DESCRIPTION

Procedure and apparatus for manufacturing a capsule of a beverage. Invention Sector

The present invention relates, in a general way, to a process for the manufacture of a capsule of a beverage for use in a beverage making machine. This also refers also to an apparatus for carrying out said procedure, as well as the beverage capsules produced in this way. In a particular way, the present invention relates to such types of capsules for coffee drinks.

Background and background of the invention

It is known, in the specialized art of the art, to pack perishable food products, in sealed containers or containers. This technique excludes the air and moisture from the unopened container, thus improving the shelf life and taste of the products inside. This procedure is especially advantageous for the packaging of roasted coffee (roasted coffee).

The roasting or roasting process is what produces the characteristic flavor of coffee, causing the fact that green coffee beans expand and change in terms of color, aroma and density. The volatile oils and aromatics contained and / or developed during the roasting or roasting process, confer the aroma and flavor of the coffee drink produced from them, but these are also prone to degradation, when they are exposed to oxygen , in the surrounding air. The packaged coffee, in sealed containers, will protect it from the surrounding air, resulting in a longer shelf life and optimum flavor and aroma, during consumption.

Recently, it has been usual to proceed to package coffee and other ingredients of beverages of this type, in capsules for a single service, adapted for use in a beverage system, by which an Individual drink is prepared, upon request, to from this type of capsules. The capsules in question, contain a predoslflcada amount of an Ingredient of or several ingredients of a drink, in the form of edible granules, finely textured. Such types of beverage capsules can be sealed in an airtight manner, thus preventing or preventing the degradation of the ingredient or ingredients of the beverage, prior to consumption.

While this patent application document refers primarily to beverage capsules, which contain roasted or roasted coffee, it will also be understood that, in such types of capsules, they can also be used, likewise, other food substances. By way of non-limiting example, such types of edible granules may comprise roasted or roasted coffee, ground coffee, soluble coffee, powdered milk, cocoa powder, loose tea leaves, and / or other herbs, broth, or any combination of between these.

In order to proceed to prepare the beverage, the beverage capsule is located in the beverage production machine, this machine, which introduces hot water into the beverage capsule, and dispenses the resulting beverage, by inside a container, for consumption. While, in this patent application document reference is made to a "capsule", it will be understood nevertheless the fact that, instead of this term, reference may also be made, also, to other terms, such as those consisting of "pod", "cartridge", or "envelope".

In order to offer additional protection of the edible granules, against degradation, prior to consumption, it is also known, also, that of beverage capsules, under a modified atmosphere (such as, for example, an atmosphere saturated with nitrogen or with carbon dioxide), or under the action of vacuum. In a particular way, vacuum can be applied to the capsule, when the capsule in question is filled with a beverage ingredient, to remove the air inside. The beverage capsule is formed based on gas-tight and hermetically sealed packaging materials, in order to preserve the vacuum inside. Thus, in this way, any oxygen which is present in the capsule is removed, prior to sealing, and the edible granules are thus protected from degradation, prior to proceeding with their consumption.

However, however, the sealing of a beverage capsule, by vacuum sealing, introduces additional complications. Since, the edible granules, in a general way, are of a small size, and of a slight size, the application of the vacuum can suck them out of the capsule. Such types of edible granules can be aspirated into the vacuum application medium, causing damage to the vacuum, thereby increasing the maintenance costs of the vacuum sealing apparatus.

The edible granules can also be dragged between the sealing walls of the capsule, such as, for example, between the body and the sealing means of the capsule, preventing and preventing the latter from joining with the first, adhering to this one. This fact compromises the strength and aesthetic quality of the sealing of the

beverage capsule, and therefore, the protection of edible granules in the field of sealing the beverage capsule.

The drag of the edible granules may also result in tearing of the seal of the beverage capsule, due to the increase in pressure, inside the capsule, during the beverage preparation process. This fact may also result in the rupture of the capsule, and the release of wet coffee powder, through the torn or broken seal, thus soiling the beverage machine, and producing a beverage. Of disgusting flavor.

