Description

Combination packaging container

The invention relates to a combined packaging container and to a method for producing such a combination packaging container, as described in claims 1 and 12.

WO 98/013270 A1 and the EP 0 929 455 B1 resulting therefrom describe a method for producing a cup-shaped combination packaging container, in which the sleeve is pushed over the inner container. The inner container has a container jacket, a bottom and a flange projecting outwardly beyond the container jacket in the region of its open end. Furthermore, the inner container has a container height in the axial direction between the open end and the bottom and defines a receiving space. The container casing of the inner container has in its peripheral portion adjacent to the bottom a rear pull with rear wall sections, wherein viewed in axial section, the wall adjoining the ground first Hinterzug predominantly towards the container height towards the open end extends and the other Hinterzugwandab- cut to form a stacking shoulder extends in a predominantly vertical direction with respect to the container height to the container shell. As an axial fixation, the inner container has, in the region of its two mutually distanced ends, on the one hand an edge bead and on the other hand a flange. Between these, the cuff-shaped outer part extends and also additionally supported on it.

WO 2006/129066 A2 describes a container or cup which comprises a container casing, a bottom and a flange projecting outwardly beyond the container casing in the region of its open end. The container has a container height in the axial direction between an open end and the bottom, thereby defining a receiving space. The container casing of the container has in its adjacent to the bottom peripheral portion of a rear pull with rear wall sections, wherein seen in axial section, the subsequent to the ground, first Hinterzug wall section extends predominantly in the direction of the container height towards the open end. The further rear wall section extends in axial section seen in a predominantly vertical direction with respect to the container height to form a stacking shoulder towards the container shell. On this stack shoulder a separating element is arranged lying on top, which divides the receiving space of the container in the direction of the container height formed in both sides of the separating element part receiving spaces. The partition is removable as needed from the exception space, whereby access to the bottom side part receiving space is made possible.

A similarly trained cup for the preparation of beverages has become known from DE 1 941 965 A. This cup has a container shell in which the cup has a container height in the axial direction between the open end and the end closed to the bottom. The container casing of the cup has, in its circumferential portion adjacent to the bottom, a rear pull with rear pull wall sections. As seen in axial section, the first rear wall section, which adjoins the floor immediately, extends predominantly in the direction of the container height towards the open end. Seen in axial section, the further rear wall section extends in a predominantly vertical direction with respect to the container height and merges with the container shell to form a stacking shoulder. The receiving space of the container is divided by a separating element in the direction of the container height formed in both sides of the separating element part receiving spaces. In this case, the separating element rests on the stacking shoulder and is removably held by tearing at this.

Another combination packaging container with a detachable jacket-shaped outer part has become known from EP 0 408 515 A. In this case, the outer part has a separating line extending between its end regions and in the direction of a longitudinal axis, which is arranged in the overlapping region of the two ends connected to one another by an overlapping seam. By means of a handle flap, the predetermined separation strip can be grasped and thus actuated, whereby the desired separation can take place so as to be able to remove the outer part, which is usually formed from a cardboard or paper material, from the inner container. For stacking, a stacking shoulder is provided in the region of the open end, which is supported at identically designed and nested containers at the top of the outwardly projecting flange.

In the case of the containers already having a separating element, stacking often led to damage of the separating element, which subsequently led to leaks in the separated part receiving space up to the unusability of the stored product. Furthermore, filling of the beaker with hot liquid could not be carried out in all cases of application, in particular after removal of the separating element, because the container jacket became too hot on its outside and thus it was difficult to use. There was no additional sheathing for this type of container.

