Abstract

La présente invention concerne un contenant en PET ayant une poignée intégrée, comprenant : un contenant en PET ayant une entrée formé par moulage par injection au moyen d'un étirage et d'un moulage par soufflage d'une préforme ; et une poignée ayant une extrémité supérieure formée d'un seul tenant à l'entrée du contenant en PET, et fixée en étant enveloppée par la surface circonférentielle externe du contenant en PET formée par étirage et moulage par soufflage de la préforme. Puisque la poignée est moulée par injection d'un seul tenant dans un corps de contenant au moyen d'un étirage et d'un moulage par soufflage, il est possible d'augmenter le support et la robustesse de la poignée pendant une utilisation du contenant en PET et, en même temps, le contenant en PET peut être transporté facilement et simplement en raison de l'accouplement de la poignée. De plus, la pression provoquée par le poids du contenant en PET plein de contenu est distribuée par une interaction entre la partie d'accouplement du contenant en PET et une pièce fixe de la poignée et, en raison d'une interaction entre le support et une partie entre un corps de poignée et la pièce fixe, la poignée peut être utilisée de manière sûre.
