Description:
This application claims priority to FR Application No. 2004465 filed 5 May 2020, the entire contents of which is hereby incorporated by reference. 
     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to the field of beverage dispensing devices, and more particularly concerns a beverage dispensing device for successively dispensing two beverages. 
     Description of the Related Art 
     In a context of the fight against pathologies such as obesity and diabetes, there are beverage dispensing devices configured to reduce the consumption of sugar or flavor enhancers while guaranteeing an equivalent taste sensation. For example, a liquid dispensing apparatus is known from international PCT application WO2018/234275 A1 that allows for the alternating suction of two types of beverages from two containers, one of which contains a flavor enhancer absent from the second or present in a relatively different amount. 
     However, such devices do not guarantee accurate dosing and in particular are not user-friendly to fill. 
     There is therefore a need for a beverage dispensing device that is accurate and easy to use. 
     The Applicant therefore proposes to meet this need by using a beverage dispensing device comprising two containers, one of which is movable relative to the other, each comprising a beverage, and equipped with closure control means, so as to control the dispensing of the beverage from the second container in such a way as to allow for the successive dispensing of two beverages without mixing. 
     SUMMARY OF THE INVENTION 
     The object of the present invention is therefore a beverage dispensing device, characterized in that it comprises a main container, comprising a bottom and a side wall extending from the bottom towards an upper face, a beverage receiving cavity being formed in the main container, extending from the bottom and opening onto the upper face, the bottom of the beverage receiving cavity communicating with a channel circulating in the main container, the channel providing a communication between the bottom of the beverage receiving cavity and a fluid suction nozzle protruding from the upper face of the main container to enable a user to suck fluid contained in the beverage receiving cavity of the main container through the suction nozzle, a secondary container adapted to be movable within the beverage receiving cavity of the main container, the secondary container comprising a beverage receiving cavity opening on an upper face of the secondary container, at least one hole being formed in the bottom of the beverage receiving cavity of the secondary container, the beverage dispensing device comprising communication providing means between the interior of the beverage receiving cavity of the secondary container and the interior of the beverage receiving cavity of the main container and the channel of the main container, said communication providing means being configured so that when the secondary container is in the beverage receiving cavity of the main container, between an upper position of the secondary container and an open position of the secondary container, the at least one hole formed in the bottom of the beverage receiving cavity of the secondary container is plugged, and between the open position and a lower position of the secondary container in which the secondary container touches the bottom of the beverage receiving cavity of the main container, the at least one hole is not plugged. 
     The device allows for the successive dispensing of two beverages without mixing. 
     Thus, the open position is the position from which the at least one hole of the secondary container is no longer plugged, enabling the communication between the beverage receiving cavity of the secondary container and the beverage receiving cavity of the main container in order to suck the beverage contained in the beverage receiving cavity of the secondary container through the suction nozzle. 
     The upper position is preferably the position in which the upper face of the secondary container is flush with the upper face of the main container. However, it is also possible to envision the upper position above the open position, without the two upper faces necessarily matching. 
     According to one embodiment, the secondary container comprises a single hole and the bottom of the beverage receiving cavity of the secondary container is inclined towards the hole, the communication providing means comprise a ball configured to be received in the secondary container, the ball being sized to plug the hole of the secondary container, and the communication providing means also comprise a rod protruding into the beverage receiving cavity of the main container up to the open position, the rod being sized such that when the secondary container is between the open position and the lower position, the rod extends into the hole without plugging it and pushes the ball, preventing the ball from plugging the hole of the secondary container and thus enabling the communication between the secondary container and the main container. 
     The bottom is preferably funnel-inclined toward the hole, enabling the ball to fall in order to plug the hole. 
     The ball preferably has sufficient density such that the ball falls to the bottom of the hole, regardless of the beverage in the secondary container. 
     Thus, as liquid is sucked from the main container and the secondary container descends into the main container, the rod enables the ball to be dislodged from the hole from the time that the secondary container reaches the open position. 
