Description

[0001] DESCRIPTION

[0002] TITLE: Beverage dispensing device

[0003] Technical field of the invention

[0004] The invention relates to a device and an assembly for dispensing beverages, such as beer, for example.

[0005] State of the prior art

[0006] Document WO 2016 / 166475 in the name of the Applicant discloses a beverage dispensing assembly for filling a container, in particular a glass, via a nozzle passing through a sealing element housed in the bottom of the container.

[0007] The nozzle is connected to a tank, for example a barrel, via a solenoid valve which can be controlled between an open position allowing the container to be filled, and a closed position.

[0008] Such a distribution set is intended for professionals and has a relatively high cost.

[0009] Document WO 2020 / 234543, also in the name of the Applicant, proposes a distribution device adapted to the needs of the general public and presenting a lower cost.

[0010] This beverage dispensing device comprises a base intended to be fixedly mounted on a reservoir containing a fluid, in particular a beverage, a fluid dispensing nozzle movable in translation along an axis relative to the base, the nozzle comprising a sampling part and a fluid dispensing part. The sampling part is capable of actuating the opening of a valve by translational movement of said sampling part, the sampling part and the dispensing part being fluidically connected by a fluid circulation channel opening at the sampling part and the dispensing part, respectively by at least a first opening and at least a second opening.The nozzle comprises a bearing surface, the dispensing device further comprising a lever capable of pivoting around an axis fixed relative to the base, said lever comprising an actuating part and a bearing part bearing on said bearing surface of the nozzle, so that the pivoting of the lever actuates the translational movement of the nozzle.

[0011] The lever and the bearing surface thus act in the manner of a cam, the contact area between the lever and the bearing surface moving progressively when the lever is actuated. The actuation of the lever, that is to say its rotation around the fixed axis, causes the axial translational movement of the nozzle and, consequently, the opening or closing of the valve with which the sampling part cooperates.

[0012] The device may also comprise means for pressurizing the fluid reservoir, said pressurizing means comprising a pressurized gas reservoir and a channel for supplying pressurized gas into the fluid reservoir, connected to a pressurized gas reservoir formed for example by a commercial cartridge.

[0013] There is now a need to secure and facilitate the release of pressurized gas in the fluid reservoir, when it is attached to the beverage dispensing device.

[0014] Presentation of the invention

[0015] To this end, the invention relates to a beverage dispensing device comprising a base intended to be fixedly mounted on a reservoir containing a fluid, a fluid dispensing member comprising a fluid circulation channel opening at a first end intended to be supplied with fluid by the reservoir and at a second end intended to supply fluid to a container, means for pressurizing the reservoir, said pressurizing means comprising a pressurized gas reservoir and a channel for supplying pressurized gas into the reservoir, said channel comprising a closure member movable between a closed position of said channel and an open position of said channel, the base comprising means for fixing the gas reservoir, characterized in that the closure member comprises a part projecting outside the base,capable of being actuated when fixing the gas tank to the base by means of said corresponding fixing means, the actuation of said projecting part causing the closure member to move towards the open position when fixing the gas tank to the base.,

[0016] The fluid can be a beverage, for example beer.

[0017] In this way, the supply of pressurized gas into the tank can be carried out simultaneously with the fixing of the tank to the base, by actuating the projecting part, thus avoiding having to carry out the fixing and opening of the pressurized gas supply channel separately. This makes it easier and safer to use the beverage dispensing device.

[0018] Such a distribution device thus makes it possible to simply pressurize the contents of the tank when placing the base on said tank, quickly and securely.

[0019] The fluid distribution member is, for example, a distribution nozzle.

[0020] The container may comprise a bottom and a side wall delimiting the internal volume of the container, as well as a closure member formed in the bottom of the container, said support part of the container being formed by the bottom. The container may be similar to that described in document WO 2016 / 0166475 in the name of the Applicant.

[0021] The closure member can be returned to the closed position when the tank is not fixed to the base.

[0022] Such a feature makes it even easier to use the device while avoiding handling errors.

[0023] The closure member may comprise a valve mounted in a housing of the base, said housing belonging to the pressurized gas supply channel, said housing comprising a seat, said valve being movable between the closed position of said channel in which it is in sealed contact with the seat so as to prevent the passage of pressurized gas, and the open position of said channel in which it is spaced from said seat so as to allow the passage of pressurized gas.

[0024] Such a type of sealing organ is robust and has good durability.

