초록 ▼

The invention relates to absorbent products (1) like baby diapers, adult incontinence products and particularly to sanitary napkins or pantyliners. These absorbent products all have absorbent cores (4) which according to the present invention comprise absorbent gelling materials (5) in granular form or other particles. A problem associated with such cores is that these particles can migrate out of the article along the paths of liquid entry into the product. Therefore, a shield (8) positively separating the paths of liquid transport into the product from the particles is provided for absorbent structures according to the invention.

대표청구항 ▼

[ What is claimed is:] [1.] An absorbent product comprising a topsheet having liquid passage ways, a liquid impervious backsheet, and an absorbent core interposed between said topsheet and said backsheet; said core comprising dry particles, said particles being capable of permeating in their dry state through said topsheet along said liquid passage ways; said topsheet having a central region which comprises said liquid passage ways and an external region which is impermeable to said particles; said absorbent product further comprising a permeation blockage means to restrict permeation of said particles to said liquid passage ways; said permeation blockage means being between said core and said topsheet; said permeation blockage means being joined to either or both of said topsheet and said backsheet of said absorbent product in order to shield either said particles from said liquid passage ways or said liquid passage ways from said particles; said permeation blockage means extending beyond the periphery of said central region.
