The present disclosure refers to the field of devices of supplying of substances for food applications and concerns the field of machines for filling capsules under pressure.
In detail, the present disclosure concerns a capsule for beverages, and concerns also a machine for filling capsules and an associated method.
During the last years have been spreading devices for the preparation of beverages starting from capsules. These devices for the preparation of beverages quickly spread for home applications and for small businesses, subsequently. In particular, are known machines of “table-top” type that contain a small water tank and that supply coffee, tea or infusions. These capsules, that in the present disclosure will be defined capsule for beverages, are typically configured for containing substances in granules or powder. Coffee, tea or infusion is supplied by making flow, in use, part of the water contained in the small tank of the machine within the capsule, realizing the beverage. Typically, the water that is flown within the capsule is at first heated and this allows an appropriate extraction of flavors of coffee, tea or infusion. In order to flow the water within the capsule, typically the capsule is perforated in a predetermined position; some capsules show an outlet pipe from which the beverage can flow.
There are also known carbonation devices, among which the most famous are the Sodastream™ devices. These devices are conceived with the purpose of injecting carbon dioxide in the water, in order to render it gasified.
The water is at first positioned in a bottle that is firmly connected to the carbonating device. An injector, in use partially introduced under the maximal height reached by the water in the bottle, injects—upon control of the user—a determined amount of carbon dioxide in order to gasify the water.
There are also known substantially homemade filters for the removal of determined minerals from the water, configured for allowing the user to drink water of which the content, for example, of limestone, or polluting substances is significantly reduced by means of filtering processes according to various technologies.
In the specific field of water carbonating devices of known type, and more generally in the field of supplying devices of drinking water, until now no one has raised the issue of the organoleptic properties of the water and of its correct mineral content.
The Applicant has observed that exists an interest of the market towards the production of waters, for example to drink or destined to sanitary applications, whose mineral content can be chosen and appropriately selected by the user.
In particular the Applicant has observed that determined waters, poor in minerals or previously demineralized, can be mineralized through mineralized solutions contained in determined capsules.
In particular the Applicant has conceived a capsule for beverages which, in use, contains a mineralized solution destined to be used for mineralizing waters destined to the human consumption.
The Applicant has also conceived a machine for filling capsules, and an associated method, which are destined to allow the mineralization of waters destined to the human consumption.
A purpose in particular of the present disclosure is to describe an innovative capsule for beverages, which can allow the realization of waters mineralized with mineralized solution of different composition.
A purpose of the present disclosure is also to describe an innovative capsule for beverages, which is of easy and safe use.
A purpose of the present disclosure is also to describe a capsule for beverages that allows an efficient extraction of substantially the whole content thereof.
A purpose of the present disclosure is also to describe a machine for filling the capsules for beverages which allows to fill—at least partially—capsules for beverages with mineralized solutions of different composition.
A purpose of the present disclosure is to describe a machine for filling the capsules for beverages which allows to fill at least a capsule for beverages in a substantially quick, easy and safe way.

The object of the present disclosure is now described referring to the attached figures, which are related to specific, and non-limiting, embodiments. A short description of the figures is hereinafter indicated.
This first part of the detailed description refers to a device for water treatment and associated method. The device for water treatment can be integrated in a machine for the loading of capsules for beverages that is described in its entirety in the successive portions of the detailed description. Equivalently, the water treatment method here described can be used in, in particular be a part of, a method for filling capsules for beverages that will be overall described further on in the description.
In
The device 1 comprises a container 2 configured for containing, in use, a predetermined amount of water 100 to mineralize, in particular through a predefined supply of minerals.

An upper wall is joined to the lateral wall 3 in substantial correspondence of a substantially upper end portion thereof, in particular of an upper end portion thereof.
Preferably, but in a non-limiting extent, the container 2 is a container realized in metallic material; the use of metallic material allows to advantageously withstand high pressures the container 2. Furthermore, the container 2 realized in metallic material is acid resistant and releases few ions or substances into the water. In an embodiment, the container 2 is realized in steel inox, which is a metallic material compatible with the treatment of water destined to human consumption. Alternatively, the container 2 can be realized in plastic material, sufficiently resistant and compatible with the treatment of water destined to human consumption.
The container 2 comprises a first opening 10 positioned in correspondence of a lower portion; the first opening 10 is destined to allow an extraction of the water 100 contained in the container 2. In a non-limiting embodiment, the first opening 10 is positioned in a bottom portion of the container 2.
