可是，在上述的吸收性物品，是有以下的問題點。 However, the above-mentioned absorbent article has the following problems.
安裝吸收性物品的***口抵接域時，吸收性物品的寬邊方向的中心沒有被配置在內褲的寬邊方向的中心、或吸收性物品的前後方向相對於內褲的前後方向偏移的話，不能讓後側域適當地和身體對置來進行配置。尤其，後側域因為後側域的前後方向的長度比較長，所以愈朝向後方位置偏移的量變大。因此，不能以覆蓋裝用者的臀部地配置吸收芯，會有洩漏發生的情況。 When the excretory abutment area of the absorbent article is attached, if the center of the absorbent article in the widthwise direction is not placed in the center of the underwear in the widthwise direction, or if the front-back direction of the absorbent article is shifted from the underwear-backward direction, Do not allow the rear side to be properly positioned against the body. In particular, since the length of the rear side domain in the front-rear direction is relatively long, the amount of displacement toward the rear side becomes larger. Therefore, the absorbent core cannot be arranged to cover the hips of the wearer, and leakage may occur.
又，沿著裝用者的臀部附近的寬邊方向的身體的剖面形狀，是左右的臀部***，該臀部間凹陷的形狀。若沒有順著該臀部間的凹陷配置吸收性物品的話，會有體液從裝用者的臀部的凹陷與吸收性物品的間隙露出發生的情況。 In addition, the cross-sectional shape of the body along the wide side direction near the hips of the wearer is a shape in which the left and right hips are raised and the hips are recessed. If the absorbent article is not arranged along the depression between the buttocks, the body fluid may be exposed from the gap between the depression of the user's buttocks and the absorbent article.

吸收芯31，是具有：寬邊縫隙41、前後縫隙42、以及輔助縫隙43。吸收芯31，是構成寬邊縫隙41、前後縫隙42、以及輔助縫隙43可使吸收芯31朝厚度方向T彎曲。 The absorbent core 31 includes a wide-side slit 41, a front-rear slit 42, and an auxiliary slit 43. The absorbent core 31 is configured such that the wide-side slit 41, the front-rear slit 42, and the auxiliary slit 43 can bend the absorbent core 31 in the thickness direction T.
寬邊縫隙41、前後縫隙42、以及輔助縫隙43的吸收材料的基重比周圍的吸收芯31的吸收材料的基重更低。周圍的吸收芯31，是指鄰接寬邊縫隙等的區域的吸收芯，例如，在***口抵接域S1鄰接寬邊縫隙41的吸收芯；以及在後側域S2鄰接寬邊縫隙41的吸收芯。此外，寬邊縫隙41、前後縫隙42以及輔助縫隙43，是只要吸收材料的基重比周圍的吸收芯31更低的區域即可，亦可基重為0的區域，也可設計上的基重是0，可是配置有從周圍的吸收芯31混入吸收材料的區域。 The basis weight of the absorbent material of the wide-side slit 41, the front and rear slits 42, and the auxiliary slit 43 is lower than that of the absorbent material of the surrounding absorbent core 31. The surrounding absorbent core 31 refers to an absorbent core adjacent to a region such as the wide-side slit, for example, an absorbent core adjacent to the wide-side slit 41 at the drainage abutment region S1; and an absorption adjacent to the wide-side slit 41 in the rear side S2. core. In addition, the wide-side slit 41, the front-rear slit 42 and the auxiliary slit 43 are regions in which the basis weight of the absorbent material is lower than that of the surrounding absorbent core 31, and the area in which the basis weight is 0 may also be designed. The weight is 0, but a region where the absorbent material is mixed from the surrounding absorbent core 31 is arranged.
本實施的形態的寬邊縫隙41、前後縫隙42、以及輔助縫隙43，是設計上的基重為0，且朝厚度方向貫穿吸收芯31。因此，在厚度方向T和寬邊縫隙41重疊的區域、和前後縫隙42重疊的區域、以及和輔助縫隙43重疊的區域，在肌膚面薄片10與非肌膚面薄片20之間沒有配置吸收材料。又，在厚度方向T和寬邊縫隙41重疊的區域、和前後縫隙42重疊的區域、以及和輔助縫隙43重疊的區域，肌膚面薄片10與非肌膚面薄片20沒有被接 合。 The wide side slit 41, the front and rear slits 42, and the auxiliary slit 43 of the embodiment of this embodiment have a design basis weight of 0 and penetrate the absorbent core 31 in the thickness direction. Therefore, in the area where the thickness direction T and the wide-side slit 41 overlap, the area where the front and rear slits 42 overlap, and the area where the auxiliary slit 43 overlaps, no absorbing material is disposed between the skin surface sheet 10 and the non-skin surface sheet 20. In addition, in the area where the thickness direction T and the wide-side slit 41 overlap, the area where the front and rear slits 42 overlap, and the area where the auxiliary slit 43 overlaps, the skin surface sheet 10 and the non-skin surface sheet 20 are not connected. Together.
又，在和寬邊縫隙41重疊的區域、和前後縫隙42重疊的區域、以及和輔助縫隙43重疊的區域，位在吸收芯31的肌膚對置面側的芯包層32與位在吸收芯31的非肌膚面側的芯包層32也可被接合，也可沒有被接合。例如，根據位在吸收芯31的肌膚對置面側的芯包層32與位在吸收芯31的非肌膚對向面側的芯包層32被接合的構造，可抑制吸收芯31的走樣。又，在和寬邊縫隙41重疊的區域、和前後縫隙42重疊的區域、以及和輔助縫隙43重疊的區域，表面薄片11與芯包層32也可被接合，也可沒有被接合。除此之外，在和寬邊縫隙41重疊的區域、和前後縫隙42重疊的區域、以及和輔助縫隙43重疊的區域，非肌膚面薄片20與芯包層32也可被接合，也可沒有被接合。 In the region overlapping the wide-side slit 41, the region overlapping the front and rear slits 42, and the region overlapping the auxiliary slit 43, the core cladding layer 32 located on the skin-opposing surface side of the absorbent core 31 and the absorbent core The core cladding layer 32 on the non-skin surface side of 31 may or may not be bonded. For example, according to the structure in which the core cladding layer 32 on the skin-opposing surface side of the absorbent core 31 and the core cladding layer 32 on the non-skin-opposing surface side of the absorbent core 31 are joined, the aliasing of the absorbent core 31 can be suppressed. The surface sheet 11 and the core cladding layer 32 may or may not be bonded in a region overlapping the wide-side slit 41, a region overlapping the front and rear slits 42, and a region overlapping the auxiliary slit 43. In addition, in the area overlapping the wide-side slit 41, the area overlapping the front and rear slits 42, and the area overlapping the auxiliary slit 43, the non-skin surface sheet 20 and the core cladding 32 may be joined or not. Being engaged.
