CAN END

AND METHOD FOR FIXING THE SAME TO A CAN BODY

This invention relates to an end wail for a container and more particularly but not exclusively to an end wall· of a can body and a method for fixing the end wall· to the can body b means of a double seam.

US Patent 40931'01 (KRASKA) describes can ends comprising a peripheral cover hook, a chuck wall dependent from the interior of the cover hook, an outwardly concave annular re-inforcing bead extending radially inwards frou- the chuck wall and a central panel by an annular outwardly convex bead. This can end is said to contain an internal pressure of 90psi by virtue of the inclination or slopc I.

the chuck wall, bead outer wa i 1 and bead inner wall a line perpendicular to the centre panel. The chuck v slope D° is between 14° and the outer wall slop is less than 4° and the inner wall slope C° is between and 16° leading into the outwardly cqtwqx bead. We ha’.·- discovered that improvements in metal usage can be ; · ie by increasing the slope of the chuck wall and lim the width of the anti peaking bead.

US Patent 421 (KRASKA) describes an alternative design of can end iii which the countersink has inner and outer flat walls, an i a bottom three times the metal thickness. The can end has a chuck wall extending at an angle of approximately 24° to the vertical.

Converse! y.,

EPO340955A describes a can end in which the chuck wall· extends at an angl between 12° and 20° to the vertical.

Our European Pa’ent No. 0153115 describes a method of making a can end -uitable for closing a can body

CA 02222014 1997-11-21 containing a beverage such as beer or soft drinks. This can end comprises a peripheral flange or cover hook, a chuck wall dependant from the interior of the cover hook, an outwardly concave reinforcing bead extending radially inwards from the chuck wall from a thickened junction of. the chuck wall with the bead, and a central panel supported by an inner portion of the reinforcing bead. Such can ends are usually formed from a prelacquered aluminium alloy such as an aluminium magnesium manganese alloy such as alloy 5182.

Our International Patent Application published no. WO93/17864 describes a can end suitable for a beverage can and formed from a laminate of aluminium/manganese alloy coated with a film of semi crystalline thermoplastic polyester. This polyester/aluminium alloy laminate permitted manufacture of a can end with a narrow, and therefore strong reinforcing bead in the cheaper aluminium manganese alloy.

These known can ends are held during double seaming by an annular flange of chuck, the flange being of a width and height to enter the anti-peaking bead. There is a risk of scuffing if this narrow annulus slips. Furthermore a narrow annular flange of the chuck is susceptible to damage.

Continuing development of a can end using less metal, whilst still permitting stacking of a filled can upon the end of another, this invention provides a can end comprising a peripheral cover hook, a chuck wall dependant from the interior of the chuck wall, an outwardly concave annular reinforcing bead extending radially inwards from the chuck wall, and a central panel supported by an inner portion of the reinforcing bead,

CA 02222014 2004-03-09

28589-20(S) characterised in that, the chuck wall is inclined to an axis perpendicular to the exterior of the central panel at an angle between 30° and 60°, and the concave cross sectional radius of the reinforcing bead is less than 0.75mm.

Preferably, the angle of the chuck wall to the perpendicular is between 40° and 45°.

In a preferred embodiment of the can end an outer wall of the reinforcing bead is inclined to a line perpendicular to the central panel at an angle between -15° to +15° and the height of the outer wall is up to 2.5mm.

In one embodiment the reinforcing bead has an inner portion parallel to an outer portion joined by said concave radius .

The ratio of the diameter of the central panel to the diameter of the peripheral curl is preferably 80% or less.

The can end may be made of a laminate of thermoplastic polymer film and a sheet aluminium alloy such as a laminate of a polyethylene teraphthalate film on an aluminium - manganese alloy sheet or ferrous metal typically less than 0.010 (0.25mm) thick for beverage packaging. A lining compound may be placed in the peripheral cover hook.

In a second aspect this invention provides a method of forming a double seam between a can body and a can end according to any preceding claim, said method comprising the steps of:placing the curl of the can end on a flange of a can body supported on a base plate, locating a chuck within the chuck wall of the can end to centre the can end on the can body flange, said chuck having a frustoconical

CA 02222014 1997-11-21 drive surface of substantially equal slope to that of the chuck wall of the can end and a cylindrical surface portion extending away from the drive surface within the chuck wall, causing relative motion as between the assembly of can end and can body and a first operation seaming roll to form a first operation seam, and thereafter causing relative motion as between the first operation seam and a second operation roll to complete a double seam, during these seaming operations the chuck wall becoming bent to contact the cylindrical portion of the chuck.

