Thermoforming film container plus tube - by mould tools which grip tube in tapered holes so that when vacuum thermoforming is completed some space allows film to cool round tube

A flexible thin-walled container with at least one film filling or emptying tube for liq. contents is produced by making the container from two adjacent extruded flat sheets of thermoplastic material, thermoforming them under vacuum, and welding them together when closing the thermoforming mould. Before the mould is closed the tube is positioned between the two flat sheets so that, when the mould is closed, the sheets are not only welded together round their edges but are also welded to the tube; the outer end of the tube remains free so that the thermoplastic material/film round it can be cooled in shape. ADVANTAGE - The filling/emptying tube is virtually positioned and welded at the same time as the two halves of the container and in the split line concerned. The method ensures that the film round the tube cools effectively before the mould is opened again, so that it does not adhere to the tube or to the mould.

Process and apparatus for producing hollow articles from two sheets of thermoplastic material

The production of hollow articles from two sheets of thermoplastic material has until now entailed quite considerable expenditure on machinery, irrespective of which process is used. According to the novel process and using the novel apparatus, all that is required is a tentering frame for the two sheets of thermoplastic material to be laid in as well as heating shields arranged above and below this tentering frame and a moulding tool, designed as corresponding half-shell moulds, with vacuum chambers which are able to change position in relation to each other, there being provided however, in particular in the tentering frame, an air blowing-in nozzle, in order to support the moulding operation by compressed air from inside. Once the moulding operation has been completed, the borders to be welded together of the deformed sheets are simply sheared off by increasing the clamping force of the two half-shell moulds. In this way, in the opinion of the inventor, a minimum of expenditure on machinery ...
