Abstract From the Canadian patent

A wet wipe container contains first and second protruding surfaces within the lid and base, respectively which contact each, other to maintain the lid in a partially open position until the user applies a sufficient downward force to close the lid. Maintaining the lid in a partially open position is particularly advantageous for users of baby wipes, who frequently have to reach into the container for a second wipe using only one hand.

Why it's free to use

  • Filed May 28, 1990 and granted January 11, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 28, 2010.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 28, 2012.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
