Description

The present invention relates to the field of transferring a liquid present in a first container to an empty bottle. In particular, the present invention relates to a device for refilling a liquid product, such as perfume.

The present invention also relates to the use of such a charging device to allow the filling of a bottle, by another bottle, said refill.

A number of products are marketed in bottles that have a luxurious character. These bottles have for example many aesthetic reasons quite difficult to manufacture and can also be made of noble materials, thus increasing their cost. The luxurious nature of a bottle makes it possible to highlight the container which also has a high cost and allows to perfect the image of the product. This is particularly the case for perfume bottles. Thus, the use of a refill bottle, of less value than the product it contains, allows to fill and reuse a luxurious bottle which, by its quality, is generally perceived as a non-disposable object.

It may also be helpful to transfer a product from a lightly worked bottle (refill) to a more luxurious or presentable bottle to address an environmental concern, for example, if the refill is recyclable or to meet an economic concern.

The perfume bottles typically consist of a container having a threaded neck on which is screwed a spray head. Similarly, the refill bottles generally comprise a container having a threaded neck on which is screwed a screw cap.

To refill or fill an empty perfume bottle, a simple way is to unscrew the spray head and manually transfer the contents of the refill, after unscrewing the cap.

However, this way has disadvantages. Indeed, given the fact that the neck of said refillable dispenser is typically small size, it takes some skill or manual skill to perform the transfer or transfer of perfume from a refill bottle to the perfume bottle. The usual consequences of a transfer, except to be very skilful, are on the one hand a loss of product contained in the refill, often a perfume of great price, and on the other hand, a risk of soiling clothes or hands , with the risk of having a stubborn and lasting smell associated with such an operation, the product or the perfume having been able to spread and impregnate a fabric.

In the state of the art, in addition to the manual transfer, funnel-shaped devices are also known. The funnel is a cone-shaped, tube-ended instrument which serves to pour not only a liquid but also a powder, granule or paste, for example into a smaller aperture container. The funnel is usually made of glass, plastic or metal.

The documents GB 2 396 318 , JP 2007/182255 or JP2004 / 4306982 describe improved funnels. For example, the first document describes a funnel device comprising a flotation means for blocking the cone of the funnel, in order to avoid overflowing the product during the transfer.

However, with such funnel devices, the user can be splashed by drops of the product to be reloaded during the transfer, which has the consequence of causing product losses and dirt for the user.

The document FR 2 867 761 discloses a device for refilling a container having a threaded neck comprising: a) a first container for containing a product to be transferred into the second container, b) a cooperating means for forming a connection of said first and second containers c) means for sealing the second container; d) means for transferring the product contained in the first container to the second container. This device allows the transfer of a full bottle (refill) to an empty bottle to fill, the same capacity as the refill. Thus, if there is still liquid in the bottle to be filled, the refill can not be emptied completely in the bottle. Therefore, when uncoupling the refill with the bottle, the liquid still present in the refill will overflow, which will cause losses.

The present invention aims to provide a new charging device that avoids all or part of the aforementioned drawbacks.

• une recharge contenant le liquide, et
• un système de transvasement, apte à faire passer sélectivement le liquide depuis la recharge vers le flacon,
  ledit système de transvasement comprenant:
  1. a) une première pièce fixée à la recharge, et comprenant un premier conduit de liquide et un premier conduit d'air, en communication avec la recharge,
  2. b) une deuxième pièce connectée à la première pièce, et destinée à être fixée au flacon, ladite deuxième pièce comprenant un deuxième conduit de liquide et un deuxième conduit d'air destinés à être en communication avec le flacon,

la première et la deuxième pièces étant solidaires en translation et libres en rotation entre une configuration dite ouverte, dans laquelle lesdits premiers et deuxièmes conduits, respectivement de liquide et d'air, sont alignés, assurant ainsi le passage du liquide et de l'air entre la recharge et le flacon, et une configuration dite fermée, dans laquelle lesdits premiers et deuxièmes conduits, respectivement de liquide et d'air, ne sont pas alignés, interdisant ainsi le passage du liquide et de l'air entre la recharge et le flacon.For this purpose, the subject of the invention is a liquid refilling device for a bottle, characterized in that it comprises:

• a refill containing the liquid, and
• a transfer system, capable of selectively passing the liquid from the refill to the vial,
  said transfer system comprising:
  1. a) a first part fixed to the refill, and comprising a first liquid duct and a first air duct, in communication with the refill,
  2. b) a second piece connected to the first piece, and intended to be fixed to the bottle, said second piece comprising a second liquid duct and a second air duct intended to be in communication with the bottle,

the first and second parts being integral in translation and free in rotation between a so-called open configuration, in which said first and second conduits, respectively of liquid and air, are aligned, thereby ensuring the passage of liquid and air between the refill and the bottle, and a so-called closed configuration, in which said first and second conduits, respectively liquid and air, are not aligned, thus preventing the passage of liquid and air between the refill and the bottle.

