DESCRIPTION OF A PREFERRED EMBODIMENT

[0022] As shown in FIG. 1, the bracelet for the diffusion of volatile substances according to the present invention comprises a strap 1 and a refill 2 which is impregnated with volatile substances and replaced when it is used up.

[0023] The strap 1 is of a conventional type, for example, one that is made of an elastomeric-type plastic material, such as silicone. For the placement thereof on a user's wrist, the strap 1 comprises a eyelet 12 arranged at one end of the strap 1, into which there is introduced the opposite end of the strap 1 comprising a fixing element 11, for example, a protrusion, which is introduced into one of the holes 9 made on the strap 1 located close to the end provided with the eyelet 12.

[0024] The refill 2 is also preferably made of a plastic material, for example, ethylene-vinyl acetate (EVA), and is placed in a housing made in a position substantially centered in the strap 1. To make the placement thereof easier, the inner surface 22 of the refill 2, i.e., the surface in contact with the strap 1 or with the user's wrist in the usage position thereof, is smooth.

[0025] For the detachable fixing to the strap 1, the refill 2 comprises a perimetral rib 5 that abuts with a flange 6 of the strap 1, as can be seen in FIG. 3. Furthermore, the detachable fixing is also performed by means of a protrusion 8 housed inside a securing hole 7 centrally located in the refill 2. The refill 2 can therefore be placed and removed in a simple manner.

[0026] The refill 2 is introduced into a housing 10 of the strap 1 taking advantage of the elastomeric nature of said strap 1, in other words, with the circumferential walls of the housing 10 deforming elastically. To achieve the foregoing, the material of the strap 1 has a Shore A hardness of preferably between 50 and 80, and more preferably of 70.

[0027] To increase the evaporation surface of the refill 2, said refill 2 comprises on its outer surface 21, i.e., the surface exposed to the outside in its usage position, at least one rib 3, defining at least one evaporation chamber 4.

[0028] It must be indicated that, in the depicted embodiment the refill 2 comprises two ribs 3, defining two evaporation chambers 4 that are concentric to one another and an additional evaporation chamber 4 with the perimetral rib 5. However, it is obvious that the refill 2 may comprise any suitable number of ribs 3 and evaporation chambers 4.

[0029] According to the depicted embodiment, said ribs 3 define an oval shape when seen in a plan view. However, said ribs 3 may form any suitable shape, for example, a circular, square, or rectangular shape, which may be closed, like in the case of the depicted embodiment, or open.

[0030] The evaporation rate is increased with the bracelet according to the present invention as a result of the presence of ribs 3, defining the evaporation chambers 4, such that more volatile substances evaporate from the refill 2 though it is still the same size.

[0031] Furthermore, the refill can be placed and removed in a very simple and reliable manner since it has a double retention, on one hand by means of the perimetral rib 5 and the flange 6, and on the other hand by means of the securing hole 7 and the protrusion 8.

[0032] Although reference has been made to a specific embodiment of the invention, it is obvious for one skilled in the art that the bracelet described is susceptible to a number of variations and modifications, and that all the mentioned details can be replaced with other technically equivalent details without departing from the scope of protection defined by the attached claims.
