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.

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 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.

Systems, methods, apparatuses and articles of manufacture for cartridges. A cartridge in accordance with an aspect of the present disclosure comprises a cartridge body, a filter, a beverage material, and a cover.

A food or beverage capsule (200), comprises: a capsule body (201) comprising a cavity (202) and an open end (204) in communication with the cavity (202); an injection wall (205) disposed upon the open end (204) so as to enclose the cavity (202), the injection wall (205) thereby comprising an interior side (206) facing the cavity (202); and a quantity of a food or beverage ingredient disposed within the cavity (202). The capsule (200) further comprises a sealing membrane (207) fabricated from a flexible material and disposed upon the interior side (206) of the injection wall (205), the sealing membrane (207) being attached to the interior side (206) of the injection wall (205) over at least one fixed region (208) of the sealing membrane (207), at least one free region (209) of the sealing membrane (207) extending freely from an edge of said at least one fixed region (208).

A plastics-material capsule casing which, by virtue of its shaping, undergoes hardly any deformation during the extraction operation and provides for improved penetration of the injection needles of the extraction machine. The capsule casing has a corresponding conical lateral-surface wall which, at the upper periphery, has an outwardly projecting flange and, at the opposite end, is fully closed by a casing floor. The casing floor has a peripheral annular wall which merges from the conical lateral-surface wall via two opposing curvatures in an annular wall. The lower periphery of the annular wall merges into a panel via a thinned region which runs in an inclined manner in relation to the interior. The central panel has a wall thickness corresponding to the wall thickness of the lateral-surface wall. The thinned annular surface here forms an injection membrane.

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 capsule containing a substance for the preparation of a beverage by supplying a fluid under pressure into the capsule. The capsule has an aluminum capsule body with an outwardly extending flange and a cover sheet attached to the flange and hermetically closing off the capsule. A deformable sealing ring portion of the flange projects axially from base portions of the flange, to which said cover is attached. The deformable sealing ring portion has 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 said 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. A support member is arranged between the inner and outer wall portions.

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 may be provided with a plurality of radially extending open grooves. The sealing member is integral with the outwardly extending flange and comprises at least one projection projecting from the outwardly extending flange. The projection comprising a projection top and is configured such that its projection top exerts a radial force on the free contact end of the annular element if the capsule is positioned in the enclosing member of the beverage preparation device and the enclosing member is closed by means of a closing member of the beverage preparation device.
