【０００５】
【発明が解決しようとする課題】
ところで、飲料水が入った飲料缶体は自動販売機等で販売されることから飲料缶の胴部の外径は略同じであるが、上端部の形状は製缶メーカーによって様々に形成されている。主要なものとして、例えば、幅広で且つ胴部と比べて外径が細くくびれた形状の幅広小径部が上端部に形成されている飲料缶体、上端部が胴部から階段状に小径となるようにくびれた形状の飲料缶体、或いは、幅狭で且つ胴部と比べて外径が細くくびれた形状の幅狭小径部が上端部に形成されている飲料缶体等が知られている。そのため、特許文献１に記載の技術では、このような飲料缶体の上端部の形状の違いに合わせてプレミアムケースを個別に設計及び製造しなくてはならないという問題がある。
【０００６】
この発明は、飲料缶体の上端部のくびれ形状が異なる飲料缶体に嵌着可能な飲料缶用キャップ及びキャップ付き飲料缶を提供することを目的とする。
【０００７】
【課題を解決するための手段】
この発明の飲料缶用キャップは、蓋部の外周縁に環状のリブを有する円筒形状の飲料缶体の前記蓋部に着脱可能に嵌着され、前記飲料缶体と略同径の円筒形の外周面を有し、前記蓋部に載置される景品を被蓋する飲料缶用キャップであって、下端面が開口し前記蓋部に嵌着可能な円筒状のキャップ主部と、このキャップ主部の下端内面から内側に突出して周方向に沿って延設された第１係止部と、前記第１係止部より上方の前記キャップ主部の内面から前記第１係止部よりも内側に向かって高く突出するように周方向に沿って互いに離間して延設された複数の第２係止部と、前記キャップ主部の内面を部分的に内側に突出させて肉厚にするように前記キャップ主部の上端から前記複数の第２係止部までそれぞれ延びた複数の肉厚部と、を具備しており、前記蓋部の外周縁に設けられたリブに前記第１係止部と第２係止部とのうちの一方を係合させることを特徴とする。
【０００８】
この発明の飲料缶用キャップによれば、キャップ主部の内面に周方向に沿って突出して設けられた第１係止部と、キャップ主部の内面で且つ第１係止部の上側に第１係止部よりも内側に向かって高く突出するように周方向に沿って設けられた第２係止部とを備えているので、第１係止部と第２係止部とのうちの一方を飲料缶体の上端部に係合させることで、飲料缶体に着脱自在に嵌着させることができる。
【０００９】
【発明の実施の形態】
以下、図１〜図１０を参照して本発明の一実施形態を説明する。
【００１０】
この実施形態の飲料缶用キャップ１は、例えば合成樹脂等による成形品であって、図１に示すように、キャップ主部２と、例えば４つの第１係止部３、及び、例えば４つの第２係止部５とを備えている。
【００１１】
キャップ主部２は、下端面が開口する円筒状をなしている。この実施形態では、例えば高さＨが３６ｍｍ、外径Ｒが５５ｍｍとなるように形成されている。キャップ主部２の内面には、周方向に沿うリブ状の４つの円弧状の第１係止部３が一体に設けられている。これら第１係止部３は、互いに角度が略９０°ずつずれた位置に配設されている。これら第１係止部３は、キャップ主部２の下縁に設けられている。
【００１２】
一方、キャップ主部２の内面には、互いに角度が略９０°ずつずれた位置、且つ、隣り合う第１係止部３の中間部となるように肉厚部４が形成されている。肉厚部４は、キャップ主部２の内側上面から３０ｍｍの位置まで下側に延びている。したがって、厚肉部４の下縁は、キャップ主部２の下縁よりも６ｍｍ上側に位置している。周方向に沿うリブ状の４つの円弧状の第２係止部５は、この肉厚部４の下縁に一体に設けられている。これら第２係止部５は、第１係止部３よりも上側に設けられているとともに、第１係止部３よりも内側に向かって高く突出するように形成されている。また、互いに対向する肉厚部４間の距離Ｌは４９ｍｍに形成されている。
