Abstract
The present invention is a sanitary napkin, or similar article such as a diaper, which has a flexible, moisture impervious barrier which can also serve as an envelope for maintaining cleanliness of the pad prior to use and/or for discreet and sanitary disposal after use. The barrier comprises a longitudinal envelope having one open edge. This edge has a flap which is normally turned inside the envelope and retained there by one or more areas of pressure sensitive adhesive while the article is in use. The flap can be withdrawn and, while grasping the pad only at the ends, the envelope can be turned inside out to protect the pad or prepare it for disposal. The flap is then pressed down and held by the areas of pressure sensitive adhesive to complete the package.
