Description

Technical area

The present invention relates to a cup to be filled with a liquid injected from the bottom of the cup with a filling system. The present invention also relates to a connection device for connecting the cup with a filling system.

State of the art

[0002] In general, the glasses are simple containers presenting no complexity. Their filling is carried out in principle by pouring the liquid from the top of the containers, or through the upper opening of the glass. This pouring from the top of the container is possible through various instruments such as decanters, spouts, faucets and in the presence of soft drinks distributors such as for soft drinks, such as beer, distributors or shooter. beer.

The flow of liquids traditionally from the top of the container generates a slow beverage dispensing rate. In a bar for example, the beverage service requires the intervention of a person whose role will be to manually fill the glasses, and adapt the way to serve each variety of drinks. In addition, the service of specific drinks such as soft drinks, including alcoholic drinks, may take more time than the service of another type of drinks. Indeed, when the filling liquid is gaseous, 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 therefore the generation of a large amount of foam. In order to minimize foaming, the gaseous 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. The flow of the liquid can be carried out in one step but is often carried out in several steps depending on the pouring conditions and the liquid, so as to rest the foam between each pouring step. For example, the draft of a beer typically takes more than one minute requiring the bartender's full-time attention.

The filling of glasses of carbonated beverages such as beer thus has as a major drawback a certain loss of time, justified by the particular care to be devoted to the service of such a drink. Indeed, the filling speed of the glass of a beer for example is limited, which represents a low productivity of 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 printer. Thus and according to this practice, the server is obliged to hold the glass during filling, and can perform other tasks in parallel when the glass fills.

In addition to the adequate time and necessary for the distribution of the soft drink such as beer, the manual service of the soft drink may have other disadvantages. Indeed, the manual dosing of the foam causes a lack of precision in the volume of real beer served to a waste of part of the liquid. In addition, soft drink dispensers such as beer drawers for example that are often exposed on the counter of a bar occupy an important space that it would be particularly preferable to reserve other items.

These disadvantages are a problem in everyday life in all pubs and especially at events such as festivals and other major events, including music or sports.

WO 2009 143 164 proposes a liquid transfer system. This liquid transfer system consists of a fluid reservoir, and a container whose bottom comprises an opening. This liquid transfer system also comprises a coupled device which 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 to seal 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 less than the perimeter of the opening of the container. The passage of the seal at the opening is effected by pressing on the rigid part for sealing. Such a device makes it possible to fill a container at the bottom of its structure and to close it by means of a magnetic element. The magnetic element, however, does not guarantee complete sealing, in particular because it can be shifted slightly randomly

The patent application WO 2011 091 047 provides a liquid distribution assembly consisting of a valve, a container and a connector for circulating the fluid. The valve is composed of a sensor which makes it possible to detect the correct positioning of the container thanks to 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, this element does not guarantee a complete seal.

The two previous documents relate to a beverage dispensing system whose container has an opening at its bottom, which can be plugged by a closure member made of magnetic material. Such an arrangement requires that the magnetic components appear both on the liquid distribution system, on the glass and on the element dedicated to closing the bottom opening. Such an architecture, in addition to being complex, represents a significant cost due to the affixing of various magnetic elements on the entire beverage distribution system. The magnetic solution is expensive and is not suitable for disposable disposable glasses. In addition, the closure of the glass bottom by the magnetic material does not guarantee a completely reliable seal, the closure can be disengaged with a simple movement. Finally, a mixture of materials such as that composing the invention described above poses ecological problems.

WO 2007 141 719 proposes a liquid distribution system. This system includes 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 through the dispensing nozzle which enters the container through an opening and a check valve. The container is thus filled, and the liquid is maintained by sealing the specific opening at the bottom of the container. The system described in this document makes it possible to fill a glass by its bottom, while allowing the liquid to be maintained by means of a bottom-glass valve folded back after dispensing. The valve here in spiral form, is complex to achieve and causes a significant manufacturing cost. In addition the arrangement of the spiral valve does not allow complete hermeticity.

