[0011] Figure 1 shows a beverage machine 100 according to the invention. The machine comprises a cup holder 6 for placing a drinking cup so that the beverage can be dispensed into the cup from a beverage outlet 7. The beverage is prepared from two brewing units held inside the machine and covered by an external housing.

[0012] In Figure 2 the housing of the machine of Figure 1 has been removed and the two brewing units separated from the rest of the machine.

[0013] The first brewing unit 1 allows to prepare a first beverage from a pack, as described below. Preferably, this first brewing unit is configured to prepare a milk-based beverage, such as milk or foamed milk, or a beverage resulting from the dissolution of a soluble beverage ingredient, such as chocolate or soluble instant coffee.

[0014] The second brewing unit 2 allows for the preparation of a second beverage from a pod, as described below. Preferably, this second brewing unit is configured for the preparation of a coffee-based beverage, in particular from roast and ground coffee.

[0015] Packs and pods are two different containers that contain preportioned beverage ingredients. The ingredients are preportioned as single servings (e.g., enough to produce one serving of beverage). The container may have a maximum capacity to contain only the precursor material for said single serving. The container may be disposable, e.g., physically altered after the preparation process, which may include one or more of: perforation to supply fluid to the beverage ingredients, perforation to supply the beverage from the container, opening by the user to extract the beverage ingredients.

[0016] The two beverages are extracted at the cup holder position. The machine allows the preparation of a final beverage consisting of either the first beverage or the second beverage, or a mixture of the first beverage and the second beverage, such as a cappuccino or a latte macchiato.

[0017] The first brewing unit 1 is provided with an openable door 16 for introducing the puck into the machine.

[0018] The second brewing unit 2 comprises an actuation device 24 which is a handle 241 attached to an interrelated knee lever 242 to allow the movement of the sub-parts of said unit as will be explained below.

[0019] The machine comprises a valve 4 mounted on one part of the machine chassis, here the chassis part 14 of the first brewing unit.

[0020] FIG. 3A is a perspective view of a pack 8 which can be used as a first type of container in the first brewing unit 1.

[0021] The pack contains ingredients configured to be mixed with a fluid to produce a beverage. The pack has a planar shape oriented along a plane P. Two longitudinal planar walls 83 (front and rear) extend along this plane P.

[0022] In this particular embodiment, the walls are made of a flexible material and have sealed side edges 84, as well as a sealed edge at the top end 85. The bottom surface 81 comprises an area 82, which is an openable area. This openable area 82 may be a hole covered by a pierceable cover or membrane. This openable area 82 is adapted to allow the introduction of a fluid treatment device 11 of Figure 3B so that said device protrudes inside the interior volume of the pack in order to introduce the fluid and collect and dispense the beverage.

[0023] Such a pack may correspond to the packs described in WO 2022 / 023578 or WO 2022 / 022901.

[0024] FIG. 3B shows a perspective view and a cross-sectional view of a fluid treatment device 11 of a first extraction unit using the pack 8.

[0025] The body of the device 11 comprises a body 114 which is preferably essentially cylindrical, and an upwardly pointed end 113 which preferably exhibits a conical shape extending from the body 114 .

[0026] This body is an internal inlet conduit 111 for delivering a fluid, preferably water, to a pointed end 113, as indicated by arrow W; an internal outlet conduit 112 for conveying the prepared beverage in a downward direction from the internal volume of the pack, as indicated by arrow B; Equipped with.

[0027] By internal, it is meant that these conduits extend inside the body rather than along the surface of the body, so that when a fluid treatment device is introduced into the pack, liquid flows into and out of the pack through these internal conduits which provide better guidance.

[0028] Both of these conduits are separate from each other. Each conduit 111, corresponding 112, has an end 111a, corresponding 112a, respectively, which emerges at the top of the body.

[0029] Preferably, the end 111a of the inlet conduit is designed to direct a jet of fluid upwards inside the pack.

[0030] The actuation device 12 (Figure 5) is adapted to move this fluid treatment device 11 towards the puck 8 held in the puck chamber 13 (Figure 5) of the first extraction unit, in particular to move the pointed portion 113 towards the openable area 82, in order to open the openable area 82 or a membrane or cover provided in this area. In an alternative embodiment, the actuation device 12 may also be adapted to move the puck 8 towards the fluid treatment device 11 to achieve the same effect.

[0031] FIG. 4A shows a pod 9 used as a second type of container in a second brewing unit of the machine 100.

[0032] The pod 9 comprises a pod body 91 having one side wall 911 extending axially from a bottom wall 912 to the top. Generally, any transverse cross section of the body is circular from bottom to top and the flange is also circular. The body defines a chamber for containing beverage ingredients.

[0033] The beverage raw material is preferably a raw material that can be extracted with water, such as roast and ground coffee. In a preferred method, the beverage raw material may be tea leaves or a water-soluble powder raw material such as instant coffee powder, milk powder, cream powder, instant tea powder, cocoa powder, soup powder, fruit powder or a mixture of the above powders, or a soluble liquid raw material or even a beverage concentrate such as a syrup or a milk concentrate. The powder may be agglomerated or sintered.

