Definitions

  • the present invention relates to a packaging device according to the preamble of claim 1 and a pouch according to the preamble of claim 18. It finds more particularly its use in the field of packaging devices for sensitive cosmetic products, of liquid to pasty consistency, such as coloring and / or bleaching oxidants, skincare creams, or sunscreens, which must be brought into contact with the air only when they are used. Indeed, the contact with the air generates reduction reactions degrading said cosmetics, which makes them ineffective at the time of their use.
  • devices with a bottle are usually used inside which a deformable inner bag is arranged, the product being stored inside the bag.
  • these devices are then equipped with means for dispensing the product without air intake.
  • To ensure flexibility of these bags generally made of plastic material, they are generally made thin.
  • pockets whose wall is formed by a complex structure, at least tri-layer.
  • the complex structure then forms a laminated laminated material comprising a first impervious layer made of a first material, for example polyethylene, and a second impermeable layer made of a second material, for example polyamide, distinct from the first material.
  • the two layers are then glued to each other by means of a third uniform and intermediate layer of binder or glue to allow adhesion between these two first layers.
  • This complex structure is then cut in the form of panels, the panels are then assembled together to form said pocket.
  • tubes or flasks used in particular in cosmetics, are made of thermoplastic material.
  • polyolefins are used, which are recyclable and non-polluting.
  • the polyolefin packages are prepared by extrusion, more particularly by extrusion blow molding, as taught in the document. US 4179251 .
  • the bottle is made of PVC and the inner bag is made of polyethylene.
  • Polyolefins have good gas and water impermeability properties and have the advantage of being compatible with most chemicals.
  • micro-hole means a hole such that the impermeability of a surface in which it is made is no longer ensured locally and brutally, relative to the overall impermeability of said surface. Indeed, when the packages are made by extrusion blow molding, micro-holes, caused by impurities in the plastic at the time of its transformation, appear. The appearance of these micro-holes is all the more important as the thickness of the wall made is fine.
  • the invention is sought to manufacture such a device according to a manufacturing method, simple, easy to implement and inexpensive, preferably using the same manufacturing process to form the bottle and the inner bag of the device.
  • a leakproofness test of a pocket consists in placing the pocket cavity in overpressure, and then measuring, after a determined period of time, the variation of the pressure inside the pocket. If no decrease in the inner pressure of the pocket is observed, then the pocket is considered non-leaking. The problem with performing such tests is that they do not allow effective detection of leaks.
  • a device according to the preamble of claim 1 is known from US 4,265,949 .
  • the subject of the invention is a packaging device for which the bottle and the inner bag can in particular be obtained by the same method, and such that the need to test the tightness of the internal bag can be overcome by choosing a structure of this inner layer to ensure the absence of micro-holes.
  • the process for obtaining the bag and the bottle is extrusion blow molding.
  • the bag being flexible, to allow a retraction of the bag on itself, inside the bottle, it is essential that during the manufacturing process, there is no adhesion between the inner wall of the bottle. bottle and the outer wall of the pocket.
  • the bottle is made of a first material
  • the inner bag is made of a second material.
  • the first material is incompatible with the second material.
  • the innovative structural feature of the pocket consists of providing a pocket whose wall comprises at least two layers contiguous to each other, without the intermediary of binder or glue, to remain at the same time simple while guaranteeing the absence of micro-holes .
  • the subject of the invention is a packaging device according to claim 1.
  • direct physicochemical reaction it is understood that the reaction that occurs between the materials, under given temperature and pressure conditions, allows the joining and the adhesion of the layers to one another, the layers being respectively formed from each of these materials.
  • Direct physicochemical reactions exclude reactions requiring the use of a binder between the materials.
  • the physicochemical reactions take place at temperatures close to the melting temperatures of the different materials. It is then a question of heat-sealing or thermofusion of the materials of the different layers together.
  • the inner bag has only layers made of the same material and directly contiguous to each other.
  • each of the two layers comprises at least 80% of its mass represented by the same compound or several compounds of the same chemical family, in all cases the compound (s) chosen (s) for the realization of each of these layers all belong to the same chemical family.
  • chemical family is meant a group of molecules characterized by the presence of a particular chemical function on each of the molecules of the group.
  • the two layers are physico-chemically compatible with each other and adhere perfectly to each other. one to another. They remain welded to each other to form, after cooling, the wall of the inner bag.
  • said chemical family is chosen from one of the following chemical families of thermoplastic polymers: the family of polyolefins, the family of polyvinyl chloride and their derivatives, the family of styrenics, the family of polyoxymethylenes, the family of polyamides, the family of saturated polyesters, the family of polycarbonates, the family of sulfonic polymers, the family of polyphenylene oxides, the family of cellulosics, and the family of polyurethanes.

