Description

Technical Field

[0001] The present invention relates to a beverage preparation machine, in particular a machine for preparing a beverage product by mixing a fluid substance with ingredients contained in a container, such as a sachet. Background Art

[0002] All known systems for preparing beverages at home involve a machine that receives an ingredient storage container for storing ingredients for preparing a beverage product. Typically, the ingredient container is introduced into the beverage preparation machine, and the machine passes a fluid (usually hot water) through a dosed amount of the ingredient. The beverage product, prepared by mixing the soluble ingredient and the fluid substance, is then dispensed from the container into a consumer container (usually a cup).

[0003] Typically, the fluid transferred from the beverage preparation machine to the container is introduced through a shower plate that contacts the fluid-permeable side of the container. Alternatively, the beverage preparation machine includes a fluid handling device that pierces the inlet wall of the container and injects the fluid therein (usually under pressure). In such beverage preparation machines known in the art, dispensing of the beverage product from the container is performed by:

[0004] a) fluid pressure is built up inside the closed cavity of the container until the dispensing wall of the container opens on its own and allows the beverage product to flow out, or

[0005] b) Piercing the dispensing wall of the container by means of a dispensing needle member (or other similar piercing member) of the beverage preparation machine, which is capable of removing or dispensing the beverage product from the vicinity of the container.

[0006] In the event that the dispensing side of the container opens on its own, this may result in variations in pressure or opening pattern from one container to another and some undesirable variations in the quality of the dispensed beverage product.

[0007] In case the beverage preparation machine comprises a dispensing needle member for piercing the dispensing wall of the container, the technique of adding this dispensing needle member in addition to the fluid handling device for injecting the mixed fluid into the container increases the complexity and cost of the beverage preparation machine.

[0008] Therefore, there is a need for a beverage preparation machine which eliminates the above-mentioned disadvantages of existing beverage systems and which in particular is simpler and provides a more reproducible quality from one beverage product to another over time. Summary of the Invention

[0023] Advantageously, the fluid treatment device further comprises at least one air or gas inlet aperture in fluid communication with the inlet member. The movement mechanism is thus configured for moving the fluid treatment device and the container apart from each other in at least one of the following positions:

[0024] - a first intermediate position, in which the air or gas inlet opening is located outside the interior volume of the container and the sealing member is not engaged with the container, and

[0025] - a second intermediate position, in which the air or gas inlet aperture is located within the interior volume of the container and the sealing member remains disengaged from the container. According to a preferred embodiment, the beverage preparation machine comprises a first locking mechanism for selectively locking / unlocking the container relative to the container holder when the container is received in the container holder, which is fixed relative to the fluid handling device. The movement mechanism comprises a first actuating member for moving the fluid handling device relative to the container between at least a fluid introduction position and a beverage dispensing position, or vice versa. Preferably, the first locking mechanism comprises a first gear and / or lever mechanism that is movable relative to a fixed part of the beverage preparation machine and is provided with at least one tooth that is selectively engageable with at least one corresponding hole provided in the container, wherein in each non-engaged position of the tooth relative to the corresponding hole, the container can be separated from the container holder and, therefore, from the beverage preparation machine. It is always preferred that the first actuating member comprises a second gear and / or lever mechanism connected to the fluid handling device, wherein the second gear and / or lever mechanism is configured to move the fluid handling device relative to the container along a vertical axis.

[0026] According to another preferred embodiment, the movement mechanism comprises a second actuating member for moving the container relative to the fluid handling device between the fluid introduction position and the beverage dispensing position, or vice versa, while the fluid handling device is fixed relative to the container holder. Preferably, the second actuating member comprises a container support device and a third gear and / or lever mechanism. The container support device is actuated by the third gear and / or lever mechanism for moving the container relative to the container holder and relative to the fluid handling device along the vertical axis. It is always preferred that the container support device is provided with a second locking mechanism, which second locking mechanism comprises at least one pin that can selectively engage with at least one corresponding hole provided in the container, wherein in each non-engaged position of the pin relative to the corresponding hole, the container can be separated from the container holder and thus from the beverage preparation machine.

[0027] According to a preferred aspect of the present invention, the container is made of a flexible material and is provided with an additional layer of substantially rigid material at the portion of the container engaged by the fluid treatment device.

[0049] Figure 1 The layout of a beverage preparation machine according to an embodiment of the invention is schematically shown.

[0050] The beverage preparation machine is generally designated by the reference numeral 1 and comprises a fluid circulation system for a fluid substance. The fluid substance is typically water, in a cold state (between 4° C. and 20° C.), an ambient state (between 20° C. and 35° C.), or a hot state (between 35° C. and 95° C.). Preferably, the fluid substance is water at a temperature between 40° C. and 90° C.

[0051] For example, the fluid circulation system preferably includes at least one fluid source 2, at least one fluid pump 3, and at least one fluid circulation conduit 6. The fluid circulation system may also include at least one fluid heating element 4. Such fluid circulation systems are known in the art. The fluid source 2 may be, for example, a removable water reservoir connected to the fluid circulation system. Alternative fluid sources include, for example, a tap water connection, a can of non-aqueous edible fluid, or a water bottle connection. The fluid pump 3 may be, for example, a standard piston pump that delivers a maximum output pressure of 20 bar. Obviously, alternative fluid pumps may be provided.

