Description

Title of the invention: Fluid product dispenser

[0001] The present invention relates to a fluid product dispenser comprising a dispensing element (pump or valve) connected to a main reservoir containing a first fluid product. The dispensing element communicates with a main axial outlet orifice that moves along an actuating axis. The dispenser also comprises several secondary reservoirs containing a second fluid product, each having a movable wall, as well as a plunger that can be moved along the actuating axis, thereby driving the main outlet orifice. Such dispensers are used in the cosmetics, perfumery, and pharmaceutical industries.

[0002] In the prior art, document WO2012113749A1, which describes several distributors of this type, is already known. According to one embodiment of this document, the distributor comprises a rotating annular barrel that forms several reservoirs. The outer periphery of this barrel is accessible so as to allow it to be rotated. The rotating barrel is removably mounted under a plunger that moves axially but is prevented from rotating. This is because the plunger includes a central orifice for the valve and an offset orifice, which is common to all the reservoirs of the rotating barrel. Each reservoir must be rotated by the barrel over a fixed pad to press it against this pad and discharge its contents through the offset orifice, which must therefore also be positioned above the pad. This implies that the plunger must be oriented angularly so that its offset orifice is axially aligned with the fixed pad.This document does not describe how the pusher and barrel are oriented relative to the fixed post.

[0003] The present invention aims to improve this dispenser, both in terms of its design and its use. The risk of leakage or residue of fluid product at the offset orifice must be eliminated. The rotation of the barrel must be easier. The stability of the barrel must be ensured. Replacing the barrel must be simpler.

[0004] To this end, the present invention proposes a fluid product dispenser comprising: - a distribution unit, such as a pump or a valve, connected to a main reservoir containing a first fluid product, the distribution unit communicating with a main axial outlet orifice which moves along an actuation axis, and - several secondary reservoirs containing a second fluid product and each having a movable wall, - a pusher that can be moved along the actuation axis, driving the main outlet orifice, characterized in that the pusher defines as many secondary outlet ports as there are secondary reservoirs, the secondary outlet ports being distinct from the main axial outlet port, each secondary outlet port being supplied by a secondary reservoir in response to the displacement of its movable wall caused by the movement of the pusher along the actuation axis.

[0005] Thus, each secondary reservoir feeds its own secondary outlet port, so that there is no relative movement, in particular rotation, between the secondary reservoirs and the pusher.

[0006] According to a particularly interesting aspect of the invention, the plunger and the secondary reservoirs form a removable cartridge unit, which is rotatably mounted around the main axial outlet and the actuating axis. Whereas the plunger and barrel of document WO2012113749A1 are two separate parts that can be separated and rotate relative to each other, the plunger and the secondary reservoirs of the invention are fixed and thus form a single unit.

[0007] According to an advantageous feature, the removable cartridge element is elastically ejected from the distribution member after a rotational movement through a predetermined angle, advantageously on the order of 360°. In practice, the user axially presses the cartridge element against elastic means on the distribution member, then rotates it through a small angle, for example, on the order of 10°. The cartridge element is then connected but can rotate on its own axis. The user can then rotate it until it reaches the end of its travel in a retracted position where it is released and ejected by the elastic means.

[0008] According to another feature of the invention, the movable wall of each secondary reservoir successively engages with a fixed pressing pad under the action of the plunger. Advantageously, the distributor may include angular positioning means for fixing the angular position of each secondary reservoir in turn by rotating it above the fixed pressing pad. Thus, the user does not have to search by trial and error for the precise angular position of the cartridge unit. When rotating it, the user perceives stable positions that correspond to the successive axial alignments of the secondary reservoirs above the fixed pressing pad.

[0009] According to one embodiment of the invention, the main outlet orifice is surrounded by a main recovery area integral with the distribution element, the secondary outlet orifices are surrounded by a secondary recovery area formed by the plunger, the two main and secondary areas being connected flush. Preferably, the main area is central and the secondary area surrounds the main area. Thus, the secondary area can be part of a removable cartridge unit, while the main area remains in place on the distribution element. distribution. The secondary range is therefore reported around the primary range without creating a major discontinuity between them. The cartridge entity may have an overall configuration similar to a donut (toric-shaped doughnut).