【００１３】
なお、この実施形態は、円弧状の第１及び第２係止部３，５を４つずつ設けたが、円弧状の第１及び第２係止部３，５は夫々いくつ設けてもよい。また、第１及び第２係止部３，５は周方向に連続するように設けてもよい。
【００１４】
次に、飲料缶用キャップ１を第１の飲料缶体１１に着脱自在に嵌着してなる第１のキャップ付き飲料缶１０について説明する（図２〜図４参照）。例えばスチール製或いはアルミ製の第１の飲料缶体１１は、円筒状の筒体１２と、底部と蓋部とを形成する一対のカバー（蓋部となる上側のカバーのみ図示）１３とを備えている。筒体１２は、上端部に、幅広で且つ胴部と比べて外径が細くくびれた形状の幅広小径部１４が形成されている。缶体１１は、この筒体１２の上側開口と下側開口とにカバー１３をかしめて密閉構造に形成されており、その内部にコーヒー等の飲料水が収容されている。また、このように筒体１２にカバー１３をかしめて密閉するので、缶体１１の上端及び下端には、その周方向に沿って連続する上端リブ１５及び下端リブ１６が形成される。
【００１５】
上側のカバー１３には、図示しないが、注出口が形成されており、この注入口の内側の領域が押込み式の蓋部となっている。この蓋部の上にタブが取付けられ、このタブを上側に引き上げて蓋部を下方に押込むことにより、注出口を開放できるようになっている。この実施形態では、胴部の外径Ｒ１が５２．８ｍｍ、幅広小径部１４の外径Ｒ２が５０．５ｍｍ、上端リブ１５の外径Ｒ３が５２．２ｍｍとされている。
【００１６】
飲料缶用キャップ１は、その下端側の開口部を缶体１１の上端部に対応させて押込むことで、この缶体１１に着脱自在に取付けることができる。詳しくは、飲料缶用キャップ１を上方から下方へ押込むことにより、図３に示すように、第１係止部３が上端リブ１５を弾性的に乗り越えてその下側に係合し、この係合で飲料缶用キャップ１は缶体１１に対して嵌着保持される。なお、飲料缶用キャップ１を缶体１１に嵌着させた際、図４に示すように、第２係止部５が缶体１１の上面よりも若干上方或いはこの上面に接するように、第２係止部５を缶体１１の上方に配置しているので、第１係止部３と上端リブ１５との係止の邪魔にならない。この実施形態では、飲料缶用キャップ１を缶体１１に嵌着させた状態における飲料缶用キャップ１の内側上面と缶体１１の上端リブ１５との間ｈ１が３０ｍｍ、飲料缶用キャップ１内容積（飲料缶用キャップ１と第１の飲料缶体１１の上面とにより囲まれた領域）が約５６．４ｃｍ２となる。一方、この状態から、飲料缶用キャップ１を上方に引き上げることで、第１係止部３と上端リブ１５との係合が外れるので、飲料缶用キャップ１を缶体１１から取外すことができる。
【００１７】
したがって、この第１の飲料缶１０によれば、第１の飲料缶体１１の蓋部となる上側のカバー１３の上面に景品Ｐを載置し、飲料缶用キャップ１を上述のように取付けて缶体１１を上方から被蓋することで、飲料缶用キャップ１の内部（飲料缶用キャップ１と第１の飲料缶体１１の上面とにより囲まれた領域）に景品Ｐを収納することができる。また、消費者は、第１の飲料缶１０を購入後、飲料缶用キャップ１を上述のように缶体１１から取外すことで景品Ｐを取り出すことができる。また、飲料缶用キャップ１を取外した後は、タブを引き上げて注出口を開放することで、缶体１１内の飲料水を飲むことができる。
【００１８】
