fill (something) to (some point)
To insert or place something inside something else, but only to a certain stopping point. Often said of liquids. Well, no wonder she spilled her juice—you filled her cup all the way to the brim! Only fill the box up to here—otherwise, it will be too heavy to carry. I thought we were only supposed to fill the beaker to the 10 mL line.
