Abstract: A hand operable calibration device for calibrating or re-calibrating a spring type torque tester, the device having first and second partially overlapping members with bearings therebetween to permit relative rotation between the first and second members. The first and second members are provided, respectively, with first and second annular permanent magnets which are spaced apart and which overlap one another to create a magnetic drag of reproducible magnitude against the relative rotation between the first and second members. One of the members is grasped by the jaws of the torque tester that is being calibrated or re-calibrated, a torque is applied to the other member to overcome the magnetic drag against the relative rotation between the members and the level of torque needed to cause relative rotation between the first and second members is compared to the torque reading indicated by the torque tester at the time such relative rotation begins.

Abstract: A tamper indicating package comprising a container having a neck with external threads formed thereon, and a plastic closure comprising a top panel and an integral depending annular skirt. The skirt has integral internal threads thereon complementary to the threads on the neck of the container. The container having an annular bead positioned axially below the threads. The skirt has a tamper indicating ring at the lower end thereof connected to the remainder of the skirt along a weakened line below the threads when the closure is on the container. The band has a radially inwardly extending lug on the inside surface thereof such that when the closure is threaded on the container, the lug falls into the notch and engages the underside of the annular bead and when the closure is rotated to unthread the closure, the lug is cammed downwardly under the bead and at least a portion of the band is severed from the remainder of the closure.
