US Patent 7345215 Absorbent product with low friction zone

An absorbent product includes a backsheet, a topsheet and an absorbent core structure located therebetween, the core including a topsheet-facing surface which is fixedly attached to the topsheet. A low friction zone is arranged between the topsheet and the topsheet-facing surface in an area where said topsheet is not attached to the topsheet-facing surface, or a sheet is secured at a portion of its periphery to the topsheet and the low friction zone is placed above the topsheet. These arrangements alleviate skin damage.
