Description

本発明は、使い捨ておむつ、生理用ナプキン、失禁パッド等の吸収性物品に関する。   The present invention relates to absorbent articles such as disposable diapers, sanitary napkins, and incontinence pads.

従来、使い捨ておむつ、生理用ナプキン、失禁パッド等の吸収性物品の表面シートとして、着用者の肌側に向けられる肌側面に、エンボス加工等により凹凸形状を形成したものが知られている。また、表面シートの肌側面に凹凸形状を形成することで、着用者の肌との接触面積を低減して、通気性を向上させたり、肌へのべたつきを低減したりする技術も知られている。   Conventionally, as a surface sheet of an absorbent article such as a disposable diaper, a sanitary napkin, an incontinence pad, etc., an uneven surface formed by embossing or the like is known on the skin side face directed to the skin side of the wearer. In addition, by forming an uneven shape on the skin side of the topsheet, it is also known to reduce the contact area with the skin of the wearer to improve air permeability and reduce stickiness to the skin. Yes.

通気性を向上させたり肌のべたつきを低減する観点からは、表面シートの凹凸形状は、その保形性が高いことが好ましい。しかし、一般に、保形性を高めようとすると風合い（肌触り）が悪化したり、表面シートの表面から吸収体側への液の引き込み性が低下したりする。   From the viewpoint of improving the air permeability and reducing the stickiness of the skin, it is preferable that the concavo-convex shape of the surface sheet has a high shape retaining property. However, generally, when trying to improve the shape retention, the texture (feel) is deteriorated, or the drawability of the liquid from the surface of the surface sheet to the absorber side is lowered.

特許文献１及び２には、使い捨ておむつの表面シートに、凸部の形状や高さが異なる複数の凹凸領域を設けることが記載されている。   Patent Documents 1 and 2 describe providing a plurality of concavo-convex regions with different shapes and heights of convex portions on a top sheet of a disposable diaper.

ところで、使い捨ておむつ等の吸収性物品は、フィット性や液漏れ防止の観点から、着用時に、着用者の股間に配される股下部の両側部が左右の大腿部に沿うように変形することが望まれる。しかし、前述のように、表面シートに形成した凹凸領域の剛性が高いと、着用者に脚回りに違和感を与えやすくなる。他方、表面シートに形成した凹凸領域の剛性を低いと、凹凸領域に形成した凹凸形状の保形性が低下する。   By the way, an absorbent article such as a disposable diaper is deformed so that both sides of the crotch part arranged between the crotch of the wearer are along the left and right thighs at the time of wearing from the viewpoint of fit and prevention of liquid leakage. Is desired. However, as described above, when the unevenness area formed on the topsheet has high rigidity, it is easy for the wearer to feel uncomfortable around the legs. On the other hand, if the rigidity of the concavo-convex area formed on the top sheet is low, the shape retention of the concavo-convex shape formed in the concavo-convex area is lowered.

The first sheet and the second sheet that are stacked are joined to each other at a plurality of joints, and the first sheet is separated from the second sheet at a portion other than the joints. Projecting toward the wearer's skin side, the composite sheet is located on both sides of the central region and the central region where the convex portions are formed in different patterns A synthetic resin constituting one or both of the constituent fibers of the first sheet and the second sheet is melted and solidified at the joint portion in the side area. And has a state, all or part of the joint portions in the side region has a through-hole, there is provided an absorbent article.

本発明の吸収性物品は、着用者の脚回りに違和感を与えにくい上に、表面シートの凸部の保形性に優れており、通気性やムレ防止性に優れている。   The absorbent article of the present invention hardly gives an uncomfortable feeling to the wearer's legs, is excellent in the shape retention of the convex portion of the surface sheet, and is excellent in air permeability and stuffiness prevention.

