A cap having a flat horizontal disc having first and second openings disposed in spaced apart positions therein. The first opening is a pin hole. The second opening is rectangularly shaped and has a direction of elongation. The disc has a peripheral socket adapted to engage the periphery of the upper end of the container in such manner that liquid cannot flow out therebetween. A hollow vertical hollow spout extends upwardly from the disc with a horizontal open lower end of rectangular shape extending in said direction and coincident with said second opening. A horizontal upper open end of of the spout has a rectangular shape extending in the direction. The lower and upper ends are essentially equal in area. An inner wall of the spout extends between and isconnected to the open upper and lower ends. A flat horizontal member is disposed in and is peripherally sealed to the inner wall in a position intermediate the upper and lower ends. The member has a rectangular opening therein which extends in said direction, the area of the opening being much smaller than the area of either one of the upper and lower openings.
