Definitions
- the present invention relates to a fluid product application device for applying a fluid product to a target surface using an applicator.
- the transfer of fluid product from the applicator which is an integral part of the fluid product dispenser, takes place by contact of the applicator with the target surface, which may for example be the skin of a user.
- the fluid product can be of low viscosity, such as perfume, but preferably it will be a more viscous fluid product, such as oil or serum.
- document US10806232B2 describes a fluid applicator device comprising a base part mounted on a reservoir of fluid product, the base part comprising a dip tube connecting a cup provided with a piston lip .
- the applicator device also comprises a removable member removably mounted along a sliding axis on the base part.
- the removable member comprises a tube or pipette capable of sliding along a sliding axis in a sealed manner against the piston lip over a sealed axial stroke and an applicator capable of retaining a dose of fluid product coming from the reservoir by suction generated by the sliding tightness of the tubing against the piston lip: the applicator being formed in the tubing.
- the fluid product would thus be injected into the applicator through the dip tube.
- the removable member further comprises a teat communicating with the applicator and the dip tube.
- a fluid product applicator comprising:
- a base part mounted on a main reservoir of fluid product the base part comprising a dip tube connecting a cup provided with a piston lip, and
- the removable member comprising a pipe capable of sliding in a sealed manner against the piston lip over a sealed axial stroke and an applicator capable of retaining a dose of fluid product injected by suction generated by the sealed sliding of the tubing against the piston lip, the applicator being formed in the tubing, the fluid product being injected into the applicator through the plunger tube, the removable member further comprising a teat communicating with the applicator and the dip tube, characterized in that the nipple internally defines a secondary reservoir of fluid product to supply the applicator with fluid product.
- the removable member has its own reservoir, once it has been removed from the base part. This offers greater autonomy to the applicator, which can be fed from the secondary tank by crushing the teat. This new function conferred on the pacifier clearly stands out from the overall teaching of document US10806232B2.
- the pacifier defines a useful actuation volume which corresponds to the difference between its maximum volume at rest and its minimum volume after maximum crushing, this useful volume being greater than the volume of the applicator, by approximately 2 to 4 times the minimum, about 4 to 5 times advantageously, and more than 5 times preferably.
- the removable member can have a reserve of refill doses for the applicator. The user can squeeze constantly and gently press the teat to feed the applicator continuously.
- the removable member defines an axial height Ho and the applicator defines an axial height Ha, Ha preferably being at most equal to half of Ho.
- the applicator defines an axial height Ha and the teat defines an axial height Ht, Ha being advantageously at most equal to and preferably less than Ht.
- the applicator of the invention is short compared to a conventional applicator, such as that of US10806232B2, which can be described as an elongated pipette, the length of which corresponds approximately to twice that of the teat. Because the user grasps and manipulates the removable member by the teat, the precision of application decreases with the lengthening of the teat. However, by reducing the length of the applicator, the precision of application is certainly increased, but its capacity is reduced and therefore the quantity of fluid product to be applied is reduced.
- the invention confers a secondary reservoir function on the teat, which will supply the "short" applicator during the application phases, during which the removable member is of course separated from the main reservoir. .
- the reservoir integrated into the teat makes it possible to compensate for the disadvantage associated with the reduced length of the applicator, which offers good precision of application.
- an extension tube can extend from the bottom of the bucket in the extension of the dip tube in the direction of the teat, when the removable member is in place on the base part.
- the extension tube comes close to or even in contact with the teat, when the removable member is in place on the base part.
- the pacifier comprises an inlet defining a seat, the extension tube comprising a free upper end which can come into sealing contact with the seat of the pacifier.
- the fluid present in the applicator around the extension tube can be considered as a dead volume, given that it is located in a cul-de-sac closed by the piston lip.
- the pacifier defines a useful actuation volume which corresponds to the difference between its maximum volume at rest and its minimum volume after crushing, this useful volume being greater than the combined volumes of the dip tube and the extension tube, about 2 to 4 times minimum, about 4 to 5 times advantageously, and more than 5 times preferably.
- the extension tube can occupy more than 50% of the volume of the applicator, advantageously more than 75% of the volume of the applicator, and preferably more than 90%.
