【発明の属する技術分野】
本発明は、内容物を保護するために、容器内の水分やガスを吸収する能力をもち、乳幼児が容易に開けることができないチャイルドレジスタント(Child Resistant) 機能を有するプラスチック製の吸収能力付与容器に関するものである。
【０００２】
【従来の技術】
従来の吸収能力付与容器としては、容器本体内に乾燥剤含有熱可塑性プラスチックで作られたディスク形状やライナー形状の挿入物を射出成形法により一体に熱融着して形成した容器が知られている（例えば、特許文献１参照。）。

【０００４】
【発明が解決しようとする課題】
しかしながら、上述の従来の吸収能力付与容器は、容器本体内に乾燥剤含有熱可塑性プラスチックの挿入物が熱融着して一体に接着しているため、挿入物が容器内の水分だけでなく容器外の水分も吸収してしまい吸収能力が低下することがあった。また、容器本体を成形する熱可塑性樹脂と挿入物を成形する乾燥剤含有熱可塑性樹脂とは、相互に熱融着し合う材質のものでなくてはならず、自ずと使用できる熱可塑性樹脂が限定された。また、挿入物の容器内の水分の吸収は、挿入物の容器内面側だけであり、場合によっては、吸収能力が不足することもあった。
【０００５】
また、上述の従来の吸収能力付与容器は、容器本体の周壁の上端部外周面に咬合リングを設け、この咬合リングに、蓋部の内周面に設けた咬合リングを咬合させて嵌着及び密封していた。このため、蓋部の開閉にともない咬合リングに傷が付くと、容器の密封性が低下することがあった。
【０００６】
なお、近年、乳幼児による内容物の誤飮事故が、内外のニュースに報じられ、内容物によっては死に至ることもあり、乳幼児が容易に開けられない容器が求められることがあった。
【０００７】
本発明は、上述の従来の吸収能力付与容器を解決したものであり、容器内の水分やガスの吸収能力が高く、外側容器及び内側容器に使用する熱可塑性樹脂を任意に選べ、密封性が高く、バージン性が付与可能で、また、乳幼児が容易に開けることができない吸収能力付与容器を提供するものである。
【０００８】
すなわち、本発明の第１の発明は、容器本体の後方部にヒンジ部を介して蓋が開閉するプラスチック製の外側容器の内側に、吸収物質を含有する熱可塑性樹脂からなる上方が開口する内側容器を、前記外側容器の容器本体に係着して収容した容器であって、前記内側容器は、周壁と底板とからなり、周壁外周面に、前記外側容器の周壁内周面と先端が当接する縦筋状のローレット目を設け、底板下面に、外周縁部から中心方向への脚リブを周方向に等間隔で放射状に複数本設けたことを特徴とする吸収能力付与容器である。
【０００９】
次に、本発明の第２の発明は、容器本体の後方部にヒンジ部を介して蓋が開閉するプラスチック製の外側容器の内側に、吸収物質を含有する熱可塑性樹脂からなる上方が開口する内側容器を、前記外側容器の容器本体に係着して収容した容器であって、前記容器本体の周壁の上端部に、その前方上端部に前記蓋の開閉用小蓋との嵌合突部をもち該嵌合突部の後方の上端外周面に前記蓋との咬合リングをもつ薄肉の蓋嵌着筒を立設し、前記上端部内周面に、前記内側容器を係着する係着突起を設け、前記蓋の前記ヒンジ部の対向側の前方部に、天板の左右方向のヒンジ線と該ヒンジ線の両端に接続し天板から周壁下端に至る前後方向の平行な２本の切り目線とにより形成され周壁に前記容器本体の嵌合突部との嵌着窓を有する前記開閉用小蓋を設け、該開閉用小蓋の後方の周壁の内周面に、前記容器本体との咬合リングを設け、前記開閉用小蓋の後方の天板下面に、前記内側容器の周壁の上端内側角部と先端部外周面を密接する封止リングを垂設した前記外側容器と、周壁と底板とからなり、周壁外周面に、前記外側容器の周壁内周面と先端が当接する縦筋状のローレット目を設け、底板下面に、外周縁部から中心方向への脚リブを周方向に等間隔で放射状に複数本設けた前記内側容器とから構成されることを特徴とする吸収能力付与容器である。
【００１０】
