Description

The present invention relates to an erectable packaging unit comprising at least one outer packaging element made of cardboard, which is convertible from an approximately flat lying storage state to a use state in which the outer packaging element has approximately the basic shape of a multi-sided prism, and further comprising at least one of the outer packaging element received inner packaging element of a liquid-tight flexible material, wherein the at least one outer packaging element after forming in use a container forms with side container walls and a container bottom.

From the prior art, a packaging product has become known recently, which was presented to the public on April 17, 2012 and which is advertised on the Internet by the company Nestle, at the address http://www.nestle.de/presse/Presseinformationen/Pages/2012_04_17_K%C3%B6stlicher_Suppengenuss_in_nur_einem_Moment_br_Maggi_Moment_Mahl__die_erste_Instantsuppe_im_praktis.asp

It is a composite packaging for example, soup soups, which is laid flat in the transport state and can be folded into a state of use to a container. The fact that the inner packaging element is made of a liquid-tight composite material, you can pour a hot liquid in the unfolded to the container packaging. For example, the package may contain an instant soup powder, and thus a ready-made soup may be prepared which the user can drink directly from the container.

The object of the present invention is to provide an erectable packaging unit of the type mentioned, which provides the user with a similar functionality, but in the unfolded state of use has greater stability and better stability.

The solution to this problem provides an erectable packaging unit of the aforementioned type with the characterizing features of claim 1.

According to the invention, the cardboard part of the packaging unit is formed in at least two parts and has at least two telescopically received and mutually displaceable cardboard elements, namely a first outer cardboard element and a second inner cardboard element, wherein the container bottom is formed from the second inner cardboard element and wherein the inner Packing element is inserted from the flexible material in the second inner cardboard element and is fixed thereto.

In the solution according to the invention so instead of only a single cardboard element, which simultaneously formed the container walls and the container bottom in the art, now two cardboard elements are provided which are telescopically guided into each other and are mutually displaceable when the container erected from the flat position and in the state of use is transferred. Thus, in use, both carton elements form, as it were, an all-round double container wall, in which the inner carton element engages in the outer carton element and overlaps it. This results in a double-walled container that is stiffer and has better stability.

Also, the erection of the container according to the invention from the flat non-use state to the use state follows a different kinematics and therefore has advantages. While in the prior art the container for erecting the narrow sides is pressed inwards and thereby pivot the later forming the bottom segments of the single cardboard element by the thrust of the side wall elements, with which they are connected in the ground plane, takes place in the container according to the invention the folding over of the floor segments by inserting the second inner cardboard element in the direction of the container axis (ie perpendicular to the plane of the subsequent floor) into the first outer cardboard element. This results in a guide of the inner cardboard element in the outer carton element, which facilitates the movement of the erection and thereby stabilizes the container. The user exercises the pressure on the packaging from the top and bottom to erect by pushing the two cardboard elements into each other.

According to a preferred embodiment of the invention, it is provided that the second inner cardboard element for each side wall of the prism each having an approximately rectangular upper wall portion, respectively one hingedly connected to this upper wall portion central thrust portion, and each one hinged to the middle thrust section lower bottom portion, which forms a segment of the container bottom in the erected state of use of the packaging.

The number of side walls of the prismatic container is arbitrary in principle. For example, these may be three, four, five, six or more sidewalls. In the latter case, therefore, the erected container forms a hexagonal Prism. According to a preferred variant of the invention, it can be assumed for the second inner cardboard element of a single folding blank, which then comprises the corresponding number of the upper rectangular wall sections, the middle thrust sections and the lower floor sections for all side walls of the prism. The folding blank is correspondingly edged or grooved where there are connecting lines between the individual wall sections which are to form articulated bending edges later in use. The articulation of the middle thrust sections and the lower floor sections of the second inner carton element can be achieved by corresponding cutouts in the Faltzuschnitt, as well as the independence of the individual bottom sections, which move radially inwardly when erecting the container like segments and preferably overlap partially when forming the container bottom can.