The present invention has for its object to provide a combination packaging container comprising an inner container and a surrounding the inner container in the region of its container shell cuff-shaped outer part, in which its receiving space is divided by a separating element in part receiving spaces and still a proper stacking of similar combination packaging containers without damaging the separating element is possible. In addition, even a usability is to be made possible, in which a hot medium is filled in the receiving space. This object of the invention is solved by the features of claim 1. The advantage resulting from the features of claim 1 lies in the fact that the possibility is also created for combination packaging containers to subdivide the receiving space in part receiving chambers arranged on both sides of the separating element. Since such combination packaging containers have an inwardly projecting stacking shoulder in their bottom region, similarly designed combination packaging containers can be stacked into one another into a stack of cups. Due to the design of the combination packaging container with the inner container and the outer part, the rear pull can be provided in the bottom region of the inner container for connection to the separating element. This makes it possible, after the production of the combination packaging container, to fill a product to be stored in the receiving space and then to close the product through the separator against the external environment. Due to the angled formation of the rear wall sections with the two rear pull it comes in this transition area to a solidification or stiffening of the container shell of the inner container, creating the possibility created even with already applied outer part to attach the separator and the container shell, namely in the direction the container height extending rear wall section to connect. Another advantage also results from the fact that the formation of the stack shoulder projecting inwards into the receiving space leads to a reduction in the cross-sectional dimension in this region. comes over the sections of the container shell between the stacking shoulder and the open end. Since the connection of the separating element with the mantle part surface of the first withdrawal wall section is usually carried out by a sealing process, takes place in the area between the stacking shoulder and the open end always sufficient radial distancing from the container shell of the inner container. Thus, the stamp, which serves for connection of the separating element with the casing part surface of the first pull-out Wandab cut, only immediately before the connecting region in contact with the inner container. As a result, damage, as may occur, for example, in the case of imprecise positioning and insertion of the stamp into the receiving space, in that region of the inner container which is located between the stacking shoulder and the open end, is avoided.

Also advantageous is a further embodiment according to claim 2, since the separating element is thus created with a cup-shaped design and at the same time on the one hand, the connecting element is created, which is connected to the first Hinterzugwandabschnitt and on the other hand at the same time the receiving space dividing partition is formed , So there is a single component.

Also advantageous is an embodiment according to claim 3, since thus damage to the separating element, in particular of its due to the distancing even with a stacking of several identical combination packaging containers

Partition, secured avoided. In addition, but also for the connection process, the inherent rigidity of the rear can be used with, so as to achieve a perfect connection operation between the separating element and the first Hinterzugwandabschnitt.

The embodiment according to claim 4 makes it possible for no disturbing elements or components of the separating element to protrude into the stacking area of the stacking shoulder.

As a result, unintentional jamming of stacked combination packaging containers in stacks of cups can be avoided.

According to another embodiment variant according to claim 5 so can be taken into account on a wide variety of contents and depending on the selected medium on the nature of Ver the separation process against the external atmosphere or the external environmental conditions are determined.

Also advantageous is a development according to claim 6, since the removal of the separating element in its separating position of the receiving space from the combination packaging container is thus made possible in a simple manner.

In the embodiment according to claim 7 is advantageous that can be dispensed with additional fastening means between the outer part and the cup-shaped inner container. Thus, a simple locking connection will be created, after use also a proper, proper separation for waste disposal for the consumer is possible.

The development according to claim 8 ensures that the outer part thus assumes a sufficient support function for the container casing of the inner container and thus simple stacking forces can be transmitted from the flange of the inner container to the ground.

As a result of the design according to claim 9, a large number of inner containers can be produced cost-effectively with a known forming process, which can additionally be produced with a very small wall thickness. This can save raw material resources. In addition, a very short cycle time can be selected by the deep-drawing process, with a stable and good hanzuhabender combined packaging container is still created by the sheathing of the inner container through the outer part.

Also advantageous is an embodiment according to claim 10, since an isolation space is created by the at least partially distancing between the container shell and the outer part, making it easier for the user to keep the combined packaging container still good even with a hot medium. This minimizes the direct heat transfer from the hot product to the outside of the combination packaging container.

Through this insulation layer but also the temperature decrease of the hot filling material can be reduced duration over a longer period of use. According to one embodiment, as described in claim 11, as an even better insulation effect is achieved, since at least partially between the inside of the outer part and the container shell an air flow is made possible. As a result, the combined packaging container can be easily handled even when the contents are filled very hot, without the user exposing his or her fingers to too high a temperature.

