A device suitable for use as a plastic can, is essentially symmetrical to a plane separating two mould halves and features an outer wall, through which said separation plane runs. One or more projections are provided on each side of said separation plane, and the frontal face of said projection is separated from said separation plane. Viewed along the perpendicular to said separation plane, said projections are set off from one another so as not to overlap. The frontal face of said can features one or more projections that face said separation plane and are separated from said outer wall. |