Various embodiments will now be described by way of example and with reference to the accompanying drawings in which

Figure 1 is a diagrammatic sketch of known apparatus for forming a double seam;

Figure 9 is a side view of.__the cans stacked., one on the other.

In Figure 1, apparatus for forming a double seam comprises a base plaie 1, an upright 2 and a top plate 3.

A lifter 4 mouid ed in the base plate is movable towards and away from a chuck 5 mounted in the top plate. The top plate supports a first operation seaming roll 6 on an arm 7 for pivotable movement towards and away from the chuck. The top plate also supports a second operation seaming roI 1 8 on an arm 9 for movement towards and away from the chuck after relative motion as between the first operation roll and can end on the chuck creates a first operation s~am.

As shown in Fie ire the chuck 5 holds a can end 10 firmly ori the flange support provided by t first operation roll shown clear of chuck he of a can body 12 against lifter.plate 4.

a chuck wall

The can end comprises dependent from the a peripheral curl 13, interior of the curl, an outwardly inwards from concave anti-peaking bead 15 extending the chuck wall to support a central panel

16. Typically the chuck wall, flares outwardly from the vertical at an angle C about 12° to 15°.

The chuck 5 comprises a body 17 having a threaded bore 18 permitting ai tachment to the rest of the apparatus (not shown ) . An annular bead 19 projects from the body 17 of the chuck to define with the end face of

CA 02222014 1997-11-21 the body a cavity to receive the central panel 16 of the . can end. The fit of panel 16 in annulus 19 may be slack between panel wall and chuck.

The exterior surface of thé projecting bead 19 extends upwards towards the body at a divergent angle B of about 12° to. the vertical to join the exterior of the chuck body 17 which tapers off an angle A° of about 4° to a vertical axis perpendicular to the central panel. The outer wall of the chuck 5 engages with the chuck wall at a low position marked D within the 12° shaped portion of the chuck bead 15.

As can ends are developed with narrower anti-peaking beads the chuck bead 19 becomes narrower and more likely to fracture. There is also a risk of scuffing of the can end at the drive position D which can leave unacceptable unsightly black marks after pasteurisation.

Figure 3 shows a sectioned fragment of a typical double seam showing a desirable overlap of body hook 21 and end hook 20 between the can end 10 and can body 12.

Figure 4 shows a can end, according to . the invention, comprising a peripheral cover hook 23, a chuck wall 24 extending axially and inwardly from the interior of the peripheral cover hook, an outwardly concave reinforcing or ahti-peaking bead 25 extending radially inwards from the chuck wall, and a central panel 26 supported or an inner portion panel with 27. The panel wall is substantially upright allowing for any metal spring back after pressing. The chuck wall is inclined to an axis perpendicular to the exterior of the central panel at an angle Ci between 20° and 60°; preferably between 40° and 45°. Typically the cross sectional radius of the antipeaking bead is about 0.5mm.

CA 02222014 1997-11-21

Preferably the anti-peaking bead 25 is parallel, sided, however the enter wall may be inclined to a line perpendicular to the central panel at an angle between 15° to 4-15° and the height h.; of the outer wall may be up to 2,5ram.

This can end is preferably made from a laminate of sheet metal and polymeric, coating. Preferably the laminate comprises an aluminium magnesium alloy sheet such as 5182, or aluminium manganese alloy such as 3004 10 with a layer of polyester film on one side. A polypropylene film may be used on the other side if desired.

Typical dimens ,i ' nis of the example of the invention are:-

<td> d5</td><td> overall diameter (as stamped)</td><td> 65.Θ 3mm</td>

CA 02222014 1997-11-21

From these dimensions it can .be calculated that the ratio of diameter central panel diameter of 47.24mm of can end 65.84 is about 0.72 to to overall

economy the aluminium alloy is sheet metal less than 0.010 (0.25mm).

For in the form of

A polyester film (0.0125mm).

