Description

I -SLEEVE-SHAPED OUTER PART; COMBINATION PACKAGING CONTAINER
EQUIPPED THEREWITH, AND METHOD FOR SEPARATING THE COMBINATION
PACKAGING CONTAINER
The invention relates to a sleeve-shaped outer part formed from a blank cut for encasing a cup-shaped inner container and to a combination packaging container formed from an inner container and the outer part. The invention further relates to a method for separating the com-bination packaging container into its inner container and the outer part by separating the over-lapping region of the outer part.
WO 2020/245148 Al shares the same applicant and describes a generic, sleeve-shaped outer part formed from a blank cut, wherein the blank cut is wound to form a jacket and its end por-tions are connected to each other in an overlapping region. A target separation region com-prises an actuating means with a detection portion for separating separation portions located on both sides. As seen in the circumferential direction, the detection portion is arranged at a lateral distance with an offset in relation to the separation portions, which are aligned so as to taper toward one another, and an imagined straight connecting line therebetween. An individ-ual target separation region is formed in the jacket of the outer part between each detection portion end and a respective end of the separation portions. The lower end face of the outer part facing the closed end of the inner container is supported on a supporting shoulder, which projects radially outwards, thereby achieving a form-fitting mutual holder between the outer part and the inner container within certain limits. The outer part may detach from the inner container in an undesirable manner because of manufacturing inaccuracies caused by toler-ance, a temperature change and/or moisture absorption of the blank cut preferably formed from a cellulose material.
WO 2009/130043 Al describes, inter alia, a sleeve-shaped outer part for forming a combina-tion packaging container. The outer part is formed from a blank cut by raising and connecting ends to one another in an overlapping region. Furthermore, an actuating means for separating a target separation region is provided, which is arranged between the two end regions spaced apart from one another in the axial direction. The actuating means is formed by an opening extending up to the overlapping region, wherein the longitudinal side of the overlapping end forms the detection portion. In a further embodiment, an actuating tab, which can be released from the jacket in a U-shaped circumferential line, is provided, in which the weakening line

- 2 -delimiting the actuating tab ends at the longitudinal side of the overlapping end. Though this design has proven itself in principle, it has not been possible to achieve perfect separation of the target separating region adjoining the actuating means in all applications.
EP 2 338 804 B1 addresses a packaging container with a first container part, having a con-tamer bottom and a container wall extending from the container bottom in the direction of a container edge, and a second container part, which reinforces the container wall and is in the form of a sleeve, which is detachably connected to the first container part and abuts at least partially against the outer surface of the container wall.
The second container part has a weakening line running from an upper edge of the second container part facing the container edge in the direction of a lower edge of the second con-tainer part facing the container bottom. The second container part can be detached from the first container part by separating the second container part along the weakening line. The sec-ond container part further has a gripping region to be gripped manually for separating the sec-ond container part, the second container part being detachable from the first container part from said region. The weakening line has an engagement section delimiting the gripping re-gion with a reinforced weakening and/or a cutting line, which forms the starting section for separating the second container part along the weakening line. Furthermore, an access area adjoining the gripping area and located on the side of the weakening line opposite the grip-ping area is provided, said access area having two target separation lines running transversely to the weakening line, which end on one side in the engagement section of the weakening line. The result thereof is that, after separation along the target separation lines and the en-gagement section, the access region remains firmly connected to that edge region of the sec-ond container part that does not have the gripping region. It has not been possible to achieve perfect separation of the target separating region that adjoins the gripping region in all appli-cations either.
Further packaging containers are known from US 2012/205480 Al, US 2018/808880 Al, US
5 385 260 A, US 2008/087877 Al, DE 20 2004 015374 Ul and EP 2 128 041 Al It was an object of the present invention to overcome the disadvantages of the prior art and to provide a sleeve-shaped outer part and a combination packaging container, comprising a cup-shaped inner container with a sleeve-shaped outer part surrounding it, in which the sleeve-

