Description

本発明は生理用ナプキンに関するものであり、より詳細には、生理用ナプキン着用者の動きによって、パンティーに付着された下部カバー層１０が人体から遠く離れても、下部カバー層１０と分離されている吸収パッド層２０の両側辺部が人体に密着された状態を維持すると共に、着用者の股部分にもしっかり密着され、月経血の漏れを効果的に遮断することができる生理用ナプキンに関するものである。 The present invention relates to a sanitary napkin, and more specifically, due to the movement of the sanitary napkin wearer, the lower cover layer 10 attached to the panties is separated from the lower cover layer 10 even if it is far away from the human body. A sanitary napkin that keeps both sides of the absorbent pad layer 20 in close contact with the human body and also firmly adheres to the wearer's crotch to effectively block the leakage of menstrual blood. Is.

月経血などを吸収することができる従来の生理用ナプキンとして、図１及び図２に示すように、（ｉ）フィルム素材の下部カバー層１０；（ｉｉ）前記下部カバー層１０の長さ方向に沿って下部カバー層１０の中央部に接着された吸収パッド層２０；及び（ｉｉｉ）前記吸収パッド層２０と下部カバー層１０とを覆っている上部カバー層３０を含む生理用ナプキンが主に使用されてきた。 As a conventional sanitary napkin capable of absorbing menstrual blood and the like, as shown in FIGS. 1 and 2, (i) the lower cover layer 10 of the film material; (ii) in the length direction of the lower cover layer 10. A sanitary napkin including an absorption pad layer 20 adhered to the central portion of the lower cover layer 10 along the same; and (iii) an upper cover layer 30 covering the absorption pad layer 20 and the lower cover layer 10 is mainly used. It has been.

前記吸収パッド層２０は、不織布素材や綿状パルプ素材などで製造され、前記上部カバー層３０は、不織布素材やメッシュフィルム素材などで製造される。 The absorbent pad layer 20 is made of a non-woven fabric material, a cotton-like pulp material, or the like, and the upper cover layer 30 is made of a non-woven fabric material, a mesh film material, or the like.

前記従来の生理用ナプキンは、特許文献１及び特許文献２等に掲載されている。 The conventional sanitary napkin is published in Patent Document 1 and Patent Document 2 and the like.

しかしながら、前記従来の生理用ナプキンの場合、吸収パッド層２０の下部全体の面積は下部カバー層１０に一体に接着されており、上部カバー層３０の下部全体の面積は吸収パッド層２０と下部カバー層１０に一体に接着されている。そのため、吸収パッド層２０と上部カバー層３０は下部カバー層１０と分離されず、一体に一緒に動かなければならなかった。そのため、生理用ナプキン着用者の動きによって、パンティーに接着された生理用ナプキンの下部カバー層１０が人体から離れると、吸収パッド層２０と上部カバー層３０も自然に人体から離れながら、人体に密着されず、着用者の股部分にもしっかり密着されず、月経血の漏れが生じる問題が発生する。 However, in the case of the conventional sanitary napkin, the entire area of the lower part of the absorption pad layer 20 is integrally adhered to the lower cover layer 10, and the entire area of the lower part of the upper cover layer 30 is the absorption pad layer 20 and the lower cover. It is integrally adhered to the layer 10. Therefore, the absorption pad layer 20 and the upper cover layer 30 were not separated from the lower cover layer 10, and had to move together. Therefore, when the lower cover layer 10 of the sanitary napkin adhered to the panties separates from the human body due to the movement of the sanitary napkin wearer, the absorption pad layer 20 and the upper cover layer 30 also naturally separate from the human body and adhere to the human body. It does not adhere firmly to the wearer's crotch part, and there is a problem that menstrual blood leaks.
