Description

Technical field

[0001] The present invention relates to a cup intended to be filled with a liquid injected from the bottom of the cup using a filling system. The present invention also relates to a connection device intended to connect the cup with a filling system. State of the art

[0002] Generally speaking, glasses are simple containers that do not present any complexity. Their filling is carried out in principle by pouring the liquid from the top of the container, that is, through the upper opening of the glass. This pouring from the top of the container is possible thanks to different instruments such as carafes, pouring spouts, taps and in the presence of carbonated drinks, dispensers such as for carbonated drinks, such as beer, dispensers or beer taps.

[0003] The flow of liquids traditionally from the top of the container results in a slow beverage dispensing rate. In a bar, for example, serving drinks requires the intervention of a person whose role will be to manually fill glasses and adapt the serving method to each type of drink. In addition, serving specific drinks such as carbonated drinks, particularly alcoholic drinks, can take longer than serving other types of drinks. Indeed, when the filling liquid is carbonated, for example in the case of beer or soda, the flow of liquid from the top to the bottom of the glass causes turbulence and consequently the generation of a large amount of foam. In order to minimize foaming, the carbonated filling liquid is generally poured at a low flow rate and preferably by tilting the glass so that the liquid follows the wall of the glass.Pouring the liquid can be done in one step but is often done in several steps depending on the pouring conditions and the liquid, so as to allow the foam to settle between each pouring step. For example, pouring a beer typically takes more than a minute, requiring the full attention of the bartender.

[0004] Filling glasses with carbonated drinks such as beer therefore has the major disadvantage of being a certain loss of time, justified by the particular care that must be taken in serving such a drink. Indeed, the speed of filling a glass of beer, for example, is limited, which represents low productivity for the bartender, and therefore a very high production cost per drink. The bartender will only be able to fill one glass at a time using a beer tap. Thus, and according to this practice, the server is obliged to hold the glass while filling, and cannot perform other tasks in parallel while the glass is filling.

[0005] Besides the adequate and necessary time for dispensing a carbonated beverage like beer, manual serving of carbonated beverages can have other disadvantages. Indeed, manual dosing of foam leads to a lack of precision in the actual volume of beer served, leading to a waste of some of the liquid. In addition, carbonated beverage dispensers like beer taps, for example, which are often displayed on a bar counter, take up a significant amount of space that would be preferable to reserve for other elements.

[0006] These drawbacks pose a daily problem in all drinking establishments and particularly during events such as festivals and other large events, particularly musical or sporting ones.

[0007] Document WO2009143164 proposes a liquid transfer system. This liquid transfer system consists of a fluid reservoir and a container whose bottom includes an opening. This liquid transfer system also includes a coupled device that is attached to the opening of the container, and also a glass filling device. The device coupled to the glass is a magnetic material. When in the closed position, this magnetic material serves as a seal for the container containing the fluids, thanks to a magnetic attraction with the bottom of the glass. The glass filling device comprises a rigid member whose perimeter is smaller than the perimeter of the container opening. The transition from tight closure to opening is carried out by pressing on the rigid part allowing tight closure. Such a device makes it possible to fill a container from the bottom of its structure and to close it thanks to a magnetic element.However, the magnetic element does not guarantee total sealing, particularly because it can be slightly offset at random.

[0008] Patent application WO2011091047 provides a liquid dispensing assembly consisting of a valve, a container, and a connector for circulating the fluid. The valve is composed of a sensor that detects the correct positioning of the container using a magnetic material placed at the bottom of the container. Such a beverage dispensing system requires a magnetic element to close the bottom of the glass; however, this element does not guarantee a complete seal.

[0009] The two preceding documents concern a beverage dispensing system whose container has an opening at its bottom, which can be closed by a closing element made of magnetic material. Such an arrangement requires that the magnetic components appear on the liquid dispensing system, as well as on the glass and on the element intended to close the opening at the bottom. Such an architecture, in addition to being complex, represents a significant cost due to the affixing of various magnetic elements on the entire beverage dispensing system. The magnetic solution is expensive and is not suitable for single-use disposable glasses. In addition, the closing of the glass bottom by the magnetic material does not guarantee a fully reliable seal, as the closure can be disengaged with a simple movement.Finally, a mixture of materials such as that making up the invention described above poses ecological problems.

