Description

Capsule and apparatus for processing said capsule

Technical Field

The present invention relates to the field of capsules of aromatic substances used in the preparation of beverages, and in particular to the field of capsules for obtaining beverages, such as espresso coffee, by extraction by means of a pressurized fluid flowing through the capsule.

The invention also relates to the field of devices for preparing beverages, in particular by extraction by means of a pressurized fluid flowing through a capsule, such as espresso coffee machines and the like.

Background

Several solutions are known in the prior art, relating generally to capsules belonging to the above-mentioned technical field and in particular to devices and means for respective openings for the passage of a pressurized flow. A commonly practiced solution involves some form of rupture of a given material of construction (e.g., synthetic or metallic material) that is applied to at least certain areas of the capsule, thereby allowing the ingress of a pressurized flow. The rupture of the construction material is generally carried out by mechanical means, perforating it in isolation or jointly with the hydraulic pressure exerted by the flow, or causing the rupture or the breaking of continuity of specific areas of the construction material, previously weakened or provided with a material intended for the breaking of continuity.

Examples of capsules according to this technical field are disclosed in EP1864917a1, WO2004/089772a2 and WO2008/116818a 1.

None of these forms of opening the capsule by means of some form of perforation or rupture of the material of construction of the capsule provides a high degree of process control over the instant of opening or the operating conditions under which it occurs, or over the form or dimensions of the resulting flow channel portion. In fact, the solutions known in the prior art do not allow to provide reproducible channel configurations and total channel areas available for the flow. These aspects determine to a large extent the through-flow rate and therefore have a substantial influence on the quality of the resulting beverage.

There is therefore a need to solve the problem of capsule opening for flow channels by means of simple means and a more reliable mechanism, in other ways than those associated with some form of rupture of the construction material.

Disclosure of Invention

The aim of the present invention is to make available a capsule having greater control over the conditions of opening of the capsule in general, and in particular over the conditions of opening moment, configuration and dimensions of the passage portion, for the purpose of passing through at least one aromatic substance contained within the capsule by means of a pressurized flow of treatment fluid (for example hot water).

Within the scope of the present invention, one should understand that a "capsule" is a receptacle defining an internal volume for collecting the aromatic substance, having at least one zone facing upstream of the flow, configured for example in the form of a substantially cylindrical box or in the form of a double plate, and made of a substantially rigid or substantially flexible and substantially airtight or substantially airtight material.

According to a first aspect of the invention, the above-mentioned object is solved by means of a capsule constituted by at least one construction element provided with an internal volume and at least one external zone facing at least upstream flow, whereby the capsule is provided with at least one closing element, preferably retained in a substantially airtight manner at least in said zone facing upstream flow by means of at least one removable engagement in a respective element clamp having a substantially corresponding cross section.

Furthermore, the closing element is preferably held in such a way that it can be removed from the removable engagement by applying a given in each case corresponding actuating force, which is preferably applied directly on the closing element from the outside, and which is finally at least partially concurrent with a holding force, which is applied at least on the remaining region facing the upstream flow and/or the downstream flow in the direction opposite to the actuating force. The magnitude of this actuation force is preferably defined as a function of the type of removable engagement, the type of construction material and/or the dimensions of the closure element and the return area to upstream and/or downstream flow. According to this first inventive aspect of the invention, the closing element is thus removed from the respective element holder in such a way that it is substantially surrounded by the pressurized flow.

According to the invention, the configuration of the element clamp of each closing element thus precisely defines the portion of the flow passage through the capsule, while the type of removable engagement allows to reliably control the moment of its opening. Furthermore, the body of the closing element therefore acts as a diffusing element of the pressurized flow, in particular inside the capsule, which creates a recirculation zone on the side thereof facing the upstream flow which advantageously reflects itself into the downstream distribution. In this sense, some embodiments of the closing elements prove particularly advantageous, in particular as a function of their position in the capsule and of the drive mechanism.

According to a preferred embodiment of the invention, the capsule according to the invention thus has a closing element, which is preferably arranged substantially centrally with respect to the cross section of the capsule. Alternatively, the capsule has a plurality of closing elements which are eventually arranged asymmetrically with respect to the respective cross section of the capsule.

