ABSTRACT:
A break away overcap is used for maintaining a closure in sealing engagement with the open end of a vial. The overcap is molded from a fracturable plastic and is provided with a pair of spaced, parallel score lines or V-grooves extending across the top wall of the overcap and downwardly of the cap skirt to the lower edge thereof on each side of the cap. Thumb and finger engaging portions are provided at the lower edge of the skirt adjacent the terminal ends of the score lines so that by pushing inwardly on the thumb and finger engaging portions, the overcap breaks into three pieces to thereby expose the closure for insertion of a syringe needle therethrough into the vial for removal of the vial contents therefrom.
