A funnel insert for a filler tube of a fuel tank for a motor vehicle, the funnel insert being arranged in an end region of the filler tube intended to receive a fuel nozzle, and there being a space between the outside of the funnel insert and the inside of the filler tube, in which space a fluid barrier is arranged. According to the invention, the fluid barrier is in the form of a sealing body arranged on the outer circumference of the funnel insert, which sealing body comprises a sealing lip resting on the inside of the filler tube in portions or circumferentially, and consists of a material having a higher flexibility than the material of the funnel insert.

The present invention relates to a multistage process for producing hollow plastic articles, encompassing the following steps:

Multistage process for producing hollow plastic articles from half shells

The invention relates to a device for partitioning the plastic parisons to give at least one semifinished open-surface product (), where the device encompasses at least one means of partitioning () the plastic parison and one means of drive (). The means of drive may be composed of one, but preferably of two, driven rolls. It has been found that use of the device of the invention can reduce or prevent the production of creasing and irregularity at the margins, i.e. at the cut edges, of the partitioned parisons, i.e. of the resultant semifinished sheets.

Guiding of a cut-open parison

A hollow plastic article is described, with at least one opening and with a structure which has one or more layers, the hollow plastic article comprising at least one layer made from a polyolefin which was prepared using a fluorine-modified chromium catalyst. The use of hollow plastic articles of the invention as plastic fuel containers, gasoline canisters, plastic tanks, or plastic bottles or the like is also described.

The present invention relates to a process for producing hollow plastic articles, encompassing the following steps:

Production of hollow plastic articles

A multilayer composite plastics material, containing at least one layer (A), which consists, to an extent of least 90 wt %, based on the total weight of this layer, of ethylene homopolymers or copolymers, at least one barrier layer (B), which substantially consists of polybutylene terephthalate, and also, if desired, layers of adhesion promoter (C) serving to improve the adhesion between these layers.
