Description

The invention relates to a container combination of at least two container parts, which are formed by a cup-shaped base container and an additional container, arranged one above the other and detachably connected to each other, wherein the basic container and the additional container in each case at least one container shell, a container bottom and in the direction of a longitudinal axis distanced from each other Having ends, and the additional container with its end facing the base container in an overlap region, the end overlaps with the container bottom of the base container in the direction of its container shell and at least the overlapping region is wrapped by a shell-like enveloping element, which is formed as over the circumference continuously formed outer part.

From the DE 199 24 871 A1 a container combination of containers with two closed or closable receiving spaces has become known, which is formed by two co-directionally arranged one above the other and detachably interconnected container parts for each receiving space. The upper container part is cup-shaped and closes with its bottom a flat lower container part. For the detachable connection of the two container parts locking means are formed on both container parts. The two container parts are enclosed in the Beriech their container shell by a removable shrink film, which also extends radially inwardly over the bottom edge of the lower container part. Due to the applied shrink film could be achieved in many cases, a useful tamper evidence. However, it could not be achieved in all cases a perfect presentation of the enclosed in the lower space article.

The EP 0 896 930 A1 describes cup-shaped container for food, which are arranged one above the other and detachably connected to each other. Between the two container parts of the container combination, an overlap region is provided. In this case, the lower container part overlaps with its open end the bottom portion of the upper container part in the region of its container shell, wherein the upper container part in this section has an inwardly projecting offset so as to achieve a planar transition of the wall parts of the two containers in the outer edge region. The two container parts are also conically tapered educated. For mutual positional fixation of the two nested container parts they are wrapped by a shell-like envelope element, which is formed continuously over the circumference. This band-like wrapping element is designed as an adhesive tape or tape, so as to connect the two container parts to intentional separation from each other.

From the DE 82 26 733 U1 is a cup combination for packaging food has become known in which a lid of the cup combination itself is designed as a cup and forms with its bottom the closure of the lower cup. For mutual connection or coupling of the two container parts of the upper and the lower cup over a small part of the height of the lower cup is inserted into each other and held fixed in the nested position relative to each other. For this purpose, the upper container part on a counter-rotating to the container shell in the direction of the receiving space inwardly projecting wall portion over which a trained opposite to this upper edge strip of the lower container part is snapped for mutual support. A flange projecting outwards at the upper end region of the lower cup is supported on an annular surface of the upper cup which merges with the container jacket. Another additional support of the bottom of the upper cup takes place on a parallel to this aligned annular surface of the lower cup.

The FR 2 701 924 A1 describes a container made of metal, which is closed at both end regions with a closure lid. At half the height, a circumferential constriction is arranged in the container casing, which engages in a peripheral recess of an intermediate bottom formed opposite thereto. Thus, the interior of the container can be divided into two separate subspaces.

Other vessels with at least two chambers are for example from the DE 94 05 246 U1 , of the DE 94 14 038 U1 , of the DE 76 22 067 U1 as well as the DE 25 34 748 A1 known.

The present invention has for its object to provide a combination of containers, which acts by their design and the nature of their usability, for example by means of the enclosed in the additional container product promotion and thereby has sufficient stability.

This object of the invention is achieved in that the basic container each has at its spaced apart holding means and these project beyond the container shell to the outside, wherein a first holding means is formed in the container bottom by an at least partially over the circumference arranged first grid elevation, and that the additional container in the overlapping region has a first catch recess formed opposite the first grid elevation and forms a second grid elevation on the side remote from the base receptacle and the mantle-like outer part is deflected in the direction of the longitudinal axis between the second grid elevation of the additional receptacle and the base receptacle on the floor area Side arranged second holding means extends and is supported both on the second grid elevation of the additional container and on the second holding means of the base container.

The resulting from the features of claim 1 advantage is that when located in the coupling position basic container and additional container unhindered insight into the receiving space formed there is possible. This is achieved when the additional container is formed from a translucent or transparent material in a variety of manufacturing methods. In this case, the additional container forms a further holding means for the enveloping element, whereby a clear positioning between the further holding means of the additional container and the holding means is provided on the base container for the enveloping element. In addition, a protection against unauthorized removal of the additional container from the basic container is achieved by this enclosure with the enveloping element, without the entire container combination is covered by the enveloping element. Due to the known cover with the shrink film had to be driven in the printing and positioning the same great effort, on the one hand not to hinder a secure grip on the container parts and the other hand, the free view of the additional container. Furthermore, this also opens up the possibility, for example, to vary the dimensions of the additional container in the region of its receiving space while maintaining the geometry of the base container, since the enveloping element and its positioning between the holding means provided for this purpose can be maintained unchanged. In order for additional containers with different heights and associated different receiving volume can be coupled with each identically designed overlap area to the basic container without a change of the Hüllelements is necessary. Moreover, the stability of the basic container in the region of its container shell is also increased, resulting in very small wall thicknesses in this section The Auslangen can be found and so in turn raw materials can be saved.

