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 'W' pattern. 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 pair of preferential bending zones extending along the longitudinal axis of the sanitary napkin and by a pair of longitudinal adhesive zones on the liquid-impervious barrier layer of the sanitary napkin, that register with the preferential bending zones. The longitudinal adhesive zones fasten the sanitary napkin to the undergarment at the areas at which the sanitary napkin is intended to fold when subjected to lateral compression. This feature allows the napkin to fold and adopt a desired three-dimensional deformation profile in a predictable manner when laterally compressed.

Thin sanitary napkin allowing for controlled deformation when in use

The invention provides a sanitary absorbent article, such as a feminine protection device, having a fibrous, liquid permeable body-facing cover layer, and an absorbent system, which exhibits particular rewet characteristics when subjected to mechanical stress. The sanitary absorbent article has a thickness of less than or equal to 5 mm, a capacity of at least 18 grams, a rewet potential of less than or equal to 0.8 grams, and a flexural resistance of less than 700 g.

Sanitary napkin with improved liquid retention capability

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

A sanitary absorbent napkin has a laminate structure coprising a first liquid-permeable sheet of material, a second liquid-permeable sheet of material disposed adjacent the first sheet, and an absorbent member for absorbing liquid and disposed adjacent to the second sheet. The second sheet is arranged to receive the liquid deposited on the first sheet and to transfer liquid to the absorbent member. The napkin has a thickness of less than or equal to about 5 mm, when dry, and a penetration time of less than 15 seconds.

Sanitary absorbent napkin

A receptacle containing a plurality of sanitary absorbent articles that are individually packaged. On each package is applied a visual reference system. The visual reference system includes a first and a second elements of information. The first element of information is indicative of a scale of reference establishing a range of values of a certain characteristic of the sanitary absorbent article in the package. The second element of information is indicative of a certain degree or level on the scale of reference. The certain characteristic can be the liquid absorption capacity of the sanitary absorbent article.
