Description

[0001] The invention relates to a blank, a cuff-shaped outer part formed from a blank for encasing a container, in particular a cup-shaped one, and a combination packaging container formed from a container and an outer part. The invention further relates to a method for manufacturing a combination packaging container and a method for opening a combination packaging container.

[0002] Due to increasingly stringent environmental requirements for products and product packaging, enabling recycling, and in addition to recycling, reuse, is becoming ever more important. Recycling should allow for the separation of different materials by type to improve recycling quality. In particular, the separation of different materials by type should be made as simple as possible so that any human oversights or errors during the recycling process can be compensated for as much as possible. Furthermore, used products and product packaging should be processed into reusable products and product packaging in a simple and sustainable way.

[0003] WO 2020 / 245148 A1 describes a cuff-shaped outer part formed from a blank, wherein the blank is wound into a sheath and its end sections are joined together in an overlap area. The cuff-shaped outer part, together with a cup-shaped inner container, forms a combination packaging container. A predetermined separation area comprises an actuating element with a detection section for separating the separation sections located on both sides. With such a combination packaging container, the predetermined separation area is intended to be separated after use of the container; therefore, separation of the components and subsequent recycling or reuse is not guaranteed.

[0004] Furthermore, it has become apparent that resealing is particularly problematic with containers intended for reuse, i.e., reusable containers. For example, repeatedly resealing the edges of reusable containers is difficult because the sealing plates often do not adhere or adhere only inadequately.

[0005] The object of the present invention was to overcome the disadvantages of the prior art and to provide a blank, an outer part and a combination packaging container in which the cuff-shaped outer part can be easily removed from the container for recycling purposes, and in which it is also ensured that a user carries out this separation, while at the same time aiming to improve the sealability and durability of container closures, in particular of reusable containers.

[0006] In the context of the invention, the term container encompasses a variety of conceivable shapes, configurations, and uses. It can be a cup-shaped container, but equally a tub-shaped, bowl-shaped, or bottle-shaped container.

[0007] The invention relates to a blank for an outer part for encasing a container, in particular a cup-shaped container, which has a container shell having an open end and an end closed with a bottom, wherein the blank has a substantially annular segment-shaped basic form, wherein the blank has a first end section and a second end section, wherein the blank can be wound into a shell and the first end section and the second end section can be coupled together in an overlap area, wherein the blank further has a first end face and a second end face and wherein the first end face and the second end face are spaced apart from each other, wherein the blank has a longitudinal extension in a direction starting from the first end face to the second end face.

[0008] The design provides that the blank has a fold line and a fold area, wherein the fold line, in a flat, i.e., unwound, state of the blank, is concentric with respect to the center point of the circular segment-shaped base form, and wherein the fold area, viewed longitudinally, is located between the fold line and the second end face, and wherein the fold area is foldable along the fold line. "Folding" here refers in particular to crimping, hemming, or fan-shaped or fan-like folding.

[0009] The inventive blank offers the surprising advantage that the folding area and fold line ensure that the blank and any container, particularly a cup-shaped one, wrapped with the blank must be separated to allow access to the contents contained within. This allows for improved separation and recycling in a particularly simple and visually appealing manner. Furthermore, the blank can form a high-quality and attractive outer packaging for a container, and can also serve as proof of authenticity, thus acting as "tamper evident." In addition, the folded area contributes to the protection of a closure element, such as a sealing plate or a thin lid, thereby increasing its stability and durability, especially with regard to accidental punctures.Furthermore, in the case of a sealing plate or similar closure element, the sealing areas or edges are protected and therefore subject to little or no stress. This further contributes to durability and improves the protection of the contents of the container, such as pasty or liquid contents like dairy products, but also powdered contents or bulk materials of any kind.

[0010] The cut-out material is particularly, but not exclusively, suitable for wrapping reusable containers, especially reusable plastic containers or plastic cups. After being separated from the wrapped container as required for its use, the cut-out material can be recycled in a largely sorted manner, while the container itself can undergo a reuse process.

[0011] The cut-to-size piece can be a part cut from a sheet or a sheet-shaped element, for example, from paper, cardboard, or even a thin sheet of plastic. Composite materials made of paper, cardboard, and / or plastic, or with a thin metal layer, are also conceivable. Aluminum-containing foils are also possible.

[0012] The invention also relates to an outer part for encasing a container, in particular a cup-shaped container, which has a container shell having an open end and an end closed with a bottom, wherein the outer part is formed from a blank, in particular from a blank according to the claims, which blank has a substantially annular segment-shaped basic form, which blank has a first end section and a second end section, wherein the blank is wound to form a shell and the first end section and the second end section are coupled to each other in an overlap area, wherein the outer part further has a first end face and a second end face and the first end face and the second end face are spaced apart from each other, wherein the outer part has a longitudinal extension in a direction starting from the first end face to the second end face.

