Abstract
The invention relates to a sealing disk for openings of containers, comprising a metal layer used to inject heat by induction, a layer which can be sealed on the container opening and which can be melted by thermal conduction via the metal layer. The sealable layer is adjacent to the inside of the container when the sealing disk is placed on the container opening. An absorber layer which can extract and/or absorb oxygen from the fluid is provided such that said absorber layer is in contact with the inside of the container when the sealing disk is placed on the container opening.
