A bottle cap torque tester is a measuring system that is required during the design process under the conditions of “storage, transportation, packaging and handling before usage“. The cap should be sufficiently closing the bottle to make sure the content is not running out of the packaging, and on the other hand, it should be easy to open. In the pharmaceutical industry, the opening and closing torque of bottles and other containers with twist-off closures is an important quality parameter. The lower torque limit is considered the minimum pressure of the cap to avoid any leak of the product. The higher torque limit is the maximum torque the customer can apply to open or close the product’s cap.
