The absorbent article may be any absorbent article such as a sanitary pad (discrete sheet), a sanitary napkin, an incontinence pad, or the like. The following embodiment is described as a disposable sanitary napkin as an example of an absorbent article.

此外，在以下圖面的記載中，在同一或近似的部分標示同一或近似的符號。可是，圖面為模式者，必須留意各尺寸的比率等與現實者不同的情況。因此，具體的尺寸等必須參酌以下的說明進行判斷。又，即使在圖面相互間也可能包含有互相的尺寸的關係、比率不同的部分。 In addition, in the description of the following drawings, the same or similar symbols are denoted by the same or similar parts. However, if the drawing is a pattern, it is necessary to pay attention to the case where the ratio of each size is different from the actual one. Therefore, the specific dimensions and the like must be judged by referring to the following description. Further, even if the drawings face each other, they may include portions having different dimensional relationships and ratios.

(1)吸收性物品的整體構造 (1) The overall structure of the absorbent article

圖1是一實施形態中的吸收性物品的俯視圖。圖2是與圖1從相反側看的吸收性物品的俯視圖。圖3是沿著圖1的3A-3A線的吸收性物品的剖視圖。 Fig. 1 is a plan view of an absorbent article according to an embodiment. Fig. 2 is a plan view of the absorbent article as seen from the opposite side of Fig. 1. Fig. 3 is a cross-sectional view of the absorbent article taken along line 3A-3A of Fig. 1.

吸收性物品1具有：前後方向L與寬邊方向W和厚度方向T。前後方向L，是從裝用者的前側(腹側)朝後側(背測)延伸的方向，或從裝用者的後側朝前側延伸的方向。寬邊方向W，是與前後方向L正交的方向。厚度方向T，是從裝用者的肌膚面側T1朝非肌膚面側T2延伸的方向且是和前後方向L及寬邊方向W正交的方向。肌 膚面側T1在使用時相當於面向裝用者的肌膚之側。非肌膚面側T2在使用時相當於與肌膚面側T1相反側，亦即相當於面向與裝用者的肌膚的相反之側。 The absorbent article 1 has a front-rear direction L, a widthwise direction W, and a thickness direction T. The front-rear direction L is a direction extending from the front side (ventral side) of the wearer toward the rear side (back measurement) or a direction extending from the rear side of the wearer toward the front side. The widthwise direction W is a direction orthogonal to the front-rear direction L. The thickness direction T is a direction extending from the skin surface side T1 of the wearer toward the non-skin surface side T2 and is a direction orthogonal to the front-rear direction L and the widthwise direction W. muscle The skin side T1 is equivalent to the side facing the wearer's skin when in use. The non-skin side T2 corresponds to the side opposite to the skin side T1 when it is used, that is, the side opposite to the skin of the wearer.

吸收性物品1具有：***口抵接域S1、前側域S2及後側域S3。***口抵接域S1，是和裝用者的***口(例如***口)對置的區域。***口抵接域S1，是將吸收性物品安裝在內褲時，位在內褲的***部。亦即，***口抵接域，是被配置在裝用者的***，亦即被配置在裝用者的兩腿之間的區域。 The absorbent article 1 has a drain opening abutting domain S1, a front side domain S2, and a rear side domain S3. The excretory opening abutment field S1 is an area opposed to the user's excretory opening (for example, a vaginal opening). The excretory opening abutment field S1 is located in the lower part of the crotch when the absorbent article is attached to the underpants. That is, the excretory opening abutment field is disposed in the armpit of the installer, that is, in an area disposed between the legs of the wearer.

前側域S2，是較***口抵接域S1更位於前側。前側域S2的前端緣，是規定吸收性物品1的前端緣。後側域S3，是較***口抵接域S1更位於後側。後側域S3的後端緣，是規定吸收性物品1的後端緣。後側域S3的前後方向L的長度可形成的比***口抵接域S1的前後方向L的長度更長。 The front side field S2 is located on the front side more than the drain port abutment field S1. The front end edge of the front side region S2 defines the front end edge of the absorbent article 1. The rear side domain S3 is located further on the rear side than the drain opening abutment field S1. The rear end edge of the rear side region S3 defines the rear end edge of the absorbent article 1. The length of the front-back direction L of the rear side region S3 can be formed longer than the length of the front-rear direction L of the drain-port contact region S1.

