SYNTHETIC RESIN BOTTLE BODY WITH HANDLE

摘要

This invention is aimed at providing a biaxially drawn, blow-molded PET bottle with a handle, which bottle is highly safe and easy to handle, even in the case of large-size bottles with a capacity as large as a few liters. This can be achieved by improving the insert moldability of the handle and by increasing the strength of fitting of the handle to the bottle. Such a bottle with a handle comprises a polyethylene terephthalate resin bottle and a handle, an injection-molded product made of a synthetic resin, which is fitted firmly to the bottle as an insert. This bottle has a recession that has been caved in at the rear of body and also comprises a vertical projecting wall disposed in the central part of the bottom of this recession. The handle comprises a pair of fitting beams disposed in parallel to each other in the standing position and a grip plate integrally disposed to connect between the pair of fitting beams at both the upper and lower ends thereof. Embedded ridges are disposed broadly in the direction of central axis of the preform at the positions where said embedded ridges stem from the pair of the fitting beams and extend from the base toward the front end face while expanding in width, so that the front end faces are opposed to the periphery of the preform under the condition that the handle is set inside the blow-molding tool. A part of the fitting beams and embedded ridges constitute the handle inserts that are fitted to the recession bottom on both sides of the vertical projecting wall of the bottle.
