Description

-1 Self-adhesive label and method of making self-adhesive labels

Technical field

The invention relates to self-adhesive labels and to a process for their production. In particular, it relates to such labels which are folded or folded (hereinafter: folded) and obscure the hidden information and which are openable by the user when glued to the product to reveal previously hidden information.

BACKGROUND OF THE INVENTION

Consumer product manufacturers sometimes wish to promote products with so-called instant win advertising. In such events, a large number of products are provided, either directly or indirectly, with hidden information revealed by the consumer, and the consumer may then claim a prize if the product is designated as a winning product. A large number of products are labeled as non-winning products and a small number of products are labeled as non-winning products. Information indicating whether or not a product is a winning product should be substantially inaccessible until the consumer has purchased the product and be accompanied by evidence that tampering and unauthorized access to the information has not occurred. For example, typical instant-win advertising actions consist of inserting winning tickets into sealed product packages, printing information on the inside of metal cans, or fitting information with a so-called scratch layer on the surface of the package. All these procedures require a substantial change in the packaging or labeling requirements for the product.

Secondary labels in the form of leaflet labels have been known for many years for consumer purposes. Such labels • · ♦ 4 * 4 · ·

DETAILED DESCRIPTION OF THE INVENTION

Figures 1 and 2 show a self-adhesive label 2 according to the invention carried on a backing web 4 forming a label removal carrier (hereinafter: a take-off carrier), for example of silicone coated paper. On the substrate belt 4 is carried a sequence of such labels 2, which is wound into a roll for automatic application of self-adhesive labels 2 on products to be labeled by a self-labeling machine.

The self-adhesive label comprises the lowest backing member 6 comprising a sheet 8, preferably of a transparent plastic such as PVC, polyester, polyethylene or polypropylene, coated on the back with a layer of pressure-sensitive adhesive which releasably adheres the backing member 6 to the face of the pickup. the label comprises a folded back cover 14, a front cover 16 folded over the cover 14 around the first fold line 18, and an intermediate sheet portion 20 lying between the front and back covers 16, 14 and attached to the back cover 14 in the second fold line 22. Back surface The backsheet 14 is glued to the main face of the backing member 6 by a layer 24 of permanently adhesive, typically aqueous, adhesive, such as a PVA based adhesive. The faceplate 16 comprises an elongate flap 26 that extends across the second fold line 22 and lies adjacent the face of the support member 6.

The face cover 16 of the self-adhesive label 2 covers all the information printed on the surfaces of the intermediate sheet section 20. When the self-adhesive label is used within the recalm • 4 • 499 · · · · 9 · 4

instant win action, such hidden information may include an indication of whether or not the label wins.

The support member 6 and the folded leaflet 12 are sized such that in the longitudinal direction of the take-off carrier 4 and the folded leaflet 12, i.e. in the direction between the first fold line 18 and the extended flap 26, the support 6 extends over the first fold line 18 and the extended the flap 26 so as to form two opposite edge portions 28, 30 which are not covered by the folded leaflet 12. The second portion 30 has a greater length in the longitudinal direction than the first portion 28 and lies on the side of the folded leaflet 12 that is opened by the user. As described below with reference to the method of manufacturing the self-adhesive label 2, the transverse edges 32 are facing each other. 34 of the composite leaflet and support assembly formed by the same edges of the composite leaflet 12 and support member 6 have been formed by punching.

The folded leaflet and carrier assembly is sealed and completely encapsulated with a self-adhesive overlay 36, preferably consisting of a sheet of transparent plastic, typically PVC, polyester, polyethylene, or polypropylene, coated with a pressure-sensitive adhesive layer 40 on the reverse side. The pressure-sensitive adhesive is a permanent adhesive as known in the art. The particular composition of the permanent adhesive is selected so as to obtain a strong reliable adhesive bond with the surface of the particular labeled product. The tape 36 extends in the longitudinal direction over the edge portions 28, 30 of the support member 6 and in the transverse direction over the transverse edges 28, 30 to form an edge 42 surrounding the folded leaflet and support assembly, the edge 42 glued around its periphery to the base strip 4 of the removal carrier with a layer of adhesive

-Sensitive to pressure. In Fig. 1, the sticker is shown as transparent, with the folded leaflet and support assembly shown below.

The adhesive 36 is adhered by a layer 40 of pressure-sensitive adhesive to the face of the housing 16 and to the faces of two mutually opposed edge portions 28, 30 of the support member 6.

The self-adhesive label 2 is provided with an opening line 44 extending across the label 2 and in particular over the extended flap 26. The opening line 44 may be a printed line indicating where the label 2 should rupture, such arrangement being used when the label is to be adhered. to a breakable substrate, such as a plastic wrapping film. Alternatively, the opening line 44 may be formed as a perforated tear line passing through the overlap 36 and the extended flap 26 when the label is to be adhered to a thick or solid substrate, such as a box or container.

