Open the CIPO recordAbstract From the Canadian patent
A reusable packaging system has a plastic container for receiving objects. The container (1) consists of separable elements (2,3), such as tray-like base and top elements (2) and wall frame elements (3), constituting module elements in a modular system. The module elements (2,3) have an element-compatible interface configuration at their periphery such that different module elements of the system, and in particular also elements external to the module system defined according to form, size and design of the individual modules, may only be joined to other module elements via the compatible interface configuration.

Why it's free to use
- Filed March 7, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 7, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 7, 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.
