"do anyone of you know the design by Rafael Marquina? It is considered for many people as the best in terms of functionality. I read he got inspired lab vessels. The bottle has a dispenser for a controlled an continuous pour just with one hand, and after serving the olive drops fall again into the bottle. Not a single drop on the outer side. THe patent expired quite a few years ago, and Rafael collected a lot of knockoffs, but some of them didn't work properly, something he joked about: "if you copy something, at least do it properly""
