Adhesive labels on a roll

Abstract

 Self-adhesive lengths of labels (2) on a roll (5) have the disadvantage that they cannot be provided with a tangible warning (3) on the labels (1) since the roll (5) would "overturn" due to the elevations (3) which would all be at the same level in the roll (5).
According to the invention the length of labels (6) is provided with some further elevations (4) on both sides of the labels (1), whereby the web can be wound up in the usual manner, because the distance between the layers in the roll (5) will remain uniform in the entire height of the roll, whereby the required stability is obtained and thus the possibility of using label rolls (5) with tangible warnings (3) in the usual labelling machines.
The subsequent affixing of the warning onto labels, either while the labels are being affixed or subsequently, is hereby avoided.

Description

Background of the invention

[0001] The invention relates to self-adhesive labels on a carrier web forming a length of labels which can be wound up for the formation of a roll of labels, and where each label is provided with one or more warnings which are perceptible by touch.

[0002] Labels for containers containing unhealthy and/or dangerous preparations because the contents are toxic, corrosive or highly inflammable must be provided with a warning which can be perceived by touch. This means that there must be an indication which sticks out from the label, whereby the warning is detected by touch even if the text of the label is unintelligible or illegible.

[0003] One way of applying such a warning to a label is by simply affixing a small self-adhesive label with the tangible warning.

[0004] A dispenser fitted on the labelling machine can be used for this purpose so that the small label is fixed to the main label, either immediately before labelling of the container, or subsequently on the label on the container.

[0005] The use of such small labels with warnings is, however, both expensive and cumbersome. This is due to the manufacture of the label and the extra equipment which is required for affixing them. Add to this the extra handling and monitoring of the label led containers.

Advantages of the invention

[0006] Self-adhesive labels on a carrier web according to the invention, where the length of labels is furthermore provided with one or more elevations, whose height at least corresponds to the height of the warning, which further warnings are placed so as for the wound up lengths of labels to be substantially parallel to each other, have the great advantage that labelling can be performed on existing machines, the reason being that the roll of labels is mounted in the exact same manner as is an ordinary roll of labels. This is due to the fact that the layers remain parallel to each other since the elevated portions ensure that the distance between the layers in the entire height of the web remains the same. This prevents the layers from "overturning" on the base in the machine, and the roll will thus act like any normal roll of labels.

[0007] In a surprisingly simple manner this solves the problem of labelling containers with warnings, because existing labelling machines are immediately applicable, which simplifies labelling and makes it less cost-consuming.

[0008] As disclosed in claim 2, by making the further elevations on the carrier web proper, these will not be transferred with the label to the container, which will therefore only carry the label with the warning.

[0009] As disclosed in claim 3, by placing the further elevations along two of the opposing side edges of the label, the roll is operated independently of the position of the warnings on the label, and the elevations will be only slightly visible on the label.

[0010] As disclosed in claim 4, by configuring the elevations as dots, a simple and unobtrusive elevation is obtained.

[0011] Configuring the elevations as lines, as disclosed in claim 5, causes the distance between the layers of the roll to be held in a very reliable manner thus rendering operation reliable.

[0012] Finally, it is expedient, as disclosed in claim 6, to place the elevations separated from the label so that these will not have to be transferred to the container at all.

The drawing

[0013] An example of an embodiment according to the invention is shown in the drawing, in which

fig. 1 shows a section of a length of labels,

fig. 2 shows the length seen in section II-II in fig. 1,

fig. 3 is an end view of a roll of labels, and

fig. 4 shows the roll seen in section IV-IV in fig. 3.

Description of the embodiment

[0014] Fig. 1 shows an example of a length of labels 6 where the labels 1 with adhesive on their back adhere to a silicon coated carrier web 2 for the formation of a long line of labels.

[0015] The top surface of the label may carry printing.

[0016] Moreover, the label carries a warning 3, which in the shown example is a triangle where the legs of the triangle are elevated from the label. This is clearly seen from the section in fig. 2.

[0017] Along two opposing side edges of the label 1 dotted elevations 4 are provided, which, as shown in fig. 2, have a thickness substantially corresponding to the thickness of the warnings 3. In stead of the position of the elevations 4 shown in the drawing along the outermost side edges, they may be placed on the transverse side edges of the length of labels 6.

[0018] Winding up the web 6 in a roll of labels 5, as shown in fig. 3, is thus performed in a commonly known manner in that the web will act as if its thickness is the same all over.

[0019] As shown in fig. 4, the distance between the individual lengths 6 will be identical, and the web can be wound so as to form a sufficiently compact and stable roll.

[0020] Hence, the layers will not slide during storage or use causing the entire roll to overturn.

[0021] This would indeed be the case were not further elevations 4 applied to the length of labels, in that the warnings 3 alone would give a total elevation in the same level which would result in an unsteady roll causing the layers to tilt around the level of the warnings.

[0022] The warnings 3 and the elevations 4 can be made in different ways. One method would be by means of screen process printing, but other known methods can be applied, such as the application of wax, lac and the like, provided only that the elevations are sure to be felt by touch.

[0023] In stead of placing elevated dots 4 on the label, the elevations can be made as lines. Moreover, these elevations can be placed on a cut off strip on both sides of the label, whereby transfer of the label proper to the container is facilitated, while the strips with the further elevations remain on the web.

[0024] In stead of the shown application of the further elevations 4 on the length of labels, these can be configured on the carrier web 2, either by way of embossing or by the application of an extra strip along the side edges, thus creating a thickening corresponding to the height of the elevations 3 on the labels 1. This ensures that only the label is transferred, such as is the case by the common affixing of labels, and the stability of the roll 5 is ensured since the individual lengths in the roll will remain parallel to each other.

[0025] In the shown example the web holds only one row of labels, but there is no reason why several rows of labels should not be provided, if only further elevations are made to offset the differences in height caused by the warnings 3.
