eli5: Why do cheap lighters have a divide in their fuel reserve?

302 views

I recently got a science teaching job and had to buy a cheap see-through lighter to ignite the Bunsens, I don’t understand why the tank has to have two different compartments on the inside. You can tilt it and fill up one or the other, could someone explain why this is necessary instead of one big tank?

I’m pretty sure the only reason is strength. Bic lighters also have a divided tank like the cheap crack lighters do.
