Description

Description

The invention relates to a blank, as well as a cuff-shaped outer part formed from a blank for encasing a cup-shaped inner container and a combination packaging container formed from an inner container and the outer part. However, the invention also relates to a method for producing the combination packaging container, as well as a method for separating the combination packaging container into its inner container and the outer part by separating the overlap area of the outer part.

[0002] WO 2020/245148 A1 by the same applicant describes a cuff-shaped outer part formed from a blank, the blank being wound into a jacket and the end sections of which are connected to one another in an overlap area. A target separation area includes an actuating means with a detection section for the separation of separation sections located on both sides. Seen in the circumferential direction, the detection section is arranged laterally spaced apart from it by an offset with respect to the separating sections which are aligned towards one another and an imaginary straight connecting line between them. A separate intended separation section is formed in the casing of the outer part between each detection section end and a respective end of the separating sections. The lower end face of the outer part facing the closed end of the inner container is supported on a support shoulder which projects radially outwards. This achieves, within certain limits, a positive mutual holding between the outer part and the inner container. In the event of tolerance-related manufacturing inaccuracies, a change in temperature and/or moisture absorption of the blank, which is preferably made from a cellulose material, the outer part can unintentionally detach from the inner container.

DE 29714534 U1 generally discloses a cup for holding liquid or pasty material with a detachable sleeve made of paper or cardboard and an adhesive connection.

[0004] US 2009214837 A1 describes labels for attachment to various articles, for example bottles, cups, containers, etc., and refers in particular to labels with insulating properties. The object of the present invention was to overcome the disadvantages of the prior art and to provide a cuff-shaped outer part and a combination packaging container comprising a cup-shaped inner container with a cuff-shaped outer part surrounding it, in which the cuff-shaped outer part can be easily removed from the inner container for recycling purposes .

According to the invention, a blank is provided for an outer part for encasing a cup-shaped inner container, the inner container having a container jacket which has an open end and an end closed with a base,

The adhesive layer is designed in such a way that the first end section and the second end section can be detached from one another in the overlap area from the coupled state.

The blank according to the invention has the surprising advantage that a detachable adhesive layer can be used to ensure that a combination packaging container wrapped with the blank can be separated in an improved manner.

In a first exemplary embodiment it can be provided that the blank is formed in one piece. Furthermore, it is also conceivable that the blank itself is formed from several parts, whereby the individual parts of the blank can also adhere to one another by means of an adhesive layer.

This has the advantage that the printing layer can be used to give the blank or subsequently a combination packaging container wrapped with the blank a desired design. The sealing layer can protect the printing layer or the carrier layer from environmental influences. The multi-layer composite structure can also achieve the surprising advantage that the first end section and the second end section in the overlap area can be solved particularly well in a blank applied to the combination packaging container, whereby the separability of the combination packaging container can be improved.

Furthermore, it is also conceivable that the sealing layer is partially excluded or interrupted in the area of the adhesive layer, so that the adhesive layer can connect directly to one of the layers lying under the sealing layer.

In particular, it can be provided that the sealing layer forms the outer surface of the blank or the outer part. This has the advantage that this measure protects the external part from environmental influences. In addition, this measure can surprisingly achieve particularly good separability of a combination packaging container wrapped with the blank.

[0013] Furthermore, it can be provided that the sealing layer is formed from a heat-resistant lacquer. The heat resistance can be up to a maximum temperature between 160°C to 300°C. In particular, it can be provided that a paint is selected which can be exposed to a temperature of 180 ° C to 200 ° C over a period of 15 minutes to 20 minutes without destroying the paint film. This has the advantage that this measure can create a sealing layer to which a hot-melt adhesive can be applied without the hot-melt adhesive melting the sealing layer. This can improve the solubility of the adhesive layer.

In particular, it can be provided that the adhesive layer can be removed from the sealing layer without leaving any residue and without being destroyed.

[0015] In particular, it can be provided that the paint is water-based. Furthermore, the varnish can be transferred to a varnish plate in a printing press via a chamber doctor system - a pressurized chamber - via an anilox roller. The varnish can have a specific grammage of 0.5g/cm* to 1.5g/cm?, especially 0.8g/cm? up to 1.2g/cm®, preferably 0.95g/cm? up to 1.05g/cm? be applied.

Furthermore, it can be provided that in the area of the first end section the printing layer is left out in the area of the adhesive layer, in particular that the sealing layer is arranged directly on the carrier layer in this area. This brings the

The surprising advantage is that this measure makes it easier for the adhesive layer to be detached from the first end section of the blank, whereby the separability of the combination packaging container can be improved.

[0017] In particular, it can be provided that the extent of the recess of the printing layer is smaller than the extent of the overlap area. It can thereby be achieved that the visible surface of the outer part of the combination packaging container can have an entire optical representation on its outer surface.

In particular, it can be provided that the pressure recess has a recess depth and the overlap has an overlap depth, the recess depth being smaller than the overlap depth.

The combination packaging container according to the invention has the surprising advantage that a removable adhesive layer can ensure that the inner container wrapped with the outer part can be separated from one another in an improved manner in the event of disposal. In particular, the measures according to the invention can be used to achieve an automated separation of the outer part from the inner container if the combination packaging container is excessively deformed when empty, as is the case, for example, when transporting garbage. This results in a complete separation of the outer part from the inner container. This means that the recyclability of the combination packaging container can be achieved even if the end user does not consciously separate the outer part from the inner container in order to dispose of them separately. The construction of the combination packaging container according to the invention can ensure that when the combination packaging container is filled, undesirable detachment of the outer part from the inner container is prevented and the separability is improved in the event of disposal.

[0026] According to a further development, it is possible for the adhesive to be a hot melt adhesive. This has the advantage that a hot melt adhesive can be easily applied to the blank or to the outer part during the manufacturing process and also has surprisingly good solubility.

In an alternative embodiment variant, it is conceivable that the adhesive is a pressure-sensitive adhesive.

