Description

The invention relates to a cuff-shaped outer part for wrapping a cup-shaped inner container for forming a combination packaging container and a combination packaging container with a cuff-shaped outer part, as described in the claims 1, 2 and 12.

A 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.

WO 98/013 270 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. As axial fixation, the inner container in the region of its two mutually distanced ends on the one hand on a bead and on the other hand on a flange. Between these extends the cuff-shaped outer part and is additionally supported on it also from. Thus, it was not possible in all cases to transfer high stacking forces, since in the bottom region of the inner container by the support of the cuff-shaped outer part thereon damage to the bottom retaining edge is done.

From DE 19 509 100 A1, a two-part packaging container with a plastic cup and a cardboard sleeve has become known. The paperboard sleeve is formed from a carton blank having an overlap seam which tapers downwardly and fits snugly against the plastic cup. In the overlapping region, the outer and overlapping end in the region of the longitudinal extension between the two axially spaced-apart end regions own tear marks on. Thus, it is possible to detect the overlapping end in the region of the outer longitudinal edge and thus to release the outer, overlapping end of the underlying and overlapped end by severing the overlap seam, such as a bond or the like. The disadvantage here is that the separation of the seam was not feasible in all applications properly and it also came to an uncontrolled tearing of the cardboard sleeve depending on the adhesive force of the connecting seam.

From DE 20 2004 015 374 U1 a container for foods such as dairy products and the like has become known, which has a cup and a cuff. The cup in turn has a bottom surface and a skirt portion. The sleeve surrounds at least a portion of the skirt portion of the cup. In its open end, the cup has a stepped step, which serves as a stop for the cuff. Below this stage, a plurality of profiles are formed in the region of its jacket portion on the outside, which serve as retaining cams for the cuff. The skirt portion of the cup is conically tapered from the open end to the bottom formed, however, wherein the sleeve has a cylindrical shape and so the cuff blank in the developed state has a substantially rectangular shape. To compensate between the cylindrical sleeve and the conically tapering shell section, the sleeve is flanged in the region of the bottom and forms a larger bead.

DE 29 501 247 U1 describes a combination packaging of several materials, which are preferably selected from plastic and paper. The combination package comprises a stackable, plug-in box, which is in a wound cylinder, preferably made of paper. This cylinder is provided in the area of the bottom with a flange and is supported on the jacket of the inner box. In its open end, the plug-in box has a specially shaped upper edge, which serves for sealing with a sealing disc. Furthermore, the combination packaging is provided with a preferably resealable plastic lid. The curl is supported on the smooth outer wall of the inwardly offset shell portion of the plug-in box.

DE 3 326 369 C2 and EP 0 102 522 B1 describe a method for producing a conical plastic container with an opening edge projecting outwardly by deep drawing. The production of this combination packaging container takes place in that the sleeve is inserted into the thermoforming mold of a thermoforming device and then the conical container is deep-drawn into the sleeve, ie inline. The deep-drawn inner part connects in this way form-fitting with the outer part of the finished combined packaging container. The cuff also has a crimping inward, thereby concealing the lower cut edge of the cuff so that moisture can not penetrate it. Furthermore, the lower edge of the sleeve is underlined by a circumferential radially outwardly projecting edge of the bottom part. This results from the fact that the sleeve is arranged in a corresponding axial position in the deep-drawing mold. During thermoforming, the thermoforming sheet clings tightly against the inside of the sleeve by compressed air. The firm connection between the plastic layer and the sleeve can be additionally improved by molded into the container wall surveys. This survey may additionally serve as a stacking edge in a plurality of stacked and nested Kombi packaging containers.

The CH 693 611 A5 also describes a combined packaging container with a prefabricated from cardboard or a rigid paper shell part with a deep-drawn inner container 2. The prefabricated shell part is placed in the thermoforming mold, so that when deep drawing the inner container closely to the Cladding conforms. In the bottom area, the shell part has a folded over inward Umfalzung, which forms a bottom edge by a bead-shaped folded edge. A groove pressed into the cardboard material of the fold has two wall beads protruding toward the container interior. The inner container is deep-drawn so far into the casing part, that its thin wall on the one hand surrounds the cut edge of the Umfalzung and on the other hand extends over the profiled by the groove with the Wandwülsten area. Due to the close fitting during deep drawing results in a good positive connection with the shell part, which counteracts a withdrawal of the inner container from the shell part. The bottom wall of the inner container is disposed at a distance from the bottom edge of the container formed by the fold so that the part of the fold extending downwardly from the bottom wall forms an annular container foot.

The present invention has for its object to improve the separability of the outer part of the cup-shaped inner container and to provide a provided with such an outer part combined packaging container.

This object of the invention is solved by the features of claim 1. It is advantageous that the possibility created by the outgoing from the bottom area tear strip the cuff-shaped outer part by separating the Aufrissstreifens in its the end of the combined packaging container end facing so far can zoom in so far that a simple decrease is possible. Thus, it becomes possible for a user to depress the entire combination packaging container starting from its open end onto the footprint and then to begin the separation process by means of the tear-off tab and thereby sever the perforation in order subsequently to be able to detach the jacket-shaped outer part from the inner container. The tear-open flap makes it easier to operate the tear-off strip. The tear-off tab can be an integral part of the tear-off strip or can also be a separate component associated therewith.

