Abstract:
An absorbent easily rendered three-dimensional in the central region by water absorption is composed of a sheet-like absorbent having regions where a highly absorptive component is present and regions where it is absent, these presence and absence regions parallelly extending lengthwise of a sheet-like base material and alternating with each other, the sheet-like base material being turned back along a bending line in the highly absorptive component absence regions of the sheet-like absorbent, there being at least one band-like portion of multilayer construction where the highly absorptive component presence regions are superposed in a plurality of layers.
Abstract:
Disclosed herein is a liquid absorbent material that is particularly useful as a liner material for personal care absorbent articles such as diapers, training pants, incontinence garments, sanitary napkins, bandages and the like. The material contains a plurality of peaks across its surface at spaced-apart intervals separated by channels. Disposed within the peaks is a liquid absorbing material capable of absorbing body exudates and liquids in general. Due to the materials and the nature of the construction of the present invention, when used as a liner material for personal care absorbent articles such as diapers, it tends to reduce the total surface area in contact with the infant's skin and it also provides a plurality of air channels within the diaper from the front waistband to the back waistband of the diaper thereby providing a path for increased air circulation. The material of the present invention has other uses as, for example, a packing or liner material for packaging and shipping materials containing liquids. In addition, the peaks can contain other additives such as soaps so the material can be used as a wash pad or cloth.
Abstract:
Absorbent articles including a compressed tablet are generally described. The compressed tablet of the present invention is configured to expand toward the skin of the wearer (i.e., in the z-direction of the absorbent article perpendicular to the plane of the absorbent article) upon contact with a liquid. However, the expansion of the compressed tablet is substantially limited to the z-direction. That is, the compressed tablet does not substantially expand in any direction parallel with the plane of the article (i.e., the x- and y-directions). As such, the compressed tablet does not significantly interfere with the absorbent capabilities of the absorbent article. Thus, the compressed tablet can be included within conventional absorbent articles without significantly sacrificing the absorbency characteristics of the article.
Abstract:
An absorber in a sheet form, characterized in that it comprises a concave portion and a convex portion and exhibits a three−dimensional change of the shape thereof through absorption of water, wherein the difference in level of the concave portion and the convex portion of A mm in a non−absorption state (dry state) is grown to 2A mm or more after absorption of water, due to the protuberance by absorption of and swelling with water.
Abstract:
A disposable menstrual undergarment configured to be worn as a panty for absorption of menstrual fluids. The panty includes an exterior layer of breathable non-porous material, a middle layer of absorbent materials, and a removable interior layer of absorbent materials positioned on the middle layer and within the front portion, rear portion, and the crotch portion of the undergarment. At least one strip of absorbent materials is positioned along each interior portion of each leg opening. The disposable menstrual undergarment provides for absorption of fluids for young females and/or for adults needing special assistance, with an interior layer that is removable after becoming soiled, while providing additional layers of absorbent materials within the undergarment for absorption of fluids for an extended time until a replacement undergarment is obtained.
Abstract:
Described is an absorbent article (20) having a moisture barrier (40) and an absorbent assembly (42) disposed on the moisture barrier (40). In one embodiment, fecal containment members (60) of the absorbent article are positioned transversely outward of the absorbent assembly (42) between the absorbent assembly (42) and each longitudinal side edge (28) of the article. The fecal containment members have a wet compression recovery of at least about 85 percent and a mean pore size of at least about 1.5 millimeters.
