Open the CIPO recordAbstract From the Canadian patent
Mixing a controlled amount of agar with regular oral dental or skin hygiene compositions allows manufacture of homogenous semi-solid single-use lumps or beads (200). Agar or analogous structural gelling agents confer sufficient rigidity and a sufficiently high melting point for storage yet allow disruption of the bead on the skin or in the mouth without residues. Dental or skin care packs (600) hold sufficient beads and optionally a disposable brush. Blister packs (124) carry cast in-situ beads of one or a variety of active compositions. Shape colour and flavour variations (124C) motivate children towards dental care.

Why it's free to use
- Filed January 30, 2004 and granted April 8, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 30, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 30, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