The container 2 comprises a second opening 6 positioned in correspondence of an upper portion thereof; la second opening 6 is destined to allow an introduction of the water 100 in the container 2. In a non-limiting embodiment, the second opening 6 is positioned in a head portion of the container 2. An axis X of the container 2, that in use is vertically oriented, is preferably the axis that joins the first opening 10 with the second opening 6.
The device 1 comprises a gas supplying pipe 7, in particular a mineral solubilisation gas G supplying pipe. This gas supplying pipe 7 is introduced for a determined portion in the cavity of the container 2 and here shows an orifice destined to produce in use a great amount of little gas bubbles dispersing in the water 100. In
In a non-limiting embodiment, the gas supplying pipe 7 can be equipped with a gas filter, configured for allowing a final filtration of the gas before the introduction into the container 2.
The device 1 comprises also at least a supply input 14 of a mineralizing substance S to solubilize in water 100. The supply input 14, in a non-limiting embodiment, is positioned in correspondence of the lateral wall 3; alternatively, the supply input 14 can be positioned in correspondence of the head wall. Preferably, in use a height h2 separates the supply input 14 (placed at a higher height) with respect to the water 100 (placed at a lower height). The supply input 14 is specifically designed to allow the introduction of a mineralizing substance S that, reacting with the mineral solubilization gas G present in water 100, determines the mineralization of water 100 itself with a solubilized compound. A positioning of the supply pipe 14 above the height at which the water 100 is located allows to introduce the mineralizing substance S at a later time than the introduction of the water 100 to solubilize.
The device 1 further comprises a suction pipe 15, that preferably—but in a non-limiting extent—is positioned in correspondence of the head wall of the container 2 or, anyway, at a height higher with respect to the height in use assumed by the water 100.

The dispenser 6g, 6h through said substantially spheroidal shape or through other shapes, can be configured for directing a water deliver along a plurality of directions, in particular a rain spray or a nebulization also upwards or toward the lateral wall 3.
As it is possible to observe from
The device 1 object of the present disclosure also comprises a water recirculation system 9, 11, in turn comprising a pipe 9 and a pump 11. The pipe 9 is connected between the first opening 10 and the second opening 6, and at least in an operating configuration that will be better described hereinafter, allows to realize a closed water recirculation circuit within the container 2. This closed recirculation circuit is clearly insulated from the external environment. Although this has not to be understood in a limiting way, in an embodiment the pipe 9 is realized in metallic material, optionally in steel and preferably in stainless steel.
The pump 11 is positioned in correspondence of a predetermined position of the pipe 9, and is configured for forcing a water recirculation within the pipe 9, in particular forcing a flow of water 100 starting from the first opening 10 toward the second opening 6.
The pump 11 can assume any shape and be of any type; for example, and not limited thereto, this pump 11 can be an impeller or lobes rotating pump. The pump 11 is preferably an electrically actuated pump.
Optionally an auxiliary emptying pipe 8b, provided with the purpose of extracting at least part of the water 100 that in use is contained in the container 2, can be installed in correspondence of pipe 9; preferably the auxiliary emptying pipe 8b is connected downstream of the pump 11. In a non-limiting embodiment, the auxiliary emptying pipe 8b is provided with a control valve that can be actuated through an operating lever or through a servo-actuator. The auxiliary emptying pipe 8b can be present as an alternative to the main emptying pipe 8a.
In a preferred and non-limiting embodiment, the device 1 also comprises at least a cooling and/or thermal insulating device 12, 13a, 13b arranged in correspondence of at least one between the water recirculation system 9, 11 or said container 2 and destined to determine a cooling of the container 2 and/or of the water 100 in use contained in the container 2 at a temperature T1 optimal for the absorption of said mineralization gas G and/or destined to keep said cooling of the container 2 and/or of water 100 in use contained in the container 2. The cooling and/or thermal insulating device 12, 13a, 13b comprises an active cooler 13, 13a, 13b, positioned preferably in correspondence of pipe 9, or alternatively in at least one between the lateral wall 3 and the bottom portion 4 of container 2. The active cooler 13a, 13b can be for example a thermo-electric cooler or can be a hydraulic cooler and/or a gas.
The cooling and/or thermal insulating device 12, 13a, 13b also comprises a thermal insulation sleeve 12 that wraps at least part of the pipe 9. The cooling and/or thermal insulating device 12, 13a, 13b also comprises an insulating layer 5 positioned at least in correspondence of the lateral wall 3 of the container 2. In a non-limiting embodiment, the insulating layer is arranged outside of the external face of the lateral wall 3; the insulating layer 5 does not enter into contact with water 100.
