ABSTRACT:
A covering (A) which is developed as closure for infusion bottles (3) or the like, having a cap (1) adapted to be flanged at its lower edge (11) onto the neck (2) of the bottle, the cap having a hole (9) in its top (8) for the formation of a puncture region, and in order to obtain a structural shape which is of simpler manufacture and more favorable for disposal, the hole (9) is closed by the foil section (16) of a supplementary cap (17) which, as a result of that fact that it extends to the lower edge (11) of the cap (1), can be flanged with the latter and is attached by adherence to the cap (1).