By the characteristics of the device according to the invention, it has the advantage of being an alternative to the funnel, while allowing not to pour liquid next to. The liquid is also never in contact with the user. In addition, the charging device is anti-overflow. Indeed the flow stops automatically when the level of the bottle to be filled is reached, that is to say when the air duct is clogged by the liquid level.

Preferably, said second ducts have the same length and the length of the first liquid duct is less than the length of the first duct of air, thus simultaneously ensuring the passage of the liquid from the refill to the flask and the passage of the air from the bottle to the refill in open configuration of the refill device. The fact that said second conduits have the same length, allows in the open configuration of the device that when the liquid level in the bottle has reached the lower end of these conduits, the flow of air and liquid is simply stopped. Thus, depending on the shape of the bottle to be filled, the length of said second conduits will be greater or smaller. For example, if the bottle to be filled is long and thin, the second conduits will have a length large enough to open into the bottle at the level where the user wants the liquid stops. If the bottle to be filled is wide and flat, the second conduits will have a shorter length, so as to allow proper filling of the bottle.

Advantageously, the second part comprises at least one thread allowing screwing and unscrewing of the refill device on the bottle.

Preferably, the first piece comprises at least one godron capable, in the closed configuration of said device, to cooperate with at least one folding lug present on the second piece, so that, during screwing, the first piece rotates said second room.

Advantageously, a locking means is disposed in an area of the second part, intended to be in contact with the upper end of the bottle, so as to stop the rotation of the second part relative to the bottle when the upper end of the bottle reaches the blocking means.

Preferably, the first part comprises at least one screw abutment adapted to cooperate with at least one first abutment present on the second part, so as to block the rotation of the first part when the screw abutment comes into contact with said first part. stop, the first and second conduits, respectively, of air and liquid being arranged to be aligned when the screw stop comes into contact with with the first stop of the second piece, the screw stop being disposed at a different level from the at least one godron.

In particular, the first part comprises at least one unscrewing stop adapted to cooperate with at least one second abutment present on the second part, so that, during unscrewing and once the unscrewing stop is in contact with the second stop, the rotation of the first part causes the rotation of the second part.

Preferably, the second piece is integral in translation with the first piece by latching means.

Advantageously, the second part comprises a reception space comprising the net and a closure means extending at least inside said reception space, said closure means being able to fit into the interior of the room. a neck of the vial and comprising said second conduits, so as to allow, in open configuration, the passage of liquid and air in the vial.

In particular, the first part comprises a first reception zone having a thread in which is screwed a threaded neck present on the refill.

Preferably, the first part comprises an anti-unscrewing means preventing disassembly of the refill and said first part.

Preferably, the first part comprises a second receiving zone, adjacent to said first receiving zone along the longitudinal axis of said first part, characterized in that said first liquid conduit extends into the second receiving zone, and said first air duct extends into both the first and second receiving areas.

Advantageously, in said second receiving zone, said first air and liquid ducts are surrounded by an air collector adapted, in a closed configuration, to be in communication with said second ducts of air and liquid.

As indicated above and with reference to the Figures 1 and 2 the present invention relates to a liquid refilling device 100 of a bottle, such as a perfume bottle 3. This refilling device 100 firstly comprises a first container, called refill 2 and a transfer system 1 which is adapted to be screwed onto a threaded neck 3a of the perfume bottle 3.

The refill 2 is commonly a bottle or a cylindrical tube of glass or plastic filled with a liquid, such as perfume. The refill 2 has a threaded neck 2a. In addition, it generally has a sufficiently large capacity so that it can fill several empty perfume bottles 3.

On the neck 2a of the refill is disposed the transfer system 1. It consists mainly of two parts: a first part called outer part 5, substantially cylindrical and a second part, said inner part 4, also substantially cylindrical and partially inserted in the outer part 5 coaxially, the two parts 4 and 5 being integral in translation. The neck 2a of the refill 2 is attached to the transfer system 1 via the outer part 5. As will be described below, the transfer system 1 also comprises at least one seal 30, 40, preferably two.

The external part 5 which is illustrated in particular on Figures 1, 3 and 16 comprises two reception zones: a first reception zone 18 ( figure 1 ) which serves to receive the threaded neck 2a of the refill 2 (referred to as the receiving zone of the refill) and a second reception zone 17 ( figure 1 ) which serves to receive the inner part 4 (called receiving zone of the inner part). These two receiving zones 17, 18 are adjacent and follow one another in the longitudinal axis (X axis) of the outer part 5. They are separated by a transverse plate 5a which has two orifices 5b, 5c in order to form or be crossed by, respectively, a liquid conduit 11 and an air duct 12 within the outer part 5.

