System for diffusion of auto-perforant perfume in car, has destruction unit likely to be solicited by stopper to destroy cover due to screwing of stopper on collar towards final position in which stopper is screwed in stroke end on collar

摘要

The system has a lower bottle containing a liquid perfume, and an upper stopper for diffusion of porous material i.e. wood, where the stopper is likely to be screwed on a collar of the bottle. A destruction unit (28) is arranged for destruction of a cover (30) interposed between the stopper and the bottle. The destruction unit is likely to be solicited by the stopper to destroy the cover due to screwing of the stopper on the collar of the bottle towards a final position in which the stopper is screwed in a stroke end on the collar of the bottle.
