How long will baked beans keep in the fridge?

[solidgoldbrass]

I have a big tin of baked beans. I don't want to eat the whole tinful (I am enough of a Windy Miller as it is) but I do want to eat some of them. If I pour the extra beans into a bowl (I know about not leaving them in the tin once opened), cover and put in the fridge, how quickly should they be used up?

they keep until they go mouldy or dry out.

why shouldn't they be kept in the tin btw?

Not in the tin because of rust, or something.
Baked beans last for ages. I ate some that were a week old, and they were fine. Loads of yummy healthy preservatives, probably

I think keeping them in the tin once its opened is a bad idea because of something to do with oxidisation and reactions between the metal of the tin and the beans when exposed to air. But thanks anyway.

the tin should tell you how long it is ok for once opened - normally 2-3 days I think.