[0013] The outer part is designed to have a fold line and a fold area, or crimp area, wherein the fold line is concentric to the outer part's longitudinal axis, and wherein, in its unfolded state and viewed longitudinally, the fold area is located between the fold line and the second end face, and wherein the fold area is foldable or crimpable along the fold line in a radial direction to the outer part's longitudinal axis, such that the open end can be at least partially covered or closed by the fold area. "Folding" here refers in particular to crimping, flanging, or fan-shaped or fan-like folding.

[0014] It is possible that the fold line and / or fold area is already pre-folded, pre-crimped or pre-hemmed before wrapping a container with the outer part, or that the fold line and / or fold area is only folded, crimped or hemmed after wrapping a container with the outer part.

[0015] The outer part according to the invention offers the surprising advantage that, due to the folding area and the fold line, the outer part and a container, particularly a cup-shaped one, wrapped with the outer part, must be separated to allow access to the contents contained within the container. This ensures improved, and in particular reliably guaranteed, separation and recycling in a particularly simple and visually appealing manner. Furthermore, the outer part can form a high-quality and attractive outer packaging for a container, and can also serve as proof of authenticity, thus acting as "tamper evident."Furthermore, the folded edge protects a sealing element, such as a sealing plate or a thin lid, thus increasing its stability and durability, particularly against accidental punctures. In addition, in the case of a sealing plate or similar sealing element, the sealing areas or edges are protected and therefore subjected to little or no stress. This further contributes to longevity and improves the protection of contents inside the container, such as dairy products.

[0016] The outer part is particularly, but not exclusively, suitable for wrapping reusable containers, especially reusable plastic containers or cups, or reusable metal containers or the like. After being separated from the wrapped container as required for its use, the outer part can be recycled in a largely sorted manner, while the container itself can undergo a reuse process.

[0017] Furthermore, the fold line or the fold area above it can extend over a large part or the entire length of the second end face. This has the advantage that a comparatively large area, or even the entire circumference, of the open end of the container can be covered and protected by the fold. Alternatively, the fold line may only extend over part of the length of the first end face, excluding, for example, the edge zone at the end sections in the overlap area.

[0018] The height of the fold area between the fold line and the second end face can be relatively small, so that the folded area only covers part of the open end or a closure element. However, the height can also be so great that it covers a large part of the open end or a closure element, or even the entire open end or closure element. Furthermore, the height of the fold area can be constant or vary along its length.

[0019] Furthermore, the outer part may be designed to include or be made of a cellulose fiber-containing material. This can increase recyclability and reusability.

[0020] Alternatively or additionally, the outer part may also consist of plastics, composite materials, or similar materials. Cellulose fiber-containing materials with a metallized surface or layer and / or a painted surface are also conceivable. This could, for example, improve foldability and / or allow the outer part to be used as a sealing strip. It is also possible for the outer part to be a metal foil, particularly if it serves both to encase the container and as a closure element, especially as a sealing strip, to seal the open end of the container.

[0021] Another advantageous design is one in which the folded area, when folded radially to the longitudinal axis, exhibits numerous folds, meaning it is repeatedly crimped, hemmed, or fanned. This allows for a visually appealing result. Furthermore, the material of the cut piece is reinforced or doubled in the fold area, thus further contributing to increased stability and improved durability.

[0022] Furthermore, the folding area may be formed with a multitude of additional fold lines. These additional fold lines are not parallel to the longitudinal axis of the outer part's surface when unfolded, and when folded radially to the longitudinal axis, they promote the formation of folds. This can lead to particularly regular fold formation during folding or crimping. This contributes to a visually appealing appearance and also facilitates folding. Moreover, such folds can be more durable and therefore of higher quality because they are less prone to self-unfolding.

[0023] The additional fold lines can be formed in the outer part before it is used to wrap a container. However, it is also possible that the additional fold lines are created by an assembly machine, such as a crimping machine.

[0024] According to further training, the fold line and / or subsequent fold lines may be material weakening lines, particularly perforations or die-cuts. Grooves, ribs, or indentations are also conceivable. This can further facilitate wrinkling and prevent or reduce spontaneous unfolding.

[0025] It is also conceivable that a predetermined separation area is provided in the outer part's outer shell, particularly in the overlap area or near the overlap area, which predetermined separation area extends in one direction from the first end face to the second end face or from the first end face to the fold line.

[0026] This has the advantage that providing a predetermined separation zone facilitates the separation of the outer part from the container. It may be sufficient if the predetermined separation zone does not extend over the entire longitudinal extent or height of the outer part's shell, but only from the lower first end face towards the fold line.

[0027] Design separation zones are generally known to experts in many forms. The term "projection" is also commonly used. For example, a design separation zone like the one disclosed in WO 2020 / 245148 A1 by the applicant of the same name is conceivable. It is also conceivable that the overlap area of ​​the end sections of the outer part could also be the design separation zone. For this purpose, the overlap area could, for example, be designed as a releasable adhesive bond between the overlapping end sections.

[0028] It is also conceivable that the fold line is circular in shape. This is at least the case when the outer part is not yet wrapped into a sheath, or when it is cut to size.