[0028] Furthermore, it can be expedient if the adhesive layer in the first end section rests on an outer surface and the adhesive layer in the second end section rests on an inner surface, the first end section having a first tensile strength in the area of the outer surface on which the adhesive layer rests and the second end section in the area of the inner surface on which the adhesive layer rests has a second tensile strength and that the adhesive has a peel strength,

wherein the peel strength of the adhesive is less than the first tensile strength of the outer surface of the first end section. Furthermore, it can be provided that the peel strength of the adhesive is greater than the second tensile strength of the inner surface of the second end section. This has the surprising advantage that this measure can improve the ability to separate the two end sections. In particular, this measure allows the adhesive layer to be completely removed from the outer surface of the first end section during separation.

[0029] Furthermore, it can be provided that the first end section has a first tensile strength in the region of a first surface on which the adhesive layer rests and that the second end section has a second tensile strength in the region of a second surface on which the adhesive layer rests and that the adhesive has peel strength,

wherein the peel strength of the adhesive is lower than the first tensile strength of the first surface and/or

wherein the peel strength of the adhesive is less than the second tensile strength of the second surface. This has the surprising advantage that this measure can improve the ability to separate the two end sections.

[0030] In addition, it can be provided that the adhesive has a peel strength and a shear strength, the adhesive being selected such that the shear strength is greater than the peel strength. This has the surprising advantage that this measure can prevent undesirable separation of the two end sections and at the same time a desired separation of the two end sections can be achieved in the event of disposal.

[0031] Furthermore, it can be provided that the adhesive, when adhered to the sealing layer, has a shear strength of between 0.04 N/mm? and 2 N/mm®?, especially between 0.09 N/mm? and 1 N/mm®?, preferably between 0.12 N/mm? and 0.5 N/mm? having. This has the surprising advantage that this measure can prevent undesirable separation of the two end sections and at the same time a desired separation of the two end sections can be achieved in the event of disposal.

[0032] According to a special embodiment, it is possible for the adhesive to have a peel strength of between 0.0005 N/mm? and 1 N/mm®?, especially between 0.001 N/mm? and 0.01 N/mm®, preferably between 0.003 N/mm? and 0.007 N/mm? having. This has the surprising advantage that this measure can prevent undesirable separation of the two end sections and at the same time a desired separation of the two end sections can be achieved in the event of disposal.

[0033] According to an advantageous development, it can be provided that the adhesive has a tensile strength between 0.1 N/mm? and 60 N/mm?, especially between 1 N/mm? and 30 N/mm®, preferably between 10 N/mm? and 20 N/mm? having. This has the surprising advantage that this measure can prevent undesirable separation of the two end sections and at the same time a desired separation of the two end sections can be achieved in the event of disposal.

The strength values can be determined using the standard “DIN EN 1465 Adhesives - Determination of the tensile shear strength of high-strength overlap bonds”, whereby the material pairing present on the product is used as the material pairing to determine the strength values.

In particular, it can be advantageous if the adhesive has a peel strength, a shear strength and a tensile strength, the adhesive being selected such that the tensile strength is greater than the shear strength and the tensile strength is greater than the peel strength. This has the surprising advantage that this measure can prevent undesirable separation of the two end sections in a filled combination packaging container and at the same time a desired separation of the two end sections can be achieved in the event of disposal.

[0036] Furthermore, it can be provided that a first longitudinal edge is formed on the first end section, which has a first longitudinal edge length, wherein the adhesive layer has an elongated extension and is arranged running parallel to the longitudinal edge. This has the advantage that the outer part can be glued evenly over its entire height and thus has a homogeneous shape. As a result, an improved hold of the outer part on the inner container in the intended state can be achieved in a surprising manner and, in addition, improved separability of the outer part from the inner container can be achieved in the event of disposal.

[0037] In addition, it can be provided that a length of the adhesive layer is between 100% and 80%, in particular between 99% and 85%, preferably between 97% and 93% of the first longitudinal edge length. This has the advantage that the outer part can be closed evenly over its entire height and thus has a homogeneous shape. As a result, an improved hold of the outer part on the inner container in the intended state can be achieved in a surprising manner and, in addition, improved separability of the outer part from the inner container can be achieved in the event of disposal. In particular, it can be provided that the adhesive layer is strip-shaped. In an alternative embodiment variant, it can also be provided that the adhesive layer is applied at intervals running parallel to the longitudinal edge, for example in the form of adhesive layer points between the first end section and the second end section.

[0038] Also advantageous is an embodiment according to which it can be provided that a width of the adhesive layer is between 1mm and 10mm, in particular between 1.5mm and 7mm,

is preferably between 2.5mm and 3.5mm. This has the advantage that the outer part can be closed evenly over its entire height and thus has a homogeneous shape. As a result, an improved hold of the outer part on the inner container in the intended state can be achieved in a surprising manner and, in addition, improved separability of the outer part from the inner container can be achieved in the event of disposal. In particular, it can be provided that the adhesive layer is strip-shaped. In an alternative embodiment variant, it can also be provided that the adhesive layer is applied at intervals running parallel to the longitudinal edge, for example in the form of adhesive layer points between the first end section and the second end section.

According to a further development, it is possible for the adhesive layer to be arranged at a distance between 1mm and 10mm, in particular between 1.5mm and 7mm, preferably between 2.5mm and 3.5mm from the second longitudinal edge. This has the advantage that the outer part can be closed evenly over its entire height and does not have any loose, protruding areas, which would lead to an undesirable separation of the outer part when handling with the combination packaging container. As a result, an improved hold of the outer part on the inner container in the intended state can be achieved in a surprising manner and, in addition, improved separability of the outer part from the inner container can be achieved in the event of disposal.

[0040] In particular, it can be provided that the adhesive layer is strip-shaped. In an alternative embodiment variant, it can also be provided that the adhesive layer is applied at intervals running parallel to the longitudinal edge, for example in the form of adhesive layer points between the first end section and the second end section.

[0041] Furthermore, it can be expedient if at least one predetermined separation area is formed in the blank of the outer part, the predetermined separation area being formed in the form of a perforation in the blank of the outer part, the predetermined separation area being arranged at a distance from the adhesive layer. This has the advantage that the outer part can optionally be separated from the inner container by cutting it in the target separation area. According to studies carried out, the presence of the perforation encourages the end user to actively separate the outer part of the combination packaging container from the inner container and dispose of it separately.

