Abstract

Procédé de fabrication par injection-soufflage. Le procédé consiste à mouler, par injection de matière thermoplastique, une ébauche de forme creuse et à soumettre l'ébauche obtenue à une opération de soufflage intérieur, en vue de lui donner la forme du flacon à obtenir; ce procédé est caractérisé par le fait qu'après soufflage, on obture l'ouverture de l'ébauche par un culot rapporté, qui constitue le fond du flacon, et que l'on enlève, par découpage, le fond de l'ébauche pour former le goulot du flacon. Permet la fabrication de flacons de forme compliquée avec un goulot de faible section.Manufacturing process by injection blow molding. The method consists in molding, by injection of thermoplastic material, a blank of hollow shape and in subjecting the blank obtained to an internal blowing operation, in order to give it the shape of the bottle to be obtained; this process is characterized by the fact that after blowing, the opening of the blank is closed by an attached base, which constitutes the bottom of the bottle, and that the bottom of the blank is removed by cutting to form the neck of the bottle. Allows the manufacture of bottles of complicated shape with a neck of small section.
