Description

The invention relates to a cuff-shaped outer part for creating a casing of a cup-shaped inner container for a combined packaging container, as described in paragraphs 1, 4, 8 and 12 of the claims.

A container for food products, such as dairy products and the like, which has a glass as well as a cuff, is known from DE 20 2004 015 374 U1. The glass, in turn, has a bottom surface and a side wall. The cuff surrounds at least a detail of the side wall of the glass. In its upper end zone, the glass has a ledge, which serves as a stop for the cuff. Under this ledge in the area of the side wall on the outside there are several profiling, which serve as retaining protrusions for the cuff. The side wall of the cup is conical with a narrowing from the open end to the bottom, while the cuff has a cylindrical shape, and, thus, the cuff blank in the expanded form has a substantially rectangular shape. For alignment between the cylindrical cuff and the conically tapering side wall, the cuff in the bottom zone is flanged and forms a large thickening.

DE 295 01 247 U1 describes a combination packaging of several materials, which are preferably selected from plastic and paper. The combination package contains a can arranged to be stacked by introducing the cans into each other, being in a wound cylinder, preferably made of paper. This cylinder is equipped in the bottom zone with a flange and rests on the side surface of the can lying inside. In its open end zone, the insertion can has a specially formed upper edge, which is used for sealing with a sealing disk. In addition, the combination package is preferably provided with a resealable plastic lid. Flanging rests on the smooth surface of the inwardly offset portion of the side surface of the insertion can.

DE 33 26 369 C2, respectively, EP 0 102 522 B1, describes a method for manufacturing a conical plastic container with an outwardly projecting edge of the hole by means of a deep drawing. The manufacture of this combined packaging container is carried out by placing a cuff in the shape of the deep drawing device, and then pulling the conical container inside the cuff. Thus, the elongated inner part is connected with a geometric closure with the outer part into a finished combined packaging container. In addition, the cuff has a folding inward, thereby closing the lower trim edge of the cuff, so that moisture cannot penetrate to it. In addition, the lower edge of the cuff is supported from below by a circumferential, radially outwardly protruding edge of the bottom part. This is ensured by the fact that the cuff is located in the corresponding axial position in the form for deep drawing. With deep drawing, a deeply drawn film is pressed tightly with compressed air to the inside of the cuff. The fixed connection between the plastic layer and the cuff can be further improved by elevations formed in the wall of the container. This elevation can additionally serve as an edge for stacking with several combined packaging containers located one above the other and pushed into each other.

CH 693 611 A5 also describes a combined packaging container with an outer casing pre-made from cardboard, respectively, of hard paper material and having an inner container 2 located therein by deep drawing. The pre-made outer casing is laid in a deep drawing mold, so that when deep drawn exhaust hood, the inner container is closely adjacent to the outer shell. In the bottom zone, the outer shell has a fold folded inward, which forms a bottom edge with the form of a thickening of the fold edge. The groove extruded in the cardboard folding material has two wall thickening containers protruding into the inner space. The inner container is pulled into the outer shell so deep that its thin wall, on the one hand, surrounds the edged edge of the fold and, on the other hand, passes over the area profiled by a groove with thickened walls. Due to the tight fit during deep drawing, a good connection is formed with a geometric closure with the outer shell, which counteracts the pulling of the inner container from the outer shell. The bottom wall of the inner container is located at a distance from the bottom edge of the container formed by folding, so that the folding part downward from the bottom wall forms an annular leg, respectively, a hollow bottom of the container.

EP 0 929 455 B1 describes a method for manufacturing a combined packaging container in which a cuff is pulled over an inner container. As an axial fixation, the inner container has in the area of its both ends spaced apart from one another an edge thickening on one side and a flange on the other. An outer part having the shape of the cuff passes between them and further rests on them. Due to this, in many cases it is impossible to transmit large stacking forces, since the holding edge on the bottom side is damaged due to the support of the outer cuff having the form of a cuff in the bottom zone of the container.

A combined packaging container with a removable shell-like outer part is known from EP 0 408 515 A. Moreover, the outer part has a strip of a predetermined compartment passing between its end zones in the direction of the longitudinal axis, which is located in the overlap zone of the two overlapped seams of the ends connected to each other. With the help of a gripping tongue, it is possible to capture the strip of a given compartment and thereby activate it, due to which the desired separation can occur, so that it is possible to remove, in most cases, from cardboard or paper material, the outer part from the inner container.

The basis of this invention is the task of increasing the intrinsic rigidity of the combined packaging capacity and at the same time reduce the cost of its manufacture. In addition, the consumption of expensive materials should be reduced. Additionally, the ability to separate the outer part from the cup-shaped inner container must be improved.

This objective of the invention is solved using the method with the characteristics of paragraph 1 of the claims. Moreover, it is preferable that individual parts for forming a combined packaging container, namely, a cup-shaped inner container and a cuff-shaped outer part, can be manufactured separately from each other, and only shortly before filling the cuff-shaped outer part is placed on the inner capacity. Due to this, increased flexibility and smaller stocks are achieved, since the cuff-shaped outer part can be simply connected in a predetermined quantity to the inner container depending on the product placed in the container. Due to the fact that the outer part having the form of the cuff is folded by its folding edge to the predetermined receiving space formed in the inner container, the open shaped edge in the bottom zone is excluded. In addition, the stability of the entire combined packaging container is also increased in this zone. Another advantage is that in this way the combined packaging container is completely covered over its entire height by the cuff-shaped outer part. This ensures, on the one hand, the optimal removal of the load emanating from the end of the inner container open in this case, by its flange on the outer part having the shape of the cuff, and, on the other hand, a uniform overall appearance. By setting the folded edge onto the abutment surface of the combined packaging container, the load transfer is carried out exclusively with the help of a cuff-shaped outer part. The inner container due to the introduction into the cuff-shaped outer part is supported on it. In addition to this, there is also no need for complicated mechanisms for holding the cuff-shaped outer part on the cup-shaped inner container. This reduces not only the cost of the tool, but also the cost of logistics.

Preferably, in the process steps selected in claim 2, a sufficient receiving space is created in advance for the folded edge. However, due to this, it is also possible to increase the strength of the entire combined packaging container in the area of its bottom.

In addition, a method with the features specified in paragraph 3 of the claims is preferable, since due to this, optimal transfer of force from the side surface of the inner container to the reinforced area of the cuff-shaped outer part is ensured with minimal means.

