A system comprising a capsule (1) and a capsule receptacle (31) of a preparation machine (30), wherein a sealing lip (10) corresponds with a groove (33) of the capsule receptacle (31) in such a way that the sealing lip (10) is received in the groove (33) and enables a tight connection with a contact surface (32) of the capsule receptacle (31).

A dispensing machine includes an injector for supplying water under pressure to a capsule housed in a housing A dispensing device closes the housing, which includes an annular sealing edge for contacting the capsule in the closed configuration.The capsule includes a casing with base and side walls defining a cavity containing a product to be added to water for obtaining a beverage. A flanged edge extends from the side wall. A covering element closes the cavity. A sealing element, associated with the flanged edge creates a fluidic seal with the sealing edge in the closed configuration. The sealing edge includes radial open grooves and radial crests which contact a sealing area of the annular body. The grooves and crests penetrate more deeply into the sealing area during dispensing, to improve the fluidic seal, when the annular body is softened by contact with injected water.

The invention relates to a single-serve capsule (1) for preparing a beverage in a beverage preparation machine, wherein: the single-serve capsule (1) comprises a base element (2), which has a cavity (3) for receiving a beverage raw material, and a capsule cover (4) sealing the cavity (3); the base element (2) comprises a capsule base (5), a peripheral flange (6), and a capsule wall (7) extending between the capsule base (5) and the peripheral flange (6); the capsule cover (4) is attached to the flange (6) along a sealing plane (8); the flange (6) has a peripheral bulge (9) at its outer free end; a sealing element in the form of a sealing bead (10) pointing away from the capsule cover (4) is provided on the flange (6); the sealing plane (8) extends along the flange (6) on the side of the capsule cover (4), between the bulge (9) and the sealing bead (10); and the sealing bead (10) comprises an inner flank (11) on the capsule wall (7) side and an outer flank (12) on the bulge (9) side; characterised in that the outer flank (12) is oriented at a substantially right angle (α) to the sealing plane and the inner flank (11) is oriented at an angle (β) of greater than 80 to less than 90 degrees to the sealing plane (8).

A capsule containing a substance for the preparation of a beverage has an aluminum capsule body and a cover sheet hermetically closing off the capsule. The capsule body has a flange with a deformable sealing ring portion with an inner wall portion extending from and contiguous with an inner base portion of the flange, an outer wall portion extending from and contiguous with an outer base portion of the flange and a bridge portion interconnecting the inner wall portion and the outer wall portion. The bridge portion is located axially spaced from the base portions of the flange. In radial cross-sectional view, a top of the bridge portion axially most remote from the base portions of the flange is flat or has a center plane curved with a radius of curvature larger than two times a wall thickness of the top of the bridge portion.

A beverage pod is assembled to allow the upper extension of the filter to separate from the upper rim of the container upon an application of force upon the extension. An energy director may be provided between the extension and the rim such that when a linear vertical high-frequency energy is applied to the energy director, the energy director may melt and releasably join the extension to the rim. At least one of the extension and/or the rim may have an energy director protruding therefrom. Separating the extension from the rim may form a gap between the extension and the rim to allow the beverage formed within the pod to drain therethrough.

The invention relates to a capsule (10) designed for preparing a beverage upon injection of liquid into the capsule by means of a beverage preparation machine, the capsule (10) having a longitudinal axis (A) and comprising a cup-shaped base body (1) for holding beverage preparation ingredients, a flange-like rim (2) and sealing means (3) wherein the base body (1), the flange-like rim (2) and the sealing means (3) are made integrally from metallic material such as aluminum, as a one piece element, wherein the sealing means (3) comprises a dedicated surface (4) located on the base body (1) at the junction with the flange-like rim (2) and a projection (5) comprising at least one series of arc-shaped protrusions (5a) protruding circumferentially on the flange-like rim (2), characterized in that the dedicated surface (4) and the arc-shaped protrusions (5a) of the sealing means (3) are concentrically arranged such as to form an annular space (6) there-between for receiving at least one sealing surface (21a) of a capsule engagement member (21) of the beverage preparation machine (20).

A capsule is designed for insertion in a centrifugal beverage production device for preparing a beverage from a substance contained in the capsule by introducing liquid in the capsule and passing the liquid through the substance using centrifugal forces. The capsule includes a body having a bottom end and an open end spaced apart in the axial direction, an upper wall for covering the body at the open end along a direction transverse to the axial direction, and an enclosure between the body and the upper wall containing a predetermined amount of beverage substance. The capsule further includes an annular pressure-setting ring configured for adjusting the backpressure in the beverage production device. The pressure-setting ring provides an improved coffee in-cup quality. A set of capsules can have pressure-setting rings of different dimensions for setting different backpressure when engaged in a centrifuging beverage production device.

A capsule containing a substance for the preparation of a potable beverage. The capsule comprises 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 is provided with a plurality of radially extending open grooves. The sealing member comprises a separate crushable element provided on the surface of the outwardly extending flange opposite the cover.

The present invention refers to systems and process associated with beverage preparation based upon the extraction of a single portion (1) of a pre-measured quantity of precursor substance in a brewing apparatus (4), whereby said single portion (1) presents a compostable confinement (2) and can be collected inside of a portion holder (3) that is adapted so that can be retained inside a cavity of said brewing apparatus (4). In particular, the present invention relates addresses the problem of ensuring effective and reliable operation of a single portion (1) in the portion holder (3).

A capsule (1), intended for the preparation of a beverage in a device for making beverages, comprises: a bottom wall (101); a side wall (102) which extends around a longitudinal axis (A); an annular flange (103), wherein an outer surface of the side wall (102) includes a first portion (1021), which is proximal to the flange (103), and a second portion (1022), which is distal from the flange (103); a lip seal (104) which juts from a rear surface (103B) of the annular flange (103) and which extends around the longitudinal axis (A), so that the annular flange (103), the lip seal (104) and the side wall (102) delimit an annular groove (106); a plurality of protrusions (105) disposed around the longitudinal axis (A) and jutting from the first portion (1021) of the outer surface of the side wall (102).