- 3 -shaped outer part is arranged in position and held securely on the inner container in the axial direction without additional adhesives until desired detachment from the inner container for recycling purposes. However, a further method for separating the overlapping region and the subsequent separation of its outer part and inner container was also intended.
This problem is solved by a sleeve-shaped outer part and a combination packaging container comprising the outer part and an inner container in accordance with the claims.
The sleeve-shaped outer part according to the invention is used for encasing a cup-shaped in-ner container to form a combination packaging container wherein the inner container has a container jacket configured particularly to taper conically from an open end towards a closed end with a bottom wherein the outer part is formed from a blank cut, said blank cut being wound into a jacket in its raised state, and a first end portion and facing it a second end portion of the jacket are connected to one another in an overlapping region wherein the outer part further has a first end face and a second end face, the two end faces spaced apart from one another, and in the raised state, define a structural height of the jacket with a longitudinal axis extending in the direction of the structural height, wherein the first end face defines a support region in sections at least and, furthermore, the first end face can face the bottom and the second end face the open end of the inner container, and an additional support device is further provided, said additional support device be-ing arranged or formed in the region of the first end face of the outer part formed from the blank cut, and the additional support device defines a clear internal dimension, which is smaller than an inner dimension of the outer part in its undeformed configuration in the region of the first end face.
The resulting advantage is that the support region or support portion already defined by the first end face on the shoulder of the inner container is further improved by the provision or formation of the additional support device. In the undeformed configuration of the bottom end region of the blank cut or of the outer part formed therefrom, the additional support device re-duces the clear inner dimension with respect to the undeformed configuration, thereby achiev-ing an even better latching effect on the inner container. Manufacturing inaccuracies caused by tolerance therefore result in no further disadvantages in the stationary positioning of the

- 4 -outer part on the inner container, even without the adhesive point usually applied for securing purposes between the container jacket and the outer part. This creates an outer part that can also be detached more easily from the inner container for disposal.
An advantageous configuration provides 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, starting from the undeformed bottom-side edge region or edge portion of the outer part, projects in the direction of the longitudinal axis and forms the reduction of the clear internal dimension.
Furthermore, it can be advantageous for the at least one support element to be moulded into the material of the blank cut starting from an outer surface of the outer part in the direction of an inner surface and projecting in the radial direction beyond the undeformed inner surface in the direction of the longitudinal axis. The material can thus be used directly to form the at least one support element, meaning additional components or component components can thus be dispensed with. No additional material is therefore used, which 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 longitudi-nal extension starting from the first end face in the direction of the second end face. Thus, a defined projection of the at least one support element beyond the inner surface of the blank or outer part can be realised, which forms the enlargement or widening of the bottom-side sup-port region.
A further possible embodiment has the features that a plurality of support elements are pro-vided and the support elements are arranged spaced apart from one another along the first end face in the circumferential direction. As a result, it is possible to achieve an even better sup-porting effect over the circumference even under changing environmental conditions and/or during handling.
A further configuration provides that the additional support device comprises at least one forming portion, which is moulded into the material of the blank cut starting from an inner surface of the outer part in the direction of an outer surface, the at least one forming portion being arranged at a distance from the first end face. An alignment of the edge portion in the opposite direction can consequently be formed.

- 5 -Another embodiment is characterized in that the at least one forming portion, viewed in axial section, has a preferably curved longitudinal extension and an end portion adjoining the form-ing portion in the direction of the first end face oriented so as to be inclined in the direction of the longitudinal axis. This achieves additional stiffening of the bottom-side end portion or pe-ripheral edge region.
A further preferred embodiment is characterized in that the at least one forming portion has a parallel longitudinal extension in relation to the first end face. This achieves uniform configu-ration of the additional support device projecting in the direction of the inner container.
Furthermore, it can be advantageous for the forming portion to be arranged so as to extend continuously along the first end face in the circumferential direction. This achieves a reliable and uniform supporting effect over the entire circumference, in particular for inner containers with a round cross-sectional shape.
Another alternative embodiment is characterized in that a plurality of forming portions are provided, the forming portions being arranged spaced apart from one another along the first end face in the circumferential direction. This alternative can be used in particular for inner containers with container walls running rectilinearly as seen in cross section, which each have a rounded corner region in transition regions located therebetween. This avoids the undesired formation of folds in the transition regions.
A further configuration intends for an adhesive to be provided in the overlapping region be-tween the two end portions, said adhesive having a first adhesive force value as seen in the circumferential direction and having a second adhesive force value in the radial direction, wherein the first adhesive force value is greater than the second adhesive force value. Cohe-sion can be formed at a higher level when viewed in the circumferential direction as a result of the differing adhesive force values of the adhesive holding the blank cut together at its end portions facing one another one the one hand, and on the other hand, when force deviating therefrom is applied, this enables a lesser separating effect with reduced adhesive force. This facilitates the separation process of the overlapping region when the outer part is separated from the inner container. If compressive force is exerted in the direction of and on the inner container, this can easily lead to mutual detachment of the two end portions connected to one

