Description

SELF-ADHESIVE LABELS The present invention relates to self-adhesive labels. In particular, the present invention relates to multiple sheet construction self-adhesive labels, in which the label incorporates a bent leaflet or sheet to provide a large surface area for carrying printed information, which is larger than the surface area of the printed sheet. imprint of the label. The labels of the present invention have particular application in the labeling of pharmaceutical products. A variety of so-called printed sheet or flyer labels or booklet labels are known in the art and a typical label construction is described in U.S. Patent No. 5,399,403, in the name of David J Instance. In such labels, a folded printed sheet or individual booklet is supported on a base or self-adhesive support piece, which adheres itself removably to a release material holder. The folded printed sheet or brochure is often overlaminated with a clear plastic, self-adhesive layer. Such labels can be relatively expensive to manufacture due to the need to print substantially all of the text, apart from that on the basis by multiple color printing on a single sheet of relatively expensive coated paper that must be folded or formed later into a brochure or sheet printed or flyer. In addition, known labels may suffer from the disadvantage that when several versions of the same label construction are required that correspond to slight variations in the product to be labeled, it is necessary to have a separate printed sheet for each version of the label. This is relatively inefficient to manufacture, particularly for short manufacturing runs for labels, because this requires that parts of folded printed sheets or brochures be made to order or maintain a reserve of each label version. Finally, such labels are used to mark pharmaceutical products. To protect consumers of pharmaceutical products, it is essential that proper quality control is exercised to ensure that the correct folded sheet or brochure is placed with the correct underlying support piece. The present invention has as its main purpose to provide improved self-adhesive labels. More particularly, it is an object of the present invention to provide inexpensive printed leaf or flyer labels or brochure labels, particularly for multiple versions of commercial or short-run merchandise brands of the same label. A further object of the present invention is to provide a printed sheet label or multi-component flywheel having improved quality control characteristics to ensure proper manufacturing. The present invention provides a self-adhesive label comprising a self-adhesive base supported on a carrier of release material, a portion of multiple sheets placed on a first portion of the base, a layer of adhesive on a second portion of the base adjacent to the first portion, and a printed cover sheet having a first edge portion, which is adhered to the base by the adhesive layer, a central portion, which extends over the multiple sheet portion, and a second edge portion. Opposed to the first edge portion, which is arranged to be held against the release material holder to thereby retain the self-adhesive label in a closed configuration. The present invention further provides a multi-component self-adhesive label supported on a release material backing, the label comprises a self-adhesive base having a self-adhesive backwardly adhered surface removably attached to the release material backing and a printed upper surface, a portion of multiple sheets selected from the group consisting of a booklet and a printed sheet or folded flyer, the multiple sheet portion is placed on the upper surface of the base, a printed cover, which is adhered by a first portion of edge thereof to an edge portion of the upper surface of the base on a first side of the label, covers a surface. upper portion of the multiple sheet portion and, on a second side of the label opposite the first side, extends along the base and the multiple sheet portion to form a second edge portion thereof, which is secured to the support of the release material, the upper surface of the base and at least one surface of the cover are printed by a printing process with fabric or screen printing. The present invention still further provides a multi-component self-adhesive label supported on a release material backing, the label comprises as a first component, a printed self-adhesive base adhered by a subsequent self-adhesive surface thereof to the backing of the release material, as a second component, a portion of multiple sheets, printed, folded, placed on the base and as a third component, a printed cover for the portion of multiple sheets, which has an edge adhered to the base and a second edge secured to the base. release material adjacent to the base on the respective opposite sides of the multi-sheet portion, whereby the label adheres in a closed configuration and can be opened by pulling the second edge away from the release material, and wherein at least one of the base and the multiple sheet portion is provided with a printed code, the which can be inspected when the label is in the closed configuration. The present invention still further provides a self-adhesive label supported on a release material carrier comprising a multiple sheet portion, a cover having a central portion, which covers the multiple sheet portion, and a first and second edge portions. opposite on the respective opposite sides of the multi-lamella portion, the edge portions are adhered to a carrier of release material and the multi-layered portion is adhered to the central portion, and the first and second tearing lines separate the central portion of the respective edge portions, whereby the central portion adhered thereto, can be pulled away from the rest of the label, tearing