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.
