Plate made of plastic material and method for producing a plate

Abstract

There is disclosed a plate ( 1 ) made of plastics material, in particular for young children, with a cavity ( 5 ) provided between a food surface ( 2 ) and a bottom area ( 3 ), and with a closeable opening ( 6 ) for filling the cavity ( 5 ) with a temperature control medium, wherein the plate ( 1 ) is blow-molded as one piece with the opening ( 6 ) whose axis is substantially parallel to the plane defined by the bottom area ( 3 ) and which is located in a lateral jacket face ( 4 ) joining the food surface ( 2 ) and the bottom area ( 3 ). Moreover, a method for producing such a plate ( 1 ) is described, wherein the plastics material for forming the plate ( 1 ) as one piece is blow-molded, and with the opening ( 6 ) provided in a lateral jacket face ( 4 ) which interconnects the food surface ( 2 ) and the bottom area ( 3 ) being produced at the same time.

1 . A plate ( 1 ) made of plastics material, in particular for young children, with a cavity ( 5 ) provided between a food surface ( 2 ) and a bottom area ( 3 ), and with a closeable opening ( 6 ) for filling the cavity ( 5 ) with a temperature control medium, characterized in that the plate ( 1 ) is blow-molded as one piece with the opening ( 6 ) whose axis is substantially parallel to the plane defined by the bottom area ( 3 ) and which is located in a lateral jacket face ( 4 ) joining the food surface ( 2 ) and the bottom area ( 3 ).  
     
     
         2 . A plate according to  claim 1 , characterized in that the plastics material in the bottom area ( 3 ) in comparison with the food surface ( 2 ) has a greater material thickness.  
     
     
         3 . A plate according to  claim 1  or  2 , characterized in that the food surface ( 2 ) is trough-shaped.  
     
     
         4 . A plate according to any one of  claims 1  to  3 , characterized in that the food surface ( 2 ) has a deepened partial region ( 7 ).  
     
     
         5 . A plate according to  claim 4 , characterized in that it has an indentation ( 9 ) in a lateral rim region ( 8 ) adjacent the deepened partial region ( 7 ).  
     
     
         6 . A plate according to any one of  claims 1  to  5 , characterized in that the opening ( 6 ) has a flange ( 12 ) with an external screw thread ( 11 ).  
     
     
         7 . A plate according to  claim 6 , characterized in that the opening ( 6 ) is closeable with a screw-type closure ( 10 ) having a self-sealing screw thread ( 11 ′).  
     
     
         8 . A plate according to any one of  claims 1  to  7 , characterized in that at least one handle ( 13 ) is provided separately from the cavity ( 5 ).  
     
     
         9 . A plate according to any one of  claims 1  to  8 , characterized in that at least one friction-increasing fixture ( 14 ) is provided on the bottom area ( 3 ).  
     
     
         10 . A method for producing a plate ( 1 ) of plastics material with a cavity ( 5 ) provided between a food surface ( 2 ) and a bottom area ( 3 ) and an opening ( 6 ) to fill the cavity ( 5 ) with a temperature control medium, characterized in that the plastics material for forming the plate ( 1 ) as one piece is blow-molded, with the opening ( 6 ) provided in a lateral jacket face ( 4 ) which interconnects the food surface ( 2 ) and the bottom area ( 3 ) being produced at the same time.  
     
     
         11 . A method according to  claim 10 , characterized in that the plastics material is extrusion-blow molded, injection-blow molded or stretch-blow molded.  
     
     
         12 . A method according to  claim 10  or  11 , characterized in that, prior to blow-molding, the plastics material is injected into an injection mold ( 15 ) with an injection channel ( 18 )-provided core part ( 17 ) so as to provide a preform which subsequently will be blow molded.  
     
     
         13 . A method according to  claim 12 , characterized in that the preform is formed with different wall thicknesses on two longitudinal sides.  
     
     
         14 . A method according to any one of  claims 10  to  13 , characterized in that a screw thread ( 11 ) is injection-molded in the plastics material.