Preferred are the features of paragraph 4 of the claims, due to which a rectilinear, when viewed in longitudinal section of the combined packaging containers, the implementation of the cuff-shaped outer part.

The embodiment according to claim 5 or 6 is also preferable, since due to this, in the area of the folded edge, in particular its trimmed edge, a simple and easy process of connecting to the inner container and then fitting the trimmed edge to the cuff-shaped outer part . Due to this, a clamping action is achieved, and thus, it is possible to transmit higher stacking forces emanating from the flange through the cuff-shaped outer part to the supporting surface.

It is preferable in the steps of the method according to claim 7 that a predetermined stacking height is set in the bottom zone for subsequent separation, in order to facilitate, thereby, automatic processing, such as joining both structural elements. In addition, due to this, the circumferential strength of the inner container increases.

In addition, the features of claim 8 are preferable, since it is possible for the user to easily separate the cuff-shaped outer part from the inner container.

Other preferred features are indicated in paragraph 9 of the claims, which ensures that the cuff-shaped outer part is held in geometric closure on the inner container. Due to this, flawless mechanical locking is achieved without large additional costs.

An embodiment of the method according to claim 10 is preferable, since due to this, with the remaining constant structural height of the cuff-shaped outer part, it is possible to simply coordinate the receiving volume of the inner container with different filling volumes. In addition, the support of the bottom of the inner container on the supporting surface is prevented, thereby preventing damage when selected very thin walls.

In addition, the features of paragraph 11 of the claims are preferable, since due to this it is possible to refuse to place an additional stacking edge in the inner space of the inner container. Due to this, an internal container having almost flat surfaces is created, from which it is possible even more simply and, above all, to completely extract the product filling it. Due to this, the proportion of residues in the internal space is reduced, due to which the cleaning process for subsequent waste processing and reuse is also facilitated.

An advantage of the steps of the method according to claim 12 is that also in the area of the open end of the inner container, the open trimming edge of the folded edge can be closed and thereby prevent inadvertent detachment upon absorption of moisture. In addition, due to this, retention of the assembled individual parts is also achieved.

In addition, the features of claim 13 are preferable, as this results in even higher stability of the cuff-shaped outer part in the bottom zone. Due to this, the pressure forces emanating from the placed product are transmitted directly from the inner container to the outer part, which is rigid in the bottom zone, in the form of a cuff, in particular to its seamed edge.

In addition, the features of claim 14 are preferable, as this eliminates additional processing steps to form a cuff-shaped outer part, and furthermore, the appearance of the printed image is substantially improved. In addition to this, a very high intrinsic strength is provided and, thereby, the possibility of transmitting large pressure forces is created.

In addition, the features of paragraph 15 of the claims are preferable, since due to this the wall thickness of the inner container may be even smaller, and the sole detail of the cuff-shaped outer part performs the function of supporting the entire combined packaging container.

In addition, the features of claim 16 are preferable, since due to this, despite the detachable connection, a stable combined packaging container is created for receiving a wide variety of filling products.

Another preferred embodiment of the method is described in paragraph 17 of the claims, because due to this, up to the connection with the internal capacity there is a flat workpiece. It is not only easy to print on, but also requires minimal storage space.

Other preferred steps of the method are indicated in paragraphs 18-21 of the claims, since due to this, it is possible to perform a simple separation of the cuff-shaped outer part from the inner container. This ensures a flawless recyclability.

Other preferred steps of the method are indicated in paragraphs 22 and 23 of the claims, since this provides the simple possibility of separating the cuff-shaped outer part from the inner container. In addition, it is also possible to separate the cuff-shaped outer part in the area of the reinforced fold edge without additional damage to the outer part.

Another preferred step of the method is indicated in paragraph 24 of the claims, because this allows the user to easily perform separation from the end located on the bottom side.

Also preferred is an embodiment of the method according to paragraph 25 of the claims, since this creates not only a certain protection of originality, but also provides the possibility of fixing the entire shaped cuff of the outer part on the inner container.

An advantage of the process steps selected in paragraph 26 is that the separation is much easier for the user. In addition, due to this, the manufacture of the inner container is also facilitated, since the gripping chamber located in the open end area of the inner container would create problems when removing it from the mold.

In addition, the features indicated in paragraph 27 of the claims are also preferred, since due to this, despite the large supporting pressure, it is possible to make the inner container airtight with the help of a cuff-shaped outer part with minimal material costs.

However, the objective of the invention is solved independently also using the features of paragraph 28 of the claims. The advantages arising from the combination of features of this claim are that a combined packaging container is created, the total mass of which is predominantly formed from the mass of the cuff-shaped outer part. If it is made of paper or cardboard material, then in this case, it can be easily recycled. Due to the fact that the cuff-shaped outer part fulfills the entire supporting function of the combined packaging container, it is possible to use even less material, in particular plastic, to form the inner container. Thus, the cost can be greatly reduced, and local resources can be used to create the cuff-shaped outer part.

However, the objective of the invention is solved independently also using the features of paragraph 29 of the claims. The advantages arising from the combination of features of this claim are that it is possible to create a workpiece, respectively obtained from it, in the form of a cuff, respectively, of a shell, an outer part in which there is a stable overlapping zone and, nevertheless, there is the possibility of removing the outer part held in most cases with a geometric closure on the internal container for separate disposal. Due to the plurality of tear-off strips arranged with a distribution around the circumference and made as a zone of a predetermined separation, it is possible to increase the circumferential size of the cuff-shaped outer part by separating the tear-off strips at the end facing the bottom of the combined packaging container so that its simple removal is possible. Due to the fact that the tear-off strip or tear-off strips pass only along the height part of the outer part, it remains in the form of a closed shell after the tearing and also removing process, which is only partially separated, starting from the bottom zone. The shorter the tear strip is torn, the longer the undamaged portion of the outer part remains.

It is also possible to perform according to paragraph 30 of the claims, since this prevents lateral forces and, thus, during the tearing process, the outer part is pressed in the direction of the flange, due to which it is also possible to apply large forces for the tearing process.

Another preferred embodiment is indicated in paragraph 31 of the claims, since this makes handling the tear strip easier. In this case, the tear-off tab may be an integrated component of the tear-off strip, or it may represent a separate structural element connected to it.

