Description

METHOD AND DEVICE FOR LABELING CONTAINERS WITH A ROUNDUMETIC LABEL AND AROUND THE LUMINAIRE LABEL AND CONTAINER Description

The present invention relates to a method and apparatus for labeling containers with a wrap-around label, as well as a wrap-around label and a container. The wrap-around label is made of a rigid material, in particular cardboard, and in particular has at least one self-locking element which produces a self-locking connection with the container.

Containers, such as bottles, cans, etc., are treated in container treatment plants in such a way that the containers are prepared for receiving a product and / or are already filled with a product. Such a product is, for example, a food, a liquid such as a drink, a detergent, a cosmetic product, etc., a paste such as a cosmetic product, etc., a piece goods such as a cloth, bars, etc. Alternatively or additionally the containers in the container treatment plant are packed in packaging units.

To mark the products in the containers, the containers are provided with a label. Currently, labels are attached to the containers with adhesive. In addition, a wrap-around label, which is cut off from a roll in particular for labeling the container, is fixed to a container and at its two ends with adhesive. Conventional labeling techniques are suitable for mass production and can be used for production in an automatic production line. Depending on the type of label, however, the labeling techniques require certain geometrical requirements on the part of the containers and a relatively high expenditure on material and / or energy for applying a label to the container. For wrap-around labels, preferably cylindrical areas of the bottle can be labeled. In a sleeve-shaped label, a comparatively high amount of material and energy is required, since a lot of glue is required, especially for large adhesive labels. In addition, a separation of container and label in a recycling stream is often very complicated or not completely possible. In addition, containers that are printed instead of a glued label in the production line in direct printing, are only very limited recyclable. All of these labeling variants mean that the containers, after their disposal, can usually only be used for thermal recycling, at least not again as containers. Therefore, it is an object of the present invention to provide a method and an apparatus for labeling containers with a wrap-around label and a wrap-around label and a container with which the aforementioned problems can be solved. In particular, methods and an apparatus for labeling containers with a wrap-around label as well as a wrap-around label and a container are to be provided in which a labeled container with little effort is environmentally friendly to produce and can be recycled easily and inexpensively.

This object is achieved by a method for labeling a container with a wrap-around label according to claim 1. The wrap-around label is formed from a rigid material that is different from the material of the container. The method comprises the steps of fixing the wrap-around label to an adhesive on the container, and forcing at least one self-locking element of the wrap-around label into a recess of the container so that the at least one self-locking element forms a self-locking connection with the container which seals the label on the container Container holds.

The described method is designed such that only a very small amount of adhesive and an easily dissolvable adhesive can be used for the label, since a partially foldable label with a depression in the container geometry is fixed on the container in such a way that a self-locking connection between the container and the label results , As a result, the adhesive for recycling the container can be easily detached from the container. As a result, recycling the container is significantly less expensive and therefore less expensive than before.

In addition, the described method has the advantage that the label brings about a stabilizing effect for the container. As a result, the container can be produced with a very small wall thickness, which minimizes the consumption of resources.

The method produces a defined combination of container and label, wherein the container is, for example, a container made of plastic.

In addition, the cost-effective and time-effective nature of the labeling carried out with the method allows a significant expansion of the spectrum of usable container geometries. In addition to a better handling of the container by a user, the label also makes possible a large advertising and information area.

As a further advantage, the method entails that the label can protect a photosensitive product in the container against light radiation. Thus, the container-label composite is an alternative to beverage cartons provided with a liquid-tight coating used, for example, to package milk, juice, etc.

Advantageous further embodiments of the method are specified in the dependent claims.

The step of securing the wrap-around label may include: securing a first end of the wrap-around label to an adhesive on the container, wherein the adhesive has a greater adherence force to the wrap-around label than to the container, placing the wrap-around label around the container to provide the wrap-around label a second end of the wrap-around label overlaps a portion at the first end, fixing the wrap-around label in the region of the second end with the adhesive at the first end.

In one embodiment, the wrap-around label in the region of the second end is provided with the adhesive such that an area free of the adhesive remains on which the wrap-around label for separating the wrap-around label from the container can be gripped. It is also conceivable that the adhesive is a hot melt having a viscosity of 1100 to 1700 Pa s and a processing temperature of 140 ° C to 150 ° C.

