Abstract
Description
Title of the invention: Dropper dispenser
[0001] The present invention relates to a dropper-type dispenser for dispensing a fluid product in the form of drops. The drops are dispensed one after the other. The drop(s) fall from the dispenser by gravity onto a desired application surface. The preferred fields of application of the present invention are those of perfumery, cosmetics or pharmacy.
[0002] It is known to dispense pharmaceutical and cosmetic products drop by drop using a dropper dispenser consisting of a pipette and a suction / discharge system generally made up of a simple elastomer teat.
[0003] More sophisticated suction / discharge systems also exist. They perform suction by simply pressing a button or by unscrewing the dropper from the bottle.
[0004] Such devices are known in particular from documents EP 2854596 A1, KR 101462162 B1 and KR 200453126 Yl.
[0005] The invention proposes a dropper dispenser providing simplified gestures, the dispenser always being ready for use and requiring minimal use of the user's hands.
[0006] The invention thus relates to a dropper dispenser comprising: a) a bottle with a longitudinal axis, forming a reservoir of product to be dispensed, b) a base serving as a support for the bottle, (c) a locking system for locking the bottle to the base, the bottle being, when locked to the base, axially movable between an upper end position and a lower end position, (d) a product dispensing area, configured to allow the formation of product drops, and (e) a pump system, configured so that an axial movement of the bottle from the lower position to the upper position causes air to move downwards in the bottle, the air thus moved carrying with it the product present in the bottle to a product storage area (which is in particular distinct from the product dispensing area), and so that an axial movement of the bottle from the upper end position to the lower end position causes the product to circulate from the product storage area to the dispensing area.
[0007] In a first embodiment, the pump system is integrated into the bottle.
[0008] In this case, the locking system may comprise at least one protrusion of the bottle cooperating by clipping with at least one associated groove of the base, each groove having for the protuberance associated with it a lower stop and an upper stop between which the protuberance is able to move axially, the position of said at least one protuberance in abutment against the lower stop defining the lower end position of the bottle and the position of said at least one protuberance in abutment against the upper stop defining the upper end position of the bottle.
[0009] The bottle may comprise two protrusions and the base may comprise two associated grooves.
[0010] The base may comprise several sets of two grooves, the grooves of each set having a height different from the height of the grooves of the other set(s).
[0011] The pump system may comprise: - a pump body, secured to an end zone of the bottle and coaxial with said end zone, - a cover covering the pump body and fitted with an axial orifice, - a product dispensing tube, comprising at its lower end the product dispensing zone which is advantageously in axial abutment against the base, an upper part of the product dispensing tube being housed in the pump body via a lower axial opening of the pump body, the pump body thus being movable in axial translation relative to the dispensing tube during an axial movement of the bottle, the dispensing tube being provided at its upper end with a housing receiving a non-return valve comprising a ball resting on a spring, the spring being supported at its lower end on said housing and being supported at its upper end on a zone of the cover located around the orifice of the cover, so that the ball obstructs the orifice of the cover when the bottle is in its lower end position,and that the ball is at a distance from the orifice of the cover when the bottle is in its upper end position, the distribution tube further comprising in its upper part at least one radial orifice, , - a piston disposed radially between the product dispensing tube and the pump body, the piston comprising an inner annular portion and an outer annular portion which is tightly mounted on the pump body so that a movement of the pump body causes a movement of the piston, the inner annular portion being movable in axial translation between a lower stop and an upper stop of the product dispensing tube, the position of the piston when the inner annular portion is in abutment against the lower stop of the product dispensing tube defining a lower end position of the piston and the position of the piston when the inner annular portion is in abutment against the upper stop of the product dispensing tube defining an upper end position of the piston, the piston thus being in its upper end position when the bottle is in its upper end position and the piston being in its lower end position when the bottle is in its lower end position, the inner annular portion of the piston obstructing said at least one radial orifice of the dispensing tube when the piston is in its upper end position and not obstructing said at least one radial orifice of the dispensing tube when the piston is in its lower end position.
[0012] The bottle may comprise a movable bottom as well as a bottle bottom provided with at least one orifice.
[0013] Alternatively, the bottle may comprise a flexible pouch receiving the product to be dispensed.
[0014] In a second embodiment, the pump system is integrated into the base.
