Description

LABELS AND MANUFACTURE THEREOF}

Producers producing consumer goods sometimes seek to promote the sale of their products using so-called "immediate winning" promotions. In such promotions, a number of products are provided, directly or indirectly, with hidden information presented by the user who can claim the prize if the product is identified as a prize. Many products are identified as non-winnings, and only a few are identified as winnings. Information indicating whether a product is a winning or non-winning item must be virtually inaccessible until the user purchases the product and a trace of tampering as a result of the user's accessing the information. For example, typical instant winning promotions include inserting a winning ticket into a sealed product pack, printing information inside a metal can, and printing a so-called scraping promotional product on the product packaging. All of these promotions require a substantial modification of the packaging or labeling requirements of the product.

The present invention relates to self adhesive labels and methods of making such self adhesive labels. In particular, the present invention relates to a label that does not reveal folded and hidden information and can be opened by a user when attached to a product to reveal previously hidden information.

The present invention is in the form of a self-adhesive label showing a secure, open trace that can be affixed to the product as a secondary label, wherein the primary label provides an instant winning promotion system that conveys standardized information related to the product to the consumer. For that purpose.

Secondary labels in the form of single labels have been used for many years for consumer use. Such labels may be provided with perforations on the front cover, for example, as disclosed in EP-A-0043179, or with labels superimposed on one another, as disclosed in EP-A-0180365. Such conventional sheet-shaped labels are not suitable for use as instant winning promotion labels because they do not provide any security with respect to the opened trace.

Another object of the present invention is to provide a self-adhesive label suitable for use as an instant winning promotion label that provides the desired safety and clear opening traces.

Accordingly, the present invention is a self-adhesive label attached to the rear side of a release, having a self-adhesive support having a rearward facing self-adhesive surface attached to the rear side of the release, and disposed over the front side of the support, the front cover and the rear side. The folded part including the cover and the intermediate part surrounded by the cover and the folded part attached to the folded part to cover the folded part, extending beyond the edge of the support piece and the folded part and sticking well to the back of the release. It consists of a laminated material that forms a peripheral boundary of a label with a back facing surface to which the adhesive has been applied, the middle portion of which provides access to the adhesive by cutting or tearing the laminated material.

In addition, the present invention is a method of continuously producing a self-adhesive label attached to the back of the release, (A) provides a self-adhesive support web attached to the back of the release, (B) the front cover portion, the back The sheet is cut from any of the folded sheets by continuously attaching the folded sheet consisting of the cover portion and the intermediate portion therebetween along the support web, and (c) die cutting the folded sheet and the support web assembly up to the release. Continuously cut intermediate labels, each consisting of a folded sheet attached to a support piece cut from the support web, (d) remove the waste surrounding the intermediate label from the back of the release, and (e) each intermediate label Web and intermediate las made of self-adhesive laminated material coated with an adhesive that adheres well to the press so that it can be enclosed by the laminated material. Superimposing the bells and (bar) die cutting through the lamination material around each intermediate label to form a perimeter boundary of the redistributable material surrounding each intermediate label and attached to the back of the release. It provides a self-adhesive label production method.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 and 2 show a self-adhesive label 2 according to an embodiment of the present invention with a release, for example, attached on a web of the back side 4 of a silicone coated paper. In general, a series of such labels 2 are attached on the back 4 of the release and are wound on a reel for automatically attaching the self-adhesive label 2 to the product to be labeled by an automatic label applicator. .

The self-adhesive label 2 is typically made of a transparent plastic, such as polyvinyl chloride, polyester, polyethylene or polypropylene, on the back side of which the support piece 6 can be released on the front surface of the back side 4 of the release. It comprises a lower self-adhesive support piece 6 composed of a sheet 8 to which an adhesive layer 10 is applied, which is easily pressed evenly by pressing. In the label (2), the folded sheet 12 has a back cover 14, a front cover 16 folded over the back cover 14 about the first fold line 18, a front cover 16 and It consists of an intermediate panel 20 which lies between the rear covers 14 and is connected to the rear cover 14 by a second fold line 22. The back surface of the back cover 14 is attached to the main part of the front side of the support piece 6 by means of a permanent adhesive layer 24, typically an aqueous adhesive layer such as PVA adhesive. The front cover 16 includes an extension flap 26 extending beyond the second fold line 22 and disposed adjacent to the front side of the support piece 6.

