A Flip Off Seal, also known as a Flip-Off cap, is a type of closure used in pharmaceutical packaging, particularly for sealing vials containing liquid or lyophilized medications. It's a two-part closure, consisting of an aluminum seal and a plastic cap, designed to maintain sterility and integrity of the contents until the point of use. The plastic cap is designed to be flipped off, revealing a rubber stopper that can be penetrated by a syringe for medication withdrawal.
