Description

The invention relates to a sealing label for a closure.

Closure labels are known in the art. For example, this is in AT 09365 U1 sealing label also suitable to adhere to structured or on an unsuitable bonding reason that does not provide a complete bond area. The problem is solved by a two-layer pressure build-up. The seal label has a bottom layer that forms a complete bond surface for an upper void label.

In the GB 2 192 606 A For example, there is known a closure label for a closure which is 3-ply and is formed from a double folded strip. By opening the closure, two perforated strips are irreversibly ruptured.

From the US 2014/0167401 A1 is a closure label for the closure of a bottle with two Void Erstöffnungsnachweisen known, which are interconnected by means of a bridge section. One Void Breech Hole Certificate is attached to the bottle and the other Void Breech Hole Certificate is attached to the bottle cap. A disadvantage of the Void Erstöffnungsnachweis, which is attached to the closure, is the fact that closures often have a relief-like surface and the Erstöffnungsnachweis does not open over the entire surface exactly and therefore readable information can be accommodated only problems in the Erstöffnungsnachweis.

In the DE 10 2008 016 624 A1 discloses a sealing film for a bottle cap. In this case, the carrier film of the sealing closure is stretched to contract under heat treatment and to adapt to the surface shape of the bottle closure. Again, there is the problem that in the uneven surface does not cause a first opening detection in the form of a void effect over the entire surface exactly.

Furthermore, prior art void labels are made, for example DE 10 2012 218 033 , known. In this case, a multi-layered structure is provided, and the void label can be opened by peeling off a carrier layer with a part of the label from a part of the label remaining on the product. The peeling breaks a color layer, and information such as a code or the like becomes visible.

The disadvantage of this, however, is that the lower layer must adhere to the entire surface of the substrate, otherwise the separation of the ink layer does not take place over the entire surface and then possibly the code is not completely readable. This is problematic in relief-like surfaces that do not allow full-surface bonding.

The object of the present invention is to provide a sealing label which avoids the above-mentioned disadvantages.

The object is achieved by a sealing label having the features of claim 1.

The sealing label according to the invention is intended for sealing a closure which has a first closure part and a second closure part. The first closure member and the second closure member are movable relative to each other, for example, a bottle cork and a bottle neck, a perforated tear tab, and a paper box or can having a tear area. However, other embodiments of a closure are also conceivable. The concept of closure is here to be understood and understood very far.

The sealant label includes a first tamper evidence and preferably a second tamper evidence. The first and the second opening proof are independently triggerable. The first tamper evidence serves to reveal covert information, and the second tamper evidence serves to detect the first opening of the closure.

The sealing label according to the invention comprises an outer label layer and an inner label layer, which overlap in regions in contact with one another, at least as long as the sealing label is still sealed. The two label layers form over the overlap area the first opening inspection.

The first opening proof does not have to be limited to the overlapping area. The first first opening detection can be arranged in the overlapping area and additionally also extend to a contact area in which the outer label layer is arranged directly on a surface of the closure, preferably the first closure part, preferably glued. The first opening proof extends over areas of the inner label layer and over areas of the surface of the closure and is therefore particularly safe.

The first first opening detection extending over at least a region of the overlapping area, preferably the entire overlap area, comprises a color layer which breaks open on initial opening above the overlapping area. The color layer preferably extends over the entire overlap area, preferably down to the information area. The ink layer breaks up in fractures perpendicular to the plane of the label, with portions of the ink layer adhering to one and other portions of the ink layer on the inner label layer. The color layer preferably does not break up in the information area. This will reveal a hidden piece of information that will remain visible even when the two layers of labels are placed on top of each other again. The term color layer is to be interpreted broadly here. Breaking it up changes the visual impression visible from the outside. It could also be transparent and rest on a continuous colored layer.

According to the invention, an information area is provided in the overlapping area, which covers information so that it is not visible from the outside if the first opening check has not yet been triggered. The information of the information area is preferably spatially separated from the information of the first opening proof. Preferably, the information area is free from the first tamper evidence and, favorably, the color layer does not break in the information area.

Preferably, the information area is provided on the inner label ply and covered by the outer label ply, and preferably has an adhesive connection to the outer label ply prior to initial opening of the first tamper evidence.

The information can be individually and inexpensively assigned to each seal label, e.g. B. by being printed on the information area. This is particularly suitable for winning codes of a raffle. In addition, the information also remains legible if the sealing label is glued on relief-like surfaces and the first opening proof does not trigger the entire surface.

