ABSTRACT:
An oral liquid dose vial and seal combination is disclosed which requires no crimping or other tools for assembly. A graduated vial of the combination has a circumferential external lip substantially adjacent to its mouth. A unitary plastic seal for the vial has a base plate and an endless rib protruding from the base plate. The rib is configured to fit into the mouth of the vial and to sealingly engage interior walls of the vial. A lip rims the circumference of the base plate and includes inwardly protruding ribs which engage the lip of the vial. A grippable tab is attached to the lip of the seal. Portions of the lip of the vial have thin walls so as to be frangible and to break when the tab is pulled upwardly with a force exceeding a predetermined threshold level. When the frangible portions of the lip of the vial break, the lip partially separates from the base plate, and the entire seal is pulled off the vial by the upwardly directed force.
