Abstract
本发明公开的是一种具有横向分段的吸收芯的卫生巾。它被分成几个独立的段,每一段能在Z方向运动,而不受由相邻段施加的对这种运动的限制,每一段可以与相邻段不连接,或者用与卫生巾纵向中心线对齐的细颈形连接件连接,或者用两个细颈形连接件连接,其每一个与芯的每一个纵向侧边边界对齐。
Description
本发明涉及卫生巾,更特殊地,涉及具有更适合穿戴者身体的分段芯的卫生巾。
本发明涉及卫生巾,尤其涉及卫生巾的芯,它被横向地分成许多独立地动作段。按照已有技术的卫生巾,每一段都不受由芯的其它部份施加的对运动的束缚。没有束缚和均匀的降低束缚使每个芯段能更精确地,更可靠地和更舒适地适应穿戴者的身体。
在已有技术中,为了提供了合适地和有效地与穿戴者身体适应的卫生巾,已经做了许多尝试。例如,1976年5月4日公开的Chesky等的美国专利US-3,954,107公开了一种纵向活节式的卫生巾,这种卫生巾特征是有一对并排配置的吸收垫。虽然这种结构能够提供卫生巾与穿戴者的左半身体和右半身体有良好的适应性,但它不能提供,也没有适应在穿戴者身体形状上的从前到后的差异。
1986年5月20日公开的Van Tilburg的美国专利4,589,876公开了一种具有从中间的吸收垫的每一纵向边向外延伸的瓣状物的卫生巾。每个瓣状物最好在瓣状物和中心吸收垫的纵向边之间的连接线上弯曲。然而,该连接线也是纵向方向的,并没有提供使卫生巾适合于穿戴者身体形状的从前到后差异的装置。
1988年9月27日公开的Molee等的美国专利US-4,773,905公开了一种具有由芯的受压缩区域形成的两个横向铰链的带翼状物的卫生巾,这种结构据称能使卫生巾很容易地围绕铰链弯曲,然而,由于卫生巾是用铰链连接的,而铰链桥接卫生巾芯的不同部份,如果没有有效的压力,芯的不同部份之间的有效的和无阻碍的Z方向的不连接性是不能实现的。
其它许多专利给出稍微适合于穿戴者外阴的抬高中心部份的教导。例如,1956年5月29日公开的Mevcer的美国专利US-2747575公开了一种具有横向收缩体的月经带,所说的横向收缩体形成一个永久保持的隆起,月经带有一个隆起的保持装置,如平行的缝线,由此,隆起保持它的形状,并固有地适合身体的形状,且是舒适的。1986年12月23日公开的Lassen等的美国专利4,631,062和1987年6月16日公开的Lassen等的美国专利4,673,403都公开了向上凸出形状的卫生巾,所说的卫生巾具有一个用于配置在穿戴者前庭范围内的抬高的轮廓。
1988年7月19日公开的Glassman的美国专利US-4,758,240公开了一种具有多个纵向通道和与卫生巾的纵向中心线一致的抬高的中心屋脊状的卫生巾。然而,所有这些教导的一个缺点是卫生巾的抬高部份都是通过它的整个纵向长度,而没有注意到这些抬高部份在哪里是最有利的或者必需的,且这些抬高部份对于穿戴者身体的阴阜区域可能是不需要的。
本发明的目的在于提供一种适应穿戴者身体形状上的前后差异的卫生巾,它能更精确地和更舒适地在整个卫生巾长度范围内与穿戴者的身体适应。本发明再一个目的在于提供一种卫生巾,这种卫生巾在Z方向不连接,在芯的邻近部件中没有值得注意的应力。本发明的再一个目的是只在卫生巾部份区域内提供抬高的中心段,在此这个部份为使用者提供好处。
本发明包括一个具有纵向中心线,两个纵向侧边边界和两个横向侧边边界的卫生巾。卫生巾具有一个液体可透过的顶层,和一个至少部份在边缘上连接到顶层上的液体不能透过的底层,在顶层和底层之间是一个横向上分成许多段的吸收芯,每一段用两个纵向侧边为界。
横向分段的芯的独立段可以与相邻段不连接,这取决于所选择的实施例。另一方面,卫生巾可以包括一个连接相邻独立段的细颈形连接件。取决于所选的实施例,可以有一个基本上与卫生巾纵向中心线对齐的细颈形连接件,或者,可以选择地具有两个细颈形连接件,每一个基本上与吸收芯的纵向侧边对齐。