It is also possible to perform according to paragraph 32 of the claims, since this provides the possibility of accurately initiating the tearing motion.

However, the objective of the invention is solved independently also using the features of paragraph 33 of the claims. The advantages arising from the combination of features of this claim are that due to this, the immediately adjacent overlap zone in connection with the separation zone defines a detachment plane, respectively, of separation. Due to the fact that along the overlapping and lying outside the longitudinal side, respectively, of the longitudinal edge of the workpiece, a separation zone is formed, the overlap zone can also be used as an actuating means for disconnecting, respectively, separating the cuff-shaped outer part. Since the separation zone is further provided with actuating means between both end zones, separation is further facilitated, and tearing motion is set and reliably performed depending on the location of the actuating means.

It is also possible to carry out in accordance with paragraph 34 of the claims, since due to the cutout thus arranged, it is easier to grip the longitudinal side of the overlaid end. Due to this cut-out, which passes completely through the wall thickness of the workpiece, respectively, of the outer part formed from it, it is possible, starting from it, to disconnect along a predetermined separation plane easier and more reliably.

It is also possible to perform in accordance with paragraph 35 of the claims, as this additionally facilitates the capture of the overlapping end.

Another preferred embodiment is described in paragraph 36 of the claims, because it creates an actuator that is easy to grab, and thereby further facilitates the process of disconnecting, respectively, the separation of the cuff-shaped outer part.

It is also preferable to perform in accordance with paragraph 37 of the claims, since it is possible to uniformly separate the outer part along the entire longitudinal extent with the help of the Central point of capture.

However, the objective of the invention is solved independently also using the features of paragraph 38 of the claims. The advantages arising from the combination of features of this claim are that it is possible to separate the outer part from the inner container, in which segments of the lateral surface of the outer part remain intact without damage due to rupture, and yet it is possible to disconnect the outer part from the inner container for subsequent separation.

The preferred modification is indicated in paragraph 39 of the claims, since it is possible to maintain an almost constant height outer part, which, despite being connected along the perimeter, can be separated from the inner container. Thus, it is possible to provide several separated external parts as structural elements, in particular to children.

Finally, the embodiment indicated in claim 40 is also preferred since the tearing motion can be increased and thereby the tearing accuracy can be increased.

The position indications selected in the description, such as, for example, from above, from below, from the side, etc., refer to the directly described and depicted figure and are subject to transfer in meaning when changing position to a new position. In addition, individual features or combinations of features from the illustrated and described exemplary embodiments may themselves constitute independent inventive or inventive solutions.

All indications of ranges of values in the subject description should be understood so that they contain any and all of its partial ranges, for example, indication 1-10 should be understood so that all partial ranges are included, starting from lower boundary 1 to upper boundary 10, i.e. . all partial ranges begin at the lower boundary of 1 or more and end at the upper boundary of 10 or lower, for example, 1–1.7 or 3.2–8.1 or 5.5–10.

In FIG. 1-3, a combined packaging container 1 is shown in a simplified form, which in this embodiment contains a cup-shaped inner container 2, in particular of plastic material, as well as an outer part 3 having a cuff-shaped surrounding container 2. The inner container 2 can be made of any plastic materials, but also, respectively, of other highly extractive, biodegradable materials.

The inner container 3 contains in the direction of its longitudinal axis 4 an open end 5, as well as a closed end 6, located at a distance from each other. The filled space 7 of the inner container 2 is limited by the side surface 8 of the container, as well as the bottom 9, and can serve to accommodate various dishes, dairy products, etc. In addition, the inner container 2 may have a flange 10 protruding outward beyond the side surface 8 of the container in the region of its open end 5. This flange 10 is preferably located around the entire outer perimeter of the inner container 2 and is used in most cases also as a sealing flange for sealing and, thereby closing the filling space 7 from the effects of external environmental conditions after filling.

The cuff-shaped outer part 3 surrounds in its wound, respectively assembled state, the inner container 2 in the region of its side surface 8 and closes it around the circumference, preferably completely.

The combined packaging container 1 shown in this case is designed so that the inner container 2 is manufactured separately from the cuff-shaped outer part 3, and both structural elements are stored, respectively, processed separately from each other until the final installation, before the connection process. Due to this, it is possible to produce uniform inner containers 2 for various filling products, and only shortly before filling or after filling, to connect the cuff-shaped outer part 3 with the inner container. If the outer part is installed, respectively, is rolled into a shell and assembled as a structural element, then it can be pushed onto the inner container 2, respectively, the inner container 2 can be inserted into the cuff-shaped outer part 3. Regardless, it is also possible to form the outer part 3 to turn the workpiece directly onto the inner container 2 stretched on the mandrel, and then connect it to the outer part 3. Only due to this process a combined packaging container 1 is formed. s small wall thickness of the inner container 2, such containers may be manufactured separately from the outer parts 3, however, already before filling merge together in a combination packaging container 1.

Regardless of this, it is also possible to first create a cuff-shaped outer part 3 from the workpiece, and then lay it before forming the inner container 2 in a shape not shown for deep drawing, and only then begin to deform the film intended for deep drawing. This method is then called in-line production. Thus, a ready-made combined packaging container 1 is obtained immediately, which can then be filled without additional installation costs in order to connect the inner container 2 and the cuff-shaped outer part 3.

In addition, it is also shown here that in the direct transition zone 11, starting from the bottom 9, to the side surface 8 of the container, a wall section 12 displaced relative to the side surface 8 of the container is molded inwardly against the side surface 8 of the container to form a circumferential receiving space 13. With abutment to the inwardly displaced section of the wall 12, when viewed in a longitudinal section, respectively, an axial section of the inner container 2 relative to the longitudinal axis 4, a translating, respectively, guiding to the side surface 8 is formed mkosti ledge 14. This ledge 14 is located in most cases oriented perpendicular to longitudinal axis 4, and forms a plane directed outwardly with respect to the filling space 7 step.

In the inner container 2 made in the form of a cup in this case, the side surface 8 of the container and / or the wall portion 12 displaced inward relative to the longitudinal axis 4 of the internal container 2 are made with conical narrowing, starting from the open end 5 to the bottom 9. In this case, the taper of the side surface 8 containers it is preferable to choose different from the taper of the inwardly displaced portion of the wall 12. Preferably, the taper of the side surface 8 of the container is selected less than the taper of the inwardly displaced wall portion 12. This means that the inwardly displaced portion 12 of the wall, when viewed in a longitudinal section relative to the longitudinal axis, tapers more toward the bottom 9.

