Description

• Der schalenförmige Träger („Tray“) weist eine Bodenwand, von den seitlichen Rändern der Bodenwand hochstehende Seitenwände und einen Trennsteg auf, der sich zwischen zwei einander gegenüberliegenden Seitenwänden erstreckt. Die Seitenwände und die Bodenwand bilden eine Schale, die durch den Trennsteg in Abteilungen unterteilt wird, in die Ware einsetzbar ist. Der Träger ist insbesondere zur Aufnahme stückiger oder dickflüssiger Ware vielfältiger Art geeignet, wie beispielsweise Schokoladentäfelchen, Kekse oder andere Süßwaren, Gemüse, Kräuter oder Obst, Pommes Frites und Mayonnaise oder Ketchup, Schrauben, Muttern, Dübel oder andere Befestigungsmittel, Bleistifte, Kreiden oder andere Schreibutensilien.

The invention relates to a shell-shaped carrier made of cardboard, cardboard or another foldable flat material:

• The shell-shaped carrier (“tray”) has a bottom wall, side walls protruding from the side edges of the bottom wall, and a separating web that extends between two opposing side walls. The side walls and the bottom wall form a shell, which is divided into compartments by the separator, into which the goods can be inserted. The carrier is particularly suitable for holding lumpy or viscous goods of various kinds, such as chocolate bars, cookies or other confectionery, vegetables, herbs or fruit, French fries and mayonnaise or ketchup, screws, nuts, dowels or other fasteners, pencils, chalks or others Writing utensils.

The EP 3 095 722 B1 describes a packaging for food, in particular for snacks, made of cardboard in the form of a tray with a base, two side walls, a front wall and a rear wall and a partition part which is connected to the side walls at the side edges via connecting strips which comprise several folding parts and is connected at the lower edge to an inner cover of the floor on one side of the partition wall part. The inner cover of the base is connected by a fold line to an inner cover of the front wall, which in turn is connected to the upper edge of the front wall by a fold line. The packaging can be completely pre-glued at the folding box manufacturer and the folding parts allow the partition part to be folded flat against the top of the bottom wall. The side walls and the front walls are inclined slightly outwards. In this state, the packaging can be nested and thus stored and transported in a space-saving manner. For filling, the packaging is removed from the stack and the partition part is opened. The various compartments can then be filled separately from one another. The disadvantage is that the packaging is not well suited for the automatic pre-assembly before nesting and the automatic erection before filling and the construction limits the speed of the automatic processing. Another disadvantage is that the construction has adhesions, which impairs the recycling of the cardboard.

The invention is based on the object of creating a shell-shaped carrier made of foldable flat material with a separating web, which is better suited for automatic production and processing. The reusability of the carrier should preferably also be improved.

The object is achieved by a shell-shaped carrier with the features of claim 1. Advantageous embodiments of the carrier are specified in the subclaims.

• • eine Bodenwand,
• • Seitenwände, die über erste Faltlinien an ihren unteren Rändern mit den seitlichen Rändern der Bodenwand verbunden sind und die von der Bodenwand hochstehen,
• • erste Verbindungsstreifen, die jeweils über eine zweite Faltlinie an ihrem oberen Rand mit dem oberen Rand einer Seitenwand verbunden sind und die an den Innenseiten der damit verbundenen Seitenwände anliegen, wobei Seitenwände, die an den oberen Rändern mit ersten Verbindungstreifen verbunden sind, einander gegenüberliegen,
• • zweite Verbindungstreifen, die jeweils über eine dritte Faltlinie an einem ersten seitlichen Rand mit dem unteren Rand eines ersten Verbindungstreifens verbunden sind und die an der Oberseite der Bodenwand anliegen, und
• • Trennstege, die jeweils über eine vierte Faltlinie mit einem zweiten seitlichen Rand eines zweiten Verbindungstreifens verbunden sind, wobei die Mittelstege von den zweiten Verbindungstreifen hochstehen und aneinander anliegen.

The shell-shaped carrier according to the invention made of cardboard, cardboard or some other foldable flat material comprises

• • a bottom wall,
• • Side walls that are connected to the side edges of the bottom wall by first folding lines at their lower edges and that protrude from the bottom wall,
• • first connecting strips which are each connected to the upper edge of a side wall via a second fold line at their upper edge and which rest against the inner sides of the side walls connected thereto, with side walls which are connected to the upper edges with first connecting strips lying opposite one another,
• • second connecting strips, which are each connected to the lower edge of a first connecting strip via a third fold line at a first lateral edge and which lie against the top of the bottom wall, and
• • Separating webs which are each connected via a fourth fold line to a second lateral edge of a second connecting strip, the central webs standing up from the second connecting strips and resting against one another.