[0034] The pod includes a lid 92 that is secured, sealed or otherwise attached to a peripheral flange on the top of the pod body, thus covering and closing the top opening of the body.

[0035] The bottom wall 912 is adapted to be perforated so that liquid can be injected into the pod through the perforated opening.

[0036] The lid 92 is adapted to be opened by relative engagement with a piercing device under the effect of increased liquid pressure inside the pod during injection of liquid.

[0037] The pod shape is symmetrical about a central axial axis ZZ' that extends from the bottom wall to the lid, and the pod shape is asymmetrical about the plane and flange of the lid.

[0038] During extraction, the pod is configured to be enclosed between two pod-enclosing parts of a second extraction device, which comprises an upstream pod-enclosing part and a downstream pod-enclosing part that are relatively movable, preferably translatable, along a longitudinal axis (XX') between an open position for inserting and / or removing the pod and a closed position for forming an extraction chamber that encloses the pod during extraction.

[0039] 4B and 4C are isolated perspective views of two pod-enclosing parts 21, 22 of a second brewing unit using the pod 9. FIG.

[0040] The upstream part 22 defines a cage or cavity for enclosing the pod body. The end wall 221 of the cage carries piercing elements 222 for opening the bottom wall of the pod body and liquid outlet openings 223 for supplying liquid into the pod through holes opened in the bottom wall of the pod. These piercing elements can comprise perforators in the form of blades. These blades can be designed and arranged to pierce the bottom wall of the pod body when the upstream pod enclosing part and the downstream pod enclosing part are in the closed position. The liquid outlet openings 223 can form a shower in front of the end wall of the cage, and the supplied liquid can be introduced into the pod through the pre-pierced openings.

[0041] The downstream part 21 comprises a plate carrying a piercing device 212 for opening the pod lid. Typically this downstream planar piercing device 212 is circular like the pod lid. A beverage outlet 211 is provided for dispensing the beverage.

[0042] The opening occurs by relative engagement of the piercing device with the lid under the effect of the increased pressure of the liquid injected in the pod body chamber. This downstream piercing device may comprise a rigid plate provided with opening elements such as spikes, which may have the shape of a cone or pyramid, optionally with a truncated end, on its surface facing the lid. In addition, the plate comprises transverse holes for draining the dispensed beverage from the opened lid to a beverage outlet 211, such as a tube or nozzle, which collects the beverage and dispenses it into a drinking cup.

[0043] Figures 4D and 4E are side views of the two enclosing parts 21, 22 showing their relative movement between an open position (Figure 4D) for inserting and removing the pods and a closed position (Figure 4E) for forming a brewing chamber that encloses the pods during brewing. The enclosing parts 21, 22 are relatively translatable along a longitudinal axis XX'. Normally, this axis XX' is essentially horizontal inside the machine 100. In Figure 4E, the two parts are in a closed position configured to brew the pods. The two enclosing parts 21, 22 are supported by the chassis 25 of the second brewing unit and are movable between the two positions by actuating a handle 241 connected to them by a system 242 of interrelated knee levers. This second brewing unit is therefore manually operated.

[0044] As shown in FIG. 4E, this second brewing unit 2 comprises a pod holder 23 for receiving and holding a pod 9 between two enclosing parts.

[0045] FIG. 5 corresponds to FIG. 2, in which the core part of the brewing unit is separated and the fluid supply system 3 is shown diagrammatically.

[0046] This fluid system 3 normally comprises a tank 31 of fluid, typically water, a pump 33 for pumping said fluid from the tank, and at least one device for adapting the temperature of the fluid, such as a heater 32 and / or a cooler, before it is supplied to the brewing unit via the valve 4. The heater 32 is connected by a fluid supply pipe 43 to a fluid inlet 421 of the valve. The valve comprises two fluid outlets, which are: It is adapted to dispense fluid into the first extraction unit 1 by connecting its first outlet 422a to the fluid supply pipe 15 of said first unit, the other end of which is connected to a fluid treatment device.

[0047] or, The second outlet 422b is connected to the fluid supply pipe 26 of the second unit, thereby dispensing fluid from the second brewing unit 2. The other end of the fluid supply pipe 26 is connected to the fluid inlet 221 of the upstream surrounding portion.

[0048] The process control unit 5 of the beverage machine is configured to control the pump 33, the heater 32 and optionally the motor 121 of the first brewing unit when a beverage is ordered.

[0049] This unit 5 can be used to control the recognition device 7 or other controllable devices such as a display, if present.