     The invention is not limited in relation to the number of holes in the secondary container, the main container having to contain an equivalent number of rods, and the secondary container having to be inserted into the main container so that the hole in the secondary container is aligned with the rod as it descends. 
     According to one embodiment, a seal is received in a groove, provided at the hole level, at the level of the bottom of the beverage receiving cavity of the secondary container. 
     According to one embodiment, the communication providing means comprise at least one rod connected to the main container and protruding into the beverage receiving cavity of the main container in correspondence with the at least one hole, and the at least one rod being sized such that, between the upper position and the open position, the at least one rod extends into the hole of the secondary container and completely plugs the corresponding at least one hole of the secondary container, and between the open position and the lower position, the at least one rod partially plugs the corresponding at least one hole of the secondary container, thereby enabling the communication between the secondary container and the main container. 
     According to one embodiment, the at least one rod comprises a step, such that when the secondary container is between the open position and the lower position, the step is partially in the beverage receiving cavity of the secondary container, thus enabling the communication between the secondary container and the main container. 
     According to one embodiment, the communication providing means comprise a single rod and a corresponding single hole of the secondary container. 
     According to one embodiment, the rod is centered with respect to the beverage receiving cavity of the main container and extends into the channel. This makes it easy for the user to place the secondary container into the main container. 
     According to one embodiment, the bottom of the beverage receiving cavity is inclined, in particular funnel-inclined, toward the hole. 
     This facilitates the flow of beverages, and the ball is forced by gravity to plug the through hole. 
     According to one embodiment, the beverage receiving cavity of the main container and the secondary container are cylindrical with the same generatrix, the secondary container being adapted to slide within the beverage receiving cavity of the main container. 
     According to one embodiment, the container is made of plastic material. 
     The main container can be formed of two portions, namely a lower portion comprising the bottom of said beverage dispensing device and an upper portion comprising the bottom of the beverage receiving cavity of the main container, the two portions being joined in a sealed manner in a horizontal plane in the position of the device placed on its bottom, the lower portion comprising at least a portion of the channel. In particular, the lower portion can carry the rod of the communication providing means. 
     According to one particular feature of the invention, the suction nozzle is straw-like. 
     According to one particular feature of the invention, at least one of the main container and the secondary container comprises filling markers. 
     Thus, it is possible for the user to fill the main container and the secondary container adequately, so that they function properly on the one hand, and to meet a prescribed dosage according to the type of liquid consumed, on the other hand.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to  FIG.  1   , it can be seen that a beverage dispensing device  1  according to a first embodiment of the present invention is shown. The beverage dispensing device  1  comprises a main container  2 , a secondary container  3 , communication providing means  4  and a fluid suction nozzle  5 . 
     The main container  2  comprises a bottom  6 , a side wall  7  and an upper face  8 . The main container  2  is hollow so as to have a channel  9  therein, as can be seen in  FIGS.  2 - 4   . 
     The main container  2  further comprises a beverage receiving cavity  10 . The beverage receiving cavity  10  extends from the upper face  8  toward the bottom  6 . The beverage receiving cavity  10  thus comprises an upper opening  11 , in the plane of the upper face  8 , walls  12  and a bottom  13 , as can be better seen in  FIGS.  2 - 4   . A hole  14  is also present at the level of the bottom  13  and is configured for enabling the communication between the beverage receiving cavity  10  and the channel  9 . 
     In  FIG.  1   , it can be seen that the main container  2  is substantially cylindrical in shape. It should be noted, however, that any geometry may be considered without departing from the present invention. In addition, the main container  2  may have ergonomic features and/or be equipped with gripping means, in particular one or more handles formed on the side wall  7  of the main container  2 . 
     The main container  2  is configured to hold a first liquid L 1  in the beverage receiving cavity  10  and in the channel  9 . 
