In a plastic container manufactured by melting blow molding a heated and molten parison extruded from an extruder, a mouth 3 and/or a specified part of a body 2 has a thicker thickness than the body proper. One or more thick parts of the body 2 are continuously or discontinuously formed over part or all a peripheral, height or helical direction of the body of the container. The container enjoys enhanced rigidity, appearance and functionality even when the thickness of its body is considerably reduced.
L'invention concerne un contenant en plastique fabriqué par le biais d'un moulage par fusion-soufflage d'une paraison extrudée à partir d'une extrudeuse. Selon l'invention, l'épaisseur de la paroi d'une portion prédéterminée du goulot (3) et/ou du fût (2) est supérieure à celle du corps principal du fût, et au moins une ligne de la portion épaissie dudit fût (2) est formée, entièrement ou partiellement, de manière continue ou discontinue, sur la circonférence, la longueur ou le contour du fût du contenant. Ceci permet d'améliorer la rigidité, l'apparence et les fonctions dudit contenant, même si le fût présente des parois fines.
