Abstract

按照本发明,提供一种卫生巾,它具有襟片和用 于消除当襟片沿着穿戴者的内裤裤裆的边向下折叠 时所产生的应力的应力消除装置。襟片是沿一条连 接线与吸收装置相连接。可以沿连接线或者在襟片 上设置应力消除装置,两种优选的应力消除装置是凹 槽和裂隙。

Description

本发明涉及一次性的吸收物品,具体地说是涉及妇女的卫生巾。特别地,本发明是关于具有襟片和应力消除装置的卫生巾,所说的应力消除装置是用于消除当襟片向下折叠到穿戴者内裤下面时、在该片状物中所产生的应力
用于吸收体液(如月经、尿、粪便)所设计的所有方式和各种吸收物品自然是公知的,特别是具有襟片的卫生巾在文献中已有公开,且在市场上也可以买到。
一般,襟片是从中心吸收装置横向伸展并用来遮盖住穿戴者的内裤裤挡区域的两边,因此,襟片是放在穿戴者的内裤裤挡区域的边沿和穿戴者大腿之间。通常裤片有一个把它固定在穿戴者内裤下侧面的连接装置。
襟片至少有两个用途,之一,襟片防止渗出物弄脏穿戴者内裤的边,之二,襟片有助于卫生巾的稳定不至移位,特别是当襟片被固定到内裤的下侧面时。
具有一般型式的带襟片的卫生巾在下列专利中已被公开,1987年8月18日公布的Van.Tiburg的美国专利4,687,478,名称为“具有襟片的成形卫生巾”,1986年8月26日公布的Mattingly的美国专利4,608,047,名称为“卫生巾的连接装置”,1986年5月20日公布的Van.Tilburg的美国专利4,589,876,名称为“卫生巾”,1981年8月25日公布的McNair的美国专利4,285,343,名称为“卫生巾”,1968年8月20日公布的Rickard的美国专利3,397,697,名称为“用于内裤的一次性卫生遮护装置”,和1957年4月2日公布的Clark的美国专利2,787,271,名称为“卫生巾”。
虽然具有襟片的卫生巾通常被认为比不带襟片的卫生巾对于防止异脏有更好的防护作用,但是带有襟片的卫生巾通常经受到的问题是使它们不能保持最佳效果的问题,该问题是襟片有时会从穿戴者的内裤下侧面脱落开。
当襟片沿穿戴者内裤的边向下折叠时,在襟片上就产生应力,该应力在穿戴者内裤的边上沿襟片从内裤的体侧到内裤的下面弯曲的折叠线上特别高,这些应力当穿戴者坐下或者蹲下时被加大,因为内裤的边被顶着片状物向外拉,由此增加了对这条折叠线的力,当应力太大时,襟片就从内裤上脱开,上面所说的襟片的一部分优点就会丧失。由此,商业界需要一种方案来消除或者至少定减少折叠时在襟片上产生的压力以防止它们从穿戴者内裤上脱开。
因此,本发明的目的是提供一种具有襟片和应力消除装置的卫生巾,所说的应力消除装置用于消除当襟片沿穿戴者内裤裤挡的边向下折叠并被固定到内裤下侧面时在襟片中所产生的应力。
本发明的另一个目的在于提供一种具有襟片的卫生巾,其中,在襟片上或者沿着襟片和卫生巾中心吸收装置之间连接线有一个裂隙,由此消除当襟片折叠时所产生的应力。
本发明的又一个目的在于提供一种具有襟片的卫生巾,其中,在襟片上或者沿襟片和卫生巾的中心吸收装置之间的连接线有一个凹槽,由此,消除当襟片折叠时所产生的应力。
本发明的再一个目的在于提供一种具有襟片的卫生巾,其中,在每个襟片的每个纵向侧至少有一个应力消除装置。
本发明的这些和其它目的在参考下面并且结合附图的说明来考虑时是很易理解的。
按照本发明,提供了一种具有襟片和应力消除装置的卫生巾,所说的应力消除装置用于消除在襟片沿着穿戴者的内裤裤挡的边折叠时在襟片内产生的应力。这种应力消除装置可以沿连接线或者在襟片内提供,两种优选的应力消除装置一种是凹槽、一种是裂隙。

