Upstanding Side Flap Patents (Class 604/385.28)
  • Patent number: 6346162
    Abstract: The invention relates to methods of fabricating an absorbent article. In one method of the invention, combination containment flaps and leg cuffs are formed on a common substrate. A plurality of elastomeric elements are included in the combination article to assist in forming containment flaps. Discrete leg cuff pieces are applied to the substrate at longitudinally spaced locations. In some embodiments, a cutting device slits the substrate substantially along a center line extending the length of the substrate, forming two continuous substrate portions. A glue gun applies adhesive to the substrate portion. The substrate portions are folded lengthwise, using the adhesive to form integral containment flaps and leg cuffs in a composite substrate. The composite substrate is secured to an absorbent article web sausage in forming absorbent articles. In another embodiment, the substrate is a first substrate which supports elastomeric elements used in forming leg cuffs and containment flaps.

    Abstract: The present invention relates to a sanitary absorbent article such as a sanitary napkin that has the ability to protect the undergarment of the wearer from being soiled by menstrual liquid. The sanitary napkin has a main body with panels that originate from its longitudinal side edges. A distal end of each panel that is continuous with the respective longitudinal side edge is folded underneath and affixed to the barrier later of the main body to form a looping member and a freely extending flap. As a result the effective affixation point of each flap is located inwardly of the respective side edge of the main body.

    Abstract: Disclosed in an absorbent article including a main body and leakage preventing walls. The leakage preventing walls extend longitudinally and lie opposite one another transversely. Each wall is formed of a nonwoven fabric having corrugations, the crests and valleys of which alternate with each other in the longitudinal direction. The nonwoven fabric is provided with an elastic member extending in the longitudinal direction for exhibiting longitudinal shrinking force. The elastic member is adhered to the valleys of the corrugations of the nonwoven fabric with an adhesive. The adhesive is applied to the surface of the elastic member in a band or linear shape continuous in the axial direction of the elastic member and appears regularly or at random at an interval on an arbitrary line which is set on the surface of the elastic member to extend parallel to the axial direction.
