    Use of a material in cosmetic packaging and system for dispensing a product under pressure comprising at least one part made of or comprising said material.
    The invention relates to the use of a material M in cosmetic packaging, in particular in fluid distribution systems.
    The invention also relates to a system for distributing a product under pressure, in particular intended to be part of a cosmetic packaging, comprising at least one part made of or comprising a material M.
    Distribution systems are known comprising a body provided with means for withdrawing a product packaged in a bottle to supply an internal chamber of said body. In particular, the distribution system can be in the form of a manually actuated pump or a valve making it possible to restore under pressure a product packaged in a bottle.
    Such a distribution system comprises a rod on which is mounted a push button to be actuated reversibly. The rod is fitted with a valve which is arranged in the internal chamber between a stable state of closure of a distribution path formed through said rod and of the push button up to a distribution orifice, and a state constrained by actuation of the rod in which said distribution path is in communication with the internal chamber for the pressurized outlet of the product.
    During its actuation, the rod is subjected to significant mechanical stresses which require the use of a material whose rigidity must be sufficient to prevent that, by deformation of said rod, the operation of the distribution system is impaired. In particular, such deformations can lead to a rupture of the rod as well as to a loss of tightness of the mounting on said rod of the valve and / or of the push button, these members generally being made of a more flexible material than that of the stem.
    The push button may have a housing into which a distribution path opens, a nozzle provided with a distribution orifice being mounted in said housing. Given the forces exerted by the pressure of the product in the distribution path, it is necessary to ensure the mechanical strength of the assembly of the nozzle, and of the rod in the push button.
    The requirements for good mechanical behavior are also valid for other elements of the distribution system such as the pump body.
    Certain elements of a distribution system such as the rod, the body and the nozzle are made from a polymer of the polyacetal family, in particular polyoxymethylene (POM), also known as acetal. In fact, the use of this type of material is satisfactory, in particular in terms of its mechanical and chemical properties, of sliding, of dimensional stability, of low moisture uptake.
    However, POM is now recognized as being able to present toxicological risks, mainly due to the release of formaldehyde during its hot injection into manufacturing molds, as well as during the destruction of distribution systems at end of life.
    In addition, various directives aim to regulate, control and limit the presence of substances potentially dangerous for human health in products, in particular cosmetics, which pushes cosmeticians to limit or even remove from their formulas the preservatives which are often the cause of allergies. or intolerance.
    Cosmetic products therefore become more and more fragile, being easily contaminated by bacteria and fungi and difficult withstanding in particular the contact of air which can for example cause drying or oxidation of the product.
    In some distribution systems, the pump body itself can participate in sealing. However, POM has a porosity which is too great to be able to contribute to the good conservation of the product before its distribution. Indeed, the air can diffuse through the POM in sufficient quantity to be able to contaminate and / or oxidize the product contained in the rod between two distributions, said product also being able to dry out by evaporation through said POM rod.
    Thus, a POM pump body does not have a satisfactory seal.
    In addition, in connection with regulatory and formulation changes in the products to be distributed, the pharmaceutical and cosmetic industries may have to sterilize their distribution systems to avoid any contamination of the product before its first distribution. In particular, a quick and effective way to sterilize a product distribution system is to expose it to gamma or beta irradiation, in that it allows in particular the sterilization of closed volumes.
    However, irradiation tends to modify the properties of POM, in particular by weakening it mechanically and causing it to change its appearance. Thus, the distribution systems of which certain elements such as the rod, the body or the nozzle are produced on the basis of POM must be sterilized under gas, in particular under ethylene oxide, this process proving to be less efficient and more complex to carry out. industrially implemented as conventional irradiation under gamma or beta rays.
    The use of POM as a cosmetic packaging material therefore has a series of drawbacks, in particular with regard to the release of toxic product. There is therefore a need to use a material which does not have the drawbacks of POM, this while retaining its mechanical and chemical properties in order to limit changes to industrial tools, in particular molds.
    The invention aims to solve these technical problems by proposing the use of a material M in cosmetic packaging, in particular for producing all or part of a fluid distribution system, said material M having similar mechanical and chemical properties. from those of POM but not releasing toxic products.
    The invention relates to the use of a material M in cosmetic packaging, in particular in fluid distribution systems intended to form part of cosmetic packaging, the material M being defined according to the following formula A:

    The present invention will be better understood in the light of the following description which is given for information only and which is not intended to limit said invention, accompanied by FIG. 1 showing in longitudinal section an example of a system of distribution of a product under pressure.
