  • Method of forming cardboard tampon applicators having a dome-shaped forward tip
    Patent number: 5290501
    Abstract: A method for forming a tampon applicator having a dome shape forward end, in which the stability of the petal tips to maintain their closure, is enhanced. During the manufacture of the tampon barrel, the petals which collectively form the dome shape tip are sprayed with a predetermined amount of moisture prior to their being presented to the heated tip forming die. It has been observed that the addition of moisture prior to petal tip formation counteracts the tendency of the petal tips to thereafter move towards their opened condition.
