Child-resistant packaging or C-R packaging has special closures designed to reduce the risk of children ingesting dangerous items. This is often accomplished by the use of a special safety cap. It is required by regulation for prescription drugs, over-the-counter medications, pesticides, and household chemicals. Cap torque testing is performed for both conventional closures and child-resistant bottle caps. In case of liquids, 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 force the customer can apply to open or close the product’s cap.