[0015] In this case, the base may comprise a base body and a movable ring axially relative to the base body between a lower end position of the ring and an upper end position of the ring, a spring secured to the base body allowing axial movement of the ring between its lower end position and its upper end position, the ring being provided with an external thread, and the bottle may comprise a bottle body comprising at least one air inlet orifice communicating with a non-return valve allowing air to enter the bottle and preventing air from exiting the bottle, the bottle body being covered by a screw head, the screw head being provided with a first threaded zone for screwing the screw head onto the bottle body and a second threaded zone for screwing the screw head onto the external thread of the ring,the base further comprising a product dispensing tube which is in communication at its upper end with the screwed head of the bottle in the operational configuration of the device, the product dispensing tube being formed in the lower end position of the ring by an axial conduit of the base body and in the upper end position of the ring by the axial conduit of the body extended by an axial conduit of the ring, the product dispensing tube comprising at its upper end a non-return valve allowing the entry of the product into the dispensing tube and preventing the passage of the product from the dispensing tube to the bottle, the dispensing tube comprising at its lower end a non-return valve forming the product dispensing zone and which allows the exit of the product from the dispensing tube and which prevents the entry of the product into the dispensing tube.
[0016] The screwed head may be provided with a cover, for example a frangible cover, such as for example a seal, and the ring may comprise a cutting element capable of cutting at least part of the frangible lid when screwing the bottle onto the ring.
[0017] The check valves can be umbrella valves.
[0018] In a third embodiment, the pump system is independent of the base and the bottle.

[0088] As illustrated in [Fig.l], a dropper dispenser 1 according to the invention comprises a base 2 serving as a support for a bottle 3 containing a fluid cosmetic product. The dispenser 1 allows the dispensing of drops at a flow zone 4.
[0089] The base 2 is equipped with a bottle locking system 3. It is designed to ensure the stability and balance of the assembly.
[0090] The bottle 3 containing the cosmetic product incorporates a pump system. The pump system allows air to pass into the bottle so that the bottle 3 does not deform during use.
[0091] The base 2 has an opening allowing the passage of the cosmetic product which can then be recovered at the level of the open cell.
[0092] The operation of distributor 1 is as follows.
[0093] When first used, the user 5 removes the cover protecting the bottle / bottle pump. He then locks the bottle 3 onto the base 2 and can place the assembly thus secured on a work surface or on the edge of a sink. The dispenser 1 is then ready for use ([Fig.2]).
[0094] It is then sufficient to press on the bottle 3 to release the dose of product and collect it at the flow zone 4 with the finger or an applicator ([Fig.3] ). The product can then be applied to the user ([Fig.4]).
[0095] The user 5 will be able to adjust the dose by using part or all of the stroke of the dispenser 1, either manually or via a dose indexing system described below.
[0096] Once the bottle 3 is empty, it is sufficient to unlock it and replace it on the base 2 with a new bottle 3. It is possible to use bottles 3 of different formulas on the same base 2, one after the other, without risk of contamination of the formulas.
[0097] The dispenser 1 may comprise a membrane, for example made of silicone, placed at the outlet orifice of the cosmetic product, which makes it possible to limit the contact of air with the cosmetic product and therefore to prevent it from drying out. This also makes it possible to limit the phenomenon of hanging drops and to ensure the cleanliness of the base 2.
[0098] If the user 5 decides to remove the bottle 3 from its base 2 while the latter is not completely empty, he can keep it using a stopper blocking the outlet orifice.
[0099] It is thus possible to produce a bottle holder 6 integrated into the base, providing the formulas necessary for the user's daily or weekly use, or more simply allowing refills to be available ([Fig.5]).
[0100] Figures 6 to 55 illustrate a dropper dispenser 1 according to the invention, in accordance with a first embodiment. In this first embodiment, a pump system 10 is integrated into the bottle 3.
[0101] In a version without a pocket, the dispenser 1 comprises the base 2 (figures 16 to 18) and a bottle 3 comprising a movable bottom 7 as well as a bottle bottom 8 provided with at least one orifice 9 (figures 10 to 15).
[0102] The bottle 3 is provided with protrusions 3a ([Fig. 12]) intended to cooperate by clipping with associated grooves 2a of the base 2 ([Fig. 16]).
[0103] In this first embodiment, the pump system 10 comprises a pump body 11, a cover 12 covering the pump body 10 and which is provided with an axial orifice 13, a product distribution tube 14 which may comprise a lower part 14a (an outlet tube) and an upper part 14b (a perforated tube) provided with radial orifices 15, a piston 16, a spring 17, a ball 18 and a seal 19 (figures 19 to 41).
[0104] The pump body 11 comprises a rib 11a ([Fig.22]) which allows the pump body 11 to be clipped into a groove 3b of the bottle 3 ([Fig. 12]).
