Abstract Apparatus for forming a container from a blow-moldable plastic, and characterized by a hollow handle hingedly connected to a container body. The apparatus includes a tube having a pair of openings, one for blowing the container body, and the other for blowing the handle in a simultaneous operation. This is achieved by introducing the mold parison between the mold halves, part of the parison forming the container body and the other part forming the handle.