[0010] According to another embodiment of the invention, the pusher defines both the main axial outlet orifice and the secondary outlet orifices, surrounded by a single common recovery area. The cartridge entity may have an overall configuration similar to a puck.

[0011] According to another aspect of the invention, the pusher can form internal housings in which secondary reservoirs are received in the form of crushable capsules filled with a second fluid product, each internal housing advantageously being provided with a drilling needle that leads to the secondary outlet orifice. Alternatively, the pusher can form internal compartments sealed by deformable membranes acting as movable walls. Advantageously, the deformable membrane can be chosen from a foldable membrane and a stretchable membrane.

[0012] According to a fully developed embodiment, the distribution member comprises an actuating rod which is movable along the actuating axis, this actuating rod being capped by a plate which is movable axially, but blocked in rotation, the plate forming a central head in contact with the actuating rod and an offset passage window for a fixed pressing pad which blocks the plate in rotation, the pusher being mounted removably on the plate and rotatable around the central head, so as to be able to position in turn a secondary reservoir above the fixed pressing pad, which will crush the secondary reservoir and thus discharge the second fluid product through the secondary outlet orifice, at each actuation of the pusher, which simultaneously generates the actuation of the distribution member, which will discharge the first fluid product through the main axial outlet orifice.The central head can form the main axial outlet and a main recovery area that surrounds the main axial outlet. Alternatively, the central head can be covered by the plunger which forms both the main axial outlet and the secondary outlets, surrounded by a single common recovery area.

[0013] The spirit of the present invention lies in assigning an outlet orifice to each secondary reservoir. The combination of the plunger that forms the secondary outlet orifices and the secondary reservoirs in the form of a replaceable, removable cartridge or refill is a particularly advantageous feature of the invention. The ejection and angular positioning means for the cartridge are very practical and offer great ease of use. The cartridge forms the secondary outlet orifices and can also form the main axial outlet orifice. The The tray allows the cartridge to be received with greater stability, especially when the tray is axially guided.

[0014] The invention will now be described more fully with reference to the accompanying drawings, giving, by way of non-limiting examples, two embodiments of the invention.

[0027] [Fig. 10] The [Fig. 10] is a perspective view from below of a cartridge according to one embodiment of the invention.

[0028] Reference will first be made to Figures 1, 2, and 3 to describe the fluid product dispenser according to the first embodiment of the invention. This dispenser of the invention comprises, firstly, a fluid product reservoir R, in which a fluid product, such as a cream, gel, lotion, serum, etc., is stored. This reservoir R includes a neck RI for mounting a dispensing element P, a guide sleeve R2 extending around the neck RI, and a pressing pad R3 extending axially upwards in the annular space defined between the neck RI and the guide sleeve R2. The reservoir R can be made of any material, such as plastic or metal.

[0029] The distribution element P may be a pump or a valve, comprising a body PI defining a retaining flange P2 which engages in the neck RL. The distribution element P also comprises an actuating rod P3 which is axially movable in a reciprocating motion within the body PI to deliver fluid product in a controlled or uncontrolled manner. This is a perfectly standard design for a pump or valve in the cosmetics, perfumery, or pharmaceutical industries. Since the distribution element P is not critical to the present invention, it will not be described in further detail.

[0030] The distributor also includes a plate 3, which is mounted on the free end of the actuating rod P3 of the distribution member P. The plate 3 is therefore axially movable with the actuating rod P3. The plate 3 includes a head 31 which fits over the actuating rod P3. The head 31 includes for this purpose a sleeve 33 which is engaged by force and / or by snap-fit ​​onto the free end of the actuating rod P3. Downstream of the actuating rod P3, the head 31 forms a passage hole 32, through which the fluid product discharged by the distribution member P will pass. The head 31 surrounds the actuating rod P3 and even extends around the neck RI with a skirt 34, which will participate in guiding the plate 3 on the reservoir R. The plate 3 also includes an annular flange 35 which extends radially outwards from the head 31.This annular flange 35 forms an axial passage window 36, into which the pressing pin R3 of the reservoir R is engaged. The flange 35 also forms an elastic tab 37 whose function is to create the sensation of passing over radial resistance points during the indexing of the plunger. It eliminates radial rotational play and provides a certain axial retention to prevent the removable cartridge from being lost while it is being inserted. Finally, on its outer periphery, the plate 3 forms a guide ring 38, which is engaged inside the guide sleeve R2 of the reservoir R, so as to guide the plate axially in a stable manner.

