Abstract
Description
しかしながら、上記従来の包装体において蓋材の開閉を繰り返すと、蓋材の粘着面に薬液やゴミが付着して粘着力が低下するため、蓋材が自動的に剥がれてしまう虞がある。また、蓋材の粘着力の低下に伴いシール性も低下するため、包装体内部の気密性が低下してしまう虞もある。
特に、特許文献1の技術は、枠体には表面側に突出するフランジ部(突起部)が開口部に沿って周設され、開閉蓋部にはその裏面側に突起部に嵌合する凹状部(嵌合部)が周設されているので、包装体内部の気密性を確保しつつ、外部からの空気又は埃などの侵入を防ぐことができる。
また、ともに直立している突起部と嵌合部との干渉を極力減らすべく、嵌合部を平面視略C状の内立壁と外立壁とにより形成し、当該内立壁と外立壁の略C状の開放部同士が重ならないように、略C状の開放部に対向した位置にそれぞれ内立壁又は外立壁が配設されるようにしている。
ウェットシート包装体の袋本体に取り付けられるウェットシート包装体用蓋体であって、
前記袋本体の上面に設けられた開口部を外方から囲繞する蓋開口部が形成された枠体と、
前記枠体の一端部にヒンジ部を介して回動自在に連結されるとともに当該枠体の表面側から前記蓋開口部を閉塞する開閉蓋部と、を備え、
前記枠体及び前記開閉蓋部のうち何れか一方には、当該開閉蓋部の裏面側又は当該枠体の表面側に突出する突起部が周設され、
前記枠体及び前記開閉蓋部のうち何れか他方には、当該開閉蓋部の裏面側又は当該枠体の表面側に突出して前記突起部と嵌合する嵌合部が周設され、
前記嵌合部は、内壁部と、外壁部と、前記内壁部及び前記外壁部の間に形成された溝部と、により形成され、
前記蓋開口部と前記ヒンジ部が最も近接した位置における、前記突起部と前記ヒンジ部との距離は、前記突起部と前記嵌合部の重なり高さの5倍以上であることを特徴とする。
前記内壁部には、前記上端部が内側に向けて湾曲し、前記突起部を前記溝部に案内する案内部が形成され、
前記外壁部は、前記枠体又は前記開閉蓋部の短手方向の両端部の長手方向の中央部が切り欠かれて開放されていることを特徴とする。
前記開閉蓋部の短手方向の前記ヒンジ部と接続されていない側の端部に設けられた摘み部と、
前記枠体の短手方向の前記ヒンジ部と接続されていない側の端部に設けられ、前記摘み部を係止する係止部と、
前記枠体の短手方向の前記ヒンジ部と接続されていない側の端部に前記係止部を挟んで設けられた押さえ部と、
を備えることを特徴とする。
前記開閉蓋部に周設される前記突起部又は前記嵌合部の内部は、当該開閉蓋部の短手方向の剛性が、当該開閉蓋部の前記突起部又は前記嵌合部の周囲の部分と比較して高くなるように形成されていることを特徴とする。
上面に開口部が設けられた袋本体と、前記開口部を開閉自在に覆う蓋材と、を備える包装体と、
前記袋本体の上面に取り付けられる請求項1~4のいずれか一項に記載のウェットシート包装体用蓋体と、
を備えることを特徴とする。
包装体30は、袋本体10の内部にウェットシートSが複数枚積層された状態で収納され、開口部11からウェットシートSが1枚ずつ取り出されて使用される。
なお、以下の説明では、包装体30において、開口部11が形成された面を上面、開口部11が形成された面と反対側の面を底面とする。
また、袋本体10を構成するシート材は、袋本体10の底面側(図示略)で袋本体10の長手方向に沿って接合されるとともに、袋本体10の長手方向の両端部で対向する面同士が接合されている。
また、蓋材20の裏面には、ポリエステル系、アクリル系、ゴム系等の感圧接着剤が塗布されており、蓋材20は、開口部11を開閉自在に覆うように袋本体10に接着されるようになっている。
なお、ウェットシートSは、紙で形成されていてもよい。
蓋体100は、例えば、ポリエチレン(PE)、ポリプロピレン(PP)、ポリエチレンテレフタラート(PET)、ポリアミド(PA)等の熱可塑性樹脂で形成されている。
