Why does a BIC lighter have separated fuel chambers?

I don’t know why it is there, but it has nothing to do with fuel usage, as it is the gas phase of butane in a lighter that escapes through the valve and burns.

Check the menu on the left for everything you ever needed to know about the Bic lighter. But…it doesn’t actually answer the question, so I’ll nth the structural thing and also suggest that it helps you get a few more smoke’s worth of juice out of the thing.

structural integrity yes, but more to the point it is likely to allow them to use less plastic in the body of the lighter and/or make it a less naturally strong shape, while maintaining structural integrity.

Just a side note from a design engineer (who doesn’t have a lighter to hand as he doesn’t smoke), it’s most likely structural integrity and by the way plastic is actually quite expensive per tonne, so it’s best to make parts strong through shape and not mass.