[0031] Thus, an axial support on the head 31a has the effect of pushing the actuating rod P3 into the body PI of the distribution member P, of sliding the skirt 34 around the neck RI, of sliding the pressing stud R3 in the axial passage window 36 and of sliding the ring 38 inside the sleeve R2 of the reservoir R. The fluid product discharged by the distribution member P will pass through the passage hole 32 of the head 31.

[0032] The distributor of the invention also includes a pusher 1 which is mounted on the plate 3, so that it also moves axially back and forth with the plate 3 and the actuating rod P3. This pusher 1 includes a recovery zone 10, which preferably has a slightly curved shape. This recovery zone 10 is first pierced with a main axial or central outlet 11, which is aligned with the through hole 32 in the head 31 of the plate 3. Thus, the fluid product from the distribution member P is forced through the actuating rod P3, the through hole 32, and the main orifice 11 to reach the recovery zone 10. In addition to the main orifice 11, the recovery zone 10 is also pierced with several secondary outlet ports 12, which extend around the main port 11. Upstream of the secondary ports 12, the pusher 1 forms drilling points 13, the function of which will be described below. These drilling points 13 protrude into internal recesses 15, which are defined by tubes 14 extending downwards from the recovery area 10. The tubes 14 may be separated from each other or, conversely, joined together, so as to form a ring. According to the invention, secondary reservoirs, in the form of crushable capsules 2, are received respectively in the internal recesses 15. These crushable capsules 2 may be in the form of small eggs comprising a flexible outer shell filled with a fluid product, which may be identical, but preferably different, from that of the reservoir R.The crushable capsule 2 includes a lower wall 21 which is positioned at the lower opening of the compartment 15 so as to be accessible. Conversely, its upper wall makes light contact with the piercing needle 13. To retain the crushable capsules 2 in their respective compartments 15, sufficient friction or a reduced opening may be provided, as is the case in Figures 1 and 2. On its outer periphery, the pusher 1 includes a gripping ring 16, which may be provided with projecting profiles to facilitate its grip. The free lower edge of the gripping ring 16 may come into contact with the guide ring 38 of the plate 3.

[0033] The recesses 15 are formed above the annular flange 35, so that it is possible to position a recess 15 axially in line with the pressing pad R3, as can be seen in Figures 1 and 2. The free end of the pressing pad R3 is located near the lower wall 21 of the crushable capsule 2 received in the recess 15. The elastic tab 37 of the plate 3 is engaged in the space formed between the tubes 14 and the gripping ring 16 to hold the pusher 1 on the plate 3, but also to angularly index the pusher 1 on the plate 3 by passing through hard points, which guide the user during use of the product. More specifically, the flexible tab 37 comprises an anchoring blade 371 and a free blade 372.The anchoring blade 371 engages with the gripping ring 16 and the free blade 372 engages, for example by snapping it into place, with the tubes 14 (separate or joined) to create the hard or stable points, each corresponding to the axial alignment of a secondary reservoir or capsule 2 above the pressing pad R3. The elastic tab 37 therefore fulfills an angular positioning function to guarantee the successive axial alignment of the secondary reservoirs 2 above the pressing pad R3.