The object of the invention is also achieved independently by the features of claim 2. The advantages resulting from the combination of features of this claim are that such a blank or a cuff-shaped or shell-shaped outer part raised therefrom can be created in which there is a stable overlapping area and nevertheless the possibility exists of the outer part, which is usually held in a form-fitting manner on the inner container for a separate disposal of this decrease. By distributed mostly over the circumference arranged and designed as a predetermined separation area tear strip the possibility is created to be able to enlarge the cuff-shaped outer part by separating the tear strip in its the end of the combined packaging container end facing so far circumferentially that a simple decrease is possible. The fact that the or the tear-off strips extend only over a partial height of the outer part, this remains after the Aufriss- and removal process as a closed jacket, which is only partially separated starting from the bottom area. The shorter the tear-off strips are torn, the longer the undamaged portion of the outer part remains.

A further advantageous embodiment of the Aufrissstreifens for the outer part is characterized in claim 3.

It is also possible embodiment according to claim 4, as this transverse forces are avoided and so during the Aufrissvorganges the outer part is pressed in the direction of the flange, which also higher forces can be expended for the demolition process.

Further advantageous embodiments are described in claims 5 and 6, since the operation of the Aufrissstreifens is facilitated. The tear-off tab can be an integral part of the tear-off strip or can also be a separate component associated therewith.

An advantageous development is described in claim 7, since it is possible for a user to depress the entire combination packaging container, starting from its open end on the footprint and then begin by means of the tear tab the separation process and thereby sever the perforation so as to be able to subsequently detach the jacket-shaped outer part from the inner container.

But it is also possible training according to claim 8, as such an exact initiation of the demolition movement is made possible.

A further advantageous embodiment of the outer part is characterized in claim 9.

A further advantageous embodiment is described in claim 10, as so selectively a separation starting from only one of the end portions or even a bilateral separation of the outer part is made possible by the inner container.

But is also an advantage according to claim 11, since in the region of the bottom an open cut edge is avoided.

The object of the invention is, however, independently solved by the features of claim 12. The advantages arising from the combination of features of this claim are that such a combination packaging container is created in which a detachment process of the outer part of the inner container is easily possible.

Furthermore, an embodiment according to the features specified in claim 13 is advantageous, as in spite of a detachable connection, a stable combination packaging container for receiving a variety of contents has been created.

An even better carrying capacity of the combination packaging container is achieved according to the embodiment as described in claim 14.

Finally, the gripping the Aufrisslasche is facilitated when a grip chamber is formed in the container shell of the inner container, as described in claim 15.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

Introductoryly it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or identical component names, wherein the disclosures contained in the entire description can be analogously applied to the same parts with the same reference numerals or identical component names. Also, the location information selected in the description, such as e.g. top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to a new position analogously to the new situation.

All information on ranges of values in the present description should be understood to include any and all portions thereof, e.g. is the statement 1 to 10 to be understood that all sub-areas, starting from the lower limit 1 and the upper limit 10 are included, ie. all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7 or 3.2 to 8.1 or 5.5 to 10.

In Figs. 1 to 3 a combination packaging container 1 is shown in simplified form, comprising in this embodiment, a cup-shaped inner container 2, in particular of a plastic material, and a surrounding the inner container 2 cuff-shaped outer part 3. The inner container 2 may be formed of any plastic materials or else other thermoformable biodegradable materials.

The inner container 2 comprises in the direction of its longitudinal axis 4 distanced from each other an open end 5 and a closed end 6. A filling space 7 of the inner container 2 is bounded by a container shell 8 and a bottom 9 and can accommodate different foods, dairy etc. serve. Furthermore, the inner container 2 may have, in the region of its open end 5, a flange 10 which projects beyond the container jacket 8 to the outside. This flange 10 is preferably arranged continuously over the outer circumference of the inner container 2 and is usually also used as a sealing flange for sealing and the associated completion of the filling chamber 7 relative to the external ambient conditions after the filling of the same.

The cuff-shaped outer part 3 surrounds in its wound or erected state the inner container 2 in the region of its container shell 8 and covers this circumference preferably completely.

The combi-packaging container 1 shown here is made so that the inner container 2 is made separately from the cuff-shaped outer part 3 and the two components are stored or processed separately from each other until the final assembly or the joining process. This makes it possible to produce uniform inner container 2 for a variety of Befüllgüter and shortly before the filling or even after filling the cuff-shaped outer part 3 together with the inner container. If the outer part 3 erected or wound into a jacket and assembled as a component, this can be pushed onto the inner container 2 and the inner container 2 are inserted into the cuff-shaped outer part 3. Regardless, it would still be possible to wrap the blank to form the outer part 3 directly to the spanned on a mandrel inner container 2 and then connect to the outer part 3. By this process, only the combination packaging container 1 is formed. In the case of very small wall thicknesses of the inner container 2, these can indeed be produced separately from the outer parts 3, but should already be assembled prior to filling into the Kombi packaging container 1.

Regardless, it would also be possible to first form the jacket-shaped outer part 3 of the blank and then insert this before molding the inner container 2 in a deep drawing mold, not shown here, and then to start only with the transformation of a thermoformable film. This process is referred to as so-called inline production. This gives you equal to a complete combination packaging container 1, which can then be filled later without additional installation effort for the assembly of inner container 2 and 3 outer part is obtained.