The object of the invention is, however, independently of this also solved by a method according to the features specified in claim 12. The advantages resulting from the combination of features of this claim are that even with combined packaging containers the possibility is created of subdividing the receiving space in part receiving chambers arranged on both sides of the separating element. Since such combination packaging containers have an inwardly projecting stacking shoulder in their bottom region, similarly designed combination packaging containers can be stacked into one another into a stack of cups. Due to the design of the combination packaging container with the inner container and the outer part, the rear pull can be provided in the bottom region of the inner container for connection to the separating element. This makes it possible, after the production of the combination packaging container to fill a product to be stocked in the receiving space and then complete the contents through the separating element against the external environment. Due to the angled design of the drawstring wall sections with the two Hinterzug occurs in this transition region to a solidification or stiffening of the container shell of the inner container, whereby the possibility is created, even with already applied outer part to attach the separator and the container shell, namely itself in the direction of the container height extending tail wall section to connect. Another advantage is also the fact that by the formation of the projecting into the receiving space inside

Stacking shoulder results in a reduction of the cross-sectional dimension in this area relative to the portions of the container shell between the stacking shoulder and the open end. Since the connection of the separating element with the mantle part surface of the first withdrawal wall section is usually carried out by a sealing process, also takes place in the area between the stacking shoulder and the open end always sufficient radial distancing from the container shell of the inner container. Thus, the stamp, which serves for connection of the separating element with the casing part surface of the first pull-out Wandab cut, only immediately before the connecting region in contact with the inner container. Thereby Damage, such as may occur in an imprecise positioning and insertion of the punch in the receiving space, in that region of the inner container, which is located between the stacking shoulder and the open end, avoided. It is advantageous in the process steps selected in claim 13, that so from a planar blank of the approximately cup-shaped separator is formed, which is introduced for the connection process together with the stamp in the receiving space of the combination packaging container, there positioned at the intended location and subsequently connected to its first Hinterzugwandabschnitt.

Furthermore, a procedure according to the features specified in claim 14 is advantageous because it starts from a flat blank, which can be placed on the stacking shoulder before the connection process, the forming and positioning and subsequent bonding takes place only during the connection process. This can save an additional work process.

A further advantageous procedure is described in claim 15, whereby additional forming forces can be avoided during the forming process directly in the inner container and only one insertion, positioning and connecting the separating element to be performed with the first Hinterzugwandabschnitt.

Also advantageous is a method variant according to claim 16, because so no disturbing elements or components of the separating element protrude into the stack area of the stacking shoulder. As a result, unintentional jamming of stacked combination packaging containers in the stack of cups can be avoided.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures. Each shows in a highly schematically simplified representation:

1 shows a combination packaging container in a diagrammatically simplified representation; FIG. 2 shows the combination packaging container according to FIG. 1, in axial section; FIG.

3 shows the combination packaging container according to FIGS. 1 and 2, during the forming and connecting process with the separating element;

Fig. 4 shows another possible embodiment of a combination packaging container, in axial section.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position.

In Figs. 1 to 3 a possible embodiment is shown as an example for forming a combination packaging container 1. In the context of combination packaging containers 1, such cups or cup-shaped packaging containers are understood to include a cup-shaped or inner container 2 and a sleeve-shaped outer part 3 surrounding the inner container 2 at least in regions. In this case, the cross section or the spatial form can be chosen very different.

The inner container 2 is preferably formed by a deep-drawn component, which can be produced quickly and, above all, in a short cycle time. The process of deep drawing is well known and will therefore not be discussed further. The deep-drawing process is particularly suitable for producing from a reshapeable layer of a deformable material by means of a deep-drawing tool, the inner container 2 with a sufficient wall thickness, which ensures the tightness during storage, use up to the disposal. By this manufacturing process, relatively thin wall thicknesses of the inner container 2 can be made. The material for the formation of the layer to be formed, in particular the film, may be selected from the group of polypropylene (PP), polystyrene (PS), polyester, an alternative plastic or a compostable material. Both transparent and colored material can be used. The cup-shaped inner container 2 to be produced is formed from the layer or film under the effect of temperature and / or pressure.

Polypropylene (PP) containers have good strength and low-density stiffness with good resistance to stress cracking. They maintain their properties even at higher temperatures, which also a packaging of warm goods or heating of the contents is possible.

