Cuff-shaped outer part and combination packaging container equipped therewith and method for separating the combination packaging container

Description

[0001] The invention relates to a sleeve-shaped outer part formed from a blank for encasing a cup-shaped inner container, as well as to a combination packaging container formed from the inner container and the outer part. However, the invention also relates to a method for separating the combination packaging container into its inner container and the outer part by separating the intended separation area.

[0002] WO 2009 / 130043 A1 describes, among other things, a sleeve-shaped outer part for forming a combination packaging container. The outer part is formed from a blank by erecting and mutually connecting ends in an overlapping region. Furthermore, an actuating means for separating a predetermined separation region is provided, which is arranged between the two end regions spaced apart in the axial direction. The actuating means is formed by an opening extending to the overlapping region, with the longitudinal side of the overlapping end forming the gripping section. In a further embodiment, an actuating tab is provided that can be removed from the casing along a U-shaped circumferential line, in which the weakening line surrounding the actuating tab ends at the longitudinal side of the overlapping end.This design has proven itself in principle, but it has not been possible to achieve a perfect separation of the intended separation area adjacent to the actuating device in all applications.

[0003] From EP 2 338 804 B1, a packaging container is known with a first container part having a container base and a container wall extending from the container base in the direction of a container edge, and with a second container part reinforcing the container wall in the form of a sleeve detachably connected to the first container part and at least partially resting on the outer surface of the container wall.

[0004] The second container part has a weakening line running from an upper edge of the second container part facing the container rim towards a lower edge of the second container part facing the container bottom. The second container part can be detached from the first container part by cutting through the second container part along the weakening line. The second container part further has a gripping area that can be manually grasped to cut through the second container part, from which the second container part can be detached from the first container part. The weakening line has an engagement section that delimits the gripping area and has a reinforced weakening and / or a cutting line, which forms the starting section for cutting through the second container part along the weakening line.Furthermore, an access area is provided adjacent to the gripping area, located on the opposite side of the weakening line from the gripping area. This access area has two predetermined separation lines running transversely to the weakening line, which terminate on one side in the engagement section of the weakening line. This ensures that the access area, after separation along the predetermined separation lines and the engagement section, remains firmly connected to the edge area of ​​the second container part that does not have the gripping area. Here, too, a perfect separation of the predetermined separation area adjacent to the gripping area could not be achieved in all applications.

[0005] Further cuff-shaped outer parts are known from JP 2009 126536 A and DE 10 2011 014844 A1.

[0006] The object of the present invention was 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 the cup-shaped inner container, by means of which a user is able to carry out a safe and, above all, continuous separation of the intended separation area. Furthermore, however, a method for separating the intended separation area and the subsequent separation of its outer part and inner container is to be created. This object is achieved by a sleeve-shaped outer part and a combination packaging container comprising a cup-shaped inner container and a sleeve-shaped outer part designed in this way, according to the claims.

[0007] The sleeve-shaped outer part according to the invention serves to enclose a cup-shaped inner container to form a combination packaging container, wherein the inner container has a container shell which is designed to taper, in particular conically, from an open end to an end closed by a base, wherein the outer part is formed from a blank, which blank, in its erected state, is wound into a shell, and a first end section and a second end section of the shell facing the latter are connected to one another in an overlapping region, wherein the outer part further has a first end face and a second end face, and the two end faces are spaced apart from one another and, in the erected state, define an overall height of the shell, and the first end face can be turned towards the base and the second end face towards the open end of the inner container, wherein at least one predetermined separation region is provided in the shell of the outer part,which predetermined separation area comprises a first separation section and a second separation section, each with a plurality of consecutively arranged predetermined separation points, in particular perforations or cuts, as well as an actuating means located between the two end faces in the direction of the overall height for separating the predetermined separation area along the two separation sections located on either side of the actuating means, wherein the two separation sections of the predetermined separation area are aligned converging towards each other as viewed in the direction of the overall height of the casing, wherein the actuating means defines a detection section with a first detection section end and a second detection section end, wherein the two detection section ends are arranged at a distance from each other as viewed in the direction of the overall height of the casing, and wherein the detection section of the actuating means is arranged or formed outside the overlap region,and wherein it is further provided that the detection section of the actuating means, viewed in the circumferential direction, is arranged or formed laterally spaced apart by an offset with respect to the separating sections of the desired separation area, which are aligned convergingly, and an imaginary straight connecting line between them, that the first detection section end of the detection section engages over an adjacent first end of the first separation section on the side facing away from the second separation section, that a first desired separation section is formed in the jacket of the outer part, viewed in the circumferential direction of the jacket, between the first detection section end and the first end of the first separation section, that the second detection section end of the detection section engages over an adjacent second end of the second separation section on the side facing away from the first separation section,that a second predetermined separation section is formed in the casing of the outer part in the circumferential direction of the casing between the second detection section end and the second end of the second separation section, that the two predetermined separation sections each form a starting section for the separation of the two separation sections of the predetermined separation area upon actuation of the actuating means, and that the predetermined separation area (22) is arranged or formed outside the overlap area (16).

