技术领域 FIELD

本发明涉及适合于吸收从女性性器官排泄出的经血等的吸收性物品,特别是涉及覆盖从使用者身体的阴道口到臀部的纵长的吸收性物品。 The present invention relates to an absorbent article suitable for absorbing menstrual blood excreted from the female sex organs and the like, particularly to cover the user's body from the vaginal opening to the longitudinal length of the absorbent article buttocks.

背景技术 Background technique

吸收从女性性器官排泄的经血的吸收性物品的一般结构是具有液体渗透性的顶片、液体非渗透性的底片和液体吸收层;顶片位于皮肤侧表面;底片位于衣服侧表面;液体吸收层介于上述顶片和底片之间,通常,上述底片以通过压敏性粘接层被粘接在内裤的裆布内面的状态使用。 The general structure of the absorbent article from the female genital absorbent excreted menstrual blood is a liquid permeable topsheet, a liquid impermeable backsheet and a liquid absorbent layer; located on the skin side surface of the top sheet; garment side surface of the backsheet located; liquid absorbing layer interposed between the top sheet and the backsheet, typically the backsheet is bonded to the inner surface in the crotch cloth state undergarment through the pressure-sensitive adhesive layer.

这种吸收性物品要求具有以下功能,即,可靠地收集排泄在皮肤侧表面的经血、防止液体从吸收性物品侧漏以及后漏。 Such an absorbent article is required to have a function, i.e., reliably collected menstrual blood is excreted on the skin surface side, to prevent side leakage of the liquid absorbent article and leakage from the rear.

特别是在月经中的女性就寝中使用的吸收性物品要求,防止经血从吸收性物品的横向漏出,并且,使沿着使用者的身体、将要从肛门向着臀沟流出的经血或者沿着吸收性物品的皮肤侧表面将要向后方流动的经血不向外漏出。 Especially women in the menstrual absorbent article for use during sleep requirements, to prevent menstrual blood from leaking transversely of the absorbent article and the user's body along the gluteal groove toward the blood outflow from the anus or along the absorbent skin side surface of the article to the rear of the menstrual blood from leaking outward flow would like. 因此,如特开2001-95842号以及特开2001-129018号所述,就寝时使用的吸收性物品形成为比在白天使用的在纵向更长,在该皮肤侧表面可以覆盖从阴道口的前方的阴阜到肛门的更后方的臀部的广大范围。 Therefore, as-Open No. 2001-95842 and Japanese Patent Laid-Open No. 2001-129018 said absorbent article is formed using at bedtime in the longitudinal direction longer than daytime use, the body surface may be covered from the front of the vaginal opening mons pubis to the anus of a wider range of rear buttocks.

在从对着阴道口的部分一直到对着肛门或臀沟的部分的广大范围上,上述纵长的吸收性物品多使用液体渗透孔均匀地分布的顶片。 In the front part of the vaginal opening until the top sheet against the upper portion of the wide range of the anus or gluteal groove, the vertical length of the absorbent article is often used uniformly distributed liquid penetration hole. 例如,在广大的范围中,顶片使用液体渗透孔均匀地分布形成的无纺布或液体渗透孔均匀地分布的树脂薄膜。 For example, in the vast range topsheet resin film or nonwoven fabric uniformly distributed uniformly distributed liquid permeation holes formed in the liquid permeable pores.

但是,由于上述无纺布形成许多液体渗透孔,所以其表面的摩擦强度降低,因此,如果由于翻身等身体姿势变化,大的力作用于向被臀沟夹住的后方部分,则液体渗透孔的周围的纤维起毛,进而有可能从液体渗透孔的周围产生破裂。 However, since the nonwoven fabric forming a plurality of liquid permeable pores, so the strength of the friction surface decreases, and therefore, if the change in posture due to the turning and the like, a large force is applied to the rear portion clamped gluteal groove, the liquid permeation holes around the fiber fluffing, thereby cracking may occur from the surrounding liquid penetration hole.

另外,在使用形成液体渗透孔的上述树脂薄膜的情况,该树脂薄膜又薄又软的情况下,由于上述姿势的变化,在与肛门或臀沟密合的部分上,容易在顶片上产生褶皱。 Further, in the case where the resin film is formed using the liquid permeable pores, in this case a thin, soft resin film, due to the change of the posture, on a portion or the gluteal anal adhesion easily produce wrinkle in the topsheet . 因此,如上所述,使用薄树脂的情况下,利用热熔粘接剂粘接树脂薄膜和位于其下面的层之间,在下面的层上可以约束树脂薄膜。 Thus, as described above, the case where the thin resin, the use of hot-melt adhesive resin film and the adhesive positioned between the underlying layer, the underlying layer on the resin film may be constrained. 但是,上述热熔粘接剂妨碍经血从顶片向其下层浸透。 However, the above-described hot melt adhesive interfere with the menstrual blood from the top sheet impregnated underlayer thereto.

即,在覆盖从阴道口到臀沟的纵长的吸收性物品中,在对着阴道、一时接受大量经血的前方部分上,要求迅速将经血导向液体吸收层,一方面,对着肛门或臀沟的后方部分要求的不是液体迅速的吸收,而是存留少量的经血、不向外部漏出的效果。 That is, on the cover from the elongated absorbent article of the vaginal opening to the gluteal groove, in front of the vagina, and sometimes accept a large number of front portion menstrual blood, menstrual blood in claim quickly guide the liquid absorbent layer, on the one hand, against the buttocks or the anal rapid absorption of the rear portion of the groove is not a requirement of the liquid, but the remaining small amount of menstrual blood, the effect does not leak to the outside. 在后方部分进一步要求防止由臀沟内的压缩或与臀部的摩擦引起的起毛或破裂,或者阻止褶皱产生程度的耐久性或接合强度。 In the rear portion is further required to prevent fluffing or breakage caused by the compression or friction with the gluteal groove of the buttocks, or to prevent the degree of bonding strength or durability of the wrinkles. 这样,对于覆盖被要求不同功能的各种各样的部分的顶片,使液体渗透孔均匀地分布在上面不是最佳结构。 Thus, for the portion of the topsheet covering a wide variety of different functions are required, the liquid permeation holes are equally spaced on top of the structure is not optimal.

本发明是鉴于上述现有的课题而产生。 The present invention takes the above conventional problem is generated. 因此,本发明的目的是提供以下吸收性物品,即在对着阴道口的前方部分上,可以实现经血渗透的快速性,在对着臀沟的后方部分上,可以提高阻止经血泄漏的功能以及进一步提高表面强度和接合强度。 Accordingly, an object of the present invention to provide an absorbent article, i.e., on the opposite front portion of the vaginal opening, can achieve rapid infiltration of menstrual blood, in front of the gluteal rear portion can be increased to prevent leakage of menstrual blood and functions further improve the surface strength and the bonding strength.

发明内容 SUMMARY

在本发明的第一方面中,提供一种纵长的吸收性物品,具有皮肤侧表面和衣服侧表面,具有位于皮肤侧表面的液体渗透性的顶片、位于衣服侧表面的底片和位于上述顶片和底片之间的液体吸收层,对液体吸收层与顶片一起进行压缩的压缩槽被相对吸收性物品的纵向中心线对称地延伸设置,在其之间形成纵长的中央区域,上述中央区域由前方部分和后方部分构成, In a first aspect of the present invention, there is provided a vertically long absorbent article having a body surface and a garment-facing surface, a top sheet having liquid permeability of the surface located on the skin side, garment-facing surface of the backsheet positioned and located at the a liquid absorbent layer between the topsheet and backsheet, a liquid absorbent layer and the topsheet is compressed together with compression for extending the longitudinal center line of the slot is symmetrically disposed an absorbent article, formed in a longitudinal central region between the the central region is constituted by a front portion and a rear portion,

在上述中央区域,在形成顶片的无纺布上形成液体渗透孔和点状的压花部;液体渗透孔至少贯通上述顶片;点状的压花部至少压缩上述顶片,用(前方部分的液体渗透孔占有的面积总和)/(前方部分的面积)表示的开孔密度高于(后方部分的液体渗透孔占有的面积总和)/(后方部分的面积)的开孔密度,用(后方部分的压花部占有的面积总和)/(后方部分的面积)表示的压花密度高于(前方部分的压花部占有的面积总和)/(前方部分的面积)的压花密度。 In the central region, is formed on the nonwoven fabric forming the top sheet of liquid permeable apertures and embossed portion punctiform; liquid permeation holes through at least said topsheet; dot-shaped embossed portion compressing at least the top sheet, with a (forward aperture area density of the total liquid penetration hole portion occupied) / (the area of ​​the front part) is higher than the (sum of area) / (area of ​​the rear portion) of the rear portion of the liquid permeable pores occupy openings density, with ( embossing the embossed portion of the total area of ​​the density of the rear portion occupied) / (the area of ​​the rear portion) is higher than the (sum of area) / (area of ​​the front portion) of the front portion of the embossed portion occupied embossing density.