     In  FIG.  1   , it can be seen that the fluid suction nozzle  5  is arranged at the level of the upper face  8  of the main container  2 . As can also be seen in  FIGS.  2 - 4   , the fluid suction nozzle  5  comprises a hollow cylinder  15 , open at both ends  16 ,  17  and extending from the upper face  8  of the main container  2 . The hollow cylinder  15  is in communication with the channel  9 , via one of its ends  16 . The second, free end  17  is intended to be inserted into the mouth of a user of the beverage dispensing device  1 . For this purpose, the second end  17  has chamfers  18 . 
     The fluid suction nozzle  5  is configured to suck any liquid found in the main container  2 . Due to the hole  14  present at the level of the bottom  13  of the beverage receiving cavity  10 , the portion of the liquid L 1  present in the channel  9  will be sucked before that present in the beverage receiving cavity  10 . 
     As can be seen in  FIGS.  1 - 4   , the fluid suction nozzle  5  is preferably of the straw type. However, it should be noted that the person skilled in the art will be able to envisage any other fluid suction nozzle structure, as long as it is configured to enable the liquid present in the main container  2  to be taken from the channel  9 . 
     The secondary container  3  comprises a lower face  19 , walls  20  and a upper face  21 . The secondary container  3  further comprises a beverage receiving cavity  22 . The beverage receiving cavity  22  extends from the upper face  21  toward the lower face  19 . The beverage receiving cavity  22  thus comprises a upper opening  23 , in the plane of the upper face  21 , walls  24  and a bottom  25 , as can be better seen in  FIGS.  2 - 4   . A hole  26  is also present at the level of the bottom  25  and is configured to enable the communication between the beverage receiving cavity  22  and the exterior. 
     The secondary container  3  is configured to receive and contain a second liquid L 2  in the beverage receiving cavity  22 . 
     The main container  2  and the secondary container  3  are configured and sized such that the main container  2  is adapted to receive the secondary container  3  in its beverage receiving cavity  10 , and are correspondingly configured such that the secondary container  3  is movable within the beverage receiving cavity  10  of the main container  2 . In addition, the secondary container  3  and the beverage receiving cavity  10  of the main container  2  are sized such that, in the state of the secondary container  3  as received in the beverage receiving cavity  10  of the main container  2 , the walls  20  of the secondary container  3  and the walls  12  of the beverage receiving cavity  10  of the main container  2  provide a seal such that liquid L 1  present in the beverage receiving cavity  10  of the main container  2  is prevented from entering between them. Thus, the secondary container  3  is sealingly movable at the level of its walls  20  in the beverage receiving cavity  10  of the main container  2 . Advantageously, as shown in  FIG.  1   , the secondary container  3  and the beverage receiving cavity  10  of the main container  2  are cylindrical and of the same generatrix, with the outer diameter of the secondary container  3  being substantially smaller than the inner diameter of the beverage receiving cavity  10 . 
     In the state of the secondary container  3  as received in the beverage receiving cavity  10  of the main container  2 , the hole enables the communication between the beverage receiving cavity  22  of the secondary container  3  on the one hand and the beverage receiving cavity  10  and the channel  9  of the main container  2  on the other hand. 
     In addition, the hole  26  of the secondary container  3  and the hole  14  of the main container  2  are arranged and sized in such a way that in the state of the secondary container  3  as received in the beverage receiving cavity  10  of the main container  2 , they are opposite each other. And in the state of the secondary container  3  resting on the bottom  13  of the beverage receiving cavity  10  of the main container  2 , the hole  26  of the secondary container  3  and the hole  14  of the main container  2  are in communication. For example, and as shown in  FIGS.  2 - 4   , the hole  26  of the secondary container  3  and the hole  14  of the main container  2  are centered and of the same diameter. 
     The secondary container  3  is made with such a geometry and of such a material that it is configured to float on a liquid L 1  contained in the beverage receiving cavity  10  of the main container  2 . The secondary container  3  can be made of a plastic material such as polycarbonate, acrylonitrile butadiene styrene, polyvinyl chloride or polyamide. Advantageously, the secondary container  3  is made of a material with a density of less than 1 (water at 4° C. being taken as the reference body). 
