OF EDIBLE PRODUCTS USING SAID CAPSULE
Field of the invention
The present invention refers to the field of capsules for preparing edible products, in particular aromatic beverages such as for example espresso type coffee and similar .
The present invention further refers to a process for preparing edible products using capsules of the type of the present invention.
Background of the invention
The prior art includes different solutions of capsules of the type of the invention, adapted for preparing edible products .
Said capsules typically present an envelope that provides an oxygen barrier and confines an individual portion of edible substance, such as for example roasted ground coffee beans. Moreover, said capsules typically present a wall adapted for entry of an upstream pressurized flow, and a downstream wall adapted for exit of a resulting beverage .
The document CH 605293 discloses a capsule of the type of the present invention presenting a container part
2/ 21 configured in frusto-conic shape that provides an opening and a rim region that develops in the perimeter of said opening, and a lid part that can be united with a rim region of the container part.
One of the problems that have been addressed in this type of capsules is that of sealing of said rim region when submitted to the pressurized flow inside of a respective brewing device.
The documents EP 1654966 Bl, EP 1816934 Bl and EP 1839543 Bl disclose solutions for a better sealing of the rim region of a capsule by sealing means.
The document EP 2012994 Bl discloses a solution whereby the sealing means are injection moulded over the external surface of the container part of capsule.
The documents EP 1849715 Bl, EP 2029457 Bl disclose solutions for providing a better connection of the sealing element to the container part of capsule.
The document EP 2289820 Bl refers the possibility of the sealing means being provided as an integral piece or a piece separate from the container part of capsule, and further, in the previous case, as a piece mounted in releasable manner or as a piece attached to the rim region, for example by means of a welding technique or of an adhesive. This document neither discloses nor advances any suggestion on how to provide a simple retention of sealing means on the capsule.
There is therefore the need for a solution of retention of sealing means in the container part of capsule, of simple construction and adapted so that can be actuated in effective and reliable manner when necessary.
General description of the invention

Description of preferred embodiments of the invention
It is known in the prior art to configure capsules (1) for preparing edible products such as aromatic beverages, inside of product preparation devices (10), such as espresso coffee brewing devices.
A capsule (1) of the type of the present invention (see Figure 1) comprises a container part (2), configured for example in generally frusto-conic shape, presenting a
6/ 21 base wall (21) upstream, and a sidewall (22) that defines an opening (23) downstream, and further presenting a rim region (24) that extends sideways along the perimeter of said opening (23). The capsule (1) further comprises a lid part (3) configured as membrane or folio-like element, and
| adapted | so | that can | be united with | the downstream-oriented | |
| surface | of | said rim | region (24). | ||
| It | is | further | known in the | prior art to | provide a |
| sealing | element (4 | ) configured | in annular | shape and |
provided in the upstream-oriented face of said rim region (24) so that can be compressed by an upstream confining part (11) of said product preparation device (10) when in a position of readiness to operate (see Figure 2).
Said sealing element (4) is typically provided united to the upstream-oriented surface of said rim region (24). Said sealing element (4) can be provided in the same material as said container part (2) , or in a different material.
According to a first inventive aspect, the capsule (1) according to the present invention presents a sealing element (4) of annular shape provided as a loose piece, so that can be displaced along the sidewall (22) and in the proximity of the upstream-oriented surface of said rim region (24), see Figures 3 and 4.
According to a second inventive aspect, the capsule (1) presents a container part (2) provided so that retains said sealing element (4) in the vicinity of the upstreamoriented of said rim region (24), whereby said sealing element (4) is adapted so that can be pressed, by an upstream confining part (11) of said product preparation device (10), against said upstream-oriented surface of said rim region (24) when said capsule (1) is inside of a product
7/ 21 preparation device (10) in a position of readiness for preparing the product.