[0008] The advantage achieved thereby is that the lateral offset of the detection section, extending in the circumferential direction of the casing, with respect to the separating sections, which are aligned convergingly and are located largely on both sides, and the additional ends, which overlap one another in the axial direction on both sides of the actuating means, creates a separate predetermined separating section in the casing of the outer part. This creates a separate predetermined separating section in the casing and thus in the material of the outer part between the respective detection section end and the respective end of the separating section. Upon actuation and detection of the detection section, a tearing force acting approximately tangentially with respect to the longitudinal axis and / or in the circumferential direction is exerted on each of the predetermined separating sections.This actuating force, applied at least in the tangential direction and optionally additionally in the radial direction, causes the two predetermined separation sections to separate, whereby starting from these, a further directed separation of the separation sections located on either side of the detection section takes place along their predetermined separation points in the direction of the two end faces of the casing. This ensures a directed redirection of the tearing process starting from the respective predetermined separation section towards the two separation sections extending in the direction of the overall height. Furthermore, it also makes it easier to grasp the detection section on the side of the outer part facing the inner container, since the tearing direction of the two predetermined separation sections extends essentially in the circumferential direction, allowing the actuating means with its detection section to be pulled further radially away from the inner container.The further tearing process, and thus the separation of the two sections, then takes place successively, starting from the end facing the respective detection section and moving towards the two end faces of the outer part, which are spaced apart in the axial direction or by height. In addition, depending on the overlapping arrangement of the facing end sections, a reliable tearing process can always be ensured.

[0009] Furthermore, it may be advantageous if the gripping section of the actuating means is formed by a cutting line that completely extends through the casing. This saves the user an additional cutting process in the casing area and allows them to grasp the gripping section directly in the area of ​​the cutting line and begin the cutting process for the subsequent separate disposal of the inner container and outer part.

[0010] Another embodiment is characterized by the fact that the cutting line runs in a straight line. This allows the user to capture the section at any desired location, thus initiating the opening process.

[0011] Another possible embodiment has the features that the cutting line has a curved longitudinal profile, in particular an arcuately curved longitudinal profile. This allows the gripping of the gripping section to be customized depending on the curvature, namely convex or concave.

[0012] A further embodiment provides for the actuating means to comprise an opening that completely penetrates the casing, which opening is located on the side of the detection section facing away from the overlapping area and directly adjacent to the detection section. By providing an additional opening adjacent to the detection section, the actuating means can be made even more visible and easier to visually identify.

[0013] Another embodiment is characterized by the actuating means being arranged approximately centrally between the two end faces, which are spaced apart in the direction of the overall height. This central arrangement provides a central point of engagement along the entire height or longitudinal extension. This allows for an even more uniform separation of the outer part in both directions.

[0014] A further preferred embodiment is characterized in that first predetermined separation points of the two separation sections, which are each arranged directly adjacent to the two detection section ends of the detection section, each have, on their side facing away from the detection section, a first longitudinal profile running parallel to the imaginary connecting line between the two separation sections, and each have, on their side facing the detection section, a second longitudinal profile oriented toward the detection section. The specially designed longitudinal profile of the first predetermined separation points thus enables an even more directed separation of the predetermined separation sections between the detection section and the respective ends of the separation sections.The second longitudinal profile of the first predetermined separation point, which is aligned in the direction of the detection section, creates an even more directed and better defined tear direction.

[0015] Furthermore, it may be advantageous if the second longitudinal path is curved in an arcuate manner and / or is oriented at an angle relative to the first longitudinal path. This achieves an even more precisely directed redirection of the tearing process from the respective predetermined separation sections to the two separation sections.

[0016] Another alternative embodiment is characterized in that second predetermined separation points and / or third predetermined separation points of the two separation sections, which are each arranged adjacent to the first predetermined separation points and on the side facing away from the actuating means, are oriented at an angle to the imaginary connecting line. The angularly aligned further predetermined separation points can thus facilitate and improve the separation process between immediately adjacent predetermined separation points.

[0017] A further possible and possibly alternative embodiment has the features that the angular alignment of the second predetermined separation points and / or third predetermined separation points of the first separation section and the second separation section is selected such that they are each aligned converging toward one another on the side facing away from the actuating means. Due to the converging angular alignment of the further predetermined separation points from corresponding predetermined separation points of the two separation sections, the separation behavior in the region of the predetermined separation section can be made even more reliable.

[0018] A further embodiment provides that an angle enclosed by the second predetermined separation points of the first and second separation sections or an angle enclosed by the third predetermined separation points of the first and second separation sections are configured differently from one another, starting from the actuating means toward the respective end faces. By selecting the included angles that are different from one another, the tear-open behavior can be significantly improved even as the separation process progresses between immediately adjacent predetermined separation points.

[0019] Another design is characterized by the fact that the included angle increases and thus increases from the actuating element toward the respective end faces. The changing and increasing included angle defines a roughly constant separating force over the entire opening travel.

[0020] A further preferred embodiment is characterized in that the intended separation area is arranged or formed in the first end section, and the first end section is located on the inside in the overlapping area and overlapped by the second end section on the outside. Thus, the intended separation area can be arranged directly adjacent to the overlapping longitudinal edge of the second, outer end section. By covering the second end section, an even more secure separation of the intended separation area can be achieved due to the more stable overlap area.

[0021] Furthermore, it may be advantageous if the intended separation area is arranged parallel to a longitudinal edge of the overlapping, outer second end section. This allows the intended separation area to be arranged directly adjacent to the longitudinal edge of the overlapping, outer second end section. This further provides a protective effect for the intended separation area and, moreover, largely prevents unintentional separation.

