Component Specifications

Definition
A mechanical sealing component used in pharmaceutical vials that provides a tamper-evident closure system. It consists of a plastic or aluminum button that flips off when the vial is opened for the first time, indicating potential tampering and ensuring product integrity during storage and transport.
Working Principle
The flip-off button operates through a mechanical interlock with the vial's rubber stopper and aluminum cap. When the vial is sealed, the button is crimped in place. During opening, applying upward force breaks the tamper-evident band, allowing the button to flip off, which visually indicates the vial has been accessed.
Materials
Typically made from aluminum alloy (e.g., 1050, 1100 series) or medical-grade plastics (e.g., polypropylene, polyethylene). Materials must comply with USP <661> and USP <87>/<88> for biocompatibility.
Technical Parameters
  • Color Typically aluminum silver or colored for identification
  • Height 3-8 mm
  • Diameter 13-20 mm
  • Breaking Force 5-15 N
  • Sterilization Compatibility Autoclave, gamma irradiation, ETO
Standards
ISO 8362-1, ISO 8362-4, DIN 58366, USP <671>
