    [0001] The invention relates to a process for extracting a liquid such as perfume present in a liquid dispensing apparatus. Conventionally, a liquid dispensing apparatus comprises a liquid container, and connected to the container, a liquid dispensing device which is adapted to draw liquid into the container (generally by pumping liquid) and to convey it through a path to at least one liquid outlet for dispensing this liquid to the outside of the apparatus. Conventional apparatuses are satisfactory in terms of liquid dispensing functionality, especially perfume. However, the liquid dispensing devices in these devices are generally configured to dispense a predetermined dose of liquid. They do not allow to increase this dose. On the other hand, refilling in liquid of another liquid container with such an apparatus is generally not possible. The liquid dispensing device mounted on the container is indeed not always removable. In view of the foregoing, it would therefore be advantageous to be able to extract liquid from such a liquid dispensing apparatus in an unconventional manner, in particular so as to be able to increase the dose of extracted liquid (with respect to a predetermined dose by the configuration of the liquid). device) and / or reload another container with liquid. The subject of the present invention is thus a method for extracting liquid from a liquid dispensing apparatus, the apparatus comprising a liquid container, and connected to the container, a liquid dispensing device which is capable of taking out liquid in the container and to route it by a path to at least one liquid outlet for dispensing this liquid to the outside, characterized in that the method comprises a step of injection under pressure of a volume of extraction gas in the container so as to exert pressure on the container liquid to circulate it in at least a portion of the device and allow the extraction of a predetermined amount of liquid from the apparatus. The injection of a volume of gas into the container has the effect of expelling a predetermined quantity of the liquid (corresponding substantially to the volume of gas injected at the compression height of the gas near) of the container in at least a portion of the device liquid distribution (said at least a portion of the device is in communication, on the one hand, with the liquid of said container and on the other hand, with the outside), and then out of the device. The injected gas thus expels the liquid from the container and forces its extraction. Note that in order to effect gas injection and liquid extraction, generally, a portion of the conventional liquid dispensing device is removed (eg, pusher or actuating member, the other portion including the pumping means When in conventional operation, the liquid dispensing device 15 is generally actuated from the outside (for example by a downward prop which causes a pumping of the liquid) to take a predetermined and limited dose ( by construction of the device) of liquid which will then be distributed externally According to other possible characteristics taken separately or in combination with each other: - the apparatus comprising at least one compensation air inlet inside the container to compensate, by a volume of outside air, the volume of liquid dispensed by the liquid dispensing device, the volume e of exhaust gas is injected through said at least one compensation air inlet, whereby the compensation air inlet (s) is used to inject the volume of exhaust gas; the liquid dispensing device comprises means for pumping the liquid contained in the receptacle and dispensing the liquid thus pumped outside the apparatus, said pumping means being able to occupy, on the one hand, a rest position and, on the other hand, under the action of an actuation command exerted from outside the apparatus, at least one pumping position in which liquid is likely to be pumped from the the interior of the container and conveyed by the liquid path to said at least one liquid outlet of the liquid dispensing device; the liquid container is provided with an opening in which the liquid dispensing device is mounted, said at least one compensation air inlet being located at said opening of the container and being adapted, on the one hand, , to be open to the outside to allow a compensating external air inlet into the container when the pumping means occupy said at least one pumping position and liquid is conveyed by the liquid supply path to said at least one liquid outlet of the liquid dispensing device and, on the other hand, to be closed when the pumping means occupy the rest position; before the injection of a volume of extraction gas, the method comprises a step of actuating the pumping means so that they occupy a pumping position in which the at least one compensation air inlet 15 is open to the outside; it will be noted that in this pumping position at least a portion of the liquid flow path is open to the outside; however, depending on the design of the apparatus, in a variant, said at least a portion of the liquid flow path is closed and opens to the outside only under the pressure of the liquid; the liquid dispensing device comprises an actuating part comprising said at least one liquid outlet of the dispensing device and which is removably mounted on the pumping means, the method comprising a preliminary disassembly and withdrawal step; said actuating member; - The method comprises a step of mounting on the pumping means of a liquid extraction system out of the apparatus by air injection; the system for extracting liquid from the apparatus by gas injection comprises means for injecting extraction gas and means for extracting the liquid.