The first first opening detection can be triggered by withdrawing the outer label layer from the inner label layer and preferably additionally pulling it off from the surface of the closure. The first opening proof can be designed as a so-called void effect. This is an effect that entrains layers and parts thereof by peeling off a carrier layer from a layer structure of the sealing label and by breaking up, z. As a color layer, a hidden in the layer structure information makes visible, which is not covered again and the first Erstöffnung proves. The information hidden in the first opening proof must be distinguished from the only hidden information in the information area.

The invention is particularly suitable for concealing information individualized for each sealing label, for example encrypted or immediately readable winning codes of a sweepstakes game.

Conveniently, the inner label layer on its inner side facing the closure parts has a preferably coherent and full-surface adhesive layer, with which the inner side is glued to the first closure part and to the second closure part and forms a second Erstöffnungsnachweis. The inner label layer is bonded both on the first closure part and on the second closure part. The bonds are each formed as fully as possible on the closure parts. However, it is also conceivable that the surface of at least one of the closure parts has a relief-like structure, so the bonds are made only partially and constantly interrupted. The bonds are nevertheless sufficiently strong, in order for a relative movement of the first and second closure part against each other, the second Initiate proof of first opening. The triggering happens in that the inner label layer tears irreversibly due to the relative movement.

Preferably, the inner label layer has an inner label strip which is preferably so long and conveniently provided on its inside with an adhesive layer that it is glued to the second closure part, while preferably the overlap region between the inner and outer label layer adhered to the first closure part is. For this purpose, an inner side of the inner label layer is preferably provided over the whole area with the adhesive layer and adhered with a portion on one surface of the first closure member and with another portion on a surface of the second closure member, so strong that during a relative movement of the two closure parts of the inner Label strip rips open.

In a further preferred embodiment of the invention, the outer label layer is preceded by an outer label strip, which is preferably provided on its inner side with an adhesive layer and is also adhesively bonded to the second closure part. Since the outer label layer in the overlapping area in the sealed state is firmly connected to the inner label layer forms in this embodiment, the outer label strip also forms part of the second Erstöffnungsnachweises by the opening of the closure in addition to the inner label strip and the outer label strip breaks and thus irreversible Detection of the opening of the closure embodied or the outer label strip does not tear. Then, when opening the shutter, only the first opening check is triggered.

Conveniently, the first Erstöffnungsnachweis is independently triggered by the second Erstöffnungsnachweis.

The first opening proof is preferably embodied by a void effect. One way of forming a void effect is in DE 10 2012 218 033 A1 disclosed. The disclosure of said document is fully incorporated herein. The first first opening detection is designed so that it is formed by separating the outer label layer of the inner label layer and possibly additionally the surface of the closure. Preferably, the separation takes place over the entire overlap area. The information is preferably printed only on the information area, but can also be integrated into the layer structure of the first opening inspection certificate.

Preferably, the outer label layer has a solid, non-tearable support layer so that the void effect is triggered by tearing off the outer label layer with the outer support layer. As long as the inner label ply is adhered to the fastener, the void effect is not restricted when the outer label ply tears off, even if the inner label ply and its backing layer are easily rupturable. The void effect may also refer to one or more areas where the outer label ply is applied directly to the surface of the closure and there is no inner label ply between the outer label ply and the surface of the closure.

Preferably, an adhesive layer, preferably a pressure-sensitive adhesive layer, is applied on the surface of the inner carrier layer facing the closure part, with which the inner carrier layer of the inner label layer can be glued onto the surface of the closure part.

A possible layer structure of the void effect is in DE 10 2012 218 033 A1 described. The outer label layer may have on the inside a PSA layer with which it is glued in the overlap region to the inner label layer and otherwise to the surface of the closure, preferably the first closure part. A second color layer may be applied to the adhesive layer, on which area a second adhesion-controlling layer is provided, and complementary thereto, spaced apart by a first color layer, a first adhesion-controlling layer, over which the carrier layer of the outer label layer is applied. By peeling off the outer label ply from the inner label ply, the first color coat breaks and reveals the covert information, preferably in the form of a readable or encrypted code. Preferably, the color layer breaks over the entire overlap area. The inner label layer may consist solely of an inner carrier layer. The carrier layer then has the information area in which the information is printed.

The inner label layer may be formed in several parts. It is preferably designed in several parts along its surface area. After removal of the outer label layer remaining on the closure inner label layer is then not formed contiguous.

The invention also relates to a series of sealing labels, wherein in each case at least one of the information areas of different sealing labels serialized code is printed. The code is serialized, ie each seal label is assigned a different individual code and introduced into the information area, preferably imprinted. Thus, a large number of different, preferably in pairs different, sealing labels can be produced. Such series are particularly suitable for the cost-effective production of sealing labels that contain as information the codes of a raffle.

The carrier layers can be made of paper or a plastic such as PE, PET or the like. consist.

