Description
【０００１】[0001]
この考案は、使い捨ておむつに関する。 This invention relates to disposable diapers.
【０００２】[0002]
従来、使い捨ておむつの脚周りからの体液漏れを防止するために、おむつの脚 周りにフラップを設ける技術がある。また、その防止効果を高めるために、フラ ップに吸液性コアを包容させる技術がある。この考案は、後者の技術を対象にし ている。 Conventionally, there is a technique of providing a flap around a leg of a diaper in order to prevent body fluid leakage from around the leg of a disposable diaper. In addition, there is a technique of enclosing a liquid-absorbent core in a flap in order to enhance its prevention effect. This invention addresses the latter technology.
【０００３】[0003]
従来技術で脚周りの漏れ防止効果を一層高めるには、吸液性コアの素材、例え ば粉砕パルプ、の使用量を増やし吸液量を高めればよい。しかし、これでは、フ ラップが分厚いものとなり、内股ではフラップとおむつ本体のそれぞれの吸液性 コアが狭い両脚の間（すなわち股下部位）を占めておむつがかさ張り、着用感を 著しく損ねるという問題が起きる。また、このフラップが邪魔になって本体の吸 液性コアが局部に密着せず、排出した体液を局部近傍で速やかに吸収することが 難しくなるという問題もある。 In order to further enhance the effect of preventing leakage around the leg in the prior art, the amount of liquid absorbent core material, for example, ground pulp, may be increased to increase the amount of liquid absorbed. However, in this case, the flap becomes thicker, and in the inner thigh, the absorbent cores of the flap and the diaper main body occupy the space between the narrow legs (that is, the inseam portion). Get up. There is also a problem that the flaps hinder the liquid-absorbing core of the main body from coming into close contact with the local portion, making it difficult to quickly absorb the discharged body fluid near the local portion.
【０００４】 そこで、この考案は、脚周りフラップに吸液拡散性などに優れた吸液性コアを 使用して、フラップが薄くても高い吸液性能を発揮できるようにし、前記問題を 解決することを課題にしてある。Therefore, the present invention solves the above-mentioned problem by using a liquid-absorbing core having excellent liquid-absorbing diffusibility for the flaps around the legs so as to exhibit high liquid-absorbing performance even when the flap is thin. That is the task.
【０００５】[0005]
この考案は、透液性表面シートと不透液性裏面シートとの間に吸液性の第１コ アが介在し、前記第１コアの各側縁から外側へ各第１フラップが延出していて該 各第１フラップにはその縦方向へ伸縮する各第１弾性部材が取付けられ、前記第 １コアの各側縁と前記各第１フラップの側縁との間には各第２フラップの基縁部 が位置していて該各第２フラップの自由縁部にその縦方向へ伸縮する各第２弾性 部材が取付けてある使い捨ておむつの改良にある。 In this invention, a liquid-absorbing first core is interposed between a liquid-permeable top sheet and a liquid-impermeable backsheet, and each first flap extends outward from each side edge of the first core. A first elastic member extending and contracting in the longitudinal direction is attached to each first flap, and a second flap is provided between each side edge of the first core and the side edge of each first flap. The present invention is an improvement in a disposable diaper in which a base edge portion is located and a second elastic member which expands and contracts in a longitudinal direction is attached to a free edge portion of each second flap.
【０００６】 改良に係るこの考案においては、前記各第２フラップは、透液性内面シートと 不透液性外面シートとの間に吸液性の第２コアが介在し、前記第２コアは、前記 第１コアよりも薄く、かつ、単位表面積当りの吸液量が高くされ、前記各第２フ ラップは、外側かつ前記各第１フラップ上に倒された状態で該各第２フラップの 縦方向両端部が固定され、前記両端部間の前記各第２フラップ部分が前記各第２ 弾性部材の収縮で上方へ起き上がる性向を有していることを特徴とする。In the invention according to the improvement, each of the second flaps has a liquid-absorbing second core interposed between a liquid-permeable inner sheet and a liquid-impermeable outer sheet, and the second core is The second flap is thinner than the first core and has a higher liquid absorption per unit surface area, and each of the second flaps is placed outside and on each of the first flaps. Both ends in the longitudinal direction are fixed, and each of the second flap portions between the both ends has a tendency to rise upward due to contraction of each of the second elastic members.

この考案に係る使い捨ておむつの詳細を添付の図に基づいて説明すると以下の とおりである。 The details of the disposable diaper according to the present invention are described below with reference to the attached drawings.
