Description

失禁用吸收垫 Incontinence absorbent pad

本发明涉及薄而且紧凑的失禁用吸收垫,更具体地说,涉及需施加于使用者裆部以解决他或她的轻微失禁现象的失禁用吸收垫。 The present invention relates to a thin and compact absorbent incontinent pads, and more particularly, relates to the need to solve the crotch portion applied to the user his or her incontinence phenomena light incontinence absorbent pad. 文中所采用的术语“失禁用吸收垫”总的指供失禁者使用的吸收制品,包括被称作吸收片、吸收衬垫或吸收卡的所有制品。 The term used herein "absorbent incontinent pad" refers to the total absorbent articles for incontinence use, all referred absorbent article comprising a sheet, the absorbent pad or absorbent card. 为简便起见,按照排尿量,文中所用的术语“轻微失禁”是指排尿量为250cc或更少的情况,与之相对,术语“严重失禁”是指排尿量更大的情况。 For simplicity, in accordance with the urine output, as used herein, the term "light incontinence" refers to urine output is 250cc or less, the contrast, the term "severe incontinence" refers to the case where more urine production.

近年来,专门设计用于成人的轻微失禁现象的卫生制品已经越来越为市场所瞩目,很多厂商积极地致力于此类产品的开发。 In recent years, the phenomenon of light incontinence specially designed for adult hygiene products market has increasingly attracted the attention of many manufacturers actively committed to the development of such products. 轻微失禁的症状更常见于女性,失禁的程度可以从最轻微的(15cc或更少)到中等轻微的(大约200cc),遭受该症状折磨的年龄段为20岁到50岁。 Symptoms of mild incontinence is more common in women, the degree of incontinence can range from the most minor (15cc or less) to moderate slightly (about 200cc), suffering from the symptoms of torture age of 20 years old to 50 years old. 迄今为止,只有相当少的一些产品是专门为解决成人的轻微失禁症状来设计的,只是用诸如卫生巾和底裤(panty shields)之类的其它制品来作为代用品。 So far, only a relatively small number of products is designed to address the symptoms of mild incontinence in adults to design, but with such as sanitary napkins and underwear (panty shields) other products such as substitute.

诸如卫生巾和底裤之类的制品原来是为处理月经血设计的,因而在用于解决尿失禁问题时会遇到很多问题。 Products such as sanitary napkins and underwear like was originally designed for the treatment of menstrual blood, and thus will encounter many problems to solve incontinence problems. 业已发现,目前采用木纸浆制作的、为解决轻微尿失禁而设计的制品也会导致很多问题。 It has been found that the current use of wood pulp production, in order to solve minor incontinence designed products can also cause a lot of problems.

其中一个问题是,目前用来处理轻微失禁的制品有渗漏和不舒适的问题,通常会导致粘滞的感觉,因为它们不能提供足够的吸收和性能。 One problem is that, currently used to treat minor leakage and incontinence products are not a question of comfort, usually leads to feeling sticky, because they do not provide sufficient absorption and performance. 导致这些和其它问题的一个原因是,在婴儿尿片和成人失禁用尿片中,一个很重要的特征是,可以快速地吸收被一次排出的大量排出液体。 One of the reasons leading to these and other problems is that in baby diapers and adult incontinence diapers, a very important feature is that a large number of discharged liquid can be absorbed quickly discharged once. 这已知为“收集”作用。 This effect is known as "collection." 相反,设计用于轻微失禁症状的制品必须能高效地和有效地处理通常较少量的、但次数频繁的排出液体。 In contrast, designed for light incontinence symptoms article must be efficiently and effectively processing typically lesser amount, but the number of liquid discharging frequent. 按照婴儿尿片和成人失禁尿片设计的成人轻微失禁用制品通常采用木纸浆绒毛(wood pulp fluff)来作为其主要成分。 According to baby diapers and adult incontinence diapers designed for adults with mild incontinence products commonly used wood pulp fluff (wood pulp fluff) as its main component. 当被用于解决成人轻微失禁时,木纸浆绒毛的表面会保持润湿,使佩戴者的与该吸收制品接触的皮肤发生皮疹或发炎。 When used to solve minor adult incontinence, wood pulp fluff surface will remain wetted, in contact with the skin of the wearer of the absorbent article or inflamed rash.

为解决这些问题,希望设计出一种能利用超级吸收聚合物(SAP)之性能的成人轻微失禁用制品,所述超级吸收聚合物在使液体排出物成胶质化时具有优良的性能。 To solve these problems, it is desirable to design an adult can use one kind of performance superabsorbent polymer (SAP) of slightly incontinent article, the superabsorbent polymer having excellent performance when the liquid effluent of glioblastoma. 还有较佳的是,这样的吸收制品具有较高成分的SAP,最好是含有几乎100%的SAP。 Also preferably, the absorbent article such SAP component having a high, preferably contain almost 100% of the SAP.

