Problems solved by technology

Lacking effective wicking properties, menstrual fluid will be concentrated in certain areas of the napkin, thus not effectively utilizing the full absorbent capacity of the napkin
On the other hand, sanitary napkins, whose wicking properties are especially effective, have other problems
Specifically, these sanitary napkins may wick liquid to the longitudinal sides of the absorbent structure, causing liquid to leak through the longitudinal sides of the sanitary napkin, i.e. side leakage

Embodiment

[0093] Embodiment of the invention

[0094] The structure of the sanitary napkin according to the embodiment of the present invention is as follows.

[0095] The overlay was removed from the Stayfree Dry Max Ultrathin product sold by McNeil-PPC, Inc., spread flat on a conveyor belt, and coated with 1.3 gsm from Bostik Corporation, Wauwatosa, Wisconsin, USA. WI) A hot melt adhesive sold under the trade designation NW1023ZP was slot die coated. The 100 gsm primary absorbent layer was comprised of an air bonded wood pulp material sold under the tradename VIZORB 3045 by Buckeye Technologies, Memphis, Tenn. Die the first absorbent layer into 5 longitudinally extending material-free regions, such as figure 1 shown. Each material-free zone has a length of 150 mm and a width of 5 mm, and each material-free zone is laterally spaced 10 mm from an adjacent material-free zone. The thickness of the first absorbent layer is 2 mm. The second absorbent layer is manufactured by EAM Cor...

Abstract

The present invention generally relates to absorbent sanitary napkins and in particular to a sanitary napkin including an absorbent layer having a plurality of spaced beam elements for promoting enhanced fluid wicking within the sanitary napkin.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from application 60 / 983,780, filed October 30, 2007, which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates generally to absorbent sanitary napkins and, in particular, to sanitary napkins comprising an absorbent layer having a plurality of spaced apart strip elements to enhance liquid wicking within the sanitary napkin. Background technique [0004] In order to provide a sanitary napkin that can effectively absorb large quantities of liquid during use, the absorbent structure throughout the sanitary napkin must be capable of effectively wicking liquid. Without effective wicking properties, menstrual fluid will be concentrated in certain areas of the sanitary napkin, thereby not effectively utilizing the entire absorbent capacity of the sanitary napkin. On the other hand, sanitary napkins, whose wicking properties are particula...
