Open the CIPO recordAbstract From the Canadian patent
A container dome (12) with arch-like structures in elevation and polygonshaped structures in plan. The arch-like structures are provided by pairs of chordal stiffening facets (30, 30a) disposed in an endwise adjacent array extending transversely about the periphery of the dome (12) to enhance top loading capability. Each pair of facets (30 30a) has an inwardly-convex , chordal stiffening rib (36) which defines a regular transverse polygon having an uneven number of sides to prevent dome ovalization. Preferably multiple , vertically-stacked tiers (42 44) of facet pairs (30, 30a) arrays are utilized with each array being radially offset from adjacent tiers (42 44).

Why it's free to use
- Filed September 24, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 24, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 24, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