     The communication providing means  4  are configured to enable the communication between the interior of the beverage receiving cavity  22  of the secondary container  3  and the interior of the beverage receiving cavity  10  of the main container  2  and the channel  9  of the main container  2 . 
     According to a first embodiment shown in  FIGS.  1 - 4   , the communication providing means  4  comprises a ball  27 . The ball  27  is configured and sized so that, when received in the beverage receiving cavity  22  of the secondary container  3 , it plugs the hole  26  and thereby prevents the communication between the beverage receiving cavity  22  and the exterior. As can be better seen in  FIGS.  2 - 4   , the bottom  25  of the beverage receiving cavity  22  of the secondary container  3  is funnel-inclined from the walls  24  toward the hole  26  so as to force the ball  27  to come to plug the hole  26  by gravity. In addition, the fact that the bottom  25  of the beverage receiving cavity  22  of the secondary container  3  is inclined enables the second liquid to be guided toward the hole  26  to flow into it. Advantageously, the hole  26  is cylindrical. In this case, the ball  27  has a diameter larger than the hole  26 . Preferably, the ball is made of a material having a density greater than that of water, such as stainless steel. 
     In addition, advantageously and as shown in  FIGS.  2 - 4   , a seal  28  is received in a groove  29 , provided at the level of the peripheral area  30  of the hole  26 , located at the level of the bottom  25  of the beverage receiving cavity  22 . Thus, the sealing of the closure is guaranteed. 
     The communication providing means  4  according to the first embodiment shown in  FIGS.  1 - 4    also comprises a rod  31 . The rod  31  is arranged with a first end  32  at the level of the lower face  6  of the main container  2  and the rod  31  comprises a free end  33  extending toward the upper face  8  of the main container  2 , along the direction of the generatrix of the cylindrical beverage receiving cavity  10  of the main container  2 . As can be seen in  FIGS.  2 - 4   , the rod  31  is arranged centrally with respect to the hole  14  in the bottom  13  of the beverage receiving cavity  10 , is sized to extend through the channel  9 , through the hole  14  in the bottom  13  of the beverage receiving cavity  10  without plugging it, and is sized so that its free end  33  is within the beverage receiving cavity  10 , beyond the through hole  14  in the bottom  13  of the beverage receiving cavity  10 . 
     Due to the fact that, in the state of the secondary container  3  as received in the beverage receiving cavity  10  of the main container  2 , the hole  14  of the main container  2  and the hole  26  of the secondary container  3  face each other, the free end  33  of the rod  31  in this state also faces the hole  26  of the secondary container  3 . 
     The rod  31  is sized such that when the secondary container  3  rests on the bottom  13  of the beverage receiving cavity  10  of the main container  2 , it passes through the hole  26  of the secondary container  3  without closing it, and its free end  33  is in the beverage receiving cavity  22  of the secondary container  3 , beyond the hole  26  of the secondary container  3 , as shown in  FIG.  4   . 
     It can also be seen in  FIG.  3    that, for a position of the secondary container  3  near the bottom  13  of the beverage receiving cavity  10  of the main container  2 , the rod  31  is also sized such that its free end  33  is in the beverage receiving cavity  22  of the secondary container  3 , beyond the hole  26  of the secondary container  3 . 
     Generally, the communication providing means  4  of the beverage dispensing device  1  according to the present invention are configured so that, in the state of the secondary container  3  as received in the beverage receiving cavity  10  of the main container  2 , they prevent/allow the communication between the beverage receiving cavity  22  of the secondary container  3  on the one hand, and the beverage receiving cavity  10  and the channel  9  of the main container  2  on the other hand, that is, they prevent/allow dispensing of the second liquid L 2  from the secondary container  3  toward the main container  2 . 
     According to the first embodiment, the ball  27  and the rod  31  of the communication providing means  4  are configured to interact so as to enable the communication between the beverage receiving cavity  22  of the secondary container  3  and the beverage receiving cavity  10  and the channel  9  of the main container  2 , as explained below. 