The carrier according to the invention can be formed from a single blank of foldable flat material. It can be prefabricated by the folding box manufacturer by erecting the side walls so that a first connecting strip, the second connecting strip and the connecting web connected to it stand up from two opposing side walls in continuation of the same. In this state, the carrier can be stabilized by connections between the side walls, which are produced, for example, by hooking or gluing corner connection tabs to the side edges of adjacent side walls. In an embodiment with slightly outwardly inclined side walls, a large number of pre-assembled carriers can be nested and transported. At the manufacturer or packer of the product to be used in the carrier, the first connecting strips are each around the second folding line against the side wall connected to it, in the opposite direction the second connecting strips are each around the third folding line against the top of the bottom wall, the dividers are each around the fourth folding line in perpendicular to the connecting strip connected to it, and become the dividers brought together in plant. As a result, the separating webs are supported on one another and are fixed in the position in which they separate two compartments in the shell from one another. The pre-assembly and the complete erection of the carrier can be done by simple folding, which can be carried out at high speed by automatic machines. It is advantageous that when the prefabricated carrier is fully erected, adhesions can be dispensed with, since the separating webs and the first and second connecting strips connected to them are held in the fully erected position by being supported on one another.

The separating webs are preferably folded around the fourth fold lines and the second connection strips are folded around the third fold lines and, at the same time or afterwards, the first connection strips are folded around the second fold lines. As a result, the first connecting strips come into contact with the inside of the side walls, the second connection strips come into contact with the top of the bottom wall and the separating webs come into contact with one another.

According to one embodiment of the invention, the first lateral edges of the second connection strip run perpendicular to the second lateral edges of the second connection strip. In this embodiment, the fourth fold lines and the third fold lines are aligned perpendicular to one another, so that the folds of the separating webs and the folds of the connecting strips take place in mutually perpendicular directions.

In another embodiment, the first side edges and the second side edges of the second connecting strips run parallel to one another. In this embodiment, the fourth and third fold lines are arranged parallel to one another, so that the folds of the separating webs and the second connecting strips take place about axes that are parallel to one another.

According to a further embodiment, the side walls are inclined outwardly with respect to the bottom wall, so that the carriers can be nested in one another in a pre-assembled arrangement in which the first and second connecting strips are each aligned in the same plane as the side walls connected to them via the second folding lines. According to a further embodiment, the side walls have a trapezoidal contour that widens towards the top.

According to a further embodiment, the second connecting strips have outwardly projecting tabs within interruptions of the fourth folding lines, which are separated by cut lines from the separating webs which extend between the ends of the fourth folding lines adjoining the tabs. When the dividing webs are folded around the fourth fold lines up to their perpendicular alignment to the connecting strips, openings with contours corresponding to the noses open between the noses and the dividing webs. One nose covers the other nose, engages in the opening released by this and is supported on the edge of the opening released by the other nose in the separating web.

According to a further embodiment, some of the side walls are connected at the side edges via fifth fold lines with corner connecting tabs which rest against the respective adjacent side walls. The shell formed from the bottom wall and the side walls can be stabilized by means of the corner connection straps. According to a further embodiment, the corner connection tabs are trapezoidal. This favors low-loss production.

According to a further embodiment, the corner connecting tabs are glued to the adjacent side walls and / or clamped, hooked or otherwise fixed between the adjacent side walls and the first connecting strip. This stabilizes the carrier in the shell shape. This stabilization can take place with and / or without gluing.

According to a further embodiment, the first connecting strips are connected at the outer ends of the lower edges via sixth folding lines to lateral retaining tabs which are fixed between the second connecting strips and the bottom wall.

According to a further embodiment, the side walls which adjoin the lateral edges of the dividing webs have no direct connection to the dividing webs. This reduces the cost of materials and makes it easier to erect the carrier.

According to a further embodiment, the carrier has a cover on the side opposite the bottom wall. Products inserted into the carrier can be protected by the cover. According to a further embodiment, the cover is a hood-like lid attached to an upper edge of a side wall or hinged to an upper edge of a side wall via a sixth fold line, a sleeve or a slipcase into which the carrier is inserted, or a folding box into which the carrier is inserted is used.

In the present application, the information “above” and “below” relate to a completely erected, shell-shaped carrier, which is placed with the underside of the bottom wall on a horizontal substrate, so that the side walls extend upwards away from the substrate.

The carrier is made from a blank of foldable flat material. According to one embodiment, the carrier is made from a one-piece blank.

According to 1 shows the cut 1.1 a rectangular bottom wall 2 and four side walls 3.1 to 3.4 on. The side walls 3.1 to 3.4 are above first fold lines 4.1 to 4.4 at their lower edges with the side edges of the bottom wall 2 connected. The side walls 3.1 to 3.4 are each trapezoidal, their width increasing with increasing distance from the first fold line 4.1 to 4.4 enlarged.

The blank also includes 1.1 first connecting strips 5.1 , 5.2 each having a second fold line 6.1 , 6.2 at their upper edges with the upper edges of a side wall 3.1 , 3.3 are connected. The top edges are the wider edges of the side walls 3.1 , 3.3 . The first connecting strips 5.1 , 5.2 are according to the side walls 3.1 , 3.3 trapezoidal so that they are around the second fold lines 6.1 , 6.2 across the board against the side walls 3.1 , 3.3 are foldable.

The blank also includes 1.1 second connecting strip 7.1 , 7.2 each having a third fold line 8.1 , 8.2 at a first lateral edge with the lower edge of one of the first connecting strips 5.1 , 5.2 are connected.

