  • Such a device is known from document EP 0 452 728.
  • bidoses contain only a small amount of product, the manufacturing cost of the dispensing device must obviously be kept as low as possible.
  • the product being able to be a pharmaceutical product, the precision of dosage and the quality of the distribution must be optimal.
  • the ease of use is also a very important criterion in devices with one or two doses.
  • the manufacturer of the product to be distributed is often different from the manufacturer of the distribution device distribution, it is very desirable that the filling of the tank, as well as the tools necessary for this filling are as simple and as inexpensive as possible, and preferably correspond to a standard type filling and tooling known by the manufacturers of fluid product.
  • the present invention aims to provide a product distribution device fluid, in particular a two-dose device, which provides optimal performance in the quality of the distribution as well as the reliability of operation, while being very simple and inexpensive to make and assemble.
  • the bidose of document FR-2 761 281 has nine parts. It is an object of the present invention to provide a bidose-type dispensing device consisting of a lower number of rooms.
  • the present invention also aims to provide a dispensing device of fluid, in particular a bidose, in which the reservoir consists of a standard tank whose filling is well known and therefore simple for the manufacturer of the product to be distributed, without the need for complicated special tools and expensive.
  • the present invention also aims to provide a dispensing device of fluid, in particular a bidose, which simultaneously guarantees perfect tightness of the product contained in the tank and perfect spraying of each dose of product each time the device is actuated.
  • the present invention also aims to provide a device for distributing fluid product, in particular a bidose, in which the total distribution of the dose is guaranteed on each actuation and for which any accidental actuation or not desired is impossible.
  • the present invention therefore relates to a product distribution device fluid according to claim 1.
  • said tip comprises a shutter part deformable for sealingly closing said downstream opening at rest and deform during actuation of the device to open said downstream opening, and a spray part to form a spray profile when dispensing product.
  • said spray part of the end piece cooperates with the bottom wall of said external body to define the profile of spray when actuating the device.
  • said tip comprises a central cylindrical stud forming on one side the shutter of the downstream opening of the syringe, and on the other side, a surface flat, said pad being moved axially when the device is actuated for a on the one hand open the downstream opening of the syringe and on the other hand press the said flat surface against the bottom wall of the outer body incorporating swirl channels of such that said pad defines the spray profile during actuation.
  • said end piece is made in one piece in one elastomeric material
  • said actuating rod axially movable by the user to distribute the product, cooperates with an external body provided with means of energy accumulation to create an energy accumulation in the fingers of the user guaranteeing the distribution of the entire dose at each actuation.
  • said body and said actuating rod cooperate to prevent accidental actuation of the device.
  • said syringe comprises two doses of product, and said body external forms a stop in the axial stroke of the actuating rod, to separate this in two partial strokes corresponding to each of the doses.
  • said rod actuation after the expulsion of the first dose, said rod actuation must be rotated relative to said external body to ability to expel second dose.
  • the external body comprises cooperating non-return means with said rod so as not to allow rotation and / or axial displacement of the rod respectively only in one direction.
  • said external body incorporates a window at the level of the syringe to view the dose to be expelled.
  • said external body is made in one piece.
  • the fluid dispenser of the The present invention advantageously comprises only five parts. It is a reservoir 10, advantageously produced in the form of a syringe body comprising a hollow body 11 provided with an upstream opening 12 and a downstream opening 13.
  • the upstream opening 13 is sealed off by a plug 40 adapted to form the delivery piston when actuated via a rod actuator 30, while the downstream opening 13 is sealed in a sealed manner by a tip 50.
  • the assembly formed by the syringe 10, the tip 50, the plug piston 40 and the actuating rod 30 is then fixed in an external body 80.
  • the external body 80 incorporates the orifice of distribution 20 and is adapted to cooperate with the actuating rod 30 to ensure a correct actuation of the device.
  • the external body 80 includes a window 89 at the level of the reservoir 10 for viewing the contents of said exterior from the outside tank. This characteristic is particularly advantageous in the case of a bidose because it allows to know if the first dose was distributed or not.
