 6 are not integrally connected with each other by a screw structure but are integrally formed.
That is, when the powdered tea 8 is filled in the middle cylindrical body 7, the lower end 6c of the support rod 6 is inserted into the guide hole 7e so that the powdered tea 8 does not fall out from the guide hole 7e of the bottom 7d of the storage portion 7a. While raising the cap 4, the powdered tea 8 is put into the storage section from the gap formed between the closed section 4e of the cap and the opening end 7i of the storage section 7a of the middle cylinder.
[0029]
Next, a fourth embodiment will be described.
FIG. 12 shows a fourth embodiment.
In the case of the second embodiment, the screw connection between the cap and the screw portion of the bottle mouth is an external screw system, whereas in this embodiment, the screw connection structure between the cap 4 and the middle cylinder 7 is an internal screw system. They differ in points. That is, the cap has a screw portion 4c formed on the outer peripheral surface 4f of the closing portion 4e, and the bottle mouth 2 has a screw portion 2d formed on the inner peripheral wall of the bottle mouth 2a.
[0030]
Although each of the above embodiments has been described with respect to the case where powdered tea is used as a powder component, the present invention is not limited to this, and is used as a plastic bottle in the case of coffee powder, juice powder or other flavoring material powder. It can also be implemented when used.
[0031]
【The invention's effect】
In claims 1 and 2,
As in the conventional example, it is not necessary to perform a troublesome operation of once removing the cap to mix the powdered tea with the drinking water, and once the cap is removed, the middle cylinder falls into the water. The powdered tea in the storage part can be mixed with drinking water without remaining in the same part.
[0032]
In addition, if the PET bottle is shaken in a state where the middle cylinder is dropped into the drinking water, the middle cylinder functions as a stirring member, and the powdered tea can be quickly and surely mixed with the drinking water.
In addition, since the cap and the support rod are screwed in, the powder tea can be put in the storage part with the cap open and the open end of the storage part opened, so that the powder tea can be filled. Easy to do.
[0033]
In addition, the powdered tea filled in the storage unit is normally closed at its upper end by the cap closing part and the bottom guide hole by the support rod in an airtight manner. The airtightness is maintained for a long time, and the powdered tea does not deteriorate.
In addition, since the storage portion of the middle cylindrical body that has fallen into the drinking water is mixed in a state where both the opening end and the guide hole are opened, the distribution of the drinking water is improved, and the powdered tea is left in the storage portion. do not do.
[0034]
Further, in claims 2 and 4,
At all times, the powdered tea in the storage section can be kept airtight, and at the time of removing the cap at the time of drinking, the middle cylinder can be dropped into the drinking water by the support rod, so that reliable mixing can be performed.
[0035]
In claim 3,
The support rod is easily detached from the guide hole, and conversely, after the detachment, the bottom portion of the guide hole can be accurately pressed, and the middle cylinder can be reliably dropped into the drinking water.