According to a further preferred embodiment, the closing element is held by means of two or more removable engagements, which are preferably provided and removed in a sequential manner, by means of exerting a respective actuating force on the closing element in each case and/or exerting a holding force on at least a part of the upstream-flow-facing and/or downstream-flow-facing return region.

Another object of the present invention is to provide an advantageous solution, simple and cost-effective in construction, for reliable and efficient closing of the capsule, in particular in terms of its fixation, integrity and preferably substantially airtight conditions. Another related object is a method of avoiding the use of thin films, in particular metal thin films, applied on the areas facing the upstream flow and/or the downstream flow, without limiting the maintenance of the airtight condition to before opening.

According to a further aspect of the invention, the above-mentioned object is solved in such a way that the holding of at least one closing element is carried out in at least one respective element holder, which is preferably configured with a form substantially corresponding to the form of the closing element, by at least one engagement in each case by means of friction and/or by means of positive locking.

In particular, the closing element is held in the respective element holder by means of at least one frictional engagement (i.e. provided substantially as a result of frictional forces or the like between directly adjacent elements) and/or by means of a positive interlock (by engagement between elements provided with a substantially matching form). These forms of retention are preferably carried out by introducing the closing element at least partially inside one (at least one) corresponding element holder, under a pressure as defined previously. In a preferred embodiment, the closing element and/or the corresponding element holder preferably have a substantially cylindrical form. This is particularly advantageous when the closing element has an at least approximately conical or arched profile in its longitudinal direction parallel to the main flow direction.

According to another preferred embodiment, the engagement by positive locking is performed by at least one protrusion engaging inside a corresponding cavity, the cavity and the protrusion being provided in the side of the closing element and/or the element holder, respectively. In a particular embodiment, the locking protrusion is provided in at least one horizontal plane, the locking protrusion preferably being configured symmetrically, more preferably along the entire circumference of the side of the closing element and/or the respective element holder.

According to another preferred embodiment, the closing element is held by means of being located inside a corresponding element holder, preferably by means of a corresponding step in the closing element, which is located on a part of the element holder, preferably on a recess provided in the element holder.

According to a further preferred embodiment, the projections or locking steps which are in engagement by positive locking are configured in such a way that they result substantially flexible, at least in their peripheral regions, in particular when subjected to bending.

According to another preferred embodiment, the closing element has a tubular configuration along at least a part of its longitudinal extension. Alternatively, the closing element advantageously has a substantially circular configuration.

According to another preferred embodiment, the closing element is manufactured in two parts which are arranged in direct interaction in such a way that, by applying an actuating force, at least one of these parts is displaced, thereby releasing the flow channel part. In a particular embodiment, the two portions are configured and interact with each other in such a way that they are displaced in the main fluid flow direction and/or in the transverse direction, thereby releasing at least a portion of the component clamp as a flow channel through a region facing upstream and/or downstream of the flow.

According to another preferred embodiment, the closing element extends at least over a major part of the distance between the area facing the capsule upstream of the flow and the area facing downstream of the flow.

According to a further preferred embodiment, the closing element has in each case approximately equal transverse dimensions, which are preferably slightly larger than the transverse dimensions of the corresponding element clamps arranged on the region facing upstream and/or downstream of the flow.

According to a further preferred embodiment, the closing element has a height which is different from the height of the corresponding element holder. On the other hand, the height of the closing element is preferably dimensioned in such a way that at least a certain actuating force needs to be applied at least during a certain period of time, so that the displacement of the closing element is completely outside the element holder.

According to another preferred embodiment, the closing element is made of a different material, preferably less rigid than the material of the element holder in which the closing element is held, particularly preferably a biodegradable material.

Another object of the present invention is to make available a device for treating capsules according to the present invention, under conditions of high efficiency and control of conditions in general, and in particular of the moment of opening and of the configuration of the passage portion of the capsule.

According to the invention, this object is solved by means of a device for handling at least one capsule according to the invention, comprising at least one fluid injection member and/or at least one injection discharge member, configured and dimensioned in such a way that, during at least a part of the respective movement towards the extraction position, they exert such an actuation force on the respective closing element and/or such a retention force on at least a part of the area respectively facing upstream and/or downstream of the flow, so that the combination of actuation force and retention force produces an actuation force equal to or greater than that necessary for the removal of at least one removable engagement of the closing element. In particular, according to a preferred embodiment, the combination of these forces is sufficient to release at least one flow channel section through the respective element holder.

