Abstract:
A wide mouth plastic barrel with a removable lid and a clamping ring closure is manufactured by extruding a plastic tube into a blow mold and by producing a closed preform. The preform is finish-blown to a barrel body, wherein the blowing air for finish-blowing a barrel body with a closed lid is introduced through a blow nozzle inserted into an intermediate ring of the barrel body and the blowing air for finish-blowing a barrel body with a bung lid is introduced through a bung hole by a blow nozzle and optionally through a blow nozzle in the intermediate ring. After removal from the blow mold, the lid is separated from the barrel body by cutting out the intermediate ring. A seal is inserted into the barrel lid, and the barrel lid is fastened by the clamping ring on a projection of the basic barrel member.
