AI Technical Summary

Technical Problem

Existing positive control systems for container enclosed integrity (CCI) testing are complex and destructive, difficult to represent the container to be tested, and require complex setups.

Method used

A positive control system including a container and an adapter is designed, the container having a hollow interior and an opening, the adapter is equipped with a first and second coupling structure, the second coupling structure is vacuum sealedly connected to the edge of the container, and the first coupling structure of the adapter is connected to the flow reducing retainer, allowing the interior of the container to be approached to the flow reducing device.

Benefits of technology

Achieve high-quality and reliable CCI testing, allowing reused parts, maintaining original volume and leakage, is suitable for a variety of testing methods, avoiding the need for container prosthesis, and simplifying testing setup.

Abstract

The present invention claims a positive control system (1) for a container closure integrity (CCI) test, comprising a container and an adapter. The container (3) has a hollow interior (31), an opening (35) and a rim (331) surrounding the opening (35). The adapter (2) has a first coupling structure (21) configured to be connected to a flow reduction retainer (4) and a second coupling structure (22). The second coupling structure (22) of the adapter (2) is glued to the edge (331) of the container (3) in a vacuum-tight manner. The adapter (2) is configured such that the interior (31) of the container (3) is accessible from the first coupling structure (21).
