Abstract From the Canadian patent

Disclosed is a sanitary napkin and releasable wrapper package. The releasable wrapper is folded about the longitudinal side margins of the sanitary napkin in a C-fold so that both faces of the sanitary napkin are protected and a relatively smaller package is produced than if the releasable wrapper extends laterally beyond the longitudinal side margins of the sanitary napkin. The releasable wrapper and sanitary napkin may be trifolded about spaced-apart laterally oriented fold lines to produce a discrete single use package. Several variations including flapped and asymmetric embodiments are illustrated.

Why it's free to use

  • Filed May 23, 1991 and granted January 12, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 23, 2011.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 23, 2013.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