[0029] Furthermore, the first and / or second end face can be shaped like a circular arc, and / or they can be shaped like a wave or sinusoidal curve. This allows for an attractive and customizable appearance. This applies, of course, to the outer part in its cut state, i.e., before it is wound into a sheath or cuff. Once the outer part is wound into a sheath or cuff, the first and second end faces are advantageously arranged parallel, or at least substantially parallel, to each other. It has also proven advantageous for wave- or sinusoidal end faces to essentially follow a circular arc shape, or the annular segment-shaped basic form of the outer part. A certain degree of concentricity in the design has proven beneficial.

[0030] Furthermore, the folding area may have a tab, or be designed as a tab, which a user can grasp to open or separate the outer part from an inner cup. The tab can thus form a predetermined separation area or be part of one. It is also possible for a tab to be dimensioned such that, when folded, it can cover all or a large portion of the open end or a closure element. Another possibility is the formation of two opposing tabs when wound, which, when folded, can engage with each other, be coupled together, or be fixed in place, thus forming a closure element.

[0031] The invention also relates to a combination packaging container comprising: a container, in particular a cup-shaped container, wherein the container has a container shell having an open end and an end closed with a bottom; an outer part, in particular an outer part according to one of the claims, which encloses the container, wherein the outer part is formed from a blank, in particular from a blank according to one of the claims, which blank has a substantially annular segment-shaped basic form, which blank has a first end section and a second end section, wherein the blank is wound to form a shell and the first end section and the second end section are coupled to each other in an overlap area, wherein the outer part further has a first end face and a second end face and the first end face and the second end face are spaced apart from each other,wherein the outer part has a longitudinal extension in one direction from the first end face to the second end face, a closure element which closure element releasably closes the open end of the container. It is provided that the shell of the outer part has a fold line and a fold area, wherein the fold line is concentric to the shell of the outer part with respect to a longitudinal axis of the shell of the outer part, and wherein the fold area, when viewed in its unfolded state, is arranged in its longitudinal direction between the fold line and the second end face, and wherein the fold area projects beyond the open end of the container in the axial direction, and wherein the fold area is folded inwards along the fold line in the radial direction to the longitudinal axis of the shell of the outer part, in particular fanned, crimped or hemmed.so that the open end and / or an area of ​​the closure element is partially or completely closed or covered by the folding area.

[0032] The combination packaging container according to the invention, with a folded or crimped fold area of ​​the outer part, offers the surprising advantage that the fold area and the fold line ensure that the outer part and the container wrapped with the outer part, particularly the cup-shaped container, must be separated to allow access to the contents contained within. This allows for improved separation and recycling in a particularly simple and visually appealing manner. Furthermore, the outer part can form a high-quality and attractive outer packaging for the container, and can also serve as proof of authenticity, thus acting as "tamper evident."Furthermore, the folded edge protects a sealing element, such as a sealing plate or a thin lid, thus increasing its stability and durability, particularly against accidental punctures. In addition, in the case of a sealing plate or similar sealing element, the sealing areas or edges are protected and therefore subjected to little or no stress. This further contributes to longevity and improves the protection of contents inside the container, such as dairy products.

[0033] The outer part is particularly, but not exclusively, suitable for wrapping reusable containers, especially reusable plastic containers or plastic cups. After being separated from the wrapped container as required for its use, the outer part can be largely sorted and recycled, while the container itself can undergo a reuse process. It is also conceivable that the outer part could be partially fixed to the wrap, particularly by gluing.

[0034] By partially or completely covering the open end and / or a portion of the closure element with the folded section, it is ensured that a user only gains access to the container contents after removing the outer part and then—as is customary—removing the closure element. Because this separation is inherently necessary due to the design, it simultaneously guarantees that the outer part can be recycled separately, and furthermore, the user is guaranteed the ability to open the container initially.

[0035] This design ensures that the outer part contributes to the protection of the closure element and prevents unwanted premature detachment or damage to the closure element. Furthermore, it can also be advantageous if the folding of the folding area additionally prevents or limits radial movement of the outer part relative to the container.

[0036] The sealing element can be a foil, such as a sealing sheet or sealing foil. Alternatively or additionally, the sealing element can also be designed as a lid, for example, a screw cap or a hinged lid. A snap-on or impact-type lid is also conceivable. Depending on the design of the sealing element, the open end can be formed with a sealing rim, a flange, a collar, a perforated edge, a thread, etc. In any case, it can be advantageous if a portion of the open end extends radially beyond the container wall and also beyond the outer surface, relative to the longitudinal axis or the conical axis.

[0037] According to an advantageous embodiment, the closure element with the folded section can be covered in such a way that removal of the closure element from the open end is only possible after unfolding the folded section or removing the outer part from the container. This has the advantage of enabling tamper-evident verification. Furthermore, it ensures the separation of the materials.

[0038] It is also conceivable that the closure element is connected to the outer part and that the closure element is designed in such a way that it can be removed simultaneously with the removal of the outer part from the container. This has the advantage of simplifying use, as both the outer part and the closure element can be removed in a single step. Especially since the outer part has a folding area, this folding area, or possibly an additional one at the folding area, can be connected or glued to the closure element, particularly with a sealing film, so that the sealing film can be removed together with the folding area. Furthermore, this can also facilitate recycling. This is especially true if the closure element and the outer part remain connected even after removal.if the locking element and the outer part are made at least substantially from materials that can be recycled together.

