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 protect a photosensitive product in the container against light radiation can. 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 adhesion 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 member configured to form with the container a self-locking connection that holds the label to the container, the label being formed from 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.

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 floor 32 passing through a container wall 33 are connected. In the container wall 33 are depressions 34 and beads 35 provided, each for stiffening the container wall 33 contribute. The beads 35 protrude from the container wall 33 outwards. The wells 34 protrude into the container wall 33 inside. The wells 34 narrow the maximum cross-section of the container 3 approximately in the middle of its container wall 33 , The container 3 is to a container axis 36 symmetrically constructed.

According to 2 the container has 3 at its bottom 32 an approximately square cross-section with rounded container corners 321 , In approximately square cross-section means that even the walls of the container 3 between the corners 321 are arched outwards. Here, the walls are curved with a larger radius than the container corners 321 , This has the cross section of the soil 32 each in the middle of approximately square sides its maximum cross-section D , Therefore, the cross section of the soil 32 also referred to as square-round or square-round. Except for the depressions 34 and in the transition to the container mouth 31 has the entire container 3 the same cross-section as the ground 32 , as well as from the synopsis with 1 recognizable. The advantage of such a container 3 is that the container 3 easily stackable but at the same time with similar effort as a container with a round or oval cross section and can be labeled clearly defined.

The container 3 only in the area of a circumferential bottom ring 322 on the ground 32 on a not shown on pad. Otherwise, the floor 32 in the direction of the container axis 36 inward towards the container mouth 31 arched, in particular to the area where the lowest bead 35 on the container wall 33 is arranged. Between the bottom ring 322 and a bottom center 323 at the container axis 36 are cross struts 324 intended. The bottom ring 322 , the bottom center 323 and the cross braces 324 contribute to the stiffening of the soil 32 of the container 3 at. In addition, the previously described embodiment of the floor increases 32 the stability of the container 3 with the ground 32 on a pad. For stability reasons, the material thickness of the soil 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 described below 4 is attached.

As in 3 in a cross section of the container 3 shown, the container can 3 in a method for labeling the container 3 with a wrap-around label 4 be provided. The in 3 shown cross section of the container 3 lies in the area between the depressions 34 and the floor 32 of the container 3 , The label 4 is in 4 shown in detail in his transaction.

From a synopsis of 3 and 4 it can be seen that the wrap around label 4 with his first end 41 on the container 3 is present when the container 3 with the label 4 is labeled. After attaching the first end 41 on the container 3 with an adhesive 5 , this in 4 is shown very schematically, the label 4 all around the container 3 attached to the label 4 its length on the container 3 is arranged. According to 4 is the label 4 its length by first folds 43A to 43D and optionally by second folds 44A to 44D divided. The folds 43A to 43D . 44A to 44D are executable as fold lines. According to 3 and 4 overlap the two ends 41 . 42 of the label 4 in a first end area 45 with a predetermined width B and a second end region 46 that is between the second end 42 and the fold 43D is arranged. In the second end area 46 and / or the first end region 45 are the two ends 41 . 42 with adhesive 5 attachable to each other. At the second folds 44A to 44D each are two third folds 47 provided that allow the label 4 to the contour of the container 3 at the recess 34 applies when the label 4 when pressing in the label 4 into the wells 34 of the container 3 along at least one crack site 48 tears or opens. The at least one crack 48 is transverse to the second folds 44A to 44D arranged. The at least one crack 48 Can be produced with a perforation and / or cut of any configuration. The perforation can only be done by pressing the label 4 into the corresponding depression 34 rip. Alternatively, the perforation may be the at least one fracture site 48 have already severed before the label 4 into the corresponding depression 34 is pressed. The at least one crack 48 is for example a tear line, which may be rectilinear and / or at least partially bent, wherein portions of the tear line may be arranged at a predetermined angle to each other. The area between two third folds 47 and a crack site 48 forms a self-locking element 471 which the label 4 on the container 3 in the corresponding recess 34 fixed.

Optionally, one of adhesives 5 free area 49 , which may also be referred to as unprimed area, in the form of a corner on the label 4 be provided. In general, the area has 49 Such a shape and size that the label 4 in that area 49 is easily accessible to the label 4 for recycling later easily from the container 3 to be able to disconnect.

