ABSTRACT:
A process and apparatus for making a container or like product having an end face and a tubular skirt extending from it. The container or like is made from a length of tubular thermoplastic material. This length is sleeved over a mandrel, with one end portion projecting from it. This end portion is heated to soften it, constricted inwardly and then moulded between the end of the mandrel and a presser cap. The end face may have a central hole or nozzle formed by moulding around a stem projecting from the end of the mandrel.