[0022] Another embodiment is characterized in that the intended separation area is arranged or formed in the first end section, the first end section is arranged on the outside in the overlap region, and the second end section is arranged on the inside and overlaps the first end section on the outside. By arranging the intended separation area on the outside in the overlap region, the gripping and grasping of the detection section of the actuating means can be facilitated by the slight spacing from the container wall.

[0023] Another possible embodiment has the features that the intended separation area is arranged parallel to a longitudinal edge of the overlapped inner second end section. Thus, the covered longitudinal edge located underneath can serve as support and stiffening for the separation process of the intended separation area.

[0024] Another embodiment is characterized by the fact that the blank is made of a cellulose material. This improves the printing and visual design of the inner container encased in the sleeve-shaped outer part, while also reducing the amount of plastic material requiring disposal.

[0025] A further preferred embodiment is characterized in that the cellulose material is made from recycled material. This allows for savings in raw material resources. Furthermore, in conjunction with the predetermined separation sections adjacent to the capture section and the two subsequent separation sections, a reliable and continuous separation process in the predetermined separation area can be enabled even when using recycled cellulose materials. Otherwise, the continuous separation process is not completely and consistently possible when using recycled materials due to the shorter fiber lengths.

[0026] The invention also relates to a combination packaging container comprising a cup-shaped inner container with a container shell, a base, a flange and a sleeve-shaped outer part designed according to the invention which surrounds the inner container at least in regions on its container shell.

[0027] This creates a combined packaging container that can be separated into its inner and outer sections even more easily and, above all, more safely after use. Even after the separation process, the outer section remains a single, integral piece, which can be easily and, above all, disposed of properly and in one piece for recycling.

[0028] A further possible embodiment of the combination packaging container has the features that the outer part further has, at its end section facing the flange, a folded edge folded inwards towards the container shell, and the inner container has an inwardly offset wall section, which wall section is arranged or formed directly adjacent to the flange in the container shell and defines a receiving space in which the folded edge is received, and that the inner container has a shoulder on the bottom side, on which shoulder the outer part is supported. In this way, in addition to the mechanical supporting effect on the bottom side, a positive-locking holder can also be created between the folded edge of the outer part and the receiving space offset inwards towards the longitudinal axis.

[0029] However, the object of the invention is also achieved by a method for separating an outer part equipped with the intended separation area designed according to the invention from an inner container, which together form the combination packaging container, in that the separation process of the intended separation area is carried out in such a way that a compressive force -F- directed in the direction of the combination packaging container is applied and at least the container jacket of the combination packaging container is spatially deformed and the applied compressive force -F- is at least partially converted into a separation force which at least partially separates the intended separation area by the spatial deformation.

[0030] The applied compressive force -F- leads at least to a spatial deformation of the container shell, whereby the compressive force is at least partially transferred from the inner container to the outer part and / or redirected to it. Depending on the orientation of the compressive force, the desired separation area is thus subjected to a separation force acting in the radial direction and / or in the circumferential direction, and the separation process of the desired separation area is carried out by the separation force at least partially, but preferably continuously, over the entire height or length of the outer part in the direction of the desired separation area. The person who is to carry out the separation process can omit the search for and finding the actuating means for the desired separation area and the subsequent tearing process.

[0031] Another advantageous approach is to place the combination packaging container on a support surface, either with its closed end or with the open end of the inner container, and then apply the compressive force -F- to the end facing away from the support surface in the direction of the support surface. Depending on the arrangement and setup of the combination packaging container, the compressive force can be easily applied to the combination packaging container and introduced into it, for example, using human force. The risk of injury can be minimized with an arrangement in which the compressive force is applied to the floor.

[0032] A further advantageous procedure is characterized in that the compressive force -F- is exerted on the combination packaging container in a parallel orientation with respect to a longitudinal axis extending between the open end and the closed end, or in an orientation angular to the longitudinal axis. Thus, with a parallel force introduction, the compressive force can be easily redirected, at least for the most part, into a tearing force acting in a predominantly radial direction, which leads to the outer part bursting open along the intended separation area. With a different force introduction direction, the separation of the intended separation area can also be caused by the spatial deformation.

[0033] Another advantageous variant of the process is one in which the compressive force -F- is applied to the combination packaging container using a pressing device. This procedure eliminates the need for the user of the combination packaging container to separate the outer part from the inner container.

[0034] For a better understanding of the invention, it is explained in more detail using the following figures.

[0035] They show in a highly simplified, schematic representation: Fig. 1 shows a combination packaging container with an inner container and an outer part, in view, partially in section; Fig. 2 shows the combination packaging container in the area of ​​its actuating means, sectioned along the lines II-II in Fig. 1, in an enlarged view; Fig. 3 a blank for forming the outer part, in an undeformed, flat position; Fig. 4 another possible embodiment of the blank for forming the outer part, in an undeformed, flat position, with a modified design of the intended separation area; Fig. 5 a combination packaging container with an inner container and an outer part and a further possible design of the intended separation area, in a view; Fig. 6 another combination packaging container with an inner container and an outer part and a modified arrangement of the overlapping end sections in the overlap area, in a view; Fig. 7 the combination packaging container according to Fig. 6 in the area of ​​its operating means cut along lines VII-VII in Fig. 6, and in an enlarged view Fig. 8 shows another possible embodiment of the combination packaging container with the inner container and the outer part, in elevation, partially in section; Fig. 9 shows a schematic representation of a possibility for applying the compressive force to the combination packaging container for separating the intended separation area, in elevation.

