ancient lighters?

In alot of ancient series, I see people use a device to light objects. They take the cap off, blow into it, and the cherry becomes red. How do those work?

TV magic. Someone on the camera crew has a Zippo. Although, China did have some ancient matches. I don't think that cap thing is real but I wouldn't mind being pleasantly surprised.