[0025] The return of the closure member may be achieved by means of elastic return means mounted between the closure member, in particular the valve, and a fixed part of the base, in particular a bearing surface delimiting said housing. Said bearing surface may be located opposite the seat. The elastic return means may be a helical compression spring.

[0026] The projecting portion of the closure member may be formed by a rod extending from the valve and opening outside the base.

[0027] The rod is preferably straight and may extend along the axis of insertion or attachment of the reservoir. The reservoir may be cylindrical and the axis of insertion or attachment of the reservoir may correspond to the reservoir axis.

[0028] The valve may include a shoulder and an annular seal bearing on the shoulder and intended to provide a sealed bearing on the seat of the housing.

[0029] The seal is for example an O-ring. The seal is for example made of elastomer material.

[0030] The tank fixing means may include bayonet or quarter-turn fixing means, capable of cooperating with complementary tank means.

[0031] Alternatively, the fixing means may comprise screw fixing means, capable of cooperating with complementary means of the tank.

[0032] The device may further comprise a purge valve arranged to allow the purge of the gas contained in the liquid reservoir and / or in the pressurized gas reservoir, by manual action, bypassing the closure member.

[0033] Such a valve makes it possible to manually reduce the pressure in the tank(s) before dismantling them, simply and quickly. The invention also relates to a fluid distribution assembly, characterized in that it comprises a device as above and a fluid tank, the fluid circulation channel being fluidically connected to the internal volume of the tank so as to allow fluid to be drawn off, the pressurized gas supply channel being capable of allowing pressurized gas to be supplied into the internal volume of the tank by opening the closure member.

[0034] The reservoir may comprise a cam surface in the general shape of a helix, capable of cooperating with the projecting part of the closure member, the relative rotation of the reservoir with respect to the base causing the translational movement of the closure member between its closed and open positions, by pressing and moving the projecting part on said cam surface.

[0035] Such an embodiment is particularly suitable in the case where the fixing means are bayonet or quarter-turn fixing means.

[0036] Alternatively, in the case where the tank is fixed to the base by screwing, the projecting part of the closure member may come to bear on a flat surface, extending perpendicular to the screwing axis, which may be the axis of the tank. In this way, as the screwing progresses, the closure member is moved in translation towards its open position, by pressing and sliding on said flat surface.

[0037] The cam surface may be formed on a cap, sealingly mounted on a tank body.

[0038] The cap may also include additional fixing means, intended to cooperate with the fixing means of the base. In particular, the cap may include attachment means for bayonet or quarter-turn fixing means.

[0048] Detailed description of the invention

[0049] Figures 1 and 2 illustrate a beverage dispensing assembly 1 according to one embodiment of the invention.

[0050] Said assembly 1 comprises a tank 2 intended to house a commercial reservoir 3, for example a cylindrical barrel 3 containing beer.

[0051] The tank 2 comprises a cylindrical side wall 4 and a bottom 5. The side wall 4 and the bottom 5 comprise, in their thickness, a material forming a thermal insulator.

[0052] The terms axial, radial and circumferential are defined relative to a central axis of the tank 2.

[0053] Blocks of heat transfer material 7, 8, comprising a casing or a reservoir containing a heat transfer liquid such as water, are housed in the tank 2. The blocks 7, 8 are pre-cooled before insertion into the tank 2.

[0054] In particular, a block 7 of generally circular shape is mounted at the bottom of the tank 2, the bottom of the reservoir 3 bearing on the upper surface of the circular block 7.

[0055] Furthermore, peripheral blocks 8 of concave shape are mounted in the tank 2, between the side wall 4 of the tank 2 and the side wall of the reservoir 3.

[0056] The side wall 4 of the tank 2 is equipped with a handle 9 fixed to studs 10 of the tank 2. The handle 9 makes it easier to transport the assembly 1.

[0057] The assembly 1 also comprises a cover 11 for closing the open upper end of the tank 2. The cover 11 comprises two lateral gripping zones 12 or handles, formed here by diametrically opposed hollow zones 12 of the cover 11. The cover 11 comprises a central circular housing or opening 13 oriented axially. Orifices 14 are formed around the central opening 13, the orifices opening 14 into the internal volume 15 of the tank 2.

[0058] The cover 11 further comprises a rib 16 extending axially and formed on the periphery of the central opening 13. The cover 11 further comprises a groove 17 extending axially and formed on the periphery of the central opening 13. The groove 17 is located, for example, diametrically opposite the rib 16.