当说明书以特别指出地和清楚地要求保护本发明的权利要求书为结尾时,可以相信,从下面结合附图所作的说明将更好地理解本发明,其中相同的部份将用相同的标号,类似的部份用“ ’”表示。
图1是按照本发明的卫生巾的平面图,它具有一个以部份剖面图展示的顶层,并具三个独立的,不连接的横向分段的芯段;
图2是按照本发明的卫生巾芯的平面图,它具有三个独立段,每段用两个细颈形连接件连接到相邻的段上,每个细颈形连接件,基本上与吸收芯的纵向侧边对准;
图3是按照本发明的卫生巾芯的平面图,它具有两个由与卫生巾纵向中心线对齐的细颈形连接件连接的独立段;
图4是按照本发明的混合式的卫生巾的平面图,它具有三个独立段,两个是用与芯的纵向边对齐的细颈形连接件连接,两个用与卫生巾的纵向中心线对齐的细颈形连接件连接。
图5是放大了的沿图1的5-5剖面线的局部垂直剖面图,表示图1所示卫生巾的芯的相互相对的共同倾斜的横向边。
参照图1,在一个实施例中,本发明包括一个卫生巾20,它用于收集阴道排出物,例如月经,和防止由这些排出物弄脏穿戴者的被褥和衣服。卫生巾20特征是有一个液体可透过的顶层22,一个液体不能透过的底层24,一个在顶层22和底层24之间的吸收芯26。卫生巾20的周边由两个纵向侧边边界30和两个横向侧边边界32确定。
卫生巾20和吸收芯26具有一个纵向中心线34,该中心线在概念上把卫生巾20分成两个实际上对称的相对的一半。在此使用的术语“纵向”是指卫生巾20和吸收芯26的一个假想线,轴或者方向,该假想的线、轴或方向通常在吸收芯26的纵向侧边边界之间的中间,且对准把站立的穿戴者平分成左边身体一半和右边身体一半的垂直面。术语“横向”是指一条假想线、轴或方向,它们通常与纵向方向正交,且在吸收芯26的卫生巾20的平面内,且通常相对于穿戴者的横向取向。
继续参考图1更详细的分析本发明的部件,顶层22是一个穿戴的部件,它对着并接触穿戴者身体,并接收人体排出物。顶层22是液体能透过的,且应该是柔软的,对皮肤无刺激,在此使用的术语“柔软的”是指依从和并易于与身体形状一致或者在存在外力的情况下靠易于变形而适应的材料。优选的顶片不存在噪音,对穿戴者提供便利,顶片22应该卫生、外表清洁并稍有些不透明,以便隐匿在其上收集的并由芯26吸收的人体排出物。
顶层22还应呈现良好的透过和再湿特性,使得人体排出物能很快地渗透过顶层22到芯26内,但不通过顶层22回流对穿戴者的皮肤上。适当的顶片22可以用无纺材料或者多孔聚烯烃薄膜制造。
顶层22可以有许多孔,使落在其上的液体进入芯26。一种具有5-60%的多孔面积,典型的是25%,穿孔前的厚度为0.01-0.05毫米,穿孔后为0.42-0.51毫米的穿孔聚烯烃薄膜顶层22是合适的。
如果需要,顶层22可以用表面活化剂喷涂,以促进液体渗入芯26。表面活化剂一般是非离子式的,对皮肤无刺激的。顶层22上的每平方厘米0.01毫克的表面活化剂的密度是合适的。适用的表面活化剂可由Conneeticut州的Greenwicb的Glyco化学公司供应,商标为Pegosperse 200ML。
特别合适的顶层22可以按1982年8月3日公开的Radel等的美国专利US-4,342,314和1984年7月31日公开的Ahv。等的美国专利US-4,463,045制造,上述专利为了公开特别优选的液体可透过的顶层实施例的目的在此作为参考文献引入。顶层22可以用由印第安纳州的Terre Haute的Tredeger公司销售的X-3265型和P1552型穿孔成形的薄膜制造,已经发现其工作情况良好。
底层24可以是任何柔软的、阻挡液体的,最好是液体不能透过的材料,如聚烯烃薄膜。底层24防止由卫生巾20收集,并由它贮存的排出物,特别是由芯26吸收的排出物从卫生巾20泄漏,而污染穿戴者的衣服和被褥。优选底片24是无噪音的,为穿戴者提供方便。