Immediately behind the ledge 14 extending to the side surface 8 of the container, respectively, protruding outwardly, the inner container 2 has an adjacent to it, when viewed in longitudinal section, from the opposite side wall section 12 displaced inwardly relative to the side side surface 8 of the container, the retracted section 15 having the opposite taper to form an edge 16 for stacking. In addition, in the zone of the inwardly displaced portion 12 of the wall of the inner container 2, a gripping chamber 17 can be arranged, respectively, schematically depicted in a simplified form in the lower left area of FIG. 1. The use and meaning of this gripping chamber 17 will be explained in more detail below.

As follows from the comparison of Figs. 1 and 2, the cuff-shaped outer part 3 has, in the region of the inner container 2 of the bottom container 9 of the end zone 18, a folded edge 19, preferably folded inwardly, 19. This folded folded edge 19 can be made by folding a portion of the cuff-shaped of the outer part 3, it being preferable if the folded edge 19 abuts continuously around the entire circumference of the cuff-shaped outer part 3. Thus, the folded edge 19 is an integral part for forming the outer part 3. In order to achieve additional stability of the outer part 3, it is preferable if the seamed edge 19 is connected, in particular in some areas, glued to the wall of the cuff-shaped outer part 3.

Regardless of this, it is also possible to form a folded edge 19 with the help of an own structural element independent of the workpiece and to connect it to the outer part 3 for the purpose of reinforcement. Due to this, it is possible to provide large differences in thickness between the outer part 3 and the folded edge 19.

As indicated above, the inwardly displaced portion of the wall 12 forms a receiving space 13 in which the folded edge 19 is placed when the outer part and the inner container are inserted into each other, and thereby form a combined packaging container 1. Relative to the longitudinal axis 4, having a cuff shape the outer part 3 has a structural height 20, which at least corresponds to the distance 21 between the flange 10, in particular, its lower side facing the bottom 9, and the bottom side 22 of the bottom 9.

Due to this, the supporting forces, respectively, the stacking forces, which act on the combined packaging container 1 in the direction of the longitudinal axis 4 in the area of the flange 10, can be transmitted directly from the flange 10 through the cuff-shaped outer part 3 to the simplified depicted supporting surface 23 of the combined packaging container 1. Thus, it is possible to do with the minimum wall thickness for the formation of the side surface 8 of the container, respectively, also the bottom 9. In this case, the transfer of supporting forces occurs eliminates flax, proceeding from the flange 10 via the sleeve-shaped outer part 3 and its end area 18 on the supporting surface 23. In order to achieve sufficient tightness lateral surface 8 of the receptacle and the bottom 9 must have a sufficient wall thickness to fulfill these requirements. However, it should also take into account the diffusion properties, respectively, the passage of gases, respectively, of water vapor through the material of the inner tank 2.

As already mentioned above, for the formation of the receiving space 13 provides an inwardly displaced portion of the wall 12. The wall portion 12 of the side surface 8 of the container, when viewed in longitudinal section of the inner container 2, is offset on each side by at least 24 inwards in the direction of the longitudinal axis 4, while 24 corresponds to at least a thickness of 25 edges 19. With appropriate small selected tolerances, it is possible to achieve here not only a certain clamping action between the cuff-shaped outer part 3 and the inner container 2, but also additionally a corresponding increase in the transition zone 11 about 9 to the bottom side surface 8 of the receptacle.

In addition, it is also possible that the circumferential edge 26 of the folded edge 19, facing the open end of the inner container 2, when viewed in longitudinal section of the inner container 2, abuts the protrusion 14, passing from the inwardly displaced portion of the wall 12 to the side surface 8 of the container. Due to this, additional support and stiffening of the side surface 8 of the tank in this section 12 of the wall. Thus, the pressure force of the mass of the filling product on the bottom side is introduced through the side surface 8 of the container directly into the cuff-shaped outer part.

In addition, it may be preferable, as shown in FIG. 2, if a groove 27 extending into the counter-conical section 15 is formed on the cuff-shaped outer part 3 in the region of the opposite taper, respectively. a mechanical connection for holding the cuff-shaped outer part 3 on the inner container 2.

In addition, FIG. 2 schematically shows in simplified form using dashed lines that the structural height 20 of the cuff-shaped outer part 3 relative to the inner container 2 is selected so that the bottom 9 of the inner container 2 is closed facing it, located on the bottom side of the end zone 18 of the cuff-shaped outer part 3. Thus, the structural height 20 of the cuff-shaped outer part 3 is selected greater than the distance 21 between the lower edge of the flange 100 and the lower side of the bottom 9, as has already been explained above with reference to to figure 1.

Due to this protrusion of the cuff-shaped outer part 3, in particular due to its folded edge 19, the bottom 9 is spaced apart from the supporting surface 23 and, thus, the circumferential support of the combined packaging container 1 on the folded outer part 3. Due to the support of the bent section of the folded edge 19 on the supporting surface 23, it is possible to print on the cuff-shaped outer part 3 over the entire surface up to the supporting surface 23, respectively, of the bottom 9, and due to this it is possible to provide more its high strength and rigidity of the entire combination packaging container 1.

If we further increase the protrusion of the cuff-shaped outer part 3 behind the bottom 9, shown in dashed lines, in the area of its folded edge 19, then, if necessary, we can refuse to arrange, respectively, the formation of the stacking edge 16. In this case, the support for stacking the combined packaging containers 1 can be carried out by supporting the protruding folded edge 19 of the first cuff-shaped outer part 13 on the step 14 of the other inner container 2 extending outwardly from the inwardly displaced wall portion 12.

Figure 3 shows in simplified form an additional possible embodiment of the cuff-shaped outer part 3 in its upper end zone 28 facing the flange 10.

