Mine's not a snug fit either - it just rests on top - nothing evaporates.
Make sure you only use a very little liquid in it when cooking veg as they give off their own liquid and as none of it evaporates the dish can get very soupy if you use the usual amount of liquid.
Love mine - wouldn't be without it. Get lots of use out of it.