[0042] In addition, it can be provided that the inner container has a shoulder projecting radially outwards in the area of the closed end, the shoulder serving as an axial stop for the first end face of the outer part. This has the advantage that this measure can prevent the outer part from slipping off the inner container in the axial direction.

This means that unwanted separation of the outer part from the inner container before disposal can be prevented.

[0043] Furthermore, it can be provided that the shoulder is designed to taper conically at least in sections from the open end to the closed end. This measure allows the axial pushability of the outer part onto the inner container to be improved when producing the combination packaging container.

According to a special embodiment, it is possible for the container jacket of the inner container to be designed to taper conically at least in sections from the open end to the closed end. This has the advantage that these measures can improve the stackability of several of the combination packaging containers.

[0045] Method for producing a combination packaging container, comprising the method

racing steps:

- providing a cup-shaped inner container, the inner container having a container jacket which has an open end and an end closed with a base

having;

- forming an outer part, for encasing the inner container, the outer part being formed from a blank, which blank has a first end section and a second end section, the blank being wound into a jacket and the first end section and the second end section in an overlap area are coupled to one another by means of an adhesive layer made of an adhesive, the outer part further having a first end face and a second end face and the two end faces being spaced apart from one another,

- axially pushing the outer part onto the inner container, with the first end face facing the bottom and the second end face facing the open end of the inner container, or forming the outer part directly by wrapping the inner container. The adhesive layer is designed in such a way that the first end section and the second end section can be separated from one another in the overlap area.

[0046] Furthermore, it is provided that the blank has a multi-layer composite structure, with a carrier layer being formed from a cellulose material and with a printing layer being arranged on the carrier layer at least in sections and with a sealing layer being formed at least in sections, with the printing layer being formed at least in sections is arranged between the carrier layer and the sealing layer, wherein the adhesive layer is arranged on the sealing layer.

[0047] In a first embodiment variant, it can be provided that the shaping of the outer part and the bonding of the first end section and the second end section in an overlap area by means of an adhesive layer takes place in a separate process step, and the outer part thus shaped is only carried out in a further process step by axial displacement is pushed onto the inner container.

In an alternative embodiment, it is also conceivable that the outer part is wound or formed directly onto the inner container. It can be provided that the inner container is attached to a winding mandrel.

The method according to the invention has the surprising advantage that a removable adhesive layer can ensure that the inner container wrapped with the outer part can be separated from one another in an improved manner in the event of disposal. In particular, the measures according to the invention can be used to achieve an automated separation of the outer part from the inner container if the combination packaging container is excessively deformed when empty, as is the case, for example, when transporting garbage. This results in a complete separation of the outer part from the inner container. This means that the recyclability of the combination packaging container can be achieved even if the end user does not consciously separate the outer part from the inner container in order to dispose of them separately. The construction of the combination packaging container according to the invention can ensure that when the combination packaging container is filled, undesirable detachment of the outer part from the inner container is prevented and the separability is improved in the event of disposal.

In particular, it can be advantageous if a hot melt adhesive is used to apply the adhesive layer to the blank, which is applied to an outer surface of the blank in the area of the first end section before the outer part is formed. Such a hot melt adhesive can be applied to the blank in a simpler manner and can also result in improved separability.

[0051] In an alternative embodiment variant, it can also be provided that the adhesive layer is applied to the blank before the outer part is formed in the region of the second end section on an inner surface of the blank.

[0052] Furthermore, it can be provided that the hot melt adhesive is originally in granular form and is melted by heating, in particular to a temperature between 130 ° C and 160 ° C, and for application to the outer surface of the blank through a nozzle

is pressed. This has the advantage that this measure can achieve a sufficient connection of the hot melt adhesive with the blank.

According to the invention, a method is provided for separating a combination packaging container with a cup-shaped inner container, the inner container having a container jacket which has an open end and an end closed with a base and an outer part which encases the inner container, the outer part is formed from a blank, which blank has a first end section and a second end section, the blank being wound into a jacket and the first end section and the second end section being coupled to one another in an overlap area by means of an adhesive layer made of an adhesive, the outer part further has a first end face and a second end face and the two end faces are spaced apart from one another, with the first end face facing the floor and the second end face facing the open end of the inner container. To separate the outer part from the inner container, the first end section of the outer part and the second end section of the outer part are separated from one another in the overlap area on the adhesive layer.

This has the advantage that the recyclability of the combination packaging container can be achieved even if the end user does not consciously separate the outer part from the inner container in order to dispose of them separately.

In particular, it can be provided that the method of separating the combination packaging container is carried out with an empty combination packaging container.

[0056] Also advantageous is an embodiment according to which it can be provided that when the first end section of the outer part and the second end section of the outer part are released from one another,

the adhesive layer is removed from the first end section without damaging the first end section and the adhesive layer remains at the second end section, or

the adhesive layer is removed from the second end section without damaging the second end section and the adhesive layer remains at the first end section. This results in improved separability of the outer part from the inner container.

[0057] According to a further development, it is possible that in order to separate the outer part from the inner container, the first end section of the outer part and the second end section of the outer part in the overlap area on the adhesive layer are separated from each other by a pressure force directed in the direction of the combination packaging container (-F-) is applied and the outer part and the container jacket of the combination packaging container are spatially deformed, with the spatial deformation of the outer part and the container jacket in the area of the adhesive layer introducing a separation force which is used to release the adhesive layer from the first end section or to Dissolving the adhesive layer from the second end section leads. It can thus be achieved that the separation of the combination packaging container is achieved, for example, by the environmental conditions during the removal of the waste. Particularly when transported in a garbage truck, large forces and thus large deformations act on the combination packaging container, which can result in the outer part being separated from the inner container.

[0058] Furthermore, it may be expedient if the spatial deformation of the outer part includes an axial deformation that is greater than 1.5 cm from an undeformed state of use and/or includes a radial deformation that is greater than 2 cm from an undeformed state of use . It can thus be achieved that the separation of the combination packaging container is achieved, for example, by the environmental conditions during the removal of the waste. Particularly when transported in a garbage truck, large forces and thus large deformations act on the combination packaging container, which can result in the outer part being separated from the inner container.

