Abstract
The present invention relates to a method for replicating a surface relief. In particular, the present invention relates to a method for replicating a surface relief in a non-metallic layer being held by a metal substrate. Furthermore, the present invention relates to an article for holding a surface relief. The article will typically form an integral part of a metal container, such as a food container.
Claims35
A method for replicating a surface relief, said method comprising the steps of
- providing a first layer of a non-metallic material, and
- pressing into the first layer of non-metallic material an object comprising a surface so as to change surface properties of the first layer of non-metallic material in order to replicate at least one surface relief, said at least one surface relief forming part of the surface of the object.
A method according to any of the preceding claims further comprising the step of providing a second layer, said second layer being substantially transparent and covering at least part of the first layer of non-metallic material.
A method according to any of the preceding claims, wherein the at least one surface relief replicated in the first layer of non-metallic material comprises a diffracting optical element.
A method according to any of the preceding claims, wherein the thickness of the first layer of non-metallic material is within the range 1-50 μm, such as within the range 2-25 μm, such as within the range 2-20 μm, such as within the range 5-15 μm, such as within the range 5-10 μm.
A method according to any of the preceding claims, wherein replication of the at least one surface relief is performed as a part of a rolling process.
A method for replicating a surface relief, said method comprising the steps of
- providing a first layer of a non-metallic material, said first layer of non-metallic material being held by a metal substrate,
- pressing into the first layer of non-metallic material an object comprising a surface so as to change surface properties of the first layer of non-metallic material in order to replicate at least one surface relief, said at least one surface relief forming part of the surface of the object, and
- providing a metal layer onto at least part of the at least one replicated surface relief, said metal layer being substantially conform with the at least one replicated surface relief.
An article for holding a surface relief, said article comprising
- a metal substrate, and
- a first layer of non-metallic material being held by the substrate, said first layer of non-metallic material being adapted to hold at least one surface relief.
An article for holding a surface relief, said article comprising
- a metal substrate,
- a first layer of non-metallic material being held by the substrate, said first layer of non-metallic material being adapted to hold at least one surface relief, and
- a metal layer covering at least part of the first layer of non-metallic material and being substantially conform with the at least one replicated surface relief being held by the first layer of non-metallic material.