  • the reservoir 10 is, as mentioned previously, preferably formed by a syringe body. This greatly facilitates the filling of the tank, since the filling syringes is well known and widely mastered by the manufacturers of fluid product. In this way, the syringe 10 is pre-filled and then its two openings upstream and downstream 12 and 13 are plugged by means of the piston plug 40 on the one hand and the end piece 50 on the other hand, so that the unit formed by the reservoir 10 and the two caps 40 and 50 can be pre-filled before the final assembly of the the invention. It is therefore not necessary to provide the manufacturer with a fluid product special tools to assemble a complicated device simultaneously with filling, or to fill an already assembled device
  • the end piece 50 advantageously simultaneously provides three functions. On the one hand, it hermetically seals the downstream opening 13 of the syringe 10. On the other hand, it provides precompression during distribution. Finally, it includes means adapted to form a spray profile at the dispensing orifice 20 of the device for, upon actuation of the device, distribute so finely sprayed, the dose of product.
  • This tip preferably made in one part made of an elastomeric material, is more precisely represented in FIGS. 6 to 9. It advantageously comprises a fixing part 54 for fixing on said opening 13 of the syringe 10, advantageously by snap-fastening.
  • the tip 50 has other share a deformable shutter part 51 acting as a shutter at rest in sealing the syringe, said closure portion 51 being adapted to deform during actuation of the device, in particular under the effect of the pressure of the product, to open the downstream opening 13 of the reservoir and allow the expulsion of a dose of product.
  • said shutter 51 is produced in the form of a stud 52 which fits tightly into a reduced diameter part of the outlet of the syringe 10, and which under the effect of the pressure of the product moves towards a part of larger diameter of said syringe outlet thus freeing the passage for the product.
  • the end piece 50 also advantageously comprises a part spray 56 adapted to form a spray profile 55 during dispensing of the product.
  • This spraying part 56 is advantageously produced in the form with a flat surface and can in particular be produced on the opposite side of the stud 52 forming the shutter 51.
  • the lower part of the stud 52 forming the shutter 51 closes the syringe 10 while the upper part of the stud forming the spraying part 56 is arranged away from the end wall or bottom wall 81 of the member 80.
  • this bottom wall 81 of the external member 80 incorporates spray channels or other suitable spray profiles, and when the pad 52 is deformed or moved to open the shutter part 51, as shown in the FIG.
  • the spray profile 55 is therefore formed by the cooperation of the tip 50 and the external member 80.
  • the wall bottom 81 of the external member 80 can then be planar and form the bottom of said profile.
  • the device includes means for accumulating energy in the user's hand, preferably made between the external body 80 and the actuating rod 30.
  • these energy storage means can be produced by small studs or pins 85 formed in the internal surface of the external member 80 and which cooperate with an actuating plate 35 integral with the rod 30 on which the user presses to move said actuating rod 30.
  • a force predetermined is necessary to pass over these pins, so that the user stores energy in his fingers until he reaches this force, the energy being then suddenly released, guaranteeing the total distribution of the dose.
  • These pins also act advantageously to prevent unwanted actuation of the device.
  • the member outer 80 has two grooves in which the radial ends extend and said plate 35, thus preventing rotation of the actuating rod during actuation thereof.
  • the external member 80 has two grooves which are offset on the periphery of the external member, so that to expel the second dose, it is necessary to rotate the actuating rod 30 to present the actuating plate 35 facing the second groove.
  • similar energy storage means 85 are advantageously provided to guarantee the total expulsion of the second dose.
  • the device also advantageously includes non-return means which act both on the axial displacement of the rod 30 and on the rotation movement of it.
  • ramps 86 which allow the passage of the actuating plate 35 in one direction but prevents its movement In the opposite way.
  • means may be provided to prevent actuation of the device and requiring a rotation prior to the rod actuation 30 before the first dose can be expelled.
  • the present invention therefore provides a device for dispensing a fluid product, advantageously a bidose, which consists of only five pieces and which provides simultaneously all of the following functions: shutting off the tank outlet at rest and between the two doses; precompression when each dose is expelled; spraying of each dose by creating a spray profile at the time of distribution; accumulation of energy in the user's hand before each dose expulsion; transport security to prevent accidental activation; anti-return function after the first dose preventing the actuating rod from returning in its starting position; creation of an autonomous assembly consisting of the syringe, of the piston plug and the obturator end allowing a separate and easy filling of said syringe and providing a device in which the product is in contact only with two materials, namely the material of the syringe, generally glass, and that of the two plugs, generally an inert elastomeric material.
  • the present invention has been described with reference to the drawings which represent a preferred embodiment thereof, but various variations and modifications could be made to the invention without departing from the scope thereof, as defined by the appended claims.
  • a spring is armed which is then released by the actuation of a means of appropriate triggering, the spring then acting on the actuating rod 30 to expel the dose (s).
  • the present invention is not limited to bidoses, but also applies to monodoses, and devices containing a limited number of doses, for example, three or four.
