A glass bottle comprises a neck (2) forming an upwards mouth (3) through which the liquid flows out and, for preventing liquid residues from dripping on the outer surface of the neck (2), at least one annular groove (4) integrally formed in the outer surface of said neck (2) nearby said mouth (3). Such groove is formed by a frustoconical portion (5), coaxial to the central axis (X) of the neck (2) and having a diameter which decreases downwards, and by an annulus-shaped portion (6), lying on a plane which is substantially normal to the axis (X) of the neck and smoothly filleted with said frustoconical portion (5), the maximum diameter of the annulus-shaped (6) portion being substantially equal to the maximum diameter of the frustoconical portion (5).