It is possible that the adhesive is applied to the wrap-around label with a roller or a die.

According to a variant, the wrap-around label may be provided in a device for labeling the container as a finished label by means of a label providing unit designed as a roll or magazine.

In a special embodiment, the wrap-around label is made of a cellulose material and the container is made of a plastic.

The aforementioned object is also achieved by a device for labeling a container with a wrap-around label according to claim 8. The apparatus has a label providing unit for providing a wrap-around label so that the containers are endowed with a wrap-around label one after another, the wrap-around label being formed of a rigid material that is different from the material of the container, and a pressing unit for pressing the wrap-around label in a region of a recess of the container to the container, so that at least one self-locking element of the wrap-around label with the container forms a self-locking connection that holds the label to the container.

According to one embodiment, the pressing unit has a sponge roller, which is designed to press the wrap-around label into the recess. Additionally or alternatively, the pressing unit is designed as a retaining clip or contour of a transport device. Additionally or alternatively, the pressing unit has a clamping element for pressing the wrap-around label into the depression. Additionally or alternatively, the pressing unit is an active actuator, which is designed to press the wrap-around label into the recess.

The aforementioned object is also achieved by a wrap-around label according to claim 10. The wrap-around label has a first end at which there is provided an area where the wrap-around label is to be affixed to a container with adhesive, a second end to be placed over the area when the wrap-around label is affixed to the container, at least a self-locking element configured to form with the container a self-locking connection that holds the label to the container, wherein the Label is formed of a rigid material that is different from the material of the container.

In one embodiment, the wrap-around label also has at least one tear site, which is designed as a perforation and / or as a cut, with the self-locking element forming at the tear site.

The aforementioned object is also achieved by a container according to claim 12. The container has a container mouth for filling a product into the container, a label which encloses the container in a region other than the container mouth, wherein the label is formed of a rigid material which is different from the material of the container, and at least one recess with which at least one self-locking element of the label forms a self-locking connection that holds the label to the container.

The container may have a square-round cross-section. Additionally or alternatively, the container is a bottle.

The device, the wrap-around label, and the container each provide the same advantages as previously referred to in the method.

Further possible implementations of the invention also include not explicitly mentioned combinations of features or embodiments described above or below with respect to the exemplary embodiment. The skilled person will also add individual aspects as improvements or additions to the respective basic form of the invention.

In the figures, identical or functionally identical elements are provided with the same reference numerals, unless stated otherwise. Fig. 1 shows a container 3 according to a first embodiment. The container 3 is designed as a bottle. The container 3 has a container mouth 31 and a bottom 32, which are connected by a container wall 33. In the container wall 33 recesses 34 and beads 35 are provided, each contributing to the stiffening of the container wall 33. The beads 35 protrude out of the container wall 33 to the outside. The recesses 34 project into the container wall 33 inwardly. The recesses 34 narrow the maximum cross section of the container 3 approximately in the middle of its container wall 33. The container 3 is constructed symmetrically to a container axis 36. According to FIG. 2, the container 3 has at its bottom 32 an approximately square cross-section with rounded container corners 321. In approximately square cross-section means that the walls of the container 3 are arched between the corners 321 to the outside. In this case, the walls are curved with a larger radius than the container corners 321. As a result, the cross section of the bottom 32 in each case in the middle of the approximately square sides its maximum cross-section D. Therefore, the cross section of the bottom 32 as square-round or square designated round. With the exception of the recesses 34 and in the transition to the container mouth 31, the entire container 3 has the same cross section as the bottom 32, as well as from the synopsis with FIG. 1 recognizable. The advantage of such a container 3 is that the container 3 is easily stackable but at the same time also labeled with a similar effort as a container with a round or oval cross section and can be labeled.