[0052] The beverage preparation machine 1 comprises at least one container holder 7 adapted to receive a corresponding container C. The container holder 7 is a mechanical element adapted to ensure that the container C is stationarily positioned within the beverage preparation machine 1 (at least during the time when the machine is actually used to prepare beverages), so that a corresponding fluid circulation system can be connected in a functional manner to the container C for injecting a fluid substance into or through the container C. Such container holders are known in the art.

[0053] The beverage preparation machine 1 further comprises at least one fluid handling device 10 which is part of a fluid circulation system and comprises a fluid handling body 12 ( Figure 2 ). The fluid handling body 12 further includes at least one inlet member 18 for introducing a fluid substance into the container C for preparing a beverage product. Preferably, the fluid handling body 12 is a needle-shaped fluid handling body 12. By the term "needle-shaped", the fluid handling body 12 should be intended to include at least one end portion 26, 28, which is configured to penetrate and / or pierce and / or tear a specific portion or wall of the container C before introducing the fluid substance into the container C. The fluid handling body 12 is shaped in a manner capable of at least partially penetrating the container C.

[0054] The beverage product is prepared by mixing a fluid substance with ingredients contained in a container C. Preferably, the ingredients are selected from the following list: roasted and ground coffee, compacted or non-compacted coffee, soluble powdered coffee, or leaf tea. Dairy ingredients (e.g., milk or creamer) may also be provided, as well as chocolate, fruit juice, soup, vegetable juice, broth, smoothies, purees, sauces, cream, or combinations thereof, in powdered soluble form, in liquid concentrates of various viscosities, or in the form of a gel. By the expression "mixing a fluid substance with ingredients," it is intended that all ingredients contained in the container C are in a form compatible with the usual mixing operations (dissolution, extraction, or infusion) of a fluid substance (typically water) to obtain the beverage product.

[0055] According to the present invention, the needle-shaped fluid handling body 12 of the fluid handling device 10 comprises at least one outlet member 20 for dispensing a beverage product from a container C. The beverage preparation machine 1 is provided with at least one moving mechanism 54, 64 for moving the fluid handling device 10 and the container C separately relative to each other between the following two positions:

[0056] a fluid introduction position, wherein the needle-shaped fluid handling body 12 protrudes into the interior volume of the container C for introducing fluid material therein, and

[0057] a beverage dispensing position in which the needle-shaped fluid handling body 12 is at least partially withdrawn from the interior volume of the container C to allow a beverage product to be dispensed from the container C through the outlet member 20. Optionally, in the beverage dispensing position, a fluid substance may be simultaneously introduced into the container C by the needle-shaped fluid handling body 12 while the beverage product is being dispensed from the container C. Optionally, during the fluid introduction position, the fluid substance and / or the beverage product may partially leak downwardly over the outlet member 20 of the fluid handling body 12.

[0058] According to a preferred aspect of the present invention, the needle-shaped fluid handling body 12 further comprises at least one sealing member 22 to be engaged with the container C for preventing the fluid substance and / or beverage product from leaking from the container C at least when the fluid substance is introduced into the container C. In other words, when the needle-shaped fluid handling body 12 is provided with the sealing members 22, in the fluid introduction position, these sealing members 22 engage with the container C to prevent the fluid substance and / or beverage product from being dispensed from the container C ( 7A to 7C In the beverage dispensing position, these sealing members 22 do not engage with the container C to allow complete dispensing of the beverage product from the container C ( Figures 8A to 9C ). However, it should be noted that the sealing member 22 is not an essential feature of the present invention.

[0059] according to Figure 2 9 , the needle-shaped fluid handling body 12 includes an inlet portion 14 and an outlet portion 16. An inlet member 18 for introducing a fluid substance into the container C is provided at the inlet portion 14 of the needle-shaped fluid handling body 12, while an outlet member 20 for dispensing a beverage product from the container C is provided at the outlet portion 16 of the needle-shaped fluid handling body 12. The inlet member 18 and the outlet member 20 of the needle-shaped fluid handling body 12 are preferably separate from each other, and a single fluid handling device 10 is used to allow a mixed fluid substance (typically hot water) to be introduced into the container C and a beverage product formed in the container C to be dispensed.

[0060] Preferably, according to Figure 29 , the needle-shaped fluid treatment body 12 includes a first end portion 26 and a second end portion 28, the first end portion being disposed at the inlet portion 14 of the needle-shaped fluid treatment body 12 and being configured to open (e.g., by tearing, piercing, and / or penetrating) a specific portion of the container C, and the second end portion being disposed at the outlet portion 16 of the needle-shaped fluid treatment body 12. The needle-shaped fluid treatment body 12 also includes at least one inlet conduit 30 disposed therein. The inlet conduit 30 is in fluid communication with the first end portion 26 of the needle-shaped fluid treatment body 12 and the second inlet conduit 36 of the second fluid treatment body 34, as will be described in detail below. The inlet conduit 30 and the first end portion 26 are thus included in the inlet member 18 of the needle-shaped fluid treatment body 12. More precisely, the inlet conduit 30 is a closed conduit in the form of a tube that is embedded in the needle-shaped fluid treatment body 12, which allows the fluid substance to be inserted into the container C without being exposed to air.

