Description
本発明は吸収用品に関するもので、より詳細には、種々の女性疾患を効果的に予防すると共に、通気性、肌触りや着心地に優れ、月経血や尿などを安全に吸収/保持できるので、月経血や尿などが吸収用品の幅方向に漏れることを効果的に防止することができる吸収用品に関するものである。
以下、本発明では遺伝子組み換え(GMO)を経ていない自然のままである綿の種子を使用し、合成肥料、殺虫剤及び農薬を使用せず栽培した綿を「オーガニックコットン」と呼ばれ、生理用ナプキンとおむつを総括して「吸収用品」と呼ばれる。
吸収用品の一例である生理用ナプキンは月経血のような女性の分泌物を吸収して収容することができる分泌物吸収パッドであって、従来の生理用ナプキンは基本的に、上部カバー層、吸収パッド及び下部カバー層が順に積層されており、生理用ナプキンの両側面に翼部が形成された構造である。上部カバー層は皮膚と直接接触して月経血や膣分泌物を吸収パッドなどに通過させる役割をし、吸収パッドは月経血を直接吸収して保持する役割をし、下部カバー層は月経血が漏れないように防ぐ防水層の役割を行うようになる。
従来の生理用ナプキンとしては、特許文献1等に記載されているように、吸収パッドを合成繊維不織布、パルプ及び高分子吸収体で形成し、上部カバー層をポリプロピレンなどの合成繊維不織布で形成した生理用ナプキンが主に使用されてきた。しかし、高分子吸収体、合成繊維不織布の使用によって、通気性、肌触りや着心地が低下することは勿論、種々の女性疾患を引き起こす問題が発生した。また、月経血漏れ防止線が実質的に形成されていないため、月経血の漏れを効果的に遮断することができない問題もある。
また他の従来の生理用ナプキンとしては、吸収パッドの輪郭線に沿って凹溝からなった複数の月経血漏れ防止線を形成した生理用ナプキンが使用されている。しかし、この月経血漏れ防止線によっては月経血が吸収パッドの幅方向に漏れることを効果的に防止することが難しい問題がある。
本発明の目的は、種々の女性疾患を効果的に予防することができ、着心地や肌触りに優れ、通気性にも優れており、月経血や尿などを迅速に吸収して安全に保持することができ、月経血や尿の漏れも効果的に遮断することができる吸収用品を提供するものである。
前述したような目的を達成するために、本発明の一様態によれば、吸収用品に含まれて月経血や尿を吸収/保持する役割を行う吸収パッドであって、木材パルプウェブ(Web)12bと、この木材パルプウェブ12b上に積層され、綿からなった不織布12aで構成され、不織布12aの表面には長手方向に沿って連続的に形成された谷部分(Valley part)が幅方向に沿って一定の間隔で形成されている吸収パッド12を使用して製造した吸収用品を提供する。
本発明の吸収用品によれば、吸収パッド12層をなす綿(Cotton)素材の不織布12aの表面に長手方向に沿って連続的に形成された谷部分が幅方向に沿って一定の間隔で配列されて、吸収パッド12の長手方向チャネルCを形成するので、吸収用品の幅方向に月経血や尿などが漏れる現象を効果的に防止することができる。
また、本発明の吸収用品によれば、吸収パッド12に綿からなった不織布12aと共に木材パルプウェブ12bが含まれているので、月経血や尿などを迅速に吸収して安全に保持することができる。
また、本発明の吸収用品によれば、吸収パッド12を構成する不織布12aが綿素材で構成されるので、種々の女性疾患を効果的に予防することができ、優れた通気性、肌触りや着心地を提供することができる。
以下、添付した図面等を参照して本発明を詳細に説明する。
本発明の吸収用品は図1に示すように、木材パルプウェブ12bと、この木材パルプウェブ12b上に積層され、綿からなった不織布12aで構成され、この不織布12aは表面に長手方向に沿って連続的に形成された谷部分が幅方向に沿って一定の間隔で形成されている吸収パッド12を含むことを特徴とする。
本発明の吸収用品は図1に示すように、木材パルプウェブ12bと、この木材パルプウェブ12b上に積層され、綿からなった不織布12aで構成され、この不織布12aは表面に長手方向に沿って連続的に形成された谷部分が幅方向に沿って一定の間隔で形成されている吸収パッド12を含むことを特徴とする。
吸収用品は生理用ナプキンやおむつなどであり得る。
吸収パッド12を構成する不織布12aは綿、より好ましくは、オーガニックコットンからなり、不織布12aは吸収用品の幅方向に沿って月経血や尿が漏れることを防止する側面から圧着処理した圧着不織布の形態であることが好ましい。
一実施形態として、本発明に係る生理用ナプキンは図2に示すように、一字状本体10及び、この一字状本体10の両側辺にそれぞれ形成された翼部20で構成される。
一字状本体10は、(i)防水フィルムからなる下部カバー層11、(ii)木材パルプウェブ12bと、この木材パルプウェブ12b上に積層され、綿からなった不織布12aとから構成された吸収パッド12、及び(iii)綿からなる不織布の形態である上部カバー層13で構成される。
図1及び図3に示すように、吸収パッド12を構成する不織布12aは、その表面に長手方向に沿って連続的に形成された谷部分が幅方向に沿って一定の間隔で形成された構造を有する。
図3に示すように、吸収パッド12をなす不織布12aと上部カバー層13との間には谷部分によってチャンネル(Chennel)Cが形成される。その結果、月経血が吸収パッド12の幅方向に濡れず、長手方向に沿って流れながら吸収される。
不織布12aは綿の単繊維が積層されたウェブ(Web)をニードルパンチングの方法で交絡させた後、カレンダロールなどを使用して圧着させた圧着不織布であることが好ましい。
下部カバー層11は合成樹脂フィルム又は生分解性フィルムなどからなり、使用後の廃棄時に環境汚染を最小化する側面から生分解性フィルムであることが好ましい。
吸収パッド12をなす不織布12aと上部カバー層13は綿素材のみでなった不織布素材で形成されているので、種々の女性疾患を予防する効果が非常に優れていると共に、着心地、肌触りや通気性にも優れている。
本発明の吸収用品は吸収パッド12をなす綿の不織布12aの表面に長手方向に沿って連続的に形成された谷部分が幅方向に沿って一定の間隔で配列されて、吸収パッド12の長手方向にチャンネルCを形成するので、吸収用品の幅方向に沿って月経血が漏れる現象を効果的に防止することができる。
また、本発明の吸収用品は吸収パッド12に綿からなった不織布12aと共に木材パルプウェブ12bが含まれているので、月経血を迅速に吸収して安全に保持することができる。
以上のように、本発明によれば、種々の女性疾患を効果的に予防することができ、着心地や肌触りに優れ、通気性にも優れており、月経血や尿などを迅速に吸収して安全に保持することができ、月経血や尿の漏れも効果的に遮断することができる。