本发明涉及吸收物品,更具体地是涉及妇女的卫生巾,特别是具有襟片和应力消除装置的卫生巾,所说的应力消除装置用于消除当襟片沿穿戴者内裤裤裆叠开并连接到内裤下侧面时在襟片内产生的应力
术语“卫生巾”用在这里是指妇女在贴近阴部区域穿戴的一种物品,用于吸收和容纳人体排出的各种排泄物(例如,血液、月经和尿),并打算在一次使用后被丢弃(亦即,它不准备被清洗,或者按别的方式被复原,或者被再使用)。
图1所示的是本发明一个最佳实施例的卫生巾210。如图1中所见,最佳的卫生巾210基本上包括一个由中心吸收垫212表示的吸收装置和两个襟片224和224′(在以下的讨论中,如无相反地说明,卫生巾都有两个襟片,虽然卫生巾并非一定要有两个襟片,但是两个襟片比一个襟片更好。还有虽然这二个襟片不一定非要彼此镜像对称的,但它们最好是这样的。因此,对一个襟片的说明也就是对另一个的说明,并且,为了清楚起见,对第二个襟片的讨论将予省略)。
襟片224是沿连接线226与中心吸收垫212相连。术语“连接线”用在这里指各种不同的曲线或者直线的任何一种。襟片224具有一个远离连接线226的外缘278,在图1所示的实施方案中,连接线226相对于外缘278是凹形的,这就是说,连接线226呈离开外缘278方式弯曲。在这个实施例方案中,连接线226和226′以及线缝239限定了一个中间部份比它的二头更窄的吸收装置(中心吸收垫212)使用者通常感觉中间部份比二端窄的卫生巾比具有均匀宽度的卫生巾更加舒适。
图2是图1的卫生巾210沿2-2剖面线的剖面图,总的说明卫生巾210的一个优先结构。如图2所示,中心吸收垫212包括一个吸收芯216中心吸收垫212和襟片224,两者都包括一个顶片214,底片218被放置在吸收芯216和襟片224的与顶片相反的侧面上。事实上,顶片214形成了襟片214的一个表面,而底片218形成了它的另一个表面;顶片214形成中心吸收垫212的一个表面,底片218形成其另一个表面。
在所示的实施例方案中,襟片吸收芯子230被插在顶片214和底片218之间。为了结构简单起见,襟片吸收芯子230覆盖整个卫生巾210并被放在吸收芯216和底片218之间。虽然这是一个主要为了结构上的原因而优先考虑的实施例,但是该襟片吸收芯230不一定必须被放在吸收芯216和底片218之间。
顶片214和底片218在围绕整个卫生巾210周边的接缝239上被连接在一起。这种接缝的目的是为使卫生巾的不同组成部份联合成一个整体、顶片214沿连接线226和226′用图2中未绘出的连接装置固定到襟片吸收芯子230和底片218上。
图2上所示了粘胶连接装置:分别由中心垫释放片222和襟片释放片238覆盖住的中心垫粘胶220和襟片粘胶236,这些粘胶接装置适合于把卫生巾210固定在内裤裤裆区内。
顶片214是可透过液体的、且在卫生巾210被使用时,是紧靠在使用者的皮肤上,顶片214是顺从的、感觉松软的和对使用者皮肤是无刺激的,它可以由通常适合于这类用途的任何一种材料制成。可以适合于用作为顶片材料的非限定性实例有编织和非编织的聚脂,聚丙烯尼龙和人造丝以及成型的热塑性薄膜,以成型薄膜最好、一些合适的成型薄膜被公开在1975年12月30日公布的Thompson的美国专利3,929,135,标题为“具有锥状毛细管的吸收结构”,1982年4月13日公布的Mullane和Smith的美国专利4,324,426,标题为“具有抗沾污顶片的一次性吸收物品”,1982年8月3日公布的Radel和Thompson的美国专利4,342,314,标题为“呈纤维状特性的弹性塑料网织物”,以及1984年7月31日公开的Ahr、Louis,Mullane和Quellete的美国专利4,463,045标题为“呈非光泽可见表面和布样感觉的宏观多孔的三维塑料网织物”,上述所有专利以引用方式被结合到本申请中。顶片214最好用成型薄膜,因为它们是透液体的但又是不吸收的。所以,与人体接触的成形薄膜的表面保持干燥,使使用者感到更舒适。
