Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to a container wet glue label with a relief-like embossing, which is intended in particular as a bottle wet glue label for beverage bottles such as beer bottles, wine bottles, bottles for spirits or for non-alcoholic beverages or for containers such as beverage cans or also for spray cans or mugs. The invention also relates to a container or a bottle with such a wet-glue container label. Finally, the invention also relates to a wet glue label embossing tool, in particular a die and / or male mold, by means of which container wet glue labels with a type of relief can be produced.

STATE OF THE ART

From the patent applications not previously published GB 1 411 146.2 and GB 1 419 890.7 A container wet glue label is known to the applicant in which a substrate is provided with wet glue on the back and which is then glued to a bottle with the wet glue. In order to improve the visual appearance and / or the tactile effect of the container wet glue label, the substrate is provided with embossing prior to the application of the wet glue, so that the visual appearance and the tactile effect of the container wet glue label in addition to the choice of material for the substrate and the Printing can be influenced by a kind of relief. In these patent applications it is described as problematic that, in particular for a substrate with cellulose fibers such as paper, the application of the wet glue can lead to an impairment of the embossing or relief-like structure of the container wet glue label, which also affects the desired visual effect and the tactile effect . To remedy this, it is suggested that the wet glue be applied to a Contact with the embossed areas of the substrate is prevented. According to a first proposal, this can be ensured by applying the wet glue to the substrate only apart from the embossing. For example, the application of the wet glue can take place via the contact of the substrate with a contact partner coated with the wet glue, for example a roller or a so-called glue or adhesive pallet, the contact partner having a recess in the contact area with the embossings so that no Contact and therefore no application of the wet glue takes place. For another suggestion, the back of the substrate is provided with a water-impermeable layer in the area of the embossing before the application of the wet glue. Even when the wet glue is applied over the entire surface of the substrate, the water-impermeable layer then prevents the wet glue from coming into contact with the embossing of the substrate. Such a water-impermeable layer can for example consist of a lacquer with or without a wax component. In particular, the use of a substrate made of paper, cellulose fibers and / or a substrate with a water-permeable film material is proposed. For a water-impermeable layer, in particular a layer with a low water-vapor transmission rate (WVTR), in particular with a WVTR <10 g / m ² / day or WVTR <5 g / m ² / day. The wet glue can, for example, be applied to the substrate at 15-20 g / m ² , whereby this can contain approximately 50% water (± 10%). Possible components of the wet glue are vegetable glue, resin cement, animal glue, protein glue, latex cement, starch glue, dextrin glue, casein glue, EVA, PVA, non-casein-based polymeric glues such as synthetic glues or adhesives including those with acrylates as binders. It is also possible that the front side of the substrate (completely or only in partial areas) is equipped with a water-impermeable layer, which is considered to be advantageous in terms of maintaining the embossing, especially when stacking, storing and further processing the container wet-glue labels. Here, the water-impermeable layer on the front side can also be formed with water-impermeable ink. If a paper substrate is used, thicknesses between 50 g / m ² and 300 g / m ² , preferably between 60 g / m ² and 120 g / m ² or between 60 g / m ² and 90 g / m ² , be used.

DE 10 2008 023 653 A1 relates to a label stuck to a container such as a bottle by means of adhesive. The label has a two-layer design with an external, to printing layer, which consists in particular of paper or cardboard, and an inner layer, which is preferably an embossing film. The label is embossed in three dimensions between a die and a male die. DE 10 2008 023 653 A1 describes the problem that the quality of the embossed three-dimensional relief suffers as a result of the moisture penetration of a pure paper label. According to DE 10 2008 023 653 A1 the inner layer, which is insoluble with respect to the adhesive, is intended to avoid moisture penetration of the outer layer made of paper. Letters, words, graphic patterns or images can be embossed. It is further proposed that only the recessed sections of the relief embossing facing the bottle are provided with the layer that is inseparable from the adhesive. The additional inner layer can also be an embossing foil which is initially arranged on a carrier foil. A separating layer (wax), a decorative lacquer (resin), a metallization (aluminum) and an adhesive layer (hot-melt adhesive) can be arranged on the carrier film. The embossing foil (in contrast to conventional embossing labels) is used as counter-embossing on the inside of the label.

DE 20 2004 002 207 U1 relates to a wet glue label for a container such as a returnable bottle, which has a stretched plastic film that shrinks back under the action of heat to detach the label from the bottle. DE 20 2004 002 207 U1 suggests that the glue side of the label be structured to increase the area. Mechanical or chemical roughening, surface-enlarging embossing or fine embossing can be used here, an embossing depth of <20 μm being preferred, which can approximate the thickness of the plastic film. This surface-enlarging structuring is intended to achieve better adhesion of the label to the bottle, while embossed recesses should be filled with glue so that the surface-enlarging structuring should not be visually visible. It is also possible to emboss a rib or groove pattern with widths of the ribs of <1 mm or <2 mm in order to improve the penetration of the washing liquid. Preferably, despite the production of the embossments on the underside of the label, the upper side of the label should be essentially smooth or wavy. The top of the label can have a decorative print, a lamination layer or other layers of shrink film. It is also possible that the glue side of the label is provided with a rough and matt lacquer layer. The label can be perforated so that it is permeable to air and vapor. It is also possible that the label is provided on the glue side with a layer that absorbs the moisture from the glue. This can be an open-pored foamed plastic layer or an absorbent, swelling layer. A stretched plastic film with a thickness in the range of 50 is used up to 80 µm, while the wet glue is applied with a thickness of 20 to 50 µm. The material used for the thermally shrinking plastic film is PET, PS, PVC or PP.

U.S. 1,850,856 relates to a machine for producing an ornament-like embossed metallic elongated strip material which is to be used in particular as an ornament for sheets of paper, boxes, packages or wallpaper or as a tag, for example for packages. A multiplicity of identical embossed ornaments hang together in the strip material. To produce the ornament-like embossed strip material, a metal sheet is plastically deformed between dies by embossing a pattern into it. At the same time, the machine cuts the edges with the dies so that the metal sheet is divided into a central strip with the pattern and edges separated on both sides. The edges and the side edges of the central strip have a complex, likewise ornament-like and repetitive contour.