该本发明的第一方面的吸收性物品由于顶片由无纺布形成,因此,与使用者身体的接触感觉是软质的。 The absorbent article of the first aspect of the present invention, since the top sheet is formed of a nonwoven fabric, and therefore, the feeling of contact with the user's body is soft. 由于无纺布上形成液体渗透孔的部分是经血靠自重落下而经过上述液体渗透孔内,因此,经血可以迅速渗透。 As part of the liquid penetration hole formed on the nonwoven fabric is dropped by its own weight and blood through said liquid permeable pores, therefore, the menstrual blood can be quickly penetrate. 一方面,在形成在无纺布上的压花部上,纤维密度相当高,可以通过毛细管作用将经血强力吸入。 In one aspect, the embossed portion is formed on the nonwoven fabric, relatively high fiber density, the menstrual blood can be strongly sucked by capillary action. 即虽然液体渗透孔吸引经血的力量弱,但是经血的渗透迅速,虽然压花部经血的渗透速度慢,但是吸引经血的力量强。 That liquid penetration hole to attract the power of blood, although weak, but the rapid penetration of the blood, although the embossed portion blood penetration is slow, but strong draw blood force.

通过在上述中央区域的前方部分上形成许多液体渗透孔,可以将从阴道口排泄的经血短时间地向液体吸收层转移,在后方部分上,可以用压花部拦住从前方部分一点点转移来的经血、防止向外部泄漏。 Many liquid penetration through hole formed in a front portion of the central region, from the vaginal opening can be excreted menstrual blood for a short time to transfer the liquid absorbing layer, on the rear portion, the embossed portion may be stopped a little from the front portion to transfer the blood to prevent leakage to the outside.

并且,通过在后方部分上设置许多压花部,可以提高后方部分的无纺布的表面的摩擦强度,来自臀沟的力被向后方部分施加时,可以防止起毛或产生破裂等。 Further, by providing a number of embossed portions in the rear portion, the strength of the nonwoven fabric can be improved friction surface of the rear portion, the force is applied from the gluteal rearward portion, generation of cracks can be prevented from fluffing or the like. 另外,由于前方部分压花部的数量少,因此,压花部接触到阴道口等的概率低,在前方部分上,对阴道口等的刺激减少,成为穿着感良好的部分。 Further, since the number of the front portion of the embossed portion, therefore, embossed portions in contact with the vaginal opening to the low probability or the like, in the front portion, stimulation of the vaginal opening and the like is reduced, to become a good sense of wearing parts.

另外,本发明的第一方面的吸收性物品可以构成为,上述顶片含有热粘接性纤维,在上述顶片的下面设置有含有热粘接性纤维的第二层,上述液体渗透孔从上述顶片到上述第二层形成,在上述液体渗透孔的内面,顶片和第二层被热粘接,在上述压花部,上述顶片和上述第二层被一起压缩,并且被热粘接。 Further, the absorbent article of the first aspect of the present invention may be arranged such that the top sheet comprises heat-fusible fiber, the lower surface of the top sheet is provided with a second layer, the pores containing the liquid permeation from the heat-fusible fiber said top sheet to said second layer is formed, the liquid permeable inner surface of the hole, the top sheet and the second layer are thermally bonded, in the embossed portion, the top sheet and said second layer are compressed together, and thermally bonding.

这种情况下,由于顶片和第二层在液体渗透孔的周围被粘接,因此,顶片被第二层加固,在受到来自使用者身体的力时,不容易在表面层产生褶皱,可以防止在顶片从液体渗透孔的部分开始产生破裂。 In this case, since the top sheet and the second layer is adhered to the liquid penetration surrounding the hole, and therefore, the top sheet is reinforced second layer, when subjected to a force from the user's body, is not prone to wrinkles in the surface layer, generation of cracks can be prevented from the beginning portion of the liquid permeable topsheet hole. 因此,也可以将上述液体渗透孔形成大的开口尺寸。 Thus, the liquid permeability may be formed in a large hole opening size. 另外,在后方部分上,如果形成顶片和第二层被一起压缩的压花部,则在后方部分上,顶片也被第二层加固。 Further, in the rear portion, by forming the embossed portion and the topsheet is compressed together with the second layer, on the rear portion, the top sheet is also a second reinforcing layer. 并且,如果一起压缩顶片和第二层,则压花部的周围蓬松,压花部不容易使使用者的身体有硬质感。 And, if the compression along the topsheet and a second layer, the embossed peripheral portion fluffy, embossed portion is not easy to the user's body has a hard texture.

如上所述,为了发挥加固功能并且形成蓬松,上述第二层的单位面积重量最好大于上述顶片的单位面积重量。 As described above, in order to exhibit the reinforcing function and form fluffy, basis weight of the second layer is preferably greater than the basis weight of the topsheet.

另外,本发明的第一方面的吸收性物品可以构成为在上述前方部分上形成有上述液体渗透孔,但不形成上述压花部。 Further, the absorbent article of the first aspect of the present invention may be configured to have the liquid penetration hole formed in the front portion, but not the formation of the embossed portion.

通过在前方部分上只形成液体渗透孔,整个前方部分的区域成为软质的,对阴道口或其周边的密合感觉是软质的、且感觉良好。 By forming only the liquid permeation holes in the front portion, the front portion of the entire region to become soft on the outside of the vaginal opening or its adhesion feeling is soft, with a good feeling.

这种情况下,在上述后方部分上邻接的上述压花部的中心间距离的平均值最好大于上述前方部分上邻接的上述液体渗透孔的中心间距离的平均值。 In this case, the average distance between adjacent rear portion on the center of the embossed portion is preferably greater than the average distance between the centers of adjacent penetration holes of the liquid on said front portion.

通过在前方部分提高液体渗透孔的开孔密度,可以将从阴道口排泄的经血迅速从上述液体渗透孔向液体吸收层转移。 Increased density liquid penetration through the opening hole in a front portion, from the vaginal opening can rapidly absorb menstrual blood excreted layer is transferred to the liquid from the liquid permeable pores. 另外,由于要向后方部分转移的经血比排泄在前方部分上的经血少,因此,即使压花密度低,也可以充分阻止向后方的转移。 Further, since the blood would like to transfer rearward portion than in the front portion of the drain less blood, and therefore, even if the embossing is low density, transfer can be sufficiently prevented rearward. 另外,通过降低后方部分上的压花密度,可以防止后方部分过硬,可以使与使用者身体的接触感觉柔软。 Further, by decreasing the density of the embossing on the rear portion, the rear portion can be prevented from perfect, can make contact with the user's body feels soft.

在本发明的第二方面中,提供一种纵长的吸收性物品,具有皮肤侧表面和衣服侧表面,具有位于皮肤侧表面的液体渗透性的顶片、位于衣服侧表面的底片和位于上述顶片和底片之间的液体吸收层,对液体吸收层与顶片一起进行压缩的压缩槽被相对吸收性物品的纵向中心线对称地延伸设置,在其之间形成纵长的中央区域,上述中央区域由前方部分和后方部分构成,在整个上述中央区域上,液体渗透孔均匀地分布在顶片上,上述顶片被压缩的点状的压花部被设置在上述中央区域,使得用(后方部分的压花部占有的面积总和)/(后方部分的面积)表示的压花密度高于(前方部分的压花部占有的面积总和)/(前方部分的面积)的压花密度。 In a second aspect of the present invention, there is provided a vertically long absorbent article having a body surface and a garment-facing surface, a top sheet having liquid permeability of the surface located on the skin side, garment-facing surface of the backsheet positioned and located at the a liquid absorbent layer between the topsheet and backsheet, a liquid absorbent layer and the topsheet is compressed together with compression for extending the longitudinal center line of the slot is symmetrically disposed an absorbent article, formed in a longitudinal central region between the the central region is constituted by a front portion and a rear portion, on the whole the central region, the liquid permeation holes are evenly distributed over the topsheet, dot-shaped embossed portion of the top sheet to be compressed is provided in the central region, so that a (rearward embossing density of the sum of the areas occupied by the embossed portion) / (area of ​​the rear portion) is higher than the (sum of area) / (area of ​​the front portion) of the front portion of the embossed portion occupied embossing density.

