Abstract
Abstract This invention teaches a single-use, rectangular area, disposable diaper, having multiple longitudinal, parallel pleats disposed in accordion-type folds in the area, said folds being positioned on a baby''s torso parallel to the baby''s legs. The accordion pleated folds of this diaper simplify the placement of the diaper in the baby''s crotch in a position most suitable for maximum absorption and retention of the baby''s waste products.