[0059] Furthermore, a sleeve-shaped outer part can be provided, which serves to encase a cup-shaped inner container to form a combination packaging container,

- wherein the inner container has a container jacket which is designed to taper conically from an open end towards an end closed with a base,

- wherein the outer part is formed from a blank, which blank is wound into a jacket in its erected state and a first end section and a second end section of the jacket facing this are connected to one another in an overlap area,

- wherein the outer part further has a first end face and a second end face and the two end faces are spaced apart from one another and, in the erected state, define an overall height of the jacket with a longitudinal axis extending in the direction of the overall height, the first end face defining a support area at least in sections and further the first end face faces the floor and the second end face faces the open end of the inner container, and

- whereby an additional support device is also provided, which additional support device is arranged or designed in the area of the first end face of the outer part formed from the blank, and

- The additional support device defines a clear inner dimension which is smaller than an inner dimension of the outer part in its undeformed design in the area of the first end face.

The advantage achieved in this way is that the support area or support section on the shoulder of the inner container, which is already defined by the first end face, is further improved by providing or designing the additional support device. In the undeformed design of the bottom end region of the blank or the outer part formed from it, the additional support device reduces the clear inner dimension with respect to the undeformed design and thus achieves an even better locking effect on the inner container. Tolerance-related manufacturing inaccuracies do not lead to any further disadvantages in the stationary positioning of the outer part on the inner container and this even without the adhesive point between the container jacket and the outer part, which is otherwise usually attached for security purposes. This creates an outer part that can also be more easily removed from the inner container for disposal.

[0061] In an advantageous embodiment, it can be provided that the additional support device comprises at least one support element and the at least one support element defines the clear inner dimension. The at least one support element forms the additional support device and projects, starting from the undeformed bottom edge region or edge section of the outer part, in the direction of the longitudinal axis and forms the reduction in the clear internal dimension.

[0062] Furthermore, it can be advantageous if the at least one support element is formed into the material of the blank starting from an outer surface of the outer part in the direction of an inner surface and projects in the radial direction over the undeformed inner surface in the direction of the longitudinal axis. This means that the material can be used directly to form the at least one support element and can thus be dispensed with additional components or component components. This means that no additional material is used that would otherwise have to be treated separately during separation and disposal.

Another embodiment is characterized in that the at least one support element has a longitudinal extension starting from the first end face towards the second end face. In this way, a defined projection of the at least one support element over the inner surface of the blank or outer part can be realized, which forms the enlargement or widening of the bottom support area.

A further possible embodiment has the features that a plurality of support elements are provided and the support elements are arranged at a distance from one another along the first end face in the circumferential direction. This means an even better supporting effect can be achieved over the entire circumference, even under changing environmental conditions and/or during handling

be achieved.

[0065] A further embodiment provides that the additional support device comprises at least one forming section, which at least one forming section is formed into the material of the blank starting from an inner surface of the outer part in the direction of an outer surface and the at least one forming section is spaced from the first end face is arranged. As a result, an opposite orientation of the edge section can be formed.

Another embodiment is characterized in that the at least one forming section, viewed in axial section, has a preferably curved longitudinal profile and an end section adjoining the forming section in the direction of the first end face is aligned in an inclined manner in the direction of the longitudinal axis. In this way, additional stiffening of the bottom end section or surrounding edge area can be achieved.

A further preferred embodiment is characterized in that the at least one forming section has a parallel longitudinal course with respect to the first end face. In this way, a uniform design of the additional support device projecting towards the inner container can be achieved.

[0068] Furthermore, it can be advantageous if the forming section is arranged to run continuously in the circumferential direction along the first end face. This means that a secure and uniform support effect can be achieved over the entire circumference, especially for inner containers with a round cross-sectional shape.

Another alternative embodiment is characterized in that a plurality of forming sections are provided and the forming sections are arranged at a distance from one another along the first end face in the circumferential direction. This variant can be used in particular for inner containers which, when viewed in cross section, have container walls that run in a straight line and each have a rounded corner area in the transition areas in between. This can prevent unwanted wrinkle formation in the U-transition areas.

[0070] A further embodiment provides that an adhesive is provided in the overlap area between the two end sections, which adhesive has a first adhesive force value when viewed in the circumferential direction and has a second adhesive force value in the radial direction, the first adhesive force value being greater than the second adhesive force value. Due to the mutually different adhesive force values of the adhesive holding the blank together at its mutually facing end sections, on the one hand the cohesion can be made higher when viewed in the circumferential direction and, on the other hand, if the force is introduced differently, a lighter separating effect with a reduced adhesive force can be made possible. This facilitates the separation process of the overlap area when separating the outer part from the inner container. If a pressure force is exerted in the direction of the inner container, this can simply lead to a mutual detachment of the two end sections connected to one another. This means that a simple process of separating the outer part from the inner container can also be carried out during disposal.

Another embodiment is characterized in that at least one predetermined separation region is formed or provided in the jacket of the outer part. By providing a separate desired separation area in the jacket of the outer part, a further possibility of detaching the outer part from the inner container can also be created. This means that the user or consumer of the combination packaging container can carry out a directed separation after consuming the contents and thus carry out the proper separation of materials in a known manner.

[0072] A further embodiment provides that the cuff-shaped outer part is supported in the axial direction by means of its additional support device on the shoulder of the inner container, excluding any additional adhesive. This means that after use the combination packaging container can be put into the inner container even more easily and, above all, more safely

External part must be separated. Even after the outer part has been separated, the outer part forms a coherent piece which can be easily and, above all, in one piece and disposed of properly and collected for recyclables. By eliminating the additional adhesive, savings and possible contamination on the machine when applying the adhesive can be avoided.

[0073] In a further alternative variant, it can be provided that a section of the outer part is glued to the inner container and that this section remains on the inner container after the outer part has been separated from the inner container, this section being coupled to the remaining parts of the outer part by means of an adhesive layer . In particular, it can be provided that this section has only a small extent, so that there is only minimal contamination of the plastic waste. This measure allows improved durability of the entire outer part of the inner container to be achieved in order to prevent unwanted detachment. In particular, it can be provided that the section remaining on the inner container is dimensioned such that the mass of the section remaining on the inner container is less than 5% of the mass of the inner container.

For a better understanding of the invention, it will be explained in more detail using the following figures.