The device 1 further comprises a temperature sensor configured for detecting the temperature of the water 100 present in the container 2 or that slides within the pipe 9. In a non-limiting embodiment, the temperature sensor is substantially installed in correspondence of the pipe 9, downstream of the pump 11. The temperature sensor is not described here in detail because it can be of any known technology; preferably the temperature sensor is connected with a data processing unit for allowing to adjust the intervention of the active cooler 13a, 13b in order to keep an appropriate temperature for the water 100 in such a way to have, in use, an optimal level of solubilization of the mineralizing compound.
The device 1 first of all comprises an operating configuration of mineralization, wherein the container 2 is pressurized through the gas G supplied through the gas supplying pipe 7, in order to be at first brought, and hereinafter kept, at a pressure at least equal to a predefined pressure value P1 higher than the environmental pressure (atmospheric pressure of the place where the device 1 lies). In this operating configuration, the mineralizing substance S chemically reacts in the water 100 with the gas G determining the production of a mineralizing compound of the water that is solubilized. In the operating configuration of mineralization, as it is easily understandable from the previous paragraph, and in order to bring the pressure of the container 1 to the predefined pressure value P1 higher with respect to the environmental pressure, the container 2 is positioned in a condition of substantial insulation from the external environment.
The device 1 further comprises an operating configuration of gas removal, wherein the container 2 is positioned at a pressure lower than the environmental pressure, determining a gas removal from the water 100. The air present in the container 2 is extracted through the suction pipe 15. It is observed that the operating configuration of gas removal is not necessarily present in order to ensure the functioning of the device 1. However, the actuation of said operating configuration of gas removal is useful (and preferrable) to promote a maximal dissolution of the gas G in the water.
The device 1 has been in particular conceived for allowing the solubilization of Ca in water under the form of calcium bicarbonate (Ca(HCO3)2). The gas G is, preferably, carbon dioxide (CO2). The mineralizing substance S is, preferably, calcium carbonate (CaCO3).
The gas G derives from a pressurized source, for example—but in a non-limiting extent—a bottle. Alternatively, the gas supplying pipe can be supplied by a chemical reactor conceived for the production of carbon dioxide, as main or secondary product. This reactor is not described here because of known type.
In use, during the operating configuration of mineralization, it is determined a water acidification by effect of the presence of carbon dioxide, so:
H2CO3 is carbonic acid.
Thanks to the presence of calcium carbonate (CaCO3), in the operating configuration of mineralization it is determined a chemical reaction with the carbonic acid (H2CO3) that causes the production of calcium bicarbonate (Ca(HCO3)2) that is soluble in water.
A similar chemical process is realizable through the device object of the present disclosure using magnesium carbonates, in particular magnesium bicarbonate (Mg(HCO3)2) that is produced by the following reaction starting from the milk of magnesia (or magnesium hydroxide, Mg(OH)2):
In a specific and non-limiting embodiment, the device 1 comprises a storage tank 19, operatively connected to the emptying pipe 8a and/or, if present, to the auxiliary emptying pipe 8b; in particular, the storage tank 19 is operatively connected to said pipes but is positioned downwards of the filtering system. In a preferred and non-limiting embodiment, the device 1 comprises a heating element, configured for heating the water 100 in use contained in the storage tank 19 at a temperature T2, that is preferably comprised in the range [20-60]° C., more preferably in the range [30-50]° C., or that, alternatively is comprised in the range [10-30]° C.; after the transfer in the storage tank 19, the water 100 undergoes a heating (from T1 to T2) by effect thereof the eventual carbonic acid (H2CO3) still present in the water is dissociated, and the calcium bicarbonate (Ca(HCO3)2) stabilizes.
Optionally, but preferably, a manometer can be positioned on the body of container 2 in a configuration such as to detect the pressure assumed therein.
Furthermore, always optionally, but preferably a level indicator and/or sensor can be present for allowing to verify the level assumed by the water 100 inside the container 2. The level indicator and/or sensor can be of electronic type and/or transparency type.
In
In the step of pressurization, the container 2 is clearly kept substantially insulated from the external environment.
More in detail, the block 1001 identifies the step of loading of water 100 in the container 2; the loading can occur in manual way or in automated way. The step of loading of the water is such as to leave a free height between the dispenser 6g, 6h and the water 100 itself; furthermore, the step of loading of the water is such as to submerge the G gas supply pipe.
