【発明の実施の形態】 DETAILED DESCRIPTION OF THE INVENTION
本発明のパンツ型吸収性物品を、その好ましい実施形態について説明する。 The pant-type absorbent article of the present invention will be described preferred embodiments thereof. パンツ型吸収性物品10は、図1〜3に示すように、着用時における内側に位置する液透過性のトップシート11と、着用時における外側に位置する液不透過性のバックシート12と、両シート11,12間において着用時における股下部相当位置に配設される実質的に縦長の液体保持性の吸収体13とからなり、ウエスト部14にはウエストギャザーを形成するウエスト弾性部材17が、レッグ部にはレッグギャザーを形成するレッグ弾性部材18が各々配設されている。 Pant-type absorbent article 10, as shown in FIGS. 1-3, a liquid-permeable topsheet 11 positioned on the inner side at the time of wearing, a liquid impermeable back sheet 12 located on the outside at the time of wearing, essentially consists elongated liquid retentive absorbent body 13 which is arranged in the crotch portion corresponding position when worn in between the two sheets 11 and 12, the waist portion 14 waist elastic member 17 forming the waist gather , leg elastic members 18 to form the leg gathers are respectively provided on the leg portion.
【0008】 [0008]
また、本実施形態によれば、吸収体13の臀部相当位置におけるバックシート12側すなわち外面側には、長手方向に延長する二本の縦溝20が形成されており、また、この縦溝20と交差するようにして、上記各弾性部材17,18とは異なる5本の弾性部材16が、バックシート側において横方向に延長配設されている。 Further, according to this embodiment, the back sheet 12 side, that is the outer surface side of the hip corresponding position of the absorbent body 13, longitudinal grooves 20 of the two extending longitudinally are formed, also, the longitudinal grooves 20 so as to intersect with the elastic member 16 of five different from said respective elastic members 17 and 18 are extended arranged laterally in the back sheet side.
【0009】 [0009]
液透過性のトップシート11や液不透過性のバックシート12は、従来のパンツ型の使い捨ておむつに使用されていたものと同様のもので、これらの間に、熱溶着やホットメルト剤等を介して、縦長の吸収体13を、着用時における股下部相当位置に固着する。 Liquid-permeable top sheet 11 and a liquid impervious backsheet 12 of the similar to those that were used in the conventional pants-type disposable diaper, between them, a heat welding or hot-melt adhesive or the like through it, the absorbent body 13 of elongated, stick to the crotch portion corresponding position when worn. またトップシート11とバックシート12は、その周縁部分を熱溶着などにより接合して一体化されている。 The topsheet 11 and the backsheet 12 is the peripheral portion are integrated by joining by thermal welding.
【0010】 [0010]
また、吸収体13は、生理用ナプキン、失禁用パッド、おむつ等に採用される、フラッフパルプ、吸収紙、高吸収性ポリマー等の、従来より吸収体を構成する材料として公知のものを特に制限なく用いて形成することができ、これを必要に応じて液透過性の表面シートや液不透過性の裏面シートで覆って使用する。 Furthermore, the absorbent body 13, a sanitary napkin, incontinence pad, is employed in a diaper or the like, fluff pulp, absorbent paper, such as superabsorbent polymers, particularly those known as the material constituting the absorber conventionally limited It can be formed by using not, covered by a liquid-permeable topsheet and a liquid impermeable backsheet for use as needed this. この実施形態によれば、吸収体13の縦長帯状の中央部分には、その周囲の部分より坪量が実質的に高くなった隆起部13aが形成されていて、装着時において、股下部のうち特に臀部におけるさらに良好な密着感が得られるようになっている。 According to this embodiment, the central portion of the elongated strip-shaped absorbent body 13, the basis weight than the surrounding parts have been substantially raised ridges 13a are formed, at the time of mounting, of the crotch portion especially better adhesion feeling in the buttocks is adapted to obtain.
【0011】 [0011]
吸収体13は、2.5g/cm 2荷重下における隆起部13aの厚みが7mmで、これら周囲の部分の厚みが4mmとなっており、その差が3mmとなっている。 Absorber 13, in 7mm thickness of the raised portion 13a under 2.5 g / cm 2 load, the thickness of the surrounding portion has a 4 mm, which is the difference between 3 mm. なお、隆起部13aの厚みは3〜15mmであることが好ましく、5〜12mmであることがより好ましい。 Incidentally, it is preferable that the thickness of the raised portion 13a is 3 to 15 mm, more preferably 5-12 mm. また、隆起部13aの周囲の厚みは1〜10mmであることが好ましく、2〜7mmであることがより好ましい。 Also, around the thickness of the raised portion 13a is preferably from 1 to 10 mm, more preferably 2 to 7 mm. さらに、これらの厚みの差は、2〜10mmであることが好ましく、2〜7mmであることがより好ましい。 Moreover, the difference between these thicknesses is preferably 2 to 10 mm, more preferably 2 to 7 mm.
【0012】 [0012]
吸収体13の臀部相当位置におけるバックシート12側に形成される二本の縦溝20は、エンボス加工、熱プレス加工等によって形成され、吸収体13の長手方向中心線と平行な方向からやや傾いて当該長手方向に直線状に延長し、 臀部相当位置においてパンツ型吸収性物品10のバックシート12側に延長配設された上記弾性部材16と交差すると共に、その端部が吸収体13の長手方向の一端縁部に至っている。 Two longitudinal grooves 20 formed in the back sheet 12 side in the hip corresponding position of the absorbent body 13, embossed, formed by hot pressing or the like, slightly inclined from the longitudinal center line parallel to the direction of the absorber 13 extending linearly in the longitudinal direction Te, with crossing the elastic member 16 which extends disposed in the back sheet 12 side of the pant-type absorbent article 10 in the hip corresponding position, the end of the absorbent body 13 longitudinally It has led to one end edge of direction. なお、縦溝20の深さは、十分な可撓性を得るためには吸収体13の厚みの20%以上が好ましく、40〜60%が一層好ましい。 The depth of the longitudinal groove 20 is preferably at least 20% of the thickness of the absorbent body 13 in order to obtain sufficient flexibility, even more preferably 40% to 60%. 溝の幅は、1mm以上が好ましく、2〜5mmが一層好ましい。 The width of the groove is preferably at least 1 mm, 2 to 5 mm is more preferred. 溝の長さは、吸収体の全体長の20%以上が好ましく、40〜60%が一層好ましい。 The length of the groove, the whole length of preferably 20% or more of the absorber, is more preferred 40% to 60%.