Polystyrene (PS) is clear in its basic form with high rigidity and hardness. However, it is also possible to color the material in order to adapt the appearance of the container to the respective requirements. By using these materials, it is possible due to their high strength, to reduce the wall thicknesses of the inner container 2 to a minimum, which in addition to the cost also reduces the weight and thus brings benefits, inter alia, during transport of the combination packaging container 1. Furthermore, polystyrenes have advantages in terms of economic processability and good formability. Both homopolymers of monostyrene, as well as copolymers or blends can be used. The specified values or strengths are achieved with commercially available polystyrenes having a modulus of elasticity according to EN ISO 527 in the range from 1 × 10 3 to 5 × 10 3 N / mm ² . The material polypropylene (PP) has the disadvantage of a greater shrinkage behavior compared to the material polystyrene (PS).

The polyesters belong to the large family of synthetic polymers. Thus, the advantage is achieved that in addition to the low material costs a simple processability and good performance properties are ensured.

An alternative to conventional, often no longer reusable and thus after their use to waste packaging materials are packaging, which to its über- weighing part or else are formed entirely from compostable materials. They are made of biodegradable materials and consist partly or completely of renewable raw materials, such as starch, cellulose or polylactic acid. These materials are suitable as packaging materials for various products, for example for food.

For example, plastics and compostable materials or the like have proven themselves. Thus, for example, polypropylene (PP), polyamide (PA), polystyrene (PS), polycarbonate (PC) and unspecified further, deep-drawing materials can be used here.

The cuff-shaped outer part 3 is preferably formed from a cardboard material with a sufficient strength with respect to the recording and transmission of particular axially acting compressive forces and wound from a planar blank to a shell, as already well known. The blank is usually printed in its undeformed flat position and optionally provided with an additional coating. The material used is usually a cellulosic material, and this may also be a cardboard or strong paper produced in the recycling process. If a layer or layer of the outer part 3 is formed from a recycled material, an additional layer of a higher-quality paper can be arranged or connected to at least one of the surfaces. This additional layer is used for perfect printing for the production of ornaments, labels and product information.

The cuff-like outer part 3 leads to an additional reinforcement or stiffening effect of the inner container 2 and thus of the entire combination packaging container 1.

This is on the one hand a high strength and good thermal insulation and on the other hand, an optimal sunscreen for the content of the combination packaging container 1 given.

In this case, it may in particular also be provided that the cardboard is additionally coated or sealed in the region of the cut edges with a water-repellent material. This is particularly advantageous when the combination packaging container 1 an increased moisture content. are exposed to access. The coating of the cardboard used for the outer part with a water-repellent layer namely prevents it comes in a humid environment to swelling of the carton and finally to a detachment from the combination packaging container 1.

As a material for the cuff or jacket-like outer part 3, cardboard but also a plastic or an alternative plastic with biodegradable properties can be used. In particular, it is also possible to use a composite material which is made up of several layers of different materials, such as cardboard, plastic, but also metal foils. In the case of using a cardboard material is provided to provide the corresponding outer part 3 with a water-repellent layer. This can e.g. by using a laminated with a plastic film cardboard strip, which is tailored to take place. In this case, it may in particular also be provided that the cardboard is additionally coated or sealed in the region of the cut edges with a water-repellent material. This is particularly advantageous when the combination packaging container 1 are exposed to increased moisture access. The coating of the cardboard used for the outer part 3 with a water-repellent layer namely prevents it comes in a humid environment to a swelling of the carton and finally to a detachment from the combination packaging container 1.

The outer part 3 may be formed by a blank of a carrier material, such as paper or paper-like material, such as cardboard or corrugated cardboard, plastic, leather, fur, natural fibers, natural threads. The fibers and / or threads can be further processed into fabrics, braids, knitted fabrics, fleeces made of natural and / or synthetic materials. Naturally, natural fibers also include animal hair. However, it is also possible for the materials described above to be combined with one another as desired and / or also to be used in multiple layers.

In this case, the film film for the outer part 3 may be formed by at least one layer of plastic and / or lacquer and / or metal

It is advantageous if, in the ready-to-use state of the combination packaging container 1, the cardboard material of the outer sleeve part 3 is substantially in the Level and in the circumferential direction of the shell-like outer part oriented cellulose fibers, since in a possible moisture absorption of the cardboard material swelling of the fibers takes place in the radial direction and thus does not adversely affect the strength, as by an increase in the longitudinal direction and thus a possible slippage of the shell-like outer part of the packaging container is the case.