在本发明一些优选的实施例中,顶片214的外表面是用表面活化剂处理过的。用表面活化剂处理顶片的外表面使该表面更加亲水,其结果是液体渗透这种顶片比未处理过表面的要更快,这样消除了月经流出顶片214而没有为吸收芯216吸收的可能。表面活化剂最好大体上均匀和全部地分布在整个顶片214的外表面上,这可以由本专业技术领域内的熟练技术人员以一些公知技术来实现。例如,表面活化剂可以用喷射、浸染、或者使用传递滚筒施加到顶片214上。
在一些优先的实施例中,顶片214的内表面以接触关系被固定到吸收芯子216上,这种接触关系使得液体透过顶片214要比不与吸收芯216接触的情况更快。可以用施加粘结剂到顶片214的内表面上来保持顶片214与吸收芯216的接触,例如适用于此目的粘结剂包括由宾夕佛尼亚州,费城的Rohm    and    Haas公司制造的丙烯酸乳剂E-1833BT,明尼苏达州,圣保罗的H.B.Fullex公司制造的丙烯酸乳剂WB3805。这些粘结剂可以用将表面活化剂施加到顶片214外表面的相同方法施加。
参照附图2,可以看出吸收芯216被定位在顶片214和底片218之间,吸收芯216提供一个用于吸收月经流体的装置,吸收芯216一般是可压缩的、舒适的和对使用者的皮肤是无刺激的,它可以由该技术中用于该目的的任何一种材料组成,例如包括通常被称为含气毡(airfelt)的细木纸浆、绉纹的纤维素填料,吸收性泡沫塑料,吸收性海绵、吸收性水凝胶材料,聚合纤维,或者任何等效的材料,或者这些材料的组合。
底片218是不透液体的,由此防止了月经流体沾污使用者的衣服,在该技术中用于此目的的任何一种材料都可以使用于此。合适的材料包括模压的或非模压的聚乙烯膜和层压纸。合适的聚乙烯薄膜如由Monsnto化学公司制造的并以薄膜No8020在商业中销售的薄膜。
一般与吸收芯216对齐的底片218的外表面部份涂有中心衬垫粘结剂220,中心衬垫粘结剂220提供了一种把中心吸收衬垫212固定到内裤的裤挡部份上的粘连手段。在该技术中用于此目的的任何一种粘结剂或者胶都可用于此,最好使用压敏粘结剂。合适的粘结剂有Century    Adhesives公司制造的Century    A-305-lv,和National    Starch公司制造的lnstant    LOK    34-2823,如图2中所示,中心衬垫粘结剂220可以具有如吸心芯子216相同的宽度。然而,宽度不是要求很严格的,本专业技术领域内的熟练人员可以很容易地选取适当的宽度以及长度。中心衬垫粘结剂220的压敏粘结剂应该用中心衬垫释放护片222覆盖住,以避免粘结剂干燥和避免在使用前粘附到无关的表面上。任何市场上可买到的通常适用于该目的的释放护片都可用于此。适合的释放护片如Akrosil公司生产的BL30    MG-A    Silox    EI/0和BL30    MG-A    SILOX    4    P/0但不限于此。
如从上面的讨论中可以看到的那样,中心吸收垫212是一个吸收装置,它具有一个液体可透过的身体接触表面(图2中用顶片214表示)和一个在另一面的液体不能透过的表面(图2中用底片218表示)。应该理解所说明的实施例只是一个可能的实例,虽然是一个优选的实例,其它可能的实施例包括这样一个实施例,其中的吸收芯在放到底片上之前,基本上用顶片完全包起来。吸收装置也可以由单独就具有足够牢固性、并且其一个表面上是液体可透过的、另一个表面已经过处理,使它不能透过液体的吸收芯组成。