寬邊縫隙41、前後縫隙42、以及輔助縫隙43，是成為剛性變化的邊界。具體而言，例如，比寬邊縫隙41更前側的區域的剛性、與比寬邊縫隙41更後側的區域的剛性不同。更詳細的是，比寬邊縫隙41更前側的區域的吸收材料的基重比寬邊縫隙41的吸收材料的基重更高。又，比寬邊縫隙41更後側的區域的吸收材料的基重比寬邊縫隙41的吸收材料的基重更高。 The wide-side slit 41, the front-back slit 42, and the auxiliary slit 43 are boundaries that become rigid. Specifically, for example, the rigidity of a region more forward than the wide-side slit 41 is different from the rigidity of a region more rearward than the wide-side slit 41. In more detail, the basis weight of the absorbent material in a region more forward than the wide-side slit 41 is higher than that of the wide-side slit 41. In addition, the basis weight of the absorbent material in a region further to the rear side than the wide-side slit 41 is higher than that of the wide-side slit 41.
寬邊縫隙41在***口抵接域S1與後側域S2之間，在寬邊方向W上延伸。寬邊縫隙41至少在寬邊方向上延伸即可，也可和寬邊方向平行的直線狀，也可不是 和寬邊方向平行，而是相對於寬邊方向傾斜的直線狀或曲線狀。本實施的形態的寬邊縫隙，是寬邊縫隙41的寬邊方向的中央朝後方突出的曲線形狀。更詳細的是，寬邊縫隙41的寬邊方向的中心比寬邊縫隙41的外側緣更位在後方。寬邊縫隙41的寬邊方向的中心，是朝向後方的凸狀。此外，寬邊縫隙的前後方向的長度，也可一定，也可變化。又，寬邊縫隙的前後方向的長度在10mm以上且50mm以下，更理想是寬邊隙縫的前後方向的長度在10mm以上且30mm以下。 The wide side slit 41 extends in the wide side direction W between the excretory port abutment region S1 and the rear side region S2. The wide side slit 41 may extend at least in the wide side direction, or may be a straight line parallel to the wide side direction, or may not be It is parallel to the broad side direction, but is linear or curved inclined with respect to the broad side direction. The wide-side slit of the embodiment has a curved shape in which the center of the wide-side direction of the wide-side slit 41 protrudes rearward. More specifically, the center of the wide-side slit 41 in the wide-side direction is more rearward than the outer edge of the wide-side slit 41. The center of the wide side slit 41 in the wide side direction is convex toward the rear. The length of the wide-side slit in the front-back direction may be constant or may be changed. The length of the wide-side slit in the front-rear direction is 10 mm or more and 50 mm or less, and the length of the wide-side slit in the front-rear direction is preferably 10 mm or more and 30 mm or less.
例如，寬邊縫隙41的前後方向的長度未滿10mm時，會有不能充分獲得緩衝寬邊縫隙41的前側的動作與寬邊縫隙41的後側的動作，或不能充分獲得分斷的作用的情況。又，寬邊縫隙41的前後方向的長度超過50mm時，除了會有緩衝寬邊縫隙41的前側的動作與寬邊縫隙41的後側的動作變大，或分斷的作用變大之外，會有作為吸收性物品的安心感減低的情況。 For example, if the length of the wide-side slit 41 in the front-rear direction is less than 10 mm, there may be cases in which it is impossible to sufficiently cushion the movement of the front side of the wide-side slit 41 and the movement of the rear side of the wide-side slit 41, or it may not be sufficient to obtain the breaking effect. Happening. When the length of the wide-side slit 41 in the front-back direction exceeds 50 mm, in addition to buffering the front side movement of the wide-side slit 41 and the rear side movement of the wide-side slit 41, or the breaking effect becomes large, There is a case where the peace of mind as an absorbent article is reduced.
又，寬邊縫隙41的寬邊方向的長度在25mm以上為理想。一般來說，夜用的生理用衛生棉的中高部33的寬邊方向的長度(基重比較高的部分的寬邊方向的長度)，在25mm以上30mm以下的情況較多。例如，中高部33在***口抵接域S1與後側域S2連續被形成的話，會有藉由該中高部使***口抵接域S1的作動在後側域S2進行連動。可是，藉由將寬邊縫隙41的寬邊方向的長度設在25mm以上，在前後方向將中高部33分斷，可抑制 ***口抵接域S1的動作和後側域S2連動的情況。 The width of the wide-side slit 41 in the width direction is preferably 25 mm or more. Generally, the length in the widthwise direction (the length in the widthwise direction of the portion having a relatively high basis weight) of the mid-high portion 33 of the night-use sanitary napkin is often 25 mm or more and 30 mm or less. For example, if the mid-high section 33 is continuously formed in the excretory port abutting region S1 and the rear side region S2, the action of the mid-high part to cause the excretory port abutting region S1 to be linked in the rear side S2. However, by setting the length in the widthwise direction of the widthwise slit 41 to 25 mm or more, and dividing the middle and high portions 33 in the front-rear direction, it is possible to suppress The case where the excretory port abuts on the field S1 and the rear side S2 are linked.
寬邊縫隙41也可被形成在吸收芯31的寬邊方向的全域，也可被形成在吸收芯的寬邊方向的一部分的區域。本實施的形態的寬邊縫隙41，是被形成在吸收芯31的寬邊方向全域。寬邊縫隙41的外側緣41E，是位在吸收芯31的外側緣31E。因此，***口抵接域S1的吸收芯31與後側域S2的吸收芯31，是因寬邊縫隙41在前後方向被分斷。此外，本實施的形態的吸收體30，是吸收芯31的外側緣與吸收體30的外側緣大致一致。因此，圖面上表示寬邊縫隙41的外側緣41E與吸收體30的外側緣一致。 The wide-side slit 41 may be formed in the entire area in the widthwise direction of the absorbent core 31, or may be formed in a part of the widthwise direction of the absorbent core. The wide-side slit 41 of the embodiment is formed in the entire widthwise direction of the absorbent core 31. The outer edge 41E of the wide-side slit 41 is located on the outer edge 31E of the absorbent core 31. Therefore, the excretory port abuts the absorbent core 31 of the domain S1 and the absorbent core 31 of the rear domain S2 because the wide-side slit 41 is divided in the front-rear direction. In addition, in the absorbent body 30 of the embodiment, the outer edge of the absorbent core 31 and the outer edge of the absorbent body 30 substantially coincide. Therefore, the outer edge 41E of the wide-side slit 41 shown in the drawing coincides with the outer edge of the absorber 30.