Also advantageous is an embodiment according to claim 2, characterized in that a continuous full investment over the entire circumference of the two coupled container parts can be created and so with appropriate bias a dense and possibly also hygienic completion of the receiving space of the additional container until the removal of the same from the basic container is achievable.

It is also advantageous embodiment according to claim 3, since in the region of the open end not only the possibility of a hygienically sealed closure of the interior of the base container is created, but also the power transmission from the sealing flange is improved on the coat-like sheath element.

Due to the construction according to claim 4, it is possible that the demolding of the base container facilitates and subsequently the stackability is improved.

According to another embodiment variant according to claim 5 or 6, a predefined stack height of stacked base containers is achieved without these thereby abut each other in the area of their container shell, otherwise the unstacking can be performed by mechanical means only very difficult or secured with great effort , In addition, however, a better power transmission, starting from the shell-like Hüllelement towards the holding means achieved. Furthermore, this also allows a minimal axial compression of the base container, so that the two spaced apart in the direction of the longitudinal axis end portions of the Hüllelements for power transmission to the designated holding means or grid surveys come to rest safely.

Also advantageous is a development according to claim 7, as seen by the carrying capacity of the container combination in the direction of the longitudinal axis, can be additionally increased.

In the embodiment according to claim 8 or 9 is advantageous that thereby a flange abutting support surface is created and thus higher loads can be transmitted in this area, without causing damage to the base tank occurs.

Through the development according to claim 10 ensures that so material resources can be saved and only on the necessary tightness of the interior of the basic container Care must be taken because the derivative of the compressive force is transmitted to the outer casing element.

By the construction according to claim 11 or 12, a sufficient strength of the additional container can be achieved with a maximum receiving volume. Furthermore, but this can be achieved almost no-load transfer on the container wall of the additional container. In addition, however, a sufficient footprint of the additional container is created.

Also advantageous is an embodiment according to claim 13, characterized in that the joining process between the two container parts can be facilitated without thereby the coupling or clamping action between the two engaging container parts is adversely affected.

According to one embodiment, as described in claim 14 or 15, the design possibility of the entire container combination can be substantially increased, depending on the choice of material for the outer part of different levels stacking forces can be transmitted from the entire container combination seen in the direction of the longitudinal axis. But this is also the container combination adaptable to different operation operations. Furthermore, it can also be used to improve the quality of the printed image on the enveloping element, since the printing process can be carried out in a flat surface.

In this case, an embodiment according to claim 16 proves advantageous, since a secure originality reference is created by the deliberately carried out detachment of the shell-like outer part. In addition, the separation of the Hüllelements is facilitated at a predetermined for much easier.

Finally, however, an embodiment as described in claim 17 is possible because it can be created cost-effective in large quantities manufacturable container parts.

The invention will be explained in more detail below with reference to the embodiments illustrated in the drawings.

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

In the Fig. 1 to 3 a container combination 1 is shown, which is composed of several individual parts or components or formed. Thus, here the container combination 1 shown comprises at least two container parts, which by a in the Fig. 1 Basic container 2 shown above and an additional container 3 arranged underneath is formed. The two container parts, namely the basic container 2 and the additional container 3, are arranged one above the other, and releasably connected to each other.

The basic container 2 in turn has a container casing 4, a container bottom 5, as well in the direction of a longitudinal axis 6 spaced apart ends 7, 8. In the basic container 2 shown here is a preferably thermoformed, cup-shaped receiving part, wherein the first end 7 has a receiving opening and the other end 8 is closed by the container bottom 5 in a known manner. The container casing 4 is usually designed to taper conically starting from the end 7 open here in the direction of the further end 8 or the container bottom 5. The cross-sectional shape of the base container 2 may be freely formed according to the known prior art, such as round, square, rectangular, polygonal, oval or similar.

The additional container 3, in turn, likewise has a container jacket 9, a container bottom 10, and end 11, 12 distanced from one another in the direction of the longitudinal axis 6. The additional container 3 is also cup-shaped and adapted in its cross-section to that of the base container, wherein the end 11 is also formed open.

The additional container 3 engages with its base container 2 facing and open here formed end 11 in an overlap region 13, the end 8 with the container bottom 5 of the base container 2 in the direction of its container shell 4. By this overlapping the container shell 9 of the additional container 3 is at corresponding, mutual Forming the mutually engaging portions created a coupling device between these two container parts, which will be described in more detail below.