along the tear lines. The embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a plan view, in perspective, of a self-adhesive label supported on a support release material, according to a first embodiment of the present invention; Figure 2 is a view from the bottom of the label of Figure 1, the rear surface of the label being seen through the transparent support of the release material; Figure 3 is an exploded section along line A-A of the label of Figure 1; Figure 4 is a plan view, in perspective, of a self-adhesive label supported on a release material support, according to a second embodiment of the present invention; Figure 5 is an exploded view along the label line B-B of Figure 4; Figure 6 is a plan view, in perspective, of a self-adhesive label supported on a support of release material, according to a third embodiment of the present invention; Figure 7 is an exploded view along line C-C of the label of Figure 6; Figure 8 is an exploded view along line D-D of the label of Figure 6; Figure 9 is a plan view, in perspective, of a self-adhesive label supported on a support of release material, according to a fourth embodiment of the present invention; and Figure 10 is a plan view, in perspective, of the label of Figure 9 after removal of the leaflet therefrom. In the drawings, the thicknesses of some of the layers have been exaggerated with the purpose of being clearer in the illustration. Referring to Figure 1, there is shown a self-adhesive label 2 according to a first embodiment of the present invention, when it is supported on a support 4 of release material. Typically, a succession of such self-adhesive labels is supported on an elongated web of the release material carrier 4 and the carrier 4 of release material is wound onto a reel in a known manner for automatic application of the labels to a succession of products. or containers to be labeled by a labeling machine. The self-adhesive label 2 comprises a self-adhesive base 6, typically made of paper or plastic, which is coated on its back surface with a layer of pressure sensitive adhesive, which adheres releasably to the support 4 of release material . A booklet 8 is deposited on a major portion 10 of the base 6 with the spine or back 12 of the booklet being separated from the transverse edge 14 of the base 6, so as not to cover a minor edge portion 16 of the base 6. The edge 18 of the booklet 8, which is opposite the spine or back 12, extends longitudinally along an opposite transverse edge 20 of the base 6. However, in an alternative embodiment, the edge 18 may be stopped before or coinciding with the transverse edge 20. A cover 22 has a central portion 24, which covers the booklet 8 and two opposite edge portions 26, 28. An edge portion 25 is adhered by a layer of adhesive 30 to the edge portion. smaller 16 of the base 6 and the other edge portion 28, is adhered by a second layer of adhesive 32 directly to the support 4 of the release material. A third layer of adhesive 34 is located between an upper surface 36 of the booklet 8, and a lower surface 38 of the cover 22 along the spine or back 12 of the booklet 8. In the illustrated embodiment, the first and third layers of adhesive 30, 34, are comprised of a permanent adhesive, typically a water-soluble adhesive, such as a PVA adhesive or a hot melt adhesive, which adheres together with base 6, booklet 8 and cover 22 together . The second adhesive layer 32 of the embodiment illustrated, comprises a release adhesive, such as a hot melt release adhesive, which is intended to be removably adhered to the product intended to be labeled. Thus, when the self-adhesive label 2 is adhered to a product to be labeled, for example, a pharmaceutical container, the label 2 can be opened to access the booklet 8. by pulling the edge portion 28 of the cover 22 of the product . In an alternative arrangement, the second adhesive layer 32 is a permanent adhesive and one or more perforation lines are provided. (not shown) through the cover 22 between the second layer 32 of the adhesive and the brochure 8, line or perforation lines, which can be torn when the label 2 is adhered to a product to have therefore access to the brochure 8. In an additional alternative arrangement, the major and minor portions of the base are interchanged, so that the brochure is placed over the smaller portion of the base and the cover sheet adheres to a larger portion of the base. In accordance with a particularly preferred aspect of the present invention, the self-adhesive label is provided with a number of security features to enable the integrity of the label to be verified. When pharmaceutical products are marked, it is essential, in order to minimize the risk exposure of the manufacturer's product, that the label be manufactured correctly. In multi-component labels, it is essential that, the label as a whole, combine the correct components. In accordance with this aspect of the present invention, a cut hole 40 that forms a window in the cover 22 can be provided through the edge portion 26 of the cover 22, which exposes a code 42 printed on the top surface 44. of the base 6. In this way, a user or purchaser of the self-adhesive label 2 can verify that the self-adhesive label 2 incorporates the correct base 6. Furthermore, as shown in Figure 2, the holder 4 of the release material, It is composed of a transparent plastic cloth. Accordingly, the back surface 48 of the self-adhesive label 2 can be easily inspected, either visually or automatically. The provision of the edge 18 of the booklet 8 extending along the transverse edge 20 of the base 6 reveals an exposed portion 50 of the rearmost sheet 52 of the booklet 8. The exposed surface 50 and the rear surface 54 of the base self-adhesive 6, can each be printed with a respective code 56, 58, in the illustrated