Description
本発明によれば、吸収性物品は、液体透過性トップシートを含み得る。本明細書に用いるのに好適なトップシートは、織布、不織布、及び/又は液体透過性開口を有する液体不透過性高分子フィルムの三次元ウェブを含み得る。図1において、トップシートは、参照番号30で示されている。例えば、着用者に面する表面から吸収性構造体に向かう液体の移送を促進するために提供された開口を有するフィルム材によって、着用者に面し、接触する表面を提供することができる。かかる液体透過性の有孔フィルムは、当該技術分野において周知である。それらは、弾性的な三次元繊維様構造体を提供する。このようなフィルムは、例えば、米国特許第3929135号、米国特許第4151240号、米国特許第4319868号、米国特許第4324426号、米国特許第4343314号、米国特許第4591523号、米国特許第4609518号、米国特許第4629643号、米国特許第4695422号、又はPCT国際公開特許WO96/00548号に詳細に開示されている。
本発明により、及び例えば図2及び図4の実施形態に示されるように、吸収性コア28は、基材層100、吸収性ポリマー材料110、熱可塑性材料の層120、典型的には例えば繊維化されたホットメルト接着剤の層120、及びカバー層130を備える。基材層100及びカバー層130は、以下で詳細に説明されるように、典型的には繊維性材料から得ることができる。
本発明によるコアを含む吸収性物品は、バックシート40を含むこともできる。バックシートは主に、吸収性構造に吸収され及び収容されている滲出物が、パンツ、ズボン、パジャマ、下着、及びシャツ又はジャケットなどの吸収性物品と接触する材料を濡らすことを防ぎ、これにより、流体移動に対するバリアとして作用しなければならない。本発明の実施形態によるバックシートは、少なくとも水蒸気の、又は水蒸気と空気の両方を通過させることもでき、したがって、物品内に空気を、物品外に水蒸気を循環させることができる。バックシートは、典型的には、吸収性構造全体にわたって延びていることが可能であり、サイドフラップ、サイドラッピング要素又はウィングが存在するならば、それらの一部に又は全体の中まで延びていることができる。
人工月経流体(Artificial Menstrual Fluid)は、ヒツジの変性血液を基本にしており、これは、粘度、導電性、表面張力、及び外観の点でヒトの月経液に確実に酷似するように、変性されたものである。それは、参照される米国特許第6,417,424号(プロクター・アンド・ギャンブル社(The Procter & Gamble Company)に譲渡)の第17段33行から第18段45行に説明されるとおりに調製される。
