Abstract: A dispensing cap for vacuum bottles including a cap body in the form of an inverted glass coupled to the nozzle of the vacuum bottle and having a liquid discharge axial opening, an annular gasket mounted at the upper part of the cap body around the liquid discharge axial opening and defining a concave-spherical surface portion, and a spout having an inlet end in the form of spherical surface portion constantly tightly seated against the annular gasket and an outlet end maintained in communication with the inlet end through an axial throughbore, the spout being tiltable around an axis orthogonal to the longitudinal axis of the vacuum bottle between a closed position in which the spherical surface portion of the inlet end seals the liquid discharge axial opening and an open position in which the outlet end is spaced away from the cap body and the inlet end maintains the axial throughbore in direct fluid communication with the liquid discharge axial opening.
