You might want to be careful not to shake the ex dropper bottle without the tip, it may leak. I seem to remember a problem of that kind. The extra height and surface may complete a (near) liquid tight seal on some blenders containers. I may have noticed increased flavor liquid caught in some caps without the tips after shaking. I don't have any unopened flavors at the moment to test my observations. It seems that, at the very least, a container with a drip tip when shaken will "leak" less
juice than one without.