第１実施形態における複合シート１０のサイド領域Ｓは、図１０に示すように、前述した第１方向接合部列Ｒｘと前述した第２方向接合部列Ｒｙのうちの、第２方向接合部列Ｒｙが、貫通孔３３ｃを有する接合部３３ａの割合が最も高い最大割合接合部列Ｒｙｍを含んでいる。
第２方向接合部列Ｒｙが最大割合接合部列Ｒｙｍを含むことで、おむつ１００の幅方向（物品幅方向）に沿って折れ曲がり易く、おむつ１００の着用時に、複合シート１０のサイド領域Ｓが配されたおむつ１００の両側部部分が、着用者の脚回りの湾曲形状に沿って曲がり易く脚回りへのフィット感が向上し、着用者の脚回りに違和感を与えにくい。 As shown in FIG. 10, the side region S of the composite sheet 10 in the first embodiment is a second direction joint portion row of the first direction joint portion row Rx and the second direction joint portion row Ry described above. Ry includes the maximum proportion joint row Rym in which the proportion of the joint portion 33a having the through hole 33c is the highest.
When the second direction joint portion row Ry includes the maximum proportion joint portion row Rym, the side region S of the composite sheet 10 is arranged easily when the diaper 100 is worn because the diaper 100 is easily bent along the width direction (the article width direction). The both side portions of the formed diaper 100 are easy to bend along the curved shape of the wearer's leg, and the fit to the leg is improved, so that the wearer's leg is less likely to be uncomfortable.

ここで、「最大割合接合部列」は、おむつ１枚の各サイド領域Ｓから任意に２枚ずつ切り出した第１方向の長さ２０ｍｍ、第２方向の長さ１００ｍｍ矩形状の測定片を観察して、以下の手順（１）〜（３）で決定する。
（１）第１方向接合部列Ｒｘのなかから、貫通孔３３ｃを有する接合部３３ａの割合が最も高い接合部列を選択して、その接合部列を第１方向最大割合接合部列Ｒｘｍとする。例えば、図１０に示すように、第１方向接合部列Ｒｘとして、貫通孔を有しない第３接合部３３と貫通孔３３ｃを有する第３接合部３３ａとを第１方向Ｘに交互に有し、その接合部列を構成する接合部の個数のうちの貫通孔３３ｃを有する接合部３３ａの割合（以下、「孔付接合部割合」ともいう）が５０％である第１方向第１接合部列Ｒｘ１と、その接合部列を構成する接合部の個数のうちの全てが貫通孔３３ｃを有しない接合部３３であって、前記孔付接合部割合が０％である第１方向第２接合部列Ｒｘ２とを有する場合、前記孔付接合部割合が最も高い第１方向第１接合部列Ｒｘ１が、第１方向最大割合接合部列Ｒｘｍとなる。
（２）第２方向接合部列Ｒｙのなかから、貫通孔３３ｃを有する接合部３３ａの割合が最も高い接合部列を選択して、その接合部列を第２方向最大割合接合部列Ｒｙｍとする。例えば、図１０に示すように、第２方向接合部列Ｒｙとして、接合部列を構成する接合部の個数のうちの全てが貫通孔３３ｃを有する接合部３３ａであり、孔付接合部割合が１００％である第１の第２方向第１接合部列Ｒy１と、接合部列を構成する接合部の個数のうちの全てが貫通孔３３ｃを有しない接合部３３であり、前記孔付接合部割合が０％である、第２の第２方向第１接合部列Ｒｙ１及び第２方向第２接合部列Ｒｙ２とを有する場合、前記孔付接合部割合が最も高い第１の第２方向第１接合部列Ｒｙ１が、第２方向最大割合接合部列Ｒｙｍとなる。図１０に示す例においては、第１方向Ｘに３列置きに配された第１の第２方向第１接合部列Ｒｙ１が、第２方向最大割合接合部列Ｒｙｍである。
（３）第１方向最大割合接合部列Ｒｘｍの孔付接合部割合と、第２方向最大割合接合部列Ｒｙｍの孔付接合部割合とを比較し、孔付接合部割合がより高い方を、最大割合接合部列とする。図１０に示す例では、第１方向最大割合接合部列Ｒｘｍの孔付接合部割合が５０％であるのに対し、第２方向最大割合接合部列Ｒｙｍの孔付接合部割合が１００％であるため、孔付接合部割合が１００％である、第２方向最大割合接合部列Ｒｙｍが最大割合接合部列となる。 Here, the “maximum proportion joint line” is an observation of a rectangular measuring piece having a length of 20 mm in the first direction and a length of 100 mm in the second direction, which is arbitrarily cut out from each side region S of one diaper.

For example, as shown in FIG. 10, as the first direction joint line Rx, the third joint 33 having no through hole and the third joint 33a having the through hole 33c are alternately arranged in the first direction X. The first direction first joint portion in which the proportion of joint portions 33a having through holes 33c out of the number of joint portions constituting the joint portion row (hereinafter, also referred to as “perforated joint portion ratio”) is 50%. The first direction second joint in which the row Rx1 and the number of joint portions constituting the joint row are all joint portions 33 having no through-holes 33c, and the joint portion ratio with holes is 0%. In the case of having the partial row Rx2, the first direction first joint row Rx1 having the highest hole-attached portion ratio becomes the first direction maximum proportion joint portion row Rxm.
(2) From the second direction joint line Ry, select the joint line having the highest ratio of the joints 33a having the through holes 33c, and select the joint line as the second direction maximum rate joint line Rym.

