A sanitary absorbent article is disclosed which is intended to be worn against a pudendal region of a user. The sanitary absorbent article is thin, i.e. having a thickness equal to or less than 5 mm and comprises a body contacting surface with at least one protrusion on the body contacting surface. The protrusion has a height H of at least 0.5 mm, and an equivalent width W. The protrusion also includes a ratio W/H ranging from about 2 to about 10.

Thin sanitary napkin having protrusions

A sanitary napkin is disclosed that is thin, highly absorbent and has a flexibility selected to provide good comfort potential and at the same time reduce the likelihood of uncontrolled deformation, known as bunching. In a specific example, the sanitary napkin has a cover layer, an absorbent system and barrier layer. The absorbent system has superabsorbent material in a matrix of cellulosic fibers.

Thin sanitary napkin having a flexibility selected to provide a good comfort potential while reducing bunching

The present sanitary napkin is thin (less than 4 mm in thickness), highly absorbent and has a flexural resistance which provides controlled deformation when in use, namely the assumption of a &ldquo;W&rdquo; pattern (good for absorption performance) or a &ldquo;M&rdquo; pattern (which enhances comfort). This controlled deformation provides a good comfort potential and simultaneously reduces the likelihood of bunching due to compression forces exerted laterally against the napkin by the thighs of the wearer. The sanitary napkin is characterized by a flexural resistance of not less than about 400 g. The sanitary napkin has a cover layer, a barrier layer and an absorbent system having at least one preferential bending zone which allows the napkin to adopt a certain three-dimensional deformation profile in response to lateral compression.

Thin sanitary napkin capable of controlled deformation when in use

The present invention provides a sanitary napkin that is thin (less than 5 mm in thickness), highly absorbent and has a lateral flexibility allowing for controlled deformation when in use, namely the assumption of a &ldquo;W&rdquo; pattern (good for absorption performance) or a &ldquo;M&rdquo; pattern (which enhances comfort). This controlled deformation provides a good comfort potential and simultaneously reduces the likelihood of bunching due to compression forces exerted laterally against the napkin by the thighs of the wearer. In a specific example, the sanitary napkin is characterized by a lateral stiffness of not less than about 400 g and comprises a cover layer, a barrier layer and an second absorbent layer having at least one preferential bending zone which allows the napkin to adopt a certain three-dimensional deformation profile in response to lateral compression.