前後縫隙42在後側域S2朝前後方向L延伸。前後縫隙42，是至少只要朝前後方向延伸即可，也可和前後方向平行的直線狀，也可不是和前後方向平行，而是相對於前後方向傾斜的直線狀或曲線狀。前後縫隙42也可被形成在後側域S2的吸收芯31的前後方向L的全域，也可被形成在後側域S2的吸收芯31的前後方向的一部分的區域。前後縫隙42，在臀翼4比最位於寬邊方向的外側的最外緣部4E更延伸到後方為理想。本實施的形態的前後縫隙42，是被形成在後側域S2的吸收芯前後方向L的全域。前後縫隙42的前端緣，是和寬邊隙縫41相連，前後縫隙42的後端緣，是位在吸收芯的後端緣。因此，後側域S2的吸收芯31，是因前後縫隙42在寬邊方向被分斷。 The front-rear slit 42 extends in the front-rear direction L in the rear-side region S2. The front-rear slit 42 may extend at least in the front-rear direction, may be a linear shape parallel to the front-rear direction, or may not be parallel to the front-rear direction, but may be a straight or curved shape inclined with respect to the front-rear direction. The front and rear slits 42 may be formed in the entire area in the front-back direction L of the absorbent core 31 in the rear side region S2, or may be formed in a part of the front-back direction in the absorbent core 31 in the rear side region S2. The front-rear slit 42 preferably extends to the rear in the hip wing 4 more than the outermost edge portion 4E, which is located on the outermost side in the widthwise direction. The front-rear slit 42 of the embodiment is the entire area of the absorbent core front-rear direction L formed in the rear-side domain S2. The front edge of the front-rear slit 42 is connected to the wide-edge slit 41, and the rear edge of the front-rear slit 42 is located at the rear edge of the absorbent core. Therefore, the absorbent core 31 of the rear side region S2 is divided by the front and rear slits 42 in the wide side direction.
又，前後縫隙42的前端緣，是比從翼片3的前後方向的中心3LC到30mm後方的位置更位於後方為理想。又，前後縫隙42的後端緣，是比從翼片3的前後方向的中心3LC到200mm後方的位置更位於後方為理想。前後縫隙42的前後方向的長度在150mm以上為理想。在沿著裝用者的身體的前後方向的剖面，臀部間的溝，是從越過會陰部附近開始存在到尾骨。根據這樣的前後縫隙42，以前後縫隙為頂點的凸狀的變形容易被配置在臀部間的溝。 The front end edge of the front-rear slit 42 is preferably located further rearward than the position from the center 3LC in the front-rear direction of the fin 3 to a position 30 mm rearward. The rear end edge of the front-rear slit 42 is preferably located further rearward than the position from the center 3LC in the front-rear direction of the flap 3 to a position 200 mm rearward. The length of the front-rear slit 42 in the front-rear direction is preferably 150 mm or more. In the cross section along the front-back direction of the wearer's body, the groove between the buttocks exists from the vicinity of the perineum to the coccyx. According to such a front-to-back slit 42, the convex deformation in which the front-to-back slit is an apex is easily placed in the groove between the buttocks.
又，前後縫隙42的寬邊方向的長度，是在1mm以上且15mm以下。例如，前後縫隙42的寬邊方向的長度未滿1mm時，以前後縫隙42為頂點呈凸狀變形的時候，夾著寬邊隙縫被配置的吸收芯31彼此干涉，而不易穩定地變形成凸狀。又，前後縫隙42的寬邊方向的長度超過15mm時，以前後縫隙42作為頂點的凸狀的變形部分被配置在臀部間的間隙時，因為在凸狀的變形部分吸收芯不存在，所以會有體液的吸收草率的情形。 The length of the front-back slit 42 in the width direction is 1 mm or more and 15 mm or less. For example, when the length in the widthwise direction of the front and rear slits 42 is less than 1 mm, when the front and rear slits 42 are convexly deformed at the apex, the absorbent cores 31 disposed across the wide edge slits interfere with each other, and it is not easy to steadily become convex. shape. When the length in the widthwise direction of the front and rear slits 42 exceeds 15 mm, when the convex deformed portion at the front and rear slits 42 is arranged in the gap between the buttocks, the absorbent core does not exist in the convex deformed portion. The absorption of body fluids may be hastily.
後側域S2的吸收芯31，是具有：第1區域311、與分別位在第1區域311的寬邊方向的外側的第2區域312及第3區域313。在圖1表示第1區域311、第2區域312及第3區域313的寬邊方向的範圍。第1區域311、第2區域312及第3區域313，是在寬邊方向將後側域S2的吸收芯31予以3等分的區域。第1區域311，是3等分的區域中位在寬邊方向中央的區域。第2區域 312，是3等分的區域中位在寬邊方向的一方之側部的區域。第3區域313，是3等分的區域中位在寬邊方向的另一方之側部的區域。此外，在後側域S2的吸收芯的寬邊方向的長度變化的構造，是作為在寬邊方向將鄰接寬邊縫隙41的吸收芯31予以3等分的區域。 The absorbent core 31 of the rear side region S2 includes a first region 311 and a second region 312 and a third region 313 which are positioned outside the first region 311 in the width direction. FIG. 1 shows the widthwise ranges of the first region 311, the second region 312, and the third region 313. The first region 311, the second region 312, and the third region 313 are regions in which the absorbent core 31 of the rear side region S2 is divided into three equal portions in the broad side direction. The first area 311 is an area located in the center of the width direction among the three equally divided areas. Zone 2 312 is a region located on the side of one of the three sides in the widthwise direction. The third area 313 is an area located on the other side of the wide side direction among the three equally divided areas. The structure in which the length of the absorbent core in the widthwise direction in the rear side region S2 is changed is a region in which the absorbent core 31 adjacent to the widthwise slit 41 is divided into three equal parts in the widthwise direction.
前後縫隙42，是被設在第1區域311。前後縫隙42也可被配置在吸收性物品1的寬邊方向W的中心。前後縫隙42，是構成後側域S2的吸收芯31可朝厚度方向T彎曲，更詳細的是，構成後側域S2的吸收芯31可朝裝用者側***。前後縫隙42，是構成曲部。 The front and rear slits 42 are provided in the first region 311. The front-rear slit 42 may be arranged at the center of the widthwise direction W of the absorbent article 1. The front and rear slits 42 are such that the absorbent core 31 constituting the rear side domain S2 can be bent in the thickness direction T. More specifically, the absorbent core 31 constituting the rear side domain S2 can be raised toward the wearer's side. The front and rear slits 42 constitute a curved portion.