[0039] Furthermore, the outer shell may extend over a portion of the container shell, preferably between one-quarter and two-thirds of its length. This allows part of the container height to be covered by the outer shell, while the portion of the container shell facing the bottom remains uncovered and thus visible to an observer. In particular, the outer shell may extend over a portion of the container shell when viewed longitudinally. This results in a portion of the container height being covered by the outer shell. This offers the advantage of improved sustainability by saving material. Moreover, the visual appearance is appealing and distinctive.

[0040] It is also possible that the outer layer extends over the entire container shell, thus completely encasing it. Furthermore, it is also possible that the outer layer extends over the closed end, i.e., the container bottom, and covers it completely or partially. In this case, folds, crimps, or crimped areas may also be present on the container bottom.

[0041] According to another interpretation, the container could be reusable, particularly a reusable container made of plastic. This offers the advantage of further improving the sustainability of the combined packaging container. It can also be advantageous if the plastic material is recycled or at least partially made from recycled materials. However, the container could also be single-use.

[0042] Furthermore, the folding area may have a tab that a user can grasp to open or separate the outer part from an inner cup. In this way, the tab can form a designated separation area or be part of a designated separation area.

[0043] According to an advantageous embodiment, the container shell and the outer shell can each be substantially frustoconical and arranged around a common conical axis, and a first angle between the container shell and the conical axis is equal to or smaller than a second angle between the outer shell and the conical axis. This has the advantage of enabling a good connection or coupling between the outer shell and the container.

[0044] Depending on the specific shape of the container or the outer part, the longitudinal axis and the conical axis may be identical or congruent.

[0045] In particular, it can be advantageous if the open end and / or the closure element has a collar projecting beyond the container wall in the radial direction to the cone axis (i.e., at 90° to the cone axis when considering the container), wherein a third angle is formed between the cone axis and an imaginary line of intersection, which imaginary line of intersection extends from an outermost point of the collar to the cone axis and intersects the first end face. Here, the third angle is equal to or at least approximately equal to the second angle. An outermost point of the collar is the point furthest away from the longitudinal axis or the cone axis when viewed in the radial direction. Naturally, in a symmetrical design, several such outermost points may be formed on the collar, in particular a circumferential outermost circle on which the outermost points lie.This has the advantage of enabling a good connection or coupling between the outer part and the container.

[0046] Depending on the type and design of the container and the closure element, it may be advantageous if the collar is designed with a flange, a thread or a crimped edge.

[0047] The invention also relates to a method for manufacturing a combination packaging container, in particular a combination packaging container according to one of the claims, comprising the following method steps: Providing a container, in particular a cup-shaped container, wherein the container has a container shell having an open end and an end closed with a bottom; filling the container with a filling material; closing the open end of the container with a releasable closure element; providing a blank, in particular a blank according to the claims, which blank has a substantially annular segment-shaped basic form, wherein the blank has a first end section and a second end section, wherein the blank further has a first end face and a second end face, and wherein the first end face and the second end face are spaced apart from each other, wherein the blank has a longitudinal extension in a direction starting from the first end face to the second end face, and wherein the blank has a fold line and a fold area.wherein the fold line is concentric with respect to a circular center point of the annular segment-shaped basic form, and wherein the fold area, viewed in its longitudinal extension, is arranged between the fold line and the second end face, and wherein the fold area is foldable along the fold line, forming an outer part from the blank, in particular an outer part according to one of the claims, by wrapping the container with the blank or forming an outer part from the blank, in particular an outer part according to one of the claims, and axially sliding the outer part onto the container, such that the fold line is arranged concentrically to the outer part's surface with respect to a longitudinal axis of the outer part's surface, wherein the first end section and the second end section are coupled together in an overlap area, the first end face facing the bottom and the second end face facing the open end of the container,Folding the fold area along the fold line in a radial direction to the longitudinal axis of the outer part's surface, so that the open end and / or an area of ​​the closure element is partially or completely covered or closed by the fold area.

[0048] Such folding can also be referred to as crimping. The inventive method for manufacturing a combination packaging container offers the surprising advantage that – particularly when the method is carried out in the described sequence – a combination packaging container as described above, with the advantages described above, can be manufactured efficiently.

[0049] It is also conceivable that the still empty and unsealed container is first encased with the outer parts, with the folding sections remaining unfolded, so that several such combination containers can be stacked inside each other. In the further process, individual containers can be picked up from the stack and filled, closed (in particular sealed), and the folding section can be folded.

[0050] In principle, an alternative sequence of the described process steps would also be conceivable. For example, the container could first be encased with the outer part, or the outer part could be attached to the container, and the container could only be filled and sealed afterwards. In this case, it is necessary that the open end of the container is designed in such a way that a closure can still be attached even with the outer part mounted and the folding section not yet folded.

[0051] Forming an outer part from the cut-out by wrapping it around the container can be done by directly wrapping the material onto the container. For this purpose, the container may be mounted on a winding mandrel.