该本发明的第二方面的吸收性物品通过主要在后方部分设置压花部,压花部不对阴道口及其周边进行刺激。 The absorbent article of the second aspect of the present invention is mainly provided by the rear portion of the embossed portion, the embossed portion does not stimulate the vaginal opening and its surroundings. 并且,用密度高的压花部可以吸引要向后方转移的经血。 Further, the high density portion can be embossed backward To attract blood transfer.

在本发明的第二方面中,顶片不局限于由无纺布形成,形成液体渗透孔的树脂薄膜也可以。 In a second aspect of the present invention is not limited to the topsheet formed from a nonwoven fabric, a liquid permeable pores are formed may be a resin film.

这种情况下,通过上述压花部可以使顶片及其下面层的接合性良好,可以防止由于与臀沟等的摩擦在顶片上产生的褶皱。 In this case, the bonding of the topsheet and the underlying layer is good by the embossing portion, wrinkles can be prevented due to the friction generated by the gluteal groove and the like on the topsheet. 另外,通过压花提高顶片的下面层的密度,在该密度高的部分上可以发挥存留将要向后方转移的经血的功能。 Further, by increasing the density of the embossing layer below the topsheet, menstrual blood can be retained behind the play To transfer function in the high density portion.

在上述树脂薄膜的顶片的下面设置有含有热粘接性纤维的第二层,在上述压花部,上述顶片和上述第二层最好被一起压缩、热粘接。 Below the top sheet of the resin film is provided with a second layer in the embossing portion, the top sheet and said second layer are preferably compressed together, comprising heat bonding the heat-fusible fiber.

这样,在后方部分上,不用过多地使用热熔粘接剂就可以将树脂薄膜的顶片和第二片一体化,并且,在压花部可以提高第二层的纤维密度,可以用压花部强力地吸收经血。 Thus, in the rear portion, without excessive use of hot-melt adhesive resin sheet may be a top film and a second sheet integration, and, in the embossed portion can be increased fiber density of the second layer, with a press floral strongly absorbed by blood.

另外,如果使吸收性物品成为在上述前方部分上不形成上述压花部的结构,则前方部分与阴道口及其周边密合时,可以减少对使用者皮肤的刺激。 Further, if the absorbent article does not become embossed structure is formed on the portion of the front portion, the front portion of the vaginal opening and its surroundings interferes with the seal, may reduce irritation to the skin of the user.

如上所述,本发明适用于上述前方部分与使用者的阴道口的区域相对,上述后方部分与上述阴道口以外的后方部分的区域相对的纵长的吸收性物品。 As described above, the present invention is applied to the front portion of the user's vaginal opening opposing area, the area behind the rear portion other than the portion above the vaginal opening opposing elongated absorbent article.

上述顶片3含有可以进行熔融结合的热可塑性纤维,上述第二层5也含有可以进行熔融结合的热可塑性纤维。 Comprising the top sheet 3 may be fusion-bonded thermoplastic fibers, the second layer 5 can also contain fusion bonding thermoplastic fibers. 在此,顶片3和第二层5不应被局限、解释为是只由这样的热可塑性纤维形成的片/层,也可以是除热可塑性纤维以外,含有象天然纤维或再生纤维素纤维的非热可塑性纤维的片/层。 Here, the top sheet 3 and the second layer 5 is not to be limited, is interpreted as a sheet / layer is formed only by such thermoplastic fibers, may be in addition to the thermoplastic fibers, natural fibers or the like comprising regenerated cellulose fibers non-thermoplastic fibers of the sheet / layer.

上述液体渗透孔25通过加热的针或销钉形成。 The liquid permeable pores 25 formed by a heated needle or pin. 即,在顶片3和第二层5被重叠的状态下,通过将上述针或销钉从顶片3向第二层5侧插入、拔出,形成末端25a向下侧突出形状的液体渗透孔25。 That is, in the top sheet 3 and the second layer 5 is stacked state, by inserting the needle or pin 3 from the top sheet side toward the second layer 5, pulled out to form a liquid permeable pores terminal 25a projecting downward shape 25. 此时,在液体渗透孔25的内面25b及其周围,顶片3中含有的热可塑性纤维与第二层5中含有的热可塑性纤维被相互热粘接。 In this case, the liquid permeable inner surface 25b of the hole 25 and around the thermoplastic fibers thermoplastic fibers contained in the top sheet 3 and the second layer 5 is contained in the thermally bonded to each other. 这样,可以维持液体渗透孔25的开孔形状,并且通过第二层5,液体渗透孔25的开孔周围被加固。 Thus, it is possible to maintain the shape of the liquid permeable pores 25 opening, and by a second layer 5, around the opening 25 of the liquid penetration hole is reinforced. 另外,由于顶片3和液体渗透层5被熔融结合,因此,没有必要用粘接剂粘接顶片3和第二层5,不会发生粘接剂妨碍液体渗透的情况。 Further, since the top sheet 3 and the liquid permeable layer 5 is bonded melted, therefore, no need to use adhesive bonding the topsheet 3 and the second layer 5, the adhesive does not occur prejudice to liquid penetration.

上述液体渗透孔25形成后,顶片3和第二层5被夹在经过加热的滚之间,形成上述压花部26。 After the liquid permeation holes 25 are formed, a top sheet 3 and the second layer 5 is sandwiched between the heated roll, the embossing portion 26 is formed. 此时,表面平坦的滚接触第二层5的表面,具有凸部的压花滚接触顶片3的表面。 At this time, the rolling surface of the flat contact surface of the second layer 5 having a rolling surface of the embossing convex portion 3 is in contact with the topsheet. 这样,在压花部26的内面26b上,顶片3中含有的热可塑性纤维与第二层5中含有的热可塑性纤维被相互热粘接,同时,在该内面26b的外周部分上,顶片3和第二层5的纤维密度增高。 Thus, the inner surface 26b embossed portion 26, thermoplastic fibers thermoplastic fibers topsheet 3 contained in the second layer 5 contained are welded to each other, while, on the outer peripheral portion of the inner face 26b, the top fiber density layer 5 and the second sheet 3 is increased.

在压花部26的底部26a上,形成顶片3的纤维和形成第二层5的纤维被压缩、形成高密度,上述热可塑性纤维熔化,底部26a成为薄膜状或几乎薄膜状。 On the bottom 26a of the embossed portion 26 to form a fiber forming the topsheet 3 and the fibers of the second layer 5 is compressed, high density, melting the thermoplastic fibers, the bottom 26a become almost film-like or film-like.

通过内面26b和底部26a上的热可塑性纤维的热粘接,可以保持压花部26的形状,并且,通过第二层5可以加固顶片3。 Thermoplastic fibers by thermal bonding on the inner bottom face 26b and 26a, can maintain the shape of the embossed portion 26, and the second layer 5 by a solid top sheet 3 may be added. 特别是由于底部26a被形成高密度,可以提高顶片3的耐久性。 In particular, since the bottom 26a is formed a high density, can improve the durability of the topsheet 3.

