         3 . The object according to  claim 2 , wherein the passage opening, arranged to provide a passage for the collar of the bottle, has a passage dimension greater than a passage dimension (D 2 , D′ 2 ) of the U or C of the upper collar of the shell arranged to elastically interlock on at least part of the collar of the bottle. 
     
     
         4 . The object according to  claim 3 , wherein:
 the passage dimension of the shell passage opening arranged to provide a passage for the collar of the bottle is strictly greater than a dimension of the collar of the bottle, and/or   the passage dimension of the U or C of the upper collar of the shell, arranged to elastically interlock on at least part of the collar of the bottle, is strictly smaller than the dimension of the bottle collar.   
     
     
         5 . The object according to  claim 2 , wherein the shell comprises an introduction opening arranged in the side wall and arranged to allow a user to introduce the bottle into the shell. 
     
     
         6 . The object according to  claim 1 , wherein the collar of the bottle comprises a flange. 
     
     
         7 . The object according to  claim 1 , wherein the collar of the bottle comprises a protuberance engaged in the opening of the U or C of the upper collar of the shell, preferably under a flange of the collar of the bottle. 
     
     
         8 . The object according to  claim 7 , wherein: the opening of the U or C of the upper collar of the shell has a first angular dimension relative to an axial direction of the object,
 the protuberance has a second angular dimension relative to the axial direction of the object, smaller than the first angular dimension.   
     
     
         9 . The object according to  claim 1 , wherein the bottle, seen from outside, has a concave, for example hemispherical, bottom and wherein the shell has a bottom defining at least one planar support portion for laying the object along a vertical position. 
     
     
         10 . The object according to  claim 9 , wherein the shell has an external diameter, and wherein the bottom of the shell comprises at least one planar crown, or support portions distributed along a planar crown, the planar crown having a diameter greater than or equal to 50% of the external diameter. 
     
     
         11 . The object according to  claim 1 , characterized in that the shell comprises at least one gripping handle, forming for example a handle. 
     
     
         12 . The object according to  claim 1 , wherein the bottle has a preferably cylindrical body with a thickness comprised:
 in a range from 30 μm to 150 μm,   and for example in a range from 30 μm to 50 μm or from 50 μm to 70 μm or from 70 μm to 100 μm, or from 100 μm to 125 μm or from 125 μm to 150 μm,   and preferably in a range from 100 μm to 125 μm.   
     
     
         13 . The object according to  claim 12 , wherein the bottle has a bottom with a thickness equal by ±20% to the thickness of the body of the bottle, with the exception of a central portion of the bottom comprised in a diameter:
 less than or equal to 50% of the diameter of the cylindrical part of the body, 
 preferably less than or equal to 35% of the diameter of the cylindrical part of the body, 
 more preferably less than or equal to 20% of the diameter of the cylindrical part of the body. 
 
     
     
         14 . The object according to  claim 1 , wherein the collar and/or the flange of the bottle has a thickness greater than 150 μm, preferably greater than 200 μm, and more preferably greater than 250 μm. 
     
     
         15 . The object according to  claim 1 , wherein the bottle is formed from polyethylene terephthalate (PET).
