PREFERRED EMBODIMENT OF THE INVENTION

[0026] A detailed explanation of an example of a preferred embodiment of the object of the present invention is given below with the help of the above-mentioned figures.

[0027] The device for diffusing volatile substances described, shown in the enclosed figures, comprises a container (1), a cover (2) for closing the container (1), equipped with a slot (3), and a diffusion wick (4) that can be fitted into the slot (3), which is partially covered by a cap (5).

[0028] The container (1) is made up of a hollow prismatic body, which has an interior housing (6) delimited by lateral walls (7) and a closed lower base (8), and an upper opening (9). The housing (6) is sized and configured to contain a volume of a volatile substance, usually in liquid form and consisting of a fragrance or an insecticide composition. This container (1) is made of a plastic material, which in this case is polypropylene.

[0029] The lid (2) of the container (1) has a geometry and dimensions corresponding to those of the opening (9) which it covers, as well as including couplings (10) for physical coupling with the body of the container (1). As indicated above, this cover (2), which is made of a plastic material, preferably polypropylene, has a longitudinal slot (3) for connecting the inner housing (6) with the outer medium to the device.

[0030] The diffuser wick (4) can be fitted transversely in the groove (3) to allow controlled release of the volatile substance from inside the housing (6). To this end, the diffuser wick (4) is made up of a body of porous plastic material that allows capillary flow through it. In this preferred embodiment, the body is laminated and has a rectangular geometry, and the plastic in which it is made is sintered polypropylene.

[0031] Thus, the diffuser wick (4) has a first end (11), which can be turned towards the housing (6), a central sector (12) which can be fitted into the slot (3), and a second end (13), which can be turned outwards. The volatile substance inside the housing (6) impregnates the first end (11) of the diffuser wick (4), with which it is in direct contact, and flows upwards by capillary action to the central sector (12) and finally to the second end (13), through which it is released by volatilisation into the surrounding environment, as can be seen in FIGS. 3.3 and 4.2.

[0032] The cap (5) consists of a plastic part, preferably made of polypropylene, configured and sized for coupling and covering the second end (13) of the diffuser wick (4), to prevent the release of the volatile substance by volatilisation during transport and storage of the device, or during any period when it is desired to prevent such release.

[0033] In the first preferred embodiment that is being described, in which all the components are made of polypropylene, they are assembled solidly and mutually by means of ultrasonic welding.

[0034] In a second preferred embodiment, in which the assembly between the components of the device is carried out by physical means, this device incorporates at least one adjustment and sealing element, not shown in the attached figures, which ensures correct coupling of the diffuser wick (4) in the slot (3) and prevents possible leaks and spillage of the contents of the housing (6) of the container (1).

[0035] An alternative design is also envisaged in which the diffuser wick itself (4) incorporates additional elements for coupling with the groove (3), thus avoiding the need for the adjustment and sealing element. In this alternative embodiment, in which the diffuser wick (4) is moulded, the additional coupling elements consist of a defined extension in the central sector (12) for locking and sealing inside the slot (3).
