PREFERRED EMBODIMENT OF THE INVENTION

[0029] A detailed explanation of a preferred embodiment of the object of the present invention is provided below with the aid of the aforementioned figures.

[0030] The device for diffusing volatile substances, shown in FIGS. 1-2, essentially comprises a container (1), an upper closing element (2) which serves as a lid for the container (1) and a wick (3) jointed to the closing element (2), which in turn comprises an upper end and a lower end. Inside the container (1) there is a reservoir intended to contain a predetermined volume of a liquid volatile substance and connected with the outside through an opening. The lower end of the wick (3) protrudes into the liquid, while the upper end protrudes from the liquid and from the container (1).

[0031] A lower section of the wick (3) extends over the length into the liquid of the reservoir, an upper section of the wick (3) protrudes from the container (1) and an intermediate section of the wick (3) lies in an area inside the container (1) but outside the liquid.

[0032] The closing element (2) comprises at least one internal perimetral grove (4), which in this preferred embodiment is located near a lower end. The closing element (2) also has an outer diameter which corresponds to the outer diameter of the container (1). At the upper end of the closing element (2) there are through holes (5), as well as external ribs conceived to ease the handling of the device.

[0033] The container (1) has in turn a lower neck (6) on which a groove with no thread pitch (7) is defined. Therefore, the container (1) and the closing element (2) are movably connected to each other by respectively the groove with no thread pitch (7) and the internal perimetral grove (4), which work together for an adjustment of the relative position between both elements. In turn, the closing element (2) slides upwards and downwards across the container (1) using the lower neck (6) of the container (1) as a guide.

[0034] At it can be seen in FIGS. 3b, 4b and 5b, in this preferred embodiment the groove with no thread pitch (7) comprises three protrusions (8) that define three correspondent positions for the closing element (2): a first lower position, a second intermediate position and a third upper position. On each of them the internal perimetral grove (4) is blocked by one of the positions of the groove with no thread pitch (7), thereby defining three different exposure degrees of the wick (3).

[0035] On the closed position of the device shown on FIGS. 1 and 2 the container (1) and the closing element (2) are mutually joint to each other by means of a correspondent internal mutual closing thread (9) which prevents an undesired opening of the device with the subsequent diffusion of the vapours during the storage, transport and/or exhibition of said device.

[0036] On the preferred embodiment described here, the closing element (2) further comprises vertical internal ribs (10) that reinforce its resistance. In this case, the internal perimetral grove (4) is made over a lower end of each rib (10), therefore being discontinuous.

[0037] Starting from the closed position shown on FIGS. 1 and 2, when a user wants the device to emit the volatile substance contained therein has firstly to unscrew the closing element (2) from the container (1), therefore operating on the closing thread (9).

[0038] Once separated from the container (1), the closing element (2) slides upwards relative to the container (1), manually operated by the user, and the closing element (2) lifts off relative to the container (1) until the internal perimetral grove (4) is intercepted by the lower protrusion (8), as seen in FIGS. 3a-3c. In this position, vapours from the wick soaked with the liquid volatile substance pass through the through holes (5) to the air space surrounding the device.

[0039] On a situation in which further evaporation is needed, the user manually turns and pulls up the closing element (2) up to a second position, as shown in FIGS. 4a-4c, or even up to a third position, as shown in FIGS. 5a-5c. On each of these positions, the internal perimetral grove (4) is intercepted by respectively the intermediate protrusion (8) and the upper protrusion (8).
