Definitions

the invention relates to a method for manufacturing a metal, body-necked can with an ironed wall, for example one intended for being provided on one open side with an easily opening lid in order thereby to form a beverage can, comprising the stages of reducing the diameter of the can with the ironed wall by necking the wall up a considerable part of the height of the can, to be referred to as body-necking, and applying a neck rim by necking the top rim of the can.
EP 0 733 415 A1 discloses the manufacturing of a beverage can comprising a body with zones having different diameters by drawing a cup from a blank, reducing the diameter thereof by a restraining operation and thereafter locally increasing the diameter by an expanding operation.
the diameter of the rudimentary can body is firstly reduced. Then an expanding process is used to give the can a different shape e.g. in a shaping mould In order to complete the beverage can subsequently a neck rim is formed at the top of the can to which the lid can be fitted.
This gap is taken to be the gap located between the knock-out and the die.
the can rim fits precisely in that gap.
the can rim is thicker than the can wall so that it has sufficient deforming reserve to be necked.
the knock-out diameter is adapted to that thicker can rim. If the knock-out diameter were adapted to the can wall thickness, then the gap would be too small for the can rim. Therefore, adapting the knock-out diameter to the can rim thickness means that the gap is too large for the can wall, so that the chance of the can wall wrinkling increases (see Fig. 1).
the neck applied for body-necking gives the can body rigidity and holds it under tension so that wrinkling is prevented during body-necking.
the method in accordance with the invention makes it possible to body-neck without a knock-out.
the body because of the axial loading of the can during body-necking, the body must be supported during body-necking by applying an internal overpressure.
a centring pin is used with a diameter equal to the internal neck diameter of the can.
the internal diameter of the can neck is then approx. 52.3 mm.
the invention is also embodied in a method for manufacturing a shaped can by inflating a can which is obtained by applying the method in accordance with one of the Claims 1-4.
the material After pressure loads have been introduced in the material by body-necking, the material is better able to stretch and the can is able to be formed to a considerable extent, for example by inflating.
the method in accordance with the invention has been found highly suitable for cans manufactured from a packaging steel suited to wall-ironing, and manufactured from an aluminium alloy suited to wall-ironing.
Fig. 1 shows schematically the result of three sub-processes a, b and c of the method in accordance with the invention.
Fig. 1a shows a wall-ironed can with a ⁇ 66 mm which in Fig. 1b is transformed into a necked can with a 202 neck and a flange.
the 202 necked can is body-necked in a die (1) into a circular cylindrical body with an outside diameter of less than ⁇ 63.5 mm or even less than ⁇ 62 mm.
a hollow centring pin (2) with an outside diameter equal to the internal neck diameter ofthe can, the can is placed under an internal overpressure for example by using compressed air.
Fig. 2 shows schematically the inflating procedure in a shaping mould (3) of the body-necked, wall-ironed, circular cylindrical body from Fig. 1c into a shaped can.
