Open the CIPO recordAbstract From the Canadian patent
An improved washable diaper is provided with an absorbent liner that is folded within the diaper during use for improved absorbency and, following use extends from the diaper, for improved efficiency of cleaning and drying. An additional liner may be secured to the liner in cases where extra absorbency is required, such as for overnight use and removed, from the liner for cleaning and drying. The liners provide additional layers of absorbent cloth while their separation from the diaper body following use avoids the difficulties of cleaning and drying presented by a number of cloth layers permanently secured to one another.

Why it's free to use
- Filed February 2, 1990 and granted August 18, 1992. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 2, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 2, 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.