上述顶片3由热风无纺布形成。 The top sheet 3 is formed by a hot-air nonwoven fabric. 该热风无纺布使用芯部为含有氧化钛的聚对苯二甲酸乙二酯(PET),外皮为聚乙烯(PE)的芯鞘型复合合成纤维,通过热风将该纤维粘接而成,单位面积重量为15~60g/m2左右。 The hot-air nonwoven fabric used for the core part containing titanium oxide of polyethylene terephthalate (PET), the sheath of polyethylene (PE) core-sheath type composite synthetic fibers, bonding the fibers together by hot air, basis weight of about 15 ~ 60g / m2. 另外,构成顶片3的上述复合合成纤维中的一部分涂敷有亲水性界面活性剂,其余的涂敷有防水性界面活性剂,这些纤维被混合,涂敷有防水性界面活性剂的纤维的混合率最好为10~30质量%。 Further, the coating part of the composite synthetic fibers constituting the top sheet 3 hydrophilic surfactant, the remaining coated with water-repellent surfactant, the fibers are mixed, fibers coated with water repellent surfactant the mixing ratio is preferably from 10 to 30 mass%. 通过使顶片3均匀地含有涂敷有防水性界面活性剂的纤维、形成上述范围的混合率,可以抑制排泄到顶片3的经血在顶片3内过于扩散,使经血在前方部分20A上主要渗透液体渗透孔25、排泄到液体吸收层4。 By the top sheet 3 is uniformly coated with water repellent fiber comprising surfactant to form a mixture of the above-described range can suppress menstrual blood excreted topsheet 3 is excessively diffused in the top sheet 3, menstrual blood in front of the main portion 20A infiltration liquid penetration holes 25, liquid absorbent layer 4 into the drain.

但是,上述顶片3也可以在液体渗透孔25以外的区域使经血向着第二层5渗透。 However, the top sheet 3 may be liquid permeable region other than the hole 25 of the menstrual blood toward the second permeable layer 5. 顶片3为了发挥这样的液体渗透功能,密度最好小于等于0.12g/cm3,其下限为0.025g/cm3左右。 In order to exert such a topsheet 3 liquid permeation function, preferably less density 0.12g / cm3, the lower limit is about 0.025g / cm3.

第二层5是由芯部为聚丙烯(PP)、外皮为聚乙烯(PE)的剖面为偏心形状的芯鞘型复合合成纤维形成的热风无纺布形成。 The second layer 5 by the hot air core portion of polypropylene (PP), the sheath of polyethylene (PE) cross-sectional shape of an eccentric core-sheath type composite synthetic fibers of the nonwoven fabric. 第二层5的热风无纺布是所有的纤维都被亲水性界面活性剂进行涂敷。 Hot-air nonwoven fabric 5 of the second layer are all of the fibers are coated hydrophilic surfactant. 即不含有涂敷了防水性界面活性剂的纤维。 I.e., containing no water-repellent coated fiber surfactant. 在图3和图4所示的实施方式中,第二层5由将多张上述热风无纺布重叠构成,例如,将一张热风无纺布折叠成三层进行使用。 In the embodiment shown in FIG. 3 and FIG. 4, the second layer 5 is constituted by a plurality of superimposed above air bonded nonwoven fabric, for example, an air-through nonwoven use be folded in three. 一张热风无纺布的单位面积重量为15~50g/m2左右,第二层5的单位面积重量为45~150g/m2左右。 A hot-air nonwoven fabric basis weight of about 15 ~ 50g / m2, basis weight of the second layer 5 is about 45 ~ 150g / m2.

通过使第二层5的单位面积重量大于顶片3的单位面积重量,可以用第二层5加固顶片3,可以防止在顶片3上产生过大的褶皱、从液体渗透孔25的部分产生破裂等。 By weight of the second layer 5 is greater than the basis weight of the topsheet 3, the second layer 5 can be applied with a solid top sheet 3 can be prevented from excessive wrinkles on the top sheet 3, the liquid portion from the permeable hole 25 produce rupture.

例如,顶片3由细度为2.2dtex的纤维构成,第二层5由细度为4.4dtex的纤维构成。 For example, the topsheet 3 is made of fibers having a fineness of 2.2dtex, the second layer 5 is a fiber fineness of 4.4dtex configuration. 第二层5的纤维密度低于顶片3的纤维密度。 The fiber density of the second layer 5 is less than the fiber density of the topsheet. 第二层5的纤维密度为0.016~0.08g/cm3。 The fiber density of the second layer 5 is 0.016 ~ 0.08g / cm3.

另外,顶片3和第二层5也可以由上述热风无纺布以外的无纺布形成。 Further, the topsheet 3 and the second layer 5 may be formed of a nonwoven fabric other than the air-through nonwoven. 例如,可用射流喷网无纺布形成顶片3,该射流喷网无纺布由再生纤维素纤维和熔融结合性的热可塑性纤维,而且如果需要加入纸浆构成,可以用气流成网无纺布形成第二层5,气流成网无纺布是将纸浆和热可塑性纤维在空气中层积后用粘接剂粘接、在加热辊之间加压。 For example, spunlaced nonwoven fabric can be used form the top sheet 3, the spunlaced nonwoven fabric from recycled fibers and thermoplastic binding fibers melt cellulose and, if desired added to the pulp composition, the nonwoven fabric may be airlaid with forming a second layer 5, airlaid nonwoven fabrics is a pulp and thermoplastic fibers in the middle air volume after the adhesive bonding, the pressure between the heating roller.

上述液体吸收层4是在粉碎纸浆、碱化纸浆、交联纸浆等的纸浆的聚合体中含有聚丙烯酸盐、聚丙烯酰胺、无水马来酸等的合成吸水聚合物或淀粉、纤维素等天然类的吸收聚合物的材料,将纸浆以及上述合成吸水聚合物等用亲水性的薄纸包住使用。 Starch or a synthetic polymer water-absorbing polymer of the liquid absorbing layer 4 is ground pulp, mercerized pulp, cross-linked pulp or the like contained in pulp polyacrylates, polyacrylamides, maleic anhydride, etc., and cellulose absorbing polymer material of natural origin, synthetic pulp and said water-absorbing polymer with a hydrophilic tissue wrap used.

上述底片2是液体非渗透性的并且是透气性的薄片,是形成有细微的透气孔的聚乙烯(PE)薄膜或聚丙烯(PP)薄膜等。 2 described above is a liquid impermeable backsheet and the breathable sheet, is formed with fine holes of the polyethylene (PE) film or polypropylene (PP) film. 例如,通过向塑料薄片上混合CaCO3、BaSO4等无机填充物、进行延伸处理,细微的透气孔在薄膜上适当地分散形成,提高了通气性。 For example, by mixing CaCO3, BaSO4 inorganic filler onto a plastic sheet, extends process, dispersing fine holes are formed on the film is suitably, improving the air permeability. 薄膜的厚度为15~50μm左右。 Thickness of the film is about 15 ~ 50μm.

上述第二层5和吸收层4用热熔粘接剂粘接,热熔粘接剂被不妨碍液体渗透地进行部分涂抹。 Said second absorbent layer 5 and the layer 4 with hot melt adhesive bonding, hot melt adhesive is performed does not interfere with the liquid permeable portion of the application. 另外,液体吸收层4和底片2也用热熔粘接剂粘接。 Further, the liquid absorbent layer 4 and the backsheet 2 also melt adhesive adhesive.

在该生理用卫生巾1的制造工序中,如上所述,将顶片3和第二层5重叠,将液体渗透孔25和压花部26任何一个先形成,然后粘接液体吸收层4和第二层5、形成上述压缩槽10。 In the manufacturing process of the sanitary napkin 1, as described above, the top sheet 3 and the second layer 5 overlaps the first form 26 of any liquid penetration hole 25 and the embossed portion, and an adhesive layer 4 and the liquid absorbent a second layer 5, the compressed groove 10 is formed. 然后,将底片2与液体吸收层4的表面粘接。 Then, the liquid surface of the backsheet 2 and the adhesive layer 4 is absorbed.

