剂量药瓶 / Dose vials

This is a liquid medicine vial with design of quantitative outflow. Sometimes, we bought the liquid medicine, which will take only several milliliters each time. To design this type of dosage vials will make everything simpler. The tube has a scale on and a buckle clasp around. The buckle will be stuck in specific scale position to mark specific volume. The buckle can be snapped to the next scale by a little force. The volume of liquid, which is pressed out, is in accordance with the required scale on the tube exactly.
