Open the CIPO recordAbstract From the Canadian patent
A mechanism for removing a cork from a champagne bottle, wherein a manual force is applied along the bottle axis, so as to avoid side thrust forces that might cause the bottle to slip out of the person's hand. A lazy tong linkage is utilized to apply a magnified force onto the undersurface of the cork, whereby the person is able to exert a smooth controlled manual force on the mechanism as, opposed to a massive abrupt force that might tend to cause the bottle to drop or tip over.

- Filed October 6, 1989. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 6, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 6, 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.