[0036] By way of introduction, it should be noted that in the variously described embodiments, identical parts are provided with identical reference symbols or component designations. The disclosures contained throughout the description can be applied analogously to identical parts with identical reference symbols or component designations. Furthermore, the positional information chosen in the description, such as top, bottom, side, etc., refers to the directly described and illustrated figure, and these positional information must be applied analogously to the new position in the event of a change in position.

[0037] The term "in particular" is understood below to mean that it may refer to a possible more specific embodiment or more detailed specification of an object or a method step, but does not necessarily have to represent a mandatory, preferred embodiment of the same or a mandatory procedure.

[0038] In the Fig. 1 to 3 A combination packaging container 1 is shown as an example of a multitude of possible different shapes, wherein the combination packaging containers 1 are cup-shaped or bowl-shaped. The combination packaging container 1 comprises a cup-shaped or bowl-shaped inner container 2 with a base 3 and a container shell 4. The inner container 2 further has an open end 5 on its side facing away from the base 3, wherein a flange 6 projecting outward beyond the container shell 4 can be provided in the region of its open end 5. The base 3 forms a closed end 7 for the container shell 4.

[0039] The inner container 2 is preferably formed by 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 well known and will therefore not be discussed in detail. The deep-drawing process is particularly suitable for producing the inner container 2 from a layer of a formable material using a deep-drawing tool. The inner container 2 has a sufficient wall thickness to ensure tightness during storage, use, and disposal. This manufacturing process allows relatively thin walls of the inner container 2 to be produced.

[0040] Due to the cup- or bowl-shaped design of the inner container 2, 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 sealing plate (not shown in detail) can be arranged in the area of ​​the flange 6 or connected to it. In this case, the flange 6 forms a sealing flange.

[0041] In the axial direction and thus in the direction of the longitudinal axis 8, the inner container 2 has a container height 9 between its open end 5, in particular the flange 6, and the base 3, whereby the receiving volume of the inner 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 inner container 2.

[0042] The container shell 4 is understood to be that section of the inner container 2 which extends predominantly axially between the open end 5, in particular the flange 6, and the base 3. The inner container 2 and its container shell 4 are preferably designed such that they taper conically from the open end toward the base.

[0043] Furthermore, the container shell 4 of the inner container 2 can have a backing 10 in its peripheral section adjacent to the base 3. The backing 10 is also part of the container shell 4, but, viewed in axial section, is offset inwards with respect to an imaginary, straight connecting line between the flange 6 and the base 3. The backing 10, in turn, has at least two backing wall sections (not designated in more detail), wherein the two backing wall sections, viewed in axial section, have a different inclination or direction with respect to the longitudinal axis 8 than the rest of the container shell 4. In this case, the backing 10 is offset inwards and thus in the direction of the receiving space compared to the straight arrangement of the container shell 4 between the flange 6 and the base 3, viewed in axial section.

[0044] Viewed in axial section, the first rear wall section, which directly adjoins the base 3, is arranged or configured to extend predominantly in the direction of the container height 9 toward the open end 5. The further rear wall section extends in a predominantly perpendicular direction with respect to the container height 9, starting from the end of the first rear wall section facing away from the base 3 toward the container shell 4. In the present exemplary embodiment, the further rear wall section forms a stacking shoulder. This stacking shoulder serves to support a similar combination packaging container 1 with its base 3, in particular the edge-side transition section between the base 3 and the container shell 4.

[0045] Furthermore, the inner container 2 can have a shoulder 11 or a bead projecting towards the side facing away from the longitudinal axis 8 in the immediate transition area between the bottom 3 and the container shell 4, in particular between the bottom 3 and the rear section.

[0046] The combination packaging container 1 further comprises an outer part 12 which is sleeve-shaped or jacket-shaped and surrounds the inner container 2 in the region of its container jacket 4 at least in sections or regions.

[0047] The previously described shoulder 11 can, for example, serve to hold the sleeve-shaped outer part 12 in a locked manner on the inner container 2. In this case, the sleeve-shaped outer part 12 is supported with its first end face 19 facing the bottom 3 of the inner container 2 on this shoulder 11 formed in the transition region. The shoulder 11 can thus also be referred to as a locking means for holding the outer part 12 on the inner container 2. A further locking means in the region of the open end 5 can be the flange 6, for example. 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.

[0048] 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, as is already sufficiently known. The blank 13 is usually printed in its undeformed, flat position and, if necessary, provided with an additional coating. A cellulose material is usually used as the material, although this can also be cardboard or strong paper produced using a recycling process. If a layer or ply of the outer part 12 is formed from 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, labels and product information.

[0049] The sleeve-like or jacket-like outer part 12 leads to an additional reinforcement or stiffening effect of the inner container 2 and thus of the entire combination packaging container 1.

[0050] This provides high strength and good thermal insulation on the one hand, and optimal light protection for the contents of the packaging container on the other.

[0051] In particular, it can also be provided that the cardboard is additionally coated or sealed with a water-repellent material in the area of ​​the cut edges. This is particularly advantageous when the combination packaging containers 1 are exposed to increased moisture 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.