According to another inventive aspect of the present invention, the fluid injector and/or the injection drain has a cross section substantially corresponding in its form and external dimensions to the internal cross section of the closing element held in the region respectively facing upstream and/or downstream of the flow, so as to allow a positive engagement between the respective parts.

According to a preferred embodiment, the fluid injection member has at least one injection hole, which is preferably arranged asymmetrically with respect to the respective cross-section, so as to direct the flow in a given direction inside the capsule.

According to a preferred embodiment, the flow of pressurized fluid injected inside the capsule exerts hydraulic forces through the fluid injection member and/or generates hydraulic forces from the inside of the capsule according to the invention, which hydraulic forces are preferably exerted directly on the respective closing element.

According to another preferred embodiment of the device according to the invention, the applied mechanical force together with the hydraulic force is equal to or greater than the actuation force necessary to release, preferably release, the closing element from the respective removable engagement with the at least one area facing upstream and/or downstream of the flow.

Detailed Description

Fig. 1a and 1b present external views of two receivers according to the invention, comprising a top view, a side view and a bottom view (from top to bottom of the figure in turn), provided in one embodiment of capsule type (1) (fig. 1 a) and in one embodiment of pod type (1') (fig. 1 b).

Both capsules (1,1') are built up from at least one construction element defining at least one capsule area (2) facing upstream of the flow and preferably also defining a capsule area (3) facing downstream of the flow. As an example, each embodiment of a capsule (1,1') according to the invention is provided with one closing element (5 e) in the upstream-facing region (2) and another closing element (5 s) in the downstream-facing region (3), the closing elements (5 e) and closing elements (5 s) being held in a removable manner in respective element clamps (6 e, 6 s) and being provided in each case centrally with respect to the cross section of the capsule (1, 1'). The element holders (6 e, 6 s) are in this case designed as cross-proposals of construction elements defining capsule zones (2, 3) facing upstream and/or downstream of the flow, respectively. Alternatively, the capsule (1,1') according to the invention may also have only one closing element (5) in the zone (2) facing upstream or more than one closing element (5) in each zone (2, 3) facing upstream/downstream, said more than one closing elements (5) being arranged symmetrically or asymmetrically with respect to the central symmetry axis of each zone (2, 3). Furthermore, the closing element (5) may have at least approximately the size of the area (2, 3) facing the flow upstream/downstream.

Fig. 2 a-2 c and 3 a-3 c illustrate embodiments of a closing element in a capsule (1,1') according to the invention.

Fig. 2 a-2 c show, in sequence from top to bottom, a top view, a cross-sectional view (along the section AA shown in fig. 1a and 1 b) and a bottom view of a first set of embodiments of a capsule (1,1') according to the invention. In a first example (fig. 2 a), only one closing element (5) is provided in the upstream-facing zone (2), whereby the flow outlet is implemented by other means (not shown). In fig. 2b, the closing element (5 e) on the upstream-facing side (inlet of the capsule) is provided in the form of a ring and is arranged in such a way that it engages in a closing element (5 s), which closing element (5 s) is provided on the downstream-facing side (outlet of the capsule) and is provided as a kind of piston. In fig. 2c, the closing element (5 e, 5 s) is provided in the form of a single part that simultaneously performs closing and opening of the sides facing upstream and downstream.

Fig. 3a and 3c show, in views corresponding to fig. 2a to 2c, a second group of embodiments of a capsule (1,1') according to the invention, this time designed for a specific position, e.g. tipping one of the sides so that the flow passes through the capsule in a substantially horizontal direction. Fig. 3a presents an embodiment wherein the upstream closing element (5 e) is provided in a non-centered manner in a higher position with respect to the downstream closing element (5 s), thus inducing a different flow pattern inside the capsule (1, 1'). In the case of fig. 3b, both closing elements (5 e, 5 s) are provided on the same side of the capsule, whereas in the case of fig. 3c, both closing elements (5 e, 5 s) are provided in substantially adjacent sides or areas of the capsule.

Fig. 4 a-4 b and 5 a-5 b illustrate an embodiment of removable retention of a closing element in a capsule (1,1') according to the invention.

