ABSORBENT CORE, ARTICLES COMPRISING SAID CORE, AND METHODS OF MAKING
An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.
ERGONOMIC DISPOSABLE ABSORBENT GARMENT WITH ABSORBENT CORE ASSEMBLY
A disposable undergarment is disclosed. The undergarment includes a chassis and an absorbent core assembly. The chassis includes a front section, a crotch section and a rear section and elastic threads in those sections. The absorbent core is located in the crotch section, with portions of it extending into the front and rear sections. The core assembly includes a first or upper section of including plural pockets of a free slow acting but high absorbency SAP, and a second or underlying second section including plural pockets of a free fast acting by lower absorbency SAP. The SAP of the upper and lower sections exhibits various characteristics to facilitate to effective and efficient absorption of a fluid insult into the core assembly.
Absorbent core, articles comprising said core, and methods of making
An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.
Absorbent article with advantageously channeled absorbent core structure
A disposable absorbent article having a longitudinally channeled absorbent core structure is disclosed.
Absorbent article with multi-use protection layer
An absorbent article which can be more readily adaptable to meet the needs of the individual wearer of the absorbent article. The absorbent article can have a topsheet layer, a backsheet layer, and an absorbent core between the topsheet layer and the backsheet layer. The backsheet layer can have a garment attachment mechanism located on a garment facing surface of the backsheet layer. The absorbent article can further have a protection layer situated over and engaged with the garment attachment mechanism. The protection layer can be capable of being at least partially dis-engaged from the garment attachment mechanism. The protection layer of the absorbent article can be utilized by the wearer to provide additional area of coverage as deemed suitable by the wearer of the absorbent article.
Absorbent articles with improved core
An absorbent article including a wearer-facing topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet, characterized in that the absorbent core includes: a first absorbent layer comprising a first substrate, a layer of first superabsorbent polymer particles deposited on the first substrate, and a fibrous layer of thermoplastic adhesive material covering the layer of first superabsorbent polymer particles; a second absorbent layer, the second absorbent layer comprising a second substrate and a mixed layer deposited on the second substrate, the mixed layer comprising a mixture of second superabsorbent particles and cellulosic fibers, the first absorbent layer and the second absorbent layer being combined together such that at least a portion of the fibrous layer of thermoplastic adhesive material of the first absorbent layer contacts at least a portion of the mixed layer of the second absorbent layer, and wherein the first absorbent layer is placed closer to the topsheet than the second layer.
Disposable pull-on diaper
A disposable pull-on diaper that keeps in close contact with a wearer's crotch region includes a lower torso cover and an absorbent chassis. The absorbent chassis has a front end portion overlapping a front waist region of the lower torso cover and a front end portion of the front end portion is joined to an elastic region in the lower torso cover. A front end adjoining portion of the front end portion is not joined to the elastic region. An area in the absorbent chassis being adjacent the front end adjoining portion on the side of the crotch region is joined to an inelastic region defined on the side closer to the crotch region than to the elastic region. The absorbent body contained in the absorbent chassis extends at least from the crotch region to the front end adjoining portion. The front end portion in the front end portion of the absorbent chassis is defined by a portion of the cover sheet wrapping the absorbent body which extends outward beyond the absorbent body.
Feminine night pad
A feminine night pad is described having multiple layers of absorbent material selectively stacked in a manner to define a body portion and a central portion. Each portion is laid upon an upper surface of a trim member including an impermeable sheet. The body portion has a plurality of absorbing layers set in from the edge of the trim member. The central portion is built upon the body portion and includes one or more layers of additional absorbent material. The trim member is covered in absorbent material and extends around the entire periphery of the body portion. The trim member and corresponding portions are formed into a triangular shape to better conform to a woman's body.
Absorbent articles with channels and/or pockets
The present disclosure is directed, in part, to an absorbent article having a front waist edge, a rear waist edge longitudinally opposing the front waist edge, a longitudinal axis extending from a midpoint of the front waist edge to a midpoint of the rear waist edge, a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed at least partially intermediate the topsheet and the backsheet. The absorbent core having superabsorbent polymers and a channel network substantially free of the superabsorbent polymers. The channel network having a perimeter channel, a first longitudinal channel inboard of the perimeter channel, a second longitudinal channel inboard of the perimeter channel, and one or more connecting lateral channels. The one or more connecting lateral channels connect one of the first longitudinal channel to the second longitudinal channel or the perimeter channel to the perimeter channel.
FLUID DISTRIBUTION MATERIAL FOR ABSORBENT ARTICLES
A fluid distribution material for use in an absorbent article includes a formed film layer having a user-facing side and a garment-facing side opposite the user-facing side. The formed film layer includes a plurality of apertured protuberances arranged in a pattern having 10 to 40 protuberances per linear inch. Each of the protuberances includes a continuous sidewall extending from the user-facing side. The garment-facing side has a plurality of apertures aligned with the plurality of apertured protuberances and land areas in between the apertures. A nonwoven layer is laminated to the garment-facing side of the formed film layer. The nonwoven layer includes a plurality of continuous fibers extending across the land areas and the plurality of apertures of the formed film layer and attached to the land areas at bond sites. The fluid distribution material has a compressibility of less than 10% between pressures of 0.21 psi and 0.60 psi.
