Abstract: Absorbent articles having a unique elastic feature improving the dynamic fit as well as containment characteristics. The elastic feature preferably comprises an elastomeric member and a segment of the backsheet; a portion of the backsheet segment coincides with at least a portion of the elastomeric member; this portion of the backsheet segment being mechanically prestrained. Mechanical prestraining of the backsheet segment improves not only the extension of the elastomeric member, but also the heat-shrink contraction of preferred elastomeric members.
Abstract: An absorbent article having a main body portion and a pair of flaps joined to the main body portion. The flaps are folded over the garment side of the main body portion such that the flap adhesives and the central pad adhesives can be covered by a single release liner. The flaps may or may not be used while the absorbent article is being used, i.e., the absorbent article may be used by wrapping the flaps around the edges of the crotch region and securing the flap adhesives to the underside of a user's panty; alternatively, the flaps may be left in their folded configuration on the garment side of the main body portion and the flap adhesives may be secured, along with the central pad adhesive, to the inner crotch region of the panty.

Abstract: Particulate, absorbent, polymeric compositions comprising interparticle crosslinked aggregates. The interparticle crosslinked aggregates comprise precursor particles of substantially water-insoluble, absorbent, hydrogel-forming, polymer material; and an interparticle crosslinking agent reacted with the polymer material of the precursor particles to form crosslink bonds between the precursor particles. Sufficient interparticle crosslinked aggregates are formed when the mass average particle size of the resultant polymeric composition has been increased by at least about 25% over the mass average particle size of the precursor particles. The resultant polymeric composition provides improved structural integrity, an increased acquisition rate, and minimal gel blocking properties.

Abstract: Lipids are removed from spent coffee grounds using certain lipophilic solvents or series of solvents. The resulting defatted spent coffee grounds contain less than about 2% lipids. The defatted spent coffee grounds act as an adsorbent for bitter coffee flavors and burnt coffee aromas. This adsorbent can be added to roast ground coffee, preferably low quality or dark roasted coffee, to reduce burnt aromas and bitter flavors associated with the corresponding brewed coffee or coffee extract.
Abstract: The present invention is directed to a single lamina tissue paper having visually discernible, large scale patterns made during the drying step of the papermaking process. Particularly, the tissue is made on a blow through drying belt having a pattern of alternating knuckles and deflection conduits. This pattern produces a like pattern of regions in the paper having alternating values of crepe frequencies, opacities and elevations. The differences in these values produces a visually discernible pattern.

Abstract: The present invention presents improved packages for single-use, disposable folded towels, and more particularly to single- and multi-towel packages which provide for readily grasping a defined portion of the towel upon opening the package and automatic unfolding of the towel upon removal from the package without a separate unfolding step requiring additional consumer action. Single-towel embodiments are disclosed which provide for complete unfolding of the towel by the use of: (a) an opening bearing a particular geometrical relationship to the dimensions of the folded towel; or (b) a flexible bar within the package to provide unfolding of the towel in the longitudinal direction. A multi-towel embodiment which provides for the advantageous dispensing features and convenience of an improved single-towel package while providing the added capability of multi-towel transportation is also disclosed.
Abstract: The present invention provides a combined package comprising a container and a mascara applicator. The applicator includes a hollow shaft having a longitudinal axis extending from the handle. A rod having a brush affixed at one end reciprocates within the hollow shaft. The rod has a first position and a second position such that when the handle of the applicator is secured to the container the rod reciprocates to the first position extending the hinge beyond the hollow shaft such that the brush is substantially non-aligned with the longitudinal axis of the hollow shaft. Upon removal of the applicator from the container the rod reciprocates to the second position causing the hinge to retract within the hollow shaft, thereby substantially aligning the brush with the longitudinal axis of the hollow shaft. This combined package allows the user to stir the product within the container when both attaching and removing the applicator to and from the container.

Abstract: A consumer product passage incorporating a mixing chamber for mixing air and liquid. Consumer packages of the present invention are capable of providing excellent spray qualities at typical consumer product flow rates (e.g., less than about 1.0 cubic centimeters per second) while simultaneously maintaining relatively low air to liquid ratios (e.g., less than about 0.06:1 on a mass basis) and relatively low pressures (e.g., less than about 50 psi). The package of the present invention also offers significant environmental and safety advantages. For example, it does not depend upon dissolved propellants; and it permits the use of water in place of volatile solvents as thinning agents since high surface tension fluids are actually sprayed better. Several packages of the present invention are illustrated, including a standard aerosol version, pump and spray versions, and a finger pump version.

Abstract: A disposable absorbent article, such as a sanitary napkin, is disclosed that has components which may separate in the Z-direction with relation to other components of the article when the absorbent article is worn. The sanitary napkin of the present invention comprises a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core positioned between the topsheet and the backsheet, and a liquid pervious spacing structure for moving the topsheet away from the core. The spacing structure is generally positioned between the topsheet and the core. The spacing structure has a longitudinal centerline, and opposed lateral sides which may move inwardly toward the longitudinal centerline when the spacing is compressed from the sides. This results in at least a portion of the spacing structure moving the topsheet apart from the absorbent core. In an alternative embodiment, the sanitary napkin of the present invention also has an absorbent core which separates from the backsheet of the sanitary napkin.