如图2所示,在皮肤侧表面的左右两侧设置非渗透性片30、30。 As shown in FIG. 2, the impermeable sheet 30, 30 arranged at both sides of the left and right side surfaces of the skin. 在上述侧翼1A、1A以及后部襟翼1B、1B上,上述非渗透性片30、30被热熔粘接剂粘接在底片2的上面。 In the side flaps 1A, 1A and a rear flap 1B, on 1B, the non-permeable sheet 30, 30 is hot melt adhesive film 2 is adhered to the top. 在从纵向中心线Oy-Oy向左右等距离离开的位置上,非渗透性片30被重叠成两层,纵向延伸的弹性部件32被粘接在其内部。 At a position apart equidistant from the longitudinal centerline Oy-Oy on the right and left, non-permeable sheet 30 are overlapped in two layers, longitudinally extending elastic member 32 is adhered to the inside thereof. 通过上述弹性部件32,弹性收缩力作用在生理用卫生巾1的前方部分和后方部分之间,使生理用卫生巾1弯曲,其结果,在生理用卫生巾1的前后的中间部分上,非渗透性片30、30立起、形成防漏壁31、31。 By the elastic member 32, an elastic contractive force acting between the front portion and the rear portion of the sanitary napkin 1, the sanitary napkin 1 is bent, as a result, in the intermediate portion of the front and rear of the sanitary napkin 1, the non- permeability raised pieces 30, 31, 31 forming the leakage preventing wall.

上述非渗透性片由纺粘形无纺布、熔喷无纺布或层积这些无纺布的复合无纺布形成。 Said non-permeable sheet-shaped spunbond nonwoven fabric, meltblown nonwoven fabric or a composite nonwoven fabric laminate of these nonwoven fabric.

液体吸收层4的单位面积重量在中央区域20上为最大。 Weight of the liquid absorbing layer 4 in the central region 20 is maximum. 被内侧压缩槽11、11和前方外侧压缩槽15、15夹住的部分、被内侧压缩槽11、11和后方外侧压缩槽16、16夹住的部分以及被后方连接压缩槽14和后方连接压缩槽17夹住的部分的各个的单位面积重量都小于上述中央区域20。 11 and 11 are compressed and the outer front of the inner compressed grooves 15, 15 sandwiching the groove portion, the outer portions 11, 11 is clamped and the rear inner compressed grooves 16, 16 and a connecting groove compression compresses the rear connecting compressed groove 14 and a rear each weight per unit area of ​​the groove portions 17 sandwiched between the central region are smaller than 20. 这些部分以外的液体吸收层4的部分的单位面积重量与被内侧压缩槽11、11和前方外侧压缩槽15、15夹住的部分等相同或稍小。 Weight of the liquid absorbent layer portions other than these portions 4 and the outer portions 11, 11 and the like are compressed in front of the inner compressed grooves 15, 15 sandwiching the groove of the same or slightly smaller.

在中央区域20上的液体吸收层4的理想的单位面积重量为400~1200g/m2,最好是500~1000g/m2。 Weight of the liquid in the central region 20 of the absorbent layer 4 is over 400 ~ 1200g / m2, preferably 500 ~ 1000g / m2. 被上述内侧压缩槽11、11和前方外侧压缩槽15、15夹住的部分、被内侧压缩槽11、11和后方外侧压缩槽16、16夹住的部分以及被后方连接压缩槽14和后方连接压缩槽17夹住的部分的各个理想的单位面积重量最好为300~900g/m2,更好是350~600g/m2。 The outside of the inner compressed grooves 11 and compression slots 15 sandwiched between the front portion, the outer portions 11, 11 is clamped and the rear inner compressed grooves 16, 16 and a compressed groove is connected behind the compressed groove 14 and the rear connector over the weight of the respective portions of the compressed groove 17 is preferably sandwiched between 300 ~ 900g / m2, more preferably 350 ~ 600g / m2. 另外,其他部分的液体吸收层4的理想的单位面积重量为300~700g/m2。 Further, other portions of the liquid absorbing layer over the weight of 4 to 300 ~ 700g / m2.

其结果,如图2所示,在中央区域20上厚度增大,在中央区域20上,皮肤侧表面成为向着使用者身体膨胀成很大的形状。 As a result, as shown in Figure 2, an increase in the thickness of the central region 20, central region 20 on the skin side surface becomes large toward the user's body is expanded into a shape.

中央区域20的长度,即前方连接压缩槽12和后方连接压缩槽14的纵向的间隔为120~300mm左右。 Length of the central region 20, i.e., the front and rear connecting compressed groove 12 spaced longitudinally connecting the compressed groove 14 is about 120 ~ 300mm. 图2所示的横向基准线Ox-Ox上的中央区域20的宽度、即在前方部分20A最狭窄的宽度W1上根据女性生殖器的宽度而确定。 Width of the central region 20 on the lateral reference line Ox-Ox in FIG. 2, i.e., to determine the most narrow in the width W1 to the width of the front portion 20A of the female genitalia. 由于女性的大腿根部间的平均宽度为30mm左右,因此上述宽度W1最好在15~50mm的范围,20~40mm的范围更好。 Since the average width between thigh female is about 30mm, and therefore the above-described width W1 preferably in the range of 15 ~ 50mm, more preferably in the range of 20 ~ 40mm. 另外,内侧压缩槽11、11的弯曲部11B、11B之间的横向距离比上述宽度W1宽10~40mm左右。 The inner compressed grooves 11, 11 of the bent portions 11B, 11B between the left and right lateral distance than the width W1 width 10 ~ 40mm. 另外,第二层5的侧边缘部5a、5a之间的宽度比上述宽度W1窄1~10mm。 Further, 5a, 5a of the second layer width between the side edge portions 5 1 ~ 10mm is narrower than the width W1.

中央区域20的上述后方部分20B是容易进入如图6所示的女性的臀沟(Q)的尺寸,其长度,即从弯曲部11B、11B到后方连接压缩槽14的长度为60~150mm左右。 The rear portion 20B of the central region 20 shown in FIG. 6 is easy to enter the gluteal groove of the female (Q), the size, the length, i.e., from the bent portion 11B, 11B connected to the rear compression longitudinal groove 14 is approximately 60 ~ 150mm .

将该生理用卫生巾1用于使用者的身体上时,将设置在底片2的外面的压敏粘接剂与图2所示的裆布41的内面粘接,此时,后部襟翼1B、1B也与内裤的内面粘接。 The sanitary napkin 1 on the wearer's body when used, will be disposed in the crotch cloth bonding the inner surface 41 of the backsheet 2 outside as shown in FIG. 2 and the pressure-sensitive adhesive, at this time, the rear flap 1B, 1B but also the inner surface of the undergarment adhesive. 另外,将侧翼1A、1A向着内裤的外面弯曲、卷住裆布41的两侧边缘部,将设置在侧翼1A、1A的衣服侧表面的压敏粘接剂粘接在裆布41的外面。 Further, the flaps 1A, 1A is bent toward the outside of the undergarment, Juanzhu crotch portion 41 of the side edges of the cloth will be disposed in the flank 1A, outside the pressure-sensitive adhesive bonding of the garment-facing surface 1A of the crotch cloth 41.

如图6所示,将生理用卫生巾1安装在裆布41上的状态下穿上该内裤后,女性的大腿根中间部从阴阜(M)到臀沟(Q)被生理用卫生巾1的皮肤侧表面覆盖。 6, the sanitary napkin 1 in a state mounted on the crotch cloth 41 after wearing the undergarment, the intermediate portion of the thigh of female physiology from the mons pubis (M) to the gluteal fold (Q) napkin skin side surface 1 is covered.

如图2所示,被内侧压缩槽11和11夹住的中央区域20向着使用者的身体膨胀,比其他部分更加蓬松。 As shown in FIG. 2, 11 and 11 are sandwiched between the inner compressed groove 20 toward the central region of the wearer's body expansion, fluffier than other parts. 因此,蓬松的中央区域20的前方部分20A容易与阴道口(N)密合,最好是横向基准线Ox-Ox穿过的部分与阴道口(N)的中心部密合。 Thus, the central front region 20 fluffy readily vaginal opening portion 20A (N) adhesion, preferably a lateral reference line Ox-Ox passing through the vaginal opening portion (N) of the central portion of the adhesion. 另外,被内侧压缩槽11、11的弯曲部11B、11B夹住的宽的部分主要与会阴部(O)接触,中央区域20的后方部分20B与肛门(P)到臀沟(Q)接触。 Further, the inner portion of the curved portion 11B of the compressed grooves 11, 11, 11B sandwiched wide main perineum (O) in contact with the rear portion 20B anus (P) to the central region 20 of the gluteal groove (Q) in contact.