    In order to replace POM in certain cosmetic packaging, very many materials have been tested by the applicant. In particular, tests have been carried out on these different materials to determine if their mechanical and chemical properties are close to those of POM. Tests on the use of these materials for the manufacture of certain parts intended for cosmetic packaging were also carried out. Among these, a family of materials, defined by formula A presented above, made it possible to obtain very good results.
    The different materials of formula A have mechanical and chemical properties approaching those of POM, thanks to which the use of these new materials will not involve too significant modification of the manufacturing process of parts formerly made of POM.
    In particular, within this family, three types of material have been selected by the applicant for their mechanical and chemical properties: polyketones (POK), polybutylene terephthalate (PBT) and polyamides (PA).
    A polyamide (PA) is a polymer containing amide functions -C (= O) -NH- which may result from the polycondensation between the carboxylic acid and amine functions.
    Polyamides have properties close enough to POM to be used as a cosmetic packaging material. Many different polyamides can be used in cosmetic packaging. Mention may in particular be made of PA46, PA4T and PA410 which are particularly advantageous for this use.
    However, polyamides are difficult to use in a hot mold because they risk crosslinking inside the mold and therefore be difficult to unmold. The polyamides tested therefore require certain adjustments to the manufacturing process for parts intended for cosmetic packaging.
    Another material tested by the applicant is polybutylene terephthalate (PBT). PBT can be defined according to the following formula:
    PBT has mechanical characteristics equivalent to those of POM, especially in terms of mechanical resistance.
    PBT also has chemical properties equivalent to POM. PBT can be used in particular as a cosmetic packaging material because of its chemical compatibility with alcohol, a very common compound in fragrance and lotion.
    PBT also has good resistance to sterilization by beta and gamma rays. Indeed, the POM becomes brittle at around 15 kGy while the PBT resists sterilization up to around 50 kGy.
    Unlike POM, PBT does not release formaldehyde or any degradation product considered to be a dangerous and / or carcinogenic substance.
    However, the use of PBT in cosmetic packaging presents certain constraints, particularly in terms of compatibility with the tools currently used for POM.
    Indeed, PBT has a different shrinkage than that of POM. Withdrawal (plastic withdrawal) is the ability of a body to return to its normal state after a rise in temperature and / or plastic deformation. A small shrinkage is required to obtain parts of high dimensional precision, with tight tolerance.
    POM and PBT-based parts obtained after demolding therefore do not have the same dimensions due to the different shrinkages of material. In addition, PBT and POM do not react in the same way in temperature, so it is also necessary to organize the process in terms of thermal cycles.
    Another type of material tested by the applicant is polyketones (POK). An example of POK can be represented by the formula below:
    O
    The Young's elongation and elastic modulus of this material contribute to exceptional resistance to cyclic fatigue, in tension and in bending. This material is also more resistant to aging and creep than POM.
    POK also has good resistance to sterilization by beta and gamma rays, its properties not being deteriorated up to around 300 kGy.
    The POK meets regulatory requirements for the cosmetics sector and does not release formaldehyde or any degradation product considered to be a dangerous and / or carcinogenic substance.
    In addition, POK has a shrinkage similar to that of POM. Thus, the POK can be used for the manufacture of parts intended for cosmetic packaging using the same manufacturing process and the same tools as those used for POM.
    POK and POM can be used with the same process, the same injection temperature (for example 225-230 °) and the same mold temperature (for example 80 ° C). Both have a similar shrinkage and do not have a release problem. In particular, for POK no more than for POM, there is no problem of crosslinking of the polymer which would lead to trapping in the mold.
    Polyketones (POK) therefore seem to be the most suitable materials for use in cosmetic packaging, in particular using a production line previously used with POM.
    There are several types of polyketones (POK). The physicochemical tests mentioned above were carried out on POKs of formula A in which RI and R2, identical or different, each independently represent an ethylene group and / or a propylene group.
    The presence of a small proportion of propylene makes it possible to influence the crystallization of the product and to improve the mechanical properties of the polyketone by making it more resistant.
    Advantageously, the material M is a polyketone (POK) comprising less than 20% of propylene, or even 15%, even 10%.
    The POK identified as particularly advantageous with regard to the targeted results is marketed by AKRO-PLASTIC under the name of "AKROTEK®PK".