目前吸收制品的第二个问题是,吸收制品在使用过程中总是润湿的。 At present the second issue of the absorbent article is an absorbent article during use is always moistened. 为解决这一问题,关键是要获得一个具有透气性的结构,以便在使用过程中保持可透气,不会变得不舒服、不通气。 To solve this problem, the key is to obtain a structure having gas permeability, in order to maintain breathable during use, it does not become uncomfortable stuffiness. 为了实现这样的结构,不但是诸如上片(表面片)和背衬片之类的构件必须是透气的,而且吸收制品本身必须具有一种透气的结构。 To achieve such a structure, not only such as a topsheet (surface sheet) and the backing sheet or the like must be air-permeable member, and the absorbent article must themselves have a breathable structure.

成人轻微失禁用制品所必须解决的第三个问题是,遭受轻微失禁症状困扰的人们通常是不定期地、瞬间地发病,使病人时刻保持高度紧张状态。 Adults with mild incontinence products must solve the third problem is that the symptoms suffered minor incontinence is often plagued by people from time to time, instantaneously disease, in which patients keep high state of tension. 例如,轻微失禁经常会由于正常怀孕所导致的腹部压力变化而产生,或者由于打喷嚏、突然大笑或身体运动(如跳跃)而造成。 For example, slight incontinence is often due to abdominal pressure changes caused by normal pregnancy and produce, or due to sneezing, laughing, or sudden body movements (such as jumping) caused. 换言之,失禁的症状经常会发生于正常而且健康地生活着的女性。 In other words, the symptoms of incontinence often occurs in women of normal and healthy to live in. 因此,非常重要的是,失禁用制品可以尽量不为人注意地佩戴,并采取非常薄而且紧凑的形式,以便于使另外的或闲置不用的制品可以放在手提包或口袋中加以携带。 Therefore, it is important that incontinence article may be worn as much as possible unnoticed, and take the form of a very thin and compact, so as to cause additional idle or article can be placed to be carried in a handbag or pocket.

失禁用制品所必须解决的第四个问题是,使用者会有各种不同的形状和尺寸。 Incontinent articles fourth problem which must be resolved is that the user will have a variety of different shapes and sizes. 一种吸收制品必须具有适合于佩戴者人体区域的各种不同形状的三维(立体)适应性。 An absorbent article must be adapted to a three-dimensional region of a wearer's body in a variety of different shapes (dimensional) adaptability.

下面将结合附图来描述本发明的若干个实施例。 It will be described several embodiments of the present invention in conjunction with the following drawings.

图1示出了根据本发明的一个设计用于少量尿液的失禁用吸收垫的实施例。 FIG 1 illustrates an embodiment of the present invention is designed for the small amount of urine incontinence absorbent pad. 在图1中,标号1表示一上片,标号2表示一背衬片。 In Figure 1, reference numeral 1 denotes a topsheet, reference numeral 2 denotes a backing sheet. 上片1由诸如多孔非织造织物或穿孔薄膜之类的材料片制成,这种材料片可透液、透气。 Topsheet is made of a porous non-woven fabric sheet or a perforated film of a material such as a sheet of such material may be liquid-permeable, breathable. 背衬片2最好是用可以让空气和水气通过但不能让水分通过的多孔薄膜制成,或者是由一层或多层这样的薄膜与一层或多层非织造织物粘接成的层叠物。 The backing sheet 2 is preferably allows air and moisture but does not allow water to pass through a porous film made of, or by such a film with an adhesive layer or layers one or more layers of nonwoven fabric to laminate. 或者,背衬片2可以包括由聚乙烯或聚丙烯的非织造织物制成的防水层叠物构成,例如纺丝粘合—熔喷—纺丝粘合(SMS)或纺丝粘合—熔喷—熔喷—纺丝粘合(SMMS)的织物。 Alternatively, backing sheet 2 may comprise a waterproof laminate made of non-woven fabric composed of polyethylene or polypropylene, for example, spunbonded - melt-blown - spunbond (SMS) or spunbonded - melt-blown - melt-blown - spunbond (SMMS) fabric. 在这样一种构造中,可以不必采用如前所述的薄膜。 In such a configuration, the film may not necessarily be employed as described above.

上片1和背衬片2的周边3借助诸如热封合或超声波封合等适当的手段来形成。 The topsheet 3 by means of heat-sealing or suitable means such as an ultrasonic sealing and the backing sheet 2 is formed outside. 此外,在上片1和背衬片2之间夹设有一吸收单元4。 Further, the topsheet 1 and the backing sheet 2 is interposed between an absorption unit 4. 在本发明的一个实施例中,在上片2中间的主吸收区域可以设置凹线,以增强其三维立体结构。 In one embodiment of the present invention, the topsheet 2 in the middle of the main absorbent portion may be provided a concave line, in order to enhance its dimensional structure.