In this case, the cuff-shaped outer part 3 has another, additional folded edge 29, which can be made similar to the above-folded edge 19. The folded edge 29 is also preferably folded inward, due to which the outer cuff-shaped outer cuff is facing details 3 there are no additional interfering edges. In this case, it is possible to carry out the folded edge 29 not along the entire circumference of the outer part 23, but only in some areas. To receive the folded fold edge 29, the side surface 8 of the container has an additional inwardly displaced wall portion 30, which forms a receiving space 31 for the folded edge 29. However, you can also just bend the other folded edge 29 and refuse to arrange the inwardly displaced wall portion 30 and the resulting another receiving space 31. When removing the inner container 2 from the mold, the inwardly displaced portion of the wall 30 located in the zone of the flange 10 can create problems, since the outer An inwardly protruding edge forms in the shape of the tool. However, this can be counteracted due to the taper of the side surface 8 of the tank.

When connecting the cuff-shaped outer part 3 to the inner container 2, the other folded edge 29, together with the outer part 3, slides in the direction of the flange 10 until this folded edge 29 pops into the receiving space 31 provided for it in the open end area 5 of the inner containers 2. Due to this, mechanical fixation of the cuff-shaped outer part 3 on the inner container 2 is achieved. This other folded edge 29 also preferably abuts laterally when bent around the entire perimeter Accordingly, the wall of the cuff-shaped outer part 3, as indicated above for the first folded edge 19. However, independently of this, it is also possible, instead of the inwardly displaced portion of the wall 30, to provide outwardly protruding locking protrusions that serve to fix the other folded edge 29 on side surface 8 of the tank.

In addition, it is also possible to divide the upper seamed edge 29 circumferentially into several sections 29 ″ of the seamed edge. If there are several sections 29 of the folded edge, they can be alternately folded, respectively, flanged in the circumferential direction and / or deformed outward under the flange 10, as shown in simplified form by dashed lines. If only individual sections 29 of the folded edge are deformed outward, then in this case, the wall portion 30 displaced inwardly can be discarded. In this case, it is preferable, accordingly, to take into account that the end zone 29 of the cuff-shaped outer part 3 facing the flange 10 is adjacent to the flange 10 and, thus, a continuous input of forces into the outer part 3 is ensured.

In addition, in order to achieve sufficient support and transfer of forces, it is preferable if the cuff-shaped outer part 3 with its inner surface 32 fits snugly on the outside to the side surface 8 of the container. Due to this, not only sufficient adhesion between these two structural elements is ensured, but also there is an optimal transfer around the entire circumference of the forces emanating from the filling product to the cuff-shaped outer part 3.

An even better load-bearing capacity of the combined packaging container 1 is achieved when the cuff-shaped outer part 3 is connected by means of easily exfoliating gluing, preferably over the entire surface, to the side surface 8 of the inner container 2. By “easily exfoliating” or “gluing” is meant connecting means between two facing each other surfaces, which provides sufficient retention, however, for the process of separating the outer part 3 from the inner tank Ty 2 easily disconnects without destroying structural elements. This ensures not only sufficient grip during the entire use of the combined packaging container 1, but also an additional flawless separation of the cuff-shaped outer part 3 from the inner container 2, as will be explained in detail below.

Figure 4 shows the cuff-shaped outer part 3 before pushing into each other with the cup-shaped inner container 2, respectively, to be formed in it by the inner container 2. Before that, it has already been rolled flat blanks into the shell. By folding the flat blank, the ends 33, 34 facing each other are then connected to each other in the overlap zone 35 shown in a simplified form. This is done using a so-called lap seam. In this case, folding as well as joining of both ends 33, 34 can be carried out, for example, by gluing, as is already widely known in the prior art. In this regard, the content of EP 0 408 515 B1 is taken into account in this description.

In addition, it is also shown here in a simplified form that, at least on one longitudinal side 36, 37 of the overlap zone 35 in the cuff-shaped outer part 3, respectively, a material attenuation is formed, such as an incision, a groove or shown in perforation 38. The attenuation of the material, such as perforation 38, is indicated by short angular strokes, but it can also be located, respectively, formed directly in the overlap zone 35. The aforementioned perforation 38 serves to separate the cuff-shaped outer part 3. In order to enable this opening movement to be more easily performed, a tear-off tongue 39 can be arranged respectively in the overlap area 35. In the embodiment shown here, the tear-off tongue 39 is turned to the bottom of the inner container 2. Due to this, the user can press the entire combined packaging container 1, starting from its open end 5, to the supporting surface 23 and then using the tear-off the tongue 39 to begin the separation process and at the same time break the perforation 38, with the aim of the subsequent separation of the cuff-shaped outer part 3 from the inner container 2.

To facilitate the capture of the tear-off tongue 39, the gripping chamber 17 shown in a simplified form in FIG. 1 can serve, in this case, only the corresponding relative orientation, respectively, overlapping position when connecting, respectively, sliding into each other inner container 2 and having the shape cuffs of the outer part 3.

However, with the structural elements introduced into each other, it is still possible to make the gripping chamber 17 in the larger circumferential zone as compared with the circumferential length of the tear-off tongue 39, in order to create a certain tolerance with mutual orientation before connection.

If the capture chamber 17 is made in the form of a recess extending around the circumference, then there is no longer a need for the mutual orientation of both structural elements when sliding into each other.

For the formation of the tear tab 39 in the overlay zone 35, it is preferable if, at least in the area of one of the longitudinal sides 36, 37 of the overlap zone 35, respectively, material attenuation and / or material dissection 40 is provided. An embossed line, a notch, a groove can serve as a weakening of the material, and a cut, a notch, or the like can serve as a dissection of the material 40. The dissection of the material 40 preferably takes place in the direction of the longitudinal side 36, 37 and can also penetrate the still lying and bent folded edge 19 of the outer part 3, or material weakening can be located there. However, preferably, the material cut 40 is aligned with both longitudinal sides 36, 37. Due to this, both longitudinal sides 36, 37 can serve as a tear-off zone.

The tear tab 39 can be formed either only from a portion of the overlap zone 35 lying closer to the inner container 2, or only from a portion of the overlap zone 35 remote from the inner container 2. However, it is also possible that the tear tab 39 includes both overlapping portions of the overlap zone 35 and, thus, has a double wall thickness. By bending the folded edge 19, the overall thickness of the tear-off tongue 39 is further increased. To prevent, accordingly, reduce this, it is possible to remove parts of the overlap zone 35 in the region of the tear-off tongue 39. This can be done already in a flat blank or only during the manufacturing of the outer part 3. Thus thus, the tear-off tab 39 is a component of the overlap zone 35, respectively, formed by this strip 45 of a given compartment, respectively, of the tear, which in this case extends over the entire height of the bunk the female part 3 in the direction of the longitudinal axis 4.

