Problems solved by technology

[0010] Therefore, the service life of the box is very short: this life corresponds to the time required for the fragrance to evaporate, i.e. a few days
To compensate for this rapid aging, it is of course possible to increase the volume of the fragrance, but the constant diffusion of the fragrance will be uncontrolled due to the intensity and volume of the fragrance that has evaporated and can be uncomfortable

Embodiment Construction

[0019] The solution according to the invention consists in using an all-mechanical energy system for generating a diffusive quality similar to the level of an electrical device, without using an external electrical energy source, and immobilizing the olfactory molecules in a polymer-type matrix.

[0020] Immobilization of olfactory molecules to substrates

[0021] The matrix element is solid. The matrix element is at least partially made of polymer material. Polymers include elastomers such as polyamides and copolymers of the polyether block amide type. Depending on the polymer material and fragrance used, the beads allow the fragrance molecules to diffuse naturally for 6 to 18 months only in an imperceptible manner. Examples of such materials are (trade name).

[0022] In fact, the matrix element spontaneously diffuses the small number of fragrance molecules it contains, by natural evaporation or more particularly by the phenomenon of desorption.

[0023] On the other h...

Abstract

The invention relates to a fragrance delivery system comprising at least one cartridge (1) containing solid elements loaded by adsorption with an olfactory composition and opened by a grid (5) havingholes, the cross-section of which is smaller than the cross-section of the solid elements. The cartridge (1) is mounted on a cartridge holder holding the cartridge and connected to a mounting base (2)on a fixed portion by an unstable linkage capable of ensuring an oscillating movement of the cartridge holder around a reference position.

Description

technical field [0001] The present invention relates to the field of diffusion of fragrance substances using solid holders in which odorous molecules are adsorbed which are released into the atmosphere by spontaneous diffusion or by means of a gas flow. The invention relates in particular to the field of fragrance diffusion in the passenger compartment of a vehicle (car, rail vehicle, aircraft, ship, etc.) using a replaceable capsule comprising a matrix element to which the fragrance is adsorbed. [0002] More specifically, the present invention relates to passive diffusion systems that offer the advantage of not requiring energy input. Fragrances are placed in the open air, and different air movements are used to diffuse the fragrance into the atmosphere. Background technique [0003] Known in the prior art is European patent application EP1932545, which describes a container for the diffusion of volatile substances impregnated with solid or semi-solid material, characteri...