The cuff-like outer part 3 can in a preferred embodiment consist of a nonwoven. With a variety of fibers, the web has a significantly higher overall surface area per unit volume and can hold more insulating air. As a result, a high degree of cold or heat protection is achieved even at low material thicknesses. When using microfiber nonwovens, this effect is further enhanced. To achieve the desired strength values, the fibrous structure of a nonwoven requires only a small amount of material or a lower nonwoven thickness compared to paperboard materials.

The inner container 2 has a container jacket 4, a bottom 5 and, if appropriate, a flange 7 protruding outwardly beyond the container jacket 4 in the region of an open end 6. Through the cup or bowl-shaped design of the inner container 2 extends in

Axial direction between the open end 6 and the bottom 5 a longitudinal axis 8, which may also represent a central axis in symmetrical design. In the region of the flange 7, it is possible to arrange a sealing plate, not shown, or to connect to it.

In the axial direction and thus in the direction of the longitudinal axis 8, the inner container 2 between its open end 6, in particular the flange 7, and the bottom 5 a container height 9, whereby the receiving volume of the inner container 2 is determined depending on the cross-sectional dimensions. By the container height 9 in conjunction with the cross-sectional dimensions thus a receiving space 10 of the inner container 2 is defined.

The cuff-shaped outer part 3, which is arranged on the inner container 2 in the region of its container jacket 4, preferably surrounds the container jacket 4 to a predominant extent Share and points in the direction of the container height 9 spaced end portions 11, 12. In the present embodiment, the end portion 11 is the open end 6 of the inner container 2 and the other end portion 12 facing the bottom 5 or arranged adjacent.

As a container shell 4 that portion of the inner container 2 is understood, which extends between the open end 6, in particular the flange 7, and the bottom 5 in a predominantly axial direction. Preferably, the inner container 2 is formed with its container shell 4 such that it tapers conically starting from the open end 6 toward the bottom 5.

Furthermore, the container shell 4 of the inner container 2 in its bottom 5 adjacent peripheral portion on a rear train 13. The rear pull 13 is also part of the container jacket 4, but is arranged in an axial section with respect to an imaginary, straight-line connecting line between the flange 7 and the base 5, offset inwardly therefrom. The Hinterzug 13 in turn has at least two rear wall sections 14, 15, wherein the two Hinterzug wall sections 14, 15 seen in axial section with respect to the longitudinal axis 8 have a different inclination or direction than the rest of the container shell 4. It is the Hinterzug 13, opposite the seen in axial section, rectilinearly running arrangement of the container shell 4 between the flange 7 and the bottom 5 to the inside and thus arranged offset in the direction of the receiving space 10.

As seen in axial section, the first rear wall section 14, which adjoins the bottom 5 directly, is arranged or formed extending predominantly in the direction of the container height 9 toward the open end 6. The further rear wall section 15 extends in a predominantly vertical direction with respect to the container height 9, starting from the bottom 5 facing away from the end of the first Hinterzugwandabschnittes 14 towards the container shell 4. In the present embodiment, the further Hinterzugabschnitt 15 forms a stacking shoulder 16. This stacking shoulder serves to ensure that a similar combination packaging container 1 with its bottom 5, in particular the marginal transition section between the bottom 5 and the container shell 4, is supported thereon. Furthermore, the inner container 2 in the immediate transition region between the bottom 5 and the container shell 4, in particular between the bottom 5 and the rear pull 13, a projecting on the side facing away from the longitudinal axis 8 side 17 have shoulder. This shoulder 17 can serve, for example, to hold the cuff-shaped outer part 3 locked on the inner container 2. In this case, the cuff-shaped outer part 3 is supported with its the end 5 of the inner container 2 facing end portion 12 at this formed in the transition region shoulder 17 from. The shoulder 17 can thus also be referred to as a latching means for holding the outer part 3 on the inner container 2. A further latching means in the region of the open end 6 can be, for example, the flange 7.