     Thus, as can be seen in  FIG.  3   , when the secondary container  3  is at such a distance from the bottom  13  of the beverage receiving cavity  10  of the main container  2  that the free end  33  of the rod  31  is in the beverage receiving cavity  22  of the secondary container  3 , beyond the hole  26  of the secondary container  3 , the ball  27  is pushed by the free end  33  of the rod  31 . This position of the secondary container  3  in the main container  2  corresponds to a so-called open position. The fact that the rod  31  extends into the beverage receiving cavity  22  of the secondary container  3  beyond the hole  26  of the secondary container  3 , prevents the ball  27  from plugging the hole  26  of the secondary container  3 . This has the effect, up to the position where the secondary container  3  rests on the bottom  13  of the beverage receiving cavity  10  of the main container  2 , of enabling the communication between the beverage receiving cavity  22  of the secondary container  3  and the beverage receiving cavity  10  of the main container  2 , thus allowing the second liquid L 2  to be dispensed from the secondary container  3  toward the main container  2 . 
     Due to the communication providing means  4 , the beverage dispensing device  1  according to the present invention comprises a dispensing range of first liquid and a dispensing range of second liquid. 
     A dispensing range of first liquid is defined as the range of movement of the secondary container  3  in the beverage receiving cavity  10  of the main container  2 , between an upper position of the secondary container  3  in the beverage receiving cavity  10  of the main container  2 , with the upper face  21  of the secondary container  3  being flush with the upper face  8  of the main container  2 , and an open position of the secondary container  3  with contact between the ball  27  and the free end  33  of the rod  31 . In this range, the hole  26  of the secondary container  3  is plugged by the ball  27 . Only the first liquid L 1  contained in the main container  2  (either in the channel  9  and totally or partially in the beverage receiving cavity  10 , or only in the channel  9 ) can be sucked by the user through the fluid suction nozzle  5 . 
     A dispensing range of second liquid is defined as the range of movement of the secondary container  3  in the beverage receiving cavity  10  of the main container  2 , between a position lower than the open position, in which the free end  33  of the rod  31  pushes the ball  27  and the ball  27  no longer plugs the hole  26  of the secondary container  3 , and a lower position of the secondary container  3  in which the secondary container  3  rests on the bottom  13  of the beverage receiving cavity  10  of the main container  2 . In this range, the beverage receiving cavity  22  of the secondary container  3  is either in communication with the beverage receiving cavity  10  of the main container  2  or in communication with the channel  9  of the main container  2 . The second liquid L 2  can thus be sucked by the user after the first liquid L 1 . It should be noted that the open position can correspond to the lower position. 
     Referring to  FIGS.  5 - 6   , it can be seen that a beverage dispensing device  101  according to a second embodiment of the present invention is shown. The beverage dispensing device  101  is similar to the beverage dispensing device  1  according to the first embodiment described above. Elements of the beverage dispensing device that are identical or similar to the elements of the beverage dispensing device of the first embodiment, and described with reference to  FIGS.  5 - 6   , will bear the same reference numerals increased by 100, and will not be described further here. 
     As before, the beverage dispensing device  101  comprises a main container  102 , a secondary container  103 , communication providing means  104  and a suction nozzle  105 . 
     According to the second embodiment, the communication providing means  104  comprises a rod  34 . The rod  34  is arranged with a first end  35  at the level of the lower face  106  of the main container  102  and the rod  34  comprises a free end  36  extending toward the upper face  108  of the main container  102 . As can be seen in  FIGS.  5 - 6   , the rod  34  is preferably centrally arranged. The rod  34  is sized so that its free end  36  is within the beverage receiving cavity  110 . 
     As can be seen in  FIGS.  5 - 6   , the rod  34  is arranged laterally and adjacent to the hole  37  in the bottom  38  of the beverage receiving cavity  110  of the main container  102 . 
