Abstract
An overcap assembly for a gear finish vial having a cap constructed and arranged to contain either a stopper-type closure or a sealing disc closure. A plurality of radially inwardly extending ribs are provided in the cap to maintain the closure in the cap and to cooperate with teeth on the gear finish to prevent turning of the cap assembly when in the sealing position on the vial. A plurality of inwardly extending tabs are provided on the lower end of the cap for selectively engaging shoulders on the vial neck for holding the overcap assembly upwardly from the neck of the vial in an unsealed position during the lyophilization procedure and downwardly on the neck of the vial when in the sealed position.
