Open the CIPO recordAbstract From the Canadian patent
Tissue cartons containing a clip of interleaved tissues and featuring a plastic "pop-up" dispensing window having a slit through which the tissues are withdrawn can suffer from a tendency to dispense more than one tissue at a time. Multiple dispensing can be reduced substantially by providing the dispensing slit with "hooked" ends which hook away from the dispensing slit in opposite directions. The hooked ends provide sufficient added resistance to removal of the tissues so that the next-in-line tissue(s) is (are) less likely to be removed with the previous tissue in the clip.

Why it's free to use
- Filed May 13, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 13, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 13, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
