Definitions

  • the present invention relates to a product distributor packaged in liquid form, and more particularly intended for cosmetic, dermatological, pharmaceutical, ophthalmic applications or perfumery. It relates more particularly to a distributor comprising a bottle or product reservoir, and an end valve closure member and / or a pump with nozzle, whose surfaces in contact with the active ingredient have been designed to filter and treat the air entering the tank.
  • the product is packaged in a flexible, deformable pocket forming a reservoir, connected to a pump without recovery air, commonly known as an "airless" pump.
  • a pump without recovery air commonly known as an "airless” pump.
  • the latter is attached to a bottle rigid, thereby trapping the flexible pouch inside the bottle.
  • the bag contracts by reducing its capacity by a volume equivalent to the volume withdrawn, and thus inducing a deformation of the reservoir.
  • the product is packaged in a cylindrical bottle, the bottom of which is provided with a movable follower piston.
  • the piston rises in the bottle thus reducing the capacity of the bottle by one volume equivalent to the volume withdrawn.
  • Glass bottles therefore contain liquid products with a filling rate of 50% compared to the total volume of the bottle, in order to guarantee at the end of emptying the pressure threshold of 0.5 bar.
  • the major drawback of this embodiment lies in the ratio unfavorable between the useful volume and the total volume and therefore in the additional cost generated by the packaging volume.
  • the disadvantage of this embodiment lies in the fact that the air is passed through the wall of the bottle, then through the liquid, this which has the effect of slowing the air diffusion and the replacement speed of the dose taken.
  • the present invention aims to solve all of the problems techniques related to the embodiments previously described, by proposing a filtration and treatment system for the return air flow, which overcomes so-called "airless" preservation systems and offers filtered air, free of bacteria and / or with modification of the oxygen level.
  • This distributor which is not limited to liquids and creams, allows a filling rate between 90 and 99% of the total volume of the tank.
  • the dispenser comprises a product reservoir connected by one of its ends to a head provided with a pump equipped with a controlled means for closing the vent made on the body of said pump and a fixing sleeve; said sealing means comprising an air permeable diffusion element containing non-migrant agents for bacteriological and / or chemical treatment of air by contact; characterized in that said element is fitted on the pump body and retained by peripheral radial tightening watertight at least one annular zone on the one hand, and by engagement of its part high in the fixing sleeve, on the other hand.
  • Patent publication EP-A-0 189 549 proposes a dispensing bottle according to the preamble of claim 1.
  • the diffusion element is a porous core forming an annular section filter which is fitted directly onto the pump body and whose pore size is between 5 ⁇ m and 10 ⁇ m.
  • the average porosity of the diffusion element is substantially equal to 7 ⁇ m, with a void rate between 40 and 60%;
  • the diffusion element is an elastically deformable sleeve delimiting around the pump body a flexible pocket of variable volume and the membrane wall of which is made with a material of intrinsic air permeability of between 300 and 5000 mm 3/24 h.
  • said material also contains fillers porous.
  • the material constituting the diffusion element contains antioxidant, bactericidal treatment agents, antiseptic, atmosphere modifier in independent or combined form.
  • the diffusion element used in the dispenser of the invention does not constitute a physical barrier preventing the passage of bacteria as in earlier distributors, but forms either a filter or a membrane providing a significant exchange surface for the incoming air for its treatment bacteriological and / or chemical by contact within the element with agents non-migrants.
  • both the dimensions of the filter pores and the permeability selective membrane combined with the surface tension properties of materials used prohibit the passage of liquids, which makes the element of hydrophobic diffusion and prevents bacterial proliferation in the tank.
  • Figure 1 is a sectional view, in elevation of a first mode of realization of the invention.
  • Figure 2 is a sectional view, in elevation, of a second mode of realization of the invention.
  • the dispenser of the invention comprises a reservoir 1 containing the produces 2 in the form of a liquid, cream or gel.
  • This tank 1 preferably rigid or flexible, comprises at one of its ends a head provided with a end valve or air return pump 4 with a cover or nozzle 5.
  • the body 41 of the pump 4 is extended downwards by a dip tube 42 bathing in product 2.
  • the head further includes a locked fixing sleeve 3 on the end of the tank 1 for example, by snap-fastening and in which is trapped the upper edge 4 la of the body 41 of the pump 4.