The sealing of the beverage capsule, under the action of the vacuum, which contains ground coffee, is already known in the specialized art of the art, being able to cite, for that purpose, US Patent US 5 472. 719 and likewise , also, European patent EP 1 866 942, in which reference is made to these. The latter document discloses a beverage capsule, which contains an amount of coffee, which has been expressed in a tablet, reducing the size of the capsule and obviating the need for a filter inside. A vacuum is created, in the Interior of the capsule, and the capsule in question, is sealed, by means of a flexible cover, thus preventing degradation of the coffee tablet which is inside.

International Patent WO 2008 129 350, refers to a machine for packaging capsules, also, also under the action of vacuum and / or in a controlled atmosphere. After filling with coffee, the capsules are partially closed by an airtight film. Then, a vacuum is formed inside the capsules, and these are sealed, by a vacuum heat sealing device.

US Patent U S 3 775 932, refers to a packaging apparatus, for the preparation of vacuum packaging, of a product, by sealing superimposed films, together with the product contained therein. The vacuum is produced by aspiration, by connecting a vacuum tube, in the partially sealed container, where the edge of the packaging film is captured between the sealing head and the flexible strip, leaving the edge free of the superimposed film.

US patent U S 2010 0 076 633, refers to a machine for packaging product, in a particular way, for packaging capsules, for beverage dispensing machines consisting of infusions. A vacuum bell provides the vacuum around each of the capsules to be welded. At the same time, a means of vacuum compensation, takes care of the insertion gas, this consisting, in a particular way, of nitrogen, inside each capsule, so that the presence of vacuum is compensated. After that, the welding means takes care of the welding of the aluminum sheet, on the edge of the respective capsule.

US Patent U S 4 069 349, refers to a process for vacuum packaging of roasted coffee (ground coffee), in sachets or sachets. The bags or sachets in question are partially sealed, leaving a tortuous fragment or unsealed passage, and then stored for a predetermined course of time, to allow gases to develop from the sacks or sachets, and then sealing the bags or sachets in question, to avoid gaseous steps towards the product, or from the product.

However, however, these references corresponding to the prior art of the specialized technique do not solve the problem of aspiration and entrainment of the edible granules.

It is therefore an object of the present invention to provide a process for the manufacture of beverage capsules, in which the edible granules can be sealed, under the action of vacuum, inside a beverage capsule, by at the same time that the aspiration of such types of edible granules is reduced or eliminated, and thereby producing a seal of high integrity.

Correspondingly in accordance, in a first aspect of the present invention, therefore, this refers to a process for the manufacture of a beverage capsule, in accordance with the distinctive features and features of claim 7 of that patent application document.

The joining of the second member of the second wall member, to the flange or flange of the first wall member, along at least two regions, avoids the fact that the second wall member moves in any direction, along the flange or flange, when the vacuum is applied. This fact is advantageous, due to the fact that, the joining of the second wall member, to at least two regions of the flange or flange in question, of the first wall member, reduces or eliminates the aspiration of the edible granules, during The application of the vacuum. This also avoids the fact that the second wall member is moved, (such as, for example, moving and taking advantage of the center), that it deforms, or that it bends or folds , prior to the second sealing stage, thus avoiding the formation of wrinkles, folds or creases, or in other undesirable ways, in the second wall member. As a result of the above, it is possible to proceed to produce capsules, more quickly, in the production line, while ensuring quality, through a high level of vacuum.

According to a particular form of presentation, in accordance with the present invention, the wall member is attached to said flange or flange, in a plurality of regions of said flange or flange, thereby dividing the flange or flange in question, in a circumferential way, in a plurality of joined regions; and proceeding to apply, the vacuum, between said first wall member and second wall member, thereby evacuating the gas, from the interior of said cavity, and from said edible granules, through said plurality of unbound regions of the flange or flange, thereby creating a void in said cavity.

The term "plurality," as used in the present context, means one (or one), or more than one (or more than one).

This is advantageous, due to the fact that the joining of the second wall member, to a plurality of flange or flange regions, of the first wall member, will reduce or eliminate the aspiration of edible granules, during vacuum application. In a particular way, the joined regions avoid the fact that the edible granules leave the capsule. However, however, the gas in the cavity and the edible granules can still be removed, as it still flows through the spaces between the flange and the second wall member, in the unbound regions .

Thus, since, the edible granules can be confined in the first wall member, during vacuum application, the amount of such types of edible granules, which are sucked into the sealing apparatus into the empty, it is greatly reduced. The amount of damage that the edible granules cause in the sealing and vacuum means of the apparatus, and the consequent maintenance and repair costs, are reduced or even eliminated. The execution of this procedure thus becomes more effective in terms of costs, and more reliable, while, simultaneously, the quality of the capsules of this beverage is improved. produced form.

