Open the CIPO recordAbstract From the Canadian patent
Improvements Relating to Laundry Pressing Machines A laundry pressing machine has a flexible sheet (4) resting on a perforated frame (5). Articles (10) to be pressed are laid on the sheet (4) and a framework (2) is closed onto a supporting framework (1) so that the article (10) is overlaid with a further flexible sheet (6). Air is then withdrawn through an air vent pipe (8) to cause the article (10) to be gripped tightly between the sheets (4) and (6). Finally air or liquid preferably warmed, is pumped in through a pipe (9) to cause the sheets (4) and (6) to bow upwardly so that the article (10) is stretched to remove wrinkles.

Why it's free to use
- Filed December 8, 1989. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 8, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 8, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