[0050] In Figure 5, the door 16 and housing of the first brewing unit have been removed to reveal the puck chamber 13 configured to receive and hold the puck 8 during beverage preparation, and its puck inlet 132 through which the puck is introduced. The puck chamber has a bottom opening 131 configured to allow interaction between the fluid treatment device 11 and the openable area 82 of the puck. This unit 1 comprises an actuation device 12 configured to move the treatment device 11 relative to the puck 8 in order to pierce the openable area and prepare the beverage. In this illustrated embodiment, this actuation device comprises a motor 121 configured to rotate an interconnected gear 122 that is coupled to the treatment device 11.

[0051] This first extraction unit 1 may be similar to the units described in WO 2021 / 110654, WO 2021 / 110650 and / or WO 2021 / 110652.

[0052] Figures 6A and 6B are respectively a perspective view and a cross-sectional view of the valve 4 of the machine of Figure 5. This valve 4 comprises two tubes 41, 42, one disposed inside and slidable inside the other.

[0053] The external distribution pipe 42 has a fluid inlet 421, a first outlet 422a connectable to the first unit 1 via pipe 15, and a second outlet 422b connectable to the second unit 2 via pipe 26.

[0054] The internal connecting pipe 41 has a fluid inlet 411 and a fluid outlet 412. The internal connecting pipe 41 is disposed inside the external distribution pipe 42 such that the fluid inlets 411, 421 are spaced apart. The fluid inlets of the distribution pipes surround the fluid inlets of the inlet pipes.

[0055] In this illustrated embodiment, the outer tube 42 is fixedly attached by its end 423 to the frame of the second extraction unit.

[0056] The internal connecting pipe 41 slides inside the external distribution pipe 42 and can be positioned in at least two different positions: one first position, in which the fluid outlet 412 of the internal connecting pipe 41 is connected with a first outlet 422a of the external dispensing pipe, so that fluid can be supplied to the first brewing unit 1 for preparing a beverage from the pack 8; one second position, in which the fluid outlet 412 of the internal connecting conduit 41 is connected with the second outlet 422b of the external dispensing conduit, so that fluid can be supplied to the second brewing unit 2 for preparing a beverage from the pod 9; can be stopped at.

[0057] The movable tube of the valve is indirectly actuated by a motor 121 of the first brewing unit when said motor moves the fluid treatment device 11 to prepare a beverage from the packs 8. As shown in Figure 6C, one free end 123 of the internal connecting tube is attached by a connecting rod 123 to one gear 122 which is rotated by the motor 121, thereby causing a translation of the inner movable tube of the external dispensing pipe when the motor actuates the gear 122 to move the fluid treatment device 11.

[0058] The position of the internal connecting pipe 41 is predetermined as follows.

[0059] By default, the internal connecting pipe 41 is in the second position, allowing fluid to be dispensed from the fluid supply system 3 to the second brewing unit 2 .

[0060] When a beverage is prepared from a pack 8 in the first brewing unit 1, the internal connecting tube 41 is moved to the first position when the fluid treatment device 11 is introduced into the pack. The process control unit 5 can then operate the pump 32 to dispense fluid into the pack.

[0061] Thus, the valve is oriented within the machine and the first outlet 422a and second outlet 422b of the external distribution pipe are positioned within the valve so that the movement of the motor and gears enabling the movement of the fluid processing device 11 is configured to simultaneously displace the fluid outlet 412 of the internal connecting pipe from the second outlet 422b to the first outlet 422a of the external distribution pipe.

[0062] Preferably, the clave 4 is provided with seals 44 for tightness and with inserts 45 for holding these seals in place.

[0063] 7A and 7B show a perspective view and a cross-sectional view of an alternative valve 4. In this alternative, the inner connecting pipe 41 is fixed and its end 413 is attached to the chassis of the first brewing unit, and the outer dispensing pipe 42 is slidable around the inner pipe and its end 423 is attached to the gear by a connecting rod.

[0064] In this application: The term "pod" is used broadly to refer to any type of single-dose container suitable for preparing a beverage or other edible product, such as a capsule, cartridge, portioned package or individual package, without limitation to the shape of the container, the material from which the container is made, or the type of piercing means required to extract the beverage therefrom.

[0065] The term "longitudinally" refers to the orientation of the two enveloping parts relative to each other and their movement along the longitudinal axis XX'.

[0066] The terms "upstream" and "downstream" refer to the path of liquid through the extraction device from an upstream enclosure to a downstream enclosure.

[0067] Generally, these terms are used to describe the relative placement of features of a brewing device and should be understood to refer to the normal orientation of said device when placed in a beverage preparation machine for producing a beverage, as shown in Figures 1, 2 and 5.

[0068] While the invention has been described with reference to the above illustrated embodiments, it will be understood that the invention as claimed is in no way limited to those illustrated embodiments.

[0069] Variations and modifications can be made without departing from the scope of the invention as defined in the claims. Furthermore, where known equivalents exist to specific features, such equivalents are incorporated as if specifically referred to herein.

[0070] As used herein, the terms "comprises," "comprising," and similar terms should not be construed in an exclusive or exhaustive sense. In other words, they are intended to mean "including, but not limited to." [Explanation of symbols]
