Definitions
- the present invention relates to a fluid product dispenser
- a fluid product dispenser comprising a fluid product pump having a pump body defining a fluid product inlet, at least two fluid product reservoirs, and a stopper integral with the fluid product reservoirs.
- the cap forms a receiving housing, the cap defining two connecting ducts each connecting respectively a reservoir of fluid product.
- the dispenser can deliver one or more doses from the first reservoir or one or more doses from the second reservoir, or even one or more doses from both reservoirs at the same time.
- the preferred field of application of the present invention is that of perfumery and cosmetics, without forgetting pharmacy.
- a standard pump is a pump whose body is of axial revolution with a single central axial fluid inlet.
- the dispenser of document WO2001000521 A1 probably suffers from leaks, in particular between the pump body and the cap at the level of the two fluid product inlets. Indeed, the passage section variation takes place by a shearing movement between two plates, resulting in a hazardous seal.
- the main purpose of the present invention is to revise the design of this dispenser of the prior art, so that a standard pump can be used. Another goal is to improve the seals by dispensing with a shearing movement.
- the present invention proposes a fluid product dispenser comprising a fluid product pump comprising a pump body defining a fluid product inlet, at least two fluid product reservoirs, a stopper integral with the fluid product reservoirs, the plug forming a receiving housing, the plug defining at least two connecting ducts each respectively connecting a reservoir of fluid product, the dispenser further comprising a nozzle secured to the pump body, the nozzle defining an interior space communicating with the inlet of fluid product from the pump body and at least two through orifices connecting the outside of the end piece with its interior space, the end piece being rotatably mounted in the housing for receiving the plug, so as to establish fluid paths between the connecting ducts of the cap and the orifices of the nozzle.
- the end piece which forms the interface between the pump body and the cap, it is possible to use a pump of standard design, the body of which is integral in rotation with the end piece, so that a torque exerted on the pump causes the tip to rotate in the cap.
- the pump body can have a symmetry of revolution around an axis of revolution, the fluid inlet being unique and located on the axis of revolution.
- the through-orifices of the end piece can be offset axially, that is to say located at different axial heights.
- the end piece can comprise a pump neck and the pump can comprise a fixing ring in engagement with the pump neck.
- the user can grasp the fixing ring and cause it to rotate so as to cause the endpiece to rotate in the housing for receiving the stopper.
- the cap may comprise an axial retaining housing, the endpiece comprising a skirt engaged in the axial retaining housing, while allowing the endpiece to rotate in the cap.
- the tip is therefore held axially on the cap, but can rotate in the receiving housing.
- the pump body can form an inlet pipe defining the fluid product inlet on the inside, the endpiece forming a sleeve for leaktight reception of the inlet pipe.
- This inlet tubing is a very classic feature for a standard pump.
- the end piece may comprise two cylindrical sections which are respectively rotatably mounted in two barrels of the housing for receiving the stopper, the orifices of the end piece extend radially and open outwards respectively at the level of the two cylindrical sections.
- the pump of the dispenser of document WO2001000521 A1 defines two axial inlets
- the end piece defines two radial orifices
- the pump conventionally defines a single central axial inlet. The end piece thus makes it possible to redirect the single axial inlet towards two radial orifices leading to cylindrical sections mounted in rotation in respective barrels.
- the drums can be formed with passage grooves which communicate with the connecting ducts, these passage grooves being able to be respectively aligned with the orifices by rotation of the endpiece in the stopper.
- the rotation of the cylindrical sections in their respective barrels can define at least two communication positions corresponding to two fluid paths, in which a single connecting conduit is connected to a single respective orifice by a passage groove.
- a third communication position can be provided, in which the two connecting ducts are simultaneously and respectively connected to the two orifices by two other passage grooves, in order to distribute a mixture of fluid products from the two reservoirs.