Furthermore, it is shown here that in an immediate transition region 11, starting from the bottom 9 towards the container casing 8 in the container casing 8 with respect to the container casing 8 inwardly offset wall portion 12 is formed to form a circumferential receiving space 13. Subsequent to the inwardly offset wall section 12, a step 14, which is seen in longitudinal section or axial section of the inner container 2 with respect to the longitudinal axis 4, is formed toward the container casing 8, which leads over or leads over. This shoulder 14 is usually arranged in a direction perpendicular to the longitudinal axis 4 aligned plane and forms a directed outward with respect to the filling chamber 7 stage.

In the here cup-shaped inner container 2, the container shell 8 and / or the inwardly offset wall portion 12 with respect to the longitudinal axis 4 of the inner container 2 are each tapered, starting from the open end 5 toward the bottom 9. In this case, the conicity of the container casing 8 may preferably be selected differently from the conicity of the inwardly offset wall portion 12. Preferably, the conicity of the container casing 8 with respect to the conicity of the inwardly offset wall portion 12 is chosen to be smaller. This means that the inwardly offset wall portion 12 seen in longitudinal section with respect to the longitudinal axis 4 tapers more towards the bottom 9.

Following on to the container shell 8 merging or projecting outwardly paragraph 14, the inner container 2 then seen at this in longitudinal section, at the side facing away from the inwardly offset wall portion 12 a respect to the container shell 8 to konterkonischen rear train 15 for training a stack edge 16. Furthermore, in the region of the inwardly offset wall portion 12 of the inner container 2, a handle chamber 17, shown schematically in the lower left area of FIG. 1, can be arranged or formed. The use and significance of this grip chamber 17 will be described in more detail below.

As can now better be seen from a synopsis of FIGS. 1 and 2, the sleeve-shaped outer part 3 in the region of the bottom 9 of the inner container 2 facing bottom end portion 18 has a preferably crimped inward fold edge 19. This folded folded edge 19 can be produced by turning over a portion of the cuff-shaped outer part 3, it being advantageous if the folded edge 19 is circumferentially continuously applied to the cuff-shaped outer part 3 during flanging. To achieve an additional stability of the outer part 3, it may prove advantageous if the seaming edge 19 at least partially connected to the wall of the cuff-shaped outer part 3, in particular glued, is.

Regardless of this, it would also be possible to form the fold edge 19 by its own component independent of the blank and to connect it to the outer part 3 for reinforcement. Thereby, e.g. larger differences in wall thickness between the outer part 3 and fold edge 19 can be achieved.

As described above, the inwardly offset wall portion 12 forms the receiving space 13, in which the seaming edge 19 is received during telescoping and the associated formation of the combination packaging container 1. With respect to the longitudinal axis 4, the cuff-shaped outer part 3 has a height 20 which corresponds to at least a distance 21 between the flange 10, in particular its bottom 9 facing the bottom, and a bottom 22 of the bottom 9.

This makes it possible, supporting or stacking forces, which are introduced to the combination packaging container 1 in the direction of the longitudinal axis 4 on this in the region of the flange 10, directly from the flange 10 via the cuff-shaped outer part 3 on a footprint shown in simplified form 23 of the combination packaging container 1 can be transmitted. This can be found with minimum wall thicknesses to form the container shell 8 or 9 of the bottom of Auslangen. The transmission of the supporting forces takes place exclusively starting from the flange 10 via the cuff-shaped outer part 3 and the end portion 18 toward the footprint 23. To achieve sufficient tightness of the container casing 8 and the bottom 9 must have a sufficient wall thickness to meet these requirements , But it is also on the diffusion properties or the passage of gases or water vapor through the material of the inner container 2 to take care.

As already described above, the inwardly offset wall portion 12 is provided to form the receiving space 13. The wall section 12 of the container casing 8 is seen in longitudinal section of the inner container 2, each side offset at least by a dimension 24 inwardly in the direction of the longitudinal axis 4, wherein the extent 24 corresponds to at least one thickness 25 of the folded edge 19. In accordance with tight tolerances selected here not only a certain clamping effect between the cuff-shaped outer part 3 and the inner container 2 can be achieved, but also a corresponding gain of the transition region 11 from the bottom 9 to the container shell 8 can be achieved.

Furthermore, it is also possible that a circumferential and the open end of the inner container 2 facing end edge 26 of the seaming edge 19 seen in the longitudinal section of the inner container 2 comes to rest on the inwardly offset wall portion 12 towards the container shell 8 passing paragraph 14 to the plant , This results in an additional support and stiffening of the container casing 8 in this wall section 12. Thus, the pressure force of the bottom-side mass of the filling material is introduced via the container casing 8 directly into the cuff-shaped outer part 3.

Furthermore, it may prove to be advantageous, as best seen in FIG. 2, when formed on the cuff-shaped outer part 3 in the portion of the counter-conical trail 15 at least one protruding into the Konterkonischen pull 15 bead 27 or disposed thereon , By this bead 27, it is possible to achieve a mechanical connection for holding the cuff-shaped outer part 3 on the inner container 2.

In Fig. 2 is further simplified schematically illustrated with dashed lines that the overall height 20 of the cuff-shaped outer part 3 with respect to the inner container 2 is chosen so large that the bottom 9 of the inner container 2 of this facing the bottom end portion 18 of the cuff-shaped Outer part 3 is surmounted. Thus, the height 20 of the cuff-shaped outer part 3 has been chosen larger than the distance 21 between the lower edge of the flange 10 and the bottom 22 of the bottom 9, as has already been described in detail in FIG.

