Label/leaflet assemblies

Abstract: A label/leaflet assembly includes a support web (10) with a release coating on which is placed an adhesive label (11) with a leaflet (12) secured on its front face. The leaflet has a front cover (13) one end (13a) of which extends beyond the underlying panels (16) of the leaflet. This end (13a) of the leaflet has a first part (22) which is permanently joined to the main body of the front cover (13) and which is releasably and re-sealably adherent by adhesive (23) to the label (11), and a second part (21) which is permanently secured by an adhesive (21a) to the label (11) and is connected to the first part (22) and/or the main body of the front cover (13) along one or more tear lines (20). Until opened the leaflet is held firmly sealed by the second part (21). When opened the leaflet is re-sealable, but the torn tear lines (20) show that the leaflet has been opened. The assembly is thus tamper-evident.

Description: This invention relates to label/leaflet assemblies and in preferred embodiments provides access to a leaflet on the label, permits the leaflet to be re-sealed on the label and provides visible indication if the leaflet has been opened. International Patent Application No. WO 88/02308 describes a method and apparatus for making labels. In particular a label is described which has an outer, and a primary inner, label member between which lie three secondary inner label members. The primary inner label member has its lower surface coated with adhesive which may be masked by a sheet of peelable release material prior to application to a product. The outer, and primary inner, label members extend longitudinally in both directions beyond the secondary inner label members and are joined together at both longitudinal ends beyond the secondary inner label members. British published Patent Application No. GB 2 213 428-A describes a leaflet, folded so as to conceal information printed on the leaflet, having a tear line running transversly across the folded leaflet from one lateral edge of the leaflet to another lateral edge. Located between the tear line and the transverse end edge of the leaflet closest to the tear line is a band of non-reusable adhesive, whilst on the other side of the tear line is located a band of reusable adhesive. According to this invention there is provided a label/leaflet assembly comprising a carrier web having a release coating on its front face, a label sheet having on its rear face an adhesive by which the label sheet is attached to the front face of the carrier web, a leaflet which is secured to the front face of the label sheet and which has a front cover sheet having a main body part overlying other sheets of the leaflet and an end edge portion extending beyond said other sheets, said assembly being characterised in that one or more areas of the end edge portion of the cover sheet are adhesively secured to the label sheet and are connected to adjoining parts of the end edge portion by a tear line or lines, in that the parts of the said end edge portion other than said area or areas are releasably and re-attachably attached to the label sheet, and in that said tear line or lines extend from a transverse end edge of said end edge portion to another edge of said front cover sheet, whereby when said end edge portion is torn along the tear line or lines, said one or more areas remain adhesively secured to the label sheet and the other parts of the end edge portion remain connected to the main body part of the front cover sheet. According to a preferred feature of the invention an adhesive is applied to the front face of the label sheet for releasably and re-attachably attaching said parts of the edge portion to the label sheet and for adhesively securing said one or more areas to the label sheet, said parts of the edge portion having thereon a coating which renders them releasably and re-attachably attached to the label sheet by the adhesive on the front face of the label sheet. According to another preferred feature of the invention said area or areas comprise one or both of two corner parts at opposite transverse ends of said end portion of the cover sheet. In one such construction in which the two corner parts constitute said areas, a part of the end portion between said corner portions has its end edge extending beyond said corner portions and unattached to the label sheet so as to provide a tongue or tab capable of being gripped by the fingers. Preferably said corner part or each of the corner parts is defined by a slit extending to a lateral edge of the cover sheet from a location adjacent such edge and by a tear line as aforesaid which extends from the inner end of the slit to the end edge of the cover sheet. The invention will now be described in more detail with reference by way of example to the accompanying diagrammatic drawings in which: Figure 1 shows a perspective view of a label/leaflet according to the invention, and Figures 2 and 3 respectively show plan and elevation views of a second embodiment of the invention. Each of the illustrated constructions comprises a carrier or support web 10 the front or upper surface of which is coated with a release material, a label sheet 11 having its rear face coated with an adhesive 11a by which the label sheet is releasably attached to