Quantitative Bottle / medicine bottle

The Quantitative Medicine Bottle allows the users to take a fixed amount of liquid medicine each time. A small container with a gap at the brim is added at the bottleneck. When you need to take the medicine, just turn the bottle around, and the liquid will flow into the added container from the gap. When the container is filled up, you can turn the bottle around again and pour the liquid out from the container at the other side of the gap. This design saves us the time and energy of measuring the liquid as we often need to take a certain amount of medicine.
