Abstract: A bottle is disclosed which comprises a neck that forms an upwardly extending mouth from and through which a liquid flows, and a first potion for preventing liquid residue from dripping upon the outer surface of the neck. The first portion includes at least one annular groove formed integrally with the outer surface of the neck near the mouth. The groove is defined by a frustoconical portion of the surface, coaxial to a central axis of the neck and having a diameter that decreases in a generally downward direction. It is also defined by an annulus-shaped portion, lying on a plane substantially normal to the axis and relatively smoothly filleted with the frustonconical portion. The maximum diameter of the annulus-shaped portion is substantially equal to the maximum diameter of the frustoconical portion.