作為曲部的前後縫隙42，是構成從吸收性物品的肌膚對置面側可視認。從吸收性物品的肌膚對置面側可視認前後縫隙42的狀態，是只要裝設者可掌握前後縫隙42的位置的狀態即可，而不只經由被配置在前後縫隙42的肌膚對置面側的表面薄片11可視認前後縫隙42的狀態，並包含藉由位在前後縫隙的非肌膚對置面側的裏面薄片21可視認前後縫隙42的位置的狀態的概念。亦即，前後縫隙42也可構成經由後述的識別部70可視認。 The front-rear slit 42 as the curved portion is configured to be visible from the skin facing surface side of the absorbent article. The state of the front and rear slits 42 can be visually recognized from the skin facing surface side of the absorbent article, as long as the installer can grasp the position of the front and rear slits 42, and not only through the skin facing surface side of the front and rear slits 42. The front surface sheet 11 can visually recognize the state of the front and rear slits 42 and includes the concept that the position of the front and rear slits 42 can be visually recognized by the inner sheet 21 located on the non-skin facing surface side of the front and rear slits. That is, the front-rear slit 42 may be configured to be visually recognized by a recognition unit 70 described later.
寬邊縫隙41與前後縫隙42相連。因此，在俯視觀看，***口抵接域S1的吸收芯31、後側域S2的寬邊方向W的一方側的吸收芯31(例如，位在裝用者的左側的吸收芯)、以及後側域S2的寬邊方向W的另一方側的吸收芯31(例如，位在裝用者的右側的吸收芯)，是被分斷的。此外，寬邊縫隙41與前後縫隙42也可分離。 The wide-side slit 41 is connected to the front and rear slits 42. Therefore, in a plan view, the excretory port abuts the absorbent core 31 of the domain S1, the absorbent core 31 on one side of the widthwise direction W of the rear domain S2 (for example, the absorbent core located on the left side of the wearer), and the rear The absorbent core 31 (for example, the absorbent core located on the right side of the wearer) on the other side in the widthwise direction W of the side region S2 is divided. In addition, the wide-side slit 41 and the front-rear slit 42 may be separated.
輔助縫隙43，是和前後縫隙42相連，且從前後縫隙42朝寬邊方向W的外側延伸。輔助縫隙43，是分別朝前後縫隙42的寬邊方向的兩側延伸。輔助縫隙43至少只要朝寬邊方向延伸即可，也可和寬邊方向平行的直線狀，也可不是和寬邊方向平行，而是相對於寬邊方向傾斜的直線狀或曲線狀。輔助縫隙43，是在前後方向L分開間隔設置複數個。輔助縫隙43的外側緣，是比後側域S2的吸收芯31的外側緣31E更位在寬邊方向W的內側。亦即，在輔助縫隙43的寬邊方向的外側，是配置有吸收材料。此外，輔助縫隙43也可延伸到後側域S2的吸收芯31的外側緣31E。輔助縫隙43，是從寬幅方向W的外側愈朝向寬邊方向的內側(前後縫隙42側)愈朝後側延伸。 The auxiliary slit 43 is connected to the front and rear slits 42 and extends from the front and rear slits 42 to the outside in the widthwise direction W. The auxiliary slits 43 extend toward both sides of the widthwise direction of the front and rear slits 42, respectively. The auxiliary slit 43 may extend at least in the broad side direction, and may be a straight line parallel to the broad side direction, or may not be parallel to the broad side direction, but may be a straight line or a curved shape inclined with respect to the broad side direction. The auxiliary slits 43 are provided at plural intervals in the front-rear direction L. The outer edge of the auxiliary slit 43 is located more inward than the outer edge 31E of the absorbent core 31 in the rear side region S2 in the widthwise direction W. That is, an absorbing material is arranged on the outer side in the width direction of the auxiliary slit 43. In addition, the auxiliary slit 43 may extend to the outer edge 31E of the absorbent core 31 in the rear side region S2. The auxiliary slit 43 extends from the outside in the widthwise direction W toward the inside in the widthwise direction (the front-rear slit 42 side) toward the rear side.
輔助縫隙43，是以構成後側域S2的吸收芯31朝厚度方向彎曲的變形基點的方式被構成。輔助縫隙43，是構成輔助曲部。此外，曲部及輔助曲部，不只有縫隙，亦可由其他的構造所構成。例如，曲部及輔助曲部，至少也可藉由將吸收芯朝厚度方向壓榨的壓榨部所構成，亦可藉由因吸收芯的基重與周圍不同而使剛性不同的區域所構成，也可藉由凹部與凸部的咬合所形成的壓花構成。 The auxiliary slit 43 is configured so that the absorbent core 31 constituting the rear side region S2 is deformed by a deformation base point. The auxiliary slit 43 constitutes an auxiliary curved portion. In addition, the curved portion and the auxiliary curved portion may be composed of not only a gap but also other structures. For example, the curved portion and the auxiliary curved portion may be constituted by at least a pressing portion that presses the absorbent core in the thickness direction, or may be constituted by a region having different rigidities due to the basis weight of the absorbent core and its surroundings. It can be formed by embossing formed by the engagement between the concave portion and the convex portion.

In addition, the flap 3 and the hip wing 4 may be provided with an absorbent material.
如圖2所示，在非肌膚面薄片20的非肌膚對置面，是設有塗佈了將吸收性物品固定在內褲S用的黏著劑的黏著區域60。黏著區域60，是具有：被配置在吸收芯31的非肌膚對置面側的第1本體黏著區域61及第2本體黏著區域62；被配置在翼片3的翼片黏著區域63；以及被配置在臀翼4的臀翼黏著區域64。 As shown in FIG. 2, the non-skin facing surface of the non-skin face sheet 20 is provided with an adhesion region 60 coated with an adhesive for fixing the absorbent article to the undergarment S. The adhesion region 60 includes a first body adhesion region 61 and a second body adhesion region 62 arranged on the non-skin facing surface side of the absorbent core 31, a flap adhesion region 63 arranged on the flap 3, and The hip wing adhesion area 64 is arranged in the hip wing 4.
第1本體黏著區域61，是與第2本體黏著區域62在前後方向分離，且比第2本體黏著區域62更被配置在前方。第1本體黏著區域61，是在寬邊縫隙41更前側跨***口抵接域S1與前側域S3被配置。第2本體黏著區域62，是在寬邊縫隙41更後側被配置在後側域S2。 The first main body adhesive region 61 is separated from the second main body adhesive region 62 in the front-back direction, and is disposed more forward than the second main body adhesive region 62. The first main body adhesion region 61 is disposed across the drain opening abutting the region S1 and the front region S3 at the front side of the wide-side slit 41. The second body adhesion region 62 is arranged further behind the wide-side slit 41 in the rear region S2.
寬邊縫隙41及前後縫隙42，在厚度方向T沒有重疊在黏著區域60。換言之，在俯視觀看在配置有寬邊縫隙41及前後縫隙的區域沒有設置黏著區域60。再者，從前後縫隙42朝後方延伸的區域，在厚度方向沒有重疊在黏著區域60。又，在翼片3及臀翼4，是設有黏著區域60。 The wide-side slit 41 and the front-rear slit 42 do not overlap the adhesion region 60 in the thickness direction T. In other words, the adhesive region 60 is not provided in a region where the wide-side slit 41 and the front-rear slit are arranged in a plan view. The region extending rearward from the front and rear slits 42 does not overlap the adhesion region 60 in the thickness direction. In addition, the flaps 3 and the buttocks 4 are provided with an adhesion area 60.