- Full occupancy is ideal, but only in theory. An occupancy above 90% is already very satisfactory.
- the extension tube can be formed integrally with the bucket or with the dip tube. It is even possible to envisage the dip tube with one-piece extension tube being slidably mounted in the cup to ensure that the extension tube comes into good contact with the inlet of the teat.
- the present invention also defines a method for loading a fluid product applicator as defined above, comprising the following successive steps: a) crushing the nipple, then releasing it, to suck fluid product from the main reservoir into the secondary reservoir of the teat, and b) removing the removable member from the base part to fill the applicator by suction of fluid product from the main reservoir and/or the secondary reservoir.
- a) crushing the nipple, then releasing it, to suck fluid product from the main reservoir into the secondary reservoir of the teat and b) removing the removable member from the base part to fill the applicator by suction of fluid product from the main reservoir and/or the secondary reservoir.
- the spirit of the invention resides in the fact of using the teat as a reservoir of fluid product which will supply the applicator during the application of the fluid product, and not of suction means for filling the applicator.
- Figure 1 is an exploded vertical cross-sectional view through a fluid product application device according to a first non-limiting embodiment of the invention
- Figure 2 is an enlarged view of the application device of Figure 1 in the assembled state
- FIGS 3 and 4 are respectively represent two other embodiments of the invention.
- Va is the volume written inside the applicator: this volume Va can be filled with fluid product.
- the fluid product application dispenser of the invention comprises a main reservoir of fluid product R, which can be of any kind and of any shape. It includes an opening, usually in the form of an R1 pass.
- the main tank R is not a critical element for the present invention.
- the fluid product application device also comprises two main constituent elements, namely a fixed base part 1 and a removable member 2.
- the base part 1 is intended to be mounted in a fixed and leaktight manner on the neck R1 of the main tank R.
- the removable member 2 is removably mounted on the base part 1 .
- the base part 1 comprises a fixing skirt 11 intended to cooperate with the main tank R to fix the base part 1 on the main tank R in a stable and leaktight manner.
- the fixing skirt 11 can for example comprise heads of attachment intended to come into engagement with an appropriate profile formed by the neck R1 of the main tank R. It is also possible to envisage forming the fixing skirt 11 with an internal thread intended to cooperate with an external thread formed by the neck R1 of the main tank A. Again, the type of hooking technique to mount the fixing skirt
- the fixed base part 1 also comprises an annular plate 12 which can optionally be used to crush a neck joint J on the upper annular edge of the neck R1 of the main reservoir R.
- the base part 1 also forms a sleeve 13 which is internally threaded .
- the base part 1 can be provided with an outer casing 14 which surrounds the skirt 11 and the sleeve 13 and comes into contact with the main reservoir R.
- the base part 1 also forms a cup 15 which is connected to the plate
- the cup 15 defines a wide upper opening 151 and a small lower orifice 152. At its upper opening 151, the cup 15 forms or is provided with a lip of piston 16, which advantageously points downward and inward. At its lower orifice 152, the cup 15 forms or is provided with a dip tube 17, which extends downwards in the main reservoir R to its bottom. Still at its lower orifice 152, the cup 15 forms or is provided with an extension tube 18, which extends upwards inside the cup 15 to its upper opening 151, and even to the -of the. This tube extension 18 extends substantially or perfectly in the extension and alignment of the dip tube 17.
- the extension tube 18 is made in one piece with the bucket 15, but it could also be formed in one piece with the tube plunger 17. In this case, the extension tube 18 would appear as an upper portion of the plunger tube 17 which extends into the cup 15. It can be seen that the lower orifice 152 forms the junction between the plunger tube 17 and extension tube 18.
- a bucket volume Vg is defined in the bucket around the extension tube 18, which defines a volume Vte.
- the dip tube 17 it defines a volume Vtp.
- the movable member 2 essentially comprises two component parts, namely an applicator element A and a teat T which are fixedly connected to each other.
- the applicator element A is preferably made of a hard material
- the pacifier T is made of a flexible material, since it is intended to be crushed by the user, for example between his thumb and his index finger.
- the applicator element A comprises a tube A1 which internally defines an applicator A2 of volume Va and externally an external sliding surface A3, intended to come into sealed sliding contact with the piston lip 16.
