在附图所示实施例中的吸湿芯42优选包括可全向弹性伸长的针织材料。 In the illustrated embodiment of the absorbent core 42 preferably comprises a knitted material may be stretched to the full elastic accompanying drawings. 本文中所用术语“全向”伸长是指在xy平面内所有方向上的可伸长性。 As used herein, the term "omnidirectional" means elongation extensibility in all directions in the xy plane. 在一个特别优选的实施例中,吸湿芯42是两层或多层针织材料的层叠部件。 In a particularly preferred embodiment, the absorbent core 42 is a laminate of two or more components of a multi-layer knitted material. 优选的是,吸湿芯42包括三层结构,这三层结构包括针织尼龙材料层、针织聚酯材料层和针织20/1丙烯酸材料层,这些材料层通过提供带有提花绗缝图案的层压物的接结(stitching)缝合在一起。 Preferably, the absorbent core 42 comprises a three-layer structure, three-layer structure which comprises a layer of knitted nylon material, knit polyester material, and knit 20/1 layer acrylic material layer, these materials provide a laminated layer with a jacquard quilted pattern of the binding material (stitching) sewn together. 这种材料是产品号为B7112的公知产品而且可从Burlington,NC的Flynt Amtex公司得到。 This material is the product number B7112 known products and can, NC available from the company Flynt Amtex Burlington. Flynt材料的定量为24mg/cm2,吸收容量大于或等于约5克水/克织物和厚度约为2mm。 Quantitative Flynt material is 24mg / cm2, the absorption capacity of greater than or equal to about 5 grams of water / gram of fabric and a thickness of about 2mm. 在以下的试验方法部分中将描述为确定这种材料的容量而进行的简单试验。 It described simple experiments to determine the capacity of this material is carried out in the Test Methods section below.

在下列给定力作用下吸湿芯42(例如Flynt材料)优选能够以下列量全向伸长:在小于或等于约20克/英寸(约8g/cm)的力作用下伸长5%;在小于或等于约35克/英寸(约14g/cm)的力作用下伸长10%;在小于或等于约200克/英寸(约80g/cm),优选小于或等于约100克/英寸(约40g/cm),更优选小于或等于约85克/英寸(约33g/cm)的力作用下伸长25%;在小于或等于约225克/英寸(约90g/cm)的力作用下伸长50%。 In the following given force (e.g. Flynt material) is preferably the absorbent core 42 can be stretched to the full in the following amounts: 5% elongation at about 20 grams / inch (about 8g / cm) is less than or equal to the force; in 10% elongation of less than or equal to about 35 grams / inch (about 14g / cm) under the action of a force; less than or equal to about 200 grams / inch (about 80g / cm), preferably less than or equal to about 100 grams / inch (about 40g / cm), more preferably less than or equal to 25% elongation at about 85 g / inch (about 33g / cm) of force; stretch under the forces of less than or equal to about 225 grams / inch (about 90g / cm) of 50% long. 如在以下的试验方法部分中将要描述的那样,在此给定的所有力都是用一英寸(2.54cm)宽的吸收材料条测得的。 As described in the Test Methods section below to be described in this all the force is given a broad absorption material strip measured with one inch (2.54cm). 为简单起见,使用沿纵向、横向和45°对角方向上切下的长条来测量全向伸长性。 For simplicity, the use of the longitudinal, lateral, and 45 ° measured in a diagonal direction of the strip cut omnidirectional extensibility.

优选吸湿芯42(例如Flynt材料)可在各方向上弹性伸长。 Preferably the absorbent core 42 (e.g. Flynt material) elastically extensible in all directions. 消除拉伸力之后,吸湿芯42可以但不必完全返回到其未伸长时的尺寸。 After elimination of the tensile force, the absorbent core 42 can but does not need to return to their unstretched dimensions. 这一特征可以用芯材料的永久变形百分比(%)来描述。 This feature can be permanent deformation of the core material percentage (%) will be described. Flynt材料在纵向、横向和对角方向上的永久变形小于或等于10%。 Flynt material in the longitudinal, lateral and permanent deformation in the diagonal direction is less than or equal to 10%.

优选的吸湿芯42(例如Flynt材料)是极柔顺和悬垂的。 Preferred absorbent core 42 (e.g. Flynt material) is extremely supple and drapable. 用授予Osborn的美国专利5009653中描述的试验对Flynt材料进行单独测定,Flynt材料的泰伯挺度为约0.11或0.12g cm;抗弯刚度为约26mg cm/cm;抗弯性约为14或15克。 Test performed with U.S. Patent No. 5,009,653 issued to Osborn described measurement of the Flynt material alone, Taber stiffness Flynt material is about 0.11 or 0.12g cm; flexural stiffness of about 26mg cm / cm; or bending resistance of about 14 15 grams.

优选将第三可伸长区48设置在第一可伸长区44另一侧的至少一部分第一可伸长区44的横向外侧。 Preferably at least a third portion of the first region of extensibility 48 may be extensible zones 44 provided on the other side of the first outside lateral zones of extensibility 44. 优选使第三可伸长区48朝着卫生巾20主体部分22的一个纵向侧缘26上延伸。 Preferably the third region of extensibility 48 of the sanitary napkin the main body 20 toward a longitudinal portion 22 extending side edges 26. 第三可伸长区48还可伸到侧翼24中。 The third region of extensibility 48 may further out into the flank 24. 覆盖主体部分22的第三可伸长区48部分也大致上呈直角三角形。 The third portion 48 covers the main body portion of the zones of extensibility 22 are also substantially right-angled triangle. 在附图所示的实施例中,第三可伸长区48可以在纵向和横向之间的方向上伸展。 In the embodiment illustrated in the drawings, the third region of extensibility 48 may extend in a direction between the longitudinal and transverse direction. 优选的是,在该实施例中,第三可伸长区48还具有沿基本矢量分量方向向内定向的可伸长性,所述基本矢量分量与纵向中线L形成的角度在约45°和约55°之间,优选为约48°。 Preferably, in this embodiment, the third region of extensibility 48 also has a vector component of extensibility in a direction substantially inwardly directed, and the angle of the vector component substantially formed longitudinal centerline L at about 45 ° and about between 55 °, preferably about 48 °. 在附图所示的优选实施例中,第二和第三可伸长区46和48对称地设置在第一可伸长区44的两侧上。 In the embodiment shown in the accompanying drawings a preferred embodiment, the second and third regions of extensibility 46 and 48 are symmetrically disposed on both sides of the first region 44 may be elongated.