- the barrels may comprise an upper barrel and a lower barrel, the upper barrel advantageously having a larger diameter than the lower barrel, each barrel forming two passage grooves, the upper barrel thus comprising a direct passage groove which is directly connected to the connection conduit and an indirect passage groove which is connected to the connection conduit by an annular channel, which connects the indirect passage groove to the direct passage groove.
- the distributor of the invention passes from one communication position to another, being separated by non-communication positions. .
- the distributor of the invention since there are only two fluid paths in the document WO2001000521 A1, there are four in the distributor of the invention, since there are four passage grooves, a first to connect a tank to the pump, a second groove to connect the second tank to the pump and two other grooves to simultaneously connect the two tanks to the pump.
- the sealed contact is made cylinder in cylinder in the distributor of the invention at the level of the cylindrical sections engaged in the drums, and not disc on disc as in the distributor of document W02001000521 A1.
- the stopper can be made in one piece from a flexible material, in particular a thermosetting material, such as a silicone.
- a flexible material in particular a thermosetting material, such as a silicone.
- the elastic properties of such a material with high remanence ensure radial sealing over time, high compatibility with the formulations on the market and ease of rotation of the tip in the cap.
- the plug can form venting channels which connect the reservoirs of fluid product to the pump, advantageously through a venting passage formed in the endpiece.
- the fluid reservoirs may comprise a main reservoir and a secondary reservoir, the main reservoir comprising a neck in which the cap is removably mounted, the main reservoir supporting a shell, in which is arranged the secondary reservoir which is supported removably by the cap, so that the secondary tank can be removed from the hull.
- the secondary tank can thus be replaced or filled without opening the main tank.
- the main reservoir may comprise a reservoir body and a reservoir lid which are connected together in a removable manner, the reservoir lid forming the neck and supporting the shell, the reservoir lid advantageously forming a tube holder to which is connected a secondary dip tube connected to one of the connecting ducts of the cap.
- the spirit of the invention resides in the fact of designing a duo dispenser (or trio, or even more) whose dose selection (single or mixture) takes place by means of the rotation of a standard pump.
- the rotation generates a cylinder-in-cylinder contact, the tightness of which is optimal, but interrupted by passage grooves.
- Specific paths for mixing doses from the two reservoirs is another advantageous feature.
- Access to the secondary tank for replacement or filling, without opening the main tank, is another interesting aspect.

- the fluid product dispenser of the invention comprises two fluid product reservoirs, namely a main reservoir R1 and a secondary reservoir R2, each containing fluid products which may be identical, but preferably different. It can be seen in Figure 1 that the secondary reservoir R2 is arranged inside the main reservoir R1.
- the fluid dispenser of the invention also comprises a pump P which is provided with a push button B and a fixing ring F.
- This is a conventional pump comprising a pump body P1 having a symmetrical of revolution around an axis of revolution.
- the pump body defines an inlet pipe P2 internally forming a fluid product inlet P3.
- This inlet pipe P2 is arranged in a central axial manner and defines the single inlet of the pump, which communicates with a pump chamber through an inlet valve.
- the dispenser of the invention also comprises a cap 1 and an end piece 2, which constitute the heart of the invention.
- the dispenser also includes a fastening ring C which makes it possible to hold the cap 1 on the main tank R1.
- the main reservoir R1 is visible in Figures 1 and 2. It comprises a reservoir body R11, which can be in the form of a cup, a pot or a bottle, with an opening in the form of a an R112 threaded edge.
- the R11 tank body can be made of any transparent or opaque material, such as glass, plastic, metal, etc.
- the main tank R1 also includes a tank cover R12 which includes a threaded skirt R121 in threaded engagement with the threaded edge R112 of the tank body R11, advantageously crushing a neck gasket G1 between them to create an effective seal.
- the R12 cover also includes an R120 annular shoulder that extends radially inward from the R121 threaded skirt.
- An R122 lid neck extends upward from the inner periphery of the R120 tray.
- the R122 cover neck is advantageously threaded on the outside.