The drag of the edible granules, between the second wall member and the flange or flange of the first wall member, in a similar manner, is reduced, or even eliminated. Since the edible granules no longer interfere with the interface or interrelation between the wall members, then the fact is that they improve the strength and aesthetic quality of the seal between the two. The physical properties of the beverage capsule are thus optimized, thus providing more effective protection to edible granules, and better preservation of the flavor and aroma of the beverage produced from it.

Finally, the procedure in question allows the aforementioned advantages, above, to be carried out, while providing the vacuum and sealing of the beverage capsules, individually. The attachment of the second wall member to the flange or flange of the first wall member, prior to the application of a vacuum, and the sealing of the beverage capsule, allow the fact that the vacuum can be quickly applied, while still It maintains a high level of resistance and aesthetic quality, in sealed beverage capsules. Since, the vacuum is applied only to the beverage capsules, one by one, individually, the sealing of each beverage capsule can be monitored and controlled, individually. The sealing process can thus become a process that can be adapted, so that each capsule is provided with a seal of the highest possible quality. Thus, in this way, the efficiency of the procedure is maximized, while, in a simultaneous manner, the fact is ensured that the beverage capsules manufactured in this way are of the highest possible quality.

According to another particular form of presentation, in accordance with the present invention, the method is characterized by the fact that the first wall member is a self-supporting capsule body, and said second wall member is a flexible membrane. .

This form of presentation, in accordance with the present invention, is advantageous, due to the fact that the first and second wall members, in the form of a self-supporting capsule body, and a flexible membrane, facilitate the provision of coffee, in the inside of the capsule body, and the sealing of the membrane, on the flange. Likewise, also, a self-supporting capsule body, will provide a structural strength or strength to the non-sealed beverage capsule, thus facilitating, in this way, handling, during the manufacturing process. The advantages of the present invention can be carried out by a minimum effort and costs.

According to another particular form of presentation, in accordance with the present invention, the steps for joining and sealing the second wall member, on said flange or flange, are carried out by a heat sealing process.

This is advantageous, due to the fact that heat sealing processes can quickly produce seals, which are, in general, air tight, durable, flexible and hygienic. The heat sealing means may also be integrated into an apparatus, which embodies and represents this procedure, such as by incorporating hot air jets, electric heater heaters, or the like. Heat sealing processes can also be adapted to work with a variety of materials, thereby improving the compatibility of this procedure.

In addition, the links created between the second wall member and the flange of the first wall member, during the joining stage, will be substantially identical to the seal created during the sealing stage. This results in a seal, which is uniform, across its entire surface, without any area of diminished strength or strength, or other undesirable variations. Additionally, this form of presentation, in accordance with the present invention, is advantageous, due to the fact that the first and the second wall members need to be appropriate for only a single type of joining process, instead of two types, thereby increasing the selection of possible materials, for the components of the beverage capsule. Thus, therefore, this form of presentation, in accordance with the present invention, makes the present invention more simple and simple to practice, while producing improved results.

In a possible alternative, in accordance with the present invention, the joining and sealing stages of said second member, on said flange or flange, are carried out by means of an ultrasonic welding process.

This is advantageous, due to the fact that, as in the case of heat sealing, ultrasonic sealing can produce, quickly sealed, which, in a general way, are air tight, durable, flexible , and hygienic. Ultrasonic welding is also advantageous, also, due to the fact that it does not require the fact that the first and second wall members must be heated, in order to create a seal, thus allowing this way, that these components are manufactured from materials, which may not be appropriate for the heat sealing process. Thus, in this way, the versatility of the invention is improved.

According to yet another particular form of presentation, in accordance with the present invention, the second wall member is attached to said flange or flange, over an area, which comprises a percentage comprised within 25% margins and 90%, preferably within a range between 30% and 75%, of the total sealed surface of said flange or flange of the first wall member.

This fact is advantageous, due to the fact that, the joining of the second wall member, to the flange or flange, in the ranges provided above, allow the vacuum to be applied, by means of a maximum speed and a minimum aspiration of the edible granules, inside the beverage capsule. As a result of the foregoing, the efficiency and effectiveness of the cost of the procedure are improved.

