Flip-Off Button Component – Chemical Manufacturing

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>

Frequently Asked Questions

What is the primary function of a flip-off button in pharmaceutical vials?

The primary function is to provide tamper-evident protection, visually indicating if a vial has been opened or compromised, ensuring drug safety and integrity.

Can flip-off buttons be reused after removal?

No, flip-off buttons are designed for single use. Once removed, they cannot be reattached securely, maintaining the tamper-evident feature.

What materials are commonly used for flip-off buttons?

Common materials include aluminum alloys and medical-grade plastics like polypropylene, chosen for sterility, durability, and compliance with pharmaceutical standards.