位于上述中央区域20的皮肤侧表面的顶片3是低密度的热风无纺布,在其下面设置有蓬松的热风无纺布第二层5。 A top sheet located on the skin side surface of the central region 20 of low density air-through nonwoven 3 is provided with a hot-air nonwoven fabric bulky second layer 5 thereunder. 因此,中央区域20给予使用者身体的上述各部分的接触感觉是柔软的。 Thus each of the contact portions, the central region 20 giving the user a feeling of the body is flexible. 特别是,由于在前方部分20A上不存在压花部26,因此压花部不接触阴道口及其周边,不会感到刺激。 In particular, since the embossed portion 26 is not present on the front portion 20A, thus embossed portions does not contact the vaginal opening and its surroundings, without irritation. 另外,由于位于后方部分20B的压花部26向第二层5深陷,因此在后方部分20B上,压花部26的底部26a的高密度部分很难与使用者的身体直接接触。 Further, since the embossed portion located rearward portion 20B of the second layer is 5 to 26 deep, so the rear portion 20B, the high density portion of the body of the user is difficult to emboss the base portion 26 of the direct contact 26a. 因此,降低了压花部26刺激会阴部(O)、肛门(P)以及臀沟(Q)内的可能性。 Thus, the likelihood of irritation in the embossed portion 26 perineum (O), anal (P) and gluteal groove (Q).

从阴道口(N)排泄出的经血主要被排泄在中央区域20的前方部分20A上。 Excreted from the vaginal opening (N) menstrual blood is excreted primarily in the front portion 20A of the central region 20. 由于顶片3是低密度的无纺布,经血虽然向顶片3内渗透,但是由于顶片3含有涂敷了防水性界面活性剂的纤维,因此,在顶片3上的经血的扩散被阻止。 Since the topsheet is low density nonwoven fabric 3, although the penetration of blood into the top sheet 3, but since the top sheet 3 comprises fibers coated with water-repellent surfactant, and therefore, the menstrual blood diffused in the sheet is 3 prevent. 排泄在顶片3上的经血向与顶片3下面密合的第二层5上转移,由于第二层5是热风无纺布,在内部具有空隙,因此,经血靠重力经过第二层5的空隙内,被位于其下面的液体吸收层4吸引。 Transfer the excretion of menstrual blood on the top sheet 3 and the top sheet 3 to the following adhesion of the second layer 5, since the second nonwoven fabric layer 5 is hot air, having a void inside, therefore, the menstrual blood by gravity through the second layer 5 in the space, which is located below the liquid absorbing layer 4 suction. 但是,被排泄到前方部分20A上的大多数经血迅速通过液体渗透孔25内,被与第二层5的下面密合的液体吸收层4吸引。 However, most of the menstrual blood is excreted into the front portion 20A rapid liquid penetration hole 25 is below the liquid layer 4 and 5 is attracted adhesion absorbed by the second layer.

这样,从阴道口(N)排泄出的经血在前方部分20A上被液体吸收层4迅速吸收。 In this way, excreted from the vaginal opening (N) in the front portion 20A menstrual blood is rapidly absorbed liquid absorbing layer 4. 但是,以就寝时的姿势,存在着要越过身体的会阴部(O)向着肛门(P)以及臀沟(Q)流动的经血。 However, in order to posture when sleeping, there to cross the body of the perineum (O) toward the anus (P) and the gluteal fold (Q) flow of blood. 另外,大量的经血被一次向前方部分20A排泄时,有时其一部分沿着顶片3的表面向后方部分20B转移。 Further, when a large amount of menstrual blood is excreted forward portion 20A, 20B may transfer a portion of its rearward portion along the surface of the top sheet 3.

向上述后方部分20B转移的经血通过压花部26的周围的高密度部分的毛细管作用,被强力吸引,但是由于该高密度部分是从顶片3到第二层5形成,因此,经血沿着高密度部从顶片3到第二层5、被在其下面的高亲水性的液体吸收层4吸入、保持。 The rear portion 20B to transfer the menstrual blood by the capillary action of the high density portion 26 of the periphery of the embossed portions, is strongly attracted, but due to the high density portion formed from the top sheet 3 to the second layer 5, and therefore, the menstrual blood along the high density portion from the top sheet 3 to the second layer 5, high hydrophilicity is its liquid absorbing layer 4 below the suction holding. 虽然在后方部分20B上不形成液体渗透孔25,但由于到达该后方部分20B的经血的量比排泄在前方部分20A上的经血少得多,因此通过散布在后方部分20B上的压花部26可以充分收集要向后方流动的经血。 Although liquid penetration holes are not formed in the rear portion 20B 25, but due to the menstrual blood arrives at the rear portion 20B than at the front portion 20A of excretion of menstrual blood is much less, thus embossed portions spread by the rear portion 20B 26 To collect menstrual blood can be fully behind the flow. 因此,可以防止经血向后方的泄漏。 Thus, menstrual blood can be prevented from leaking backward.

在此,上述后方部分20B与从肛门(P)到臀沟(Q)内密合,对应臀部的活动、来自侧方的压缩力反复作用于上述后方部分20B。 Here, the rear portion 20B and the anus (P) to the gluteal fold adhesion (Q), corresponding to the activities of the hip, the compression force is repeatedly applied from the side to the rear portion 20B. 另外,由于象就寝时翻身那样的身体姿势的大的变化,压力也作用于上述后方部分20B,并且该压力发生变化。 Further, due to the large change in body posture such as a turn as at bedtime, pressure acting on the rear part 20B, and the pressure change. 但是,通过设置压花部26,在后方部分20B上,顶片3的耐久性被提高,并且,顶片3被第二层5加固。 However, 26 in the rear portion 20B, the durability of the top sheet 3 is increased by providing the embossed portion, and the top sheet 3 by a second reinforcement layer 5. 因此,可以消除在后方部分20B上产生大的褶皱或者表面起毛,进而产生破损的不安。 Thus, it is possible to eliminate a large surface of the pleats or fluff, and further unrest in the rear portion broken 20B.

图5是说明本发明的其他实施方式的生理用卫生巾的部分俯视图。 FIG 5 is a diagram illustrating another embodiment of a physiological embodiment of the present invention with a plan view of the portion of the sanitary napkin.

在图5中只表示了包括压缩槽11至17以及中央区域20和第二层5的部分。 FIG. 5 shows only the portion comprises compressed grooves 11 and 17 and a central region 20 and the second layer 5. 其他部分由于与图1所示的第一实施方式的生理用卫生巾1相同,因此省略了图示。 Other parts of the same due to the physiological aspect of the first embodiment shown in FIG. 1, the sanitary napkin 1, and therefore not shown. 另外,图5所示的压缩槽11至17的形状和结构与图1所示的第一实施方式相同。 Further, the same compression slot shown in Figure 5 11-17 shape and configuration of the first embodiment shown in FIG. 1 embodiment.

如图5所示(如在图1的实施方式中也进行说明的),被内侧压缩槽11、11、前方连接压缩槽12以及后方连接压缩槽14围住的中央区域20是以弯曲部11B、11B为起点,其更前方为前方部分20A,以弯曲部11B、11B为起点,其更后方为后方部分20B。 5 (as also in the embodiment illustrated in FIG. 1), the inner compressed grooves 11, 12 and the front connecting compressed groove connected to the rear central region 20 of the compressed groove 14 is surrounded bent portion 11B , 11B as a starting point, it is more forward as the front portion 20A, the curved portion. 11B, 11B as a starting point, it is more rearward of rear portion 20B. 并且,在本实施方式中,前方部分20A进一步具有三个区域,即,第一前方部分20A1、第一前方部分20A1的更前方的第二前方部分20A2以及第一前方部分20A1的更后方的第三前方部分20A3,在此,第一前方部分20A1与第二前方部分20A2的交界和第一前方部分20A1与第三前方部分20A3的交界是从横向基准线Ox-Ox向纵向离开等距离。 Further, in the present embodiment, the front portion 20A further has three regions, i.e., the first portion 20A1, a more rearward portion of the first front of the first front of the second front portion further forward 20A1 and 20A2 of the first front portion 20A1 three front portion 20A3, here, the first front portion 20A1 and 20A2 at the junction of the second boundary portion and the front of the first front portion 20A1 and 20A3 of the third front portion is equidistant the longitudinally away from the lateral reference line Ox-Ox.

