[Effect of the invention]

若依據本發明，能夠提供在使吸收性芯材的腹部側使貼身性提升之短褲型吸收性物品。According to the present invention, it is possible to provide a pants-type absorbent article which improves the fit of the abdomen side of the absorbent core member.

依據本說明書及添附圖式的記載，至少可使以下的事項更明確。
一種短褲型吸收性物品，係具有相互地交叉的上下方向、左右方向及前後方向，並具備有、吸收性本體，其具備沿著前述上下方向配置之吸收性芯材，在前述上下方向的下端部朝前後折彎；及接合於前述吸收性本體的前側上端部，並具有朝前述左右方向伸縮之前側伸縮區域的前側皮帶部，其特徵為，前述吸收性芯材係具有朝前述前後方向的前側折彎之部分亦即前側部，前述吸收性芯材係在前述前側部，具有從前述上下方向的上側朝下側且從前述左右方向的外側朝中心側傾斜，並且基重較周圍的區域低之一對傾斜低基重區域，前述一對傾斜低基重區域全體係與前述前側伸縮區域重複。According to the description of the specification and the accompanying drawings, at least the following matters can be made clear.
A pants-type absorbent article having an absorbent body that has an absorbent core disposed along the vertical direction and has a lower end in the up-down direction And a front side belt portion joined to the front upper end portion of the absorbent body and having a front side expansion and contraction region extending in the left-right direction, wherein the absorbent core member has a front-rear direction The front side portion, that is, the front side portion, the absorbent core member has the front side portion, and has an area which is inclined from the upper side in the up-and-down direction toward the lower side and is inclined toward the center side from the outer side in the left-right direction, and has a base weight. One of the lower pair of inclined low basis weight regions, the pair of inclined low basis weight regions are overlapped with the aforementioned front side expansion and contraction regions.

若依據這樣的短褲型吸收性物品，藉由以從穿用者的恥骨沿著***部的方式傾斜配置之一對傾斜低基重區域，使得吸收性芯材可追隨穿用者的腳而自由地變形。又，藉由左右方向的伸縮力從吸收性芯材的非肌膚側作用，使得在穿用紙尿布時，吸收性芯材按壓於穿用者的下腹部。因此，可使穿用者的恥骨附近之吸收性本體的貼身性提升。According to such a pants-type absorbent article, the inclined core material can be freely followed by the wearer's foot by tilting one of the pair of pubic bones from the wearer along the crotch portion to the inclined low basis weight region. Ground deformation. Further, the elastic force in the right and left direction acts from the non-skin side of the absorbent core material, so that when the disposable diaper is worn, the absorbent core member is pressed against the lower abdomen of the wearer. Therefore, the fit of the absorbent body near the pubis of the wearer can be improved.

如該短褲型吸收性物品，其中期望在前述前側部，於前述一對傾斜低基重區域的前述左右方向之間，設有沿著前述上下方向將前述吸收性芯材貫通之中央低基重區域。In the pants type absorbent article, it is preferable that a center-low basis weight that penetrates the absorbent core material along the vertical direction is provided between the left and right directions of the pair of inclined low basis weight regions in the front side portion. region.

若依據這樣的短褲型吸收性物品，當吸收性芯材在穿用者的***部被雙腳挾持時，以剛性最低的中央低基重區域為基點，吸收性芯材沿著上下方向容易折彎變形為朝肌膚側形成凸狀。藉此，吸收性芯材容易沿著穿用者的***口吻合。According to such a pants-type absorbent article, when the absorbent core material is held by both feet in the lower part of the wearer's crotch, the absorbent core material is easily folded in the up and down direction with the lowest central low basis weight region as the base point. The bending deformation is convex toward the skin side. Thereby, the absorbent core material is easily fitted along the wearer's excretory opening.

如該短褲型吸收性物品，其中期望前述中央低基重區域的短邊方向之寬度係較前述一對傾斜低基重區域的各自的短邊方向之寬度廣。In the pants type absorbent article, it is preferable that a width in a short side direction of the central low basis weight region is wider than a width in a short side direction of each of the pair of inclined low basis weight regions.

若依據這樣的短褲型吸收性物品，由於中央低基重區域的剛性較傾斜低基重區域小，更容易產生折彎變形，故，藉由吸收性芯材夾入於穿用者的腹股溝，使得中央低基重區域的區域最先被折彎，接著傾斜低基重區域形成為折彎變形的起點，藉此，吸收性芯材可容易沿著穿用者的身體形狀自然地變形。According to such a pants-type absorbent article, since the rigidity of the central low basis weight region is smaller than that of the inclined low basis weight region, the bending deformation is more likely to occur, so that the absorbent core member is sandwiched between the wearer's groin. The region of the central low basis weight region is first bent, and then the inclined low basis weight region is formed as the starting point of the bending deformation, whereby the absorbent core material can be easily deformed naturally along the shape of the wearer's body.

如該短褲型吸收性物品，其中期望在前述上下方向，前述一對傾斜低基重區域的下端之位置係較前述中央低基重區域的下端之位置高。In the pants type absorbent article, it is preferable that a position of a lower end of the pair of inclined low basis weight regions is higher than a position of a lower end of the central low basis weight region in the vertical direction.

若依據這樣的短褲型吸收性物品，藉由中央低基重區域設置成接近穿用者的褲襠部之高度，使得吸收性芯材變得容易坐為用來進行凸變形之折彎誘導區域發揮功能。另外，藉由一對傾斜低基重區域設成穿用者的恥骨附近之高度，可因應穿用者的腳的動作，使吸收性芯材容易自由地變形。According to such a pants-type absorbent article, the central low-weight region is provided close to the height of the wearer's crotch portion, so that the absorbent core material can be easily seated as a bending-inducing region for performing convex deformation. Features. Further, by providing a pair of inclined low basis weight regions to the height of the wearer's pubic bone, the absorbent core member can be easily deformed freely in response to the action of the wearer's foot.

如該短褲型吸收性物品，其中期望在前述上下方向，前述一對傾斜低基重區域的上端之位置係較前述中央低基重區域的上端之位置高。In the pants type absorbent article, it is preferable that a position of an upper end of the pair of inclined low basis weight regions is higher than a position of an upper end of the center low basis weight region in the vertical direction.

若依據這樣的短褲型吸收性物品，中央低基重區域的位置不會變得過高，在穿用者的腹部之成為平面狀的區域，不易使吸收性芯材進行凸變形。另外，藉由將傾斜低基重區域設置到較中央低基重區域更高的位置，容易追隨穿用者的腳之動作，直到吸收性芯材的上方可容易產生折彎變形。According to such a pants-type absorbent article, the position of the center low basis weight region does not become excessively high, and the absorbent core member is less likely to be convexly deformed in a flat region of the wearer's abdomen. Further, by setting the inclined low basis weight region to a position higher than the central low basis weight region, it is easy to follow the action of the wearer's foot until the upper portion of the absorbent core material is easily deformed.

如該短褲型吸收性物品，其中期望還具有接合於前述吸收性本體的後側上端部並具備朝前述左右方向伸縮的後側伸縮區域之後側皮帶部，在前述左右方向，具有將前述前側皮帶部的兩端部與前述後側皮帶部的兩端部接合之端部接合區域，前述前側皮帶部的下端緣係具有從前述端部接合區域的下端朝褲襠部斜向傾斜之傾斜部。In the pants-type absorbent article, it is preferable to further include a rear side belt portion that is joined to the rear upper end portion of the absorbent body and that has a rear side expansion and contraction region that expands and contracts in the left-right direction, and has the front side belt in the left-right direction. An end portion joining portion where both end portions of the portion are joined to both end portions of the rear side belt portion, and a lower end edge of the front side belt portion has an inclined portion that is inclined obliquely from the lower end of the end portion joining region toward the crotch portion.

若依據這樣的短褲型吸收性物品，當穿用紙尿布時，若將前後的皮帶部朝左右方向的兩側拉引的話，傾斜部也會朝左右方向的外側被拉引，因此，經由該傾斜部，吸收性本體變得容易朝斜上側被拉引。藉此，吸收性本體變得不易從穿用者的恥骨周邊偏移，使得貼身性提升。According to such a pants-type absorbent article, when the front and rear belt portions are pulled toward the both sides in the left-right direction when the disposable diaper is worn, the inclined portion is also pulled outward in the left-right direction, and therefore, the inclination is caused by the inclination. The absorbent body becomes easy to be pulled toward the upper side. Thereby, the absorbent body becomes less likely to be displaced from the wearer's pubic periphery, so that the fit is improved.

如該短褲型吸收性物品，其中期望前述傾斜部與前述上下方向所形成的角度中之較小的角度係較前述傾斜低基重區域與前述上下方向所形成的角度中較小之角度更大。In the pants type absorbent article, it is preferable that a smaller angle among the angles formed by the inclined portion and the up-and-down direction is larger than a smaller angle among the angles formed by the inclined low basis weight region and the up-and-down direction. .

若依據這樣的短褲型吸收性物品，由於吸收性本體變得容易朝左右方向拉引，故，對於沿著傾斜低基重區域折彎變形之吸收性芯材，左右方向之伸縮性變得容易作用。因此，吸收性芯材變得容易容易按壓於穿用者的肌膚，故可使貼身性提升。According to such a pants-type absorbent article, since the absorbent body is easily pulled in the left-right direction, the stretchability of the absorbent core material which is bent and deformed along the inclined low basis weight region is easy. effect. Therefore, the absorbent core material is easily pressed against the wearer's skin, so that the fit can be improved.

如該短褲型吸收性物品，其中期望還具有沿著前述傾斜部伸縮之腳圍彈性構件，產生藉由前述腳圍彈性構件之伸縮性的區域與前述吸收性芯材係未重複。In the pants-type absorbent article, it is desirable to further have a foot-surrounding elastic member that expands and contracts along the inclined portion, and a region where the stretchability of the foot-elastic member is generated is not overlapped with the absorbent core member.

若依據這樣的短褲型吸收性物品，當將吸收性本體朝斜上方拉起時，多餘的力不易作用於吸收性芯材本身，變得不易阻礙吸收性芯材的折彎變形。According to such a pants-type absorbent article, when the absorbent body is pulled up obliquely upward, the excess force does not easily act on the absorbent core itself, and it becomes difficult to hinder the bending deformation of the absorbent core.

如該短褲型吸收性物品，其中期望前述吸收性芯材係在前述前側部具有前述左右方向的寬度變窄之縮徑部，前述縮徑部中之前述左右方向上的寬度最窄之部分係與前述前側伸縮區域重複。In the pants-type absorbent article, it is preferable that the absorbent core member has a reduced diameter portion in which the width in the left-right direction is narrowed in the front side portion, and a portion in the left-right direction of the reduced-diameter portion is the narrowest portion. It is repeated with the aforementioned front side expansion and contraction area.