According to yet another particular form of presentation, in accordance with the present invention, the edible granules are provided in the cavity, in a loose manner.

This is advantageous, due to the fact that, by providing the edible granules in this way, the need for compacting the edible granules, inside the beverage capsule, is eliminated. Instead, the edible granules are simply inserted inside the cavity, and sealed inside, without the need to require any time for compaction, or an additional device, to carry out the process. Thus, in this way, the process becomes faster, more efficient, and more economical.

According to yet another particular form of presentation, in accordance with the present invention, the application of the vacuum and the sealing, while maintaining the vacuum inside the cavity, are carried out, immediately after the union of the second wall member, to the flange or flange, and dividing the flange or flange, into at least two or a plurality of joined and unbound regions. By the term "immediately", it is intended to imply the fact that there is no pause, which exceeds a period of time of a few seconds, which allows the fact that the edible granules lose gas from a Significant form, and therefore, aroma.

This fact is advantageous, due to the fact that, the beverage capsule of this manufactured form will represent the advantages of the present invention, in the manner which has been detailed above, above.

The joining means, 100, is configured in such a way that, this, a membrane 112, to the flange or flange, 109, on the regions where, the faces or surfaces of the lower end, 113, press the mentioned membrane, 112, into the flange or flange, 109, of the capsule body, 103. In the present form of presentation, in accordance with the present invention, the attachment of the membrane 112, to the flange or flange 109, of the capsule body, 103, is carried out by heat welding; although, however, in other forms of presentation, in accordance with the present invention, alternative techniques may be preferred, such as those consisting of ultrasonic welding.

The joining means, 100, is provided, for that purpose, with an appropriate means for attaching the membrane 112, to the flange or flange, 109, during the joining stage. Thus, for example, such types of means may comprise an electric resistance heater, a hot air jet, or an ultrasonic welding furnace. This will make the device more compact and efficient in terms of the space it occupies.

Said regions of the flange or flange 109, corresponding to the faces or surfaces of the lower end, 113, of the joining means, 100, will comprise a portion of the total surface of the flange or flange 109. The cavity 106 of the valve body, 103, thus, thus remains in communication with the surrounding atmosphere, via the spaces located between the flange or flange 109, and the membrane 112, where the membrane 112 in question remains non-unit to the flange or flange 109.

View D represents the apparatus, in a fourth position, after the joining stage has been completed. The joining means, 100, and the cutting means, 101, are removed from the capsule body, 103, and the membrane 112. The remains of the membrane material, 110, must be removed, while the base plate, 104, it is advanced, in direction 114, for both things, to place the beverage capsule, putting it in position, for vacuum sealing, and to take the next beverage capsule, to the position for the joining and cut.

Preferably, the stage for the cutting of the membrane 112, in the manner in which it is represented in view B, and the stage for the joining of said membrane 112, to the flange or flange, 109, such and as this is represented in view C, they are carried out in a sequential manner, but, in a continuous movement of descent of the cutting and joining means, 101, 100. It also proceeds, also, to apply a slight vacuum, by means of the joining means, to keep the membrane 112 in a coaxial position, on the axis 102, during the cutting and joining stages. This is advantageous, due to the fact that the time for manufacturing a capsule is minimized, and thus, the production rate at which the capsules are produced is increased.

View E represents the apparatus, in a fifth position, prior to the start of a sealing stage. The cutting and joining means which have been represented in the previous stages, are omitted here, in this case, for the purposes of clarity; although, however, however, the cutting and joining means are arranged, ideally, in an adjoining manner, or in close proximity with respect to the means of application of the vacuum, 115, and the means sealing, 116, thus making the device in question more compact, and more efficient, as regards the space required.

In a preferred form of presentation, in accordance with the present invention, the means of application of the vacuum, 115, and the sealing means, 116 are, preferably, of a tubular shape, and these are arranged in a way coaxial, around the second longitudinal axis, 117. The sealing means, 116, is configured in the form of a hollow cylinder, of approximately the width and the same diameter, as those corresponding to the flange or flange 109 of the beverage capsule , 103. The means for applying the vacuum, 115, is also configured, also, in the form of a hollow cylinder, and this is provided with a means for creating the vacuum inside. Preferably, the means of application of the vacuum, 115, in question, is configured so that it is capable of performing a translational movement, relative to the sealing means, 116, along the second longitudinal axis , 117.