The receiving zone 18 of the substantially cylindrical shaped refill itself has two parts, a first part extending in a first direction along the X axis from the transverse plate 5a and a second part, which extends in the same sense as the first and from it. This second part has a wider section to receive the shoulder of the refill 2 while the first part has a thread 8 which serves to screw the neck 2a of the refill 2 to the outer part 5. Between the transverse plate 5a and the collar neck 2a is preferably arranged a seal 40. In addition, figure, at the inner wall of the end of the outer part 5 connected to the refill 2, an anti-unscrewing means 35 preventing disassembly of the refill 2 of the transfer system 1 once it is mounted. The fact that the device 100 is unmountable makes it possible to have a traceability on the product (perfume) contained in the refill 2.

The receiving zone 17 of the inner part, also of substantially cylindrical shape, also has two parts: a first part 33 which extends from the transverse plate 5a along the X axis in a second direction, opposite to the first direction mentioned above and a second part 34, which extends from the first part 33 and in the same direction as this one. The first part 33 comprises in the wall of the outer part 5, latching means (groove 14) to the inner part 4. The second part 34 comprises at its end farthest from the plate 5a, first two gadroons 20a, 20b diametrically opposed, then two abutments 22, also diametrically opposed, and each comprising a screwing abutment 22a and an unscrewing abutment 22b ( figure 16 ). These flutes 20a, 20b and stops 22 are arranged in the internal face of the cylindrical wall of the outer part 5, but not at the same level, the abutments 22 are here slightly above gadroons. The flutes 20a, 20b also have the function of cooperating respectively with lugs 19a, 19b arranged on the inner part 4, and the two stops 22 of the outer part 5 have the function of cooperating with also a first and a second stops 21a and 21b present on the inner part 4, so that the outer part 5 can rotate the inner part 4. The second part 34 has a section slightly greater than that of the first part 33.

In addition, the outer part 5 comprises two ducts, a liquid duct 11 and an air duct 12. The liquid duct 11 extends, from the opening 5b of the transverse plate 5a, into the receiving zone. 17 of the inner part 4, and in particular until the end of the first part 33 of this zone 17. The air duct extends from the orifice 5a, on either side of the plate 5a. both in the receiving zone 18 of the refill and in the receiving zone 17 of the inner part and in particular in the first part of the receiving zone 18 and in the first part 33 of the receiving zone 17 Thus, the air duct 12 is longer than the duct 11 for passing a liquid. These two ducts 11 and 12 are arranged so that their first ends open into the neck 2a of the refill 2 and their second ends open to the right of a closure means 7, also having two ducts 9 , 10, and which is arranged on the inner part 4.

The outer part 5 also comprises a cylindrical wall 16, arranged around the ducts 11, 12 and extending from the plate crosswise 5a, partially in the first portion 33 of the second receiving zone 17 of the inner part. This wall 16 is adapted to cooperate with another cylindrical wall 15 disposed in the inner part 4 to form an air collector 26 for the transfer system 1.

As shown in figure 17 the inner part 4 also comprises two parts: a first part 32 comprising latching means, namely a rib 13 adapted to snap into the groove 14 of the outer part 5, and a second part including a space of reception 31 of the neck 3a perfume bottle 3. These two portions 32, 31 are adjacent and follow in the longitudinal axis (X axis) of the inner part 4. They are separated by a transverse plate 4a which, as for the plate 5a, has two orifices 4b, 4c so as to form respectively: a liquid duct 10 and an air duct 9 within the inner part 4.

The first portion 32 extends from the transverse plate 4a in the first portion 33 of the receiving zone 17de the inner part. The outer wall of the inner part 4 is embedded in the inner wall of the part 33 of the part 5 and is fixed via the ratchet rib 13 / groove 14. As seen above, the inner part 4 comprises a cylindrical wall 15. This wall 15 extends from the plate 4a in the portion 32 so as to surround the cylindrical wall 16 of the outer part 5. An air collector 26 is thus formed. As visible on the figure 12 when the ducts 9 and 10 of the inner part 4 are not in front of the ducts 11 and 12 of the outer part 5, they open into the air collector 26.