若依據這樣的短褲型吸收性物品，藉由在吸收性芯材的縮徑部，對左右方向的寬度變得最窄之且容易變形之部分，前側伸縮區域之左右方向的伸縮性產生作用，使得已經變形的吸收性芯材按壓於穿用者的肌膚側，變得容易密接。因此，既可因應身體形狀使吸收性芯材正確地變形，亦可使貼身性提升。According to such a pants-type absorbent article, the stretchable portion of the absorbent core member has a narrowest width in the left-right direction and is easily deformed, and the stretchability of the front-side stretchable region in the left-right direction acts. The deformed core material that has been deformed is pressed against the skin side of the wearer, and is easily adhered. Therefore, the absorbent core can be properly deformed in accordance with the shape of the body, and the fit can be improved.

如該短褲型吸收性物品，其中期望在前述前側部，於前述一對傾斜低基重區域的前述左右方向之間，設有沿著前述上下方向將前述吸收性芯材貫通之中央低基重區域，在前述上下方向上，前述縮徑部中之前述左右方向上的寬度最窄之部分的位置係較前述中央低基重區域的下端的位置高。In the pants type absorbent article, it is preferable that a center-low basis weight that penetrates the absorbent core material along the vertical direction is provided between the left and right directions of the pair of inclined low basis weight regions in the front side portion. In the vertical direction, the position of the portion of the reduced diameter portion that is the narrowest in the left-right direction is higher than the position of the lower end of the central low-basic region.

若依據這樣的短褲型吸收性物品，在吸收性芯材的縮徑部，於左右方向上的寬度最窄且容易變形之部分，使吸收性芯材沿著上下方向凸變形之力、和配合穿用者的身體而使吸收性芯材從褲襠部朝下腹部立起變形之力不易相互干涉。藉此，使得吸收性芯材可正確地變形。According to such a pants-type absorbent article, the force of the absorbent core material being convexly deformed in the vertical direction in the portion of the reduced diameter portion of the absorbent core material that is the narrowest in the left-right direction and easily deformed, and the fit The force of the wearer's body to cause the absorbent core material to stand up from the crotch portion to the lower abdomen does not easily interfere with each other. Thereby, the absorbent core material can be properly deformed.

如該短褲型吸收性物品，其中期望前述一對傾斜低基重區域係具有：一對第1傾斜低基重區域；及設在前述一對第1傾斜低基重區域的前述左右方向上的內側之區域的一對第2傾斜低基重區域。In the pants type absorbent article, it is preferable that the pair of inclined low basis weight regions have: a pair of first inclined low basis weight regions; and the pair of first inclined low basis weight regions in the left-right direction A pair of second inclined low basis weight regions in the inner region.

若依據這樣的短褲型吸收性物品，除了設有1對第1傾斜低基重區域以外，還設置1對第2傾斜低基重區域，藉此，使得讓吸收性芯材變形時的折彎起點增加，使得吸收性芯材變得能夠更圓滑地變形。According to such a pants-type absorbent article, in addition to the pair of first inclined low basis weight regions, one pair of second inclined low basis weight regions are provided, thereby making the bending of the absorbent core material deformed. The starting point is increased, so that the absorbent core material becomes able to deform more smoothly.

如該短褲型吸收性物品，其中期望前述一對第2傾斜低基重區域的長度方向上之長度係較前述一對第1傾斜低基重區域的長度方向上之長度短。In the pants type absorbent article, it is preferable that a length of the pair of second inclined low basis weight regions in the longitudinal direction is shorter than a length of the pair of first inclined low basis weight regions in the longitudinal direction.

若依據這樣的短褲型吸收性物品，在左右方向的內側之第2傾斜低基重區域，吸收性芯材之折彎變形變小，在左右方向的外側之第1傾斜低基重區域，吸收性芯材的折彎變形變大。因此，吸收性芯材係在接近穿用者的腳之左右方向的外側之區域，容易大幅度變形而容易追隨腳的動作。According to such a pants-type absorbent article, the bending deformation of the absorbent core material is reduced in the second inclined low basis weight region on the inner side in the left-right direction, and is absorbed in the first inclined low basis weight region on the outer side in the left-right direction. The bending deformation of the core material becomes large. Therefore, the absorbent core material is likely to be greatly deformed in a region close to the outer side in the left-right direction of the wearer's foot, and it is easy to follow the movement of the foot.

如該短褲型吸收性物品，其中期望在前述上下方向，前述一對第2傾斜低基重區域的下端之位置係較前述一對第1傾斜低基重區域的下端之位置高。In the pants type absorbent article, it is preferable that a position of a lower end of the pair of second inclined low basis weight regions is higher than a position of a lower end of the pair of first inclined low basis weight regions in the vertical direction.

若依據這樣的短褲型吸收性物品，藉由使左右方向的外側之傾斜低基重區域延伸至上下方向之盡可能低的位置，使得即使在接近穿用者的腹股溝之區域，吸收性芯材也變得容易折彎變形，可更容易追隨穿用者的腳之動作。According to such a pants-type absorbent article, the inclined core material in the left-right direction is extended to a position as low as possible in the up-and-down direction, so that the absorbent core material is in a region close to the groin of the wearer. It also becomes easy to bend and deform, making it easier to follow the wearer's foot movements.

如該短褲型吸收性物品，其中期望前述吸收性芯材係在前述前側部具有沿著前述上下方向，基重變得較周圍的區域低之第1上側低基重區域；及沿著前述上下方向，基重變得較周圍的區域低之第1下側低基重區域，前述第1上側低基重區域的下端與前述第1傾斜低基重區域的上端連接，前述第1傾斜低基重區域的下端與前述第1下側低基重區域的上端連接。In the pants type absorbent article, it is preferable that the absorbent core member has a first upper low basis weight region having a lower basis weight in a region along the vertical direction and a lower base region in the front side portion; and a first lower low basis weight region in which the basis weight is lower than the surrounding area, and a lower end of the first upper low basis weight region is connected to an upper end of the first inclined low basis weight region, and the first inclined low base The lower end of the heavy region is connected to the upper end of the first lower low basis weight region.

In the following, as an example of the [pants-type absorbent article] of the present invention, a disposable disposable diaper 1 (hereinafter also referred to as [diaper 1]) will be described as an example. However, the pants-type absorbent article of the present invention can be used, for example, as a disposable disposable diaper for children, a physiological product (short-type sanitary napkin), or the like.

<<The whole structure of the disposable diaper 1>>
Fig. 1 is a schematic perspective view of the paper diaper 1. Fig. 2 is a schematic plan view of the disposable diaper 1 viewed from the non-skin side and in an expanded state. Fig. 3 is a schematic sectional view taken along line II of Fig. 2; In addition, the [elongated state] of the disposable diaper 1 is a state in which the disposable diaper 1 is stretched to be wrinkle free, and the dimensions of the members constituting the disposable diaper 1 (for example, the exterior member 20 to be described later) are elongated until the member is A state in which the size of the body is uniform or close to the size.

紙尿布1係具有相互地交叉的上下方向、左右方向及前後方向，並且如圖3所示，具有層積了各構件之厚度方向。在上下方向中，將成為穿用者的腰圍側之側設定為上側、將成為穿用者的褲襠之側設定為下側。在前後方向中，將成為穿用者的腹部側之側設定為前側、將成為穿用者的背部側之側設定為後側。在厚度方向，將抵接於穿用者的身體之側稱為肌膚側，將其相反側稱為非肌膚側。另外，在圖2的展開狀態，紙尿布1係具有相互交叉的長度方向及寬度方向。長度方向係沿著上下方向之方向，寬度方向係與左右方向相同之方向。The disposable diaper 1 has an up-and-down direction, a left-right direction, and a front-back direction which mutually cross, and has the thickness direction which laminated each member as shown in FIG. In the up-and-down direction, the side to be the wearer's waist side is set to the upper side, and the side to be the wearer's crotch is set to the lower side. In the front-rear direction, the side to be the abdomen side of the wearer is set to the front side, and the side to be the back side of the wearer is set to the rear side. In the thickness direction, the side that abuts the wearer's body is referred to as the skin side, and the opposite side is referred to as the non-skin side. Further, in the unfolded state of Fig. 2, the disposable diaper 1 has a longitudinal direction and a width direction which intersect each other. The longitudinal direction is in the direction of the up and down direction, and the width direction is the same direction as the left and right direction.

紙尿布1係具有平面視角為長方形狀之吸收性本體10；及位於吸收性本體10的非肌膚側之外裝構件20。外裝構件20係具有：位於圖1的前後方向上之前側的腹部側外裝構件21(前側皮帶部21)；位於前後方向上之後側的背部側外裝構件22(後側皮帶部22)；及將該等構件連結之褲襠外裝構件23(褲襠構件23)。在厚度方向上相鄰接的前述構件係以接著劑等接合。The disposable diaper 1 has an absorbent body 10 having a rectangular viewing angle; and a non-skin side outer member 20 of the absorbent body 10. The exterior member 20 has the abdominal side exterior member 21 (front side belt portion 21) on the front side in the front-rear direction of FIG. 1, and the back side exterior member 22 (rear side belt portion 22) on the rear side in the front-rear direction. And the crotch exterior member 23 (the crotch member 23) to which the members are attached. The aforementioned members adjacent in the thickness direction are joined by an adhesive or the like.

又，前側皮帶部21位於吸收性本體10的長度方向之一端側，後側皮帶部22位於吸收性本體10的長度方向之另一端側。在吸收性本體10的長度方向，將前側皮帶部21存在之側設為前側、將後側皮帶部22存在之側設為後側。亦即，前側皮帶部21係位於吸收性本體10之前側上端部，後側皮帶部22係位於吸收性本體10之後側上端部。又，褲襠構件23係較前側皮帶部21及後側皮帶部22位於更靠近肌膚側。Further, the front side belt portion 21 is located on one end side in the longitudinal direction of the absorbent body 10, and the rear side belt portion 22 is located on the other end side in the longitudinal direction of the absorbent body 10. In the longitudinal direction of the absorbent body 10, the side where the front side belt portion 21 exists is referred to as the front side, and the side where the rear side belt portion 22 exists is referred to as the rear side. That is, the front side belt portion 21 is located at the front side upper end portion of the absorbent body 10, and the rear side belt portion 22 is located at the rear side upper end portion of the absorbent body 10. Further, the crotch member 23 is located closer to the skin side than the front side belt portion 21 and the rear side belt portion 22.