[0034] The pusher 1, with its secondary reservoirs 2 in the form of crushable capsules, can be permanently mounted on the plate 3, but preferably the pusher 1 and its crushable capsules 2 are removably mounted on the tray 3, forming a removable cartridge unit, which can also be referred to as a refill. This removable cartridge unit is more clearly visible in [Fig. 3], which shows the cartridge unit Cl ready to be placed back onto the tray 3. Once in place, it is in the starting position shown in [Fig. 1]. A user can then press the pusher 1, for example on the outer edge of the recovery area 10, to move it downwards towards the reservoir R. This depressing of the pusher 1 causes the tray 3 to lower and pushes the actuating rod P3 into the body PI of the dispensing element P.The fluid product from the dispensing element P is thus forced through the actuating rod P3, the passage hole 32, and the main orifice 11, spreading onto the recovery area 10, as shown in [Fig. 2]. Simultaneously, the pressing pad 3 enters the housing 15 and engages with the lower wall 21 of the crushable capsule 2. The capsule is thus pushed firmly against the piercing needle 13, which pierces its flexible outer shell. The fluid product it contains can then escape through the secondary orifice 12 and spread onto the recovery area 10, alongside, but eccentrically relative to, the fluid product from the dispensing element P. The user can then mix the two fluid products on the recovery area 10 before applying the mixture to the target surface, which can be skin, nails, hair, etc.

[0035] Since the dispenser comprises only one pressing pad R3, only one secondary reservoir 2 is activated and emptied each time the pusher 1 is actuation. To renew the dispensing of fluid products, the pusher 1 must be rotated on the plate 3 so as to position another secondary reservoir 2 in axial alignment with the pressing pad R3. The actuation operation can then be repeated. For example, by providing eight secondary reservoirs 2 distributed equally around the main orifice 11, the user will have to rotate the pusher 1 around the X-axis by an angle of 45° to move from one secondary reservoir 2 to the next. As will be seen below, the dispenser can be equipped with angular positioning means to fix the angular position of the pusher 1 relative to the pressing pad R3, so that each secondary reservoir 2 is successively positioned in alignment above the pressing pad R3.

[0036] It can be noted that in this first embodiment of the invention, the plunger 1 forms both the main orifice 11 and the secondary outlet orifices 12, at the level of a single common recovery area 10, on which the mixing of the fluid products can be carried out. The cartridge entity Cl, consisting of the plunger and its secondary reservoirs 2, is then in the form of a disc or a puck, as can be seen in [Fig. 3].

[0037] Reference will now be made to Figures 4, 5, and 6 to describe a second embodiment of a fluid product dispenser of the invention. The dispensing member P may be strictly identical or similar to that of the first embodiment, with a body PI and an actuating rod P3. The dispensing member P is received in a neck Fl which is formed by a retaining ring F. This ring also includes a threaded skirt FO, a guide bushing F2, and a pressing stud F3. The architecture of this retaining ring F is comparable to that of the reservoir R of the first embodiment shown in Figures 1 to 3.

[0038] The plate 3' includes a head 31' which is also mounted on the free end of the actuating rod P3. The head 31' defines a main axial or central outlet 32', as well as a main recovery area 30' which extends around the main outlet 32'. The plate 3' also includes an annular flange 35' which is pierced by an axial through-hole 36' in which the pressing pin F3 is engaged, just as in the first embodiment of the invention. The plate 3' includes a guide ring 38' which is engaged inside the guide sleeve F2 of the retaining ring F, just as in the first embodiment of the invention.

[0039] The pusher 1' is mounted on the plate 3' around the head 31'. For this purpose, the pusher 1' defines a central passage opening 11', in which the head 31' is engaged. The pusher 1' forms a secondary recovery area 10' which extends all around the main recovery area 30', preferably in a contiguous and flush manner, so as to avoid any deposit or residue of fluid product at the junction of the two areas. The secondary recovery area 10' is formed with secondary outlet ports 12' which communicate with secondary reservoirs 2' located below the secondary recovery area 10'.

[0040] Referring to [Fig. 6], it can be seen that the plunger 1' forms internal compartments 15' around the central passage opening 11'. These internal compartments 15' are sealed by deformable membranes 21' formed as a single unit by a ring 22'. As can be understood from [Fig. 6], the ring 22' with its deformable membranes 21' is attached inside the plunger 1' and fixed in a hermetic manner, for example by welding or bonding. The secondary reservoirs 2,' thus formed by the compartments 15' and the deformable membranes 21' contain a fluid product which is preferably different from that dispensed by the dispensing member P. In this embodiment, the deformable membrane 21' is a foldable membrane, as will be seen below.

