Abstract

在体液吸收物品的透液性表层上为了将体液的流动控制在某个预定方向上，本申请揭示了一种热塑性合成树脂制成的改进的透液性表层，它包括多条第一方向肋条和多条第二方向肋条，第一方向肋条与第二方向肋条相交从而形成一独特的肋条结构。第二方向肋条3的顶部7与各第一方向肋条2的相对的侧壁6连接，每对相邻第一方向肋条2限定一条槽10，用于引导体液沿某个预定方向流动。

Description

z
条限定一个透过液体的孔。在这些第一和第二方向肋条的各个交叉点处，第二方向肋条的顶部与第一方向肋条的侧壁相接，从而形成交叉的肋条结构，这是本实用新型最重要的特征。
在具有这种肋条结构的表层中，多条第一方向肋条沿第一方向平行伸展，每条相邻的第一方向肋条与第二方向肋条保持相互间隔一给定距离。第二方向肋条的顶部连接第一方向助条的侧壁，因而，每对相邻的第一方向肋条限定一条沿第一方向伸展的槽，其底部有第二方向肋条和孔。这种槽使体液沿第一方向流动比沿垂直的第二方向流动要容易。
下面将参照附图对本实用新型作更详细的说明，其中：
图1是根据本实用新型而构造出的表层的透视图；
图2是沿图1中X—X线的剖视图；
图3与图1类似，但显示本实用新型的另一实施例；
图4与图1类似，但显示本实用新型的又一实施例；
图5是卫生餐巾的透视图。
图1是透视图，显示出根据本实用新型而构造出的表层l的表面结构。表层1包括多条第一方向肋条2和多条与第一肋条2交叉的第二肋条3，其中，每对相邻的第一方向肋条2与每对相邻的第二方向肋条3限定一个透过液体的孔4。每条第一方向肋条2具有沿第一方向伸展的顶部5，和从顶部5向下弯曲至各个下沿6A的相对的侧壁6。每条第二方向肋条3是扁平的，类似于薄片，它沿第二方向伸展，有一限定其上表面的顶部7。在第一方向肋条2与第二方向肋条3的各个交叉点处，第二方向肋条3在下沿6A或下沿的邻近处与第一方向肋条2的侧壁6连接，这样，每对相邻的第一方向肋条2被保持成相互间隔一预定的距离，从而形成沿第一方向伸展的槽1O。槽10在其底部有第二方向肋条3和透液的孔4。
图2是沿1中X—X线的剖视图，显示各第一方向肋条2的下沿6A如何与各第二方向肋条3的顶部7连接以及槽10如何由每对相邻的第一方向肋条2所形成。
图3是与图1类似的透视图，但示出本实用新型另一实施例。其中，各第二方向肋条3的顶部7与一对相邻的第一方向肋条2中的一条在靠近下沿6A处连接，而与另一条在侧壁6的上部连接。在这种结构中，也形成了槽10。
图4是类似于图1的透视图，但示出本实用新型的又一实施例，其中，第二方向肋条3在宽度和高度上都小于第一方向肋条2，但具有顶部7，和相对侧壁8，该侧壁与第一方向肋条2的侧壁是类似的。顶部7与第一方向肋条2的相对的侧壁6连接。第二方向肋条3的顶部7不凸出于第一方向肋条2的顶部5，每对相邻的第一方向肋条2限定一条沿第一方向伸展的槽10。
表层1的各个构成部分最好具有这样的尺寸，即，槽10在每对相邻的第一方向肋条2的下沿6A之间具有0.1至3mm的宽度，第一和第二方向肋条2、3具有0.3至3mm的宽度，第一方向肋条2具有0.2至3mm的高度，第二方向肋条3具有比第一方向肋条2小的高度，孔4具有0.1至9mm2的面积。第一方向肋条2有0.02至0.2mm的厚度，第二方向肋条3的厚度等于或小于第一方向肋条2的厚度。该表层1可以通过对聚乙烯薄片之类的热塑性薄片热成形而获得。如果表层1是疏水的，则其表面必须用亲水的媒剂作适当的处理，以控制其对体液的湿润性，从而使体液在各条槽10的侧壁与体液之间的毛细管作用下沿第一方向迅速地扩展。
图5是卫生餐巾20的透视图，该卫生餐巾利用了本实用新型的表层1。卫生餐巾20剪裁成长方形，纵向与槽10的走向一致。使用卫生餐巾时，各第一方向肋条2的顶部5与使用者的皮肤接触。因而，在表层1上的体液迅速地沿各条槽10流走，扩散至其纵向上的相对两端。相应地，体液在卫生餐巾横向上的流动得到抑制，有效地避免了体液从卫生餐巾20的两侧漏出。
本实用新型的表层利用某个预定方向的槽，使体液的流动得到控制，同时，防止了体液从槽的旁侧漏出。
