Abstract

A cardboard box has a fold-out hanger arranged in a cut-out of the cardboard box, wherein at least a hanger portion of the cardboard box is assembled from two layers of cardboard, the hanger portion having a first hanger portion formed from a first cardboard layer and a second hanger portion formed from a second cardboard layer, wherein a first hanger section of the first hanger portion forms a front side of the hanger, a second hanger section of the second hanger portion forms a backside of the hanger and the second hanger section is smaller in lateral extension than the first hanger section.

First claim

What is claimed is:

1. A cardboard box having a fold-out hanger arranged in a cut-out of the cardboard box, wherein the cardboard box is made of a blank comprising a hanger portion having a first hanger portion and a second hanger portion, the first hanger portion having a first cutout in which a first hanger section is arranged and the second hanger portion having a second cutout in which a second hanger section is arranged, wherein the first hanger section is integrally connected with a first frame section of the first hanger portion along a perforated or otherwise weakened separation line in a top area of the hanger and the second hanger section is separated from a second frame section of the second hanger portion by a separation gap in a top area of the hanger.

2. The cardboard box in accordance with claim 1 , wherein the second hanger section does not extend until the separation line between the first hanger section and the first frame section.

3. The cardboard box in accordance with claim 1 , wherein the second hanger section is integrally connected with the second frame section along a partially pre-cut or otherwise weakened folding line in the bottom area of the hanger.

4. The cardboard box in accordance with claim 1 , wherein the second hanger section is smaller in size than the first hanger section in side areas of the hanger.

5. The cardboard box in accordance with claim 1 , wherein the first hanger portion and the second hanger portion are glued together.

6. The cardboard box in accordance with claim 1 , wherein each of the hanger sections comprises a punching-out.

7. A blank for making a cardboard box, the blank comprising a hanger portion having a first hanger portion and a second hanger portion, the first hanger portion having a first cutout in which a first hanger section is arranged and the second hanger portion having a second cutout in which a second hanger section is arranged, wherein the first hanger section is integrally connected with a first frame section of the first hanger portion along a perforated or otherwise weakened separation line in a top area of the hanger and the second hanger section is separated from a second frame section of the second hanger portion by a separation gap in a top area of the hanger.

8. The blank in accordance with claim 7 , wherein the first hanger portion and the second hanger portion are hinged together along a folding line such that when folded together the first hanger section overlays the second hanger section such that the first cutout and the second cutout become aligned with each other.

9. The blank in accordance with claim 7 , wherein the first hanger section and the second hanger section each comprise identical punching-out portions such that when the first hanger portion and the second hanger portion are folded together, the punching-out portions become aligned with each other.

10. A method of making a cardboard box comprising the steps of:
providing a layer of cardboard comprising a blank comprising a hanger portion having a first hanger portion and a second hanger portion, the first hanger portion having a first cutout in which a first hanger section is arranged and the second hanger portion having a second cutout in which a second hanger section is arranged, wherein the first hanger section is integrally connected with a first frame section of the first hanger portion along a perforated or otherwise weakened separation line in a top area of the hanger and the second hanger section is separated from a second frame section of the second hanger portion by a separation gap in a top area of the hanger;
slitting and scoring the layer of cardboard such that the blank results having the hanger portion comprising the first hanger portion having the first hanger section being arranged in the first cutout and the second hanger portion having the second hanger section being arranged in the second cutout, where the second hanger section is smaller in its lateral extension than the first hanger section; and
folding the blank such that the first hanger section overlays the second hanger section such that the first cutout and the second cutout are aligned with each other.

11. The method in accordance with claim 10 , further comprising the step of gluing together the first hanger portion and the second hanger portion.
