ABSTRACT:
A pour spout for containers made of metal or of a similar material, the containers of which are of the type comprised of a one-piece container body which is closed at the end by means of a seamed top fitted with a pull tab and a pull strip with rivet removable in full or in part. The pull tab has a hinged turning line running diametrically to a rivet which attaches a removable flat area covering a central recess in the form of an inverted truncated cone in the can top marking an underside area on the interior defining the truncated cone-shaped spout sealed by a circular surface also recessed with the aforesaid rivet. Pulling on the pull tab removes this recessed circular surface and the area covering the recess at the same time as the side of the spout emerges to the point of reaching its maximum base diameter and the free spout tip opening is rounded inward along its entire edge.
