[0055]In accordance with the present invention, the capsule 5 comprises a lower half-container 6 and an upper half-container 7 in sealed mutual engagement, delimiting a reservoir chamber 50 in which the substance S is contained. In other words, in accordance with the present invention, the mutual coupling between the lower half container 6 and the upper half-container 7 delimits a reservoir chamber 50 in which the substance S is housed in a liquid state.

[0056]In accordance with the present invention, the lower half-container 6 comprises a lower plate 61 with an extension substantially orthogonal to the axis X-X engageable by the command group 3. [0057]In other words, in accordance with the present invention, in a configuration with the capsule 5 mounted to the main body 2, the lower half-container 6 is directly engaged with the command head 315 to receive the vibratory action. [0058]In particular, in accordance with a preferred embodiment, the lower plate 61 comprises an engagement portion 610 suitable to be engaged by the command group 3 and to receive the command action thereof.

[0068]According to a preferred embodiment, the reticular outflow portion 710 is made of a material belonging to the family of metals and metal alloys. For example, in a preferred embodiment, the reticular outflow portion 710 is made of titanium. For example, in a preferred embodiment, the reticular outflow portion 710 is made of platinum. For example, in a preferred embodiment, the reticular outflow portion 710 is made of stainless steel. [0069]According to a further preferred embodiment, the reticular outflow portion 710 is made of a polymeric material or a ceramic material. For example, in a preferred embodiment, the reticular outflow portion 710 is polyether-ether-ketone (PEEK). [0070]In accordance with the present invention, the lower plate 61 and the upper plate 71 are mutually movable relative to each other in the direction of the axis X-X. Preferably, this movement corresponds to the atomization of the substance S through the reticular outflow portion 710.

[0071]According to the present form of the invention, the movement of the upper plate 71 involves the nebulization of the liquid substance, which outflows through the area 710. [0072]In other words, the movement of the upper plate 71 results in a pump effect on the substance S, which, crossing the holes 710' of the reticular outflow portion 710, is dispensed towards the outside of the capsule 5. [0073]In accordance with a preferred embodiment, the vibratory action produced by the command group 3 on the lower plate 61 is transmitted to the upper plate 71 by the substance S present in the reservoir chamber 50. That is to say, the vibrations emitted by the command group 3 on the lower plate 61 create a series of longitudinal waves in the substance S, parallel to the axis X-X that are discharged on the upper plate 71.

[0074]According to a preferred embodiment, the upper half container 7 comprises an annular element 72 engaged with the upper plate 71. Said annular element 72 has an elastically yielding behavior so as to allow the vibrational movement of the upper plate 71 with respect to said axis X-X.

[0079]According to a preferred embodiment, the lower plate 61 and the upper plate 71 are spaced along the axis X-X by a distance between 2 and 12 tenths of a millimeter.

Preferably, said distance varies according to the features of the substance and therefore according to the capillarity of said substance. [0080]Therefore, preferably a liquid film of the substance

S is arranged between the lower plate 61 and the upper plate 71.

[0081]In accordance with a preferred embodiment, the substance S is positioned between the lower plate 61 and the upper plate 71 by capillarity.

[0082]According to a preferred embodiment, the reservoir chamber 50 comprises an atomization region 51, corresponding to the space present between the lower plate 61 and the upper plate 71. [0083]In particular, the substance S arranged in said atomization region 51 transmits the longitudinal waves which the lower plate 61 is subject to, to discharge them to the upper plate 71. Free to vibrate axially, the upper plate 71 is therefore suitable to perform a pumping action on the substance itself, which is then dispensed out of the capsule 5. In other words, the combined vibrations of the lower plate 61 and of the upper plate 71 create a pump effect, which generates the aerosolization of the substance S generated in crossing the holes of the upper plate 71. [0084]In accordance with a preferred embodiment the reservoir chamber 50 comprises a reservoir region 52 distal from the axis X-X and surrounding the atomization region 51.

X-X, a larger section than the section of the atomization region 51.