The container 3 rests only in the region of a circumferential bottom ring 322 on the bottom 32 on a base, not shown. Otherwise, the bottom 32 is curved in the direction of the container axis 36 inwards in the direction of the container mouth 31, in particular into the region on which the lowermost bead 35 is arranged on the container wall 33. Between the bottom ring 322 and a bottom center 323 in the container axis 36 transverse struts 324 are provided. The bottom ring 322, the bottom center 323 and the cross braces 324 contribute to the stiffening of the bottom 32 of the container 3. In addition, the above-described embodiment of the bottom 32 increases the stability of the container 3 with the bottom 32 on a base. For stability reasons, the material thickness of the bottom 32, as well as the material thickness of the Area of the container mouth 31, the so-called container head, are chosen to be thicker than the material thickness of the container wall 33, to which a label 4 described below is attached. As shown in Fig. 3 in a cross section of the container 3, the container 3 can be provided in a method for labeling the container 3 with a wrap-around label 4. The cross-section of the container 3 shown in Fig. 3 is in the region between the recesses 34 and the bottom 32 of the container 3. The label 4 is shown in more detail in Fig. 4 in its development.

From a synopsis of Fig. 3 and Fig. 4 it can be seen that the wrap-around label 4 rests with its first end 41 to the container 3 when the container 3 is labeled with the label 4. After attaching the first end 41 to the container 3 with an adhesive 5, which is shown very schematically in Fig. 4, the label 4 is mounted around the container 3 until the label 4 is arranged along its length to the container 3. According to Fig. 4, the label 4 is subdivided in length by first folds 43A to 43D and optionally by second folds 44A to 44D. The folds 43A to 43D, 44A to 44D are executable as fold lines. 3 and 4, the two ends 41, 42 of the label 4 overlap in a first end region 45 having a predetermined width B and a second end region 46 disposed between the second end 42 and the fold 43D. In the second end region 46 and / or the first end region 45, the two ends 41, 42 can be fastened together with adhesive 5. At the second folding locations 44A to 44D, two third folding locations 47 are respectively provided which allow the label 4 to abut the contour of the container 3 at the recess 34 when the label 4 is pressed into the recesses 34 of the container when the label 4 is pressed 3 tears along at least one crack point 48 or unfolds. The at least one fracture point 48 is arranged transversely to the second fold locations 44A to 44D. The at least one crack point 48 can be produced with a perforation and / or cut of any desired configuration. The perforation can tear only by pressing the label 4 in the associated recess 34. Alternatively, the perforation may have already severed the at least one tear site 48 before the label 4 is pressed into the associated recess 34. The at least one break point 48 is, for example, a tear line that can be straight and / or at least partially bent, wherein sections of the tear line can be arranged at a predetermined angle to one another. The area between two third folds 47 and a tear point 48 forms a self-locking element 471 which fixes the label 4 to the container 3 in the associated recess 34. Optionally, a region 49 free of adhesive 5, which may also be referred to as a non-glued region, may be provided in the form of a corner on the label 4. In general, the area 49 has such a shape and size that the label 4 in the area 49 is easily graspable, so that the label 4 for recycling can be easily separated from the container 3 later.

Thus, the label 4 is partially foldable, namely in the specific example of Fig. 4 at the first to third folds 43A to 43C, 44A to 44D, 47 and optionally only at one of the fractures 48, if only one of the two fractures 48 when pressed tears into the recess 34. As a result, the label 4 is arranged in the depressions 34 of the container 3 such that a self-locking connection between the container 3 and the label 4 forms with the at least one self-locking element 471. The fixation or the adhesive 5 between container 3 and label 4 may or may already come loose again from the container 3 when the self-locking connection between the container 3 and the label 4 is formed. The adhesive 5 may therefore have an adhesion force that is greater than the adhesion force to the container 3 to the label 4.

Such an adhesive 5 is in particular a peelable hot glue, which is built up on a granular basis. It is advantageous if the hot glue has a food approval, so that the hot glue is also suitable or suitable for container 3, are filled into the food as a product. Here, the adhesive 5 is, for example, a hot glue currently available from Toyo ADL Corporation, Tokyo, Japan, having a viscosity of 1100 to 1700 Pa · s and a processing temperature of 140 ° C. to 150 ° C., but not more than 170 ° C is processable. The application of such a hot glue is possible with a hot melt roller. Alternatively, such a hot glue may be applied to the label 4 with a hot melt application die.