embodiment, the codes 56, 58 are bar codes. The bar codes 56, 58 can be scanned, either visually or automatically to make sure that the correct booklet 8 is associated with the correct base 6. Referring to Figure 3, the different components of the sticker 2 are shown in separate form. The self-adhesive base 6 adheres removably to the support 4 of the release material. A succession of self-adhesive bases 6 can be formed on a length of the support 4 of the release material, providing a material web, for conventional labels, comprising a self-adhesive fabric supported on a support of release material, printing a succession of images on the upper surface of the self-adhesive fabric, die-cut the self-adhesive fabric to form a succession of labels supported on the release material support, and then remove the matrix of the residual material surrounding the labels. After such a process, the bases 6 can be provided with a desired printed image on the upper surface 46 of each base 6. Each booklet 8, comprises a plurality of printed sheets, and has been applied to a respective base 6. The sheet of cover 22 may be composed of any suitable material, such as paper or plastic. Both the front surface 60 and the back surface 62 of the cover 22 can be printed with the desired images. A printed fabric for forming the cover sheets is adhered by means of the adhesive layers on the booklet / base mounts. The resulting fabric is cut with a matrix to form the required labels and the residual fabric matrix is removed. In a particular arrangement, the cover 22 may be transparent plastic, optionally printed on one or both surfaces thereof. In such an arrangement, there is no need to cut with a matrix a window through the cover 22, such as the window 40 in Figure 1. Instead, the underlying code 42 can be simply revealed through the transparent cover, optionally through an unprinted window formed by printing around a solid opaque layer over the top or rear surface of the roof. The front surface 64 of the self-adhesive label 2 essentially comprises the printed front surface 60 of the cover 22. Thus, in accordance with the present invention, it is possible to print only the cover 22 to be printed with high-quality multi-color images. , by means of a process of printing with fabric or screen printing, for example by flexography. High quality multi-color images can also be printed on the upper surface 46 of the base 6 by a cloth printing process, such as flexography. The rest of the label 2, which comprises the brochure 8 as the larger printed portion of the label 2, can be printed with a lower quality single color print and a lower quality paper without damaging the overall initial appearance of the label . This can lead to a reduction in label costs. 2. The brochure may have been printed as a sheet or sheets and folded and formed into a brochure. In addition, when it is intended to print the label 2 in a number of different versions with slight variations, for example, when label 2 is intended to label a range of pharmaceutical products, the front surface of the base and the front surface of the cover they can be printed with information specific to the version, such as information related to the number and dosage of a tablet for a particular pharmaceutical product, and the booklet can be printed with common information for each version of the label. Thus, for a number of label versions, only one printed brochure may be required. This increases the efficiency of label production. The multi-component structure of the label consisting of the cover, which can be printed on its front and back surfaces, the booklet and the base, which can be printed on its front surface, can effectively simulate a page booklet. Multiple s has a greater number of pages than the actual brochure placed on the base's label. Thus, on the resulting label, the label can simulate the printed area of, for example, a 12-page booklet attached to the product, while the booklet itself has only eight pages. This allows thinner booklets to be used, making the booklet easier to fold and manufacture and, for the manufacturer of the product that automatically applies the labels on a packaging line, facilitating its use. The label, in that and other modalities, can be modified by using a folded sheet or sheet instead of a brochure. The third layer of adhesive can be located between the base and the backmost leaf of the booklet. The printing on the base and on the cover sheet can be cured using UV radiation. In addition, the printing on the cover sheet can be coated with a varnish layer to provide rub resistance. One or more openings may be left in the varnish layer, to allow printing on the upper part of the sheet by hot stamping, laser printing or thermal transfer. In addition, the bases may comprise a continuous integral basis for each label in place * of first and second base portions for each label. Referring to Figures 4 and 5, there is shown a second embodiment of a self-adhesive label 70 supported on a support 72 of release material according to the present invention. In this embodiment, a self-adhesive base 74 has been placed on a booklet 76 and a cover 78 was adhered by means of a layer of adhesive 80 to a transverse edge 82 of the base, which extends over the leaflet 76 and adhered to the support 72 of the release material as in the first embodiment. In this embodiment, the transverse edge 84 of the cover 78 was adhered via a second layer 86 of adhesive to a self-adhesive transverse support strip 88 comprised of the same material as the base 74. The entire label 70 was overlaminated with a plastic sheet material, self-adhesive, transparent, 90, which protects the label against unintentional damage and improves the aesthetic appearance of the label. A pair of perforation lines 92 extend