[0052] The cuff-shaped outer part 12 is wound from the mostly flat blank 13 into a sheath. By winding the blank, mutually facing end sections 14, 15 are then connected to one another in a simplified overlap region 16. This is achieved by a so-called overlap seam, by means of which the first end section 14 and the second end section 15 adhere to one another, e.g., by means of an adhesive. The winding and subsequent connection of the two end sections 14, 15 can be carried out, as is already well known from the prior art, for example, by gluing. As an example, reference is made to EP 0 408 515 B1. The first end section 14 of the blank 13 ends with a first longitudinal edge 17, and the second end section 15, in turn, ends with a second longitudinal edge 18.In the overlapping area 16, the two longitudinal edges 17, 18 run approximately parallel to each other, wherein, viewed in the circumferential direction, the overlapping area 16 is formed therebetween with an overlap width.

[0053] The outer part 12 further comprises the first end face 19 and the second end face 20, wherein the two end faces 19, 20 are spaced apart from one another and, in the erected state, define an overall height 21 of the shell. The previously described longitudinal axis 8 can also define the common longitudinal axis for the outer part 12, particularly when the outer part 12 is in its assembled position on the inner container 2. The overall height 21 of the shell is usually 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.

[0054] In order to enable a defined severing and, associated with this, subsequent separate disposal of the inner container 2 and outer part 12 for a consumer, at least one predetermined severing region 22 is provided in the casing of the outer part 12. The predetermined severing region 22 here comprises a first severing section 23, a second severing section 24, and an actuating means 25 for starting and beginning the severing process of the predetermined severing region 22 along the two severing sections 23, 24. The actuating means 25 is arranged between the two end faces 19, 20, viewed in the direction of the overall height 21 of the casing. It is advantageous if the actuating means 25 is arranged approximately centrally between the two end faces 19, 20, which are spaced apart from one another in the direction of the overall height 21, wherein this essentially corresponds to half the overall height 21.The term "central" refers to half the dimension of the actuating means 25 in the direction of the overall height 21 or the longitudinal axis 8. The two separating sections 23, 24 are provided on both sides of the actuating means 25 and each extend in the direction of the respective end face 19, 20.

[0055] Viewed in the direction of the overall height 21 of the casing, the two separating sections 23, 24 of the intended separating region 22 are each aligned so as to converge from the two end faces 19, 20 and thus define an imaginary, straight connecting line 26 between them, which is shown in dashed lines. The converging alignment of the two separating sections 23, 24 is in each case related to the direction of the actuating means 25. The two separating sections 23, 24 can either be aligned so as to be flush with one another, viewed in the direction of the overall height 21 of the casing, or they can run at a slight incline with respect to the first longitudinal edge 17 in the direction of the actuating means 25 located between them. This slight inclination can further improve the separating process after the two separating sections 23, 24 have been separated towards the two end faces 19, 20.

[0056] Depending on the design of the predetermined separation points, which will be described in more detail later, the imaginary connecting line 26 is assumed to run at the center of the predetermined separation points. The actuating means 25, in turn, defines a detection section 27 with a first detection section end 28 and a second detection section end 29 spaced apart from one another in the direction of the overall height 21. Thus, the two detection section ends 28, 29 are arranged or end at a distance 30 from one another in the direction of the overall height 21 of the casing. Furthermore, it can also be seen that the detection section 27 of the actuating means 25 is arranged or formed outside the overlap region 16.

[0057] An arrangement of the actuating means 25 is provided here in which the detection section 27, viewed in the circumferential direction, is arranged or formed laterally spaced by an offset 31 relative to the converging separating sections 23, 24 of the desired separating region 22 and the imaginary straight connecting line 26 between them. The offset 31 can have a value selected from a range of values ​​with a lower limit of 1.0 mm and an upper limit of 10.0 mm. Preferably, the range of values ​​can have a lower limit of 2.0 mm and an upper limit of 6.0 mm.

[0058] The first separating section 23, in turn, has a first end 32 facing the actuating means 25, and the second separating section 24 has a second end 33 facing the actuating means 25. In the region of the imaginary connecting line 26 between the two ends 32, 33, the casing is formed without interruption due to the intended lateral offset 31 of the actuating means 25. The arrangement of the two ends 32, 33 of the separating sections 23, 24, which are spaced apart from one another in the direction of the overall height 21, with respect to the detection section 27 forming the actuating means 25 is selected such that the first detection section end 28 of the detection section 27 overlaps the adjacent first end 32 of the first separating section 23 on the side facing away from the second separating section 24.Due to the lateral offset 31 of the detection section 27 to the side facing away from the overlap region 16, a first predetermined separation section 34 is formed in the circumferential direction in the jacket of the outer part 12 between the first detection section end 28 and the first end 32 of the first separation section 23.

[0059] It is also provided that the second detection section end 29 of the detection section 27 overlaps the adjacent second end 33 of the second separating section 24 on the side facing away from the first separating section 23. Thus, analogous to the first intended separating section 34, a second intended separating section 35 is also formed in the casing of the outer part 12 between the second detection section end 29 and the second end 33 of the second separating section 24, viewed in the circumferential direction. The two intended separating sections 34, 35 are formed by the reduced dimension of the casing material between the respective detection section end 28 or 29 and the respective end 32 or 33. The two ends 32 and 33 of the separating sections 23, 24 are arranged closer to one another than the two detection section ends 28 and 29, which are spaced apart by the distance 30.