卫生巾20与许多已有的吸湿用品的不同之处在于其优选具有沿对角方向分布的整体伸长性。 The sanitary napkin 20 with many prior absorbent articles in that it preferably has a different overall extensibility in a diagonal direction of the distribution. 本文中使用的“对角”是指通常从主体部分的一个角27到纵向和横向中线的对侧的角27。 As used herein, "diagonal" means generally from one corner angle 27 of the body portion 27 and transverse to the longitudinal centerline of the opposite side. 该对角示于图5中。 The diagonal shown in Figure 5. 如图5所示,优选将卫生巾20主体部分22上所有伸长性的主方向确定在与纵向中线L成角度B的方向上。 5, preferably all the main direction of the elongated body portion 22 of the sanitary napkin 20 determines the direction of the longitudinal centerline L of the angle B. 角度B大于0°并小于45°,而且优选在约15°和约30°之间,而对图中所示实施例而言,优选为约20°。 Angle B is greater than 0 ° and smaller than 45 °, and preferably between about 15 ° and about 30 °, while the embodiment shown in the Figures, it is preferably about 20 °.

应理解的是,优选使卫生巾20可在主体部分22的四个角之间的两个对角方向上伸长。 It should be understood that the two may be preferred that the sanitary napkin 20 between the four corners of the main body portion 22 of the elongated diagonal direction. 因此,卫生巾20不仅具有按图5所示角度B定向的主伸长分量(其中该角度相对于纵向中线L逆时针转动),而且还具有以相同角度相对于纵向中线L顺时针转动的分量。 Thus, not only the sanitary napkin 20 has a main elongated component oriented at an angle as shown in FIG. 5 B (wherein the angle with respect to the counterclockwise rotation of the longitudinal centerline L), but also has a component at the same angle relative to the longitudinal centerline L in the clockwise rotation of the .

优选使图中所示卫生巾20能够在下列给定力的作用下产生下列量的对角伸长:在小于或等于约200克力的作用下伸长5%;在小于或等于约500克力的作用下伸长10%;在小于或等于约850克力的作用下伸长15%;在小于或等于约1500克力的作用下伸长25%。 Preferably the sanitary napkin shown in FIG. 20 can generate the following amounts of the following diagonal elongation given force action: action at 5% elongation of less than or equal to about 200 grams; and less than or equal to about 500 grams the force of elongation of 10%; 15% elongation under the effect of less than or equal to about 850 grams; and 25% elongation under the effect of less than or equal to about 1500 grams force. 在此所用所有给定的力均是用下述测量方法部分中所述的一英寸(2.45cm)宽的夹持器测得的。 As used herein, all forces are given by the following measuring method described in the section one inch (2.45 cm) wide as measured in the holder. 优选使卫生巾20在对角方向上弹性伸长。 Preferably the sanitary napkin 20 in a diagonal direction of the elastic elongation. 在卫生巾已进行对角伸长后,卫生巾20可以有少量永久变形(约达10%)。 In the rear corners of the sanitary napkin has been stretched, the sanitary napkin 20 may have a small amount of set (up to about 10%).

在前面的段落中讨论的所有伸长方向的情况下,优选使卫生巾20在较低作用力的水平下没有太大的可伸长性以至于难以将卫生巾固定到穿用者的内衣上。 When all elongation directions discussed in the preceding paragraphs, the sanitary napkin 20 preferably at a level not lower too much force on the undergarment that it is difficult extensibility the sanitary napkin secured to the wearer . 优选在具有上述给定伸长性的每个方向上在小于或等于约50克的力作用下使卫生巾20的伸长量不太于或等于约10%。 The sanitary napkin is preferably less than or equal to about 50 grams force in each direction at a given elongation with the above elongation of 20 is less than or equal to about 10%. 然而,应该认识到,与在本文中给出的伸长量是优选量一样,本发明的吸湿用品并不限于具有上述伸长量的用品,除非在所附的权利要求中另有规定。 However, it should be appreciated that the amount of elongation is given herein as preferred amount, the absorbent article of the present invention is not limited to the above-described elongation of articles having, unless otherwise specified in the appended claims.

由于本文所述顶片38和底片40各区的伸长方向以及优选吸湿芯42的全向伸长性,所以能够实现对角拉伸。 Since the direction of elongation of the topsheet 38 and backsheet 40 and preferably the absorbent core zones omnidirectional extensibility, it is possible to achieve 42 herein diagonal stretching. 对角整体伸长性使卫生巾20具有几个优点。 Overall diagonal extensibility of the sanitary napkin 20 has several advantages. 对角伸长性有助于卫生巾适应走路或类似运动时穿用者紧身短衬裤的对角拉伸。 The diagonal extensibility helps the sanitary napkin adapt to the wearer's panty diagonal stretching motion while walking or the like. 对角整体伸长性减小了卫生巾上的张力,该张力会引起卫生巾的端缘部分折叠到主体部分22的其余部分上等不希望出现的趋势(即,可防止端缘“翻转”(roll over),出现导致不能盖住穿用者内衣和弄脏穿用者内衣的问题)。 Overall extensibility angle decreases tension on the sanitary napkin, the tension causes edge portions of the sanitary napkin folded onto the remainder of the body portion 22 of the upper undesirable trend (i.e., the edge is prevented to "flip" (roll over), leading to not cover the wearer's undergarment and stain the wearer's undergarments problems). 在不希望受任何特定理论限制的情况下,可以相信减少端部翻转至少部分归因于卫生巾20能够更好地适应上述对角拉伸的事实。 Without wishing to be bound by any particular theory, it is believed to reduce the end flipping the sanitary napkin 20 at least partly due to better adapt to the fact that the aforementioned diagonal stretching. 此外,将卫生巾设计成在对角方向上比在纵向上有更大伸长性将使得卫生巾沿纵向中线(比最大伸长性出现在纵向上的卫生巾)具有更大挺度,其也能减少端缘翻转。 Further, the sanitary napkin is designed to have a diagonal direction than in the longitudinal direction so that the greater extensibility of the sanitary napkin have a greater stiffness in the longitudinal centerline (than a maximum extensibility in the longitudinal direction of the sanitary napkin occurs), which can be reduced edge rollover.