[0061] like Figure 2 As shown in the embodiment of the fluid handling device 10 of FIG9 , the sealing member 22 is preferably disposed between a first end portion 26 and a second end portion 28 of the needle-shaped fluid handling body 12. Preferably, the needle-shaped fluid handling body 12 is a vertically oriented elongated body, more preferably a pointed body, wherein its first end portion 26, its second end portion 28, and the sealing member 22 are coaxially arranged about a vertical axis A. More preferably, as shown in the accompanying drawings, the first end portion 26 is oriented upward relative to the position of the fluid handling device 10 within the beverage preparation machine 1. Even more preferably, the first end portion 26 and / or the second end portion 28 of the needle-shaped fluid handling body 12 are each a pointed portion. Thus, the pointed first end portion 26 is configured to open a specific portion of the container C, for example, by penetration, puncture, or tearing, in order to inject a fluid substance therein, as will be explained in detail below. The pointed second end portion 28 is oriented downward relative to the position of the fluid handling device 10 within the beverage preparation machine 1 so as to precisely direct the flow of beverage product into the user's cup.

[0062] The outlet member 20 of the fluid treatment device 10 includes a second end portion 28 of the needle-shaped fluid treatment body 12 and at least one outlet conduit 32 that is different from the inlet conduit 30 of the inlet member 18. More specifically, according to Figure 2 9 , each outlet conduit 32 is obtained in the form of a slotted channel provided on the outer surface of the needle-shaped fluid treatment body 12. Therefore, each slotted channel is in fluid communication with the second end portion 28 of the needle-shaped fluid treatment body 12.

[0063] Preferably, the sealing member 22, which is configured to engage with the container C to prevent leakage of a fluid substance and / or beverage product from the container C when the fluid handling device 10 is in operation, is comprised of an enlarged portion 22A of the needle-shaped fluid handling body 12. More specifically, the enlarged portion 22A of the needle-shaped fluid handling body 12 is included between the first end portion 26 and the second end portion 28 of the needle-shaped fluid handling body 12 and has a cross-sectional area that is greater than any cross-sectional area of the portion of the needle-shaped fluid handling body 12 included between the first end portion 26 and the enlarged portion 22A itself. The enlarged portion 22A of the fluid handling body 12 may be at least partially covered with an elastic material to ensure better sealing properties. Thus, the enlarged portion 22A of the needle-shaped fluid handling body 12 is configured to adhere to the wall of the container C at the portion of the container C opened by the first end portion 26 of the needle-shaped fluid handling body 12.

[0064] Conveniently, each outlet conduit 32, in the form of a slotted channel, is provided on the outer surface of the vertically oriented needle-shaped fluid-handling body 12, in the portion thereof between its first end portion 26 and its enlarged portion 22A. Thus, a beverage guide element 50 for guiding beverage to the second end portion 28 of the needle-shaped fluid-handling body 12 is provided between the enlarged portion 22A and the second end portion 28. Preferably, the beverage guide element 50 has a tapered cross-sectional area that decreases from the enlarged portion 22A of the needle-shaped fluid-handling body 12 to the second end portion 28. More preferably, the beverage guide element 50 has a conical shape. Even more preferably, the beverage guide element 50 has a frustoconical shape with an additional pointed element at the outlet portion 16. Thus, the beverage product extracted from the container C is guided by the outlet conduit 32 to the second end portion 28 via the beverage guide element 50, so that the flow of beverage product is precisely directed into a user's cup placed below the beverage guide element 50.

[0065] The fact that the outlet member 20 of the fluid-handling device 10 is positioned externally relative to the needle-shaped fluid-handling body 12, and that it is provided in the form of a slotted channel, i.e., having an open cross-section rather than a closed loop cross-section (as is typically the case with conventional cylindrical channels), offers particular advantages when handling beverage products based on a mixture of a fluid substance and a soluble ingredient. Indeed, if the soluble ingredient contained in the container C primarily consists of solid particles, some of these solid particles (e.g., biscuit crumbs, etc.) retain their solid state even after mixing with the fluid substance (e.g., hot water), allowing for proper ingestion by the user. Therefore, the open cross-section of the outlet member 20 allows these particles to be delivered to the user's cup along with the fluid substance without the risk of clogging the otherwise designed cylindrical dispensing channel.

[0066] In addition, the slotted channel may have a variable open cross-section that increases or decreases from the first end portion 26 to the enlarged portion 22A of the needle-shaped fluid-handling body 12. In other words, the slotted channel may optionally be manufactured with a specific profile (i.e., a slope) from its top to its bottom so that, depending on the height position of the needle-shaped fluid-handling body 12 in the container C, the open cross-section of the slotted channel increases or decreases to accommodate the flow rate of the beverage product flowing out to the cup, and also to accommodate the fluid pressure inside the container C during mixing.

[0067] Optionally, the fluid treatment device 10 may be provided with at least one air or gas inlet aperture 24 in fluid communication with the inlet member 18 and in the Figure 2 9 , it is located on the needle-shaped fluid handling body 12 between the first end portion 26 and the sealing member 22. Figure 2 In the embodiment shown in FIG9 , the air or gas inlet hole 24 is in the form of a through-hole formed on the side wall of the needle-shaped fluid treatment body 12 and is placed in fluid communication with the inlet conduit 30 for fluid collection. As will be explained in detail below, the air or gas inlet hole 24 allows the inlet conduit 30 to be in contact with the external environment in certain operating states of the fluid treatment device 10, and allows a predefined amount of air or gas to be drawn in, mixed with the fluid substance, and introduced into the container C through the inlet conduit 30 by means of the Venturi effect.

