  • Patent number: 5514121
    Abstract: A disposable absorbent article such as a diaper. The diaper has a topsheet, backsheet, and an intermediate core. Affixed to the outwardly oriented surface of the topsheet is an expulsive spacer. The spacer receives and collects fecal material from the wearer. The spacer may be removable from the diaper, or may be articulable relative to the diaper. By expelling the spacer from the diaper, fecal material can be easily flushed into the toilet, rather than discarded into a waste receptacle where it presents a sanitation hazard.

  • Patent number: 5514105
    Abstract: A resilient three-dimensional plastic web exhibiting reduced skin contact area and a fiber-like appearance and tactile impression. The web has a multiplicity of apertures therein, each being defined by a multiplicity of intersecting fiber-like elements interconnected to one another in the plane of a first surface of the web. Each of the fiber-like elements exhibits a substantially uniform generally upwardly concave-shaped cross-section along its length. The cross-section comprises a pair of convergent substantially linear portions which intersect one another at an end to form a vertex in the plane of the first surface of the web. This vertex reduces the skin contact area of the web providing a more comfortable feel for the user when the web is employed as a wearer contacting topsheet on an absorbent article. Furthermore, the web provides a substantially non-glossy visible surface as there is almost no substantially planar portion in its uppermost surface to reflect incident light to the viewer's eye.

  • Patent number: 5503715
    Abstract: Disclosed herein is a cellulosic fibrous structure having multiple regions distinguished from one another by basis weight. The structure is a paper having an essentially continuous high basis weight network, and discrete regions of low basis weight which circumscribe discrete regions of intermediate basis weight. The cellulosic fibers forming the low basis weight regions may be radially oriented relative to the centers of the regions. The paper may be formed by using a forming belt having zones with different flow resistances. The basis weight of a region of the paper is generally inversely proportional to the flow resistance of the zone of the forming belt, upon which such region was formed. The zones of different flow resistances provide for selectively draining a liquid carrier having suspended cellulosic fibers through the different zones of the forming belt.

  • Patent number: 5500451
    Abstract: A process for preparing high internal phase emulsions (HIPE) that can be polymerized to provide flexible, microporous, open-celled polymeric foam materials capable of absorbing aqueous fluids, especially aqueous body fluids such as urine. The HIPE is prepared using certain polyglycerol aliphatic ether emulsifiers that are less chemically complex and variable in composition than many prior HIPE emulsifiers, have higher levels of the desired interfacially active components, and have lower levels of components (e.g., sludge) that are insoluble or insufficiently soluble in the oil phase used to prepare the HIPE. These polyglycerol aliphatic ether emulsifiers provide HIPE having relatively uniform sized water droplets dispersed in the continuous oil phase.