[0010] Document WO2007141719 proposes a liquid dispensing system. This system comprises liquid dispensing spouts that can be connected to containers. These containers respectively have valves inclined towards the same direction. A container can thus be positioned on the device thanks to the dispensing spout which penetrates into the container, via an opening and a "non-return" valve. The container is thus filled, and the liquid is maintained thanks to the tightness of the specific opening at the bottom of the container. The system described in this document makes it possible to fill a glass from its bottom, while allowing the liquid to be maintained thanks to a valve at the bottom of the glass folded down after dispensing. The valve here in the form of a spiral, is complex to produce and results in a significant manufacturing cost. In addition, the arrangement of the spiral valve does not allow for complete airtightness.

[0011] Document WO2011106259 relates to a liquid dispensing system requiring a container whose base includes an opening. The dispensing system controls the flow of liquid into the tank to allow rapid filling. The container referred to in this application is a glass whose bottom has an opening, again designed in the form of a spiral. Thus, although such a system allows a glass to be filled from its base, its architecture remains complex to manufacture, particularly in terms of the required mechanical arrangements, thus making the device relatively expensive. The sealing of such an architecture is also not guaranteed. Finally, the spiral-shaped area of ​​the glass is particularly difficult to clean.

[0012] Patent application WO2007102139 relates to a container consisting of a base and at least one wall, and in which the base and the wall define a space for receiving the beverage. The container further comprises a closable opening, adjacent to the base, allowing the container to be filled with beverages from below. According to a particular embodiment, the opening is provided in the bottom of the container and a "non-return" valve is placed in said opening. This "non-return" valve allows the beverage to be dispensed into the container through the opening at the bottom of the glass, and prevents the beverage from spilling. The glass described here has an opening at its bottom, which allows the pouring of liquid and which is potentially made watertight by a silicone valve system. The airtightness of such an arrangement is however not total since the silicone valve represents the only closure at the bottom of the glass.

[0013] US2008223478 discloses an apparatus for filling specially designed beverage containers from the bottom via a one-way orifice. One embodiment of the invention utilizes an umbrella valve mounted in a perforated cap, which is interference-fitted into the bottom of a beverage container. When engaged with concentric O-rings on a fluid dispensing assembly, a vacuum suction secures the beverage container to the fluid dispensing assembly, creating a sealed channel for the fluids to pass through. The fluids originate from a pressurized reservoir and are fed through a fluid supply, forcing the umbrella valve open and allowing fluid flow into the interior volume of the beverage container. Once filling is complete, the reservoir is depressurized, allowing the umbrella valve to snap closed.

[0014] The above arrangements have the respective disadvantages of being of complex construction and / or of not being effectively waterproof. Brief summary of the invention

[0015] To overcome these various drawbacks, the invention provides various technical means.

[0016] Another object of the invention is to provide a cup which can be filled in a single injection.

[0017] Yet another object of the invention provides a system for dispensing beverages, in particular beer, but also any other beverages, allowing several cups to be filled simultaneously.

[0018] Another object of the invention relates to a cup which can be manufactured easily and inexpensively.

[0019] Yet another object of the invention provides a single-use cup with low ecological impact.

[0020] Another object of the invention makes it possible to produce a cup from a single material.

[0021] To this end, the invention provides a cup comprising a wall delimiting a filling volume arranged between, on a first side, a bottom, and on the opposite side, an opening; a filling valve provided in the bottom and operable between a filling position, allowing the introduction of the liquid into the filling volume when the cup cooperates with the filling system, and a sealed position allowing the storage without leakage of the liquid introduced into the filling volume; said valve comprising a deformable element mounted in compression in the sealed position and capable of being deformed into the filling position when the pressure of the injected liquid is greater than a predetermined compression value of the deformable element; said valve comprises a connection element allowing the passage of the liquid coming from the filling system into the filling volume;the deformable element being arranged to bear against a sealing ring of the connection element, in the sealed position of the valve, and spaced from the sealing ring in the filling position of the valve; the deformable element comprising a shutter cooperating with the connection element and held by a plurality of elastic arms fixed to the wall and working in flexion and / or compression between the wall and the shutter.;

[0022] In one embodiment, said valve comprises a connection element capable of cooperating with the deformable element so that the deformable element bears against the connection element in the sealed position, and spaced from the connection element in the filling position. The connection element may have a substantially cylindrical or frustoconical shape and comprise a sealing ring; the deformable element bears against the sealing ring in the sealed position, and is spaced from the sealing ring in the filling position.

