Description
この型の衛生製品の種々の変形が公知である。これらの製品はすべて後部の不透液性カバー層と、頂部の透液性カバー層とを備え、これらの2層の間に吸収体が挿入されている。
後部のカバー層は通常薄いポリエチレン膜から成る。頂部の透液性カバー層は多くの場合、不織布材料から成るが、パーフォレーション膜を使用することもできる。
原則として吸収体はセルローズ繊維又はいわゆるエアレイド材料から成る。
吸収体の基本的吸収能力のほか、接触に際しての柔らかさ、身体からの流体に対する吸収時間、衛生製品全体の分布及び再湿潤特性など、身体対向カバー層の技術的特徴が本質的である。身体対向カバー層として一般に使用される不織布カバーは前記の特徴の大部分に関して有効である。
前述のパーフォレーション膜はその吸収能力及び例えば月経液の導入後の視覚印象に関して改良されているが、蒸散作用(perspiration)を生じるパーフォレーション膜のプラスチック特性が問題となる。
身体対向層の吸収時間、身体からの流体の分布及び再湿潤に関する前述の特性は衛生ナプキン製品の漏れ安全性に関して大きな影響を与える。先行技術においては、これらの点に良好な影響を与える種々の手段が公知である。例えば、吸収時間と再湿潤特性とを改良するために身体対向カバー層の下に流体搬送層が挿入された。また身体からの流体の横方向漏れに対する安全性を増大する前記の衛生製品の長手方向液体分布に関する改良が衛生ナプキン表面上の長手方向プレス線によって得られた。
衛生製品の漏れ安全性に関する実質的な寄与がいわゆるカフス(cuffs)によって得られた。これらのカフスは吸収体の両側の横縁にそって配置された液体障壁を成し、この障壁は弾性材料によって直立状態に保持され身体からの流体の横方向漏れを防止する。これらのカフスは漏れ安全性を大幅に改善するが、これは衛生ナプキン、おむつ、失禁製品などの製造を著しく複雑にする。
前述の問題点を改良するため、本発明の目的は、表面の柔らかな自然な感触を保持すると共に、改良された着用快適性、身体からの流体の長手方向分布及び再湿潤特性を有し、また漏れ安全性を増大することができるように、公知の型の衛生製品を改良するにある。
この目的は請求項1に記載の特徴部分の特徴によって達成される。正面カバー層を請求項1のように波形とすることにより、「プリーツ」と呼ぶのが最も適当な面が得られる。
これらの波形は、長手方向液体分布の改良のために衛生製品表面に長手方向チャンネルを形成すると同時に、液体の横方向拡散に対する障壁を成す。これは衛生製品の漏れ安全性を著しく改良する。
さらにこれらの波形はカバー層表面の大部分において、波形それ自体と下方の吸収体との間に一定のスペースを備え、このスペースは吸収体の中への身体からの流体の吸収作用と再湿潤特性とを改良する。例えば月経液の導入後に、隆起した波形が月経液を浸漬された吸収体と接触しないので、衛生ナプキンの見た感じも良くなる。また波形の可撓性が衛生ナプキンの身体面の柔らかさに影響して、着用快適性を増進しまた自然の快適性と自然の触感とを与える。
波形の固着法の故にこれらの波形は安定であって、圧縮状態の貯蔵後にもまた長期間の着用後にもその良好な作用が失われない。
また、請求項1によれば、波形の脚区域は吸収体上に直接に接着又は溶着され、あるいはカバー層と吸収体との間に挿入された支持層上に固着される。この支持層は、波形の液体転送及び再湿潤特性に関する機能特徴をさらに改良するのに役立つ。
また、2つの隣接する波形(10)の脚区域(16)は、1mmから20mmの相互間隔(A)で固定されている。
また、波形(10)の高さ(H)は、無荷重状態において1mmから20mmである。
さらに、波形(10)は、吸収体(2)の区域の横方向の両側縁部及び中心の領域のみに形成されている。
以下、本発明を図面に示す実施例について詳細に説明するが本発明はこれに限定されない。
付図において、
第1図は本発明の参考例による衛生ナプキンの部分的斜視図、
第2図は第1図の衛生ナプキンの断面図及びその部分的拡大図、
第3図は本発明の参考例による衛生ナプキンの第2実施態様の断面図、
第4図は本発明の参考例による衛生ナプキンの第3実施態様の断面図、また
第5図は本発明による衛生ナプキンの第4実施態様の斜視図である。