再者，在本實施形態的紙尿布1，外裝構件20是由3個構件所構成，但不限於此。例如，前側皮帶部21、後側皮帶部22及褲襠構件23亦可為1個構件。又，亦可為不具有褲襠構件23之結構、在較外裝構件20更靠近非肌膚側進一步層積有與外裝構件20不同之構件的結構。Further, in the disposable diaper 1 of the present embodiment, the exterior member 20 is composed of three members, but the invention is not limited thereto. For example, the front side belt portion 21, the rear side belt portion 22, and the crotch member 23 may be one member. Moreover, it is also possible to have a structure in which the crotch member 23 is not provided, and a member different from the exterior member 20 is further laminated on the side of the outer member 20 closer to the non-skin side.

如圖2所示的展開狀態之紙尿布1，吸收性本體10是在長度方向的預定位置CL對折，將前側皮帶部21的左右方向之兩側部與後側皮帶部22的左右方向之兩側部以熔接等加以接合，藉此形成為如圖1所示的短褲型。亦即，吸收性本體10的長度方向係沿著紙尿布1的上下方向，前側皮帶部21與後側皮帶部22相連結成環狀，形成腰圍開口1a及一對腳圍開口1b。以下，將前側皮帶部21與後側皮帶部22接合後之區域稱為端部接合區域24。In the unfolded state of the disposable diaper 1 shown in FIG. 2, the absorbent main body 10 is folded in a predetermined position CL in the longitudinal direction, and both sides of the front side belt portion 21 in the left-right direction and the left and right directions of the rear side belt portion 22 are folded. The side portions are joined by welding or the like, thereby being formed into a pants type as shown in FIG. In other words, the longitudinal direction of the absorbent body 10 is along the vertical direction of the disposable diaper 1, and the front side belt portion 21 and the rear side belt portion 22 are connected in a ring shape to form a waist opening 1a and a pair of foot opening 1b. Hereinafter, a region where the front side belt portion 21 and the rear side belt portion 22 are joined is referred to as an end portion joining region 24.

又，在本說明書中，將在預定位置CL折彎之吸收性本體10(吸收性芯材11)中之朝前側折彎的部分稱為[前側部10F]、朝後側折彎的部分稱為[後側部10R]。亦即，會有以下的情況，即，在圖2的長度方向，將吸收性本體10(吸收性芯材11)之較預定位置CL更前側的區域稱為[前側部10F]、將較預定位置CL更後側的區域稱為[後側部10R]。In the present specification, the portion of the absorbent body 10 (absorbent core member 11) that is bent at the predetermined position CL, which is bent toward the front side, is referred to as a [front side portion 10F], and a portion that is bent toward the rear side is referred to as a portion that is bent toward the rear side. It is [rear side 10R]. That is, a region in which the absorbent body 10 (absorbent core member 11) is more forward than the predetermined position CL in the longitudinal direction of FIG. 2 is referred to as [front side portion 10F], and will be more predetermined. The area on the rear side of the position CL is referred to as [rear side portion 10R].

吸收性本體10係如圖3所示，具有：吸收性芯材11；位於吸收性芯材11的肌膚側之頂面薄片12；及位於吸收性芯材11的非肌膚側之背面薄片13。圖4A係從肌膚側觀看展開且伸長狀態的吸收性本體10之概略平面圖。圖4B是圖4A的A-A線斷面圖。再者，在圖4B，為了說明的簡單化，未顯示設在吸收性芯材11的低基重區域(後述)。As shown in FIG. 3, the absorbent main body 10 has an absorbent core member 11, a top sheet 12 on the skin side of the absorbent core member 11, and a back sheet 13 on the non-skin side of the absorbent core member 11. Fig. 4A is a schematic plan view of the absorbent body 10 in a developed and stretched state as seen from the skin side. Fig. 4B is a cross-sectional view taken along line A-A of Fig. 4A. In addition, in FIG. 4B, for the simplification of description, the low basis weight region (described later) provided in the absorptive core material 11 is not shown.

吸收性芯材11係為將尿液等的***液吸收並保持之構件，例如藉由混入有高吸收性聚合物(SAP)之紙漿纖維等的吸液性纖維所形成。本實施形態的吸收性芯材11係在長度方向的前側端與後側端之間，具有左右方向上的寬度變窄之縮徑部11c，具有如圖4A所示的平面視角為沙漏時鐘形狀。又，在吸收性芯材11，形成有基重較周圍低之區域亦即各種的低基重區域。關於低基重區域的詳細內容，如後說明。又，吸收性芯材11亦可藉由薄紙、不織布等的透液性薄片加以被覆其外周面。The absorbent core material 11 is a member that absorbs and holds excretion liquid such as urine, and is formed, for example, by a liquid-absorbent fiber such as pulp fibers in which a superabsorbent polymer (SAP) is mixed. The absorptive core material 11 of the present embodiment has a reduced diameter portion 11c having a narrow width in the left-right direction between the front end and the rear end in the longitudinal direction, and has a plan view angle as an hourglass clock shape as shown in FIG. 4A. . Further, in the absorbent core member 11, various low basis weight regions, that is, regions having a lower basis weight than the periphery, are formed. The details of the low basis weight region will be described later. Further, the absorbent core member 11 may be coated with the outer peripheral surface thereof by a liquid permeable sheet such as a tissue or a nonwoven fabric.

頂面薄片12為透液性薄片，例如可使用親水性的熱風不織布、紡黏不織布等。背面薄片13係為不透液性薄片13a及配置於其非肌膚側之疏水性薄片13b的雙層構造。作為不透液性薄片13a，例如可使用樹脂薄膜等，作為疏水性薄片13b，例如可使用具有柔軟性之疏水性不織布等。再者，背面薄片13亦可為不透液性薄片13a之單層構造。The top sheet 12 is a liquid permeable sheet, and for example, a hydrophilic hot air non-woven fabric, a spunbonded nonwoven fabric, or the like can be used. The back sheet 13 is a two-layer structure of the liquid-impermeable sheet 13a and the hydrophobic sheet 13b disposed on the non-skin side. As the liquid-impermeable sheet 13a, for example, a resin film or the like can be used, and as the hydrophobic sheet 13b, for example, a flexible hydrophobic nonwoven fabric or the like can be used. Further, the back sheet 13 may have a single layer structure of the liquid-impermeable sheet 13a.

在背面薄片13的左右方向之兩側，設有側薄片14。此側薄片14係較吸收性芯材11的左右方向的兩端11es、11es更朝左右方向的外側延伸，以吸收性本體10的左右方向的兩端10es、10es作為折返位置，朝左右方向的內側且厚度方向的肌膚側折返，藉此形成1對防漏壁部40。在防漏壁部40，橡膠線等的防漏壁彈性構件41、42是在沿著吸收性本體10的長度方向(上下方向)伸長之狀態下被固定。藉由此防漏壁彈性構件41、42朝長度方向收縮，使得在吸收性本體10的左右方向之兩端部，一對防漏壁部40朝肌膚側立起而作為紙尿布1的防漏壁(腳側皺褶)發揮功能。再者，亦可不設置側薄片14，使背面薄片13(透液性薄片13b)延伸至吸收性芯材11的左右方向之外側，藉此形成防漏壁部40。Side sheets 14 are provided on both sides of the back sheet 13 in the left-right direction. The side sheet 14 extends outward in the left-right direction from both ends 11es and 11es of the absorbent core member 11 in the left-right direction, and the both ends 10es and 10es of the absorbent body 10 in the left-right direction serve as a folding position, and are oriented in the left-right direction. The skin side in the inner side and the thickness direction is folded back, thereby forming a pair of leakage preventing wall portions 40. In the leakage preventing wall portion 40, the leakage preventing wall elastic members 41 and 42 such as rubber threads are fixed in a state of being elongated along the longitudinal direction (vertical direction) of the absorbent body 10. The leakage preventing wall elastic members 41 and 42 are contracted in the longitudinal direction, so that the pair of leakage preventing wall portions 40 are erected toward the skin side at both end portions of the absorbent body 10 in the left-right direction to prevent leakage of the disposable diaper 1. The wall (foot pleats) functions. In addition, the back sheet 14 (liquid permeable sheet 13b) may be extended to the outer side in the left-right direction of the absorbent core member 11 without providing the side sheet 14, thereby forming the leakage preventing wall portion 40.

前側皮帶部21及後側皮帶部22係分別如圖2所示，具有在上下方向上存在有端部接合區域24之腰圍區域211、221；及較腰圍區域211、221更下側的褲襠側區域212、222。腰圍區域211、221係在平面視角呈長方形狀。褲襠側區域212、222係形成為略梯形形狀，其外緣部係具有朝上下方向的下側且朝左右方向的內側傾斜之傾斜部212s、222s。亦即，褲襠側區域212、222之橫寬是朝下側變窄。又，在本實施形態，比起前側皮帶部21之褲襠側區域212，後側皮帶部22的褲襠側區域222較大，可廣泛地被覆穿用者的臀部。As shown in FIG. 2, the front side belt portion 21 and the rear side belt portion 22 respectively have waistline regions 211 and 221 in which the end joint regions 24 are present in the up and down direction, and the crotch side on the lower side of the waist regions 211 and 221, respectively. Areas 212, 222. The waist regions 211 and 221 are rectangular in plan view. The crotch side regions 212 and 222 are formed in a substantially trapezoidal shape, and the outer edge portion has inclined portions 212s and 222s that are inclined to the lower side in the up-and-down direction and to the inner side in the left-right direction. That is, the lateral width of the crotch side regions 212, 222 is narrowed toward the lower side. Further, in the present embodiment, the crotch side region 222 of the rear side belt portion 22 is larger than the crotch side region 212 of the front side belt portion 21, and the wearer's buttocks can be widely covered.

前側皮帶部21及後側皮帶部22分別如圖3所示，具有：位於肌膚側之肌膚側薄片213、223；位於非肌膚側之非肌膚側薄片214、224；及位於該等薄片之間，且至少在紙尿布1的左右方向上具有伸縮性之伸縮性不織布215、225。As shown in FIG. 3, the front side belt portion 21 and the rear side belt portion 22 respectively have skin side sheets 213 and 223 on the skin side, non-skin side sheets 214 and 224 on the non-skin side, and between the sheets. And at least the stretchable nonwoven fabrics 215 and 225 having the stretchability in the left-right direction of the disposable diaper 1.

肌膚側薄片213、223及非肌膚側薄片214、224，理想為柔軟性薄片，例如可使用紡黏不織布、SMS不織布等。The skin side sheets 213 and 223 and the non-skin side sheets 214 and 224 are preferably flexible sheets. For example, a spunbonded nonwoven fabric, an SMS nonwoven fabric, or the like can be used.

