Abstract: The present invention relates to a menstrual fluid management device that is attached directly to the wearer by use of an adhesive. The device allows for direct and immediate containment of menstrual and other vaginal discharges. In particular, the device improves the prevention of soiling over devices already known in the art by using an attachment flange around an orifice which has a shape of the generally oblong dimensions, where the width in the rear end of the orifice is wider than at the front end, thereby improving the circumscription of the female genitalia and the sealing along the flange to the skin of the wearer.

Abstract: The applicator is used for a placement of an excreta management device on a wearer. The applicator has a longitudinal centerline, a transverse centerline, a device facing surface and an opposing surface. The applicator comprises a handle disposed at transverse ends, a pressure portion disposed along the longitudinal centerline, a middle portion disposed between the handle and the pressure portion and a spacer. When the applicator folded into a pair of right and left pieces along the longitudinal centerline, the spacer is inserted between the right and left pieces. The pressure portion presses the excreta management device toward the wearer's skin during the use of the applicator. The opposing surface of the right piece and the opposing surface of the left piece are separated from one another at the middle portion by the spacer when the applicator is folded.
Abstract: The present invention relates to articles, preferably disposable absorbent articles like sanitary napkins and pantiliners, which comprise a chitosan material and an anionic absorbent gelling material. Such disposable absorbent articles deliver improved odor control performance and improved fluid handling properties/absorption performance, especially in case of electrolytes-containing fluids like menses.

Abstract: The present invention relates to articles, preferably disposable absorbent articles like sanitary napkins and pantiliners, which comprise a cationic polysaccharide, preferably chitosan material, and silica. Such disposable absorbent articles deliver improved odor control performance (synergistic odor reduction) and improved fluid handling properties/absorption performance. In one embodiment of the present invention, articles are provided which comprise crosslinked silica-cationic polysaccharides. These articles deliver not only improved odor control and fluid handling properties when in use but are able to maintain these properties even upon prolonged wearing time, typically upon ageing of the bodily fluid in the articles and/or upon subsequent fluid discharge in the articles.

Abstract: An absorbent article containing a liquid pervious topsheet coated with a lotion composition is disclosed. The lotion composition comprises a plastic or fluid emollient such as mineral oil or petrolatum, an immobilizing agent such as a fatty alcohol or paraffin wax to immobilize the emollient on the surface of the topsheet, and optionally a hydrophilic surfactant to improve wettability of the coated topsheet. Because the emollient is substantially immobilized on the surface of the topsheet, less lotion is required to impart the desired therapeutic or protective lotion coating benefits.

Abstract: A catamenial tampon in the form of a soft, conformable, hollow bag which is capable of being inserted digitally or through the use of a unique applicator. The tampon has an outer surface, an inner surface, a head portion and a trailing portion. The inner surface of the tampon defines an interior of the tampon wherein the head portion is closed and the trailing portion defines an opening into the interior of the tampon. The tampon may have a shape modulus of compression of less than 0.05 pounds force. The tampon preferably includes a removal string, which can be attached to the inside or outside surface of the tampon.

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: Catamenial tampons having particularly desired expansion force characteristics are shown. The tampons comprise a mass of absorbent material which is fluid expanding. The tampons exert an X Dimension Force of at least about 400 grams, and a Z Dimension Force of less than about 200 grams. Alternatively, the ratio of the X Dimension Force to the Z Dimension Force is from about 10 to about 50.
