Description

DESCRIPTION

TITLE: Beverage dispensing device Technical field of the invention

The invention relates to a device and an assembly for dispensing a beverage, such as, for example, beer.

State of the prior art

Document WO 2016/166475 in the name of the Applicant discloses a beverage dispensing assembly making it possible to fill a container, in particular a glass, by means of a nozzle passing through a sealing element housed in the bottom of the container.

The nozzle is connected to a reservoir, 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.

Such a distribution assembly is intended for professionals and has a relatively high cost.

There is currently a need to be able to offer a distribution assembly adapted to the needs of the general public and having a lower cost.

Presentation of the invention

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 nozzle movable in translation along an axis relative to the base, the nozzle comprising a sampling part and a fluid distribution part, said sampling part being able to actuate the opening of a valve by translational movement of said sampling part, the sampling part and the dispensing part being fluidly connected by a fluid circulation channel opening at the level of the sampling part and of the dispensing part, respectively through at least one first opening and at least one second opening, the nozzle comprising a bearing surface, the dispensing device comprising furthermore, a lever capable of pivoting about an axis fixed relative to the base, said lever comprising an actuating part and a part bearing resting on said bearing surface of the nozzle, so that the pivoting of the lever actuates the translational movement of the nozzle. The valve may belong to the reservoir or to the device.

The lever and the bearing surface thus act in the manner of a cam, the contact zone between the lever and the bearing surface gradually moving during actuation of the lever. The actuation of the lever, that is to say its rotation around the fixed axis, causes the displacement axial in translation of the nozzle and, therefore, the opening or closing of the valve with which the sampling part cooperates.

The nozzle may include at least a first part defining a first part of the fluid circulation channel and forming the sampling part, and at least a second part defining a second part of the fluid circulation channel and forming the distribution part, the the first part and the second part of the nozzle being assembled in a sealed manner to one another.

The second part can be a standard element, marketed with the reservoir and reused so as to form the second part of the nozzle.

The nozzle may include at least a third part defining a third part of the circulation channel and mechanically and fluidly connecting the first and second parts.

The different parts of the nozzle can be fixed relative to each other by snap-fastening.

Such a structure makes it possible to facilitate the manufacture, assembly and cleaning of the nozzle.

It will be noted that the structure and operation of a tank equipped with a valve is known from the prior art, for example from document EP 2 001 790.

Such a valve, also called a valve, is movable in translation between a closed position and an open position. An elastic return means, for example a compression spring, returns the valve to the closed position.

The force exerted by the return means on the valve can also allow the nozzle to be returned to a rest position of the nozzle, in which no force is exerted on the lever. As a variant, the nozzle can be returned to this rest position by a return means distinct from that associated with the valve of the reservoir.

The reservoir may conventionally include a dip tube extending into the reservoir between a first end connected to the orifice closed by the valve and a second end located near the bottom of the reservoir, opposite the valve. In this way, the drink is taken from the bottom of the tank and then rises through the dip tube before escaping through the orifice at the top of the tank, when the valve is open.

The nozzle, the base and / or the lever can be made of plastic, for example by injection. The dispensing part may have a free end of hemispherical, frustoconical or ogive shape.

The side wall can be cylindrical, the bottom being circular.

The cylindrical side wall and / or the bottom may include a material forming a thermal insulator.

The cover may include means for centering the container, in particular means for centering the part forming the bottom of the container. Said centering means may comprise a housing or an opening formed in the cover and the shape of which corresponds substantially at the bottom of the container. Such centering means make it possible to facilitate the positioning of the dispensing part of the nozzle relative to the container.

The second opening of the dispensing part of the nozzle may have an angular orientation determined about an axis of the dispensing part, the nozzle and / or the cover comprising means for angular positioning of the nozzle relative to the cover. Said angular positioning means may include a protruding portion extending from the nozzle or from an element rotatably coupled to the nozzle, cooperating with a recessed portion of complementary shape provided in the cover, or vice versa. Said protruding portion and said recessed portion may extend along the axis of translation of the nozzle so as to ensure coupling regardless of the axial position of the nozzle relative to the cover.

The closure member can be offset relative to the axis of the container, said container comprising means for angular positioning of the container relative to the cover or relative to the nozzle.

Said angular positioning means may include a recessed portion formed in the container and cooperating with a projecting portion extending from the cover or from the nozzle, or vice versa.

Such ribs make it possible to center the reservoir on the axis of the tank, in particular when the latter has a generally cylindrical shape.

The centering and positioning means may include an annular rim formed at the bottom of the tank, the reservoir being intended to come to rest on said rim, along the axis of the tank. Such a rim makes it possible to position the reservoir axially, so as to adjust its axial position, in particular with respect to the sampling part of the nozzle.

