Box-like container with an interpenetrating structure and process for the realization thereof

Abstract

A box-like hollow body, particularly a container of various shapes and size, comprising at least an inner hollow body 3 and an outer hollow body 2, interpenetrating with each other so as to create an integral structure with particular characteristics of mechanical resistance and ornamental, and provided with a continuous inner surface without gaps and an outer surface patterned according to zones or sections.

1 . A box-shaped hollow body, particularly a container of various shapes and size, such as a cup, jar, box, glass, jug and the like, characterized in that it comprises at least a first outer hollow body ( 2 ) and a second inner hollow body ( 3 ) interpenetrating with each other in such a way as to form an integral structure ( 1 ) and provided with a continuous inner surface without any gap and of an external surface patterned according to zones or sections constituted by portions ( 5 ,  5   a,    5   b ) of said second inner hollow body ( 3 ) emerging on the surface of said first outer hollow body ( 2 ), so as to form a substantially continuous, variously decorated outer surface.  
     
     
         2 . The box-like hollow body according to  claim 1 , characterized in that said first outer hollow body ( 2 ) is provided with apertures ( 4 ,  4   a ,  4   b ) such as holes, windows, cuttings and the like, variously located and having various shapes and size, and said second inner hollow body ( 3 ) is realized in the inside of said first outer body ( 2 ) and is provided with a continuous inner surface and an outer surface having raised portions ( 5 ,  5   a,    5   b ) with shape, size and thickness corresponding to the shape, size and thickness of said apertures ( 4 ,  4   a ,  4   b ), said raised portions being realized within said apertures and peripherally exactly and intimately matching the edge of said apertures.  
     
     
         3 . The box-like body hollow according to  claim 2 , characterized in that the edges ( 11 ,  12 ,  13 ) of said apertures are realized at an acute angle.  
     
     
         4 . The box-like hollow body according to  claim 1 , characterized in that it is realized from any material that is suitable to change its physical state from a flowing fluid during the working step to a solid in the finished product, such as plastic material and glass.  
     
     
         5 . A process for the fabrication of a box-like hollow body according to  claim 2 , characterized in that it comprises the following steps: 
 realization of said first outer hollow body ( 2 ) provided with said apertures ( 4 ,  4   a ,  4   b ) by casting or injection of a first material into a suitable mold having the selected shape,    casting or injection of a second material, compatible with said first material, into the inside of said first outer hollow body ( 2 ) placed in a suitable mold, so that said second material forms said second inner hollow body ( 3 ), filling said apertures ( 4 ,  4   a ,  4   b ) and realizing said continuous inner surface and forming an integral structure with said first hollow body.    
     
     
         6 . The box-like hollow body according to  claim 2 , characterized in that it comprises a first outer inner body ( 6 ), a second intermediate hollow body ( 7 ) and a third inner hollow body ( 8 ).