黏著區域60在使用前的狀態，藉由剝離薄片 65被覆蓋。剝離薄片65，是防止使用前接著劑劣化的情況。剝離薄片65，是使用時由裝用者所剝離。此外，在不具有剝離薄片的吸收性物品，也可構成藉由個別包裝吸收性物品的包裝薄片防止使用前接著區域劣化的情況。 The state of the adhesive region 60 before use, by peeling the sheet 65 are covered. The release sheet 65 prevents deterioration of the adhesive before use. The peeling sheet 65 is peeled by the user during use. In addition, an absorbent article without a release sheet may be configured to prevent the deterioration of the area immediately before use by packaging the absorbent article individually.
吸收性物品1，是具有識別部70。識別部70，是從吸收性物品的肌膚對置面側可視認作為非肌膚面薄片的裏面薄片21的區域。識別部70在俯視觀看配置有裏面薄片21，且為沒有藉由吸收體30覆蓋裏面薄片21的區域。例如，識別部70，是設有吸收芯的寬邊縫隙41的區域；設有前後縫隙42的區域；以及設有輔助縫隙43的區域。又，識別部70，是在比吸收體30更位於寬邊方向的外側配置有裏面薄片21的區域；以及在比吸收體30更位於前後方向L的外側配置有裏面薄片21的區域。在比吸收體30更位於寬邊方向W的外側配置有裏面薄片21的區域，是被配置在翼片3的寬邊方向W的內側。因此，能在翼片3的寬邊方向W的內側設置識別部70。又，在後側域S2，是沿著前後方向L配置有和前後縫隙42對應的識別部；以及比前後縫隙42及吸收體30更位於寬邊方向的兩外側的識別部。比前後縫隙42及吸收體30更位於寬邊方向的兩外側的識別部，是鄰接於吸收芯31的外側緣，且比臀翼的最外緣部4E更位於寬邊方向的內側。如此，識別部70是分別被配置在曲部(前後縫隙42)的寬邊方向的兩外側，各識別部70，是朝前後方向L延伸。此外，曲部及識別部70至少只要朝前後方向延伸 即可，也可和前後方向平行的直線狀，也可不是和前後方向平行，而是相對於前後方向傾斜的直線狀或曲線狀。 The absorbent article 1 includes a recognition portion 70. The identification portion 70 is a region of the back sheet 21 that can be viewed as a non-skin sheet from the skin facing surface side of the absorbent article. The recognition unit 70 is provided with the back sheet 21 in a plan view, and is an area where the back sheet 21 is not covered by the absorber 30. For example, the identification portion 70 is an area where the wide-side slit 41 of the absorbent core is provided; an area where the front-rear slit 42 is provided; and an area where the auxiliary slit 43 is provided. The identification unit 70 is a region where the inner sheet 21 is disposed outside the absorber 30 in the widthwise direction, and a region where the inner sheet 21 is disposed outside the absorber 30 in the front-back direction L. A region in which the inner sheet 21 is disposed outside the absorbent body 30 in the widthwise direction W is disposed inside the flap 3 in the widthwise direction W. Therefore, the identification part 70 can be provided in the width direction W of the flap 3. As shown in FIG. Further, in the rear region S2, identification portions corresponding to the front-rear slit 42 are arranged along the front-rear direction L; and the identification portions located on both outer sides in the broader direction than the front-rear slit 42 and the absorber 30. The identification portions located on both outer sides in the widthwise direction than the front and rear slits 42 and the absorbent body 30 are adjacent to the outside edge of the absorbent core 31 and are located inward of the widthwise direction than the outermost edge portion 4E of the hip wing. As described above, the identification portions 70 are disposed on both outer sides in the widthwise direction of the curved portion (front-rear slit 42), and the identification portions 70 extend in the front-rear direction L. In addition, the curved portion and the identification portion 70 need only extend at least in the front-rear direction. That is, it may be a straight line parallel to the front-back direction, or a straight line or a curved shape which is not parallel to the front-back direction, but inclined with respect to the front-back direction.
此外，本說明書中的「吸收體的基重及密度」的測量，是藉由以下的測量方法所進行者。 In addition, the measurement of "basis weight and density of an absorber" in this specification was performed by the following measurement method.
當吸收性物品1被封入在包裝件等的時候，使用從包裝件取出，並在這樣的狀態下在20℃±2℃、相對濕度60%±5%RH的環境下放置12小時後的樣本。 When the absorbent article 1 is enclosed in a package or the like, use the sample taken out from the package and left in such a state in an environment of 20 ° C ± 2 ° C and relative humidity 60% ± 5% RH for 12 hours. .
在包裝體所包裝的吸收性物品開封包裝體，展開被折疊的吸收性物品，測量測量基重及密度的部分的厚度及面積。接著，從吸收性物品切出測量基重及密度的部分，來測量所切出的部分的重量。接著，從切出的部分去除表面薄片及裏面薄片等吸收體以外的部分，測量吸收體的重量。依據吸收體的重量、與測量基重及密度的部分的面積算出基重。依據基重及厚度算出密度。 Unpack the absorbent article packed in the package, unfold the folded absorbent article, and measure the thickness and area of the portion where the basis weight and density are measured. Next, a part for measuring the basis weight and density was cut out from the absorbent article, and the weight of the cut out part was measured. Next, portions other than the absorbent body such as the front sheet and the back sheet are removed from the cut out portion, and the weight of the absorbent body is measured. The basis weight was calculated from the weight of the absorbent body and the area of the portion where the basis weight and density were measured. Calculate density based on basis weight and thickness.
又，本說明書中的「長度」的測量，是藉由以下的測量方法所進行者。 The "length" measurement in this specification is performed by the following measurement method.
當吸收性物品1被封入在包裝件等的時候，使用從包裝件取出，並在這樣的狀態下在20℃±2℃、相對濕度60%±5%RH的環境下放置12小時後的樣本。 When the absorbent article 1 is enclosed in a package or the like, use the sample taken out from the package and left in such a state in an environment of 20 ° C ± 2 ° C and relative humidity 60% ± 5% RH for 12 hours. .
接著，使用親和測定株式會社製的彈簧量尺(帶子：被覆加入玻璃纖維的聚氯乙烯)，讓其沿著測量對象部位，測量測量對象部位的此狀態的長度。於此，對於10個樣本，在各樣本的狀態下進行上述的測量，並以其平均值作為長度。 Next, a spring scale (tape: polyvinyl chloride coated with glass fiber) made by Affinity Measurement Co., Ltd. was used to measure the length of the measurement target portion in this state along the measurement target portion. Here, for the ten samples, the above-mentioned measurement is performed in the state of each sample, and the average value is taken as the length.
