You see the liquid at the bottom of the bottle, you can’t get anymore out without taking the top off. as you can see there is still fair amount of liquid left available to use.

The current design of the bottle flows the liquid to the edges of the bottle away from the the pump mechanism. To be less wasteful, might we redesign the bottom of the bottle so the liquid flows to the center*1 allowing the pump mechanism to use more of the available liquid?
