Problems solved by technology

But this operation has the disadvantage of negatively affecting the absorbent capacity of the sanitary napkin
The compacting action greatly reduces the void volume in the absorbent layer of the sanitary napkin, thereby reducing its ability to store liquids

Embodiment Construction

[0010] refer to figure 1 , which shows an embodiment of the present invention, a feminine sanitary napkin 20. The sanitary napkin 20 has a main body 22 having a first transverse end 26 and an opposite second transverse end 28 the distance between which defines the length dimension of the sanitary napkin. The main body 22 also has two longitudinal sides, a longitudinal side 30 and an opposite longitudinal side 32, the distance between which defines the width dimension of the sanitary napkin. The main body 22 has a central longitudinal axis 34 which is an imaginary line dividing the sanitary napkin 20 into two substantially equal halves. The main body 22 also has an imaginary transverse centerline 36 which is perpendicular to the central longitudinal axis 34 .

[0011] try figure 2 ,it is figure 1 A cross-sectional view of a sanitary napkin, the main body 22 is a laminate structure that preferably includes a liquid-permeable cover layer 42, an absorbent core 44, and a liqui...

Abstract

A sanitary napkin for placement in a crotch portion of an undergarment of a wearer having a longitudinal axis and being further characterized by having a preferential bending zone extending obliquely in relation to the longitudinal axis, each preferential bending zone being located solely in an end region and does not extend into a central region of the napkin. The preferential bending zone may be created by mechanically embossing the surface of the sanitary napkin to locally density the absorbing materials of the article. The preferential bending zone causes the end regions of the sanitary napkin to resist lateral compression forces exerted by the thighs of the wearer and thereby prevents bunching of the article on the undergarment. The central region 70 of the sanitary napkin conforms to the wearer's body providing greater comfort for the wearer of the napkin.

Description

technical field [0001] The present invention relates to sanitary napkins which are thin, absorbent, and have a softness selected to provide good comfort while reducing the likelihood of involuntary deformation during use. Background technique [0002] In recent years, the hygiene protection industry has developed improved sanitary napkins that are both highly absorbent and thin with significantly increased comfort. According to conventional concepts, the comfort of a sanitary napkin is directly related to its softness, especially in the lateral direction. Therefore, in order to improve comfort, sanitary napkin designers have generally sought to create products that are as soft as possible. The argument in favor of this solution is that soft products cause less discomfort to the user when the sanitary napkin is compressed between the wearer's thighs. [0003] However, highly flexible sanitary napkins are known to suffer from a high failure rate attributable to the inability...
