【発明の属する技術分野】
本発明は、飲料、食品等を充填密封するプラスチックボトル、ガラスビン、チューブ等の容器、或いはパウチの注出用スパウトに用いる合成樹脂キャップに関し、特に容易に開口が可能で、また、開口時の感触、感覚が良好な合成樹脂キャップに関するものである。
【０００２】
【従来の技術】
従来、プラスチックボトル、ガラスビン、チューブ等の容器、或いはパウチの注出用スパウトから内容物を容易に取り出すために、合成樹脂キャップが各種飲料、食品等に多数用いられている。そして、この種の合成樹脂キャップにおいては、前記キャップを握り、手指で回転して開口を行う際の指掛かりが重要となり、特に子供、女性、高齢者は手指による開口力不足によって開口不良となるため、前記指掛かりが重要となる。
【０００３】
これに対し、図１２に例示するように、前記キャップのスカート部Ｓの外周面にローレット加工Ｒ等を施して指掛かりを容易にしたキャップ１１が多数提案されている。
【０００４】
一方、図１３乃至図１５に例示するように、キャップのスカート部Ｓの高さ方向のほぼ全高に突起部Ｐを対称的に二本設けて、開口時の指掛かりを容易にしたキャップ２１も提案されている。
【０００５】
【発明が解決しようとする課題】
しかしながら、ローレット加工Ｒをスカート部Ｓの外周面に施したキャップ１１は、その外周面が結露、湿気、水分等或いは汗で濡れると滑り易く、特に、前記キャップが小径の場合は、この傾向が顕著に現れる。一方、キャップ外周面の高さ方向のほぼ全高に突起部を対称的に二個設けたキャップは、前記突起部間の距離が大でキャップ開口時に滑り易い。そして、開口時の高さ方向における指掛かり位置も一定せず、突起部の上方でキャップを回転した場合は捻れ、撓み等の変形を生じて開口しづらく、また、突起部がキャップ外周面の上方にも設けられているため、開口時のキャップに対する手指のフィット感、握り易さ等に欠ける。また、前述したキャップ等の欠点は、特にその外径が小径の４０ｍｍ以下の主に指で開口するキャップの場合に顕著に現れる。さらに、図１２に例示するように、スカート部Ｓの下方にブリッジを介して連結されている不正開封防止用の環状リングＴを形成したキャップ、特に小径のキャップにおいては、開口時にスカート部Ｓと共に環状リングＴも指で握ってしまい、開口不良となる恐れもある。
【０００６】
【課題を解決するための手段】
本発明によれば、天板とスカート部から成り、前記スカート部の内面に螺子部を形成し、一方外面の高さ方向中央よりも下方部に、４個以上の突起部を等間隔に同じ突出量で形成し、前記突起部間を内方に湾曲する曲面部で連続的に連結した合成樹脂キャップが提供される。また、本発明の合成樹脂キャップにおいては、外径が４０ｍｍ以下であることが好ましい。また、本発明の合成樹脂キャップにおいては、前記突起部の上端部をテーパ状とすることが好ましい。また、本発明の合成樹脂キャップにおいては、前記突起部の外周面を曲面状とすることが好ましい。また、本発明の合成樹脂キャップにおいては、前記突起部の突出量を２乃至４ｍｍとすることが好ましい。また、本発明の合成樹脂キャップにおいては、前記スカート部の下方にブリッジを介して環状リングを連結することが好ましい。さらに、本発明の合成樹脂キャップにおいては、前記突起部が環状リングよりも突出していることが好ましい。
【０００７】
【発明の実施の形態】
本発明の合成樹脂キャップは、天板とスカート部から成り、該スカート部の内面に螺子部を形成し、一方外面の高さ方向中央よりも下方部に、個以上の突起部を等間隔に同じ突出量で形成し、前記突起部間を内方に湾曲する曲面部で連続的に連結することが特徴である。即ち、合成樹脂キャップにおいて前記構成とすることにより、螺子部と突起部間で梃子作用が働き、小さな開口力で容易に開口が行われ、また、開口時の指掛かりも確実に行われる。尚、前記突起部は等間隔に４個以上としたが、好ましくは４個乃至６個がキャップと手指のフィット感、握り易さ、開口時等の回転力の伝達の点で好ましい。また、突起部の間隔、突出量は、ほぼ等間隔、ほぼ同じ突出量でも良い。
【０００８】
本発明の合成樹脂キャップは、特に、飲料等のプラスチックボトル、金属製ボトル等の口部外径が比較的小径の場合に好適であって、前記キャップの外径が４０ｍｍ以下の場合に特に好適である。
【０００９】
本発明の合成樹脂キャップにおいては、前記突起部の上端部をテーパ状とすることが、開口時の該キャップの外周面に形成された突起部に対する指掛かりをスムーズに行う点で好ましい。
【００１０】
また、本発明の合成樹脂キャップにおいては、前記突起部の外周面を曲面状とすることが、さらに、開口時の該キャップの回転による手指の怪我防止、或いは手指への負担を軽減する点で好ましい。
【００１１】
また、本発明の合成樹脂キャップにおいては、前記突起部間を内方に湾曲する曲面部で連続的に連結することが、さらに、指掛かりのフィット感、及び回転力の伝達の点で好ましい。
【００１２】
また、本発明の合成樹脂製キャップにおいては、前記突起部の突出量を２乃至４ｍｍとすることが、指掛かり、回転力の伝達、手指のけが防止、材料の節減の点で好ましい。
【００１３】
また、本発明の合成樹脂キャップにおいては、前記スカート部の下方にブリッジを介して環状リングを連結することが、キャップによって内容物を密封した後の不正開封を確実に防止する点で好ましい。
【００１４】
さらに、本発明の合成樹脂キャップにおいては、前記突起部が環状リングよりも突出していることが、開口時にスカート部と共に環状リングを指で握ることにより生じる開口不良を防止する点で好ましい。
【００１５】

However, the cap 11 with the knurl R applied to the outer peripheral surface of the skirt portion S is easily slipped when the outer peripheral surface gets wet with condensation, moisture, moisture, or sweat, and this tendency is particularly noticeable when the cap has a small diameter. Appears prominently. On the other hand, a cap provided with two protrusions symmetrically at almost the entire height in the height direction of the outer peripheral surface of the cap has a large distance between the protrusions and is easily slipped when the cap is opened. Also, the position of the finger hook in the height direction at the time of opening is not constant, and when the cap is rotated above the protrusion, it is difficult to open due to deformation such as twisting and bending, and the protrusion is not on the outer peripheral surface of the cap. Since it is also provided on the upper side, it is lacking in the fit of fingers with respect to the cap at the time of opening, ease of gripping, and the like. Further, the above-described drawbacks of the cap and the like are prominent particularly in the case of a cap whose outer diameter is a small diameter of 40 mm or less and is mainly opened with a finger. Further, as illustrated in FIG. 12, in a cap formed with an annular ring T for preventing unauthorized opening, which is connected to the lower side of the skirt portion S via a bridge, particularly a small-diameter cap, together with the skirt portion S when opened. The annular ring T is also gripped with a finger, and there is a risk of opening failure.
