Open the CIPO recordAbstract From the Canadian patent
A disposable diaper having elasticized crotch seals and an elasticized waist seal formed from elastic members secured to the backing sheet. The elastic members physically intersect each other and are under such tension so as to provide an initial stretching of the elastic members extending substantially at right angles to each other thereby maximizing the comfort of an infant wearing the disposable diaper while maintaining a boatlike shape before application on an infant with the ears in a raised position. The elastic members may be spaced from the edge of the pad or may overlie the front or back surface of the pad to minimize leakage.