Such an adhesive 5 allows a relatively fiber-free separation of the composite label 4 and container 3. Thus, such adhesive 5 remains when separating the label 4 of the container 3 to 100% adhere to the label 4. As a result, a container-to-container recycling is possible for the container 3.

In the container 3, the recesses 34 are formed such that the recesses 34 form recessed grips, where the container 3 with the hand of a user is easily accessible. Thus, the container 3 with the recesses 34 and the correspondingly formed areas of the label 4 also has an integrated handle function. The container 3 and the label 4 thus form a defined combination. Here, the container 3 and the label 4 are matched in shape and design to each other that the container 3 and the label 4 are positively connected when the label 4 is attached to the container 3, as illustrated in Fig. 3, and the container

3 is thus labeled with the label 4. However, the label 4 can be removed from the container 3 without residue if the positive connection between container 3 and label

4 should be solved. The label 4 thus forms a detachable jacket for the container 3.

The label 4 is made of a rigid material, such as cellulose material, in particular paper or cardboard. The material, such as the cellulosic material, for example, has a weight of 100 to 500 grams per square meter, in particular a weight of 200 to 300 grams per square meter. The label 4 of Fig. 3 has as a specific example as a material a carton weighing 190 grams per square meter. However, it is of course conceivable another weight per square meter. The wall thickness of the label 4 may, for example, be in a range of from 40 μηη to 50 μηη inclusive. The material for the label 4 thus has a different material than the container 3. The cell material is in contrast to the material of the container 3 is a thermally stable material. The material for the label 4 is freely selectable insofar as the label 4 can fulfill the function as described above and below. Fig. 5 shows a container treatment plant 1 for the treatment of containers 3, which can be bottles, cans, boxes, etc., which can be equipped with the label 4 of Fig. 4 and, if desired, with any printing as a label. However, it is possible that the label 4 is already completely provided with a final marking. For example, the throughput of such a container treatment plant 1 for the containers 3 of FIG. 1 to FIG. 3 with labels 4 according to FIG. 4 is 40,000 containers per hour.

For this purpose, the container treatment plant 1 as an example, a first to third container treatment apparatus 10, 20, 30, which are coupled to each other via transport means 40, 50. The coupling of the container treatment device 10, 20, 30 is possible, for example, via a blocked variant of the container treatment devices 10, 20, 30. The However, the container treatment apparatus 1 and the container treatment apparatuses 10, 20, 30 are not limited thereto and may alternatively be strung together in a separate form. The container treatment system 1 may alternatively have only one or two or more than the three container treatment devices 10, 20, 30. As a result, any number of container treatment devices 10, 20, 30 is possible. In Fig. 5, not all containers 3 are shown or provided with a reference numeral for the sake of simplicity.

A container 3 is in particular a container 3 according to FIG. 1. Such a container 3, for example, a capacity of a maximum of about 0.33 liters or 0.5 liters or 1, 5 liters, etc. have. Of course, other capacities are conceivable. In this case, the shape of the container 3 is freely selectable under the conditions mentioned above and below. The container 3 may alternatively have a circular or oval cross-section, which is provided with at least one recess 34 in the container wall, with which the described self-locking connection between container 3 and label 4 can be formed. In addition, the material of the container 3 is freely selectable, such as glass, plastic, aluminum, etc. The plastic is in particular polyethylene terephthalate (PET). However, if necessary, alternatively or additionally other plastic materials can be used. In addition, the container 3 may be formed of a transparent plastic or a colored plastic.

The first container treatment apparatus 10 is, for example, a stretch blower having a heater for heating preforms to an appropriate temperature to form the containers 3 according to the example of FIG. 1. The containers 3 are fed to the second container treatment device 20 via the transport device 40, which transfers the containers 3 to the second container treatment device 20 by means of an inlet star. The second container treatment device 20 is a device for labeling the container 3 with the label 4 or a similar container with recesses 34 with a label 4 with comparable properties. This will be described in more detail below.

The transport device 50 takes over the containers 3 again by means of an outlet star and transports the containers 3 to the third container treatment device 30, which is for example a filling device. In the filling device, the container 3 filled with a product which is in particular a liquid and / or a food and / or a photosensitive product, etc.

