A two-piece seal vial assembly. The first piece is a vial defining an aperture adapted to contain a liquid. The vial has a base, a crown disposed opposite the base, and an upright side wall extending from the base to the crown and including a tapered inner diameter and a flange located proximate the crown. The second piece is a seal top defining an opening that runs through the length of the seal top. The seal top has a top portion providing a neck finish and, when the seal top and the vial are assembled, a snap groove releasably receiving the flange of the vial and a tapered portion that frictionally engages the tapered inner diameter of the vial. Although not one of the two main components of the assembly, a cap may be included to releasably engage the neck finish of the seal top to close the seal top.