[0023] The invention also provides a connection device intended to connect the cup with a filling system, comprising a filling cannula connectable to the filling system and capable of cooperating with the valve so as to inject the liquid coming from the filling system into the filling volume when the pressure of the injected liquid is greater than a predetermined compression value of the deformable element.

[0024] Thanks to such an architecture, the valve opens under the pressure generated by the injection of liquid and closes when the pressure reaches a minimum pressure threshold. Filling from the bottom makes it possible to minimize turbulence and foam formation when a foamy liquid such as beer is injected into the cup. The cup of the invention can be advantageously used for carbonated and foamy drinks and also for all kinds of drinks, even non-carbonated or liquid.

[0025] According to an advantageous embodiment, the cup contains a movable shutter cooperating with the connection element and held by a plurality of elastic arms fixed to the wall and working in flexion and / or compression between the wall and the shutter, so that the shutter is held under stress in a closed sealed position by the elastic arms and is moved, under the pressure of the injected liquid, into a filling position in which the shutter releases the connection element by creating a gap between the connection element and the shutter.

[0026] Advantageously, the cup consists of a substantially cylindrical, or truncated, wall and a base, which form a single-material element.

[0027] Also advantageously, the cup is made of a bio-sourced, easily recyclable material such as polypropylene or polylactic acid.

[0028] According to an advantageous embodiment, the cup centering and filling cone is adaptable to a cup filling system from the bottom.

[0029] According to another advantageous embodiment, the cup is obtained by injection molding of a single piece.

[0030] Advantageously, the cup is obtained by injection molding two pieces produced in a single mold and connected by an injection tunnel.

[0031] The invention also relates to the use of the cup in cooperation with the connection device for filling and serving beverages, in particular beer or any other beverages or liquids. Brief description of the figures

[0033] The present invention proposes to produce a low-cost cup, made of a unique material and with a low ecological footprint, and including a self-sealing valve allowing filling from below.

[0034] There figure 1 shows a perspective view of a cup 1 according to an embodiment in which the cup 1 comprises a substantially cylindrical, or frustoconical, wall 10 delimiting a filling volume 11 between, on one side, an opening 30, and on the other side, a bottom 20. The bottom 20 is provided with a bottom disc 21 and a filling valve 2 arranged to allow connection of the cup 1 to a beverage filling system via the bottom. The filling valve 2 is operable in a filling position allowing the introduction of a liquid from the filling system into the filling volume 11 and in a sealed position allowing the storage without leakage of the liquid introduced into the filling volume 11.

[0035] According to an embodiment illustrated in the Figures 2A and 2B, the wall 10 and the bottom 20 are made up of two separate pieces. In this case, the wall 10 is also provided with an opening 15 at the base of the cup 1, on the side of the bottom 20. When assembling the bottom 20 with the wall 10, a collar 22 on the periphery of the bottom 20 comes to bear against a bottom retaining wall 14 on the lower periphery of the wall 10. After assembly, the bottom disc 21 obstructs the opening 15 at the base of the cup and the collar 22 of the bottom 20 provides a seal at the periphery of the bottom of the cup 1 by being pressed against the bottom retaining wall 14. The pressing is allowed by the elasticity of the collar 22 and the bottom retaining wall 14.

[0036] The cup 1 may be manufactured from a plastic material (e.g., polypropylene or any other material suitable for injection molding) by an injection molding process. For example, the wall 10 and the bottom 20 may be injection molded separately, but preferably simultaneously, by the injection molding process. The substantially cylindrical, or frustoconical, wall 10 and the bottom 20 are placed in the same mold and connected by an injection sprue. The injection sprue is separated into two pieces at the end of the injection molding process. The wall 10 and the bottom 20 are then placed against each other either manually or by an assembly machine that pushes a flange 22 of the bottom 20 against a bottom wall 14.

[0037] In a variant illustrated in the Figures 3A and 3B, the wall 10 and the bottom 20 are connected by a hinge 30. In an injection process, the wall 10 and the bottom 20 connected by the hinge 30 can be injected during a single injection molding operation. The hinge 30 is folded or cut during the assembly of the collar 22 of the bottom 20 in the bottom retaining wall 14.

