Definitions

• the present invention relates to a device for the spray dispensing of a liquid product, particularly for medical products, pharmaceuticals, cosmetics or the like.
• Single-dose spray dispensing devices are known and used for the administration of drugs, cosmetics or the like via auricular, sublingual, inhalation and dermal route.
• administrations are particularly preferred when the immediate absorption of drugs or other substances is required, and this occurs by carrying out the administration through the mucous membranes with a high degree of vascularization.
• multi-dose spray dispensing devices capable of dispensing a predefined dose of drugs in solution through the aid of nebulizers.
• Single-dose dispensing devices are also known, i.e. small containers comprising nebulizers that contain a dose sufficient for a single treatment or, possibly, for two treatments.
• Such a dispensing device comprises a plastic container, containing a dose of liquid product, associated with a suitable nebulizer insert, kept under ambient pressure conditions and without the aid of a further gaseous substance with a different pressure than the ambient one.
• the dispensing of the liquid product takes place by means of the manual compression and deformation of the outer walls of the plastic container.
• one of the main drawbacks is linked to the fact that such dispensing devices contain both liquid product and air and, at the end of the compression of the plastic container, a residual amount of product remains inside the container itself, that is particularly difficult to extract and therefore to use.
• the main aim of the present invention is to provide a device for the spray dispensing of a liquid product that allows to minimize the residual liquid product inside the device itself at the end of dispensing.
• One object of the present invention is to provide a device composed of elements that, not being in contact with the liquid product and thus uncontaminated, can be reused for further applications, thus reducing the use of material and the related production costs and times.
• Another object of the present invention consists in the realization of a more ergonomic structure which allows to simplify the administration operations of the liquid product by the user, even for applications on mucous membranes which are difficult to reach.
• Another object of the present invention is to provide a device for the spray dispensing of a liquid product that allows to overcome the mentioned drawbacks of the prior art within the ambit of a simple, rational, easy, effective to use and affordable solution.

• Figure 5 is a sectional view of the device according to the invention in the compression configuration.
• reference number 1 globally designates a device for the spray dispensing of a liquid product L.
• the device 1 comprises: at least a deformable containment body 2 containing at least an aeriform substance A;
• At least a containment tank 3 associated with the containment body 2 and able to contain at least a liquid product L;
• valve element 4 placed between the containment body 2 and the containment tank 3 and suitable for the unidirectional passage of the aeriform substance A from the containment body 2 to the containment tank 3;
• aeriform substance substantially air, although alternative embodiments of the invention cannot be ruled out wherein the aeriform substance is a different type of gas.
• the deformation of the containment body 2 is able to push the aeriform substance A through the valve element 4 to pressurize the containment tank 3, and push the liquid product L through the dispensing unit 14, 15, 16 for dispensing the liquid product L in spray form along a dispensing direction X.
• the containment body 2 comprises at least a bellows element 5, 6 compressible along a compression direction Y.
• the bellows element 5, 6 comprises a first axial extremity 5 and a second axial extremity 6 opposite the first axial extremity 5.
• first axial extremity 5 and the second axial extremity 6 are arranged substantially along the compression direction Y.
• the second axial extremity 6 has a substantially circular shape and comprises a grip element 10 to facilitate grasping by the user.
• the bellows element 5, 6 is deformable between a rest configuration wherein the first axial extremity 5 is arranged away from the second axial extremity 6 and the aeriform substance A is substantially contained within the containment body 2, and a compression configuration wherein the first axial extremity 5 is arranged substantially close to the second axial extremity 6 and the aeriform substance A is pushed at least partially within the containment tank 3.
• the bellows element 5, 6 is compressed by a user who, by grasping simultaneously the first axial extremity 5 and the grip element 10 with one hand or with both hands, pushes the first axial extremity 5 towards the second axial extremity 6 along the compression direction Y as far as the first axial extremity 5 is substantially in contact with the second axial extremity 6.
• the aeriform substance A is transferred from the containment body 2 to the containment tank 3 passing through the valve element 4.
• valve element 4 is movable between a closing configuration wherein the valve element itself is closed and blocks the passage of the aeriform substance A, and an opening configuration wherein the valve element 4 is open and allows the passage of the aeriform substance A within the containment tank 3.
• valve element 4 is substantially of the type of a check valve that allows the passage of the aeriform substance A, along the compression direction Y, within the containment tank 3, preventing the passage thereof along the direction contrary to the compression direction Y, in this case from the containment tank 3 to the containment body 2.
