Claim:
1. A fillable closure to trigger the emptying of a separately filled capsule that is part of the closure, wherein the closure comprises a closing cap that can be screwed onto a threaded neck of a container and in which the separately filled capsule with a downward facing sealing film can be inserted in closed condition from the bottom, wherein an upper face of the inserted capsule is deformable in design and can be pushed down in an axial direction so that the downward facing sealing film of the capsule breaks or bursts, wherein the separately filled capsule is configured to be filled with contents separately from the closure, and is inserted into the closing cap, wherein the sealing film includes a foil that is airproof and lightproof, wherein an axially downward projecting indentation is formed in the upper deformable face of the capsule, wherein an axially downward projecting profile at a lower inner side of the closing cap fits from above into the indentation consistent with a cross-section of the axially downward projecting profile in the deformable upper face of the inserted capsule, so that the deformable upper face of the inserted capsule can be pushed down with the indentation for the downward projecting profile so that outer lower corners of the indentation are pressed onto the sealing film of the capsule on a side of the sealing film inside the capsule to place the sealing film under tensile stress, and wherein the sealing film includes weakened lines so that the corners are incident on the bisectors of circular segments formed by the weakened lines due to the downward projecting profile passing through the sealing film, and these circular segments can be pivoted down from the corners after bursting the weakened lines and maintained in the downward pivoted position by the downward projecting profile.