应该注意,一个窄的中心吸收垫212是有效的,因为该整体结构和卫生巾210的使用都使得中心吸收垫212被保持在最接近人体的部位上。中心吸收垫212这样的贴近,使它准确地位于它应该位于的地方:非常靠近人体的阴道开口处,因此,中心吸收垫212可以在月经流体有机会沿中心吸收垫212流动之前吸收绝大部份的月经流体。
可以看出,连接线226和226′是襟片224和224′沿此与吸收装置(用中心吸收衬垫212表示)相联结的线。就这样,它们表示吸收装置和襟片之间的界线。该连接线相对于外沿278和278′,和相对于中心吸收垫212的松散材料来说可以是凹形的、直线的或者是凸形的。
中心吸收垫212不会具有比预期吸收的月经总量大得多的吸收容量,因此,除了窄的外,中心吸收垫212可以是薄的。而且,一个薄的吸收物意味着对使用者是极其舒适的。在图1和图2显示的实施例中,顶片214起到襟片224和224′的顶片的作用。一般,襟片没有顶片也能使它们正常地工作,但使用顶片更好。襟片的顶片可以如图所示是和吸收装置的人体接触表面成一整体,或者它们可以是独立的组成部分,但前者更好、前面所讨论过的顶片214的所有具体的物理性质适用于任何被使用的襟片顶片。然而,并不要求襟片顶片与中心吸收垫的顶片是相同的材料。在一些优选的实施例中,该襟片的顶片可以是非编织材料,而在中心吸收垫上面的顶片是成型的薄膜。
在襟片224和224′中,最大量的是襟片吸收芯层230被定位于顶片214和底片218之间。在所示的实施例中,襟片吸收芯层230也在吸收芯216的下面;这是一种优选的安排方式,因为这种卫生巾210的结构由此而更容易制造。按这种安排,吸收芯216的吸收容量有所增加。襟片吸收芯层230提供了一个用于吸收未被吸收芯216吸收的、或者由吸收芯216压出的月经流体的手段。襟片吸收芯层230一般是可压缩的,舒适的和对使用者的皮肤没有刺激的,它可以用如前所述的可以用于制造吸收芯子216的任何一种材料做成。襟片吸收芯230最好是一种棉纸层。尽管高度推荐使用襟片吸收芯层,但也可以不用它。
在图1和图2所示的实施例中,底层218也起襟片224和224′底层的作用。这些襟片需要一个底层(或者更一般地,一种液体透不过的材料),使它们能正常地工作。襟片底层可以与吸收装置的液体透不过表面是一体的。或者它们可以是独立的组成部分;最好是前者。前述的底层218的所有具体的物理特征都适用于襟片的底层。
襟片214的总体尺寸可以由本专业领域的熟练人员很容易地选择的。卫生巾210最好在外缘278和278′之间最大间距为10-23厘米。襟片224最好在平行于卫生巾的纵轴方向上的长度是约5-18厘米。
接近外缘278的襟片224的外表面涂有襟片的粘合物236,襟片的粘合物236是用于在按下面要讲到的方式将它围绕着内裤裤裆部份的围包好之后协助襟片234保持到位的一种粘连手段,任何一种用于中心垫的粘结物220都可以用于襟片粘结物236。同样,襟片粘结物236也用一个可去掉的襟片释放护片238覆盖,任何一种用于中心衬垫的释放护片222的释放护片材料都可以用于襟片释放护片238。
如图1和图2所示,顶层214是沿接缝239固定到底片218上,接缝239可以用在该技术领域内用于该目的的任何一种方式形成,如粘结、卷边或热密封。接缝239被画出是整个地围绕卫生巾220的周边延伸的,这是为了结构简便的一个优选的实施例(也可以使用其它的方式将这些不同元件结合起来)。襟片吸收芯层230如图所示是延伸进入接缝339中的,同样,这只是一种出于简化构造方法的安排。
