Abstract

Absorbent articles ( 30 ) have bonded materials and bond patterns. One of the absorbent articles ( 30 ) has a bond pattern ( 150 a - 150 d ) comprising bonds ( 151,153,155,155 a - 155 d ). The bond pattern ( 150 a - 150 d ) comprises a longitudinally extending series of bonds ( 151,153 ), which comprises a first bond ( 151 ) and a second bond ( 153 ) disposed longitudinally adjacent to the first bond ( 151 ). The first bond ( 151 ) has an inboard lateral edge ( 158 ), an outboard lateral edge ( 156 ), a top edge ( 152 ), and a bottom edge ( 154 ) having a recess portion ( 164 ). The second bond ( 153 ) has an inboard lateral edge ( 158 ) and an outboard lateral edge ( 156 ), a top edge ( 152 ) having a recess portion ( 164 ), and a bottom edge ( 154 ). The top edge ( 152 ) of the second bond ( 153 ) faces the bottom edge ( 154 ) of the first bond ( 151 ), each of the recess portion ( 164 ) of the first bond ( 151 ) and the recess portion ( 164 ) of the second bond ( 153 ) comprises terminal portions ( 157 ) which are disposed proximate the same outboard lateral edge ( 156 ) or inboard lateral edge ( 158 ) of the first bond ( 151 ) and the second bond ( 153 ). Such bond patterns ( 150 a - 150 d ) have been found to provide a superior combination of strength and softness.