  • the two coextruded layers of the inner bag are made from the same compound, representing more than 80% of their mass.
  • This same compound is for example from the family of polyamides, and in this case, preferably polyamide 11.
  • the two coextruded layers of the inner bag are each made from two distinct compounds, nevertheless from the same chemical family.
  • a first layer of this internal pocket comprises at least 80% of a compound of the family of polyamides, for example polyamide 6,6, whereas a second layer of this internal pocket comprises, it, at least 80% of another compound of this family of polyamides, for example polyamide 11.
  • one of the layers forming the inner bag has a charge, colored or not, so as to color or opaque said layer of the inner bag.
  • This change in appearance of one of the layers makes it possible to form a means for detecting the presence of the internal bag in the bottle.
  • the pocket if it is colored, is easier to detect by cameras installed on the production line and whose images are analyzed in real time on the production line.
  • adjuvants or other molecules with properties such as antistatic, can be incorporated into the composition of said layers.
  • Additives may represent up to 20% by weight of the composition of each of the layers of the inner bag.
  • Another advantage of placing the coloring filler, or any other type of additive, in only one of the layers of the bag is to make it possible to save on the amount of coloring filler or additive to be used.
  • the coloring filler and / or additives are incorporated into the composition of the inner layer of the bag, which layer does not come into contact with the inner wall of the bottle, said inner layer possibly coming into contact with the product to be stored.
  • This arrangement also makes it possible to avoid interference with the inner wall of the bottle, and in particular makes it possible to avoid adhesion phenomena, which are not desired, and solely caused by the presence of these additives or dyes.
  • the inner bag is obtained by an extrusion blow molding process.
  • the inner bag and the bottle are coextruded simultaneously through the same extrusion blow molding process.
  • the bottle may also be made of a material comprising at least one compound of one of the chemical families of thermoplastic polymers mentioned above.

  • the bottle is made from a material having a low adhesion with an outer layer of the inner bag, especially during the extrusion blow molding process, to ensure non-adhesion between the outer layer of the inner bag and a inner wall of the bottle.
  • the bottle may be made from a compound selected from the family of polyolefins, and the bag is then made from one or more compound (s) chosen (s) in the family of polyamides. More particularly, the bottle may be made of high density polyethylene, and at least one of the layers of the inner bag with at least 80% by weight of polyamide 11.
  • the wall of the inner bag has a thickness of between 1/10 and 3 / 10th of a millimeter.
  • the thicknesses of the different layers may be equal to each other, or different, and in the latter case, the outer layer is generally thicker than the inner layer.
  • the inner bag has an opening arranged so that it is circumscribed in the opening of the bottle.
  • the product can be inserted and removed from the device through these openings.
  • the product is stored in the inner bag.
  • the device is provided with a dispensing means, for example of the type of pumps without air intake, generally called “airless” pumps.
  • airless pumps are widely used, especially in the field of cosmetics for the distribution of care products in the form of a single phase, usually liquid, including body milks, moisturizers or sunscreen products.
  • Such dispensers are particularly advantageous in that they make it possible in particular to keep the product isolated from the air. Due to their instability in the presence of air, staining and / or discoloration products Capillary can be advantageously distributed by such pump systems without air intake.
  • the pump may be of the piston, membrane or valve type. Such pumps are well known, and therefore require no further detailed description.
  • the volume of the bag of the bottle on which it is mounted decreases by a value corresponding to the volume of the dispensed dose, so that the product occupies, throughout the life of the device, substantially all the available volume of the internal pocket.
