Abstract
A closure (2) for a container for pharmaceuticals, in particular a sterile container, includes a closure body (2) that is prefabricated from a non-elastic material. The container has a crucible shape with a bottom (3) and a wall (4, 5). At least one piercable opening (8) is incorporated in the bottom (3) of the crucible-shaped closure body (2) and provided for adding or removing liquid pharmaceuticals. The piercable opening (8) is sealed by a sealing element (7). The sealing element (7) is held in a receptacle (12), which is formed by the bottom (3) and a holding element (11) protruding toward the inside in the use position of the closure (1).
