  • the invention further relates to a method for producing a combination packaging container, and a method for opening a combination packaging container.
  • Recycling should enable the pure separation of different materials to improve recycling quality.
  • the pure separation of different materials 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.
  • used products and product packaging should be processed into reusable products and product packaging in a simple and sustainable manner.
  • the WO 2020/245148 A1 describes a sleeve-shaped outer part formed from a blank, wherein the blank is wound into a jacket and the end sections of which are connected to one another in an overlapping area.
  • the sleeve-shaped outer part together with a cup-shaped inner container, forms a combination packaging container.
  • a predetermined separation area comprises an actuating means with a detection section for separating separation sections located on both sides. In a combination packaging container designed in this way, the predetermined separation area is intended to be separated after use of the container, which is why separation of the components and subsequent recycling or reuse is not guaranteed.
  • 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 sleeve-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 closability and durability of container closures, in particular of reusable containers.
  • the term “container” encompasses a variety of conceivable shapes, configurations, and intended uses. It can be a cup-shaped container, but also a tub-shaped, bowl-shaped, or bottle-shaped container.

  • the blank according to the invention has the surprising advantage that the folding area and the folding line can be used to separate the blank and a container, in particular a cup-shaped container, wrapped with the blank. must be removed to allow access to the contents contained in the container. This ensures improved separation and recycling in a particularly simple and visually appealing way.
  • the blank can form high-quality and attractive outer packaging for a container, whereby the blank can also serve as proof of tamper-evident evidence and is thus considered “tamper-evident.”
  • the folded fold area contributes to the protection of a closure element, such as a sealing plate or a thin lid, thereby increasing its stability and durability, particularly with regard to accidental puncture.
  • sealing areas or sealing edges are protected and thus subject to little or no stress. This further contributes to the longevity and improves the protection of the contents contained in the container, for example, pasty or liquid contents such as dairy products, but also powdered contents or bulk materials of any kind.
  • the blank is particularly, but not exclusively, suitable for wrapping reusable containers, especially reusable plastic containers or plastic cups. After the required separation from the wrapped container for use, the blank can be recycled in a largely pure state, while the container itself can be reused.
  • the blank can be a part cut from a sheet or a sheet-like element, for example, from paper, cardboard, or even a thin plastic sheet.
  • Composite materials made of paper, cardboard, and/or plastic, or even with a thin metal layer, are also conceivable.
  • Aluminum-containing foils are also conceivable.
  • the invention also relates to an outer part for encasing a container, in particular a cup-shaped container, which has a container shell which has an open end and an end closed by 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 circular ring-segment-shaped basic shape, which blank has a first end section and a second end section, wherein the blank is formed into a shell is wound and the first end portion and the second end portion are coupled to one another in an overlap region, 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 one another, wherein the outer part has a longitudinal extension in a direction starting from the first end face to the second end face.

  • Folding here means, in particular, crimping, flanging, or fan-shaped or fan-like folding.
  • the fold line and/or the fold area may already be pre-folded, pre-crimped or pre-flanged before the outer part is wrapped around a container, or the fold line and/or the fold area may only be folded, crimped or flanged after the outer part has been wrapped around a container.
  • the outer part according to the invention offers the surprising advantage that, thanks to the folding area and the folding line, the outer part and a container, particularly a cup-shaped container, wrapped with the outer part must be separated from each other to allow access to a product contained in the container.
  • the outer part can form a high-quality and attractive outer packaging for a container, whereby the outer part can also fulfill a function as proof of originality and is thus considered "tamper evident.”
  • the folded folding area contributes to the protection of a closure element, for example, a sealing plate or a thin lid, thus increasing its stability and durability, particularly with regard to accidental puncture.
  • a sealing plate or a similar closure element the sealing areas or sealing edges protected and thus subjected to little or no wear. This further contributes to its longevity and improves the protection of the contents of the container, such as dairy products.
  • the outer part is particularly, but not exclusively, suitable for wrapping reusable containers, in particular reusable plastic containers or plastic cups or reusable metal containers or the like. After the separation from the wrapped container required for use, the outer part can be recycled in a largely pure state, while the container can be reused.
  • the fold line or the folding area above it extends over a large part of the length or the entire length of the second end face. This has the advantage that a comparatively large area or even the entire peripheral area of the open end of the container can be covered and protected by the fold. It can also be the case that the fold line extends only over part of the length of the first end face, for example, excluding the edge zone at the end sections in the overlapping area.
  • the height of the fold area between the fold line and the second end face can be comparatively small, so that the folded fold area can only cover part of the open end or a closure element. However, the height can also be so large that it can cover a large part of the open end or a closure element, or the entire open end or the entire closure element.
  • the height of the fold area can also be constant, but can also vary along its length.
  • the outer part may comprise a cellulose fiber-containing material or be formed from a cellulose fiber-containing material. This can increase recyclability and reusability.
  • the outer part may also comprise plastics, composite materials, or the like.
  • Cellulose fiber-containing materials with a metallized surface, or a metallized layer, and/or with a lacquered surface are also conceivable. This may, for example, improve foldability and/or allow the outer part to be used as a sealing plate.
  • the outer part may comprise a Metal foil. This is especially true when the outer part serves both to enclose the container and as a closure element, particularly as a sealing plate, for sealing the open end of the container.
  • Another advantageous feature is a design in which the folding area, when folded radially to the longitudinal axis, has a multitude of folds, i.e., it is crimped, flanged, or fan-folded multiple times. This can achieve a visually appealing result. Furthermore, the material of the blank is reinforced, or doubled, in the fold area, thus further contributing to increased stability and improved longevity.
  • the folding area can be formed with a plurality of further folding lines, wherein the further folding lines are not arranged parallel to the longitudinal axis of the casing of the outer part in an unfolded state, and wherein the further folding lines promote the formation of the folds when folded radially to the longitudinal axis.
  • This can promote particularly regular folding during folding or crimping. This further contributes to a visually appealing appearance and also facilitates folding.
  • folds can also be more durable and therefore of higher quality because they are less likely to unfold spontaneously.
  • the additional fold lines can be formed in the outer part before it is wrapped around a container.
  • the additional fold lines can also be created by an assembly system, such as a crimping machine.
  • the fold line and/or the other fold lines may be material weakening lines, in particular perforations or punchings. Grooves, ribs, or pressings are also conceivable. This can further facilitate the formation of folds and prevent or reduce spontaneous unfolding.

