In an apparatus for manufacturing a plastic hollow body which hollow body is open on one end and closed on the other, for the forming of a head piece a withdrawal device rests on a ring-shaped nozzle having a ring-shaped nozzle having a ring-shaped nozzle opening, and for the forming of a plastic tubular segment the bottom elements of blow-mold pieces rest on the ring-shaped nozzle, to provide for blow-molding of the tubular segment by blow means. It is desired to be able to produce a hollow body with a closed head piece and a perforated bottom member. This is achieved in that the withdrawal device is configured for forming a head piece which is closed to the exterior; in that the bottom elements of the blow mold which rest on the ring-shaped nozzle forms a perforation in the bottom member of the body part of the hollow body, which perforation extends over the region surrounded by the ring-shaped nozzle opening; and in that the blow means disposed in the ring-shaped nozzle is associated with or "operative through" the perforation in the bottom member of the body part of the hollow body. Thereby, a hollow body can be manufactured which has a closed head piece and is fillable via the open bottom member.