The front cover 16 of the self adhesive label 2 hides the printed information on the surface of the intermediate panel 20. When the self-adhesive label 2 is used in an instant winning promotional item, such hidden printed information may include an indication indicating whether the label is a winning or non-winning label.

The support piece 6 and the folded sheet 12 extend in the longitudinal direction of the folded sheet 12 and the web of the back side 4 of the release, ie between the first fold line 18 and the extension flap 26. Direction is dimensioned, and the support piece 6 extends longitudinally beyond the first fold line 18 and the extension flap 26 so that two opposing edge portions not covered by the folded sheet 12. To form (28, 30). The second portion 30 is longer in the longitudinal direction than the first portion 28 and is located on the side of the folded sheet 12 that is opened by the user. As will be described below in connection with the method of making the self-adhesive label 2, the opposite transverse edges 32, 34 of the folded sheet / support assembly are folded sheet 12 and support piece 6 formed by die cutting. Include edges that match.

The folded strip / support assembly is preferably laminated and composed of a transparent plastic sheet, such as polyvinyl chloride, polyester, polyethylene, or polypropylene, which is applied with an adhesive layer 40 that adheres well to the pressing surface. It is completely surrounded by the self adhesive laminate material 36. The adhesive that sticks well even when pressed is a conventionally known permanent adhesive. Certain permanent adhesive formulations are selected to form a strong and reliable adhesive bond to the surface of the particular product to which the label is to be attached. The laminate material 36 extends longitudinally beyond the edges 28, 30 of the support piece 6 and extends laterally beyond the horizontal edges 32, 34, thereby surrounding the folded sheet / support assembly. And a boundary 42 is attached to the back side 4 of the publication by means of an adhesive layer 40 which all the periphery presses well. In FIG. 1, the laminate material 34 is transparent, so that the folded sheet / support piece assembly disposed thereunder is visible to the naked eye.

The laminate material 36 is attached to the front surface of the front cover 16 and the front surfaces of the two opposing edges 28, 30 of the support piece 6 by means of an adhesive layer 40 which, by pressing, adheres well.

The self-adhesive label 2 is provided with an open line 44 which extends transversely across the label 2, in particular across the extension flap 26. Opening line 44 includes a printed line indicating that label 2 should be cut open. Such a construction is used when a label must be attached to a cuttable substrate of a product, for example a plastic packaging film. Otherwise, the opening line 44 may consist of a perforated line that extends through the stacking material 36 and the extension flap 26 when the label is to be attached to a thick, rigid substrate, such as a box or container. have.

In use, the self-adhesive label is attached to the labeled product and permanently attached to it by the self-adhesive boundary 42 and the self-adhesive support 6. Since a strong adhesive bond is made between the label 2 and the product, the self-adhesive label 2 is not accidentally opened. Since the laminate material 34 completely surrounds the folded sheet 122, there is no risk of the folded sheet 12 being accidentally accessed by the user. In particular, because the border 42 extends outward along the die cut transverse edges 32 and 34 of the folded sheet / support piece assembly, the label is secured even when trying to access the printed interior surface of the folded sheet 12. It is not possible to look into the body of the sheet through these horizontal edges before opening it.

The adhesive that adheres well to the pressing of the stacking material 34 has a permanent adhesive bond on the surface of the particular product to which the label is to be attached so that the self-adhesive label (2) is removed from the product until it is cut or cut along the opening 44. It is chosen so that it cannot be easily peeled off or opened. This reduces the incidence of attempting to open a label before purchasing a product to confirm whether the product is a winning or non-winning product. Thus, the label 2 may provide a feature that shows an open trace that can only be opened by a cutting or cutting device.

After the laminate material 36 and the extension flap 26 have been cut or ruptured, the intermediate panel 20 can be manually accessed to pull the intermediate panel outward from the pocket defined by the front and rear covers 16, 14. have. In this way, the user can reveal the hidden information previously printed on the middle panel 20, for example, to confirm whether the product is the winning product of the instant winning promotion product.

A method of manufacturing a self-adhesive label according to the embodiment of FIGS. 1 and 2 is illustrated in FIGS. 3 and 4.