- the R12 reservoir cover also forms R125 snap tabs that extend down inside the R1 main reservoir from the inner periphery of the R120 tray.
- the tank cover R12 also forms a tube holder R123, in which is engaged a main dip tube R124 which extends into the main tank R1 to near its bottom.
- the inner wall of cover neck 122 is formed with a venting groove R126.
- a shell R3 is fixed to the tank cover R12 by snap-fastening at the level of the snap-fastening lugs R125.
- This shell R3 defines an internal volume in which the secondary tank R2 is received, as can be seen in FIG.
- the cap 1 of the invention is a part which is preferably made in one piece from a flexible material, in particular a thermosetting material such as a silicone.
- the stopper 1 is received in a sealed manner inside the neck of the cover R122.
- the cap 1 comprises sealing lips 19 intended to come into pressed contact sealed with the inner wall of the R122 lid neck.
- the stopper 1 is held in place using the fastening ring C which forms a sleeve C1 which is internally threaded. This C1 socket comes into threaded engagement with the thread of the R122 cover neck.
- the fastening ring C also comprises a flat flange C2 which makes it possible to press a sealing flange of the cap on the upper edge of the neck of the cover R122.
- Cap 1 is more visible in Figures 4a and 4b.
- the cap 1 defines a receiving housing 10 which globally has a central axial symmetry.
- This housing 10 is intended to receive part of the endpiece 1, as will be seen below.
- This housing 10 comprises a first sealing barrel 123 whose cylindricity is perfect.
- the housing 10 forms an upper shaft 11, the cylindricity of which is interrupted at the level of two axial passage grooves 111 and 112.
- the receiving housing 10 defines a second sealing barrel 12, the cylindricity of which is perfect.
- the housing 10 defines a lower barrel 13, the cylindricity of which is interrupted at the level of two axial passage grooves 131 and 132. It can be noted that the barrels 123, 11, 12 and 13 have decreasing diameters.
- Plug 1 also defines an axial retaining housing 14, which cooperates with end piece 2 as will be seen below.
- the plug 1 also defines a connecting duct 16 which connects the axial passage groove 111 to the outside of the plug.
- This connecting conduit comprises a radial conduit 161 which is extended by a vertical axial conduit 162 which directly connects the axial passage groove 111, as can be seen in FIG. 4a.
- the plug 1 also defines an axial central connecting conduit 151 which communicates directly with the axial passage grooves 131 and 132 of the second lower barrel 13. It will be seen below that the second passage groove 112 communicates with the first passage groove 111 through an annular channel 113 which is visible in Figure 6b.
- the cap 1 also defines venting channels which will be described in detail with reference to FIG. 8 below.
- the plug 1 also forms a fixing groove 152 which extends around a tube 15 in which the central axial connecting duct 151 is formed.
- This fixing groove 152 receives a ring R25 which is mounted in leaktight manner on the secondary reservoir R2, with a neck seal advantageously interposed.
- the ring R25 not only penetrates the fixing groove 152 but also penetrates inside the tube 15.
- This ring R25 also serves as a support or forms a secondary dip tube R26, visible in FIG. It can thus be said that the secondary tank R2, thanks to its ring R25, is directly connected to the plug 1, so as to communicate the interior of the secondary tank R2 with the central axial connecting channel 151 through the ring R25 and the R26 dip tube.
- the end piece 2 is a part which is preferably made in one piece from a polyolefin plastic material, such as PP or thermoplastic polyester, such as PBT or even polyacetal, such as POM.
- the endpiece 2 comprises a pump neck 21, which may have a completely conventional design for a container neck.
- the fixing ring F of the pump P comes into engagement with this pump neck 21 to achieve a fixing that is both solid and tight. Fastening can be achieved by snapping, crimping, screwing, etc.
- the end piece 2 also comprises an axial retaining skirt 22 which comes into engagement with the retaining housing 14 of the stopper. The skirt 2 can be inserted by force into the retaining housing 14, in particular when the stopper is made of a flexible material.