伸縮性不織布215、225係為例如具備具有彈性的熱可塑性彈性體性纖維之聚胺甲酸酯系彈性體、和具有非彈性的熱可塑性樹脂性纖維之聚烯烴系樹脂的聚丙烯(PP)，實施有齒輪延伸等的適當的延伸處理之不織布。藉由此延伸處理，將伸縮性不織布215、225作成為在預定的方向上具有伸縮性。再者，延伸處理，可為朝相互正交之方向進行延伸處理者，亦可為僅朝預定方向進行延伸處理者。在僅朝預定方向進行延伸處理之情況，雖會產生預定方向之伸縮性，但，所有的纖維之定向不一定僅沿著預定方向，因此在與預定方向正交之方向亦會產生伸縮性。The stretchable nonwoven fabrics 215 and 225 are, for example, a polyurethane (PP) having a polyurethane elastomer having elastic thermoplastic fibers and a polyolefin resin having inelastic thermoplastic resin fibers. A non-woven fabric having a suitable extension process such as gear extension is implemented. By this stretching process, the stretchable nonwoven fabrics 215 and 225 are made to have stretchability in a predetermined direction. Further, the stretching process may be performed by extending in a direction orthogonal to each other, or may be an extension process only in a predetermined direction. In the case where the stretching treatment is performed only in the predetermined direction, the stretchability in the predetermined direction is generated. However, the orientation of all the fibers is not necessarily only in the predetermined direction, and therefore the stretchability is also generated in the direction orthogonal to the predetermined direction.

肌膚側薄片213、223、非肌膚側薄片214、224、及伸縮性不織布215、225係藉由分散存在的複數個熔接部25a、25b(例如實施有超音波熔接之區域)接合，故，比起例如藉由固化之接著劑接合之情況，肌膚觸感變得柔軟。又，在熔接部25a、25b之間，藉由伸縮性不織布215、225收縮，使得肌膚側薄片213、223及非肌膚側薄片214、224朝厚度方向的外側彎曲並突出。亦即，肌膚側薄片213、223及非肌膚側薄片214、224在熔接部25a、25b之間膨出，故，肌膚觸感變得更柔軟，在視覺上對使用者亦可賦予柔軟的印象。The skin side sheets 213 and 223, the non-skin side sheets 214 and 224, and the stretchable nonwoven fabrics 215 and 225 are joined by a plurality of welded portions 25a and 25b (for example, regions in which ultrasonic welding is performed). The skin feels soft, for example, by bonding with a curing adhesive. In addition, the stretchable nonwoven fabrics 215 and 225 are contracted between the welded portions 25a and 25b, and the skin side sheets 213 and 223 and the non-skin side sheets 214 and 224 are bent outward in the thickness direction. In other words, the skin side sheets 213 and 223 and the non-skin side sheets 214 and 224 are bulged between the welded portions 25a and 25b, so that the skin feels softer and visually gives the user a soft impression. .

藉由這樣的結構，前側皮帶部21及後側皮帶部22全體在紙尿布1之左右方向(及上下方向)具有伸縮性。將在前側皮帶部21產生左右方向的伸縮性之區域稱為前側伸縮區域21s、將在後側皮帶部22產生左右方向的伸縮性之區域稱為後側伸縮區域22s(參照圖5的陰影部分)。又，熔接部25a、25b係如圖2所示，以較狹窄的間隔分散存在。因此，在本實施形態的紙尿布1，可產生朝多方向延伸且纖細的突出(皺紋)，可防止紙尿布特有的一方向之皺紋(縱向皺紋)產生，因此紙尿布1的美觀性佳。With such a configuration, the entire front belt portion 21 and the rear belt portion 22 are stretchable in the left-right direction (and the vertical direction) of the disposable diaper 1. A region in which the front side belt portion 21 is stretched in the left-right direction is referred to as a front side stretch region 21s, and a region in which the rear side belt portion 22 is stretched in the left-right direction is referred to as a rear side stretch region 22s (refer to the shaded portion of FIG. 5). ). Further, the welded portions 25a and 25b are dispersed at a relatively narrow interval as shown in Fig. 2 . Therefore, in the disposable diaper 1 of the present embodiment, fine protrusions (wrinkles) extending in a plurality of directions can be generated, and wrinkles (longitudinal wrinkles) in one direction peculiar to the disposable diaper can be prevented, so that the appearance of the disposable diaper 1 is excellent.

再者，亦可使用伸縮性薄膜，取代伸縮性不織布215、225。但，由於伸縮性薄膜之厚度大致均等，故，熔接部25a、25b之間的肌膚側薄片213、223及非肌膚側薄片214、224之突出容易被壓潰。相對於此，伸縮性不織布215、225係厚度在熔接部25a、25b之間增加，故，肌膚側薄片213、223及非肌膚側薄片214、224之突出不易被壓潰，能夠保持肌膚觸感之柔軟度、美觀性等。Further, a stretchable film may be used instead of the stretchable nonwoven fabrics 215 and 225. However, since the thickness of the stretchable film is substantially equal, the protrusions of the skin-side sheets 213 and 223 and the non-skin side sheets 214 and 224 between the welded portions 25a and 25b are easily crushed. On the other hand, since the thickness of the stretchable nonwoven fabrics 215 and 225 is increased between the welded portions 25a and 25b, the protrusions of the skin-side sheets 213 and 223 and the non-skin side sheets 214 and 224 are less likely to be crushed, and the skin feel can be maintained. Softness, aesthetics, etc.

又，熔接部25a、25b分散存在的區域中，在與吸收性本體10在厚度方向上重疊之第1分散存在區域X、其以外的第2分散存在區域Y，可使熔接部25a、25b的形狀、每單位面積的熔接部25a、25b的比例等不同。再者，在圖2中，在第1分散存在區域X，對左右方向傾斜45度或-45度之略長方形狀的熔接部25a交互地配置。另外，在第2分散存在區域Y，圓形狀之熔接部25b配置成鋸齒狀。Further, in the region in which the welded portions 25a and 25b are dispersed, the first dispersed region X and the other second dispersed region Y which are overlapped with the absorbent body 10 in the thickness direction can be used for the welded portions 25a and 25b. The shape and the ratio of the welded portions 25a and 25b per unit area are different. In addition, in FIG. 2, in the first dispersion existence region X, the substantially rectangular-shaped welded portions 25a which are inclined by 45 degrees or -45 degrees in the left-right direction are alternately arranged. Further, in the second dispersed region Y, the circular welded portion 25b is arranged in a zigzag shape.

又，比起第1分散存在區域X，第2分散存在區域Y之每單位面積的熔接部25b的面積變得較小。因此，在容易產生汗、悶熱等的問題之腰圍區域211、221，可防止因熔接部25b阻礙通氣性，可確保適當的通氣性。另外，在與吸收性本體10重複之第1分散存在區域X，前側皮帶部21及後側皮帶部22的收縮被適當地抑制，可減輕吸收性本體10的左右方向之收縮。Moreover, the area of the welded portion 25b per unit area of the second dispersed existence region Y is smaller than that of the first dispersed region X. Therefore, in the waist regions 211 and 221 which are prone to problems such as sweat and suffocation, it is possible to prevent the air permeability from being impeded by the welded portion 25b, and it is possible to ensure appropriate air permeability. In addition, in the first dispersion existing region X overlapping with the absorbent main body 10, the contraction of the front side belt portion 21 and the rear side belt portion 22 is appropriately suppressed, and the contraction of the absorbent main body 10 in the left-right direction can be reduced.

又，在前側皮帶部21及後側皮帶部22，於沿著腰圍開口1a之區域，配置有橡膠線等之複數個腰圍彈性構件26。同樣地，於沿著腳圍開口1b之區域，配置有橡膠線等之複數個腳圍彈性構件27。亦即，紙尿布1的腰圍及腳圍係藉由腰圍彈性構件26及腳圍彈性構件27，穩固地密接於穿用者的身體，因此，可防止紙尿布1之滑落、自腳圍之洩漏等。另外，其他部位是藉由伸縮性不織布215、225以面全體平緩地貼身於穿用者的身體，因此可減輕束緊感。Further, in the front side belt portion 21 and the rear side belt portion 22, a plurality of waist elastic members 26 such as rubber threads are disposed in a region along the waist opening 1a. Similarly, a plurality of foot elastic members 27 such as rubber threads are disposed along the region of the foot opening 1b. That is, the waist circumference and the foot circumference of the disposable diaper 1 are firmly adhered to the wearer's body by the waist elastic member 26 and the foot elastic member 27, thereby preventing the diaper 1 from slipping and leaking from the foot circumference. Wait. In addition, since the other portions are gently attached to the wearer's body by the stretchable nonwoven fabrics 215 and 225, the tightening feeling can be reduced.

褲襠構件23係形成為在長度方向的中央部分朝左右方向的內側彎曲之平面視角呈略沙漏時鐘形狀。又，如圖3所示，褲襠構件23係具有：位於肌膚側之肌膚側薄片231；位於非肌膚側之非肌膚側薄片232；及位於該等薄片之間，且在紙尿布1的上下方向(吸收性本體10的長度方向)上具有伸縮性之伸縮性不織布233。該等薄片231～233係藉由複數個熔接部(例如與第2分散存在區域Y相同的熔接部25b)接合。在褲襠構件23，將產生沿著上下方向的伸縮性之區域設為褲襠伸縮區域23s(參照圖5的斜線部分)。The crotch member 23 is formed in a slightly hourglass clock shape in a plane view angle in which the central portion in the longitudinal direction is curved toward the inner side in the left-right direction. Further, as shown in FIG. 3, the crotch member 23 has a skin side sheet 231 on the skin side, a non-skin side sheet 232 on the non-skin side, and a sheet 232 between the sheets and in the up and down direction of the sheet diaper 1. A stretchable nonwoven fabric 233 having elasticity (in the longitudinal direction of the absorbent body 10). The sheets 231 to 233 are joined by a plurality of welded portions (for example, the same welded portions 25b as the second dispersed present region Y). In the crotch member 23, a region in which the stretchability in the vertical direction is generated is referred to as a crotch expansion-contraction region 23s (see a hatched portion in FIG. 5).

藉由設至此褲襠伸縮區域23s，使得吸收性芯材11可密接於穿用者的褲襠部，又，即使因***造成吸收性芯材11的重量增加，也能夠抑制紙尿布1下垂。又，在褲襠構件23中之沿著腳圍開口1b的區域，配置有複數個褲襠彈性構件28，褲襠構件23密接於穿用者的腳圍。By providing the crotch stretchable region 23s, the absorbent core member 11 can be in close contact with the crotch portion of the wearer, and even if the weight of the absorbent core member 11 is increased due to excretion, the disposable diaper 1 can be prevented from sagging. Further, in the region of the crotch member 23 along the foot opening 1b, a plurality of crotch elastic members 28 are disposed, and the crotch member 23 is in close contact with the wearer's foot.

＜＜關於吸收性芯材11的變形＞＞
說明關於當穿用紙尿布1時，吸收性芯材11(吸收性本體10)配合穿用者的身體的動作產生變形之樣子。<<About the deformation of the absorbent core material 11>>
It is explained that when the disposable diaper 1 is worn, the absorbent core 11 (absorbent body 10) is deformed in conformity with the action of the wearer's body.