U.S. 3,584,572 relates to a machine with a die with which a multi-layer label is simultaneously embossed and cut from a material web, as well as for applying a film or a plastic under heat and pressure. The machine has a press with a reciprocating piston. In the area of the press, a continuous first web of an elastic substance such as rubber or another flexible or elastomeric substance is bonded to a second web of paper foil or a thin metal. In addition, a third web is applied, which has a film or a plastic that is to be transferred to the second web. The die interacts with the third web, whereby the plastic or the film is applied to the second web. The first, supporting track ensures sufficient flexibility of the connected tracks. The second web can be embossed by means of the die and in the same method step the label embossed in this way can be cut out of the connected webs by means of the die. It is also possible that an inner embossing edge is arranged on the die, with which the label can be embossed at the same time at a distance from an edge of the label cut in this way.

U.S. 5,857,275 relates to a label for a bottle that is intended to enable the bottle to be gripped securely. For this purpose, the label should have rib-like projections that should improve gripping. The protrusions are created by first applying strips of a material made of plastic, paper or cardboard to the bottle. This is followed by a Label strips made of paper or plastic are applied to the bottle in the area of the strips attached. The label strip is glued to the bottle between the strips for the protrusions. As a result, in the area of the strips for the projections, the label strip bulges in accordance with a desired contour predetermined by the strips and forms the projections. The projections can have a U-shaped cross section with side legs that are parallel or pointing apart, a V-shaped cross section or a semicircular cross section.

Furthermore, the invention is based on the object of proposing a wet glue label embossing tool, in particular a die and / or a male mold, by means of which a correspondingly improved container wet glue label can be produced.

SOLUTION

DESCRIPTION OF THE INVENTION

• Applikation des Nassleims auf das Substrat,
• Aufbringung des Behälter-Nassleimetiketts auf eine (bspw. nasse oder trockene, kalte oder warme) Flasche und
• Trocknung des Behälter-Nassleimetiketts und des Nassleims auf der Flasche (diese Schritte werden im Folgenden auch gemeinsam als "Applikationsvorgang" bezeichnet)

die optische und taktile Wirkung des reliefartig geprägten Bereichs nicht mehr wunschgemäß ist. Beispielsweise ist ein Teil oder sogar Großteil einer während des Prägevorgangs herbeigeführten Prägetiefe am Ende des Applikationsvorgangs wieder beseitigt. Eine vermutete Ursache hierfür ist, dass bei Ausbildung des Substrats mit Zellulose-Fasern die Fasern bei Beaufschlagung des Substrats mit dem Nassleim die Feuchtigkeit des Nassleims aufnehmen, womit es zu einer Expansion der Fasern und damit des Substrats kommen kann. Wird das Behälter-Nassleimetikett in diesem feuchten expandierten Zustand auf die Flasche appliziert, führt das anschließende Trocknen zu einer Kontraktion der Fasern und damit des Substrats. Während einerseits eine derartige Kontraktion der Fasern gewünscht ist, um nach der Applikation des Behälter-Nassleimetiketts auf die Flasche verbleibende Falten des Behälter-Nassleimetiketts zu beseitigen, führt die Kontraktion auch zu dem unerwünschten Effekt, dass zuvor erzeugte reliefartig geprägte Bereiche des Substrats zumindest teilweise "glattgezogen" oder "eingeebnet" werden. Möglich ist auch, dass das feuchte Behälter-Nassleimetikett unter Druck, beispielsweise einer Bürste, auf die Flasche appliziert wird, womit u. U. reliefartig geprägte Bereiche herausgedrückt werden.The invention is based on the knowledge that after a substrate has been produced, a label with a region embossed in relief as desired and afterwards

• Application of the wet glue to the substrate,
• Application of the container wet glue label to a (e.g. wet or dry, cold or warm) bottle and
• Drying of the container wet glue label and the wet glue on the bottle (these steps are also referred to collectively as the "application process" in the following)

the visual and tactile effect of the relief-like embossed area is no longer as desired. For example, a part or even a large part of an embossing depth brought about during the embossing process is eliminated again at the end of the application process. One suspected reason for this is that when the substrate is formed with cellulose fibers, the fibers absorb the moisture of the wet glue when the substrate is exposed to the wet glue, which can lead to an expansion of the fibers and thus of the substrate. If the container wet glue label is applied to the bottle in this moist, expanded state, the subsequent drying leads to a contraction of the fibers and thus of the substrate. While on the one hand such a contraction of the fibers is desired in order to eliminate wrinkles of the container wet glue label remaining after the application of the container wet glue label on the bottle, the contraction also leads to the undesirable effect that previously created relief-like embossed areas of the substrate are at least partially " be smoothed out "or" leveled out ". It is also possible that the moist container wet glue label is applied to the bottle under pressure, for example a brush, with which u. U. relief-like embossed areas are pressed out.

• einem Ausgangskonturbereich,
• einem Prägekonturbereich sowie
• einem verlagerten Konturbereich

der Prägekontur. Hierbei beschreibt der Ausgangskonturbereich den Konturbereich des Substrats, welcher während des Prägevorgangs weder seine Form ändert noch verlagert wird und welcher keine Prägetiefe besitzt. Der Prägekonturbereich beschreibt den Bereich, in welchem während des Prägens eine plastische Verformung des Substrats erfolgt, in welchem sich die Prägetiefe ändert und in welchem das Substrat infolge des Prägens geneigt ist, wobei sich in dem Prägekonturbereich die Neigung des Substrats auch ändern kann. Schließlich bezeichnet der verlagerte Konturbereich einen Konturbereich, welcher selber während des Prägens seine Form nicht ändert, welcher aber mit der Prägetiefe, die durch den angrenzenden Prägekonturbereich erzeugt wird, gegenüber dem Ausgangskonturbereich verlagert ist.In the context of the following description of the invention, a distinction is made between

• an initial contour area,
• an embossing contour area and
• a relocated contour area

the embossing contour. Here, the initial contour area describes the contour area of the substrate which neither changes its shape nor is displaced during the embossing process and which has no embossing depth. The embossing contour area describes the area in which a plastic deformation of the substrate occurs during embossing, in which the embossing depth changes and in which the substrate is inclined as a result of the embossing, the inclination of the substrate also being able to change in the embossing contour area. Finally, the displaced contour area denotes a contour area which itself does not change its shape during the embossing, but which is displaced with the embossing depth that is generated by the adjacent embossing contour area in relation to the initial contour area.