付図に図示のように、それぞれの衛生ナプキンの相異なる実施態様はすべて主要部分において同型のベース構造を有する。衛生ナプキンの後側面3は不透液性カバー層、すなわち下着保護膜1を備え、この保護膜1は衛生ナプキンの後側面3において、すなわち着用時に身体を避ける衛生ナプキン側面において、セルローズ繊維パッドから成る吸収パッド2の下に配置される。さらに下着保護膜1の長手方向縁4が吸収パッド2の横縁5を覆う。
例えば不織布材料から成る支持層7が衛生ナプキンの正面区域6上に配置される。この支持層7の長手方向縁8も吸収パッド2の横縁5の上に配置されて、下着保護膜1の長手方向縁4の上に重なる。この重なり合い区域においてこれらの縁部分が通常のように相互に接着される。
支持層7の上に、透液性カバー層9が配置され、このカバー層9が後述のように波形10を有する。第1図、第2図及び第4図に図示の衛生ナプキンの実施態様はいわゆる「完全包装衛生ナプキン」であって、例えばプロピレンカードウエブから成り吸収パッド2と支持層7を包囲するカバー層9を備える。カバー層9は衛生ナプキン後側面3上に折り畳まれ、後側面3の中心において接着剤によって接着されている。
第3図と第5図の実施態様は側面ウィング12を備え、この側面ウィングは重ね合されたフラップ13、14から成り、上フラップ13は衛生ナプキンの前側においてカバー層9の横縁に接合され、下フラップ14は衛生ナプキンの後側においてカバー層15に接合されている。カバー層15は第3図の場合のように不織布材料から成り、別個の下着保護膜1を備えることができる。又はカバー層15が透液性材料、例えばポリエチレン膜から成り、下着保護膜の機能を引き受けて、下着保護膜1を省略することができる。
次に図示の衛生ナプキン中に使用される波形の種々の形状についてさらに詳細に説明する。
波形10は、衛生ナプキン製造機の中において、その脚区域16が衛生ナプキンの横方向に1mmから20mmの間隔をもって支持層7上に配置されるように適当な波形形成装置によって形成される。3mmから5mmの脚区域間隔が最も有効であることが発見された。脚区域16は支持層7に対して、長手方向接着剤ストリップ17、例えばスプレー接着剤によって接着される。各隣接脚区域16の間において、波形10は1mmから20mmの範囲内の高さHをもって直立する。この高さの最も有効な値は3mmから5mmの範囲内である。接着剤ストリップ17の幅によって決定される脚部幅Fは波形間隔Aと高さHとに対応して0.2mmから10mmの範囲内とすることができるが、最大脚幅Fは間隔Aの半分であることを考慮しなければならない。3mmから5mmの範囲内の間隔Aと高さHの場合、0.5mmから1mmの脚部幅が適当であることが発見された。
第1図乃至第3図の実施態様においては、吸収パッドの幅全体にそって8波形が均等間隔で備えられ、波形間隔Aは約6mmである。
第4図に図示の実施態様においては、両側の2本のストリップ18の中にそれぞれ2つの波形10が備えられ、これらの2波形10は衛生ナプキンの長手方向に延在しまた約6mmの間隔Aと高さHとを有する。衛生ナプキンの両側ストリップ18の間のストリップの中央部19は透液性カバー9から成り、このカバー9が支持層7の上側面に均一に配置され、この支持層7に対して中心接着剤ストリップ17’によって接着されている。また小量の透液性接着剤を使用して表面全体を接着することができる。
第5図に図示の衛生ナプキンの実施態様は、両側の接着剤ストリップ18上の波形10のほか、中心面Lに対して対称的な3波形10から成る波形構造を備え、この中心波形10と両側波形10との間に、波形を有しないストリップ部分20が残存する。
第2図乃至第4図の断面から明かなように、波形10の頂部、中間凹部21、及び接着された脚区域16の間において波形10の下方にある管部22が衛生ナプキン中に導入された身体からの流体の長手方向分布のためのチャンネルを成す。
最後に、本発明の衛生ナプキンの各部品は、このような衛生ナプキンの製造のための通常の基準に従って市販されている適当材料とすることができる。例えば、衛生ナプキンの吸収面が相当多量に残存する程度に接着剤ストリップ17が液体の進入を制限するように、これらの接着剤ストリップ17を支持層7の上に接着することが望ましい。スプレー接着剤又はメルトブローン接着剤の細い線を使用することができるが、他の可能性はレーザ、超音波又は熱による溶着又は密着である。
