Definitions

  • the invention concerns the disclosure of a nubulizer particularly suited to be applied on bottles containing liquid substances for medical, cosmetical or hygienic/sanitary use.
  • nebulizers are devices permitting the dispersion in the air or in any gaseous substance of a liquid in the form of very minute drops.
  • Nebulizers are largely used particularly in the cosmetic and the hygienic/sanitary fields, where they are applied to containers holding liquids which are then nebulized and dispersed in the air or spread on people's bodies.
  • nebulizers which are used in the above-mentioned fields of application, consist essentially of an under-cap, which is applied on the neck of the container and presents a tube-shaped duct with a tiny tube attached to it, which draws the liquid held in the container.
  • the under-cap is complete with a pin with a spraying hole having a helicoidal-tapered cross-section and the nebulizer is usually protected by a cap which is usually inserted by pressure or by screwing on the container.
  • the small tube is inserted in a swirl chamber belonging to the under-cap, into which the liquid held in the container is conveyed, after it has been pushed upwards through the tube.
  • the liquid is pushed upwards by the mechanical deformation of the container, if the latter is deformable and elastic or, in other cases, by the pressure exerted by a compressed gas, for instance freon, held in the container itself, when the latter is rigid.
  • a compressed gas for instance freon
  • the liquid undergoes a first disintegrating process which will be further incremented when, after it has already been reduced to minute drops, it goes through the hole with a tapered helicoidal cross-section of the pin applied to the under-cap, before it is conveyed outside into the environment.
  • nebulizers belong to the known technique, which are used not only in the above-mentioned fields of application, but also in the industrial fields, wherein the liquid held in the container is sucked by means of compressed air through a small tube drawing from the container and is sent into the outside environment in a nebulized form by exploiting the known Venturi principle.
  • nebulizers The main inconvenience presented by the known types of nebulizers consists in that the degree of nebulization of the liquid they achieve is often rather coarse, since it consists of a plurality of tiny drops dispersed in the air, rather than of a mist.
  • Another inconvenience consists in that before spraying it is necessary to remove the protective cap, which may be lost, thereby causing uneasiness to the user.
  • the present invention proposes to eliminate the described inconveniences and has the main purpose of disclosing a nebulizer which yields a higher degree of nebulization of the sprayed liquid in comparison with the nebulization obtained with the nebulizers belonging to the known technique.
  • Another purpose is to disclose a nebulizer obtaining a very fine nebulization preventing the collection of drops on the spraying hole and, therefore, the formation of drippings during the spraying process.
  • Another purpose is to disclose a nebulizer wherein the cap is constantly attached to the bottle or to the container holding the liquid to be sprayed.
  • nebulizer which can be completely pre-assembled in all of its parts, regardless of the container which will receive it, so that the only task of the bottling company will be to connect the nebulizer with the neck of the bottle with a single screwing operation.
  • nebulizer which can be applied on a bottle and which, in accordance with the claims, comprises:
  • the nebulizer according to the invention has two swirl chambers rather than a single one, and more precisely, a primary chamber which is comprised between the edge of the small tube and the interior of the holow cylindrical section of the under-cap, and a secondary chamber which is coaxial with the former and is comprised between the outer part of the cylindrical section of the under-cap and the innerly hollow cylindrical section of the cap, so that it permits a very fine nebulization of the liquid contained in the bottle, the degree of said nebulization being much finer than the degree of nebulization obtained with the nebulizers of the known type.
  • the small tube, the under-cap and the cap can be assembled together, so that the nebulizer thus assembled can be applied by the customer around the neck of the bottle by simply screwing it on the outer thread of the bottle neck.
  • the annular peripheral part of the under-cap penetrates under pressure into the opening of the bottle neck and insures the stable junction of the nebulizer to the bottle.
  • the nebulizer according to the invention which is indicated as a whole with 1, is applied on a bottle 2, which is of the elastic and deformable type and contains the liquid to be nebulized.
  • nebulizer is represented in its longitudinal cross-section in Fig. 2, where it is possible to observe the parts composing it, which consist of an under-cap 3, presenting an annular peripheral section 4 which is inserted into the bottle neck 5, which it seals, and a central cylindrical section 6, which is co-axial with the peripheral annular section 4, which is innerly hollow.
  • the small tube 7 which is immersed in the liquid 8 contained within the bottle. Its end 30, which is opposed to the immersed end, is flush against the spacing teeth 9 of the under-cap 4, which are visible in a clearer detail in Fig. 5. Said teeth match the holes 10, which are more clearly visible in Fig.
  • the external area of the under-cap 3, with which the holes 10 connect the inside of the bottle, is, as can be obeserved in Fig. 2 and even better in Fig. 3, another chamber 13, comprised within the inner hollow part of a cylindrical section 14, belonging to the cap 15 of the nebulizer. Said cap is applied around the bottle neck 5 by tightening it on thread 16. Said chamber 13 acquires various volumes, as can be seen in the Figs. 2 and 3, which are comprised between the minimum value represented in Fig. 2, when the cap 15 is completely tightened, up to the maximum value represented in Fig. 3, when the same cap 15 is untightened to the end of its stroke. It can also be observed that, when the chamber acquires its minimum volume, i.e. when cap 15 is completely tightened around the bottle neck, a stopper 17 having a conical profile at its top end and being arranged centrally in the central cylindrical section 6 of the under-cap 3, seals hermetically the spraying hole 18 bored in cap 15.