[0091] As used herein, the terms “comprising,” “comprising,” “comprising,” “includes,” “including,” “contains,” “containing,” and any variations thereof are intended to cover non-exclusive inclusion.

[0092] “Optional” can also be used as a further term. This means that this process step or this system component is basically present, but can be used depending on the operating conditions, but this does not necessarily have to be done.

1 to 4 show an exemplary embodiment of a combination packaging container 1 as an example of a variety of possible different shapes, the combination packaging containers 1 being cup-shaped or bowl-shaped. The combination packaging container 1 comprises a cup-shaped or bowl-shaped inner container 2 with a base 3 and a container jacket 4. The inner container 2 also has an open end 5 on its side facing away from the base 3, with a in the area of its open end 5 Container jacket 4 outwardly projecting flange 6 can be provided. The bottom 3 forms a closed end 7 for the container jacket 4.

The inner container 2 is preferably formed by a component produced in a deep-drawing process, which can be produced quickly and, above all, in a short cycle time. The process of deep drawing is well known and will therefore not be discussed in more detail. The deep-drawing process is particularly suitable for producing the inner container 2 with a sufficient wall thickness from a layer to be formed made of a formable material using a deep-drawing tool, which ensures tightness during storage, use and even disposal. This manufacturing process allows relatively thin wall thicknesses of the inner container 2 to be manufactured. The inner container 2 can also be formed using other manufacturing processes, such as an injection molding process.

Due to the cup or bowl-shaped design of the inner container 2, a longitudinal axis 8 extends in the axial direction between the open end 5 and the end 7 closed with the base 3, which can also represent a central axis if it is symmetrical. In the area of the flange 6 it is possible to arrange or connect a sealing plate (not shown in detail) with it. In this case, the flange 6 forms a sealing flange.

[0096] In the axial direction and thus in the direction of the longitudinal axis 8, the inner container 2 has a container height 9 between its open end 5, in particular the flange 6, and the base 3, whereby the holding volume of the inner container 2 is determined depending on the cross-sectional dimensions. A receiving space for the inner container 2 is thus defined by the container height 9 in conjunction with the cross-sectional dimensions.

The container jacket 4 is understood to be that section of the inner container 2 which is located predominantly between the open end 5, in particular the flange 6, and the base 3

axial direction extends. The inner container 2 is preferably designed with its container jacket 4 in such a way that it preferably tapers conically starting from the open end 5 towards the bottom 3.

[0098] Furthermore, the container jacket 4 of the inner container 2 can have a backing 10 in its peripheral section adjacent to the base 3. The backing 10 is also part of the container jacket 4, but when viewed in axial section it is arranged offset inwards relative to an imaginary, straight connecting line between the flange 6 and the base 3. The backing 10 in turn has at least two backing wall sections, which are not specified in more detail, the two backing wall sections, seen in axial section, having a different inclination or direction with respect to the longitudinal axis 8 than the rest of the container jacket 4. The backing 10, compared to the in Seen in axial section, the straight-line arrangement of the container jacket 4 between the flange 6 and the base 3 is arranged inwards and thus offset in the direction of the receiving space.

[0099] Seen in axial section, the first rear wall section immediately adjoining the base 3 is arranged or designed to extend predominantly in the direction of the container height 9 towards the open end 5. The further rear wall section extends in a predominantly vertical direction with respect to the container height 9, starting from the end of the first rear wall section facing away from the bottom 3 towards the container jacket 4. In the present exemplary embodiment, the further rear wall section forms a stacking shoulder. This stacking shoulder serves to enable a similar combination packaging container 1 with its base 3, in particular the edge-side transition section between the base 3 and the container jacket 4, to be supported on it.

[00100] Furthermore, the inner container 2 can have a shoulder 11 or a bead projecting onto the side facing away from the longitudinal axis 8 in the immediate transition area between the bottom 3 and the container jacket 4, in particular between the bottom 3 and the backing 10. The shoulder 11 or the bead can be designed to be circumferential. Furthermore, it is also conceivable that the shoulder 11 or the bead are formed in sections.

The combination packaging container 1 further comprises an outer part 12, which is sleeve-shaped or jacket-shaped and surrounds the inner container 2 in the area of its container jacket 4 at least in sections or areas.

The previously described shoulder 11 can, for example, serve to axially fix the cuff-shaped outer part 12 on the inner container 2. In this case, the cuff-shaped outer part 12 is supported with its first end face 19 facing the bottom 3 of the inner container 2 on this shoulder 11 formed in the transition region. The shoulder 11 can therefore also be referred to as a locking means for holding the outer part 12 on the inner container 2. The front side 19 forms a front edge in its longitudinal extent, which in the joined position defines a support area at least in sections and is supported against the shoulder. For simplified axial joining of the outer part 12 to the inner container 2, it can be provided that the shoulder 11 is designed to taper conically at least in sections from the open end 5 to the closed end 7.

[00103] Furthermore, the cuff-shaped outer part 12 comprises a second end face 20, which in turn faces the open end 5 or the flange 6.

The cuff-shaped outer part 12 is preferably formed from a cellulose material, such as a cardboard material, with sufficient strength with regard to the absorption and transmission of, in particular, axially acting compressive forces and is wound from a flat blank 13 to form a jacket, as has already been done is well known. The blank 13 is usually printed in its undeformed flat position and, if necessary, provided with an additional coating. In particular, it is of course also conceivable that the blank 13 is designed in several parts. A cellulose material is usually used as the material for the blank 13, although this can also be cardboard or strong paper produced using a recycling process. If a layer or layer of the outer part 12 is made of one

Recycled material is formed, an additional layer of higher quality paper can be arranged on or connected to at least one of the surfaces. This additional layer is used for flawless printing to produce decorations, labels and product information.

The sleeve-like or jacket-like outer part 12 leads to an additional reinforcing or stiffening effect of the inner container 2 and thus of the entire combination packaging container 1.

This ensures, on the one hand, high strength and good thermal insulation and, on the other hand, optimal light protection for the contents of the packaging container.