[0038] It is understood that the wall 10 and the bottom 20 may be made of a single piece. For example, the bottom of the cup 20 constitutes a single piece of monomaterial produced in the extension of the wall 10 of the cup.

[0039] Preferably, the wall 10 and the bottom 20 are manufactured with a thin and preferably essentially constant thickness. For example, the thickness of the wall 10 and the bottom 20 can be between 0.1 mm and 1 mm, but is preferably approximately 0.4 mm. Such a thickness makes it possible to inject the cup 1 at low cost and at high speed. These two parts can be manufactured in the same mold comprising several cavities. This approach makes it possible to manufacture all of the parts in a single injection, i.e. the substantially wall 10 and the bottom 20. The design of the cup 1 therefore results in low production costs and a low ecological footprint.

[0040] In one embodiment, the filling valve 2 is provided with a deformable element 12, 13 mounted in compression in the sealed position and capable of being deformed in the filling position when the pressure of the injected liquid is greater than a predetermined compression value of the deformable element. The filling valve 2 therefore has a self-sealing function when the valve 2 is in the sealed position, that is to say, is not stressed by the injected liquid.

[0041] In reference to the Figures 1 to 3B, the cup 1 comprises a connection element 23 intended for connecting the cup 1 to the beverage filling system and for injecting the liquid coming from the filling system into the filling volume 11. The connection element 23 is arranged to cooperate with the deformable element 12, 13 so that the latter bears against the connection element 23 in the sealed position and is spaced from the connection element 23 in the filling position. In this latter position, the liquid can flow into and out of the filling volume 11.

[0042] In particular, the deformable element 12 comprises a shutter 16, capable of cooperating with the connection element 23 and held by a plurality of elastic arms 13. The shutter 16 provides sealing of the central area of ​​the bottom (where the filling is carried out) by being pressed against a sealing ring 24 of the connection element 23. The pressing is done by the elasticity of the elastic arms 13 fixed to the wall 10 and working in flexion / compression between the wall 10 and the shutter 16. In the example illustrated, the arms 13 flex during the assembly of the body 10 and the bottom 20. The arms 13 generate a constant force between the shutter 16 and the sealing ring 24 in the sealed position of the valve 2. This constant force blocks the passage of the liquid between the filling volume 11 and the connection element 23. In this configuration, the arms 13 ensure the self-sealing function of valve 2.

[0043] THE Figures 4A and 4Bshow a partial view of the cup 1 and of a filling system with which it cooperates, according to one embodiment. In the filling phase, the cup 1 is arranged on the filling system blocking it in translation. In particular, a connection device 40 can be used to functionally connect the cup 1 with the filling system. This connection device 40 has a pouring element, represented by a filling nozzle 44 on the Figures 4A and 4B, which is housed in the connection element 23. The filling cannula 44 is connectable to the filling system so as to inject the liquid coming from the filling system into the connection element 23. When the liquid arrives under pressure in the cannula 44, it pushes the shutter 16 by bending the elastic arms 13, thus creating a gap 31 between the shutter 16 and a sealing ring 24 on the connection element 23. In the particular example of Figures 2A and 2B, the connecting element 23 is of truncated cone shape and the sealing ring 24 is located on the periphery of the truncated upper part of the cone. The liquid flows through the gap 31 and fills the filling volume 11 from below. The shapes of the shutter 16 are advantageously defined so as not to create any turbulence, or at least to minimize turbulence, during the flow of liquid, and thus prevent it from foaming. The liquid flow rate can therefore be significantly high, even when using foamy liquids such as beer. The filling rate is thus significantly higher than when the cup is filled conventionally from above.

[0044] The connecting element 23 may also be cylindrical in shape or any other shape allowing the passage of the liquid coming from the filling system into the filling volume 11. For example, the connecting element 23 may be of a section other than circular. The connecting element 23 may have a constant or variable lateral dimension (diameter). The sealing ring 24 is located on the periphery, or circumference, of the end of the connecting element 23 which opens on the side of the opening 30, so as to cooperate with the deformable element 12.

[0045] The shutter 16 may comprise a disc-shaped plate (as illustrated in figure 1). The shutter 16 may also take any other form capable of coming to bear against the sealing ring 24 and obstructing the connection element 23 when the deformable element 12 is in the sealed position and of being spaced from the sealing ring 24 in the filling position of the valve 2.