  • cap 15 In order to spray the liquid 8 contained within bottle 2, one must, first of all, untighten cap 15 and bring it to the position represented in Fig. 3, so that the stopper 17 of the under-cap 3 no longer shuts the spraying hole 18. It will be pointed out that in the position of maximum opening represented in Fig. 3 cap 15 still remains attached to the bottle neck 5, since an annular rim 40 belonging to the latter contrasts against an annular rim 41 belonging to cap 15, which prevent the separation of one from the other. At this point, by pressing the body of the bottle 2, a pumping action is conveyed to the liquid 8, contained therein, which ascends vertically through channel 19 of the small tube 7, following the direction indicated by the arrows 20.
  • the primary swirl chamber When the liquid reaches chamber 12, which will be called the primary swirl chamber, it undergoes a first, coarse nebulization process, since it violently dashes against the spacing teeth 9; the partially nebulized liquid is conveyed through the holes 10 which carry it to the next chamber 13, which will be called the secondary swirl chamber.
  • the secondary swirl chamber the liquid, which has already been nebulized in the primary swirl chamber 12, undergoes another nebulizing process by dashing against the walls of the chamber and against the body of the stopper 17, which is positioned at the center of the chamber itself.
  • the nebulized liquid dashes against the inner edge 22 of the spraying hole 18, where it undergoes yet another nebulization process, before it is sent out into the outside environment 24 with a jet 21, which acquires its tapered shape from the shape of the spraying hole 18, which diverges outwardly in its section 25 connecting it to the outside environment 24.
  • the inner rim 22 of section 23 converging toward the exterior 24 of the spraying hole 18 consists of a circular depression 33, co-axial with the central circular section 27 of hole 18.
  • said inner rim 22 can also be made by shaping the converging section 23 of the spraying hole 18 following other geometrical shapes or by shaping the entire converging surface 23 according to suitable geometrical shapes. After the spraying operation has been completed, cap 15 will be tightened completely around the bottle neck and the stopper 17 will hermetically seal the spraying hole 18.
  • said fine nebulization 21 prevents the collection around the spraying hole 18 of several drops, and, as a consequence, it prevents drippings along the outer surface of cap 15.
  • the shrinking of the peripheral annular section 4 of the under-cap 3 into the bottle neck 5 occurs at the same time as the tightening of cap 15.
  • cap 15 it is necessary to force cap 15 to its end stroke, in order to force the annular projection 41 of cap 15 to go over the safety projection 40 belonging to the bottle neck 5.
  • the small tube 7 presents a plurality of longitudinal splines 31, which fulfil the important task of permitting a faster re-entry of air within the volume 11 of the bottle, when the mechanical outside pressure, which has produced the spraying of liquid 8 to the exterior, is released.
  • Fig. 9 represents a different embodiment of the nebulizer according to the invention, wherein the under-cap 60 presents some characteristics permitting it to be tightened directly around the neck of the bottle receiving it and it also presents a central stopper suited to the application of small tubes of the cylindrical type, rahter than of the type with the complex cross-section, which has been described in the preceding example of embodiment. More specifically, it will be observed in Fig. 9 that the under-cap 60 is so shaped as to present in its peripheral rim an indentation 61 acting as an undercut and contrasting against the protruding rim 71 of the bottle neck 70.
  • stopper 75 it can be observed still in Fig. 9, that its lower part presents a triangular or, at any rate, polygonal shape, while the central cylindrical section 96 of the under-cap 60 presents some projections 97, as can be observed also in the detail represented in Fig. 10.
  • the small tube 77 of the type with a cylindrical cross-section which can be normally found on the market, can easily be inserted by contrast between the lower part 76 of stopper 75 and the projections 97 of the central cylindrical section 96 of the under-cap 60.
  • Said junction creates some channels 78 and 98 through which air flows going through hole 82, the holes 90 and the channels 78 and 98, after the nebulization action has stopped and the bottle recovers its original volume, after the deforming action, which has caused the spraying, has ceased.
  • Fig. 9 offers the advantage of obtaining a nebulizer with an under-cap which is essentially immune from entrainment due to the friction caused by the cap, when the latter is screwed and unscrewed. Moreover, it is possible to use small tubes of the cylindrical type which are easily found on the market and inexpensive, for the construction of the nebulizer. These advantages are achieved simply by changing the shape of the terminal part of the stopper of the under-cap.
  • the terminal section of the stopper has a triangular shape, but obviously any type of polygonal or star shape, or at any rate any shape not coinciding with the circle can permit the formation of the channels 78 and, thereby reach the proposed purpose.