可以用任何合适的方法使卫生巾20和卫生巾的不同区域具有可伸长性。 Any suitable method may be used so that different regions of the sanitary napkin and the sanitary napkin 20 having extensibility. 在图中所示的实施例中,通过在卫生巾20的顶片38和底片40的所需区域中形成变形网便能够使其具有可伸长性。 Embodiment illustrated in the figures, by forming a strainable network in the desired region of the sanitary napkin 20 the topsheet 38 and backsheet 40 will be able to have extensibility. 通过本文中所述将顶片和底片基材制成可拉伸的类似弹性的薄膜(或将顶片和底片基材“SELF”化)的方法来制做变形网。 Elastic film by a method analogous to the described herein the topsheet and backsheet may be made of stretchable substrate (or the top sheet and backsheet base "SELF" of) making modification to the network. 在顶片38和底片40中形成变形网的合适方法公开在1996年5月21日授予Chappell等人的题为“显现类似弹性特征的网状材料”的美国专利5518801中。 "Elastic-like web material show features" strainable network suitable method of forming the topsheet 38 and the backsheet 40 is disclosed in May 21, 1996 issued to Chappell, et al., U.S. Patent No. 5,518,801, entitled In.

当可变形网处于未拉伸的状态下时,根据在这些区域表面上测得的各区域的地形长度(或第一和第二网状区的“表面路径长度”)来描述第一和第二网状区64和66的特征。 When the state strainable network is in an untensioned, depending on the terrain the length of each region on the surface of the measured region ( "surface-pathlength" or the first and second mesh regions) will be described first and second wherein two mesh regions 64 and 66. 第二网状区66的表面路径长度大于第一网状区64的表面路径长度。 Surface-pathlength of the second region 66 is greater than the mesh surface-pathlength of the first region 64 of the web. 当在可变形网上施加伸长力时,凸形件74产生几何变形,在该变形状态下,凸形件74将变得扁平和伸展,同时第一区将产生分子级的变形。 When the stretching force is applied to the deformable web, the male member 74 geometric distortion generated in the deformed state, the male member 74 will flatten and extend while the first regions will have a molecular level deformation. 当受到施加并随后释放的伸长力时将使变形网状区在箭头的方向上显现出类似弹性的特性。 When subjected to a force is applied and subsequently released elongation deformation reticular region will exhibit elastic-like properties in the direction of the arrow. 在授予Chappell等人的美国专利5518801中更详细地描述了可变形网状区的一般特性。 Issued to Chappell et al. In U.S. Patent No. 5,518,801 describes the general characteristics of the deformable mesh region in more detail.

通过在啮合构图辊之间分别输送顶片和底片基材,在具有图形的配合板之间压榨基材或是通过铸造可以制成可变形网。 Through the backsheet and topsheet are transported between the substrate engaging patterned rolls, between the press fit base plate having a pattern or may be made by casting strainable network. 在附图中所示的卫生巾20的各部件的组装中可在几个阶段形成可变形网。 Assembling the components of the sanitary napkin 20 shown in the drawings may be formed in several stages strainable network. 在将可变形网连接在一起制成卫生巾之前,可以将可变形网制成卫生巾的部件。 Before the sanitary napkin is made together strainable network, the strainable network can be made part of the sanitary napkin. 此外,可以将可变形网制成整体组装的卫生巾。 In addition, the strainable network formed integrally assembled sanitary napkin. 优选的是,在图中所示的实施例中,在将可变形网连接到一起之前将可变形网制入顶片38和底片40中并在顶片和底片之间包入吸湿芯42。 Preferably, the embodiment shown in the drawings, the strainable network is connected to the previously prepared with the strainable network into the topsheet 38 and the backsheet 40 and between the backsheet and the topsheet 42 wrapped in the absorbent core. 如上所述,由于吸湿芯42优选具有全向伸长性,所以吸湿芯42可以但不是必须具有在其中形成的可变形网。 As described above, since the absorbent core 42 preferably has omnidirectional stretchability, so that the absorbent core 42 may, but not necessarily having a strainable network formed therein. 在图中所示的实施例中,优选使吸湿芯42不具有在其中形成的可变形网。 Embodiment illustrated in the figures, preferably, the absorbent core 42 does not have a strainable network formed therein.

顶片38和底片40上伸到吸湿芯42边缘之外的部分形成凸缘76。 Other than the edge portion 42 out into the absorbent core 40. The topsheet 38 and backsheet 76 to form a flange. 可以用任何不会影响卫生巾拉伸能力的方式将顶片38和底片40的这些部分连接起来。 May be stretched in any manner does not affect the ability of the napkin to these portions of the topsheet 38 and backsheet 40 are connected together. 在图中所示的实施例中,优选使用在延伸到吸湿芯42边缘外侧的基本上整个部分上的可伸长粘合剂和为主体部分22的端缘28处增加强度而设置的波纹性封口78将顶片38和底片40连接起来,在所述封口处通过施加压力或加热和加压将顶片38和底片40压实。 Embodiment illustrated in the figures, it is preferred to use extending over substantially the entire portion of the outer edge 42 of the absorbent core and extensible adhesive to the edge of the corrugated portion 22 increases the strength of the main body 28 is provided sealing the topsheet 78 and backsheet 40 are connected 38, the seal through the application of pressure or heat and pressure the topsheet 38 and backsheet 40 compaction. 合适的可伸长粘合剂是可从MN,Badnais Heights的HBFuller公司买到的Fuller 2352粘合剂。 Suitable extensible adhesive available from MN, Badnais Heights HBFuller of Fuller 2352 adhesive available company. 优选用少量粘合剂接触吸湿芯42的边缘以便将吸湿芯42固定。 The absorbent core 42 preferably is fixed to a small amount of adhesive contacts the edges of the absorbent core 42.