[0060] This makes it possible for a user of the combination packaging container 1 to grasp the actuating means 25 with its grasping section 27, then separate the two predetermined separation sections 34, 35 starting from the grasping section 27 up to the respective ends 32, 33 of the two separation sections 23, 24, and subsequently separate the two separation sections 23, 24 until the jacket is completely severed. This allows the outer part 12 to be easily separated from the inner container 2 and separated for disposal. The two predetermined separation sections 34, 35 each form starting sections for the separation of the two separation sections 23, 24.

[0061] Each of the two separating sections 23, 24 comprises a plurality of predetermined separation points arranged one behind the other in a row, which are usually formed as perforations, in particular also as short cuts, in the material of the outer part 12.

[0062] This exemplary embodiment shows that the shape and position of the predetermined separation points can be selected differently from one another. Therefore, those predetermined separation points located directly adjacent to the respective detection section ends 28, 29 are referred to as first predetermined separation points 36. The further predetermined separation points provided subsequently toward one of the two end faces 19, 20 are referred to as second predetermined separation points 37 and third predetermined separation points 38.

[0063] The predetermined separation points 36, 37, 38 are aligned with respect to a plane 39 centrally and in normal alignment to the longitudinal axis 8 - see Fig. 1 - are designed and arranged in a mirror image of each other. Therefore, only those predetermined separation points 36, 37, 38 located in the area of ​​the first separation section 23 will be described in detail and are to be transferred analogously to the second separation section 24.

[0064] The first predetermined separation point 36 has, on its side facing away from the detection section 27, a first longitudinal profile 40 extending essentially parallel to the imaginary connecting line 26 between the two separation sections 23, 24 or parallel to one of the longitudinal edges 17, 18. However, it would also be possible to align the first longitudinal profile slightly obliquely in the direction of the actuating means 25.

[0065] Adjacent to the first longitudinal profile 40 is a second longitudinal profile 41, which is located on the side facing the detection section 27 and is oriented so as to project toward the detection section 27. Due to the approximately parallel orientation of the first longitudinal profile 40, it is designed to run in a straight line. The first longitudinal profile 40 and the second longitudinal profile 41 together form the first predetermined separation point 36 and are formed, for example, by a punching process and preferably completely penetrate the thickness of the blank 13 to form the outer part 12. The second longitudinal profile 41 of the first predetermined separation point 36 can be curved in an arcuate manner. However, an angular and straight design of the second longitudinal profile 41 of the first predetermined separation point 36 in the direction of the actuating means 25 would also be possible. In any case, the second longitudinal profile 41 of the first predetermined separation point 36 ends before reaching the detection section 27.

[0066] The second and / or third predetermined separation points 37, 38 of the two separation sections 23, 24, located downstream of the first predetermined separation points 36, can have an orientation extending at an angle to the imaginary connecting line 26. The angular orientation of the second predetermined separation points 37 and / or the third predetermined separation points 38 of the first separation section 23 and the second separation section 24 can be selected such that they are each aligned converging toward the side facing away from the actuating means 25. In this case, the predetermined separation points 37, 38 are to be considered as being symmetrical relative to the normal plane - plane 39. Preferably, the second predetermined separation points 37 can be longer than the subsequent third predetermined separation points 38.

[0067] Furthermore, it is possible for an angle 42-1, 42-2 enclosed by the second and / or third predetermined separation points 37, 38 of the first separation section 23 and by the second and / or third predetermined separation points 37, 38 of the second separation section 24 to be configured differently from one another, starting from the actuating means 25 and extending to the respective end faces 19, 20. As previously mentioned, the angle 42-1 between the second predetermined separation points 37 or the angle 42-2 between the corresponding third predetermined separation points 38 is always to be considered. The enclosed angle 42-1, 42-2 can be configured to increase and thus be larger, starting from the actuating means 25 and extending to the respective end faces 19, 20. In the present exemplary embodiment, the enclosed angle 42-2 between the respective third predetermined separation points 38 is always selected to be the same, but larger than the angle 42-1 enclosed by the second predetermined separation points 37.

[0068] The design of the actuating means 25 and its detection section 27 can be selected in various ways. In the present exemplary embodiment, the detection section 27 is formed by a cutting line that completely penetrates the casing. The cutting line here has a straight longitudinal profile. Further design options for the predetermined separation area 22, in particular for its actuating means 25, are explained in more detail in the following figures.

[0069] The overlap region 16 between the two end sections 14, 15 can be selected such that the intended separation region 22 is arranged or formed in the first end section 14, and the first end section 14 is located on the inside in the overlap region 16 and overlapped by the second end section 15 on the outside. In this exemplary embodiment, the intended separation region 22 is arranged parallel to the second longitudinal edge 18 of the overlapping outer second end section 15. Furthermore, it can also be provided that the intended separation region 22 is arranged or formed outside the overlap region 16.

[0070] In the Fig. 4 a further and possibly independent embodiment of the blank 13 for forming the outer part 12 is shown, wherein again the same reference numerals or component designations are used for the same parts as in the previous Fig. 1 to 3To avoid unnecessary repetition, please refer to the detailed description in the previous Fig. 1 to 3 pointed out or referred to.