[0105] The piston 16 comprises an inner annular portion 16b and an outer annular portion 16a. The inner annular portion 16b and the outer annular portion 16a are connected, at an intermediate height of the piston 16, by a transverse ring 16c ( [Fig.36]). So as to be able to be mounted tightly on the pump body 11, the portion outer annular portion 16a may comprise an upper portion and a lower portion intended to be in contact with the pump body 11, the upper portion and the inner portion being connected by an intermediate portion of diameter smaller than the diameter of the upper portion and the lower portion, the intermediate portion thus being intended not to be in contact with the pump body 11 when the piston 16 is inserted into the pump body 11.
[0106] [Fig.42] illustrates a rest position of the dropper dispenser 1.
[0107] In this position, the bottle 3 is filled with fluid product, the pump system 10 is in the rest position (the conical spring 17 is not compressed but it is still under stress), the reservoir is therefore in the high position.
[0108] The volume located between the transverse ring 16c of the piston 16 and the orifice 13 of the cover 12 will be called the chamber V ([Fig.43]). The volume V is likely to vary during use of the product.
[0109] User 5 then applies pressure to the top of the bottle ([Fig.43]). The movement is represented by arrow F ([Fig.44]).
[0110] The bottle 3, the pump body 11 and the pump body cover 12 translate downwards until they come into abutment against the base 2 (each protuberance 3a of the bottle moves between a lower stop 2a 1 and an upper stop 2a2 which axially delimit the groove 2a). The pump body cover 12 compresses the conical spring 17 and the ball 18 obstructs the orifice 13 of the cover 12. The ball 18 - conical spring 17 assembly has a non-return valve function.
[0111] The piston 16 compresses the volume of air in the chamber V. The air is expelled from the chamber V (represented by the arrows F') and moves towards the outlet tube 14a via the orifices 15 in the perforated tube 14b ([Fig.44]).
[0112] User 5 then releases the pressure exerted on bottle 3 ([Fig.45]).
[0113] During this phase, the user 5 stops pressing on the bottle 3, which is then pushed upwards thanks to the spring 17.
[0114] When there is no longer any pressure exerted on the bottle 3, the spring 17 will push the cover 12 upwards, thus releasing the inlet orifice for the cosmetic product. Indeed, under the effect of gravity, the ball 18 will be attracted downwards and will bear against the conical spring 17.
[0115] When the bottle 3 is raised, the pump body 11 drives the piston 16 upwards. In fact, the piston 16 is adjusted slightly tightly on the pump body 11 (the piston 16 is thus integral with the pump body 11). When the piston 16 comes to translate until it is in abutment against the perforated tube 14b, the latter will obstruct the orifices 15 of the perforated tube 14b.
[0116] In a second step, the bottle 3 will continue to rise until it reaches the upper stop ([Fig.46]). During this phase, a depression is created by increasing the volume of chamber V. The cosmetic product is therefore sucked into chamber V of the mechanism (as shown by arrows F').
[0117] The configuration illustrated in [Fig.47] is identical to the second configuration, except that this time cosmetic product is expelled from chamber V and not air. The second configuration only concerns the first use of the dispenser 1.
[0118] Once again, user 5 applies pressure to the bottle of the dropper dispenser 1.
[0119] The bottle 3, the pump body 11 and the pump body cover 12 translate downwards until they come into abutment against the base 2. The pump body cover 12 compresses the conical spring 17 and the ball 18 obstructs the orifice 13 of the cover 12.
[0120] This time, the pump body 11 drives the piston 16 downwards in order to free the outlet orifices 15 of the perforated tube 14b.
[0121] The piston 16 compresses the volume of cosmetic product located in the chamber V. The cosmetic product is expelled from the chamber V and moves towards the outlet tube 14a via the orifices 15 of the perforated tube 14b.
[0122] Thus, in this first embodiment:
[0123] - The product distribution tube 14 comprises at its lower end the zone product distribution tube 4 which is in axial abutment against the base 2, the perforated tube 14b being housed in the pump body 11 via a lower axial opening 11b of the pump body 11.
[0124] - The pump body 11 is thus movable in axial translation relative to the tube of distribution 14 during an axial movement of the bottle 3, the perforated distribution tube 14b being provided at its upper end with a housing 14b 1 ([Fig.33]) receiving the non-return valve comprising the ball 18 resting on the spring 17. The spring 17 bears at its lower end on the housing 14bl and bears at its upper end on a zone of the cover located around the orifice 13 of the cover 12, the ball 18 obstructing the orifice 13 of the cover 12 when the bottle 3 is in its lower end position, and the ball 18 being at a distance from the orifice 13 of the cover 12 when the bottle 3 is in its upper end position, the perforated tube 14b further comprising at least one radial orifice 15.
