摘要： An apparatus for the preparation of a vessel having a handle, which includes an injection mold having a cavity for forming a handle having an endless holding portion and an endless attachment portion; an injection molding mechanism for injecting a resin for the handle into the cavity of the injection mold; a blow-forming or draw-blow-forming split mold having a parting surface that can be closed, cavity assembly which is arranged in the split mold plane-symmetrically with the parting surface and includes an inserting cavity for containing the handle therein, and a forming cavity which has a neck-forming cavity, a barrel-forming cavity, a closed bottom-forming cavity, a recess-forming cavity formed at a part of the barrel-forming cavity so that the diameter of a deepest part of the recess-forming cavity is substantially equal to or slightly larger than the diameter of the neck-forming cavity, a projection-forming cavity for forming a projection to project and extend through the attachment portion almost to the center of the recess-forming cavity, and a flange-forming cavity formed on the top end of the projection-forming cavity to have a section expanded over the projection-forming cavity; a mechanism for supplying a blowing pressure into a preform held by the split mold to effect blow-forming or draw-blow-forming of the preform; a pushing pin that can be pressed into the flange-forming cavity; and a pushing pin-driving mechanism.
