A lightweight reclosable metal can (1) made from thin gauge, hard temper metal comprises a can body (4) having a drawn and ironed sidewall, a bottom end wall and a neck portion having a diameter substantially less than said sidewall, said neck portion including threads (11) adapted to receive a threaded closure and seal contents in the can, and a method for forming the can.

Threaded aluminum cans and methods of manufacture

A method for necking an end of a metal container include effecting initial deformation, generally radially inwardly, of an axial portion to establish a necked-in generally convex transition portion and an adjacent portion disposed between the transition portion and the container end which is initially generally cylindrical. Both portions are of reduced diameter with respect to the original can body diameter. Sequentially, through the series of formation steps, the portion to be necked-in is further reduced in diameter to produce an outwardly generally convex portion disposed in underlying relationship with respect to an outwardly concave portion. A generally, radially, outwardly directed flange may be established within the end section of the necked-in portion. Apparatus to perform the foregoing forming steps consists of a plurality of die means which are subjected to relative axial movement and contact and reshape the exterior of the container portion that is to be necked-in. An additional embodiment has a necked-in portion having a plurality of alternating convex and concave portions. A further embodiment has a straight angularly, inwardly oriented portion connected to the body by a radius greater than the radius of the connection to the neck. A further embodiment creates an externally threaded necked-in portion for receipt of a threaded closure. Products produced by these methods and apparatus are disclosed.

An extensible and pasteurizable radiation curable coating for metal and a process for preparing a metal article coated therewith are provided. The composition comprises a bulky acrylate or methacrylate monomer; a specific combination of oligomers; and an organofunctional silane adhesion promoter. Optionally, the composition may comprise one or more additives such as a photoinitiator; a coinitiator; abrasion resistance, slip, and flow-out additives; wetting promoters; and extender resin. The process comprises the steps of applying a coating to one surface of a metal article and curing the coating, wherein the coating is as defined above.

A connector and coaxial cable interconnectable via axial compression upon a cylindrical section of a solid outer conductor of the cable. The cylindrical section may be formed in the cable by drawing a cable end into an interference fit between a sleeve and an outer conductor seat formed in the connector body. Alternatively, the cylindrical section may be formed in the outer conductor during cable manufacture and the cylindrical section retained between the outer conductor seat and a crimp ring radially deformed by an angled die face during axial compression. To increase flexibility of a straight walled cable, annular corrugations may be formed in the solid outer conductor with the cylindrical sections at each corrugation peak. The cylindrical section having a length of at least 3 millimeters or 4 times the corrugation depth.

An extensible and pasteurizable radiation curable coating for metal and a process for preparing a metal article coated therewith are provided. The composition comprises a bulky acrylate or methacrylate monomer; a specific combination of oligomers; and an acidic adhesion promoter. Optionally, the composition may comprise one or more additives such as a photoinitiator; abrasion resistance, slip, and flow-out additives; wetting promoters; and extender resin. The process comprises the steps of applying a coating to one surface of a metal article and curing the coating, wherein the coating is as defined above.

A die necking method and apparatus for producing a smooth tapered wall between the container side wall and a reduced diameter neck includes a plurality of rotatable necking turrets that each have a plurality of identical necking substations each having a necking die. The necking dies in the respective turrets have an internal configuration to produce a necked-in portion on the container which has a first arcuate segment integral with the container side wall and a second arcuate segment integral with the reduced diameter neck. The necking substations also have a floating form control element that engages the inner surface of the container to control the portion of the container to be necked. The necked-in portion is reformed in each succeeding turret by dies to produce a smooth tapered wall between the arcuate segments.
