Practical swivel plate ashtray.

The stub is supported without pressing it, it turns the saucer… done: the stubble falls into the ashtray and closes the saucer to stop burning for lack of oxygen. This eliminates the bad smells of bad cigarettes in the traditional cargo holders.
For emptying, simply separate the golden part from the ashtray and then remove the stubs.

Ashtray in cardboard box.
