The vial is provided with screw threads on the outer portion of its neck, a V-shaped recess in the lip, and an upwardly facing, inclined, annular shoulder on the inner wall of the neck. The cap has a cylindrical outer skirt and a shorter, inwardly spaced, inner, cylindrical skirt adapted to be sealingly received against the annular shoulder provided in the wall of the container to make sealing abutment therewith. An annular bead is provided on the cap between the inner and outer skirts and is adapted to seat against the V-shaped recess provided in the lip of the container.
