Apparatus and method for determining residual seal force of sealed containers
摘要:
The invention is an apparatus and method for testing the residual seal force of the closure of a container, particularly a container for parenteral pharmaceutical products. An automated and instrumented press collects stress and strain data for a closure of a container for parenteral pharmaceutical products. An algorithm is automatically applied to the resulting data set, determining candidate residual seal forces for several data smoothing spans. Confidence levels are determined for each of the candidate residual seal forces. The candidate residual seal force corresponding to the highest confidence level is selected. The process is repeated and the results averaged to determine a final residual seal force.