The base plate, 104, is advanced in the direction 114, until, the capsule body, 103, and the membrane 112, are also coaxial, with respect to the means of application of the vacuum, 115, and the sealing means, 116, around the second longitudinal axis, 117. The capsule body, 103, and the membrane 112, are thus positioned in a central position, directly below the means of application of the vacuum, 115, and the sealing means, 116.

The view F represents the apparatus, in a sixth position, during the vacuum application stage. The vacuum application means 115 has been advanced so that an air tight seal is created between the mouth 118 of the vacuum application means 115 and the flange 109 of the capsule body , 103. A vacuum, 119, is applied to the capsule body, 103, by means of the vacuum application means, 115, thereby reducing the pressure, in the cavity 106 of the capsule body, 103, at a value that is below that of atmospheric pressure.

The vacuum 119 causes the fact that the gas existing in the cavity 106 of the capsule body 103 is extracted outwardly, by means of a plurality of spaces existing between the flange 109 and the membrane 112, which are located defined by the regions, wherein said membrane 112 remains not

attached to said flange or flange, 109. The gas can be air, or any type of inert gas, such as that consisting of nitrogen, in C02, or in any combination of these. Thus, in this way, the cavity 106 of the capsule body, 107, is emptied of gas, and a vacuum is created inside.

The vacuum application stage is preferably configured so that the vacuum can be applied quickly to the capsule body 103, while avoiding the suction of coffee powder, 107 , from cavity 106. It is known that the rapid application of vacuum to a beverage capsule can cause the fact that a certain amount of coffee inside is sucked out, which could result in a damaged device, caused by the coffee powder sucked. The coffee powder in question can also be dragged between the sealing surfaces of the beverage capsule, thus weakening, in this way, the sealing in question, and decreasing the aesthetic properties. The application of the vacuum can also cause the fact that the sealing means moves, thereby compressing the sealing integrity in an additional manner.

Here, in this case, the joining of the membrane 112 of the flange or flange, 109, of the capsule body 103, over a plurality of regions, will prevent the aspiration and drag of the coffee powder, 107, between the flange or flange , 109, and the membrane 112, as well as preventing the displacement of the membrane, relative to the capsule body, during the application of the vacuum, 119. The integrity of the sealing of the beverage capsule and the reliability of the sealing apparatus, they are thus preserved, in this way, even when the vacuum is applied very quickly, thus allowing a higher quality of the beverage capsules to be produced, at a faster rate.

The stage of application of the vacuum is also configured, so that it allows the conditions existing inside the capsule to be controlled, as the vacuum is applied, 119. In a specific way, the means of application of the vacuum in question, allows the rapid application of the vacuum, 119, to a capsule body 103, individually, instead of a slower application of a vacuum, to a group of capsule bodies, in a chamber of empty. Thus, through the use of a collection of data and / or control procedures, which are known in the specialized art of the art, a person skilled in said specialized art of the technique, can adapt, in a way Continuous, the parameters of the vacuum sealing process, in order to optimize the sealing of each capsule, while still maintaining a high production rate.

The view G represents the apparatus, in a seventh position, during a sealing stage. The mouth 118 of the vacuum application means, 115, is kept in contact with the flange or flange, 109, of the capsule body, 103, so that the vacuum is maintained inside the cavity 106 of the capsule body , 103.

The sealing means 116 is preferably provided with a means for creating a seal between the membrane 119 and the flange 109 of the capsule body 103, in a manner similar to the joining means which has been discussed above, above. As in the case of the joining means, this may comprise means such as those consisting of a heater by means of an electric resistor, hot air jets, or an ultrasonic welding furnace.

The sealing means, 116, is advanced, putting it in contact with the membrane 112, proceeding to press it along the sealing edge, 120, which is arranged at one end of said sealing means, 116. The membrane 112, is pressed into the flange or flange, 109, by means of the sealing means, 116, thereby joining the remaining regions not attached to the membrane 112, to the surface of the flange or flange, 109, and sealing the cavity 106 of the capsule body, 103. While the remaining non-membrane unit regions are joined, the union of the joined regions can be renewed. The hermetic, air-tight seal, created between the flange or flange, 109, and the membrane 112, will thus keep the vacuum in the cavity 106 of the capsule body 103, thus protecting, in this way, that the coffee powder, 107, is exposed to the air and the subsequent loss of flavor and aroma.