- an axial insertion path may be provided at the level of the retaining housing 14 to bring the skirt 22 into the housing 14.
- the end piece 2 is thus integral with the plug 1, while being able to turn on it -even with respect to the cap 1.
- the pump neck 21 is extended in its lower part by a sleeve 23 in which is engaged the inlet pipe P2 of the pump P in a sealed manner.
- the end piece 2 forms an interior space 20 which can communicate with the outside through two orifices 241 and 261. More precisely, the end piece 2 forms below the sleeve 23 a first upper cylindrical section 24 which is crossed through the upper orifice 241 which extends horizontally and radially.
- the orifice 241 opens onto the outside at the level of this first upper section 24.
- the endpiece 2 forms a cylindrical section 25 which comes into perfectly airtight engagement.
- the endpiece 2 forms a second lower cylindrical section 26 through which the second orifice 261 passes. It can thus be said that the outlet of the lower orifice 261 leads to the cylindrical section 26.
- the cylindrical sections 23, 24 and 25 have decreasing diameters. It can also be said that the orifices 241 and 261 are staggered or spaced apart axially and extend radially.
- the end piece 2 is oriented inside the cap 1 in such a way that the first upper orifice 241 is positioned at the level of the first upper passage groove 111, which extends directly by the axial duct 161, which itself is extended by the radial duct 162.
- the second lower orifice 261 it is obstructed by the cylindrical part of the lower shaft 13 of the cap 1, so that it cannot communicate with the central axial connecting conduit 151.
- the upper orifice 241 allows the inlet P3 of the pump P to communicate with the connecting conduit 16.
- the tip 2 also includes a slider 221, which is in the form of a tip, located in the vertical axial extension of the axial retaining skirt 221, that is to say outside the pump neck 21 .
- the end piece 2 also includes a venting passage 27 whose function will be given below with reference to Figure 8.
- the dispenser of the invention can be seen in the first dispensing position, in which the slider 221 is aligned with a first position indicator 11, located on the plate R120.
- This first dispensing position can be reached very simply by rotating the fixing ring F which drives the tip 2 in rotation in the cap 1 until the slider 221 is opposite the first indicator 11 .
- the tip 2 has a determined angular orientation relative to the cap 1, as can be seen in Figure 5b.
- the end piece 2 is oriented with respect to the cap 1 in the same way as in FIG. 4.
- the upper orifice 241 of the end piece 2 is aligned with the first upper passage groove 111 which communicates directly with the connecting conduit 16 which opens outside the cap 1 .
- the radial conduit 162 then communicates with the main dip tube R124 which extends inside the main tank R1.
- the second lower orifice 261 it is closed off by the second lower shaft 13 of the stopper 1 .
- the pump P only communicates with the main reservoir R1, through the interior space 20, the upper orifice 241, the first passage groove 111, the axial conduit 161, the first conduit radial 162 and main dip tube R124.
- cursor 221 is now aligned with a second position indicator I2.
- the movement of the cursor 221 is done in the same way as previously, that is to say by rotating the fixing ring F.
- the endpiece 2 is then positioned angularly with respect to the stopper, as shown in Figure 6b.
- the first upper orifice 241 is aligned with the second upper passage groove 112, which communicates with the first upper passage groove 111 via an annular channel R113 provided between the cap 1 and the end piece 2. From there, the communication of the fluid takes place as before through the axial conduit 161 and the radial conduit 162, which is connected to the main dip tube R124.
- the second lower orifice 261 is aligned with the second lower passage groove 132 which communicates directly with the central axial connecting conduit 151 to which the secondary dip tube R26 is connected.
- the pump communicates both with the main reservoir R1 and the secondary reservoir R2.
- the interior space 20 of the endpiece 2 will serve as a mixing chamber, in which the two fluid products coming from the two reservoirs will mix before entering the inlet P3 of the pump P.
