Abstract
A sealed envelope contains a moistened pad that functions as a swab. The pad is secured to the envelope by an intermediate seal line. When the top of the envelope is removed, the pad is exposed. Since the pad is still captively held to the remainder of the envelope, the liquid on the pad may be dispensed by holding the clean, dry bottom of the envelope. The pad functions as a swab and the remainder of the envelope functions as the applicator handle and reservoir.