吸收性物品1，是因為具有從吸收性物品1的肌膚對置面側可視認的曲部(前後縫隙42)，所以裝設者可藉由該曲部確認是否有適當安裝後側域。例如吸收性物品1的前後方向L相對於內褲的前後方向L彎曲時，前後縫隙42的延伸方向不會沿著內褲的前後方向。因此，裝設者，可掌握沒有適當安裝後側域S2的情況。 The absorbent article 1 has a curved portion (front and rear slit 42) visible from the skin facing surface side of the absorbent article 1, so the installer can confirm whether the rear side region is properly installed through the curved portion. For example, when the back-and-forth direction L of the absorbent article 1 is curved with respect to the back-and-forth direction L of the underwear, the extending direction of the front-back slit 42 does not follow the front-back direction of the underwear. Therefore, the installer can grasp the situation where the rear side domain S2 is not properly installed.
又，依裝設者，在安裝後側域的前後方向的長度比較長的吸收性物品的時候，將吸收性物品1安裝在內褲，拉起內褲(穿著內褲)後，不能視認吸收性物品1本身，而將手從臀部側***到內褲內，來調整吸收性物品1的寬邊方向的中心位置。如此，在安裝後調整吸收性物品1的位置的話，會有卡著內褲與吸收性物品的黏著區域偏移、或黏著區域彼此黏在一起，而在吸收性物品1無意識地產生皺紋的情況。 In addition, according to the installer, when the absorbent article having a relatively long length in the front-rear direction of the rear side region is installed, the absorbent article 1 is installed in underwear, and the absorbent article 1 cannot be recognized after pulling up the underwear (wearing underwear). By itself, the hand is inserted into the underwear from the hip side to adjust the center position in the widthwise direction of the absorbent article 1. As described above, if the position of the absorbent article 1 is adjusted after mounting, there may be cases where the adhesion region between the panty and the absorbent article is shifted, or the adhesion regions stick to each other, and wrinkles may be generated in the absorbent article 1 unintentionally.
亦即，裝設者在沒有適當地安裝後側域S2的時候，可能會有僅將後側域S2從內褲卸下，再次進行安裝的的情形。此時，因為曲部沿著前後方向延伸，所以，裝設者既可確認曲部的延伸方向，且接觸曲部的狀態下，可將後側域S2再次安裝到適當的位置。裝設者，是可將吸收性物品的寬邊方向的中心配置在身體的寬邊方向的中心地進行安裝，而可抑制在吸收性物品1無意圖地產生皺紋，且減低對於洩漏的不安感。 That is, when the installer does not properly install the rear side domain S2, there may be a case where the rear side domain S2 is only removed from the underpants and the installation may be performed again. At this time, since the curved portion extends in the front-rear direction, the installer can confirm the extending direction of the curved portion and contact the curved portion, and can reattach the rear domain S2 to an appropriate position. The installer can place the center of the absorbent article in the direction of the broad side in the center of the body in the direction of the wide side of the body, and can suppress unintentional wrinkles in the absorbent article 1 and reduce the uneasiness of leakage. .
除此之外，因為曲部為在前後方向連續的前後縫隙，所以，裝設者即使藉由觸感也容易掌握曲部的位置。以裝設者容易掌握曲部的構造來說，不是非連續的點狀，而是連續的線狀為理想。又，以裝設者容易掌握的曲部的構造來說，是縫隙、低基重部及壓花等周圍的吸收芯與厚度、硬度不同的構造為理想。 In addition, since the curved portion is a forward-backward slit that is continuous in the front-rear direction, the installer can easily grasp the position of the curved portion even by the touch. For the installer to easily grasp the structure of the curved part, it is not a discontinuous point shape, but a continuous line shape is ideal. In addition, the structure of the curved portion that is easy for the installer to grasp is preferably a structure having different thicknesses and hardnesses around the absorbent core such as the gap, the low basis weight portion, and the embossing.
圖5，是吸收性物品1被裝用者安裝的狀態的剖視圖。圖5(a)，是沿著***口抵接域S1中的寬邊方向的剖視圖，圖5(b)，是沿著後側域S2中的寬邊方向的剖視圖。圖5(a)，是以圖1的C-C剖面作為基準，圖5(b)，是圖1的D-D剖面作為基準。圖5中，用二點鏈線表示裝用者的身體的線條。裝用作為生理用衛生棉的吸收性物品1的時候，將吸收性物品卡著在內褲S，將該內褲拉起進行穿用。一般的生理用衛生棉的吸收芯的寬邊方向的尺寸，是被設計的比裝用者的胯間的寬邊方向的尺寸更寬。因為，被裝用的狀態的吸收性物品1的***口抵接域S1，是因為被裝設者的兩腿夾著，而承受從寬邊方向的外側朝向寬邊方向的內側的力。 FIG. 5 is a cross-sectional view of a state where the absorbent article 1 is mounted by a user. FIG. 5 (a) is a cross-sectional view taken along the wide side direction in the excretion port abutment area S1, and FIG. 5 (b) is a cross-sectional view taken along the wide side direction in the rear side area S2. Fig. 5 (a) is based on the C-C section of Fig. 1 as a reference, and Fig. 5 (b) is a D-D section of Fig. 1 as a reference. In FIG. 5, the line of the wearer's body is indicated by a two-dot chain line. When the absorbent article 1 used as a sanitary napkin is mounted, the absorbent article is caught in the underpants S, and the underpants are pulled up and worn. The width dimension of the absorbent core of a general sanitary napkin is designed to be wider than the dimension of the width direction of a user's crotch. This is because the excretory opening of the absorbent article 1 in the installed state abuts the area S1 because it is sandwiched between the legs of the installer and receives a force from the outside in the wide side direction toward the inside in the wide side direction.
沿著吸收芯31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，沿著裝用者的***的陰裂(經血出來的***口附近)附近的寬邊方向的身體的剖面形狀，是大***比大腿的根部更突出，且是朝吸收性物品側突出的凸形狀。在該裝用者的***域，吸收性物品的***口抵接域S1對置被配置。吸收 性物品1，是被安裝在內褲S，且被裝用在裝用者的狀態下，***口抵接域S1的吸收芯被大***的突出推下，而變形成朝非肌膚對置面側***。在裝用者的***，***口抵接域S1的吸收芯沿著身體被配置，而可抑制***的洩漏。 The cross-sectional shape of the body of the wearer in the widthwise direction W of the absorbent core 31 is different from the vicinity of the hips and the hips. Specifically, the cross-sectional shape of the body along the broad side near the cleft lip of the wearer (near the vaginal opening from the menstrual flow) is that the labia majora protrudes more than the base of the thigh and faces the absorbent article side. Protruding convex shape. In the user's crotch region, the excretory opening of the absorbent article is arranged to face the region S1. absorb The sexual article 1 is installed in the underpants S and is installed in the state of the wearer. The absorbent core of the excretory abutment region S1 is pushed down by the protrusion of the labia majora, and changes to the side facing the non-skin facing surface. Bulge. Under the crotch of the wearer, the excretory port abuts the absorbent core of the region S1 along the body, and the crotch leakage can be suppressed.
