ABSTRACT:
A device for producing a plastic blown three-handled container uses a blow mold comprising two mold halves which can be moved towards one another. In the lower region of each mold half a partial handle shell with a wall region is inserted and a groove is provided for the external handles of the three-handled container. The device has a sliding bar for each mold half, the face of which forms at least one part of the blow mold wall when slid into position. The wall region of each partial handle shell extends to the center line of the container. Each partial handle shell has a half of a central handle, which is formed as a half channel, the edges of which extend to the center line of the container. Each sliding bar has a recess for one half of a central handle, and the face of each sliding bar forms the mold wall in the space between the mold halves.