- the tube A1 extends axially towards the bottom from the inner periphery of an annular flange A4, which thus forms a projecting flange at the upper end of the tubing A1.
- the outer periphery of the flange A4 is connected to a ring A5 which is externally threaded and which is adapted to come into threaded engagement with the threaded sleeve 13.
- the ring A5 forms a housing A6, the function of which will be given below.
- the ring A5 is surrounded by a grip ring A 7.
- the applicator element A is provided with a hoop A8 which forms a re-entrant flap A86 which closes housing A6.
- the teat T comprises an anchoring heel T1 which forms an entrance T2.
- the anchor heel T 1 is received in the ring A5 and comes into abutment on the flange A4.
- the T2 inlet may narrow the upper opening of the A1 tubing.
- the heel T1 forms an A6 fixing collar which is received in the A6 housing and held in place by the re-entrant flap A86 of the hoop A8.
- the teat T forms a bulb T3, which has the function of being crushed between the fingers of the user.
- This bulb defines a peripheral wall A4 and an upper wall A5.
- the user will exert his digital pressure on opposite faces of the peripheral wall A5.
- the crushed state is shown in Figure 2 in dotted lines.
- the teat T performs the function of a secondary reservoir Tr, whose useful actuation or suction volume Vu corresponds to the difference between the maximum volume VM of the teat in the state of rest ( shown in solid lines in Figure 2) and the minimum volume Vm of the teat in the completely crushed state (shown in dotted lines in Figure 2).
- the VM/Vm ratio is preferably greater than 1 ⁇ 2.
- the removable member 2 is separated or removed from the base part 1 mounted on the reservoir R.
- the removable member 2 is in place on the base part 1, with the tubing A1 engaged in the cup 15 around the extension tube 18 and the threaded ring A5 in engagement with the threaded sleeve 13.
- the external sliding surface A3 is in leaktight contact with the piston lip 16 and the free end of the extension tube 18 is in sealed contact with the inlet T2 of the teat T, which thus forms a seat: the extension tube 18 is therefore directly connected to the teat T by shunting the cup 15. It is thus possible to define a closed volume Vc which extends on either side of the tubing A1, from the piston lip 16 to the inlet T2 closed off by the extension tube 18.
- Vc is equal to Va minus the volume of the constituent material of the tubing A1 and of the extension tube 18 minus the Vte. Furthermore, it can be noted that the extension tube 18 occupies more than 50% of the volume Va of the applicator A2, advantageously more than 75% and preferably around 90%.
- Vu > Vte + Vtp.
- Vu > 5 (Vte + Vtp).
- Vu 600 mm 3
- Vtp 90 mm 3
- Vte 30 mm 3
- Va 120 mm 3 .
- the removable member 2 defines an axial height Ho and the tubing A2 or the applicator A2 defines an axial height Ha: Ha ⁇ Ho/2.
- the teat T defines an axial height Ht: Ht>Ha.
- the applicator device operates as follows, starting from the assembled state of FIG. 2, in which the teat T, the dip tube 17 and the extension tube 18 are empty of fluid product.
- the user begins by grasping the pacifier at its T4 peripheral wall and exerting pressure with his thumb and index finger.
- the air present in the teat T, the dip tube 17 and the extension tube 18 is then expelled into the reservoir R.
- the user then releases the pressure on the teat T, which will return to its initial position of rest of the made of its elastic shape memory.
- the fluid product is sucked into the teat T through the dip tube 17 and the extension tube 18.
- the teat T is then partially filled with fluid product. This is possible since Vu is greater than Vte + Vtp, and preferably much greater, up to more than 5 times. And since Vu is greater than Va, and preferably much greater, up to more than 5 times, the secondary reservoir Tr of the teat T is filled with a quantity of fluid product which corresponds to several doses of the applicator A2.
- a second step the user unscrews the removable member 2, which has the effect of causing the tubing A1 to slide in a sealed manner in the piston lip 16.
- the contact between the inlet T2 of the teat T and the extension tube 18 is broken, so that the closed volume Vc then communicates with the secondary reservoir Tr and the extension tube 18.
- the sealed sliding generates a depression which will suck fluid product into the applicator whose volume is growing.