在***口抵接域S1可設有後述的翼片3。又，在後側域S3可設有朝寬邊方向W的外側鼓出的臀翼4。 A flap 3 to be described later may be provided in the drain opening abutment field S1. Further, the hip region 4 which is bulged outward in the widthwise direction W may be provided in the rear side region S3.

翼片3的前端緣，是藉由翼片3的根部被規定，且是相當於最朝寬邊方向W的內側凹陷的2個部分中位於前側的部分。翼片3的前端緣也可規定***口抵接域S1與前側域S2的邊界。翼片3的後端緣，是藉由翼片3的根部被規定，且是相當於最朝寬邊方向W的內側凹陷的2個部分中位於後側的部分。翼片3的後端緣，是位在 ***口抵接域S1與後側域S3之間即可。於此，將前後方向L中的翼片3的前端緣與翼片3的後端緣之間的區域稱為「翼片域」。在具有翼片的吸收性物品，***口抵接域S1，是成為與翼片域實質上相同的區域。因此，在本說明書，「***口抵接域S1」的敘述，必須留意是可替換成「翼片域」。 The front end edge of the flap 3 is defined by the root portion of the flap 3 and is located on the front side of the two portions which are recessed toward the inner side in the most wide direction W.

(6)裝用中的吸收性物品 (6) Absorbent articles in use

接著，參照圖5~圖8，針對裝用中的吸收性物品的形狀進行說明。圖5是使用中的吸收性物品的立體圖。圖6是使用中的吸收性物品沿著圖1的6A-6A線的模式剖視圖。圖7是使用中的吸收性物品沿著圖1的7A-7A線的模式剖視圖。圖8是使用中的吸收性物品沿著圖1的3A-3A線的模式剖視圖。此外，圖6、7，是用二點鏈線表示裝用者的身體的形狀的線條。 Next, the shape of the absorbent article in use will be described with reference to Figs. 5 to 8 . Fig. 5 is a perspective view of an absorbent article in use. Figure 6 is a schematic cross-sectional view of the absorbent article in use taken along line 6A-6A of Figure 1 . Figure 7 is a schematic cross-sectional view of the absorbent article in use taken along line 7A-7A of Figure 1 . Figure 8 is a schematic cross-sectional view of the absorbent article in use taken along line 3A-3A of Figure 1 . In addition, FIGS. 6 and 7 are lines which express the shape of the body of the wearer by a two-dot chain line.

裝用作為生理用衛生棉的吸收性物品1的時候，吸收性物品1被固定在內褲S。吸收性物品1的***口抵接域S1，是被裝設者的兩腿夾著，而承受從寬邊方向W的外側朝向寬邊方向W的內側的力。 When the absorbent article 1 as a sanitary napkin is used, the absorbent article 1 is fixed to the undergarment S. The drain opening abutment region S1 of the absorbent article 1 is a force that is sandwiched between the legs of the installer and is received from the outer side in the wide side direction W toward the inner side in the wide side direction W.

沿著吸收性物品1的寬邊方向W的裝用者的身體的剖面形狀，在***附近與臀部附近不同。具體而言，裝用者的***的陰裂(經血出來的***口附近)附近的 身體的剖面形狀，是大***較大***的根部更突出，且是朝吸收性物品1側突出的凸形狀。在該裝用者的***域，吸收性物品的***口抵接域S1對置被配置。在裝用者的***，***口抵接域S1的吸收芯31，尤其沿著身體配置中高部33，而可抑制***中的體液的漏出(參照圖6)。 The cross-sectional shape of the body of the wearer along the widthwise direction W of the absorbent article 1 is different from the vicinity of the buttocks in the vicinity of the underarm. Specifically, the wearer’s underarm rupture (near the vaginal opening from the blood) The cross-sectional shape of the body is that the root of the labia majora of the labia majora is more prominent, and is a convex shape that protrudes toward the side of the absorbent article 1. In the armpit field of the wearer, the drain opening abutment field S1 of the absorbent article is disposed to face each other. Under the armpit of the wearer, the excretory opening abuts the absorbent core 31 of the field S1, and particularly the middle portion 33 along the body, and the leakage of the body fluid in the underarm can be suppressed (see Fig. 6).