In Fig. 1 an example of a closure 1 in the form of an inserted into an opening of a bottle neck 2 bottle cork 3 with a handle part 6 and a cork piece 7 is shown. However, other embodiments of the closure 1 are conceivable. For example, a perforated, rupturable tab, a can closure, etc. A sealing label 4 according to the invention is guided in the form of a sealing strip over the plastic grip part 6 of the bottle cork 3 from an outer wall of the bottle neck 2 over an upper side of the grip part 6 and optionally on the opposite side of the Bottleneck 2 out. The sealing label 4 may be glued to the outside on both sides of the bottle neck 2 or at least on one side of the bottle neck 2. The sealing label 4 is also glued to the outside, in particular top side of the grip part 6 of the bottle cork 3. The top of the handle portion 6 of the bottle cork 3 can be configured in relief.

The sealing label 4 forms a first opening inspection, which will be described below and in FIG. 3 is shown and after the first opening exposes various codes that are, for example, part of a sweepstakes. The codes are printed in an information area 8.

However, the sealing label 4 also includes a second tamper evidence which in a conventional manner provides proof of opening the bottle by tearing one or two label strips 18,19; by opening the bottle, the closure 1 is opened, so the bottle cork 3 relative to the bottle neck 2 is relatively moved and thereby the over a dividing line between bottle neck 2 and bottle cork 3 glued inner sealing strip, which is perforated or punched, torn. The tearing of the inner label strip 18 is irreversible.

The sealing label 4 has an outer label layer 11 and an inner label layer 12, the outer and inner label layers 11, 12 are shown schematically in FIG Fig. 2 shown. Both label layers 11, 12 are joined together in an overlapping area already during the production of the sealing label 4.

Fig. 2 shows the two-layer structure of the sealing label 4. Left, the outer label layer 11 and in the middle of the inner label layer 12 is shown, which together seal the 4 in Fig. 1 form. The outer label layer 11 has a widened portion 13 which is formed substantially square with rounded corners and in its extent completely covers a widened portion 14 of the inner label layer 12 in the sealed state, as the right of the three figures Fig. 2 shows.

The outer label layer 11 also has a grip 16, with which the outer label layer 11 can be removed from the inner label layer 12. The inner label layer 12 has in its widened region 14 the information area 8 with a code 17a and additionally an encrypted code 17b. From the widened region 14 is an inner label strip 18 from. From the outer label layer 11 is an outer label strip 19, wherein the outer label strip 19 is significantly shorter, about one fifth of the length of the inner label strip 18, is formed; The outer label strip 19 is in this embodiment exclusively with the closure part 6 of Bottle cork 3 glued and not so long formed that it comes into contact with the outside of the bottle neck 2. However, other embodiments are conceivable, which are so long form the outer label strip 19 that it is preferably adhered to the outer wall of the bottle neck 2 just like the inner label strip 18.

The inner label layer 12 has, on its inner side facing the closure, an entire adhesive layer with which it can be glued over the entire surface of the closure. The outer label layer 11 overlaps on the one hand the widened region 14 of the inner label layer 12 and is adhered to it by means of an adhesive layer and is otherwise also preferably provided on its inner side with an adhesive layer, with which they in a contact region of the outer label layer 11 with the Surface of the closure 1 may be glued to the closure 1.

The overlapping widened areas 13, 14 of the two label layers 11, 12 and the contact area of the outer label layer 11 on the surface of the closure 1 together form a first opening inspection; this can be designed in the form of a void effect in various ways. One possible education is in DE 10 2012 218 033 A1 released; the disclosure of this document is fully incorporated here.

The first first opening detection is accommodated in the outer label layer 11. The outer label layer 11 is adhered to the inner label layer 12 by means of a pressure-sensitive adhesive layer. The pressure-sensitive adhesive layer is immediately followed by a second color layer. A second adhesion-controlling layer is arranged in regions between the second color layer and a first color layer. Between a first adhesion-controlling layer and the second adhesion-controlling layer, the first color layer is arranged, which breaks apart on detachment of the outer label layer 11 from the inner label layer 12 and forms a void effect. The carrier layer of the outer label layer 11 as well as the adhesion-controlling layers, in particular the first adhesion-controlling layer, may preferably be transparent. Before the first initial opening, only the first color layer can be seen from the outside. After breaking open the sealing label 4, the inner label layer 12 sticks to the handle part 6. The outer label layer 11 is peeled off and removed. On the part of the first opening proof, which according to the middle representation of the Fig. 3 on the inside Label layer 12 remains, the second color layer can be seen. The right representation of the Fig. 3 shows the withdrawn part of the sealing label 4.

Although the detached part can be pressed again on the remaining part to hide the codes 17a, 17b; the triggered first opening proof in the form of the opened locks remains recognizable.
