A system for packaging and dispensing liquid includes a glass vial, a metering pump and an assembly element. The vial, which defines a volume for receiving and containing the liquid, has a body, neck and tip. The neck and tip are joined at a line of weakness, and the vial is opened by snap-off removal of the tip at the weakness. The metering pump has a tubular body with a dip tube projecting downward, and a push-button dispensing head with a piston disposed for movement within the pump body, with a hollow rod defining an ejection duct projecting upwards. The pump body defines a vent closed by the piston at rest, and, in a mid-region, defines a shoulder for supporting engagement upon a lip of the vial neck. The assembly element, disposed for sealing engagement between the pump and vial, includes an elastically deformable sleeve fixed in sealed engagement upon a top portion of the pump body by a waist-band, with a skirt extending from the waist-band into sealing engagement against an exterior wall surface of the vial.
