US Patent 7648299 Writing implement with a cap that can be screwed on

A writing implement includes a shaft part that holds a stylus and a cap, which can be screwed onto the shaft part in order to cover the stylus from an initial position of engagement up to a final position. A resistance against the screwing on, which is greater than the resistance when screwing on from the initial position of engagement up to an intermediate position, acts upon the cap when screwing on the cap from the intermediate position, which is located between the initial position of engagement and the final position, until reaching the final position.
