Box for containing sand (or hygienic litter or other material for receiving the excrements of animals) which can be used as toilet by the cat and which is realized in disposable execution, i.e.: that after the use it is destinated to the trash. Realized in two types: full toilet-box (it already contains the sand) and empty toilet-box (it must be filled with sand). Both types have been devised in two versions: as self-standing disposable toilet-box or as spare disposable toilet-box for being received by another structure.

Why it's free to use
- Filed July 30, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 30, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 30, 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.
