Definitions

  • the present invention relates to a device for the extemporaneous mixing of two products according to the preamble of claim 1.
  • the invention is particularly suitable for mixing two products, one of which is in powder form or of high viscosity (which go up to that of a cream), such as the products sometimes used in the field of perms or hair coloring. Other applications however can be considered.
  • a mixing zone which offers a large exchange surface between the two products.
  • the mixing zone is devoid of any "dead” zone able to retain and isolate a portion of one and / or the other of the front components mixing, which makes it possible to produce a perfectly homogeneous mixture.
  • the all the products are mixed, which allows the proportions to be respected required, and to offer a mixture whose properties are optimized, and correspond to those announced.
  • the first product is a non-liquid product, in the form in particular a powder or a product with high viscosity, such as a cream.
  • the volume defined by the intermediate element is at least equal by volume of said second product, contained in the upper container, the first product occupying before mixing, substantially the entire volume of the pot. So, in the case where the first product is highly oxidizable in air, the risks of deterioration of it are reduced.
  • the section of the volume defined by the pot and by the element intermediate is substantially straight over its entire height, even varying so progressive in one direction or the other (increasing or decreasing). Variation is however preferably light. A slight variation can mean a variation of a few mm over a height of about 10 cm. In other words, the mixing zone defined by the pot and the intermediate element, does not have any sensitive bottleneck, or any sudden change in section which could affect the successful completion of the mix.
  • the closure means comprise a plug carried by an axial skirt located near the second end of the element intermediate, and a free edge of which defines said opening.
  • the cap can be mounted on the axial skirt by snap-fastening.
  • the means for causing the expulsion of the obturation member can include a rod carried by a surface of the plug located inside the intermediate element, said rod being suitable, during assembly of the pot on the element intermediate, to come into engagement with a projecting member disposed axially in the bottom of the pot, and to cause the expulsion of the stopper.
  • the rod is centered on the axis of the device.
  • the rod is slightly in length less than the axial height of the intermediate element, so that before being mounted on the pot, the intermediate element can rest on a flat surface without causing the expulsion of the obturation member.
  • the first end of the intermediate element is mounted tightly on the opening of the pot by screwing.
  • a collar is formed near the opening of the pot, said neck comprising a thread on a external surface, and intended to cooperate with a corresponding thread provided on an internal surface of the intermediate element, in the vicinity of the first end, an internal skirt with an external diameter slightly smaller than the diameter internal of the neck being carried by the first end of the intermediate element of so as to ensure a tight mounting of the pot on the intermediate element.
  • the second end of the intermediate element is tightly mounted on the second end of the upper container, by screwing.
  • a neck is formed at the near the second end of the upper container, said neck comprising a thread on an external surface, and intended to cooperate with a thread corresponding provided on an internal surface of the intermediate element, at near the second end, an internal skirt with an external diameter slightly smaller than the internal diameter of the neck being carried by the second end of the intermediate element so as to ensure a tight mounting of the upper container on the intermediate element.
  • the pot Before being mounted on the intermediate element, for the realization of the mixture, the pot is closed with a screw cap. Alternatively, we could provide a seal or heat-sealed by any other appropriate means.
  • the dispensing tip can be screwed onto the first end of the container upper, the orifice being closed by a breakable tab, to be broken before the distribution of the mixture.
  • the orifice is closed by a plug screwed.
  • the mixture can be a hair application product.
  • the second product can be an oxidizing product in liquid form, the first product being a dye in the form of a cream or powder.
  • the mixing device 1 illustrated in FIG. 1A has a longitudinal axis X and includes an upper container 2 (intended to contain the oxidant).
  • a first end 38 of container 2 is surmounted by a neck 3 whose external surface has a thread 4 able to cooperate with a corresponding thread 5 carried by a distribution nozzle 6.
  • the tightness of the installation of the distribution nozzle on the container 2 is reinforced by the presence of a skirt 7 carried by said tip.
  • the dispensing nozzle 6 has an outlet orifice 8 which, before the first use, is closed by a breakable tab 9.
  • the dispensing nozzle is made of polypropylene
  • the container upper 2 is made of polyethylene.