In particular, it can also be provided that the cardboard is additionally coated or sealed with a water-repellent material in the area of the cut edges. This is particularly advantageous when the combination packaging containers 1 are exposed to increased moisture. Coating the cardboard used for the outer part 12 with a water-repellent layer prevents the cardboard from swelling in a humid environment and ultimately from detaching from the container jacket 4 of the combination packaging container 1.

The cuff-shaped outer part 12 is wound from the mostly flat blank 13 to form a jacket. Furthermore, it can be provided that the adhesive layer 48 is applied to an outer surface 42 of the blank 13 in the area of the first end section 14. The adhesive can be in the form of granules and melted. In the melted state, the adhesive can then be sprayed onto the outer surface 42 of the end section 14 using a nozzle. By winding the blank, mutually facing end sections 14, 15 are then connected to one another in an overlap area 16, shown in simplified form. This is done by a so-called overlap seam, by means of which the first end section 14 and the second end section 15 adhere to one another, for example by means of an adhesive layer 48. The first end section 14 of the blank 13 ends with a first longitudinal edge 17 and the second end section 15 in turn ends with a second longitudinal edge 18. In the overlap area 16, the two longitudinal edges 17, 18 run approximately parallel to one another, with the overlap area 16 in between when viewed in the circumferential direction an overlap width is formed. In particular, it can be provided that in the wound state of the outer part 12, the second end section 15 is folded over the first end section 14 on the outside.

[00109] The sleeve-shaped outer part 12 can be wound with the aid of a winding mandrel.

The outer part 12 further has the first end face 19 and the second end face 20, the two end faces 19, 20 being spaced apart from one another and defining a height 21 of the jacket in the erected state. The previously described longitudinal axis 8 can also define the common longitudinal axis for the outer part 12, in particular when the outer part 12 is in its mounted position on the inner container 2. In most cases, the overall height 21 of the jacket is slightly lower than the container height 9 of the inner container 2 in the same spatial direction - namely in the direction of the longitudinal axis 8.

A possible, but not mandatory, arrangement and/or design for separating the outer part 12 from the inner container 2 is described below. This is a so-called target separation area 22, which is arranged and formed in the material of the outer part 12. The following detailed description of the desired separation area 22 corresponds to the design as already described in WO 2020/245148 A1. However, the desired separation area 22 could also be designed differently and deviating from this.

In order to enable a defined separation and associated subsequent separate disposal of the inner container 2 and outer part 12 for a consumer, at least one predetermined separation area 22 formed in the jacket of the outer part 12 is provided. The

Target separation area 22 here comprises a first separation section 23, a second separation section 24 and an actuating means 25 for starting and beginning the cutting process of the target separation area 22 along the two separation sections 23, 24. The actuation means 25 is seen in the direction of the overall height 21 of the jacket between the two End faces 19, 20 arranged. It is advantageous if the actuating means 25 is arranged approximately centrally between the two end faces 19, 20 which are spaced apart in the direction of the overall height 21, this essentially corresponding to half the overall height 21. For the actuating means 25, the indication “centre” refers to half the dimension in the direction of the overall height 21 or the longitudinal axis 8. The two separating sections 23, 24 are provided on both sides of the actuating means 25 and each extend in the direction of the respective end face 19, 20. Seen in the direction of the overall height 21 of the jacket, the two separating sections 23, 24 of the desired separation area 22 are each aligned towards one another from the two end faces 19, 20 and thus define an imaginary, straight connecting line 26 between them, which is shown in dashed lines. The converging alignment of the two separating sections 23, 24 is in the direction of the actuating means 25. The two separating sections 23, 24 can either be aligned with one another as seen in the direction of the overall height 21 of the jacket or can also run slightly inclined with respect to the first longitudinal edge 17 in the direction of the actuating means 25 located between them. Due to this slight inclination, the separation process can be further improved after the two separation sections 23, 24 have been separated towards the two end faces 19, 20. Furthermore, it is also conceivable that the two separating sections 23, 24 of the desired separating area 22 are designed in an arc shape. For example, the two separating sections 23, 24 of the desired separating area 22 can run in a spiral shape.

Depending on the design of the intended separation points, which will be described in more detail later, the imaginary connecting line 26 is assumed to run in a middle of the intended separation points. The actuating means 25 in turn defines a detection section 27 with a first detection section end 28 spaced apart from one another in the direction of the overall height 21 and a second detection section end 29. The two detection section ends 28, 29 are thus seen in the direction of the overall height 21 of the jacket arranged at a distance of 30 from each other or end there. It can also be seen that the detection section 27 of the actuating means 25 is arranged or formed outside the overlap area 16.

[00114] An arrangement of the actuating means 25 is provided here, in which the detection section 27, viewed in the circumferential direction, is arranged at a distance laterally from it by an offset 31 with respect to the separating sections 23, 24 of the desired separation region 22 which are aligned towards one another and the straight connecting line 26 imaginary between them is trained. The offset 31 can have a value which is selected from a range of values with a lower limit of 1.0mm and an upper limit of 10.0mm. The range of values can preferably have a lower limit of 2.0mm and an upper limit of 6.0mm.

The first separating section 23 can in turn have a first end 32 facing the actuating means 25, wherein the second separating section 24 can have a second end 33 facing the actuating means 25. In the area of the imaginary connecting line 26 between the two ends 32, 33, the jacket can be designed to be uninterrupted due to the intended lateral offset 31 of the actuating means 25. The arrangement of the two ends 32, 33 of the separating sections 23, 24, which are spaced apart in the direction of the overall height 21, with respect to the detection section 27 forming the actuating means 25 can be selected such that the first detection section end 28 of the detection section 27 is the adjacent first end 32 of the first separating section 23 extends to the side facing away from the second separating section 24. Due to the lateral offset 31 of the detection section 27 to the side facing away from the overlap area 16, a first predetermined separation section 34, viewed in the circumferential direction, is formed in the jacket of the outer part 12 between the first detection section end 28 and the first end 32 of the first separation section 23.

[00116] Furthermore, it can be provided that the second detection section end 29 of the detection section 27 extends over the adjacent second end 33 of the second separating section 24 on the side facing away from the first separating section 23. This means that, analogous to the first predetermined separation section 34, a second predetermined separation section 35 is also formed in the casing of the outer part 12 between the second detection section end 29 and the second end 33 of the second separation section 24, viewed in the circumferential direction. The two desired separation sections 34, 35 are formed by the reduced dimension of the jacket material between the respective detection section end 28 or 29 and the respective end 32 or 33. The two ends 32 and 33 of the separating sections 23, 24 are arranged closer to one another than the two detection section ends 28 and 29, which are spaced apart by the distance 30.