    [0002] The invention also relates to a liquid extraction system of a gas injection liquid dispensing apparatus, characterized in that it comprises: extraction gas injection means which are intended for injecting into the apparatus a volume of extraction gas; means for extracting from the apparatus a predetermined quantity of liquid. This system is attached to the liquid dispensing apparatus which has for example removed the actuating part (dispensing pusher) and is mounted on the pumping means. This system can be configured according to the intended application and contains in itself all the gas injection means and liquid extraction. It plays in a way the role of an interface between the device (or part of it) and the outside. According to a possible characteristic, the means for extracting from the apparatus the predetermined quantity of liquid comprise a liquid channel, a first end of which is intended to communicate with the apparatus and a second end of which The opposite outlet end is in communication with the outside, the second opposite outlet end optionally comprising: an outlet port, one or more spray ports, a spout. Other features and advantages will become apparent from the following description, given solely by way of nonlimiting example and with reference to the accompanying drawings, in which: - Figures 1 to 3 illustrate a liquid dispensing apparatus according to one embodiment of the invention in three different positions; FIG. 4 is a schematic view of a first embodiment of a gas injection liquid extraction system associated with a portion of the apparatus of FIGS. 1 to 3; Figure 5 is a schematic view of a second embodiment of a gas injection liquid extraction system associated with a portion of the apparatus of Figures 1 to 3; FIG. 6 is a schematic view of a third embodiment of a gas injection liquid extraction system associated with a portion of the apparatus of FIGS. 1 to 3. As represented in FIGS. and designated by the general reference numeral 10, a liquid dispensing apparatus such as perfume according to one embodiment of the invention comprises, shown in the position of normal use of the apparatus: - a rigid container 12 containing a liquid (eg perfume) to be dispensed outside said container, for example by spraying the liquid, - a liquid dispensing device 14 which is mounted on the vertically disposed container 12. More particularly, the container 12 has, at its upper end 12a opposite the bottom 12b, an opening 16 in which is engaged a portion of the device 14. The opening 16 is arranged at a narrowed section forming a neck of the container. However, the opening could alternatively be made in a container whose upper end has a different shape (different neck or no neck). The rigid container is for example a glass bottle. The device 14 is for example fixed to the container by crimping by means of a capsule 18 (eg aluminum) which surrounds a part of the device and is supported, on the one hand, on said device and, on the other hand, on a rim formed at the neck 12c of the container. The capsule 18 is shaped to match the outer shape of the parts it surrounds. According to an alternative embodiment not shown, the device is mounted and fixed to the container by screwing at the opening of the latter, generally via a thread on the inner surface of the wall defining the opening ( here, the relevant wall defines the neck of the container). The device 14 comprises means 20 for pumping (pump) the liquid which is present in the container and for dispensing the liquid pumped outside said device. The device 14 also comprises a so-called dispensing part which is situated outside the receptacle (above the receptacle in the normal use position of the apparatus) and which comprises a part or actuating member 22 (pusher). distribution) to actuate the pumping of the liquid and its distribution. This member is represented here by a dispensing pusher which takes the form of a cap or hollow cover which caps the pumping means 20. The user exerts with a finger a downward vertical pressure on the pusher 22 as shown in FIG. 2 to pump liquid for distribution. The pumping means 20 comprise: - a body or jacket 24, - a piston 26 which is able to slide along the inner face of the jacket while ensuring a tight contact between the two parts during this movement, and - a return spring 27 installed in a compressed manner between the piston located above and an internal shoulder 24a of the lower part of the liner. The piston 26 comprises a body whose central portion comprises a pierced wall in order to place in communication, on command, the areas located on either side of the wall. The liner comprises a part called the chamber inside which the piston moves and which houses the return spring 27. The chamber is delimited at the bottom by the internal bearing shoulder of the spring. The pumping means also comprise a hollow rod 28 which is fixed at its base 28a to the piston 26 and at its opposite end 28b to the pusher 22. More particularly, the opposite end 28b of the rod is fitted into an internal extra thickness of the pusher. in which is arranged a channel 29 for the outlet of liquid. This channel is in communication with the conduit internal to the hollow rod 28. The external action of downward vertical thrust on the pusher 22 is transmitted to the rod 28 which presses on the piston and thus makes it possible to slide it towards