Abstract
A process for crimping the skirt portion of a thin cap 3 below the lower edge of a ring portion 2 provided on the neck of a bottle. The crimping is carried out by a roller which is provided with a shoulder 8 which prevents the crimping of the skirt immediately below the lower edge of the ring portion and thus prevents the skirt cracking or breaking in the transition region between the portion which covers the ring portion and the crimped region of the skirt. <IMAGE>
Description
SPECIFICATION
Process for crimping caps by rollers and a roller for use in said process
For a long time it has been conventional practice to provide bottles with thin metal sealing caps or thin metal covering caps. The former ensure a sealing function and the latter which are generally thinner and more fragile only have a decorative function as well as the function of making it clearly visible that the bottle has been opened. The retention of such caps is usually fulfilled by having an increased-thickness ring portion on the end of the neck portion of the bottle and after fitting the cap crimping a skirt portion of the cap below the ring portion of the bottle. Thus, it is impossible to remove the cap without tearing or at least damaging it in a visible manner.
This shaping operation of the skirt portion of the cap is carried out by crimping by means of rollers which roll on the skirt portion along a helical path whilst applying the same to the surface of the neck portion. This shaping operation of rapidly transforming a cylindrical or a frustum-shaped skirt into a surface of revolution with a non-linear generating line is a difficult operation, which is made even more difficult by the fact that the caps are generally made from a thin, fragile material, such as aluminium or a tin-lead alloy. This operation is particularly difficult when the skirt portion is required to have sudden diameter changes corresponding to the upper and lower edges of the ring portion of the bottle neck.
French Patents 2 259 047 and 2 387 165 describe the difficulties encountered at these two levels, particularly below the ring, where, before crimping the skirt is extended by an overhanging linear portion.
The present invention therefore relates to a process and to an apparatus preventing the flange-like rounded rolling part of the rollers from applying the skirt to the surface of the bottle neck over a certain distance immediately below the lower edge of the ring portion of the bottle neck.
According to the present invention in one aspect there is provided a process for crimping the skirt portion of a thin cap below the lower edge of a ring portion provided on the neck of a bottle, in which crimping of the skirt portion by means of a roller is prevented immediately below the lower edge of the ring portion by a shoulder provided on the crimping roller.
According to the present invention in another aspect there is provided a roller for use in carrying out the process comprising a roller having a rounded flange portion and above the flange portion a shoulder.
An embodiment of the invention will now be described, by way of an example, with reference to the accompanying drawing, in which: Figure 1 shows in the cross-section a cap during crimping by rollers having a conventional shape, and
Figure 2 shows in cross-section a similar cap during crimping by rollers according to the invention.
Fig. 1 shows a bottle neck 1 having an increased-thickness ring portion 2 provided with a cap 3 with a long skirt which is being crimped below the ring portion 2 by conventional rollers 4 and 5.
Fig. 2 shows a bottle neck 1 similar to that shown in Fig. 1, which has an identical ring portion 2. A cap 3 is being crimped by rollers 4'and 5'according to the present invention.
Each of these rollers 4', 5' has a respective shoulder portion 8, 9 of respective height H, and H2 above the respective rounded flange 6, 7 which has a radius r.
In Fig. 1 it can be seen that when the roller 4 comes level with the lower edge of ring portion 2 it suddenly moves towards the axis X-X until it is stopped by the outer surface of the bottle neck 1. Cap 3 is suddenly shaped with the bend at the start of the crimped portion being an acute angle a.
Fig. 2 shows the roller 4' at the position where it has passed the level of the lower edge of the ring portion 2. Immediately after the flange 6 has adapted to the contour of the edge of ring 2, roller 4' is no longer in contact with the bottle neck by its flange 6 and is instead in contact therewith by its shoulder 8 which rolls on the ring portion 2.
Over a height H, + v below the ring portion 2 it does not apply the cap skirt to the neck surface. Thus, the cap skirt is shaped in a much more progressive manner than in Fig. 1 preventing numerous interruptions and breaks of the cap. The angle a' of the generating line of the cap with the plane of the ring edge is now only approximately 60 instead of 30 for a in Fig. 1. This angle is obviously dependent on the heights H, and H2 of the shoulders 8 and 9, as well as on their diameters D and D2. The optimum values are determined by tests.
In general the second roller 5' exerts a greater pressure on the cap skirt and completes the action of the first roller. The height
H2 of its shoulder is generally less than height
H, of roller 4'.
1. A process for crimping the skirt portion of a thin cap below the lower edge of a ring portion provided on the neck of a bottle, in which crimping of the skirt portion by means of a roller is prevented immediately below the lower edge of the ring portion by a shoulder provided on the crimping roller.
2. A process as claimed in claim 1, in which the shoulder is provided above the rounded flange portion of the roller and the

Claims (5)
1. A process for crimping the skirt portion of a thin cap below the lower edge of a ring portion provided on the neck of a bottle, in which crimping of the skirt portion by means of a roller is prevented immediately below the lower edge of the ring portion by a shoulder provided on the crimping roller.
2. A process as claimed in claim 1, in which the shoulder is provided above the rounded flange portion of the roller and the region of the skirt below the ring portion which is not crimped extends over a distance equal to the height of the shoulder plus the radius of the curvature of the rounded flange portion .
3. A process as claimed in claim 1 substantially as hereinbefore described with reference to Fig. 2 of the accompanying drawing.
4. A roller for use in carrying out the process claimed in any one of the preceding claims, comprising a roller having a rounded flange portion and above the flange portion a shoulder.
5. A roller for use in carrying out the process claimed in any one of claims 1 to 3, substantially as hereinbefore described with reference to and as illustrated in Fig. 2 of the accompanying drawing.