This makes it possible for a user of the combination packaging container 1 to detect the actuating means 25 with its detection section 27, then the two desired separation sections 34 35 starting from the detection section 27 up to the respective ends 32, 33 of the two separation sections 23, 24 and then to separate the two separating sections 23, 24 until the jacket is completely severed. This means that the outer part 12 can simply be separated from the inner container 2 and disposed of according to type. The two desired separation sections 34, 35 each form starting sections for the separation of the two separation sections 23, 24.

Each of the two separating sections 23, 24 can comprise a plurality of intended separating points arranged one behind the other in a row, which are usually designed as perforations, in particular also as short cuts, in the material of the outer part 12.

In this exemplary embodiment it is shown that the shape and position of the desired separation points can be chosen differently from one another. Therefore, those predetermined separation points which are arranged immediately adjacent to the respective detection section ends 28, 29 are referred to as first predetermined separation points 36. The further predetermined separation points provided in the following direction towards one of the two end faces 19, 20 are referred to as second predetermined separation points 37 and third predetermined separation points 38.

The predetermined separation points 36, 37, 38 are designed and arranged in mirror images of one another with respect to a plane 39 aligned centrally and in a normal orientation to the longitudinal axis 8 - see FIG. 1. Therefore, only those intended separation points 36, 37, 38 located in the area of the first separation section 23 are described in more detail and are to be transferred to the second separation section 24 in an analogous manner.

Furthermore, in the lower left corner area of the combination packaging container 1 shown in section in FIG. 1 and in the enlarged view in FIG of the outer part 12 formed therefrom, an additional support device 40 is provided or formed by solely forming the material of the blank 13. The additional support device 40 serves or is designed to ensure that the outer part 12 is or is supported even more securely on its shoulder 11 in the axial direction until it is detached from the inner container 2. The additional support device 40 is further designed such that a clear inner dimension of the fully formed outer part 12 is made smaller with respect to the undeformed design. The bottom end face 19 of the outer part 12 already forms or defines the support area that interacts with the shoulder 11, which is further improved, in particular enlarged, and made safer by the provision or design of the additional support device 40.

In this first exemplary embodiment shown here, the additional support device 40 comprises at least one support element 41, but preferably several support elements 41 arranged at a distance from one another along the first end face 19, which are arranged distributed over the circumference of the sleeve-shaped outer part 12. The individual support elements 41 can be formed into the material of the blank 13 by forming or embossing and are therefore each an integral part of the blank 13. The support elements 41 are starting from an outer surface 42 of the outer part 12 in the direction of an inner surface

43 molded and thus formed. These therefore protrude in the radial direction over the undeformed inner surface 43 in the direction of the longitudinal axis 8. The supernatant can have a value that comes from a value range whose lower limit is 0.05 mm, in particular 0.1 mm, and whose upper limit is 0.5 mm, in particular 0.2 mm.

A clear inner dimension 44 of the additional support device 40 formed by the support elements 41 can therefore be smaller than an inner dimension 45 of the outer part 12 in its undeformed configuration without the support elements 41. By molding in the at least one support element 41, the first one also becomes End face 19 is formed along its longitudinal course and thus also forms a support surface for the outer part 12 on the shoulder 11. The longitudinal course can also be designed in the form of a longitudinal corrugation.

The support element 41 has or the support elements 41 have a longitudinal extension starting from the first end face 19 towards the second end face 20. So the support element 41 extends or the support elements 41 reach up to the first end face 19. The length of the at least one support element 41 can be, for example, a few millimeters and depends on the size and design of the backing 10. 2 mm to 15 mm, preferably 5 mm to 10 mm, can be cited as possible examples. The cross-sectional shape of the support element 41 or the support elements 41 is only shown as an example. Instead of the more angular cross-sectional shape here, a rounded or arcuate cross-sectional shape would also be conceivable.

4 shows the blank 13 for forming the outer part 12 previously described in FIGS up to 3 can be used. In order to avoid unnecessary repetition, reference is made to the detailed description in the previous FIGS. 1 to 3.

The previously described desired separation area 22 is not shown in more detail here, but can also be provided as has already been described previously as a possible and optional variant. Furthermore, the orientation of the individual support elements 41 can be seen better here, starting from the first end face 19 facing the ground towards the second end face 20. Due to the arcuately curved longitudinal course of the two end faces 19, 20 and their common center (center of the radius), the individual support elements 41 also have a longitudinal course aligned with the center.

4, it can be provided that the adhesive layer 48 is applied to the outer surface 42 of the blank 13 in the area of the first end section 14. The adhesive layer 48 can be applied shortly before the blank 13 is formed into the outer part 12.

As can also be seen from FIG. 4, it can be provided that the adhesive layer 48 is designed in the form of a strip. The adhesive layer 48 can run parallel to the first longitudinal edge 17. Furthermore, it is conceivable that the adhesive layer 48 has a length 53 or a width 54. Furthermore, the blank 13 can have a longitudinal edge length 52 in the area of the first end section 14, in particular on the first longitudinal edge 17. When considering the longitudinal edge length 52, any shortening of the actual longitudinal edge length due to rounding or due to a phase is ignored here. The entire extent of the blank 13 between the first end face 19 and the second end face 20 is therefore considered as the longitudinal edge length 52.

4, it can be provided that the adhesive layer 48 is arranged in the wound state at a distance 55 from the second longitudinal edge 18. The position of the second longitudinal edge 18 in the wound state is indicated schematically by the dashed line in the illustration according to FIG.

5 and 6 show a further and possibly independent embodiment of the outer part 12 formed from the blank 13 to form a jacket, with the same reference numbers or component names being used for the same parts as in the previous FIGS. 1 to 4 be used. In order to avoid unnecessary repetitions, the

detailed description in the previous Fig. 1 to 4 pointed out or referred to.

