Use of a packaging unit having an encompassing wall and possibly a base, wherein the pack is designed substantially in the form of a cylinder, truncated cone, sphere, hemisphere, cartridge, pyramid or in some other way and, possibly together with the base, forms a cup, wherein the pack is used for packaging foods, for example beverage ingredients, medicine, tonics, food supplements and/or foods in liquid, pasty or solid form.

A portion capsule for preparing a beverage in a beverage preparation machine, the portion capsule including a base element with a cavity for receiving a beverage raw material, and a capsule cover sealing the cavity; the base element including a capsule base, a peripheral flange with a peripheral bulge, and a capsule wall extending between the capsule base and the peripheral flange; the capsule cover attached to the flange along a sealing plane; a sealing element in the form of a sealing bead pointing away from the capsule cover on the flange; the sealing plane extending along the flange on the side of the capsule cover, between the bulge and the sealing bead; and the sealing bead including an inner flank on the capsule wall side and an outer flank on the bulge side, both oriented at an angle of 80 to 90 degrees to the sealing plane.

A single-dose capsule for the preparation of a beverage comprises a cup (1) with a collar (10) provided with a sealing ring (20) surrounded internally and externally by centring projections (30.i, 40.i), separated circumferentially from gaps (32,42) and arranged aligned in succession along respective circumferential paths (34, 44).

The present invention relates to a capsule (1), comprising a hollow body (2) made from a first plant material and designed to receive an infusible product (3) made from a second plant material, the body (2) having an opening (4) sealed with a lid to contain the infusible product (3), characterized in that the capsule (1) has at least one breakable protuberance (6) protruding from the body (2) opposite to the opening (4) and punchable by a machine intended to infuse the infusible product (3). The invention also relates to a manufacturing method and a method for using such a capsule (1).

The invention discloses a capsule for use in an extraction machine, having a bottom, a side wall and a cover, which together form a chamber for a substance for extraction. The capsule has a deformable area, which is configured to plastically deform in the outward direction under the conditions present during the extraction and to sealingly interact with a capsule holder of the extraction machine. Furthermore, the invention relates to a method for extraction, in which such a capsule is used.

A capsule body is adapted for containing one or more beverage ingredients for use in a beverage preparation machine. The capsule body includes a base body having side walls defining a cavity for receiving the one or more beverage ingredients, a flange-like rim extending from the side walls and a sealing member adapted to provide a sealed engagement between the capsule body and the beverage preparation machine. The side walls include an inner surface facing the cavity defined by the side walls and an outer surface facing the beverage preparation machine in use. The sealing member is positioned on a surface of the flange like rim that extends from the inner surface of the side walls.

A capsule for preparing a predetermined quantity of beverage with a beverage brewing device is disclosed. The beverage brewing device comprises a receptacle for receiving the capsule. The capsule comprises a cup comprising a circumferential wall, a bottom closing the circumferential wall at a first end, and a lid in use connected to the cup at a second end of the circumferential wall opposite the bottom. The wall, bottom and lid, in use, enclose an inner space comprising the extractable product. At least a portion of a surface of the capsule conceived to, in use, interact with the receptacle is provided with at least one projection for forming a sealing engagement with the receptacle.

The invention concerns system for producing a beverage in a beverage preparation machine, comprising:a capsule (1), said capsule comprising a capsule body (2) with a circumferential annular flange (24), a top membrane (3), a bottom membrane (4) and an opening device (5) provided inside the chamber for opening the capsule by relative engagement of said opening device with the bottom membrane (4) under the effect of a rise in pressure of the injected liquid in the ingredient chamber (22), anda beverage preparation machine (10) comprising a capsule holder (11) and a liquid injection device (12). wherein the liquid injection device and the inserted capsule holder are relatively moveable one to the other so as to clamp the circumferential annular flange (24) of the capsule, andan annular support element (100) positionable between the lower surface (242) of the circumferential annular flange (24) of the capsule and the circumferential annular rim (112) of the capsule holder.

Capsule (1) for use in a beverage preparation machine, said capsule comprising: a capsule body (2) defining a chamber (21), said capsule body comprising: one or more side walls (22), said walls extending axially towards a top opening (23), and a circumferential flange (24) that extends radially outward from the one or more side walls, and a top membrane (3) attached to at least a part of the upper surface (241) of the said circumferential flange and closing the top opening, and adapted to be punctured for liquid injection into the capsule, the top membrane and the flange extending globally along a common plane (P), and a bottom membrane (4), provided inside the chamber (21) so as to delimit between the top membrane (3) and said bottom membrane an ingredient chamber, and an opening device (5) provided inside the chamber and adapted to open the chamber.