     The rod  34  comprises a lower portion  39  and an upper portion  40 . The rod  34  is sized such that the lower portion  39  has a smaller thickness than the upper portion  40 , from a step  41 . In fact, in  FIGS.  5 - 6   , it can be seen that the rod  34  has a right-angle step  41  at the level of the interface between the lower portion  39  and the upper portion  40 . The step  41  is located in the beverage receiving cavity  110  of the main container  102  and opposite the hole  37  in the bottom  38  of the beverage receiving cavity  110  of the main container  102 . 
     It should be noted that the person skilled in the art will know of envisaging other geometries, such as a linear or curved thickness reduction, between the upper portion  40  and the lower portion  39  of the rod  34 , provided that at least a portion of the rod with reduced thickness is located within the beverage receiving cavity  110  of the main container  102  and opposite the hole  37  in the bottom  38  of the beverage receiving cavity  110  of the main container  102 . 
     The rod  34  and the secondary container  103  are configured and sized such that in the state of the secondary container  103  as received in the beverage receiving cavity  110  of the main container  102 , the rod  34  is received in the hole  126  of the secondary container  103 . In addition, the rod  34 , over its entire upper portion  40 , plugs the hole  126  of the secondary container  103  in a sealing manner, while allowing the secondary container  103  to sealingly slide along the rod  34 . 
     It can be seen in  FIG.  6    that the rod  34  is sized such that when the secondary container  103  rests on the bottom  113  of the beverage receiving cavity  110  of the main container  102 , it passes through the hole  126  of the secondary container  103 , with the upper portion  40  thereof in the beverage receiving cavity  122  of the secondary container  103 , beyond the hole  126  of the secondary container  103 , and with the lower portion  39  thereof, and thus the step  41 , partially in the hole  126  of the secondary container  103 . Thus, due to the lower portion  39  being partially within the hole  126  of the secondary container  103 , the latter is not plugged, thereby enabling the communication between the beverage receiving cavity  122  of the secondary container  103  and the channel  109  of the main container  102 . The second liquid L 2  can thus be sucked by the user after the first liquid L 1 . 
     In addition, the rod  34  is sized such that, for a secondary container  103  position near the bottom  113  of the beverage receiving cavity  110  of the main container  102 , the step  41  is also in the beverage receiving cavity  122  of the secondary container  103 . 
     In other words, as long as the upper portion  40  of the rod occupies all of the hole  126  of the secondary container  103 , the upper portion  40  of the rod  34  plugs the hole  126  of the secondary container  103 , thereby preventing the communication between the beverage receiving cavity  122  of the secondary container  103  and the channel  109  of the main container  102  and thereby preventing the second liquid L 2  from being sucked by the user. Only the first liquid L 1  contained in the main container  102  (either in the channel  109  and in the beverage receiving cavity  110 , or only in the channel  109 ) can be sucked by the user through the suction nozzle  105 . This concerns the dispensing range of first liquid. 
     And, once the upper portion  40  of the rod  34  is entirely beyond the hole  126  of the secondary container  103 , that is, the step  41  is beyond the hole  126  of the secondary container  103 , the upper portion  40  of the rod  34  no longer plugs the hole  126  of the secondary container  103 , and the lower portion  39  enables the communication between the beverage receiving cavity  122  of the secondary container  103  and the channel  109  of the main container  102  and thus allowing the second liquid L 2  to be sucked by the user after the first liquid L 1 . This concerns the dispensing range of second liquid. 
     The operation of the beverage dispensing device  1  according to the first embodiment will be described below, with reference to  FIGS.  2 - 4   . 
     Initially, the user pours a first liquid L 1 , for example water, into the main container  2 , through the upper opening  11 . The liquid L 1  then flows into the beverage receiving cavity  10  and then through the hole  14  into the channel  9 . 
     Second, the user places the ball  27  in the secondary container  3 . Due to the inclination of the funnel-shaped bottom  25  of the beverage receiving cavity  22 , the ball plugs the hole  26  in the bottom  25  of the beverage receiving cavity  22 . A second liquid L 2 , of a type different than the first liquid L 1 , such as a sweetened beverage, is poured into the secondary container  3  through the upper opening  23 . As the ball  27  plugs the hole  26  in the bottom  25 , the liquid L 2  is held in the secondary container  3 . 
