Abstract: A feminine hygiene article and method of making same so that back-attached wings have adhesive areas for attachment to an undergarment, that are substantially offset from the adhesive areas of the main body portion, also used to attach the undergarment.

Abstract: 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 (good for absorption performance) or a “M” 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.

Abstract: A novel method for manufacturing a layer of a laminated, disposable absorbent product, such as a fluid-permeable cover layer, an absorbent core layer or a fluid-impervious backing layer thereof, with a comparatively small amount of waste matter. The method comprises the steps of longitudinally cutting a continuous web of starting material according to a cyclic pattern constructed with line segments corresponding to the edge contour of the disposable absorbent product. The cutting operation divides the continuous web in two strips, each strip having a patterned longitudinal edge whose outline corresponds to the cyclic pattern. The strips are crossed and joined to one another in a parallel and in a phase relationship to form a compound web having longitudinal edges producing repeatedly the edge contour of the disposable absorbent product.

Abstract: A sanitary napkin with laterally projecting positioning tabs. The adhesive securement system of the sanitary napkin includes three adhesive zones in a spaced apart relationship, namely one zone on the main body of the sanitary napkin and one zone on the undergarment facing surface of each positioning tab. A quick-remove peelable protective layer covers the adhesive zones when the sanitary napkin is not in use. The protective layer includes a primary release strip extending longitudinally on the sanitary napkin to cover the adhesive zone on the main body and a transverse secondary release strip overlaying the adhesive zones on the positioning tabs. This arrangement allows removal of entire protective layer in a single peel-off stroke. The invention also relates to a method and apparatus for folding a positioning tab of the sanitary napkin over its main body during a packaging operation that inserts the sanitary napkin in a disposable pouch.

Abstract: A disposable absorbent product such as a sanitary napkin, a diaper, an adult disposable brief or an urinary pad, among others, including a liquid-permeable cover layer, and absorbent core and a liquid-impervious layer for preventing body exudate entrapped in the absorbent core from contacting the wearer's undergarment or skin. A secondary liquid containment structure for intercepting body exudate leaking past the side edges of the absorbent product is mounted underneath the liquid-impervious layer. The containment structure includes a transversely extending strip of absorbent material such as non-woven fabric, having longitudinal end portions forming liquid-acquisition zones. The central portion of the absorbent strip constitutes a reservoir layer for collecting the body exudate discharged on the liquid-acquisition zones.

Abstract: A highly absorbent and flexible calendered and perf-embossed cellulosic pulp fluff sheet for use in disposable absorbent products such as sanitary napkins, wound dressings, bandages, incontinence pads, disposable diapers and the like. The invention also extends to a method for manufacturing the highly absorbent and flexible pulp fluff sheet and its method of use in disposable absorbent products.