现请参见图2和3,在本发明的一个实施例中,吸收单元可以包括一大致为矩形的非织造织物基片5,在该实施例中,此基片对着背衬片2,并靠近一由多个(图中示出了四个)高吸收层6的条带构成的高吸收区域。 Referring now to Figures 2 and 3, in one embodiment of the present invention, the absorbent unit may comprise a generally rectangular nonwoven fabric substrate 5, in this embodiment, the backing sheet against the substrate 2, and close to a plurality (four shown in the figure) high absorption layer is constituted with a strip of high absorbing regions 6. 在各高吸收层条带6之间有间隙,这些间隙将非织造织物基片5暴露出来。 6 in the gap between the high absorption layer strips, these gaps will nonwoven fabric substrate 5 is exposed. 在该实施例中,吸收单元4具有由高吸收层6以及不含有高吸收层的区域所构成的吸收区域,后者将高吸收层6分开,并形成了一个能让空气流入非织造织物基片5的透气区域。 In this embodiment, the absorbent nonwoven fabric substrate 4 allows a flow of air into the region of a high absorbent layer 6 and a region not containing the high absorbent layer composed of high-absorbing layer 6 which will separate and form a unit having permeable sheet region 5.

高吸收层6最好主要是由超级吸收聚合物(SAP)制成。 6 is preferably a high absorption layer is mainly made of superabsorbent polymer (SAP). 为了获得尽可能好的紧凑性和吸收性,应该含有尽可能多的SAP成分,最好是达到60%或更高。 In order to obtain the best possible compactness and the absorbent, should contain as much of the SAP component, preferably 60% or higher. 如JPA H10-168230所述,这样的高吸收层6能以商业化的规模来生产,即,利用已知为线式涂敷机的装置来将一种带有颗粒状超级吸收聚合物的弥散液(dispersion liquid)涂敷到一非织造织物的表面上。 As JPA H10-168230, this high absorption layer 6 can be commercial scale production, i.e., a line by a known coater apparatus to the one kind of the particulate superabsorbent polymer with a dispersion of solution (dispersion liquid) is applied onto the surface of a nonwoven fabric.

在本发明的一个较佳实施例中,在吸收单元4和上片1之间夹设了一弥散片7。 In one embodiment of the present invention, preferred embodiments, the topsheet and the absorbent 4 interposed between the unit 1 is provided with a diffusion sheet 7. 该弥散片7由透液的非织造织物构成,其尺寸大致等于吸收单元4。 The diffusion plate 7 is made of liquid-permeable nonwoven fabric having a size substantially equal to the absorption unit 4. 弥散片7可以留住透过上片1而来的液体,并使这些液体向各个方向弥散。 Diffusion sheet 7 may retain a liquid permeable topsheet 1 comes, and that these liquid dispersed in all directions. 弥散片7(也可称之为收集层)可以大于或小于吸收单元4,并且最好是在中心区域更加浓缩。 Diffusion sheet 7 (also called a collector layer) may be larger or smaller than the absorption unit 4, and is preferably more concentrated in the central region. 类似地,在一较佳实施例中,可以在吸收单元4与背衬片2之间夹设一片薄织物(tissue)8。 Similarly, in a preferred embodiment, the absorbent element 4 may be the backing sheet interposed a sheer fabric (tissue) 8 between the two. 薄织物8可以改善液体的弥散性,并提高失禁用吸收垫的尺寸稳定性。 Sheer fabric 8 can improve dispersibility of liquid, and improve the dimensional stability incontinence absorbent pad. 或者,在失禁用吸收垫用于收集非常少量的尿液时,可以省略弥散片7和薄织物8,以使整个结构更加简单。 Alternatively, when the absorbent pad for incontinence of urine collection very small amount, the dispersion can be omitted and the thin fabric sheet 7 8, so that the entire structure is more simple.

虽然在前述实施例中,弥散片7位于吸收单元4和上片1之间,但也可以将这种构造反过来,使上片位于收集片7和吸收单元4之间。 Although in the foregoing embodiment, a diffusion plate 7 is positioned between the topsheet and the absorbent unit 4, but in turn may be configured such that the topsheet and the absorbent sheet 7 is located between the collecting unit 4. 或者,如图7和8所示,可以省略上片7,用收集层7'来代替。 Alternatively, as shown in FIG. 7 and 8, it can be omitted topsheet 7, '7 instead of with the collection layer. 这种实施例的优点是,吸收单元可以膨胀,而其上部不会受到上片1的限制。 An advantage of this embodiment is that the absorbent element may be expanded, while the upper portion is not restricted by the topsheet 1. 用于该目的的收集层最好是重量为大约30g/m2的大体积片材,或者是这种材料的压缩件。 The acquisition layer is preferably used for this purpose bulky sheet weight of about 30g / m2, or compression member of such a material. 例如,可以采用压凹线厚度为1184μ(如Tredegar公司生产和销售的商品名为“X-27373”的产品)的大体积穿孔薄膜。 For example, a thickness of the pressure line recess 1184μ (such as Tredegar Company and sold under the trade name "X-27373" products) bulky perforated film. 还可以采用密度为大约100g/m2的纤维素海棉制的压缩片材,以及密度为50g/m2的中空双组份纤维制的大体积非织造织物。 It may also be employed as the density of the compressed cellulose sponge sheet made of approximately 100g / m2, and density of the bulky nonwoven fabric of 50g / m2 of hollow bicomponent fibers.

