Patent 11982593 was granted and assigned to West Pharmaceutical Services on May, 2024 by the United States Patent and Trademark Office.
Systems and methods for determining Container Closure Integrity (CCI) in a container system comprising a container, an elastomeric stopper, and a retainer for retaining the stopper in place are disclosed. The systems and methods involve disposing, within a seal assembly, a component configured to sense a degree of compression of the elastomeric stopper. In a first implementation, the elastomeric stopper comprises an embedded positioning component embedded within the elastomeric material. The position of the positioning component is sensed using a detection system and the integrity of the closure is determined based on the position of the embedded component. In a second implementation, a force sensitive resistor is disposed within the seal stack to measure the compression of the elastomeric stopper. The compression of the elastomeric stopper is correlated to the integrity of the seal.