The second part 31 comprises in its internal wall a net 6 adapted to cooperate with the neck 3a and allowing the vial 3 to be screwed onto the refilling device 100. Between the neck of the neck 3a and the plate 4a is disposed a seal 30 (in form of washer) to ensure a seal between the bottle and the transfer system 1. As shown in FIG. figure 17 the inner part 4 comprises the two foldable lugs 19a and 19b, diametrically opposite and arranged on the outer wall of the inner part and in particular at the end of the second part 31 farthest from the first part 32. Au same level are also the two stops 21a and 21b diametrically opposing adapted to cooperate with the screwing abutments 22a and unscrewing 22b of the outer part 5. In addition, as mentioned above, the inner part 4 comprises a closure means 7. This sealing means extends to from the tray 4a to the receiving zone of the bottle (towards the second portion 31), so as to be embedded and plug the neck 3a. This shut-off means comprises two ducts: a liquid duct 10 and an air duct 9. These two ducts 9, 10 have the same length and are capable, depending on the rotation of the outer part 5 with respect to the internal part 4, to be aligned with respectively the air duct 12 and the liquid duct 11 of the outer part 5. When the ducts of the outer and inner part are aligned, it is said that the charging device 100 is in configuration open, while when these conduits are not aligned, it is said that the charging device 100 is in closed configuration. The operation of said recharging device 100 will now be described with reference to Figures 1 to 19 .

On the figure 1 , the refill carries the first outer part 5. The second inner part 4 is housed in the first outer part 5 in closed configuration.

The first operation to be performed by the user ( figure 3 ) is to screw on the bottle 3 the charging device 100: the closure means 7 is introduced into the neck 3 of the bottle, and the charging device 100 is screwed.

During this action, the outer part 5 in particular rotates the inner part 4. In fact, with reference to the Figures 4 to 6 , the gadroons 20a, 20b of the outer part rotate the inner part 4 by contact with, respectively, the folding lugs 19a and 19b of said inner part 4. In this step, the inner parts 4 and outer 5 are in configuration closed (see Figures 3 to 6 ). Thus, no liquid flows (the liquid and air ducts of the internal and external parts are not aligned).

At the end of the screwing of the refilling device 100 to the perfume bottle 3, the elastomer seal 30 comes into contact with the neck of the bottle 3 ( figure 4 ). However, this seal 30 prevents the inner part 4 from rotating relative to the bottle 3 and being driven by the outer part 5. The rotation of the inner part 4 is indeed blocked. As illustrated on the Figures 7 and 9 when collar neck 3a has reached the seal 30, the rotation of the inner part 4 is blocked, the folding pins 19a and 19b of this piece disappear under the godrons 20a and 20b ( figure 8a to 8c ) of the outer part 5.

The user continues to rotate the outer piece 5 around the inner piece until the first stop 22a of the outer piece abuts against a first stop 21a of the inner piece (rotation on 1/4 turn). fig.9a and 9b ) thus aligning the liquid conduits 10 and 11 and air 9 and 12 of the two parts, the device 100 is now in open configuration ( figure 7 ).

The liquid can thus flow from the refill 2 to the perfume bottle to be filled 3 ( figure 10 ) by simple gravity. The air repelled by the filling of the bottle is transferred into the refill 2 to compensate for the depression generated by the flow of the liquid from the refill 2 to the vial 3. The difference in length between the total air duct f12 and the duct liquid 11 causes the air to rise through line 12 and the liquid to flow through line 11.

When, as illustrated on the figure 11 , the liquid level 25 is reached and the air duct 9 is blocked, the air 24 can not, therefore, circulate more, and pass from one container to another. The flow therefore stops automatically, because the volume of liquid can no longer be compensated by a volume of air, the whole is in depression, the liquid no longer flows. At the end of this step, the bottle 3 is filled with perfume. Adjusting the length of the ducts 9 and 10 also makes it possible to adjust the level of filling of the bottle according to its shape.

Once the bottle 3 is filled ( Figures 12 to 14 ), the user unscrews the refill device 100 of the vial 3. For this, at first, the adhesion of the seal 30 to the neck of the neck 3a of the vial 3 prevents the rotation of the inner part 4, and c ' is therefore the outer part 5 which pivots around the inner part 4 for a quarter turn in the unscrewing direction. This movement a quarter turn, will misalign the air ducts 9 and 12 and liquid 10 and 11. The device 100 is found in closed configuration. Then, in a second step, the second abutment stop 22b of the part external 5 abuts against a second stop 21 b of the inner part 4 and drives the inner part 4 in rotation, the inner part 4 is no longer blocked by the seal 30. It returns to the starting position shown in FIG. figure 15 .

During the unscrewing, the transfer system 1 moves away from the liquid level 25, thus opening the air duct 9. Thus, in the closed position, the two ducts 9 and 10 located in the internal part 4 and the air present, communicate by the air manifold 26. The liquid stagnant in the liquid conduit 10 is released by gravity, thus purging the device 100. No drop can leak when the bottle 3 and the refill 2 is uncoupled. .