The block 1002 identifies a step of vacuum creation (optional) in the container 2; through the suction pipe 15 a vacuum pump sucks the air from the portion of container 2 not filled with water 100, and also removes, at least partially, the gases contained within the water 100. This promotes a higher subsequent saturation with gas G (in the above-described embodiment, carbon dioxide). In an embodiment, the vacuum pump is not part of the device 1 here described. In an alternative embodiment, the vacuum pump is part of the device 1 here described.
The vacuum is kept for a predetermined time t1, for example and in a non-limiting extent equal to 1 minute, or 2 minutes or 3 minutes; after said predetermined time t1 can be present a subsequent and secondary step of aspiration of air through the suction pipe 15.
The block 1003 shows a step of supply of gas G within the container 2. Preferably, but in a non-limiting extent, the step of supply of gas G within the container 2 occurs without restoring the environmental pressure with normal air. From the vacuum, therefore, carbon dioxide (CO2) is progressively introduced into the container 2 until it reaches the predetermined pressure value P1.
Preferably, but in a non-limiting extent, P1 is at least equal to 1.5 bar, or at least equal to 2 bar, or at least equal to 3 bar. The Applicant observes that keeping a high pressure in the container 2 promotes the absorption of carbon dioxide (CO2) in the water 100. Therefore, keeping the container 2 at a pressure P1 higher with respect to the environmental pressure will promote the solubilization of calcium bicarbonate (Ca(HCO3)2).
The block 1004 identifies a step of introduction to the mineralizing substance S, that is for example—as above described—calcium carbonate (CaCO3). The introduction of the mineralizing substance S occurs through the supply input 14 of the mineralizing substance S.
The adjustment of the related amounts of water 100, of calcium carbonate (CaCO3) and of carbon dioxide (CO2) can be carried out manually or through a substantially automated control. Block 1005 identifies the step of recirculation of the water 100 contained inside the container 2; the water, that at this point starts to be saturated with CO2 is sucked from the first opening 10, enters inside the pipe 9, passes through the pump 11 and subsequently is pushed towards the second opening 6 which is at a height h1 with respect to the surface of water 100 still contained in the container and falls again downwards transiting through a height h1, in an environment under pressure and saturated with carbon dioxide. The rain generated through the holes 6h of the dispenser 6g, due to gravity force, moves along a direction substantially parallel to the direction detected by the axis X, that is in use vertically oriented and that represents the axis of the container 2.
It is observed that the step of recirculation identified by the block 1005 does not take place necessarily only at the end of the step of introduction of the mineralizing substance S; in fact, in an alternative embodiment, the step of recirculation can occur also after, or even before and during, the introduction of the mineralizing substance S.
The method object of the present disclosure comprises also a step of cooling and/or thermal heating of at least one between the container 2 and/or the water here contained. This step provides, further or alternatively to the passive thermal insulation produced through the sleeve 12 or the insulating layer 5, a step of active cooling realized through the active cooler 13a, 13b on the water that slides in the pipe 9. The temperature T1 is preferably comprised in the range [0-10]° C., more preferably comprised in the range [3-7]° C., and ideally is substantially equal to 5° C. The keeping of this temperature advantageously allows, all other conditions being equal, a greater solubilization of calcium bicarbonate (Ca(HCO3)2) in water. The method provides for an adjustment of the intervention of the active cooler 13a, 13b through a data processing unit which receives a temperature signal from the temperature sensor. It is observed that the pressurized G gas supply provides to the assembly a minimal amount of thermal energy which partially intervenes to support the endothermic dissolution process of the calcium bicarbonate (Ca(HCO3)2) in water, allowing to reduce the time needed to obtain water 100 properly provided with the appropriately solubilized mineralizing compound.
At the end of the method here described (end of the mineralization step), the water 100 can be extracted from the container 2 through the emptying pipe 8a, and/or through the auxiliary emptying pipe 8b; the water 100 results mineralized but comes out “natural” and not “gasified” as traditional drinking waters.
It is observed that optionally, the method described here can comprise a further step of treatment of water 100 extracted from container 2, which takes place at the end of the mineralization step described above.
The water 100 collected from container 2, and filtered through the filtering system 16, can advantageously be transferred into a storage tank 19; in this storage tank 19 it is preferably heated at an appropriate temperature T2, which is preferably comprised in the range [20-60]° C., more preferably in the range [30-50]° C., or that, alternatively is comprised in the range [10-30]° C.; substantially then, after the transfer in the storage tank 19, the water 100 undergoes a heating (from T1 to T2) by effect thereof the eventual carbonic acid (H2CO3) still present in the water dissociates, and the calcium bicarbonate (Ca(HCO3)2) stabilizes.
