Abstract:
1. An infant or adult diaper having a longitudinal centerline and a lateral centerline perpendicular to the longitudinal centerline, wherein the diaper comprises a topsheet and a backsheet and positioned therein between an absorbent core, and a first and second longitudinally extending opposing elastic cuffs, positioned on either longitudinal side of the topsheet, the diaper having a crotch region, positioned in between a front region and a back region, wherein the diaper comprises a transverse separator sheet made of a separator sheet material, the transverse separator sheet having a transversely extending top edge and top edge portion and an opposing transversely extending bottom edge and bottom edge portion, and parts of the top edge portion being attached to the cuffs in the crotch region or front region of the diaper thereof by means of attaching a first attachment area of the top edge portion to the first cuff in the crotch region or front region of the diaper and a second opposing attachment area of the top edge portion to the second cuff in the crotch region or front region of the diaper, to form a first cuff attachment area and a second cuff attachment area, each cuff attachment area having an inner edge towards the longitudinal centerline of the diaper; and part(s) or all of the bottom edge portion being attached to the topsheet with one or more topsheet attachment area(s), wherein the first cuff attachment area has a first projected bond length as measured according to the projected bond measurement test method and the second cuff attachment area has a second projected bond length as measured according to the projected bond measurement test method, wherein: a) the minimum longitudinal dimension between the first projected bond length and the one or more topsheet attachment area(s) measured in flat state of the diaper is lower than the minimum longitudinal dimension between the first projected bond length and the one or more topsheet attachment area(s) measured in relaxed state of the separator sheet material when the separator sheet material is laid out flat onto an even horizontal surface and/or b) the minimum longitudinal dimension between the second projected bond length and the one or more topsheet attachment area(s) measured in flat state of the diaper is lower than the minimum longitudinal dimension between the second projected bond length and the one or more topsheet attachment area(s) measured in relaxed state of the separator sheet material when the separator sheet material is laid out flat onto an even horizontal surface.