在較裝用者的大***位於後方的會陰部更位於後方，是肛門、股溝位於此。較該會陰部更後方附近的身體的剖面形狀，是寬邊方向中心凹陷的形狀。在該裝用者的臀部，吸收性物品的後側域S3對置被配置。 It is located at the rear of the perineum at the rear of the larger labia of the wearer, where the anus and the sulcus are located. The cross-sectional shape of the body near the rear of the perineal portion is a shape in which the center of the broad side is concave. The back side field S3 of the absorbent article is disposed opposite to the buttocks of the wearer.

在後側域S3形成有沿著中心線CL朝前後方向L延伸的第2低基重區域42。因此，寬邊方向W中的後側域S3的中心，是藉由從吸收性物品的外側朝內側的力容易朝向裝用者的身體突出(參閱圖7)。藉此，吸收性物品1在後側域S3可配合裝用者的股溝形狀變形。其結果，裝用者在臀部也可獲得與吸收性物品1舒服的貼合感。 A second low basis weight region 42 extending in the front-rear direction L along the center line CL is formed in the rear side region S3. Therefore, the center of the rear side region S3 in the wide-side direction W is easily protruded toward the body of the wearer by the force from the outer side to the inner side of the absorbent article (see FIG. 7). Thereby, the absorbent article 1 can be deformed in the rear side domain S3 in accordance with the shape of the groove of the wearer. As a result, the wearer can obtain a comfortable feeling of adhesion to the absorbent article 1 on the buttocks.

於此，吸收性物品1在***口抵接域S1與後側域S3欲配合裝用者的身體的形狀變化成不同的形狀。第1低基重區域41抑制***口抵接域S1中的吸收體30的變形對後側域S3中的吸收體30造成的變形的影響。亦即，吸收性物品藉由第1低基重區域41，在***口抵接域S1與後側域S3容易獨立變形。 Here, the shape of the absorbent article 1 in the excretory opening abutment field S1 and the rear side domain S3 to be fitted with the wearer's body is changed to a different shape. The first low basis weight region 41 suppresses the influence of the deformation of the absorber 30 in the drain port abutment region S1 on the deformation of the absorber 30 in the rear side region S3. That is, the absorbent article is easily deformed independently by the first low basis weight region 41 in the drain opening contact region S1 and the rear side region S3.

又，夜用的生理用衛生棉在仰躺的睡姿下被 使用的情況多。在裝用者仰躺睡覺的姿勢，在臀部與吸收性物品1之間容易產生間隙。 In addition, the sanitary napkin for night use is placed in a sleeping position on the back. There are many cases of use. In the posture in which the wearer is lying on his back, a gap is easily generated between the buttocks and the absorbent article 1.

具體而言，因為裝用者的臀部在睡覺姿勢被床壓潰，所以，藉由來自該臀部的力吸收性物品1的後側域S3會有朝***口抵接域S1稍微移動的情況。藉此，在***口抵接域S1與後側域S3之間的區域附近，產生在前後方向L變形。藉由該變形，在***口抵接域S1與後側域S3之間的區域附近，在吸收性物品1與臀部之間可能會產生間隙。 Specifically, since the buttocks of the wearer are crushed by the bed in the sleeping position, the rear side region S3 of the force absorbent article 1 from the buttocks may slightly move toward the drain opening contact region S1. Thereby, deformation in the front-rear direction L occurs in the vicinity of the region between the excretory opening abutment region S1 and the rear side region S3. By this deformation, a gap may be generated between the absorbent article 1 and the buttocks in the vicinity of the region between the excretory opening abutment region S1 and the rear side region S3.

在臀部與吸收性物品之間間隙產生的話，會有經血順從身體流到背側後方，而從吸收性物品的後面漏出的顧慮。又，裝用者感覺到經血傳到身體的情況時，會有感受的不安感的情況。 When a gap is formed between the buttocks and the absorbent article, there is a concern that the menstrual blood flows from the body to the back side and leaks from the back of the absorbent article. Moreover, when the wearer feels that the menstrual blood is transmitted to the body, there is a feeling of uneasiness.

