HANDLE MEMBER FOR HOLLOW CONTAINER MADE OF SYNTHETIC RESIN AND HANDLED HOLLOW CONTAINER MADE OF SYNTHETIC RESIN

摘要

PROBLEM TO BE SOLVED: To integrally mold a handled large-sized hollow container by providing a handle member made of a PET resin separately molded by injection molding on the body part of a hollow container made of a PET resin, which is obtained by biaxial stretch blow molding, by insert molding. SOLUTION: A handle member 11 comprising a thermoplastic resin is produced by providing a pair of assembling arm plates 13 to the upper and lower end portions of a handle plate 12 to form the handle plate into an almost horizontal U-shape and providing assembling projections 14 to the assembling arm plates so as to protrude them outwardly so as to be able to assemble the handle plate to the upper side wall surface of a hollow container main body made of a synthetic resin. In this case, the end surfaces of the projections 14 raised from the assembling arm plates are formed into a smooth circular arc shape and a rinforcing beam 15 is provided across the assembling arm plates so as to be positioned on the rear sides of the projections to constitute a ring-shaped handle member 11 wherein the surfaces being in contact with a preform P of the projections 14 are inclined outwardly with respect to the preform to be curved toward the preform and can be bonded to a hollow container comprising a polyethylene terephthalate resin by insert molding.
