Abstract:
The invention relates to absorbent structures for use in absorbent articles. The structures include a first region for distribution of fluid and a second region for storage of fluid. The first region contains materials, with a relatively high capillary desorption pressure, while the second region contains materials exhibiting a sufficiently high capillary absorption pressure efficiently drain the first region. Exemplary materials have a CSDH 50 of more than 40 cm, and a second region containing a material which satisfies at least one of following requirements: (a) an absorption capacity of at least 15 g/g at 35 cm (b) an absorption capacity of at least 15 g/g at 0 cm and an absorption efficiency of at least 55% at 40 cm; and (c) a Capillary Sorption Absorption height at 50% of its capacity at 0 cm absorption height (CSAH 50) of at least 35 cm.
Abstract:
The present invention relates to liquid impermeable moisture vapor permeable composite structure comprising a specific thermoplastic film which is thinly coated onto a support layer. The composite structures of the present invention can find a variety of applications, wherein moisture vapor permeability is desirable for example within absorbent articles such as diapers, sanitary napkins, panty liners and incontinence products, protective bedding covers, protective clothing and the like.
Abstract:
A disposable urine management device including a bag having an aperture which is surrounded by an adhesively-faced flange for releasable attachment to the uro-genital area of the wearer. An absorbent material is contained within the bag.
Abstract:
Described are absorbent members useful in the containment of body liquids such as urine. These absorbent members comprise at least one osmotic absorbent (preferably a hydrogel-forming absorbent polymer) and a high surface area material, and have a high capillary suction capacity. For purposes of the present disclosure, capillary suction capacity is measured in terms of the member's ability to uptake liquid at high capillary heights, which are generally encountered when the member is positioned in an absorbent article. In particular, capillary suction capacity is measured in terms of a member's capillary sorption absorbent capacity, which is measured in accordance with the Capillary Sorption method described in the Test Methods section.
Abstract:
A disposable absorbent article, such as a diaper, comprising a medium viscosity feces storage material having an improved ability to store in particular medium low viscosity feces.
Abstract:
Described are absorbent members useful in the containment of body liquids such as urine. The storage members have a high capillary suction capacity. For purposes of the present disclosure, capillary suction capacity is measured in terms of the member's ability to uptake liquid at relatively high capillary pressures, which are generally encountered when the member is positioned in an absorbent article. In particular, capillary suction capacity is measured in terms of a member's capillary sorption absorbent capacity, which is measured in accordance with the Capillary Sorption method described in the Test Methods section of the disclosure. The absorbent members may include an osmotic absorbent (preferably a hydrogel-forming absorbent polymer) or a high surface area material, or a combination thereof.
Abstract:
Disclosed is a thin, layered, absorbent structure comprising first and second layers of fibrous material and an intermediate layer comprising particles of a hydrogelling, absorbent material, in an amount exceeding 120 g/m.sup.2, and particles of a thermoplastic, polymeric, organic material; the first and second fibrous layers extend beyond the intermediate layer laterally to form longitudinal edge portions. The two fibrous layers are bound together with the intermediate layer between them by the melting of the particles of thermoplastic, polymeric, organic material and by means of a continuous line of adhesive extending longitudinally on each longitudinal edge portion.
Abstract:
A resealable pack having a body portion formed substantially of flexible sheet material and defining an article-receiving cavity. The body portion comprises a first end defined by an end wall and tapers to a second end spaced apart from the first end. The body portion also comprises a face in which is defined a dispensing opening. A resealable sealing member is secured to the body portion and, in a closed position, covers the opening in sealing contact with the body portion around the periphery of the opening. A plurality of sheet-form articles is disposed within the cavity in the form of a flattened roll, with one end of the roll being capable of extending through the opening.
Abstract:
A package for packs, for example packs of absorbent articles, each pack comprising a plurality of such absorbent articles and a wrapper of flexible material with a carrying handle at the top. The package comprises a plurality of packs disposed side by side and fixed together with adhesive tape, the adhesive tape being detachable without tearing the flexible material. Each handle is capable of supporting the weight of the entire package.
Abstract:
An absorbent element for absorbent articles comprised of hydrophilic fibers and a discontinuous, non-uniform layer of particles of absorbent hydrogelling material arranged on the upper surface of the element includes a deposition zone on which the absorbent hydrogelling material is distributed with an increased surface density.The zone of increased surface density of the absorbent hydrogelling material can preferably be located in different positions suitable for the different anatomical forms of the users, so as to ensure more effective sealing against the backflow of the liquid and thus ensure an improved feeling of dryness.
