Description

【0001】
【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つ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、吸収能力付与容器としては、特開平9−12064号公報の乾燥能力を有する容器が知られている。この容器は、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ものであった。
【0003】
【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。
【0004】
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。
【0005】
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、また、バージン性が付与可能な吸収能力付与容器を提供するものである。
【0006】
【課題を解決するための手段】
すなわち、本発明の第1の発明は、容器本体にヒンジ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、前記外側容器は、前記容器本体の周壁の上面に、前記蓋との咬合リングを上端外周面にもつ薄肉の蓋嵌着筒を立設し、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、前記蓋の周壁の内周面に、前記容器本体との咬合リングを設け、天板下面に、前記容器本体の前記蓋嵌着筒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、この蓋嵌着筒との封止リングの内側に、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、前記内側容器は、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。
【0007】
そして、本発明の第2の発明は、前記内側容器の周壁天面に、封止シートを剥離可能に接着して、上方の開口部を封止したことを特徴とする第1の発明に記載の吸収能力付与容器である。
【0008】

【0009】
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。
【0010】
また、本発明の吸収能力付与容器は、外側容器の容器本体に蓋を嵌着したときに、従来の吸収能力付与容器とは異なり、図2に示すように、容器本体(110)の蓋嵌着筒(115)の上端外周面に設けられた咬合リング(116)に、蓋(120)の周壁(124)の内周面に設けられた咬合リング(125)が咬合するだけでなく、蓋の天板(121)下面に設けられた封止リング(122)の先端部外周面が、容器本体の薄肉で柔軟性をもつ蓋嵌着筒(115)の上端内側角部に密接し、さらに、この蓋嵌着筒との封止リング(122)の内側の天板下面に設けられている封止リング(123)の先端部外周面が、内側容器の周壁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。
【0011】
