- the first portion is in this case adapted so that it can be impinged by one of the capsule confining parts of said beverage preparation device and is thereby pushed relative to the side wall of the container part and pressed onto the rim region thereof when the capsule is located within a respective product preparation device and the latter is in a product preparation position.
- said capsule is adapted to prepare beverages such as for example aromatic beverages including espresso coffee and the like, by means of a pressurized flow flowing through a portion of edible substance collected within said capsule.
- beverages such as for example aromatic beverages including espresso coffee and the like
- the container part of said capsule is provided in an oxygen barrier-providing material, as known in the state of the art, including in aluminum or an aluminum alloy, and in plastic or in a plastic composite.
- the capsule disclosed by the present invention is particularly adapted to contain an individual portion of edible aromatic substance, such as for example roasted and ground coffee, tea or the like, and has capsule walls arranged in direct opposition and adapted for injection of a fluid flow pressurized upstream, and discharge of the resulting aromatic drink downstream.
- edible aromatic substance such as for example roasted and ground coffee, tea or the like
- An associated objective of the present invention is to provide a process for producing capsules, in particular of a capsule according to the present invention.

- capsules (1) it is known in the state of the art to configure capsules (1) to prepare edible products such as espresso coffee and other aromatic drinks, so that it can be operated in a fluid-tight manner, including by means of impinging with a flow of pressurized fluid, within product preparation devices (10), such as espresso coffee extraction devices.
- the capsule (1) of the type of the present invention (see Figure 1) comprises a container part (2), configured for example in a generally frusto-conical shape, having a base wall (21) upstream, and a side wall ( 22) which defines an opening (23) downstream, and further having a shoulder region (24) which extends sideways along the perimeter of said opening (23).
- the capsule (1) further comprises a lid part (3) configured as a membrane or folio-like element, and adapted so that it can be joined with the surface oriented downstream of the rim region (24).
- the capsule (1) according to the present invention presents an annular-shaped sealing element (4) provided as a separate piece, and comprising a first portion of seal (41) adjacent to the shoulder region (24) and a second seal portion (42) extending at an angle with respect to the first seal portion (41) and adapted so that it can be retained by means of an insert. pressurized on the side wall (22) in the vicinity of the bead region (24) and thereby also retain the first sealing portion (41) in position, which is in extensive surface contact with the upstream oriented surface of the bead region (24).