[0041] The pusher 1' is mounted axially on the plate 3' by passing the head 31' through the central opening 11'. The pusher 1' can be permanently mounted on the plate 3', but preferably the pusher 1' with its ring of The 22' membrane constitutes a removable cartridge entity C2, which the user can remove from the 3' tray once the 2' secondary reservoirs have been emptied.

[0042] Just as in the first embodiment of the invention, it is possible to provide angular positioning means in order to axially align each reservoir 2' above the pressing pad F3.

[0043] The operation of this second distributor of the invention is strictly identical to that of the first embodiment shown in Figures 1 to 3. The user can press the pusher 1', for example, at its outer periphery. The plate 3' is driven downwards, which has the effect of pushing the actuating rod P3 into the body PI of the distribution member P. Fluid product is then forced through the actuating rod P3 and the main orifice 32', so as to spread over the main recovery area 30'. Simultaneously, the deformable diaphragm 21' is moved by the pressing pad F3, so as to force the contents of the secondary reservoir 2' through the secondary outlet orifice 12'. The fluid product is then present at the secondary recovery area 10', which surrounds the central recovery area 30'. The user can mix the two products before applying them to the desired target surface.

[0044] In this second embodiment of the invention, it can be noted that the removable cartridge entity C2 is in the form of a washer, or more precisely a toroidal donut, which is known as a "donut".

[0045] Figures 7a and 7b illustrate the behavior of the deformable diaphragm 21' when subjected to pressure by the pressing pin F3. In [Fig. 7a], the distributor is at rest, with the pressing pin F3 engaged in the passage window 36', but still out of contact with the diaphragm 21'. It can be seen that the diaphragm 21' forms a kind of cup oriented downwards towards the pressing pin F3. In [Fig. 7b], the state of the diaphragm 21' is shown after the pressing action of the pin F3. It can be seen that the cup formed by the diaphragm 21' has been literally folded back so as to come into contact with the internal walls of the compartment 15'. The volume of the secondary reservoir is then close to zero. It can be understood that the diaphragm 21' has been deformed by a folding or turning action, without significant stretching.Thanks to this 21' rollable membrane, it is possible to create large capacity 2' secondary tanks, while ensuring their almost total emptying without risk of membrane rupture.

[0046] According to one embodiment, the rollable membrane 21' can simply be replaced by a stretchable membrane 21”, which closes the compartments 15' so as to form the secondary reservoirs 2'. This stretchable membrane 21' can be in the form of a flat film, as can be seen in [Fig.8a]. After action of the F3 pressing pad, this 21' stretch film is deformed inside the 15' compartment, so as to get closer to its internal walls, thus reducing the volume of the tank considerably.

[0047] Figures 9 and 10 are intended to illustrate removable connection means and angular positioning means between a 3” plate and a cartridge entity C3. These removable connection means and angular positioning means can easily be implemented in the second embodiment of the invention of Figures 4 to 6 and also in the first embodiment of Figures 1 to 3 with some adaptations, replacing the elastic tab 37, which also fulfills removable connection and angular positioning functions.

[0048] In [Fig. 9], it can be seen that the plate 3” also includes a head 31” defining a central or axial main outlet 32', as in the second embodiment of the invention. This main outlet 32' is surrounded by a main recovery area 30', as in the second embodiment. However, it can be noted that the head 31” includes several tabs 311 that project radially outwards from the peripheral wall of the head 31”. In [Fig. 9], four tabs 311 can be seen that are distributed substantially equidistantly around the periphery of the head. The tabs 311 do not all have the same width so as to form a kind of key that can be inserted with a specific angular orientation. The plate 3” also includes an axial passage window 36', in which the pressure pad F3 is engaged.Outside the window 36', the plate 3' includes three teeth 312 which are mounted on elastic tabs 313. Thus, these teeth 312 can perform an axial displacement by bending the tabs 313.