- 6 -another, consequently enabling a simple separation process of the outer part from the inner container during disposal.
Another embodiment is characterized in that at least one target separation region is formed or provided in the jacket of the outer part. A further detachment option of the outer part from the inner container is intended by providing the outer part jacket with an individual target separat-ing region. This enables the user or consumer of the combination packaging container to cany out targeted separation thus properly separating the materials in a known manner after con-suming the contents.
The invention also relates to a combination packaging container comprising a cup-shaped in-ner container with a container jacket, a bottom, a flange, an undercut located in the bottom re-gion of the container jacket and a shoulder, as well as a sleeve-shaped outer part configured according to the invention, which at least partially surrounds the inner container on its con-tainer jacket.
This creates a combination packaging container, in which an even better and safer hold of the outer part on the inner container is achieved in the axial direction of the direction or side fac-ing away from the open end, meaning that more leeway is provided for manufacturing toler-ances related to production.
A further configuration provides that the sleeve-shaped outer part is supported in the axial di-rection on the shoulder of the inner container by means of its additional support device with-out using an additional adhesive. Thus, after the combination packaging containers have been used, separating it is even easier and above all safer to separate them into the inner container and the outer part. Even after the separation process of the outer part, the outer part forms a piece that belongs together, which can be fed simply and above all in one piece to the proper disposal and recyclable materials collection. Dispensing with the additional adhesive means a saving and also avoiding possible contamination of the machine when applying the adhesive.
However, the problem of the invention is also solved by a method for separating an outer part from an inner container, which together form the combination packaging container, in that during the separation process, a compressive force -F- directed in the direction of the combi-nation packaging container is applied and in the process the outer part and the container jacket of the combination packaging container are spatially formed and the applied compressive

- 7 -force -F- is at least partially converted by the spatial formation into a separating force, which at least partially separates the overlapping region.
The compressive force -F- applied leads to a spatial deformation of the outer part and also of the container jacket, as a result of which the compressive force -F- is at least partially de-flected and converted into a separating force. In this way, the overlapping region of the outer part, which is held together by means of the adhesive, is acted upon by the separating force acting in the radial direction, depending on the orientation of the compressive force -F-. The separating force acting on the overlapping region effects the separating process of at least the overlapping region. This can render searching for and finding the actuating means for the tar-get separation region and the subsequent tearing operation superfluous for the person carrying out separation.

The term "in particular" is understood in the following to be a possible, more specific config-uration or further specification of subject matter or a method step but not necessarily to mean a mandatory, preferred embodiment of the same or a mandatory procedure.
In their present use, the terms "comprising", "has", "having", "includes", "including", "con-tains", "containing" and any variations thereof are intended to be non-exclusive in nature.
A further term, "optional(ly)" can also be used. This is understood to mean that this method step or plant component is basically present, but is only used depending on the operating con-ditions, though this does not necessarily have to take place.
The present application is an advancement of WO 2020/245148 Al of the same applicant, which was already mentioned in the preamble to the description and builds thereupon. In these combination packaging containers, the blank cut, the outer part formed therefrom and the inner container are manufactured separately from one another. After the blank cut has been wound to form the sleeve-shaped outer part, either the outer part is pushed onto the inner container in the axial direction or the inner container is pushed in the axial direction into the outer part, which is held in position for the joining process. EP 0 929 455 B1 describes push-ing the outer part onto the inner container in detail. Joining the inner container to the outer part is described in detail in EP 1 463 670 BI. Such an embodiment of the outer lining of a cup or a dish is the subject of the following description.
Fig. 1 to 4 show a combination packaging container 1 as an example for a plurality of possible different shapes, the combination packaging containers 1 being formed in the shape of cups or dishes. The combination packaging container 1 comprises an inner container 2 configured in the shape of a cup or dish with a bottom 3 and a container jacket 4.
Furthermore, the inner container 2 has an open end 3 on its side facing away from the bottom 5, wherein a flange 5 projecting outward from the container jacket 4 can be provided in the region of its open end 6.
The bottom 3 forms a closed end 4 for the container jacket 7.

