Abstract
A container closure attachable directly or indirectly to a container neck sealed by means of a pierceable film seal. The provision of a film seal covering the container neck guarantees the user that the contents of the container are authentic and original as supplied by the manufacturer. The film seal is pierced as the closure is adjusted from an intact to an access position on the container neck. In the upper intact position, a safety band remains intact. The closure can be adjusted to the lower access position only after the safety band has been removed, and the film seal is pierced as the closure is adjusted to the lower access position. Ratchet-like serrations may be provided on the inner side of the safety band engaging the container, thus making it impossible to unscrew a screw-type closure without removing the safety band. The safety band may be provided on a separate intermediate piece which may be snap-fitted or screwed onto the container neck. Opening means for piercing the film seal may be provided on the intermediate piece.
