    Abstract: The present disclosure is directed, in part, to an absorbent article that comprises an absorbent core disposed at least partially intermediate a topsheet and a backsheet and a core wrap enclosing an absorbent material. The core wrap comprises a first material and a second material. The first material forms a C-wrap at least partially around the second material. The absorbent material comprises at least 80% of superabsorbent polymers by weight of the absorbent material. The absorbent core comprises a channel substantially free of the superabsorbent polymers, at least partially oriented in a longitudinal direction of the article, and comprising an arcuate portion. The channel has lateral widths taken parallel to a lateral axis of the article. The profile of the lateral widths of the channel over a longitudinal length of at least 50 mm of the channel taken along the longitudinal axis is substantially constant.

    Abstract: An absorbent product has a top sheet, an absorbent core and a back sheet. The absorbent core includes 40% by weight or more of high absorbent resin powder and it is possible to slim down the absorbent core while keeping a sufficient amount of absorption to thereby achieve slimming down of the absorbent product. A top sheet lower part contacting the high absorbent resin powder in the absorbent core includes hydrophilic fibers having water retention characteristics, and moisture is temporarily retained in the top sheet lower part before reaching the absorbent core and rapidly disperses in a range facing the absorbent core of the top sheet lower part. As a result, it is possible to reliably absorb the moisture of excrement in the absorbent core and to simplify a structure of the absorbent product.

The guard has a transverse direction and a longitudinal direction and is divided by a transverse dividing line into a front region with a front transverse edge and a rear region with a rear transverse edge. The front region has a greater maximum extension in the transverse direction than the maximum extension of the rear region in the transverse direction, and the longitudinal extension of the rear region is 10-60% of the longitudinal extension of the guard.

  • Patent number: 8395014
    Abstract: The present invention relates to a system suitable for monitoring multiple leakage events such as wetting of a diaper or alike sanitary product. The system includes two or more than two electrodes that are supported in a spaced apart relationship and a liquid permeable substrate between the electrodes that lacks or has a low capacity for holding or storing liquid. In the event of liquid leakage, an electrical bridge connecting the electrodes can be formed by the liquid, and before the product becomes saturated liquid can freely drain from the permeable substrate and disconnect the electrodes. Upon further liquid leakage, electrical connection between the electrodes can be reformed indicating multiple liquid leakage events. In the situation where the sanitary product becomes saturated and liquid is prevented from draining from the permeable substrate, the electrical connection will continue, indicating that the sanitary product requires changing.

  • Publication number: 20130023845
    Abstract: The present invention provides a bodily fluid-absorbent structure improved so as to facilitate bodily fluids to disperse in a thickness direction of the structure. Core material of a bodily fluid-absorbent structure is formed of an aggregation of fluff wood pulp fibers. The aggregation has a basis mass in a range of 150 to 500 g/m2 and a specific volume in a range of 3 to 20 cc/g. In the aggregation, a relationship between horizontal orientation index IH and specific volume VSP of fluff wood pulp fibers is represented by a formula as follows: IH is less than or equal to ?0.099VSP+2.4.

  • Patent number: 8357132
    Abstract: A urine capturing assembly includes a sleeve that has an upper edge, a lower edge and a perimeter wall extending between the upper and lower edges. The upper and lower edges define openings in the sleeve. A penis is positionable in the sleeve to direct urine from the penis toward the lower edge. A pouch has an open top end. The pouch is integrally coupled to the perimeter wall and the top end is positioned adjacent to the upper edge of the sleeve. A scrotum is positionable in pouch through the top end. A conduit is fluidly coupled to and extends between the sleeve and the pouch to direct urine held in the pouch into the sleeve. A collection bag is fluidly couplable to the lower edge of the sleeve to collect and retain urine.

  • Publication number: 20130012902
    Abstract: A wound dressing can include a backing layer, a facing layer which is permeable for wound exudate and blood and which, when in use, is in contact with the wound, and an absorbent core. The backing layer and the facing layer can be joined together in order to form a pouch. The absorbent core can be located within the pouch and can include at least a first layer and a second layer. The first layer can be located closer to the facing layer than the second layer. The first layer can be configured to provide a flow of liquid predominantly in a direction perpendicular to the extension of the facing layer. The second layer can be configured to provide a flow of liquid predominantly in a direction parallel to the extension of the facing layer.
