ABSTRACT:
A self-contained apparatus for measuring threaded closure application torque that includes a container-shaped enclosure having a threaded finish portion configured to receive a threaded closure. A sensor is disposed within the enclosure and operatively coupled to the threaded finish portion thereof for supplying an electrical signal as a function of torque applied to the finish portion. Electronic circuitry within the enclosure is responsive to such signal for indicating torque applied to the threaded finish portion of the enclosure as a closure is threaded thereon. In use, the apparatus is inserted among containers being fed in succession through a closure application system, such that a closure is applied by the system to the threaded finish portion of the apparatus. The apparatus is thereafter removed from among the containers following application of closures to the apparatus and containers, and closure application torque is determined as a function of electrical signals stored within the apparatus.
