TamperProof© Benefits

Machine Vision Company has developed a product to inspect and ensure the integrity of tamper-evident closures. TamperProof© verifies:

  • that the tamper seal is intact,
  • that the closure is not cocked
  • that the closure height, relative to a reference point on the container, is within tolerance indicating that the closure has been torqued correctly,
  • and verifies the closure color.

Tamper-evident plastic closures are used on many nutrition, beverage, and food containers. Tamper-evident closures provide a security measure to the manufacturer and a guarantee to the consumer that the container has not been opened and the contents have not been compromised.

MVC’s solution mounts over the conveyor and can inspect plastic product closures at a rate of up to 1000 closures per minute. Multiple cameras are positioned around the closure, providing 360 degree inspection. An inspection recipe management system is included and an optional height adjustment system is available, making changeover fast and easy.
