Container for dyeing (TW1)

I'm looking for a contain of some kind to dye a pair of jeans.

Something around an 11 litre container if possible.
An old dog food container etc, or old pot or bucket.

As long as it doesn't leak I'll take it in any condition.

No rush either, if you only half way through a product but you have something suitable.

Thansk so much for reading.
