A capsule includes: an aluminum casing extending about an axis, which includes base and side walls defining a cavity containing a product, and a flanged edge extending from the side wall and including an end annular bead; a covering element, fixed to the flanged edge to close the cavity; a cellulose-based ring sealing element, to seal with a dispensing machine. The flanged edge includes a first portion including the annular bead, an annular second portion contiguous with the side wall, and a connecting portion between the first and second portions. The second portion lies on a first plane and the first portion is displaced towards the base wall and is at least at a predetermined distance from the first plane, between the connecting portion and the side wall a seat being defined in which the ring is housed at least partially.

The invention relates to a disposable cartridge filled with a single serve portion of a liquid ingredient to be combined with a base liquid for the preparation of a liquid product, e.g. a beverage concentrate to be combined with water, e.g. carbonated water, for the preparation of a beverage suitable for human consumption. The cartridge comprises a vertically extending channel that extends to a dispensing aperture in the bottom of the cartridge and one or more dispensing passages extending between a reservoir and the outside of the cartridge. The dispensing passages are provided with outlet openings located adjacent the aperture such that the base liquid and the liquid ingredient are dispensed in parallel flows, the liquid ingredient subsequently coating the exterior of the stream of base liquid, such that actual mixing of the liquid ingredient and base liquid only takes place after both have been dispensed.

An apparatus for applying a cellulose-based annular body to a perimeter flange of a container includes a supporting unit and an operating unit. The supporting unit has a seat to receive a body of the container and is surrounded by an annular portion on which the annular body and the flange rest, such that the annular body is interposed between the annular portion and the flange. A heating device heat the annular body. The supporting unit includes an annular recess, surrounding the annular portion, to at least partly house an annular end bead of the flange. The apparatus includes a forming device, movable along a respective axis of movement between a far position and an engaging position. In the engaging position, the forming device engages and deforms the annular bead pushing said annular bead into the annular recess.

A capsule includes a cup-like capsule body with a circumferential side wall, a transverse base wall at a first end of the side wall, and a radially outwardly protruding flange encircling the side wall at its second end, and a multi-layered sealing ring lying against the flange while encircling the side wall. The sealing ring includes a compressible layer of fibrous and/or cellulose and/or paper material and an outer shielding layer of a liquid-impermeable material, where the shielding layer is provided on an outwardly directed external surface of the sealing ring and where the shielding layer is configured for shielding the inner compressible layer of fibrous and/or cellulose and/or paper material against pressurized liquid during beverage production.

A capsule for preparing a beverage by injection, within the capsule, of a fluid under pressure, comprising: a cup-shaped body, which in turn comprises a side wall which is substantially frustum-shaped and delimits an opening and a blind bottom, and a membrane for closing the opening of the cup-shaped body in order to delimit a containment chamber configured to contain a food substance for preparing the beverage; an internal filter being proximate to the blind bottom, the internal filter comprising a bottom wall which comprises a substantially circular central region, the central region being arranged in contact with the blind bottom of the capsule and being surrounded by a circumferential distribution groove which is open toward the blind bottom.

A reinforcement ring for capsules for obtaining beverages, for example coffee, comprising a side wall and a flat surface, preferably having a uniform thickness, protruding from the side wall. The reinforcement ring is characterized in that the side wall comprises a groove at the extremity opposite the flat surface, so as to reduce the thickness of the side wall at the extremity and to reduce the total amount of material used to produce the reinforcement ring. The reinforcement ring can be used to reinforce the body of a capsule for obtaining beverages for example made of a filtering material. A machine for welding the reinforcement ring to the capsule body and to a system for producing beverages comprising a container into which the capsule with the reinforcement ring is inserted during the step of supplying pressurized water.

The invention relates to a disposable cartridge filled with a single serve portion of a liquid ingredient to be combined with a base liquid for the preparation of a liquid product, e.g. a beverage concentrate to be combined with water, e.g. carbonated water, for the preparation of a beverage suitable for human consumption. The cartridge comprises a vertically extending channel that extends to a dispensing aperture in the bottom of the cartridge and one or more dispensing passages extending between a reservoir and the outside of the cartridge. The dispensing passages are provided with outlet openings located adjacent the aperture such that the base liquid and the liquid ingredient are dispensed in parallel flows, the liquid ingredient subsequently coating the exterior of the stream of base liquid, such that actual mixing of the liquid ingredient and base liquid only takes place after both have been dispensed.

The invention relates to a capsule for containing a substance for preparing a beverage by placing the capsule in the cavity of a piston. The capsule has a body with a rim and a sealing ring which is attached to the lower wall of the rim. The sealing ring has an upper face bearing on the lower wall of the ring and a free lower face. The capsule has an inner bearing surface and an outer bearing surface each projecting from the rim forming a groove that is arranged to sealingly receive the peripheral edge of the piston during the preparation of the beverage. At least the outer bearing surface is formed on an inner wall of a ring and formed in one part on the free lower face of the sealing ring.

Capsule containing a substance for the preparation of a potable beverage, the capsule having an aluminum capsule body having a side wall and an outwardly extending flange and a sealing member at the outwardly extending flange for providing a fluid sealing contact with an enclosing member of a beverage preparation device. The beverage preparation device comprises an annular element having a free contact end which may be provided with a plurality of radially extending open grooves. The sealing member is integral with the outwardly extending flange and comprises a projection. The sealing member comprises a single annular projection comprising a projection top projecting from an inner projection foot radially outside of a flat inner flange portion extending between the capsule body side wall and the projection and an outer projection foot radially inside of a flat outer flange portion extending between the projection and the curled outer edge. The flat outer flange portion is axially spaced from the flat inner flange portion towards the bottom of the capsule body or the flat outer flange portion and the flat inner flange portion are in line the flat outer flange portion and the flat inner flange portion are in line and a radially outer wall of said projection is oriented transverse to the flat outer flange portion.

A capsule is proposed herein including: a casing that extends about an axis,whichincludes a base wall and a side wall defining a cavity containing an initial product to be joined to a fluid to obtain a final product, and a flanged edge extending from said side wall; a covering element, fixed to the flanged edge to close the cavity; a sealing element, associated with the flanged edge to make a fluidic seal with a dispensing machine; wherein the sealing element includes a cellulose-based ring; and wherein the ring includes a stratified structure including at least two cellulose-based layers, between which there is an outer layer arranged towards the outside and configured to contact the dispensing machine and an inner layer; a joining layer to enable the ring to be joined to the flanged edge; and a further joining layer, to join together the two cellulose-based layers.
