A container for an epoxy resin and a hardener comprises a flexible plastics tube (2) provided with an injection moulded screw cap (4). A spatula (8) formed integrally with the cap (4) and received in the tube (2) separates the tube into two compartments (10, 12), one for each of the epoxy resin and the hardener. When the cap (4) is unscrewed the spatula (8) rotates within the tube (2), mixing the epoxy resin and the hardener. The spatula (8) may then be used to apply the adhesive.

Why it's free to use
- Filed August 5, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 5, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 5, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
