  • Tampon applicator
    Patent number: 9339419
    Abstract: In a tampon applicator, an elongated barrel has an interior chamber for housing a tampon therein, a grip region generally adjacent an outer end of the barrel, a tip region generally adjacent an inner end of the barrel, and a central region extending longitudinally between the grip region and the tip region. A plunger extends into the barrel at the outer end thereof and is moveable relative to the barrel to expel the tampon from the barrel at its inner end. The outer surface of the barrel at the grip region has a different coefficient of friction than at the central region of the barrel. In other embodiments the coefficient of friction of the barrel outer surface at the central region is different from the coefficient of friction at the tip region.
