A funnel which you can permanently screw on a 5l canister. Funnel also have a lid so you never have to put original lid back.

I tested 3 types of canisters and it fits perfectly.

I use it for used frying oil, but can be used for many different pusposes.

0,3mm tolerance on the lid - fits nicely, but you can use WD40 to decrease friction
