Diaper having disposable chassis assembly and reuseable elasticized belt removably retained by said chassis assembly

A diaper article comprising:

• a disposable chassis assembly having a liquid-pervious body-side liner and a liquid-impervious barrier joined to one another about their peripheral edges and a liquid-absorbing core contained between the liner and barrier, the chassis assembly having continuous front, crotch and rear portions disposed along a central longitudinal axis, the core having a body face and a back face and containing a hydrogel concentrated toward the back face in at least the front portion of the chassis assembly, the core defining a generally rectangular shape having continuous front, crotch and rear portions disposed along the longitudinal axis with front and rear end margins each extending transversely to the axis;
• the chassis assembly having a pair of side margins each having forward, crotch and rearward areas which extend essentially parallel to the longitudinal axis outboard of the peripheral edges of the core and front and rear end margins extending transversely of the longitudinal axis, the crotch areas of the side margin being elasticized by a pair of gatherable leg cuffs;
• laterally aligned pairs of fenestrations formed at the forward and rearward areas of the side margins of the chassis assembly, respectively, the forward areas pair of fenestrations being longitudinally spaced below the front end margin of the core;
• and
• a reusable continuous elasticized belt adjustable in length which is separable from the chassis assembly, having an elongated central portion and a pair of free end portions which are engagable with one another, presenting cooperating mechanical closures, wherein the belt is adapted for being removably threaded through the forward and rearward areas pairs of fenestrations, engaging the central portion of the belt across the rear portion of the chassis assembly, and fastening the free end portions with one another across the front portion of the chassis assembly, providing a line of support extending across and below the rear end margin of the chassis assembly and the front end margin of the body of the core in the front portion of the chassis assembly corresponding to the lower abdominal region of a wearer, the belt being cinched across and below the front end margin of the core to securely position the chassis assembly against the wearer for absorbing discharged bodily wastes.

A diaper article comprising:

• disposable chassis assembly having a liquid-pervious body-facing liner and a liquid-impervious barrier joined to one another about their peripheral edges, and a liquid absorbent core contained between the liner and barrier, the chassis assembly having continuous front, crotch and rear portions disposed along a central longitudinal axis, the core defining a generally rectangular-shaped composite having continuous front, crotch and rear portions disposed along the longitudinal axis, and front and rear end margins each extending transversely to the longitudinal axis;
• the chassis assembly having a pair of side margins each having forward, crotch and rearward areas extending generally parallel to the longitudinal axis outboard of the peripheral edges of the core and front and rear end margins extending transversely of the longitudinal axis, the forward and rearward areas of the side margins of the chassis assembly each having laterally aligned pairs of fenestrations formed therein respectively, the forward pair of fenestrations being longitudinally spaced below the front end margin of the core;
• and
• a reusable continuous elasticized belt adjustable in length having an elongated central portion, and free end portions which are engagable with one another, the belt being removably threaded through the forward and rearward areas pairs of fenestrations engaging the central portion thereof across the rear portion of the chassis assembly and the free end portions with one another across the front portion of the chassis assembly, providing a line of support which extends across and below the rear end margin of the chassis assembly and the front end margin of the body of the core in the front portion of the chassis assembly corresponding to the lower abdominal region of a wearer, the belt being cinched across and below the front end margin of the core to securely position the chassis assembly for the absorbing of bodily wastes discharged in use.