在本发明中,高吸收层条带6是还有超级吸收聚合物(SAP)的层。 In the present invention, a high absorption layer tape strip 6 there is the superabsorbent polymer (SAP) layer. 超级吸收聚合物是每单位重量能吸收大量水分的高分子聚合物,大致包括羧甲基纤维素、丙烯酸及其盐类、交联的丙烯酸酯聚合物、淀粉—丙烯酸接枝共聚物、淀粉—丙烯腈接枝共聚物的水解产物、交联的聚氧乙烯、交联的羧甲基纤维素、部分交联的水溶胀共聚物例如聚环氧乙烷和聚丙烯酰胺、以及异丁烯马来酸共聚物。 Superabsorbent polymer per unit weight of the polymer can absorb large amounts of water, generally include carboxymethylcellulose, acrylic acid and its salts, crosslinked acrylate polymers, starch - acrylic acid graft copolymer, a starch - hydrolyzate of acrylonitrile graft copolymer, crosslinked polyoxyethylene, crosslinked carboxymethylcellulose, partially crosslinked water-swellable copolymer such as polyethylene oxide and polyacrylamide, and isobutylene-maleic acid copolymer. 通过使这样的共聚物干化,就可以获得微粒基的共聚物。 By drying such copolymers, the copolymer particles can be obtained group. 在干化之后,通常进行后处理以提高共聚物微粒的交联密度,同时添加防粘(antiblocking)剂以防止由于吸收水分而导致产品微粒粘连。 After drying, generally carried out after the treatment to increase the crosslinking density of the copolymer particles, adding at the same time release (Antiblocking) agents to prevent absorption of moisture leading to adhesion product microparticles.

根据本发明构造而成的失禁用吸收垫可以借助吸收单元4的高吸收层6中所包含的超级吸收聚合物的高吸收性而有效地吸收反复排出的、少量的液体,同时令上片1的表面保持干燥。 According to the present invention constructed incontinent absorbent pad may be high absorption by the absorbent layer containing superabsorbent 6 superabsorbent polymer unit 4 effectively absorb a small amount of liquid is repeatedly discharged, so that while the topsheet 1 the surface remains dry. 还有,由于吸收单元4具有位于高吸收层6之间的透气区域,使非织造基片5暴露于空气流,因而进一步有助于使上片1的表面保持干燥状态。 Further, since the absorption unit 4 has a high permeability region between the absorbing layer 6, the nonwoven substrate 5 is exposed to the air flow, thereby further contributing to the surface of the topsheet 1 is maintained in a dry state. 还有,透气区域可以便于弯折和均匀的变形,因而使吸收制品可以三维立体地变形而与佩戴者的身体轮廓相匹配。 Further, the breathable zone may facilitate bending deformation and uniform, thereby making the absorbent article can be deformed three-dimensionally match the contour of the wearer's body. 此外,透气区域还可以充当流体通道,以便高效和快速地将排出液体送往高吸收层6的表面。 In addition, the breathable zone may also serve as a fluid passage, in order to efficiently and quickly fed to the high discharging surface of the liquid absorbing layer 6.

由于根据本发明制作而成的轻微失禁用吸收垫可以通过在马桶中用水冲走或当垃圾仍掉等手段来加以丢弃,因而最好是在制品中使用可生物降解的SAP材料。 Since the present invention is made of slightly incontinent absorbent pad may be washed away by water or SAP material still out when the garbage and other means to be discarded in a toilet, which is preferably in the use of biodegradable articles. 在本领域众所周知的可生物降解材料例如是交联的聚烯烃、交联的羧甲基纤维素(如Gelman的美国专利4,650,716所述)、交联的藻酸、交联的淀粉、以及交联的聚氨基酸。 Well known in the art, for example, the biodegradable material is cross-linked polyolefins, crosslinked carboxymethylcellulose (as described in U.S. Patent No. 4,650,716 Gelman), crosslinked alginic acid, crosslinked starch, and crosslinked poly amino acids. 通过采用超级吸收聚合物和用微原纤化—原纤维成形的纤维素的组合来制造高吸收层6,就可以获得具有较高吸收率的结构。 Producing a high structural absorbing layer 6, can be obtained having a higher absorption rate of a combination of cellulosic fibrils formed - by using a super absorbent polymer and micro fibrillated.

