Abstract

The invention relates to an injection molded part with a basic body injection-molded from plastic, on the surface of which a decoration is two-dimensionally applied and is covered by an encapsulation of plastic by a second injection-molding operation. The basic body consists of a transparent plastic and the decoration is applied with its visible side to the surface of the basic body.

Claims

exact text as granted — not AI-modified
1 . An injection molded part, with a body injection-molded from a first plastic, on a surface of which a decoration having a decorative first side and a back side is two-dimensionally applied and is covered by an encapsulation of a second plastic by a second injection-molding operation, characterized in that wherein the body of comprises a transparent and/or opaque and/or translucent plastic and the decoration is applied with its decorative side to the surface of the body.  
   
   
       2 . (canceled)  
   
   
       3 . The injection molded part as claimed in  claim 1 , wherein the encapsulation covers one or more decoration-free regions of the basic body with the first and second plastics bonded to each other.  
   
   
       4 . (canceled)  
   
   
       5 . The injection molded part as claimed in  claim 3 , wherein the first and second plastics have different degrees of hardness.  
   
   
       6 . The injection molded part as claimed in  claim 3 , wherein the decoration-free regions are arranged in an edge region adjacent the decoration.  
   
   
       7 . The injection molded part as claimed in  claim 6 , wherein the encapsulation extends over the body beyond the edge region adjacent the decoration.  
   
   
       8 . The injection molded part as claimed in  claim 3 , wherein the decoration-free regions are arranged in an interior region of the decoration.  
   
   
       9 . The injection molded part as claimed in  claim 3 , wherein the body has, in one or more of the decoration-free regions, recesses which are open toward its surface and are filled by the second plastic of the encapsulation.  
   
   
       10 . (canceled)  
   
   
       11 . The injection molded part as claimed in  claim 1 , wherein the surface of the body bearing the decoration is substantially planar.  
   
   
       12 . The injection molded part as claimed in claims  1 , wherein the surface of the body bearing the decoration is convexly curved.  
   
   
       13 . The injection molded part as claimed in  claim 1 , wherein an edge region of the surface of the body surrounding the decoration is formed at a lower-lying level than the surface covered by the decoration.  
   
   
       14 . The injection molded part as claimed in  claim 13 , wherein the edge region of the surface of the body surrounding the decoration is formed in a convexly rounded manner.  
   
   
       15 . The injection molded part as claimed in  claim 14 , wherein the convex rounding extends into an outer edge region of the surface of the body bearing the decoration.  
   
   
       16 . The injection molded part as claimed in  claim 1 , wherein the decoration is applied by means of a hot transfer film, or by means of a metallized film.  
   
   
       17 . The injection molded part as claimed in  claim 1 , wherein the decoration is applied to the surface of the body by printing.  
   
   
       18 . The injection molded part as claimed in  claim 1 , wherein a further decoration is applied to the encapsulation and is covered by a further encapsulation, which covers one or more regions of the first encapsulation that are free from the further decoration with the second encapsulation bonded to the first encapsulation.  
   
   
       19 . The injection molded part of  claim 1 , wherein the part is a toothbrush body.  
   
   
       20 . A method of injection molding a part, the method comprising: 
 injection molding a body from a first plastic;    applying at least a two-dimensional decoration to a surface of the body, the decoration having a decorative front side and a back side; and then    covering the applied decoration with an encapsulating layer of a second plastic, the second plastic injection molded over the decoration;    wherein the body comprises a transparent or translucent plastic, and the decoration is applied with its decorative front side facing the body, such that the decorative front side is visible through the body.    
   
   
       21 . The method as claimed in  claim 20 , wherein the encapsulating layer covers a decoration-free region of the body and the first plastic bonds with the second plastic in the decoration-free region.  
   
   
       22 . The method as claimed in  claim 21 , wherein the first and second plastics have different degrees of hardness.  
   
   
       23 . The method as claimed in  claim 21 , wherein the decoration-free region is an edge region adjacent the decoration.  
   
   
       24 . The method as claimed in  claim 23 , wherein the encapsulating layer extends over the body beyond the edge region.  
   
   
       25 . The method as claimed in  claim 21 , wherein the decoration-free region is arranged in an interior region defined within the decoration.  
   
   
       26 . The method as claimed in  claim 21 , wherein the body has a recess in the decoration-free region which are open toward its surface and are filled by the plastic of the encapsulating layer, the recess defining an alphanumeric character or symbol.  
   
   
       27 . The method as claimed in  claim 20 , wherein an edge region of the surface surrounding the decoration is formed at a lower-lying level than a covered region of the surface under the decoration.  
   
   
       28 . The method as claimed in  claim 20 , further comprising: 
 applying a further decoration applied to the encapsulating layer; and    injection molding a second encapsulating layer covering at least a region of the first encapsulating layer that is free from the further decoration;    wherein the second encapsulating layer bonds with the first encapsulating layer.    
   
   
       29 . The method of  claim 20 , wherein the part is a toothbrush body.