[0059] The assembly 1 further comprises a beverage dispensing device 18, located in the internal volume 15 of the tank 2, close to the reservoir 3. The beverage dispensing device 18 is shown in more detail in Figures 3 to 6. The base 19 comprises a body 20 in which a central recess 21 is formed.

[0060] The device 18 also comprises a nozzle 25 in which a liquid circulation channel 30 is formed. A sampling part 31 (visible in FIGS. 8 and 10), in the form of a hollow rod, extends substantially axially from the body 20.

[0061] The free end of the rod 31 is intended to press on a flap or a valve 33, which may be part of the distribution device 18 or of the reservoir s, depending on the case.

[0062] When the valve 33 is pushed downwards, against a return force exerted by a return spring 35 of the reservoir 3, then the valve 33 is in the open position and the liquid contained in the reservoir 3 can escape through the orifice previously closed by the valve 33, as is known per se. Conversely, when no force is exerted downwards by the rod 31, the valve 33 is returned upwards by the return spring 35, so as to close the opening and prevent the flow of liquid. The valve 33 can also be returned upwards due to the pressure of the gas contained in the reservoir 3.

[0063] The sampling part 31 comprises a channel which opens at one end at the free end of the hollow rod, and at the other end into the liquid circulation channel 30 of the nozzle 25.

[0064] The nozzle 25 may be composed of several parts assembled together, for example by snap-fastening, and together defining the liquid circulation channel 30.

[0065] Alternatively, the nozzle 25 is made in one piece.

[0066] The nozzle 25 comprises a flat surface 32, facing upwards, extending in the radial plane, as well as a distribution part 37 projecting from this surface 32. It is recalled that the radial plane is a plane perpendicular to the axis.

[0067] The dispensing portion 37 has an opening 40 near its free end, as shown in FIG. 4. The free end of the dispensing portion 37 is hemispherical, frustoconical or ogive-shaped.

[0068] The nozzle 25 comprises an elongated rotational coupling portion 42, which projects axially from the planar surface 32, on the same side as the dispensing portion 37, said rotational coupling portion 42 being substantially parallel to the dispensing portion 37.

[0069] The rotating coupling part 42 is engaged in the groove 17 of the cover 11, so as to ensure the correct angular positioning of the cover 11 relative to the nozzle 25.

[0070] The device 18 further comprises a lever 43 in the general shape of a U, comprising a base from which two branches extend. The lever 43 is mounted in the orifice 21 in an articulated manner around a pivot axis passing through two projecting studs on either side of the base of the lever. The upper edges of the branches of the lever 43 each have a convex rounded shape, intended to form an actuation zone. The lever 43 bears on the flat surface 32 of the nozzle 25, between the pivot axis and the branches.

[0071] The pivoting of the lever 43 thus causes the translational movement of the nozzle 25 along the axis of the tank.

[0072] The assembly 1 also includes a container 48, visible in figures 1 and 2, comprising a circular bottom and a side wall delimiting an internal volume.

[0073] The bottom of the container 48 comprises, for example, a self-sealing deformable closure member made of elastomer, offset relative to the axis of the container (not shown).

[0074] The beverage dispensing device 18 is intended to be used with an initially non-pressurized reservoir 3, and pressurization means external to the reservoir 3.

[0075] The base 19 comprises on a lower face fixing means 50, shown in figures 5 and 6, allowing it to be fixed to the tank 3 or to the vessel 2 in a removable manner, as shown in figures 5 and 6. The fixing means 50 are for example bayonet fixing hooks, capable of interacting with complementary fixing means secured to the tank 3.

[0076] The complementary fixing means of the tank 3 may be an integral part of the body of the tank 3, or else be defined on a cap 51 fixed in a sealed manner on the tank 3, as shown in figure 6.

[0077] These additional fixing means are bayonet, quarter-turn or screw means, corresponding to the fixing means 50 of the base 19.

[0078] The base 19 is fixed to the cap 51 by a rotational movement around the main axis of the reservoir 3, for example by an angle between 45° and 90°.

[0079] Alternatively, the fixing means 50 may be quarter-turn fixings, or screw fixings.

[0080] The body 20 of the base 19 comprises an orifice 54 (figures 8 and 10) located at the level of the median plane of the body 20, said orifice 54 serving for mounting a gas supply pipe 55 connected to a pressurized gas tank 56, here a commercial cartridge, for example connected by screwing to an inlet 57 of the pipe 55.