[00131] It should be mentioned that here too it is optionally possible to provide or design the desired separation region 22, which has already been described in detail. For the sake of clarity and to avoid unnecessary repetition, the presentation and description of the same has been omitted.

The blank 13 and the outer part 12 formed therefrom in turn comprise the additional support device 40, which, however, has a different design than the previously described exemplary embodiment. To form the same, the additional support device 40 comprises at least one forming section 46, which is also formed into the material of the blank 13. In contrast to the exemplary embodiment described above, the at least one forming section 46 is formed starting from the inner surface 43 of the outer part 12 in the direction of its outer surface 42. Furthermore, the at least one forming section 46 is arranged at a distance from the first end face 19 in the direction of the opposite second end face 20.

Seen in axial section, the at least one forming section 46 can have a longitudinal course that is mostly curved outwards. Following the at least one forming section 46, an end section 47 located thereon is provided in the direction of the first end face 19. A corresponding end section 47 is therefore also formed or arranged adjacent to each forming section 46. The end section 47 can in turn be aligned in an inclined manner in the direction of the longitudinal axis 8.

As can now be seen better from FIG. 5, the at least one forming section 46 can have a parallel longitudinal course with respect to the first end face 19. It is also possible for the forming section 46 to be arranged or designed to run continuously along the first end face 19 in the circumferential direction. Regardless of this, it would also be conceivable for several forming sections 46 to be provided and for the forming sections 46 to be arranged at a distance from one another along the first end face 19 in the circumferential direction.

The deliberate additional shaping of the blank 13 in the area of its first end face 19 ensures that the previously described end section 47 with the first end face 19 located thereon forms or defines the at least one support element 41. In the erected position of the blank 13 relative to the outer part 12, the at least one support element 41 in turn defines the clear inner dimension 44, which is smaller than an inner dimension 45 of the outer part 12 in its undeformed configuration without the forming section 46. The bottom end of the outer part 12 is in the undeformed position indicated in dashed lines in FIG. 6.

Due to the design and shaping of the forming section 46, it may be necessary to make the undeformed height between the first and second end faces 19, 20 somewhat longer in order to subsequently achieve support on the shoulder 11 on the one hand and, on the other hand, to the immediately adjacent area to be able to cover the container jacket 4 to the flange 6.

[00137] However, it would also be possible to form the forming section 46 from the outer surface 42 in the direction of the inner surface 43 and thus form a type of kink.

To mutually connect the end sections 14, 15 of the previously flat blank 13 that face each other during the formation of the jacket, an adhesive layer 48 is preferably inserted or used in the overlap region 16 to be formed. This can be applied to one of the end sections 14 or 15 or to both of them, as is well known.

A major challenge is the separation, disposal and subsequent recycling of the different materials. The inner container 2 is usually made of a plastic or a degradable material that can be formed in a thermoforming process.

The outer part 12 is preferably formed from a cellulose material. The blank 13 can also be provided with a printed image on at least one of its flat sides, namely the outer surface 42 and/or the inner surface 43.

[00140] Since the process of separating the outer part 12 from the inner container 2 is usually not carried out or only partially carried out by the consumers, it can further be provided here that the adhesive layer 48 arranged in the overlap area 16 is designed in such a way that the first end section 14 and the second end section 15 in the overlap area 16 can be detached from one another again from the coupled state.

[00141] In particular, it can be provided that, viewed in the circumferential direction and thus in tension or shear, the adhesive has a sufficiently high adhesive force value in order to ensure sufficient mutual support of the two end sections 14, 15 under the usual loads on a filled combination packaging container 1 to ensure each other.

However, if a compressive force -F- is applied to an empty combination packaging container 1 that is therefore to be separated, and the outer part 12 and the container jacket 4 of the combination packaging container 1 are spatially deformed, then the adhesive force of the adhesive layer 48 can be exceeded and the End sections 14, 15 held together detach from one another at least in sections. The compressive force -F- can be applied to the combination packaging container 1 in a wide variety of directions and is at least partially converted into a separation force that at least partially separates the overlap area 16.

For example, compression can be carried out in the radial direction and/or also in the axial direction. The entire combination packaging container 1 is spatially deformed. With a compressive force -F- in the axial direction, the outer part 12 and also the container jacket 4 buckle in the direction of the longitudinal axis 8 and the overlap area 16 can thus be separated or carried out.

By providing or forming the additional support device 40 in the edge region immediately adjacent to the first end face 19, the cuff-shaped outer part 12 can be supported even better and more securely in the axial direction without the use or need for an additional adhesive on the shoulder 11 of the inner container 2 . The adhesive point between the inner surface 43 of the outer part 12 and the container jacket 4, which was previously additionally attached for safety reasons, can therefore be omitted and no longer needs to be provided. When separating the overlap area 16 with the adhesive used and/or separating the intended separation area 22, an undesired adhesive connection between the outer part 12 and the inner container 2 can be avoided.

This means that the user of the combination packaging container 1 can dispense with carrying out the separation process and can dispose of the entire combination packaging container 1. The separation process of the desired separation area 22 is then carried out mechanically by a press or a squeezing device or by the own weight of a large amount of waste during collection and / or waste disposal.

[00146] Furthermore, in order for one person to carry out the separation process, it would also be possible for the combination packaging container to be placed on a support surface either with its closed end or with its open end of the inner container and then to apply the pressure force -F- to the container facing away from the support surface End is exerted towards the support surface. Depending on the arrangement and setup of the combination packaging container, the compressive force can easily be applied to the combination packaging container and introduced into it, for example with human strength. The risk of injury can be minimized with the arrangement in which the pressure force is applied to the floor.

It would also be possible to exert the compressive force -F- on the combination packaging container in a parallel orientation with respect to a longitudinal axis extending between the open end and the closed end or in an orientation at an angle to the longitudinal axis. This means that when the force is introduced in parallel, the compressive force can simply be converted into a tearing force acting in a predominantly radial direction, at least to a large extent

be redirected, which leads to the outer part bursting open in its overlap area. If the force introduction direction deviates from this, the spatial deformation can also cause the overlap area to be separated.

If the previously described target separation area is also provided, the separation process of the combination packaging container 1 can optionally be carried out into its different components. This can be done either by a person or during the collection and disposal process.