Fig. 4a and 4b show an embodiment of a capsule (1,1') according to the invention, now in an initial position of retention and in a next position removed from said retention, respectively, wherein the closing element (5) is retained by frictional engagement. The closing element (5) is preferably arranged under pressure in a respective element clamp in order to ensure an airtight condition of the capsule (1, 1'). In this sense, the form, size and fitting pressure of the closing element (5) in the respective cavity (6) are pre-measured, depending on the type of material used, so that the retention is reliably removed by exerting an externally applied actuating force (F) on the closing element (5) (see detail 01).

Fig. 5a and 5b show another embodiment of a capsule (1,1') according to the invention, again in and removed from the retaining position, wherein the closing element (5) is removably retained in the element holder (6 e, 6 s) by positive interlocking engagement. For this purpose, the closing element (5) has a raised area (7) or protrusion (7) which engages in a corresponding cavity (8) provided in the element holder (6 e, 6 s) -see in detail 01. The projections (7) are preferably symmetrically arranged on at least one horizontal plane along the periphery of the side of the closing element (5 e, 5 s) and directly engage in corresponding cavities (8) provided in the side of the corresponding element holder (6 e, 6 s).

Fig. 6a to 6k show a schematic representation of a particular embodiment of a closing element (5) and a corresponding removable holding in a capsule (1,1') according to the invention, in each case in a first closed position (a) and a second open position (B). In the presented case, the configuration of the closing element (5) and the corresponding element clamp (6) should result in some combination of retention in the frictional engagement and retention in the positive interlock. Thus, a first type of hold should dominate in some cases (fig. 6a and 6 f), while a second type of hold should dominate in other cases (fig. 6b to 6 e). In the case of the embodiment represented in fig. 6b, the closing element (5) is held by means of an element in the form of a step (7) initially located in a corresponding recess (8) provided in the element holder (6), whereas in the case of the embodiment represented in fig. 6c, a positive interlock is produced by means of a cavity (7') provided in the closing element (5), which closing element (5) engages in a corresponding cavity (8) provided in the wall of the element holder (6). In fig. 6d, there is a configuration of the closing element (5) in which the removal can be carried out by applying a force substantially parallel to the flow direction, which force is ultimately non-centered with respect to the closing element.

Fig. 6e to 6h illustrate a particular embodiment of the construction and retention form and removal of the closing element (5), in which the closing element (5) projects itself above the plane defined by the respective zones (2, 3) facing upstream/downstream. In the case of the forms presented in fig. 6e and 6F, the closing element (5) is held under pressure and by applying an actuation force (F)_M) Removal, actuation force (F)_M) Has such a size and/or duration that the closing elements (5) are completely moved out of the respective element holder (6). In the case of the embodiments of fig. 6g and 6h, the closing element (5) has a configuration such as to interact advantageously with a corresponding element on the side of the extraction chamber or beverage preparation machine. In the case of the embodiments of fig. 6g and 6h, there are also closing elements (5) which are actuated by a mechanical actuation force (F) applied by the closing elements (5) not in the main flow direction but along the sides_M) Is displaced so as not to impede the particular channel configuration for flow.

In all the previous embodiments, the closing element (5) is configured as a substantially block-shaped body, which, once it has been removed from the respective obstruction retention of the passage, causes the formation of a flow of pressurized fluid around it. Alternatively, as shown by way of example in fig. 6i and 6j, the closing element (5) may be configured as a substantially tubular body at least along a portion of its longitudinal extension.

Fig. 6k presents a particularly preferred embodiment of the closing element (5) according to the invention, wherein the closing element (5) has two removable retaining positions in the respective element holder (6) provided in the upstream and/or downstream area (2, 3), so that the release of the respective flow channel section is produced at two successive moments by applying two respective actuating forces (F). Thus, the closing element (5) has a first retention anda second hold, the first hold being designed, for example, as a first actuation force (F) to be passed_M) Removed positive interlocking engagement (center pattern), first actuating force (F)_M) In particular mechanical forces, the second holding being to be actuated by a certain complementary actuation force (F)_H) Is removed, supplements the actuating force (F)_H) Especially hydraulic pressure. In particular, the second element may be constructed and manufactured so as to have a lower resistance force, requiring a lower actuation force to remove the corresponding retention with the surrounding construction element.