The invention proposes that a wet glue label embossing tool for a container wet glue label having a substrate has an embossing contour area. The embossed contour area is inclined here in relation to the main plane of extent. According to the invention, the embossed contour area has an embossed contour partial area. This embossing contour sub-area has a contour angle of at least 45 ° with respect to the main plane of extent of the wet glue label embossing tool. Tests on which the invention is based have shown that with the selection of such a contour angle the resistance of the embossed area of the container wet glue label can be increased and even after the application process an embossed area remains which meets the optical and tactile requirements better than container wet glue labels which have been produced with wet glue label embossing tools according to the prior art, especially since a greater embossing depth remains. Possibly the reason for this is that the selection of an embossing contour sub-area with a contour angle of at least 45 ° results in a relatively large deformation of the substrate, which also results in a relatively large plastic lengthening of the contour of the substrate in the embossing contour area during the embossing process. The embossing and embossing depth remaining after the container wet glue label has dried depends on the difference between the lengthening of the contour of the substrate brought about during the embossing and the contraction of the substrate during the subsequent application and drying process. Thus, by increasing the elongation of the substrate during the embossing process by choosing an advantageous contour angle of the wet glue label embossing tool, the optical and tactile effect of the container wet glue label at the end of the application process can be improved.

• Einerseits ist aus den zuvor erläuterten Gründen zur möglichst großen Verlängerung des Prägekonturbereichs während des Prägens ein möglichst großer Konturwinkel gewünscht.
• Andererseits steigt mit der Vergrößerung des Konturwinkels u. U. auch die Neigung des Substrats, während des Prägevorgangs oder während der nachfolgenden Bearbeitung zu reißen oder brechen, so dass zur Vermeidung eines Reißens oder Brechens eher ein kleiner Konturwinkel angestrebt werden müsste.

In principle, any desired contour angle can be used, provided that it is at least 45 ° with respect to the main extension plane. However, further studies on which the invention is based have led to the result that u. There may be a conflict of objectives when choosing the contour angle:

• On the one hand, for the reasons explained above, the greatest possible length of the embossing contour area during the embossing process is desired.
• On the other hand, the increase in the contour angle u. U. also the tendency of the substrate to increase during the embossing process or during the subsequent processing tear or break, so that in order to avoid tearing or breaking a small contour angle would have to be aimed for.

The choice of the contour angle also has an impact on the stacking density of several container wet glue labels in a stack: For a theoretical contour angle of 90 °, the container wet glue labels can no longer be stacked directly on top of one another in such a way that an embossing projection formed from the front of the container wet glue label occurs into a corresponding embossing recess of the container wet glue label arranged adjacent in the stack, which would reduce the stack density. By reducing the angle compared to the extreme theoretical contour angle of 90 °, the stacking density can be increased. Under certain circumstances, a reduction in the contour angle also simplifies "digging out" of an embossing projection of a container wet-glue label from an embossing recess of an adjacent container wet-glue label.

According to the invention, it has been found that the explained conflict of objectives can be taken into account particularly well if the contour angle is in the range from 45 ° to 55 °, in particular in the range from 48 ° to 52 °.

The measures explained above were primarily aimed at the extent of the change in shape and lengthening of the embossing contour area during the embossing of the container wet glue label with the wet glue label embossing tool in order to keep the remaining embossing depth as large as possible. Further investigations have led to the result that it can be particularly advantageous if a transition from a non-embossed initial contour area to the embossed contour area takes place via a kink. It was found that such a kink remains at the transition mentioned at the end of the machining process and can be detected optically and tactilely, even if u. U. an embossing depth is reduced during drying as a result of the contraction. In some cases, such a kink at the transition is also advantageous for obtaining the greatest possible embossing depth after the container wet glue label has dried on the bottle. However, it is also entirely possible that even when the container wet glue label is embossed with a wet glue label embossing tool with a kink in the embossing contour area at the transition, the container wet glue label no longer has a bend at the transition after it has been removed from the wet glue label embossing tool. In principle, the embossed contour partial area, the contour angle of which is at least 45 ° and which is in particular in the range from 45 ° to 55 ° or in the range from 48 ° to 52 °, can be located at any point in the embossed contour area. For a special suggestion, this embossing contour sub-area directly adjoins the kink with the previously specified contour angle.

It is possible that the embossing contour area also merges with a kink into a displaced contour area. For a special proposal according to the invention, however, the embossed contour area merges into a displaced contour area without a kink, which has proven to be particularly advantageous with regard to the optical and tactile effect of the container wet glue label.

• Gemäß einem ersten Vorschlag besitzt der verlagerte Konturbereich eine Prägetiefe im Bereich von 0,200 mm bis 0,260 mm von dem nicht geprägten Ausgangskonturbereich. Alternativ oder zusätzlich möglich ist, dass der Prägekonturbereich in der Haupterstreckungsebene eine Erstreckung besitzt, welche im Bereich von 0,300 mm und 0,400 mm liegt.
  Möglich ist hierbei, dass der Prägekonturbereich mit einem Knick und einem daran anschließenden Konturwinkel im Bereich von 48° bis 52° beginnt. Der Prägekonturbereich besitzt in diesem Fall einen Abstand von dem Knick in der Haupterstreckungsebene von 0,1998 mm ± 10 % eine Prägetiefe von 0,204 mm ± 10 %, in einem entsprechenden Abstand von 0,277 mm ± 10% eine Prägetiefe von 0,228 mm ± 10 % sowie in einem entsprechenden Abstand von 0,338 mm ± 10 % eine Prägetiefe von 0,230 mm ± 10 %.
• Für eine zweite Ausführungsform besitzt der verlagerte Konturbereich eine Prägetiefe im Bereich von 0,120 mm bis 0,160 mm von dem nicht geprägten Ausgangskonturbereich. Alternativ oder kumulativ möglich ist, dass der Prägekonturbereich in der Haupterstreckungsebene eine Erstreckung besitzt, welche im Bereich von 0,185 mm und 0,210 mm liegt.
  Möglich ist hierbei, dass der Prägekonturbereich mit einem Knick und einem daran anschließenden Konturwinkel im Bereich von 48° bis 52° beginnt, während der Prägekonturbereich in einem Abstand von dem Knick in der Haupterstreckungsebene von 0,096 mm ± 10 % eine Prägetiefe von 0,096 mm ± 10 % besitzt und in einem entsprechenden Abstand von 0,197 mm ± 10% eine Prägetiefe von 0,140 mm ± 10% besitzt.
• Für eine dritte Ausführungsform besitzt der verlagerte Konturbereich eine Prägetiefe im Bereich von 0,190 mm bis 0,230 mm von dem nicht geprägten Ausgangskonturbereich. Alternativ oder kumulativ möglich ist, dass der Prägekonturbereich in der Haupterstreckungsebene eine Erstreckung besitzt, welche im Bereich von 0,250 mm und 0,280 mm liegt.