The base container 2 has in each case at its mutually distanced ends 7, 8 holding means 14, 15, which project beyond the container shell 4 to the outside, ie on the side remote from the longitudinal axis 6 side. The first holding means 14 is provided in the region of the container bottom 5 and formed by an at least partially over the circumference arranged first grid elevation 16. The first holding means 14 or the first grid elevation 16 formed on the base container 2 can be formed by a shoulder 17 running continuously over the circumference. The second holding means 15 formed on the base container 2 can be formed in a known manner by a sealing flange 18 or sealing edge formed continuously over the circumference. At this sealing flange 18, a closure element can be sealed after filling the interior of the base container 2, so as to provide a hygienic tight seal against the external environmental conditions, which, however, is not shown.

The container shell 4 of the base container 2 comprises, starting from the second holding means 15 or the open end 7, toward the first holding means 14 in the region of the container bottom 5 a conically tapered wall portion 19, which includes a first inclination angle 20 to the longitudinal axis 6. Furthermore, the container casing 4 of the base container 2 comprises a further wall part 21 which, starting from the first holding means 14 in the region of the container bottom 5, has a rear extension 23 projecting into an interior 22 and a shoulder 24 connecting the rear extension 23 to the first wall part 19. This paragraph 24 forms in a known manner a stack edge, wherein in a plurality of superposed base containers 2, the shoulder 17 formed by the grid elevation 16 of the inserted cup is supported on this and so a mutual clamping of superposed base containers 2 is avoided. In this case, preferably the rear pull 23 and the shoulder 24 are designed to run continuously over the circumference of the base container 2.

The additional container 3 has in turn in the overlap region 13 a counter to the first grid elevation 16 of the base container 2 formed first latching recess 25. This in turn forms due to the small wall thickness of the container shell 9 on the side facing away from the base container 2 side, a second grid elevation 26. Furthermore, the container jacket 9 of the additional container 2 in the overlapping region 13 is preferably formed on the further wall part 21 of the base container 2 forming the rear pull 23, at least in regions. For better support and force transmission directed at the sealing flange 18 in the direction of the longitudinal axis 6 axial forces, it is advantageous if the container shell 9 of the additional container 2 at the base container 2 facing open end 11, a container jacket 9 outwardly projecting support flange 27 formed or is provided. The geometry of the support flange 27 may be selected so that it is formed in the coupled state of the two container parts, on which formed by the further wall portion 21 of the base container 2 paragraph 24 fitting. The shoulder 24 and the support flange 27 are aligned approximately in the vertical direction with respect to the longitudinal axis 6. The angled design of the support flange 27 sharp edge edges are avoided, thereby achieving a more favorable force or force transmission between the container parts.

How best of the Fig. 1 can be seen, includes the container shell 9 of the additional container 3 with the longitudinal axis 6, a second inclination angle 28, which with respect to the first Inclination angle 20 of the first wall portion 19 of the base container 2 is smaller. This selected, smaller second inclination angle 28 corresponds approximately to an inclination angle of the rear section 23 of the base container 2. It is also possible that the container shell 9 of the additional container 3 in the overlap region 13 with the base container 2 with the longitudinal axis 6 includes a further inclination angle 31 , which is chosen slightly larger in terms of the angle of inclination 28 of the rear pull 23 of the base container 2 - see Fig. 3 , Thus, the wall portion of the container casing 9 from 9 starting from the container bottom 10 to the recess 25 have the smaller inclination angle 28 relative to the further inclination angle 31 of the further wall portion between the recess 25 and the open end 11.

How best of all from the Fig. 1 can be seen, the container combination 1 also includes at least one enclosing the container parts Hüllelement 29, which is formed like a coat. This coat-like envelope element 29 is designed as an outer part 30 which runs through the circumference and which is viewed in the direction of the longitudinal axis 6 between the second grid elevation 26 of the additional container 3 and the holding means arranged on the base container 2 on the side facing away from the container bottom 5 or from the bottom area 15, such as the sealing flange 18, extends and is supported on these. By cooperating with each other Rastausnehmung 25 of the additional container 3 with the grid elevation 16 of the base container 2 and subsequently by the support of the outer part 30 at the second grid elevation 26 of the additional container 3 takes place in this coupling region a good and above all safe sustainable power transmission of compressive forces starting from Second holding means 15 and the sealing flange 18 in the direction of the longitudinal axis 6 toward the container bottom 10 of the additional container 3. This can be dispensed with additional loads abtragende stacking aids or stacking receptacles between a plurality of stacked container combinations 1. Thus, for example, with simple pallets Auslangen be found because the pressure forces between the individual pallets or pads alone by the container combination 1, in particular the container shells 4, 9 and the sheath member 29, is transmitted, even if several of these are arranged one above the other.

