Abstract

This invention relates to a diffusing device for volatile liquids to affect the immediate environment, or perfume or deodorize a room; such device comprising a bottle (1) containing the liquid for diffusion (2), in which a wick (M) is partially immersed; a cover cap (3) fitted to the said bottle by means of a snap-on system (3a), capable of being rotated but not moved in a vertical direction, and provided with slits or ports (F) for the passage of the air; a wick-holder (11-13) fitted to the neck (6) of the said bottle by means of a snap-on system and prevented from rotating, and taking the form of a sleeve provided with slits or ports (V) for the passage of air and with an external screw thread; and an internal cap (10) consisting of an internally-threaded skirt (15) designed to engage with external thread (16) of the said wick holder, and having in addition vertical grooves on the outside (14) designed slidably to engage with a vertical sleeve (9) which forms an integral part of the upper portion of the aforesaid cap (3), and of an internal sleeve (12) forming a sealing-cap for aforesaid wick.