Further refinements of the invention have specific refinements of the embossing contour as their subject:

• According to a first suggestion, the displaced contour area has an embossing depth in the range from 0.200 mm to 0.260 mm from the unembossed initial contour area. As an alternative or in addition, it is possible for the embossed contour area in the main plane of extent to have an extent which is in the range of 0.300 mm and 0.400 mm.
  It is possible here for the embossed contour area to begin with a kink and an adjoining contour angle in the range from 48 ° to 52 °. In this case, the embossed contour area has a distance from the bend in the main extension plane of 0.1998 mm ± 10%, an embossing depth of 0.204 mm ± 10%, and at a corresponding distance of 0.277 mm ± 10%, an embossing depth of 0.228 mm ± 10% at a corresponding distance of 0.338 mm ± 10%, an embossing depth of 0.230 mm ± 10%.
• For a second embodiment, the displaced contour area has an embossing depth in the range from 0.120 mm to 0.160 mm from the non-embossed initial contour area. Alternatively or cumulatively, it is possible for the embossed contour area in the main plane of extent to have an extent which is in the range of 0.185 mm and 0.210 mm.
  It is possible here for the embossed contour area to begin with a kink and an adjoining contour angle in the range from 48 ° to 52 °, while the embossed contour area at a distance from the bend in the main extension plane of 0.096 mm ± 10% has an embossing depth of 0.096 mm ± 10 % and has an embossing depth of 0.140 mm ± 10% at a corresponding distance of 0.197 mm ± 10%.
• For a third embodiment, the displaced contour area has an embossing depth in the range from 0.190 mm to 0.230 mm from the non-embossed initial contour area. Alternatively or cumulatively, it is possible for the embossed contour area in the main plane of extent to have an extent which is in the range of 0.250 mm and 0.280 mm.

It is possible here for the embossed contour area to begin with a kink and an adjoining contour angle in the range from 48 ° to 52 °, while the embossed contour area at a distance from the bend in the main extension plane of 0.134 mm ± 10% has an embossing depth of 0.141 mm ± 10 % and has an embossing depth of 0.210 mm ± 10% at a corresponding distance of 0.262 mm ± 10%.

For a further proposal of the invention, a displaced contour area is arranged between two embossed contour areas which are oriented in different directions and with which in particular boundaries of an embossed area are formed. This should be explained, for example, using the embossing of lines or digits such as letters or numbers: The embossing contour areas oriented in different directions, here in particular the kinks at the transition from the initial contour area to the embossing contour area, form the lateral boundaries for specifying the "line thickness" of the lines or Digits. In contrast, the line width is formed with the shifted contour area. It is possible for the line thickness to be constant, so that the two embossed contour areas oriented in different directions have a constant spacing with a displaced contour area between them, the length of which does not change in the direction in which the line extends. In the event that a changing line thickness is desired, the lateral delimitation of the line is still formed with the two embossed contour areas oriented in different directions, without that their contours change. However, the length of the displaced contour area changes along the line to change the line thickness.

However, it is also possible that different embossed contour areas are provided for the formation of lines or digits on the container wet glue label with different line thicknesses and / or sizes, the embossed contour areas for lines and / or digits with different line thicknesses and / or sizes then being established differentiate between different extensions of the embossed contour areas in the main plane of extension. This can be the case for the same or different contour angles, the contour angle preferably being in the range from 48 ° to 52 °. It is then possible for the different embossed contour areas to differ, depending on the line thickness and / or size, also by the different embossing depths in the embossed contour areas. Preferably, larger extensions of the embossed contour areas in the main plane of extension are used for larger line widths and / or larger digits than for smaller line widths or smaller digits.

For a further solution according to the invention, in which the wet glue label embossing tool for the container wet glue label is possibly designed as explained above, several embossed areas are arranged side by side in the manner of a waffle pattern. In this way, the "density" of the embossing contours and the deformations can be increased and thus the lengthening of the container wet glue label as a result of the embossing, based on the area, can be increased. The formulation here includes that several embossed areas are arranged next to one another in the manner of a waffle pattern, both the arrangement of several embossing areas next to one another along a straight line or curve and also next to one another in a surface, i.e. with the arrangement of the embossing areas next to one another in two different directions. Here, “lying next to one another” includes in particular a distance between adjacent embossing areas of less than 0.50 mm, less than 0.30 mm or even less than 0.20 mm.

Basically, the embossing can take place in the manner of a waffle pattern with any embossing geometries which can have the same or different embossing depths and the same or different embossing contours. In a particular embodiment of the invention, the multiple areas are adjacent to one another in the manner of a waffle pattern are arranged, cuboid, pyramid-like, truncated pyramid-like, cone-like, truncated cone-like, cylindrical, corresponding to an obliquely cut cylinder, spherical segment-like, spherical layer-like and / or shaped like a prismatoid.

It is entirely possible that a desired optical and / or tactile effect in the area of the embossed contour is brought about exclusively as a result of the embossed contour. In a particular embodiment of the invention, the embossing contour is arranged in an edge region of an optical field of view of the container wet glue label. A surface area of the container wet glue label which stands out optically from the surrounding area is referred to as the optical field of view. Here, the contrast can be brought about, for example, by choosing different colors, brightnesses, surface structures, materials and / or different gloss levels. Due to the coincidence according to the invention of the deformations of the container wet glue label by the embossing contour areas with an edge area of the optical field of view, a particularly strong and u. U. also plastic optical and / or tactile effect can be brought about and / or the optical field of view can be further emphasized optically and / or tactilely.