在本发明中,吸收单元4的一个重要组成部分是非织造织物基片5。 In the present invention, an important part of the absorption unit 4, a non-woven fabric substrate 5. 该非织造织物基片可以由总的称之为“非织造织物”的材料构成,如湿法和干法纺粘非织造织物和射流喷网法非织造织物。 The nonwoven fabric substrate may be made of the total material "nonwoven fabric" is referred to, such as wet and dry nonwoven fabric and spunbonded nonwoven spunlaced fabrics. 较佳的是,本发明中所采用的非织造织物的体积要尽可能地大,诸如采用通过使已梳纤维网在水流中缠结而获得的射流喷网法非织造织物,以及通过使已梳纤维网热粘接而获得的热粘非织造织物。 Preferably, the volume of the nonwoven fabric of the present invention to be employed as large as possible, such as using the spunlaced non-woven fabric by passing carded web has been entangled in the water flow is obtained, and by making have thermally bonded carded web obtained by thermal bond nonwoven fabric. 还有,为了提供一种可降解的吸收单元,与上述可生物降解的SAP相结合,最好是选择一可生物降解的纤维素非织造织物或者是可以在含有CMC(羧甲基纤维素)之钙盐的水中分解的纤维素非织造织物来制作非织造织物基片5。 Further, in order to provide a biodegradable absorption unit, the above-described biodegradable SAP combination, a choice is preferably a biodegradable cellulose nonwoven fabric may contain, or CMC (carboxymethylcellulose) decomposition of calcium salts in water to produce a cellulose nonwoven fabric nonwoven fabric substrate 5.

应该理解,这里的术语“可降解的吸收单元”意指不但是一种可降解的吸收单元,而且还包括可以在水中分解的、可生物降解的、可以在肥料中分解或可以在土壤中分解的吸收单元。 It should be understood that the term "degradable absorption unit" means not only a biodegradable absorbing unit, but also can be broken down in the water, biodegradable, or may be decomposed in the soil can be decomposed in Fertilizer the absorption unit. 应该理解,虽然以上已经描述了一种可降解的吸收单元4,但失禁用吸收垫本身作为一个整体可以是可降解的,这可以通过适当地选择上片和背衬片所用的材料来实现。 It should be understood that while the above has been described a biodegradable absorbing unit 4, but the incontinence absorbent pad as a whole may itself be degradable, this may be achieved by appropriately selecting the material of the topsheet and the backing sheet used. 例如,可以借助一由水解性材料制成的吸收单元、一由可在水中分解的非制造织物制成的上片、以及一诸如由部分交联的PVA(聚乙烯醇)之类的材料制成的背衬片来构造一个可完全水解的失禁用吸收垫。 For example, by means of an absorption unit made of a decomposable material, the topsheet material made of a non-manufacturing fabric may decompose in water, and such a partially crosslinked by a PVA (polyvinyl alcohol) or the like into the backing sheet to construct a fully hydrolyzed absorbent incontinence pads. 这样一种可水解的吸收垫可以通过在马桶中用水冲走来加以丢弃。 Such a hydrolyzable absorbent pad can be discarded in a toilet flushed by water.

下面将对本发明中所采用的一些术语下定义。 The following will define some terms used in the present invention.

术语“可在水中分解或可水解的”意指这样一种构成材料,它可以很方便地在冲水马桶的水中分解,并且能以足够的细度弥散而不会导致管道或类似物被堵塞。 The term "decompose in water or hydrolysable" means that a constituent material, which can be easily decomposed in water in flush toilets, and can be finely dispersed to a sufficient degree without causing clogging of the pipe or the like is .

术语“可生物降解”意指这样一种构成材料,它可以通过活生物(例如自然环境中的微生物、真菌、酶)的作用,或者在例如用于制造肥料的人工控制的条件下,分解成安全的、分子量小的材料。 The term "biodegradable" is meant a constituent material, it may act by living organisms (e.g., natural environment of the microorganisms, fungi, enzymes), or under manual control, for example, conditions for the manufacture of fertilizers, broken down into safe, small molecular weight material.

术语“可在肥料中降解”意指这样一种构成材料,它可以通过肥料中的活生物(例如微生物、真菌、酶)的作用分解成安全的、分子量小的材料。 The term "degradable fertilizer" is meant a constituent material, it can be fertilizers living organisms (such as microorganisms, fungi, enzymes) acting safety decomposed into small molecular weight material. 例如,当1份重量(在干燥状态下)的可降解吸收单元被制成100份重量(在润湿状态下)的肥料接种体并在58摄氏度下处理40天时,经此处理之后的可降解吸收单元的重量可减至其原始干重的0%至50%。 For example, when 1 part by weight of biodegradable absorption unit (in the dry state) is made 100 parts by weight of the fertilizer inoculum (in wet state) and for 40 days at 58 ° C, biodegradable after this treatment by weight of the absorption unit can be reduced to its original dry weight of 0-50%.

术语“可在土壤中降解”意指这样一种构成材料,它可以在被埋入土壤时,通过土壤中的微生物、真菌或酶的作用分解成安全的、分子量小的材料。 The term "degradable in soil" is meant a constituent material, it can be buried in the soil at the time, broken down into the soil by the action of the safety microorganisms, fungi or enzymes, low molecular weight material. 例如,当1份重量(在干燥状态下)的可降解吸收单元被埋在农田地面下300cm并保持六个月时,经此处理之后的可降解吸收单元的重量可减至其原始干重的0%至50%。 For example, when 1 part by weight of biodegradable absorption unit (in the dry state) is buried under the ground 300cm farmland and held for six months, the weight of this unit is degraded and absorbed after the treatment can be reduced to its original dry weight 0-50%.