  • the lower end 10 of the container 2 is open, and forms a wide neck opening 11 on the outer surface of which a thread 12 is produced, suitable for cooperate with a corresponding thread 13 provided on the inner surface of a intermediate element 14, in the vicinity of its upper end 15.
  • the intermediate element 14 also comprises in the vicinity of the end upper 15 a transverse annular wall 39 carrying a sealing skirt 16, concentric with the side wall of the intermediate element 14, and diameter smaller than the diameter of said side wall, so as to define with the side wall of the intermediate element, in the vicinity of the second end 15, an annular U-shaped groove for forcibly receiving the free edge of the neck 11.
  • the external diameter of the sealing skirt 16 is slightly less than the internal diameter of the neck 11 of the container 2.
  • a snap ring 17 can be provided to ensure that the upper container 2 / element arrangement cannot be dismantled intermediate 14, and strengthen the tightness of the assembly.
  • Another skirt 18, from diameter smaller than the diameter of the sealing skirt 16, is also formed in the vicinity of the upper end of the intermediate element 14.
  • This skirt 18 is carried by the transverse annular wall 39 and has a free edge 19 defining an opening 20, removably closed by a plug retractable 21.
  • the plug 21 is mounted by snap on the axial skirt 18.
  • the shutter 21 can be made of polyethylene or polypropylene.
  • the intermediate element has a substantially cylindrical body 23 of height axial greater than the axial height of the container 2.
  • the lower end 22 of the intermediate element 14, opposite the end 15, is also open.
  • She has a skirt 24, in slight external recess, relative to the body 23, and the internal surface of which has a thread 25, capable of cooperating with a thread 26 carried by the outer surface of the upper end of the container 27.
  • a snap bead may also be provided to ensure, after screwing the container 27 onto the intermediate element 14, the the assembly thus produced.
  • the thread 26 of the container 27 is carried by one end 32, forming a neck in very slight internal recess relative to the body 29 of the container.
  • the opening 30 delimited by the free edge 31 of the container 27 is of section substantially equal to the section of the pot 27.
  • the opening of the pot 30 is of section substantially equal to the section of the opening delimited by the free edge of the sealing skirt 28.
  • the intermediate element 14 can be made in polypropylene (PP).
  • the pot 27 has at its bottom 35, a protruding member 36, and suitable, as we will see it in more detail later, coming in engagement with the free end a rod 37 carried by the lower surface of the plug 21, which engagement causes the plug to be expelled and the mixture to be made.
  • the rod 37 is of axial height slightly less than the axial height of the element intermediate 14 so that the upper container 2 / element arrangement intermediate 14 can be placed upright on a flat surface without risking cause the accidental expulsion of the plug 21.
  • the presence of the organ in projection 36 in the bottom of the pot limits the axial height of the element intermediate 14.
  • the member 36 can be obtained by molding with the container 27.
  • the member 37 can be obtained by molding with the shutter 21.
  • the pot 27 is obtained from molding of plastic materials chosen from polyvinyl chlorides, or from a complex of type materials polyethylene terephthalate (PET) / polyethylene (PE), or polyethylene (PE) / ethylene vinyl alcohol (EVOH) / polyethylene (PE).
  • PET polyethylene terephthalate
  • PE polyethylene
  • EVOH ethylene vinyl alcohol
  • container 27 contains the dye, in the form of a cream or a powder.
  • the mixture is without having to compress the walls of the container that contains the cream or powder.
  • the cream (or powder) may therefore be contained in a semi-rigid or rigid structure, which allows better conservation.
  • the pot 27 is sealed by a cover 33, which is screwed and comprises a sealing skirt 34 of the type of sealing skirts 28 or 16 discussed previously.
  • the cover 33 can be made of polypropylene.
  • the intermediate element 14 is of sufficient height so that everything the liquid contained in the container 2 can flow under the wall portion transverse annular (39) carrying the skirts 16 and 18.
  • the volume delimited by the pot 27 and the intermediate element 14 is greater than or equal the volume of the mixture.
  • the volume circumscribed by the intermediate element 14 is at least equal to the volume of liquid contained in the upper container 2.
  • the mixture can then be applied by means of the dispensing nozzle 6 after breaking the breakable tab 9.
  • the product outlet is favored by pressing on the walls of the container 2.