又，在比較裝用者的大***位於後方位置的會陰部更位於後方，是肛門、股溝位於此。沿著比該會陰部更後方附近的寬邊方向的身體的剖面形狀，是寬邊方向的中心凹陷的形狀。吸收性物品的後側域S2和該裝用者的臀部對置被配置。例如，夜用的生理用衛生棉，是在仰躺的睡姿下被使用的情況多。洩漏的大部分，是一次排出大量的經血，而來不及吸收***口正下的經血的時候或位在***口正下的吸收體沒有和身體貼合時，經血流入到比臀部凹陷的部分，而使該經血順著身體露出者。在身體的臀部與吸收性物品之間間隙產生的話，尤其在夜用的生理用衛生棉，會有經血順著身體流到背側後方，而從吸收性物品的後面漏出的顧慮。 In addition, the perineal area of the comparative user's labia majora is located further behind, and the anus and groin are located here. The cross-sectional shape of the body along the wide side direction near the rear part of the perineum is a shape in which the center in the wide side direction is recessed. The rear region S2 of the absorbent article is arranged to face the hips of the user. For example, night-use sanitary napkins are often used in a lying position in a supine position. Most of the leakage occurs when a large amount of menstrual blood is discharged at one time, and when it is too late to absorb menstrual blood directly below the vaginal opening, or when the absorbent body located directly below the vaginal opening does not fit the body, the menstrual blood flows into the recessed portion of the hip, Those who exposed the menstrual blood along the body. If there is a gap between the body's buttocks and the absorbent article, particularly in the case of a night-use sanitary napkin, menstrual blood may flow along the body to the back side and leak out from the back of the absorbent article.
本實施的形態的吸收性物品，是在後側域S2藉由左右的臀部推下吸收芯31的側部。因此，在後側域的吸收芯的寬邊方向的側部，是比後側域的吸收芯31的寬邊方向的中央更需要力。藉由左右的臀部推下吸收芯的側部的話，後側域的吸收體的寬邊方向的中央，是以前後縫隙作為頂點朝裝用者側***。因此，後側域S2的吸收芯31的寬邊方向的中央容易被配置在臀部間的凹陷，而 進一步沿著裝用者的臀部配置吸收芯31。其結果，可防止經血等的體液順著身體流到背側後方，從吸收性物品的後面漏出的情況。 The absorbent article according to the embodiment is a side portion of the absorbent core 31 that is pushed down by the left and right hips in the rear region S2. Therefore, a side portion in the widthwise direction of the absorbent core in the rear region requires more force than a center in the widthwise direction of the absorbent core 31 in the rear region. When the sides of the absorbent core are pushed down by the left and right buttocks, the center of the widthwise direction of the absorbent body in the rear side region bulges toward the wearer's side with the front and rear slits as the apex. Therefore, the center of the width direction of the absorbent core 31 of the back side area S2 is easily arrange | positioned in the recess between hips, and The absorbent core 31 is further arranged along the hips of the wearer. As a result, it is possible to prevent body fluid such as menstrual blood from flowing down the back side of the body and leaking out from the back of the absorbent article.
又，後側域S2的吸收芯31的寬邊方向的中央，是形成有前後縫隙42，且實質上沒有配置吸收材料。因此，***的部分，尤其是頂點的厚度變薄。又，在前後縫隙42配置有吸收材料的話，吸收芯31藉由該吸收材料的剛性容易維持平坦的狀態，且會有吸收芯31不易以前後縫隙42為基點彎折。可是，在前後縫隙42，因為實質上沒有配置吸收材料，所以吸收芯31容易維持以該前後縫隙42為基點彎折的狀態。因此，可使吸收性物品1更緊貼裝用者的臀部間的間隙地配置，可抑制臀部中的洩漏。 In the center of the widthwise direction of the absorbent core 31 in the rear side region S2, front and rear slits 42 are formed, and substantially no absorbent material is arranged. Therefore, the thickness of the raised portion, especially the apex, becomes thin. When an absorbent material is arranged in the front and rear slits 42, the absorbent core 31 is easily maintained in a flat state due to the rigidity of the absorbent material, and the absorbent core 31 is difficult to bend in the front and rear slits 42 as a base point. However, since the absorbent material is not substantially arranged in the front and rear slits 42, the absorbent core 31 easily maintains the state of being bent using the front and rear slits 42 as a base point. Therefore, the absorbent article 1 can be arranged closer to the gap between the hips of the user, and leakage in the hips can be suppressed.
裝設者即可掌握被配置在臀部間的間隙的曲部的位置，亦可安裝吸收性物品。因此，藉由將吸收性物品安裝在適當的位置，可實際感受可抑制洩漏的效果，並可抑制對洩漏的不安感。 The installer can grasp the position of the curved portion arranged in the gap between the buttocks, and can attach an absorbent article. Therefore, by installing the absorbent article in an appropriate position, the effect of suppressing the leakage can be felt practically, and the uneasiness about the leakage can be suppressed.
曲部(前後縫隙42)，也可在臀翼4比最位於寬邊方向的外側的最外緣部4E更朝後方延伸。後側域S2的吸收體30，是藉由左右的臀部推下吸收體的側部及臀翼4。後側域的吸收體的寬邊方向的中央，是藉由吸收體的側部及臀翼被推而朝裝用者側***被配置在左右的臀部間的間隙。 The curved portion (front-rear slit 42) may extend further rearwardly in the hip wing 4 than the outermost edge portion 4E located at the outermost side in the wide side direction. The absorber 30 in the rear side region S2 pushes down the sides of the absorber and the hip wing 4 by the left and right hips. The center in the widthwise direction of the absorbent body in the rear region is a gap between the left and right hips which is bulged toward the wearer's side by pushing the sides of the absorbent body and the hip wings.