As briefly previously mentioned, the device 1 can be equipped with a data processing unit that oversees its operation, and in particular allows to switch between the operating configuration of gas removal and the operating configuration of mineralization, and optionally, allows to adjust the opening and closing of the various inlet and outlet pipes above described, so that it is possible to realize a functioning as much as possible automated of the water mineralization process above described.
The data processing unit can comprise a processor of general-purpose type, or can comprise one or more processors or dedicated integrated circuits (ASIC) or can comprise a FPGA or a PLC controller. A software program, written in any programming language, can be stored in a memory made operatively accessible by the data processing unit, e.g. contained therein, and comprises portions of software code that, when executed, cause the execution of the steps of the above-described method.
In particular the data processing unit can be operatively connected with at least one, preferably all, the solenoid valves positioned respectively on the gas supplying pipe 7, on the supply input 14 of the mineralizing substance S, on the suction pipe 15, on the emptying pipe 8a and, optionally, on the auxiliary emptying pipe 8b, and/or can be operatively connected with the pump 11 and with the active cooler 13a, 13b.
The mineralized water 100m contained within the storage tank 19 can thus be used for specific applications of a sanitary or human consumption type. In a non-limiting embodiment, the mineralized water 100m contained within the storage tank 19 can be used to realize water mineralization capsules containing a highly mineralized liquid solution to distribute (in particular uniformly diluted) in at least one water bottle and/or destined to sanitary applications.
Machine for filling a capsule for beverages and associated capsule for beverages.
The mineralized water 100m that exits from container 2, and thus when present from the storage tank, after the step of mineralization is described here as “mineralized solution”.
Before proceeding with the detailed description of the various embodiments of the machine for filling capsules, a description of some of the embodiments of the capsules for beverages 300, which are in particular conceived to be filled with a mineralized solution produced through the above-described device, is provided.
Although reference is made in the present disclosure to a machine conceived with the purpose of filling one capsule for beverages 300 at a time, it is understood that this solution is not to be understood in a limiting manner; in fact, in an embodiment, the machine described herein can be configured for operating with more capsules for beverages 300, and in particular can be configured for operating a simultaneous loading of at least part of a plurality of capsules for beverages 300.
The capsule for beverages 300 comprises a body provided with a head portion 300t and a lateral wall that comprises a bottom portion 301 opposed with respect to the head portion 302. The head portion 302 has a head wall 300t which is parallel to the wall of the bottom portion. Clearly this geometric conformation is not to be understood as limiting.
The head portion 302 preferably is tapered with respect to the remaining portion of the body of the capsule for beverages 300; this means that the capsule for beverages 300 has a first portion having a first (and greater) cross section and a second portion, in particular the head portion 302, having a second (and smaller) cross section. In an embodiment, the body of the capsule is cylindrical and therefore the aforementioned cross sections can be identified through a respective diameter. In particular, then, the cavity 300c of the capsule for beverages comprises a first portion having a first cross section, and this first portion can be understood as the central or main portion. The cavity 300c in correspondence of the head portion 302 assumes a second cross section: the latter is of lower value than the cross section of the first portion.
In a non-limiting embodiment, the capsule for beverages 300 is assembled and can be operatively disjoined into two distinct portions. A specific embodiment provides for the demountable bottom portion 301, in particular unscrewable, with respect to the rest of the body of the capsule.
The capsule for beverages 300 can be realized in any material, in particular in any material compatible with food applications or for sanitary purposes. In an embodiment, this material is a metallic material, e.g. aluminium, steel or brass. This also makes the capsule reusable. In a non-limiting embodiment, the capsule for beverages 300 object of the present disclosure is realized in a material resistant to carbon dioxide, in particular a material configured for not chemically reacting with the carbon dioxide present in use in the cavity 300c, in order not to affect its content.
The capsule for beverages 300 comprises an orifice 306 that allows the passage of gas and/or fluids, in particular of the mineralized solution, from the inner cavity 300c of the capsule for beverages 300, outside of the capsule for beverages 300 and vice versa. In a preferred and non-limiting embodiment, the orifice 306 is positioned in substantial correspondence of the head portion 302, ed in particular in correspondence of the head wall 300t. In the embodiment shown in the attached figures, the orifice 306 has an its own axis that is substantially parallel to the direction of maximum extension of the capsule for beverages 300, and in particular is substantially coincident with the direction of maximum extension of the capsule for beverages 300. Preferably, the orifice 306 has a cross section (orthogonal with respect to its axis) of substantially circular shape.