如图1和图2所示的卫生巾具有一个曲线的连接线226,如前所声明的,吸收芯子216一般成沙漏形(hourglass    shaped),以便一般地与穿戴者的腿裆一致。所以,襟片224和吸收芯216之间的连接线226是曲线,然而,可以容易地做成一般具有纵长向边的吸收芯子以及每个襟片和吸收芯子的纵长边之间的连接线是直线的卫生巾。以至使卫生巾宁可在每个襟片和中心吸收芯纵长边间的直线连接线处发生弯曲。
襟片224的准确形状,以及卫生巾的整个形状可以由本专业的熟练人员不必做过多的试验就能选定,在图1所示的优选实施例中,襟片沿卫生巾的纵轴对称配置,虽然这是一个优选的实施例,但它不是一个强制的结构特征。
另外,图1所示的卫生巾是一个襟片与卫生巾的顶片和底片是整体形成的实施例。同样,虽然这是一个优越的结构方法,但不是必须遵循的。襟片和中心吸收装置可以分别制成再用本技术领域的技术人员公知的技术连接起来,使得这样形成的卫生巾具有实质上等同于在此所示的实施例的功能。
图3是为众多妇女经常所穿着的,众所周知的内裤的裤裆部份224的一个示意图,内裤包括一个前面部份240,一个后面部份242,和连接这两部份的裤裆部份244,裤裆部份244又包括两个侧边246和246′,以及中间裤裆部份248。
本发明的卫生巾,如图1和图2所示的那样,是谌サ羰头呕て?22,238和238′后,如图4所示的把卫生巾放入内裤里使用。中心吸收垫212的中心放在内裤的裤裆岔部份244内,使其一端伸向内裤的前面部份240,另一端伸向内裤的后面部份242,且使底片218与内裤的中间裤裆部份248的内表面相接触。中心垫的粘结剂220使中心吸收垫212保持到位。襟片224和224′的远端部分分别围绕侧边246和246′折叠。襟片粘结剂236和236′使襟片224和224′固定在这样的位置上。因此,襟片224和224′它们每一个互相叠合使内裤的一部份包括侧边246和246′被置在它们之间。
虽然已经说明了本发明卫生巾优选的实施例,但可以得到其它为数众多的具有襟片的卫生巾实施例,且在文献中已经公开,时别是如下的专利中已经公开的那些具有襟片的卫生巾:在1987年8月18日公布的Van    Tilburg的表国专利4,687,478,标题为“具有襟片的成型的卫生巾”,1986年8月26日公布的Mattngly的美国专利4,608,047,标题为“卫生巾连接装置”,1986年5月20日公布的Van    Tilburg的美国专利4,589,876,标题为“卫生巾”,1981年8月25日公布的Mc    Nair的美国专利4,285,343,标题为“卫生巾”,1968年8月20日公布的Rickard的美国专利3,397,697,标题为“用于内裤的一次性卫生巾”,1957年4月2日公布的Clark的美国专利2,787,241,标题为“卫生巾”。所有上述这些专利通过引用被结合在本中清中。
已经说明了一种优选的卫生巾中,现将说明本发明的改进。如前所述,当襟片224沿在内裤的裤挡部份244的边246向下折摺时,在襟片224上产生应力,当襟片224在内裤下面被折叠并被连到内裤的下面时,应力被增大,当内裤向上拉到适当位置并在内裤边246上的弹性迫使襟片224进入穿戴者的开岔和腿挡的最上部时,应力更进一步的被增大,这些应力高度集中于沿襟片从处于内裤的人体侧变到内裤下侧的折叠处249,或者,换言之,是在内裤裤挡部份224内的边246上。于是,在襟片224内集中的应力一般沿着由内裤裤挡部份244的边所形成的弧存在的,如果应力大到足够程度,襟片224可能与内裤脱开,而襟片224将比最佳效果要差。取决于卫生巾的设计,集中应力的弧可以与襟片和吸收装置之间的连接线一致,但并非必须如此。
为了消除或者至少减少这些应力,卫生巾有一个第一应力消除装置250,该第一应力消除装置一定程度,减少沿折叠处249的应力,使得襟片224保持与内裤下例的连接。
