Definitions
- the present invention relates to a two-phase dispensing device in spray form of a single dose of fluid product. More generally, the invention relates to a miniature sprayer, preferably disposable, adapted in particular to the sample in the fields of pharmacy or perfumery.
- the dispensing device according to the invention can also find applications in the pharmaceutical field. In this particular area, it is important that the dose of product contained in the dispenser is expelled in its entirety. In addition, it is also important that the spray is of good quality.
- a disposable vaporizer produced by welding sheet of plastic defining between it a reservoir and two swirl channels connected to a spray orifice.
- the product is discharged into the swirl channels and then through the spray orifice to create a jet of sprayed product.
- This jetadle vaporizer does not however allow to expel a defined dose of product.
- the production of swirl channels by welding two plastic sheets is rather imprecise and random.
- the esc tank divides into two chambers by a partition which breaks under the action of pressure. One chamber is filled with a fluid when the other contains another product and air.
- the reservoir is separated from the spray orifice by a breaking point.
- the partition breaks and the two fluids mix more or less with each other and with the air. In any case, the elage thus obtained cannot be homogeneous.
- the breaking point breaks and the non-homogeneous mixture is forced back towards the spray orifice.
- the and which leaves the orifice is sometimes composed of the first fluid, sometimes composed of the second fluid and sometimes of air, but never of a homogeneous mixture of the three. It follows that the jet is sometimes purely aqueous and sometimes biphasic. Its quality is therefore not constant.
- a device for dispensing in sprayed form a single dose ⁇ e fluid product characterized in that it comprises: - a reservoir of fluid product containing the single dose and connected to a spray orifice, at least one gas tank connected to said spray orifice, and means for simultaneously emptying the fluid and gas tanks, so as to create a two-phase spray of fluid and gas at the spray orifice.
- a spray gas mixed with the product at the level of the spray orifice guarantees good spray quality of the single dose of product expelled.
- the use of a spray gas makes it possible to avoid pressure force requirements to be applied in the case of a simple pump fitted with a swirl nozzle. Less pressure is enough to ensure a good quality spray.
- the reservoirs comprise deformable wall elements of the soup making it possible to empty the reservoirs by pressing on said wall elements.
- the pressure allowing the spraying is directly exerted on the tank.
- the emptying means comprise a pressure member for pressing on the flexible wall elements deformable at the tanks. The pressure member indeed allows complete emptying of the product reservoir, which ensures a precise quantity of product expelled.
- the tanks are arranged in such a way that the emptying of said at least one gas tank begins before the emptying of said tank of fluid product.
- the tanks are arranged in such a way that the emptying of said at least one gas tank ends after the emptying of said fluid product tank.
- the pressure member presses on the flexible wall elements of said at least one gas tank before pressing on the flexible wall element of said fluid reservoir. It is thus guaranteed that the entire volume of the dose is emitted with an optimal spray quality, that is to say with a simultaneous emission of gas under pressure.
- the reservoirs comprise outlet channels connecting them to the spraying orifice, the pressure member being formed by a substantially rigid combined tongue articulated relative to the reservoirs so as to gradually press on the elements of tank walls starting at their ends furthest from the outlet channels. A progressive and simultaneous emptying of the fluid and gas reservoirs is thus achieved.
- the reservoirs are formed between a substantially rigid support and a flexible barrier film forming the elements of flexible deformable walls.
- the support can be made of polypropylene, polyethylene or a mixture of these
- the barrier film can be made by superimposing a layer of polyester, aluminum, polyamide and polyethylene.
- the tongue is formed by an actuating part of the support which is profiled in a domed manner and connected by a hinge to another main part of the support carrying the reservoirs.
- the outlet channels and the spray orifice are formed between the support and barrier film.
- the barrier film is welded or glued to the support.
- a retention and dispersion fiber is placed before the spray orifice.
- the fiber is placed both between the outlet channels and the spray orifice and between the support and the barrier film.
- the spray orifice is closed by a removable plug member.
- a removable plug member By making or incorporating all of the organs of the distribution device between a support and a barrier film glued or welded together, it is possible to produce the device at very low cost.
- the fiber placed just before the spray orifice allows good dispersion of the product droplets soaked in the fiber and traversed by the flow of pressurized air from the gas tanks.
- FIG. 1 is a plan view of a single-phase two-phase distribution device produced according to the present invention
- FIG. 2 is a sectional view through the distribution device of FIG. 1.
- the single-phase biphasic distribution device of FIGS. 1 and 2 is shown on an enlarged scale: in reality, the distribution device is part of a rectangle of approximately 6 cm by 3 cm. As for its thickness, it does not exceed 5mm and preferably will be less than 3mm when the device is intended to be included in a magazine as an advertising sample.
- the dist ⁇ oution device essentially comprises three constituent elements, namely a substantially rigid support 10, a flexible barrier film 11 and a fiber pad 17, the function of which will be explained below.
- the substantially rigid support 10 can be made of any material in the form of a sheet giving a certain rigidity.
- the support 10 is made of polyethylene, polypropylene or a mixture of these.