    Preferably, whatever the nature of the material M used in cosmetic packaging, in particular in fluid distribution systems intended to be part of cosmetic packaging, said material M selected according to the invention does not release any carcinogenic dangerous substance following its degradation.
    In order to be able to undergo sterilization by radiation, for example by beta and / or gamma radiation, the material M is selected so that its properties are not altered by Beta and / or Gamma irradiations up to at least 15 kGy.
    Advantageously, its properties are not altered by Beta and / or Gamma irradiations up to at least 250 kGy.
    Material M has thermal stability up to at least 200 ° C, so that it can be used in an existing manufacturing process.
    Advantageously, the material M has a shrinkage greater than or equal to 1.5% and less than or equal to 2.5%, so that it can be used in a process previously used for POM.
    The present invention also relates to a system for distributing a product under pressure, in particular intended to be part of a cosmetic packaging, said system comprising at least one part made of or comprising a material M defined above.
    In particular, said distribution system can comprise a pump produced from the material M. The material M can be, in particular, a polyketone (POK), polybutylene terephthalate (PBT) or a polyamide (PA).
    Advantageously, the material M is a polyketone (POK) of formula A in which RI and R2, identical or different, each independently represent an ethylene group and / or a propylene group.
    Still advantageously, said polyketone (POK) comprises less than 20% of propylene.
    Described below, with reference to FIG. 1, a distribution system with manual actuation to allow the distribution of a product under pressure, for example in the form of a spray, a hazelnut or a stream continuous depending on the nature of said product. In an example of application, the product is in the form of a liquid, a lotion, a gel or a cream, for cosmetic use, for perfumery or for pharmaceutical treatments.
    This system is given only by way of example and any system for dispensing a product under pressure known to a person skilled in the art may be suitable for the application of the present invention.
    The dispensing system of FIG. 1 comprises a dispensing pump arranged to restore a liquid product in the form of a spray. However, the invention is not limited to a particular type of distribution system, nor to a particular form of distribution.
    The pumps, made of porous materials of the POM type, are poor barriers to the evaporation of the constituents of the formulas, in particular perfumes. The most volatile constituents, that is to say the aromas, or the fragrance of perfumes, escape first through the porosities of materials.
    The pump according to the invention can be made in whole or in part from the material M. The material M can be, in particular, a polyketone (POK), polybutylene terephthalate (PBT) or a polyamide (PA).
    Advantageously, the material M is a polyketone (POK) of formula A in which RI and R2, identical or different, each independently represent an ethylene group and / or a propylene group.
    Still advantageously, said polyketone (POK) comprises less than 20% of propylene.
    POK has a very good barrier thanks to its low porosity. The shelf life of perfumes and cosmetics in a pump made from POK is therefore improved.
    The pump comprises a body 1 in which an internal chamber 2 is formed which is supplied with product from a source, said body being equipped with means allowing the supply of said internal chamber. To do this, the body 1 has a supply orifice 3, for example equipped with a dip tube 4, which is intended to be in communication with the interior of a bottle for packaging the product for its removal.
    The body 1 of the pump can also be made from the material M. In particular, the body 1 can be made from polyketone (POK), butylene polyterephthalate (PBT) or polyamide (PA).
    The body 1 can be equipped with a peripheral hoop 5 allowing the sealed mounting of said body in the neck of a bottle by putting the supply orifice 3 in communication with the product packaged in said bottle. According to the embodiment shown, the hoop 5 is deformable, for example by being made of aluminum, to ensure its sealed crimping around the neck. However, the invention is not limited to a particular embodiment of the mounting of the dispensing system on the bottle, which can in particular be achieved by screwing, welding or tight snap-fastening.
    The distribution system comprises a rod 6 for supplying the pressurized product which is arranged in the body 1 while being reversibly actuatable in translation over a stroke respectively of distribution and suction of said product by means of a push button 7 which is mounted on said rod.
    The rod 6 is equipped with an exhaust valve 8 which is disposed in the internal chamber 2 having a stable state of closure of a distribution path formed through the rod 6 and the push button 7 to a dispensing orifice 9, and a state constrained by actuation of said rod in which said dispensing path is in communication with said internal chamber.
    Thus, the product is dispensed by digital pressing on the push button 7 to move it axially by actuating the translation of the rod 6 in order to convey the product from the internal chamber 2 to the dispensing orifice 9 through which said product fate.
