Definitions
- the present invention relates to a device comprising a base piece and a removable member removably mounted on the base piece.
- the removable member slides axially sealingly in the base piece on a determined axial stroke.
- the preferred fields of application of the present invention are those of perfumery, cosmetics or even pharmacy.
- the base piece can be integral with a fluid reservoir, and the movable member can support an applicator.
- WO2013 / 017803 discloses an applicator dispenser comprising a removable member provided with an applicator which is adapted to be removed axially by sliding out of a base piece which comprises a bucket of which the bottom is pierced with an injection port connected to a dip tube. More specifically, the removable member is unscrewed from the base piece, which causes its sliding axial displacement: at the end of unscrewing, the removable member can be completely removed and separated from the base piece to be able to put the applicator in contact with a suitable surface, such as the skin. During unscrewing, a depression is formed between the base piece and the removable member, so that the fluid stored in a reservoir is sucked through the dip tube and the injection port to fill the applicator.
- the applicator is formed by a tubing defining internally a sampling and application space.
- the tubing is surrounded by a piston which slides inside a sliding shaft formed by the upper part of the bucket.
- the suction which makes it possible to fill the applicator by injection is created by the sliding of the piston inside the upper part of the bucket.
- Another problem with the dispenser of this document WO2013 / 017803 lies in the fact that the cup is partially filled with fluid once the applicator is removed. This is clearly visible in Figure 6 of this document.
- the present invention aims to overcome the aforementioned drawbacks of the prior art by defining an applicator dispenser of the type described in WO2013 / 017803, but whose bucket contents are purged in another way, in order to leave the tube diver filled, or at least partly, fluid product.
- the present invention proposes a device for sampling and application of fluid product comprising:
- a base part mounted on a reservoir of fluid comprising a dip tube and a bucket in which is formed an injection orifice connected to the dip tube, the bucket being provided with a piston, and
- the bucket is provided with a drain valve which selectively communicates the interior of the bucket with the fluid reservoir, so as to discharge the fluid contained in the bucket to the tank, when replacing the removable body on the base piece.
- the fluid contained in the cup is pressurized and can return directly to the tank through the drain valve.
- the drain valve comprises at least one through hole through the wall thickness of the bucket, said at least one through hole being bordered by a valve seat, the drain valve also comprising a movable valve member arranged to outside the bucket and able to close the passage hole, when a depression is created in the bucket.
- the drain valve opens to a pressure threshold in the bucket which is lower than that required to discharge the contents of the bucket through the dip tube .
- a fine dip tube (outside diameter less than 1 mm) can be used to increase the pressure drop.
- the movable valve member does not need to rest in a sealed manner on its seat in the idle state, so that it is already open even before the overpressure is formed inside the bucket.
- the mobile valve member is immediately pressed onto its seat and hermetically closes the hole (s) of passage.
- the bucket comprises a bottom, advantageously flat and perpendicular to the axis of sliding, at which the drain valve is located.
- the through holes may extend axially and perpendicularly across the flat bottom.
- the bottom can be crossed by a conduit which connects the dip tube to the injection port.
- This conduit may be formed by the bucket or by the dip tube.
- the injection port is formed at the free upper end of the conduit.
- the drain valve comprises a plurality of passage holes arranged around the duct.
- the base part comprises a tube holder in which is engaged an end of the plunger tube, the movable valve member being fixedly mounted around this tube holder, which advantageously forms a fastening profile.
- the movable valve member is then fixedly mounted around the upper part of the plunger tube.
- the movable valve member comprises a fixing heel in fixed engagement with the tube holder and a flexible corolla which extends on said at least one through hole for closing selectively.
- the injection orifice is located inside the sampling and application space, when the removable member is in place on the base part.
- the injection port is located outside the sampling and application space, when the removable member is in place on the base piece.