• valve element 4 prevents the liquid product L from passing from the containment tank 3 to the containment body 2, while keeping clearly separate the containment body 2 from the containment tank 3, and therefore the aeriform substance A from the liquid product L.
• the containment tank 3 is associated with the containment body 2 by interposition of at least a junction element 7 having a substantially elbow shape and able to make the compression direction Y and the dispensing direction X substantially transversal to one another.
• the containment body 2 is associated directly with the containment tank 3 without the interposition of the junction element 7, and the compression direction Y coincides with the dispensing direction X; or other embodiments wherein the containment body 2 is associated with the containment tank 3 by interposition of a different junction element 7 which maintains the compression direction Y coincident with the dispensing direction X.
• the device 1 comprises:
• At least a glass-shaped element 11, 12 coupleable to the tubular body 8 and able to cooperate with the tubular body 8 and the valve element 4 to define the containment tank 3.
• the tubular body 8 comprises, in a substantially median position, at least a base surface 9 able to house the valve element 4.
• the base surface 9 is arranged substantially transversal to the dispensing direction X and comprises an interlocking seat, arranged substantially at the center of the base surface 9, wherein the valve element 4 is fitted to measure.
• the glass-shaped element 11, 12 comprises at least a side wall 11 and at least a bottom wall 12.
• the side wall 11 has a substantially tubular shape able to couple to the tubular body 8.
• the bottom wall 12 comprises at least a passage opening 13 for the passage of the liquid product L; preferably, on the bottom wall 12 are formed several passage openings 13 circularly arranged with respect to the center of the bottom wall 12.
• the dispensing unit 14, 15, 16 comprises:
• the elongated pin 14 is associated with the bottom wall 12, from which it extends overhanging on the opposite side with respect to the side wall 11.
• the elongated pin 14 is arranged substantially at the center of the bottom wall 12 and the passage openings 13 are circularly arranged with respect to the elongated pin 14.
• an elongated interspace 16 for the passage of the liquid product L.
• the elongated interspace 16 extends along the entire length of the elongated pin
• the elongated interspace 16 comprises at least a terminal section 17 with a substantially spiral shape suitable for the nebulization of the liquid product L.
• the terminal section 17 has a substantially circular shape and comprises a plurality of abutment protrusions 20 associated with the inner surface of the terminal section 17.
• the terminal section 17 allows the liquid product L to travel along a substantially whirling path which facilitates the nebulization of the liquid product itself.
• the dispensing unit 14, 15, 16 comprises at least an outlet opening 18 suitable for the passage and the dispensing outwards of the liquid product L.
• the outlet opening 18 is formed on the cap element 15 at the terminal section 17 and the abutment protrusions 20 are arranged circularly around the outlet opening 18.
• the device 1 comprises a closing element 19 associable by screwing with the cap element 15 for the closure of the outlet opening 18 and to prevent the contact between the liquid product L and the external environment.
• the user grasps the containment body 2 with one hand, or with both, preferably by placing the thumb on the first axial extremity 5 and one or more fingers on the grip element 10.
• the bellows element 5, 6 is compressed and the aeriform substance A contained in it is pushed substantially entirely first within the junction element 7 and then it comes in the proximity of the valve element 4.
• the pressure exerted by the aeriform substance A on the valve element 4, facilitates the opening of the valve element itself, which passes from the closing configuration to the opening configuration, allowing the passage of the aeriform substance A within the containment tank 3.
• the release of the first axial extremity 5 in the opposite direction to the compression direction Y returns the valve element 4 to the closing configuration preventing the aeriform substance A and/or the liquid product L from flowing back within the containment body 2.
• the entry of the aeriform substance A in the containment tank 3 generates such a pressure to push the liquid product L through the passage openings 13 to be channeled inside the elongated interspace 16.
• the crossing of the terminal section 17 with a spiral shape transmits a swirling motion to the liquid product L such as to facilitate the nebulization of the liquid product itself and the dispensing through the outlet opening 18 in the form of very fine particles.
• the separation of the containment body from the containment tank allows to keep substantially separate, and therefore protected, the liquid product from the aeriform substance, from exchange with the outside, and therefore from any contamination, allowing to avoid the possible use of preservative substances to preserve and maintain the properties of the liquid product to be administered. Furthermore, this separation allows to reuse the containment body itself for other applications with a consequent reduction in the materials used, production costs and times for making the device.