     The user then places the secondary container  3  into the beverage receiving cavity  10  of the main container  2  via the upper opening  11 . It is understood that the secondary container  3  can be placed beforehand, with the ball  27  in it, in the beverage receiving cavity  10  of the main container  2  before the second liquid L 2  is poured in. Due to the ball  27  plugging the hole  26 , the second liquid L 2  does not mix with the first liquid L 1 . 
     Due to the geometry and density of the secondary container  3 , it floats on the surface of the first liquid L 1 , as can be seen in  FIG.  2   . It is preferable not to completely fill the beverage receiving cavity  10  of the main container  2  with the first liquid L 1  so as to leave a free volume at the level of the upper opening  11  which is sufficient to stably insert the secondary container  3 . Likewise, the first liquid L 1  will be filled sufficiently so that the secondary container  3  is within the dispensing range of first liquid, that is, the secondary container  3  is in a position in the beverage receiving cavity  10  of the main container  2  such that the free end  33  of the rod  31  is not in contact with the ball  27 . 
     Advantageously, the beverage receiving cavity  10  of the main container  2  can comprise filling markers. 
     When the user sucks on the suction nozzle  5 , a vacuum is created and thus the first liquid L 1  is sucked in, at first the first liquid L 1  present in the channel  9  of the main container  2  and then the first liquid L 1  present in the drink receiving cavity  10  of the main container  2 . The level of the liquid L 1  in the beverage receiving cavity  10  of the main container  2  is lowered, and thereby the secondary container  3  is lowered concomitantly. From the starting position of the secondary container  3  and until the free end  33  of the rod  31  contacts the ball  27 , that is, as long as the secondary container  3  is in the dispensing range of first liquid L 1 , only the first liquid L 1  is consumed by the user. 
     Once enough of the first liquid L 1  is sucked to lower the secondary container  3  such as it enters into the dispensing range of second liquid, either for a position lower than the open position, or a position in which the ball  27  contacts the free end  33  of the rod  31 , the free end  33  of the rod  31  pushes the ball  27  into the beverage receiving cavity  22  of the secondary container  3 . Since the beverage receiving cavity  22  of the secondary container  3  is in communication with the beverage receiving cavity  10  of the main container  2 , the suction of the first liquid L 1  leads to the suction thereafter of the second liquid L 2 , until it is completely consumed, as can be seen in  FIGS.  3  and  4   . 
     The operation of the beverage dispensing device  101  according to the second embodiment will be described below, with reference to  FIGS.  5 - 6   . 
     The operation of the beverage dispensing device  101  according to the second embodiment is similar to that of the beverage dispensing device  1  according to the first embodiment. 
     A first liquid L 1  is poured into the beverage receiving cavity  110  of the main container  102 . 
     Then, the user arranges the secondary container  103  in the beverage receiving cavity  110  of the main container  102 , as can be seen in  FIG.  5   . As before, it is preferable not to completely fill the beverage receiving cavity  110  of the main container  102  with the first liquid L 1  so as to leave a free volume at the level of the upper opening  111  sufficient to stably insert the secondary container  103 . Similarly, the first liquid L 1  will be filled sufficiently so that the secondary container  103  is in the dispensing range of first liquid, that is, the secondary container  103  is in the upper position, that is, the position where the upper portion  40  of the rod  34  occupies the entire hole  126  of the secondary container  103 . Advantageously, the beverage receiving cavity  110  of the main container  102  can comprise filling markers. 
     Suction of the first liquid L 1  leads to the lowering of the secondary container  103 . From the starting position of the secondary container  103  and as long as the upper portion  40  of the rod  34  occupies the entire hole  126  of the secondary container  103 , that is, as long as the secondary container  103  is within the dispensing range of first liquid L 1  and up to the opening position, only the first liquid L 1  is consumed by the user. 