The cover may include at least one orifice communicating with the internal volume of the tank, located around the zone intended to receive the container. Several holes of this type can be distributed around the axis of the cover. These orifices are intended to allow the flow of the beverage into the tank in the event of the container being overfilled, for example.

The tank may include cooling means distributed at the level of the side wall or the bottom of the tank, housed in the internal volume of the tank. The cooling means may be blocks filled with a heat transfer material, for example a bag or a reservoir containing a heat transfer liquid such as water. These blocks are suitable for being cooled beforehand before introduction into the tank.

A circular block can be housed in the bottom of the tank.

The block located at the bottom of the tank may form part of the means for positioning and centering the tank. In particular, a part of the reservoir, for example the bottom of the reservoir, can bear axially on the block located at the bottom of the tank.

Blocks can be distributed over the internal surface of the side wall, for example between the aforementioned ribs of the centering and positioning means.

The assembly or the device may include means for pressurizing the reservoir, said pressurizing means comprising a reservoir of pressurized gas and a channel for supplying the pressurized gas into the reservoir.

Detailed description of the invention

Figures 1 to 18 illustrate a beverage dispensing assembly 1 according to one embodiment of the invention.

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

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.

As can be seen in FIG. 6, the ribs 6 extending along the X axis of the tank 2 are formed at the level of the internal surface of the side wall 4. The ribs 6 are here three in number and are regularly distributed around the circumference.

The terms axial, radial and circumferential are defined with respect to the X axis.

The dimensions of the ribs 6 are adapted so as to allow the reservoir 3 to be centered, the outer wall of which bears on the tops, that is to say the radially internal parts, of the ribs 6.

Blocks of heat transfer material 7, 8, comprising an envelope or a tank containing a heat transfer liquid such as water, are housed in tank 2. Blocks 7, 8 are cooled beforehand before insertion into tank 2.

In particular, a block 7 of generally circular shape is mounted at the bottom of tank 2, the bottom of tank 3 resting on the upper surface of circular block 7.

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 tank 3. The peripheral blocks 8 are mounted circumferentially between the ribs 6.

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 facilitates the transport of the assembly 1.

The assembly 1 also includes a cover 1 1 for closing the open upper end of the tank 2. The cover 1 1 has two lateral gripping zones. 12 or handles, formed here by diametrically opposed recessed areas 12 of the cover 1 January. The cover 1 1 comprises a housing or a central circular opening 13 of axis X. Orifices 14 are formed around the central opening 13, the orifices 14 opening into the internal volume 15 of the tank 2.

The cover 1 1 further comprises a rib 16 extending axially and formed on the periphery of the central opening 13. The cover 1 1 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 opposed to the rib 16.

The assembly 1 further comprises a beverage dispensing device 18, located in the internal volume 15 of the tank 2, near the tank 3.

The

The base 19 comprises a body 20 in which is formed a central recess 21, a central hole 22 of axis X and lateral pivoting zones 24, located on either side of a median plane passing through the X axis. .

The device 18 furthermore comprises a nozzle 25 composed of three distinct parts, namely an upstream part 26, a middle part 27 and a downstream part 28. The terms upstream and downstream are defined with respect to the direction of circulation of the liquid through the nozzle 25.

The upstream part 26, illustrated in Figures 10 and 11 comprises a body 29 in which is formed a liquid circulation channel 30. A sampling portion 31 in the form of a hollow rod 31 of axis X s' extends from body 29.

The free end of the rod 31 is intended to come to press on a valve or a valve, not shown, of the reservoir 3. When the valve is pushed down, against a return force exerted by a spring. return of the reservoir 3, then the valve is in the open position and the liquid contained in the reservoir 3 can escape through the orifice previously closed by the valve, as is known per se. Conversely, when no force is exerted downwards by the rod 31, the valve and the upstream part 26 are biased upwards by the return spring, so as to close the opening and prevent the opening. liquid flow. The valve and the upstream part 26 can also be returned upwards due to the pressure of the gas contained in the reservoir 3.

The channel of the sampling part 31 opens at a first end at the level of the free end of the hollow rod, and at the other end in the channel 30 of the body 29. The body 29 comprises a flat surface 32, facing towards the top, extending in the radial plane. Remember that the radial plane is a plane perpendicular to the X axis.

The middle part 27, illustrated in FIG. 13, comprises a body 33 comprising a channel having a first part 34 formed in a connector 35, and a second part 36 delimited by a ratchet flange 37. The connector 35 is so engaged. sealed by snap-fastening in the channel 30 of the body 29 of the upstream part 26. The downstream part 28, illustrated in FIG. 14, comprises a body 36 from which extends a hollow elongate distribution part 37, with an axis parallel to the X axis, delimiting a first part of a channel, opening into a second part 38 of the channel, extending radially and delimited by a latching rim 39 able to cooperate with the latching rim 37 of the middle part 27, so as to ensure a sealed fixing of the downstream part 28 on the part median 28, as illustrated in Figures 14 and 15. The dispensing portion 37 has an opening 40 near its free end. The opening 40 is oriented in a radial plane and along an axis forming an angle α with the radial direction (figure 14), that is to say with the straight line formed in the radial plane and passing through the center of the part. distribution 37 and by the X axis.