Preferably, the middle thrust sections and / or the lower bottom sections of the second inner carton element are approximately trapezoidal in outline and the carton blank of the second inner carton element has approximately triangular cutouts in addition to the thrust sections and the bottom sections.

The carton blank of the second inner carton element may be, for example, such that the middle push sections and the lower bottom sections of the second inner carton element each pivot in the opposite direction of rotation when erecting the prism forming the container. For example, during the telescoping movement of the second inner cardboard element into the first outer cardboard element, the middle push sections in each case slide radially inwardly, with the lower floor sections also respectively sliding radially inward, the hinge axis in each case in the connection region, in particular in the region of a bending edge between the middle push section and the lower floor section is located.

The inner packaging element made of the flexible material may, for example, consist of a film-like composite material and form in the erected package a kind of bag which serves to make the interior of the erected container liquid-tight in use. This can for example be attached to the second inner cardboard element such that it overlaps the approximately rectangular upper wall sections of the second inner cardboard element on the inside (partially) and thus lines the cardboard material inside.

In order for the second inner carton element to slide telescopically into the first outer carton element, the upper wall sections of the inner carton element must be able to slide freely in a guided movement in the corresponding wall sections of the outer carton element. In order nevertheless to create a mutual fixing of the second inner cardboard element on the first outer cardboard element, one can, for example, connect the lower floor sections of the second inner cardboard element respectively in their lower or radially outer regions with the first outer cardboard element. Both carton elements are then connected to one another only in the radially outer bottom region of the container, which corresponds in each case to the lower end region of the wall sections of the outer carton element and to the lower end region of the lower bottom sections of the inner carton element. There you can, for example, both cardboard sections overlap slightly and glue them, wherein one can provide a bending edge on the inner carton element, so that the bottom portions when erecting the container can move in an articulated manner inwardly in a folding movement radially inwardly and downwardly, so as the container bottom train.

According to a preferred development of the invention, mutually corresponding locking elements may be provided on the first outer carton element and on the second inner carton element, lockingly interlocking with each other in a lower end position of the second inner carton element inserted in the first outer carton element. These locking elements may for example be slots, tabs formed by tabs or the like.

The features described in the dependent claims relate to preferred developments of the task solution according to the invention. Further advantages of the present invention will become apparent from the following detailed description.

Hereinafter, the present invention will be explained in more detail by means of embodiments with reference to the accompanying drawings. Showing:

1 a perspective view of an exemplary packaging unit according to the invention in an intermediate position between flat non-use position and upright position of use;

2 a view of the folding blank for the second inner cardboard element;

3 a view of the folding blank for the first outer carton element;

4 a blank for the bag-like packaging element of the sheet-like flexible composite material;

5 a schematically simplified representation of the manufacturing process of a packaging unit according to the invention from the individual packaging elements.

First, on the 1 Referenced. The drawing shows an example of a packaging unit according to the invention 10 in the partially erect state. One recognizes the first outer cardboard element 11 and the second inner carton element partially telescoped into this 12 , The further this in the first outer carton element 11 is pushed into it, the more spread the ground segments, gradually lie in a horizontal position and form the container bottom, whereas when erecting by inserting the second inner cardboard element 12 in the first outer carton element 11 shortens the axial length of the container. The container containing the packaging unit 10 forms in the embodiment, a hexagonal prismatic shape with six in outline approximately rectangular container walls, in their areas, the two cardboard elements 12 (inside) and 11 (outside) overlap, resulting in a stiffening of the container. If, on the other hand, you pull the inner cardboard element 12 from the outer carton element 11 out, the packaging unit can lay flat and it results in a flat non-use or storage condition.

In the erected state becomes the second inner carton element 12 lined by a film-like liquid-tight inner packaging element 13 , which forms a kind of inner bag and at the same time spans its bottom area when erecting the container, so that in the use state of the container through this inner bag (packaging element 13 ) is lined liquid-tight and you can pour a liquid in the packaging. This makes it possible to use them for example as a soup cup, coffee cup, teacup, cup for other hot drinks, etc. or for mixing liquid or viscous mixtures, for example for applications in the building material sector or the like. It is also possible, for example, the inner bag over the upper edge of the second inner cardboard element 12 Move outwards, so that this edge region is also dressed on the outside of a liquid-tight material. This has an advantage in terms of hygiene protection, since the user can then drink directly from the cup without coming into direct contact with the cardboard material.

