Convenient Cavity is a shampoo bottle redesign that allows you to pump out the liquid with one hand. The cavity provides and easy grip plus doubles up as a spot to hang the bottle from. And because of the emptiness in between, the pump's pipe fits in the bottle at a slant, enabling you to extract all the liquid. Good for shampoo and any kinda liquid suds, if you ask me!

Convenient Cavity is a 2011 red dot design concept winner.
