Definitions

  • the present invention refers to a mechanical filling process of a container for cosmetic products, in particular of a pencil.
  • the cosmetic products are placed into suitable containers having cylindrical or similar shape and into flat containers, inside corresponding cups or inserts.
  • the product is put inside the insert and then it is flattened so as to fill the insert and finally said product is compacted to eliminate the presence of air bubbles and to be precisely positioned inside said insert.
  • the products are realised in the form of a stick or of a more or less thin cylindrical element.
  • the pastel or the lead are cast into a die and are then inserted in the corresponding cup of the container.
  • the document EP-A-723 880 describes a manufacturing process for cosmetic pencils which is related to the preamble of claim 1.
  • said process provides that a filling cosmetic product is fed within a chanter and, during a first phase, the product is doughy, hot and under pressure. Then, the product is cooled.
  • the EP-A-686 468 document describes a molding process for lipsticks, while the US-A-5 316 712 document discloses a manufacturing process of a solid cosmetic composition.
  • the general purpose of the present invention is to overcome the technical problems associated with the known technique in a very simple economic and particularly functional manner.
  • Another purpose is to completely eliminate the presence of air within the product, and to make said product more stable and less fragile.
  • an apparatus 10 comprises a heating tank, which is shown in 11 and which comprises a sealed cell 12 with a controlled nitrogen atmosphere.
  • the material placed in this tank 11 into the sealed cell 12 is fed through a gear pump 13 to an insulated feeding duct 14 under a defined pressure P1.
  • the duct 14 is connected to an injection head 15 provided with an obturator 16, for instance of the electromagnetic type.
  • a die 17 is placed right below said injection head 15 wherein a pastel or stick 28 for a pencil container, which will be herein described.
  • the die 17, better shown in figure 2 is formed by an outer structure or mold 18 wherein a mobile ejector 21 with an enlarged head 22 is placed inside a hole housing 19 and 20, having various shapes.
  • the mobile ejector 21 has the same diameter of the cosmetic product to be realised and slides along a first portion 20 of the hole housing, which defines a variable volume chamber.
  • the chamber 20 has a variable volume which goes from zero or almost zero to the final value since said chamber is provided with a mobile wall subjected to a predefined counter-pressure, which is applied on the upper end 21a of the mobile ejector 21.
  • This mobile end or wall 21a can be shaped.
  • the wall 21a can be moved between a first position, wherein said wall defines, inside the chamber 20, a volume almost equal to zero, and a second position, wherein said wall defines a volume equal to the final quantity of the filling product.
  • the enlarged head 22 slides instead along a second portion 19 of the hole housing.
  • the movement is driven and controlled by a cylinder 23 which applies a defined counter-pressure.
  • a stem 24 of the cylinder 23 abuts against the enlarged head 22 thus entering into the portion 19 of the hole housing of the die 17.
  • the cylinder 23 is provided with a numeric axis to control the length of the product while it is being manufactured.
  • the pressures P1 and P2 are adjusted in function of the chemical and physical characteristics of the product to be obtained.
  • the apparatus of figure 1 works as follows in order to realise the process of the invention.
  • the mobile ejector 21 is brought to its maximum lifted position to fill the first portion 20 of the hole housing and said ejector is held in said position by the fully extended stem 24 (figure 3).
  • the die 17 is locked in said position through the same extended stem 24 and the injection head 15 gets closer to the upper inlet of the die 17.
  • variable volume chamber 20 is at the zero or almost zero volume value, without any air contained inside said chamber. In this way, during the filling operation of said chamber, there is no need to let the air out and there is no formation of bubbles and of inclusions in the products which are being formed.
  • Figure 5 shows how, through a controlled feeding under pressure and counter-pressure, the filling of the upper portion 20 of the die is realised simultaneously with the withdrawal of the mobile ejector 21 and with the lowering of the stem 24 under counter-pressure. In this way, a controlled backward movement of the mobile wall 21a is realised.
  • Figure 8 shows, through a schematic view, a different configuration of the apparatus wherein a second group of the invention process phases can be realised.
  • the die 17 is aligned with a lower second cylinder 30 provided with a pulling out stem 31.
  • a support element 32 for a container or a stick 33 of the pastel 28, is positioned above the die 17 and is aligned therewith.
  • the stem 31 is put in action and the pastel 28 is pushed in order to be transferred into the cup 34 of the container 33 ( Figures 11 and 12).
  • the mobile wall 21a is moved from the second position, previously mentioned, to the first position, mentioned as well.
  • the product 28, i.e. the pastel, which has been held and cooled in the chamber 20 of the die 17, is transferred into the cup 34 of the final container 33 from the same side where the chamber 20 is fed by the filling product.
  • Figure 13 shows the phase wherein, once the transfer of the pastel 28 has been finished, the stem 31 is in its withdrawn position and the support element 32 of the container 33 is driven so as to leave and go away from the die 17 below.
  • Figure 14 shows the container correctly filled with the corresponding pastel 28.
  • Figure 15 shows how, through the rotation of part of the container along the direction of arrow 35, the pastel 28 can be pulled out from said container.
  • a flashing, a lacquering, a check or other operations to enhance the quality of the product can be performed.
  • the pastel is rotated in the direction opposite the arrow 35, i.e. in the direction of arrow 35 in figure 17, in order to have the pastel 28 return into the container 33.
  • the process of the invention realises simultaneously a casting and a certain level of compactness. This is achieved thanks to the injection pressure and to the counter-pressure on the mobile ejector.
  • the inner air is eliminated because the injection operation starts in a chamber having a volume equal to zero or almost zero since the volume wherein the product is injected has already been filled by the mobile ejector.