The second connecting strips 7.1 , 7.2 are in turn each about a fourth fold line 9.1 , 9.2 on a second side edge with a trapezoidal separator 10.1 , 10.2 connected. In this embodiment, the fourth fold lines extend 9.1 , 9.2 perpendicular to the third fold lines 8.1 , 8.2 . The second connecting strips 7.1 , 7.2 are rectangular with their first lateral edge being half the length of the lower edge of the first connecting strip 5.1 , 5.2 .

The second connecting strips 7.1 , 7.2 have within interruptions of the fourth fold lines 9.1 , 9.2 outwardly protruding noses 11.1 , 11.2 . The noses 11.1 , 11.2 are through die lines 12.1 , 12.2 from the dividers 10.1 , 10.2 separated, which is between the to the noses 11.1 , 11.2 adjacent ends of the fourth fold lines 9.1 , 9.2 extend.

Finally are the side walls 3.2 , 3.4 that don't have second fold lines 6.1 , 6.2 with the first connecting strip 5.1 , 5.2 connected via fifth fold lines 13.1 to 13.4 on their lateral edges with trapezoidal corner connection tabs 14.1 to 14.4 connected.

The corner connecting straps are used to erect the girder 14.1 to 14.4 around the fifth fold lines 13.1 to 13.4 around more vertically Orientation to the side walls connected to them 3.2 , 3.4 folded and all side walls 3.1 to 3.4 around the first fold lines 4.1 to 4.4 folded up until they meet at their side edges. In this orientation they are secured by gluing the corner connection tabs 14.1 to 14.4 on the insides of the adjacent side walls 3.1 , 3.3 secured.

The side walls 3.1 to 3.4 and the bottom wall 2 then form a first cup-shaped carrier which is open at the top and gradually widens towards the top 15.1 . In this configuration is the first carrier 15.1 in 2 shown. It can also be seen from this that the first connecting strips 5.1 , 5.2 in the same plane as the one above second fold lines 6.1 , 6.2 connected side walls 3.1 , 3.2 and that with it over third fold lines 8.1 , 8.2 connected second connecting strip 7.1 , 7.2 as well as the fourth fold lines 9.1 , 9.2 connected dividers 10.1 , 10.2 are arranged.

According to 3 can use a large number of such pre-assembled first carriers 15.1 Nested and stacked to save space 16 be stored.

Individual first carriers 15.1 from the pile 16 be taken. Before packing, every first carrier 15.1 completely erect. The first connecting strips are used for this 5.1 , 5.2 around the second fold lines 6.1 , 6.2 against the insides of the associated side walls 3.1 , 3.3 , the second connecting strips 7.1 , 7.2 around the third fold lines 8.1 , 8.2 folded in the opposite direction and the dividers 10.1 , 10.2 around the fourth fold lines 9.1 , 9.2 outwards in a perpendicular orientation to the second connecting strip 7.1 , 7.2 worked. This is in 4th shown. This forms between the noses 11.1 , 11.2 and the adjacent dividers 10.1 , 10.2 slot-shaped openings 17.1 , 17.2 , the contour of which by the punch lines 12.1 , 12.2 is limited. These folds can be performed in whole or in part at the same time or in succession.

As you fold further, slide accordingly 5 the dividers 10.1 , 10.2 with the sides facing each other along.

When the second connecting strip 7.1 , 7.2 on top of the bottom wall 2 meet are the dividers 10.1 , 10.2 arranged congruently next to each other.

In this position a nose covers it 12.1 the other nose 12.2 and reaches into the opening 17.2 in the divider 10.2 above the other nose 12.2 a. This is the first carrier 15.1 secured in the fully upright position. This is in 6th and 7th shown. The dividers 10.1 , 10.2 subdivide the first carrier 15.1 in two compartments 18.1 , 18.2 . Products that are separated from one another by the dividers can be placed in the compartments. This is advantageous for separating different types of product, for example.

The second carrier 15.2 of 8th to 11 differs from the first carrier 15.1 in that the first connecting strip 5.1 , 5.2 at the outer ends of the lower margins via sixth fold lines 19.1 , 19.2 with side retaining tabs 20.1 , 20.2 are connected. In the example are the side retaining tabs 20.1 , 20.2 rectangular.

When raising the second carrier 15.2 become the retaining tabs 20.1 , 20.2 each between the second connecting strips 7.1 , 7.2 and the bottom wall 2 fixed. This creates the first connecting strips 5.1 , 5.2 in contact with the inside of the side walls 3.1 , 3.3 and is prevented from being pulled off the side walls by the restoring forces in the box 3.1 , 3.3 stick out.

The third carrier 15.3 of 12th to 14th differs from the second carrier 15.2 in that the second connecting strip 7.1 , 7.2 have parallel first lateral edges. Furthermore, the second connecting strips are each over a third fold line 8.1 , 8.2 along the entire lower edge of the first connecting strip 5.1 , 5.2 connected to these. As a result, the first connecting strips when erecting 5.1 , 5.2 and the dividers 10.1 , 10.2 in the opposite direction to the first connecting strip 5.1 , 5.2 folded. This is especially true in 14th shown.