圖5係展開且伸長狀態之紙尿布1的概略平面圖，說明各種伸縮區域(21s、22s、23s)與吸收性芯材11之位置關係的圖。圖6係從肌膚側觀看吸收性芯材11之平面圖。Fig. 5 is a schematic plan view of the disposable diaper 1 in an expanded state, and shows a positional relationship between the various stretchable regions (21s, 22s, 23s) and the absorbent core member 11. Fig. 6 is a plan view of the absorbent core 11 viewed from the skin side.

如圖5所示，吸收性芯材11係具有當穿用時位於穿用者的下腹部之[下腹部位11A]；位於穿用者的褲襠部之[褲襠部位11B]；及位於穿用者的臀部之[臀部位11C]。在圖5，將與前側皮帶部21重複之部位設為下腹部位11A、與後側皮帶部22重複之部位設為臀部位11C、該等之間的部位設為褲襠部位11B。亦即，下腹部位11A係位於紙尿布1的前側部10F之部位，臀部位11C係位於紙尿布1的後側部10R之部位。又，褲襠部位11B係位於短褲形狀的紙尿布1之上下方向的下端部，跨越預定位置CL而設在遍及前側部10F與後側部10R之部位。As shown in FIG. 5, the absorbent core member 11 has a [lower abdomen position 11A] which is located on the wearer's lower abdomen when worn; a [pant area 11B] which is located in the wearer's crotch portion; and is located in the wearer. The hips [buttocks 11C]. In Fig. 5, a portion overlapping the front side belt portion 21 is referred to as a lower abdomen position 11A, a portion overlapping the rear side belt portion 22 is referred to as a buttock position 11C, and a portion between the portions is referred to as a crotch portion 11B. That is, the lower abdomen position 11A is located at a portion of the front side portion 10F of the disposable diaper 1, and the buttocks position 11C is located at a portion of the rear side portion 10R of the disposable diaper 1. Further, the crotch portion 11B is located at a lower end portion of the pants-shaped disposable diaper 1 in the lower direction, and is provided over the front side portion 10F and the rear side portion 10R across the predetermined position CL.

但，圖5所示的[褲襠部位11B]之範圍僅為一例，不限於此。例如，亦可在長度方向上，將從前側皮帶部21的端部接合區域24之下端到後側皮帶部22的端部接合區域24的下端為止之區域作成為1/3時的中央區域作為褲襠部位。However, the range of the [leg portion 11B] shown in FIG. 5 is only an example, and is not limited thereto. For example, in the longitudinal direction, the region from the lower end of the end joint region 24 of the front belt portion 21 to the lower end of the end joint region 24 of the rear belt portion 22 may be a central region of 1/3. The crotch area.

吸收性芯材11係在較紙尿布1的上下方向的下端(相當於預定位置CL的位置)更上側且前後方向的前側(前側部10F)，具有比起周圍，吸收性芯材11的基重變低之區域亦即[傾斜低基重區域31]。在傾斜低基重區域31，含有第1傾斜低基重區域311；及配置於較第1傾斜低基重區域311更靠近左右方向的內側之第2傾斜低基重區域312。各自的傾斜低基重區域311、312係為從上下方向的上側朝下側且從左右方向的外側朝中心側傾斜之區域，在吸收性芯材11的前側，左右各設有一對。又，在紙尿布1，第1傾斜低基重區域311與第2傾斜低基重區域312係平行地配置。The absorbent core member 11 is provided on the lower side (the position corresponding to the predetermined position CL) in the vertical direction of the disposable diaper 1 and the front side (the front side portion 10F) in the front-rear direction, and has a base of the absorbent core member 11 in comparison with the periphery. The area where the weight is lowered is also [tilted low basis weight area 31]. The inclined low basis weight region 31 includes a first inclined low basis weight region 311; and a second inclined low basis weight region 312 disposed closer to the inner side in the left-right direction than the first inclined low basis weight region 311. Each of the inclined low basis weight regions 311 and 312 is a region that is inclined downward from the upper side in the up-and-down direction and from the outer side in the left-right direction toward the center side, and a pair is provided on the front side of the absorbent core member 11 on the left and right sides. Further, in the disposable diaper 1, the first inclined low basis weight region 311 and the second inclined low basis weight region 312 are arranged in parallel.

再者，吸收性芯材11的[基重]係指每單位面積之吸收性芯材11(例如混入有SAP吸液性纖維)的質量(g/m2 )。傾斜低基重區域31與周圍的區域之吸收性芯材11的基重的比較，藉由習知的方法進行即可。例如，具有以目視進行比較的方法。其他亦有下述方法，即，將對象部位作為樣品而從吸收性芯材11切出，測定各樣品的質量及各樣品的面積，算出每單位面積的質量後進行比較之方法。關於以下進行說明的其他低基重區域也相同。In addition, the [basis weight] of the absorptive core material 11 means the mass (g/m 2 ) of the absorptive core material 11 per unit area (for example, the SAP liquid-absorbent fiber is mixed). The comparison of the basis weight of the absorbent core member 11 of the inclined low basis weight region 31 and the surrounding region can be carried out by a conventional method. For example, there is a method of visually comparing. There is also a method in which the target portion is cut out from the absorbent core material 11 as a sample, and the mass of each sample and the area of each sample are measured, and the mass per unit area is calculated and compared. The other low basis weight regions described below are also the same.

吸收性芯材11係藉由傾斜低基重區域31與周圍的區域之剛性差，以傾斜低基重區域31作為起點而容易折彎。因此，在穿用紙尿布1時，吸收性芯材11係藉由以此傾斜低基重區域31作為起點而折彎，使得容易配合穿用者的身體的凹凸而變形，變得容易貼身於穿用者的身體。尤其是此傾斜低基重區域31係從穿用者的恥骨周邊到腹股溝斜向抵接。亦即，會成為沿著穿用者的腳之根部的形狀之折彎起點。因此，即使在穿用者行走或腳向前後移動等之情況，在穿用者的腹部側，吸收性芯材11也能追隨腳的動作，三維地折彎，可配合身體的動作而容易自由地變形。The absorbent core member 11 is easily bent by tilting the low basis weight region 31 as a starting point by the difference in rigidity between the inclined low basis weight region 31 and the surrounding region. Therefore, when the disposable diaper 1 is worn, the absorbent core member 11 is bent by using the inclined low basis weight region 31 as a starting point, so that it is easy to be deformed in conformity with the unevenness of the wearer's body, and it becomes easy to fit around. The user's body. In particular, the inclined low basis weight region 31 abuts obliquely from the pubic periphery of the wearer to the groin. That is, it will become the starting point of the bend along the shape of the root of the wearer's foot. Therefore, even in the case where the wearer walks or the foot moves forward or backward, the absorbent core member 11 can follow the movement of the foot on the abdomen side of the wearer, and can be bent three-dimensionally, and can be easily combined with the movement of the body. Ground deformation.

又，如圖6所示，吸收性芯材11係在較紙尿布1的上下方向的下端(參照圖1)更上側且前後方向的前側(前側部10F)，具有比起周圍，吸收性芯材11的基重變低之區域亦即[中央低基重區域32]。中央低基重區域32係在吸收性芯材11的左右方向之中央部，沿著上下方向(長度方向)配置，吸收性芯材11的基重比周圍低，且比起紙尿布1的左右方向，對上下方向較長之略長方形狀的區域。同樣地，在較紙尿布1的上下方向的下端更上側且前後方向的後側(後側部10R)，設有與中央低基重區域32相對應的[中央低基重區域33]。在本實施形態，設為在中央低基重區域32、33不存在有吸收性芯材11者。亦即，中央低基重區域32、33係吸收性芯材11朝厚度方向貫通之孔。Moreover, as shown in FIG. 6, the absorptive core material 11 is the upper side (front side part 10F) of the upper side of the upper-diameter direction (refer the FIG. The region where the basis weight of the material 11 becomes lower is also [the central low basis weight region 32]. The central low basis weight region 32 is disposed in the center portion of the absorbent core member 11 in the left-right direction, and is disposed in the vertical direction (longitudinal direction). The basis weight of the absorbent core member 11 is lower than that of the periphery, and is higher than that of the disposable diaper 1 Direction, a slightly rectangular area that is long in the up and down direction. Similarly, the [central low basis weight region 33] corresponding to the central low basis weight region 32 is provided on the upper side in the up-and-down direction of the paper diaper 1 and the rear side (rear side portion 10R) in the front-rear direction. In the present embodiment, the absorptive core material 11 is not present in the central low basis weight regions 32 and 33. That is, the central low basis weight regions 32 and 33 are holes through which the absorbent core member 11 penetrates in the thickness direction.

再者，在吸收性芯材11，除了前述傾斜低基重區域31、中央低基重區域32、33等以外，還設有比起周囲的的區域，吸收性芯材11的基重變低之複數個[低基重區域](參照圖6)。Further, in the absorbent core member 11, in addition to the inclined low basis weight region 31, the central low basis weight regions 32, 33, and the like, a region lower than the peripheral ridge is provided, and the basis weight of the absorbent core member 11 is lowered. A plurality of [low basis weight regions] (see Fig. 6).

其次，具體地說明關於穿用紙尿布1時之吸收性芯材11的變形。圖7係說明關於穿用紙尿布1時之吸收性芯材11的變形之概略斜視圖。Next, the deformation of the absorbent core member 11 when the disposable diaper 1 is worn will be specifically described. Fig. 7 is a schematic perspective view showing the deformation of the absorbent core member 11 when the disposable diaper 1 is worn.

在紙尿布1，在中央低基重區域32、33，吸收性芯材11朝厚度方向被貫通，剛性變得最低。因此，吸收性芯材11係在中央低基重區域32、33，變得最容易產生折彎變形。因此，當穿用紙尿布1時，吸收性芯材11在穿用者的***部夾入於兩腳的話，則該吸收性芯材11在中央低基重區域32、33的部分，沿著上下方向(吸收性芯材11的長度方向)朝左右折彎。藉此，在長度方向上之中央低基重區域32、33之間的褲襠部位11B，如圖7所示，吸收性芯材11沿著長度方向朝穿用者的肌膚側呈凸狀變形，形成凸部11t。亦即，中央低基重區域32、33係具有將在吸收性芯材11在褲襠部位11B沿著長度方向折彎之[折彎誘導區域]之功能。藉由吸收性芯材11在褲襠部位11B朝肌膚側凸狀變形，凸部11t沿著穿用者的***口、臀部的股溝等容易貼身，在褲襠部可使***物的吸收性提升。In the disposable diaper 1, in the center low basis weight regions 32 and 33, the absorbent core member 11 is penetrated in the thickness direction, and the rigidity is minimized. Therefore, the absorbent core material 11 is in the center low basis weight regions 32 and 33, and the bending deformation is most likely to occur. Therefore, when the disposable diaper 1 is worn, the absorbent core member 11 is sandwiched between the feet of the wearer's crotch, the absorbent core 11 is in the central low basis weight region 32, 33, along the upper and lower sides. The direction (the longitudinal direction of the absorbent core material 11) is bent toward the left and right. Thereby, in the crotch portion 11B between the central low basis weight regions 32 and 33 in the longitudinal direction, as shown in FIG. 7, the absorbent core member 11 is convexly deformed toward the wearer's skin side along the longitudinal direction. The convex portion 11t is formed. That is, the central low basis weight regions 32 and 33 have a function of bending the absorption core member 11 in the longitudinal direction of the crotch portion 11B. The absorbent core member 11 is convexly deformed toward the skin side at the crotch portion 11B, and the convex portion 11t is easily attached to the wearer's excretory opening, the groin of the buttocks, and the like, and the absorbent property of the excrement can be improved in the crotch portion.