[0068] In case the needle-shaped fluid handling body 12 is provided with the air or gas inlet hole 24, the movement mechanism 54, 64 of the beverage preparation machine 1 is configured for moving the fluid handling device 10 and the container C separately relative to each other in at least one of the following intermediate positions, namely:

[0069] - a first intermediate position in which the air or gas inlet aperture 24 is located outside the interior volume of the container C and the sealing member 22 (if provided) is not engaged with the container C ( Figures 8A to 8C ),as well as

[0070] - a second intermediate position in which the air or gas inlet aperture 24 is located within the interior volume of the container C and the sealing member 22 (if provided) is still not engaged with the container C ( Figures 9A to 9C ).

[0071] More specifically, in Figure 29 , the fluid treatment device 10 is configured to move between a first intermediate position and a second intermediate position to selectively achieve or not achieve the Venturi effect. In another possible embodiment, the fluid treatment device 10 is configured to always maintain its gas inlet hole 24 outside the interior volume of the container C to always achieve the Venturi effect. Preferably, in this possible embodiment of the fluid treatment device 10, the gas inlet hole 24 may be located between the sealing member 22 and the second end portion 28 of the needle-shaped fluid treatment body 12. More preferably, in this possible embodiment of the fluid treatment device 10, the sealing member 22 is not provided on the needle-shaped fluid treatment body 12.

[0072] The fluid treatment device 10 preferably includes a second fluid treatment body 34 connected to the needle-shaped fluid treatment body 12 described so far. More preferably, the second fluid treatment body 34 is integrally manufactured with the needle-shaped fluid treatment body 12 at its joint end 44. The second fluid treatment body 34 is internally provided with a second inlet conduit 36 that is placed in fluid communication with the inlet conduit 30 of the needle-shaped fluid treatment body 12.

[0073] According to a preferred aspect of the present invention, such as Figure 6B 、 Figure 7B 、 Figure 8B and Figure 9B , the second inlet duct 36 is a converging duct having a cross-sectional area that decreases toward the inlet duct 30. More specifically, the second inlet duct 36 is preferably provided with at least a first duct portion 38 having a first predefined cross-sectional area, and provided with a second duct portion 40 having a second predefined cross-sectional area that is smaller than the first predefined cross-sectional area of the first duct portion 38. The second duct portion 40 is placed downstream of the first duct portion 38 and is in fluid communication with the inlet duct 30 obtained in the needle-shaped fluid treatment body 12 of the fluid treatment device 10.

[0074] In addition, at least one through hole 42 may be interposed between the inlet conduit 30 obtained in the needle-shaped fluid-treatment body 12 and the second inlet conduit 36 obtained in the second fluid-treatment body 34. Conveniently, the average cross-sectional area of the through hole 42 is smaller than the average cross-sectional area of the inlet conduit 30 of the needle-shaped fluid-treatment body 12 and the average cross-sectional area of the second inlet conduit 36 of the second fluid-treatment body 34.

[0075] The specific construction of the second fluid handling body 34 with its convergent cross-sectional profile and the presence of the through-hole 42 allow the speed of the fluid substance introduced into the container C by the fluid handling device 10 to be appropriately set. In fact, the convergent cross-sectional profile of the second fluid handling body 34 allows the speed of the fluid substance pumped into the fluid handling device 10 by the beverage preparation machine 1 to be increased. In addition, the through-hole 42 is provided for further increasing the speed of the fluid substance before it flows out of the inlet duct 30 of the needle-shaped fluid handling body 12. The presence of the through-hole 42 ensures good dissolution of the ingredients and reconstitution of the beverage product. The through-hole 42 limits the flow rate and pressure of the fluid substance during the reconstitution of the beverage product. The through-hole 42 may also have an "anti-backflow" function so as to reduce the risk of the fluid substance returning from the container C into the fluid line consisting of the sequence of the inlet duct 30, the through-hole 42 itself and the second inlet duct 36.

[0076] According to a preferred aspect of the present invention, the second fluid handling body 34 is arranged orthogonally relative to the needle-shaped fluid handling body 12, so that the inlet conduit 30 is substantially orthogonal relative to the second inlet conduit 36. Thus, when the fluid handling device 10 is properly connected to the beverage preparation machine 1 in its operating state, the needle-shaped fluid handling body 12 is arranged orthogonally relative to the needle-shaped fluid handling body 12. Figure 4 1 (shown in FIG) with its first end portion 26 at the top and its second end portion 28 at the bottom, while the second fluid treatment body 34 is substantially horizontal. As a result, in the operating state of the fluid treatment device 10, the inlet conduit 30 is oriented in a substantially vertical direction, while the second inlet conduit 36 is oriented in a substantially horizontal direction.

[0077] The second fluid-handling body 34 may be provided with a coupling portion 46 for removably coupling the fluid-handling device 10 to the beverage preparation machine 1. This removable coupling allows the fluid-handling device 10 to be removed from the beverage preparation machine 1 and washed separately from the machine 1, for example in a dishwasher. The coupling portion 46 is positioned at the opposite end of the second fluid-handling body 34 relative to its end 44 where it is joined to the needle-shaped fluid-handling body 12. As shown in the figures, the coupling portion 46 may be internally provided with at least one third inlet conduit 48 having an average cross-sectional area greater than the average cross-sectional area of the second inlet conduits 36 of the second fluid-handling body 34, in order to further increase the velocity of the fluid material before it exits the inlet conduit 30 of the needle-shaped fluid-handling body 12.

[0078] exist Figures 6A to 6C, a non-operating state of the fluid treatment device 10 is shown in a first perspective view, a cross-sectional view, and a second perspective view, respectively. In this non-operating state, the fluid treatment device 10 is shown outside of a container C, i.e., before a fluid substance is introduced into the container C through the inlet member 18. In other words, in this non-operating state, no fluid substance or other material is transferred through the inlet member 18 and the outlet member 20 of the fluid treatment device 10.