The free end 41 of the dispensing portion 37 is hemispherical, frustoconical, or bullet-shaped.

An elongated rotational coupling portion 42 extends axially from the body 36, on the same side as the dispensing portion 37, said rotational coupling portion 42 being parallel to the dispensing portion 37.

The rotational coupling portion 42 is engaged in the groove 17 of the cover 1 1, so as to ensure the correct angular positioning of the cover 1 1 relative to the nozzle 25, as is best seen in FIG. 7.

The device 18 further comprises a lever 43 in the general shape of a U, better visible in FIG. 16, comprising a base 44 from which extend two branches 45. The base 44 comprises two coaxial lateral studs 46 coming into engagement. in the lateral pivoting zones 24 of the base 19 so as to allow the pivoting of the lever 43 relative to the base 19, around the axis passing through the studs 46.

The upper edges 47 of the branches 45 each have a rounded convex shape, intended to form an actuation zone. The lever 43 rests on the flat surface 32 of the upstream part 26 of the nozzle 25, in a region of the base 44 located between the pivot axis of the studs 46 and the branches 45.

The pivoting of the lever 43 thus causes the translational movement along the X axis of the nozzle 25.

The assembly 1 also comprises a container 48, better visible in Figures 4 and 5, comprising a circular bottom 49 and a side wall 50 delimiting an internal volume 51.

The base 49 comprises a self-sealing deformable closure member 53 made of elastomer, offset with respect to the axis of the container. The side wall 50 comprises axial stops formed by ribs 54 extending from the bottom 49 along the axis of the container 48, for example three ribs 54 regularly distributed over the circumference. The ends of the ribs 54 opposite the bottom 49 form axial stops making it possible, in the event of stacking of containers 48, to keep the bottoms 49 of the containers 48 spaced apart from each other. The side wall 50 further comprises an external recessed zone 55, extending parallel to the axis of the container 48 from the bottom 49. The recessed zone 55 has a flared shape in the axial direction, said recessed zone 55 s. 'flaring towards the bottom 49. Said hollow zone 55 forms a projection in the internal volume 51 of the container 48.

The recessed area is diametrically opposed to the closure member 53. The length of the recessed area 55 or projecting is greater than the length of the grooves 54. Thus, when stacking several containers 48, those- these must be aligned and positioned angularly with respect to each other so that the recessed areas 55 fit into each other, so that the bottoms 49 can come to bear on the free ends of the ribs 54.

In order to fill one of the containers 48, a user can grab the container 48 and place the bottom 49 at the level of the central opening 13 of the cover 1 1 by aligning the rib 16 of the cover 1 1 with the recessed area 55 of the container 48. In this angular position of the container 48 relative to the cover 11, the closure member 53 is also aligned with the dispensing part of the nozzle 25. The user can then push the container 48 into the opening 13 so that the dispensing part 37 enters the internal volume 51 of the container 48 through the closure member 53 which deforms to allow such an introduction. It will be noted that the closure member 53 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 51 of the container 48 , the bottom 49 of the container 48 comes into contact with the upper edges 47 of the branches of the lever 43, as illustrated in FIG. 17.

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 make it pivot about its axis 46, as illustrated in Figure 18. This causes a downward translational movement of the nozzle 25, so that the sampling rod 31 presses on the valve of the reservoir 3 and moves it to its open position, against the return force exerted by the corresponding return spring and / or against the force exerted by the gas contained in the reservoir 3.

The liquid contained in the reservoir 3 then rises in the channel of the nozzle 25, under the effect of a pressurized gas contained in the reservoir 3 or delivered by means of appropriate ancillary means, from upstream to the downstream, until opening into the internal volume 51 of the container 48 through the opening 40 of the dispensing part 37. It will be noted that, when the valve is opened, the opening 40 is entirely located in the internal volume 51 of the container 48. 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 illustrated in FIG. 17, causing the valve to close.

The full container 48 can then be removed upwards, the self-sealing element 53 sealing the bottom 49 of the container 48.

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

Figures 19 to 22 illustrate another embodiment, which differs from that explained above in that the nozzle 25 comprises an upstream part 26 and a downstream part 28. The upstream part 26 is fixed, for example by snap-fastening, on the base 19.

The upstream part 26 comprises, as before, a body 29 in which is formed a liquid circulation channel 30. A sampling part 31 in the form of a hollow rod 31 of axis X extends from the body. 29. The channel 30 extends along an axis and is blind at a first end. The channel 30 is closed at a second end by a plug 30a mounted fixedly and in a sealed manner on the body 29.

