Open the CIPO recordAbstract From the Canadian patent
Evaporation control for a fluid supply such as used in a clinical analyzer, can be provided by utilizing a straw-like insert (32) which is disposed into a fluid-containing bottle (20). The straw provides an increased diffusion length or "stagnant" zone. The bottle can also be configured to effectively reduce evaporation in a similar manner by providing a narrowed diameter prior to the fluid retaining portion of the bottle and by increasing the distance between the top of the bottle and the top of the fluid surface.

Why it's free to use
- Filed March 31, 2003 and granted February 1, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 31, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 31, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
