ABSTRACT:
The invention relates to a plastic jug or flask, in particular a plastic jacket of an insulating jug or flask that is produced by injection moulding in a multipart injection mould having axial separation joints, and has on the jacket surface a relief ornament which exhibits substantially vertical and spiral projections defining between them resilient jacet surface strips. The problem underlying the invention is to design the jug or flask so that it can be produced in a two-part injection mould. This problem is solved in that the jacket surface strips (14) make, in the region of the single separating joint of a two-part injection mould, exterior angles with the median axial plane (E) of the insulating jug (1) or of the plastic jacket (2) equal to or slightly greater than 90.degree..