Since the tear tab 39 is oriented to the bottom 9 of the inner container 2 in the embodiment shown here, material divisions 40 also face the bottom.

To prevent unintentional separation, as well as to ensure the retention of the cuff-shaped outer part 3 on the inner container 2, a section separated by cutting material 40 in the overlap zone 35, such as, for example, the tear-off tab 39, can be connected using connecting means, such as glue, with an internal container 2. This can be done using a simplified gluing point 41, which, on the one hand, motionlessly fixes the tear tab 39 relative to the inner container 2 and, on the other hand s, subsequently also holds motionless the entire outer part 3 in its position on the inner container 2. Another gluing point 41 is also shown in the upper end region 28 of the outer part 3. It should also be noted that the placement of at least one connecting zone, such as gluing point 41, can be carried out over the entire area of the overlap zone 35 and selected arbitrarily.

Figure 5 shows another possible and, if necessary, independent embodiment of the cuff-shaped outer part 3, while again the same parts are denoted by the same positions as in the previous figures. 1–4. To avoid unnecessary repetitions, reference is made to the detailed description in relation to the previous FIGS. 1–4.

In this exemplary embodiment shown here, a cuff-shaped outer part 3 is formed from a blank that is connected in the region of its ends 33, 34 facing each other in the overlap zone 35. In addition, the workpiece can be folded along the bend lines 42, 43 and stored in a flat form until connected to the inner container 2, or rolled up into the outer part 3 and laid in a deep drawing mold for continuous production. The tear tab 39 can also face the bottom 9 of the inner container 2.

However, regardless of this, it is also possible that the tear-off tab 39 with material cuts 40 is located in the area of the flange 10 of the inner container 2 on the cuff-shaped outer part 3. In addition, both in the bottom area 9 and in the area of the flange 10 can be located, accordingly, it is provided for by the corresponding tear-off tongue 39, in order to enable separation from just one end zone 18, 28, or the separation of the outer part 3 from the inner container 2 from two sides.

Fig. 6 shows another possible and, if necessary, independent embodiment of the cuff-shaped outer part 3, respectively, its blank, and again the same parts are denoted by the same positions as in the previous ones. 1–5. To eliminate unnecessary repetitions, reference is made to the detailed description in relation to the previous FIGS. 1–5.

In the blank, flat and folded for the formation of the cuff-shaped outer part 3, in this case, in contrast to the exemplary embodiment shown in FIG. 5, the overlap zone 35 is located in its edge zone. In this exemplary embodiment, the fold line 42 simultaneously forms a boundary line 44 of the overlap zone 35. In addition, the overlap zone 35 is bounded on the other longitudinal side 37 by the indicated perforation 38. Thus, a flat outer part 3, lying for storage up to the connection with the inner container 2 or laying in the form for deep drawing, is again created, which only needs to be rolled up for the connection process and push. Due to the flat blank for the cuff-shaped outer part 3, printing on it and its external design is also greatly simplified.

In addition, it is preferable if the cuff-shaped outer part 3 has its own weight, which is at least 50% relative to the total mass of the combined packaging container 1. Due to the fact that the cuff-shaped outer part 2 is made of paper or cardboard material with different mass per unit area, it is thereby possible to constantly reduce the fraction of the material of the inner container 2. In particular, if the cuff-shaped outer part 3 extends completely rectilinearly between the flange 10 and the abutment surface 23 of the combined packaging container 1, since thereby achieving high intrinsic stability of the combined packaging container 1. Thus, large stacking forces can be transmitted.

Fig. 7 shows another possible and, if necessary, independent embodiment of the cuff-shaped outer part 3 in its folded position, and again the same parts are denoted by the same positions as in the previous ones. 1-6. To eliminate unnecessary repetitions, reference is made to the detailed description in relation to the previous FIGS. 1-6.

In this exemplary embodiment shown, a rolled-up blank is shown to form a cuff-shaped outer part 3 with its overlap zone 35. The two ends 33, 34 facing each other with their longitudinal sides 36, 37 form in this case only the connection zone of the workpiece to form the outer part 3 having a cuff-shaped cuff. Moreover, in general, as an external part, a structural element made in the form of a pipe is understood, the spatial shape of which can be from cylindrical to conical. In this case, the rolled up and connected workpiece forms an outer part 3, which, when viewed in the circumferential direction, forms a shell passing between the end zones 18, 28 located at a distance from each other in the direction of the longitudinal axis 4. In this shell, respectively, the side zone the surface should be provided, respectively, formed at least one zone of a given compartment, while the following figures show its various implementation, the description of which is given below.

To ensure, however, the possibility of separating the outer part after use from the inner container 2, in this case, at least one, however preferably several located with a distribution along the lower end zone 18 and extending to the upper end zone 28, is provided the circumference of the tear-off strips 45. The tear-off stripe or tear-off strips 45 extend only along the partial height 46 of the outer part 3 between its two end zones 18, 28, preferably with a parallel orientation with respect to the native axis 4. Due to the fact that the tear strip or strips 45 are oriented to the bottom 9 of the inner container 2, respectively, extend from it, the circumferential dimension in the lower end zone 18 can be increased so that it is easy to remove the outer part 3 with internal capacity 2. With several tear-off strips 45 arranged with a circular distribution, it is possible to achieve even greater instability after partial separation of the outer part 3, in order to remove the retained in most cases with a geometrical closure we eat on the inner container 2 of the outer part 3. This is achieved when the end zone 18 of the outer part 3 facing the bottom 9 is supported from below by a protrusion protruding radially outwardly from it, and thereby, in conjunction with the conical embodiment as the inner container 2, and the outer part 3 is a mutual fixation of the position of both structural elements. To facilitate the separation of the tear-off strip 45, it can be provided with a tear-off tongue 39, respectively, part of the tear-off strip 45 can be formed by the tear-off tongue 39. To form the tear-off strip 45 in the material for forming the outer part 3, the aforementioned material attenuation can be located, in particular oriented in the form of angles perforation 38, in order to facilitate separation of the outer part 3 along predetermined separation lines. Thus, weakening of the material limits the tear strip 45 from the sides along its width along its entire longitudinal extent.

