摘要： The invention is directed to an improvement of performance for disposable absorbent articles to prevent a leakage of body discharges. A disposable absorbent article comprising: an absorbent body having an average width of from about 5 mm to about 30 mm. The first resilient material is disposed between the body facing surface and the garment facing surface of the absorbent article; and a first resilient material disposed between the body facing surface and the absorbent body in a circumferential manner such that at least a part of the body facing surface of the absorbent article forms a raised circumferential bank in the central region and a concave portion surrounded by the raised circumferential bank. The first resilient material is selected from the group consisting of a polymeric foam material, a fibrous material, an elastic material, a formed film material, an absorbent gelling material, and a mixture thereof. In another aspect of the invention, a disposable absorbent article has the body facing surface having a shape which forms a raised circumferential bank in the central region and a concave portion surrounded by the raised circumferential bank. The raised circumferential bank has an inside wall and an outside wall. The outside wall of the raised circumferential bank has an average slope angle of from about 5 degrees to about 85 degrees or from about 95 degrees to about 175 degrees.