[0079] exist 7A to 7C , a first operating state of the fluid treatment device 10, i.e., a fluid introduction position, is shown in a first perspective view, a cross-sectional view, and a second perspective view, respectively. In this first operating state, at least a portion of the needle-shaped fluid treatment body 12 protrudes into the interior of the container C, allowing fluid material to be introduced therein through the inlet member 18.

[0080] In this fluid introduction position, the sealing member 22, i.e. Figure 2 9 , the enlarged portion 22A of the needle-shaped fluid-handling body 12 contacts the bottom wall of the container C. In this embodiment, the outlet member 20, i.e., an outlet conduit 32 in the form of a slotted channel, is provided on the sidewall of the needle-shaped fluid-handling body 12 at a position higher than the enlarged portion 22A of the needle-shaped fluid-handling body 12. In this manner, in the fluid introduction position of the fluid-handling device 10, the outlet conduit 32 is fully inserted into the container C, and due to the sealed engagement between the sealing member 22 and the container C, no fluid substance and / or other substances are allowed to leak or leak only a small amount of fluid from the container C.

[0081] exist Figure 2 In the embodiment shown in FIG9 , the needle-shaped fluid treatment body 12 of the fluid treatment device 10 is a pointed body having a first pointed end portion 26 provided at its inlet portion 14. Thus, this pointed end portion 26 is configured to penetrate and / or pierce and / or tear open a specific portion of the container C to inject the fluid substance therein. However, as will be explained below, other embodiments of the needle-shaped fluid treatment body 12 are conceivable, in which the inlet portion 14 is configured in a different manner for achieving the first operating state of the fluid treatment device 10 in a different manner, for example Figures 10 to 14 The embodiments are described in more detail below.

[0082] In the embodiment of the beverage preparation machine 1 shown in the accompanying drawings, the container C is preferably made of a multilayer flexible material, more preferably essentially made of paper layers. Preferably, this container C is therefore provided internally with an additional layer L of a substantially rigid material in its lower part, i.e. at the part engaged by the fluid handling device 10. This substantially rigid material may be, for example, a compostable plastic that is able to form a barrier against oxygen and moisture. Compostable means that the entire container C can be discarded after use together with the fruit and vegetable peels. However, other embodiments of the container C are also possible, but it is preferred that, in the embodiment of the beverage preparation machine 1 shown in the accompanying drawings, such a container C has a substantially rigid part in the contact area with the needle-shaped fluid handling body 12, because the relative rigidity of at least part of the container C is advantageous for cooperating with the sealing member 22 of the needle-shaped fluid handling body 12.

[0083] The preferably substantially rigid layer of the container C is provided with an injection hole at its bottom, the cross-sectional shape of which (for example, a circular cross-sectional shape) matches the cross-sectional shape of the needle-shaped fluid handling body 12, i.e. the cross-sectional shape of the pointed body. In the non-operating state of the fluid handling device 10, the injection hole is partially closed by the bottom portion of the multi-layer flexible material of the container C (preferably in an airtight mode). In the case of a circular cross-sectional shape, the diameter of the injection hole is larger than the average diameter of the pointed body, but smaller than or equal to the maximum diameter of the sealing member 22, i.e. the enlarged portion 22A of the pointed body (if these sealing members 22 are provided on the needle-shaped fluid handling body 12). By this construction, during the movement of the needle-shaped fluid handling body 12 toward the container C, the needle-shaped fluid handling body 12 can be introduced into the container C through the injection hole (destroying or tearing off the portion of the multi-layer flexible material that closes the injection hole) until the sealing member 22 has reached its sealing position relative to the circumferential edge of the injection hole. In this sealing position, further movement between the needle-shaped fluid handling body 12 and the container C is not allowed, thereby obtaining the sealing member 22 as described above and as shown in the figure. 7A to 7C Fluid introduction locations are shown.

[0084] exist Figures 8A to 8C , a first intermediate position of the fluid treatment device 10 is shown in a first perspective view, a cross-sectional view, and a second perspective view, respectively. In this first intermediate position, at least a portion of the needle-shaped fluid treatment body 12 still protrudes into the interior of the container C, similar to what occurs in the fluid introduction position described above, but the sealing member 22 is not in close contact with the bottom wall of the container C. In other words, in this first intermediate position, a smaller portion of the fluid treatment body 12 protrudes into the container C than in the fluid introduction position (this fact can also be seen from the fact that Figure 7B and Figure 8BAs can be seen from the comparison between the two), a fluid substance can be introduced into the interior of the container C through the inlet member 18, and at the same time, the resulting beverage product can flow out through the outlet member 20.

[0085] More specifically, in this first intermediate position, the needle-shaped fluid handling body 12 protrudes into the interior of the container C, such that its air or gas inlet hole 24 remains outside the container C. Therefore, in this first intermediate position, the injection of air or gas into the container C is possible simultaneously with the injection of the fluid substance via the Venturi effect. It should be noted that the Venturi effect achieved by the simultaneous injection of the fluid substance and air or gas into the container C only occurs when the fluid substance is injected into the container C via the inlet member 18. Indeed, once the injection of the fluid substance into the container C via the inlet member 18 ceases, the Venturi suction effect via the air or gas inlet hole 24 ceases to operate. Therefore, the Venturi effect does not occur only in the extraction mode, i.e., when the beverage product has been fully prepared and is flowing out via the outlet member 20.