[0052] It is also conceivable that, instead of directly wrapping the container with the outer part, the outer part is formed by axially sliding it onto the container, with the first end face facing the bottom and the second end face facing the open end of the inner container. Specifically, the forming of the outer part and the joining of the first and second end sections in the overlap area can be carried out in a separate process step, and the formed outer part can then be slid onto the inner container from below in a further process step by axial displacement.

[0053] In this process, the container may be fixed and / or positioned in the area of ​​the bottom of the container by coupling a coupling element with an alignment means, in particular with a groove or with a protrusion, before being wrapped with the outer part or before the outer part is axially slid on.

[0054] The invention further relates to a method for opening a combination packaging container, in particular a combination packaging container according to one of the claims, comprising a container, in particular a cup-shaped container, wherein the container has a container shell having an open end, which open end is closed with a closure element, and which has an end closed with a bottom, and comprising an outer part, in particular an outer part according to one of the claims, which outer part encloses the container, wherein the outer part is formed from a blank, in particular a blank according to the claims. The blank has a substantially annular segment-shaped basic form and comprises a first end section and a second end section, wherein the blank is wound into a shell and the first end section and the second end section are coupled to each other in an overlap area.wherein the outer part further comprises a first end face and a second end face, and the first end face and the second end face are spaced apart from each other, wherein the outer part has a longitudinal extension in a direction extending from the first end face to the second end face, and wherein the outer part's surface has a fold line and a fold area, the fold line being concentric to the outer part's surface with respect to a longitudinal axis of the outer part's surface, and wherein the fold area, viewed longitudinally, is located between the fold line and the second end face, and wherein the fold area is folded radially along the fold line to the longitudinal axis of the outer part's surface such that the open end and / or a region of the closure element is partially or completely covered by the fold area, and wherein a predetermined separation area is provided in the outer part's surface.which target separation area extends in one direction from the first end face to the second end face or from the first end face to the fold line.

[0055] The procedure includes the following steps: Separating the outer part from the container by opening the designated separation area and removing the sealing element from the open end of the container.

[0056] Separating the outer part from the container by opening the designated separation area can be complete or partial. In the case of partial separation, the outer part or a portion thereof is separated in such a way that the closure element can be removed afterward.

[0057] The inventive method for opening a combination packaging container offers the surprising advantage that the user is shown, or rather guaranteed, that they are performing the initial opening of the originally sealed container. Furthermore, the user is essentially compelled to detach the outer part from the container, thus encouraging recycling, as they would otherwise have no access to the contents. This therefore makes a significant contribution to sustainability, particularly when the opening process is carried out in the described sequence.

[0058] To better understand the invention, it is explained in more detail with reference to the following figures.

[0059] They each show, in a highly simplified, schematic representation: Fig. 1 shows a cut-out; Fig. 2 shows a combination packaging container with a container and an outer part, in view, before folding the folding area, partially cut away; Fig. 3 shows the combination packaging container on Fig. 2 with a container and an outer part, in view, after folding the folding area, partially cut away; Fig. 4 another combination packaging container in three-dimensional representation.

[0060] It should be noted at the outset that in the differently described embodiments, identical parts are provided with the same reference numerals or component designations, and the disclosures contained in the entire description can be applied analogously to identical parts with the same reference numerals or component designations. Furthermore, the positional designations chosen in the description, such as top, bottom, side, etc., refer to the figure directly described and illustrated, and these positional designations must be applied analogously to the new position if the position changes.

[0061] The term "in particular" is understood below to mean that it may refer to a possible more specific design or further specification of an object or a process step, but does not necessarily have to represent a mandatory, preferred embodiment of the same or a mandatory procedure.

[0062] In their present usage, the terms "comprehensive", "indicates", "includes", "includes", "contains", "containing" and any variations thereof are intended to cover a non-exclusive inclusion.

[0063] Another term that can be used is "optional." This means that this process step or plant component is generally available, but can be used depending on the operating conditions; however, this is not mandatory.

[0064] The figures are described below largely in a single overview to avoid unnecessary repetition. Specific features and differences between the figures and examples are discussed in more detail.

[0065] In the Fig. 1An example of a variety of possible different shapes is a flat cutout 13, whereby the cutout 13 can be wrapped to form a cuff-shaped outer part 12 or a coat.

[0066] In particular, it is provided that the flat blank 13 has a substantially circular segment-shaped base, wherein the blank 13 comprises a first end section 14 and a second end section 15. The two end sections 14, 15 are preferably each aligned along an imaginary line to the center of the circular segment-shaped base. The blank 13 can be wound into a sheath. The first end section 14 and the second end section 15 can be coupled to each other in an overlap area 16. By winding the blank, the end sections 14, 15 can be joined to each other in a simplified representation of the overlap area 16. This can be achieved by means of a so-called overlap seam, by which the first end section 14 and the second end section 15 adhere to each other, for example, by means of an adhesive layer.The first end section 14 of the blank 13 terminates with a first longitudinal edge 17, and the second end section 15 terminates with a second longitudinal edge 18. When considering the blank 13 in its flat state or its unwound state, the two longitudinal edges 17, 18 can preferably each be aligned along an imaginary line to the center of the circular segment of the annular base. Furthermore, the blank 13 can have a longitudinal edge length 33 in the area of ​​the first end section 14, particularly at the first longitudinal edge 17. Any reduction in the actual longitudinal edge length due to rounding or chamfering is disregarded here when considering the longitudinal edge length 33.

