A dispenser of flowable materials from a pouch is disclosed. The pouch has an ear (55) at each of the ends of a transverse seal (53) located at one end of the pouch (57). The dispenser comprises i) a cylindrical container (33) having sides and an open top having a rim, the container being adapted to contain the pouch, and ii) a lid (35) attachable to the rim such that the lid is adapted to trap the ears of the pouch between the lid and the rim and to keep said end of the pouch taut between the ears when the lid is attached to the rim. The lid is also being adapted to allow a spout (41) to pierce the pouch at the taut portion.

Apparatus for dispensing flowable materials from a pouch

Joining of metallic pipe lined with thermoplastic polymer

This invention relates to an injection moulding process for the manufacture of multi-layered articles, especially articles having barrier properties. The process includes clamping a thermoplastic film over the cavity of a mould of an injection moulding process, the film being capable of being stretched. The film is then stretched within the mould by inserting the core of the mould, preferably using a core in which a central part enters the mould and partially stretches the film prior to the remainder of the core entering the mould. The mould is then closed, excess film is trimmed off and polymer is injected into the mould cavity. The resultant article is a multi-layered injection moulded article which, depending on the characteristics of the film and injected polymer, may have barrier properties to oxygen, liquids or the like that are superior to articles moulded from only the polymer. The process is particularly useful in the moulding of containers having a depth:width ratio of at least 0.5.
