The US Consumer Product Safety Commission (USCPSC) has made many recalls over the past several years due to either faulty or improperly functioning child-resistant caps. The USCPSC has the jurisdiction to recall packages that do not comply with the Poison Prevention Packaging Act (1970).
One eye care product manufacturer recently contacted Mesa Labs requesting a unit that could help them determining which CR closure would be most effective for their manufacturing process. Their interest was initiated by warnings from the FDA and the USCPSC about poisonings that have occurred due to improperly functioning child-resistant cap/bottle combinations.
For child-resistant cap designs, a topload force must be applied in order to operate the cap, making it difficult for children to open the caps. For many years after the introduction of the first child-resistant caps, it was sufficient to apply an initial topload that engaged the outer shell with the inner cap. As time has passed, new child-resistant cap designs have emerged requiring a topload to be applied continuously, not just in the beginning of the test.
With the topload chuck it is possible to adjust the topload force by changing the distance between the chuck and the platform. The plunger applying an initial topload was not sufficient for certain child-resistant designs which lead to the development of the topload chuck, available for all SureTorque units.