底层24应该不透过由所吸收的人体排出物产生的臭气,因此,臭气不能泄漏并使穿戴者注意到。厚度为0.01-0.08毫米,优选的为0.05毫米的低密度聚乙烯薄膜底层24已发现具有良好的工作性能。聚乙烯薄膜,如由印第安纳州的Terre Haute的Tredegar公司提供的X-813型聚乙烯业已发现特别适用于底层24。
可以选择地,底层24也可以用柔软的类似于衣服的材料制造,它相对于顶层22更具疏水性,例如:聚脂或聚烯烃纤维底层24都有良好的工作的性能。特别优选的柔软的类似于衣料的底层24材料是一种聚脂无纺材料层和一种薄膜的叠层材料,其中薄膜如1984年10月9日公开的授予wnuk的美国专利US-4,476,180所描述的。
在一个实施例中,底层24稍比顶层22和中间的吸收芯26大一些。在该实施例中,底层24沿四周外接顶层22和中间吸收芯26,该底层有一个从顶层22的侧边向外延展的大约0.5-1.5厘米的径向余边,优选大约1.0厘米。这种几何结构使得如果芯26超载将提供一个保护的边界区域,否则卫生巾20将失败。在这样实施例中,底层24和瓣状物优选是一体的并且是共同延伸的。
底层24朝外的表面进一步包括用于把卫生巾20连接到穿戴者内裤上的装置。为了这个目的,业已发现压敏粘结物质具有良好的工作状况。优选的纵向粘结条为阻止卫生巾的前面或后面从穿戴者的内裤上分离提供了良好的保护,粘结条可以是连续的或者是间断的,特别优选的配置是使用两个纵向方向上的粘结条,即在纵向中心线34的每边上一个。
顶层22和底层24优选地是用已知技术沿周边连接,要么是整体地,以使得卫生巾20的整个周边是用这种连接外接,或者是在周边的部份周边上连接。术语“连接”是指一种状态,在该状态中,第一部件或部份要么直接地固定到第二部件或部份上;或者,第一部件或部份间接地固定到一个中间件或中间部份上,依次它又被固定到第二部件或部份上。第一部件或部份和第二部件或部份之间的连接性是用来保持卫生巾20的寿命。
芯26最好是夹在顶层22和底层24之间,以防止在佩戴卫生巾时芯26的吸收材料扯破或者分离,并保证适当贮存人体排出物。这种结构也有助于提供一体的卫生巾装置。
为收留在顶层22和底层24之间的芯的任何连结装置和一体装置都是合适的。这样一种装置具有两个互相面对的主表面,一个由顶层22确定,另一个由底层24确定。
吸收芯26是一个用于收集和贮存人体排出物,特别是月经的装置,这些排出物是沉积在芯上的或者是通过液体可透过的顶层22渗入的。芯26是卫生巾20接受和保存人体排出物的装置,芯26是适合皮肤的,且对皮肤无刺激。
芯26可以具有矩形的周边或者水漏形的周边。吸收芯26的周边是由两个纵向侧边30′和两个横向侧边32′限定,它们分别与卫生巾20的纵向侧边边界30和横向侧边边界32对齐,芯26最好具有两个相对的主表面,一个面向底层24,一个面向顶层22,且通常是平面的,亦即没有厚度上明显的变化或者分离的肉眼可见的起伏。
适合于芯26的材料包括空气毡,如纤维素填料,和纤维化的共有纸浆的混合物;叠层的组织纸;和吸收凝胶材料。如果选择组织芯26,它可以按照1980年3月4日公开的Trokhan的美国专利US-4,191,609制造,在此以参考文献引入,以表明对于在此所描述的卫生巾20的特别优选的组织纸的结构。如果要求在卫生中20的芯26内含有吸收凝胶材料,按1988年4月19日公开的Brandt等的美国专利Re-32,649制造的吸收凝胶材料是合适的,在此作为参考文献引入该专利,以展示特别优选的吸收凝胶材料。一种合适的吸收凝胶材料和组织纸的叠层制品可以从Lowa州的Muscctine的Grrain Processing公司买到,型号是LS35。
芯26并不需要具有比要吸收的人体排出物总量大得多的总吸收容量。芯最好是窄而薄的,以便使穿戴者舒适。对于在此所描述的实施例,吸收芯26的容量至少应该是2克9%的盐溶液,适合的盐溶液是由Illionis州的Deerfield的Trawenol实验室售出。