Fig. 7 a-7 c and 8 a-8 d illustrate embodiments of an extraction device (10) of a capsule (1,1') according to the invention.

Fig. 7a to 7c are cross-sectional representations of a device (10), the device (10) being configured as an injection chamber for the treatment of a capsule (1,1') according to the invention by means of the passage of a pressurized fluid, such as hot water. For the purpose of simplifying the drawing, only the part of the injection chamber (10) that directly interacts with the capsule (1,1') is schematically presented. Fig. 7a corresponds to an initial moment in which the capsule (1,1') has been inserted into the injection chamber (10), while fig. 7b corresponds to a later moment in which the capsule (1,1') has been fixed in the extraction chamber (E) by means of mechanical clamping between the fluid injection member (11) and the injection discharge member (12). Fig. 7c corresponds to an embodiment in which the closing element (5 s) in the zone (3) facing downstream is removed by means of a mechanical retention force exerted on the capsule, eventually causing the side wall of the capsule to bend and thus expel the closing element (5 s) in the main flow direction.

Thus, as shown in fig. 7b, when in the extraction position (E), the fluid injector (11) is brought into alignment with the in each case corresponding shut-off element (5E) held in the upstream-facing region (2), and the injection drain (12) is brought into alignment with the in each case corresponding further shut-off element (5 s) held in the downstream-facing region (3). According to a preferred embodiment, the fluid injection member (11) is configured to follow the movement towards the extraction position (E)Acting on the respective closing element (5 e) to exert a certain mechanical pressure (F)_Me) The projection of (a). Similarly, the injection drain (12) is also configured so as to exert a localized pressure (F), preferably directly, on the respective closing element (5 s)_Me). Mechanical pressure (F)_Me) Is pre-designed in such a way that it results in an actuation force (F) equal to or greater than that necessary to completely remove the closing element (5 e) from the respective element clamp (6 e) and thus release the passage for the treatment fluid. The same principle can be applied to the case where the closing element (5 s) is arranged on the side of the capsule facing the flow downstream by means of an actuation force (F) having an equal value or a different value with respect to the actuation force of the other closing element (5 e). This configuration of actuation of the inlet opening of the pressurized fluid inside the capsule (1,1') has the advantage of representing a minimum pressure loss in the flow.

Furthermore, the flow of pressurized fluid injected by the fluid injection member (11) exerts a hydraulic pressure (F) on the respective closing element (5 e)_HI). Therefore, in another preferred embodiment of the device (10) according to the invention, the mechanical pressure (F) is applied_Me) And hydraulic pressure (F)_HI) Removing only the closing element (5 e) from the respective element holder (6 e), said mechanical pressure (F)_Me) And hydraulic pressure (F)_HI) In combination greater than the actuation force (F) necessary for this purpose. The same principle can be applied to the case where the closing element (5 s) is arranged on the side of the capsule facing the flow downstream.

Fig. 8a to 8d illustrate different embodiments of the interaction between the fluid injection (11) and the respective closing element (5 e) in order to optimize the conditions of the actuation force (F) exerted on the respective closing element (5 e) and to cause the opening of the capsule (1,1'), in each case represented at a time before (top view) and after (bottom view) said opening. In the case of fig. 8a, the fluid injection (11) is configured to engage at least with the closing element (5 e)The combined portion has a substantially circular cross-section with an outer diameter substantially corresponding to the diameter of the closing element (and slightly smaller than the diameter of the corresponding element holder (6 e)). Alternatively, the fluid injection member (11) may have an asymmetrical element of greater extension at least in the engagement portion, so as to engage with a specific portion of the closing element (5 e). According to a preferred embodiment of the invention (fig. 8 c), the fluid injection members (11) have a non-symmetrical distribution of the respective flow passage openings such that the respective flow passage openings are introduced along a certain distribution pattern inside the capsule (1, 1'). The fluid injector (11) may also have a cross section, for example of hexagonal shape, substantially corresponding to the cross section of the closing element (5) or of the corresponding element clamp (6), in order to better transmit the mechanical actuation force (F)_M). According to another embodiment, the extraction device (10) may have more than one fluid injection (11), each of which is in engagement with a respective closing clamp (5 e, 5 e').