WO 2011 106 259 relates to a liquid distribution system requiring a container whose base comprises an opening. The dispensing system controls the flow of liquid in the tank to allow rapid filling. The container mentioned in this application is a glass whose bottom has an architectural opening here again in spiral form. Thus, although such a system allows to fill a glass by its bottom, its architecture remains complex to manufacture especially in terms of mechanical arrangements required, thereby making the device relatively expensive. The waterproofness of such an architecture is also not guaranteed. Finally, the spiral area of the glass is particularly difficult to clean.

The patent application WO 2007 102 139 relates to a container consisting of a base and at least one wall, and wherein the base and the wall define a space for receiving the drink. The container further includes a resealable opening adjacent to the base for filling the beverage container from below. According to a particular embodiment, the opening is provided in the bottom of the container and a "non-return" valve is deposited in said opening. This "non-return" valve allows the beverage to be dispensed into the container through the glass bottom opening and prevents spillage of the beverage. The glass described here has an opening at its bottom, which allows the pouring of liquid and which is made potentially sealed by a silicone valve system. The hermeticity of such an arrangement is not complete, however, since the silicone valve is the only closure in the glass bottom.

The arrays aroused have the respective disadvantages of being of complex construction and / or not being effectively sealed.

Example (s) of embodiment of the invention

The present invention proposes to produce a low cost cup, consisting of a single material and low ecological footprint, and including a self-sealing valve for filling from below.

FIG. 1 shows a perspective view of a cup 1 according to an embodiment in which the cup 1 comprises a substantially cylindrical wall, or frustoconical, 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 disk 21 and a filling valve 2 arranged to allow a connection of the cup 1 to a bottom beverage filling system. The filling valve 2 is operable in a filling position allowing the introduction of a liquid from the filling system in the filling volume 11 and in a sealed position allowing the storage without leakage of the liquid introduced into the filling volume 11 .

According to an embodiment illustrated in FIGS. 2A and 2B, the wall 10 and the bottom 20 are made of two separate parts. In this case, the wall 10 is also provided with an opening 15 at the base of the cup 1, the side of the bottom 20. During assembly of the bottom 20 with the wall 10, a collar 22 on the periphery of the bottom 20 is pressed against a bottom holding 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 flange 22 of the bottom 20 allows a seal at level of the periphery of the bottom of the cup 1 while being pressed against the retaining wall 14 background. The plating is permitted by the elasticity of the flange 22 and the bottom holding wall 14.

The cup 1 may be made of plastic material (for example polypropylene or any other material suitable for manufacturing by injection) by an injection method. For example, the wall 10 and the bottom 20 may be made by injection separately, but preferably simultaneously, by the injection method. The substantially cylindrical or frustoconical wall 10 and the bottom 20 are placed in the same mold and connected by an injection core. The injection core is split into two pieces at the end of the injection process. The wall 10 and the bottom 20 are then placed against each other either manually or by an assembly machine which pushes a flange 22 of the bottom 20 against a bottom wall 14.

In a variant illustrated in FIGS. 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 molding operation -injection. The hinge 30 is bent or cut during assembly of the flange 22 of the bottom 20 in the wall 14 of the bottom hold.

It is understood that the wall 10 and the bottom 20 may consist of a single piece. For example, the bottom of the cup 20 is a single piece monomaterial made in the extension of the wall 10 of the cup.

Preferably, the wall 10 and the bottom 20 are made with a thin thickness and preferably substantially constant. For example, the thickness of the wall 10 and the bottom 20 may be between 0.1 mm and 1 mm, but is preferably about 0.4 mm. Such a thickness makes it possible to inject the cup 1 at low cost and at a high rate. These two parts can be manufactured in the same mold with several cavities. This approach makes it possible to manufacture all the parts in a single injection, namely the wall substantially 10 and the bottom 20. The design of the cup 1 leads in fact to low production costs and a low ecological footprint.

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

[0040] Referring to FIGS. 1 to 3B, the cup 1 comprises a connecting element 23 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 connecting element 23 in the sealed position and is spaced from the connecting element 23 in the filling position. In the latter position, the liquid can flow to and from the filling volume 11.

In particular, the deformable element 12 comprises a shutter 16, adapted to cooperate with the connecting element 23 and held by a plurality of elastic arms 13. The shutter 16 provides a seal of the central zone of the bottom ( where the filling is carried out) by being pressed onto a sealing ring 24 of the connecting element 23. The plating 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 illustrated example, the arms 13 flex when mounting the body 10 and the bottom 20. The arms 13 generate a constant force between the shutter 16 and the sealing ring 24 in position waterproof. 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 provide the self-sealing function of the valve 2.