- the spirit of the invention lies in the fact of draining the contents of the bucket in the tank, when replacing the removable member, by passing it through a unidirectional valve, preferably disposed at the bottom of the bucket .
- FIG. 1 is a vertical cross-sectional view through a dispenser according to a first embodiment of the invention
- FIG. 2 is a greatly enlarged view of detail A of FIG. 1;
- FIG. 3 is a view similar to FIG. 2 for a second embodiment of the invention;
- FIG. 4 is a view similar to FIGS. 2 and 3 for a third embodiment of the invention, and Figures 5 and 6 are perspective views showing two versions of through holes in the bottom of the bucket.
- FIG. 1 To describe in detail the structure and operation of a fluid dispenser applicator which can be used as a base dispenser to incorporate a drain valve according to the present invention.
- the three embodiments of the invention which will be described below will only detail the differences with respect to this basic applicator dispenser.
- the dispenser firstly comprises a fluid reservoir 1 which is only partially represented. Indeed, Figure 1 shows only the upper part of the tank 1 which forms a neck 1 1 which is quite conventional, with an external reinforcement for hanging.
- the fluid reservoir 1 may be of any kind and be made of any material, since the reservoir is not a critical element for the present invention.
- the dispenser comprises two other component parts, namely a base part 2 which is fixedly mounted on the tank 1 and a removable member 3 which is removably mounted on the base part 2.
- the base part 2 comprises hooking means, which may be in the form of a skirt 20, slit or not, which engages around the neck 1 1 of the tank 1. This is a quite conventional design for the fixation of a dispensing member in the fields of cosmetics, perfumery or pharmacy.
- the attachment of the skirt 20 around the neck 1 1 can be used to crush an annular collar 4 on the upper edge of the neck 1 1.
- the base part 2 also comprises a bucket 21 which extends inside the neck 1 1 of the tank. At its lower end, the bucket 21 forms a bottom 22 which is traversed by a conduit 23 which is formed at the junction between a tube holder 25 and a cannula 26.
- the tube holder 25 serves as a support for a dip tube 24 which extends inside the tank 1 to near its bottom.
- the dip tube 24 comprises an upper end forcibly engaged in the tube holder 25.
- the cannula 26 extends inside the cup 21 and forms at its upper free end an injection port 261.
- Bucket 21 is provided with a piston 27 which forms a piston lip.
- the piston 27 is an insert which is placed in the bucket 21 and held for example by snapping. It is also possible to provide the piston 27 by overmolding or bi-injection. The technique of holding the piston 27 in the bucket 21 is not critical for the present invention.
- the base piece 2 forms a sleeve forming an internal thread 28.
- the base piece 2 may comprise an outer trim band 29, which may possibly participate in maintaining the skirt 20 around the neck 1 1.
- the removable member 3 comprises a gripping appendage 31 that the user can grasp between his fingers. Internally, the removable member 3 forms an external thread 32 adapted to cooperate with the internal thread 28 of the base piece 2.
- the removable member 3 also comprises a tubular 33 of substantially cylindrical shape and internally defining a sampling space and application 35 in which is positioned the cannula 26 and the injection port 261, as can be seen in Figure 1. It can be seen that this space 35 is open at its lower end and closed at its upper end, so as to define a blind space. The opening of the space 35 is located near the bottom 22 of the bucket 21. It can also be seen that the tubing 33 comes into sealed contact with the lip of the piston 27.
- a user can grasp the gripping appendage 31 to impart to it a rotational movement, which has the effect of unscrewing the removable member 3 from the base part 2.
- the tubing 33 slides sealingly inside the piston 27, creating a vacuum inside the sampling and application space 35.
- This depression will generate a fluid suction from the reservoir 1 to through the dip tube 24 and the injection port 261.
- the fluid product will thus be injected inside the sampling and application space 35.
- the injection of fluid product will continue until the space 35 is filled and even beyond, both than the tubing 33 is in sealing sliding contact inside the piston 27. It is thus possible to define an axial sliding race between the piston 27 and the tubing 33.