一實施形態的吸收性物品1，是至少在第1低基重區域41之處存在肌膚面薄片10的非接合區域46。因此，吸收性物品的後側域S3朝***口抵接域S1移動時，肌膚面薄片10的非接合區域46朝向裝用者的身體突出(參照圖8的符號「47」)。該肌膚面薄片10的突出部47埋在與裝用者的身體之間的間隙。藉此，即使在睡覺姿勢，也可抑制經血順從身體流到背側後方的情況。 In the absorbent article 1 of one embodiment, the non-joining region 46 of the skin patch 10 is present at least in the first low basis weight region 41. Therefore, when the rear side region S3 of the absorbent article moves toward the drain opening contact region S1, the non-joining region 46 of the skin surface sheet 10 protrudes toward the body of the wearer (see the symbol "47" in Fig. 8). The protruding portion 47 of the skin-surface sheet 10 is buried in a gap with the body of the wearer. Thereby, even in the sleeping position, it is possible to suppress the menstrual blood from flowing to the back side of the body.

如前述，因為裝用者的臀部在睡覺姿勢被床 壓潰，所以，藉由來自該臀部的力吸收性物品1的後側域S3會有朝***口抵接域S1稍微移動的情況。藉此，在***口抵接域S1與後側域S3之間的區域附近，產生在前後方向L變形。藉由該變形，在***口抵接域S1與後側域S3之間的區域附近，在吸收性物品1與臀部之間可能會產生間隙。在本實施形態，至少在第1低基重區域S1之處存在肌膚面薄片10的非接合區域46。因此，吸收性物品的後側域S3朝***口抵接域S1移動時，肌膚面薄片10的非接合區域46朝向裝用者的身體突出(參照圖8的符號「47」)。該肌膚面薄片10的突出部47埋在與裝用者的身體之間的間隙。藉此，即使在睡覺姿勢，也可抑制經血順從身體流到背側後方的情況。其結果，能夠抑制體液的漏出。又，在睡覺姿勢，能防止體液從裝用者的臀部傳到背部的情況，能減輕對裝用者造成的不安感。 As mentioned above, because the wearer’s buttocks are bed in a sleeping position Since the crushing is performed, the rear side region S3 of the force absorbent article 1 from the buttocks may slightly move toward the drain opening contact region S1. Thereby, deformation in the front-rear direction L occurs in the vicinity of the region between the excretory opening abutment region S1 and the rear side region S3. By this deformation, a gap may be generated between the absorbent article 1 and the buttocks in the vicinity of the region between the excretory opening abutment region S1 and the rear side region S3. In the present embodiment, the non-joining region 46 of the skin patch 10 is present at least in the first low basis weight region S1. Therefore, when the rear side region S3 of the absorbent article moves toward the drain opening contact region S1, the non-joining region 46 of the skin surface sheet 10 protrudes toward the body of the wearer (see the symbol "47" in Fig. 8). The protruding portion 47 of the skin-surface sheet 10 is buried in a gap with the body of the wearer. Thereby, even in the sleeping position, it is possible to suppress the menstrual blood from flowing to the back side of the body. As a result, leakage of body fluid can be suppressed. Moreover, in the sleeping position, it is possible to prevent the body fluid from passing from the buttocks of the wearer to the back, and it is possible to reduce the feeling of uneasiness caused to the wearer.

再者如前述，第2低基重區域42在裝用中朝向裝用者的肌膚側突出。第2低基重區域42因為在後側域S3沿著前後方向L延伸，所以容易沿著裝用者的股溝貼合。再者如前述，吸收性物品藉由第1低基重區域41在***口抵接域S1與後側域S3容易獨立變形。亦即，吸收性物品1在***口抵接域S1與後側域S3獨立變形，能在***口抵接域S1與後側域S3的兩方配合身體的形狀貼合。如以上，吸收性物品1順從裝用者的身體，對於裝用者可給予舒服的貼合感。 Further, as described above, the second low basis weight region 42 protrudes toward the skin side of the wearer during the attachment. Since the second low basis weight region 42 extends in the front-back direction L in the rear side region S3, it is easy to stick along the groove of the wearer. Further, as described above, the absorbent article is easily deformed independently by the first low basis weight region 41 in the drain opening contact region S1 and the rear side region S3. In other words, the absorbent article 1 is independently deformed in the excretory opening abutment field S1 and the rear side domain S3, and can be bonded to the shape of the body in the excretory opening abutment field S1 and the rear side domain S3. As described above, the absorbent article 1 conforms to the body of the wearer, and gives the wearer a comfortable fit.

