ABSTRACT:
A closure structure for a two-compartment vial or container wherein a lyophilized medication is contained in one compartment and a solvent is contained in the other compartment. A displaceable, moisture-proof plug is removably disposed within a constriction between the two compartments. The closure structure includes a stopper which is partially inserted into the neck of the vial and a cap having a portion for fastening the cap to the vial neck. The cap has a cup portion of reduced diameter which snugly surrounds the protruding portion of the stopper and is disconnectible from the fastening portion in order to move with the protruding portion of the stopper into the neck of the vial under manually applied pressure. The cup portion is then removed so that the needle of a syringe can be inserted through the stopper to communicate with the interior of the vial.
