OXYGEN-IMPEREABLE, FILLABLE CLOSURE WITH A PUSH BUTTON FOR TRIGGERING
First Claim
1. A fillable closure with a push-button to initiate emptying of a capsule (2) that is moulded into the closure, wherein the capsule (2) is separately fillable and sealable, and contents of the capsule (2) are emptied into a liquid container which is closed with the closure, characterized in that the capsule (2) is provided on either an inside or an outside, or on both sides thereof with a smooth mirror-finish coating of 60 nm to 80 nm thickness of metal or silicon dioxide, using a plasma assisted physical vapour deposition process;
- and after filling, the capsule (2) is sealed with an oxygen-impermeable sealing foil (6); and
that the capsule (2) has a deformable front and side wall, and a volume of the capsule (2) can be reduced through pressurisation on top of the capsule by deformation of the front and side wall of the capsule (2), for cutting open or rupturing the sealing foil (6).

Abstract
A fillable closure is used to initiate emptying of a separately fillable capsule moulded into this closure. The capsule is made oxygen-impermeable on the inside or outside with a vapour-deposited layer of silicon dioxide or metal. The volume of the capsule can be reduced through pressurisation from the top, through deformation of its side walls, for cutting or rupturing a sealing foil. The capsule has an asymmetric push button with a pusher surface, a deformable front and side wall and a stable rear wall. The upper end of the rear wall forms a stationary edge, on which the pusher surface can be pivoted downward through deformation of the front and side wall. On the bottom of the pusher surface, a triangle-shaped blade is formed, which ends in a tip, and its triangle edge forming a cutting edge for piercing and cutting the sealing foil on the bottom of the capsule.