View H represents the beverage capsule, sealed, after the sealing stage has been completed. The sealing means, 116, is removed, in order to allow the joint to solidify. Then, the vacuum is stopped in the vacuum medium, thus exposing the capsule body 103 and the membrane 112 to atmospheric pressure and causing the fact that the membrane 112, acquire a concave shape, of the form which is represented in the figure. Finally, the vacuum application means, 115 is removed. The vacuum which is applied to the capsule body, 103, at an early stage, is kept inside, by sealing between the flange or flange, 109, and the membrane 112. The base plate, 104, moves outward, then in the 114th direction, removing the capsule to be packaged, and distributed, and bringing the next capsule into position, for vacuum sealing.

In an additional way to the benefits which are provided by the present invention, and which have been discussed above, above, there is also an additional benefit, when, as is the case in this form of presentation, in In accordance with the present invention, the edible granules are of a substance, which tends to develop gas. Such types of substances, notably, include coffee

roasted (roasted coffee), in a special way, to roasted, powdered coffee, in the manner described above, in this patent application document.

As a result of the chemical process which is triggered by the roasting or roasting process, the coffee powder, 107, will develop gas, during a certain period of time, after the roasting or roasting process has been completed, this process , which is known, in the specialized art of the technique, as a process of "degassing". As the coffee powder is degassed, 107, inside the beverage capsule, the gases which have been developed, are maintained in the cavity 106, of the beverage capsule, by means of the membrane, 112, the body of capsule, 103, and the hermetic seal existing between them.

This accumulation of the developed gases will cause the fact that the pressure inside the beverage capsule is increased until a pressure balance has been reached. In the equilibrium state, there will be a positive pressure inside the beverage capsule, namely a pressure corresponding to a value, which is above atmospheric pressure, causing the fact that the membrane 112, deviate in the outward direction.

The vacuum, which is sealed inside the capsule, thus partially compensates for the pressure generated by the gases developed from coffee powder, 107. The degree to which the vacuum It compensates the gases developed, it can vary, from one form of presentation in accordance with the present invention, to another form of presentation in accordance with the present invention, depending on the volume of the beverage capsule, the coffee mass provided therein , and the type and degree of roasting or roasting of the coffee powder itself. In any case, the vacuum inside the beverage capsule compensates for degassing, at least to an extent that avoids the fact that the gas developed can compromise the structural integrity of the beverage capsule. , and its sealing properties.

In a preferred form of presentation, in accordance with the present invention, the initial vacuum pressure of the capsule, immediately after the sealing stage, will be that corresponding to a value within ranges between 300 mb and 600 mbar , this being, preferably, corresponding to a value within a range between 400 mbar and 500 mbar. After the capsule has been sealed, the gases involved by the coffee powder, during degassing, will continue to accumulate in the cavity, 106, of the beverage capsule, proving the fact that the internal pressure of the Drink capsule, increase, to a value that is above atmospheric pressure, over a period of approximately 5 hours, and that this reaches equilibrium, at a value within a range between 1050 mbary and 1600 mbar, preferably, reaching a value within a range between 1050 mbar and 1350 mbar, over a period of approximately 72 hours.

Additionally, the process, in accordance with the present invention, is configured in such a way that the entire degassing, or substantially all the degassing, occurs inside the beverage capsule, then that it has been sealed. While, the pressure, inside the capsule, will be negative, at the time of sealing, the gases developed, will rapidly increase, the pressure, inside the capsules. In a presentation form, in accordance with the present invention, the capsule will increase to a value above atmospheric pressure, in a time course of less than 5 hours, and this will stabilize, in a time course of approximately 72 hours.

Figure 2 is a series of views, which represent various configurations, for the joining means. As discussed above, above, the joining means, comprises, at its bottom end, a plurality of faces or surfaces, which are pressed into the membrane, to join it with the flange or flange , of the capsule body, on a plurality of regions, corresponding to said faces or surfaces.