It is entirely possible for an embossed contour area to be arranged in an edge area of an optical field of view, in particular a colored area of the container wet glue label, with the result that the optical field of view is largely arranged in the area of the displaced contour area. This has u. The result may be that in the optical field of view, namely in the area of the displaced contour area, the container wet glue label cannot be glued to the bottle or this is only possible in part. In order to avoid this and / or to maintain the optical and / or tactile effect even after the application process, the invention also proposes that (in particular in an edge area of an optical field of view) two embossing contour areas oriented in different directions (as one the Embossing contour area increasing the embossing depth and an embossing contour area reducing the embossing depth again or even leading back to the profile depth from zero). In other words, a reciprocating deformation of the substrate occurs during the embossing (in particular in the edge region of the optical field of view). In this way, the substrate protrudes outward only in the edge area between the two embossed contour areas oriented in different directions, while the actual optical field of view can rest almost completely directly on the container and can be glued to it. On the other hand, the embossing in the edge area has been oriented in different directions Embossing contour areas mean that, compared to the use of only one embossing contour area, a greater deformation with a larger lengthening of the container wet glue label can be brought about during the embossing, which in terms of the desired optical and / or tactile effect and / or the durability of the embossing result even during the application process can be beneficial.

The invention also relates to a container wet-glue label which has a substrate. The container wet-glue label is equipped with an embossed area which has been brought about with a wet-glue label embossing tool of the type explained above. As a result of the embossing with the wet-glue label embossing tool, an embossing contour can result on the substrate which is identical to the embossing contour of the wet-glue label embossing tool. Preferably, however, after the embossing of the substrate with the wet glue label embossing tool, the substrate has an embossing contour which deviates from the embossing contour of the wet glue label embossing tool. For example, a reduced contour angle can result. An embossing depth of the container wet glue label can also be reduced compared to the embossing depth of the wet glue label embossing tool. It is also possible that a kink in the embossing contour of the wet glue label embossing tool is larger than a bend brought about on the substrate and / or radii of the embossing contour of the wet glue label embossing tool are smaller than the radius resulting on the substrate. Finally, it is also possible for the displaced contour area to partially collapse or for the embossed contour to be "pulled apart".

For a further proposal of the invention, in the case of a container wet glue label, which can be designed as explained above, the substrate is structurally strengthened in order to bring about an embossing result that is as stable as possible. For this proposal, the substrate is a laminate with a paper layer and an aluminum layer (which can be the only layers or there can be additional layers). This embodiment is based on the knowledge that the aluminum layer, which can be an aluminum foil, acts as a kind of “stabilizer” which does not react to the changing moisture during the application process. Under certain circumstances, an embossing contour that has been brought about once in the aluminum layer is also more permanent than an embossing contour that is merely produced in paper as a result of the "stabilizer" formed by the aluminum layer.

Within the scope of the invention, the aluminum layer can be produced in any way and can have any layer thickness. The aluminum layer is preferably an aluminum layer with a layer thickness of 5 to 9 μm.

While any alloy can be used for the aluminum of the aluminum layer, it has been found that an aluminum layer made of an 8011, 8079 or 8021 alloy can preferably be used.

For an alternative or cumulative solution to the problem on which the invention is based, a substrate is used in the container wet glue label, which is formed with paper and an aluminum layer vapor-deposited onto the paper. A very thin aluminum layer, preferably with a layer thickness of less than 1 μm, can possibly also be produced with the vapor deposition.

For a further proposal for solving the problem on which the invention is based, which can certainly also be used in conjunction with the measures explained above, the substrate has a layer made of a thermoplastic material. During the embossing, the material can heat up anyway, causing it to be thermoplastically deformed. Alternatively or cumulatively, it is possible for the material to be heated during the embossing process by an external heat source, ultrasound and the like. Ä. takes place. After cooling, the thermoplastic material helps stabilize and maintain the relief-like embossing.

A water-repellent coating is used for a further proposal of the invention. Alternatively or cumulatively, it is also possible to use a coating.

Under certain circumstances, the thermoplastic material, the water-repellent coating and / or the paint is arranged over the entire surface or part of the surface on the back of the substrate, with what u. U. an application of the container wet glue label that is as free from creases as possible can be supported.

FIGURE DESCRIPTION

In the Figures 1 to 8 a container wet glue label 1 with a substrate 2 is shown. The substrate 2 is embossed or deformed to form an embossed contour 3. The embossing contour 3 has an initial contour area 4, the shape and orientation of which remains essentially unchanged during the embossing and which has no embossing depth. The initial contour area 4 merges at a transition 9 into an embossed contour area 5. The plastic deformation of the substrate 2 takes place primarily in the embossed contour area 5, in which the material areas of the substrate 2 are displaced and deformed during the embossing process and change their orientation. In the embossing contour area 5, the embossing depth 6 increases continuously until it is at a maximum in the area of a transition 8 to a displaced contour area 7. In the displaced contour area 7, the substrate 2 is displaced relative to the initial contour area 4 by the maximum embossing depth 6 of the embossing contour area 5, which is reached in the area of the transition 8, without plastic deformation of the same and without any change in inclination and deflection. For a simplified view, a plastic deformation with an elongation of the material of the substrate 2 takes place exclusively in the embossed contour area 5. Under certain circumstances, however, the deformation in the embossed contour area 5 also leads to an elongation of the material of the substrate 2 in an area of the initial contour area 4 directly adjacent to the embossed contour area 5 and / or the displaced contour area 7.

A rear side 10 of the substrate 2 has a wet glue applied to it and faces the bottle when the container wet glue label is applied. In contrast, a front side 11 of the substrate 2 forms a visible surface of the container wet glue label 1 in the state applied to the bottle.

In the figures, the substrate 2 is shown in simplified form, it being possible for several layers or coatings (in partial areas or over the entire surface) to be present. In the exemplary embodiments, different embossed contours 3a, 3b of a substrate are identified with additional letters a, b.

For the in Fig. 1 In the exemplary embodiment shown, the embossed contour area 5 is formed exclusively with a rectilinear embossed contour sub-area 12. Compared to a main plane 13 of extent 13 of the substrate 2, the embossed contour sub-area 12 is inclined with a contour angle 14 of approximately 30 °. The transitions 8, 9 are formed here with kinks. May come For this configuration in the area of the transitions 8, 9 there is mechanical impairment of the substrate 2, in the worst case an edge break.

Fig. 2 shows the result after applying the wet glue, applying the container wet glue label 1 to the bottle and drying. It can be seen here that the relatively wide surfaces in the displaced contour area 7 and in the embossing contour area 5 "fall in", so that the embossing depth 6 in particular decreases with increasing distance from the transition 8, the contour angle 14 is reduced and the previously straight-line displaced contour areas 7 as well as Curve the embossing contour areas 5 (cf. Fig. 2 ).