芯26应该具有与顶层22和底层24相对齐的大小。为了便于制造,吸收芯26应该是矩形的,吸收芯26可以具有弧形的边界30′和32′,接近于横向中心线时逐渐向内缩成优选的外形。吸收芯26可以稍为有一点水漏型,以制造困难为代价而提供一不通常的优选的外形。
按照本发明的卫生巾20最好具有小于4毫米,特别优选的是小于6毫米(0.24时)的厚度,测量是用一个具有80.0克试验重量的比较仪,和一个具有直径为2.54厘米的10.0克的比较器脚,其接触表面积为5.1平方厘米。另外,本发明的卫生巾20顶层22的表面积至少为100平方厘米,以防止排出的体液对不准目标区域。
芯26可与底层24连接。芯26连接到底层24优选地是用粘接剂把芯26连接到底层26上来完成。这些粘结剂(未绘出)可以以任何合适的喷涂图形施加,如螺旋形的,或者纵向波纹。粘结剂应该是防表面活化的,且是低压敏的,以此而不粘到穿戴者皮肤上。
卫生巾20也可以包括瓣状物(未绘出),它是从卫生巾20的纵向侧边边界30向外延伸,优选地从卫生巾20的每一个纵向边界30向外延伸一个瓣状物具有一个近端36,典型地是与瓣状物装到卫生巾20的纵向边界30上的连接物重合,或者,另一方面,瓣状物的近端36可以在与纵向边界30斜接的任何位置上连接到卫生巾20上。瓣状物从卫生巾20横向向外延伸并终结于远点38,该点表示瓣状物最远离卫生巾20的纵轴34的点。
瓣状物可以包括顶层22,底层24或二者叠层制品的整体的并且连接的延伸。另一方面,瓣状物可以由连接到卫生巾20的纵向边界30的分离和独立的材料件制成。瓣状物优选地是按1986年5月20日公开的Van Tibung的美国专利US-4,589,876和1987年8月18日公开的Van Tibung的美国专利US-4,687,478制造。
芯26分成多个独立的段26′。尤其段26′是横向地独立分段。在此使用,段26′被认为是“独立的”意指段26′可以在Z方向上相对运动,而没有受相邻段26 ′对这种运动的限制。具有折叠线和划痕的芯26被认为不具有“独立的”段26′,因为对Z方向运动的限制在横过折叠线或者划痕线时发生,尽管这样折叠线或划痕线可以起类似于铰链的作用,使芯26在特殊的连接点可以弯曲。芯26被认为可以横向地分段,当相邻段26′之间的分界具有在芯26平面内的矢量分量,且总是正交于纵向轴34时。在此使用“Z-方向”是指通常是正交于芯26或者卫生巾20的平面的方向。
芯26可以分成多个段26′,优选地是分成三个独立的段26′。三段芯26是所希望的,因为当沿着纵向轴观察穿戴者时,穿戴者被分成三个解剖学上形状区分清楚的区域。从穿戴者的前面到后面,三个区域中的第一个是具有复合曲线型的向上凸出的阴阜区域。第二个区域是由大阴唇限定的,并且有类似于w型轮廓。第三个区域是由股沟确定,通常呈瓣尖形状,它由两个向上凸出并向外分叉的线确定。显然,需要卫生巾20适合于穿戴者身体的这三个形状区分非常明显的区域。
按照本发明的卫生巾20可以包括三个不连接段26′的芯26,芯26的段26′如果是不直接连接到相邻的段26′上,可以认为是“不连接的”。然而,不直接连接的段26′可以认为是独立的,如通过顶层22,底层24或任何组织物缠到的芯26。
如果卫生巾20具有三个段26′,它们在纵向长度上并不需要相等。例如,一个具有三段26′的卫生巾20,后面段26′在纵向上为7.0厘米(2.75吋),中间段26′为7.0厘米(2.75厘米),前面段26′为6.4厘米(2.5吋),业已发现性能良好。
在段与段之间在纵向尺寸上的差异可以解释成贴合穿戴者身体的大阴唇区域的中心段26′获得良好贴合的是最关键的,第二关键需要获得良好贴合的区域是发生在卫生巾20的后面部份,以适应股沟,而卫生巾20的前部贴合到穿戴者身体的阴阜区域是最不关键的。
