The fillable closure is used to trigger the emptying of a capsule that can be inserted in the closure and filled separately. The closure consists of a closing cap which can be attached to the neck of a container and in which a separately fillable capsule can be inserted in the closed state from beneath. The region above the inserted capsule on the closing cap forms a push button. A downwardly projecting protuberance is molded on the lower face. The protuberance abuts against the inserted capsule. Using pressure from above, the push button can be pressed to deform an initially convex shape as seen from above into a concave shape, the protuberance pushing the upper face of the capsule and the content thereof downward. A film, which forms the lower face of the capsule, is thus placed under tensile stress such that it breaks or bursts along weakened lines.

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, andwherein 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. 2. Fillable closure to trigger the emptying of the separately filled capsule that is part of the closure according to claim 1, wherein the downward projecting profile forms a cross in its cross-section profile and is integrally formed at the lower face of the closing cap, which cross profile fits in the indentation in the shape of a cross profile in the deformable upper face of the inserted capsule, and wherein, by pressing the cross profile along a turning axis of the closing cap, the indentation in the shape of a cross-profile and its outer lower corners, onto which the cross profile can be pressed, press on the sealing film of the capsule for initially tensioning the sealing film, and wherein the sealing film features two intersecting weakened lines which cross between the outer lower corners so that the corners are incident on the bisectors of the four formed circular segments marked by the weakened lines, and these weakened lines will burst by pressing these lower four corners onto the sealing film in between the weakened lines, and after bursting the four circular segments will be swivelled downward by the corners and afterwards will be kept in the downward swivelled position. 3. The fillable closure to trigger the emptying of the separately filled capsule that is part of the closure according to claim 1, wherein the closing cap is equipped with a twist cap pushed from the top which includes an axially downward projecting tube section with helix-shaped sections on its lower face, wherein these sections rest friction-locked on such equal sections that are present at a tube section at the deformable upper face of the closing cap, so that by turning the twist cap in a counterclockwise direction when seen from above, the tube section friction-locks with the tube section at the deformable upper face of the closing cap and presses the downward projecting cross profile in a downward direction while deforming the surrounding upper face of the closing cap so that the cross profile finally emerges into the indention on the upper side of the capsule and its four corners are pressed onto the sealing film at bisectors of the intersecting weakened lines and thereby break the sealing film along the weakened lines. 4. The fillable closure to trigger the emptying of the separately filled capsule that is part of the closure according to claim 1, wherein the closing cap includes a deformable upper face that forms a push button in the centre so that the axially downward projecting cross profile at the lower face of the closing cap can be moved downward by pressing the push button and the cross profile and thus into the indentation on the upper side of the capsule, wherein the outer lower corners of the same can be pressed on the sealing film of the capsule, and wherein the sealing film includes two intersecting weakened lines so that the corners are incident on the bisectors of the four formed circular segments and the same can be pivoted down from the corners after bursting the weakened lines and maintained in the downward pivoted position. 5. The fillable closure to trigger the emptying of the separately filled capsule that is part of the closure according to claim 1, wherein the closing cap is equipped with a twist cap pushed from the top which includes an axially downward projecting tube section with helix-shaped sections on its lower face, wherein these sections rest friction-locked on such sections that are present at a tube section at the deformable upper face of the closing cap, so that by turning the pushed twist cap, as seen from above, counterclockwise to the tube section at the upper face of the closing cap while its upper face deforms, the cross profile can be moved in an axial downward direction, and wherein an axially downward projecting tube is integrally formed underneath the tube section at the lower face of the closing cap, which fits in a cylindrical indentation in the deformable upper face of the inserted capsule, and by pushing down the tube and thus the indentation, the outer lower corners of the lower edges of the indentation can be pressed on the sealing film of the capsule. 6. The fillable closure to trigger the emptying of the separately filled capsule that is part of the closure according to claim 1, wherein the closing cap includes a deformable upper face, which forms a push button in the centre, wherein an axially downward project tube section is integrally formed at the lower face of the closing cap, which fits into a cylindrical indentation in the deformable upper face of the inserted capsule, and wherein, by pushing down the tube section and thus the indentation, the outer lower corners of the lower edges of the indentation can be pressed onto the sealing film of the capsule. 7. The fillable closure to trigger the emptying of the separately fillable capsule that is part of the closure according to claim 1, wherein the closing cap is equipped with twist cap that is snapped-on from above, which includes an axially downwardly projecting tube section on its lower face with helix-shaped sections, which rest on such sections in a form-fitting manner, which are present at a tube section at the deformable upper face of the closing cap and which can be moved downward in an axial direction by turning the snapped on twist cap, as seen from above, counterclockwise to the tube section at the upper deformable face of the closing cap while said upper face deforms, wherein the axially downward projecting profile of the closing cap is an axially downward projecting triangular or cross-shaped profile that is integrally formed underneath the tube section at the lower face of the closing cap, which fits in the indentation of the inserted capsule, which is a triangular or star-shaped indentation in the deformable upper face of the inserted capsule, so that by pressing down the triangular or star-shaped profile and thus the indentation, the outer lower corners of the lower edges of the indentation are pressed onto the sealing film of the capsule, and so that the sealing film includes weakened lines in the shape of a star so that the outer corners of the indentation are incident on the bisectors of the three formed 120° circular segments of the sealing film and the same can be pivoted downward from the corners after bursting the weakened lines and maintained in the downward pivoted position. 8. Fillable closure to trigger the emptying of the separately filled capsule that is part of the closure according to claim 1, wherein the closing cap features a deformable upper face that forms a push button in the centre wherein an axially downward projecting triangular or star-shaped profile in cross-section is integrally formed at the lower face of the closing cap, which fits in a triangular or star-shaped indentation in cross-section in the deformable upper face of the inserted capsule, and wherein, by pressing the triangular or star-shaped profile and thus the indentation, the outer lower corners of the indentation can be pressed on the sealing film of the capsule, and wherein the sealing film features radial weakened lines, each weakened line being separated from adjacent weakened lines by 120°, so that the outer corners of and, as a result, a lower tube section actuates the pusher button so that the push button can be pushed through pressure from the top while, at first as seen from above, the convex shape deforms into a concave shape in axial direction so that the protuberance pushes down the upper face of the capsule and its content and the film, which forms the lower face of the capsule, can be placed under tensile stress as a result thereof so that the film breaks or bursts along its weakened lines. 9.
