Open the CIPO recordAbstract From the Canadian patent
A combination splash/trickle pack for an evaporative cooler, which comprises packing elements 10,12 made from expanded metal or plastics sheets. The packing elements 10,12 are arranged such that in use they form a stack of packing elements within the cooler with the width and length of the packing elements determining the width and depth of the pack. Each of a plurality of the elements 10,12 has an inclined surface with an angle of inclination which varies so that in use a first region of the surface is sufficiently inclined to the horizontal to serve as a trickle surface and a second region of the surface is sufficiently close to the horizontal to serve as a splash surface.

Why it's free to use
- Filed May 30, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 30, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 30, 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.
