A disposable absorbent undergarment is disclosed. It includes an absorbent assembly comprising a core formed of a synthetic tow or of synthetic nonwoven layers and having first section comprising a slow acting but high absorption capacity SAP and a second section comprising a fast acting but lower absorption capacity SAP, all of which is wrapped in a wrapper to hold the SAP in place. The absorbent assembly may be quilted and corrugated. The undergarment also includes releasably securable fasteners to enable it to be readily removed and a suspension system to ensure that the garment fits properly and doesn't leak even when holding a large amount of exudate. Odor removal/masking and treatment features may be provided. It addition the undergarment may include a wetness indicator.
An absorbent assembly for use in a product to be worn by a living being for absorbing and retaining exudates from the being therein, said absorbent assembly comprising a core formed of a plurality of fibers or nonwoven separation layers or combinations thereof having a multitude of interstitial spaces between said fibers or nonwoven layers, said core having a first section and a second section, said first section comprising at least a plurality of a slow acting but high absorption capacity SAP in fluid communication with said interstitial spaces and/or said nonwoven separation layers of said first section of said core, said second section comprising at least a plurality of a fast acting but lower absorption capacity SAP in fluid communication said interstitial spaces and/or said nonwoven separation layers of said second section of said core, said first section of said core and said second section of said core being in fluid communication with each other, said absorbent assembly being arranged to be worn by the living being, with said first section of said core forming a body-facing side disposed confronting the perineum region of the being and said second section of said core forming a remote side disposed away from the perineum region of the being, whereupon fluid voided by said being flows to said fast acting SAP and to said slow acting SAP, wherein said fluid is absorbed quickly and rapidly by said fast acting SAP, while said slow acting SAP desorbs or takes fluid away from said fast acting SAP as well as absorbing said fluid itself.
A disposable absorbent undergarment comprising a chassis, an absorbent core, and a suspension system, said chassis comprising a sheet of a cloth-like, non-woven, breathable material, said sheet having a front section, a back section, and an intermediate section, said front section including a top front edge and pair of front side edges, said back section including a top back edge and pair of back side edges, said intermediate section including a pair of central side edges, each of which is an ergonomically shaped recess to form a respective leg opening for the brief, said absorbent core being located on said sheet at said intermediate section, said suspension system comprising plural elastic sections, each of said elastic sections comprising a apex end and a terminus end disposed generally opposite to said apex end, the width of said terminus end being substantially greater than the width of said apex end, said elastic sections being stretchable between said apex end and said terminus end, with the stretching force when said section is stretched being concentrated at said apex end and spread out along the width of said terminus end, a first of said elastic sections being secured to said sheet with said apex end of said first section being located at the recess in a first side edge of said sheet and with said terminus end of said first section terminating adjacent the top front edge of said sheet adjacent said first side edge, a second of said elastic sections being secured to said sheet with said apex end of said second section being located at the recess in a second side edge of said sheet and with said terminus end of said second section terminating adjacent the top front edge of said sheet adjacent said second side edge, a third of said elastic sections being secured to said sheet with said apex end of said third section being located at the recess in said first side edge of said sheet and with said terminus end of said third section terminating adjacent the back top edge of said sheet adjacent said first side edge, and a fourth of said elastic sections being secured to said sheet with said apex end of said fourth section being located at said recess in said second side edge of said sheet and with said terminus end portion of said fourth section terminating adjacent the top back edge of said sheet adjacent said second side edge, whereupon said suspension system pulls up on said chassis from said leg openings toward said top ends when said undergarment is worn.
A disposable absorbent undergarment comprising a chassis, an absorbent core, and a releasably securable fastening system, said chassis comprising a sheet of a cloth-like, non-woven, breathable material, said sheet having a front section, a back section, and an intermediate section, said front section including a top front edge and pair of front side edges, said back section including a top back edge and pair of back side edges, said intermediate section including a pair of central side edges, each of which is an ergonomically shaped recess to form a respective leg opening for the undergarment, said absorbent core being located on said chassis at said intermediate section, said releasably securable fastening system comprising a cohesive coating located on said front side edges and a cohesive coating located on said back side edges, said cohesive coating on said front side edges being arranged to be releasably secured to said cohesive coating on said back side edges.
A disposable absorbent undergarment comprising a chassis and an absorbent core, said chassis comprising a sheet of a cloth-like, non-woven, breathable material, said sheet having a front section, a back section, and an intermediate section, said front section including a top front edge and pair of front side edges, said back section including a top back edge and pair of back side edges, respective ones of said front side edges being secured to respective ones of said back side edges, and with said intermediate section including a pair of central side edges, each of which is an ergonomically shaped recess to form a respective leg opening, said absorbent core being located on said chassis at said intermediate section, said top front edge and said top back edge being secured to each other along a seal line extending slightly below said top front edge and said top back edge to provide a finger grasping region above said seal line to enable a person to grasp said top front edge and said top back edge to break the securement of the secured side edges.