The channel of the sampling portion 31 opens at a first end at the level of the free end of the hollow rod, and at the other end in the channel 30 of the body 29. The body 29 comprises, as before, a flat surface. 32, facing upwards, extending in the radial plane.

The downstream part 28 comprises a body 36 forming the elongated hollow distribution part 37, with an axis parallel to the X axis. The body 36 has an opening 40 near its free end. The other end of the body 36 is fixed, for example by snap-fastening, on the upstream part 26.

As before, the opening 40 is oriented in a radial plane and along an axis forming an angle with the radial direction, that is to say with the straight line formed in the radial plane and passing through the center of the distribution part. 37 and by the X axis.

The free end 41 of the dispensing portion 37 is hemispherical, frustoconical, or bullet-shaped. The other end of the body 36 opens into the channel 30 of the upstream part 26.

In operation, the liquid passes through the channel 30 of the upstream part 26, then the channel of the dispensing part 37 or of the body 36, before escaping through the opening 30. The general operation of the embodiment of the figures 18 to 22 is similar to that described previously with reference to Figures 1 to 18.

Figures 23 to 27 illustrate a beverage dispensing device 18 according to another embodiment of the invention. This device 18 is in particular intended for use with a non-pressurized tank 3. This device 18 comprises, as previously, a base 19, a nozzle 25 and a lever 43. The same elements as those described above have been designated by the same references in Figures 23 to 27.

The base 19 is mounted on a fixing plate 52 intended to be mounted on the tank 3 or on the tank 2. The plate 52 is formed by a sheet having attachment areas 43 at its ends.

The body 20 of the base 19 comprises an orifice 54 (Figures 25 and 26) located at the level of the median plane of the body 20, said orifice 54 serving for mounting a gas supply line 55 connected to a gas tank under pressure 56 formed here by a commercial cartridge screwed into a connecting member 57 connected to the pipe 55.

The body 20 further comprises a tubular portion 58 extended by a plunger tube 59 intended to be inserted into the reservoir 3. The lower end of the plunger tube 59 comprises one or more openings 60 allowing the suction of the liquid contained in the reservoir 3. A pressurization channel 61 is formed in the tubular part 58 and opens out at one or more orifices 62, said pressurization channel 61 also opening out into the orifice 54. The orifices 62 are intended to be housed in the reservoir 3. , so as to pressurize the internal volume of said tank 3, using the pressurized gas coming from the pressurized gas tank 56.

A sleeve 63 is also mounted in a housing 64 of the tubular part 58, the sampling part 61 being engaged in a sealed manner in the upper end of the sleeve 63. Such a seal is provided by a seal 65, here a seal. toric 65.

A valve 66 is mounted at the lower end of the sleeve 63, this valve 66 being movable between a high closed position of the lower end of the sleeve 63, illustrated in Figures 25 and 26, and a low open position from said end. The valve 66 is kept resting on said end of the sleeve 63, in the closed position of said end, by means of an elastic return member 67, here a helical compression spring 67.

The valve here belongs to the device 18. It is also possible to consider that, given the position of the valve inside the reservoir 3, it belongs to the reservoir. This is only a question of definition, but it does not change the actual structure or the functioning of the whole.

As illustrated in Figure 27, the valve 66 has a lower closure part 66a and an upper guide part 66b. The guide portion 66b is perforated to allow the introduction of fluid from the reservoir 3 and the dip tube 59 into the sleeve 63.

The guide portion 66b comprises for example arms 67, here three arms 67, regularly distributed and angularly spaced from each other. Each arm 67 has a radially outer surface 68 in the form of a cylinder portion, of complementary shape to the surface. internal of the sleeve 63. The arms 67 thus make it possible to guide the valve 66 relative to the lower end of the sleeve 63, so as to allow its opening in operation. Thus, when using such a device 18, the reservoir 3 is pressurized with the aid of the pressurized gas contained in the reservoir 56, through the connection 57, the pipe 55, the orifice 54, the channel 61 and orifice (s) 62.

Furthermore, a user actuates the lever 43 with the aid of a container 48, which has the effect of moving the nozzle 25 downwards, and in particular the sampling part 31, as already described above.

The downward movement of the sampling portion 31 moves the valve 66 towards its open position, against the return force exerted by the elastic return member 67. Liquid from the reservoir 33 then passes through successively the orifices 60, the internal volume of the dip tube 49, the internal volume of the tubular part 58 of the body 20, the spaces formed between the arms 67, the internal volume of the sleeve 63, then the internal channels of the various parts of the nozzle 25 before opening into the container 48 through the orifice 40 of the nozzle 25. When the user removes the container 48, the valve 66 and the nozzle 25 are returned upwards by the elastic return member 67, closing thus the valve 66, which prevents the liquid contained in the pressurized tank 3 from accidentally spilling.