the lower part of the piston. the sleeve 24 by compressing the spring 27 (Figure 2). The pumping means also comprise two valve systems 30, 32 (seat and valve): one 30 is placed between the piston and the rod and the other 32 is placed in the lower part of the jacket. Each valve system comprises a valve seat and a movable valve relative to its seat and which takes for example the form of a ball. The valve system 30 comprises, on the one hand, a seat 30a provided with a through opening 30b which corresponds to the pierced wall of the central part of the piston 26 and, on the other hand, a ball 30c which closes or not according to its position (FIG. 1 or 2), the opening 30b. The inner duct to the hollow rod 28 has an enlarged portion 28c in which the ball 30c can move when it deviates from the opening and frees access. The inner conduit is extended by a portion 28d of reduced diameter smaller than that of the ball to limit its movement. The jacket 24 is extended vertically downwardly beyond the internal spring-bearing shoulder 24a by a first narrowed portion 24b which, in turn, is connected by a second convergent portion 24c to a third portion 24d. forming chimney. A suction tube 34 or plunger tube 15 is fitted into the chimney 24d and extends towards the bottom 12b of the container. The valve system 32 comprises, on the one hand, a seat 32a which is formed by the second convergent portion 24c and, on the other hand, a ball 32b which closes or not, depending on its position (FIG. 1, 2 or 3) , the entrance to the chimney 20 24d. As shown in Figure 1, the capsule 18 comprises a lower portion 18a which is shaped around an outer rim of the neck 12c of the container. The capsule 18 also includes an upper portion 18b which encloses the arrangement of the liner 24, the piston 26 and the rod 28 arranged concentrically. The upper portion 18b forms a cap whose first portion extends substantially axially away from the lower portion 18a and a second portion extends radially towards the rod 28 but leaving a radial gap between said upper portion 18b and said stem 28. This radial space forms an external air compensation inlet 30 inside the container as illustrated in FIG. 2. In this zone, enclosed by the upper portion 18b, the jacket has at its upper end an external rim 24e. against which rests laterally the first portion of the upper portion 18b and on which rests a piece 36 (eg washer) forming axial stop for both the piston 26 and the rod 28. The rod 28 has indeed a part external with an enlarged outer diameter which abuts against the piece 36 and therefore remains confined inside the piston and the jacket. Note that the piece 36 has an inner diameter greater than the outer diameter of the rod 28 in its non-enlarged outer portion (this portion surrounds the reduced diameter conduit portion 28d) in order to leave a radial space between the two elements in the position of Figure 2.
    [0003] The second portion of radial extension of the upper portion 18b bears on the piece 36. The sleeve 24 also comprises one or more through holes 38 in its substantially cylindrical wall which defines the chamber inside which the piston 26 slides. .
    [0004] This or these holes 38 (only one is shown in the figures) are formed in an area of the wall at the level (altitude) of which is disposed the piston 26 when the apparatus is in the rest position of FIG. , the hole 38 communicates the internal space to the container and the space between the body of the piston 26 and the cylindrical wall of the jacket (this second space does not communicate with the remaining part of the jacket because of the sealing of the contact between the piston body, via the upper and lower sealing lips, and the wall of the jacket). The normal operation of the apparatus 10 will now be described with reference to FIGS. 1 to 3.
    [0005] In general, the translational movement of the piston in the jacket (induced by an external actuation on the part of the user) associated with the reciprocating actuation of the two valve systems generates a pumping phenomenon of the liquid contained in the container. The piston is actuated by the hollow rod in which will pass the liquid to be pumped and which is itself actuated by a finger of the user on a dispensing pusher. In Figure 1, in the rest position, the piston 26 is pushed up the sleeve 24 (abutting against the piece 36) by the spring 27. The upper valve system 30 is closed and the valve system 32 from the bottom. The pumping means are in the high position. The dip tube is immersed in the liquid contained in the container. After priming the pumping means, a volume of liquid is stored waiting in the jacket 24, between the piston 26 and the ball 32b. This volume of liquid corresponds to the dose of product which will be distributed by the pumping means during the following pumping operation illustrated in FIG. 2. As illustrated in FIG. 2, when the user actuates the pusher 22 (according to FIG. vertical arrow), the piston 26 slides in the jacket 24, the upper valve system 30 opens (the ball 30c deviates from its seat 30a), the valve system 32 of the bottom remains closed, the spring 27 is compresses and the axial space between the piston and the ball 32b is reduced. The liquid contained in this space passes through the valve system 30 open while the closed valve system 32 prevents any discharge of the liquid inside the container.
