Abstract: By predetermined selection of tin coating weight in the manufacture of electrolytically tinplated continuous steel strip, cup formation of sheet metal blanks cut from such tinplated flat rolled steel with the selected tin coating weight disposed internally, selective reduction of sidewall gage and coating weight, maintenance of tin coating weight on the interior surface of the bottom wall, and selective organic coating, the present invention enables production of special container packs, previously limited to three-piece containers, from unitary seamless can bodies. Selected tin coating weight on the interior surface of the bottom wall of the can body is maintained throughout the manufacturing process and this surface is exposed to container contents. The sidewall interior surface of the can body is protected from exposure to container contents by an organic coating.

Abstract: Draw processing flat-rolled sheet metal substrate preselectively precoated on each surface with organic coating and draw lubricant into one-piece can bodies ready for assembly into sanitary packs free of any requirement for washing, organic coating or repair of organic coating after fabrication and before such direct usage. Selective organic precoating includes embodying a blooming compound which is made available as draw lubricant responsive to heat and/or pressure of draw forming; also, surface application of a draw lubricant after curing of the organic coating. Combined lubricant on each surface is verified before start of fabricating. Draw-forming of tensile strength sheet metal is controlled over side wall height by clamping solely between planar clamping surfaces and by interruption of draw to establish a flange at the open end of cup-shaped work product. Surface area of the cavity entrance zone for each die is preselected along with curved surface transition zone on draw punch in relation to sheet metal substrate starting gage. Nesting of curvilinear clamping surfaces of the prior art is eliminated during redraw of work product. The curved transition zone of cup-shaped work product is reshaped prior to redraw.

Abstract: Composite-coated flat-rolled steel, product, method of manufacture and method of fabrication in which single or double-reduced low-carbon steel, after surface preparation, is flash-coated with tin (about 0.05 #/bb) which is alloyed with the base metal. Dichromate treatment passivates the tin-iron alloy surfaces depositing a chrome oxide layer prior to application of an organic coating (about 3 to 15 mg/in.sup.2 to each surface). Enhanced coating adhesion of the organic coating enables draw-processing of the double-reduced steel base metal substrate into unitary can bodies without damage to coating or substrate.

Abstract: New technology for deep drawing can bodies for use in the manufacture of two-piece cans for food and beverage products from precoated flat-rolled sheet metal can stock in which damage to can stock precoated on both surfaces with an organic coating is avoided and draw-forming of the side wall is controlled to decrease metal requirements. A draw die cavity entrance (47, 74) is selected to provide at least a major portion of its curvilinear surface having a radius of curvature of about five times nominal sheet metal thickness gage, or less, e.g. a maximum radius of curvature of 0.04 inch is used for the more commonly used can stock materials. During cup redraw, nesting of curvilinear clamping surfaces (21, 26) of the prior art is eliminated; the compound curvilinear juncture of a work product cup, between its end wall and side wall, is reshaped about a clamping ring compound curvilinear transition zone (72) of smaller surface area than the cup juncture and, the sheet metal is clamped solely between planar clamping surfaces (63, 71) during redraw to a smaller diameter utilizing a male punch (66) with a punch nose (79) having a significantly larger surface area than that of the cavity entrance zone.

Single or double-reduced flat-rolled steel, after cleaning, is chemically treated to apply a chrome oxide coating of about three hundred (300) to five hundred (500) micrograms per square foot to each substrate surface followed by utilization of a dual-organic coating system with application and curing of an organic primer to each chemically-treated surface of the substrate followed by application and curing of an added organic coating on at least one such substrate surface; such composite-coating process resulting in an exterior surface of a drawn can body or end wall having at least about two and one-half (2.5) to about five (5) milligrams of organic coating per square inch and an interior can surface with organic coating weight of at least about seven and one-half (7.5) to ten (10) milligrams per square inch. In cup forming applications, both such surfaces are lubricated with a suitable lubricant approved for food and beverage usage prior to cupping and any redraw operation.

Abstract: Composite-coated flat-rolled steel can stock processing and product for fabrication of sheet metal cans, in particular for three-piece, welded or cemented side seam cans. Single or double-reduced, low carbon, flat-rolled steel of a gage in the range of about 55 to 110 pounds per base box is flash coated with tin (0.05 #/bb), which is alloyed with the steel base metal; at least 0.20 #/bb of tin is added to one surface only, flow brightened and water quenched; chemical treatment chrome oxide coating of about 100 to 750 milligrams per square foot is added to both surfaces and an organic coating of 2.5 to 15 milligrams per square inch is added to the surface which is free of flow-brightened tin for disposition internally of a can fabricated from such coated can stock. The equivalent of quarter-pound and higher coating weight tinplate protection is provided while decreasing tin requirements and maintaining three-piece can fabrication properties not available with coating metal substitutes for tin.

Abstract: A full-open, disc-removal, convenience-feature end wall closure with raw edge metal protection and improved easy-open features includes a peripherally-located scoreline defining the disc to be removed, a back scoreline located within the disc and a longitudinally rigid (non-lanced) opener made integral with the disc by a rivet. A multi-layer fold of sheet metal contiguous to the peripheral scoreline shields residual scoreline metal which remains with the disc. The back scoreline includes a central vent portion and a pair of legs extending, one each from such central portion, on opposite sides of the rivet, toward the adjacent portion of the peripheral scoreline so that, after rupture of the vent portion of the back scoreline, rupture of the back scoreline legs tends to move the opener in a radial direction; radially-directed movement is controlled and the working end of the opener is turned inwardly, in relation to a container, and toward a prescribed location with respect to the peripheral scoreline so as to facilitate initial rupture. The remainder of the peripheral scoreline is severed by continuing arcuate movement of the handle end of the opener which places the handle end radially outboard of the container for lever action opening using the chime seam as a fulcrum.
