Abstract: A method for forming a threaded dispensing opening for a cylindrical drum container having a generally flat circular closed bottom, a generally flat circular closed top, and a cylindrical side wall comprising the steps of forming an aperture in the drum top and drawing the drum metal adjacent the aperture upwardly to define an upwardly extending annular shoulder. The shoulder is then compressed downwardly to thicken the shoulder and a female threaded portion is formed on the inside of the annular shoulder which is receptive of a threaded closure member.

Abstract: A venting device for use with a container closure cap of the type having a flexible pouring spout which is extendable to a pouring orientation from a nested orientation includes a hollow central body portion having a top end, a base and an interior passageway extending therethrough. Joined to the top end of the central body portion is a generally cylindrical portion and joined to the top of this generally cylindrical portion is a frustoconical portion. The base of the central body portion is integrally joined to a substantially flat flange portion which includes a spaced plurality of outwardly radiating ribs. The venting device is joined to the flexible pouring spout of the container closure cap by means of spacer strips which are heat welded between the venting device and the closure cap thereby positioning the venting device in a concentric relationship to the closure cap.