  • the body 41 of the pump 4 which is of the atmospheric type, comprises therefore a vent hole 40 which makes it possible to replace the withdrawn dose of product liquid 2, in tank 1, by an equivalent volume of air, thus restoring equal pressure between the surrounding environment and the interior of the tank 1.
  • the body 41 of the pump 4 has at the vent hole 40 a controlled closure means.
  • This closure means which is intended to mask the hole 40, comprises an element air permeable 6 and containing non-migrant agents for the bacteriological and / or chemical treatment of air, by contact.
  • Element 6 preferably cylindrical-conical like body 41, is fitted on this body and is retained there, in the closed position of the vent 40, by tight radial peripheral tightening of at least one annular zone, on the one hand, and by engagement of its upper part in the fixing sleeve 3, on the other hand.
  • the bacteriological and / or chemical agents are chosen to provide treatment bactericide, antiseptic, antioxidant or atmosphere modifier (dehumidifier) by contact. These agents are non-migrants, i.e. they remain fixed within the polymer network of the material constituting the diffusion element.
  • the diffusion element cylindroconical 6 consists of a porous core 61 of annular section forming filter which is fitted directly onto the body 41 of the pump 4.
  • the element 61 has, for a pump body 41 whose height is 21 mm, a height of 2 to 10 mm and preferably 7 mm and a thickness of 2 to 3 mm and preferably 2.3 mm.
  • the element 61 is in radial clamping over its entire height over body 41.
  • the average pore size is between 5 and 10 ⁇ m and preferably between 7 to 10 ⁇ m with a vacuum rate between 40 and 60%.
  • the diffusion element 61 offers a large exchange surface between the air and the porous material constituting the filter which contains the treatment.
  • the path of the air containing the bacteria is therefore relatively long and narrow, which ensures sufficient contact time to make the effective bacteriological and / or chemical air treatment.
  • the pore dimensions are less than or equal to 10 ⁇ m, which, combined with the use of plastics such as polyethylene and / or polypropylene, prohibits the passage of liquids and thus avoids any risk of bacterial growth in the reservoir 1.
  • the upper part 61a of the porous core 61 has a profile and a geometry adapted to the upper part of the socket 3.
  • the fixing sleeve 3 comprises a crown internal cylindrical 30 which covers the upper end of the reservoir 1 in being in tight contact with the internal wall. Crown 30 extends towards the high by a shoulder 31 delimiting a hooking zone for the upper edge 41a of the body 41 of the pump 4.
  • the upper part of the core 61 comprises a constriction 61a which comes lodge in a complementary manner in the space provided under the edge 41a of the body 41 inside the crown 30.
  • the diffusion element 6 is consisting of an elastically deformable cylindroconical sleeve 62, delimiting around the body 41 of the pump 4 a flexible pocket 60 of variable volume.
  • the wall of the pouch 60 thus forms a membrane made with an intrinsic permeability material in the air between 300 and 5000 mm 3/24 h.
  • the air volume of the bag 60 at rest is between 100 mm 3 and 800 mm 3 for a pump body whose height is 21 mm and thus offers an exchange surface of between 3 and 10 cm 2 .
  • the upper part of the sleeve 62 has a cylindrical skirt 62a of greater thickness which is tightly engaged inside the crown 30 of the socket 3.
  • the lower part of the sleeve 62 has an area annular 62b in sealed peripheral radial tightening around the body 41 of the pump 4.
  • the sleeve 62 is made, for example, with silicone, polypropylene or polyethylene or mixtures thereof.
  • the element 6, especially when it is in the form of an annular core by a molding operation simultaneous with that of the pump body.
  • the three-dimensional network of selected macro-molecules forming the annular core pores 61 allows the diffusion of filtered air, but prevents passage contaminants and / or denaturants for the product contained in the tank.
  • the tank By the choice of its constituent materials, the tank is rigid and therefore retains its shape and volume after distribution of the product. expulsion of the product generates a vacuum in the tank and therefore a differential of pressure between inside and outside of the tank. This pressure differential ensures the distribution towards the inside of the distributor of a corresponding volume of air the volume of liquid product discharged with a flow rate which depends on the characteristics of permeability and dimensions of the diffusion element.
  • the present invention offers multiple advantages because it allows reduce the toxicity of the product contained in the tank by the absence of agents antibacterial and / or oxygen preservatives.
  • Use of the dispenser according to the invention is therefore carried out in a sterile manner, with volume compensation sampled, thus making it possible to offer a useful volume of up to 99% and without affect the efficiency of the pump.