[0081] The body 20 of the base 19 comprises, for example, an angled casing 90 radially surrounding the pipe 55 to protect it. The casing 90 is connected to a cylindrical element 91 radially surrounding the inlet 57 of the pipe 55, and mounted at one end of the angled casing 90. The pipe 55 extends through the casing 90 and the cylindrical element 91 in a U-shaped profile, the inlet 57 and the gas supply orifice 54 opening out in substantially parallel directions. The body 20 further comprises a tubular portion 58 extended by a dip tube 59 intended to be inserted into the reservoir 3. The lower end of the dip tube 59 comprises one or more openings allowing the suction of the liquid contained in the reservoir 3.

[0082] A pressurization channel 61 is formed in the tubular part 58 and opens at one or more orifices 62. The orifices 62 are intended to be housed in the tank 3, so as to pressurize the internal volume of said tank 3, using the pressurized gas coming from the pressurized gas tank 56.

[0083] According to the invention, a closure member 65 is arranged between the pressurization channel 61 and the orifice 54 for supplying gas from the gas reservoir 56.

[0084] The closure member 65 is movable between an open position of the channel 61, shown in FIG. 10, in which it allows the flow of gas from the orifice 54 into the channel 61, and a closed position of the channel 61, shown in FIG. 8, in which it blocks the flow of gas from the orifice 54 to the channel 61.

[0085] The closure member 65 comprises a housing 67 into which the orifice 54 and the pressurization channel 61 open and a seat 69 defined by the walls of the housing 67 around the opening of the pressurization conduit 61.

[0086] The housing 67 is for example formed by a substantially cylindrical perforation in the base 19, and closed by a screw 70.

[0087] The closure member 65 also comprises a valve 71 slidably mounted in the housing 65, said valve 71 comprising a rod 73 extending through the pressurization channel 61 which opens into the housing 67, as well as an elastic return member 74 disposed in the housing 67 and urging the valve 71 towards the seat 69.

[0088] The valve 71 comprises a radial shoulder 75 on which the elastic return member 74 bears, the shoulder carrying an O-ring 77 radially enclosing the rod 73 on the opposite side of the shoulder 75.

[0089] The return member 74 is thus mounted compressed between the shoulder 75 and an opposite surface of the housing 67, defined by the screw 70 in the example shown.

[0090] The elastic return member is, for example, a helical compression spring.

[0091] In the open position of the closure member 61, the valve 71 is moved towards the seat 69, so that the O-ring 77 comes into leaktight contact with the seat 69 and blocks the passage of gas from the housing 67 to the pressurization channel 61.

[0092] The rod 73 has a free end 79 which extends axially beyond the base 19 and forms a projecting portion outside the base 19, in the direction of the reservoir 3.

[0093] Advantageously, a second O-ring 80 encloses the rod 73 on the side of its free end 79, which makes it possible to prevent gas leaks when the closure member is in the open position. The free end 79 of the rod 73 is for example rounded, and comes to bear against a cam 81 extending on an upper surface of the reservoir 3, and plays a role of follower of the cam 81.

[0094] The cam 81 can be set on the cap 51 fixed to the reservoir 3, shown in Figures 7 and 9, or directly on the upper surface of the reservoir 3.

[0095] The cam 81 has a general helical shape, for example having a substantially constant slope, wound around the main axis at the bottom of a helical trench 82.

[0096] The helical trench 82 opens onto a flat part substantially perpendicular to the main axis.

[0097] The free end 79 of the rod 73 moves along the cam 81 during a rotational movement of the base 19 relative to the reservoir 3, around the main axis of the reservoir 3, when fixing the base on the reservoir 3.

[0098] The free end 79 of the rod 73 travels for example along the cam 81 when the base 19 performs a rotation of an angle between 45° and 90° around the axis, from a low position 83, shown in figure 7, to a high position 85, shown in figure 9.

[0099] During this path, the tracking of the cam 81 by the free end 79 causes an axial translational movement of the valve 71, which causes the closure member 65 to move from the closed position to the open position.

[0100] Conversely, when the base 19 is removed from the tank 3, the closure member 65 is urged towards its closed position by the return member 74, just as when the base 19 is not installed on the tank 3.

