DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a self-adhesive label and to a method of producing a succession of self-adhesive labels carried on a backing of release material.
BACKGROUND OF THE INVENTION
A number of self-adhesive multilaminar labels are known. These labels can suffer from the disadvantage that they can be difficult for a user to open when the self-adhesive label is adhered to a product.
The present invention aims to provide a convenient and elegant solution to this problem.
SUMMARY OF THE INVENTION
Accordingly, the present invention provides a self-adhesive label comprising a multilaminar label portion, a self-adhesive laminar material extending over, and adhered by its self-adhesive surface to, the multilaminar label portion thereby to form two self-adhesive edge portions thereof on opposed sides of the multilaminar label portion, a backing of release material to which one of the edge portions is releasably adhered by a self-adhesive rear surface thereof and an unadhesive portion which is located on the rear surface of the said one edge portion.
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: backing of release material; patches of non-adhesive material to the backing of release material, multilaminar label portions and patches on the backing of release material, the laminar material being adhered thereto by the self-adhesive surface thereof; and portions thereby to form the self-adhesive labels, each self-adhesive label including an edge portion of the laminar material having a respective one of the said patches which is unadhered to the backing of release material.
BRIEF DESCRIPTION OF THE DRAWINGS
An embodiment 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 labels in accordance with a first embodiment of the present invention when carried on the backing of release material;
FIG. 2 is an elevational view of a label of FIG. 1 when carried on a backing of release material;
FIG. 3 schematically illustrates a method of manufacturing the labels of FIG. 1; and
FIG. 4 is a perspective plan view of a label in accordance with a second embodiment of the present invention.
DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, there is shown a succession of self-adhesive labels 2 in accordance with a first embodiment of the present invention when carried on a backing 4 of release material. As is shown more clearly with reference to FIG. 2, each label 2 comprises a support piece 6 which is self-adhesive, the support piece being coated on its rear surface with a layer of pressure-sensitive adhesive which is releasably carried on the backing 4 of release material. A major portion, apart from a transverse edge, of the upper surface of the support piece 6 is coated with a layer 8 of adhesive, such as a water-soluble or hot melt adhesive, and the layer 8 of adhesive adheres to the support piece 6 a muitilaminar label 10, such as a booklet. The layer 8 may be applied as extruded beads or as a whole surface coat. A self adhesive laminar material 12, such as a clear plastics material, has a self-adhesive rear surface and the laminar material 12 is adhered by its self-adhesive surface over the support piece 6 and the label 10 thereby to constitute the entire front surface of the label 2. A portion 14 of the laminar material 12 is adhered to the transverse edge 16 of the support piece 6 which is not covered by the label 10. At the other transverse edge of the label 2 the laminar material 12 includes an edge portion 18 which is adhered by its self-adhesive Surface directly to the backing 4 of release material. Referring again to FIG. 1, a corner of the edge portion 18 of the laminar material 12 is coated on its rearwardly-directed self-adhesive surface with a patch of ink 20. The patch of ink 20 extends as far as the free edge 22 of the lamina