[0086] Essentially, the Venturi effect is the fact that when a fluid material circulates at high speed within the inlet member 18 of the fluid handling device 10, it draws in a certain amount of air or gas through the air or gas inlet opening 24. This is due to suction, a physical property known in the art of fluid mechanics. As the air or gas is drawn (i.e., pumped) into the flow of fluid material injected into the container C, it also mixes with the soluble ingredients. This mixture of soluble ingredients, fluid material, and air or gas produces the foaming effect required for foamed beverage products (such as foamed milk, chocolate syrup, etc.).

[0087] Obviously, the suction effect of air or gas and fluid material can only work when the air or gas inlet hole 24 is located outside the container C. Therefore, if the needle-shaped fluid treatment body 12 is fully inserted into the container C so that the air or gas inlet hole 24 is located inside the container C, the Venturi effect can be stopped, for example in the second intermediate position of the fluid treatment device 10 described below.

[0088] exist Figures 9A to 9C , a second intermediate position of the fluid treatment device 10 is shown in a first perspective view, in a cross-sectional view and in a second perspective view, respectively. This second intermediate position is substantially similar to the first intermediate position described above, except for the fact that the needle-shaped fluid treatment body 12 is inserted into the container C so that the air or gas inlet hole 24 is also located inside the container C (see in particular Figure 9B ), and the sealing member 22 is again not in close contact with the bottom wall of the container C.

[0089] Thus, in this second intermediate position, a fluid substance can be introduced into the interior of the container C through the inlet member 18, and at the same time, the resulting beverage product can flow out towards a cup through the outlet member 20. However, in this second intermediate position, no Venturi effect occurs, and air or gas is not injected into the container C through the air or gas inlet hole 24, but during the injection phase, only the fluid substance is introduced into the container C.

[0090] Regardless of the Venturi effect, in both the first and second intermediate positions, the fluid substance is injected into the container C through the inlet member 18 of the needle-shaped fluid handling body 12. The fluid substance injected into the container C is mixed with a soluble ingredient (e.g., coffee powder) to produce a beverage product. Furthermore, in these intermediate positions, the needle-shaped fluid handling body 12 is partially located outside the container C, so that the dispensing slot-shaped channel is always at least partially located outside the container C (i.e., the dispensing slot-shaped channel is open), and thus enables the beverage product to flow from the container C into the user's cup. Therefore, while the fluid substance is injected into the container C, the beverage product is also dispensed into the user's cup.

[0091] Figures 10 to 14 Other embodiments of the fluid treatment device 10 are shown. In these embodiments, the fluid treatment body 12 has the same Figure 2 More precisely, the outlet member 20 is different from the outlet conduit 32 in the form of a slotted channel, since the function of the outlet member 20 can be performed by other outlet guide elements. Figure 13 In the embodiment shown in FIG, the outlet member 20 further includes at least one outlet conduit arranged inside the fluid treatment body 12, similar to the first inlet conduit 30. In other embodiments, these outlet guiding elements may be the outer surface of the fluid treatment body 12 and / or one or more outlet conduits arranged inside the fluid treatment body 12 and / or one or more outlet conduits arranged on the outer surface of the fluid treatment body 12.

[0092] exist Figures 10 to 14 In the embodiment of the present invention, no specific sealing member is provided on the outer surface of the fluid treatment body 12. However, a specific sealing function can be performed by a specific portion of the outer surface of the fluid treatment body 12 located below the inlet member 18 (not necessarily an "enlarged" portion). If provided, this specific portion of the outer surface of the fluid treatment body 12 can also be configured to adhere to the wall of the container C at the portion of the container C opened by the first end portion 26 of the fluid treatment body 12. Preferably, in Figures 10 to 14 In the embodiment of FIG. 5 , no sealing member 22 of any kind is provided between the fluid handling body 12 and the container C, with the result that leakage of fluid substance into the user's cup during beverage preparation is small or negligible.

[0093] Advantageously, in Figures 10 to 14 In the embodiment of the invention, the outer surface of the fluid treatment body 12 is tapered. Advantageously, the inlet conduit of the second fluid treatment body 34 has a cross-sectional area that decreases towards the inlet conduit 30, as for Figure 2 9 . In addition, it should be noted that at least one of the first end portion 26 and / or the second end portion 28 of the fluid treatment body 12 may not be pointed, but may be a substantially flat portion or a slightly curved portion. In fact, the substantially flat first end portion 26 of the fluid treatment body 12 can also effectively open a specific portion or wall of the container C, for example by pushing this portion or wall into the interior of the container C and / or removing or unsealing the portion or wall from the container C. In this case, the container C is designed so that its specific portion or wall is welded or glued to the bottom of the container so that it covers and closes the through-hole provided at this bottom. Alternatively, this specific portion or wall may be provided with a weakened profile that allows the first end portion 26 of the fluid treatment body 12 to be removed or unsealed and / or pushed into the interior of the container C. According to this embodiment without a pointed first end portion 26, the fluid treatment body 12 may have any suitable shape, not necessarily a needle shape.