For those in the Figs. 3 to 5 In the illustrated embodiment, the embossed contour area 5 is not formed in a straight line. Rather, in the area of the transition 9, it merges with a bend into a straight embossed contour sub-area 12, for which the contour angle 14 is greater than for the exemplary embodiment according to FIG Fig. 1 . Subsequently, the contour angle 14 decreases continuously so that there is no kink in the area of the transition 8 to a displaced contour area 7. Under certain circumstances, the extent of the displaced contour area 7 is even minimized for the two adjacent embossed contours 3a, 3b, so that the extent is only small or even the two embossed contours 3a, 3b merge into one another without a displaced contour area 7, which can then take place without any kink . Thus, here the contour formed with the embossing contours 3a, 3b between the transitions 9 of the adjacent embossing contours 3a, 3b has a curved course with a constant change in the angle of inclination 14, the angle of inclination continuously increasing or increasing from the contour angle in the area of the transition 9 of an embossing contour 3a drops down to the transition 9 of the other embossed contour 3b. Since non-curved surfaces are reduced and the relief-like embossing has a relatively soft design in the embossing depth, this results in a comparison with the exemplary embodiment according to FIG Figs. 1 and 2 u. U. improved visual and / or tactile effect after the application process. Under certain circumstances, however, there is also a certain dip in the embossing depth in the area of the displaced contour area 7 or in the transition area between the adjacent embossing contours 3a, 3b, which may be undesirable. Fig. 5 shows a container wet glue label 1 in a plan view in a region of a line of lettering, the line having the embossed contours 3a, 3b according to FIG Fig. 3 is shaped. It can be seen here that the distance between the transitions 9 of the embossed contours 3a, 3b varies for a changing line thickness. There may also be a tendency for this configuration to break or to mechanical impairment in the area of the transitions 9.

For the embodiment according to Fig. 6 to 8 Both transitions 8, 9 are embossed "soft" or rounded so that there are no kinks here. Rather, a rounding 15 with a small radius is provided in the area of the transition 9, which is then followed by the embossed contour sub-area 12 with the large contour angle 14, while the contour angle 14 is then gradually reduced again, this reduction with an at least five or ten times larger radius or a corresponding change in the curvature takes place than in the area of the rounding 15. The embossed contour area 5 is thus curved back and forth in an S-shape, the part of the S adjacent to the transition 9 being formed by the rounding 15 with a small radius, while the other part of the S has a much larger diameter. Under certain circumstances, the embossing contour 3 has after the application process Fig. 7 a good embossing result with the desired visual and / or tactile effect. In particular, there is no incidence of a "roof" of the embossing, as is the case according to Fig. 2 and 4th was the case. Under certain circumstances, as a result of the elimination of the kinks, there is also a reduced tendency to mechanical impairment or even a break in the area of the transitions 8, 9. However, the transition 9 is preferably formed from a bend (with an otherwise corresponding design).

Fig. 8 shows a plan view of a container wet glue label 1 or a substrate 2 with embossed contours 3a, 3b accordingly Fig. 6 .

In the Figs. 9-11 different embossing contours 3a of a wet glue label embossing tool 32 are shown. Even if the embossing depths, the contour angles, embossing contour areas and displaced contour areas of the container wet glue labels 1 produced with the wet glue label embossing tool 32 can differ from those of the wet glue label embossing tool 32, which was used for its embossing process, the same reference symbols and designations are used here been. In this case, the embossing contour 3a can be applied to a die 33 forming the wet-glue label embossing tool 32 (in Figs. 9-11 be formed above the embossing contour 3a) or (in the case of complementary contouring) on a male part 34 (in FIG. 3) forming the wet glue label embossing tool 32 Figs. 9-11 be formed below the embossing contour 3a).

In the Figures 9 to 11 the embossing depth 6 is shown as a function of a coordinate 16 in the direction of the main extension plane 13. For the embossing contour 3a according to Fig. 9 the transition 9 from the initial contour area 4 to the embossed contour area 5a takes place with a kink. The embossed contour sub-area 12 has, adjacent to the transition 9, a contour angle 14 which is preferably in the range from 48 ° to 52 °. At a distance 17 of 0.198 mm, the profile depth 6 is 0.204 mm, while at a distance 18 of 0.277 mm, the profile depth 6 is 0.228 mm and the transition 8 is arranged at a distance 19 of 0.338 mm with a profile depth 6 of 0.230 mm.

Also for the embossing contour 3a according to Fig. 10 there is a kink in the area of the transition 9, in the area of which the embossed contour sub-area 12 has a contour angle 14 of 48 ° to 52 °. At a distance 20 of 0.096 mm from the transition 9, the profile depth 6 is 0.096 mm, while at a distance 21 from the transition 9 of 0.197 mm, the profile depth 6 is 0.140 mm.

For the embossing contour 3a according to Fig. 11 there is also a kink in the area of transition 9. The embossing contour partial area 12 adjoins the bend with a contour angle 14 in the range from 48 ° to 52 °. At a distance 22 from the transition 9 of 0.134 mm, the profile depth 6 is 0.141 mm, while the transition 8 is arranged at a distance 23 of 0.262 mm with a profile depth 6 of 0.210 mm. It goes without saying that, in contrast to the illustrated embodiments, a rounding 15 can also be present at the transitions 9.

In Fig. 12 a wet glue label embossing tool 32 for a container wet glue label 1 with an optically visible and tactilely detectable coat of arms 24 is shown as an example. This is formed with an optical field of vision 25 which stands out optically and tactilely from a surrounding area 26.

