LIQUID-ABSORBENT STRUCTURE FOR WEARING ARTICLE
First Claim
1. A liquid-absorbent structure for a wearing article having a longitudinal direction and a transverse direction, the liquid-absorbent structure comprising;
- a first sheet;
a second sheet opposed to said first sheet; and
a liquid-absorbent core material sandwiched between said first and second sheets, whereinat least one of said first and second sheets is liquid-pervious;
said first sheet has a first inner surface facing said liquid-absorbent core material and a first outer surface opposed to said first inner surface and said second sheet has a second inner surface facing said liquid-absorbent core material and a second outer surface opposed to said second inner surface;
said first inner surface and said second inner surface respectively comprise first and second bonding regions respectively formed with bonding means used to bond said liquid-absorbent core material to said first and second inner surfaces, and further comprise first and second non-bonding regions having no bonding means; and
said first bonding regions face at least said second non-bonding regions, and said second bonding regions face at least said first non-bonding regions.

Abstract
A liquid-absorbent structure configured to prevent a liquid-absorbent core material from being unevenly distributed and thereby to assure that bodily fluids can be smoothly absorbed by the liquid-absorbent structure. According to one embodiment the present invention provides a panty liner that includes a topsheet lying on a side facing the wearer'"'"'s body, a backsheet facing the wearer'"'"'s garment and a liquid-absorbent structure sandwiched between these sheets. A first inner surface of a first sheet forming the liquid-absorbent structure is coated with adhesives to form a plurality of first bonding regions and a second inner surface of a second sheet is coated with adhesives to form a plurality of second bonding regions. Each of the first non-bonding regions lies between each pair of the first bonding regions, and each of the second non-bonding regions lies between each pair of the second bonding regions. The first inner surface and the second inner surface face each other, the first bonding regions face the second non-bonding regions via the liquid-absorbent core material, and the second bonding regions face the first non-bonding regions via the liquid-absorbent core material.
