Open the CIPO recordAbstract From the Canadian patent
The packaging is an assembly composed of a substantially rigid outer shell and a inner shell in plastic material contained in this outer shell. The relative dimensions of the outer shell and of the inner shell are such that inner shell can be placed either in a first retracted position in which its base rests on the base of the outer shell and its spout is retracted in the outer shell or in a second extended position in which the inner shell is suspended in the outer shell and its spout goes beyond an opening provided in the cover of the outer shell. The inner shell can be displaced between these two positions according to requirements.

Why it's free to use
- Filed February 22, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 22, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 22, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