[0125] - The piston 16 is arranged radially between the product distribution tube 14 and the pump body 11, the piston 16 comprising an internal annular portion 16b and an external annular portion 16a tightly mounted on the pump body 11 so that a movement of the pump body 11 causes a movement of the piston 16, the internal annular portion being movable in axial translation between a lower stop and an upper stop of the product distribution tube 14, the position of the piston 16 when the inner annular portion 16b is in abutment against the lower stop of the product dispensing tube 14 defining a lower end position of the piston 16 and the position of the piston 16 when the inner annular portion 16b is in abutment against the upper stop of the product dispensing tube 14 defining an upper end position of the piston 16, the piston 16 thus being in its upper end position when the bottle 3 is in its upper end position and the piston 16 being in its lower end position when the bottle 3 is in its lower end position, the inner annular portion 16b of the piston 16 obstructing the orifices 15 of the dispensing tube 14 when the piston 16 is in its upper end position and not obstructing the orifices 15 of the dispensing tube 14 when the piston 16 is in its lower end position.
[0126] In this first embodiment, the bottle 3 may or may not include a pocket forming a reservoir of fluid product to be dispensed.
[0127] In the configuration without a pocket, illustrated in figures 48 to 51, the bottle 3 can comprise a movable bottom 7. When the bottle 3 is pressed and the fluid product is withdrawn, the movable bottom 7 will move downwards.
[0128] In order to balance the pressure between the movable bottom 7 and the bottom of the bottle 3, the two orifices 9 of the bottom of the bottle 8 allow air to pass into the bottle 3. The passage of air allows the pressures to be balanced and allows the movable bottom 7 to descend. Thus, there will be no depression inside the bottle 3 and therefore no deformation of the latter.
[0129] The movable bottom 7 ensures a certain seal so that the product cannot escape from the bottle 3 when the assembly is turned over.
[0130] As the bottle 3 is used, the movable bottom 7 moves from top to bottom (Figures 48 to 51). The movable bottom 7 makes it possible to obtain an excellent restitution rate since the movable bottom 7 rubs the walls of the bottle 3 and brings all the product back to the inlet of the pump system 10.
[0131] In the configuration with a pocket, illustrated in [Fig.52], a pocket 20 is inserted into the bottle 3. There is no need for a movable bottom because the pocket 20 deforms during use of the product. Over time, the pocket 20 will deform and will thus offer a good rate of restitution of the product.
[0132] In order to be able to adjust the quantity of product to be dispensed, an indexing mechanism can be used.
[0133] When changing a bottle, the user clips the bottle 3, which has two lugs 3a, into a groove 2a located inside the base 2.
[0134] In a second step, the user turns the bottle 3 so as to align the mark located on the bottle (shown schematically by an arrow 21) opposite a dispensed quantity indicator located on the base. The indicator is shown schematically by a drop 22 plus or smaller depending on the quantity of product delivered associated ([Fig.53]).
[0135] When the bottle 3 is clipped onto the base 2, the two lugs 3a of the bottle 3 are housed in the groove 2a of the base 2.
[0136] Opposite each drop 22 there are grooves 2a making it possible to limit more or less the travel of the two lugs 3a and therefore of the bottle 3.
[0137] The longer the stroke, the greater the volume sucked and compressed. And the longer this stroke, the greater the quantity of product delivered.
[0138] For example, in the configuration illustrated in [Fig.54] (position PI), the adjustment makes it possible to deliver the largest quantity of product.
[0139] To change this setting, simply turn the bottle 3 until you reach the desired position.
[0140] [Fig.55] is a top sectional view of the base 2, in order to better visualize the different positions. There are two grooves per position because there are two lugs 3a, which offers a total of three different positions: P1, P2 and P3. There is an angle of 60° between each groove (groove).
[0141] Figures 56 to 65 illustrate a dropper dispenser 1 according to the invention, in accordance with a second embodiment. In this second embodiment, the pump system 10 is integrated into the base 2. This ecological solution allows the user to keep and reuse the base 2 integrating the pump system 10, and the bottle 3 containing only the cosmetic product P can thus be recycled once emptied.
[0142] Once filled, the bottle 3 is closed by means of a screwed head 23, in particular a screwed head which cannot be unscrewed subsequently, for example using anti-unscrewing notches. If the head is not screwed, it can be ultrasonically welded to the bottle after filling.