the carrier web, and a leaflet 12 secured to the front face of the label sheet. The leaflet comprises a front cover sheet 13, a rear panel 14 connected to the cover sheet along a fold line 15, and one or more further panels 16 connected to the rear panel and to each other along fold lines, so that the further panels are disposed between the cover sheet and the rear panel. The rear panel is secured to the front face of the label sheet by a transverse line of adhesive 17 adjacent the fold line 15. Referring now particularly to Figure 1, the transverse end edge portion 13a of the cover sheet 13 remote from the fold line 15 extends beyond the folded sheets of the leaflet and beyond the folded sheets has two slits 18 extending parallel to the end edge 19 of the cover sheet to the respective adjacent lateral edges of the cover sheet from locations adjacent the lateral edges. A tear line 20 extends from the inner end of each slit 18 to the end edge 19 of the cover sheet and may be constituted by a broken line of cuts or slits. The two corner areas 21 of the cover sheet defined by the slits and the tear lines are secured to the underlying label sheet 11 by patches 21a of adhesive applied to the front face of the label sheet 11. The end portion 22 between the two corner areas 21 extends a short distance beyond these areas and is detachably and re-attachably attached to the label sheet by a line of adhesive 23 spaced away from the end edge, so that the portion 22 provides a tab or tongue to be gripped by the fingers. A series of such label/leaflet assemblies are disposed end to end on the web 10 and can be stored in the form of a reel until required for application to the products they are to identify. Application of the assemblies is conveniently carried out by automatic means in the well-known way, the web being passed round a roller of small diameter disposed at a station past which the products are fed in succession. The roller causes the label/leaflet assemblies to separate from the web and to become attached by the adhesive 11a to the products as the products pass the station. Subsequently, in use by the purchaser, the tab is pulled upward the cover sheet tears along the lines 20 to the slits 18 to give access to the leaflet. Subsequently the tab can be releasably re-attached to the label sheet by the line of adhesive 23 so as to re-seal the leaflet. The tearing along the lines 20 however provides a visual indication that the leaflet has been opened, which is desirable where the leaflet contains an offer or other content of monetary value or where there is a risk of the leaflet being tampered with. The corner areas 21 may be secured to the label sheet by a different adhesive from that used for the line 23, or by the same adhesive if the mating surfaces of the tab 22 are rendered impervious, as by a suitable lacquer or varnish, to penetration by the adhesive used in the corner areas. In a modified construction the parts of the corner areas 21 adjoining the slits 18 are left free of adhesive and the panels 14 and 16 of the leaflet extend so that their edges can be engaged under these parts of the corner areas prior to re-sealing. Figures 2 and 3 illustrate another form of construction according to the invention. In this form, the part of the label sheet underlying the end portion 13a has a transverse band of adhesive 34 and part of the portion 13a extends beyond the adhesive so as to form a tab or flap 35 which can be gripped to tear open the label/leaflet assembly. The tab 35 narrows adjacent the lower edge 36 of the leaflet and the underlying edge of the label sheet is shaped correspondingly. A broken line of slits 37 extends in a curve from the free edge of the end portion 13a across the band of adhesive to the bottom edge 36 of the portion 13a. Above this line of slits 37, the rear face of the portion 13a has a coating of a varnish or lacquer to which the adhesive 34 adheres detachably and re-sealably; but below the line, no varnish or lacquer is used and the adhesive forms a secure bond with the material of the front cover. To gain access to the leaflet, the tab 35 is grasped and pulled outward to detach the portion 13a from the adhesive 34 where the portion is coated with varnish or lacquer, but the part of portion 13a below the slits 37 is firmly adhered to the label sheet and in consequence portion 13a becomes torn along the line of slits 37. The front cover of the leaflet can subsequently be releasably re-attached to the label sheet by the adhesive 34, but the tearing along the line 37 provides a visual indication that the leaflet has been opened. The tear line or lines need not be weakened in the various constructions and need not be marked on the leaflet since in some cases they may be quite short and/or such as to be torn without the application of particular force. The constructions described and illustrated are also advantageous in that they overcome application difficulties associated with currently available resealable label/leaflets, which often spring open during application to the produce or during packing of the product, particularly under certain climatic conditions, e.g. of heat or cold. The permanently sealed part of the portion 13a and the tear line together hold the leaflet closed, but the leaflet can nevertheless be re-sealed after use.