Figs. 4A and 4B show a partial view of the cup 1 and a filling system with which it is in cooperation, according to one embodiment. During the filling phase, the cup 1 is placed on the filling system blocking it in translation. In particular, a connection device 40 may be used to functionally connect the cup 1 with the filling system. This connection device 40 has a pouring element, represented by a filling cannula 44 in FIGS. 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 folding the elastic arms 13, thereby creating a gap 31 between the shutter 16 and a sealing ring 24 on the connecting member 23. In the example particular of fig. 2A and 2B, the connecting element 23 is of frustoconical shape and the sealing ring 24 is 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 forms of the shutter 16 are advantageously defined to create no 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 substantially high, even using foamy liquids such as beer. The filling rate is thus substantially higher than when the cup is filled in a conventional manner from above.

In the particular example of FIGS. 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 not towards the filling system). When it is inserted in the connection element 23, the canula 44 can also make it possible to block the cup 1 in translation. However, it is 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 the simple driving of the cannula 44 in the element of connection 23. Still in the particular example of fig. 4A and 4B, the connection device 40 also comprises a holding disk 42 configured to receive the cup 1 and block it in translation. The retaining disc 42 may comprise clipping means 43 so as to provide a rigid attachment of the cup 1 to the retaining disc 42. The cannula 44 housed in the connecting element 23 may also fulfill the role of locking in translation of the cup 1.

At the end of filling, when the liquid pressure is cut, the resilient arms 13 unfold to press sealingly again the shutter 16 against the sealing ring 24. The connecting member 23 is at again sealed, and the liquid remains in the filling volume 11 without leakage to the outside.

The disc 21 bottom and the sealing provided by the flange 22 of the bottom 20 and the filling valve 2 in the sealed position allow the storage without leakage of liquid in the filling volume 11.

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

The principle of the invention is not limited to the embodiment described. Thus figs. 5A to 8 are representations of alternative embodiments of the filling valve 2 for coupling to a beverage dispensing system. The manufacture of the cup 1 can be carried out in a single time and result from the same molding operation. Whichever alternative is taken into consideration, the cup bottom constitutes a watertight valve at rest and allowing the beverage to pass when a filling cannula is inserted into the bottom of the cup.

Figs. 5A and 5B illustrate a first example of an alternative embodiment in which the bottom 20 of the cup 1 comprises a valve 2 consisting of a deformable element 12 that can be deformed between a sealed position (FIG. 5B) and a filling position (FIG. 5A) under the pressure of the liquid. More particularly, a first portion 12 of the deformable element comprises orifices 32 allow the flow of liquid when the deformable element 12 is in the filling position. These orifices 32 are to be blocked by a second portion 12 of the deformable element when the deformable element 12 is folded into the sealed position.

Figs. 6A and 6B are a representation of another alternative embodiment of the cup bottom 1. In this variant, the valve 2 comprises a deformable element 12 spirally between a sealed position (FIG 6B) and a filling position (FIG. 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 spiral. In the sealed position, the turns 12 close tightly by the return constant of the deformable element 12.

FIG. 7 is an illustration of an alternative embodiment in which 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 sealingly.

FIG. 8 is a representation of still another alternative embodiment of the valve 2 comprising a deformable element 12 comprising a valve 12 deformable between a sealed position (solid lines) and a filling position (scored) in which the valve 12 is open creating an orifice 32.

The single injection of polymer resulting in the realization of the cup 1 consisting of a wall 10 and a bottom 20 with the filling valve 2 reduces production costs. In addition, the small thickness of the parts of the cup allows in addition to the economic production, a high-speed manufacturing, the elements being assembled by a machine and then stacked.

Finally, when the deformable element 12 of the valve 2 is in the sealed position, the cup 1 can still be affixed to 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 dedicated dispensing system for this purpose.

The cup filling system 1 described above can be advantageously used in the context of a beverage service, in particular beer or any other beverage or liquid.

The figures and their descriptions made above illustrate the invention rather than limit it.