For the formation of the tear-off tongue 39, it may be preferable if, starting from the lower end zone 18, a material cut 40 is formed in a partial portion of a partial height 46, in order to facilitate the actuation, respectively, of using the tear-off tongue 39. Thus, the cut of material 40 interrupts connection with the remaining lateral surface of the outer part 3. Due to this, it can be easily folded radially outward and then the tear strip 45 can be separated along the weakening of the material, respectively, the perforation and 38.

Since the blank of the outer part 3 always remains glued in its overlap zone 35, and the tear strip or strips 45 extend only at a partial height 46 of the total height of the outer part 3 in the direction of its longitudinal axis 4, the outer part 3 retains its basic shape, while only due to the partial separation of the circumferential zone facing the bottom 9, the stability is reduced so much that it can be easily removed from the inner container 2. In addition, on the inner side of the outer part 3, you can provide e the fold edge 19, which eliminates the open edge shaped outer part 3 when necessary.

Figs. 8 and 9 show another possible and, if necessary, independent embodiment of the cuff-shaped outer part 3 in its circumferentially connected as well as folded position, with the same parts again being denoted by the same positions as in the previous ones. 1-7. To eliminate unnecessary repetitions, reference is made to the detailed description in relation to the previous FIGS. 1-7.

The blank is connected at its ends 33, 34 with the formation of an overlap zone 35 in a peripheral structural element, i.e. a cuff-shaped outer part 3. Opposite the inner container 2, as well as the overlapping end 33 lying, the outside lying end 34 forms a dividing zone 47 with its longitudinal side 37 in the direction of the longitudinal axis 4. In this dividing zone 47, one or more weakenings can again be provided material, in particular, perforation 38. Approximately in the middle relative to the total height of the outer part 3 in the direction of its longitudinal axis 4 in the adjacent section of the wall 35 of the overlap of the wall of the outer part 3 is located at least one cutout 48, which extends over the entire thickness 49 of the wall of the workpiece, respectively, of the outer part 3.

In addition, Fig. 9 schematically shows that with the help of the finger 50, in particular the thumb, it is possible, due to the lack of material of the outer part 3 in the area of the cutout 48, to grasp the longitudinal side 37 of the outer end 34, and thereby, starting from cutout 48, to separate by pulling formed on both sides of the separation zone 47 of the perforation 38.

The grip of the longitudinal side 37 can be further improved if the cutout 48 comes in a circumferential direction into the overlap zone 35 and thereby facilitates the capture from below of the wall part. Thus, as if there is again a tear-off tab 39. Thereby, the cutout 48, if necessary in combination with the tear-off tab 39 forms an actuating means.

Figure 10 shows another possible and, if necessary, independent embodiment of the cuff-shaped outer part 3 in the overlap connected in the overlap zone 35 as well as in the flat-folded position, and again the same parts are denoted by the same positions as in the previous figures. 1–9. To eliminate unnecessary repetitions, reference is made to the detailed description in relation to the previous FIGS. 1–9.

Since this embodiment is very similar to the embodiment shown in FIGS. 8 and 9, only the differences between them are explained in detail here.

Instead of the cutout 48 indicated above, in this case, a tear tab 39 is formed in the outer part 3 according to the window of the Christmas calendar, in which the tear tab 39 can be turned outward along the weakening line U-shaped 51. On both sides of the tear tab 39 towards both end zones 18, 28, a separation zone 47 is again formed along the longitudinal side 37 of the end 34. This separation zone 47 may also have several material weakenings, such as, for example, perforation 38.

If it is necessary to separate the entire outer part 3 from the inner container 2, it is first necessary to separate the tear tab 39 along the line 51 of weakening. Since the weakening line 51 ends in the region of the longitudinal side 37 of the end 34, the opening force when actuating the tear tab 39 is directed to the separation zones 47 located on both sides and separates the outer part 3 along the perforation 38. Both ends 33, 34 facing each other outer parts 3 are again fixedly connected to each other.

In the FIGS. 8 and 9, as well as in the 10 embodiments, no separate tear strip 47 is formed, and the cuff-shaped outer part 3 is separated along the separation zone 47. This separation zone 47 is preferably oriented parallel to the longitudinal axis 4 and runs straight between both end zones 18, 28. In this case, actuating means, such as cutout 48 and / or tear-off tongue 39, are located approximately in the middle between both end ends spaced apart from each other in the direction of the longitudinal axis us 18, 28.

11 shows another possible and, if necessary, independent embodiment of a cuff-shaped outer part 3 in the form of a connected blank in a flat folded position, with the same parts again being denoted by the same positions as in the previous FIG. 1-10. To eliminate unnecessary repetitions, reference is made to the detailed description in relation to the previous FIGS. 1-10.

In the outer part 3 shown here, the ends 33, 34 facing each other are also connected to each other in the overlap zone 25 in the form of an overlap seam. To separate the cuff-shaped outer part 3 from the inner container 2, a tear strip 45 is again provided here, which, however, extends in the circumferential direction around the perimeter of the outer part 3. In the region of the longitudinal side 37 of the overlapped end 34 in the lying portion of the wall of the outer part 3 a tear tab 39 is formed. This can be done using attenuation lines 51, as in FIG. 10, the description of which is given above. For the formation of the tear strip 45, it may be preferable if one, but preferably two material sections 40 extending in the circumferential direction, are provided in the overlap zone 35 between the two longitudinal sides 36, 37, in order to ensure that this reinforced zone also tears when the tear strip is torn.

Along the tear strip 45 can be provided on both sides of the weakening of the material, for example, in the form of perforations 38.

However, regardless of this, it is possible to form a tear tab 39 directly in the form of an integral part of the tear strip 45, and for easier capture of the tear tab 39, a notch 48 can again be provided, shown already in FIGS. 8 and 9.

In the embodiment shown here, the tear strip 45 is located approximately in the middle between both end zones 18, 28 when viewed in the direction of the longitudinal axis 4. However, independently of this, it is also possible to arrange the tear strip 45 in the circumferential direction toward the bottom 9 of the end zone 18. This the situation is shown by dashed lines in the lower end zone 18. Due to this, you can separate the end zone of the outer part 3, which usually rests on the not shown protrusion of the inner container 2 and, thus, prevents accidental The separate separation of the outer part 3 from the inner container 2.

Another possibility of arranging the tear-off strip 45 consists in its spiral execution around the circumference between the upper end zone 28 and the lower end zone 18.

