Towards the bottom, the lid has a stop against the pot. This is a "half form-fit" because upwards it can be removed. A form-fit acts via the geometric contact of two effective surfaces, and the effective forces are transmitted as normal forces to the effective surfaces of a driver part (surface pressure and Hertzian contact stress). Typically ...
Polypropylene lid of a Tic Tac box, with a living hinge and the resin identification code under its flap. As polypropylene is resistant to fatigue, most plastic living hinges, such as those on flip-top bottles, are made from this material. However, it is important to ensure that chain molecules are oriented across the hinge to maximise strength.
