Description
このおむつにおいて、本発明が特徴とするところは、以下のとおりである。前記股下部材は、前記前端部と前記後端部との間に延びる長さ方向と、前記長さ方向に直交する幅方向とを有し、前記吸収体が少なくとも粉砕パルプと高吸水性ポリマー粒子とを含む吸水性材料の集合体である芯材を透水性のラッピングシートで被覆することにより形成されている。前記集合体は、前記胴回り被覆部材の前記内面と向かい合う外面の全体が前記ラッピングシートに接される一方、前記外面の反対面である前記集合体の内面は前記ラッピングシートに対する接合域と非接合域とを有し、前記接合域は前記集合体における前記幅方向の中央部分において前記長さ方向へ延びており、前記非接合域は、前記幅方向において前記接合域の両側に位置しており、前記ラッピングシートは、前記集合体の前記外面を被覆している前記ラッピングシートが前記集合体から前記幅方向へ延出する部分を折り返すことによって前記集合体の前記内面を被覆しているものであって、前記内面における前記中央部分において、折り返した前記ラッピングシートどうしが重なり合い、互いに接合されている。 The features of the present invention in this diaper are as follows. The crotch member has a length direction extending between the front end portion and the rear end portion, and a width direction orthogonal to the length direction, and the absorber is at least pulverized pulp and superabsorbent polymer particles. Is formed by covering a core material, which is an aggregate of water-absorbing materials, with a water-permeable wrapping sheet. The aggregate, whereas whole outer surface facing said inner surface of said waist covering member is against the wrapping sheet, the inner surface of the opposite surface a is the aggregation of the outer surface bonding region and a non-bonding region to said wrapping sheet And the joining area extends in the length direction at a central portion of the aggregate in the width direction, and the non-joining area is located on both sides of the joining area in the width direction , The wrapping sheet covers the inner surface of the assembly by folding back a portion of the wrapping sheet that covers the outer surface of the assembly that extends in the width direction from the assembly. The folded wrapping sheets are overlapped and joined to each other at the central portion of the inner surface .
図８，９は、実施態様の一例を示す体液吸収部３１の部分破断平面図と、その平面図におけるＩＸ−ＩＸ線断面図である。図示例の体液吸収部３１には、芯材４１とラッピングシート４２とに対して複数の条溝６１が形成されていて、その条溝６１がカバーシート４５によって覆われている。条溝６１は、芯材４１とラッピングシート４２とが芯材４１の内面４１ａから外面４１ｂへ向かう方向へ局部的に圧搾されることで形成されている。条溝６１の底部６１ａでは粉砕パルプ等の吸水性材料が圧縮された状態にあり、底部６１ａにおける芯材４１の密度は条溝６１の周辺域における芯材４１の密度よりも高くなっている。好ましい条溝６１は、ホットメルト接着剤ＨＡを介して芯材４１とラッピングシート４２とが接合している部位において、中心線Ｐに関して対称となるように形成される。また、条溝６１は、胴回り被覆部材１における前胴回り部３と後胴回り部４との間の股下部５において形成されることが好ましい。さらにはまた、条溝６１が一対だけ形成される場合には、その条溝は股下部５の前方部分に形成されていることが好ましい。おむつ１０が男性用のものである場合において、股下部５の前方部分に形成される一対の条溝６１は、それらの間に男性器が納まるようにおむつ１０が着用されると、股下部材２が身体によくフィットして、おむつ１０が着用感のよいものになる。体液吸収部３１におけるカバーシート４５は、粉砕パルプや高吸水性ポリマー粒子等の吸水性材料がラッピングシート４２やラッピングシート４２の破れ目から漏れ出して肌に接触するという問題の発生を防ぐことができる。 8 and 9 are a partially broken plan view of the bodily fluid absorbing portion 31 showing an example of the embodiment, and a cross-sectional view taken along the line IX-IX in the plan view. In the illustrated body fluid absorbing portion 31, a plurality of grooves 61 are formed in the core material 41 and the wrapping sheet 42, and the grooves 61 are covered with the cover sheet 45. The groove 61 is formed by locally squeezing the core material 41 and the wrapping sheet 42 in a direction from the inner surface 41a of the core material 41 toward the outer surface 41b. In a state where the water-absorbing material is compressed such bottom 61a in pulverized pulp grooves 61 is higher than the density of the core material 41 in the peripheral region of the density groove 61 of the core 41 at the bottom 61a. A preferable groove 61 is formed so as to be symmetric with respect to the center line P at a portion where the core material 41 and the wrapping sheet 42 are joined via the hot melt adhesive HA. The groove 61 is preferably formed in the crotch portion 5 between the front waistline portion 3 and the rear waistline portion 4 of the waistline covering member 1. Furthermore, when only one pair of groove 61 is formed, it is preferable that the groove is formed in the front part of the crotch part 5. When the diaper 10 is for men, the pair of grooves 61 formed in the front part of the crotch part 5 is the crotch member 2 when the diaper 10 is worn so that the male genital can be accommodated between them. Fits well to the body, and the diaper 10 is comfortable to wear. The cover sheet 45 in the body fluid absorbing portion 31 can prevent the occurrence of a problem that water-absorbing materials such as pulverized pulp and highly water-absorbing polymer particles leak from the ruptures of the wrapping sheet 42 and the wrapping sheet 42 and come into contact with the skin. .