Fig. 13 shows a partial section XIII-XIII through wet glue label embossing tool 32 according to FIG Fig. 12 in the area of the optical field of view 25. The optical field of view 25 is delimited by an inner edge area 27a and an outer edge area 27b, between these edge areas 27a, 27b, for example, the container wet glue label 1 is colored, which is differentiated from the areas apart from the edge areas 27a, 27b and outside the optical field of view 25 differs. It is possible here for only one embossed contour 3a, 3b to be arranged in the edge regions 27a, 27b. This would have the consequence that the displaced contour area 7 formed between the embossing contours 3a, 3b would protrude with respect to the container, so that no large-area gluing would be possible or the gluing would have to take place with a sunken, displaced contour area 7. For the embodiment according to

Fig. 12 and 13 two embossed contours 3a, 3b or 3c, 3d are arranged in the edge areas 27a, 27b, such a pair of embossed contours 3a, 3b or 3c, 3d means that the optical field of view 25 between the edge areas 27a, 27b is not with a profile depth is formed, but is arranged at the level of the initial contour area 4, so that a good large-area gluing can take place. A contour formed in this way can then also be used for the application of additional material 28 in the optical field of view 25, for example a color, in which case the area of application of the material 28 is limited by the edge areas 27a, 27b. If a certain offset is to be accepted for an automated application of the material 28 due to tolerances, the edge areas 27a, 27b formed with the embossed contours 3a to 3d can allow the inaccuracies to be tolerated to a certain extent without the visual appearance and / or the tactile effect being significantly impaired .

It may be advantageous to use an aluminum layer in the substrate 2 (in contrast to another metallic layer or other layers). If a bottle neck film is also formed with an aluminum foil, the result is a reduced variety of materials, which is advantageous both for the manufacturing process and for the treatment of the bottle neck films and container wet glue labels that are removed during a washing process.

The labels are first produced by gravure printing, for which purpose a die 33 and male die 34 or also an embossing roller with appropriate contouring can be used. This is followed by the cutting of the container wet glue labels 1. The container wet glue labels 1 are then bound to form a stack which can then be fed to a labeling machine. The container wet-glue labels 1 can then be removed from the stack via a glue or adhesive pallet which is brought into contact with the rear side of the container wet-glue label 1. When the container wet glue label 1 adheres, it can then be removed from the stack. It is possible that a surface of the substrate 2 or container wet glue label 1 is additionally equipped with material processing, in particular embossing, with a brush design, point design or linen design.

A moistening of the container wet glue labels 1 can also take place during the filling process of the container or bottles, which u. U. takes place at high humidity. Is possible in Within the scope of the invention that the front of the container wet glue label 1 is coated with a water-impermeable layer, in particular a lacquer, so that no moisture can enter the container wet glue label 1 from the outside when the container wet glue label 1 is on the container or the Bottle is stuck on.

Paper with a thickness of 68 g / m ² or even greater thicknesses, in particular 93 g / m ² , is preferably used for the substrate 2, with deviations in particular of ± 10% from the thicknesses mentioned being possible. When using a laminate with an aluminum foil or also with the vapor deposition of aluminum, a substrate formed in this way is preferably used which has a mass of 67 or 68 g / m ² (with deviations of ± 10% also possible). It is also possible here for the substrate to have a thickness of 65 μm, and if a layer made of an aluminum foil is used, the layer thickness of the aluminum can be 6 μm.

Under certain circumstances, the application of a water-impermeable layer to the front and / or back of the substrate can be dispensed with by using the coating or the layer made of aluminum. For example, the water-impermeable layer can be used to repel condensation moisture on bottles that are still cold during the drying phase.

In a laminate, the aluminum foil is preferably used on the outside of the substrate. However, if the visual appearance of a container wet-glue label made of paper is desired, a laminate can also be used in which the aluminum foil is arranged on the inside or is arranged as an inner layer between other outer layers.

Fig. 14 shows, in a highly schematic manner and not to scale, a substrate 2 which is formed with a paper layer 29 and an aluminum layer 30. Here, the aluminum layer 30 can be vapor-deposited or formed with a laminated aluminum foil. For example, a laminate 31 with which the substrate 2 is formed has a thickness of 68 μm, the layer thickness of the aluminum layer 30 being between 5 and 9 μm.

Fig. 15 shows schematically the interaction of wet glue label embossing tools 32 in the form of a die 33 and a male die 34 with the substrate 2 arranged in between The substrate 2 is embossed as the male part 34 approaches the female part 33 until a minimal embossing gap 35 is formed between the female part 33 and the male part 34. In this case, the embossing gap 35 can have a constant or also a changing gap height, the embossing gap 35 preferably corresponding to the thickness of the substrate 2 or being smaller than this.

In Fig. 8 it can be seen that the line thickness of the embossed lettering does not have to be constant, but can also vary. Here, the embossed contour areas for forming the lateral boundaries of the line are designed independently of the line thickness of the line, while the extension of the displaced contour area changes depending on the width of the line. You can see in Fig. 8 that for a very small line thickness of the line in the end area it is even possible that no displaced contour area 7 remains, whereby it is even possible that the embossed contour areas are shortened so that they do not merge horizontally and without a kink, but rather the transition in front the distance 19 according to Fig. 9 takes place and thus a kind of "gable" is formed.

While basically for a curved lettering here Fig. 8 Embossing contour areas according to Fig. 9 Can be used, preferably for lines or numbers or lettering with a smaller size or a smaller line thickness, embossed contour areas according to Fig. 10 Commitment. Finally find the embossing contour areas according to Fig. 11 preferably used for delimiting the optical fields of view 25, in particular with two embossed contour areas which are arranged directly next to one another and oriented in opposite directions.

For the container wet glue label 1 or the substrate 2, wet and alkali-resistant label papers are preferably used, as are known per se for containers, in particular bottles such as beer bottles.

The container wet glue labels 1 or the substrate 2 are preferably a metallized, wet and alkali-proof label paper, which can have a weight of 68 g / m ² or 70 g / m ² or, alternatively, 93 g / m ² . Here u. U. the front is coated over the entire surface with a water-repellent paint, which is intended in particular to protect against condensation. For the rear side, for example, a lacquer can be used which can be designed to be water-repellent, as has also been described in particular in the applicant's patent application cited at the beginning, which was not previously published is. This lacquer can be applied partially or fully to the back. Alternatively or cumulatively, a thermosensitive lacquer can be used, which can be used in addition to stabilize the contour. It is also possible to use white, non-metallized paper.

As explained above, the contour and the contour angle resulting on the container wet glue label 1 after the embossing and before or also after the application process can u. U. deviate significantly from the contours and contour angles of the wet glue label embossing tool 32.

Figures 16-22 show embossed contours 3A with embossed contour areas 5A, as measured on a container wet glue label 1 after removal from the wet glue label embossing tool 32 formed with the die 33 and the male mold 34 or even after the container wet glue label 1 has been applied to a bottle or a container have been. In this case, the reference symbols characterizing the measured embossing contour on the container wet-glue label 1 are identified in the measurement results with the additional letter "A".

