A container for holding a liquid has a vessel that is open at the top and has an externally threaded neck through which liquid may be poured. A cap that has an internally threaded neck through which liquid may be poured screws onto the vessel. The cap can be inverted and a measured amount of liquid can be poured from the vessel into the cap. The cap can be transparent or translucent and can marked to indicate the amount of liquid it holds. An annular lip on the inside of the cap above its internal threads is sloped on top and flat on the bottom. Any liquid remaining in the cap flows down the sides of the cap, over the annular lip, and drips into the vessel, thereby preventing the liquid from flowing in between the threads and down the sides of the vessel. The top of the vessel may be sealed with a heat seal. When the heat seal has been removed it can be replaced on top of the vessel and the flat bottom of the annular lip will press against it to prevent liquid from leaving the vessel.