- FIG. 2 it can be seen that the bottom 22 is pierced with at least two through holes 221 which pass through the wall thickness of the bottom.
- These passage holes 221 have an axial orientation parallel to that of the sliding of the removable member 3.
- the outer wall of the bottom 22 around the through holes 221 forms a valve seat 222.
- a movable valve member 5 is disposed around the tube holder 25 so as to extend against the valve seat 222, thus closing the through holes 221.
- This movable valve member 5 is here in the form of a flat annular seal which is fixedly held at its inner annular edge; while the remainder of the flat gasket is movable away from the seat 222 by elastic deformation. More specifically, the inner annular edge forms a fixed anchor heel 51 which is held around the tube holder 25 between the bottom
- This drain valve is formed outside the bucket 21 and inside the tank 1. It opens preferably to a pressure threshold in the bucket which is lower than that required to discharge the contents of the bucket through the dip tube.
- the bucket can be emptied of its contents through the drain valve leaving the dip tube filled with fluid.
- the removable member 3 can be replaced on the base piece 2 without emptying the dip tube 24, so that at the next removal of the removable member 3, the fluid is immediately
- the movable valve member 5 does not even need to rest sealingly on its seat 222 in the idle state, so that it is already open even before the overpressure is formed inside the bucket 21.
- the movable valve member 5 is immediately pressed onto its seat 222 and hermetically closes the through holes 221.
- a non-return valve upstream or downstream of the dip tube to prevent any fluid passage from the bucket 21 to the reservoir 1.
- Such a valve could be housed at the level of the conduit 23 or the cannula 26.
- FIG. 3 there is shown a second embodiment for a drain valve according to the invention.
- the bottom 22 of the bucket 21 can be identical to or similar to that of the first embodiment of Figure 2.
- the difference lies in the anchoring mode of the movable valve member 5 ', which has an anchor heel 51' which is rounded and comes s snap into an anchor groove 252 of the tube holder 25 of corresponding shape.
- the upper edge of the groove 252 may extend in the extension of the valve seat 222.
- FIG. 4 we see a third embodiment for a drain valve according to the invention.
- the bottom 22 of the bucket 21 may be identical or similar to that of the first embodiment of FIG. 2. It may however be noted that there is no cannula 26, so that the injection orifice 261 is located outside the sampling and application space 35. It can be said that the injection orifice 261 is just outside the space 35. It is also possible to arrange the orifice 261 just inside the space 35.
- This configuration is more suitable for fluid products with low viscosity, such as perfume, while the configuration of Figures 2 and 3, with a canula that extends far into the interior of space 35, is more suitable for more viscous fluid products, such as creams or serums.
- FIG. 4 is also different from the previous ones by its movable valve member 5 "which comprises an anchoring heel 51" in the form of a sheath which encloses the tube holder 25 on a certain height.
- the advantage of this design lies in the fact that the tube holder can be conventional, without rib or anchor groove.
- the movable valve member 5, 5 ', 5 " it comprises a fixed anchor heel 51, 51', 51" integral with the tube holder 25 and a flexible corolla 52 which allows selectively closing the through holes 221 as a function of the pressure inside the bucket 21.
- the movable valve member 5; 5 '; 5 can be mounted mechanically on the tube holder 25, but it can also be made by bi-injection with chemically incompatible materials, allowing a mechanical strength, but no chemical bond, so as to ensure the detachment of the flexible corolla 52.
- the dip tube 24 remains partially, and preferably entirely, filled with fluid, so that the filling of the sampling and application space 35 begins at the beginning of the tight sliding of the organ. 3
- the formation of the through holes 222 is easy because they have an axial orientation which is that of molding / demoulding.
- the addition of a seal as a movable valve member is an easy operation.
- the arrangement of the drain valve at the bottom 22 of the bucket 21 is preferred, but not exclusive.