Figures 16-18 relate to embossed contours 3A, which are provided with an embossed contour area 5a according to FIG Fig. 11 are produced, for example in the edge region 27b of a coat of arms 24 according to FIG Fig. 12 . In Fig. 12 a partial area of the embossing contour is shown as an example and marked with XVI, although here it differs from Fig. 12 the course of the embossed contour areas 5a, 5b in the top view is not formed with partial straight lines connected via an angle, but this is formed in a curve shape.

In Fig. 16 it can be seen that an initial contour area 4A merges in the transition 9A into the embossed contour area 5Aa. The profile depth is at a maximum in the displaced contour area 7A. On the opposite side, the embossing contour 3A then drops off again with a corresponding embossing contour area 5Ab oriented in the opposite direction. Under certain circumstances, the starting contour area 4A with a profile depth of zero is not reached again in the area of the optical field of view 25A, but rather a material area of the container wet glue label 1 that differs from zero and is slightly displaced in the direction of the displaced contour area 7A can remain.

Figures 17 and 18 show measurement results for a detection of an embossing contour 3A when measuring along a measurement axis 36 (see FIG. Fig. 16 ). Here the profile depth is plotted in a profile depth direction 37 over the measuring axis 36. In particular, the embossing depth 6 of the displaced contour area 7A, the contour angle 14A and the extent of the embossing contour area 5A between the initial contour area 4A and the displaced contour area 7A can be taken from the measured profiles. Furthermore, according to the measurement results Figures 17 and 18 the length of the displaced contour area 7A can be taken.

Figures 19 to 22 show measured embossing contours 3A which are made with a wet glue label embossing tool 32 with an embossing contour area 5a according to FIG Fig. 9 have been manufactured. It is preferably the line of a lettering according to FIG Fig. 5 (whereby as explained differently from the description Fig. 5 a wet glue label embossing tool with an embossing contour area 5a according to FIG Fig. 9 has been used). Here show the Figures 19 and 20 Embossing contours 3A in an area of smaller line width than that Figures 21 and 22 . Here, too, a determination of the initial contour area 4A, the transitions 8A, 9A, the embossed contour areas 5A, the contour angle 14A, the length of the displaced contour area 7A and the extension of the embossed contour 3A between the initial contour area 4A and the displaced contour area 7A in the direction of the Main extension plane 13, here in the direction of the measuring axis 36. It can be seen here that the measurement curves 19, 20 differ from the courses in the area of small line widths Figures 21 and 22 for larger line widths with approximately the same embossing contour areas 5A differ by the length of the displaced contour areas 7A.

• Messungenauigkeiten,
• etwaige Vorprägungen des Behälter-Nassleimetiketts 1 vor dem Prägen in dem Nassleimetiketten-Prägewerkzeug 32,
• Imperfektionen der Dicke des Behälter-Nassleimetiketts 1 und
• sich infolge des Prägeprozesses ergebende ungleichförmige Verformungen des Behälter-Nassleimetiketts 1.

Can be seen in the Figures 16-22 a deviation of the embossing contour 3 from an "ideal" contour course in the form of elevations, depressions, curved to and fro courses, not ideally straight initial contour areas 4A and displaced contour areas 7A and the like. Ä. The cause of these deviations from an ideal course are in particular

• Measurement inaccuracies,
• any pre-embossing of the container wet-glue label 1 before embossing in the wet-glue label embossing tool 32,
• Imperfections in the thickness of the container wet glue label 1 and
• Non-uniform deformations of the container wet glue label 1 resulting from the embossing process.

Furthermore in the Figures 16-22 it can be seen that the embossing contour 3, 3A on the one hand on the wet glue label embossing tool 32 and on the other hand on the container wet glue label 1 after removal from the wet glue label embossing tool 32 and before the application of the container wet glue label 1 and after its application. In this regard, the following measurement results were obtained, for example:
I. Embossing of a lettering with the embossed contour area 5 according to Fig. 9 : Embossing contour of the wet glue label embossing tool Embossing contour of the container wet glue label after removal from the wet glue label embossing tool and before it is applied to the bottle Embossing contour of the container wet glue label after it has been applied to the bottle Maximum embossing depth in the relocated contour area 0.200 mm - 0.260 mm 0.050mm - 0.100mm 0.060mm - 0.110mm Contour angle 48 ° - 52 ° 13 ° - 17 ° 9 ° - 22 ° Extension of the embossed contour area between the displaced contour area and the initial contour area in the direction of the main extension plane 0.300mm - 0.400mm 0.270mm - 0.380mm 0.250mm - 0.600mm
II. By contrast, for an embossing process of a container wet glue label 1 with an embossing contour area 5 according to FIG Fig. 11 , in particular for an optical field of view for a coat of arms or similar, the following embossing contours were measured: Embossing contour of the wet glue label embossing tool Embossing contour of the container wet glue label after removal from the wet glue label embossing tool and before it is applied to the bottle Embossing contour of the container wet glue label after it has been applied to the bottle Maximum embossing depth in the relocated contour area 0.190mm - 0.230mm 0.090mm - 0.150mm 0.085mm - 0.115mm Contour angle 48 ° - 52 ° 14 ° - 20 ° 12 ° - 18 ° Extension of the embossed contour area between the displaced contour area and the initial contour area in the direction of the main extension plane 0.250mm - 0.280mm 0.400mm - 0.510mm 0.400mm - 0.480mm

It can be seen from these measurement results that the resulting maximum profile depth of the displaced contour area 7 on the container wet-glue label 1 after removal from the wet-glue label embossing tool 32 and / or after application to the bottle is less than half the maximum embossing depth of the wet-glue label embossing tool 32 is. The contour angle 14A is less than a third of the contour angle 14 of the embossing contour area 5 of the wet glue label embossing tool 32. The extent of the embossing contour area between the displaced contour area and the starting contour area is on the container wet glue label 1 after removal from the wet glue label embossing tool 32 and / or after the application of the same to the wrong one is greater than this extension on the wet glue label embossing tool 32. It can also be seen that u. U. with an increase in the extent of the displaced contour area 7A, the fluctuations in the contour (cf. Figs. 21, 22 ) become larger in the displaced contour area 7A.