[0067] In the overlap area 16 and in the wound state, the two longitudinal edges 17, 18 run approximately parallel to each other, with the overlap area 16, with an overlap width, forming between them when viewed in the circumferential direction of the sheath. 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. It goes without saying that an arrangement is also conceivable in which the first end section 14 is folded over the second end section 15 on the outside.

[0068] The blank 13, or an outer part 12 formed from the blank 13, further comprises a first end face 19 and a second end face 20, wherein the first end face 19 and the second end face 20 are spaced apart from each other, and wherein the blank 13 or the outer part 12 has a longitudinal extension 22 in a direction extending from the first end face 19 to the second end face 20. The end faces are preferably substantially concentric with respect to the center of the circular segment of the basic annular shape. The two end faces 19, 20, which are spaced apart from each other, define a height 21 of the outer part 12 when viewed in its erect state. In particular, if the outer part 12 is conical, the height 21, when viewed in axial section, geometrically corresponds to the height of the cone.In particular, if the outer part 12 is conical, its longitudinal extent 22, viewed in axial section, is geometrically the length of the generatrix. A substantially circular segment-shaped cut 13, when wound into a shell, inevitably results in a conical shell. Therefore, the maximum longitudinal extent 22 of a conical outer part 12 is generally greater than the shell's height 21. The previously described longitudinal axis 8 can also define the common longitudinal axis for the outer part 12, especially when the outer part 12 is in its assembled position on the container 2. The shell's height 21 is usually slightly less than the container height 9 of the container 2 in the same spatial direction—namely, along the longitudinal axis 8.

[0069] The blank 13 has a fold line 23 and a fold area 24, wherein the fold line 23 - in an unwound or in a flat state - is concentric with respect to a circular center point of the annular segment-shaped basic form, and the fold area 24 is arranged in longitudinal extension 22 between the fold line 23 and the second end face 20, and is foldable along the fold line 23.

[0070] Similarly, the outer part 12 has a fold line 23 and a fold area 24, wherein the fold line 23 is formed concentrically to the outer part 12 with respect to a longitudinal axis 8 of the outer part 12, and wherein the fold area 24 is arranged in longitudinal extension 22 between the fold line 23 and the second end face 20, and wherein the fold area 24 is foldable along the fold line 23 in a radial direction to the longitudinal axis 8 of the outer part 12, so that the open end 5 can be closed at least partially by the fold area 24.

[0071] In the exemplary embodiment of a flat-surface cutout 13 or of a non-wound outer part 12 according to Fig. 1 It has been shown that the folding area 24 represents a quasi-extension of the hull, with the folding area 24, as in the Fig. 2shown, projecting axially beyond the open end 5 or the flange 6 or collar 31 of the container 2. In its folded, in particular fan-shaped, flared or crimped state according to Fig. 3 The folding area 24 is folded or crimped or hemmed inwards and covers the open end 5, or a closure element 29, at least partially.

[0072] The fold line 23 may extend over a large part of the length 25 or the entire length 25 of the second end face 20. In the illustrated embodiment, the fold line 23 extends over the entire length 25 of the second end face 20. Dashed lines are used to indicate the Fig. 1Furthermore, a variant is sketched in which the fold line 23 does not extend over the entire length 25 of the second end face 20, but in which the second end face 20 is not formed with the fold area 24 in the area bordering the end sections 14, 15, or the fold line 23 ends at least on one side in the overlap area 16. This is, of course, representative of a multitude of conceivable designs.

[0073] The outer part 12 may comprise or be formed from a cellulose fiber-containing material.

[0074] It is also possible that the folded area 24, in its radially folded state relative to the longitudinal axis 8, particularly in a fan-shaped folded, hemmed, or crimped state, has a plurality of folds 26. This is particularly true in the Fig. 3 and 4 shown.

[0075] It is also possible that the folding area is 24, as in the Fig. 1shown, is formed with a plurality of further fold lines 27, wherein the further fold lines 27 in an unfolded state are not arranged parallel with respect to the longitudinal axis 8 of the outer part 12 and wherein the further fold lines 27 in their radially folded state to the longitudinal axis 8, in particular fan-shaped folded, crimped or crimped state, promote the formation of the folds 26 or crimping.

[0076] It is also possible that fold line 23 and / or the other fold lines 27 are material weakening lines, in particular perforations or punchings.

