The invention relates to a method for producing a container which is made of a plastic material and comprises the edge clamping of a flat and flexible part (5) forming a curved surface on the internal face of a hollow body (1). The inventive method consists in bringing the edge of the part (5) into contact with the internal face of the hollow body, in applying a pushing or tensile force on the part in a direction perpendicular to the surface thereof in such a way that radial forces are induced into the part, thereby bringing the edge of the part (5) together with the internal face of the hollow body.

L~invention concerne un procédé de fabrication d~un contenant en matière plastique comprenant la fixation du bord d~une pièce (5) plate et flexible formant une surface courbe sur la face interne d~un corps creux (1), caractérisé par le fait que l~on effectue les étapes suivantes : - mise en contact du bord de la pièce (5) avec la face interne du corps creux, - application d~une force de poussée ou de traction sur la pièce, selon une direction perpendiculaire à sa surface, de manière à induire dans la pièce des forces radiales qui résultent en un rapprochement du bord la pièce contre la face interne du corps creux.
