US Patent 9198806 Containment pant

A permanently closed containment pant includes an elastically extensible chassis and a sling positioned within the chassis. The sling is joined to the front waist region and the back waist region. The sling includes a fluid-impervious base sheet and a containment flap joined with the base sheet to create a fluid-impervious pouch. The sling also includes a first transition and a second transition that are elastically extensible in a longitudinal direction and in a transverse direction. Material properties of the pouch and chassis provide the proper fit for comfort and leakage protection.