[0101] Thus, when using such a device 18, the reservoir 3 is pressurized using the pressurized gas contained in the reservoir 56, through the pipe 55, the orifice 54, the closure member 65, the pressurization channel 61 and the orifice(s) 62, when the base 19 is mounted on the reservoir 3.

[0102] When the base 19 is removed, the return member 74 automatically biases the closure member 65 toward its closed position, and prevents gas from escaping from the tank. In order to fill one of the containers 48, a user can grasp the container 48 and place the base at the central opening 13 of the lid 11 by aligning the closure member 53 with the dispensing portion of the nozzle 25. The user can then push the container 48 into the opening 13 so that the dispensing portion 37 penetrates into the internal volume of the container 48 through the closure member which deforms to allow such insertion. It will be noted that the closure member is designed to ensure a seal between the container 48 and the dispensing part 37 of the nozzle 25. When the dispensing part 37 is introduced into the internal volume of the container 48, the bottom of the container 48 comes into contact with the upper edges of the arms of the lever.From this position, when the user continues the downward movement of the container 48, the axial force exerted on the container 48 exerts a force on the lever 43 which tends to pivot it around its pivot axis. This causes a downward translational movement of the nozzle 25, so that the sampling rod 31 presses on the valve 33 and moves it towards its open position, against the return force exerted by the return spring 35 and / or against the force exerted by the gas contained in the tank 3.

[0103] The liquid contained in the reservoir 3 then successively passes through the orifices and the internal volume of the dip tube 59, the internal volume of the tubular part 58 of the body 20, then the distribution channel 30 of the nozzle 25 before emerging into the container 48 through the orifice 40 of the nozzle 25.

[0104] It will be noted that, at the time of opening of the valve 33, the opening 40 is entirely located in the internal volume of the container 48.

[0105] In order to stop the flow of liquid, the user releases the pressure exerted axially on the container 48, so that the nozzle 25 and the lever 43 are returned to their position, causing the valve 33 to close.

[0106] The full container 48 can then be removed upwards, the self-sealing element ensuring the sealing of the bottom of the container 48.

[0107] Such an assembly 1 is simple to implement and makes it possible to ensure, in a reliable and inexpensive manner, the filling of the containers 48.

[0108] According to a variant not shown, a dispensing pipe can be connected in a sealed manner to the dispensing nozzle 25, or completely replace the dispensing nozzle 25, in order to fill traditional containers such as glasses with an unpierced bottom. The dispensing pipe then makes it possible to fill the containers through their upper opening, in a known manner. The pipe can be rigid, for example of the swan neck type, or flexible. The lever 43 is then activated manually to allow the liquid to flow into the container, and can have a suitable shape to facilitate its manual activation.

[0109] A second embodiment of the device 18 is shown in Figures 11 and 12.

[0110] In this second embodiment, the body 20 of the base 19 does not include an angled casing 90 and consists solely of the cylindrical element 91 radially surrounding the pipe 55. The inlet 57 and the gas supply orifice 54 then open in directions perpendicular to each other. Such an arrangement makes it possible to simplify the base 19 and to reduce the quantity of materials required for manufacturing.

[0111] Also shown in Figures 11 and 12, the device 18 comprises a gas purge valve 92, which is for example arranged in alignment with the closure member 65.

[0112] The purge valve 92 is arranged to allow manual emptying of the gas contained in the tank 56 and / or in the internal volume of the tank 3, once the use of the device 18 is complete, before disconnecting the tank 56 and dismantling the distribution device 18. This makes it possible to avoid projections and incidents when dismantling the tank 56 and / or the device 18, by reducing the gas pressure beforehand.

[0113] As shown in Figure 12, the purge valve 92 comprises a rod 93 whose head 94 forms the bearing surface of the return member 74 of the closure member 65, as well as a manipulation ring 97 at its opposite end, outside the base 20. The purge valve 92 also comprises a return member 95, of the compression spring type, arranged to urge the head 94 towards its seat 96. When the head 94 is in sealed contact against the seat 96, the purge valve 92 is closed and allows the normal operation of the closure member 65. When the rod 93 is actuated against the effect of the return member 95 by manual action on the ring 97, the head 94 is moved away from the seat 96 and allows the passage of the gas contained in the tank 56 and / or in the internal volume of the tank 3 outwards, bypassing the closure member 65.

[0114] The pressure in the reservoir 56 and / or in the reservoir 3 then decreases continuously until the rod 93 is released.