波纹性封口78不应影响卫生巾各部件的拉伸能力。 Sealing bellows 78 of the components should not affect the ability to stretch the sanitary napkin. 优选使由波纹性封口78连接的卫生巾的可伸长部分能够伸长上述给定的量和使卫生巾20处于上述给定力的作用下(例如参见端区中的横向伸长性)。 Preferably 78 to seal it by the corrugations of the sanitary napkin may be connected to an elongated portion can elongate the amount given above and the sanitary napkin 20 in the above-described action of a given force (e.g., see the transverse extensibility in the end regions). (然而,波纹性封口78能够使部件在多个方向上伸长。)因此,可以将波纹性封口78称为可伸长的波纹性封口(尽管在不使用可伸长部件的情况下波纹性封口78不会提供任何固有的伸长性)。 (However, the seal 78 can be made of corrugated elongate member in multiple directions.) Accordingly, the waviness of the sealing bellows seal 78 may be referred to as the elongation (although waviness without the use of an elongated member sealing 78 does not provide any inherent extensibility). 波纹性封口78优选含有不透液密封。 Waviness seal 78 preferably contains a liquid tight seal. 波纹性封口78优选形成正弦密封线,沿该线至少将顶片38和底片40之一的一部分压在一起和/或熔合在一起。 Sealing bellows 78 is preferably formed of a sinusoidal sealing line along which the line pressure of at least a portion of one of the topsheet 38 and backsheet 40 together and / or fused together. 图1中所示的波纹性封口78是优选布置成大致曲线构型的正弦图形。 Waviness shown in FIG. 1 seal 78 is preferably arranged substantially sinusoidal pattern of curved configuration. 还可以使用其它构型,例如直的正弦图形。 Other configurations may also be used, such as straight sinusoidal pattern. 如果不希望受任何特定理论的限制,则可以认为波纹性封口78允许卫生巾上靠近封口的部分伸长,这是困为正弦构型的波形使波纹形封口78具有“松紧”性,由此可以将波纹形封口78拉伸到使其至少部分变直。 Without wishing to be bound by any particular theory, it may be considered of a sealing bellows 78 allows the sanitary napkin near the elongate sealing portion, which is trapped sinusoidal wave configuration so that the seal 78 has a corrugated "elastic" properties, whereby corrugated seal 78 can be stretched so as to at least partially straighten.

可以采用各种可伸长的波纹形封口78。 It may be various corrugated elongate seal 78. 例如,可以将波纹形封口布置在包括侧翼远端缘的卫生巾整个周边上或周边的任一部分上(下面将描述)。 For example, the corrugated portion of the seal disposed on either side flaps comprising a distal edge on the periphery or the entire sanitary napkin periphery (described below). 除了正弦图形外,还可以使用其它能提供所需“松紧”性的图形,这些图形包括但不限于锯齿形图形。 In addition to the sinusoidal pattern, other may also be used to provide the desired "tightness" of the pattern, these patterns include but are not limited zigzag pattern. 可伸长的波纹形封口78的正弦(或其它)图形的带宽、幅值和频率可以改变。 Extensible sinusoidal corrugated seal 78 (or other) pattern bandwidth, amplitude and frequency can be varied. 此外,多个正弦波(或具有其它构型的波)在彼此相邻的相位上相接。 Further, a plurality of sine waves (or waves having other configurations) in contact with the adjacent phases. 可以用这种多个波纹形封口来确保在加工后在卫生巾周边的所需部分上存在连续的波纹。 This plurality may be used to ensure a continuous corrugated bellows seal exists on a desired portion of the periphery of the sanitary napkin after processing. 例如,在生产过程中可以切断波纹形封口。 For example, in the production process can be cut corrugated sealing. 当通过最后的切割操作(或通过“最终的刀”)在端缘处将卫生巾网状物切割成单个卫生巾时这是最经常发生的。 When the cutting operation by the last (or the "final knife") the web into individual sanitary napkin at the end edge of the sanitary napkin which is the most frequently occurring. 多个波纹形封口将能确保即使在生产过程中将一部分波纹形封口切下,液体也不会芯吸通过波纹封口78。 A plurality of corrugated seal will ensure that even in the production process will cut a portion of a corrugated seal, the liquid will not wick 78 via a bellows seal.

在其它实施例中,可以将连续的正弦波封口与不连续的(或间断的)接合图形相结合。 In other embodiments, sealing may be a continuous sine wave with discontinuous (or intermittent) pattern bonded combination. 不连续的接合图形可以是不连续的正弦波或其它合适的不连续图形形式。 Discontinuous pattern bonding may not be a continuous sine wave or a discontinuous pattern other suitable form. 不连续图形的结构应该使得在生产过程中如果切下波纹形封口上的任何一部分,不连续图形都将形成曲折的流路来挡住试图通过波纹形封口芯吸的任何液体。 Discontinuous pattern structure should be such that if any portion of the cut corrugated seal, are discontinuous pattern meandering flow path formed in the production process to block any attempt by the corrugated sealing liquid wicking. 由于最终在波纹上进行切割的位置并不是很严格,所以这些图形还提高了生产的灵活性。 As the final cut position on the bellows is not very strict, so these graphics also enhance production flexibility.