蓋体100は、袋本体10の開口部11を閉塞するものであり、図1及び図2に示すように、開口部11及び蓋材20を外方から囲繞する蓋開口部111が形成された枠体110と、枠体110に開閉自在に設けられるとともに枠体110の表面側から蓋開口部111を閉塞する開閉蓋部120と、開閉蓋部120を枠体110に回動自在に連結させるヒンジ部130と、を備えて構成され、これらは一体的に形成される。また、開閉蓋部120の肉厚は、0.5~2.0mm程度であり、樹脂の使用量低減や柔らかな使用感を得るという観点から、1.0mm以下とすることが好ましい。
枠体110には、表面側に突出する嵌合部112が、蓋開口部111に沿って周設されている。
嵌合部112は、図2、図4及び図5に示すように、平面視略楕円形状の内壁部113及び外壁部114と、内壁部113及び外壁部114の間に形成された溝部115と、により形成されている。この溝部115に、開閉蓋部120に設けられた突起部121が嵌合する(図4及び図5参照)。なお、図4及び図5は、開閉蓋部120を閉めた状態、即ち、溝部115に突起部121が嵌合した状態における断面図をそれぞれ示している。
また、蓋開口部111とヒンジ部130が最も近接した位置における突起部121とヒンジ部130の距離Lは、突起部121と嵌合部112の重なり高さHの5倍以上、好ましくは10倍以上である。このように、突起部121とヒンジ部130の距離を十分取ることにより、開閉蓋部120を開閉する際の突起部121と外壁部113との干渉を減らすことができる。
なお、図示例においては、蓋開口部111は、枠体110の短手方向中央部に設けられているが、短手方向においてヒンジ部130から離間する方向に偏った位置に設けると、蓋体100の限られた寸法を有効に活用できるため、より好ましい。或いは、図1に示すように、ヒンジ部130を蓋体100の外周から突出するように設けるのも、距離Lを大きく取るために好ましい形態の一つである。
外壁部114は、枠体110の短手方向の両端部の長手方向中央部が切り欠かれて開放されている。
また、枠体110の短手方向の他端部には、係止部117を挟んでそれぞれ1つずつ押さえ部116、116が設けられている。
押さえ部116、116は、枠体110から水平に突出した平面板形状であるが、使用者が指で下方に押さえることができる形状であれば、いかなる形状に形成されていてもよい。
本実施形態に係る開閉蓋部120は、上述のように肉薄とするのが好ましいが、その場合、蓋体100を開ける際に、使用者が開閉蓋部120の中央部(突起部121の内部)を指(例えば、左手の中指)で下方に押さえつつ、開閉蓋部120の摘み部123を他の指(例えば、左手の親指)で押し上げようとすると、開閉蓋部120の中央部が下方向に変形することにより、短手方向両端部の突起部121の先端部分が外方に向けて変形し、外壁部114と干渉するため、開閉蓋部120が開くことの妨げとなる。本実施形態のように、押さえ部116、116が設けられていると、開閉蓋部120の中央部が押さえられることが少なくなるため、突起部121と外壁部114との干渉を避けることができる。
突起部121の内部には、開閉蓋部120の短手方向に延在する2本のリブ(補強部)122、122が形成されている。これにより、開閉蓋部120の突起部121の内部の剛性が、突起部121の外部の剛性よりも高くなっている。なお、形成されるリブ122、122の本数は2本に限定されるものではなく、1本でもよいし、3本以上形成するようにしてもよい。或いは、開閉蓋部120の突起部121の内部の肉厚を、突起部121の外部の肉厚よりも10~100%程度厚くしてもよいが、リブ122を設ける方が樹脂の使用量を低減できるためより好ましい。
このように、開閉蓋部120の突起部121の内部の剛性が、突起部121の外部の剛性よりも高くなっていると、蓋体100を開ける際に、使用者が開閉蓋部120の中央部(突起部121の内部)を指(例えば、左手の中指)で下方に押さえたとしても、開閉蓋部120の中央部が下方向に変形しにくいため、突起部121と外壁部114との干渉を軽減することができる。
