Storage tray for the detachable mounting of magnetically or magnetizablely equipped everyday objects

Abstract

The subject matter of the present invention relates to a tray for the detachable holding of magnetically or magnetizablely equipped consumer goods, wherein the holding of the consumer goods on the tray is based on a magnetic attraction force.

Description

[0001] The invention relates to a tray for the detachable holding of magnetically or magnetizablely equipped consumer objects, wherein the tray has a layer of a plastic material, wherein the plastic material has embedded metallic materials which have magnetic and / or magnetizable properties in order to effect a magnetic attraction with at least one magnetically or magnetizablely equipped consumer object.

[0002] Flexible mats that have a magnetic layer which provides slip protection for magnetically or magnetizablely equipped consumer goods placed on the mat are known, for example, from DE 10 2023 100 677.

[0003] Flexible substrates of this type, known from the prior art and featuring an inorganic metallic magnetic layer, have the disadvantage that the inorganic metallic magnetic layer can detach, at least partially, from the adjacent lower or upper layer of the substrate. A further disadvantage is that this magnetic layer can rust, at least at its outer edge. In particular, if a layer adjacent to the magnetic layer partially detaches, corrosion of the magnetic layer can be observed after only a short time. Attempts to encase this magnetic layer with a textile, for example, have not proven successful in practice because, due to the reduced adhesion of the magnetic layer, which consists of an inorganic iron material, detachment occurs after only a short time, resulting in at least partial corrosion of the inorganic magnetic layer.Another disadvantage is that the layers of the documents known from the state of the art consist of different materials, which makes the production of such documents more complex.

[0004] The object of the present invention is to provide a tray for the detachable holding of magnetically or magnetizablely equipped consumer goods, which does not exhibit corrosion, prevents the separation of the interconnected layers of the tray, and allows for simple manufacturing.

[0005] To solve the problem according to the invention, a tray for the detachable holding of magnetically or magnetizablely equipped consumer goods is provided, wherein the holding of the consumer goods on the tray is based on a magnetic attraction force, wherein the tray comprises at least a first layer, a second layer and a third layer, and wherein the tray is preferably bendable, characterized in that - the first layer is a film made of a plastic material, onto which the second layer is applied, - the second layer is formed from a plastic material, wherein the plastic material has embedded metallic materials which possess magnetic and / or magnetizable properties in order to produce a magnetic attraction with at least one magnetically or magnetizablely equipped consumer object, and - the third layer is formed from a plastic material with adhesive properties, which is self-adhesive and adheres to external surfaces in a repeatable and removable manner.

[0006] Embedding metallic materials in the second plastic layer, which possess magnetic and / or magnetizable properties, is advantageous because it prevents corrosion of the metallic materials.

[0007] A further advantage is that all three layers are formed from a single plastic material; preferably, each of the three layers contains polyurethane, which results in improved adhesion between the layers. This allows, for example, incompletely reacted isocyanate and polyol residues to form chemical bonds between the layers.

[0008] According to one embodiment, the tray has an additional fourth layer which, as a protective layer, adheres to the adhesively equipped third layer in a repeatable and removable manner, and protects it from contamination.