Thus, the label 4 partially foldable, namely in the specific example of 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 cracks 48 when pressing into the depression 34 tears. This will make the label 4 so in the wells 34 of the container 3 arranged that with the at least one self-locking element 471 a self-locking connection between the container 3 and the label 4 forms. The fixation or the adhesive 5 between containers 3 and label 4 can or may already be back from the container 3 solve if the self-locking connection between the container 3 and the label 4 is formed. The adhesive 5 may therefore have an adhesive power to the label 4 is greater than the adhesion to the container 3 ,

Such an adhesive 5 is in particular a peelable hot glue, which is based on granules. It is advantageous if the hot glue has a food approval, so that the hot glue for containers 3 is suitable or suitable to be filled into the food as a product. Here is the adhesive 5 For example, a hot melt, which is currently available from Toyo ADL Corporation, Tokyo, Japan and has a viscosity of 1100 to 1700 Pa s and at a processing temperature of 140 ° C to 150 ° C, but a maximum of 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 with a hot melt application nozzle 4 be applied.

Such an adhesive 5 allows a relatively fiber-free separation of the composite label 4 and containers 3 , This leaves such an adhesive 5 when separating the label 4 from the container 3 100% on the label 4 be liable. This is for the container 3 a container-to-container recycling possible.

At the container 3 are the depressions 34 formed such that the recesses 34 Form recessed handles on which the container 3 with the hand of a user is easily accessible. Thus, the container has 3 with the wells 34 and the correspondingly formed areas of the label 4 also an integrated handle function.

The container 3 and the label 4 thus form a defined combination. Here are the container 3 and the label 4 matched in shape and design to each other so that the container 3 and the label 4 are positively connected when the label 4 on the container 3 attached, as in 3 illustrated, and the container 3 thus with the label 4 is labeled. The label 4 but can be left without residue from the container 3 be removed again when the positive connection between container 3 and label 4 to be solved. The label 4 thus forms a detachable sheath 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 from 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 For example, it can range from 40 μm to 50 μm inclusive.

The material for the label 4 thus has a different material than the container 3 , The cell material is different from the material of the container 3 a thermally dimensionally stable material. The material for the label 4 is optional insofar as the label 4 can perform the function as described above and below.

5 shows a container treatment plant 1 for the treatment of containers 3 which can be bottles, cans, boxes, etc., with the label 4 from 4 and, if desired, can be equipped with any printing as a marking. It is possible, however, that the label 4 already completely provided with an end marking. For example, the throughput of such a container treatment plant 1 for the containers 3 from 1 to 3 with labels 4 according to 4 at 40 .000 containers per hour.

For this purpose, the container treatment plant 1 as an example, a first to third container treatment device 10 . 20 . 30 on, with each other via transport facilities 40 . 50 are coupled. The coupling of the container treatment device 10 . 20 . 30 is for example about a blocked variant of the container treatment devices 10 . 20 . 30 possible. The container treatment plant 1 and the container treatment devices 10 . 20 . 30 however, are not limited thereto and may alternatively be strung together in a separate execution.

The container treatment plant 1 alternatively, only one or two or more than the three container treatment devices may be used 10 . 20 . 30 exhibit. Accordingly, any number of container handling devices 10 . 20 . 30 possible. In 5 For the sake of simplicity, not all containers are 3 represented or provided with a reference numeral.

A container 3 is in particular a container 3 according to 1 , Such a container 3 For example, it may have a capacity of no more than about 0.33 liters or 0.5 liters or 1.5 liters, and so on. Of course, other capacities are conceivable. Here is the shape of the container 3 freely selectable under the conditions mentioned above and below. The container 3 may alternatively have a circular or oval cross section with at least one recess 34 is provided 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 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 can 3 be formed of a transparent plastic or a colored plastic.

The first container treatment device 10 For example, a stretch blower having heating means for heating preforms to an appropriate temperature around the containers 3 according to the example of 1 to shape. The containers 3 become the second container treatment device 20 about the transport device 40 fed to the containers 3 by means of an inlet star to the second container treatment device 20 passes. 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 containers 3 filled with a product which is in particular a liquid and / or a food and / or a photosensitive product, etc.

Alternatively to the special arrangement of container treatment devices described above 10 . 20 . 30 is in particular a block combination of the devices 10 . 20 . 30 possible and / or an arrangement in which a filling device downstream of a fitting device in the form of a labeling and / or printing device. Of course, as previously mentioned, other combinations of container handling devices are contemplated 10 . 20 . 30 with transport facilities 40 . 50 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 packing the containers 3 in the desired packaging unit, an inspection device for inspection of the container 3 on mistakes, etc. conceivable.

