Abstract
Abstract A tampon applicator includes a tubular barrel adapted to house a tampon therein and accommodate a slidable, tubular plunger which is adapted to push the tampon within the barrel out of the forward end of the barrel into a vagina. The barrel includes a rear portion having two diametrically opposed, substantially flattened surfaces with gripping ribs thereon and an angled transitional shoulder which has a reduced diameter relative to the front portion of the barrel. The flattened surface and the angled shoulder form a thumb and finger hold which enables a user to securely and comfortably maneuver and position the applicator and tampon therein.