[0094] exist Figures 10 to 14 In the embodiment of the invention, the optional gas inlet port 24 may be positioned on the fluid handling device 10 in such a way that it remains outside the container C having the venturi effect, e.g. Figure 2 9, or may be located inside the container C without a Venturi effect, e.g. Figure 2 To the third operating state of the embodiment of Figure 9. Preferably, in Figures 9 and Figure 10 In the embodiment of the present invention, the gas inlet hole 24 is positioned on the second fluid treatment body 34 of the fluid treatment device 10 and is always connected to the second fluid treatment body 34 through a dedicated conduit 24A (such as Figure 12 9 and 10 ) are in fluid communication with the inlet member 18 of the fluid handling body 12. Figure 10 In this embodiment, the gas inlet hole 24 is located on the fluid treatment device 10 so that the gas inlet hole 24 always remains outside the container C, thereby always providing a Venturi effect. Figures 11 to 13 In the embodiment of the present invention, the gas inlet hole 24 is located at the second end portion of the fluid treatment body 12, that is, the lower portion of the fluid treatment body 12, and is always connected to the gas inlet hole 24 through a dedicated conduit 24A (such as Figure 14 ) is in fluid communication with the inlet member 18 of the fluid handling body 12. Figures 11 to 13In this embodiment, the gas inlet hole 24 is located on the fluid treatment device 10 so that it always remains outside the container C, thereby always providing a Venturi effect. According to further modifications of the fluid treatment device 10 not shown in the drawings, the optional gas inlet hole 24 can be arranged on the fluid treatment body 12 and / or on the second fluid treatment body 34 at different positions so that it always remains outside the container C, thereby always providing a Venturi effect.

[0095] In view of all the embodiments described so far, the term "opening" when referring to a specific part or wall of a container C should be intended to mean: penetrating, piercing, tearing, splitting, or unsealing this specific part or wall of the container C before introducing the fluid substance into the container C, or pushing the specific part or wall into the interior of the container C, or opening the specific part or wall in any equivalent manner.

[0096] Preferably, the container C is a disposable container, such as a bag or pouch or any known container having at least a flexible side wall. The container C may also be any other openable (e.g., pierceable) closed packaging, such as a capsule, a pod, a pad, a bottle, a flow bag, a can, etc. The container C may alternatively be a multi-dose container having, for example, a large storage compartment for storing several doses of an ingredient and a dosing and mixing chamber capable of receiving one dose when the ingredient is transferred from the storage compartment.

[0097] 15A to 15D An embodiment of a container holder 7 for a beverage preparation machine 1 is disclosed. Since this container holder 7 is of a type known in the prior art and comprises a seat 8 for supporting a container C, it will not be described in detail. Figures 15A to 15B As shown, the beverage preparation machine 1 may be provided with a first locking mechanism 52 for selectively locking / unlocking the container C relative to the container holder 7 when the container C is received in the seat 8 of said container holder 7. 15A to 15D In the embodiment of FIG. 1 , the container holder 7 is fixed relative to the fluid handling device 10 .

[0098] exist 15A to 15D and 16A to 16B In the illustrated first preferred embodiment of the beverage preparation machine 1 , the fluid handling device 10 is movable relative to the container C, which is fixed relative to its container holder 7 and the beverage preparation machine 1 . 15A to 15D In this particular embodiment of the beverage preparation machine 1, the movement mechanism 54, 64 comprises a first actuating member 54 ( 16A to 16B ), for moving the fluid handling device 10 relative to the container C between at least a fluid introduction position and a beverage dispensing position, or vice versa. 15A to 15DIn this particular embodiment, the first locking mechanism 52 of the container C relative to the container holder 7 comprises a first gear and / or lever mechanism 56. 15A to 15D In this particular embodiment of the present invention, the first gear and / or lever mechanism 56 consists of at least one lever 78 rotatable around a corresponding hinge 80 obtained on a fixed part of the beverage preparation machine 1. Thus, the first gear and / or lever mechanism 56 is movable relative to the fixed part of the beverage preparation machine 1 and at least one tooth 58 provided on the lever 78 is capable of engaging with at least one corresponding hole 60 ( FIG. 15C to FIG. 15D ) is selectively engaged. The container C can be separated from the container holder 7 and, therefore, from the beverage preparation machine 1, only when the teeth 58 are in the non-engaged position relative to the corresponding holes 60. It should be noted that this embodiment of the first gear and / or lever mechanism 56 is described and shown for illustrative purposes only, and further embodiments of this first gear and / or lever mechanism may be provided.

[0099] In the embodiment of the fluid handling device 10 which is movable relative to the container C, 16A to 16B In the embodiment of FIG, the first actuating member 54 includes a second gear and / or lever mechanism 62 connected to the fluid handling device 10. 16A to 16B In this particular embodiment, the second gear and / or lever mechanism 62 is comprised of a plurality of gears 74 that actuate at least a rod 76 connected to the fluid treatment device 10. The second gear and / or lever mechanism 62 is configured to move the fluid treatment device 10 relative to the container C along the vertical axis A of the needle-shaped fluid treatment body 12. More specifically, as 16A to 16B As shown, rotation of gear 74 causes corresponding vertical movement of rod 76, which in turn causes fluid treatment device 10 to rotate along axis A. Figure 16A The joint position (ie, 7A to 7C Fluid introduction location) and Figure 16B The non-engaged position (i.e., Figures 6A to 6C In addition, the rotation of the gear 74 and the corresponding vertical movement of the rod 76 also cause the fluid treatment device 10 to move vertically along the axis A to Figures 8A to 8C the first intermediate position (i.e. the intermediate position where the Venturi effect is activated) and, if necessary, to the Figures 9A to 9C It should be noted that this embodiment of the second gear and / or lever mechanism 62 is described and shown for illustrative purposes only, and that additional embodiments of this second gear and / or lever mechanism may be provided.