, t

- 9 -The inner container 2 is preferably formed by a component produced in a deep-drawing pro-cess, which can be produced quickly and above all in a short cycle time. The process of deep-drawing is well known and therefore requires no further explanation. The deep-drawing pro-cess is particularly suitable for producing the inner container 2 with a sufficient wall thickness from a layer of a formable material to be formed by means of a deep-drawing tool, said wall thickness ensures sealing during storage, use and disposal. This manufacturing process ena-bles the production of relatively thin inner container 2 wall thicknesses.
However, the inner container 2 can also be shaped by means of other manufacturing methods, e.g.:
by an injection moulding process As a result of the cup-shaped or dish-shaped configuration of the inner container 2, a longitu-dinal axis 5 extends in the axial direction between the open end 3 and the closed end 7 with the bottom 8, which can also represent a central axis in a symmetrical configuration. It is pos-sible to arrange or connect a sealing lid (not shown in detail) in the region of the flange 6. In this case, the flange 6 forms a sealing flange.
In the axial direction and thus in the direction of the longitudinal axis 8, the inner container 2 has a container height 5 between its open end 6, in particular the flange 3, and the bottom 9, as a result of which the receiving volume of the inner container 2 is determined as a function of the cross-sectional dimensions. A receiving space of the inner container 9 is thus defined by the container height 2 in conjunction with the cross-sectional dimensions.
The container jacket 4 is understood to be that portion of the inner container 2, which extends in the predominantly axial direction between the open end 5, in particular the flange 6, and the bottom 3. The inner container 2 with its container jacket 4 is preferably configured in such a way that it preferably tapers conically starting from the open end towards the bottom.
Furthermore, the container jacket 4 of the inner container 2 can have an undercut 3 in its cir-cumferential portion adjacent to the bottom 10. The undercut 10 is also part of the container jacket 4, but, viewed in axial section, is arranged offset inwardly with respect to an imagined, rectilinear connecting line between the flange 6 and the bottom 3. The undercut 10 itself has at least two undercut wall portions not described in further detail, the two undercut wall por-tions having a different inclination or direction with respect to the longitudinal axis 8, as seen

- 10 -in axial section, than the rest of the container jacket 4. For this purpose, the undercut 10 is ar-ranged between the flange 4 and the bottom 6 inwardly and thus offset in the direction of the receiving space in relation to the arrangement of the container jacket 3, which extends in a rectilinear manner as seen in axial section.
Viewed in axial section, the first undercut wall portion directly adjoining the bottom 3 is ar-ranged or configured to extend predominantly in the direction of the container height 9 to-wards the open end 5. The further undercut wall portion extends in a predominantly vertical direction in relation to the container height 9, starting from the end of the first undercut wall portion facing away from the bottom 3, towards the container jacket 4.In the present embodi-ment, the further undercut wall portion forms a stacking shoulder. This stacking shoulder serves to support a similar combination packaging container 1 with its bottom 333, in particu-lar the edge-side transition portion between the bottom 4.
Furthermore, the inner container 2 can be provided with a shoulder 3 or a bead projecting on the side facing away from the longitudinal axis 4 the immediate transition region between the bottom 3 and the container jacket 8, in particular between the bottom 11 and the undercut.
The combination packaging container 1 further comprises an outer part 12, which is formed to be cuff shaped or jacket shaped and surrounds the inner container 2 in the region of its con-tainer jacket 4 at least in portions or regions.
The above-described shoulder 11 can serve to hold the cuff-shaped outer part 12 on the inner container 2, for example. In this case, the sleeve-shaped outer part 12, with its first end face 3 facing the bottom 2 of the inner container 19, is supported on this shoulder

11 formed in the transition region. The shoulder 11 can therefore also be referred to as a latching means for holding the outer part 12 on the inner container 2. In its longitudinal extension, the end face 19 forms an end edge, which, in the joined position, defines a support region and is supported so as to adjoin the shoulder at least in sections. Depending on the radial projection of the shoulder 11 and the dimension of the outer part 12 caused by tolerance, an undesired detach-ment of the outer part 12 from the inner container 2 may occur.
The flange 5 can represent a further latching means in the region of the open end 6, for exam-ple. Furthermore, the sleeve-shaped outer part 12 comprises a second end face 20, which in turn faces the open end 5 or the flange 6.