By this projection of the cuff-shaped outer part 3, in particular by the bottom-side seaming edge 19, a distancing of the bottom 9 is achieved by the footprint 23 and so scored a circumferential support of the combination packaging container 1 at the folded outer part 3. By supporting the folded portion of the fold edge 19 on the contact surface 23, it is possible to apply the printing of the cuff-shaped outer part 3 over the entire surface up to the contact surface 23 or the bottom 9, thereby still a higher strength and rigidity of the entire combination. Packaging container 1 can be achieved.

If the supernatant of the cuff-shaped outer part 3, indicated in dashed lines, is further increased beyond the bottom 9 in the region of its seam edge 19, the arrangement or design of the stack edge 16 may be dispensed with. The support for nesting of combination packaging containers 1 can then take place from a protruding fold edge 19 of the first sleeve-shaped outer part 3 on the offset from the inwardly facing wall portion 12 outwardly leaping paragraph 14 of the other inner container 2.

In Fig. 3 is an additional possible embodiment of the cuff-shaped outer part 3 in its upper and the flange 10 facing end portion 28 is shown simplified. The cuff-shaped outer part 3 here has a further additional fold edge 29, which may be formed analogously to the previously described fold edge 19. The folded edge 29 is also preferably turned inside out, whereby no additional disturbing edges are arranged on the outer side of the sleeve-shaped outer part 3 facing the viewer. It is still possible, not the folded edge 29 over the entire circumference of the outer part 3, but only partially form. To accommodate the folded edge 29, the container shell 8 has a further inwardly offset wall portion 30, which forms a further receiving space 31 for the seam edge 29. But it would also be possible to turn over only the other fold edge 29 and to dispense with the arrangement of the inwardly offset wall portion 30 and the thereby formed receiving space 31. For demolding of the inner container 2, the inwardly offset wall portion 30 located in the region of the flange 10 may possibly cause problems since an inwardly projecting edge is thus formed in the outer shape of the tool. However, the conicity of the container shell 8 can be counteracted.

When assembling the cuff-shaped outer part 3 with the inner container 2, the further folded edge 29 is pushed together with the outer part 3 so far in the direction of the flange 10 until that the folded edge 29 in the space provided for receiving 31 in the region of the open end 5 of the inner container 2 snaps. As a result, a mechanical locking of the cuff-shaped outer part 3 on the inner container 2 can be achieved. This further seaming edge 29 is preferably applied to the casing or the wall of the cuff-shaped outer part 3 during beading in a circumferentially continuous manner, as has already been described above for the first seaming edge 19. Regardless, it would also be possible, instead of the inwardly offset wall portion 30 to provide outwardly projecting locking projections, which serve to fix the other fold edge 29 on the container shell 8.

Furthermore, it would also be possible to divide the upper fold edge 29 seen over the circumference into a plurality of fold edge sections 29 or to form only individual such fold edge sections 29. If a plurality of folded edge portions 29 are provided, these can alternately be folded or flanged viewed in the circumferential direction and / or be deformed outwardly under the flange 10, as shown in simplified lines in dashed lines. If only individual folded edge sections 29 are formed or provided outwards, then the arrangement of the inwardly deformed wall section 30 can be omitted altogether. It is advantageous or is always ensured that the flange 10 facing end portion 28 of the jacket-shaped outer part 3 comes to rest on the flange 10 and so an uninterrupted introduction of force is ensured in the outer part 3.

To achieve sufficient support and power transmission, it is further advantageous if the cuff-shaped outer part 3 is formed with its inner surface 32 close fitting to the outer surface of the container shell 8 of the inner container 2. As a result, not only is there sufficient static friction between these two components, but also an all-round optimum force transmission takes place starting from the filling material to the cuff-shaped outer part 3.

An even better load-bearing capacity of the combination packaging container 1 is achieved when the sleeve-shaped outer part 3 is connected via a peelable, preferably full-surface, bonding with the container jacket 8 of the inner container 2. Under a peelable connection or bonding is understood a connecting means between the mutually facing surfaces, which ensures sufficient adhesion, but is easily removable for the separation process of the outer part 3 from the inner container 2, without causing destruction of the components. As a result, not only is sufficient adhesion ensured throughout the entire use of the combination packaging container 1, but additionally also a perfect separation of the sleeve-shaped outer part 3 from the inner container 2 is made possible, as will be described in more detail below.

In FIG. 4, the cuff-shaped outer part 3 is shown prior to telescoping with the cup-shaped inner container 2 and the inner container 2 to be formed therein. This has already been wound starting from a planar blank to a mantle. By winding the planar blank then facing ends 33, 34 are interconnected in a simplified overlap region 35 shown. This is done by a so-called overlap seam. The winding as well as the connection of the two ends 33, 34 can thereby, as already well known from the prior art, e.g. done by gluing. Reference is made here to EP 0 408 515 B1 or reference and the disclosure is incorporated into the present application.