[0077] Furthermore, the first end face 19 and / or the second end face 20 may be circular arcs, and / or the first end face 19 and / or the second end face 20 may be wavy or sinusoidal. The fold line 23 may also be circular arcs. The first end face 19 and the second end face 20 can be as shown in the Fig. 1 The first end face 19 is shown to be circular arc-shaped. However, it is also possible that the first end face 19 is circular arc-shaped, and that the second end face 20 is wave- or sinusoidal. It goes without saying that this configuration is merely an example of various conceivable shapes. In any case, the first end face 19 and the second end face 20 essentially follow a circular arc shape and are essentially concentric with respect to a circular center point of the annular segment-shaped basic form.

[0078] It may be that in the cut 13, or in the outer part 12, particularly in or near the overlap area 16, a predetermined separation area 28 is provided, which predetermined separation area 28 extends in one direction from the first end face 19 to the second end face 20 or from the first end face 19 to the fold line 23. Fig. 1 and 4 The designated separation area 28 is designed as a so-called elevation, for example in accordance with WO 2020 / 245148 A1 of the applicant of the same name. In the Fig. 2 and 3 A separation zone 28 is provided in the overlap zone 16 of the end sections 14, 15 or the longitudinal edges 17, 18. For this purpose, the overlap zone 16 can, for example, be designed as a detachable adhesive connection.

[0079] It is also possible that the folding area 24 has a tab 32, which tab 32 is accessible to a user for opening or separating the outer part from an inner cup. In the Fig. 1 A possible embodiment of a tab 32 is shown by means of dashed lines.

[0080] In the Fig. 2 and 3 Figure 1 shows an exemplary embodiment of a combination packaging container 1, representing a multitude of possible different shapes, wherein the combination packaging containers 1 are particularly cup- or bowl-shaped. The combination packaging container 1 is in the Fig. 2 and 3The diagram shows a section partially cut through the longitudinal axis 8. The combination packaging container 1 comprises a container 2, which is particularly cup- or bowl-shaped, with a base 3 and a container shell 4. The container 2 also has an open end 5 on the side facing away from the base 3. Furthermore, a flange 6 projecting outwards beyond the container shell 4 may be provided in the area of ​​its open end 5. The base 3 forms a closed end 7 for the container shell 4. The container 2 has a substantially conical or frustoconical basic shape. When viewing the combination packaging container 1 in the frontal view shown, the combination packaging container 1 has a total height 10, which extends from the base 3 to the highest point of the second end face 20 of the outer part 12. The total height 10 is therefore greater than the container height 9 and also greater than the overall height 21 of the outer part 12.

[0081] The container 2 is preferably formed by a component produced using a deep-drawing process, which can be manufactured quickly and, above all, with a short cycle time. The deep-drawing process is well known and therefore will not be described in detail. The deep-drawing process is particularly suitable for producing the container 2 with a sufficient wall thickness from a formable layer of a deformable material using a deep-drawing tool, ensuring leak-tightness during storage, use, and disposal. This manufacturing process allows for relatively thin wall thicknesses of the inner container 2. However, the container 2 can also be formed using other manufacturing methods, such as injection molding.

[0082] Due to the cup- or bowl-shaped design of the container 2, a longitudinal axis 8 extends axially between the open end 5 and the end 7 closed by the bottom 3. In the case of a symmetrical design, this axis can also represent a central axis. A closure element 29, for example a sealing plate, can be positioned or connected to the flange 6. In this case, the flange 6 forms a sealing flange.

[0083] In the axial direction, and thus in the direction of the longitudinal axis 8, the container 2 has a height 9 between its open end 5, in particular the flange 6, and the bottom 3, which determines the capacity of the container 2 depending on its cross-sectional dimensions. The container height 9, in conjunction with the cross-sectional dimensions, thus defines the capacity of the container 2.

[0084] The container shell 4 is understood to be that section of the container 2 which extends in a predominantly axial direction between the open end 5, in particular the flange 6, and the bottom 3. Preferably, the container 2 with its container shell 4 is designed such that the shell tapers conically from the open end 5 towards the bottom 3, i.e., is essentially frustoconical. In this design, the longitudinal axis 8 corresponds to the cone axis 34.

[0085] The combination packaging container 1 further comprises an outer part 12, which is designed in a cuff-like or mantle-like form and surrounds the container 2 in the area of ​​its container mantle 4 at least partially or partially.

[0086] The cuff-shaped outer part 12 is preferably made of a cellulose material, such as cardboard, with sufficient strength to absorb and transmit compressive forces, particularly those acting axially, and is wound from a flat blank 13 into a sheath. The blank 13 is usually printed in its undeformed, flat state and optionally provided with an additional coating. Of course, it is also conceivable that the blank 13 is made of multiple parts. A cellulose material is usually used as the material for the blank 13, although this can also be cardboard or heavy paper produced by recycling. If a layer of the outer part 12 is made of a recycled material, an additional layer of a higher-quality paper can be arranged on or bonded to at least one of the surfaces.This additional layer ensures flawless printing for the production of decorations, lettering, and product information.

[0087] The cuff-like or mantle-like outer part 12 leads to an additional reinforcement or stiffening effect of the 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.

[0088] It may 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 if 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 shell 4 of the combination packaging container 1.

[0089] Container 2 may preferably be a reusable container, which in particular is made of or comprises a plastic material or a recycled plastic material.

