  • Patent number: 7195810
    Abstract: An absorbent sheet made from an air-laid fiber web includes a functional emboss pattern of a continuous (wave-like) shape extending in the machine direction of the sheet. The emboss pattern defines a plurality of compressed regions operative to preferentially convey sorbed liquid away from the point of insult to prevent product failure. The sheet is particularly useful as absorbent core material within a multi-layer absorbent pad. In a further aspect of the invention, there is provided a method of making absorbent sheet utilizing an emboss roll provided with radially projecting circumferential sinuate bosses.

  • Patent number: 7175727
    Abstract: A method for making absorbent pads for various absorbent articles is provided. A strip of the absorbent web material is conveyed along a machine direction, the absorbent web material having a generally first constant cross-direction width and generally first uniform basis weight. Longitudinally defined portions of the web material are stretched in the cross direction so as to define longitudinal sections having a wider cross-direction width and decreased basis weight alternately spaced between longitudinally extending sections of the web material having a lesser cross-direction width and greater basis weight. The web is released eventually cut in a cross direction into individual absorbent pads such that each pad has a crotch section corresponding to the longitudinal section having the lesser cross-direction width and greater basis weight and at least one of a front section and back section corresponding to the wider cross-direction width and decreased basis weight.

    Abstract: A cloth-like, flexible mechanical fastener including a flexible layer and at least one fastener island, and methods of making the same. The fastener island has a planar perimeter edge, a mechanical fastening material, and a backing material attached to the mechanical fastening material. The backing material is embedded within the flexible layer and the planar perimeter edge is surrounded by the flexible layer. Accordingly, the mechanical fastener offers an improved flexibility and a cloth-like presentation. The improved flexibility and cloth-like presentation reduce the potential for the wearer to be exposed to coarse edges or creases, thereby lowering the possibility of red-marking or irritation of the skin. Moreover, the flexibility of the fastener allows the fastener to better accommodate the movement of the wearer, providing more reliable securement. The cloth-like, flexible mechanical fastener may be of particular use in combination with disposable absorbent articles to secure the article about a wearer.

    Abstract: An extensible absorbent article or garment has an extensible top sheet layer for facing the body of the wearer; an extensible back sheet layer for an exterior layer facing away from the body of the wearer; and an absorbent core layer located between the top sheet and the back sheet. The absorbent core has a tissue layer acting as a boundary layer or web between the top sheet and the fluff pad of the absorbent core. The tissue web of the absorbent core has an adhesive discontinuously applied thereto for attachment to the top sheet or other extensible layers to avoid tearing the tissue when the extensible layers expand. The tissue web may further be pleated to allow for its extensibility. The discontinuity of the adhesive then allows the pleats to perform their expansion function unbound and thus the tissue can extend without tearing, thereby maintaining the integrity of the tissue barrier.

  • Patent number: 6603052
    Abstract: A fluid absorbent article for surgical applications includes a top layer including an apertured film having a plurality of apertures formed therein. Each aperture includes a base and an apex with the aperture base oriented in an upper surface of the top layer and the apex positioned a depth below the base and upper surface. An absorbent layer includes an absorbent media positioned to underlie the top layer generally coextensive with the top layer and receive fluids passing through the top layer. The absorbent media is operable for dispersing and containing the fluid within the article. Bases of the apertures have a plurality of generally straight sides and are positioned with respect to the upper surface to present a plurality of different angles to fluid flowing on the upper surface to hinder and divert the fluid so that it more readily passes through the apertures to the absorbent layer.

  • Patent number: 6580015
    Abstract: An absorbent composition comprising an uncrosslinked, high molecular weight polymer, wherein the uncrosslinked, high molecular weight polymer is treated by a means to effectively insolubilize the uncrosslinked, relatively high molecular weight polymer such that the absorbent composition exhibits desirable absorbent properties. In particular, the absorbent composition has the ability to absorb a large quantity of liquid. The absorbent composition is useful in disposable absorbent products, such as those disposable absorbent products that are used to absorb bodily liquids. Suitable polymers include polyethylene oxide, poly(acrylic acid), poly(vinyl alcohol), and poly(vinyl pyrrolidone) wherein the polymer has a weight average molecular weight that is greater than about 1,000,000.

  • Patent number: 6579275
    Abstract: A pant-like, disposable absorbent article includes an absorbent chassis, a pair of opposed side panels, at least one releasable joint and at least one folded fastenery. The absorbent chassis defines a pair of laterally opposed side edges and a pair of longitudinally opposed waist edges. The side panels extend between the side edges of the absorbent chassis to define a waist opening and a pair of leg openings in the pant-like disposable absorbent article. Each of the opposed side panels defines a first side margin which is permanently attached to the side edge of the absorbent chassis in one waist region of the absorbent article to provide a permanent joint. At least one of the opposed side panels further defines a second side margin opposite the first side margin which is releasably attached to the side edge of the absorbent chassis in the other waist region of the absorbent article to provide a releasable joint.

  • Patent number: 6572595
    Abstract: A disposable absorbent garment includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet. The topsheet, the backsheet, and the absorbent core form a layered assembly including a front region, a back region, and a crotch region disposed between the front region and the back region. The garment is characterized by a vertical longitudinal plane that extends substantially centrally through the front, back and crotch regions. Each of the front and back regions includes a pair of ear portions extending in substantially opposite lateral directions with respect to the longitudinal plane. Each ear portion is a breathable stretchable layer assembly having a plurality of vent sites. Further, each ear portion includes an outer layer that is an extension of the backsheet and which extends laterally to the side edge of the ear portion, and an inner layer that is an extension of the topsheet and which also extends laterally to the side edge of the ear portion.