For example, as shown in FIG. 10, as the second direction joint portion row Ry, all of the number of joint portions constituting the joint portion row are joint portions 33a having through holes 33c, and the joint portion ratio with holes is 100% of the first second-direction first joint rows Ry1 and the number of joints constituting the joint rows are joint portions 33 that do not have through holes 33c, and the joint portions with holes When the second second-direction first joint row Ry1 and the second-direction second joint row Ry2 have a ratio of 0%, the first second-direction first in the hole-attached joint portion is the highest. One junction row Ry1 is the second direction maximum proportion junction row Rym. In the example shown in FIG. 10, the first second direction first joint rows Ry1 arranged in every third row in the first direction X are the second direction maximum proportion joint rows Rym.

第１実施形態における複合シート１０のサイド領域Ｓの構成について更に説明する。
図３、図５及び図１０に示されるとおり、複合シート１０のサイド領域Ｓには、サイド第１凸部４１’が、複合シート１０に、平面視散点状、より詳細には千鳥状に形成されている。サイド第１凸部４１’は、前述した６個の第３接合部３３によって囲まれている。サイド第１凸部４１’を囲む６個の第３接合部３３及び６個の第３接合部３３における互いに隣り合う第３接合部３３間の部位は、サイド第１凸部４１’の中央部の周囲に環状の凹部を形成しており、サイド第１凸部４１’は、複合シート１０の平面方向に分散した状態に形成されている。
より詳細には、図１０に示すように、平面視した複合シート１０に、互いに平行な複数本の第１の仮想直線Ｌ３と、第１仮想直線Ｌ３との間に角度θ（図１０参照）を有する互いに平行な複数本の第２の仮想直線Ｌ４とを想定したときに、第１仮想直線Ｌ３と第２仮想直線Ｌ４との各交点に、サイド第１凸部４１’が位置している。
サイド第１凸部４１’を格子の交点に配置することで、股下部Ｃ等における中央領域Ｍ上に供給された液体は、第２方向Ｙに沿って配置された溝部５が導液路になってサイド領域Ｓに導かれ、サイド領域Ｓに格子状に配置されたサイド第１凸部４１’が障壁となり第１方向Ｘへの拡散も促進し、尿等の排泄物の吸収体１４の全域からの均一吸収をさらに促進することができる。

Assuming a plurality of second virtual straight lines L4 that are parallel to each other, the side first convex portion 41 ′ is located at each intersection of the first virtual straight line L3 and the second virtual straight line L4. .
By disposing the side first convex portion 41 ′ at the intersection of the lattice, the liquid supplied onto the central region M in the crotch portion C or the like has the groove portion 5 disposed along the second direction Y in the liquid introduction path. The side first convex portions 41 ′ guided to the side region S and arranged in a lattice pattern in the side region S serve as a barrier to promote diffusion in the first direction X, and the absorption body 14 for excrement such as urine Uniform absorption from the entire area can be further promoted.

そのため、第３方向凸部列どうし間及び第４方向凸部列どうし間は、空気が流通し易い通気路となり、優れた通気性が得られる。 In the side region S of the composite sheet 10, a plurality of side first convex portions 41 ′ are arranged at regular intervals along a plurality of third direction convex portion rows in series along the first imaginary straight line L 3. The side first convex portions 41 ′ are formed with a plurality of fourth direction convex portion rows arranged in series along the second virtual straight line L4 at a constant interval. In addition, a third direction joint row R5 in which a plurality of joint pairs 34 are arranged in series at a constant interval is formed between adjacent third direction convex rows, and between adjacent fourth direction convex rows. A fourth direction joint row R6 in which a plurality of joint pairs 34 are arranged in series at a constant interval is formed. Between the pair of third joints constituting each joint pair 34 and between the pair of adjacent joints 34 around the side first convex part 41 ′, there are minute convex parts 44 ′. The convex portion 44 ′ has a height that slightly protrudes from the upper surface of the third joint portion 33, and usually the height H4 ′ is 1/3 or less of the side first convex portion 41 ′.
Therefore, an air passage through which air easily flows is provided between the third direction convex row and between the fourth direction convex rows, and excellent air permeability is obtained.