Figures 2 A and 2 B represent an orthogonal view and a perspective view., In a respective way, of a joining means, 200. As discussed above, above, in this patent application document, The joining means 200 has, in a substantial way, the shape of a hollow cylinder. In the joining means, 200, two grooves, 201 are provided, which results in the fact that, the end of the joining means, 200, is divided into two faces or surfaces, 202, and two spaces or gaps , 203.

When a membrane is pressed into the interior, during the joining stage, as described above, the membrane will be attached to the flange of a capsule body, on the portion of a surface of the flange or flange, corresponding to faces or surfaces 202, of a first class. The membrane in question will remain attached, and will allow the communication of the fluid, between the cavity of the capsule body and the surrounding atmosphere, through the unbound regions, between the membrane and the flange or flange, defined by the gaps or gaps. 203, of the first class.

Figure 2 C represents an orthogonal view of an alternative configuration, in accordance with the present invention, for the joining means, which comprises four faces or surfaces, 204, of a second class, and four spaces or gaps, 205, of a second class. Such type of bonding means will attach a membrane to the flange.

or joining a capsule body, on a plurality of regions, corresponding to each of the four faces or surfaces, 204, of a second class, while leaving the membrane regions corresponding to the four voids or voids , 205, of a second class, not united.

Figure 2 D represents an orthogonal view, of another alternative configuration, in accordance with the present invention, for the joining means, provided with eight faces or surfaces, 206, of a third class, and which is separated by eight spaces or gaps, 207, of a third class. As in the representation which has been described above, above, the faces or surfaces 206 of a class, will define the region, on which a membrane is attached to the flange of a capsule body, and defining, the spaces or gaps, 207, of a third class, the places where it is not united.

Figure 2 E represents an orthogonal view, of another alternative configuration, in accordance with the present invention, for the joining means, which is provided with eight faces or surfaces, 208, of a fourth class, which are separated by eight hollow spaces, 209, of a fourth class. In comparison with the other joining means, shown in Figure 2 D, the faces or surfaces, 208, of a fourth class, are smaller than the faces or surfaces, 206, of a third class, while the spaces or Gaps, 209, of a fourth class, are larger than spaces or gaps, 207, of a third class. As a result of all this, the proportion of the flange or flange of a capsule body, to which a membrane will be attached, by means of the joining device shown in Figure 2 E, is much smaller than what would be achieved by the device of union represented in Figure 2 D, with a corresponding increase in the size of the regions of the flange or flange, to which the membrane remains unbound.

The joining devices can thus be configured in this way to fit, in the best way, the particular application, in which the joining device in question must be used. In the forms of presentation which have been represented above, above, in this patent application document, the joining devices are modified, by adjusting their number and size; however, however, in other forms of presentation, in accordance with the present invention, it could be advantageous to modify other elements, as regards their shape and geometry, such as, their configuration or shape, its thickness, or its location, around the lower end of the joining means.

Thus, in this way, the joining means can be configured, to reduce the time required to apply the vacuum to the capsule body, while still minimizing the aspiration and entrainment of coffee powder, or other coffee granules. edibles, contained inside the capsule body in question. The sealing of the beverage capsules can thus be optimized in this way, in order to achieve maximum performance and minimum cost.

Figure 3 is a flow chart, which represents a process, in accordance with the present invention, for the manufacture of beverage capsules, the said operation comprising, a series of elements. The first stage of the operation is the descaling or decalcification of the capsule body, 300. The empty capsule bodies are stored, in a general way, in a stacked form, one on top of the other, when they are stored, previously to its use, and thus, in this way, it must proceed to its separation, before these can be processed further. In the stage corresponding to the descaling or descaling of the capsule, 300, the capsule bodies are separated, with respect to each other, and these are placed in the proper orientation, to continue the process.

Simultaneously, the coffee preparation process, 301, provides a supply of coffee powder, for packaging, inside the beverage capsules. In the coffee preparation process, 301, the coffee beans are roasted, to the desired degree of roasting, and then they are ground or ground, to the desired degree of fineness.

As discussed above, above, in this document, the gases generated inside the coffee beans, during the roasting or roasting process, develop from coffee. During the aforementioned roasting or roasting process of coffee, and the sealing of the beverage capsule, some degree of degassing will occur. However, however, it is preferable to configure the manufacturing process of the beverage capsules, to minimize degassing out of the capsule, so that degassing occurs, in an essential way, after that the beverage capsule has been sealed. In a preferred form of presentation, in accordance with the present invention, the duration, between the grinding of the coffee, and its supply and arrangement, inside the beverage capsule, is less than ten minutes; Thus, in this way, the taste and aroma of the beverage recently produced, from the beverage capsule, is preserved in the best way.