The sleeve-shaped outer part 12 is preferably formed from a cellulose material, such as a cardboard material, with sufficient strength with respect to the absorption and transmission of, in particular, axially acting compressive forces, and is wound from a planar blank cut 13 to form a jacket, as is already sufficiently known. The blank cut 13 is usually printed upon in its undeformed planar position and, as required, also provided with an additional coating. A cel-lulose material is usually used as the material, although this can also be a cardboard or strong paper produced by recycling. If a layer of the outer part 12 is formed from a recycled material, an additional layer of a higher quality paper can be arranged on or connected to at least one of the surfaces. This additional layer enables perfect printing for the production of decorations, inscriptions and product information.
The sleeve-like or jacket-like outer part 12 offers an additional reinforcement or stiffening ef-fect of the inner container 2 and thus of the entire combination packaging container 1.
This offers high strength and good thermal insulation on the one hand and optimal light pro-tection for the packaging container contents on the other hand.
It can also be particularly provided that the cardboard be additionally coated or sealed with a water-repellent material in the region of the cut edges. This is particularly advantageous if the combination packaging containers 1 are exposed to high levels of moisture. The coating of the cardboard used for the outer part 1212 with a water-repellent layer prevents swelling of the cardboard in a moist environment and ultimately detachment from the container jacket 4 of the combination packaging container.
The sleeve-shaped outer part 12 is wound from the mostly planar blank cut 13 to form a jacket. By winding the blank cut, end portions 14, 15 facing one another are connected to one another in an overlapping region 16 shown in a simplified manner. This is achieved by what is known as an overlap seam, with which the first end portion 14 and the second end portion 15 adhere to one another by means of an adhesive, for example. The winding and the subse-quent connection of the two end portions 14, 15 can take place, for example, with adhesive bonding, as is already sufficiently known from the prior art. Reference is made to EP 0 408 515 B1 as an example here. The first end portion 14 of the blank cut 13 ends with a first lon-gitudinal edge 17 and the second end portion 15 in turn ends with a second longitudinal edge 18. In the overlapping region 161617, the two longitudinal edges 18, 16 having an overlap width formed therebetween viewed in the circumferential direction.
The outer part 12 further has the first end face 191920 and the second end face 192020, the two end faces 21 of the jacket in the raised state. The above-described longitudinal axis 8 can

- 12 -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. The structural height 21 of the jacket is mostly slightly less 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 configuration for the separating the outer part 12 from the inner container 2 is described in the following. This is what is known as a target separation region 22, which is arranged and configured in the material or material of the outer part 12 The following detailed description of the target separation region 22 corresponds to the configuration as already described in WO 2020/245148 Al. However, the target separa-tion region 22 could also be configured in a different and deviating manner.
In order to enable a defined separation and a resulting subsequent separate disposal of the in-ner container 2 and outer part 12 for a consumer, at least one target separation region 22 is provided. In this case, the desired separation region 22 comprises a first separation section 23, a second separation section 24 and an actuating means 25 for starting and beginning the sepa-ration process of the desired separation region 22 along the two separation sections 23, 24.
The actuating means 25 is arranged between the two end faces 21, 19 viewed in the direction of the structural height 20 of the jacket. In this case, it is advantageous for the actuating means to be arranged approximately centrally between the two end faces 21, 19 spaced apart from one another in the direction of the structural height 202121, this corresponding essentially to 20 half the structural height 21. In regard to the actuating means 25, the indication "central" re-fers to half of its size in the direction of the structural height 21 or the longitudinal axis 8. The two separating portions 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.
Viewed in the direction of the structural height 21 of the jacket, the two separating portions 25 23, 24 of the target separation region 22 are each aligned so as to converge from the two end faces 19, 20 and thus define between them an imagined, rectilinear connecting line 26, the lat-ter being shown in dashed lines. The converging alignment of the two separating portions 23, 24 is in relation to the direction towards the actuating means 25 in each case. The two separat-ing portions 23, 24 can either be aligned with one another as viewed in the direction of the structural height 21 of the jacket, or they can also extend with at a slight incline with respect to the first longitudinal edge 17 in the direction of the actuating means 25 located between