[0071] The basic structure and arrangement of the predetermined separation area 22 is analogous to that described in detail above. Therefore, only the differences will be discussed in more detail.

[0072] The intended separation area 22 of the blank 13 comprises the two separation sections 23 and 24 as well as the gripping section 27 located therebetween. In addition to the gripping section 27, the actuating means 25 further comprises an opening 43 that completely penetrates the casing. The opening 43 is arranged on the side of the gripping section 27 facing away from the overlapping area 16 and directly adjacent to the gripping section 27. Furthermore, the opening 43 ends at the cutting line of the gripping section 27. The provision of the opening can make it easier for a user to grip the gripping section 27.

[0073] In the Fig. 5 a further and possibly independent embodiment of the blank 13 for forming the outer part 12 is shown, wherein again the same reference numerals or component designations are used for the same parts as in the previous Fig. 1 to 4To avoid unnecessary repetition, please refer to the detailed description in the previous Fig. 1 to 4 pointed out or referred to.

[0074] The intended separation area 22 of the blank 13 comprises the two separation sections 23 and 24 as well as the detection section 27 located therebetween. In contrast to the Fig. 1 to 4 In the embodiments shown, the cutting line for forming the gripping section 27 has a curved longitudinal profile. Preferably, the longitudinal profile is curved in an arc. In the present embodiment, the gripping section 27 has a convex longitudinal profile with a curvature facing away from the overlap region 16. This allows the formation of a type of actuating tab, which can further facilitate gripping and actuation during the severing process.

[0075] Regardless of this, a concave curvature could also be provided for the formation of the cutting line.

[0076] Furthermore, the previously mentioned Fig. 4 The opening 43 described above and immediately adjacent to the cutting line can be provided in the casing to form the actuating means 25. The formation of the predetermined separation sections 34, 35 and their predetermined separation points 36, 37 and 38 can be carried out analogously to that already described above.

[0077] In the Figs. 6 and 7 a further and possibly independent embodiment of the blank 13 for forming the outer part 12 is shown, wherein again the same reference numerals or component designations are used for the same parts as in the previous Fig. 1 to 5 To avoid unnecessary repetition, please refer to the detailed description in the previous Fig. 1 to 5 pointed out or referred to.

[0078] The design and arrangement of the intended separation area 22 in the first end section 14 of the blank 13 can be carried out according to a previously described embodiment. The intended separation area 22 in turn comprises the two separation sections 23 and 24 located on either side of the actuating means 25.

[0079] In contrast to the previously described embodiments, in which the first end section 14 with the predetermined separation region 22 located therein is overlapped by the second end section 15 in the overlap region 16, here the first end section 14 is arranged on the outside in the overlap region 16 and thus overlaps the second end section 15.

[0080] The predetermined separation region 22 is thus also arranged or formed in the first end section 14, wherein the second end section 15 is arranged inwardly in the overlapping region 16 and thus overlapped.

[0081] In the Fig. 8The combination packaging container 1 is shown partially sectioned with the inner container 2 and the outer part 12 surrounding the container shell 4. The basic structure of the inner container 2 and the outer part 12 corresponds to that previously described in the Fig. 1 to 7 Therefore, the same reference symbols and component designations are used for the same parts as in the previous Fig. 1 to 7 To avoid unnecessary repetition, please refer to the detailed description in the previous Fig. 1 to 7 The previously described separation area 22 with its actuating means 25 and the separating sections 23, 24 on both sides is designed analogously to the previous Fig. 1 to 7 For the sake of clarity, many of the previously used additional reference symbols have been omitted.

[0082] In the area of ​​the closed end 7 of the inner container 2, the inner container 2 has a radially projecting shoulder 11, against which the first end face 19 of the outer part 12 rests in its joined position with the inner container 2, on the side or direction facing away from the open end 5. In the area of ​​the open end 5 of the inner container 2, a holding arrangement 44 is provided directly adjacent to the flange 6 in order to additionally hold the outer part 12 to the inner container 2, in particular to secure it thereto in a form-fitting manner. The section of the holding arrangement 44 is shown on an enlarged scale in detail "X" below the combination packaging container 1 on the left.

[0083] For this purpose, the sleeve-shaped outer part 12 has its own folded edge 45. The folded edge 45 is folded inwards in the direction of the longitudinal axis 8 or in the direction of the container shell (4), whereby no additional disturbing edges are arranged or formed on the outer side of the sleeve-shaped outer part 12 facing the viewer. The folded edge 45 can be provided or formed over the entire circumference or approximately over the entire circumference of the outer part 12. Preferably, however, it is possible to form the folded edge 45 not over the entire circumference of the outer part 12, but only in sections. A multiple arrangement of the same distributed over the circumference is possible. To receive and support the folded folded edge 45, the container shell 4 has an inwardly offset wall section 46 which forms a receiving space 47 for the folded edge 45.The receiving space 47 is preferably formed continuously over the entire circumference, but can also be formed only in segments or sections. As a transition from the inwardly offset wall section 46 and the remaining container shell 4, a stepped surface 48 is provided, extending from the inwardly offset wall section 46 to the side facing away from the longitudinal axis 8. The inwardly folded folded edge 45 is supported by its front edge on the stepped surface 48.