Furthermore, it is also simplified here shown that at least one longitudinal side 36, 37 of the overlap region 35 in the cuff-shaped outer part 3, a material weakening, such as a notch, bead or a perforation 38 shown here, arranged or formed therein. The weakening of the material, such as the perforation 38, is shown simplified by short angled lines and can also be arranged or formed directly in or within the overlapping region 35. The above-described perforation 38 is used to sever the wound shell of the cuff-shaped outer part 3. In order to carry out this opening movement easier, a tear-off tab 39 can be arranged or provided in the overlapping region 35. In this embodiment shown here, the tear-off tab 39 is facing the bottom 9 of the inner container 2. This makes it possible for a user to depress the entire combination packaging container 1, starting from its open end 5 on the footprint 23 and then by means of the tear tab 39 to begin the separation process and thereby to sever the perforation 38, so subsequently the jacket-shaped outer part to be able to detach from the inner container 2.

In order to facilitate the gripping of the tear-open tab 39, the handle chamber 17 shown and described in simplified form in FIG. 1 can serve, in which case only a corresponding mutual orientation or overlapping position during joining or telescoping of the inner container 2 and cuff-shaped outer part 3 is necessary.

However, it would still be possible in the subsequently interlocked components to form the grip chamber 17 with respect to the circumferential extent of the tear-off tab 39 to larger peripheral area, so as to provide a certain tolerance in the mutual alignment prior to assembly.

If the handle chamber 17, however, formed as a recess passing over the circumference, a mutual orientation when telescoping the two components is no longer necessary.

To form the tear-open tab 39 in the overlapping region 35, it is advantageous if at least in the region of one of the longitudinal sides 36, 37 of the overlapping region 35 a material weakening and / or a material severing 40 is attached or provided. Material weakening is understood to mean a stamping line, a notch, a bead and, as a material cut-through 40, a cut, a punching or the like. The material separation 40 preferably extends in the direction of the longitudinal side 36, 37 and can also pass through the inner and crimped seam edge 19 of the outer part 3 or else there the material weakening be arranged. Preferably, however, the material separation 40 is assigned to the two longitudinal sides 36, 37. This allows both long sides 36, 37 serve as Aufrissbereich.

The tear-open tab 39 can be formed either only from the portion of the overlap region 35 closer to the inner container 2 or only from the portion of the overlap region 35 which is distant from the inner container 2. However, it would also be possible for the tear-open tab 39 to comprise both sections of the overlapping region 35 arranged one above the other and thus to have twice the wall thickness. By crimping the seaming edge 19, the total thickness of the tear-off tab 39 is additionally increased. In order to avoid or reduce this, it would be possible to remove parts of the overlapping region 35 in the region of the tear-open tab 29. This can already be done when flat blank or only in the course of the production of the outer part 3 are performed. Thus, the tear-open tab 39 is part of the overlapping region 35 or of a predetermined separation line or tear-off strip 45 formed thereby, which extends here over the entire height of the outer part 3 in the direction of the longitudinal axis 4.

Since in this embodiment shown here, the tear-tab 39 is associated with the bottom 9 of the inner container 2, the material cut-throughs 40 are also facing this.

In order to achieve an unintentional detachment and optionally a support of the cuff-shaped outer part 3 on the inner container 2, the separated by the material cut 40 in the overlapping region 35 section, such as the Aufrisslasche 39, via a connecting means, such as an adhesive, with the inner container 2 connected. This can be done, for example, by a glue point 41 shown in a simplified manner, on the one hand fixed the tear-open tab 39 fixed with respect to the inner container 2 and subsequently also holds the entire outer part 3 in its position on the inner container 2. Another adhesive point 41 is also indicated in the upper end region 28 of the outer part 3 here. It should be pointed out that the arrangement of at least one connecting region, such as the adhesive point 41, can take place in the entire section of the overlapping region 35 and can be chosen as desired.

FIG. 5 shows a further possible embodiment of the cuff-shaped outer part 3, which is possibly independent of itself, wherein the same reference numerals or component designations are used again for the same parts as in the preceding FIGS. 1 to 4. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs.

In this embodiment shown here, the cuff-shaped outer part 3 is again formed from a blank, which is connected to each other in the region of its facing ends 33, 34 in the overlapping region 35. Furthermore, the blank is folded along two fold lines 42, 43 and stored so planar until the assembly takes place with the inner container 2 or the outer part 3 is erected and placed in a thermoforming mold for inline production. The Aufrisslasche 39 may in turn be facing the bottom 9 of the inner container 2.

Regardless, it would also be possible to arrange the tear-off tab 39 with the material cut-throughs 40 in the region of the flange 10 of the inner container 2 on the sleeve-shaped outer part 3. In addition, however, the tear-off tab 39 could also be arranged or provided both in the region of the base 9 and in the region of the flange 10, so as to selectively detach, starting from only one of the end regions 18, 28, or else a separation on both sides to allow the outer part 3 from the inner container 2.

FIG. 6 shows a further optionally independent embodiment of the cuff-shaped outer part 3 or its blank, with the same reference numerals and component designations being used again for the same parts as in the preceding FIGS. 1 to 5. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs.

In the case of the planar and superimposed blank for forming the sleeve-shaped outer part 3, in contrast to the exemplary embodiment shown in FIG. 5, the overlapping region 35 is arranged in an edge region thereof. In the present embodiment, the fold line 42 also forms a boundary line 44 of the overlap region 35. Furthermore, the overlap region 35 on the other longitudinal side 37 is delimited by the perforation 38 described above. This in turn for the storage up to the assembly with the inner container 2 or the insertion into the thermoforming mold a flat-lying outer part 3 is created, which only has to be unfolded and pushed over for the connection process. Due to the planar blank for the jacket-shaped outer part 3, its printing and the optical design are significantly simplified.

