Coster has recently developed Rotor, a new 34mm diameter actuator with a twisting closure ring locking mechanism. The closure ring has two knurled areas for an ergonomic use of the ring, denoted by a "click".

The button is lower than the twisting ring to avoid accidental actuation and to ensure high resistance to top loads. The actuator is fixed on the mounting cup of the valve, designed for use  with several dimensions of cans. Rotor is particularly suitable for the use of ogival aluminum cans.

Rotor is developed for deodorant spray products, usable with all range of micromist insert (MBU), and for anti-perspirant spray products, with AP standard insert.