Inside the cavity 300c there is a seal 305, movable at least between a first position suitable for determining a closure of the orifice 306 and a second position suitable for determining the opening of the orifice 306 and thus of the capsule for beverages 300; in an embodiment the movable seal 305 is movable in an axial direction. In particular, in
The attached figures show embodiments wherein the seal 305 assumes a substantially discoidal or otherwise planar shape. However, this shape is not to be understood as limiting; in an alternative embodiment the seal 305 assumes the shape of an anti-flooding valve with multiple and movable elements.

In a not shown embodiment, the seal 305 is configured for moving with a composite roto-translational movement that takes place between the first position and the second position.
Preferably, as shown in
The capsule for beverages 300 is configured for keeping, in rest conditions, the seal 305 in said first position; equivalently, the capsule for beverages 300 is configured for keeping, in rest conditions, the orifice 306 in closed configuration. In this way, the pressure contained within the cavity 300c is favorably kept. The seal 305 is moved from its resting condition only by effect of an external force which causes a switch of operating configuration for the capsule for beverages 300, in particular between a closed or sealed operating configuration wherein the cavity 300c is insulated and an open operating configuration wherein the cavity 300c is accessible from the outside of the capsule for beverages 300.
When the seal 305 is moved from the first position toward the second position, the pressurization within the cavity 300c can be released; where the pressure of the external environment is greater with respect to the one of the cavity 300c, the movement of the seal 305 from the first position towards the second position determines the possibility of pressure increase for the cavity 300c.
In use the capsule for beverages 300 contains preferably a mineralizing solution mixed with a gas, e.g. carbon dioxide, and when the seal 305 is moved from the first position, the presence of said gas conveniently allows a substantially total extraction of the mineralizing solution here contained.
The seal 305 can be moved between the first and the second position a plurality of times, without breaking. Thanks to this aspect, it is possible to proceed to an extraction of the content of the capsule for beverages 300 in subsequent time instants.
For this purpose, an elastic element 304, for example and in a non-limiting extent, in the shape of a spring (e.g. an helical spring), is arranged within the capsule for beverages 300 in order to allow the exertion of a force which determines, in said rest conditions, the maintenance of the seal 305 in said first position.
In the embodiment shown in
In an alternative, not shown, embodiment, the elastic element 304 can be partially integrated in the seal 305.
Preferably, but in a non-limiting extent, the seal 305 is a flexible seal, and in a specific embodiment is realized in polymeric material, in particular silicone. Specifically, such silicone is destined for applications compatible with human consumption. The use of a flexible seal allows it to adapt to micro asperities that may be found in correspondence of the striking wall, determining an optimal closing of it. In particular, the seal 305 can assume a substantially shaped disc in silicone.
When the capsule for beverages 300 is operatively demountable, the seal 305 and/or the elastic element 304 can be replaced. This contributes to allow the creation of a reusable capsule for beverages.
In a non-limiting embodiment, the capsule for beverages 300 comprises a connector engageable on a predetermined portion of a machine for filling capsules; the connector, which for example and non-limiting thereto can be either a bayonet connector or a screwable connector, is preferably positioned in substantial correspondence of the head portion 302.
Preferably, but in a non-limiting extent, the capsule for beverages 300, and in particular the seal 305, are configured to support, in use, a pressure higher with respect to the operating pressure that is typical of the previously described device; in a preferred, but non-limiting embodiment, the capsule for beverages 300 and in particular the seal 305 are configured for supporting, in use, a pressure at least equal to 4 bar. If this is not possible, it is still preferable, for safety reasons, that the capsule for beverages 300 and the seal 305 are configured to withstand at least a pressure of 2 bar or 3 bar.
The machine for filling capsules here described comprises an injection system 201, 400, 401, 402 configured for operatively coupling with said capsules for beverages 300 and for supplying in pressurized manner, in use, a gas and/or a fluid solution, in particular said mineralized solution, into the capsule for beverages 300.
The machine described here comprises a seat 200, 200′ configured for housing at least one capsule for beverages 300 to fill with a gas and/or with a fluid solution, in particular with a mineralized solution.
In
The machine for filling capsules, in a first embodiment shown in
The chamber 200 shows at least an open configuration and a closed configuration; in the open configuration, the chamber is configured for allowing the entry of the capsule for beverages 300; in the closed configuration, the cavity 300c is sealed and is ready to be brought to a pressure greater with respect to the environmental pressure. When the machine is configured for operating with more capsules for beverages 300, this machine will be provided with a chamber 200 capable of containing a plurality of said capsules for beverages 300, or will be provided with more chambers 200 capable of containing, each, at least one capsule for beverages 300.