To achieve a high support function and load transfer, it is advantageous if the cuff-shaped outer part 3 is supported with its first end portion 11 on the flange 7 or is arranged immediately adjacent thereto. Furthermore, the floor 5 facing, further end portion 12 of the outer part 3 is supported on the shoulder 17. Thus, the container shell 4 of the inner container 2 in this section is only the sealing function and must be designed so stable that attaching the blank or the already completed outer part 3 in the region of the container shell 4 is possible. A particularly high support function of the outer part 3 is achieved when viewed in axial section, between its two spaced apart in the direction of the container height 9 end portions 11, 12 is formed continuously straight.

Furthermore, it is shown here that the receiving space 10 of the inner container 2 is subdivided by at least one separate separating element 18 in the direction of the container height 9 into partial receiving spaces 19, 20 formed on both sides of the separating element 18. In this case, the separating element 18 with a receiving space 10 facing the shell part surface 21 of the first Hinterzug - Wandab section 14, if necessary, removably connected by the shell part surface 21 with this. By arranging and providing the separating element 18, it is thus possible first to completely produce the combined packaging container 1, then to fill in the receiving space 10 a filling material not shown in more detail and subsequently by attaching the separating element 18 to be able to stock the contents against external environmental conditions within the receiving space 10.

The separating element 18 may be formed from a wide variety of materials, in which case, for example, a sealing plate has proven to be favorable, which is introduced into the receiving space 10 after the filling of the receiving space 10 with the intended filling material and is preferably connected in a continuous manner to the casing part surface 21.

In the finished spatial form of the separating element 18, according to the exemplary embodiment shown, it may comprise, for example, a partition wall 22 oriented in a predominantly vertical direction with respect to the container height 9 and a connecting wall part 23 extending in the direction of the container height 9 on the outer circumference of the partition wall 22. The partition wall 22 and the connection s wall part 23 are formed by a one-piece component, which can be formed for example by a forming process. As a result of this forming process, the connecting wall part 23 can subsequently be connected to the casing part surface 21 of the first pull-out wall section 14.

Furthermore, the dividing wall 22 of the separating element 18 is arranged in the direction of the container height 9 of the inner container 2 at a distance from the stacking shoulder 16 of the rear draw 13 toward the bottom 9. As a result of this distancing in conjunction with the connection wall part, it is possible that the connection wall projecting upwards from the partition wall reaches the wall part of the separating element up to a maximum of the further rear wall section 15 forming the stack shoulder 16. Depending on the need and nature of the filling material, the connection between the separating element 18, in particular its connecting wall part 23, starting from a mere abut each other to reach as required releasable, but fixed mount. For the most part or preferably, the separating element 18, in particular its connecting wall part 23 circumferentially continuous with the casing part surface 21 of the first drawback wallab section 14 is connected so that the two part receiving spaces 19, 20 are sealed against each other. The term "mutually" or "sealed against one another" is understood here to mean that the two partial receiving spaces 19, 20 are liquid-tight and / or bacteria-proof and / or gastight separated by the separating element 18. As airtight airtight and / or acidic material can be tightly understood.

In order to be able to remove the separating element 18 from its concluding or sealing operating position, it can be provided with its own tear-off tongue 24, which extends from the separating element 18 towards the open end 6 of the inner container 2. This is shown schematically simplified in the right part of the combination packaging container 1.

The production of the combination packaging container 1 can be carried out, for example, as will now be described below. First, by deep drawing the cup-shaped inner container 2 with its container shell 4, its bottom 5 and optionally in the region of the open end 6, the container shell 4 outwardly projecting flange 7 is formed. In this case, the container shell 4 of the inner container 2 in its bottom 5 adjacent circumference sab cut is formed with the rear train 13 with the Hinterzugabschnitten 14,15. By this deep-drawing process, the inner container 2 is formed in axial section with the between the open end 6 and the bottom 5 extending container height 9, whereby the receiving space 10 is defined. Due to the own production of the inner container 2 in the deep-drawing process, the rear pull 13 described above can also be formed in the bottom region. This is, seen in axial section, thereby formed by the adjoining the bottom 5 first rear portion 14, which extends predominantly in the direction of the container height 9 toward the open end 6. The further Hinterzugabschnitt 15 is trained to form the stacking shoulder 16 in a predominantly vertical direction with respect to the container height 9 goes to the container shell 4. Subsequently, the inner container 2 is provided with the cuff-shaped outer part 3, which is arranged on the inner container 2 in the region of its container shell 4. Thus, the container shell 4 is surrounded to a predominant proportion. This surrounding can take place in such a way that the cuff-shaped outer part 3 is first produced from a blank by erecting and joining mutually facing end regions and then pushed onto the inner container 2. It would also be possible, the