In use, the self-adhesive label is adhered to the article to be labeled and permanently adhered thereto by the self-adhesive edge 42 and the self-adhesive carrier 6. This ensures a strong bonding between the label 2 and the product so that the label 2 does not accidentally open. Since the overcoat material 34 completely encapsulates the folded leaflet 12, there is no danger that the folded leaflet 12 becomes randomly accessible to the user. Since the edge 42 extends outside the aligned transverse edges 32, 34 of the folded leaflet / carrier assembly, it is not possible for a person wishing to access the inside of the folded leaflet 12's printed surfaces through the cross-section without directly opening the leaflet. label.

The pressure-sensitive adhesive provided with the overlap 34 is selected to provide a permanent adhesive bond to the surface of the article to be coated so that the self-adhesive label 2 cannot easily peel off from the article or open without cutting or tearing open line 44. This reduces the risk of someone trying to open a label without buying a product to determine whether the product is a winning or a non-winning product. Thus, the label 2 may provide a feature of the tampering indicator since it is openable only by the cutting or tearing mechanism.

After the tab 36 and the elongated flap 26 have been cut or torn, manual access to the intermediate tab 20 and pulling the intermediate tab out of the pocket delimited by the face and back covers 16, 14 is allowed. printed on the intermediate pad 20 whether the product is a winning product.

1 and 2 is shown in FIGS. 3 and 4.

FIG. 3 illustrates a device 50 for carrying out a first phase of the method in which a sequence of folded or folded leaflets is adhered to a support belt carried on a support belt, followed by the leaflets and the underlying support belt supported on the support belt; They are cut to form a succession of intermediate labels which are then sealed with a web of self-adhesive stick-on material.

8 according to the first embodiment, and are wound into a coil in which they are supported by a backing sheet forming a take-up carrier.

In particular, Fig. 3 shows a double belt roll 52 comprising a transparent plastic belt 54 carried on a backing belt 56 forming a take-up carrier. The double web is unwound from the roll 52 and is passed around the glue application station 58 to which the glue applicator 60 applies a succession of liquid adhesive coatings 62 along the length of the upper surface of the plastic web 54. The double web is then transported to the folding station 64 wherein the sheets 66 are deposited with a leaflet applicator 68 on a sequence of flat glue layers 62. It will be appreciated that these pleated sheets 66 are deposited against the glue layers 62, so that the back cover 67 of each pleated sheet 66 is adhered to the plastic web 54 by corresponding plots 62.

The folded sheets 66, glued to the plastic web 54, are then conveyed to the cut-out station 68. The cut-out station 68 is provided with an upper cut-out roller 70 and a lower support roller 72 between which a double belt carrying the folded sheets 66 passes. blades 66 and cut the double waist 54 up to the backing sheet 56 of the release carrier material without, however, cutting it, so that the carrier 6 and the leaflet 16 adhered thereto are cut out according to the embodiment of Fig. 1a. This creates a sequence of label blanks 78. the material surrounding the label blanks 78 and consisting of a cut-out carcass of a plastics sheet of adhesive material carrying cut-out portions of the folded sheets 66 adhered thereto and thereby forming a waste belt 74 is removed from the carrier web 56 and wound into a roll 76 .

The cut label blanks 78 then advance to a stitching station 80, on which a strip of self-adhesive transparent plastic sticky material 82 is unwound from a corresponding roll 84 and is sealed by means of a roller 86 over a sequence of labels on the backing strip 56 of the pickup carrier. Each label blank 78 is completely encapsulated with a overwrapping material 82 that extends over both the longitudinal and transverse cut edges of the labels 78. The resulting sequence of overwrapped label blanks 78 is then wound into a roll 88.

The second stage of the process is illustrated in FIG. 4, in which a plurality of sticky label blanks 78 are unwound from their roll 88 and conveyed to a second cutting station 90 comprising an upper cutting roller 92 and a lower backing roller 94. The cut-out cutting roller 92 is only the overlapping strip 82, so that it cuts out the outer perimeter of the overlapping material of Figure 1a. The resulting waste skeleton 96 is wound into a roll 98. The resulting self-adhesive labels 2 of the embodiment of Figure 1a are formed. line 44, a perforation tear line, may be formed by a cutting roller 92. A backing web 56 carrying self-adhesive labels 2 is wound into a roll 100.

In the method of the invention, each folded sheet 66 may be cut to form multiple folded leaflets separated from each other across the strip, and the cut may be performed to form across the backing web 56 of the carrier material, wherein the backing web 56 is cut to form multiple coils. 100 ALIGN!

It will be apparent to those skilled in the art that they are shown in the drawings

-10the thickness of some label layers is greatly exaggerated for clarity purposes.

In the embodiment shown, the self-adhesive label comprises a folded leaflet with three tabs. In alternative embodiments of the invention, a plurality of facets may be formed.

The self-adhesive label according to the invention comprises an elegant, simple and easy-to-produce leaflet exhibiting sufficient security to produce an instant win label in a promotional event. The sealed label not only provides a measure of the security of the label, preventing it from inadvertently opening, and discouraging unauthorized opening of the labels by humans, but the label also provides a high level of physical protection for the underlying folded paper leaflet. The invention eliminates the need for significant changes in the firing of products or on the packaging line. The invention also eliminates the need for wiping labels that require a special printing machine and ink and are not suitable for use in product labeling because the wiping pads of the article to be labeled may be inadvertently scaled or scraped during handling of the article.
