Definitions

  • the present invention relates to a spraying device for fluid products and more particularly to such a spraying device for delivering at least two doses of product.
  • WO 93/02804 discloses a device such as a bidose, comprising a tank mounted on a base and a pusher for actuating the device. A portion of the pusher cooperates with a split ring disposed in a groove in the outer wall of the reservoir, so that to be able to dispense the first dose, it is necessary to store a certain force in the user's hand, until the split ring comes out of its groove.
  • the document device WO 93/02804 provided to provide a second groove in the outer wall of the tank and to arrange a second split ring, so that after actuation of the device to expel the first dose, the entire pusher plus first split ring is stopped by the second ring disposed in this second groove. Then, to spray the second dose, it is necessary again to store a certain force to release the second split ring from its groove and thus distribute the second dose.
  • This device works satisfactorily but may however have certain disadvantages. Thus, since only a small amount of product is contained in the tank, a main objective is to keep the cost of said sprayer as low as possible so as not to adversely affect the final selling price of the product.
  • the device disclosed in the document WO 93/02804 comprises a number of different component parts that are necessary to perform the functions of energy storage and dose splitting.
  • the manufacture and assembly of these different component parts can therefore be relatively expensive.
  • the tank and the base because of the presence of the two peripheral grooves on the outer surface of the tank, it is almost impossible to make the tank and the base in one piece, said grooves being located in the hollow annular space defined ink the tank and the base.
  • the use of mobile means to perform the energy accumulation function may cause risks of malfunction in case of breakage or jamming of said split rings.
  • EP-0 546 607 discloses a unit dose comprising a peripheral groove in the inner wall of the body cooperating with a peripheral ridge in the outer wall of the reservoir to prevent accidental actuation of the device.
  • the disadvantage of this type of device is the difficulty of achieving a simple and inexpensive molding. Indeed, the groove in the inner wall involves the use of an undercut and therefore a relatively complicated mold.
  • EP-0 311 863 discloses a bidose comprising dose splitting means which are arranged on a piece fitted on the body and cooperating with the reservoir. It does not include energy storage means and involves the use of an additional piece, the molding of which has the same disadvantages as those described above, namely a complicated and expensive mold.
  • the present invention aims to provide such a device for spraying fluid products which does not have the aforementioned drawbacks.
  • the present invention aims to provide a device for spraying fluids, comprising a minimum of component parts.
  • the present invention also aims to provide such a device that provides a reliable operation while ensuring a manufacturing cost, including molding, and mounting as low as possible.
  • the present invention also aims to provide a device for spraying fluids such as a bidose, capable of ensuring a perfect spray of the entire of each dose, while being simple to manufacture, mount and use, with the lowest cost possible.
  • the subject of the present invention is therefore a device for spraying a fluid product according to claim 1.
  • the dispensing device comprises a reservoir 11 containing the product to be dispensed mounted on a base 14, a dispensing member such as a pump, a manual actuating element 20, such as a pusher, for actuating the dispensing member to dispense product, said actuating member 20 being provided with an outlet port 29 by which will be sprayed said product.
  • the pump comprises a piston 1 sliding in the reservoir 11, the inside of which is connected to the outlet orifice 29 by an expulsion channel 3.
  • a nozzle 2 is disposed in said expulsion channel to promote the spraying .
  • the device comprises means for fractionating the dose 16.
  • the fractionating means are intended to split the contents of the reservoir in two or more doses, thus transforming the distribution into a multidose, advantageously a bidose, that is, to say a device distributing two doses of product.
  • a bidose that is, to say a device distributing two doses of product.
  • the example shown in the figures relates in particular to a nasal spray, which functions as a bidose, a dose being provided for each nostril.
  • the invention is not limited to this particular application.
  • the invention provides energy storage means 12 which cooperate with the actuating element 20 when the sprayer is actuated to accumulate energy. energy in the user's hand.
  • said energy accumulation means cooperate with said actuating element 20 in that they deform elastically when a predetermined minimum force is exerted on it.