through the sheet material 90 and the cover 78 at a position located inward of the second adhesive layer 86. When the label 70 adheres to a product and a user wishes to open it, access can be gained to the booklet 76 tearing along the perforation lines 92. A third layer of adhesive 94 adheres the booklet 76 in the vicinity of the spine or back 96 of the cover 78. An additional perforation line 98 extends through the sheet material 90 and the cover 78 and is positioned between the second and third adhesive layers 80, 94. The perforation line 98 may extend through the base as well. After a user has opened the label by tearing along the perforation lines 92, the central portion 100 of the cover 78 and the underlying booklet 76 adhered to it, can be removed from the underlying base 74 by tearing along the perforation line 98. The self-adhesive label of Figures 4 and 5 can be modified by omitting the plastic sheet material. Figures 6 to 8 illustrate a label according to a third embodiment of the present invention. In this embodiment, the label of the second embodiment was modified by omitting the second adhesive layer and the underlying self-adhesive support part and by matrix cutting the free transverse edge of the cover sheet, to provide a detachment tab and adjacent to it , a self-adhesive surface exposed to the back of the sheet material, which adheres directly to the release material holder to thereby maintain the label in a closed configuration. The resulting label is resealable and drilling lines can be omitted. More particularly, the self-adhesive label 102 comprises a self-adhesive base 104 supported on a support 106 of release material. A booklet 108 is placed on the base 104 and a cover sheet 110 is adhered by a first layer of adhesive 112 to a transverse edge 113 of the base 104 and by a second layer 114 of adhesive to an upper surface 116 of the booklet. 108, along the spine or back 118 of the brochure 108. The cover sheet 110 is provided at its free transverse edge 120 opposite the other transverse edge 122, which is adhered to the base 104, with a cut edge 124 The die-cut edge 124 defines on a longitudinal edge 126 of the label 102, a detachment tab 128. A self-adhesive, transparent plastic sheeting 130 is adhered by means of its self-adhesive surface on the cover sheet 110. The sheet material 130 extends along the die cut edge 124 e the cover sheet 110, at a location transversely adjacent the release tab 128 to form an edge portion 132 thereof, which a self-adhesive surface exposed to the rear 134, which adheres directly to the support 106 of the release material. When the label 102 is adhered to a product, a user can manually pull the release tab 128 thereby pulling the edge portion 132 of the sheet material 130 away from the product to open the label 102. After the booklet 108 has After being read by the user, the label 102 can be returned to its closed configuration by reworking the edge portion 132 of the sheet material 130 back onto the surface of the product. A further embodiment of a self-adhesive label according to the present invention is illustrated in Figures 9 and 10. In this embodiment, the self-adhesive label 150 is specifically configured to be used as a label for labeling pharmaceutical products, in which a drug, for example an antibiotic, in a container labeled with the label 150, to a pharmacist. The pharmacist uses a portion of the label to assist the pharmacist in the distribution of the drug, portion of the label that is removed by the pharmacist and then the container for the drug, with the remaining portions of the label attached thereto, is given to the pharmacist. patient to whom the drug has been prescribed. As shown in Figure 9, the self-adhesive label 150 comprises a self-adhesive base 152, which is supported on a support 154 of release material. As in the embodiment of Figure 1, a booklet 156 is placed on the base 152 and in turn a cover 158 is placed on the booklet 1561. An edge 160 of the cover 158 adheres to a corresponding edge 162 of the base 152 by means of of a first adhesive layer 154 and an opposite edge 166 of the cover 158, is adhered by means of a second layer of adhesive 168 to a second base 170, which is separated from the first mentioned base 152. In alternative configurations, the base 152 and the second base 170 are integrated or the second base 170 is omitted. The spine or back 172 of the booklet 156 adheres to the rearwardly directed surface 174 of the cover 158, by means of a third layer of adhesive 176, which is located along the spine or back 172 on the top sheet 178 of the brochure 156. The layers 164, 176 of the adhesive are separated in the longitudinal direction of the support 154 from the release material and are located between a substantially V-shaped tear line 179. The layer 164 substantially covers the entire back surface of the edge 160, or adhesive points are alternatively provided between the tear line 179 and a linear band of adhesive 164. The tear line 179 diverges outwardly from a portion located transversely at the center 180 of the cover 158. The line of tear 179 is provided with a central tab portion 182 and a pair of slanting series lines, inclined, 184, 186, extending from the central portion 180, towards the respective longitudinal edges 188, 190 of the cover 158. An additional tear line 192 is provided on the cover 158 between the booklet 156 and the second adhesive layer 168. The second tear line 192 comprises a series of V-shaped cuts of 194, which extend in a line transversely through the cover 158, with the vertices 195 of the V-shaped cuts 194 pointing towards the second layer of adhesive 168, and a series of cuts linear 197 adjacent the second adhesive layer 168. As shown in Figure 10, in use, the label 150 adheres to a product 196 to be labeled.
