In Europe a lot of liquid detergents are measured into a dosing device which, in the case of Unilever's Persil liquids is a small cap that's made out of a rubber-like substance.
You fill it to the mark, put it on top of the clothes and start the wash and it just bounces around fairly silently and dispenses the liquid so you don't have to measure anything or deal with drips while trying to empty a cap into the drawer.
Powders, dry tablets and softeners are almost always dispensed using the drawer.