Inner container 2, for example, to arrange on a mandrel and to wind the blank to form the cuff-shaped outer part 3 directly on the container shell 4 of the inner container 2 and then the facing each other and overlapping ends in one Overlap area to connect with each other. This is well known and will therefore not be discussed further. Likewise, however, the outer part 3 may also have a predefined set separation region in order to enable a corresponding separation into different materials, as is usual in the case of proper waste separation. This may be a tear strip, which may be provided for its operation with an actuating tab,

After production of the combination packaging container 1 and before the attachment of the separating element 18, the product to be stored in the receiving space 10 is introduced into it. These may be, for example, soluble substances or else freeze-dried material. Subsequent to this BefüUvorgang the separating element 18 is inserted into the receiving space 10 of the inner container 2, through which now the receiving space 10 in the direction of the container height 9 in both sides of the separating element 18 formed part receiving spaces 19, 20 is divided. In this case, the separating element 18 is connected to the receiving space 10 facing the shell part surface 21 of the first Hinterzug Wandab section 14. This connection is designed in such a way that the separating element 18 can be removed from the casing part surface 21 as required.

The separating element 18 can in turn be manufactured and formed differently. Thus, it would be possible, for example, to form the separating element 18 from a planar blank, in which the blank extends to a partition wall 22 oriented in a vertical direction with respect to the container height 9, and to that on the outer circumference of the dividing wall 22 in the direction of the container height 9 Connecting wall part 23 is formed.

The blank, which has already been shaped to form the separating element 18, is introduced into the receiving space 10 of the inner container 2 for the joining process with the casing part surface 21 of the first drawstrip wallab section 14 and then positioned. After positioning has taken place, the connection process with the casing part surface 21 of the first rear wall section 14 can be carried out, if so provided. The insertion or introduction of the deformed separating element 18 along the first drawstrip wallab section 14 towards the bottom 5 of the inner container 2 takes place until that of the partition wall 22 towering connection s wall part 23 of the separating element 18 to a maximum of the stacking shoulder 16 bil- denden further tail wall section 15 reaches. This ensures that the end edge of the peripheral connecting wall part 23 facing the open end 6 is arranged with a maximum planar extension with respect to the stacking shoulder 16 or its wall part of the rear strip 13. This ensures that the connecting wall part 23 does not project beyond the stacking shoulder 16 in the direction of the open end 6.

Regardless, it would also be possible that the blank is formed to form the separating element 18 before its deformation with a cross-sectional dimension, which is selected such that the blank wallab section 14 before the connection process with the middle part face 21 of the first draw the formed in the inner container 2 stacking shoulder 16 is placed and supported thereon. Subsequently, the forming and joining of the separating element 18 with the first drawback Wandab section 14. Thereafter, as is better seen in FIG. 3 can be seen, a stamp 25 is inserted into the receiving space 10 of the combination packaging container 1 and so far adjusted to the blank to form the separating element 18 that a bottom 5 facing the front end 26 of the punch 25 is located approximately at the level of the stacking shoulder 16. This results in the abutment of the front end 26 on the blank to form the separating element 18. In a further adjustment towards the bottom 5 that portion of the blank, which is supported on the stacking shoulder 16, towards the punch 25 formed, as this in the right part of Fig. 3 is shown. In this case, at least in the corner region of the punch 25, a heater 27 shown in simplified form may be provided, with which heat energy for carrying out the connection operation of the separating element 18 with the Man telteilfläche 21 is introduced. The bonding process is usually carried out by an adhesive or sealing process, in which at least the edge region of the separating element 18, in particular its connection swandteil 23, is coated with a heat-activatable bonding layer, in particular an adhesive layer. If the introduction and positioning operation of the separating element 18 in the region of the rear draw-off wall section 14 is completed, the heating of the stamp 25 by the heating device 27 can be started, for example. However, it would also be possible to actuate the heating device 27 during the forming process in order to prevent the heating time up. Zen. In this case, there is only the risk that softened adhesive material will be unintentionally removed during the insertion process of the separating element 18 from the section facing the casing part surface 21. If the bonding medium has solidified so far that the stamp 25 can be removed from its connection position or working position from the receiving space 10 again, this movement process is performed.