- the axial channel 161 and the radial channel 162 are shown in dotted lines in Figure 6b, since they are offset from the plane of Figure 6b by 60°.
- FIG. 7a it can be seen that the cursor 221 is now aligned with the third position indicator I3, which is offset with respect to the two other indicators I1 and I2 by 120°.
- the tip 2 is then positioned angularly relative to the cap 1, as shown in Figure 7b.
- the first upper orifice 241 is closed off by the upper barrel 11, while the second lower orifice 261 is aligned with the first lower passage groove 131 which communicates directly with the central axial connecting conduit 151, which connects the tank secondary R2 via secondary dip tube R26.
- the pump communicates only with the secondary reservoir R2, via the internal space 20, the lower orifice 261, the first lower passage groove 131, the connecting conduit central axial 151, and the secondary dip tube R26.
- the rotation of the endpiece 2 in the cap 1 therefore makes it possible to define four different fluid paths, namely a first fluid path which connects the pump P to the main reservoir R1 through the first upper axial passage groove 111 in the first dispensing position (11), a second fluid path connecting the pump P to the secondary reservoir R2 through the first lower axial passage groove in the third dispensing position (I3), and two other fluid paths allowing the pump to connecting both the main reservoir R1 and the secondary reservoir R2 through the second upper axial passage groove 112 and through the second lower axial passage groove 132 in the second dispensing position (I2).
- the two upper axial passage grooves 111 and 112 which are offset at 120°, and the two lower axial passage grooves 131 and 132 are also offset at 120° relative to each other.
- this dispenser a user can switch from one dispensing position to another by rotating the fixing ring F relative to the main tank R1.
- the distributor also defines a whole network of channels and venting passages making it possible to connect the pump P to the two reservoirs R1 and R2.
- the pump P is preferably an atmospheric pump incorporating its own venting system.
- the venting path of the pump is opened.
- the pump body P1 is not in direct communication with the two reservoirs R1 and R2. This is why it is necessary to define a network of venting channels making it possible to connect the pump P with the interior of the two reservoirs R1 and R2.
- a venting space is defined inside the end piece 2.
- venting channels 181 and 182 can communicate with venting channels 181 and 182 via a venting passage 27 of the nozzle 2, which is in the form of an opening at the level where the pump neck 21 connects the sleeve 23.
- the venting channel 182 connects the secondary reservoir R2 and the venting channel 181 connects the main reservoir R1. More specifically, the venting channel 181 connects the main tank R1 through the venting groove R126 visible in Figure 1. As for the venting channel 182, it connects the secondary tank R2 via a venting hole R27 formed through the R25 fixing ring.
- the distributor of the invention allows easy filling of the secondary reservoir R2 without having access to the reservoir R1, although the secondary reservoir R2 is arranged inside the main reservoir R1. Indeed, after removal of the fixing ring C, it is possible to remove the plug 1 from the neck of the cover R122, which causes the extraction of the secondary tank R2 from the shell R3, given that the secondary tank R2 is directly fixed to cap 1. Once the reservoir R2 has been extracted from the shell R3, it can be easily detached from cap 1 and replaced by a new or filled reservoir. The user then just has to put the tank R2 back in place in the shell R3 by pushing the cap 1 into the neck of the cover R122. Putting the fixing ring C back in place completes the replacement or filling operation.
- the invention there is a dispenser with two tanks and a single standard pump, which makes it possible to easily switch from one tank to the other or even to both tanks at the same time.
- the end piece 2 of the invention is an essential constituent element which makes it possible both to manage the different fluid paths, but above all the use of a standard pump.
- the description has been made with reference to a dispenser having three different dispensing positions, but it is also possible to limit the number of dispensing to two, by removing the second dispensing position, in which the pump communicates with the two reservoirs at the same time. time.
- the upper shaft 11 comprises only one axial passage groove and the second barrel 13 comprises only one axial passage groove 131.