    [0006] Note that in the design of the apparatus of Figures 1 to 3 the valve system 30 opens mechanically via a system of stops when the pumping means are in the low position. According to one variant, the valve system 30 opens before the pumping means reach the bottom position in abutment.
    [0007] The liquid rises in the conduit portions 28c, 28d of the rod 28, passes into the channel 29 and exits through the outlet end 29a to be distributed outside the apparatus. The liquid thus borrows a routing path, said normal, to exit the dispensing device and therefore the device. This path comprises the plunger tube 34, the open valve system 30, the jacket 24, the valve system 32 open, the conduit portions 28c and 28d of the rod 28 and the channel 29. The dose expelled by the pumping phenomenon generates a vacuum in the sealed and non-deformable container which is compensated by a return of compensating air into the container to rebalance the internal pressure of the container. At rest (Figure 1) the device is perfectly sealed vis-à-vis the outside. However, when actuating the pumping means this seal is broken punctually to allow an external volume of air to enter the container to rebalance the internal pressure of the container. The apparatus 10 is thus structured to allow the entry of compensating air (air intake) and, therefore, the communication between the outside and the inside of the container, during pumping. As already described above, to do this, one or more air inlets are arranged in the component parts of the device. The peripheral internal space 40 arranged between the upper capsule portion 18b and the rod 28 constitutes such a compensation air inlet. This air inlet 40 is brought into communication with the hole 38 of the liner when the piston is lowered (FIG. 2) and thus with the interior of the container, thus creating a passage for the supply of outside air into the chamber. container as illustrated by the arrows indicating the air path. In Figure 3, the user has released its thrust on the pusher 22 from a low position (in abutment) pumping means. The return spring 27 pushes the piston 26 upwards, the valve system 30 closes and the valve system 32 opens (the ball 32b deviates from its seat 32a). The space between the piston and the valve system is enlarged, which creates a vacuum and thus a suction of liquid through the dip tube 34 immersed (as indicated by the arrows). The liquid rises into the tube and begins to fill the internal space of the jacket via the open valve system 32 to arrive at the position of FIG. 1. The air intake passages described above are closed again as and as the piston rises, especially when the hole 38 is masked / closed by the body of the piston 26 which arrives at its level. The tightness of the device is thus restored. FIG. 4 illustrates a first embodiment of a system for extracting liquid from the apparatus 10 by injecting gas such as air associated with a part of the apparatus 10 of FIGS. to extract liquid from this device. Firstly, the dispensing pusher 22 (actuating part) of the apparatus of FIG. 1 is removed and then the apparatus is capped (devoid of the pusher 22), that is, say the free end 28b of the rod 28 and the upper portion 18b of the capsule 18, an injection head and extraction 50. The injection head and extraction 50 forms an example of a system extracting liquid from the apparatus 10 by air injection. The head 50 comprises an axial housing 52 whose diameter corresponds to the outer diameter of the free end 28b to accommodate a portion of said free end. The head 50 also comprises an axial duct 54 (liquid conveying channel forming liquid extraction means external to the apparatus) extending the axial housing 52, of internal diameter corresponding to the internal diameter of the duct portion 28d, and opening on the outside through an outlet opening 54a. The conduit 54 communicates with the rod 28 of the device by its opposite end 54b. A peripheral seal 56 is arranged in the axial housing 52 around the free end 28b and a projecting portion of the rod. Similarly, a peripheral seal 58 is provided in the wall of the head which comes into contact with the upper portion 18b of the capsule. The filling head 50 also comprises an air injection channel 60 (air injection means) which is formed in at least a part of the thickness or height of the head. This channel comprises an inlet orifice 60a disposed at one of the walls of the head and an outlet orifice 60b arranged at the opposite end of the channel and which opens into an area of the head surrounding the rod 28. More particularly , the orifice 60b opens into an annular space 62 located at the inlet of the axial housing 52. The channel 60 is here oriented with an inclination angle of less than 90 ° with respect to the axis of the axial duct 54. The head 50 is mounted on the device. The head 50 is then pressed