The chamber 200 comprises at least an openable and closable cover; in a closed configuration, the chamber 200 is insulated from the external environment. In a non-limiting embodiment, the cover is configured for rotating between an open position and a closed position, whereas in another embodiment the cover is configured for translating between the open position and the closed position. In a further embodiment, the cover is configured for performing a complex roto-translational movement.
An opening for the access of gases and/or fluids 201, part of the injection system 201, 400, 401, 402, is present in correspondence of the chamber 200 for allowing its pressurization or depressurization. A gas and/or fluid (in particular the mineralized solution) are supplied within the chamber 200 when the cover is closed, determining, in use, a pressurization thereof.
Within the chamber 200 there is a pin 402, also part of the injection system 201, 400, 401, 402; the pin 402 is movable at least between a first position and a second position; in the first position the pin 402 is spaced from the capsule for beverages 300; in the second position the pin 402 is partially introduced within the capsule for beverages 300, in particular resulting introduced within an orifice 306 present in substantial correspondence of the head portion of the capsule for beverages 300. Therefore during a process of loading of the capsule for beverages 300 there is a step of movement of pin 402 between the first position and the second position.
In a preferred but non-limiting embodiment, the pin 402 is axially oriented on the Y axis of the orifice 306 and in use translates along this axis. The cross section S1 of the pin is smaller than the cross section of the orifice 306. Thus, when the pin is introduced into the orifice 306 (second position) a free area is present between the pin and the walls of the orifice. This free area allows the passage of the mineralized solution or of a gas (e.g. carbon dioxide or air) into the capsule for beverages 300. Thus in a non-limiting embodiment, the step of movement of the pin 402 is a step of translation, in particular of axial translation.
A retaining block 202 is present within the chamber 200 for retaining the capsule for beverages 300 in an appropriate and predetermined position that allows the introduction of the pin into the orifice 306. In a preferred but non-limiting embodiment, the striker 202 is positioned in substantial correspondence of the rear portion of the capsule for beverages 300. The striker 202 can be present also within the chamber 200 and is preferably configured for geometrically coupling with a portion of the capsule for beverages 300, in particular and non-limiting thereto the bottom portion 301. Preferably, but non-limiting thereto, the striker 202 is elastic, and when the capsule for beverages 300 is coupled thereto, it keeps a slightly deformed configuration, which loses when the capsule for beverages 300 is extracted.
In an embodiment this retaining block 202 can be configured for retaining at least part of the body of the capsule in correspondence of the bottom portion 301 and of a portion of lateral surface next to the bottom portion 301.
Preferably, although in a non-limiting extent, the retaining block 202 can be movable between a first rest position and a second unstable position, the latter being kept when the capsule for beverages 300 is introduced into the seat. A spring, not shown in the attached figures, can be used to force the striker 202 into the first rest position. Alternatively to the spring, a servo-actuator, for example controlled by a data processing unit of the machine described herein, can be equivalently used to move the striker 202 between said first and said second position. In the latter case, the first rest position and the second position may not be unstable.
In another embodiment, the movement of the cover determines a movement of the retaining block 202 in the following manner: when the cover is open the retaining block 202 is in the second position and the capsule for beverages 300 can be easily introduced in the seat, in particular in the chamber 200. When the cover is closed the retaining block 202 is in the first position and the capsule for beverages 300 is blocked in a predetermined position that aids the operation of the pin 402. It is observed that the mobility of the retaining block 202 is a technical characteristic that can be present even if the seat 200, 200′ assumes the shape of a substantially open seat.
In use, the pin 402, through its movement from the first to the second position, determines an opening of the orifice 306 forcing, by contact, a movement of the seal 305 between the first position and the second position. The pressurized gas present within the chamber 200 enters the capsule for beverages 300. The thrust exerted by the pin 402 determines a translation and/or a rotation of the seal 305; the elastic element 304 is progressively compressed.
The machine for filling capsules is also configured for allowing to introduce the mineralized solution into the capsule for beverages 300 while keeping it under pressure thanks to the presence of the pressurized gas present within the chamber 200.
In an embodiment, the chamber 200 is partially filled with said mineralized solution and upon the movement of the seal 305 from the second position to the first position through the pin, this mineralized solution enters the capsule for beverages 300 through the orifice 306 together with part of the gas.
The Applicant has conceived another embodiment, wherein the chamber 200 is not provided with the pin. In this case, the pressure in use developed inside the chamber 200 itself is sufficient to determine a movement of the seal 305 from the first to the second position to determine a supply of the mineralized solution and/or of the gas inside the capsule, determining an at least partial filling.
