Zusammenfassung:The container comprises a tubular body, two end covers, a guide cone mounted on the outside of one of the covers, and one or more profiling elements provided on one or both covers. The profiling surface of the element, on the side facing the interior of the container body, has a central region which diverges towards the periphery of the element in a direction opposite to the direction of convergence of the guide cone. The profiling element modifies the flow of the metal powder so that the face of the extruded powder nearest the profiling element has a rectilinear form, resulting in a higher yield of useful extruded metal when the container is machined away. L'INVENTION CONCERNE LA METALLURGIE DES POUDRES.LE CONTENEUR FAISANT L'OBJET DE L'INVENTION EST CARACTERISE EN CE QU'IL COMPREND AU MOINS UN ELEMENT DE PROFILAGE DISPOSE DU COTE DE L'UN DES COUVERCLES 3 OU 4 DU CORPS 1 DU CONTENEUR, LA SURFACE DE PROFILAGE 9 FORMEE PAR LEDIT ELEMENT, DU COTE TOURNE VERSLA CAVITE INTERIEURE DUDIT CORPS, COMPORTANT, AU VOISINAGE DE L'AXE DE SYMETRIE DUDIT CORPS, UNE PARTIE CENTRALE 10 ALLANT EN S'ELOIGNANT DE LA PARTIE PERIPHERIQUE 11 DE LADITE SURFACE DANS LE SENS OPPOSE AU SENS DU RETRECISSEMENT DU CONE DE GUIDAGE 5.L'INVENTION PERMET NOTAMMENT DE REDISTRIBUER L'ECOULEMENT DU METAL EN POUDRE DANS LE FOYER DE DEFORMATION DE MANIERE A OBTENIR UN ACCROISSEMENT DU RENDEMENT EN METAL UTILISABLE.