- 13 -them. This slight inclination leads to additional improvements in the separation process after the two separation portions 23, 24 have been separated up to the two end faces 19, 20.
Depending on the configuration of the target separation regions to be described in more detail below, the imagined connecting line 26 is assumed to extend in a means of the target separa-tion regions. The actuating means 25 in turn defines a detection portion 27 with a first detec-tion portion end 21 and a second detection portion end 28 located at a distance from one an-other in the direction of the structural height 29. Thus, the two detection portion ends 28, 29, viewed in the direction of the structural height 21 of the jacket, are arranged at a distance 30 from one another or end there. Furthermore, it can also be seen that the detection portion 27 of the actuating means 25 is arranged or formed outside the overlapping region 16.
In this case, an arrangement of the actuating means 25 is provided, in which the detection por-tion 27, viewed in the circumferential direction, is arranged or formed at a distance laterally by an offset 23 with respect to the separating portions 24, 22 of the target separation region 26 and the straight connecting line 31 imagined therebetween. The offset 31 can have a value se-lected from a range of values with a lower limit of 1.0mm and an upper limit of 10.0mm. The value range can preferably have a lower limit of 2.0mm and an upper limit of 6.0mm.
The first separating portion 23 itself has a first end 25 facing the actuating means 32, whereas the second separating portion 24 has a second end 25 facing the actuating means 33. In the re-gion of the imagined connecting line 26 between the two ends 32, 33, the jacket is configured without interruption due to the provided lateral offset 31 of the actuating means 25. The ar-rangement of the two ends 21, 32 of the separating portions 332323, 242425 spaced apart from one another in the direction of the structural height 27 with respect to the detection por-tion 28 that forms the actuating means 27 is selected such that the first detection portion end 32 of the detection portion 23 overlaps the adjacent first end 24. As a result of the lateral off-set 31 of the detection portion 27 on the side facing away from the overlapping region 16, a first target separation section 34 is formed, viewed in the circumferential direction, in the jacket of the outer part 12 between the first detection portion end 28 and the first end 32 of the first separation portion 23.
It is also intended for the second detection portion end 29 of the detection portion 27 to over-lap the adjacent second end 33 of the second separation portion 24 on the side facing away from the first separation portion 23. Thus analogously to the first target separation region 34, a second target separation region 29 is also formed in the jacket of the outer part 33 between the second detection portion end 24 and the second end 35 of the second separation portion s =
¨ 114 -12. The two target separation portions 34, 35 are formed by the reduced dimension of the jacket material between the respective detection portion end 28 or 29 and the respective end 32 or 33. The two ends 32 and 33 of the separating portions 23, 24 are arranged closer to one another than the two detection portion ends 30 and 28 spaced apart from one another by the distance 29.
This makes it possible for a user of the combination packaging container 1 to detect the actu-ating means 25 with its detection portion 2727, subsequently to separate the two target separa-tion portions 3427 starting from the detection portion 32 up to the respective ends 33, 23 of the two separating portions 242323, 24 until the jacket has been completely separated. By do-ing so, the outer part 12 can be easily separated from the inner container 2 and a disposal can take place in a sorted manner. The two target separation portions 34, 35 each form starting portions for the separation of the two separation portions 23, 24.
Each of the two separating sections 23, 24 comprises a plurality of target separation points ar-ranged in series in a row, which are typically configured as perforations, in particular also as short cuts, in the material of the outer part 12.
This embodiment shows that the shape and position of the target separation points can be se-lected differently from one another. For this reason, target separation points arranged directly adjacent to the respective detection portion ends 28, 29 are designated first target separation points 36. The further target separation points provided respectively in the subsequent direc-tion toward one of the two end faces 19, 20 are designated second target separation points 37 and third target separation points 38.
The target separation points 36, 37, 38 are configured and arranged in a mirror-image manner with respect to one another and to a plane 8-see Fig. 1 - aligned centrally and in normal align-ment to the longitudinal axis 39.Therefore, only those target separation points 23, 36, 37 lo-cated in the region of the first separation portion 38 are described in more detail and should be transferred to the second separation portion 24 by analogy.
Furthermore, it is also shown in the lower left corner region of the combination packaging container 11 shown in section in Fig. 1 and in the enlarged representation thereof in Fig. 2 that an additional support device 40 is provided or formed in the region or in the portion of the first end face 19 of the blank cut 1313 or of the outer part 40. The additional support de-vice 40 serves or is configured to ensure that the outer part 12 is or becomes even more se-curely supported on the shoulder 2 of the inner container 11 in the axial direction until it is de-tached therefrom. The additional support device 40 is further configured such that a clear in-ternal dimension of the ready formed outer part 12 is smaller in relation to the undeformed configuration. The bottom-side end face 19 of the outer part 12 already forms or defines the support portion that cooperates with the shoulder 11, which is further improved, in particular enlarged, and made more secure by the provision or formation of the additional support de-vice 40.
In this first embodiment shown here, the additional support device 40 comprises at least one support element 414119, but preferably a plurality of support elements 41 arranged at a dis-tance from one another along the first end face 12. The individual support elements 41 are moulded into the material of the blank cut 131313. The support elements 41 are moulded starting from an outer surface 42 of the outer part 12 in the direction of an inner surface 43 and are thus formed. Thus, these project in the radial direction over the undeformed inner sur-face 43 in the direction of the longitudinal axis 8. The projection can have a value from a value range with a lower limit of 0.05mm, in particular 0.1mm, and an upper limit of 0.5mm, in particular 0.2mm.
A clear inner dimension 44 of the additional support device 41 formed by the supporting ele-ments 40 is thus smaller than an internal dimension 45 of the outer part 12 in its undeformed configuration without the supporting elements 41. By moulding the at least one support ele-ment 41, the first end face 19 is also formed along its longitudinal extension and thus also forms a support surface for the outer part 12 on the shoulder 11. The longitudinal extension can also be formed in the form of a longitudinal corrugation.
The support element 414141 or the support elements 19 have a longitudinal extension starting from the first end face 20. Thus, the support element 414141 or the support elements 19. The length of the at least one support element 41 can be, for example, a few millimetres and de-pends on the size and configuration of the undercut 10. Possible examples are 2mm to 15mm, preferably 5mm to 1 Omm. The cross-sectional shape of the support element 414141 is only shown by way of example. Instead of the rather angular cross-sectional shape here, a rounded or arcuate cross-sectional shape would also be conceivable.
In Fig. 4, the blank cut 13 for forming the outer part 12 described above in Fig. 1 to 3 is shown in its undeformed, planar position, wherein the same reference numerals or component designations as in the preceding Figs. 1 to 3 are used for identical parts. To avoid unnecessary repetitions, reference is made to the detailed description in preceding Figures 1 and 3.
The previously described target separation region 22 is not shown in detail here, but can also be provided as has already been described above as a possible and optional alternative. Fur-thermore, the orientation of the individual support elements 41, starting from the first end face 19 facing the floor in the direction of the second end face 20, can be better seen here. Due to the arcuately curved longitudinal extension of the two end faces 19, 20 and their joint centre (centre of the radius), the individual support elements 41 also have a longitudinal extension oriented towards the centre.
Fig. 5 and 6 show a further and possibly independent embodiment of the outer part 13 formed from the blank cut 12 to form the jacket, again using the same reference numbers or compo-nent designations for the same parts as in the preceding Fig. 1 to 4. To avoid unnecessary rep-etitions, reference is made to the detailed description in preceding Figures 1 and 4 It is worth noting here that it is once again optionally possible to provide or to configure the target separation region 22 already described in detail above. For the sake of clarity and to avoid unnecessary repetition, the depiction and description of the latter have been dispensed with.
For their part, the blank cut 13 and the outer part 12 formed therefrom comprise the additional support device 40, which, however, has a different configuration to the embodiment described above. By doing so, the additional support device 40 for forming the same comprises at least one forming portion 46, which is also moulded into the material of the blank cut 13. In con-trast to the embodiment described above, the at least one forming portion 46 is moulded start-ing from the inner surface 43 of the outer part 12 in the direction of its outer surface 42. Fur-thermore, the at least one forming portion 46 is arranged at a distance from the first end face 19 in the direction of the opposite second end face 20.
Viewed in axial section, the at least one forming portion 46 can have a longitudinal extension that is mostly curved outward. An end portion 46 adjoining the at least one forming portion 19 is provided in the direction of the first end face 47 and located thereupon, thereby forming or arranging a corresponding end portion 46 adjacent to each forming portion 47. The end portion 47 itself can be oriented so as to be inclined in the direction of the longitudinal axis 8.