[0143] The head 23 has an integrated cover 24.
[0144] The user first screws the bottle 3 onto a thread of a ring 25 (collar) located inside the base 2. During screwing, a knife 26 present inside the ring 25 will partially cut the cover 24. A washer 31 can be arranged under the cover 24 and resting on the ring 25 (figures 61 and 62). The washer 31, fixed / welded to the collar 25, makes it possible to hold the collar valve in place.
[0145] The base 2 thus comprises a base body and the ring 25 which is axially movable relative to the base body between a lower end position and an upper end position. A spring 17 allows axial movement of the ring 25 between its lower end position and its upper end position, the ring 25 being provided with an external thread.
[0146] The bottle 3 comprises a bottle body comprising at least one air inlet orifice 27 communicating with a non-return valve 28 allowing air to enter the bottle 3 and preventing air from escaping, the bottle 3 being covered by the screwed head 23 provided with the cover 24 ([Fig.57]).
[0147] The screwed head 23 is provided with a first threaded zone for screwing the screwed head onto the bottle 3 and a second threaded zone for screwing the threaded head onto the external thread of the ring 25.
[0148] The base 2 further comprises a product dispensing tube 14 comprising at its upper end a zone of the base which is a zone for receiving the seal 24, said receiving zone being provided with a non-return valve 29 allowing the entry of the product P into the dispensing tube 14 and preventing the passage of the product P from the dispensing tube 14 to the bottle 3, the dispensing tube 14 comprising at its lower end a non-return valve 29 forming the product dispensing zone 4 delimited by a nozzle 30 and which allows the exit of the product P from the dispensing tube 14 and which prevents the entry of the product P into the dispensing tube 14 ([Fig.59]).
[0149] When the bottle 3 is screwed onto the base 2, the user presses on the bottle 3. During the first use, air will come out at the outlet orifice ([Fig.63]). When the bottle 3 rises under the action of a spring 17, cosmetic product P enters the chamber V, and air enters through the vents 27 and the umbrella valve 28 ([Fig.64]). Thus, the bottle 3 is not deformed.
[0150] The user presses the bottle 3 again, which allows a dose of cosmetic product P to be dispensed ([Fig.65]).
[0151] Once the bottle 3 is in place, the user must empty it completely before being able to put in a new one, otherwise if the bottle is removed during use, the remaining cosmetic product will leak.
[0152] In this second embodiment, low-viscous cosmetic products are preferred. If the product is very viscous and the user, after removing the bottle, leaves the base empty for a while, the cosmetic product remaining in the pump in the open air could dry out and clog the pump. Therefore, if the product is too viscous, it will be preferable to implement the dispenser according to the first embodiment, with a pump system integrated into the bottle, so that it is changed with each new refill.
[0153] Alternatively, it is possible to envisage that the base does not have a bottom.
[0154] Finally, as described above for the first embodiment, the base can be equipped with a system for adjusting the dose of product delivered, making it possible to limit the travel of the bottle more or less. Thus, the user can choose the travel associated with a dose of product dispensed according to his needs. The greater the travel of the bottle, the greater the quantity of product delivered.
[0155] In a third embodiment, illustrated in Figures 66 to 68, the system of Pump 10 is independent of base 2 and bottle 3. This means you can clean the pump every time you refill it, have different pumps with different dosages that can be adapted to the product used, and only have to buy the pump again if it stops working.
[0156] A conventional dropper dispenser requires holding the bottle in one hand and a pipette in the other hand to collect the cosmetic product. The product must then be dispensed with the pipette in the hand or directly onto the face, but once the dose of product has been dispensed, you need to know what to do with the pipette.
[0157] With the dispenser according to the invention, it is possible to simplify the gestures because one hand is used to operate the bottle to deliver the dose of product and the other hand is used to collect the dose of product. Then, both hands are free to apply the product to the face. This reduces the risks of falling, breakage and loss of product.
[0158] In addition, the device is always ready for use and has the advantage of maximizing the restitution rate of the cosmetic product by inverting the bottle. This is often not the case for a conventional dropper dispenser whose pipette does not go to the bottom of the bottle or if the bottom of the bottle is curved the pipette cannot recover the product which is on the periphery.
[0159] The dispenser according to the first embodiment makes it possible to deliver more viscous cosmetic products and also to protect the product from the risks of contamination and oxidation due to its “airless” operation.
[0160] The dispenser according to the invention can therefore advantageously replace conventional dropper dispensers.
