• a third gap 40 is formed between the lid and the pot, giving it a very particular appearance and which is obtained in a simple manner, without revealing traces of joint planes which would necessarily exist in the case of an embodiment by molding using a jaw mold.
• the shells 12 and 20 can be produced by molding of plastic, metal or metal alloy, glass, or any other material suitable for the product that the pot is intended to contain and the rings 25 and 31 can be made of the same materials or in different materials.

• the shells 12 and 20 intended to enter into the constitution of the body of the container and of the cover are very close to those of the shells 12 and 20 of the previous embodiment. With said shells, however, no longer cooperate rings or rings.
• cylindrical outer surface but three linings 45 for the body and a lining 46 for the cover whose cross section through a plane passing through the vertical axis 47 of symmetry of the pot is trapezoidal and of increasing sec ⁇ tions, so that this results in a different aspect of the container device, which is somewhat frustoconical. with interstices 30, 30a, 30b ... as shown on the right-hand side of FIG. 3.

• Duplateau 60 depends on a lip 65 which, in the condition of closure of the jar, cooperates with a cover 66 which rests on the periphery edge 67 of the shell 50.
• the linings are constituted by rings 70_,, 70 2 , 70 3 each of which is provided on its internal face 71 with gadroons 72, regularly distributed from the angular point of view and which serve to fix said rings relative to shell 50.
• each ring 70 by a plane passing through the axis of revolution of the pot is of generally rectangular shape, with diagonally opposite angles cut one along a rabbet 74 and the other along a shoulder 75 from which depend legs 76, regularly distributed over the edge of the ring and each of which has a cutaway 77 at its free end.
• the rings 70 are placed on the shell 50 by first threading the ring 70 3 until the flange 55 comes to be housed in the rebate 74 and that , by cooperation of the gadroons 72 with the lateral surface 52 of the shell, said ring is immobilized relative to the co ⁇ keel.

• the cap can be fixed by ultrasonic welding.
• the cover 11 For the manufacture of the cover 11, it is a ring 70 identical to those described above which is used with, however, an inverted presentation relative to the shell 51 since the legs 76 are housed in the groove 62 of said shell while the rib 64 is partly housed in the rabbet 74 for holding the ring relative to the shell against a longitudinal movement, the immobilization in rotation of the ring on the shell being here also ensured by the gadroons 72 of the ring.
• this immobilization in rotation can be achieved by providing a rib 85 projecting from the external face 86 of the side wall of the shell, FIG. 8, and a groove 87 of conjugate shape on the ring 70.
• the gadrooned structure makes it possible to manufacture with the same mold rings of different materials, or rings of the same material but of different colors, the possible variations of the withdrawal of a material or a color to a other not constituting obstacles to the satisfactory assembly of the rings on the shells.
• the invention is not limited to jar devices as shown in FIGS. 1 to 6.
• the method and the device according to the invention can be used for the manufacture of multiple packages of perfumery or cosmetics, such as bottles, or tubes of lipstick R, for example, by mounting on a shell 92 a plurality of rings 93 joined together and to said shell by one or the other of the means described above, figure 11.
