In fact, as is known, on the market there are deodorants for the car and the ambient composed of a receptacle containing perfumed liquid essence and a perfume- diffusing top applied to its neck, whether or not acting as a lid.

For all products on the market, perfume diffusion is originated up by moistening the diffuser top by means of a dipping cylinder or wick made of wood, cord or other material which draws the fragrant liquid contained in the receptacle by capillary action towards the said perfume-diffusing top which may be made of wood, felt, cork, cardboard, etc., having various esthetical shapes.

With this method, the wick constantly absorbs and feeds the diffusing material.

This, once saturated, discharges the excess of essence into the ambient, dripping on to underlying surfaces and causing damage (sometimes irreparable) to dashboards, etc.

Moreover, since it is not possible to control the flow, the essence is consumed rapidly, so limiting the length of perfume emanation.

The inventor of this invention has devised a diffusing receptacle without these drawbacks which, quite simply, makes it possible to dose the quantity of liquid reaching the above-mentioned top in porous material by merely turning the receptacle upside-down, without having to insert either wicks or other types of dipping elements.

In fact, the subject of this invention is composed of a diffusing receptacle of the type described in the preamble to claim 1 enclosed, characterised by the contents of the part characterising this claim.

Hereunder, some examples of the receptacle according to this invention are given in detail and with reference to the enclosed drawings which represent: -figure 1 represents a frontal view of the receptacle according to the invention in a vertical position with the top facing upwards; -figure 2 represents a frontal view of the receptacle according to figure 1, with the fragrant liquid in contact with the top; -figure 3 represents a frontal view of another example of the receptacle according to the invention with a ball inside situated on the bottom of the receptacle when in a vertical position with the top facing upwards; -figure 4 represents a frontal view of the example given in figure 3 with the receptacle upside-down and the ball closing the neck of the receptacle; -figure 5 represents a frontal view of another example with the receptacle in a vertical position with the top facing upwards; of the two balls therein contained, one pushes downwards against the upper part of a segment in the neck of the receptacle, whilst the other lies on the bottom; -figure 6 represents a view of the example given in figure 5, with the receptacle upside-down and one of the two balls pushing against the opposite side of the segment, whilst the other remains between the segment and the top; Considering first the figures 1 and 2, a first example of a diffusing receptacle 1 (hereafter called"receptacle") composed of a glass bottle with a neck 5 and a top 2 in porous material (preferable beech-wood or similar). It is to be noted that in this patent application, the word"neck"is used purely to indicate the open portion of the receptacle to which the top is fixed, without necessarily implying that this neck has a different diameter to the other parts of the receptacle, which may have varying forms and shapes.

The receptacle 1 is connected to some means of suspension, in this case a leather lace 3 or any other material used for this type of application. This lace 3 keeps the receptacle 1 in a vertical position, with the fragrant liquid 4 (hereafter called "liquid") therein contained not in contact with the porous top 2.

In this situation, the top 2, also acting as a lid, is dry and there is no emanation of perfume outside the receptacle 1.

If the receptacle is turned upside-down, as illustrated in figure 2, by turning it with respect to the suspension lace 3, the liquid 4 comes into contact with the top 2 which, being in a porous material, absorbs a certain amount and then slowly evaporates to the outside, diffusing the perfume of the essence contained in the liquid 4.

To reach this objective, it is sufficient to keep the receptacle 1 upside-down for a few seconds, since the porous material of which the top 2 is made, rapidly absorbs the liquid. After a few seconds, to avoid any superfluous liquid dripping out of the top, it is necessary to put the receptacle 1 back into its original position with the top 2 facing upwards. To facilitate this operation, the inventor has designed the receptacle 1 in such a way that its centre of gravity G and its top 2, in any position whatsoever and with any quantity whatsoever of liquid inside, are on opposite sides of the area where the suspension means are connected, in this case the lace 3, as can be seen in the enclosed drawings. This weight distribution ensures that, when the user leaves hold of the receptacle 1 a few seconds after having turned it upside- down, this receptacle, suspended by means of the lace 3 (obviously hanging from a hook or some other protruding element), revolves within the area where the lace 3 is connected, automatically returning to its original position with the top 2 facing upwards. So, the top 2 emanates the perfume for several days as a result of evaporation of the liquid it previously absorbed: when all the liquid has evaporated, it is sufficient to repeat the operations described above, and the cycle is repeated.

In order to avoid undesired dripping of the liquid from the top 2, resulting from the user keeping the receptacle 1 upside-down for too long, the inventor has provided for the insertion of a ball 6 into the receptacle 1' (see figures 3 and 4), made of a material with a higher specific gravity than that of the liquid 4, and the presence of an annular grooved area 7 in the neck 5 of the receptacle 1', of a size such that, when upside-down (fig 4), this ball pushes against it as a result of gravity, so creating sufficient sealing against any further passage of the liquid 4. In this way, the volume of liquid entering into contact with the porous top 2 is limited to the amount present in the area of the receptacle 1'between the annular area 7 and the top 2. When the receptacle 1'is facing upwards, the ball 6 is inconsequential and lies on the bottom of the receptacle 1', as can be seen in figure 3.

In a further design of a receptacle 1"according to the invention, the inventor has provided for the formation of the annular area of the neck 5 in the shape of a segment 7', as can be seen in figures 5 and 6, and the insertion of a second ball 6', similar to the one 6 described above, into that part of the receptacle 1"between the segment 7'and the top 2 in such a way that, when the receptacle 1"is facing upwards, the second ball 6', through the effect of gravity, pushes against the segment 7'which is directly opposite, so creating a seal which prevents the liquid present in the area between the segment 7'and the top 2 from flowing back. In this way, a single dose of the liquid 4 is isolated within this part of the receptacle and in contact with the top 2, so that it is not even necessary to turn the receptacle 1" upside-down for a few seconds to bring about absorption of a determined quantity of the fragrant liquid 4. As can be seen in figure 6, the other ball 6 carries out the function described above, i. e. limiting, when the receptacle 1"is upside-down, the quantity of liquid between the segment 7'and the top 2 to the minimum necessary to form the said dose.

Naturally, the type, shape and proportions of the various elements making up a receptacle according to the invention, may be varied with respect to the examples illustrated herein but always referring to that set forth in the enclosed claim 1, not going beyond the limits, therefore, of the protection granted by this patent application. For example, the suspension means may be of a different type, with metallic elements pivoted or hinged together, etc.
