DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a self-adhesive label and to a method of producing self-adhesive labels.
It is known to manufacture so-called "extended text" multilaminar self-adhesive labels for application to products, the labels being openable so as to reveal previously hidden printed areas.
SUMMARY OF THE INVENTION
The present invention aims to provide an improved extended text self-adhesive label.
Accordingly, the present invention provides a self-adhesive label comprising a self-adhesive base portion which is adhered by its self-adhesive surface to a backing of release material, a folded leaflet portion which is disposed over the base portion and a self-adhesive overlaminate portion which is adhered by its self-adhesive surface to a part of the top surface of the folded leaflet portion and to exposed parts of the top surface of the base portion on opposed sides of the folded leaflet portion so as to retain the leaflet portion in a folded configuration, the overlaminate portion exposing an end part of the folded leaflet portion whereby the end part can be pulled by user thereby to open the label.
The present invention also provides a method of producing a succession of self-adhesive labels carried on a backing of release material, the method comprising the steps of: material carried on a backing web of release material; of base material; and exposed parts of the top surface of the web of base material; and base material as far as the backing of release material so as to form a succession of self-adhesive labels on the backing of release material, the overlaminating step (c) and the cutting step (d) being carried out so that in each self-adhesive label a portion of a respective folded leaflet is sandwiched between a portion of the overlaminating web and a portion of the base material web, with a part of the folded leaflet portion being exposed.
BRIEF DESCRIPTION OF THE DRAWINGS
Embodiments of the present invention will now be described by way of example only with reference to the accompanying drawings, in which:
FIG. 1 is a plan view of a succession of self-adhesive labels carried on a backing of release material in accordance with an embodiment of the present invention;
FIG. 2 is a section on line A--A of the self-adhesive label shown in FIG. 1;
FIG. 3 is a section on line B--B of the self-adhesive label shown in FIG. 1;
FIGS. 4(a),(b) and (c) show in sequence the web assembly during the manufacture of the self-adhesive labels shown in FIG. 1 in accordance with a first embodiment of the method of the present invention;
FIG. 5 is a schematic side view of an apparatus for producing self-adhesive labels in accordance with the method of FIG. 4;
FIG. 6 is a schematic side view of an apparatus for producing the self-adhesive labels of FIG. 1 in accordance with a second embodiment of the method of the present invention; and
FIG. 7 is a schematic representation of the control system of the apparatus of FIG. 6.
DETAILED DESCRIPTION OF THE DRAWINGS
Referring to FIGS. 1 to 3, there is shown a self-adhesive label 2 in accordance with an embodiment of the present invention. It will be seen from FIG. 1 that a succession of such self-adhesive labels 2 is carried on a backing 4 of release material, such as silicon coated paper. Each label 2 includes a lowermost self-adhesive base portion 6 which is coated on its rear surface with a pressure-sensitive adhesive and is adhered thereby to the backing 4 of release material. The base portion 6 preferably comprises a transparent plastics layer, for example of polypropylene. However, it may be comprised of paper. A folded leaflet portion 8 is disposed over the base portion 4 and extends transversely across the self-adhesive label 2. The folded leaflet portion 8 preferably comprises a paper sheet which has been folded with a plurality of folds so as to have a number of layers. A variety of different folded configurations can be employed in accordance with the present invention. For example, the leaflet portion 8 may have a plurality of f