根據一實施形態，肌膚面薄片10包含：表面薄片11、被設在表面薄片11與吸收體30之間的第二薄片13。第二薄片13的親水度至少在後述的非接合區域46較表面薄片11的親水度更高。藉此，第二薄片13在非接合區域46，亦即至少在第1低基重區域41可隔著表面薄片11吸入體液。因此，可僅可能將表面薄片11保持在乾的狀態，而可減輕裝用者的不舒適感。 According to one embodiment, the skin surface sheet 10 includes a surface sheet 11 and a second sheet 13 provided between the surface sheet 11 and the absorber 30. The hydrophilicity of the second sheet 13 is higher than that of the surface sheet 11 at least in the non-joining region 46 to be described later. Thereby, the second sheet 13 can suck the body fluid in the non-joining region 46, that is, at least in the first low basis weight region 41 via the surface sheet 11. Therefore, it is possible to keep only the surface sheet 11 in a dry state, and it is possible to alleviate the discomfort of the wearer.

根據一實施形態，肌膚面薄片10至少在第1低基重區域41具有朝前後方向L延伸的壓榨部88。在非接合區域46藉由壓榨部88使肌膚面薄片10沿著前後方向L的剛性變高。藉此，肌膚面薄片10的非接合區域46容易朝向裝用者的肌膚突出，且可容易維持突出的狀態。該壓榨部88從外部不易視認第1低基重區域41，視覺效果也優。 According to one embodiment, the skin surface sheet 10 has the press portion 88 extending in the front-rear direction L at least in the first low basis weight region 41. In the non-joining region 46, the rigidity of the skin surface sheet 10 in the front-rear direction L is increased by the press portion 88. Thereby, the non-joining region 46 of the skin-surface sheet 10 easily protrudes toward the skin of the wearer, and the protruding state can be easily maintained. The press portion 88 is difficult to visually recognize the first low basis weight region 41 from the outside, and the visual effect is also excellent.

根據一實施形態，肌膚面薄片10至少在第1低基重區域41具有朝相對於前後方向L傾斜的方向延伸的壓榨部88。此時，也與前述的實施形態同樣，肌膚面薄片10的非接合區域46容易朝向裝用者的肌膚突出，且可容易維持突出的狀態。又，一般來說，肌膚面薄片10的纖維方向，是朝向吸收性物品1的前後方向L。藉由在從肌膚面薄片10的纖維方向傾斜的方向形成壓榨部88，可抑制肌膚面薄片10的強度的降低。 According to one embodiment, the skin surface sheet 10 has the press portion 88 that extends in a direction inclined with respect to the front-rear direction L at least in the first low basis weight region 41. At this time, similarly to the above-described embodiment, the non-joining region 46 of the skin-surface sheet 10 easily protrudes toward the skin of the wearer, and the protruding state can be easily maintained. Moreover, in general, the fiber direction of the skin surface sheet 10 is oriented toward the front-back direction L of the absorbent article 1. By forming the press portion 88 in a direction inclined from the fiber direction of the skin surface sheet 10, it is possible to suppress a decrease in the strength of the skin surface sheet 10.

根據一實施形態，在夾著前述第2低基重區域42的兩側形成有沿著前後方向L延伸的一對的長邊壓 榨部82。一對的長邊壓榨部82因為剛性較高，而成為吸收體30的變形基點。被夾在一對的長邊壓榨部82之間的第2低基重區域42更朝裝用者的身體側***。藉此，可提供一種更順從裝用者的身體，對於裝用者可給予更舒服的貼合感的吸收性物品。 According to one embodiment, a pair of long side pressures extending in the front-rear direction L are formed on both sides of the second low basis weight region 42 interposed therebetween. Press section 82. The pair of long side press portions 82 become a deformation base point of the absorber 30 because of high rigidity. The second low basis weight region 42 sandwiched between the pair of long side press sections 82 is further swelled toward the body side of the wearer. Thereby, it is possible to provide an absorbent article which is more conformable to the wearer's body and which gives the wearer a more comfortable fit.