应该理解,上面提到的所有术语对本发明而言是可互换的。 It should be understood that all terms mentioned above for the present invention are interchangeable. 此外,如前所述,所有这些术语都应该被一个总的术语“可降解”所涵盖。 Further, as described above, all of these terms should be a general term "degradable" covered.

下面将结合图4来描述根据本发明第二实施例的一个规则型失禁用吸收垫。 4 will be described in conjunction with FIG absorbent pad in accordance with a rule of the second embodiment of the present invention is incontinence. 在该实施例中,一弥散片7夹设在介于上片1和背衬片2之间的空间内。 In this embodiment, a diffusion plate 7 is interposed in the space between the 1 and the backing sheet 2 interposed between the topsheet. 类似地,在吸收单元4和背衬片2之间的空间内设置了一片薄织物8。 Similarly, a piece of thin fabric 8 disposed in the space between the backing sheet 4 and the absorption unit. 吸收片7和薄织物8是定位成可以提高液体的弥散度和失禁用吸收垫的整体尺寸稳定性。 Sheer fabric sheet 7 and the absorbent 8 is positioned to be improved and the overall size of the dispersion stability of the liquid absorbent incontinent pads. 该结构类似于图1至3中所示的第一实施例的结构,但是在几个方面有区别。 Structure of the first embodiment 1-3 is similar to the structure shown in the FIG., But differ in several respects. 其中一个区别之处是,在背衬片2的外周边3上粘接了一边缘构件10,一弹性件11连接于边缘构件10的内周边,藉以使边缘构件10向内延伸。 One difference is that the adhesive edge of a member on the outer periphery of the backing sheet 2 310, an elastic member 11 is connected to the inner periphery of the edge member 10, whereby the edge member 10 extending inwardly.

图5示出了图4中的吸收单元4。 FIG 5 shows an absorption unit 4 in FIG. 4. 该吸收单元4具有一大致为矩形的非织造织物基片5。 The absorbent unit 4 has a substantially rectangular nonwoven fabric substrate 5. 第一吸收区域A靠近非织造织物基片5的中间区域。 A first absorption zone near the center region of the nonwoven fabric substrate 5. 该第一吸收区域A是由相互平行的三个高吸收层条带6组成的,这三个条带之间由狭窄的透气区域C1相间隔。 The first absorbent region A is composed of three mutually parallel with a high absorption layer 6 composed of strips, between these strips three spaced by a narrow air-permeable region C1. 一对由高吸收层6构成的第二吸收区域B位于第一吸收区域A的两侧,其中的高吸收层6平行于第一吸收区域A中的吸收层。 It constitutes a secondary absorption zone by a high absorption layer 6 located on both sides of the first absorption zone B A high absorbing layer 6 which is parallel to the first absorbent layer absorbent region A. 较宽的透气区域C2使第二吸收区域B与第一吸收区域A相间隔。 Wide breathable zone C2 of the second absorption zone to the first absorption zone A B spaced.

第一吸收区域A的宽度Aw相对于第二吸收区域B的宽度Bw的比值最好是在1∶0.3-2的范围内,最好是在1∶0.7-1.0的范围内。 A first absorption zone width Aw ratio of the width Bw of the second absorption zone with respect to B is preferably in the range 1:0.3-2, preferably in the range of 1:0.7-1.0. 还有,较佳的是,将第一和第二吸收区域A和B分开的透气区域C2占据了吸收单元总面积的10%或更多,最好是15%-50%。 Also, preferably, the first and second regions A and B separated absorption breathable area C2 occupy 10% of total area of ​​the absorption cell or more, preferably 15% -50%.

由于将第一吸收区域A布置在中间,而将第二吸收区域B布置在第一吸收区域A的两侧,更便于在各个区域内获得不同的吸收特性,并且更便于剪裁制作具有不同特性、能满足不同需要的产品。 Since the first absorbent region A is disposed in the middle and the second absorption zone B disposed at both sides of the first absorption zone A, easier to obtain different absorption characteristics in each region, and making it easier to cut having different characteristics, to meet the needs of different products. 同时,该实施例还提供了一种可以很方便地改换其形式的结构。 Meanwhile, this embodiment further provides a change which can easily form a structure.

此外,当失禁用吸收垫在失禁尿液的作用下变得湿润的情况下,透气区域C1和C2可以使失禁用吸收垫具有极佳的透气性,防止吸收垫变热、不通气或有其它让人感到不舒服的情况。 Further, in the case where the absorbent pad for incontinence of urine incontinence under the effect becomes wet, C1 and C2 breathable zone incontinence absorbent pad can have excellent air permeability, preventing the absorbent pad to heat, or other air-impermeable make people feel uncomfortable situation.