The transport direction TR the container 3 is in 5 each indicated by arrows and also results from the series of containers 3 along the container treatment devices 10 . 20 . 30 and the transport facilities 40 . 50 ,

The transport facilities 40 . 50 can use additional transport rails or multi-function stars or carousels to transport the containers 3 exhibit. 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 5 is the second container treatment device 20 as a device for labeling, a fitting device which is the one of the first container treatment device 10 treated container 3 equipped with an identification. The label is for example the label 4 and / or any printing. For this purpose, the equipment device in the example of 5 four different modules 21 to 24 and at least two pressing units 25 , For example, the module is 21 a labeling and / or printing unit, wherein the labels 4 from a label providing unit 211 be provided as a role 211 is executed, from which the label 4 after using the adhesive 5 is cut off with a cutting unit. The module 22 is a labeling unit in which the labels 4 from a provisioning unit 221 be provided, which is designed as a role. After the modules 21 . 22 each is a fuser unit 29 provided, which is executable as a sponge plate or sponge roll. The fuser 29 serves to the label end 43D at the beginning of the label or first label end 41 to fix after the label 4 from a vacuum cylinder to the container 3 was handed over.

The modules 21 . 22 Also include an unspecified unit for applying the adhesive 5 on the label 4 , The modules 23 . 24 are designed as printing units, which are optionally available. With the pressure units 25 becomes the label 4 at least one crack site 48 per well 34 into the wells 34 of the container 3 pressed and thereby on the container 3 self-locking fixed and then with the self-locking elements 471 on the container 3 held.

As in 6 shown, have the pressure units 25 one sponge roll each 251 around an axis 252 is rotatable. Optional is the sponge roll 251 sprung to the contact pressure to the container 3 particularly easy to control. The sponge roll 251 is to the containers 3 movable, in particular pivotable, as with the bidirectional arrow in 5 and in 6 illustrated. This can be the label 4 in the area of at least one crack site 48 into the depression 34 be pressed. The sponge roll 251 is in its outer contour to the geometries of the recess 34 of the container 3 customized. This will be the self-locking fixation of the label 4 by means of the at least one self-locking element 471 on the container 3 supported very beneficial 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. not shown and described.

In the container treatment device 20 according to 5 be in the process of labeling the container 3 the containers 3 with the ready-made label 4 labeled from the roll. Here is the label 4 at its ends 41 and 42 according to the adhesive 5 provided as described above 3 and 4 described in more detail. For this purpose, a roller or a nozzle can be used, which in the modules 21 . 22 can be provided. After feeding to a container 3 becomes the label 4 first with his first end 41 outside to the outer wall of the container 3 put on and with the adhesive 5 fixed as before with respect to 3 and 4 described in more detail. After that, the container becomes 4 around its container axis 36 so turned up to the label 4 with his second end 42 on the first end 41 can be placed as in 3 shown in section. Subsequently, the one with the label 4 provided containers 3 to one of pressure-applying units 25 transported to the self-locking connection between containers 3 and label 4 as described above. This is the container 3 with the label attached to it 4 around its container axis 36 rotated so that each of the pressure units 25 the label 4 successively in at least two different wells 34 of the container 3 can push to the positive connection between container 3 and label 4 manufacture. Are for each of the wells 34 of the container 3 pressure-applying units 25 provided is the container 3 on the way between the pressure units 25 around its container axis 36 to turn.

The label 4 is thus a hot glue label from the roll, with the label 4 a pre-made label. Alternatively or for additional printing on the label 4 can the module 21 as a labeling and / or printing unit also at least partially directly on the container 3 To Print. The latter, however, is in relation to the recyclability of the container 3 currently rather disadvantageous. 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 containers 3 be printed to trace the container 3 and / or products. They are any combinations of modules 21 to 24 as equipment modules and thus varieties of markings, in particular labels, conceivable and feasible.

Alternatively, the modules 21 to 24 However, each be the same design, so that all containers 3 with the same sort of labels, especially just the labels 4 be provided.

As a result, the label has 4 at the container 3 not just a function as advertising or data area. In addition, the label has 4 the function of contributing to the stability of the overall packaging for the product in the container 3 to perform, said grip function and the aforementioned sunscreen for the product. From the stability function also results in the effect that the stability of the container 3 without label 4 due to a reduced container wall thickness may be lower than in a conventional container 3 , Through the depressions 34 in the container 3 and the special folds 43A to 43D and 44A to 44D or folds of the label 4 This results in defined gripping surfaces that allow the user to handle the container 3 facilitate.

Due to the low use of adhesive 5 and special adhesive 5 is the label 4 easily from the container 3 separable and can therefore already at 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 device 20 has at least one of the modules 21 . 22 instead of the label supply unit (s) 211 . 221 which the labels 4 by means of label rolls and associated cutting unit, a magazine which holds the labels 4 provides. The magazine can be assigned two hot glue units, wherein one of the hot glue units the magazine in the transport direction TR the container 3 is upstream and the other of the hotmelt plants the magazine in the transport direction TR the container 3 is downstream.

7 and 8th illustrate a pressing unit 51 according to a second embodiment. The pressing unit 51 is as a clamping element of the transport device 50 provided, in particular in the outlet star.
