Abstract

Disclosed is a decorative object including an upper glass, a lower glass, a recessed pattern formed in the lower glass and facing the upper glass, a liquid filling the recessed pattern, the refractive index of the liquid being equal to that of the lower glass or differing from that of the lower glass by at most 10%, and solid elements which can move in the liquid.

First claim

1 . A decorative object ( 1 ) comprising:
an upper glass ( 2 ), a lower glass ( 3 ), a recessed pattern ( 8 ) formed in the lower glass ( 3 ) and facing the upper glass ( 2 ), a liquid ( 10 ) filling the recessed pattern ( 8 ), the refractive index of the liquid ( 10 ) being equal to that of the lower glass ( 3 ) or differing from that of the lower glass ( 3 ) by at most 10%, and solid elements ( 11 ) which can move in the liquid ( 10 ).

2 . The decorative object as claimed in claim 1 , wherein the refractive index of the liquid ( 10 ) is equal to that of the lower glass ( 3 ) or differs from that of the lower glass ( 3 ) by at most 5%.

3 . The decorative object as claimed in claim 2 , wherein the refractive index of the liquid ( 10 ) is equal to that of the lower glass ( 3 ) or differs from that of the lower glass ( 3 ) by at most 2%.

4 . The decorative object as claimed in claim 1 , wherein the upper glass ( 2 ) and the lower glass ( 3 ) define between them an internal cavity ( 7 ) to which the recessed pattern ( 8 ) is open.

5 . The decorative object as claimed in claim 4 , wherein the liquid ( 10 ) fills the recessed pattern ( 8 ) and the internal cavity ( 7 ) completely.

6 . The decorative object as claimed in claim 4 , wherein the internal cavity ( 7 ) has a height (d) sufficient for the solid elements ( 11 ) to be able to completely exit the recessed pattern ( 8 ).

7 . The decorative object as claimed in claim 4 , wherein the internal cavity ( 7 ) has a height (d) not sufficient to allow the solid elements ( 11 ) to completely exit the recessed pattern ( 8 ).

8 . The decorative object as claimed in claim 1 , wherein the recessed pattern ( 8 ) comprises channels ( 9 ) which mutually communicate in the lower glass ( 3 ).

9 . The decorative object as claimed in claim 1 , wherein the solid elements ( 11 ) are balls.

10 . The decorative object as claimed in claim 1 , wherein the upper glass ( 2 ) is formed of a harder material than the material of the lower glass ( 3 ).

11 . The decorative object as claimed in claim 1 , wherein the upper glass ( 2 ) is formed of sapphire and the lower glass ( 3 ) is formed of borosilicate.

12 . The decorative object as claimed in claim 1 , wherein the lower glass ( 3 ) is formed of one of the following materials: borosilicate, crystalline glass, fused silica, crown glass, flint glass, quartz, transparent ceramic, sapphire, polymethyl methacrylate, polycarbonate, polyurethane.

13 . The decorative object as claimed in claim 1 , wherein the upper glass ( 2 ) is formed of one of the following materials: borosilicate, crystalline glass, fused silica, crown glass, flint glass, quartz, transparent ceramic, sapphire, polymethyl methacrylate, polycarbonate, polyurethane.

14 . The decorative object as claimed in claim 1 , consisting of a watch glass.

15 . The decorative object as claimed in claim 2 , wherein the upper glass ( 2 ) and the lower glass ( 3 ) define between them an internal cavity ( 7 ) to which the recessed pattern ( 8 ) is open.

16 . The decorative object as claimed in claim 3 , wherein the upper glass ( 2 ) and the lower glass ( 3 ) define between them an internal cavity ( 7 ) to which the recessed pattern ( 8 ) is open.

17 . The decorative object as claimed in claim 5 , wherein the internal cavity ( 7 ) has a height (d) sufficient for the solid elements ( 11 ) to be able to completely exit the recessed pattern ( 8 ).

18 . The decorative object as claimed in claim 5 , wherein the internal cavity ( 7 ) has a height (d) not sufficient to allow the solid elements ( 11 ) to completely exit the recessed pattern ( 8 ).

19 . The decorative object as claimed in claim 2 , wherein the recessed pattern ( 8 ) comprises channels ( 9 ) which mutually communicate in the lower glass ( 3 ).

20 . The decorative object as claimed in claim 3 , wherein the recessed pattern ( 8 ) comprises channels ( 9 ) which mutually communicate in the lower glass ( 3 ).
