Abstract
A plastic weld pourer component for connecting to a plastics container part, more particularly a container part of film-like plastics material, comprises at least one welding rib extending circumferentially about a neck portion defining a discharge passage, and having a welding edge or face. The welding edge is provided at a welding flash formed on a rib base portion of the welding rib having a smaller dimension in directions perpendicular to the circumferential direction than that of the rib base portion.

A plastic weld pourer component for connecting to a plastics container part made of film-like plastics material by welding, comprising:
- a tubular neck portion defining an elongated axial through-passage to serve as a discharge passage;
- at least one welding rib formed as one piece with the neck portion and circumferentially extending thereabout, said welding rib including a thick-walled rib base portion radially protruding outwardly from an outer surface of the neck portion and having a peripheral outer edge, and a thin-walled welding flash formed as one piece with said rib base portion on the peripheral outer edge thereof and having a smaller radial dimension than that of the rib base portion;
- wherein a ratio of an axial dimension of the welding flash relative to an axial dimension of the rib base portion immediately adjacent the peripheral outer edge thereof is between approximately 1:3 and 1:10.
A combination of a container part of film-like plastics material in the form of a refill bag, with a weld pourer component of dimensionally stable plastics materials, said weld pourer component comprising a tubular neck portion defining an elongated axial through-passage to serve as a discharge passage of said refill bag, at least one welding rib formed as one piece with the neck portion and circumferentially extending thereabout, said welding rib including a thick-walled rib base portion radially protruding outwardly from an outer surface of the neck portion and having a peripheral outer edge, and a thin-walled welding flash formed as one piece with said rib base portion on the peripheral outer edge and having a smaller radial dimension than that of the rib base portion, wherein a ratio of an axial dimension of the welding flash relative to an axial dimension of the rib base portion immediately adjacent the peripheral outer edge thereof is between approximately 1:3 and 1:10.