- the fluid product comes from the main reservoir R or from the secondary reservoir Tr, ie from both reservoirs at the same time, in proportions which are dependent on the pressure drops of the flows. In any case, the filling of the A2 applicator is thus ensured, with a few more doses in reserve in the T teat.
- the user can then apply the fluid product as he wishes by putting the free end of the tubing A1 in contact with the target (skin, nail, hair, etc.). During the application, he presses gently and continuously on the teat T to drive fluid product from the secondary reservoir Tr into the applicator A2.
- the user puts the movable member 2 back in place on the base part 1 by first engaging the tubing A1 around the extension tube 18 and screwing the threaded ring A5 in the threaded sleeve 13. As soon as the tubing A1 comes into leaktight sliding contact with the piston lip 16, the air and fluid product contained in the cup 15, the extension tube 18 and the dip tube 17 are pushed back into the main reservoir R. The end of screwing corresponds to the engagement of the extension tube in the inlet T2 of the teat T. We then returned to the starting position of figure 2. We can note that it does not it is not necessary to completely screw the moving member 2 back in to refill the teat T. Indeed, as soon as the tubing A1 comes into tight contact with the piston lip 16, the teat T can be crushed and its elastic return will suck up product fluid coming from the main reservoir R into the teat T.
- Figure 3 shows a second embodiment of the invention, in which the base part 1' differs from the first embodiment in that the cup 15, the dip tube 17 and the extension tube 18' are in one piece.
- the extension tube 18 ' occupies more than 90%, even 95%, of the volume Va of the applicator A2', which is formed by a tube A1 ', which occupies more than 90%, even 95%, of the volume Vg of the cup 15.
- the free end of the pipe A1' comes into contact or almost with the bottom of the cup 15.
- the extension tube 18' is separated from the teat T' by a duct A42, which is formed by an insert A41 of the applicator element A'.
- This insert A41 extends into the teat T′, so as to reduce its dead volume.
- the conduit A42 defines an input A43 which communicates directly with the applicator A2' and an output A44 which communicates directly with the pacifier T'. It should be noted that the conduit A42 extends in the extension and the alignment of the extension tube 18 ', but there is no contact between the extension tube 18' and the insert A41: they are separated from a distance of the order of a few tenths of a millimetre, or even one or two millimeters. Thus, even in the rest position, the nipple T and the extension tube 18' communicate with the residual volume defined on either side of the tubing A1'.
- Vu is greater than the cumulative volumes of the dip tube 17, the extension tube 18' and the duct A42. Seen can be more than 5 times greater than these cumulative volumes.
- the removable member 2' defines an axial height Ho and the tubing A1' or the applicator A2' defines an axial height Ha: Ha ⁇ Ho/2.
- the teat T' defines an axial height Ht: Ht > Ha.
- the embodiment of Figure 4 differs from the previous ones first in that there is no extension tube.
- the A1” applicator is empty and fills cup 15 to more than 90%. It directly connects the dip tube 17 to the teat T”, which comprises a bellows T4′ and an internal stud T 7 to reduce the dead volume of the teat T”, so that the useful actuation volume Vu is close to the volume maximum at rest.
- Vu is larger than the combined volumes of dip tube 17 and applicator A1”. Seen can be more than 5 times greater than these cumulative volumes.
- the removable member 2' defines an axial height Ho and the tubing A1” or the applicator A2” defines an axial height Ha: Ha ⁇ Ho/2.
- the teat T defines an axial height Ht: Ht > Ha, which makes it possible to have a short applicator with increased precision of application.
- piston lip 16 could possibly be eliminated in this variant.
- the teat performs a secondary reservoir function to supply the applicator during the application operation.
- the cumulative volumes of the elements upstream of the teat are less than the useful suction volume of the teat.
- the sealed sliding of the tubing in the piston lip makes it possible to fill the applicator, once the teat is filled.
- the implementation of the extension tube allows optimal filling of the teat by reducing, or even neutralizing, the dead or closed volumes of the cup.
- the pacifier could be crushed by an intermediate element, on which the user will act: the pressure would therefore no longer be exerted directly by the user on the pacifier.
- a fluid product application dispenser is available, the removable member of which can contain several doses to supply the applicator.