参照图2,按照本发明的卫生巾20的芯26可以具有独立的但连接的段26′,段26′可以通过一个细颈形连接件27连接,细颈形连接件27最好包括不超过20%,优选地不超过10%的卫生巾20的芯26的宽度。如图2所示,细颈形连接件27可以沿卫生巾20的芯26的纵向边30′配置。这样一种结构提供了在卫生巾20的芯26的相邻段26′之间最大的相对的Z一方向位移,以便产生通常与卫生巾20的纵向中心线34相一致的位移。因此,这种结构是特别适合于获得卫生巾20的芯26与穿戴者阴道开口良好的适应性。
参考图3,如果需要,按照本发明的卫生巾20的芯26包括多个两个独立的段26′。如果选取这种结构,这些段26′之间的间隙应该确定,因而使得卫生巾20的芯26的后面段26′应为卫生巾20的芯26的纵向总长度的20-60%。芯26的前面段26′可以比后面段26′更长,以便适应穿戴者身体的前面区域和中心区域的向上凸出的结构,(如前所述的那样)。
如由图3所示的,细颈形连接件27基本上是与卫生巾20的纵向中心线对齐。这种结构提供的优点是:卫生巾20的芯26的纵向边30′是自由的,且卫生巾20的芯26的相邻段26′之间的最大Z一方向相对位移可以发生在这个纵向边30′上。然而,尽管这种结构可以对穿戴者提供更加舒适的贴合,对大腿内侧有较小的磨擦,但不能获得与阴道开口最大的贴合。
参考图4,引入图2和图3中的细颈形连接件可制成混合型卫生巾20。这样的卫生巾20具有一个对齐纵向中心线的,并连接卫生巾20的芯26的前面段26′和中心段26′的细颈形连接件27。这种细颈形连接件27使与较平缓的向上凸出的阴阜区域的形状一致的芯26的段26′具有比与较轮廓明显的,具有较小弯曲半径的穿戴者身体的大阴唇区域更凹进的形状一致的芯26的段26′有更大的弯曲半径。这对本领域的熟练技术人员是显而易见的,当特殊段26′的曲率半径增大,该段26′的纵向侧边30′之间和卫生巾20的纵向侧边30′之间的间距也增大。
然而,连接卫生巾20,后段和中间段26′的细颈形连接件27基本上与卫生巾20的芯26的纵向边对齐,这种结构允许在卫生巾20的纵向中心线34上产生后面段的Z方向最大位移,因此,后面段26′可以精确地且舒适地适合穿戴者的股沟。
如果需要,芯26的后面段26′可以有一个纵向上的切缝(未绘出),以便进一步增加后面部份与穿戴者的适合程度。如果切缝在卫生巾20的芯26的后面段26′上,切缝不应该穿通底片,否则就可能出现体液泄漏在穿戴者的衣服和被褥上。
在卫生巾20的芯26的后面段26′内的切缝并不需要平行于纵向轴。而是切缝可以在纵向轴的±45°范围内,或者类似于一个具有与卫生巾20的芯26的后面段26′和邻近段26′之间边界对齐的顶点的V形。
参考图5,如果需要,卫生巾20可以有一个促进卫生巾20的芯26的相邻段26′之间纵向运动的装置。典型地,后面段26′和中心段26′之间的纵向运动是由于受穿戴者身体运动,如坐下或躺下传给卫生巾20和它的芯26的力而发生的。
一种用于助长芯的相邻段26′间的纵向运动的装置为段26′提供了相互共同倾斜边33。段26′的横向边应该相互共同倾斜,特别是如果芯26相对较厚的话。更特殊地,纵向运动可以更加容易地靠提供具有后面段26′和相邻段26′之间的相互共同倾斜的边33来促进,因此,后面段26可以叠加在相邻段26′上。当后面段26叠加并且是在相邻段的上面,后面段26是夹在相邻段26′和顶层22之间。如果每个边具有一个相对于Z一方向的斜断面平面,该平面接近于互相平行于面向芯26的段26′边的斜断面地相对平面,则芯26的段26′的边被认为“相互共倾斜”。
如果提供相互共同倾斜边33,特别需要段26′是不连接的,这样纵向运动不受细颈形连接件27阻碍,相反,它允许Z一方向运动。
本专业技术领域的普通技术人员应该明白,本专业的普通技术人员可以做出上述实施例的其它组合或变换,但所有的这一切都在所附权利要求书的保护范围之内。
例如,邻近段26′之间的边界不必是如图所示那样直。此外,相邻段26′间的边界可以是弧状的或者包括多个直线线段26′,这些段相对于卫生巾20的纵向轴是斜纹的。
