A child-resistant cap rests on a mechanical paradox: it must resist a child under 52 months while remaining easy to open for a senior adult. This trade-off plays out in a two-step mechanism whose compliance cannot be verified with a simple torque measurement. Two...
On a tamper-evident cap (with a tamper-evident ring), opening the cap generates two successive torque peaks: the torque required to break the ring, followed by the torque required to rotate the cap. Virtually all the relationship meters on the market measure just one....
Cap torque testing standards define how manufacturers should measure and control this critical parameter. In the packaging industry, the tightening torque of a cap is one of the most critical quality parameters—and yet one of the most overlooked. A cap that is not...
In the industrial, automotive and research sectors, precision is paramount. When assembling components with screws or bolts, it’s essential to control the force applied. This is where an often overlooked but indispensable tool comes into play: the torquemeter....