【０００８】 図１は、この考案に係る使い捨ておむつ１の平面図であって、一部が切り欠い てある。おむつ１では、透液性表面シート２、不透液性裏面シート３、およびこ れら両シート２，３間に吸液性の第１コア４を介在させ、脚周り側縁９と後身頃 の端縁１０とに伸縮性のゴム糸１１，１２を貼着し、後身頃の両側縁にはテープ ファスナ１３の一端が貼着してある。表面シート２の上面には第２フラップ７が 取付けてある。FIG. 1 is a plan view of a disposable diaper 1 according to the present invention, with a part cut away. In the diaper 1, a liquid-permeable top sheet 2, a liquid-impervious back sheet 3, and a liquid-absorbing first core 4 are interposed between these two sheets 2 and 3, and a leg peripheral side edge 9 and a back body. Elastic rubber threads 11 and 12 are adhered to the edge 10 and one end of a tape fastener 13 is adhered to both side edges of the rear body. A second flap 7 is attached to the upper surface of the topsheet 2.
【０００９】 図２は、図１におけるＩＩ−ＩＩ線断面図であるが、第２フラップ７について は、後記ゴム糸２３が収縮することにより表面シート２からやや浮き上がった状 態で示してある。表裏面シート２，３は第１コア４の側縁から延出して接着剤（ 図示せず）により互いに接合し、この延出部で第１フラップ１５が形成してある 。この第１フラップ１５において表面シート２上に設けた第２フラップ７は、お むつ１の内側に面した透液性内面シート１６と外側に面した不透液性外面シート １７との間に吸液性の第２コア２０を介在させ、両シート１６，１７間の側縁を 第２コア２０の両側でそれぞれ接着剤（図示せず）により接合することにより構 成してある。接合した一方の側縁２１は、第１コア４の側縁６に隣接して、ホッ トメルト接着剤２７により表面シート２に接合してある。他方の側縁２２には、 内外面シート１６，１７間に伸縮性のゴム糸２３を伸長下に貼着し、第２フラッ プ７に伸縮性を持たせるとともに、おむつ１を着用したときに図２のごとく表面 シート２から浮き上がるようにしてある。なお、第２フラップ７は、その端縁２ ５，２６において外側方向へ倒伏して斜線で示す部位を表面シート２に接合し、 この接合によりゴム糸２３の両端を表面シート２に固定してある（図１参照）。FIG. 2 is a cross-sectional view taken along the line II-II in FIG. 1. However, the second flap 7 is shown in a state where it is slightly lifted from the top sheet 2 due to contraction of a rubber thread 23 described later. The front and back sheets 2 and 3 extend from the side edge of the first core 4 and are joined to each other by an adhesive (not shown), and a first flap 15 is formed at the extending portion. The second flap 7 provided on the top sheet 2 in the first flap 15 absorbs a liquid between the liquid-permeable inner sheet 16 facing the inside of the diaper 1 and the liquid-impermeable outer sheet 17 facing the outside. A liquid second core 20 is interposed, and side edges between the sheets 16 and 17 are joined on both sides of the second core 20 with an adhesive (not shown). One of the joined side edges 21 is joined to the topsheet 2 by a hot melt adhesive 27 adjacent to the side edge 6 of the first core 4. On the other side edge 22, an elastic rubber thread 23 is adhered between the inner and outer sheets 16 and 17 under elongation so that the second flap 7 has elasticity and when the diaper 1 is worn. As shown in FIG. In addition, the 2nd flap 7 is joined to the topsheet 2 at the end edges 25 and 26, and the portion shown by oblique lines which falls down outward is joined to the topsheet 2, and both ends of the rubber thread 23 are fixed to the topsheet 2 by this joining. (See FIG. 1).
【００１０】 第２コア２０は、第２フラップ７において端縁２５，２６の近傍を除き、ほぼ その全長にわたり延在させてある。第２コア２０の厚みｔは、第１コア４の厚み Ｔより薄く、好ましくは厚みＴの１／４〜３／４にして着用時の障害にならない ようにしてあり、また、このコア２０は、単位表面積当りの吸液量が第１コア４ よりも高くしてある。The second core 20 extends over substantially the entire length of the second flap 7 except for near the edges 25 and 26. The thickness t of the second core 20 is smaller than the thickness T of the first core 4, preferably 1/4 to 3/4 of the thickness T so as not to hinder wearing. The liquid absorption amount per unit surface area is higher than that of the first core 4.