又，在前側部10F，從褲襠部位11B到下腹部位11A，吸收性芯材11沿著穿用者的腹部之曲面形狀立起。又，在後側部10R，從褲襠部位11B到臀部位11C，吸收性芯材11沿著穿用者的臀部之曲面形狀立起。藉此，在穿用紙尿布1時，吸收性芯材11可變形為如圖7這樣的形狀。Further, in the front side portion 10F, from the crotch portion 11B to the lower abdomen position 11A, the absorbent core member 11 stands up along the curved surface shape of the wearer's abdomen. Further, in the rear side portion 10R, from the crotch portion 11B to the buttock position 11C, the absorbent core member 11 stands up along the curved shape of the wearer's buttocks. Thereby, when the disposable diaper 1 is worn, the absorptive core material 11 can be deformed into the shape like FIG.

又，中央低基重區域32的短邊方向之寬度d32係較傾斜低基重區域31的短邊方向之寬度d31大(d32＞d31)。因此，中央低基重區域32之剛性較傾斜低基重區域31小，變得更容易產生折彎變形。因此，藉由吸收性芯材11夾入於穿用者的腹股溝，使得中央低基重區域32、33之間的區域最先被折彎，接著傾斜低基重區域31形成為折彎變形的起點。藉此，當穿用紙尿布1時，吸收性芯材11在中央低基重區域32、33之間，容易沿著穿用者的身體形狀產生凸變形。又，在穿用後，吸收性芯材11可容易因應穿用者的腳之動作，沿著傾斜低基重區域31自然地變形。Further, the width d32 of the short-side direction of the central low basis weight region 32 is larger than the width d31 of the short-side direction of the inclined low basis weight region 31 (d32>d31). Therefore, the rigidity of the central low basis weight region 32 is smaller than that of the inclined low basis weight region 31, and it becomes easier to cause bending deformation. Therefore, by sandwiching the absorbent core 11 into the groin of the wearer, the area between the central low basis weight regions 32, 33 is first bent, and then the inclined low basis weight region 31 is formed into a bent deformation. starting point. Thereby, when the disposable diaper 1 is worn, the absorbent core material 11 is easily deformed along the shape of the wearer's body between the central low basis weight regions 32 and 33. Further, after wearing, the absorbent core member 11 can be easily deformed naturally along the inclined low basis weight region 31 in response to the action of the wearer's foot.

但，因吸收性芯材11對穿用者的肌膚以具有凹凸的方式三維地變形，使得會產生吸收性芯材11從穿用者的肌膚浮起之部分，在此狀態下，在一部分的區域會有貼身性惡化之虞。圖8係說明關於吸收性芯材11從穿用者的身體(肌膚)浮起的狀態之概略斷面圖。在該圖8，顯示關於從上側觀看時的穿用者之下腹部位置的斷面、及在下腹部位11A產生變形的吸收性芯材11之斷面形狀。However, since the absorbent core material 11 is three-dimensionally deformed to the wearer's skin so as to have irregularities, the absorbent core 11 is caused to float from the wearer's skin, and in this state, in part The area will have a deterioration in personal fit. Fig. 8 is a schematic cross-sectional view showing a state in which the absorbent core member 11 is lifted from the wearer's body (skin). In Fig. 8, the cross section of the lower abdominal portion of the wearer when viewed from the upper side and the cross-sectional shape of the absorbent core 11 deformed at the lower abdominal position 11A are shown.

在穿用者的下腹部，吸收性芯材11係如圖8所示，變形成斷面略W字形。亦即，在左右方向的中央部，產生朝穿用者的肌膚側形成凸之折彎變形，形成凸部11t。另外，在凸部11t的左右方向的兩側，以一對傾斜低基重區域31為起點，朝穿用者的肌膚側成為凹狀的方式產生折彎變形。其結果，藉由傾斜低基重區域31所折彎之部分係在與穿用者的肌膚之間容易產生間隙。又，由於吸收性芯材11因夾入於穿用者的雙腳，會受到左右方向的壓縮力，故，容易朝非肌膚側浮起，而形成吸收性芯材11的左右方向的中央部從兩端部被推出。亦即，會有因吸收性芯材11產生三維地折彎變形，造成不易貼身於穿用者的肌膚之虞。In the lower abdomen of the wearer, the absorbent core member 11 is formed into a substantially W-shaped cross section as shown in Fig. 8 . In other words, in the central portion in the left-right direction, a bending deformation that is convex toward the wearer's skin side is generated, and the convex portion 11t is formed. Further, on both sides in the left-right direction of the convex portion 11t, a pair of inclined low basis weight regions 31 are used as a starting point, and bending deformation occurs in a concave shape toward the wearer's skin side. As a result, the portion bent by tilting the low basis weight region 31 is likely to cause a gap between the wearer's skin and the skin of the wearer. In addition, since the absorbent core member 11 is subjected to a compressive force in the left-right direction by being caught in the wearer's feet, it is easy to float toward the non-skin side, and the center portion of the absorbent core member 11 in the left-right direction is formed. It is pushed out from both ends. That is, there is a three-dimensional bending deformation of the absorbent core material 11, which causes it to be difficult to fit on the wearer's skin.

相對於此，在本實施形態的紙尿布1，吸收性芯材11的傾斜低基重區域31全體係與前側皮帶部21的前側伸縮區域21s重複(參照圖5)。亦即，在吸收性芯材11，對於配置有傾斜低基重區域31之區域，左右方向的伸縮性會作用。藉此，可使以傾斜低基重區域31為起點進行折彎變形之吸收性芯材11密接於穿用者的肌膚。圖9係說明關於在圖8中，藉由前側伸縮區域21s之左右方向的收縮力作用於吸收性芯材11的情況之概略斷面圖。On the other hand, in the disposable diaper 1 of the present embodiment, the entire inclined low basis weight region 31 of the absorbent core member 11 overlaps with the front side stretchable region 21s of the front side belt portion 21 (see FIG. 5). That is, in the region in which the absorbent core member 11 is disposed with the inclined low basis weight region 31, the stretchability in the left-right direction acts. Thereby, the absorbent core material 11 which is bent and deformed from the inclined low basis weight region 31 can be brought into close contact with the wearer's skin. FIG. 9 is a schematic cross-sectional view showing a state in which the contraction force in the left-right direction of the front side expansion and contraction region 21s acts on the absorbent core member 11 in FIG.

在圖9，變形成朝穿用者的肌膚側成為凹狀的吸收性芯材11之傾斜低基重區域31的部分係藉由前側伸縮區域21s，從穿用者的非肌膚側朝肌膚側按壓。亦即，吸收性芯材11係藉由追隨穿用者的身體的動作進行折彎變形，且藉由前側伸縮區域21s之左右方向的收縮力從非肌膚側作用，使得吸收性芯材11密接於穿用者的肌膚，在吸收性芯材11與穿用者的肌膚之間不易產生間隙。因此，可使穿用者的恥骨附近之吸收性芯材11的貼身性提升。In Fig. 9, the portion of the inclined low basis weight region 31 which is formed into a concave shape toward the wearer's skin side is formed by the front side stretchable region 21s from the non-skin side of the wearer toward the skin side. Press. In other words, the absorbent core member 11 is bent and deformed by following the action of the wearer's body, and the contraction force in the left-right direction of the front side stretchable region 21s acts from the non-skin side, so that the absorbent core member 11 is in close contact with each other. In the wearer's skin, a gap is unlikely to occur between the absorbent core material 11 and the wearer's skin. Therefore, the fit of the absorbent core member 11 in the vicinity of the pubis of the wearer can be improved.

再者，吸收性芯材11的傾斜低基重區域31並非一定需要全體與前側伸縮區域21s重複。例如，若傾斜低基重區域31的上下方向上之端部未接受藉由前側伸縮區域21s之伸縮力，而是端部以外的區域接收伸縮力的話，亦可如圖9所示一樣，可充分地貼身於穿用者的身體。Further, the inclined low basis weight region 31 of the absorbent core member 11 does not necessarily have to be entirely overlapped with the front side stretch region 21s. For example, if the end portion of the inclined low basis weight region 31 in the up and down direction does not receive the stretching force by the front side expansion and contraction region 21s, but the region other than the end portion receives the stretching force, it may be as shown in FIG. Fully close to the wearer's body.

又，在前側部10F，一對傾斜低基重區域31的上下方向上之下端31ed係位於較中央低基重區域32的下端32ed更高的位置。如前述般，中央低基重區域32係在褲襠部位11B，作為用來將吸收性芯材11凸變形之折彎誘導區域發揮功能，故，期望設在接近穿用者的褲襠部之位置。另外，由於傾斜低基重區域31係成為因應穿用者的腳的動作，使吸收性芯材11變形之起點，故，期望設在穿用者的恥骨附近。再者，一對傾斜低基重區域31的下端31ed係指第1傾斜低基重區域311的下端311ed與第2傾斜低基重區域312的下端312ed中的位於上下方向之下側者。在本實施形態，第1傾斜低基重區域311的下端311ed為傾斜低基重區域31的下端31ed(參照圖6)。Further, in the front side portion 10F, the lower end 31ed in the up-and-down direction of the pair of inclined low basis weight regions 31 is located higher than the lower end 32ed of the central low-basis weight region 32. As described above, the central low basis weight region 32 is provided in the crotch portion 11B and functions as a bending inducing region for convexly deforming the absorbent core member 11. Therefore, it is desirable to provide a position close to the crotch portion of the wearer. Further, since the inclined low basis weight region 31 serves as a starting point for deforming the absorbent core member 11 in response to the action of the wearer's foot, it is desirable to provide it in the vicinity of the pubis of the wearer. Further, the lower end 31ed of the pair of inclined low basis weight regions 31 means the lower end 311ed of the first inclined low basis weight region 311 and the lower end 312ed of the second inclined low basis weight region 312 which are located below the upper and lower sides. In the present embodiment, the lower end 311ed of the first inclined low basis weight region 311 is the lower end 31ed of the inclined low basis weight region 31 (see Fig. 6).