Furthermore, it has proven to be advantageous if the cuff-shaped outer part 3 is formed with a net weight, which is relative to the total mass of the combination packaging container 1 in a lower limit of at least 50%. Characterized in that the cuff-shaped outer part 3 is made of a paper or cardboard material with different basis weights, so the proportion of the material of the inner container 2 can be constantly reduced. This is particularly true when the cuff-shaped outer part 3, viewed continuously and in cross section, extends in particular in a straight line between the flange 10 and the contact surface 23 of the combination packaging container 1, since a high intrinsic stability of the combined packaging container 1 is achieved. This high transfer forces can be transferred.

FIG. 7 shows a further optionally independent embodiment of the cuff-shaped outer part 3 in its erected position, again using the same reference numerals or component designations as in the preceding FIGS. 1 to 6 for the same parts. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS.

In this embodiment shown here, the erected blank for forming the jacket-shaped outer part 3 is shown with its overlap region 35. The two mutually facing ends 33, 34 with their longitudinal sides 36, 37 form here only the connection region of the blank to form the coat or cuff-shaped outer part 3. A corresponding bonding is provided here. In general, a tubular component is understood as the outer part 3, the spatial form of which is understood to be cylindrical up to conical or conical. The erected and assembled blank then forms the outer part 3, which, viewed circumferentially, forms a jacket between the end regions 18, 28 distanced from one another in the direction of the longitudinal axis 4. At least one predetermined separation area is intended to be provided or formed in this jacket or jacket area, with different configurations of the same being described in the following figures.

In order nevertheless to allow a separation of the outer part 3 after use of the inner container 2, starting here from the bottom arranged end portion 18 extending to the upper end portion 28 extending at least one, but preferably a plurality of circumferentially spaced Aufrissstreifen 45 is provided. The one or more tear strips 45 extend only over a partial height 46 of the outer part 3 between its two end regions 18, 28 in a preferred parallel orientation with respect to the longitudinal axis 4. characterized in that the or the tear-off strips 45 are assigned to the bottom 9 of the inner container 2 or starting extend from this, the circumferential dimension in the lower end portion 18 can be increased so that a simple decrease of the outer part 3 can be made from the inner container 2. In the case of a plurality of tear strips 45 distributed over the circumference, an even greater instability can be achieved after the partial separation of the outer part 3 so as to be able to remove the outer part 3, which is usually held in a form-fitting manner on the inner container 2. This is the case when the here the bottom 9 facing end portion 18 of the outer part 3 is grasped by a radially outwardly projecting shoulder and so in cooperation with the conical design of both the inner container 2 and the outer part 3, a mutual positional fixation of the two Components takes place. In order to facilitate the separation of the tear-off strip 45, this can in turn be associated with a tear-off tab 39 or a part of the tear-off strip 45 formed by the tear-off tab 39. To form the tear strip 45, a material weakening already described above, in particular an angularly aligned perforation 38, can in turn be arranged in the material or in the material for forming the outer part 3 so as to facilitate the separation of the outer part 3 along predetermined separation lines. Thus, the material weakenings limit the tear strip 45 laterally in its width with respect to its longitudinal extent.

In order to form the tear-open tab 39, it can prove advantageous if, starting from the lower end region 18 in this case, the material sever 40 is formed over a partial section of the partial height 46 in order to facilitate the actuation or operation of the tear-open tab 39. The material severing 40 thus interrupts the cohesion with the rest of the jacket of the outer part 3. As a result, these can be easily folded radially outward radially and then subsequently cut out along the material weakening or the perforation 38 as a result of the tear-off strips 45.

Since the blank of the outer part 3 always remains glued together in its overlapping region 35 and the tear strip or strips 45 extend only over the partial height 46 of the total height of the outer part 3 in the direction of its longitudinal axis 4, the outer part 3 remains in its basic form, wherein only by the partial separation of the bottom 9 facing peripheral region, the stability is reduced so that an unimpeded decrease from the inner container 2 can be done without problems. In addition, the previously described fold edge 19 could again be provided on the inside of the outer part 3, which may possibly avoid an open cut edge of the outer part 3.

In FIGS. 8 and 9, a further and optionally independent embodiment of the cuff-shaped outer part 3 is shown in its circumferentially assembled and folded position, again using the same reference numerals or component designations for the same parts as in the preceding FIGS. 1 to 7 become. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 7 or reference.

The blank is connected to its ends 33, 34 to form the overlapping region 35 to a circumferential component - ie the cuff-shaped outer part 3 -. The remote from the inner container 2 and the inner end 33 overlapping outer end 34 forms with its longitudinal side 37 in the direction of the longitudinal axis 4, a separation region 47. In this separation region 47, in turn, one or more material weakenings, in particular the perforation 38 may be provided. In the middle of the overall height of the outer part 3 in the direction of its longitudinal axis 4, at least one opening 48 is arranged in the wall section of the outer part 3 adjoining the overlapping area 35, which extends over an entire wall thickness 49 of the blank or of the outer part 3.