in order to actuate the pumping means in the low position and to lock the head in this position on the apparatus by locking means (eg snap-fastening) so as to obtain a sealed contact with the apparatus. The extraction of liquid by gas injection is ready to be carried out. According to a variant, the head is locked to the apparatus for an intermediate position of the pumping means. The valve system 30 is then partially open or closed and it will open completely under the pressure of liquid. As explained above, in the pumping position one or more passages for the return of air are arranged in the apparatus through the communication of the peripheral space 40 and the hole or holes 38. In the extraction position of Figure 4, this or these passages are open and air is introduced or injected under pressure (through appropriate means such as a piston or other) via the injection channel 60 (from a source of air not shown) in the space 62, then in the passage or passages through the space 40 and the hole or holes 38, to open into the container. The support on the means of pumping makes them inoperative. Injection pressure varies in a range from 200 mbar to 2 bar. Following this introduction of an external air volume (exhaust air), the volume of air contained in the container increases and, as a result, exerts pressure on the liquid present in the container. Under the effect of this thrust on the liquid, the latter rises in the dispensing device through the tube 34. The valve system 32 opens under the pressure of the liquid (the ball 32b deviates from its seat 32a and rises ). The valve system 30 is open (the ball 30c deviates from its seat 30a and rises) by design because of the support on the pumping means. Pushed by the injected air, the liquid is thus forced to circulate in a part of the normal path for conveying the liquid (tube 34, open valve 30, jacket 24, valve 32 open, rod 28) through the liquid distribution device then in the axial conduit 54 before being expelled out of the apparatus through the orifice 54a. The portion of the liquid pathway that is located in the portion of the liquid dispensing device remaining in the apparatus after removal of the dispensing pusher forms liquid extraction means of the apparatus. The fluid channel 54 forms, meanwhile, liquid extraction means 25 which are present in the system 50 attached to the device after withdrawal of the dispensing pusher. Since the pumping means are rendered inoperative when they are depressed, the quantity of liquid which is extracted from the apparatus no longer depends on these means (displacement of the pump) but on the volume of air injected into the container. FIG. 5 illustrates a second embodiment of an air injection liquid extraction system associated with a portion of the apparatus 10 of FIGS. 1 to 3 for extracting liquid from this apparatus.
    [0008] Firstly, the dispensing pusher 22 (actuating part) of the apparatus of FIG. 1 is removed and then the apparatus is capped (without the pusher 22), that is to say the free end 28b of the rod 28 and the upper portion 18b of the capsule 18, an injection head and extraction 70. The injection head and extraction 70 forms an example of a system of extraction of liquid from the apparatus 10 by air injection. The head 70 comprises the axial housing 52 of the head 50 of FIG. 4. The head 70 also comprises an internal liquid conveying channel 72 (the channel 72 forms means for extracting the liquid external to the apparatus) which extends the axial housing 52, of inner diameter corresponding to the inner diameter of the conduit portion 28d, and opens out through a spray opening orifice 72a forming a spray nozzle. The channel 72 forms a bend and comprises a first axial portion 74, in the axis of the axial housing 52 and a second portion 76 which extends perpendicular to the first portion and away from it, towards the orifice 72a. The head 70 has a lateral protuberance 70a in which extends a fraction of the second portion 76 of the channel and the orifice 72a in order to lengthen the channel in its part upstream of the orifice. Note however that this growth can be omitted in a variant. The opening opening is then arranged directly in the lateral vertical wall of the block forming the head 70. The operation of the system 70 mounted on the apparatus 10 (devoid of the dispensing pusher) is identical to that of the system 50 mounted on the apparatus as shown in FIG. 4: the air injected into the container 12 through the compensation air inlet (s) propels liquid into the liquid dispensing device (without the pusher 22) and into the channel 76 in order to expel through the orifice 72a in the form of a spray jet. The same advantages as mentioned for the embodiment of FIG. 4 apply here. The difference between the two modes is the extraction head, the form in which the liquid exits from it, and the use of the