现请参见图4,一热封件9将吸收单元4联系于其它构件,如弥散片7、薄织物8、上片1和背衬片2,并使所有这些构件形成为一体。 Referring now to Figure 4, a heat sealing member 9 contact the absorbent unit 4 from other components, such as a diffusion sheet 7, 8 a thin fabric, a topsheet and the backing sheet 2, and all of these members are formed integrally. 这样形成一体的吸收单元4被固定到位,吸收单元4和失禁用吸收垫保持它们原来的形状。 Such integrally formed absorbing unit 4 is fixed in place, the absorption unit and incontinence absorbent pad 4 retain their original shape. 还有,该热封件9可提供一让液体向上和向下流动的通道,特别是可以充当使液体从上片向下朝着薄织物层8流动的短通道。 Further, the heat seal member 9 may be provided so that a passage of liquid upward and downward flow, in particular from the topsheet may function as the liquid downwardly toward the short channel thin fabric layer 8 flows.

图6示出了本发明的第三实施例,其中按照本发明设计的一个失禁用吸收垫可以在较长的一段时间内吸收更多的液体。 Figure 6 shows a third embodiment of the present invention, wherein the present invention is designed according to one of incontinent absorbent pad may absorb more fluid over a long period of time. 在该实施例中,有两个吸收单元4a和4b(即双结构吸收单元),每个单元均具有类似于图4所示实施例的结构。 In this embodiment, there are two absorption units 4a and 4b (i.e., the double structure of the absorbent unit), each unit having a configuration similar to the embodiment shown in Figure 4. 图6所示的其它构件类似于图4所示的失禁用吸收垫的构件,并用相同的标号来表示,因而不再赘述。 Incontinence other components shown in Figure 4 shown in FIG. 6 is similar absorbent pad member, and denoted by the same reference numerals, and thus will not be repeated.

图6所示的实施例具有很高的吸收能力,同时又能维持很好的透气性。 Embodiment shown in FIG. 6 embodiment has high absorption capacity, while maintaining good breathability. 在该实施例中,弥散片7位于上片1和上非织造织物基片5之间,但也可以是上片1位于非织造织物基片5和弥散片7之间。 In this embodiment, the diffusion sheet 7 positioned between the topsheet 1 and the nonwoven fabric substrate 5, but may be between the topsheet 15 and the diffusion plate is positioned nonwoven fabric substrate 7.

在本发明的另一个实施例中,如图7所示,两个吸收片4a和4b借助在两个点上的热封件9连接在一起,并由一背衬片2以这样一种方式加以包覆,即,最上面的吸收片4a的上表面未被覆盖,背衬片2具有沿其周边的弹性带子12和13。 In another embodiment of the present invention, as shown, two absorbent sheets 4a and 4b by means of the heat seal at two points 9 7 connected together by a backing sheet 2 in such a manner to be coated, i.e., on the uppermost surface of the absorbent sheet 4a is uncovered, the backing sheet 2 having the elastic band along its perimeter 12 and 13. 在最上面的吸收片4a上设置了一个收集层7',该收集层覆盖了未被背衬片2覆盖之表面的一部分或全部。 On the uppermost sheet 4a is provided an absorbent acquisition layer 7 ', the collector layer covers part or all of the backing sheet is not covered with the second surface of the.

如图7所示的实施例可以如图8所示的那样加以变化。 Example embodiment illustrated in Figure 7 can be varied as shown in FIG. 8. 在图8中,成对的吸收片4a和4b完全被一弥散片14包封。 In FIG. 8, the pair of the absorbent sheets 4a and 4b are completely encapsulated a diffusion plate 14. 如前述实施例一样,一在其外周边上具有弹性带子12和13的背衬片2包围吸收片4a和4b以及弥散片14,只留下弥散片14的一部分未被覆盖。 As in the previous embodiment, having an elastic band on the outer periphery of the backing sheets 12 and 13 surround the absorbent sheet 2 and 4a and 4b diffusion sheet 14, leaving only a portion of the diffusion plate 14 is uncovered. 一收集层7'覆盖于弥散片14之暴露部分的一部分或全部。 A collector layer 7 'to cover a portion or all of the exposed portion 14 of the diffusion sheet.

在图7和8所示的实施例中,省略了上片,只有一收集层7'直接地或通过弥散片14邻接于最上面的吸收单元4a。 In FIGS. 7 and 8 in the embodiment shown, the topsheet is omitted, and only a gettering layer 7 'directly or through a diffusion plate 14 adjacent to the uppermost absorption unit 4a. 这种布置的优点是,一个或两个吸收单元可以胀大或膨胀而不受在其上表面上的上片的限制。 The advantage of this arrangement is that the absorption of one or two units may swell or expand without limitation topsheet on its upper surface. 在这两个实施例中,较佳的是,收集层是用密度为30g/m2或更高的大体积片材,或者是这样一种材料的压缩片材制成的。 In both embodiments, it is preferred that the acquisition layer with a density of 30g / m2 or more bulky sheet, or made of a compressed sheet material. 这些材料的例子包括压凹线厚度为1184μ(如Tredegar公司生产和销售的商品名为“X-27373”的产品)的大体积穿孔薄膜,或者是密度为大约100g/m2的纤维素海棉制的压缩片材,或者是以及密度为50g/m2的中空双组份纤维制的大体积非织造织物。 Examples of these bulky perforated film materials include debossing line thickness 1184μ (such as Tredegar Company and sold under the trade name "X-27373" of the product), or a density of about 100g / m2 cellulose sponge made the compressed sheet, or a bulk density and a nonwoven fabric made of hollow bicomponent fibers 50g / m2 of.

