  • Patent number: 5699911
    Abstract: A package for containing hygienic articles. The package has a dispensing aperture covered by a refastenably closable flap. The flap overlaps the dispensing aperture, to minimize external contamination. The aperture is made by a cut-out, leaving an opening in the material used to form the package. A separate retaining band is added to decrease the size of the opening so that the desired overlap can be maintained independent of the cut-out used to form the opening or the flap. The package is intact as presented to the user, and may completely enclose the hygienic articles after the first use of a hygienic article.

  • Patent number: 5698076
    Abstract: Fibrous cellulose materials useful in the manufacture of soft, absorbent paper products such as paper towels, facial tissues, and toilet tissue are disclosed. The paper products contain a vegetable oil based quaternary ammonium chemical softening compound. Examples of preferred vegetable oil based quaternary ammonium chemical softening compounds include diester di(oleyl)dimethyl ammonium chloride (DEDODMAC) (i.e., di(octadec-z-9-eneoyloxyethyl)dimethyl ammonium chloride) derived from canola oil and/or high oleic safflower oil. Variables that need to be adjusted to maximize the fluidity of vegetable oil based acyl groups include the cis/trans isomer ratio or the Iodine Value (IV) of the fatty acyl groups. The tissue softness is further enhanced by controlling the purity of the fatty acyl groups and the di-substituted versus mono-substituted long chain hydrocarbyl substituent ratio in the quaternary ammonium compounds.

  • Patent number: 5692939
    Abstract: Absorbent foam materials that are capable of acquiring and distributing aqueous fluids, especially discharged body fluids such as urine. These absorbent foams combine relatively high capillary absorption pressures and capacity-per-weight properties that allow them to acquire fluid, with or without the aid of gravity. These absorbent foams also give up this fluid efficiently to higher absorption pressure storage materials, including foam-based absorbent fluid storage components, without collapsing. These absorbent foams are made by polymerizing high internal phase emulsions (HIPEs).

  • Patent number: 5693187
    Abstract: An apparatus for making paper. The apparatus comprises a felt and a pattern layer joined to the felt. The felt has a relatively high UV absorbance. Such a high UV absorbance prevents the actinic radiation applied to cure the pattern layer from scattering when the radiation penetrates the surface of the pattern layer. By limiting the scattering of radiation beneath the surface of the pattern layer, extraneous cured pattern layer material is minimized in the regions of the felt where it is desired not to have pattern layer material.

  • Patent number: 5690790
    Abstract: The present invention relates to paper products having temporary wet strength. The paper products contain cellulosic fibers that are treated with a polyaldehyde polymer having free aldehyde groups and a water soluble polyhydroxy polymer. The initial wet strength obtained with the combined use of these materials is significantly greater than that obtained by use of either the polyaldehyde or pelyhydroxy polymer alone. At the same time, the wet strength decays at a rate that is rapid enough to enable the paper product to be flushed under conditions of normal use.