9 is schematically indicated that with a finger 50, in particular the thumb, by eliminating the material of the outer part 3 in the region of the opening 48, the longitudinal side 37 of the outer end 34 can be taken and thereby starting from Breakthrough 48 there on both sides of the separation region 47 forming perforation 38 can be separated by pulling away.

The detection of the longitudinal side 37 can additionally be improved if the aperture 48 extends circumferentially into the overlap region 35, thereby facilitating the gripping of this wall part. Thus, in turn can be spoken by a tear tab 39. Thus, the opening 48, optionally in combination with the tear tab 39, an actuating means.

FIG. 10 shows a further embodiment of the cuff-shaped outer part 3, which may be independent of itself, in its position folded together in the overlapping area 35 and folded flat, again with the same reference numerals or component designations for the same parts as in the preceding FIGS to 9 are used. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS.

Since this embodiment is very similar to the embodiment described in FIGS. 8 and 9, only the differences will be discussed. In place of the breakthrough 48 described above, the tear-off tab 39 is here designed in the manner of a window of an Advent calendar in the outer part 3, in which the tear-off tab 39 can be folded out along a U-shaped weakening line 51. On both sides of the tear-open tab 39 towards the two end regions 18, 28, the separating region 47 is again formed along the longitudinal side 37 of the end 34. This separation region 47 may again have a number of material weakenings, such as the perforation 38.

If now the entire outer part 3 are separated from the inner container 2, first the tear-off tab 39 is to be separated along the weakening line 51. Since the weakening line 51 terminates in the region of the longitudinal side 37 of the end 34, the opening force is transmitted on actuation of the tear-open tab 39 in the separating regions 47 arranged on both sides and the outer part 3 is separated along the perforation 38. The two mutually facing ends 33, 34 of the outer part 3 are in turn firmly connected to each other.

In the embodiments shown in FIGS. 8, 9 and 10, no separate tear strip 45 is formed, but the jacket-shaped outer part 3 is separated along the separation area 47. This separation area 47 is preferably aligned parallel to the longitudinal axis 4 and extends in a straight line between the two end regions 18, 28. The actuating means, such as the opening 48 and / or the tear-open tab 39, is arranged approximately centrally between the two end regions 18, 28 distanced from one another in the direction of the longitudinal axis 4.

FIG. 11 shows a further embodiment of the cuff-shaped outer part 3 as an assembled blank in a flat lying position, where appropriate, wherein the same reference numerals or component designations are again used for the same parts as in the preceding FIGS. 1 to 10 , To avoid unnecessary repetition, reference is made to the detailed descriptions in the preceding Figs.

Also in this outer part 3 shown here, the mutually facing ends 33, 34 are connected in the overlapping region 35 with each other in the form of an overlap seam. For separating the jacket-shaped outer part 3 from the inner container 2, the tear-off strip 45 is again provided here, which, however, extends circumferentially over the circumference of the outer part 3. In the area of the longitudinal side 37 of the overlapping end 34, the tear-off tab 39 is formed in the wall section of the outer part 3 lying underneath. This may be done similarly as previously described in FIG. 10 with the weakening line 51. To form the tear strip 45, it may prove advantageous if in the overlap region 35 between the two longitudinal sides 36, 37 one, but preferably two, circumferentially extending material separation 40 are provided so as to tear when tearing the Aufrissstreifens 45 also this reinforced area to be able to. Along the tear strip 45, material weakenings, for example in the form of perforations 38, can again be provided on both sides thereof.

Regardless, it would also be possible to form the Aufrisslasche 39 directly as part of the Aufrissstreifens 45 in the overlapping region 35, in which case the Aufrisslasche 39 again for ease of detection previously described in FIGS. 8 and 9 can be 48 provided.

In this embodiment shown here, the tear strip 45 is arranged approximately in the middle between the two end regions 18, 28 in the direction of the longitudinal axis 4. Regardless, however, an arrangement of the tear strip 45 would be circumferentially conceivable in the bottom 9 facing end portion 18. This situation is indicated in the lower end portion 18 in dotted lines. As a result, that end region of the outer part 3 can be separated, which is usually supported on a not-shown shoulder of the inner container 2 and thus prevents the outer part 3 against unintentional release of the inner container 2.

A further possibility of arranging the tear strip 45 would be to form it helically over the circumference between the upper end region 28 and the lower end region 18.

FIGS. 12 and 13 show a further embodiment of the combined packaging container 1, which may be independent of itself, wherein the same reference numerals or component designations are again used for the same parts as in the preceding FIGS. 1 to 11. To avoid unnecessary repetition, reference is made to the detailed descriptions in the preceding Figs. 1 to 11 or referenced.

These two enlarged details of inner container 2 and outer part 3 relate to that embodiment, as has already been described in FIGS. 1 and 2. The sectional plane for the illustration of FIG. 12 has been selected such that it represents an axial section through the longitudinal axis 4 and the overlap region 35. The Aufrisslasche 39 is in turn part of the overlap region 35 between the two longitudinal sides 36, 37 of the ends 33, 34. In addition, also the possibility is shown that in the region of the bottom, so the lower end portion 18 of the outer part 3 is folded or folded and the fold edge 29 is received by the previously described receiving space 13.

