Abstract

In a storage device, particularly a piece of baggage or a purse, comprising at least one outer surface, wherein the at least one outer surface has arranged on it at least one three-dimensional protrusion extending from the outer surface, it is provided that the three-dimensional protrusion extending from the outer surface includes at least two mutually superimposed and interconnected layers.

First claim

The invention claimed is:

1. A storage device, particularly a piece of baggage, said storage device comprising:
at least one outer surface, wherein said at least one outer surface has arranged on it a plurality of three-dimensional protrusions extending from the outer surface, wherein
said three-dimensional protrusions extending from the outer surface comprises at least two mutually superimposed and interconnected layers, wherein the at least two layers are stacked and joined and have varying widths matching the shape of a corresponding pre-formed additional outer layer protrusion,
wherein said protrusions are rib-shaped and wherein the rib-shaped protrusions are arranged parallel next to each other at an equal distance running along-the outer surface,
wherein an additional outer layer is provided, the additional layer having at least one pre-formed additional outer layer protrusion, wherein the additional outer layer is affixed to the outer surface and the plurality of three-dimensional protrusions, and wherein the additional outer layer is arranged on the outer surface such that the plurality of three-dimensional protrusions are situated beneath the at least one pre-formed additional outer layer protrusion, and
wherein at least one space is provided between the layers of the protrusions and the additional outer layer.

2. The storage device according to claim 1 , wherein the protrusions extending from the outer surface are formed of at least two mutually superimposed and interconnected layers.

3. The storage device according to claim 1 , wherein the layers of the protrusions are printed.

4. The storage device according to claim 1 , wherein the protrusions comprise more than three mutually superimposed and interconnected layers which preferably are printed onto each other.

5. The storage device according to claim 1 , wherein the layers comprise a material which further comprises silicone and a ceramic paste.

6. The storage device according to claim 1 , wherein that layer of the protrusions which is adjacent to the outer surface is the lowermost layer, and that layer of the-protrusions which is most remote from the outer surface is the uppermost layer, the layers having different widths and the lowermost layer being wider than the uppermost layer.

7. The storage device according to claim 6 , wherein the widths of a plurality of mutually superimposed layers decrease, preferably continuously, from the lowermost layer to the uppermost layer.

8. The storage device according to claim 1 , wherein the layers are printed by offset printing or screen printing or by a 3D printing method.

9. The storage device according to claim 1 , wherein the plurality of protrusions arranged on the outer surface, are positioned on the outer surface with uniform distribution.

10. The storage device according to claim 1 , wherein the rib-shaped protrusions have a varying height in the longitudinal direction of the rib-shaped protrusions, the central area of the rib-shaped protrusions being higher than the edge areas of the rib-shaped protrusions.

11. The storage device according to claim 1 , wherein the individual layer thicknesses of the rib-shaped protrusions are varying in the longitudinal direction of the rib-shaped protrusions.

12. The storage device according to claim 1 , wherein said additional outer layer comprises at least one three-dimensional protrusion, applied by a thermoforming method, which is adapted to the three-dimensional protrusions arranged on the outer surface.

13. The storage device according to claim 1 , wherein the storage device is a piece of baggage comprising two major surfaces and four lateral surfaces, at least one of the major surfaces comprising rib-shaped protrusions, and the longitudinal direction of the rib-shaped protrusions extending parallel to the longitudinal direction of the major surfaces.