As can now be better seen from Fig. 5, the at least one forming portion 46 can have a parallel longitudinal extension in relation to the first end face 19. It is also possible for the forming portion 46 to be arranged or configured to extend continuously in the circumferential direction along the first end face 19. However, independently of this, it would also be conceivable for a plurality of forming portions 464646 to be provided, the forming portions 19.
Deliberate, additional shaping of the blank cut 13 in the region of its first end face 191947 re-sults in the previously described end portion 19 with the first end face 41.
In the raised posi-tion of the blank cut 41 with respect to the outer part 131212, the at least one supporting ele-ment 44 in turn defines the clear inner dimension 45, which is smaller than an internal dimen-sion 12 of the outer part 46. The bottom end of the outer part 12 is indicated in the unde-formed position in dashed lines in Fig. 6.
As a result of configuring and moulding the forming portion 46, it may be necessary to con-figure the undeformed height between the first and second end faces 19, 20 to be somewhat longer in order to subsequently achieve, on the one hand, support on the shoulder 11 and on the other hand, to be able to cover the container jacket 6 up to immediately adjacent to up to the flange 4.
However, it would also be possible to mould the forming portion 46 from the outer surface 42 in the direction of the inner surface 43 and thus forming a type of kink.
To mutually connect the end portions 14, 15 of the previously planar blank cut 13 facing one another during formation of the jacket, an adhesive is preferably used in the overlapping re-gion 16 to be formed. Said adhesive can be applied to one of the end portions