As an alternative to the above-described special arrangement of the container treatment devices 10, 20, 30, in particular a block combination of the devices 10, 20, 30 is possible and / or an arrangement in which a filling device is followed by an equipment device in the form of a labeling device and / or printing device , As already mentioned, other combinations of container treatment devices 10, 20, 30 with transport devices 40, 50 are of course possible. In particular, a combination with a capper for closing the container 3 after filling, a cleaning device for cleaning the container 3, a packaging machine for packaging the container 3 in the desired packaging unit, an inspection device for inspection of the container 3 for errors, etc. conceivable.

The direction of transport TR of the containers 3 is indicated in each case by arrows in FIG. 5 and also results from the row of containers 3 along the container treatment devices 10, 20, 30 and the transport devices 40, 50. The transport devices 40, 50 can be additional transport rails or multifunctional stars or carousels for transporting the container 3 have. It is also possible that at least one of the container treatment devices 10, 20, 30 is designed as a multifunction star or carousel or has such. In the example of FIG. 5, the second container treatment device 20 as the labeling device is an equipment device that provides the container 3 treated by the first container treatment device 10 with a mark. The marking is for example the label 4 and / or any printing. For this purpose, the equipment device in the example of Fig. 5 has four different modules 21 to 24 and at least two pressure units 25. For example, the module 21 is a labeling and / or printing unit in which the labels 4 are provided by a label providing unit 21 1, the is carried out as a roller 21 1, from which the label 4 is cut off by mistake with the adhesive 5 with a cutting unit. The module 22 is a labeling unit, in which the labels 4 are provided by a supply unit 221, which is designed as a roll. After the modules 21, 22 each have a fixing unit 29 is provided, which is executable as a sponge plate or sponge roll. The fixing unit 29 serves to attach the label end 43D to fix the label beginning or first end of the label 41 after the label 4 has been transferred from a vacuum cylinder to the container 3.

The modules 21, 22 also include an unspecified unit for applying the adhesive 5 on the label 4. The modules 23, 24 are formed as printing units, which are optionally available. With the pressing units 25, the label 4 is pressed at the at least one crack point 48 per recess 34 in the wells 34 of the container 3 and thereby fixed to the container 3 self-locking and then held with the self-locking elements 471 on the container 3.

As shown in Fig. 6, the pressing units 25 each have a sponge roller 251 which is rotatable about an axis 252. Optionally, the sponge roller 251 is spring-loaded in order to be able to control the contact pressure on the container 3 in a particularly simple manner. The sponge roller 251 is movable to the container 3, in particular pivotable, as illustrated by the bidirectional arrow in Fig. 5 and in Fig. 6. In this way, the label 4 can be pressed into the recess 34 in the region of the at least one crack point 48. The sponge roller 251 is adapted in its outer contour to the geometries of the recess 34 of the container 3. As a result, the self-locking fixation of the label 4 by means of the at least one self-locking element 471 on the container 3 is very advantageously supported and executed effectively.

For simplicity, other components of the second container treatment device 20, such as in particular print heads, sensors, drive means for label rolls, etc. are not shown and described.

In the container treatment apparatus 20 according to FIG. 5, in the method for labeling the container 3, the containers 3 are labeled with the ready-prepared label 4 from the roll. Here, the label 4 is provided at its ends 41 and 42 respectively with the adhesive 5, as previously described in more detail with reference to FIG. 3 and FIG. 4. For this purpose, a roller or a nozzle can be used, which may be provided in the modules 21, 22. After being supplied to a container 3, the label 4 is first applied with its first end 41 on the outside of the outer wall of the container 3 and fixed thereto with the adhesive 5, as described in more detail above with reference to FIG. 3 and FIG. Thereafter, the container 4 is rotated about its container axis 36 until the label 4 can be placed with its second end 42 on the first end 41, as shown in Fig. 3 in section. Subsequently, the container 3 provided with the label 4 is transported to one of the pressing units 25 in order to provide the self-locking connection between Container 3 and label 4, as described above. In this case, the container 3 with the label 4 fixed thereto is rotated about its container axis 36, so that each of the pressing units 25 can successively press the label 4 into at least two different recesses 34 of the container 3 to produce the positive connection between container 3 and label 4. If three pressure units 25 are provided for each of the depressions 34 of the container 3, the container 3 is to be rotated about its container axis 36 on the way between the pressure units 25.