     Once a sufficient quantity of the first liquid L 1  is sucked to lower the secondary container  103  such that it enters into the dispensing range of second liquid, that is, for a position of the secondary container  103  lower than the open position, that is, a position in which the upper portion  40  of the rod  34  is entirely beyond the hole  126  of the secondary container  103 , with the step  41  being beyond the hole  126  of the secondary container  103 , the sucking of the first liquid L 1  leads to the sucking of the second liquid L 2  thereafter, as can be seen in  FIG.  6   . 
     Thus, with the beverage dispensing device  1 ;  101  according to the present invention, throughout the consumption process up to the open position, the first liquid L 1  and the second liquid L 2  do not mix. 
     In addition, the beverage dispensing device  1 ;  101 , for an equivalent amount of liquid, allows for consumption of fewer products harmful to health. Indeed, in the case of sweetened beverages, the fact of drinking a volume of water and then a smaller volume of sweetened beverage in sequence, ending with the sweetened beverage, leads, thanks to the retro-olfaction phenomenon, to the user feeling a feeling of satisfaction equivalent to the one felt after having consumed the same quantity of sweetened beverage. 
     It should be noted that the main container  2 ;  102  and the secondary container  3 ;  103  can be configured such that the walls  20 ;  120  of the secondary container  3 ;  103  and the walls  12 ;  112  of the beverage receiving cavity  10 ;  110  of the main container  2  are spaced apart from each other, as long as they allow for the systematic insertion of the rod  31 ,  34  into the hole  26 ;  126  of the secondary container  3 ;  103 . 
     It should be noted that the beverage dispensing device can comprise more than one rod, the secondary container then comprising an equivalent number of holes, these being arranged in a corresponding manner. In the case of the first embodiment, the bottom may be partitioned into compartments partitioned from each other for this purpose, each having a bottom inclined as a funnel toward a hole and into which a ball is received. 
     A means for guiding the secondary container in the beverage receiving cavity of the main container, for example of the rib/groove or foolproof type, may also be envisaged so as to guide each hole of the secondary container systematically toward a corresponding rod. 
     In addition, the rod of the matching means is not necessarily centered, as long as the hole of the secondary container is correspondingly arranged. 
     It should also be noted that the embodiments are shown by way of illustration and that the rod of the communication providing means is not limitative. The person skilled in the art will be able to envisage other means, as long as they open into the beverage receiving cavity of the main container and are configured to enable the communication between the secondary container and the main container. 
     Advantageously, the beverage receiving cavity  22 ;  122  of the secondary container  3 ;  103  can comprise fill markers. 
     Advantageously, the beverage dispensing device  1 ;  101  is made of plastic. 
     It is understood that the embodiments just described have been given by way of indication and are not limitative, and that embodiments may be added thereto without departing from the scope of the present invention. 
     For production convenience, the main container  2  can be made in two portions as can be seen in  FIGS.  7  and  8   , namely:
         a lower portion  2 ′ comprising the bottom  6  and the horizontal portion of the channel  9 ; and   an upper portion  2 ″ comprising the bottom  13 , the two portions being joined in a sealing manner by screwing in a horizontal plane P (see  FIG.  7   ).       

     As can be seen in  FIG.  8   , the portion  2 ′, on its upper face opposite the bottom  6 , comprises an oblong recessed portion  50  for the formation of the horizontal portion of the channel  9 , the inner side wall of which comprises a step  51  on which a seal  52  is intended to be placed. 
     The rod  31 , the role of which has been indicated above, stands from the bottom of the recessed portion  50 . 
     In the example shown, the portion  2 ′ is pierced in four places evenly distributed near its edge for the passage of screws  53  passing vertically through it for fixing said portion  2 ′ to the portion  2 ″, which has holes for receiving the screws  53  in its lower wall. 
     For assembly, the portions  2 ′ and  2 ″ are applied one on top of the other in the plane P and the screws  53  are introduced and put in place through the bottom  6 .