The attachment of the separating element 18 in the region of the rear wall section 14 set into the receiving space 10 has the advantage that, due to its very thin shape

Wall thicknesses of the inner container 2, there is no contact with the container shell 4 before reaching the working position, since there is an all-round continuous distancing of the punch 25 from the inside of the container shell 4. If a punch 25 is in operation, this would lead to damage and possible leakage in the event of direct contact with the container casing 4 of the inner container 2, which can only be assessed by the presence of the outer part 3 by inspection of the receiving space 10 and not by the outside is immediately recognizable.

By wrapping the inner container 2 with the outer part 3, access from the outside to the stacking shoulder 16 in the region of the rear pull 13 is no longer possible. Thus, a support of further Hinterzug wandab section for carrying out the connection process no longer occur.

FIG. 4 shows a further embodiment of the combined packaging container 1, which is possibly independent of itself, wherein the same reference numerals or component designations as in the preceding FIGS. 1 to 3 are again used for the same parts. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 3 or reference. This combination packaging container 1 shown here is basically the same design as that combination packaging container 1 according to FIGS. 1 to 3. In addition, it is shown here that the container casing 4 of the inner container 2 is arranged at least in sections distanced from the sleeve-shaped outer part 3 over the circumference is. Thus, points the combined packaging container 1 seen over the circumference sections on which the inner container 2 is arranged with its container shell 4 immediately adjacent or adjacent to an inner surface 28. Between these first sections further sections are provided, in which the container casing 4 of the inner container 2 is arranged at a distance from the inner surface 28 of the outer part 3. These distanced sections are shown in simplified form in FIG. 4. Depending on the length sers extension of the distancing of the container shell portion of the inner container 2 may be formed in the direction of the container height 9 between the container shell 4 of the inner container 2 and the cuff-shaped outer part 3 at least one extending in the direction of the container height 9 channel 29.

This channel 29 can be chosen such that it extends almost continuously between the two end regions 11, 12 of the outer part 3 and an inflow opening and a Abströmöffung in the region of the two end regions 11, 12 is formed. Thus, an even improved cooling effect between the container shell 4 and the outer part 3 can be achieved when a hot medium is filled in the receiving space 10. This makes it easier for the user to be able to hold the combined packaging container 1, despite the medium being filled with heat, without the outside of the outer part 3 assuming such a high temperature that proper holding is no longer possible. The length sers extension of the channel 29 and the channels 29 in the direction of the container height 9 can be chosen freely, wherein the channel 29 may extend only over a partial height of the container height 9. In this case, in the regions adjoining the channel 29 in the direction of the container height 9, in turn, a direct contact or adjacent arrangement of the container jacket 4 on the inner surface 28 of the outer part 3 can take place.

The receiving space 10 of the combination packaging container 1 serves to accommodate and thus for the storage of a wide variety of goods.

Depending on the intended use of the combination packaging container 1, this can be used for receiving or packaging foods, hygiene articles, toiletries, cleaning agents or

Serve detergents. The foods may be soluble products such as instant coffee powder, cocoa powder, dairy products such as milk and / or milk products, cream, juices, drinks of various kinds, foods, dry foods or liquid foods. act. These different goods can be filled in cold or hot condition. Depending on the type of packaging container to be taken up and packaged, it may also have the following packaging properties for the packaged products, such as aroma protection, impermeability to fats, opacity, UV protection or oxygen impermeability. Furthermore, the entire packaging container should also be heatable in an oven or the like and thus be formed as a total heat resistant tent. If, for example, hot drinks are filled, care must also be taken to ensure that the packaging as a whole can be easily touched or handled. An essential aspect of the entire packaging container is also that it is recyclable or compostable as a whole. For this purpose, the respective materials used should be selected according to these requirements.
