  • Patent number: 5021051
    Abstract: A disposable absorbent article, such as a disposable diaper, having barrier leg cuffs. The barrier leg cuffs have a distal edge which is spaced from the proximal edge so as to provide a barrier against leakage. The barrier leg cuff has a portion affixed to the diaper so that the spacing between the barrier leg cuffs is increased in selected portions to reduce irritation of the genetalia and to provide a larger area to receive bodily discharges.

  • Patent number: 5019065
    Abstract: A disposable absorbent article with a combination mechanical and adhesive tape fastener system. The tape fastener system preferably comprises a tape tab comprising a first fastening element joined to and disposed on a first area of the tape tab and adhesive associated with and disposed on at least a second area of the tape tab. The adhesive not only secures the tape tab to the body portion of the absorbent article to provide a side closure but also secures the absorbent article in its disposal configuration so as to prevent the contents of the soiled absorbent article from spilling or leaking out of the absorbent article. Preferably, a portion of the adhesive is disposed subjacent the first fastening element to join the first fastening element to the tape tab.

  • Patent number: 5007906
    Abstract: A sanitary napkin having a top sheet and an absorbent core associated with the topsheet is disclosed. The topsheet and associated core are decoupled from the backsheet of the sanitary napkin so that the topsheet and backsheet may be separated in the Z-direction. The sanitary napkin has a joined transverse edge connecting the top sheet and backsheet and forming a hinge to facilitate the Z-direction separation. The sanitary napkin further controls the amount of separation of the topsheet and associated core from the backsheet. A preferred way to control the amount of separation of the topsheet and associated core from the backsheet is longitudinally oriented pleats.

  • Patent number: 4990147
    Abstract: A disposable absorbent article, such as a diaper, having a liquid impervious backsheet, a urine pervious liner, and absorbent core intermediate the backsheet and liner is disclosed. The liner has a passageway to allow communication of solid waste materials to the core, thereby isolating such waste from the skin of the wearer. The liner, is at least partially composed of elastic panels. The elastic panels register the passageway with the anal opening to minimize the size of the passageway and prevent unnecessary exposure of the skin to the solid waste materials.

  • Patent number: 4919756
    Abstract: A method of and apparatus for adjusting the impact angle of a doctor blade are provided to at least partially offset negative effects of doctor blade wear. For example and not by way of limitation, in papermaking machines for making creped tissue paper, a negative effect of progressive doctor blade wear is progressive diminution of machine-direction tensile strength of the paper, all other operating factors being constant. That is, machine-direction tensile strength of the paper is inversely related to doctor blade wear which wear is, generally speaking, directly related to operating time. This progressive lessening of the paper's machine-direction tensile strength can be at least partially offset or compensated for by adjusting the impact angle of the doctor blade.

  • Patent number: 4919351
    Abstract: An improvement in web converting rewinders of the type which include a perforator cylinder, and a bedroll/chop-off roll combination comprising a set of chop-off blades, some of which chop-off blades are disposed on the bed roll, and some of which are disposed on the chop-off roll; and in which a running web is forwarded from an unwinding parent roll, and is converted into consumer product rolls such as, for example, tear-separable multi-sheet rolls of toilet tissue or paper towels. The improvement comprises parallel-motion chop-off blades which can be more closely spaced than in prior art chop-off blades, and thus induce greater stretching and more positive breaking of the web; and, preferably, the chop-off blades are disposed to act on a longer machine-direction-length of the running web than contemporary rewinders to enable more positively inducing roll endings by breaking along transverse lines of weakening rather than by inducing ragged transverse tears of the web.

  • Patent number: 4909803
    Abstract: A disposable absorbent article for absorbing liquids, particularly body fluids such as urine. An absorbent core is encased in an outer covering layer to which flaps are connected along the longitudinal sides at a proximal edge. The flaps also have a distal edge which is displaced from the absorbent core means. The flaps are elasticized to render the distal edge elastically contractible so that the flap is gathered.

  • Patent number: 4904440
    Abstract: Apparatus for and methods of forming airlaid fibrous webs having a multiplicity of layers and/or discrete particles of absorbent gelling material dispersed through at least a portion of the web. The apparatus is of the type which includes a laydown drum having a foraminous forming element, a primary vacuum chamber, and a dusting layer vacuum chamber; a primary hood; and a dusting layer hood. The dusting layer of fibers formed on the laydown drum acts to block the passage of particles or fibers entrained in a first fiber stream which is airlaid over the dusting layer so as to minimize equipment plugging problems and the loss of particles or fibers through the foraminous forming element. The primary vacuum chamber of the laydown drum preferably spans the primary hood and a portion of the dusting layer hood so that the dusting layer is not sheared off, damaged, or destroyed as the laydown drum rotates to the position where the first fiber stream is deposited over the dusting layer.

  • Patent number: 4900317
    Abstract: Disposable diapers provided with breathable leg cuffs. Disposable diapers comprise a topsheet, an absorbent element, and a backsheet. The leg cuff of a disposable diaper is that part of the diaper which fits about the wearer's leg. Extensions of the backsheet can be used to form cuffs which are frequently elasticized. In the present invention the cuffs are formed of a material which allows passage of vapor ("breathes") while tending to retard the passage of liquid. Apertured thermoplastic films are examples of such materials. Certain advantages accrue in cuffs which are permeable to vapor in their distal portions and impermeable in the portions adjacent the absorbent element. If the disposable diaper has a breathable backsheet, the cuffs are constructed to be more permeable to vapor per unit area in their breathable portions than is the backsheet.

  • Patent number: 4892536
    Abstract: A disposable absorbent article, such as a diaper, having a liquid impervious backsheet, a urine pervious liner, and absorbent core intermediate the backsheet and liner is disclosed. The liner has a passageway to allow communication of solid waste materials to the core, thereby isolating such waste from the skin of the wearer. The liner is longitudinally contracted by elastic strands disposed longitudinally nonadjacent the passageway, improving the fit of the article to the wearer without sacrificing leakage protection and allowing various sections of the article to assume independent functions.