For ease of operation of the tear strip 45, in particular with its tear-off tab 39, in the region of the bottom 9 of the inner container 2, this in the region of its peripheral support edge 50, the grip chamber 17 which extends here in the radial direction of the bottom 9. Since the load transfer and support of the entire combination packaging container 1 takes place starting from the flange 10 on the outer part 3 toward the contact surface 23 of the combination packaging container 1, the normally completely continuous support edge 52 is formed interrupted over this short distance. This makes it possible to more easily detect the tear tab 39 and thus begin the Aufrissvorgang.

FIGS. 14 to 16 show a further embodiment of the combination packaging container 1, which may be independent of itself, wherein the same reference numerals or component designations are used again for the same parts as in the preceding FIGS. 1 to 13. To avoid unnecessary repetition, reference is made to the detailed descriptions in the preceding Figs. 1 to 13 or reference.

The combination packaging container 1 is again formed in this embodiment by the inner container 2 and the coat or cuff-shaped outer part 3. The spatial form of the inner container 2 and the outer part 3 can be chosen freely. The jacket-shaped outer part 3 in turn extends from the arranged in the region of the open end 5 flange 10 to the bottom of the 9th

In contrast to the embodiments described above, the here the bottom 9 facing lower end portion 18 of the outer part 3 is supported by a support shoulder 53 and thus serves for the positive retention of the outer part 3 on the inner container 2. This is well known, in which example EP 0 929 455 B1 is referred to. Furthermore, in turn, the above-described rear pull 15 with the stacking edge 16 on the inner container 2 can be arranged or formed in the bottom area.

In the left part of FIG. 14, the jacket-shaped outer part 3 is arranged such that the overlapping region 35 is arranged to extend in the region of the axial or longitudinal section with respect to the longitudinal axis 4. The overlapping region 35 was represented by the superimposed layers of the ends 33, 34 of the outer part 3. The tear strip 45 likewise extends between the two end regions 18, 28 which are distanced from one another in the direction of the longitudinal axis 4 in the overlapping region 35.

Since it is attempted to reduce the use of material to plastic to form the inner container 2, and the thickness of the film strip to be deformed is steadily reduced. This film strip to be deformed forms the flange 10 in almost undeformed form, which results in the thickness or thickness of the flange 10 in the direction of the longitudinal axis 4 by the selected film thickness. The thinner the flange 10 is formed, the more problematic is the opening of the combination packaging container 1 in the region of its open end 5.

Usually, the open end 5 is closed by a sealing process with a closure element 54 shown in simplified form. By the sealing process of the closure element 10 in its edge region with the flange 10 takes place here a well-adhering connection between these two components. To remove or remove the closure element 54 from the flange 10, this advantageously has a grip tab 55, which projects beyond the outer edge of the flange 10. Thus, the demolition process or opening operation can be facilitated in a known manner. The thinner the wall thickness of the flange 10 is, the more there is a risk that during the opening process, the flange 10 is in any case separated or torn and this crack continues into the container shell 8, whereby the contents received in the filling chamber 7 from the combination Packaging container 1 escape or between the inner container 2 and the outer part 3 can penetrate.

In order to avoid this with thin flanges 10, a predetermined separation strip 56 can also be provided in the area of the closure element 54, which extends starting from the grip flap 55 across the closure element 54 as far as the opposite flange 10. For easier opening of the closure element 54, at least one, but preferably two weakened regions 57 can be formed, starting from the gripping tab 55. When forming the weakened region 57, care must be taken that in all cases a liquid-tight or possibly even gas-tight closure is ensured over the entire surface of the closure element 54 towards the filling space 7. The set separation strip 56 continues by means of a connecting element 58 additionally arranged thereon or formed by it as a strip-shaped component over the flange 10 to the tear strip 45 of the outer part 3. An end tab 59 of the connecting element 58 is fixedly connected to the here in the overlap region 35 formed tear strip 45.

This makes it possible to start the Aufrissvorgang of the closure element 54, starting from the grip tab 55 on the predetermined separation strip 56 away. As a result, access to the filling space 7 can be created after the removal of the remaining elements of the closure element 54. After appropriate removal of the filling of the Aufrissvorgang can be continued by means of the predetermined separating strip 56 and arranged thereon or thereby formed connecting element 58 up to the tear strip 45. By the connection of the connecting element 58 with the tear strip 45 and the outer part 3 can be further separated and in turn be removed from the inner container 2 after separation thereof.

It is possible to form the closure element 54 as an independent component with the integrally attached thereto connecting element 58 and this assembly after filling the filling chamber 7 on the one hand with the flange 10 and on the other hand, the connecting element 58, in particular its end tabs 59, with the outer part 3, in particular its tear strip 45 to connect.

Regardless, it would also be possible to form the blank to form the outer part 3 such that this not only envelops the container shell 8, but also the connecting element 58 and the closure element arranged thereon is arranged as an integral part of it, as the 16 is shown simplified in FIG.

In such a one-piece design is to ensure that for the subsequent Aufrissvorgang the predetermined separation strip 56 of the closure member 54 passes directly through the connecting element 58 in the overlap region 35 and there is arranged at that end 33, 34 which closer to the inner container 2 is located and overlapped by the other end 34, 33. With this training, the connecting element 58 can then serve as a handle flap, which continues in the tear strip 45 subsequently and thus in turn facilitates the Aufrissvorgang.

For the sake of order, it should finally be pointed out that, for better understanding of the design of the combination packaging container 1, this or its components have been shown partly in an unmeshold manner and / or enlarged and / or reduced in size.
