Abstract

Carton (1) with a foldable insulated container (15) in its interior, the outer walls of the insulated container (15) abutting the inner walls of the folded cardboard (1) and the insulated container (15) being formed in one piece.

Description

The present invention relates to a carton with a foldable insulated container in its interior, in particular a folding carton.

The invention is based on cardboard boxes, in particular folding cardboard boxes, on the inside of which cardboard insulating material is fixed. The insulating material can be laminated on, glued on or fixed in any other way. Since these boxes have folds and / or gaps for folding, the insulation is partially interrupted. As a result of these interruptions, heat can get inside the carton and thus impair the insulating effect of the carton.

Proceeding from this, the object of the invention is to realize a carton with improved insulation.

This object is achieved by the combination of features of claim 1. The back-related claims contain partially advantageous and partially inventive developments of this invention.

The invention is based on the basic idea of arranging a further foldable and one-piece insulating container in the interior of a conventional carton. This insulating container is in one piece or in one piece and can be folded so that the insulating container folded into its end position is adapted to the interior of the box. It is important that the insulating container is self-contained in order to prevent thermal bridges from forming against the inner walls of the cardboard.

This insulating container consists of insulating material, for example an insulating film, insulating mats or the like. When the box is set up or folded up, the outer walls of the insulated container lie against the inner walls of the box. The walls, i.e. the side walls, the The size of the bottom and the lid of the insulated container are adapted to the walls of the folding carton so that the insulated container fits into the inside of the folding carton. It is advantageous if the insulating container is slightly larger than the inside of the box. The insulated container can then still be easily inserted into the interior of the box. However, the outer surfaces of the walls of the insulating container are slightly wavy, so that voids or free spaces in the interior of the cardboard box are filled or padded by the material of the insulating container. This slight oversize of the insulated container compared to the interior of the box can be realized, for example, by the fact that the surfaces of the walls of the insulated container and the surfaces of the adjacent walls of the cardboard are the same size and the wall thickness of the walls of the insulated container are selected so thick that they are, as it were, in the aforementioned Swell voids or open spaces.

In a further advantageous embodiment, a wall of the insulating container has a larger area than the wall of the carton assigned to it. In this way, the outer surfaces of the walls of the insulating container in turn wave outwards and can thus penetrate into and fill in cavities or free spaces in the cardboard interior of the folded cardboard.

If the term "wall" is used in this text, it can alternatively be the front wall, side wall, rear wall, the bottom or the lid of the carton and / or the insulating container. The term "wall" is, as it were, a generic term for a wall element, regardless of whether this concerns the floor, the lid or any type of wall of the folding carton or the insulating container.

The present invention is particularly suitable for folding cartons. However, the effect of the insulated container can also be achieved with differently constructed cartons. For example, the box can also be put together. The invention is therefore suitable for all types of cartons.

In a further advantageous embodiment, the surface of the insulating container base is larger than that of the cardboard base. This causes the corrugation of the insulating material of the insulating container already mentioned. In this way, the edge areas between the side walls of the insulating container form upholstery-like beads or upholstery. In the manner of sealing rings or sealing rubbers, these bead-like edge areas of the insulating container fill the corner areas formed by the side walls of a folding carton. Since creases or weaknesses are formed in the corner areas for folding the side walls of a folding box, these beads improve the sealing effect of the insulating container, in particular in corresponding edge areas of a folding box.

In a further advantageous embodiment, the outer walls of the insulating container are fixed to the inner walls of the cardboard, for example glued on with the aid of an adhesive film. In this way it is possible, for example, to adapt the foldable insulated container to the unfolded blank of a folding box and to set up the folding box consisting of a folding box and a foldable insulated container in a single folding operation. The customer can do this himself. It is also advantageous to partially or completely unfold the folding box with the insulated container adapted thereon before or after transport, in order to be able to store the folding box flat or to be able to transport it flat and thus saving space.

To further improve the sealing effect, it is proposed to connect the pivotable tabs on the upper edges or the lower edges of the side walls of the insulating container to the respectively adjacent insulating container cover or insulating container bottom. If the insulated container is unfolded into its transport position, overlaps form between the tabs and the insulated container lid or insulated container bottom, thus doubling up the sealing material in this area. This measure also leads to an improvement in the insulating effect in the sensitive edge areas or corner areas.

These overlaps also counteract a decrease in the insulating capacity of the insulating container if the carton is damaged in edge areas, for example.

a folded blank of a folding box and

Fig. 2

the matching cut of the foldable insulated container.

The in Fig. 1 The carton 1 shown in the unfolded state is a folding carton and consists of a carton front wall 2, two carton side walls 3, a carton rear wall 4, a carton bottom 5 and a carton lid 6 pivotable reinforcement tabs 8 are arranged, which in turn carry a plug-in tab 9 on each edge. On the underside of the cardboard front wall 2, a stabilizing tab 10 is pivotally mounted. The stabilizing tab 10 has a pocket 11 on the side. Likewise, the cardboard bottom 5 has a pocket 11. In each pocket 11 one of the tabs 9 is inserted when the carton 1 is unfolded. Finally, a closing tongue 12 is cut out of the upper edge of the cardboard front wall 2. At the front edge of the cardboard cover 6, a receiving slot 13 complementary to the closing tongue 12 is provided in order to be able to close the cardboard cover 6 in the region of the cardboard front wall 2. In the area of the receiving slot 13, an additional locking tab 14 is also pivotally mounted.

Analogous to the carton 1 described above, the in Fig. 2 Insulated container 15 shown a container front wall 16, two container side walls 17, a container rear wall 18, a container bottom 19 and a container lid 20. Additional insulating tabs 21 are each pivotably mounted on the upper edges and the lower edges of the front wall 16 of the container and the side walls 17 of the container. The insulating tabs 21 are connected with overlaps 22 to the adjacent container lid 20 or container bottom 21.

In Fig. 1 finally glue points 23 can be seen. The adhesive points 23 are arranged on the inner sides of the carton bottom 5, the carton rear wall 4, the carton side walls 3 and the carton front wall 2. Furthermore, the reinforcing tabs 8 and the stabilizing tab 10 in the exemplary embodiment also carry glue points 23 Fig. 2 shown blank of the insulating container 15 fixed on the cardboard 1 before unfolding.

With the help of dimension arrows, the intrinsic length 24 and the intrinsic width 25 of the carton front wall 2, the carton side walls 3, the carton rear wall 4, the carton bottom 5 and the carton lid 6 of the carton 1 on the one hand and the container front wall 16, the container side walls 17, the container rear wall 18, of the Container bottom 19 and the container lid 20 of the insulating container 15 indicated on the other hand. In the exemplary embodiment, the intrinsic length 24 and the intrinsic width 25 of the carton front wall 2, the carton side walls 3, the carton rear wall 4 and the carton lid 6 are each greater than or equal to the intrinsic length 24 or the intrinsic width 25 of the corresponding container front wall 16, container side walls 17, container rear wall 18 and container lid 20 In the case of the container bottom 19, its own width 25 is larger than the own width 25 of the corresponding carton bottom 5. In this way, the container bottom 19 has a larger area than the carton bottom 5.

The carton 1 has fold edges 26 between its pivotable elements. After the folding box 1 and the insulating container 15 connected to the folding box 1 via the gluing points 23 have been set up, bulges or the like form on the insulating container 15 as a result of the excess of the insulating container 15 compared to the interior of the folding box. These beads protrude into the folded edges 26 and fill the folded edges 26 on the cardboard 1 set up in an insulating manner. The same applies to the overlaps 22 already mentioned, which protrude into free spaces 27 on the carton 1.
