ABSTRACT Plastic jug or flask, particularly a plastic jacket of an insulating jug or flask, having a relief orna- ment on the jacket surface. 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 in- jection mould having axial separation joints, and has on the jacket surface a relief ornament which exhibits sub- stantially vertical and spiral projections defining be- tween them resilient jacket 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 me- dian axial plane (E) of the insulating jug (1) or of the plastic jacket (2) equal to or slightly greater than 90°.