例如，臀翼4沒有被配置在適當的位置的 話，會有在左右的臀翼4施加的力偏移，使得從後側域S2的吸收體30的寬邊方向的中央偏移的位置朝穿用者側***的顧慮。尤其，在臀翼4最位在寬邊方向的外側的最外緣部，是裝用者的臀部的力施加容易。曲部(前後縫隙42)，因為在臀翼4比最位於寬邊方向的外側的最外緣部4E更朝後方延伸，所以，在前後方向可將***口抵接域S1到最外緣部4E的區域安裝在適當的位置。在左右的臀翼4大致均等地施力，容易使後側域S2的吸收體30的寬邊方向的中央朝裝用者側***。 For example, hip wing 4 is not configured in the proper position. Then, there is a concern that the force applied to the left and right hip wings 4 is shifted so that the position shifted from the center in the widthwise direction of the absorbent body 30 in the rear side region S2 is raised toward the wearer side. In particular, the outermost edge portion of the hip wing 4 that is most outward in the wide side direction is easy to apply the force of the buttocks of the wearer. The curved portion (front and rear slit 42) extends rearwardly at the hip flap 4 than the outermost edge portion 4E, which is located at the outermost side in the wide side direction, so that the excretory opening can abut the region S1 to the outermost edge portion in the front-rear direction. The 4E area is installed in place. When the left and right hip wings 4 are applied approximately evenly, it is easy to bulge the center of the absorber 30 in the rear region S2 in the width direction toward the wearer's side.
曲部(前後縫隙42)也可被配置在吸收性物品的寬邊方向的中心。可讓吸收性物品的寬邊方向的中心朝裝用者側***，可讓該***部分的頂點貼合在左右的臀部的間隙。 The curved portion (front-back slit 42) may be arranged at the center in the widthwise direction of the absorbent article. The center of the absorbent article in the width direction can be raised toward the wearer's side, and the apex of the raised portion can be fitted to the gap between the left and right buttocks.
後側域S2的吸收芯31，也可具有和曲部(前後縫隙42)相連，且從曲部朝寬邊方向W的外側延伸的輔助曲部(輔助縫隙43)。輔助曲部，是從寬幅方向的外側愈朝向寬邊方向的內側愈朝後側延伸。又，在其輔助曲部的寬邊方向之間，是形成有朝前後方向延伸的曲部。可表示藉由曲部與輔助曲部朝向後方延伸的箭頭印。對於裝設者可認識裝設時動手的方向，可促進適當的安裝操作。 The absorbent core 31 of the rear side region S2 may have an auxiliary curved portion (auxiliary slit 43) connected to the curved portion (front-back slit 42) and extending from the curved portion toward the outside in the widthwise direction W. The auxiliary curved portion extends from the outer side in the width direction to the inner side in the wide side direction toward the rear side. A curved portion extending in the front-rear direction is formed between the widthwise directions of the auxiliary curved portions. It can be shown by the arrow mark extending backward with the curved portion and the auxiliary curved portion. The installer can recognize the direction of the hands during installation, which can promote proper installation operations.
又，因為輔助縫隙43與前後縫隙42交叉被配置，所以，裝用者可經由輔助縫隙43及前後縫隙42掌握吸收性物品的寬邊方向的中央的位置。因此，在裝用吸收性物品後，沒有視認吸收性物品1本身，而將手從臀部 側***到內褲內，來調整吸收性物品1的寬邊方向的中心位置時，可掌握吸收性物品的寬邊方向的中央的位置，並可容易進行調整。 In addition, since the auxiliary slit 43 and the front-rear slit 42 are arranged so as to intersect, the wearer can grasp the center position in the widthwise direction of the absorbent article via the auxiliary slit 43 and the front-rear slit 42. Therefore, after the absorbent article is installed, the hands are not seen from the absorbent article 1 When the side is inserted into the panties to adjust the center position in the widthwise direction of the absorbent article 1, the center position in the widthwise direction of the absorbent article can be grasped, and the adjustment can be easily performed.
曲部(前後縫隙42)及從曲部朝後方延伸的區域，在厚度方向也可沒有重疊在黏著區域60。藉由曲部在厚度方向沒有重疊在黏著區域，容易抑制因內褲過度阻礙曲部的變形的情況，且容易以曲部為基點變形。又，吸收性物品1的後側域S2沒有適當地被安裝而再次安裝S2的時候，裝設者，是拿著作為印記的曲部的附近修正後側域S2的安裝。具體而言，裝設者，可能會拿著從曲部延伸到後方的區域從內褲剝下後側域S2，再次將後側域S2安裝到內褲。或依裝設者，將吸收性物品1安裝在內褲，拉起內褲(穿著內褲)後，不視認吸收性物品1本身，而將手從臀部側***到內褲內，來調整吸收性物品1的寬邊方向的中心位置。如此，在安裝後調整吸收性物品1的位置的時候，因為在從曲部朝後方延伸的區域沒有設置黏著區域60，所以可防止黏著區域60黏在裝用者的手，而可提昇裝設時的操作性。 The curved portion (front-rear slit 42) and the area extending rearward from the curved portion may not overlap the adhesion area 60 in the thickness direction. Since the curved portion does not overlap in the adhesion area in the thickness direction, it is easy to suppress the situation that the underwear is excessively hindered from deforming the curved portion, and it is easy to deform with the curved portion as a base point. In addition, when the rear side area S2 of the absorbent article 1 is not properly installed and S2 is reinstalled, the installer corrects the installation of the rear side area S2 with the writing as the vicinity of the curved portion. Specifically, the installer may peel the rear side region S2 from the panties while holding the area extending from the curved portion to the rear, and install the rear side region S2 to the panties again. Or according to the installer, install the absorbent article 1 in underwear, pull up the underwear (wearing underwear), and ignore the absorbent article 1 by itself, and insert your hand from the hip side into the underwear to adjust the absorbent article The center position in the wide direction. In this way, when the position of the absorbent article 1 is adjusted after installation, since the adhesion area 60 is not provided in the area extending rearward from the curved portion, the adhesion area 60 can be prevented from sticking to the user's hand, and the installation can be improved Time operability.
在前後縫隙42的前部的寬邊方向的兩外側，也可設有可視認非肌膚面薄片20的識別部70。裝設者，是經由構成曲部的前後縫隙42視認非肌膚面薄片20，而可容易掌握吸收性物品1的前後方向L。 Recognition portions 70 of the non-skin surface sheet 20 may be provided on both outer sides of the front side of the front and rear slits 42 in the widthwise direction. The installer can visually recognize the non-skin surface sheet 20 through the front and rear slits 42 constituting the curved portion, and can easily grasp the front-back direction L of the absorbent article 1.
又，因為在曲部(前後縫隙42)的寬邊方向的外側設有識別部70，所以裝設者經由曲部(前後縫隙42) 與識別部70可更適當地掌握吸收性物品1的前後方向L。又，因為在曲部的左側與曲部的右側分別設有識別部70，所以，裝設者不僅能掌握吸收性物品1的前後方向L的偏移，同時也能容易掌握左右的位置偏移。 In addition, since the identification portion 70 is provided on the outer side in the width direction of the curved portion (front-rear slit 42), the installer passes the curved portion (front-rear slit 42). The identification unit 70 can more appropriately grasp the front-back direction L of the absorbent article 1.