Outside of the container is at least one tab 14 provided for gripping, for example, by folding and gluing from the carton blank of the first and / or the second carton element 11 . 12 can be formed, as will be explained in more detail below with reference to the carton blanks. In the lower region of the side walls of the container are respectively locking elements 15 formed, one of which in 1 only those can recognize that are attached to the first outer carton element 11 are located. On the second inner carton element 12 are corresponding locking elements which engage in the locking elements of the first outer carton element when an end position is reached with fully erected container so that it is secured in the erected position of use by a mutual positional fixation of the two cardboard elements 11 and 12 ,

It will now be following the 2 Reference is made and based on this, the carton blank of the second inner carton element 12 explained in more detail. The carton blank comprises a total of six identically shaped segments, each longitudinally over bending edges 124 are interconnected and each forming in the finished container, the inner layers of the six side walls of the six-sided prism. Each of these six segments, as seen in the longitudinal direction (that is to say in the case of the later prismatic container in the axial direction of the prism), comprises successively first rectangular upper wall sections 121 , with these in each case over transversely extending bending edges 126 connected in outline trapezoidal mean thrust sections 122 , with these in turn via transversely extending bending edges 127 connected, also in outline trapezoidal lower floor sections 123 as well as with these over bending edges 128 bonded adhesive edge sections 125 , The latter serve to the second inner carton element 12 later with the first outer carton element 11 to connect, for example, by gluing. They are also vertically aligned in the erected condition of the container, while the lower bottom portions 123 Align horizontally and partially overlapping similar to an iris diaphragm push each other while simultaneously pivot radially inward in the ground plane.

In addition to the trapezoidal average thrust sections in outline 122 are in each case to the adjacent segment in outline triangular cutouts 129 in the blank of the inner cardboard element 12 to the mobility of the middle thrust sections 122 to ensure. Also located next to the trapezoidal lower bottom sections in outline 123 triangular cutouts in each case towards the adjacent segment 129a to the articulated mobility of the lower floor sections 123 to accomplish. In addition, are still in the Range of bending edges 126 at the middle thrust sections 122 smaller roughly rectangular cutouts 122 a, when erecting the container, the locking elements of the second inner cardboard element 12 form, which in the corresponding locking elements of the first outer carton element 11 engage, as below in the description of the carton blank for the outer carton element 11 is explained.

The second inner carton element 12 also has one next to an outer rectangular wall section 121 arranged, in length corresponding but narrower adhesive flap 121 that serves the second carton element 12 close to the perimeter. In this case, the second cardboard element 12 from the in 2 folded blank is folded into a prismatic body and then the adhesive flap 121 with the wall section located at the other end of the blank 121 glued and so is the cardboard element 12 closed at the circumference.

The following is with reference to 3 the carton blank for the first outer carton element 11 explained in more detail. This consists of six adjacent in the later circumferential direction of the container in outline rectangular wall sections 111 , each in the circumferential direction, that is, along its longitudinal edges by bending edges 112 connected to each other. At the outermost two wall sections 111 are each outside over bending edges 114 tab members 113 attached, which may be formed on the outside arc-shaped in outline, as in the example, but also in principle may have a rectangular outline shape. These two tab elements 113 can be glued together flat in the manufacture of the container and then form a tab on which you can touch the upright container (see also 1 .)

It can be formed according to a variant of the invention, two such tabs on which one can touch the container, including, for example, the outer carton element 11 can produce from a two-piece blank, each of which half of the wall sections 111 and then wherein each part of the blank with two tab elements 113 is provided, which can then be glued together.

