Abstract: A capsule (1) designated for preparing a beverage upon injection of liquid into the capsule by means of a beverage machine, comprises a cup-shaped body (10) and a closing lid (11) through which the beverage is to be dispensed, said closing lid (11) being sealed on said body (10) and defining therebetween an inner volume for holding beverage preparation ingredients, such as ground coffee. The capsule (1) is made of an aluminium alloy of the series 3xxx, and preferably of the aluminium alloy 3004 or 3104. Use for improving the sustainability of the capsules for beverage preparation.

Abstract: 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) comprises a cup-shaped base body (1) for holding beverage preparation ingredients and a flange-like rim (2) with a sealing member (3) comprising an inner and an outer series (4,5) of arc-shaped protrusions (4a,5a), wherein the base-body (1), the flange-like rim (2) and the sealing member (3) are made integrally from metallic material such as aluminum, in which the inner and outer series (4,5) of the sealing member (3) are concentrically arranged on a surface (2a) of the flange-like rim (2) such as to form an annular space (6) there-between for receiving a sealing surface (21a) of a capsule engagement member (21) of the beverage preparation machine (20).

Abstract: 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 ca

Abstract: 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 (20), the capsule (10) having a longitudinal axis (y) and comprising a cup-shaped base body (1) being provided with a closed end (1a) and lateral sidewalls (1b) for holding beverage preparation ingredients and a flange-like rim (2) arranged at an open end (1c) of the base body (1) and radially ending with a curled outer edge (2c); in which—the capsule (10) is in a first state before being used in the beverage preparation machine, wherein the capsule further comprises a sealing member (3) for providing a fluid sealing engagement with a sealing profile of a capsule engagement member (21) of the beverage preparation machine (20), said sealing profile having at least one sealing surface (21a, 21b, 21c), wherein the base-body (1), the flange-like rim (2) and the sealing member (3) are made integrally from metallic material such as aluminum as a one piece ele