[0084] When joining the sleeve-shaped outer part 12 to the inner container 2, the folded edge 45, together with the outer part 12, is pushed toward the flange 6 until the folded edge 45 snaps completely into the designated receiving space 47 in the region of the open end 5 of the inner container 2. This allows for additional mechanical locking of the sleeve-shaped outer part 12 to the inner container 2. The folded edge 45 is preferably placed circumferentially and continuously against the shell or wall of the sleeve-shaped outer part 12 during the flanging process.

[0085] The holding arrangement 44 between the outer part 12 and the inner container 2 could also be formed by at least one holding lug protruding from the container shell 4 on the side facing away from the longitudinal axis 8 and a recess or holding opening arranged or formed in the outer part 12. The holding lug protrudes into the recess or holding opening and thus holds the outer part 12 to the inner container 2.

[0086] To date, the outer part 12 has generally been additionally secured against accidental separation with an adhesive at at least one adhesive point or an adhesive spot on the container shell 4 of the inner container 2 if the support of the outer part 12 on the bottom shoulder 11 is no longer sufficient due to excessive dimensional differences. Thus, during waste separation, the outer part 12 must first be separated in the designated separation area 22 formed therein, then the adhesive point must be removed, and only then can the sorted, separate disposal be carried out.

[0087] The additional adhesive may be provided, but is not required for the Fig. 9 described embodiment is not absolutely necessary and can be omitted entirely.

[0088] In the Fig. 9One possibility for carrying out the separation of the intended separation area 22 is shown in simplified form according to the various embodiments described above. The combination packaging container 1 is shown in its undeformed original form.

[0089] After removing the goods contained in the combination packaging container 1, usually a food product or a consumable, the outer part 12 must be detached from the inner container 2 for proper and separate disposal. The material of the outer part 12 is cellulose (cardboard, strong paper, or the like), and that of the inner container 2 is a plastic material.

[0090] Until now, for proper and sorted disposal, the user has to detach the outer part 12 from the inner container 2. This is usually done by grasping the actuating means 25 and the subsequent separation process by radially or tangentially lifting one of the end sections 14 or 15. This severes the intended separation area 22, and the outer part 12 can be removed from the inner container 2.

[0091] To carry out the separation process of the predetermined separation area 22, it is proposed here, by way of derogation, to exert a compressive force -F- in the direction of the combination packaging container 1 and, in the process, to carry out a desired spatial deformation of at least the container shell 4. Preferably, the compressive force -F- is exerted in the direction of the longitudinal axis 8 or in an angular force orientation to this. In this case, the entire combination packaging container 1 is spatially deformed. The applied compressive force -F- is at least partially converted by the deformation of the combination packaging container 1 into a separation force that separates the predetermined separation area 22 along the predetermined separation points 36 and 37, the predetermined separation sections 34 and 35, and the separation sections 23 and 24.

[0092] The application of the compressive force -F- eliminates the need to search for the desired separation area 22, to detect the actuating means 25 and the subsequent separation process.

[0093] The simplest way, according to the process proposed here, is to place the combination packaging container 1 intended for separation either with its closed end 7 or its open end 5 of the inner container 2 onto a support surface formed, for example, by a solid base, and then the person exerts the compressive force -F- on the end facing away from the support surface in the direction of the support surface. The support surface or the solid base can be, for example, the floor, a table or a worktop. The compressive force -F- can be applied directly by the person with their hand(s) or with their foot. In order to give the person who is to apply the compressive force -F- to separate the intended separation area 22 onto the combination packaging container 1 an indication, a marking or an indication regarding the implementation of the separation process can be attached or arranged, for example, on the base 3 of the inner container 2 and / or on the outer part 12.The marking on the base 3 can be applied or arranged, for example, in the area of ​​the longitudinal axis 8 and / or on the outer circumference on the base side.

[0094] However, a dedicated pressure device could also be provided, into which the combination packaging container 1 to be separated is inserted, and the pressure force -F- is then mechanically applied. It would also be possible, however, for the separation of the intended separation area 22 to be carried out during waste disposal by a pressing device or the like, and for the pressure force -F- to be applied by this device. This usually occurs when reducing the transport volume.

[0095] This allows the user of the combination packaging container 1 to forgo the separation process and can dispose of the entire combination packaging container 1. The separation process of the intended separation area 22 is carried out mechanically by a press or a crushing device during collection and / or waste disposal.

[0096] The embodiments show possible embodiments, whereby it should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but rather various combinations of the individual embodiments with each other are also possible and this possibility of variation lies within the skill of the person skilled in the art in this technical field due to the teaching of technical action by means of the objective invention.

[0097] The scope of protection is determined by the claims. However, the description and drawings must be used to interpret the claims. Individual features or combinations of features from the various embodiments shown and described may represent independent inventive solutions. The problem underlying these independent inventive solutions can be derived from the description.

[0098] All information on value ranges in this description is to be understood as including any and all sub-ranges thereof, e.g. the information 1 to 10 is to be understood as including all sub-ranges starting from the lower limit of 1 and the upper limit of 10, ie all sub-ranges begin with a lower limit of 1 or greater and end with an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1, or 5.5 to 10.

[0099] For the sake of clarity, it should finally be pointed out that, in order to better understand the structure, some elements have been shown out of scale and / or enlarged and / or reduced in size. Reference symbol list