[0049] In [Fig. 10], a removable cartridge entity C3 is seen comprising a pusher 1” associated with a ring 22' forming deformable membranes 21'. Inside the ring 22', the pusher 1” forms four cylinder segments 17 separated by axial slots 171 of distinct widths. These cylinder segments 17 constitute a kind of lock designed to cooperate with the key of the 3” plate, which is formed by the tabs 311 of different widths. More precisely, the tabs 311 can be inserted into the slots 171 separating the cylinder segments 17, but only at a specific angular position, which is dictated by the widths of the tabs 311 and the slots 171 separating the cylinder segments 17. Once fully engaged between the cylinder segments, the tabs 311 can engage under the cylinder segments 17 in such a way as to allow the rotation of the cartridge entity C3 on the 3” plate.The rotation of the cartridge entity C3 is thus possible until the tabs 311 reach their starting position opposite their respective slots 171. From this position, the tabs 311 can. new to be removed through the slots 171 separating the cylinder segments 17. In this way, the cartridge entity C3 is fixed to the plate 3” over a complete turn, i.e. 360°.

[0050] Still in [Fig. 10], it can be seen that the pusher 1” forms crenellated profiles around the ring 22'. These crenellated profiles comprise peaks 18 and troughs 19 separated by slopes 189. There are as many peaks 18, troughs 19, and slopes 189 as there are secondary reservoirs, and therefore deformable membranes 21'. These crenellated paths are intended to cooperate with the teeth 312 mounted on the flexible tabs 313. Rotation of the cartridge entity C3 on the plate 3” is possible by deforming the tabs 313, so as to bring the teeth 312 onto the peaks 18, and then into an adjacent trough 19. In this way, the angular position of each deformable membrane 21' in alignment with the pressure pad F3 is ensured. After each actuation of the cartridge entity C3, the user rotates the cartridge entity C3, so as to bring the teeth 312 from one hollow 19 to the next hollow by way of a vertex 18.When all the secondary reservoirs have been emptied, a final rotation brings the tabs 311 to the level of their respective slots 171 and the teeth 312 will then eject the cartridge entity C3, because the teeth 312 are then positioned at a peak 18, which creates the deformation of the flexible tabs 313. The serrated paths also include steep slopes 198, preventing the rotation of the cartridge entity C3 in the counterclockwise direction.

[0051] Removable connection means therefore allow the cartridge entity to be connected to the plate 3” over a complete turn, at the end of which the cartridge entity C3 is ejected by the teeth 312 elastically stressed by the lugs 313.

[0052] Angular positioning means allow each secondary tank to be positioned precisely above the pressing pad F3.

[0053] Thanks to the invention, a rotary push-button distributor is available, advantageously removable, which includes as many secondary outlet ports as there are secondary reservoirs. The plate mounted on the actuating rod of the distribution element allows for stable reception and guided axial movement.

A distributor according to any one of the preceding claims, wherein the distribution member (P) comprises an actuating rod (P3) which is movable about the actuating axis (X), this actuating rod (P3) being capped by a plate (3; 3'; 3") which is axially movable but rotationally blocked, the plate (3; 3'; 3") forming a central head (31; 31'; 31") engaging with the actuating rod (P3) and an offset passage window (36; 36') for a fixed pressing pin (R3; F3) which prevents the plate (3; 3'; 3") from rotating, the pusher (1; 1'; 1") being removably mounted on the plate (3; 3'; 3") and rotatable about the central head (31; 31'; 31"), so as to be able to position at in turn a secondary reservoir (2; 2') above the fixed pressing block (R3; F3), which will crush the secondary reservoir (2; 2') and thus expel the second fluid product through the secondary outlet orifice (12; 12'), at each actuation of the pusher (1; 1'; 1"), which simultaneously generates the actuation of the distribution member (P), which will expel the first fluid product through the main axial outlet orifice (11; 32').

13. Distributor according to claim 12, wherein the central head (31'; 31") forms the main axial outlet orifice (32') and a main recovery range (30') which surrounds the main axial outlet orifice (32').

14. Distributor according to claim 12, wherein the central head (31) is covered by the plunger (1) which forms both the main axial outlet orifice (11) and the secondary outlet orifices (12), surrounded by a single common recovery area (10).
