Abstract
A synthetic resin bottle with a handle of this invention comprises a biaxially drawn and blow-molded PET bottle and a handle, an injection-molded product of the same PET resin, which is fitted firmly to the bottle as an insert. The up-and-down property of the surfaces of the handle inserts, which come in contact with the PET bottle, is adjusted in response to the softening and drawing state of the PET preform that is deformed and molded into the bottle. This adjustment causes the friction resistance to be reduced between the handle inserts and the blow-molded PET bottle. The finely textured up-and-down pattern can be easily formed through the tests and adjustments by the surface treatment inside the mold cavity used for the injection molding of the handle. Thus, the optimum surface properties can be obtained in response to the bottle sizes and the handle shapes. Therefore, this invention requires no separate process, such as thermal crystallization. Bottles, which fully get around the handle inserts, have high fitting strength but no abrasion, can be provided at a low cost.