在该生理用卫生巾中,上述第一前方部分20A1对着阴道口(N),第三前方部分20A3对着上述阴道口(N)的后方。 In this sanitary napkin, the first front portion 20A1 toward the vaginal opening (N), the third front portion 20A3 toward above the vaginal opening (N) in the rear. 在本说明书中,由于可以将与对着阴道口的部分相比位于更后方的中央区域20的部分定义为中央区域20的后方部分,因此,在图5所示的实施方式中,也可以将20A3的部分包括在后方部分20B中。 In the present specification, since the opposite portion defines a portion of the vaginal opening is located more rearward compared to the central region 20 of the rear portion of the central region 20, therefore, in the embodiment shown in FIG. 5, may be It includes a rear portion 20A3 of the portion 20B. 但是,在图5的实施例中,将20A3的部分与后方部分20B区别,如上所述称为第三前方部分。 However, in the embodiment of FIG. 5, the portion of the rear portion 20A3 20B distinction, as described above as the third front portion.

在图5中,在中央区域20内,用没有涂黑的白圈表示压花部26。 In FIG. 5, in the central region 20, a white circle denotes no black embossed portion 26. 但是省略了液体渗透孔的图示。 But not shown liquid penetration hole.

上述各个压花部26全部用相同的面积形成,但是其密集度,即单位面积的压花部26的数量在与阴道口接触的第一前方部分20A1上低,在后方部分20B、第二前方部分20A2和第三前方部分20A3上高。 Each of the embossing portions 26 are all formed with the same area, but the intensity, i.e., the number per unit area of ​​the embossed portion 26 on the lower front portion of the first contact with the vaginal opening 20A1, 20B in the rear portion, a second front a front portion and a third portion 20A2 high 20A3.

另外,如果将(第一前方部分20A1的压花部26占有的面积总和)/(第一前方部分20A1的面积)作为压花密度A1,将(第二前方部分20A2的压花部26占有的面积总和)/(第二前方部分20A2的面积)作为压花密度A2,将(第三前方部分20A3的压花部26占有的面积总和)/(第三前方部分20A3的面积)作为压花密度A3,将(后方部分20B的压花部26的占有面积总和)/(后方部分20B的面积)作为压花密度B,则压花密度A1比压花密度A2、A3以及压花密度B的任何一个都低。 Further, (the total area of ​​the first embossed portion 26 of the front portion 20A1 occupied) if / (area of ​​the first front portion 20A1) is embossed density as A1, the (second front portion 20A2 of the embossed portion 26 occupies Total area of ​​the total area) / (area of ​​the second front portion 20A2) is embossed density as A2, the (third portion 20A3 of the anterior embossed portion 26 occupied) / (the area of ​​the front portion 20A3 of the third) density as embossed A3, the (sum of the embossed portion 26 of the rear portion 20B of the occupied area) / (area of ​​the rear portion 20B) as the embossing density B, the density of the embossed A1 embossing density than the density of any B A2, A3 and embossed have a low. 并且,在本实施方式中,压花密度A2和压花密度A3及压花密度B大致相等。 Further, in the present embodiment, the density of the embossed and the embossing density A2 and A3 is substantially equal to the embossing density B. 压花密度A1最好是小于或等于压花密度A2、A3以及压花密度B的1/5,小于或等于1/10更好。 A1 is preferably embossed density equal to or less than the density of the embossing A2, A3 and embossing density B 1/5, 1/10 or less better.

因此,用(前方部分20A的压花部26占有的面积总和)/(前方部分20A的面积)表示的压花密度低于用(后方部分20B的压花部26占有的面积总和)/(后方部分20B的面积)表示的压花密度,前者的压花密度为后者的压花密度的1/5以下,1/10以下更好。 Thus, embossing with a density (the sum of the area of ​​the front portion 20A of the embossed portion 26 occupied) / (the area of ​​the front portion 20A) shown below (the total area of ​​the embossed portion 26 of the rear portion 20B occupied) with / (rearward density area of ​​the embossed portion 20B) represented by the density of the embossing former is 1/5 or less of the density of the embossed latter 1/10 or less is better.

另外,在图5所示的实施方式中,在内侧压缩槽11、11的弯曲部11B、11B的后方,在后方倾斜部11D、11D的内侧形成短压缩槽18、18。 Further, in the embodiment shown in FIG. 5, the compression inside the grooves 11 of the rear of the curved portion 11B, 11B, and the rear inclined portion 11D, 11D short inner compressed grooves 18, 18 are formed. 该短压缩槽18、18与上述各压缩槽11至17相同,顶片3和液体吸收层4被压缩,是高密度压缩部和中密度压缩部相互交错而形成。 The compressed grooves 18, 18 and the short to the same respective compressed grooves 1117, the top sheet 3 and the liquid absorbent layer 4 is compressed, and a high density compressed portions are interdigitated density compressed portions are formed as described above.

这样,在后方部分20B上,除了点状的压花部26以外,有上述短压缩槽18、18存在,关于上述点状的压花部26的压花密度的定义,上述短压缩部的面积不含在压花部26占有面积的总和内。 Thus, in the rear portion 20B, except for the point-like embossed portion 26, there is the presence of the short compressed grooves 18, 18, the embossed area is defined on the density of the dot-shaped embossed portion 26 of the short portion of the compression excluding the sum of the area occupied by the embossed portion 26.

作为具有图5所示压花部26的布局图案的生理用卫生巾,可以构成以下所示的第二实施方式和第三实施方式。 Physiological having a layout pattern shown in FIG. 5 of the embossed portion 26 of the sanitary napkin, may be configured as shown in the following second embodiment and third embodiment.

在第二实施方式中,覆盖上述中央区域20的顶片3用与图1所示的第一实施方式相同的无纺布形成,与图3所示的相同,形成贯通顶片3和第二片5的液体渗透孔25。 In the second embodiment, the top sheet covering the central region 20 is the same as with the first embodiment 3 shown in FIG embodiment of nonwoven fabric, the same as that shown in FIG. 3, is formed through the top sheet 3 and the second a liquid permeable pores 25 of the sheet 5. 该液体渗透孔25可以与图1相同地分布在前方部分20A的整个区域,也可以均匀地分布在第一前方部分20A1和第二前方部分20A2上。 The liquid permeable pores 25 may be distributed in the same manner of FIG. 1 in the entire area of ​​the front portion 20A, it can be uniformly distributed on the second front portions 20A1 and 20A2 of the first forward portion. 而且,在第二实施方式中,上述液体渗透孔25也可以形成在后方部分20B上。 Further, in the second embodiment, the liquid permeation holes 25 may be formed on the rear portion 20B.

但是,用(前方部分20A的液体渗透孔25的开孔面积的总和)/(前方部分20A的面积)表示的开孔密度高于(后方部分20B的液体渗透孔25的开孔面积的总和)/(后方部分20B的面积)的开孔密度。 However, with the density of openings (open area is the sum of the forward portion 20A of the liquid permeable pores 25) / (the area of ​​the front portion 20A) is higher than (the sum of the open area of ​​the liquid permeable pores 25 of the rear portion 20B) / (the area of ​​the rear portion 20B) opening density. 另外,用(后方部分20B的上述压花部26占有面积的总和)/(后方部分20B的面积)表示的压花密度高于(前方部分20A的上述压花部26占有面积的总和)/(前方部分20A的面积)的压花密度。 Further, using embossing density (the sum of the embossing portion 20B of the rear portion 26 of the occupied area) / (area of ​​the rear portion 20B) is higher than (the sum of the area occupied by the front portion 20A of the embossing unit 26) / ( the area of ​​the front portion 20A) of the embossing density.

这样,在图5中,将20A1的范围和20A2的范围定义为前方部分,将20A3的范围和20B的范围定义为后方部分时也同样。 Thus, in FIG. 5, the range of the scope 20A1 and 20A2 of the front portion is defined as the range defined as a range of 20A3 20B and also when the rear portion.

