Abstract: A multilayer capsule of the types which cover the neck of wine or liquor bottles is made is made exclusively of aluminum, or at least 98% by weight of aluminum. A production method for preparing the capsule can include forming a capsule body and fixing an aluminum disc in the upper part of the body. Another production method can include cutting a multilayer sheet into suitable size for the capsule; and forming the capsule by deep-drawing.

Abstract: The present invention relates to a foil capsule, bottle, machine for making score lines in a foil capsule, and method for making score lines in a foil capsule. The foil capsule is made of a metal alloy that comprises at least 99.5% by weight of aluminum. The machine for making score lines in a foil capsule comprises a rotary element (30) configured for being inserted in the capsule such that the capsule rotates on a longitudinal axis of the capsule when the rotary element (30) rotates, and at least two cutting elements (31, 32), arranged to make the corresponding cutting lines as the rotary element rotates. The cutting elements (31, 32) are arranged in a mounting (33) configured such that it can rock in a plane about a pivoting axis (35), said longitudinal axis being perpendicular to said plane.