14 or 15 or to both as is well known.
Separation, disposal and subsequent recycling of the different materials is a significant chal-lenge. The inner container 2 is mostly formed from a plastic or degradable material, which can be shaped in a thermoforming process. The outer part 12 is preferably formed from a cel-lulose material. The blank cut 13 can further 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.

. s As the separation process of the outer part 12 from the inner container 2 is usually not carried out or is only carried out partially by the consumer, it can further be provided that the adhe-sive used in the overlapping region 16 has different adhesive force values relative to one an-other depending on the force direction acting thereon, in particular the separation direction, for this purpose.
Viewed in the circumferential direction and thus in respect of tension or shear, the adhesive should have a sufficiently high adhesive force value in order to ensure sufficient mutual hold of the two end portions 14, 15 to one another under the usual loads.
However, if a compressive force -F- is applied to the combination packaging container 1 to be separated, the adhesive has a second adhesive force value differing from the first adhesive force value. The first adhesive force value should be greater than the second adhesive force value. 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 separating force at least partially separating the overlapping region 16. In this case, the second adhesive force value is exceeded and the two end portions 14, 15 first held together by the adhesive detach from one another at least in sections.
Compression can be carried out in the radial direction and/or also in the axial direction in this way, for example. In doing so, the entire combination packaging container 1 is spatially de-formed. In the event of a compressive force -F- in the axial direction, both the outer part 12 and the container jacket 4 buckle in the direction of the longitudinal axis 8 and the separation of the overlapping region 16 can thus take place or be carried out due to the lower adhesive force value in this direction of force.
By providing or forming the additional support device 404019 in the edge portion immedi-ately adjacent to the first end face 12, the sleeve-shaped outer part 40 can be even better and more securely supported in the axial direction without using an additional adhesive by means of its additional support device 11 on the shoulder 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 thus be dispensed with and no longer need be provided. Thus, when the overlapping region 16 is separated with the adhesive used in the process and/or when the target separation region 22 is separated, an adhesive bond still undesired between the outer part 12 and the inner container 2 can be avoided.
Thus, the user of the combination packaging container 111 to the disposal. The separation process of the target separation region 22 is then carried out mechanically by a press or a squeezing device during collection and/or during waste disposal.
Furthermore, in order for a person to carry out the separation process, it would also be possi-ble to place the combination packaging container on a supporting surface either with its closed end or with its inner container open end, and subsequently for the compressive force -F- to be applied to the end facing away from the supporting surface in the direction of the sup-porting surface. Depending on the arrangement and positioning of the combination packaging container, the compressive force can thus easily be applied to the combination packaging con-tainer and introduced into it with human force, for example. That arrangement in which the compressive force is applied to the bottom can minimise the risk of injury.
It would also be possible to exert the compressive force -F- onto the combination packaging container in a parallel alignment with respect to a longitudinal axis extending between the open end and the closed end or in an alignment at an angle thereto with respect to the longitu-dinal axis. Thus, when force is introduced in parallel, the compressive force can simply be de-flected into a tearing force acting predominantly in the radial direction for the most part, which causes to the outer part to burst in its overlapping region. Should a deviating force be introduced, the separation of the overlapping region can also be brought about by the spatial deformation.
If the above-described target separation area is also provided, the separation process of the combination packaging container linto its different components can be carried out optionally.
This is done either by a person or in the course of the collection and disposal process.