The shell-like outer part 30 may be formed from a paper and / or cardboard material or else from a plastic film and be printed on the outside and / or inside. To produce the shell-like outer part 30 can be a blank to a coat be wrapped. Subsequently, the mutually facing end portions are glued together. This tubular outer part 30 is then mounted on the superimposed and coupled together container parts between the holding means, in particular the sealing flange 18 and the further grid elevation 26. This can be done either by pushing over the closed outer part 30 or by wrapping the container parts with the outer part 30. When wrapping, the bonding between the mutually facing end portions of the outer member 30 is made directly in this process. It is essential that the outer part is supported on the holding means provided for this purpose.

By attaching to the container shell 4 of the base container 2 reinforcing Hüllelements 29, at least the first wall portion 19 of the container shell 4 of the base container 2 have a smaller wall thickness with respect to a wall thickness of the container shell 9 of the additional container 3. In this case, the container shell 4 of the base container 2 serves for liquid or gas-tight storage of introduced in the interior 22 food product, wherein the enveloping element 29 forms the support or support function for the basic container 2.

The overlapping area 13 between the basic container 2 and the additional container 3 forms a kind of coupling device between these two container parts. The coat-like sheath element 29 wraps around not only the basic container 2, but also the additional container 3 in the region of that wall portion which is arranged starting from the second grid elevation 26 towards the open end 11 extending side. Through this wrapping a kind of tamper evidence is achieved, which is immediately recognizable, whether from the additional container 3 stockpiled media or articles, such as collecting pictures, gifts, toys and games for children, recipes, especially preparation recipes, or cards for competitions, Accessories, cutlery or additives for the stored in the interior 22 of the base container 2 food or the like are unchanged therein.

A decrease of the additional container 3 from the base container 2 is possible when the enveloping element 29 is knowingly removed by the user. In this case, the shell-like outer part 30 or the enveloping element 29 may have a predetermined separation strip formed in a known manner, as this example in the EP 0 408 515 B1 or the US 5,025,981 A described and protected. In order to avoid unnecessary repetition, is for the formation of the predetermined separation strip on the corresponding disclosure in the aforementioned Reference is made to references.

In order to obtain a sufficient light protection of the stored in the interior 22 of the base container 2 food product, preferably an opaque material for forming the same is selected. An additional light and UV protection is also achieved by the shell-like envelope element 29 or outer part 30. In order to ensure an insight into the receiving space of the additional container 3, this is preferably formed of a transparent or or even completely transparent material, so as to be able to see the content immediately and clearly at first glance.

In the Fig. 4 are several, in this case two, one above the other arranged container combinations 1 shown, wherein the container combination shown above 1 with the container bottom 10 of the additional container 3 is supported on the container bottom 5 of the underlying base container 2 of the further container combination 1 and rests against it. A support over the previously described stacking edges paragraphs 24, as has been described for the basic container 2, does not take place here. Nevertheless, this also creates a relatively space-saving stacking possibility, without requiring too much space is needed. In this preassembled state of the container combination 1, the corresponding medium or agent is already introduced or inserted in the receiving space formed by the additional container 3, since the originality assurance has already been provided by the arranged enveloping element 29 or the outer part 30.

A simple production of the container parts is achieved when at least one of the two container parts, namely the basic container 2 and / or the additional container 3, is thermoformed from a thermoformable film. But it would also be possible to produce at least one of the container parts by an injection molding process. If, for example, the base container 2 is thermoformed from a film or a foil composite, the additional container 3 can be produced by injection molding. In the case of injection molding, it is also possible to produce larger wall thicknesses or wall thicknesses of the container jacket 9 or the container bottom 10 that are different from one another in a simple way. As a result, in turn, the carrying capacity in the direction of the longitudinal axis 6 is increased despite the smaller cross-sectional dimension in the region of the container jacket 9 compared to the base container 2. In combination of the container shell 4 of the base container 2 with the smaller wall thickness and the enveloping element 29th or the outer part 30 and the stably designed additional container 3, an increased stability of the entire container combination 1 over previous embodiments is achieved.

The embodiments show possible embodiments of the container combination 1, wherein it should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but also various combinations of the individual embodiments are possible with each other and this possibility of variation due to the teaching of technical action representational invention in the skill of those skilled in this technical field. So are all conceivable embodiments, which are possible by combinations of individual details of the illustrated and described embodiment variant, includes the scope of protection.

For the sake of order, it should finally be pointed out that, for a better understanding of the construction of the container combination, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.

The problem underlying the independent inventive solutions can be taken from the description.
