Test to determine the superimposed compression / torsional forces on opening and closing of childproof containers or pharmaceutical packaging. For this a zwicki-Line tabletop testing machine of Fmax 2.5 kN and an additional torsion drive of 5 Nm torque are used. The two test axes can be used for independent or combined axial / torsion tests as required, the package being opened via a rotary movement with a superimposed axial loading. Important parameters are the opening torque required and the functioning of the childproof mechanism.
