Lists of all values of a two-variable function

Hi all,

I would like to do this: given a function _f_ in two variables and two
lists l1 and l2, to get the list of all values f[a,b] with _a_ in l1 and
_b_ in l2, with all duplicated values removed. How do I do that?

The closest thing that I am able to do is:

Table[f[l1[[i]],l2[[j]]],{i,1,Length[l1]},{j,1,Length[l2]}]

but, of course:

1) what I get is a list of lists;

2) I eventually get duplicated values.

Best regards,

Jose Carlos Santos