In Figure 3, a series of folded sheets are attached to a support web that lies on the back of the release, and the sheet and bottom support web that lies on the back of the release are die cut and laminated by a web of self adhesive laminate material. The apparatus, indicated by reference numeral 50 for carrying out the first stage, is shown. 4 shows a second stage of the method in which a stacked assembly of die cut folded sheet / support piece assemblies is placed in a second die cutting step and the self-adhesive label of the first embodiment is formed and wound onto a reel of the release; It shows the device to perform.

Referring to FIG. 3, there is provided a reel 52 of a press-fitted duplex material consisting of a transparent plastic web 54 that adheres well onto a back web 56 of a release. . The duplex web is released from the reel 52 and transported past the adhesive application station 58, where the adhesive applicator 60 carries a series of liquid adhesive patches 62, e. 54 along the length of the upper surface. The duplex web is then transferred to the folded sheet application station 64, where a series of folded sheets are applied to the continuous adhesive patch 62 by a sheet applicator represented by the lamp 58. The folded sheet 66 is applied together with the adhesive patch 62 such that the back cover of each folded sheet 66 is attached to the plastic web 54 by each adhesive patch 62.

Folded sheet 66 attached to plastic web 54 is transferred to die cutting station 68. The die cutting station 68 is provided with an upper die cutting roller 70 and a lower support roller 72 through which a duplex web for supporting the folded sheet 66 passes. The die cutting roller 70 is designed to cut through but not pass through the back side 56 of the release to cut the folded sheet 16 and the support piece 6 attached to the release of the embodiment of FIGS. 1 and 2. Without it, the bonded folded sheet 66 is cut and the plastic web 54 is cut. This forms a series of intermediate labels 78. The waste material surrounding the intermediate label constituting the cutout armature of the plastic web of laminated material 54 supporting the cutout portion of the folded sheet 66 attached thereto is removed from the backside 56 of the release and reel 76 A waste web 74 is wound around it.

The die cut intermediate label is transferred to the lamination station 80, where the self-adhesive transparent plastic lamination material 82 is wound from the reel 84 and a series of intermediate labels on the back 56 of the release. Laminated by roller 86 from above. Each intermediate label 78 is completely surrounded by a stack of material 82 extending beyond the longitudinal and transverse cutting edges of the intermediate label 78. The resulting successive laminated intermediate label 78 is wound on a reel 88.

The second stage of the method is illustrated in FIG. 4. The assembly of lamination intermediate label 98 is conveyed out of the reel 88 to a second die cutting station 90 consisting of an upper die cutting roller 92 and a lower support roller 94. The die cutting roller 92 cuts only the lamination web 82 so that the outer periphery of the lamination material 36 of the embodiment of FIGS. 1 and 2 can be cut. The resulting waste web armature 96 is wound on a reel 98. This die cutting step forms the resulting self-adhesive label 2 of the embodiment illustrated in FIGS. 1 and 2. If the opening line 44 is a perforated cut line, it can be cut by the die cutting roller 92. The back side 56 of the release on which the self adhesive label 2 is supported is wound on the reel 100.

In the method of the present invention, each folded sheet 66 may be cut to form a plurality of folded sheets 16 spaced transversely across the web, and the plurality of self-adhesive labels 2 Die cutting may also be made to be provided over the width of the back side 56 of this release. The back surface 56 is broken up to form a plurality of reels (100).

In the drawings, for the sake of clarity, the thickness of a portion of the layer of the label is shown to be exaggerated.

In the illustrated embodiment, the self-adhesive label consists of a folded sheet with three panels. According to a variant of the invention, multiple panels may be provided.

According to the present invention, a sheet of self-adhesive label having sufficient security to construct an instant winning promotion label can be manufactured nicely, simply and easily. Providing a laminated label increases the security of the label, preventing the label from being accidentally opened and preventing the label from being opened without permission. The laminate material provides high precision physical protection to the underlying folded sheet of paper. According to the invention, there is no need to significantly change the product packaging or product packaging line. According to the present invention, there is a risk of inadvertently scratching the scratched area when handling the product, which requires a special printing device and ink and does not need to scrape a label that is not actually suitable for application to a labeled product.
