Abstract
An absorbent article is provided that is comfortable and suitable for absorbing and containing liquid and solid body exudates without leakage. The absorbent article may be a diaper that includes a backsheet layer, a substantially liquid-permeable liner layer, and an absorbent core located between the backsheet and the liner. The backsheet generally defines a front waistband section, a rear waistband section, and an intermediate section, with the intermediate section interconnecting the front and rear waistband sections and disposed between laterally opposed side margins. The backsheet layer has at least one pleat adjacent each side margin that defines an expanded volume when the pleat expands, the expanded volume being greater than the volume when the pleat is unexpanded. The pleat is accessible to body exudates that pass through or around the absorbent core.