In an operating configuration of filling of the at least one capsule for beverages 300, the chamber 200 is pressurized; in an operating configuration of introduction and/or extraction of the at least one capsule for beverages 300, the chamber 200 is not pressurized.
In an alternative embodiment, the filling element 400 assumes a shape of an injector that comprises:
The element 400, also in this last embodiment, can be positioned in a second position wherein it is in substantial contact with the head portion 302 of the capsule for beverages 300. In the second position, in particular, and as shown in
In general it can therefore be asserted that the machine here described is configured for causing a relative movement, in particular a relative axial translation, between the capsule for beverages 300 and the element 400 at least between:
Depending on the specific embodiment, when the second position exists relatively assumed between the element 400 and the capsule for beverages 300:
In a non-limiting embodiment, a contact portion of the injection or filling pipe 401 (front portion, in use in contact with the head wall 300t) can be realized in soft and/or yielding material, e.g. a polymeric material comprising a silicone, to realize in use an optimal contact.
In an embodiment, when the injection or filling pipe 401 is placed in contact with the capsule for beverages 300 (second position relatively assumed between them), the mineralized solution is made flow in the injection or filling pipe 401.
In another embodiment, the capsule for beverages 300 is previously filled with said mineralized solution, and in use, when the injection or filling pipe 401 is placed in contact with the capsule for beverages 300 (second position relatively assumed between them), a gas is made flow into the injection or filling pipe 401.
Another embodiment of the machine for filling capsules provides for a seat 200′ of retention of capsules for beverages 300, provided with a striker 202 for the capsule for beverages 300, and a striking flange 204, that in use enters into substantial contact with the capsule for beverages 300 in correspondence of the head portion 302. In this last case, the presence of a chamber 200 in use pressurized is not necessary.
An element 400 comprising an injection or filling pipe 401 configured for allowing the introduction of gas and/or of the mineralized solution within the capsule for beverages 300 is fixed to the striking flange 204. The striking flange 204 houses in its interior at least part of the injection or filling pipe 401, and as visible in
The element 400 comprising an injection or filling pipe 401 is placed in contact with the capsule for beverages 300 so that between the injection or filling pipe 401 and the capsule for beverages 300, or between the striking flange 204 and the capsule for beverages 300 a seal is maintained so as to allow the introduction of gas and/or of the mineralized solution under pressure without significant leakages.
A contact area A between the striking flange 204 and an undercut present in correspondence of said neck ensures a sufficient seal to allow the introduction of gas and/or of the mineralized solution into the capsule for beverages 300 without substantial leakages.
In particular, it is observed that in
When the capsule for beverages 300 and the injection or filling pipe 401 or the capsule for beverages 300 and the striking flange 204 are properly brought into contact in correspondence of the reciprocal contact areas A, a gas or mineralized solution flow is started so as to cause an appropriate filling of the capsule for beverages.
In a non-limiting embodiment, the gas used for the filling of the capsule for beverages 300 is said mineral solubilization gas G, and in particular is carbon dioxide (CO2). Thanks to this aspect, the mineralized solution is preserved.
When the gas or mineralized solution flow is interrupted or the pressure exerted by them in the injection or filling pipe 401 descends under the pressure assumed within the capsule for beverages 300, by effect of the elastic element 304 the seal 305 assumes again the first position, and the capsule for beverages 300 results insulated from the external environment and provided with a properly pressurized mineralized solution. The orifice 306 is closed.
The capsule for beverages 300 can be emptied with a pin similar to the pin 402 previously described.
Where the capsule for beverages 300 is provided with said connector, preferably also the machine here described will be provided with a connector configured for allowing a removable coupling, in particular a locking, of the capsule for beverages 300 in correspondence of said seat 200, 200′. In a non-limiting embodiment, the connector of the machine can in particular be installed in substantial correspondence of the striking flange 204.
It is finally observed that the device 1 for the water treatment and the machine here described can be integrated in a unique apparatus or be operatively connected the one with the other. When operatively connected the one with the other, the apparatus results capable of realizing mixtures highly enriched with properly solubilized minerals and results capable of supplying capsules for beverages 300 opportunely loaded with strongly mineralized mixtures whose minerals are properly solubilized.
It is observed that the invention is not limited to the attached embodiments; for this reason, in the following claims, the numbers and reference signs positioned between parentheses are supplied with the sole purpose of increasing the intelligibility of claims, and must not be considered as limiting.
It is finally clear that to the object of the present invention can be applied additions, modifications or variants, obvious for an expert in the art, without departing for this reason from the scope of protection provided by the annexed claims.