- the flexible barrier film 11 can be made of any material in the form of a flexible sheet capable of being deformed by simple pressing, for example using a finger.
- the film 11 is produced by a superposition of layers of polyester, aluminum, polyamide and polyethylene to thereby form a barrier complex.
- the barrier film 11 is welded or heat-bonded to the substantially rigid support 10 over most of the surface of the support. In certain determined locations, the barrier film 11 is not welded to the support 10 and a volume is therefore formed between the film and the support.
- a main part 1 of the support 10 which comprises a total of three parts, namely the main part 1 mentioned above, an actuating part 2 connected to the main part 1 by a hinge 21, and a part of head 3 connected to the main part 1 by a tear line 31.
- the film 11 can be heat-sealed on the three parts 1, 2 and 3 of the support 10, but at least the film 11 extends over the main part 1 and the head part 3 of the support 10.
- the actuating part 2 is then only constituted by the support 10.
- the hinge 21 which connects the actuation part 2 to the main part 1 of the support 10 can be produced in the form of a line or of several lines of lesser thickness which promotes the folding of the part 2 relative to part 1. As can be seen in FIG.
- the actuating part 2 presents in cross section a curved profile whose convexity is oriented on the same side as the film 11 for reasons which are given below.
- the determined zones of the main part 1 of the support 10 on which the barrier film it is not heat-sealed define several reservoirs 12, 13, 12, several channels 14, 15, 16, a housing 18 intended to accommodate the fiber pad 17 as well as a spray orifice 19.
- the spray orifice 19 is closed by the head part 3 which acts as a removable plug member.
- the spraying orifice 19 is in fact closed off by the fact that the barrier film 11 is heat-sealed on the support 10 in the head portion 3. Just upstream of the spraying orifice 19 is the receiving housing for the fiber pad 17.
- the two lateral tanks 12 are connected by respective outlet channels 14 to a common channel 16 which opens into the receiving housing 18 of the fiber pad 17.
- the central tank 13 is also connected by a channel outlet 15 to the common channel 16 connected to the reception housing 18.
- the three reservoirs are connected to the spray orifice via a network of channels 14, 15, 16 and of the reception housing 18 accommodating the tampon of fiber 17.
- the fiber 17 must be as flat as possible.
- the fiber 17 and its housing 18 may thus have a cylindrical section to form a nose piece.
- the two side tanks 12, 12 are gas tanks, preferably filled with air.
- the central reservoir 13 As for the central reservoir 13, it is filled with fluid corresponding to the single dose to be dispensed. Simultaneous pressure on the three reservoirs 12, 13, 12 has the effect of expelling the respective fluid (fluid product, gas) through the respective conduits 14, 15, 14, then through the common channel 16 in the receiving housing 18 accommodating the fiber pad 17. The mixture of fluid and gas which has already operated in the common channel 16 is completely dispersed and divided through the fiber pad 17.
- the jet of fluid product at the outlet of the spraying orifice thus has very good spraying quality on the one hand due to the mixing of the fluid with a gas resulting in a two-phase mixture, and on the other hand due to the presence of the fiber pad 17 which acts as a disperser to divide the fluid product into very fine droplets propelled by the gas.
- the pressure exerted on the tanks 12, 13, 12 can be carried out using one or more fingers, but preferably, as shown in Figures 1 and 2, the dispensing device is provided with a pressure or tab in the form of the actuating part 2. Thanks to this pressure member 2, simultaneous pressure on the reservoirs is ensured, as well as perfect emptying. This pressure and emptying result can be obtained by bending the pressure member 2, as previously defined. Due to this bending, the pressure member 2, once folded down on the main part 1, begins by pressing on the flexible deformable walls produced by the flexible barrier film 11 starting from their end furthest from the channels of outlet 14, 15, 14. The bending of the pressure member 2 ensures a progressive flattening of the reservoirs so that it is not possible for fluid to remain in the reservoirs. This ensures a simultaneous progressive emptying of the entire contents of the tanks.
- the gas reservoirs 12, 12 extend more towards the hinge 21 than the fluid reservoir 13, so that the pressure member 2 once folded down first begins by pressing on the gas tanks 12 before pressing on the fluid reservoir 13.
- the emptying of the gas reservoirs 12, 12 thus begins before the emptying of the fluid reservoir 13.
- the gas reservoirs 12 extend further away from the hinge 21 than the fluid reservoir 13. This means that gas will continue to be expelled after the fluid reservoir 13 is emptied. Thanks to this characteristic, a perfect quality of two-phase spraying is ensured by again preventing fluid from being expelled without prior mixing with gas. In other words, the biphasic spraying of the fluid product is preceded and followed by an expulsion of gas under pressure.
- the dispensing device Due to the low number of constituent elements of the dispensing device according to the invention, it can be produced at low cost with relatively simple manufacturing techniques. In addition, because of its thin thickness, preferably less than 3 mm, it can easily be packaged and stacked without any risk. It should be clearly understood that the number of gas reservoirs and of fluid products of the embodiment which has just been described is completely arbitrary and may vary without departing from the scope of the invention.