Additionally, since the coffee is not degassed, before the sealing process, the infrastructure required to degas the coffee in advance is no longer necessary. This makes the sealing operation of the beverage capsule more compact, economical and flexible.

During the product filling and degassing process, 302, a portion of the coffee powder supplied by the coffee preparation process, 301, is placed inside the capsule body, and this is

densifies, so that the coffee settles in the capsule body, and that the amount of gas is minimized in this way. In an alternative form of presentation, in accordance with the present invention, the powdered matter of the beverage can be compacted, for conversion into a tablet, during the coffee brewing process stage 301, which is then positioned , in the capsule body, during the stage of filling and densifying the product, 302.

Ideally, each of the elements of the operation is linked to a stage for transport, 303, where the capsule body is transferred, between the devices, in order to be able to carry out each element of the operation. In an additional way, the fact that the elements, to carry out the process, can be located in proximity, the ones with respect to the others, or even these, can be integrated into each other, will be understood. , so that the time required for the transport of the beverage capsule between the elements is minimized. The procedure thus becomes more efficient in terms of the space required, and more economical.

After the above described, comes the joining and cutting of the membrane, 305, as depicted in views A-D of Figure 1. In this stage, the membrane is attached to the flange or flange of the body of capsule, to a plurality of regions of the flange or flange in question, leaving a plurality of unbound regions, likewise, also, in said flange or flange. The membrane in question is thus cut, in this way, also, to the size which will cover the flange or flange, and the capsule body.

After joining the membrane and cutting, 305, the application of vacuum and sealing, 306, which is represented in Figure 1, views E-H, follows. A vacuum is applied to the body of capsule, removing the gas from its interior, by means of a plurality of regions, not joined, of the flange or flange. Next, the membrane in question is sealed over the entire surface of the flange or flange, keeping it empty inside the capsule.

In beverage capsules, which contain roasted or roasted, ground coffee, as shown here, in this patent application document, it is advantageous, in a particular way, the fact that the existing vacuum inside the capsule, be a pressure reduction, which is high enough to compensate for the pressure generated by the gases developed by the coffee, as it is degassed in the capsule. A normally configured beverage capsule will thus resist the pressure accumulated inside the sealed capsule as a result of the developed gases.

Finally, the capsules are transferred to the distribution, 308, where, these, can be packaged in a container or box, in a case, or a bag or sack, or the like, and then, it is distributed , for sale.

Of course, the present invention is not limited to the forms of presentation which have been described above, above, in this patent application document, and in the accompanying drawings. In this, modifications are possible, in a particular way, as regards the construction of the various elements, or by replacing technical equivalents, without thereby departing from the scope of protection of the present invention.

In a particular way, it should be understood that the present invention can be adapted to make beverage capsules, for the preparation of various kinds of food substances, such as, for example, beverages consisting of broths or consommés, in coffee, in formulas for young infants, in milk, in tea, in teas, or in any combination of these. It should also be understood that edible granules, which comprise the aforementioned food substances, can be supplied in various shapes and sizes, such as those consisting of flakes, grains, granules, granules, powders, crushed materials, or in any combination of these. While the particular form of presentation, in accordance with the present invention, of the present description, is directed to a beverage capsule, which contains a quantity of roasted or roasted coffee powder, it should not be construed as being limiting within the scope of the present invention, as regards the beverage capsules, thus configured.

Additionally, while the forms of presentation which are represented in the accompanying figures, represent a means of attachment, which is configured to attach the membrane to the flange or flange of the capsule body, on a plurality of regions, it should be understood the fact that, it is also feasible, also, a joining device, which acts in this way, only on a region of the capsule or flange of the capsule in question.

The exact configuration and operation of the present invention can thus vary, in this way, from the description provided above, in this patent application document, without thereby deviating from the principle which is described here, in this document. . Correspondingly in accordance with this, the fact is that the scope of this discussion is exemplary, rather than limiting, and thus, the scope of the present invention, is defined in any from the claims, which are derived therefrom, at least in part.
