An absorbent product has a fluid permeable top sheet, a fluid impermeable backing sheet, and an absorbent core having an upper side, a bottom side, two longitudinally running sides and two laterally running sides. The product further has two longitudinally running barrier flaps at the longitudinally running sides of the absorbent core. The top sheet covers the upper side of the absorbent core. The top sheet, with the upper side of the absorbent core, also covers the longitudinally running sides of the absorbent core and part of the bottom side of the absorbent core, the top sheet extending between at least a portion of the bottom side of the absorbent core and the backing sheet. The top sheet is connected to the backing sheet at the bottom side of the absorbent core. The barrier flaps are connected to the backing sheet at the longitudinally running sides of the absorbent core.

Absorbent article

The invention relates to a material structure for use in absorbent articles, and an absorbent article comprising such a material structure. The material structure () comprises a liquid-pervious cover layer (), a liquid-impervious cover layer (), and an absorbent structure () enclosed between the cover layers (). Thereby, the absorbent structure () comprises polylactide fibres or filaments, the properties of which contributing to a rapid acquisition of liquid through the liquid-pervious cover layer () for absorption into the absorbent structure () also when the material structure () is subjected to repeated wettings. The invention can advantageously be applied within the field of absorbent hygiene articles, such as different types of diapers and incontinence guards, sanitary napkins, pantyliners, and the like.

Material structure for use in absorbent articles, and an absorbent article comprising such a material structure

An oblong absorbent article that includes a liquid-impermeable bottom sheet, and upper liquid-permeable sheet and an absorbent body disposed between these sheets, and on each side of the longitudinal center line of the upper sheet at least one longitudinal elastic liquid barrier having at least the free edge treated with a non-adhesive sealing medium which partly fills out the pores formed between the free edge and the abutment surface on the wearer, and/or which, when the article is donned, increases around said abutment surface, the wetting angle of the liquid to the skin. An absorbent article that includes an essentially liquid-impermeable top sheet above an absorbent body enclosed between an upper liquid-permeable sheet and a liquid-impermeable sheet, the top sheet being provided with elastic for shaping the article to the wearer's body and incorporating apertures intended to register with the anus and the urethra orifice of the wearer in use, around which apertures elastically puckered sealing edges are disposed, at least one sealing edge being coated with the sealing medium.

Absorbent article incorporating liquid barriers with sealing coating

An absorbent article, such as a diaper, a pants-type diaper, an incontinence protector or a pants-like sanitary napkin, having a front part, a rear part and an intermediate central part. The article includes an absorbent body enclosed between an inner, liquid-permeable sheet and a liquid-impermeable outer sheet, and fastener devices for releasably connecting side-portions of the front and rear parts. The fastener devices are made of a renewable material. The fastener devices are welded to at least one of the sheets of the article and the fastener devices and the sheets are made of a material having a glass transition temperature which lies between 50-60&deg; C. and a melting point which lies between 140-180&deg; C., preferably between 150-175&deg; C.

Diaper that includes weldable fastener devices

An absorbent article includes a liquid-permeable upper sheet, a liquid impermeable bottom sheet, and an absorbent body between the bottom sheet and the upper sheet, and at least one longitudinally extending liquid barrier comprising an elongated elastic element and an elongated, essentially liquid-impermeable and inelastic material on each side of a longitudinal center line. A liquid impermeable top sheet with an aperture intended to lie in register with a wearer's anus and urethral orifice may also be included. A prestretched elastic band is attached to either an edge of an inelastic material of the liquid impermeable barrier or to the aperture-defining edge of the liquid permeable top sheet. When the article is donned, the elastic device will lie against a wearer, with a free part facing toward the longitudinal center line and a stretchable, puckered sealing edge facing outward from the longitudinal center line.

Longitudinal puckered-edge liquid barriers for absorbent articles

A diaper or incontinence guard includes a waist belt ( ) and an absorbent unit ( ) with a front part ( ), a rear part ( ) and an intermediate crotch part ( ). Fastener devices ( and respectively) are disposed at the front end and the rear end of the absorbent unit and can be fastened to the belt. Each of the front and rear ends of the absorbent unit ( ) includes a respective central fastener device ( and ) that is located on the longitudinal symmetry axis (A&mdash;A) of the unit, and two lateral fastener devices ( and respectively) located on respective sides of the axis.
