Decorated injection moulded product, and a method for producing the same

Abstract

A method for producing an injected moulded product includes producing a first injection moulded layer having an external and an internal surface, of which the external surface is directed towards a front face of the injection moulded product. A foil is attached to the first injection moulded layer. The foil has first and second sides, and there is at least one pattern on the foil. The foil is placed against the internal surface of the first injection moulded layer. The injection moulded product may include a second injection moulded layer so that the first injection moulded layer, the foil and said second injection moulded layer constitute, in this order, an integral layered structure. The first side of the foil is next to the internal surface of the first injection moulded layer and said second injection moulded layer is next to the second side of the foil.

1 . An injection moulded product, comprising: 
 a first injection moulded layer having an external surface and an internal surface, of which the external surface is directed towards a front face of the injection moulded product;    a foil attached to the first injection moulded layer, the foil having a first side and a second side; and    at least one pattern on the foil,    wherein the foil is attached to the internal surface of the first injection moulded layer.    
   
   
       2 . An injection moulded product according to  claim 1 , wherein the first side of the foil is next to the internal surface of the first injection moulded layer, the pattern is on the first side of the foil, and the first injection moulded layer is transparent or translucent to visible light at a location that is next to the pattern.  
   
   
       3 . An injection moulded product according to  claim 2 , wherein the whole first injection moulded layer is transparent or translucent to visible light.  
   
   
       4 . An injection moulded product according to  claim 3 , wherein the first injection moulded layer comprises visual effect particles embedded in the injection moulded substance.  
   
   
       5 . An injection moulded product according to  claim 3 , wherein the first injection moulded layer comprises a colouring agent mixed into the injection moulded substance.  
   
   
       6 . An injection moulded product according to  claim 1 , wherein the first side of the foil is next to the internal surface of the first injection moulded layer, the pattern is on the second side of the foil, and the first injection moulded layer and the foil are transparent or translucent to visible light at a location that is next to the pattern.  
   
   
       7 . An injection moulded product according to  claim 1 , wherein the foil consists of a single base foil, on the surface of which the pattern is located.  
   
   
       8 . An injection moulded product according to  claim 1 , wherein the foil consists of a base foil having an unpatterned side, which is next to said first injection moulded layer, and a number of other foils.  
   
   
       9 . An injection moulded product according to  claim 1 , wherein: 
 the injection moulded product comprises a second injection moulded layer; and    the first injection moulded layer, the foil and said second injection moulded layer constitute, in this order, an integral layered structure where the first side of the foil is next to the internal surface of the first injection moulded layer and said second injection moulded layer is next to the second side of the foil.    
   
   
       10 . An injection moulded product according to  claim 9 , wherein the whole second injection moulded layer is transparent or translucent to visible light.  
   
   
       11 . An injection moulded product according to  claim 9 , wherein the foil consists of a base foil having an unpatterned side, which in said integrated layered structure is next to said second injection moulded layer, and a number of other foils.  
   
   
       12 . An injection moulded product according to  claim 9 , wherein the foil consists of a base foil having an unpatterned side, which in said integrated layered structure is next to said second injection moulded layer, a number of other foils laminated with said base foil into a laminated foil structure, and patterning on at least some surfaces of said other foils.  
   
   
       13 . An injection moulded product according to  claim 9 , comprising another foil and another injection moulded layer, which are together in this order next to said second injection moulded layer.  
   
   
       14 . An injection moulded product according to  claim 1 , wherein: 
 it comprises a secret security code which is a pattern on the foil;    said secret security code is within said integrated layered structure surrounded by layers that are opaque to visible light but translucent to certain other electromagnetic radiation; and    said secret security code is essentially less translucent to said other electromagnetic radiation than the layers surrounding it.    
   
   
       15 . An injection moulded product according to  claim 1 , characterised in that it is a cover for a mobile telecommunications device.
