None really, the bottom of the sprayer has 5 depressed "wells" like the bottom of a 2L pop bottle, the straw to the injector hose sits in one of those depressions, once the liquid gets low enough, you just tip the bottle to the side that the pick-up straw is on...
Also, there's no cross contamination since you're not putting a needle into raw meat and back into the injection liquid to fill, any juice left over in the sprayer bottle can be saved for something else or another time.
