Embodiment Construction

[0024] Description of the preferred embodiment

[0025] The following description of the invention will be based on its preferred embodiments.

[0026] figure 1 shows a plan view of a sanitary napkin according to a first embodiment of the present invention viewed from its top surface. Figure 2(a) and Figure 2(b) schematically show the figure 1 The cross-section of the anti-leakage barrier on the different parts of the sanitary napkin, image 3 means figure 1 Perspective view of a sanitary napkin.

[0027] Such as Figure 1-3 As shown, the sanitary napkin 1 of this embodiment comprises a liquid-retaining absorbent layer E and a liquid-impermeable barrier layer F. The absorbent layer E comprises a liquid-permeable top layer 2 and a liquid-retaining absorbent core layer 4, while the containment layer F comprises a liquid-impermeable bottom layer 3. An absorbent core layer 4 is interposed between the top sheet 2 and the back sheet 3 .

Abstract

An absorbent article 1 comprising a liquid retentive absorbent layer and a liquid impermeable leak preventive layer and including, in its longitudinal direction, an excretion portion facing section A which is placed opposite a wearer's liquid excretion portion, when in wear, and a rear section B which is placed more on the back side than the excretion portion facing section A, when in wear, wherein a leak preventive wall 5 is disposed on opposite side portions in the longitudinal direction, the leak preventive wall 5 comprising a basal wall portion and a planar elastic expansible / contractible portion connected to an upper end portion of the basal wall portion and being raised in the excretion portion facing section A and in the rear section B, and wherein a distance from an upper end portion of the basal wall portion to the leak preventive layer in the rear section is shorter than a comparable distance in the excretion portion facing section A.

Description

technical field [0001] The present invention relates to an absorbent article, such as a sanitary napkin, an incontinence pad, etc., and more particularly, to an absorbent article having excellent comfort and liquid leakage resistance, and its excellent performance is almost do not fall. Background technique [0002] Heretofore known as absorbent articles such as sanitary napkins, incontinence pads, etc., which provide an elastically stretchable / shrinkable portion at the leak-proof barrier which can be pulled longitudinally stretches and contracts, and comes in flat contact with the wearer's skin. [0003] The purpose of providing such an anti-leakage barrier is to form the absorbent article into a three-dimensional shape (in particular, partially concave in the longitudinal direction) to provide comfort to the wearer and to improve adhesion to the wearer's skin, Leakage of liquid is thereby reliably prevented. [0004] However, conventional absorbe...