飲料缶用キャップ１を第２の飲料缶体２１に着脱自在に嵌着してなるキャップ付き第２の飲料缶２０について説明するが、基本的には第１の飲料缶１０と同一構造であり、同一構成部分は同一番号を付して説明を省略する（図５〜図７）。例えばスチール製或いはアルミ製の第２の飲料缶体２１の筒体２２は、上端部が胴部から階段状に小径となるようにくびれた形状の小径部２４が形成されている。この実施形態では、胴部の外径Ｒ４が５２．８ｍｍ、上端リブ２５の外径Ｒ５が４８．１ｍｍとされている。つまり、缶体２１の上端リブ２５の外径Ｒ５は缶体１１の上端リブ１５の外径Ｒ３と比べて４．２ｍｍも小さいことになる。そのため、飲料缶用キャップ１の第１係止部３は缶体２１の上端リブ２５に係合しないが、飲料缶用キャップ１は、その下端側の開口部を缶体２１の上端部に対応させて押込むことで、第２係止部５を缶体２１の上端リブ２５に係合させてこの缶体２１に着脱自在に取付けることができる。
【００１９】
詳しくは、飲料缶用キャップ１は上方から下方への押込みにより、図７に示すように、第２係止部５が上端リブ２５を弾性的に乗り越えてその下側を係合し、この係合で飲料缶用キャップ１は缶体２１に対して嵌着保持される。このとき、第２係止部５は２段の階段状の小径部２４の内の上段部２４ａに位置する。また、図６に示すように、第１係止部３は２段の階段状の小径部２４の下段部２４ｂに位置するため、第２係止部５と上端リブ２５との係止の邪魔にならない。この実施形態では、飲料缶用キャップ１を缶体２１に嵌着させた状態における飲料缶用キャップ１の内側上面と缶体２１の上端リブ２５との間ｈ２が２５ｍｍ、飲料缶用キャップ１内容積（飲料缶用キャップ１と第２の飲料缶体２１の上面とにより囲まれた領域）を約４７ｃｍ^２となる。
【００２０】
飲料缶用キャップ１を第３の飲料缶体３１に着脱自在に嵌着してなるキャップ付き第３の飲料缶３０について説明するが、基本的には第１の飲料缶１０と同一構造であり、同一構成部分は同一番号を付して説明を省略する（図８〜図１０参照）。例えばスチール製或いはアルミ製の第３の飲料缶体３１は、上端部に、幅狭で且つ胴部と比べて外径が細くくびれた形状の幅狭小径部３４が形成されている。この実施形態では、上端リブ３５の外径Ｒ６が５２．３ｍｍとされている。
【００２１】
飲料缶用キャップ１は、その下端側の開口部を缶体３１の上端部に対応させて押込むことで、缶体１１と同様に着脱自在に取付けることができる。詳しくは、飲料缶用キャップ１は押込みにより、図９に示すように、第１係止部３が上端リブ３５を弾性的に乗り越えてその下側を係合し、この係合で飲料缶用キャップ１は缶体３１に対して嵌着保持される。なお、飲料缶用キャップ１を缶体３１に嵌着させた際、図１０に示すように、第２係止部５が缶体３１の上面よりも若干上方或いはこの上面に接するように、第２係止部５を缶体１１の上方に配置しているので、第１係止部３と上端リブ３５との係止の邪魔にならない。この実施形態では、飲料缶用キャップ１を缶体３１に嵌着させた状態における飲料缶用キャップ１の内側上面と缶体３１の上端リブ１５との間ｈ３は３０ｍｍ、飲料缶用キャップ１内容積（飲料缶用キャップ１と第３の飲料缶体３１の上面とにより囲まれた領域）を約５６．４ｃｍ^２となる。
【００２２】
以上のように、この実施形態では、キャップ主部２の内面に周方向に沿って設けられた第１係止部３と、キャップ主部２の内面且つ第１係止部３の上側に第１係止部３よりも内側に向かって高く突出するように周方向に沿って設けられた第２係止部５とを備えているため、缶体１１，２１，３１の上端リブ１５，２５，３５のくびれ形状によって、第１係止部３と第２係止部５とのうちの一方を上端リブ１５，２５，３５に係合させて缶体１１，２１，３１に着脱自在に嵌着させることができる。また、この実施形態によれば、内部に飲料水が収容され上側のカバー１３の上面に載置された景品を包容するように、この飲料缶用キャップ１を飲料缶体１１，２１，３１に着脱自在に嵌着させることで、キャップ付き飲料缶１０，２０，３０が得られる。
【００２３】