再参照图1,一个优选的第一应力消除装置250是凹槽252,术语“凹槽”用在这里是指一个空间、缺口、或者沿材料或材料叠片的边沿的挖空。另一种推荐的第一应力消除装置250是在图5所示的本发明卫生巾210的另一个实施例所示的一个裂隙254。术语“裂隙”用在这里表示一个窄的切口,其中材料的二条边是彼此相邻的或者是接近相邻但彼此又不连接的。裂隙254可以是直线的,也可以是曲线的。
因为卫生巾210和襟片224有众多的可能的结构,因此在未看到具体被使用的卫生巾下,不可能讲明这种第二应力消除装置250应当在该具体设计的卫生巾的何处。然而,通过实验已经确定,第一应力消除装置250最好位于卫生巾250的一个边沿在使用时与内裤的边沿246相互交义的点上,襟片224和内裤的边沿246之间的交义点(通常与折叠线249的端部重合)就是为了减少在折叠处249的应力、第一应力消除装置250应该所在的位置。这样的第一应力消除装置可以是沿着襟片224和224′上的整个连接线249,或者是在连接线249的外侧。
交义点一般可以由一个模特儿穿戴具有襟片的特定设计的卫生巾和相当普通结构的内裤来确定。通常,内裤裤挡的宽度为约5.0至约7.5厘米。然后,可在卫生巾210的底表面上对卫生巾210与内裤交义的位置做一个标记。假定卫生巾有两个襟片,四个标记将标出第一应力消除装置250的一般位置,通常,第一应力消除装置250的位置在自卫生巾210的横向中心线300起的约2.5至约7.5厘米之间(纵向尺寸)。
为了说明下面的讨论,图5表示了具有襟片224和224′的一个推荐的卫生巾210,其中,襟片224有一对凹槽252,襟片有一对裂隙254。如图5所示,最好每个襟片224接224′有两个第一应力消除装置250,即在襟片的横向中心线300的每一侧有一个。且每个襟片224和224′上的每对第一应力消除装置250最好是对称的。
如图5所见,凹槽252和裂隙254每一个具有一个引导边262,引导边262本身是凹?52或裂隙254伸向吸收装置中心部份的一条边。在有两个边的凹槽的情况下,引导边262是最接近卫生巾210的最近末端255的边。如果凹槽252的边是呈V形缺口,或者裂隙254是曲线的或者是其它形状时,确定引导边262接近直线。
引导边262有一个角度265,它自与引导边262的原点2264相交并和卫生巾纵向中心线400平行的纵向线起测量。从纵向线起角度275推荐在约0°到约145°之间,0°-80°较好,最好为约0°-约40°。业已发现,角度在约20°-约40°范围内一般接近于由在襟片交义位置上内裤裤挡区域244内的边246的弧线所形成的角度,但是发现其它的推荐的角度也能减少应力。
引导边262的深度280是从如前所述的同一根纵向线起垂直测量的,优先的是在约2.0至约20.0毫米,较好的范围是约3.0至约12.0毫米,最好是约4.0-约9.0毫米。
如在图5所看到的,沿着襟片224和224′的远边278和278′有一个第二应力消除装置290,在襟片224远边278上的第二应力消除装置290是一个凹槽。在襟片224′远边278′的第二应力消除装置是裂隙形式的。这些第二应力消除装置290使得当襟片224和224′折向穿戴者的内裤下面时它们能够展开。由此减少了在襟片内可能产生的张力。第二应力消除装置最好是沿襟片的横向中心线300放置,这些第二应力消除装置最好从襟片的远边向里伸进3.0-30.0毫米。
图6是本发明的卫生巾200的另一个实施例,它具有另一个优选的凹槽形式的第一应力消除装置250。
虽然已经说明和画出了本发明的一些具体的实施例,应该明白,本专业的熟练技术人员显然可以在不离开本发明的构思和范围下做出各种不同的其他改变或改进。
