Definitions

  • the invention relates to a refill for a cosmetic stick made from a spreadable cosmetic mass intended for consumption and to a method for producing the cosmetic stick.
  • the refill is filled into a sleeve, from which it is pushed out according to its consumption with a stamp, which increasingly penetrates the sleeve by rotating a grip part of the cosmetic pencil relative to the sleeve and the rear Pushes the end of the mine in front of you.
  • the lead adheres to the inside of the sleeve to a greater or lesser extent, with higher adhesive forces occurring in particular with sleeves made of plastic.
  • the stamp which is provided with an external thread and whose outside diameter is somewhat smaller than the inside diameter of the sleeve, penetrates into the soft lead material, while the lead adheres to the inside wall of the sleeve.
  • the present invention has for its object to avoid such destruction of the mine, even if the aforementioned adhesive forces occur undiminished.
  • this proposal means a relatively small additional effort, which consists in filling wax to form the wax plug in a filling station. This can be done within the same filling station through a second supply line for the wax or in two successive filling stations, the cosmetic mass and then the wax being expediently filled in because of the difference in density.
  • the wax hardened into a plug acts like a piston made of solid material.
  • the stopper lies sealingly against the inner wall of the sleeve and can be easily pushed forward by the stamp screwing increasingly into the sleeve in the sleeve, displacement of the spreadable cosmetic composition behind the stopper being impossible.
  • cosmetic mass and wax plugs are used instead of being poured into a mold directly into the sleeve of the cosmetic pencil. In this way, there is no need to separately move the lead provided with the plug from the casting mold into the sleeve.
  • the method according to the invention or the use of the refill according to the invention enables in particular the use of cosmetic pencils with a simple structure, i.e. while avoiding another component, which has the function of the extension piston.
  • the stamp has at its front end such a component in the form of a cup which is open towards the front and into which the associated end of a refill made of soft cosmetic material is inserted.
  • This solution is disadvantageous both because of the larger number of its components and because of its complex assembly.
  • any wax that is solid at ambient temperature in particular hard wax, for example simple candle wax (paraffin), can be used as the material for the wax plug.
  • the wax is in the sleeve or in poured a special mold in the liquefied state, expediently directly on the liquid level of the cosmetic mass already filled. Since this has a higher density than the wax, there is no mixing of the two materials, so that the entire volume of the cosmetic composition is available for cosmetic use.
  • FIG. 1 shows a cosmetic stick 1 with a handle part 2, a stamp 3 accommodated therein, and a sleeve 4 which is rotatably but axially immovably received in the handle part.
  • the lead 5 is filled into the sleeve 4. It comprises the actual cosmetic composition 6 and in its rearward extension a plug 7 made of hard wax.
  • the end face 8 of the stamp 3 presses against the stopper 7, which pushes the soft cosmetic mass 6 in front of it like a piston, the further the stamp 3 screws into the interior of the sleeve 4.
  • the stamp 3 is arranged in the interior of the handle part 2 in a rotationally fixed but axially displaceable manner.
  • station I the soft cosmetic mass is filled into the sleeve 4.
  • station I the soft cosmetic mass is filled into the sleeve 4.
  • the outer end of the sleeve 4 is inserted into a corresponding bore in a casting mold 10.
  • a cannula 11 loaded with cosmetic mass which is shown in the retracted position, penetrates from this position through the bore of the internal thread 9 into the sleeve 4 up to a lower position shown in dash-dotted lines and, during its retraction movement upwards, takes care of the filling of the cosmetic mass 6.
  • the plug of hard wax is filled in, whereby the heated wax is applied in liquid form through a further cannula 12 to the liquid level of the cosmetic composition 6 in the lower filling position of the cannula 12, shown in dash-dot lines. Due to the lower density of wax, it does not mix with the cosmetic composition 6.
  • the sleeve 4 is mounted inside the handle part 2, as shown in FIG. 1; an annular bead 13 projecting inside the handle part 2 forms a snap connection with a corresponding annular groove 14 of the sleeve 4.

Abstract

Une mine (5) de crayon cosmétique (1) ou similiare composée d'une masse de produit cosmétique enductible qui remplit un manchon tubulaire (4) du crayon cosmétique (1) et qui peut en être expulsée graduellement par un plongeur (3) à des fins d'utilisation, est pourvue à son extrémité postérieure d'un bouchon en cire (7) qui sert de piston d'expulsion et dont la section transversale correspond à celle de la mine (5).

Claims (5)

  1. Mine (5) pour crayon cosmétique ou analogue, constituée par une masse cosmétique (6) apte à être appliquée et qui est introduite dans une douille tubulaire (4) du crayon cosmétique (1), pour en être ressortie progressivement, à partir de là, à l'aide d'un poussoir (3) en vue de son utilisation, caractérisée en ce que la mine (5) est prolongée, au niveau de son extrémité arrière, par un bouchon (7) en cire ou en un matériau analogue se solidifie lors de son refroidissement à la température ambiante, et qu'il constitue un piston d'éjection, dont la section transversale correspond à celle de la mine (5).
  2. Procédé pour fabriquer une mine selon la revendication 1, caractérisé en ce qu'on introduit successivement à l'état liquide, dans un moule de coulée, d'une part la masse cosmétique (6) et d'autre part la cire formant le bouchon (7).
  3. Procédé selon la revendication 2, caractérisé en ce que pour le remplissage, on raccorde le moule de coulée à deux postes séparés de remplissage, l'un pour la masse cosmétique (5) et l'autre pour la cire.