  • said base 14, said energy storage means 12 and said dose splitting means 16 are made in the form of a single one-piece piece 10.
  • This implementation makes it possible to reduce the number of component parts and thus the cost of manufacturing and mounting the dispensing device.
  • the manufacture and assembly of the device are simplified since it is no longer necessary to provide mobile means (split rings) to accumulate energy.
  • the reliability of the device is also improved, a split ring that can break or get stuck during the actuation of the device.
  • the reservoir 11 is preferably also made in one piece with the one-piece piece 10, which preferably comprises two concentric hollow cylinders, the inner cylinder defining the reservoir 11, and the outer cylinder forming the base 14 having on the outer surface said energy storage means 12.
  • the two concentric cylinders are preferably connected by a substantially horizontal annular flange at their lower ends, thereby defining an annular hollow space between the inner surface of the base 14 and the outer surface of the tank 11.
  • the device comprises besides the energy storage means 12 and the dose splitting means 16, indexing means 15.
  • the indexing means are intended to selectively prevent or allow the actuation of the device, in particular to ensure safety against unwanted actuation, for example during transport.
  • said indexing means are made in one piece with the one-piece part 10, which is in particular visible in FIG. 9.
  • these indexing means are made in the form one or more thickenings provided on the inner surface of the base 14, said thickening extending over a portion of the periphery of said inner surface. They cooperate with the actuating element 20 to selectively prevent or allow axial displacement of said actuating member 20 relative to said one-piece piece 10.
  • said thickenings 15 cooperate with one or more projecting lugs 25 inside. of the actuating element 20, preferably axially, and abutting said thickenings in the rest position where the actuation is prevented. In this first position of the actuating element, shown in particular in Figures 1 and 3a, any force exerted on the actuating element 20 will have no effect and no product will be distributed by the device.
  • attachment means 19 on said one-piece piece 10, advantageously on the upper peripheral edge of the base 14.
  • These attachment means 19 can cooperate with one or more shoulders 22 provided on the lower peripheral edge of the actuating element 20.
  • these attachment means 19 may comprise, for example in the first position of the element actuator 20, that is to say the rest position where the actuation of the device is prevented, a particular form 19a facilitating the attachment of the element actuator 20 on the base 14 during assembly.
  • This particular form may for example be carried out as a ramp 19a which makes it possible to progressively deform the actuating element 20 at the level of the shoulders 22, said shoulders 22 then snap under said attachment means 19.
  • this particular form 19a hooking means 19 defines the position in which the actuating element 20 is mounted on the one-piece piece 10, which advantageously corresponds to said first position of the actuating element.
  • the actuating element 20 is preferably rotatably mounted on the one-piece part 10.
  • the user wishes to dispense the product, he rotates the actuating element 20 with respect to the one-piece part 10 around its main axis, towards a second position of the actuating element 20, or waiting position, in which the indexing means 15 no longer cooperate with said actuating element 20.
  • this second position of the actuating element 20, represented in particular in FIG. 3b the lugs 25 provided inside the actuating element 20 do not rest on the thickenings 15 of the one-piece part 10, so that an operation is no longer prevented.
  • the one-piece part 10 comprises on its outer surface first rotational stop means 18a for defining the direction of rotation between its first and second positions, and second rotational stop means 18b for defining the second position of the element.
  • these rotational abutment means may be made by projections projecting from the outer surface of the one-piece piece 10 and cooperating with said shoulders 22 of the actuating element 20 when the rotation of it.
  • the energy storage means are advantageously made in the form of one or more lugs 12, in particular in the form of two diametrically opposite lugs, arranged on the outer surface of the one-piece piece 10.
  • said lugs 12 cooperate with the shoulders 22 of the actuating element 20 and generate a certain resistance against an axial displacement of the actuating element 20 relative to the one-piece part 10.
  • the user wants to spray a dose, it exerts a force on the device which urges the actuating element 20 in axial displacement on the one-piece piece 10, this displacement being prevented by the lugs 12.
  • the actuating element 20 preferably being made in an appropriate plastic material, it may deform elastically and thus, said shoulders 22 can pass over said lugs 12 when a minimum force of determined is exerted on the device.