extracted liquid. Note that the head 70 is similar to a push button such as the button 22 except that it incorporates gas injection means (eg air). In the embodiments described, the extraction head is static: it is connected to the pumping means in the low position and does not move during the gas injection. According to a variant not shown, the extraction head is not locked on the pumping means 20 as with the pusher 22. It can then be used for dispensing the liquid as a dispensing pusher. Then, when desired, a mechanical blocking of the head on the pumping means supported in the low position intervenes to perform the gas injection. The head is thus able to extract liquid from the container 10 according to two modes of operation. According to a variant not shown, the elbow at the junction between the first 74 and second 76 parts may be rounded to improve the flow of liquid in the channel. FIG. 6 illustrates a third embodiment of an air injection liquid extraction system 15 associated with a portion of the apparatus 10 of FIGS. 1 to 3 for extracting liquid from this apparatus. Firstly, the dispensing pusher 22 (actuating part) of the apparatus of FIG. 1 is removed and then the apparatus is capped (without the pusher 22), that is to say the free end 28b of the rod 28 and the upper portion 18b of the capsule 18, an injection and extraction head 80. The injection and extraction head 80 forms an example of a system extracting liquid from the apparatus 10 by air injection. The head 80 includes the axial housing 52 of the head 70 of Figure 5. The head 80 also includes an internal liquid channel 82 (the channel 82 forms liquid extraction means external to the apparatus) which extends the axial housing 52, of internal diameter corresponding to the internal diameter of the conduit portion 28d, and opens outwardly through a through orifice 82a. The channel 82 comprises two parts 84, 86 connected to each other at a right angle as the channel 72 of FIG. 5. The head 80 also comprises, relative to the main body, a lateral protrusion 80a in which a fraction of the second portion 86 of the channel and the orifice 82a to form a spout (valve). The second portion 86 thus extends along a first fraction 86a perpendicular to the first portion 84 and away from it, and then according to a second fraction 86b within the lateral protrusion 80a. This second fraction 86b is first rectilinear, then is bent down to the orifice 82a. The operation of the system 80 mounted on the apparatus 10 (devoid of the dispensing pusher) is substantially identical to that of the system 70 mounted on the apparatus as shown in FIG. 5: the air injected into the container 12 by the one or more Compensation air inlets propel liquid into the liquid dispensing device (without the pusher 22) and into the channel 86 to expel it through the orifice 82a of the spout in the form of drops of liquid. As shown in FIG. 6, another open container or bottle 90 is disposed below the pouring spout 80a to collect drops of liquid extracted from the container 12. This allows the container 90 to be filled. The container 90 illustrated in FIG. 6 has an external thread 92 which allows the attachment to the opening 94 of a pump or plug not shown. In the field of perfumery this arrangement makes it possible to produce samples in containers such as the container 90 which are of smaller capacity than the container 12. To do this, the pumping means 20 of the liquid distribution device are crimped on the container 12, do not need to be disassembled by the liquid extraction method according to the invention which has just been described. The same advantages as mentioned for the embodiment of FIG. 5 apply here. The difference between the two modes is the extraction head, the form in which the liquid comes out of it, and the use of the extracted liquid. Note that another gas than air can be used. For example, an oxygen-free gas to limit the oxidation of the container liquid may be used. Nitrogen or other inert gas or other gases such as freon or other similar gases for their compressibility may be used.
    [0009] According to another variant not shown, the gas injection head and liquid extraction may adopt other forms. According to still other variants not shown, the shape, number and arrangement of the inlet or the compensating air inlets in the vessel may vary. The shape, number and arrangement of the passage (s) for the compensation air inside the apparatus may also vary. The gas injection channel 60 may be arranged differently. Several gas injection channels can also be envisaged.
    [0010] Furthermore, the apparatus can take different forms and the internal parts as well as the air intake system. The liquid dispensing device may for example be screwed or otherwise secured to the container. The container can adopt different shapes and a neck of different shapes, or even no collar.