It has also proven advantageous for wavy or sinusoidal end faces to substantially follow a circular arc shape, or rather the basic circular ring-segment-shaped shape of the outer part. A certain concentricity of the design has proven to be expedient.
  • the folding area may have a tab or be designed as a tab, which tab is grippable by a user for opening or separating the outer part from an inner cup.

It is also conceivable, in principle, for the outer part to be fixed, in particular glued, to the casing in certain areas.
  • This design allows the outer part to contribute to protecting the closure element and prevent unwanted premature detachment or damage to the closure element. Furthermore, it can also be useful if the folding of the folding area also prevents or limits radial movement of the outer part relative to the container.
  • the closure element can be a film, for example a sealing plate or sealing film.

  • the folding region 24, in its state folded in the radial direction to the longitudinal axis 8, in particular in a fan-shaped folded, flanged or crimped state, has a plurality of folds 26. This is particularly the case in the Fig. 3 and 4 shown.
  • the folding area 24, as in the Fig. 1 shown, 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 casing of the outer part 12 and wherein the further fold lines 27 in their folded state in the radial direction to the longitudinal axis 8, in particular folded in a fan shape, flanged or crimped, promote the formation of the folds 26 or crimping.
  • first end face 19 and/or the second end face 20 may be formed in the shape of a circular arc, and/or the first end face 19 and/or the second end face 20 may be formed in the shape of a wave or sinusoid. It may also be that the fold line 23 is formed in the shape of a circular arc.
  • the first end face 19 and the second end face 20 may be formed as shown in the Fig. 1 It can also be that the first end face 19 is circularly arc-shaped and that the second end face 20 is wave-shaped or are formed in a sinusoidal curve. It goes without saying that this embodiment is merely exemplary 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 circle center of the circular ring segment-shaped basic shape.
  • FIG. 2 and 3 An embodiment of a combination packaging container 1 is shown as an example for a variety of possible different shapes, wherein the combination packaging containers 1 are in particular cup-shaped or bowl-shaped.
  • the combination packaging container 1 is in the Fig. 2 and 3 shown partially sectioned through the longitudinal axis 8.
  • the combination packaging container 1 comprises a container 2, in particular cup-shaped or bowl-shaped, with a base 3 and a container shell 4.
  • the container 2 further has an open end 5 on its side facing away from the base 3. Furthermore, in the region of its open end 5, a flange 6 projecting outwards beyond the container shell 4 can be provided.
  • the base 3 forms a closed end 7 for the container shell 4.
  • the container 2 has a substantially conical or truncated cone-shaped basic shape.
  • the combination packaging container 1 When viewing the combination packaging container 1 in the front view shown, the combination packaging container 1 has a total height 10, which extends from the base 3 up to the highest region of the second end face 20 of the outer part 12. The total height 10 is thus greater than the container height 9 and also greater than the overall height 21 of the outer part 12.
  • the container 2 is preferably formed from a component produced in a deep-drawing process, which can be manufactured quickly and, above all, in a short cycle time.
  • the deep-drawing process is sufficiently well known and will therefore not be discussed in detail.
  • the deep-drawing process is particularly suitable for producing the container 2 from a layer of a formable material to be formed using a deep-drawing tool, with a sufficient wall thickness that ensures tightness during storage, use, and even disposal.
  • This manufacturing process allows relatively thin walls of the inner container 2 to be manufactured.
  • the container 2 can also be formed using other manufacturing methods, such as an injection molding process.
  • a longitudinal axis 8 extends axially between the open end 5 and the end 7 closed by the base 3.
  • This longitudinal axis 8 can also represent a central axis if the design is symmetrical.
  • a closure element 29 for example, a sealing plate.
  • the flange 6 forms a sealing flange.
  • the container 2 In the axial direction and thus in the direction of the longitudinal axis 8, the container 2 has a container height 9 between its open end 5, in particular the flange 6, and the base 3, whereby the receiving volume of the container 2 is determined depending on the cross-sectional dimensions.
  • the container height 9 in conjunction with the cross-sectional dimensions thus defines a receiving space of the container 2.
  • the container shell 4 is understood to be that section of the container 2 which extends predominantly axially between the open end 5, in particular the flange 6, and the base 3.
  • the container 2 with its container shell 4 is designed such that it tapers conically from the open end 5 toward the base 3, i.e., is essentially frustoconical.
  • the longitudinal axis 8 corresponds to the cone axis 34.