  • This threshold corresponding to this minimum force thus makes it possible to accumulate energy in the user's hand and, when the shoulders 22 of the actuating element 20 pass over the lugs 12 of the one-piece part, all of this energy accumulated in the hand of the user is transmitted in one fell swoop to the device so that the entire dose is sprayed. There is no risk of doing a partial run, which would result in a partial distribution of the dose.
  • the device comprises fractionating means 16 for splitting the contents of the reservoir 11 in two doses, preferably equal.
  • said fractionating means 16 are made in one piece with the one-piece part 10.
  • said fractionation means are formed by one or more thickenings 16 which form, with the thickening (s) 15 acting as a means indexing, at least one step in the axial direction.
  • second thickenings 16 extend according to the invention to a second part of the inner surface of the base 14 in extension of the first thickenings 15, and thus cooperate at the end of the expulsion of the first dose with said tabs 25 of the actuating element 20 for stopping the axial displacement of the actuating element 20 with respect to the one-piece part 10.
  • said dividing means 16 also act as the second indexing means, since they prevent, in the position reached after the distribution of the first dose, the distribution of the second dose.
  • a particularly advantageous embodiment is achieved by two diametrically opposed thickenings which, on a part 15, extend to the upper peripheral edge of the base 14 to form the first indexing means, and on a second part 16 , extend only up to about half the height of the hollow annular space between the base 14 and the reservoir 11 to form the fractionating means also acting as second indexing means. At least a portion of said inner surface should be free of thickening to allow movement of the actuating member 20 to dispense the second dose.
  • the actuating element 20 is turned on the one-piece part 10 to a third position, where the tabs 25 no longer cooperate with the second thickenings 16, thus allowing the distribution of the second dose.
  • second energy storage means 13 are also provided, preferably also in the form of projecting lugs on the outer surface of the one-piece piece 10, two lugs 13 being advantageously also diametrically opposite one another. to the other.
  • third rotational stop means 18c which make it possible to define said third position of the actuating element 20, and which are advantageously made similarly to the first and second rotational stop means 18a and 18b.
  • said first energy accumulation means 12 and said second energy accumulation means 13, respectively formed by a pair of diametrically opposed lugs, are made of such so that the two pairs of lugs are offset axially and angularly relative to each other on the outer surface of the base.
  • the user to actuate the device, first turns the actuating element 20 from its first position, where the actuation is blocked, to its second position, then it distributes the first dose, then it again turns the actuating element from its second position to its third position, and then actuates the device again to dispense the second dose.
  • Another particular advantage of the energy storage means disposed on the outer surface of the one-piece piece 10 is that said pins can also act as a dose control. Indeed, when the two lugs 12 and 13 are visible, this means that no dose has been dispensed. When one of the two lugs is visible, this means that only the first dose has been dispensed, and when no lug is no longer visible, this means that both doses have been distributed.
  • the one-piece part 10 incorporates the base, the reservoir, the energy storage means, the indexing means, the dose splitting means. , the rotational stop means defining the angular positions of the actuating element, and the attachment means for holding the actuating element on the one-piece part.
  • the present invention thus makes it possible to save several component parts of the device. Since the energy storage means are not provided in the hollow annular space defined between the base and the reservoir, but on the contrary on the outer surface of the base, said one-piece piece can be made simple and economical, for example by molding.
  • the component parts of the device can all be mounted using simple and inexpensive molds because they have no counterparts. -dépouilles.
  • the mounting of the device is also greatly facilitated due to the small number of parts.
  • the manufacturing and assembly costs of the device of the invention are therefore particularly low without affecting the reliability of its operation.
  • the present invention obviously also applies to multidoses comprising more than two doses, in which case the means of fractionation and energy accumulation. can be provided several times.
  • the tank 11 may not be an integral part of the one-piece piece, but be fixed thereto, for example by snapping.
  • the interior of the tank 11 may also be provided with a glass cylinder or other suitable material, to improve the seal.