The label 4 is thus a hot glue label from the roll, the label 4 being a prefabricated label. Alternatively, or to an additional printing of the label 4, the module 21 as a labeling and / or printing unit also at least partially print directly on the container 3. However, the latter is currently rather disadvantageous with regard to the recyclability of the container 3. In particular, with the labeling and / or printing unit or the printing units with a printer, such as an inkjet or laser printer, an additional marking on the labels 4 and / or 3 containers are printed to ensure traceability of the container 3 and / or products , There are any combinations of modules 21 to 24 as equipment modules and thus varieties of labels, especially labels, conceivable and feasible.

Alternatively, however, the modules 21 to 24 may each be configured identically so that all the containers 3 are provided with the same type of markings, in particular only the labels 4. As a result, the label 4 in the container 3 has not only a function as an advertising or data surface. In addition, the label 4 has the function of contributing to the stability of the overall packaging of the product in the container 3, the said handling function and the aforementioned light protection for the product. From the stability function, there is also the effect that the stability of the container 3 without label 4 may be lower due to a reduced container wall thickness than in a conventional container 3. Through the recesses 34 in the container 3 and the special folds 43A to 43D and 44A to 44D or folds of the label 4 result in defined gripping surfaces, which facilitate the handling of the container 3 for the user. Due to the low use of adhesive 5 and the special adhesive 5, the label 4 is easily separable from the container 3 and can therefore already in the end user properly in the recyclables plastic or glass, etc. for the container 3 and Cellulosic material for the label 4 separated and thus the appropriate recycling cycles are supplied.

In a modification of the apparatus 20, at least one of the modules 21, 22, instead of the label providing unit (s) 21 1, 221, which provide the labels 4 by means of label rolls and associated cutting mechanism, has a magazine which provides the labels 4. The magazine can be assigned two hot glue units, wherein one of the hot melt units is connected upstream of the magazine in the transport direction TR of the container 3 and the other of the hot melt units is downstream of the magazine in the transport direction TR of the container 3.

FIGS. 7 and 8 illustrate a pressing unit 51 according to a second embodiment. The pressing unit 51 is provided as a clamping element of the transport device 50, in particular in its outlet star. The pressing unit 51 has a first bracket 51 1 and a second bracket 512, which face each other, so that the container 3 between the brackets 51 1, 512 can be accommodated. The brackets 51 1, 512 are adapted in their shape and arrangement to the recesses 34 of the container 3. Accordingly, in the example of FIGS. 7 and 8, the clamps 51 1, 512 are configured and arranged such that the clamps 51 1, 512 of two approximately mutually parallel sides of the container 3 on the depressions 34 in the container 3 can grab. The clamps 51 1, 512 can be fed to one another by means of a spring 515 on clamping jaws 513, 514.

The depressions 34 of a container 3 need not be arranged in the middle of the container 3. The wrap-around label 4 is designed accordingly. It is not mandatory that the label 4 in a container 3 covers the container wall 33 in the entire length between the container bottom 32 and the container head in the region of the container mouth 31. Thus, the crack sites 48 and third folds 47 and the at least one self-locking element 471 may be disposed at an arbitrary position between the edges of the label 4. In particular, it is also conceivable to provide at least one self-locking element 471 on the edge of the wrap-around label 4. However, a self-locking member 471 disposed in an area between the outer edges of the label 4 will be less likely to be detachable from the container 3 unintentionally than a self-locking member 471 at the edge of the wrap-around label 4.

It is also conceivable that the label 4 is prefolded and glued and placed in the second container treatment device 20 on the container 3 similar to a sleeve label or sleeve-shaped label and then fixed on the described Andrückmöglichkeiten.

The equipment device 20 may have any combination of the pressing units 25, 26, 27, 51, 52, 56, 60 according to the first to seventh embodiments.