The first outer carton element can thus be made of the in 3 carton blank simply fold to a six-sided prism whose side walls through the six wall sections 111 the carton blank are formed. In principle, the carton blank forms the carton element 11 the settlement of such a six-sided prismatic container, which is open at the top and bottom. The two tab elements 113 lie then after folding outside the prismatic container and lie with their faces to each other.

The following is with reference to 4 the blank for the inner bag-like packaging element 13 from the liquid-tight composite material, which in the finished container the second inner carton element 12 lined on the inside and so makes liquid-tight. This packaging element 13 For example, in the second inner cardboard element 12 be glued in sections and are firmly connected in this way with this, so that when telescoping the inner cardboard element 12 in the outer carton element 11 into it, for erecting the container, the inner packaging element 13 taken and stretched - it consists of a flexible material.

From the in 4 The blank shown becomes the flexible packaging element 13 so folded and glued that the two trapezoidal middle segments 131 . 132 forming the bottom portion of the later bag and the two transversely central and longitudinally outer rectangular segments 133 . 134 together with each of the two laterally adjacent thereto, in the transverse direction outer and in the longitudinal direction outer, adjacent trapezoidal segments 135 . 136 each form the side wall portions of the later bag. Between each adjacent rectangular and trapezoidal segments are in 4 each lines 137 drawn for orientation and to understand the relative position of the areas of the bag in the finished state of the container. So that later the bag 13 in the second inner carton element 12 folds when erecting the container accordingly, is no attachment of fold lines in the blank of the flexible packaging element 13 necessary.

In the transversely outer and longitudinally central areas are a total of eight pairs of adjacent triangular segments 138 , which are each in pairs congruent with each other, can be superimposed and glued, so that they lie in finished bag-like container outside the inner volume of the container. The two trapezoidal middle segments 131 . 132 lie after the folding and bonding of the bag-like container initially to each other, such that the fold line 139 projects into the container between these two segments, so that when pushing the inner cardboard element into each other 12 from these two segments 131 . 132 formed bottom area of the bag is taken and can span.

Hereinafter, referring to the schematic illustrations of 5 the process of producing the packaging unit from the two previously described cardboard elements 11 and 12 as well as the flexible bag-like inner packaging element 13 explained in more detail. In the first upper sketch is initially only the blank of the first outer cardboard element 11 represented, from which is assumed. This is now the second inner cardboard element in the production in the machine 12 designed so that both cardboard elements 11 . 12 one above the other and overlap, the cardboard element 12 with the middle thrust sections 122 and the lower floor sections 123 on the cardboard element 11 lies and the rectangular upper wall sections 121 the outline of the first cardboard element 11 towering outwards, as in the second sketch of 5 is shown. There are also those areas 16 drawn in which adhesive is applied. The two cardboard elements 11 . 12 lie one above the other so that the respective segments of the later six side walls are superimposed.

In the third sketch of 5 is now the flexible bag-like packaging element 13 for the inner lining of the container on the second inner cardboard element 12 unbalanced in such a way that it is the three outer of the rectangular upper wall sections 121 the cardboard element 12 overlaps. One recognizes the adhesive flap in this third sketch 121 a of the second cardboard element 12 , which is folded in the fourth sketch and serves to close the second inner carton element after folding by gluing the periphery. The flexible bag-like packaging element 13 is about the adhesive surfaces 16 (see second sketch in 5 ) with the second inner carton element 12 connected.

Starting from the fourth sketch then both the first outer cardboard element 11 as well as the second inner carton element 12 Folded around a central axis, extending along a central bending edge 124m respectively. 112m extends (see 2 and 3 ), so that then the two tab elements 113 the first outer carton element 11 lie on each other and can be glued together to form a tab. The flexible bag-like packaging element 13 then lies partially within the upper rectangular wall sections 121 the second inner carton element 12 , which in turn in the first outer carton element 11 lies. From this flat non-use state can then the second inner cardboard element 12 in the direction of the fifth sketch of the 5 marked longitudinal axis 17 in the first outer carton element 11 be pushed telescopically to erect the container in a position of use (see also the perspective view of 1 .)