同樣地，在前側部10F，一對傾斜低基重區域31的上下方向上之上端31eu係位於較中央低基重區域32的上端32eu更高的位置。較中央低基重區域32更靠近上下方向的上側之區域係為當穿用紙尿布1時，抵接於穿用者的腹部之區域，接***面的區域(參照圖7)，因此，在該區域，為了使吸收性芯材11不易變形，將上端32eu的位置作成不會過高。另外，傾斜低基重區域31係為了可追隨穿用者的腳的動作而變形直到吸收性芯材11的上方，將上端31eu配置成盡可能變高。再者，一對傾斜低基重區域31的上端31eu係指第1傾斜低基重區域311的上端311eu與第2傾斜低基重區域312的上端312eu中之位於上下方向的上側者。在本實施形態，第1傾斜低基重區域311的上端311eu與第2傾斜低基重區域312的上端312eu之高度相等，兩者成為傾斜低基重區域31的上端31eu。Similarly, in the front side portion 10F, the upper end 31eu of the pair of inclined low basis weight regions 31 in the up and down direction is located higher than the upper end 32eu of the central low basis weight region 32. The region closer to the upper side in the up-and-down direction than the central low basis weight region 32 is a region that abuts against the wearer's abdomen when the disposable diaper 1 is worn, and is close to a plane (refer to FIG. 7), and therefore, in this region In order to prevent the absorbent core material 11 from being easily deformed, the position of the upper end 32eu is not excessively high. Further, the inclined low basis weight region 31 is deformed so as to follow the movement of the wearer's foot until the upper side of the absorbent core member 11, and the upper end 31eu is disposed as high as possible. Further, the upper end 31eu of the pair of inclined low basis weight regions 31 refers to the upper side in the vertical direction of the upper end 311eu of the first inclined low basis weight region 311 and the upper end 312eu of the second inclined low basis weight region 312. In the present embodiment, the upper end 311eu of the first inclined low basis weight region 311 and the upper end 312eu of the second inclined low basis weight region 312 are equal to each other, and both of them become the upper end 31eu of the inclined low basis weight region 31.

又，本實施形態的吸收性芯材11係在一對第1傾斜低基重區域311的左右方向之內側，具有一對第2傾斜低基重區域312，但，此第1傾斜低基重區域311及第2傾斜低基重區域312皆成為吸收性芯材11的折彎起點。在本實施形態，藉由在左右方向上具有複數個這樣的折彎起點，使吸收性芯材11可階段性地變形。亦即，藉由在左右方向上設置複數個折彎起點，使吸收性芯材11可更圓滑地折彎，在穿用者的恥骨附近容易形成沿著身體形狀之三維曲面。Further, the absorbent core member 11 of the present embodiment has a pair of second inclined low basis weight regions 312 inside the left and right directions of the pair of first inclined low basis weight regions 311, but the first inclined low basis weight Both the region 311 and the second inclined low basis weight region 312 become the starting point of the bending of the absorbent core member 11. In the present embodiment, the absorbent core member 11 can be deformed stepwise by having a plurality of such bending starting points in the left-right direction. That is, by providing a plurality of bending starting points in the left-right direction, the absorbent core member 11 can be more smoothly bent, and a three-dimensional curved surface along the body shape can be easily formed in the vicinity of the pubis of the wearer.

又，藉由第1傾斜低基重區域311的長度方向上之長度形成為較第2傾斜低基重區域312的長度方向上之長度長，使得可更容易追隨身體的動作。藉由這樣的結構，在配置於左右方向的內側之一對第2傾斜低基重區域312，折彎起點變短，因此，在該內側的區域，吸收性芯材11的折彎變形變小。另外，在配置於左右方向的外側之一對第1傾斜低基重區域311，折彎起點變長，因此，在該外側的區域，吸收性芯材11的折彎變形變大。因此，吸收性芯材11係在接近穿用者的腳之左右方向的外側之區域，更容易變形而更容易追隨腳的動作。Further, the length in the longitudinal direction of the first inclined low basis weight region 311 is formed to be longer than the length in the longitudinal direction of the second inclined low basis weight region 312, so that the movement of the body can be more easily followed. With such a configuration, the bending starting point is shortened in one of the inner side in the left-right direction and the second inclined low-base area 312. Therefore, the bending deformation of the absorbent core member 11 is small in the inner region. . In addition, since one of the outer sides disposed in the left-right direction and the first inclined low basis weight region 311 has a long bending starting point, the bending deformation of the absorbent core member 11 is increased in the outer region. Therefore, the absorbent core member 11 is in a region close to the outer side in the left-right direction of the wearer's foot, and is more easily deformed to more easily follow the movement of the foot.

且，在上下方向，第1傾斜低基重區域311的下端311ed之位置，係較第2傾斜低基重區域312的下端312ed之位置低。如此，藉由使第1傾斜低基重區域311延伸至上下方向之盡可能低的位置，使得即使在接近穿用者的腹股溝之區域，吸收性芯材11也變得容易產生折彎變形，可更容易追隨穿用者的腳之動作。Further, in the vertical direction, the position of the lower end 311ed of the first inclined low basis weight region 311 is lower than the position of the lower end 312ed of the second inclined low basis weight region 312. By extending the first inclined low basis weight region 311 to a position as low as possible in the vertical direction, the absorbent core member 11 is likely to be bent and deformed even in a region close to the groin of the wearer. It is easier to follow the wearer's foot movements.

又，在第1傾斜低基重區域311的上端311eu的上下方向之上側，連接有沿著上下方向(長度方向)之第1上側低基重區域341，在第1傾斜低基重區域311的下端311ed的上下方向之下側，連接有沿著上下方向之第1下側低基重區域351。亦即，第1上側低基重區域341的下端341ed與第1傾斜低基重區域311的上端311eu相連接，第1傾斜低基重區域311的下端311ed與第1下側低基重區域351的上端351eu相連接，第1上側低基重區域341與第1傾斜低基重區域311及第1下側低基重區域351連續於上下方向。Further, the first upper low basis weight region 341 in the vertical direction (longitudinal direction) is connected to the upper side in the vertical direction of the upper end 311eu of the first inclined low basis weight region 311, and the first oblique low basis weight region 311 is connected to the first inclined low basis weight region 311. The lower side of the lower end 311 id is connected to the first lower low basis weight region 351 in the vertical direction. That is, the lower end 341ed of the first upper low basis weight region 341 is connected to the upper end 311eu of the first inclined low basis weight region 311, and the lower end 311ed of the first inclined low basis weight region 311 and the first lower low basis weight region 351. The upper end 351 eu is connected, and the first upper low basis weight region 341 and the first inclined low basis weight region 311 and the first lower low basis weight region 351 are continuous in the vertical direction.

若第1上側低基重區域341未連續地設在第1傾斜低基重區域311的上端311eu之情況，會有因吸收性芯材11的折彎變形所產生的扭曲、應力等集中於上端311eu，在該上端311eu產生吸收性芯材11破損或妨礙吸收性芯材11的自然變形等之虞。相對於此，在本實施形態，藉由第1上側低基重區域341連續地設在第1傾斜低基重區域311的上端311eu，可使應力等容易分散至第1上側低基重區域341側。同樣地，在本實施形態，藉由第1下側低基重區域351連續地設在第1傾斜低基重區域311的下端311ed，可使應力等容易分散至第1下側低基重區域351側。藉此，在該區域，可使吸收性芯材11更自然地變形。When the first upper low basis weight region 341 is not continuously provided at the upper end 311eu of the first inclined low basis weight region 311, distortion, stress, and the like due to the bending deformation of the absorbent core member 11 are concentrated on the upper end. 311eu, at the upper end 311eu, the absorbent core 11 is broken or the natural deformation of the absorbent core 11 is hindered. On the other hand, in the present embodiment, the first upper low basis weight region 341 is continuously provided at the upper end 311eu of the first inclined low basis weight region 311, so that stress or the like can be easily dispersed to the first upper low basis weight region 341. side. Similarly, in the present embodiment, the first lower low basis weight region 351 is continuously provided at the lower end 311ed of the first inclined low basis weight region 311, so that stress or the like can be easily dispersed to the first lower low basis weight region. 351 side. Thereby, the absorbent core material 11 can be more naturally deformed in this region.

又，在第2傾斜低基重區域312的上端312eu的上下方向之上側，連接有沿著上下方向(長度方向)之第2上側低基重區域342。亦即，第2傾斜低基重區域312的上端312eu與第2上側低基重區域342的下端342ed相連接。與前述第1上側低基重區域341同樣地，此第2上側低基重區域342也可將因以第2傾斜低基重區域312為起點之折彎變形所產生的應力分散，可使吸收性芯材11更自然地變形。再者，在第2傾斜低基重區域312的下端312ed的上下方向之下側，未設有相當於第1下側低基重區域351之低基重區域。在第2傾斜低基重區域312，比起第1傾斜低基重區域311，吸收性芯材11的變形量較小，因此，扭曲、應力等的影響小，藉由第2上側低基重區域342可充分地將應力等分散。因此，在第2傾斜低基重區域312，即使在下側未設置低基重區域，亦可使吸收性芯材11自然地變形。Further, a second upper low basis weight region 342 along the vertical direction (longitudinal direction) is connected to the upper side in the vertical direction of the upper end 312eu of the second inclined low basis weight region 312. That is, the upper end 312eu of the second inclined low basis weight region 312 is connected to the lower end 342ed of the second upper low basis weight region 342. Similarly to the first upper low basis weight region 341, the second upper low basis weight region 342 can disperse the stress caused by the bending deformation starting from the second inclined low basis weight region 312, and can be absorbed. The core material 11 is more naturally deformed. Further, a lower basis weight region corresponding to the first lower low basis weight region 351 is not provided on the lower side in the up-and-down direction of the lower end 312ed of the second inclined low basis weight region 312. In the second inclined low basis weight region 312, the amount of deformation of the absorbent core member 11 is smaller than that of the first inclined low basis weight region 311. Therefore, the influence of distortion, stress, and the like is small, and the second upper side has a low basis weight. The region 342 can sufficiently disperse stress or the like. Therefore, in the second inclined low basis weight region 312, the absorbent core member 11 can be naturally deformed even if the low basis weight region is not provided on the lower side.