Although this example shows an overall height h.; at

6.86mm we have also found that useful can ends may be made with an overall height as little as 6.35mm (0.25).

Figure 5 shows the peripheral flange 23 of can end 22 of Figure 4 resting on the flange 11 of a can body 12 before formation of a double seam as discussed with reference to Figure 1.

In Figure 5 a modified chuck 30 comprises a chuck body 31 having a frustoconical drive surface 32 engaging with the chuck wall 24 of the can end 22.

The frustoconical drive surface is inclined outwardly and axially at an angle substantially equal to the angle of inclination C° of between 20° and 60°; in this particular example on chuck angle C of 43° is preferred. The drive surface 32 is a little shorter than the chuck wall 24 of the chuck body. The substantially cylindrical surface portion 33, rising above the drive surface 32, may be inclined at an angle between +4° and 4° to a longitudinal axis of the chuck. As in Figure 2, this modified chuck 30 has a threaded aperture to permit attachment to the rest of the double seam forming apparatus (not shown).

In contrast to the chuck of Figure 2 the modified chuck 30 is designed to drive initially on the relatively large chuck wall 32 without entering deeply into the anti-peaking bead 25. Further drive is obtained at the

CA 02222014 1997-11-21 juncture of chuck wail 32 and cylindrical wall 33. as chuck wall of end 2-1 Ls deformed during 1st and 2nd operation seaming Fi-.iure 6 and 7. The chuck 30 shown in Figure 5 has an annular bead of arcuate cross section but this bead is designed to enter the chuck wall without scratching or scuffing a coating on the can end; not to drive on the concave bead surface as shown in Figure 2.

It will be understood that first operation seaming is formed using apparatus as described with reference to

Figure 1.

The early results given in Table 1 showed that the can end shape was already useful for closing cans containing relatively low pressures. It was also observed that clamping of the double seam with the D seam ring resulted in improved pressure retention. Further tests were done using a chuck wall angle and chuck drive surface inclined at nearly 45°: Table 2 shows the improvement observed :Table 2

Table 2 is based on observations made on can ends made of aluminium coated have a chuck wall length with polymer film (ALULITE) to of 5.029mm (0.198) up the 43° slope .

It will be observed that the container pressures

4.83 bar (70.0 psig) and 4.74 respectively were much enhanced by clamping the double achieved for seam.

In order to provide seam strength without use of a clamping ring, modified chucks were used in which the drive slope angle C° was about 43° and the cylindrical surface 33 was generally +4° and -4°. Results are shown in Table 3.

Table 4 shows results of further development to seaming chuck configuration to bring closer the pressure resistance of ring supported and unsupported double seams.

Table 4 identifies parameters for length of generally vertical cylindrical surface 33 on the seaming chuck 30, and also identifies a positional relationship between the chuck wall 24 of the end and the finished double seam. It will be understood from Figure 7 shows that the forces generated by thermal processing or

CA 02222014 1997-11-21 carbonated products are directed towards and resisted by the strongest portions of the completed double seam.

Table. 5 Shows results obtained from a typical seam chuck designed to gi:;e -double seam in accordance with parameters and relationships identified in Table 4.

Typically:- As shown in Figure 8 the chuck comprises a cylindrical land of length '1T typically 1.9mm (0.075) and frustoconical dr i ve surface 32 inclined at an angle i°, typically 43°, L·' the cylindrical to which it is joined by a radius F typically 0.5mm (0.020). Angle X is typically 90°.

IG these can ends have a relatively small centre panel in a stiffer annulus.

Figure 9 shows a can 12a, closed according to this invention, stacked upon a like can 12b shown sectioned so that stacking of the upper can on the lower can end is achieved by a stand lead the chuck wall 24 of the the upper can resting on

31a of the upper can fits inside lower can end with the weight of the double seam 34 of the lower can end.

The clearance between the bottom of the upper can body and lower can end may be used to accommodate ring pull features (not shown) in the can end or promotional matter such as an coiled straw or indicia.

Using the experimental data presented above, a computer programme was set up to estimate the resistance to deformation available to our can ends when joined to containers containing pressurised beverage. The last two entries on the table relate to a known 206 diameter beverage can end and an estimate of what we think the KRASKA patent teaches.
