Abstract: A closure for a tube which need not be removed for releasing the contents of the tube associated with an original condition protection means. A closure cap is provided and mounted upon the tube in rotational engagement therewith and it contains an opening which may be aligned in a registry with the opening of the tube to allow the dispensing of the contents thereof.

Abstract: In an installation for producing packaging containers such as tubes, from prefabricated tube bodies and end portions of thermoplastic material, which are connected to the tube bodies, a plurality of moulds which are moved on a circulatory path each include an upwardly directed female mould portion and a mandrel which is pivotable about a horizontal axis between a downwardly directed working position and a loading position. A tube body loading station, a material feed station having a nozzle, and a container unloading station are arranged at spacings from each other along the circulatory path, while the female mould portion and the mandrel of each mould are displaced relative to each other on a common working axis. In a plurality of working units including support frames which are moved on the circulatory path, each support frame supports at least the female mould portion and the mandrel of a mould and the actuating mechanism thereof.

Abstract: A moulding tool for producing tube ends and simultaneously connecting them to a tube body, the tool comprising a female mould (1) and a male mould (19) and having a pin movably disposed in the female mould and a bore (22) in the male mould. The pin has a conical portion (25) extending into a conical part (23) of the bore and, when the mould is closed, co-operates with the bore to form a cavity (30) connected to a mould cavity between the male mould (19) and the female mould (1).