[0086]In accordance with a preferred embodiment, the reservoir region 52 extends in height parallel to the axis X-X. In particular, the reservoir region 52 extends in height substantially starting from the lower plate 61. [0087]Therefore, preferably the substance S, subject to the force of gravity, flows towards the atomization region 51.

[0088]In accordance with a preferred embodiment, the reservoir region 52 is inclined towards the axis X-X. In other words, the reservoir region 52 has such an extension as to be incident towards the X-X axis at the lower plate 61 or at an imaginary area below the lower plate 61.

[0089]In accordance with a preferred embodiment, the lower half-container 6 comprises a lower body 63 supporting the above-described components, suitable to engage the upper half-container 7 and the main body 2. [0090]Preferably, the lower body 63 is a single element made of plastic material.

[00104] In accordance with a preferred embodiment, the upper half-container 7, preferably the upper body 73, comprises a diffuser 730, positioned in a region axially consecutive to the upper plate 71, suitable to facilitate the atomization of the substance S in the axial direction.

[00105] Preferably, the upper plate 71 is axially positioned on the bottom of the diffuser 730.

[00106] In accordance with a preferred embodiment, the command group 3 further comprises a command motherboard 32 operatively connected to the piezo-electric vibratory element 31 to switch it on and command it in vibration. [00107] Furthermore, according to a preferred embodiment, the command group 3 comprises a power supply member 33 suitable to electrically power the piezo- electric vibratory element 31 and the command motherboard 32. Preferably, the power supply member 33 is a rechargeable battery.

[00108] In accordance with a preferred embodiment, the command group 3 also comprises switch-on elements suitable to command the automatic switching on of the command group 3, with consequent atomization of the substance, according to the user's presence.

That is to say, depending on the capsule 5 and in particular on the amount of substance S comprised therein, the command motherboard 32 is suitable to regulate a vibratory action of varying length in time. [00110] For example, said switch-on elements detect the user's presence by detecting the inhalation action thereof.

[00112] According to a preferred embodiment, the nebulizer device 1 comprises a conveyor element 90, of the nasal type 91 and/or of the oral type 92 suitable to convey the substance S towards the user's airways. [00113] Preferably, the conveyor element 90 comprises openings 900 suitable to allow the entry of air from the external environment. Preferably, said air mixes with the atomized substance S into the conveyor element 90 to then reach the user's airways. [00114] According to a preferred embodiment, the conveyor element 90 is removably mountable to the main body 2. According to a preferred alternative embodiment, the conveyor element 90 is removably mountable to the capsule 5 mounted to the main body 2.

[00123] Advantageously, as the substance is consumed, it is disposed in the atomization region of the reservoir chamber by capillarity. Advantageously, as the substance is consumed, it is disposed in the atomization region of the reservoir chamber, because it is subject to the force of gravity. Advantageously, as the substance is consumed it is disposed in the atomization region of the reservoir chamber, subject to a suction action.

[00124] Advantageously, the capsule is mountable and dismountable. [00125] Advantageously, the capsule is provided as a disposable instrument.

[00126] Advantageously, the capsule does not run the risk of obstruction phenomena, for example of the holes. [00127] Advantageously, the use of the nebulizer device is foolproof.

[00128] Advantageously, the substance is hygienically sealed in the capsule, thus making it impossible to contaminate it from the outside.

[00129] Advantageously, a cycle of therapies can include the consumption and use of a predefined number of capsules. Advantageously, the capsules are easy to transport (similarly to the transport of a tablet or a blister of tablets for oral use).

[00130] Advantageously, the nebulizer device is suitable to be used for different therapies, by replacing the capsules.

[00131] Advantageously, the nebulizer device performs the atomization operations of the substance only when the user is inhaling, while it blocks the atomization operations when the user is exhaling, avoiding any waste of substance, and therefore of drug.

[00132] It is apparent that, in order to meet contingent needs, those skilled in the art may make changes to the subject of the present invention described above, all contained within the scope of protection defined by the following claims.