【００１１】 単位表面積当りの吸液量の高い第２コア２０は、高吸水性ポリマー３６と粉砕 パルプ３５との混合物、高吸水性ポリマー３６と粉砕パルプ３５とレーヨン繊維 などの繊維素材との混合物により得ることができる。吸液量は、主として高吸水 性ポリマー３６の混合量により調整し、好ましくは第１コア４の吸液量の１．１ 〜５．０倍にする。単位表面積当りの吸液量の高い第２コア２０であると、脚周 りで第１コア４の吸液量が飽和状態に達しても第２コア２０にまだ多くの吸液を 期待することができる。The second core 20 having a high liquid absorption amount per unit surface area includes a mixture of the superabsorbent polymer 36 and the ground pulp 35 and a mixture of the superabsorbent polymer 36 and the ground pulp 35 and a fiber material such as rayon fiber. Can be obtained by The liquid absorption amount is adjusted mainly by the mixing amount of the superabsorbent polymer 36, and is preferably set to 1.1 to 5.0 times the liquid absorption amount of the first core 4. If the second core 20 has a high liquid absorption amount per unit surface area, the second core 20 still expects a large amount of liquid absorption even when the liquid absorption amount of the first core 4 reaches a saturated state around the leg. Can be.
【００１２】 第２フラップ７は、図２のごとく第１コア４の側縁６に隣接し、Ｖ字溝２８を 形成するように取付けてある。体液が第１コア４に吸収されずおむつ幅方向へ流 れたときには、ここで一旦せき止められて停滞し、その間に第１コア４および第 ２コア２０へ吸収される。その結果、第２フラップ７を超えて流出しようとする 体液の量が減り、それだけ脚周りからの漏れの可能性が少なくなる。The second flap 7 is adjacent to the side edge 6 of the first core 4 as shown in FIG. 2, and is attached so as to form a V-shaped groove 28. When the bodily fluid flows in the diaper width direction without being absorbed by the first core 4, the bodily fluid is temporarily dammed and stagnates here, while being absorbed by the first core 4 and the second core 20. As a result, the amount of the bodily fluid that is going to flow out beyond the second flap 7 is reduced, and the possibility of leakage from around the leg is reduced accordingly.
【００１３】 おむつ１において、表裏面シート２，３は外周を密に接合してある。この接合 を含む、この実施例における接合には、ホットメルト接着剤などの接着剤や熱可 塑性合成樹脂素材を熱融着する技術を利用することができる。透液性の表面シー ト２と内面シート１６とには同一素材を使用することが可能であり、また両シー ト２，１６の親水性に差をつけることも可能であり、これらの素材には不織布や 開孔プラスチックシートが好適である。不透液性の裏面シート３と外面シート１ ７とに同一素材を使用することも可能であり、これにはプラスチックシートが好 適である。第１コア４には、粉砕パルプ、レーヨン繊維、熱可塑性合成繊維など の繊維素材を単独で、またはこの素材と高吸水性ポリマーとを混合し、必要に応 じて賦型して、使用することができる。In the diaper 1, the outer surfaces of the front and back sheets 2 and 3 are tightly joined on the outer periphery. In this embodiment including this joining, a technique of heat-sealing an adhesive such as a hot melt adhesive or a thermoplastic synthetic resin material can be used. The same material can be used for the liquid-permeable surface sheet 2 and the inner sheet 16, and the hydrophilicity of the sheets 2 and 16 can be differentiated. Is preferably a nonwoven fabric or a perforated plastic sheet. It is also possible to use the same material for the liquid-impermeable back sheet 3 and the outer sheet 17, and a plastic sheet is suitable for this. For the first core 4, a fibrous material such as ground pulp, rayon fiber, thermoplastic synthetic fiber, or the like is used alone, or a mixture of this material and a superabsorbent polymer is formed and used as needed. be able to.
【００１４】[0014]
この考案に係るおむつでは、第２フラップに、第１コアより薄くて、単位表面 積当りの吸液量が高い第２コアを設けたことにより、脚周りに流動した体液を速 やかに吸収、拡散して脚周りからの漏れを防止することができる。 In the diaper according to the present invention, the second flap is provided with the second core, which is thinner than the first core and has a high liquid absorption amount per unit surface area, so that the body fluid flowing around the leg can be quickly absorbed. It can be prevented from spreading and leaking from around the leg.
【００１５】 第２フラップを第１フラップ上に倒してあるから、おむつの着用状態では、第 １フラップがその第１弾性部材の収縮で第２フラップを着用者の肌に圧接させ、 その結果、前記漏れ防止が一層有効になる。[0015] Since the second flap is folded down on the first flap, when the diaper is worn, the first flap causes the second flap to press against the wearer's skin by the contraction of the first elastic member. The leak prevention is more effective.
