DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a self-adhesive label and to a method of producing a self-adhesive label carried on a backing of release material.
A number of self-adhesive multilaminar leaflet or booklet labels are known, together with methods for their manufacture. For example, GB-A-2247662 discloses a multilaminar label in which a leaflet or booklet is adhered to a self-adhesive support piece and the entire assembly is covered with a self-adhesive plastics overlaminate.
The present invention aims to provide an improved self-adhesive label and method of producing such labels.
Accordingly the present invention provides a self-adhesive label carried on a backing of release material comprising a multilaminar label portion, a tab portion comprising a sheet which is spaced from the multilaminar label portion and a self-adhesive laminar material overlying and adhered by the self-adhesive surface thereof to the upper surface of the multilaminar label portion and the tab portion, a region of the laminar material being disposed between the multilaminar label portion and the tab portion and adhered directly to the backing of release material.
The present invention further provides a method of producing a succession of self-adhesive labels carried on a length of release backing material, the method comprising the steps of: (a) providing a plurality of multilaminar labels, each having a front panel and a rear part, the front panel including an edge portion extending beyond the rear part and which is provided with at least one cutout therein; (b) disposing the multilaminar labels in succession over a web of release backing material whereby each cutout overlies and exposes a respective portion of the release backing material; (c) adhering a web of self-adhesive laminar material over the succession of multilaminar labels whereby each front panel and each cutout is at least partially covered by the laminar material so that in each cutout the laminar material is adhered directly to the backing of release material; and (d) die-cutting through the laminar material and the multilaminar labels as far as the release backing material thereby to form a plurality of self-adhesive labels, each self-adhesive label comprising a multilaminar label portion, a tab portion spaced from the multilaminar label portion and having being formed from the front panel thereof and a portion of the laminar material adhered to the upper surface of the multilaminar label portion and of the tab portion, the laminar material having a region thereof which is adhered directly to the backing of release material between the multilaminar label portion and the tab portion.
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 perspective view of a folded leaflet for use in manufacturing self-adhesive labels in accordance with a first embodiment of the present invention;
FIG. 2 is a plan view of an assembly of the leaflets of FIG. 1 when disposed in succession on respective self-adhesive support pieces carried on a backing of release material;
FIG. 3 shows the assembly of FIG. 2 following an overlaminating step with a transparent self-adhesive laminar material and a subsequent die-cutting step to produce a plurality of self-adhesive labels in accordance with the first embodiment of the present invention;
FIG. 4 is a side view of a self-adhesive label carried on a backing of release material in accordance with the first embodiment of the present invention;
FIG. 5 is a schematic side view of an apparatus for producing labels in accordance with a second embodiment of the present invention;
FIG. 6 is a side view of a self-adhesive label carried on a backing of release material in accordance with a third embodiment of the present invention;
FIG. 7 is a perspective view of a self-adhesive label carried on a backing of release material in accordance with a fourth embodiment of the present invention; and
FIG. 8 is a plan view of an assembly of multilaminar labels carrie