[0046] In the particular example of Figures 4A and 4B, the cannula 44 comprises a seal 41 allowing the liquid injected by the connection element 23 to flow only on the side of the gap 31 (on the side of the truncated upper part of the cone and not in the direction of the filling system). When it is inserted into the connection element 23, the cannula 44 can also make it possible to block the cup 1 in translation. It is however possible to envisage that the cannula 44 does not comprise a seal and that the seal between the cannula 44 and the connection element 23 is ensured by simply driving the cannula 44 into the connection element 23. Still in the particular example of Figures 4A and 4B, the connection device 40 also comprises a holding disc 42 configured to receive the cup 1 and block it in translation. The holding disc 42 may comprise clipping means 43 so as to be able to rigidly fix the cup 1 on the holding disc 42. The cannula 44 housed in the connection element 23 may also fulfill the role of blocking the cup 1 in translation.

[0047] At the end of filling, when the liquid pressure is cut off, the elastic arms 13 unfold to once again press the shutter 16 against the sealing ring 24 in a sealed manner. The connection element 23 is once again covered in a sealed manner, and the liquid remains in the filling volume 11 without any leakage to the outside.

[0048] The bottom disc 21 as well as the sealing ensured by the collar 22 of the bottom 20 and the filling valve 2 in the sealed position allow storage without leakage of liquid in the filling volume 11.

[0049] The cup 1 of the invention can therefore be made from a single material and has a self-sealing valve. The cup can be manufactured by injection at low cost and at high speed. The cup can be used for single use and is recyclable without disassembly.

[0050] THE Figures 5A to 8are representations not forming part of the invention, of the filling valve 2 allowing coupling to a beverage dispensing system. The manufacture of the cup 1 can be carried out in a single step and result from the same molding operation. Whatever the variant taken into consideration, the cup base 20 constitutes a valve that is sealed at rest and allows the beverage to pass through when a filling nozzle is inserted into the cup base 20.

[0051] THE Figures 5A and 5B show a cup 1 whose bottom includes a valve 2 consisting of a deformable element 12 which can be deformed between a sealed position ( Figure 5B ) and a fill position ( Figure 5A) under the pressure of the liquid. More particularly, a first portion 12' of the deformable element comprises orifices 32 allowing the liquid to flow when the deformable element 12 is in the filling position. These orifices 32 are blocked by a second portion 12" of the deformable element when the deformable element 12 is folded into the sealed position.

[0052] THE Figures 6A and 6B are the representation of another variant of the bottom 20 of cup 1. In this variant, the valve 2 comprises a deformable element 12 in a spiral between a sealed position ( Figure 6B ) and a fill position ( Figure 6A). Here, the deformable element 12 functions as a tension spring. In the filling position, the deformable element 12 is stretched and the liquid can flow between the turns 12' of the deformable element 12 in a spiral. In the sealed position, the turns 12' close tightly by the spring constant of the deformable element 12.

[0053] There figure 7 shows the cup valve 2 comprises a deformable element consisting of a plurality of elastically deformable teeth 12. In the filling position, the teeth 12 deform under the pressure of the liquid so as to create an orifice 32. In the sealed position, the teeth 12 fold back closing the orifice 32 in a sealed manner.

[0054] The figure shows another variant of the valve 2 comprising a deformable element 12 comprising a flap 12' deformable between a sealed position (solid lines) and a filling position (dotted lines) in which the flap 12' is open creating an orifice 32.

[0055] The single injection of polymer resulting in the production of the cup 1 consisting of a wall 10 and a base 20 comprising the filling valve 2 makes it possible to reduce production costs. In addition, the low thickness of the parts of the cup allows, in addition to economical production, high-speed manufacturing, the elements being assembled by a machine and then stacked.

[0056] Finally, when the deformable element 12 of the valve 2 is in the sealed position, the cup 1 can still be placed on the beverage dispensing system. Such an architecture has the effect of allowing rapid filling of the cup and immediate service. The service is thus multiplied by the number of cups 1 that can be filled simultaneously by the dispensing system dedicated to this purpose.

[0057] The cup filling system 1 previously described can be advantageously used in the context of a beverage service, in particular beers or any other beverages or liquids.
