ABSTRACT The invention relates to a process for the production of a plastic canister from thermoplastic material in the 5, 10, 20 and 30 liter range which has an upper wall, four side walls and a bottom and suitable corner sections. The bottom is fabricated in the hot state of the thermoplastic material by a squeezing-off operation. The upper wall and side walls are injection-molded, with the side walls being substantially longer than would correspond to the height of the finished canister. The blank is at least in the lower region of the side walls raised to the squeezing-off temperature and placed in a divided blow-mold and there put under blowing pressure, and the bottom is squeezed off from the lower lengths of the side walls in known manner.