又，前側皮帶部21係在較端部接合區域24的下端更靠近下側的褲襠側區域212，具有朝上下方向的下側且左右方向的內側傾斜(亦即，朝褲襠部斜向傾斜)之傾斜部212s。當穿用紙尿布1時，前後的皮帶部21、22的左右方向之兩端部朝外側被拉引而腰圍開口1a擴大的話，則傾斜部212s也朝左右方向外側被拉引，與該傾斜部212s接合之吸收性本體10也被傾斜部212s拉引。亦即，藉由傾斜部212s，使吸收性本體10朝斜上方向拉起之力作用，吸收性本體10(吸收性芯材11)不易從穿用者的恥骨周邊偏移而能使貼身性提升。Further, the front side belt portion 21 is closer to the lower crotch side region 212 than the lower end of the end portion joining region 24, and has a lower side in the up-and-down direction and an inner side in the left-right direction (that is, inclined obliquely toward the crotch portion) The inclined portion 212s. When the disposable diaper 1 is worn, both ends of the front and rear belt portions 21 and 22 in the left-right direction are pulled outward, and when the waist opening 1a is enlarged, the inclined portion 212s is also pulled outward in the left-right direction, and the inclined portion is pulled. The 212s joined absorbent body 10 is also pulled by the inclined portion 212s. In other words, by the inclined portion 212s, the force of pulling up the absorbent body 10 in the obliquely upward direction acts, and the absorbent body 10 (absorbent core member 11) is less likely to be displaced from the wearer's pubic periphery to enable the fit. Upgrade.

在本實施形態，藉由前側伸縮區域21s之伸縮性的作用，朝向左右方向之拉引力容易傳達至傾斜部212s全體。且，藉由沿著傾斜部212s配置腳圍彈性構件27，使得傾斜部212s之拉引力容易作用於吸收性本體10。因此，例如即使在吸收性本體10吸收***物而變重之情況，也能將吸收性本體10穩固地拉起，容易抑制位置偏移。In the present embodiment, the pulling force in the left-right direction is easily transmitted to the entire inclined portion 212s by the action of the stretchability of the front side expansion and contraction region 21s. Further, by arranging the foot elastic member 27 along the inclined portion 212s, the pulling force of the inclined portion 212s is easily applied to the absorbent body 10. Therefore, for example, even when the absorbent body 10 absorbs excrement and becomes heavy, the absorbent body 10 can be firmly pulled up, and positional displacement can be easily suppressed.

其中，腳圍彈性構件27之產生伸縮性的區域與吸收性芯材11係未重複。藉此，當將吸收性本體10朝斜上方拉起時，多餘的力不易作用於吸收性芯材11本身，變得不易阻礙吸收性芯材11的折彎變形，又亦可抑制吸收性芯材11從穿用者的身體浮起。再者，腳圍彈性構件27係在前側皮帶部21的下端(下腹部位11A的下端)，沿著左右方向被切斷(參照圖5)。亦即，在腳圍彈性構件27的下端部，容易產生沿著上下方向之伸縮性，且不易產生沿著左右方向的伸縮性。因此，藉由腳圍彈性構件27之伸縮力，對配置於該腳圍彈性構件27的左右方向之內側的吸收性芯材11更不易作用。Among them, the region where the stretchable elastic member 27 is stretched and the absorbent core member 11 are not repeated. Thereby, when the absorbent body 10 is pulled up obliquely upward, the excess force does not easily act on the absorbent core material 11 itself, and it becomes difficult to hinder the bending deformation of the absorbent core material 11, and the absorbent core can be suppressed. The material 11 floats from the wearer's body. Further, the foot elastic member 27 is cut at the lower end of the front side belt portion 21 (the lower end of the lower abdominal portion 11A), and is cut along the left-right direction (see FIG. 5). In other words, in the lower end portion of the foot elastic member 27, the stretchability in the vertical direction is likely to occur, and the stretchability in the left-right direction is less likely to occur. Therefore, the elastic core member 11 disposed on the inner side in the left-right direction of the foot elastic member 27 is less likely to act by the expansion and contraction force of the foot elastic member 27.

又，在本實施形態的紙尿布1，傾斜部212s之對上下方向的傾斜角度θ212s係較傾斜低基重區域31之對上下方向的傾斜角度θ31大(θ212s＞θ31)。在此，對上下方向之傾斜角度係指如圖2所示，上下方向與傾斜部212s等所形成的角度中之較小的角度。在若傾斜部212s的傾斜角度θ212s較傾斜低基重區域31的傾斜角度θ31小之情況，吸收性本體10(吸收性芯材11)變得更容易朝上側拉引，對沿著傾斜低基重區域31折彎變形之吸收性芯材11，無法使左右方向的伸縮性充分地作用，造成吸收性芯材11容易從穿用者的肌膚浮起。又，會有在折彎變形的狀態之吸收性芯材11產生扭曲、應變等造成貼身性惡化之虞。相對於此，藉由將傾斜角度θ212s作成較傾斜角度θ31更大，既可使吸收性芯材11適當地變形，又可使左右方向的伸縮性穩固地作用，使得該吸收性芯材11容易密接於穿用者的肌膚，能夠使貼身性提升。Further, in the disposable diaper 1 of the present embodiment, the inclination angle θ212s of the inclined portion 212s in the vertical direction is larger than the inclination angle θ31 of the inclined low basis weight region 31 in the vertical direction (θ212s>θ31). Here, the inclination angle in the up-and-down direction means a smaller angle among the angles formed by the vertical direction and the inclined portion 212s as shown in FIG. 2 . When the inclination angle θ212s of the inclined portion 212s is smaller than the inclination angle θ31 of the inclined low basis weight region 31, the absorbent body 10 (absorbent core member 11) becomes easier to be pulled upward, and the pair is inclined toward the lower base. The absorbent core member 11 which is bent and deformed in the heavy region 31 does not sufficiently exert the stretchability in the left-right direction, and the absorbent core member 11 easily floats from the wearer's skin. Further, the absorbent core member 11 in a state of being bent and deformed may be deformed by strain, strain, or the like, which may deteriorate the fit. On the other hand, by making the inclination angle θ212s larger than the inclination angle θ31, the absorbent core material 11 can be appropriately deformed, and the stretchability in the left-right direction can be stably applied, making the absorbent core material 11 easy. It is close to the wearer's skin and can improve the fit.

又，在紙尿布1，在吸收性芯材11的左右方向上之寬度變窄的縮徑部11c中之部位11cmin，寬度變得最窄，左右方向之剛性也最低。又，此部位11cmin係與前側伸縮區域21s重複(參照圖6)。因此，此部位11cmin係在紙尿布1穿用時，容易形成為吸收性芯材11的之下腹部位11A從褲襠部朝下腹部側立起而變形時之變形起點。亦即，吸收性芯材11係在部位11cmin，容易變形，容易從穿用者的肌膚浮起。相對於此，在本實施形態，藉由對吸收性芯材11的左右方向上之寬度最窄的部位11cmin，藉由前側伸縮區域21s之左右方向的伸縮性會作用，可將已經浮起的吸收性芯材11按壓於穿用者的肌膚並密接。藉此，吸收性芯材11既可因應穿用者的身體形狀進行變形，又可穩固地覆蓋穿用者的恥骨周邊，可使在該部位之貼身性提升。Further, in the disposable diaper 1, the portion 11cmin of the reduced diameter portion 11c in which the width of the absorbent core member 11 is narrowed in the left-right direction is the narrowest, and the rigidity in the left-right direction is also the lowest. Further, this portion 11cmin is overlapped with the front side expansion and contraction region 21s (see Fig. 6). Therefore, when the disposable diaper 1 is worn, the portion 11cmin is easily formed as a deformation starting point when the lower abdominal portion 11A of the absorbent core member 11 is raised from the crotch portion toward the lower abdomen side and deformed. In other words, the absorbent core member 11 is easily deformed at the portion 11cmin and is easily floated from the wearer's skin. On the other hand, in the present embodiment, the portion 11cmin having the narrowest width in the left-right direction of the absorbent core member 11 acts on the right and left direction of the front side expansion and contraction region 21s, thereby allowing the floating portion to be lifted. The absorbent core material 11 is pressed against the wearer's skin and is in close contact with each other. Thereby, the absorbent core member 11 can be deformed in accordance with the shape of the wearer's body, and can stably cover the periphery of the pubis of the wearer, and the fit of the wearer can be improved.

又，吸收性芯材11的左右方向之寬度最窄的部位11cmin係在上下方向，設在較中央低基重區域32的下端32ed更上側。如前述般，中央低基重區域32係具有成為使吸收性芯材11在左右方向的中央部凸變形的起點之折彎誘導區域的功能。亦即，在穿用紙尿布1時，在較中央低基重區域32的下端32ed更下側的區域，吸收性芯材11形成變形為朝肌膚側成凸狀的狀態。因此，若在較中央低基重區域32的下端32ed更下側設置部位11cmin的情況，在該部位11cmin，使吸收性芯材11沿著上下方向凸變形之力與配合穿用者的身體形狀而使吸收性本體11從褲襠部朝下腹部立起變形之力相互干涉，使吸收性芯材11變得無法適當地變形之虞。因此，在本實施形態，部位11cmin設在較中央低基重區域32的下端32ed更上側，在部位11cmin的位置所作用的力與在下端32ed的位置所作用的力不會相互干涉。藉此，可容易使吸收性芯材11適當地變形。Moreover, the portion 11cmin having the narrowest width in the left-right direction of the absorbent core member 11 is in the vertical direction, and is provided above the lower end 32ed of the central low-basis weight region 32. As described above, the central low basis weight region 32 has a function as a bending induction region that serves to cause the absorbent core member 11 to be convexly deformed at the center portion in the left-right direction. In other words, when the disposable diaper 1 is worn, the absorbent core member 11 is deformed to be convex toward the skin side in a region lower than the lower end 32ed of the central low basis weight region 32. Therefore, when the portion 11cmin is provided on the lower side of the lower end 32ed of the central low-basis weight region 32, the force of the absorbent core 11 being convexly deformed in the up-and-down direction and the shape of the wearer's body are matched at the portion 11cmin. On the other hand, the force by which the absorbent body 11 is deformed from the crotch portion toward the lower abdomen interferes with each other, and the absorbent core member 11 is prevented from being appropriately deformed. Therefore, in the present embodiment, the portion 11cmin is provided above the lower end 32ed of the central low basis weight region 32, and the force acting at the position of the portion 11cmin and the force acting at the position of the lower end 32ed do not interfere with each other. Thereby, the absorbent core material 11 can be easily deformed appropriately.

以上，說明了關於本發明的實施形態，但前述實施形態係為容易理解本發明之實施形態，並非用來限定本發明。又，本發明在不超出其技術思想範圍下，能夠加以變更、改良等，並且本發明當然亦包含其等價物。The embodiments of the present invention have been described above, but the above embodiments are intended to facilitate the understanding of the embodiments of the present invention and are not intended to limit the invention. Further, the present invention can be modified, improved, etc. without departing from the scope of the technical idea, and the present invention naturally includes equivalents thereof.