まず、使用者は、蓋体100の開閉蓋部120が閉められた状態(図2参照)から、枠体110の押さえ部116を指(例えば、左手の中指)で下方に押さえつつ、開閉蓋部120の摘み部123を他の指(例えば、左手の親指)で押し上げる。これにより、枠体110の係止部117に形成された突部117aと、摘み部123に形成された係止片部123aとの係合状態を解放し、開閉蓋部120を開ける。このとき、枠体110の嵌合部112の溝部115に嵌合された開閉蓋部120の突起部121は、外方に弧を描くように上方へと移動するが、上述のように突起部121とヒンジ部130の距離を十分取ることができているため、突起部121と外壁部114との干渉を減らすことができる。また、外壁部114の短手方向の両端部の中央部が開放されているため、突起部121と外壁部114との干渉をさらに減らすことができる。また、内壁部113に案内部113aが形成されているため、突起部121が案内部113aに案内されて溝部115と嵌合することとなって、突起部121と内壁部113との干渉を減らすことができる。
次に、使用者は、袋本体10の開口部11を覆う蓋材20を剥離して開口部11を表出させる(図1参照)。なお、本実施形態では、開閉蓋部120が開口部11の蓋として機能するため、蓋材20は必ずしも必要ではなく、予め蓋材20を剥離して廃棄するようにしてもよい。
次に、使用者は、開口部11を介して、包装体30の内部に複数枚積層された状態で収納されているウェットシートSを摘みながら上方に引き出すことによりウェットシートSを取り出して、汚れた手や顔などを清拭する。
使用後は、開口部11を覆うように蓋材20を再接着した後、開閉蓋部112を閉めることにより、包装体30の内部を再度密封する。なお、蓋材20を廃棄している場合は、開閉蓋部112を閉める作業のみを行う。このとき、溝部115に突起部121が嵌合されるとともに、突部117aと係止片部123aとが係合される。溝部115に突起部121が嵌合される際、突起部121とヒンジ部130の距離を十分取ることができているため、突起部121と外壁部114との干渉を減らすことができる。また、外壁部114の短手方向の両端部の中央部が開放されているため、突起部121と外壁部114との干渉をさらに減らすことができる。また、内壁部113に案内部113aが形成されているため、突起部121と内壁部113との干渉を減らすことができる。
従って、本実施形態に係る蓋体100によれば、突起部121が溝部115に嵌合することで、包装体30の開口部11を閉塞することができるので、包装体30内部の気密性を確保することができる。
また、本実施形態に係る蓋体100によれば、蓋開口部111とヒンジ部130が最も近接した位置における、突起部121とヒンジ部130の距離Lは、突起部121と嵌合部112の重なり高さHの5倍以上であるため、突起部121とヒンジ部130の距離を十分取ることができ、開閉蓋部120を開閉する際の突起部121と内壁部113及び外壁部114との干渉を減らすことができる。即ち、本実施形態に係る蓋体100によれば、開閉蓋部120の開閉動作をスムーズに行うことができる。
また、本実施形態に係る蓋体100によれば、枠体110の短手方向のヒンジ部130と接続されていない側の端部に、係止部117を挟んで設けられた押さえ部116、116を備えているので、使用者はこの押さえ部116、116を指で下方に押さえることにより、枠体110を下方に押さえた状態で開閉蓋部120を開けることができることとなって、開閉蓋部120の開閉作業を容易に行うことができる。また、開閉蓋部120の中央部が押さえられることが少なくなるため、突起部121と外壁部114との干渉を避けることができる。
また、上記実施形態では、摘み部123に係止片部123aを形成した構成を例示して説明しているが、これに限定されるものではない。即ち、摘み部123は、使用者が指で摘むことが可能であり、且つ係止部117に係止可能な構成であれば、いかなる構成であってもよい。