12 and 13 show another possible and, if necessary, independent embodiment of the combined packaging container 1, and again the same parts are denoted by the same reference numbers as in the previous ones. 1–11. To eliminate unnecessary repetitions, reference is made to the detailed description in relation to the previous FIGS. 1–11.

Both of these shown on an enlarged scale fragment of the inner container 2 and the outer part 3 belong to that embodiment, which is already described with reference to figures 1 and 2. The plane of the cross section for the image in Fig.12 is selected so that it represents an axial section through a longitudinal axis 4, as well as zone 35 overlap. The tear tab 39 is again an integral part of the overlap zone 35 between both longitudinal sides 36, 37 of the ends 33, 34. In addition, the possibility of flanging or folding in the bottom zone is also shown. the lower end zone 18 of the outer part 3 and the location of the folded edge 29 in the above receiving space 13.

For easier actuation of the tear-off strip, in particular by means of its tear-off tongue 39, in the bottom zone 9 of the inner container 2, it can have a gripping chamber 17 in the region of its circumferential abutment edge 50, which extends here in the radial direction of the bottom 9.

Since the load transfer and support of the entire combined packaging container 1 occurs, starting from the flange 10, through the outer part 3 to the supporting surface 23 of the combined packaging container 1, at this short distance the supporting edge 52 usually passing around is discontinuous. Due to this, it is easier to grab the tear-off tab 39 and, thereby, to begin the process of tearing.

On Fig shows another possible and, if necessary, an independent embodiment of the combined packaging container 1, while again the same parts are indicated by the same positions, as in the previous fig. 1–13. To avoid unnecessary repetitions, reference is made to the detailed description in relation to the previous FIGS. 1–13.

The combined packaging container 1 in this embodiment is again formed using the inner container 2, as well as the cuff-shaped outer part 3. The spatial shape of the inner container 2, as well as the spatial shape of the outer part 3, can be freely selected. The cuff-shaped outer part 3 again extends from the flange 10 located in the open end 5 region to the bottom 9.

In contrast to the aforementioned embodiments, in this case, the bottom end zone 18 of the outer part 3 facing the bottom 9 is supported from below by a support protrusion and serves, thereby, to hold the outer part 3 with a geometric closure on the inner container 2. This is well known, for example, from EP 0 929 455 B1. In addition, the aforementioned retracted portion 15 with the edge 16 for stacking on the inner container 2 can again be located in the bottom zone.

In the left part of FIG. 14, the cuff-shaped outer part 3 is positioned so that the overlap zone 35 is arranged to extend in the zone of an axial or longitudinal section relative to the longitudinal axis 4. The overlap zone 35 is shown in the form of layers 33, 34 arranged on top of each other. outer part 3. The tear strip 45 also passes between the two end zones 18, 28 located at a distance from each other in the direction of the longitudinal axis 4 in the overlap zone 35.

Since they are trying to reduce the use of plastic material to form the inner container 2, the thickness of the film strip to be deformed is also constantly reduced. This film strip to be deformed forms a flange 10 in an almost undeformed form, due to which the thickness of the flange 10 in the direction of the longitudinal axis 4 is determined by the thickness of the selected film. The thinner the flange 10 is made, the more problematic is the opening of the combined packaging container 1 in the area of its open end 5.

Typically, the open end 5 is closed by a sealing process with a simplified depiction of the closing element 54. Due to the sealing process of the closing element 54 in its edge zone with the flange 10, a well-mating connection between the two structural elements is made here. For separating, respectively, pulling the closing element 54 from the flange 10, it preferably has a gripping tongue 55 that protrudes beyond the outer edge of the flange 10. Thereby, the tearing process, respectively, the opening process can be facilitated. The thinner the wall thickness of the flange 10, the greater the risk that during the opening process, the flange 10 will be separated, respectively, torn off, and this gap will continue into the side surface 8 of the container, due to which the product located in the filling space 7 may exit the combined packaging containers 1, respectively, to penetrate between the inner container 2 and the outer part 3.

To prevent this, with finely made flanges 10, a predetermined separation band 54 may be provided in the area of the closure member 54, which extends from the grip tab 55 across the closure 54 to the opposite flange 10. For easier opening of the closure 54 at least one, but preferably two, weakening zones 57 are formed, starting from the grip tab 55. When performing the weakening zone 57, it should be borne in mind that in any case, liquid-tight, and, if necessary, even gas-tight across the entire surface of the closure element 54 closure of the filling space 7 must be ensured. The predetermined separation strip 56 is continued using the additionally located on it, respectively formed by it of the connecting element 58 in the form of a strip-shaped structural element through the flange 10 to the tear strip 45 of the outer part 3. At this end the howling tongue 59 of the connecting element 58 is fixedly connected to the tear strip 45 made here in the overlap zone 35.

Due to this, it is possible to start the process of tearing off the closing element 54, starting from the grip tab 55, through the strip 56 of a given separation. Due to this, after the subsequent removal of the remaining parts of the closing element 54, it is possible to create access to the filling space 7. After the subsequent extraction of the filling product, the tearing process can be continued using the specified separation strip 56 and the connection element 58 formed by it further on to the tear strip 45. By connecting the connecting element 58 with the tear strip 45, the outer part 3 can also be further divided and removed from the inner container 2 after its section Nia.

In this case, it is possible to make the closing element 54 in the form of an independent structural element with the connecting element 58 integrated thereon and to connect this unit after filling the space 7, on the one hand, with the flange 10 and, on the other hand, the connecting element 58, in particular, end tongue 59 - with the outer part 3, in particular, with its tear strip 45.

However, regardless of this, it is also possible to make a blank for forming the outer part 3 so that it surrounds not only the side surface 8 of the container, but also as an integral component also the connecting element 58, as well as the closing element located on it, as shown in simplified view in Fig.16.

In this embodiment, as a whole, one should pay attention to the fact that for the subsequent tearing process, the strip 56 of a given separation of the closing element 54 immediately above the connecting element 58 passes into the overlap zone 35 and is located there at that end 33, 34, which lies closer to the inner containers 2 and is blocked by the other end 34, 33. Due to this embodiment, the connecting element 58 can then serves as a gripping tongue, which then continues in the tear strip 45 and, thereby, in turn facilitates the process of ess tearing off.
