Open the CIPO recordAbstract From the Canadian patent
A method for forming a tampon applicator having a dome shaped forward end is disclosed, in which the requisite ejection force for discharging the pledget from the applicator is reduced by radially bending the petals forming the domed tip about their base prior to final fabrication of the dome-shaped petal tip. Several orders of the sequential steps for bending the petals are disclosed. The resultant tampon applicator has weakened fibers at the base of its petals to provide a desired significant reduction of the pledget ejection force.

Why it's free to use
- Filed May 3, 1993 and granted December 30, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 3, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 3, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