可伸长的波纹形封口78具有许多优点。 Extensible corrugated seal 78 has a number of advantages. 这些优点包括但不限于以下各项。 These advantages include but are not limited to, the following. 当然,可伸长的波纹形封口78对从卫生巾20端部28芯吸的液体形成不透液屏障。 Of course, stretchable sealing liquid 78 pairs of corrugated absorbent core of the sanitary napkin 28 from the end portion 20 forms a fluid tight barrier. 即使波纹形封口是连续的,该封口也允许卫生巾的各部件伸展。 Even continuous corrugated seal, the seal also allows the components of the sanitary napkin to stretch. 以前认为必须用不连续的接合图形来避免对可伸长吸湿用品各部件的伸长能力造成影响。 Previously thought to be engaged with a discontinuous pattern to avoid impact on the extensible absorbent articles stretchability of each member. 可伸长波纹形封口78还有助于防止不希望出现的卫生巾端缘部分折叠到其余主体部分上的趋势。 Extensible corrugated seal 78 also helps to prevent undesirable side edge portion of the sanitary napkin folded tendency on the remaining body portion. 在不希望受任何特定理论限制的情况下,可以认为出现上述现象是因为可伸长波纹形封口78消除了凸缘76和其余的主体部分22之间伸长性的所有差异,伸长性的差异会在主体部分22受拉伸时使边缘76产生卷曲。 Without wishing to be bound by any particular theory, it is believed the above phenomenon is because the corrugated elongate seal 78 eliminates any differences in extensibility of the flange 76 and the rest of the body portion 22, extensibility differences in the main body portion of the edge will be 22:00 76 under tension curling.

附图1-4中示出的卫生巾20还包括一对连接到主体部分22上的侧翼24。 Figures 1-4 show a sanitary napkin 20 further includes side flaps 22, 24 on the pair of connecting to the body portion. 侧翼24从其近边缘24A到其远边缘(或“自由端”)24B横向向外延伸到主体部分22纵向侧缘26的外侧。 24A from the proximal edge of the flaps 24 to their distal edges (or "free ends") 24B extending laterally outwardly to the body portion 22 of the longitudinal side edges 26 outward. 侧翼24至少从主体部分22的中央区36向外伸展。 Flanking region 24 extends at least from the central portion 22 of the body 36 outwardly. 如图1中所示,每个侧翼24被侧翼横向中线T1分成前半部54和后半部56。 As shown in FIG. 1, each side flap transverse centerline T1 flank 24 is divided into a front half 54 and rear half 56. 侧翼横向中线T1与卫生巾的主横向中线T重合,但这并不是绝对的要求。 Flanking transverse centerline T1 and the transverse centerline T of the sanitary napkin main coincidence, but this is not an absolute requirement. 沿着接缝将每个侧翼24连接到主体部分22上(或附着在其上)。 Seam along each side flap 24 is connected to the body portion 22 (or attached to it). 这通常是纵向定向(或“纵向”)的接缝,例如接缝线68。 This is generally longitudinally oriented (or "longitudinal") of the seam, the seam line 68 for example. 在此所用的术语“接缝”(或“接缝线”)是指侧翼24从主体部分22上开始延伸的区域或连接到主体部分22上的区域。 As used herein, the term "joint" (or "seam lines") refers to a region flanking 24 extends from the body portion 22 or the region 22 is connected to the body portion.

可以用任何合适的方式将侧翼24连接到主体部分22上。 It may be used in any suitable manner to the main body portion 22 connected to the flaps 24. 在此使用的术语“连接”包含了通过将一个部件直接附着到另一部件上而将一个部件直接固定到另一个部件上的结构;通过将一个部件附着到中间部件上再将中间部件附着到其它部件上而将一个部件间接固定到其它部件上的结构;和一个部件与另一个部件成一体,即一个部件基本上是另一部件的部分的结构。 The term "coupled" includes but is directly secured to the one component by a member attached directly to the other element on the other structural member; by a member attached to the intermediate member and then attached to the intermediate member the other member is indirectly secured to a structure member of the other components; and a member integral with another member, i.e. a member substantially another component moiety. 在图1-4所示的实施例中,优选使侧翼24与主体部分22成一体(即,侧翼24是顶片38和底片40的整体延伸部件)。 In the embodiment illustrated in Figures 1-4, it is preferable that the flaps 24 and the main body portion 22 is integral (i.e., flaps 24 are integral extensions of the topsheet 38 and backsheet 40 members).

可以用任何合适的方式将含有侧翼24的顶片38及底片40的伸长部分连接到一起。 Elongate portion of the topsheet may be contained in any suitable manner to the backsheet 38 and flaps 24, 40 are connected together. 例如,可以在其整个界面上或其任何合适的部分上通过粘合剂将形成侧翼的顶片38及底片40的伸长部分连到一起来形成侧翼24。 For example, the topsheet may be formed, or over the entire flank interface on any suitable portion of the elongated portion 38 by an adhesive and the backsheet 40 are attached together to form side flaps 24. 优选的是,在含有侧翼24(如形成凸缘76的那些部分)的顶片38和底片40的伸长部分的整个界面上用可伸长的粘合剂例如Fuller粘合剂2352的连续层而将所述顶片38和底片40连接到一起。 Preferably, the topsheet 24 comprises flaps (such as those forming part of the flange 76) of the elongated portion of the entire interface 38 and the backsheet 40 using an adhesive such as Fuller extensible adhesive 2352 is a continuous layer and the topsheet 38 and backsheet 40 are connected together.

侧翼24可以呈任何合适的构型。 Flaps 24 may be in any suitable configuration. 合适的侧翼公开在1993年4月27日颁发的复审证书且授予Van Tilburg的题为“卫生巾”的复审专利B14589876;1987年8月18日授予Van Tilburg的题为“带有侧翼的成型卫生巾”的美国专利4687478;1995年2月14日授予Lavash等人的题为“具有侧翼和不同伸长区的吸湿用品”的美国专利5389094;和1996年10月3日以Lash等人的名义申请的题为“具有带阶梯式结构和可伸长区的侧翼的吸湿用品”的国际专利申请序号PCT US96/15957中。 Right wing public review certificate in 1993 issued April 27 and issued to Van Tilburg, entitled "Sanitary Napkin" patent reexamination B14589876; 1987 years 8 Yue 18, issued to Van Tilburg, entitled "Health molding with flanking towel, "US Patent 4,687,478; February 14, 1995 granted to Lavash, et al., entitled" absorbent article having a different wing and elongation zone, "US Patent 5,389,094; and in the name of Lash, et al., 1996 October 3 in / 15957 filed entitled "absorbent articles with wings having a stepped structure and the zones of extensibility" international Patent application No. PCT US96.