そして、本発明の第３の発明は、容器本体の後方部にヒンジ部を介して蓋が開閉するプラスチック製の外側容器の内側に、吸収物質を含有する熱可塑性樹脂からなる上方が開口する内側容器を、前記外側容器の容器本体に係着して収容した容器であって、前記容器本体の周壁の上端部に、その前方上端部に前記蓋の開閉用小蓋との嵌合突部をもち該嵌合突部の後方の上端外周面に前記蓋との咬合リングをもつ薄肉の蓋嵌着筒を立設し、前記上端部内周面に、前記内側容器を係着する係着突起を設け、前記蓋の前記ヒンジ部の対向側の前方部に、天板の左右方向のヒンジ線と該ヒンジ線の両端に接続し天板から周壁下端に至る前後方向の平行な２本の切り目線とにより形成され周壁の内周面下方に前記容器本体の嵌合突部との嵌着突部を有する前記開閉用小蓋を設け、該開閉用小蓋の後方の周壁の内周面に、前記容器本体との咬合リングを設け、前記開閉用小蓋の後方の天板下面に、前記内側容器の周壁の上端内側角部と先端部外周面を密接する封止リングを垂設した前記外側容器と、周壁と底板とからなり、周壁外周面に、前記外側容器の周壁内周面と先端が当接する縦筋状のローレット目を設け、底板下面に、外周縁部から中心方向への脚リブを周方向に等間隔で放射状に複数本設けた前記内側容器とから構成されることを特徴とする吸収能力付与容器である。
【００１１】
【作用】
本発明の吸収能力付与容器（１０）は、図１（ａ）又は図３（ａ）に示すように、内側容器（２００）の外周面に図５（ａ）及び（ｂ）に示すローレット目（２１２）を設け、このローレット目の先端を外側容器（１００）の内周面に当接させて、また、内側容器の底板（２１３）下面に図５（ｂ）に示す放射状の複数本の脚リブ（２１４）を設け、この脚リブの下面を外側容器の底板（１１２）上面に当接させて、外側容器の内側に内側容器を係着して収容したものであり、前述した従来の外側容器の内面に挿入物の内面が一体に接着する吸収能力付与容器のように、容器内の水分やガスを挿入物の内面だけで吸収するものとは異なり、内側容器の内面とローレット目を設けた外面及び脚リブを設けた底板下面とで吸収できるため、吸収する表面積が広く、容器内の水分やガスの吸収能力が高い。
【００１２】
また、本発明の吸収能力付与容器は、外側容器の内側に別途作製した内側容器を係着して収容したものであり、従来の吸収能力付与容器のように、外側容器の内面と内側容器の外面とを熱融着して一体に作製する必要がないため、外側容器及び内側容器に使用する熱可塑性樹脂には、それぞれ任意の熱可塑性樹脂を使用することができる。
【００１３】
また、本発明の吸収能力付与容器（１０）は、図１（ｂ）又は図３（ｂ）に示すように、外側容器の容器本体（１１０）に蓋（１２０）を嵌着したときに、従来の吸収能力付与容器とは異なり、図１（ａ）又は図３（ａ）に示すように、外側容器（１００）の容器本体（１１０）の蓋嵌着筒（１１５）の前方上端部の嵌合突部（１１７）に、蓋（１２０）の開閉用小蓋（１３０）の嵌着窓（１３３）又は嵌着突部（１３４）が嵌合し、同時に、容器本体の蓋嵌着筒の嵌合突部の後方の上端外周面の咬合リング（１１６）に、蓋の開閉用小蓋の後方の咬合リング（１２６）が咬合し、さらに、蓋の天板（１２１）下面に設けられた封止リング（１２４）の先端部外周面が、内側容器（２００）の周壁（２１１）の上端内側角部に密接して内側容器の開口部を封止するため、容器の密封性が極めて良好である。
【００１４】
また、図６（ｂ）に示すように、内側容器（２００）の周壁（２１１）天面に封止シート（３００）を剥離可能に接着して封止した本発明の吸収能力付与容器は、使用するときに、封止シートを剥離して内側容器を開封するまでは、容器のバージン性を確保することができる。
【００１５】
また、本発明の吸収能力付与容器（１０）は、容器を開封するときには、まず、図２又は図４に示すように、指で蓋（１２０）の開閉用小蓋（１３０）を天板（１２１）のヒンジ線（１２３）を支線として前方部を上方へ持ち上げて（２点鎖線で示す）、開閉用小蓋の嵌着窓（１３３）又は嵌着突部（１３４）を、容器本体（１１０）の蓋嵌着筒（１１５）の嵌合突部（１１７）から外して開け、さらに、開けた開閉用小蓋により蓋を容器本体と接続する後方のヒンジ部を支線として後方へ半回転して、図１（ａ）又は図３（ａ）に示す蓋（１２０）の開閉用小蓋（１３０）の後方の咬合リング（１２６）を、容器本体（１１０）の蓋嵌着筒（１１５）の嵌合突部の後方の上端外周面の咬合リング（１１６）から外して容器を開封するものである。このように、容器の開封は２段階であり、本発明の吸収能力付与容器は、乳幼児が容易に開けることができない。
