Claim of US Patent No. 10,919,690

1. A capsule for preparing a nutritional product in a device configured to supply liquid into the capsule, the capsule comprising:at least one compartment for providing nutritional ingredients for the preparation of the nutritional product in combination with the supplied liquid,
wherein the at least one compartment comprises a liquid impermeable membrane forming a release side of the at least one compartment, the liquid impermeable membrane configured to release the nutritional product from the at least one compartment, and
wherein the capsule further comprises at least one relief element protruding from an opening wall, wherein the at least one relief element is tooth shaped comprising a slanted surface that forms a tip at a first end of the slanted surface, and a second end of the slanted surface is opposite from the first end and is more distant from the liquid impermeable membrane than the tip, wherein the at least one relief element further comprises a base surface connecting the slanted surface to the opening wall, and wherein the at least one relief element comprises a surface perpendicular to the liquid impermeable membrane and extending between the base of the relief element and the tip of the relief element,
wherein the liquid impermeable membrane is free of an aluminium layer and comprises a first polymer layer and a second polymer layer being connected to each other at a respective surface of contact, wherein the first polymer layer comprises a precut and wherein the second polymer layer is free of a precut or weakened line or zone, and
wherein the relief element is positioned to overlap the precut in an axial direction perpendicular to a plane of the liquid impermeable membrane, the precut positioned such that a first end of the precut overlaps the at least one relief element and a second end of the precut does not overlap the at least one relief element when viewed along the axial direction.