这样,在前方部分20A上,由于许多液体渗透孔25存在,因此,在前方部分20A的特别是第一前方部分20A1上,经血可以通过自重经过液体渗透孔25迅速地向液体吸收层4转移。 Thus, in the front portion 20A, since the plurality of liquid permeable pores 25 exist, therefore, in particular, the front portion 20A of the first forward portion 20A1, menstrual blood can by its own weight through the liquid permeable pores 25 rapidly transferred to the liquid absorbing layer 4. 另外,在前方部分20A的特别是第一前方部分20A1上,由于压花部26少,因此降低压花部26与阴道口接触的概率。 Further, the front portion 20A of the first particular front portion 20A1, due to the small embossed portion 26, thus reducing the probability of the embossed portion 26 in contact with the vaginal opening.

另一方面,在后方部分20B上,由于许多压花部26存在,因此,在后方部分20B进入臀沟内、受到来自使用者身体的压力或摩擦力时,可以防止在位于后方部分20B上的顶片3上起毛或从液体渗透孔25产生破裂。 On the other hand, in the rear portion 20B, since there are many embossed portions 26, therefore, the rear portion 20B into the gluteal groove, under pressure or friction from the user's body can be prevented in the portion 20B located behind raising the generation of cracks or the top sheet 3 from liquid penetration hole 25.

另外,如图5所示,在位于压花部26的数量少、主要存在液体渗透孔25的第一前方部分20A1的前后位置上的第二前方部分20A2和第三前方部分20A3上,由于压花部26的密集度高,因此,顶片被第一前方部分20A1的前后加固,可以防止在第一前方部分20A1,在顶片上产生过大的褶皱或由液体渗透孔25引起的破裂。 Further, as shown, located in a small number of embossed portions 26, primarily on the second and third front portion of the front portion 20A2 20A3 20A1 on the front and rear positions of the front portion 25 of the first liquid permeation holes, since the pressing 5 high density portion 26 of the flowers, and therefore, the front and rear portions of the top sheet of the first front reinforcement 20A1 can be prevented in the first front portion 20A1, excessive wrinkles or breakage caused by the liquid permeable pores 25 in the topsheet.

在本发明的第三实施方式中,覆盖图5所示的中央区域20的顶片由具有液体渗透孔的树脂薄膜形成。 In a third embodiment of the present invention, the cover 5 shown in FIG. 20 central region of the topsheet is formed of a resin film having liquid permeable pores.

上述树脂薄膜是例如由于含有氧化钛而混浊的聚乙烯薄膜,厚度为15~50μm左右。 For example, the resin film is clouded due to the titanium oxide containing polyethylene film having a thickness of approximately 15 ~ 50μm. 将软化状态的树脂薄膜向具有许多开孔的滚筒表面供给,通过从滚筒的内侧吸引空气,可以形成许多液体渗透孔。 The softened state of the resin film is supplied to the drum surface having a plurality of openings, air being sucked from the inside of the drum, a number of liquid permeation holes can be formed. 上述各个液体渗透孔是圆形、长圆形。 Each of the above liquid penetration aperture is circular, oblong. 或者树脂薄膜也可以是网结构,网孔部分发挥液体渗透孔的作用。 Or a resin film may be a mesh structure, the mesh part of the role of the liquid permeable pores. 各个液体渗透孔的平均开孔尺寸为0.2~2mm,液体渗透孔的开孔密度最好为10~30%。 The average opening size of each of the liquid permeation holes 0.2 2mm ~, hole density of the liquid permeable pores is preferably 10 to 30%.

在图5中,具有许多液体渗透孔的上述树脂薄膜作为表面层3使用、覆盖中央区域20(以及其他区域)的情况下,在整个中央区域20上,液体渗透孔被均匀地分散设置。 In the case of FIG. 5, the resin film having a plurality of liquid permeation holes 3 is used as a surface layer, covering 20 (and other regions) of the central region, over the entire central region 20, the liquid permeation holes are disposed uniformly dispersed.

在这种情况下,在图5所示的压花部26上,上述树脂薄膜和位于其下面的第二层被一起加热、加压,在压花部26上树脂薄膜的顶片3和第二层5被一体化。 In this case, the embossed portion 26 shown in FIG. 5, the resin film and beneath it a second layer is heated together with pressurizing, the resin film topsheet 26 of the embossed portion 3 and Layer 5 is integrated. 另外,在压花部26上,第二层5的纤维密度增大。 Further, the embossed portion 26, the fiber density of the second layer 5 is increased.

在该第三实施方式中,在前方部分20A上,经血也可以渗透形成在树脂薄膜上的液体渗透孔、依靠自重经过第二层5的纤维间、迅速向液体吸收层4转移。 In this third embodiment, in the front portion 20A, menstrual blood may permeate liquid penetration holes formed in the resin film, through its own weight between the fibers of the second layer 5, the transfer layer 4 to quickly absorb the liquid. 另外,在前方部分20A特别是第一前方部分20A1上,由于压花部26少,因此降低压花部26与阴道口接触的概率。 Further, in the front portion 20A of the first forward portion 20A1 in particular, due to the small embossed portion 26, thus reducing the probability of the embossed portion 26 in contact with the vaginal opening.

在后方部分20B上,经血也可以经过形成在顶片3上的液体渗透孔、迅速向液体吸收层4转移,与此同时,在许多压花部26上,经血被强力吸引到第二层5的纤维密度高的部分上。 In the rear portion 20B, the blood may be formed through liquid permeation holes 3 on the topsheet rapidly transfer to the liquid absorbing layer 4, while in many embossed portions 26, menstrual blood is strongly attracted to the second layer 5 high fiber density portion. 另外,在后方部分20B通过许多压花部26、顶片3和第二层5接合,因此可以防止进入臀沟内的后方部分20B受到来自使用者身体的压力或摩擦力时,在用树脂薄膜形成的顶片3上产生过大的褶皱。 Further, in the rear portion 20B by a number of embossed portions 26, the top sheet 3 and the second layer 5 is engaged, it is possible to prevent the rear portion 20B of the under pressure into the gluteal or friction from the wearer's body, the resin film 3 is formed on the top sheet excessive wrinkles.

另外,树脂薄膜的顶片3和第二层5被热熔粘接剂粘接,密合度被提高,但在压花部26上,由于顶片3和第二层5被接合,因此可以使上述热熔粘接剂的涂抹量少,因此,液体从顶片3到第二层5的渗透被热熔粘接剂妨碍的可能性小。 Further, the topsheet 3 and the second resin film layer 5 is hot melt adhesive bonding, adaptation is increased, but the embossed portion 26, since the top sheet 3 and the second layer 5 is engaged, it is possible to make apply a small amount of the above-described hot-melt adhesive, therefore, is less likely to permeate the top sheet 3 to the second layer 5 of the liquid hot melt adhesive is disturbed.

虽然就实施例对本发明进行了图示和说明,但上述以及其他的各种变更、省略、追加不超出本发明的精神以及范围而构成本发明是本领域技术人员当然可以理解的。 Although the embodiments of the present invention it has been shown and described, the foregoing and other various changes, omissions and additions without departing from the spirit and scope of the present invention and the present invention is configured skilled in the art can certainly understand. 例如,也可以不设置前方连接压缩槽12、后方连接压缩槽14,而使左右的内侧压缩槽11和11相互独立。 For example, the connection may not be provided in front of the compressed groove 12, the rear connecting compressed groove 14, the inner side of the right and left compressed grooves 11 and 11 independently of each other. 因此,应该理解为本发明不局限于在此所述的特定的实施例,而包含关于所附的权利要求中所述的特征,其涉及的范围内以及在均等范围内被进行具体化的所有可能的实施方式。 Accordingly, it should be understood that the present invention is not limited to the specific embodiments described herein but includes features in respect of the appended claims, and all of the specific range within the range of equalization according to which possible embodiments.

如上所述,在本发明中,通过被压缩槽夹住的纵长的中央区域可以确实收集经血,可以有效地防止经血向后方转移。 As described above, in the present invention, by being sandwiched between the compressed grooves longitudinal central region can surely collect menstrual blood, menstrual blood can be effectively prevented from transferring backward. 另外,可以提高中央区域的顶片的耐久性,可以消除由于受到来自使用者身体的力而产生过大的褶皱、或产生破裂的不安。 Further, it is possible to improve the durability of the central region of the top sheet can be eliminated due to the force from the user's body and excessive wrinkles, generation of cracks or anxiety.
