ABSTRACT:
An improved siphon dispenser has a hollow body divided into measuring and liquid receiving chambers by a partial partition. A lower neck portion has an air supply tube and a liquid supply tube. An elongated pouring spout is mounted through the body with the inner end positioned within a siphon tube mounted to the partition. A plurality of different length spouts having shoulders intermediate their length provides for accurate releasable mounting in the body via a boss integral to the body and a cap which has threads or, alternatively, a snap fit connection. The air supply tube has a restricted aperture for inhibiting liquid flow while allowing free flow of air. One restricted aperture includes an hourglass-shaped orifice with smooth upper and lower surfaces to minimize draining liquid adhering thereto. Another employs a ball-in-cage affixed to the lower end of the air tube with a lateral aperture above the cage that allows for air flow when in a pouring condition. The ball thus blocks liquid passage by sealing the large lower air tube opening to inhibit liquid flow therethrough. To provide for adequate liquid drainage the lower ball stop is formed by a plurality of spaced triangular-shaped inwardly directed protrusions with small apexes to minimize the surface area contact with the ball.