图9示出了根据本发明另一个实施例的失禁用吸收垫。 Figure 9 shows a further embodiment of the incontinent embodiment of the present invention with the absorbent pad. 该实施例的吸收单元是由两个大致为矩形的非织造织物基片5(如图5所示)构成的。 Absorbing unit of this embodiment is a nonwoven fabric substrate 5 (FIG. 5) two substantially rectangular configuration. 最上面的吸收片4a是由上非织造织物基片5构成的,由四个高吸收层6构成的组附连于其内侧,并在基片上相互平行且对中地延伸。 4a uppermost sheet by the absorbent nonwoven fabric substrate 5 composed of a group of four high absorbing layer 6 attached to its inner side formed of even and parallel to each other on the substrate, and extend to the ground. 此外,最上面的吸收片具有一对外侧的高吸收层6,分别位于内吸收条组的两侧。 Moreover, the uppermost layer of the absorbent sheet has a high absorption of a pair of outer 6, which are located on both sides of the absorbent article group. 下吸收片4b是由一非织造织物基片构成,一对外侧的高吸收层附连于下吸收片4b的对应于最上面吸收片4a的外侧吸收层附连位置的位置。 The absorbent sheet 4b is composed of a nonwoven fabric substrate, a pair of outer layers of high-absorbent sheet is attached to the corresponding 4b is absorbed in the uppermost absorbent layer of the absorbent sheet 4a, the outer attachment position even position. 吸收片4a和4b通过热封件9相互联系,并且可能联系于制品的其它构件。 Absorbent sheets 4a and 4b 9 by heat sealing member contact with each other, and the other member may contact the article.

在图9所示的吸收单元的实施例中,其两侧的吸收能力远高于其中间的吸收能力。 In an embodiment of the absorbent unit shown in Figure 9, both sides of which the absorption capacity is much higher than the absorption capacity of the middle thereof. 在设置热封件9的位置上,可以很方便地弯折或变形。 Heat-sealing member 9 is provided on a position, it can be easily bent or deformed. 这样一种吸收制品可以改变其形状以适应使用者的身体形状,特别适用于使用者不希望从两侧渗漏的情况。 Such an absorbent article can change its shape to conform to the body shape of the user, the user does not wish particularly applicable to the case of leakage from the sides.

在图10所示的吸收单元的另一个实施例中,一第一吸收片4a具有类似于图9所示的结构。 In another absorption unit shown in Figure 10 embodiment, similar to the configuration shown in FIG. 4a having a first absorbent sheet 9. 在第二吸收片4b的中部只有一个高吸收层条6。 In the middle of the second absorbent sheet 4b of the absorbent article has only one layer high-6. 第一和第二吸收片4a和4b通过一热封件9相互联系。 The first and second absorbent sheets 4a and 4b 9 contact each other by a heat seal. 在该实施例中,吸收垫的中部具有很强的吸收能力,并且在中部具有较大的面积,该中部会随着吸收单元吸收液体而膨胀。 In this embodiment, the central absorbent pad having a strong absorption, and having a larger area in the middle of the central unit with the absorption liquid absorption expand.

在吸收单元的另一个实施例中,如图11a所示,该吸收单元包括一第一吸收片4a和一第二吸收片4b,它们的中部通过一热封件9相互粘接。 In another embodiment of the absorption unit, shown in Figure 11a, the absorber unit comprises a first absorbent sheet and a second absorbent sheet 4a 4b, middle thereof bonded to each other by a heat seal 9. 如图11B所示,该实施例的吸收单元在吸收了液体之后会在中线的两侧膨胀。 11B, the absorption unit of this embodiment after expansion on both sides of the absorption liquid will midline.

在采用一个热封件的实施例中,实践中通常是在非织造织物基片5的共存内侧上有热熔的纤维材料。 In embodiments employing a heat seal, a common practice is to melt the fibrous material on the inside of the nonwoven fabric coexist substrate 5. 然而,在非织造织物基片5上没有热熔材料的实施例中,可以采用诸如热熔粘合剂之类的粘合剂来粘接非织造织物基片5。 However, no embodiment of the hot melt material, a binder may be employed, such as a hot melt adhesive or the like adhered to the nonwoven fabric substrate 5 on the nonwoven fabric substrate 5.

图10示出了吸收单元的另一个实施例,其中第一吸收片4a和第二吸收片4b通过一夹设于两者之间的热熔粘合剂层10相互粘接。 FIG 10 shows another embodiment of the absorption unit, wherein the first absorbent sheets 4a and 4b by a second absorbent sheet sandwiched in between the hot melt adhesive layer 10 bonded to each other. 借助这种粘接,更便于液体向上和向下流动。 With such an adhesive, easier upward and downward flow of liquid.
