Title (EN) DRUM CLOSURE AND METHOD OF MAKING
(FR) FERMETURE POUR TONNEAU ET PROCEDE DE FABRICATION
Abstract:
(EN) A method for forming a threaded dispensing opening (13) for a cylindrical drum container (12) having a generally flat circular closed bottom, a generally flat circular closed top (11) and a cylindrical side wall comprising the steps of forming an aperture (36) in the drum top (11) and drawing the drum metal adjacent the aperture (36) upwardly to define an upwardly extending annular shoulder (35). The shoulder (35) is then compressed downwardly to thicken the shoulder (35) and a female threaded portion is formed on the inside of the annular shoulder (35) which is receptive of a threaded closure member.
(FR) Procédé de formation d'une ouverture de distribution filetée (13) pour un conteneur cylindrique en forme de tonneau (12) ayant un fond fermé circulaire généralement plat, un dessus fermé circulaire généralement plat (11) et une paroi latérale cylindrique, comprenant les étapes de formation d'une ouverture (36) dans le dessus (11) du tonneau et l'étirage du métal du tonneau adjacent à l'ouverture (36) vers le haut pour définir un épaulement annulaire s'étendant vers le haut (35). L'épaulement (35) est ensuite comprimé vers le bas pour épaissir l'épaulement (35) et une portion filetée femelle est formée sur l'intérieur de l'épaulement annulaire (35) qui reçoit un élément de fermeture fileté.
