Applicator swabs and method of making same
Abstract:
An applicator and/or scrub saturated with a desired fluid is packaged in a sealed, liquid-impervious pouch. The liquid-carrying applicator or scrub is made from open-cell, polyurethane foam. A cylinder of the foam is mounted on a stick. The tip end of the foam applicator is fastened to the tip of the stick in a manner that creates a rounded smooth tip. The tip end of the foam applicator may be formed into a smaller brush-like shape.