  • the combination packaging container 1 further comprises an outer part 12 which is sleeve-shaped or jacket-shaped and surrounds the container 2 in the region of its container jacket 4 at least in sections or regions.
  • the sleeve-shaped outer part 12 is preferably formed from a cellulose material, such as cardboard, with sufficient strength with regard to the absorption and transmission of, in particular, axially acting compressive forces, and is wound from a flat blank 13 into a sleeve.
  • the blank 13 is usually printed in its undeformed, flat position and, if necessary, provided with an additional coating.
  • the material used for the blank 13 is usually a cellulose material, although this can also be cardboard or strong paper produced using a recycling process.
  • the cardboard is additionally coated or sealed with a water-repellent material in the area of the cut edges. This is particularly advantageous when the combination packaging container 1 is exposed to increased moisture ingress. 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 detaching from the container shell 4 of the combination packaging container 1.
  • the container 2 may preferably be a reusable container, which in particular is or comprises a plastic material or a recycled plastic material.
  • the jacket of the outer part 12 has a fold line 23 and a fold region 24, wherein the fold line 23 is formed concentrically to the jacket of the outer part 12 with respect to a longitudinal axis 8 of the jacket of the outer part 12, and wherein the fold region 24 is arranged between the fold line 23 and the second end face 20 as viewed in the longitudinal extent 22, and wherein the fold region 24 is folded along the fold line 23 in the radial direction to the longitudinal axis 8 of the jacket of the outer part 12, in particular folded in a fan shape, flanged or crimped, so that the open end 5 and/or a region 30 of the closure element 29 is partially or completely covered by the fold region 24.
  • the fold line 23 is formed concentrically to the jacket of the outer part 12 with respect to a longitudinal axis 8 of the jacket of the outer part 12, and wherein the fold region 24 is arranged between the fold line 23 and the second end face 20 as viewed in the longitudinal extent 22, and wherein the fold region 24 is folded along the fold line 23 in the radial direction to
  • the combination packaging container 1 is covered with the outer part 12, but the folding area 24 is not yet folded here, partially or completely projects beyond the open end 5 and/or the area 30 of the closure element 29.
  • Fig. 3 is the combination packaging container 1 is sheathed with the outer part 12, and the folding region 24 is folded or crimped along the folding line 23, wherein the folding region 24 still projects at least slightly beyond the open end 5 of the container 2 in the axial direction, so that the open end 5 and/or a region 30 of the closure element 29 is partially or completely covered by the folding region 24.
  • closure element 29 is covered with the folded, in particular fan-shaped folded, flanged or crimped folding region 24 in such a way that removal of the closure element 29 from the open end 5 is only possible after unfolding the folding region 24 or after removing the outer part 12 from the container 2.
  • closure element 29 may be connected to the casing of the outer part 12, and the closure element 29 may be configured such that removal is possible simultaneously with removal of the outer part 12 from the container 2.
  • the closure element 29 may be designed as a sealing plate, which may be glued or otherwise connected to the casing of the outer part 12, so that the sealing plate is removed when the outer part 12 is separated.
  • the jacket of the outer part 12 may extend over a part of the container jacket 4, preferably between one quarter and two thirds of the container jacket 4.
  • Outer parts 12 are shown with different high surface lines or different maximum longitudinal extensions 22. Accordingly, the parts of the container 2 visible to an observer are of different sizes.
  • the container shell 4 of the container 2 and the shell of the outer part 12 can be arranged as shown in the Fig. 2 to 4 shown be essentially frustoconical and arranged around a common conical axis 34.
  • 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.
  • Fig. 2 and 3 shown partial axial section that the open end 5 and the closure element 29 have a collar 31 projecting over the container shell 4 of the container 2 in the radial direction to the cone axis 34, wherein a third angle 37 is formed between the cone axis 34 and an imaginary cutting line 38, which imaginary cutting 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 the same size or approximately the same size as the second angle 36.
  • Fig. 4 shows a three-dimensional view of an embodiment of a combination packaging container 1, whereby the example is representative of a multitude of conceivable shapes. Reference is made to the preceding descriptions, and to avoid unnecessary repetition, the special features of the illustrated variants are discussed below.
  • the combination packaging container 1 shown is encased in an outer part 12.
  • the container 2 is closed with a closure element 29 designed as a sealing plate or film, and a collar 31 or a flange 6 in the region of the open end 5 protrudes radially toward the longitudinal axis 8 or the cone axis 34, respectively.