[0100] exist 17A to 17B and Figure 18In the second preferred embodiment of the beverage preparation machine 1 shown, the fluid handling device 10 is fixed relative to the container holder 7, while the container C is movable relative to both the container holder 7 and the fluid handling device 10. In this particular embodiment, the movement mechanism 54, 64 of the beverage preparation machine 1 includes a second actuating member 64 for moving the container C relative to the fluid handling device 10. More specifically, since in this embodiment of the beverage preparation machine 1, the container C can only be moved relative to the fluid handling device 10, the movement mechanism 54, 64 is configured to move the container C from Figures 6A to 6C The inoperative state of the actuator initiates movement of the container C between a fluid introduction position and a beverage dispensing position, or vice versa.

[0101] exist 17A to 17B and Figure 18 In the embodiment of FIG. 1 , a container C is shown movable relative to the fluid handling device 10 , and the second actuating member 64 includes a container support 66 and a third gear and / or lever mechanism 68 . 17A to 17B and Figure 18 In this particular embodiment, the third gear and / or lever mechanism 68 is comprised of a plurality of gears 82 that rotate to drive the rotational and translational movement of the connecting rod 84. The container support 66 is actuated by the third gear and / or lever mechanism 68 for moving the container C relative to the container holder 7 and relative to the fluid treatment device 10 along the vertical axis A of the needle-shaped fluid treatment body 12. Figure 18 As shown, the container support 66 is provided with a second locking mechanism 72 comprising, for example, at least one pin 70 selectively engageable with at least one corresponding hole 60 provided in the container C. Operationally, rotation of the gear 82 causes the gear 82 connected to the second locking mechanism 72 (e.g., Figure 18 The rotation and translation of the connecting rod 84 (shown) in turn causes the vertical movement of the container support device 66 and its corresponding second locking mechanism 72, that is, vertical movement along the vertical axis A. Since the pin 70 of the second locking mechanism 72 engages with the corresponding hole 60 provided in the container C, the container C is 6A to 9C All positions shown are vertically movable relative to the fluid handling device 10 (fixed). It should be noted that the container C can only be separated from the container holder 7, and thus from the beverage preparation machine 1, in the non-engaged position of the pins 70 relative to the corresponding holes 60. It should also be noted that in this embodiment, other locking mechanisms may be provided instead of Figure 18 The second locking mechanism 72. For example, Figures 15A to 15C (wherein a movable fluid treatment device 10 and a fixed container C are shown) the first locking mechanism 52 shown can also be used instead of 17A to 17B and Figure 18(wherein a fixed fluid handling device 10 and a movable container C are shown) the second locking mechanism 72 associated with the third gear and / or lever mechanism 68. For the same reason, 17A to 17B and Figure 18 The second locking mechanism 72 shown in FIG. 1 can also be used instead of Figures 15A to 15C Finally, it should be noted that this embodiment of the third gear and / or lever mechanism 68 is also described and shown for illustrative purposes only, and that additional embodiments of this third gear and / or lever mechanism may be provided.

[0102] Last but not least, in a preferred embodiment of the present invention, in addition to the first container holder and fluid handling device described in detail above, the beverage preparation machine 1 also includes a second container holder and fluid handling device (not shown in the drawings). Preferably, the second fluid handling device is fluidically connected to the same fluid circulation system that is also connected to the first fluid handling device described above. This has the advantage that the machine is less complex and expensive to manufacture and operate. However, of course, a second fluid circulation system that is independent of the first fluid circulation system but constructed similarly to the first fluid circulation system can be included in the same beverage preparation machine.

[0103] In this embodiment, it is preferred that the first container adapted to be inserted into the first container holder and processed by the first fluid handling device is a pouch (embodiments of which are described above) configured to contain a soluble ingredient for mixing with a fluid (e.g., water), such as a dairy composition, a tea-based composition, a chocolate-based composition, a soup, a fruit composition such as a smoothie, etc. The pouch may also contain a leaf tea ingredient, or a plant-based soluble or infusible ingredient. Typically, fluid processing in a pouch-type container is performed at low pressure, as provided in the description above.

[0104] The second container, adapted to be inserted into the second container holder and processed by the second fluid-handling device, is preferably a rigid or semi-rigid container, such as a capsule or pod, containing an ingredient adapted to be extracted at a higher fluid pressure than that used by the first fluid-handling device. Such an ingredient is typically roast and ground coffee, which is extracted by circulating pressurized water therethrough according to coffee extraction techniques known in the art. The fluid circulated through the coffee grounds is preferably, but not necessarily, hot water (typically, hot water for coffee extraction is circulated through the ingredient at a temperature of 75°C to 95°C). However, room temperature water or even cold water can also be used for so-called "cold brew" coffee preparation. In this case, the container holder is preferably a brewing chamber comprising two elements that are movable relative to one another to enable the chamber to be opened for insertion or removal of the container and then closed for extraction of the ingredient contained therein. No further details are provided in this specification, as such brewing chambers are well known in the art of beverage machines.

[0105] In order to control the preparation of the different ingredients, the beverage machine comprises a control panel (attached to the machine housing, or in a remote device) and a control chip board capable of operating a fluid processing device, and a fluid circulation system for preparing beverages from a first container and a second container simultaneously or sequentially.

[0106] It should be understood that various changes and modifications to the presently preferred embodiment of the beverage preparation machine 1 described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the scope of the invention as encompassed by the appended claims.