根據一實施形態，吸收體30，是在後側域S3具有從第2低基重區域42延伸到寬邊方向W的外側的第3低基重區域43。第3低基重區域43，是形成沿著寬邊方向W延伸的變形基點。後側域S3的吸收芯31因為可以第3低基重區域43為基點變形，所以，吸收性物品1沿著身體前後方向L的曲線更容易貼合。尤其，如圖7所示，第2低基重區域42沿著股溝突出時，使後側域S3沿著沿身體的前後方向L的曲線不易變形。即使此時，藉由成為變形基點的第3低基重區域43，可使後側域S3配合沿著身體的前後方向L的曲線容易變形。藉此，可提供一種更順從裝用者的身體，對於裝用者可給予更舒服的貼合感的吸收性物品。 According to one embodiment, the absorber 30 has the third low basis weight region 43 extending from the second low basis weight region 42 to the outside in the widthwise direction W in the rear side region S3. The third low basis weight region 43 is a deformation base point that extends in the widthwise direction W. Since the absorbent core 31 of the rear side region S3 is deformable at the base point of the third low basis weight region 43, the absorbent article 1 is more easily bonded along the curve of the body longitudinal direction L. In particular, as shown in FIG. 7, when the second low basis weight region 42 protrudes along the sulcus, the curve of the rear side region S3 along the longitudinal direction L along the body is not easily deformed. Even at this time, by the third low basis weight region 43 which becomes the deformation base point, the rear side region S3 can be easily deformed in accordance with the curve along the front-rear direction L of the body. Thereby, it is possible to provide an absorbent article which is more conformable to the wearer's body and which gives the wearer a more comfortable fit.

根據一實施形態，具有被設在非肌膚面薄片20的非肌膚面側的黏著區域61、62、63、64。第1低基重區域41被配置在與黏著區域61、62、63、64不會重疊的區域。藉此，第1低基重區域41能進一步作為變形基點發揮功能。亦即，夾著第1低基重區域41相鄰的吸收芯31容易互相獨立動作。藉此，吸收體30配合裝用者的***及臀部的形狀更容易貼合。再者，在睡覺姿勢，吸收 性物品的後側域S3朝***口抵接域S1更容易移動。藉此，肌膚面薄片10的突出部47朝裝用者的身體更容易突出。 According to one embodiment, the adhesive regions 61, 62, 63, and 64 provided on the non-skin surface side of the non-skin surface sheet 20 are provided. The first low basis weight region 41 is disposed in a region that does not overlap the adhesion regions 61, 62, 63, and 64. Thereby, the first low basis weight region 41 can further function as a deformation base point. That is, the absorbent cores 31 adjacent to each other across the first low basis weight region 41 are easily operated independently of each other. Thereby, the absorber 30 is more easily attached to the shape of the armpit and the buttocks of the wearer. Furthermore, in the sleeping position, absorption The rear side domain S3 of the sexual article is more easily moved toward the drain opening abutment field S1. Thereby, the protruding portion 47 of the skin dough sheet 10 is more likely to protrude toward the wearer's body.

根據一實施形態，吸收體30，是具有被配置在***口抵接域S1的中高部33，即具有較被配置在後側域S3的吸收體30的厚度更厚的中高部33。藉此，肌膚面薄片10在較非接合區域46更前方的中高部33與吸收體30接合，在較非接合區域46更後方的較中高部33更薄的部分與吸收體30接合。因此，肌膚面薄片10在非接合區域46從後側欲朝向前側與往高之側傾斜。在此狀態，吸收性物品1的後側域S3朝***口抵接域S1移動的話，在肌膚面薄片10在非接合區域46更容易朝向裝用者的身體突出。 According to one embodiment, the absorber 30 has the middle-high portion 33 disposed in the drain-hole contact region S1, that is, the intermediate-high portion 33 having a thicker thickness than the absorber 30 disposed in the rear-side region S3. Thereby, the skin-surface sheet 10 is joined to the absorber 30 at the middle-high portion 33 which is further forward than the non-joining region 46, and is joined to the absorber 30 at a portion thinner than the middle-high portion 33 which is rearward than the non-joining region 46. Therefore, the skin surface sheet 10 is inclined from the rear side toward the front side and toward the high side in the non-joining region 46. In this state, when the rear side region S3 of the absorbent article 1 moves toward the drain opening contact region S1, the skin surface sheet 10 is more likely to protrude toward the wearer's body in the non-joining region 46.
