  • Patent number: 7238175
    Abstract: A disposable diaper includes a basic absorbent batt structure and a supplementary absorbent batt structure placed thereon. An elastic member is provided between the two batt structures so as to transversely cross them. Contraction of the elastic member causes opposite side edge regions of the two batt structures to be pulled nearer to a longitudinal center line thereof. This results in a zone of the former batt structure underlying a distal end portion of the latter batt structure to curving downward with respect to a lower surface of the latter batt structure while the distal end portion of the latter batt structure curves upward with respect to a body facing surface of the basic absorbent batt structure. The curving of the batt structures forms a pocket opening from a front waist region toward a crotch region of the disposable diaper.

  • Patent number: 6540730
    Abstract: A brief assembly with a full front panel opening and an inner elasticized support panel includes two half width segments superposed in overlapping relationship, with a portion of the overlapped central area between rear portions of the segments bonded to form a unitary rear panel. The other half of the overlap is left unbonded to provide the full opening in the front panel. The outer margin of the opening can be reinforced by enclosure within a V-folded strip. Portions of outer side margins on each segment are removed to form an hourglass-shape. Overlapped segments are held together by a releasable fastener means that joins the two front panel half width segments. Tensioned elastic strands are attached to a support panel at spaced intervals. The support panel is secured to the inner surface of the overlapped segments. Tapes or other fasteners protrude from the side margins and are used to complete the waist and leg apertures after the front half is folded upward around a user's body.

  • Patent number: 6534694
    Abstract: A method of securing an elastic band between two material layers which are at least partially defined by meltable material includes forming perforations in the elastic band, placing the elastic band between two material layers, and bonding the material layers to one another through the perforations by heat fusion, wherein the perforations in the elastic band are formed at the same time as the material layers are fused together (i.e., the formation of the perforations in the elastic band is directly followed by bonding together, through the perforations, portions of the material layers). An elastic band secured between two material layers for inclusion in articles of one-time use includes the use of material layers that are at least partially defined by meltable material and an elastic band having perforations formed therein. The material layers are positioned on opposite sides of the elastic band and are joined together by heat fusion.

  • Patent number: 6483007
    Abstract: A sanitary napkin having an absorbent body and a layer of compressible and resilient, essentially non-absorbent material located adjacent a surface of the absorbent body which lies distal to a body of a water in use. The layer of compressible and resilient material has a surface area extending entirely over the surface of the absorbent body. Further, the layer of compressible and resilient material is thicker in a longitudinal central region of the napkin than in remainder of the napkin and the layer of compressible and resilient material is resiliently compressible in a direction perpendicular to the surface of the absorbent body, so as to urge the sanitary napkin to fill out all available space between the sanitary napkin and the body of the wearer during use.