It is therefore proposed an inventive sequence in the preparation of an edible product based upon said capsule (1) according to the present invention and comprising the steps of providing a product preparation device (10) in an open position where an upstream confining part (11) is apart from a downstream confining part (12), providing a capsule (1) to the interior of said product preparation device (10), in particular a capsule (1) according to any one of claims 1 to 14, whereby said capsule (1) presents a rim region (24) and a sealing element (4), and actuating said product preparation device (10) in a closing movement until reaching a closed position where said upstream and downstream confining parts (11, 12) confine said capsule (1), whereby during said closing movement of product preparation device (10), said upstream confining part (11) displaces said sealing element (4) of said capsule (1) to a position next to the upstream-oriented surface of the rim region (24), so that said sealing element (4) provides a sealing function of pressurized liquid flow between the interior and exterior of said product preparation device (10) .
It is preferred (see Figures 5 and 6) when said sealing element (4) presents a first surface (41) downstreamoriented and adapted so that can be pressed against the upstream-oriented surface of said rim region (24), and a second surface (42) upstream-oriented, whereby said first and second surfaces (41, 42) are different, preferentially develop along non-coplanar planes.
In this sense, it is further preferred (see Figure 5) when said second surface (42) presents a surface
8/ 21 characteristic (43) adapted for providing a sealing connection with a part (11) of said product preparation device (10). This surface characteristic (43) can be embodied as a surface that is non co-planar with the downstream-oriented surface of said sealing element (4), as represented in Figure 5. This surface characteristic (43) can further be embodied as a non-plane surface along a region that is adjacent to the interior perimeter of said sealing element (4) .
It is preferred when said sealing element (4) is provided in a material that provides a stable and substantially rigid form. In particular, it is preferred when said sealing element (4) is provided in a plastic material, and preferentially in a material that is different or of different composition from the material of said container part (2).
It is further preferred (see Figure 6) when said sealing element (4) presents two perimeter regions of different wall thickness, including an interior perimeter region (44) that develops along the interior perimeter of said sealing element (4), whereby said exterior perimeter region is preferentially provided substantially rigid and said interior perimeter region (44) is preferentially provided flexible. This disposition advantageously provides an easier first introduction of the sealing element (4) beyond the retention means provided on the sidewall (22) of the container part (2).
Figures 7 to 10 represent embodiments of a capsule (1) according to the present invention whereby there is provided a plurality of salience zones (25) in the sidewall (22) of the container part (2), whereby said salience zones (25) are adapted so as to retain the sealing element (4)
9/ 21 in the extension of sidewall (22) downstream thereof up until said rim region (24) of the container part (2).
In particular, Figures 7 and 8 reproduce the inferior plane view (that is, from the upstream-oriented base wall (21) ) of an embodiment of capsule (1) according to the present invention whereby there are provided five salience zones (25) in the sidewall (22) of container part (2). As represented, said salience zones (24) correspond to a localized increase of the dimension of exterior perimeter of said sidewall (22), and are uniformly distributed along the perimeter extension.
It is preferred when said salience zones (24) are provided as an integral part of said sidewall (22) of container part (2) . In particular, it is preferred when said salience zones (25) are configured as at least one of a localized variation of shape of said sidewall (22) and a localized variation of wall thickness of said sidewall (22) .
Alternatively, said salience zones can be provided as a piece that is different from said container part (2).
As shall be promptly understood by an expert in the field, said salience zones (25) are adapted so that provide passage of said sealing element (4) in a downstream oriented movement. In this sense, said salience zones (25) are preferentially configured in a downstream-oriented wedge shape, so that provide an increase of perimeter of said sidewall (22) in the downstream direction thereof (vide Figures 9 and 10).
In particular, it is preferred when said salience zones (25) present a projection of height smaller than 2 mm, preferentially smaller than 1 mm, relative to the surface plane of said sidewall (22).
10/ 21
Moreover, it is further preferred when said salience zones (25) are provided so that provide retention of said sealing element (4) along a height extension (hi) of said sidewall (22) that is smaller than 30%, preferentially smaller than 10%, of the total height (h) of said container part (2) of capsule (1) .