在优选实施例中,当将侧翼24包在穿用者内衣边缘上时,卫生巾20在消除主体部分22和侧翼24上的应力方面具有几个改进的特性。 In a preferred embodiment, the flaps 24 when the bag to the wearer when the edges of the underwear, the sanitary napkin 20 has several improved characteristics in terms of stresses on the flaps 24 and the main body portion 22 to eliminate.

上述一个改进的特性是主体部分22的中央区36设置横向可伸长性。 Improved characteristics of the one main body 36 is disposed a central region portion 22 of the transverse extensibility. 这使中央区36伸长以有助于侧翼24折叠在穿用者内衣的弯曲侧边。 This elongation of the central region 36 to facilitate folding the side flaps 24 curved sides of the wearer's undergarment. 如图1所示,横向伸长性还优选从主体部分22的中央区36横向向外延伸到主体部分22的纵向侧缘26之外并进入侧翼24。 As shown in FIG. 1, the transverse extensibility also preferably extends laterally from the central region 36 of body portion 22 outward to the body portion longitudinal edges 22 and 26 into the outside flank 24. 在图中所示的实施例中,该横向伸长区优选终止在环绕侧翼粘合剂82的区域70。 The embodiment shown in the figures, the laterally elongated region preferably terminates in a region 70 surrounding the adhesive flaps 82. 优选使围绕侧翼粘合剂的区域70的挺度大于侧翼24的其余部分的挺度以便有助于消费者使用该产品时能方便地调整侧翼。 Can easily adjust the flanking regions surrounding the flanking preferable that when the adhesive 70 is greater than the stiffness of the stiffness of the remainder of the side flaps 24 to facilitate consumer use of the product.

另一个改进的特性是在图中所示的实施例中,即使侧翼24与主体部分22构成一体,它们还具有源于卫生巾20中吸湿芯42的纵向侧缘42A内侧某一点的可伸长区72(即,在第二和第三可伸长区46和48内)。 Another feature is the improved embodiment illustrated in the figures, even if the side flaps 24 formed integrally with the body portion 22, they also have longitudinal side edges 42 of the sanitary napkin from the inner side 42A of the absorbent core 20 may be a point elongation region 72 (i.e., at 48 and the second and third zones of extensibility 46). 由于某些原因,理想的是使可伸长区72位于吸湿芯42纵向侧缘42A的内侧。 For some reason, it is desirable that the zones of extensibility 72 may be positioned inside the longitudinal side 42 of the absorbent core edges 42A. 首先,通过启动吸湿芯42的纵向侧缘42A内侧的伸长性,而使侧翼24上产生的伸长总量相对于所有伸长性均处于吸湿芯42横向外侧的侧翼明显增大。 First, by starting the elongation of the inner longitudinal edges 42A of the absorbent core 42, the total elongation occurring on the flank 24 with respect to all stretchable side flaps are in a laterally outwardly of the absorbent core 42 significantly increased. 其次,当将伸长性设在吸湿芯42纵向侧缘42A的内侧时,所述伸长性能更有效地适应各种紧身短衬裤尺寸和式样。 Then, when the elongation of the longitudinal sides 42 provided on the inner side edges 42A of the absorbent core, the elongation properties more effectively adapt to various panty sizes and styles. 使具有整体侧翼的卫生巾在吸湿芯边缘内侧具有可伸长性的困难之处在于吸湿芯通常既不能伸长又太厚以致于无法在其中形成可变形网状区。 The sanitary napkin with side flaps integral with the difficulties of extensibility of the absorbent core that typically both inextensible and too thick to be formed which can not be deformed in a mesh region inside the absorbent core edge. 然而,在图中所示的实施例中,通过使用可伸长吸湿芯42而克服了这些困难,所述吸湿芯被顶片38和底片40包围,顶片38和底片40中都形成有所需的可伸长区,而且将顶片38和底片40连接在一起。 However, in the embodiment shown in the figures, through the use of an elongated absorbent core 42 overcomes these difficulties, the absorbent core is surrounded by the topsheet 40 and backsheet 38, the topsheet 38 and the backsheet 40 have been formed the zones of extensibility required, and the backsheet 38 and the topsheet 40 are joined together.

顶片和底片的可伸长部分与直接位于底片40中的可变形网状区上的顶片38中的可变形网状区垂直对齐。 38 mesh deformable region and the extensible portions of the topsheet on the backsheet and the topsheet 40 directly to the backsheet in a region vertically aligned with the deformable mesh. 可以将顶片38和底片40的可伸长部分连接到吸湿芯42上并使其与吸湿芯一起伸长。 The topsheet 38 and backsheet 40 is extensible part may be attached to the absorbent core 42 and allowed to elongate with the absorbent core. 此外,可以在这些区域中将顶片38和底片40中的一个或两个都不与吸湿芯42相连。 Further, in the top sheet 38 and backsheet 40 or one of the two are not connected to the absorbent core 42 in these regions. 优选的是,在这些区域中,至少不将底片40连接到吸湿芯42上。 Preferably, in these regions, at least not to the absorbent core 42 attached to the backsheet 40.

在图中所示的实施例中,卫生巾20的再一个改进的特性是在侧翼24的角区86和主体部分22的邻接部分(第二和第三可伸长区46和48)中的主伸长矢量分量的方向。 In the embodiment shown in FIG embodiment, the sanitary napkin 20 in a further improved properties in the abutting portion (the second and third regions of extensibility 46 and 48) flanking the corner regions 86 and 24 of the main body portion 22 in main elongated direction of the vector component. 当用平面图示出卫生巾20时,侧翼的角区86出现在侧翼24的外缘与主体部分22的纵向侧缘26交叉的地方。 When a plan view showing the sanitary napkin 20, 86 flanking the corner regions occur where the outer edge of the flaps 24 with the main body portion 22 of the longitudinal side edges 26 intersect. 角区86不仅包括这些角,而且还包括侧翼24边缘内侧的周边区域和相邻区域。 Corner regions 86 include not only these corners, but also the peripheral region of the inner flank 24 and the adjacent edge regions. 在这些边缘的交叉处,不必形成锐角或表示锐角的分界线。 At the intersection of these edges, not necessary to form an acute angle or an acute angle represented by the boundary line. 在授予Lavash等人的美国专利5389094中包含了对带有侧翼的卫生巾的角区的更详细的描述。 Contains a description of the corner regions of the sanitary napkin with side flaps issued to Lavash more detail in U.S. Patent No. 5,389,094, et al. In. 图1中所示实施例的角区86与可伸长区72处于同一区域中。 Corner area in the embodiment shown in FIG 86 and the zones of extensibility 72 in the same zone.

