Abstract

Casting cap for sheet metal cans and the like, of the type having a stem following the mounting flange or sealing the cap, terminating its free end in the form of a piercing tip, having from its outer edge some passage channels that they ascend to the bushing through the packing flange, characterized in that for the formation in the can of a through polygonal insertion hole, cut in several sections and rolled on the edges in an equal manner, the stem, from the penetration tip , it widens conically towards the packing flange or sealing, develops in section with ribs that expand from the tip in the direction towards the sealing flange between these surfaces in the form of a polygon making these ribs directly under the flange of sealing transition to transverse ribs, from whose ribs and to the transverse grooves they ascend inclined surfaces, all developed so that when turning on the corner the emptying cap in the polygonal insertion hole, evenly flanged, this, to achieve a firm pressure seat by means of the sealing flange, is pressed down on the canister on the inclined surface and the ribs with the transverse grooves which thus remain in the area of the can's casing grip without any material abrading effect below the casing of the can in the rotated position, the transverse slots having been developed in a manner that limit the travel of the turn acting as stops that seat against the edge of the insertion hole to avoid an overdraft.
