• the tool 100 forms, around the cylindrical rod 104, a housing 110 shaped to receive the stopper 22a.
• the housing 110 is delimited on the outside by walls 112.
• the walls 112 can in particular make it possible to guide the relative movement of the stopper 22a with respect to the tool 100.
• two of the opposite walls 112 have, at their top, a recess 114 facilitating the removal of the hollow body 24 when the decorative piece 28 has been removed, as will be described later.
• a single wall 112 may have such a recess 114 or more than two walls 112.
• each wall 112 may have such a recess 114.
• the base 106 of the tool 100 also has a base 107, at the foot of the relief 102.
• the cross section of this base 107 is complementary to the housing 38 at the end 32a of the insert 32.
• the base 107 has a height h107, measured along the axis A4 of the tool, greater than or equal to the height of the housing 38 at the end 32a of the insert 32, measured along the direction of the axis A2.
• the tool 100 is for example made of plastic material.
• the tool is preferably in a material having a lower hardness than the material in which the cap 28 is made and/or soft to avoid damaging the cap 28 when the tool 100 is implemented.
• Tool 100 edges can also be rounded or chamfered
• the plug 22a is placed on the tool 100, so that the lugs 108 of the tool 100 are in contact with the crests 60 of the plate. support 52.
• the legs 108 of the tool 100 can then extend at least partially through the openings 35 in the insert 32.
• the positioning of the plug 22a on the tool 100 can be facilitated by the walls 112 delimiting the housing 110, the walls 112 making it possible to guide the plug 22a on the cylindrical rod 104.
• the housing 110 thus has, here, a cross section complementary to the cross section of the upper part of the cap 30, with symmetry by rotation around the axis A1. It will be noted here that positioning is also facilitated by the fact that plug 22a has symmetry by rotation around its axis A1, so that the four positions allowing the plug 22a to be received on tool 100, in particular in the housing 110, all lead to the same configuration. On the contrary, a rotational symmetry of the cap 28 appears less favorable to an easy positioning of the stopper 22a on the tool 100.
• plug 22a is pushed into housing 110 of tool 100.
• cap 28 is pushed, in the direction of axis A1 of plug 22a, towards of the tool 100.
• This thrust is guided by the walls 112 of the housing 110. This thrust results in a thrust of the tabs 108 on the crests 60 of the holes 58 of the support plate 52.
• the height h108 of the tabs 108 added to the height h60 of the ridges 60 can be at least greater than or equal to the height h40 of the beads 40.
• the height h108 of the tabs 108 added to the height h60 of the ridges 60 is preferably greater than or equal to the height h40 of the beads 40 added to the height h41 of the surface 41 connecting the upper end of the surfaces S40 to the second longitudinal end 32b of the insert 32.
• the height h108 of the legs 108 added to the height h60 of the ridges 60 where applicable is preferably greater than or equal to the distance, measured along the direction of the axis A2 of the insert, between the lower (or free) end of the surface S56 of the hooks 56 and the second end 32b of the insert 32.
• the thrust on the cap 28 is possible over a stroke c whose length, measured in the direction of the axis A4 of the tool 100, is at least greater than or equal to the height h40 of the beads 40
• the race c has a length greater than or equal to the height h40 of the beads 40 added to the height h41 of the surface 41 connecting the upper end of the surfaces S40 to the second longitudinal end 32b of the insert 32.
• the stroke c is preferably greater than or equal to the distance, measured along the direction of the axis A2 of the insert, between the lower (or free) end of the surface S56 of the hooks 56 and the second end 32b of insert 32.
• the race c is slightly less than or equal to the height h108 of the legs 108 to prevent the bottom of the insert 32 from being in abutment on the upper end of the cylindrical rod 104 before the insert is in abutment on the base 107.
• the piece of decoration 28 removed can then be kept, in particular for later reassembly on the stopper 22a of the bottle 12a or on another cover 22 adapted to another case 12, possibly.
• a new decorative piece 28 can then be placed in the stopper 22a, replacing the decorative piece 28 removed. This installation is carried out by elastic fitting, without requiring a priori the implementation of any tool.
• the packaging device for a cosmetic product is a perfume bottle provided with a pump.
• the bottle may however be devoid of such a pump.
• the fixing of a piece of decoration as it has just been described can also be carried out on a cap of a packaging device for applying a cosmetic product for the lips, in particular for a lipstick.
• the cap then presents such a decorative piece.
• the cap is attachable to a lipstick body, including a lipstick mechanism.
• the cap can be integral with an applicator element of the liquid cosmetic product.
• a rod connects the cap to the applicator element of the cosmetic product.
• the rod can be fixed or made from material with the insert in the cap.
• the free end of the cylindrical rod of the tool 100 advantageously has a hole allowing the rod and the applicator element to pass, when the plug is placed on the tool.
• the tool 100 does not cooperate with the elastic interlocking reliefs of the decorative piece, but pushes on the decorative piece.
• the elastic interlocking reliefs of the decorative piece are not accessible from inside the insert. These elastic interlocking reliefs are thus invisible to a user, which contributes to the aesthetic appearance of the stopper 22a.
• the elastic interlocking reliefs of the decorative piece are fixed to the insert, so as to be accessible from inside the insert.
• the elastic interlocking reliefs of the decorative piece can take the form of lugs passing through the openings in the insert and each be fixed to a rim of one of these openings. In this case, the lugs of the tool 100 can cooperate directly with these elastic fitting reliefs.
• the elastic interlocking reliefs of the decorative piece cooperate with complementary elastic interlocking reliefs formed by the cap.