[0090] It is also possible that the container 2 has an alignment means, in particular a groove or a protrusion, in the area of ​​its bottom 3, which is designed for fixing and / or positioning the container 2.

[0091] In the Fig. 2 and 3 An exemplary embodiment of a combination packaging container 1 is shown. In the Fig. 4 Another embodiment of a combination packaging container 1 is shown. The combination packaging containers 1 comprise: a container 2, in particular a cup-shaped container, wherein the container 2 has a container shell 4 having an open end 5 and an end 7 closed with a bottom 3; an outer part 12, in particular an outer part 12 according to the above description, which encloses the container 2, wherein the outer part 12 is formed from a blank 13, in particular a blank 13 according to the above description, which blank 13 has a substantially annular segment-shaped basic form, which blank 13 has a first end section 14 and a second end section 15, wherein the blank 13 is wound into a shell and the first end section 14 and the second end section 15 are coupled to each other in an overlap area 16, wherein the outer part 12 further has a first end face 19 and a second end face 20 and the first end face 19 and the second end face 20 are spaced apart from each other,wherein the outer part 12 has a longitudinal extension 22 in a direction extending from the first end face 19 to the second end face 20, a closing element 29 which releasably closes the open end 5 of the container 2.

[0092] The outer part 12 has a fold line 23 and a fold area 24, wherein the fold line 23 is concentric to the outer part 12 with respect to a longitudinal axis 8 of the outer part 12, and wherein the fold area 24 is arranged between the fold line 23 and the second end face 20 when viewed in its longitudinal extent 22, and wherein the fold area 24 is folded, in particular fanned, hemmed, or crimped, along the fold line 23 in a radial direction to the longitudinal axis 8 of the outer part 12, such that the open end 5 and / or an area 30 of the closure element 29 is partially or completely covered by the fold area 24. Fig. 2The combination packaging container 1 is encased with the outer part 12, but the folding area 24 is not yet folded, and the open end 5 and / or the area 30 of the closure element 29 protrudes partially or completely. In the Fig. 3 The combination packaging container 1 is encased with the outer part 12, and the folding area 24 is folded or crimped along the folding line 23, wherein the folding area 24 still extends at least slightly beyond the open end 5 of the container 2 in the axial direction, so that the open end 5 and / or an area 30 of the closure element 29 is partially or completely covered by the folding area 24.

[0093] It may be that the closure element 29 is covered by the folded, in particular fan-shaped, crimped or rolled folding area 24 in such a way that removal of the closure element 29 from the open end 5 is only possible after unfolding the folding area 24 or after removing the outer part 12 from the container 2.

[0094] Furthermore, the closure element 29 may be connected to the outer part 12, and the closure element 29 may be designed such that it can be removed simultaneously with the removal of the outer part 12 from the container 2. For example, the closure element 29 may be designed as a sealing plate, which may be glued or otherwise connected to the outer part 12, so that the sealing plate is removed along with the outer part 12 when it is detached.

[0095] Furthermore, the outer shell 12 may extend over a portion of the container shell 4, preferably between one quarter and two-thirds of the container shell 4. In the Fig. 2 and 3 , as well as in the three-dimensional representations of combination packaging containers 1 in the Fig. 4 The outer parts 12 with different slant heights or different maximum longitudinal extents 22 are shown. Consequently, the parts of the container 2 visible to an observer are of different sizes.

[0096] It is also conceivable that container 2 is a reusable container, in particular a reusable container comprising a plastic material.

[0097] The container shell 4 of container 2 and the shell of the outer part 12 can be arranged as shown in the Figs. 2 to 4 depicted as being essentially frustoconical and arranged around a common conical axis 34. In the Fig. 2 and 3The partial axial section shown is sketched to indicate that a first angle 35 between the container shell 4 of the container 2 and the cone axis 34 may be smaller than a second angle 36 between the shell of the outer part 12 and the cone axis 34.

[0098] Furthermore, in the Fig. 2 and 3 The partial axial section shown illustrates that the open end 5 and the closure element 29 have a collar 31 projecting radially to the cone axis 34 over the container shell 4 of the container 2, wherein a third angle 37 is formed between the cone axis 34 and an imaginary section line 38, which imaginary section line 38 extends from a radially outermost point of the collar 31 to the cone axis 34 and intersects the first end face 19, wherein the third angle 37 is equal to or approximately equal to the second angle 36.

[0099] The Fig. 4Figure 1 shows a three-dimensional view of an exemplary embodiment of a combination packaging container 1, where the example is to be understood as representative of a multitude of conceivable designs. Reference is made to the preceding descriptive sections, and to avoid unnecessary repetition, special features of the illustrated variants are discussed below.

The open end 5 or the sealing element 29 is partially covered by the folded or crimped fold area 24.

[0102] The container 2 can be fixed and / or positioned in the area of ​​the bottom 3 of the container 2 by coupling a coupling element with an alignment means, in particular with a groove or with a protrusion, before wrapping it with the outer part 12 or before axially sliding the outer part 12 on.