在各实施例中角区86内可伸长性的主矢量分量的方向可以主要在横向上、主要在纵向上、或在横向和纵向之间的方向上。 Major vector component in the direction of the corner area in each Example extensibility 86 may be in the transverse direction, primarily the main direction in the longitudinal direction or between the horizontal and vertical. 在图中所示的优选实施例中,角区86内主伸长矢量分量的方向优选与主体部分22的相邻的可伸长区处于相同的方向上。 In a preferred embodiment shown in FIG embodiment, the adjacent zones of extensibility 86 in the direction of the primary vector component preferably elongated body portion 22 of the corner regions in the same direction. 相邻的可伸长区是第二或第三可伸长区46和48。 The zones of extensibility adjacent the second or third regions of extensibility 46 and 48. 由于这两个可伸长区优选为对称形式,所以相对于每个侧翼24的两个角区86而言,这个主矢量分量的相对方向通常是相同的。 Since these two zones of extensibility preferably symmetrical form, so that with respect to the two flaps 24 of each corner region 86, the opposing direction of the primary vector component that is generally the same. 术语“相对方向”是指主矢量分量与纵向中线L之间的角度。 The term "relative direction" refers to the angle between the major vector component of the longitudinal centerline L. 因此,角区86的主伸长矢量分量的相对方向是向内朝卫生巾20的横向中线T成角度A。 Accordingly, the relative direction of the primary vector component of elongated corner regions 86 inwardly toward the transverse centerline T of the sanitary napkin 20 at an angle A.

在角区86中使主伸长矢量分量向内定向具有许多优点。 In the corner regions 86 the main manipulation inwardly directed elongate vector component has many advantages. 可伸长性设计成当将侧翼折叠到穿用者内衣的弯曲边缘上时,能比先前为解决这一问题而作出的许多尝试更有效地消除侧翼24上的应力。 Many try extensibility on the flaps are designed to fold when the wearer's undergarment curved edge, can be previously made to solve this problem more effectively eliminate the stresses on the flaps 24. 特别是,当将侧翼24包到穿用者内衣裆区的弯曲边缘上时,伸长性能解决因作用在卫生巾20的主体部分22和侧翼24上的力引起的问题。 In particular, when the flaps 24 to the curved edge of the package to the crotch of the wearer, caused by elongation properties in solution and by the action of the force on the flaps 24 of the sanitary napkin 20 of the body portion 22 of the problems.

在此要解决的所述伸长性定向的一个问题涉及护翼或侧翼“脱开”(“popoff”)。 One problem of the orientation of the elongated herein relates to Solve wings or flaps "disengage" ( "popoff"). 这包括侧翼粘合剂82(下面将更详细地描述),将侧翼粘合剂设计成通过将侧翼24固定到穿用者内衣的下侧或固定到相对的侧翼上而将侧翼24固定到内衣周围。 This includes flanking adhesive 82 (described in more detail below), designed to be flanked by an adhesive 24 secured to the wearer's undergarment or secured to the lower side limb opposing side flaps while the side flaps 24 secured to the undergarment around. 围绕穿用者的内衣侧边折叠侧翼24将会在侧翼上产生张力。 Around the wearer's undergarment folded side flaps 24 will produce tension in the flaps. 该张力使侧翼粘合剂82失去与穿用者内衣下侧或相对的侧翼之间的粘合并且成为非连接的或使两者“脱开”。 The tension causes the flaps to lose adhesive 82 between the wearer's undergarment the adhesive side or the opposing side flaps and becomes lower so that the two non-connected, or "release." 试图防止护翼脱开的一种方式是增加侧翼粘合剂82的强度。 One way to attempt to prevent disengagement of the flaps are flaps to increase the strength of the adhesive 82. 然而,增加侧翼粘合剂82的强度可能会导致其它问题。 However, increasing the adhesive strength of the side flaps 82 may cause other problems.

在此所述需解决的伸长性定向的另一个问题是由于围绕穿用者内衣侧边折叠侧翼24而产生的张力也在卫生巾20的主体部分22上施加了张力。 Another problem oriented extensibility described herein to be solved is due to the tension of the folded side flaps 24 around the sides of the wearer's undergarment the sanitary napkin also generated tension is applied to the upper portion 22 of the body 20. 这特别与高柔性卫生巾,例如本文所述的可伸长卫生巾有关。 This is particularly high flexibility of the sanitary napkin, such as the extensible sanitary napkin described herein related. 通过叠起侧翼24而施加到主体部分22上的张力会使主体部分22的端区32和34与固定到穿用者内衣上的粘合剂脱离。 24 applied by flaps folded to make the tension on the body portion 22 of the body portion 22 of the end region 32 and 34 fixed to the wearer's undergarment from adhesive. 这将导致主体部分22的端缘28折到或卷到主体部分22其它部分的顶部。 This will cause the end edge of the body portion 22 to fold or roll 28 to the top of other parts of the body portion 22.

图6中示出了因折叠侧翼24而产生的张力引起的高柔性卫生巾中的另一个问题。 Figure 6 shows a highly flexible sanitary napkin another problem caused by tension generated due to the folding flaps 24 in. 图6表示一个高柔性卫生巾20。 Figure 6 shows a highly flexible sanitary napkin 20. 尽管应理解的是,卫生巾20具有侧翼,但是在图6中为了简化起见而未示出侧翼,这是因为我们感兴趣的主要是力对主体部分22的影响。 While it is understood that the sanitary napkin has side flaps 20, but in FIG. 6 for simplicity not shown flank, because we are interested primarily influence the body portion 22. 如图6中所示,因折叠侧翼24而产生的张力能把主体部分22一端或两端向内拉向横向中线并使主体部分22的各部分彼此折叠。 As shown in FIG. 6, the tension can body portion by folding the flaps 24 and 22 to produce one or both ends and pulled inwardly toward the transverse center line of each folded portion of the body portion 22 to each other. 卫生巾中面对衣物侧20B上的紧身短衬裤固定粘合剂使折起的部分粘合到主体部分22的下部。 Face of panty fastening adhesive on the garment side 20B so that the folded portion is adhered to a lower body portion 22 of the sanitary napkin. 从主体部分所取的形状看,在此可以将这种折叠称为“Z形折叠”。 From the shape of the body portion, taken to see where this may be referred to as a folded "Z-fold."

在角区86中主伸长矢量分量的方向基本上可以减小或消除这些问题。 In the corner regions 86 in the direction of the primary vector component of the elongation can be substantially reduced or eliminated these problems. 已经确定,这些问题中的大多数可归因于施加在主体部分22的端区和通过侧翼粘合剂82固定的侧翼24的某些部分之间的张力。 It has been determined that most of these problems are attributable to application of the body portion 22 and end region flanked by the adhesive tension between certain portions of flaps 24 of 82 fixed. 在角区86中主伸长矢量分量的方向优选为通常平行于卫生巾上这些部分之间的张力线的方向。 Main elongated vector component in the direction of the corner area 86 is preferably generally parallel to the portion of the sanitary napkin between the direction of the tension line. 这种伸长性减小了主体部分22的端区和由侧翼粘合剂82固定的侧翼24某些部分之间的张力。 This extensibility reduces the tension between the end regions of the main body portion 22 and certain portions of flaps 82 is fixed by a wing adhesive 24. 此外,与第二和第三可伸长区的伸长方向相同,角区86的伸长方向也朝着侧翼横向中线T1向内定向。 Further, the direction of elongation of the second and third zones of extensibility of the same, the elongation direction of the corner area 86 is also oriented inwardly toward the transverse centerline flanking T1. 一些先前的努力旨在将侧翼的可伸长部分定向在与穿用者的紧身短衬裤松紧带相同的伸长方向上。 Some previous efforts aimed at orienting the extensible part of the flanking panty elastics wearer the same direction of elongation. 所述卫生巾所具有的伸长性处于与穿用者的紧身短衬裤松紧带交叉的方向而且更接近于垂直于所述松紧带的方向上。 The sanitary napkin has extensibility in the direction of the wearer's panty elastics and closer to the intersecting direction perpendicular to the elastic band.

应注意的是,在图中所示的优选实施例中,由于角区86和第二及第三可伸长区46、48中形成可变形网状区,所以优选使角区86和第二及第三可伸长区46、48可弹性伸长。 It is noted that, in the preferred embodiment shown in FIG embodiment, by forming the deformable mesh regions 46, 48 and the corner area 86 the second and third zones of extensibility, it is preferable that the corner regions 86 and the second and third zones of extensibility 46, 48 may be elastically stretchable. 这是在没有将传统的松紧带固定到含有卫生巾这些部分的材料中的情况下实现的。 This is not the traditional elastic is secured to the sanitary napkins contained implemented in the case of these portions. 此外,伸长性较小的带区(第一网状区)不会以使侧翼折叠到吸湿芯下面的方式在卫生巾的这些区域上施加张力。 Further, elongation of the smaller band (first mesh region) will not cause the absorbent core to the side flaps folded in the following manner applying tension on these regions of the napkin.

优选使图中所示卫生巾20侧翼上的角区86与相邻的第二和第三可伸长区46、48一起在给定的力作用下在平行于其中第一网状区64的方向上伸长以下量:在小于或等于约75克力的作用下伸长5%;在小于或等于约150克力的作用下伸长10%;在小于或等于约175克力的作用下伸长15%;和在小于或等于约250克力的作用下伸长25%。 Preferably on the corner regions flanking the sanitary napkin 20 shown in FIG. 86 adjacent the second and third zones of extensibility 46, 48 together under a given force acting parallel to the region where the first mesh 64 elongation direction following amounts: 5% elongation under the effect of less than or equal to about 75 grams; and 10% elongation under the effect of less than or equal to about 150 grams; the role of less than or equal to about 175 grams of the elongation 15%; and 25% elongation under the effect of less than or equal to about 250 grams force. 优选使实施例中示出的侧翼24的角区86和相邻的第二及第三可伸长区46、48可弹性伸长。 Preferred embodiment shown that the flaps 86 and the corner regions 24 of the adjacent second and third zones of extensibility 46, 48 may be elastically extensible embodiment. 图中所示的侧翼24的角区86和相邻的第二及第三可伸长区46、48在伸长后可以有少量永久变形(约达10%)。 FIG flaps 24 in the corner area 86 and an adjacent second and third zones of extensibility 46 may be stretched after a small amount of set (up to about 10%).

图中所示侧翼24可以有多种可供选择的实施例。 Flanking shown in FIG. 24 can have a variety of alternative embodiments. 在(不太优选的)实施例中,侧翼24的角区并不具有本文所述的向内定向的伸长性,而是可以具有可在横向上整体伸长、在纵向上整体伸长或在纵向和横向之间的方向上向外伸长的区域。 In (less preferred) embodiment, the angle of the flank region 24 does not have inwardly directed extensibility described herein, but may be integral with elongated in the transverse direction, elongated in the longitudinal direction or the whole in a direction between the longitudinal and transverse elongate areas outwardly. 此外,在不太优选的实施例中,还可以将含有可变形网第一区64的伸长性较小的带从侧翼的角区86中除去。 Further, in a less preferred embodiment, also be stretchable strainable network comprising a first region 64 of the smaller band is removed from the corner region 86 of the flank. 还可以从卫生巾的其它部分包括主体部分22中除去伸长性较小的带区。 Removing the body portion may further include an elongated region 22 of a smaller band from the other parts of the sanitary napkin. 对于本文描述的用在传统的不可伸长吸湿用品中的护翼也落入本发明的范围内。 For flaps used in conventional non-extensible absorbent articles described herein are also within the scope of the invention.