    Given the various constraints it has to undergo in the context of its use, the rod 6 is made from a material whose rigidity is sufficient to prevent the operation of the distribution system by deformation of the said rod. is altered. In addition, the material of the rod 6 must have satisfactory sliding and resistance to wear and creep properties. To do this, the material of the rod 6 comprises at least one material M of formula A.
    The material M can be, in particular, a polyketone (POK), polybutylene terephthalate (PBT) or a polyamide (PA).
    Advantageously, the material M is a polyketone (POK) of formula A in which RI and R2, identical or different, each independently represent an ethylene group and / or a propylene group.
    Still advantageously, said polyketone (POK) comprises less than 20% of propylene.
    The use of a material M also makes it possible to contribute to good preservation of the product to be dispensed. Indeed, the porosity of this material proves to be sufficiently low to prevent air and water from diffusing through the rod 6, thus limiting the contamination, the drying and / or the oxidation of the product contained in said rod between two distributions. Furthermore, the material M retains its properties, in particular mechanical and appearance, under irradiation by gamma or beta rays, which makes it possible to envisage rapid and effective sterilization of the distribution system.
    Consequently, a bottle according to the invention is particularly advantageous for dispensing a product whose content of preservatives is limited or even zero and / or which has to be sterilized.
    In addition, the use of a material M makes it possible to limit the toxicological risks, in particular in that it is not likely to release toxic component during its heating or its destruction at the end of life. Furthermore, the rod 6 made of a material M, can be produced by molding, using tools and injection steps conventionally used for the members of a distribution system using POM.
    The distribution path passes through an internal channel 10 formed in the rod 6, said channel being in communication with two upstream radial orifices 11 and opening into the upper end of said rod. The push button 7 has a well 12 which is mounted around the upper end of the rod 6 in order to pass the distribution path through the internal channel 10 and said well.
    The push button 7 has a housing 13 into which the distribution path opens, a nozzle 14 provided with the distribution orifice 9 being mounted in said housing. The nozzle 14 is in communication with the mounting well 12 via a channel 15 provided in the push button 7, the distribution path passing through said channel.
    According to the embodiment shown, the distribution path opens into a vortex chamber 16 which is formed between the nozzle 14 and a bearing surface 17 of the housing 13, said vortex chamber being provided with the distribution orifice 9. This embodiment makes it possible to make very quickly rotate the liquid product in the vortex chamber 16 to restore said product in the form of a spray through the dispensing orifice 9. As a variant, in particular in the case of a more viscous product, the nozzle 14 may be under the form of an extension tube.
    Given the forces exerted by the pressure of the product in the distribution path, in particular of the order of 5 to 7 bars, it is necessary to ensure the mechanical strength of the mounting of the nozzle 14 and of the rod 6 in the button push-button 7. To do this, the assemblies are produced by fitting, the nozzle 14 being further equipped with a radial projection 18 forming harpooning means in the housing 13.
    The nozzles must have a very good hold in the bodies of push buttons so as not to be catapulted under the outlet pressure when the pump is used by a consumer. For this, they are traditionally made of POM and then harpooned in the softer material of the body of the push button, such as for example a polyolefin, in order to check the test pressure of 30 bars.
    However, during the positioning of the nozzle in the housing of the pump body, the harpoons are planed or at least blunt, and the holding of the nozzle is thereby reduced. With the POK, the profile of the harpoons remains identical and the holding is then much better.
    To avoid the risk of expulsion of the nozzle 14 during dispensing, said nozzle can therefore be made from a material M. The material M can be, in particular, a polyketone (POK), butylene polyterephthalate ( PBT) or a polyamide (PA).
    Advantageously, the material M is a polyketone (POK) of formula A in which RI and R2, identical or different, each independently represent an ethylene group and / or a propylene group.
    Still advantageously, said polyketone (POK) comprises less than 20% of propylene.
    In addition, at least the part of the button forming the housing 13 can be made of polyolefin to present a flexibility promoting good harpooning of the rigid projection 18.
    Furthermore, at least the part of the button forming the well 12 can be made of polyolefin not loaded with COC (cyclic olefin copolymer) to have a rigidity less than that of the rod 6 in order to promote the mechanical strength and the tightness mounting between the push button 7 and said rod.
    In the embodiment shown in FIG. 1, the valve 8 of the rod 6 comprises a piston 19 which is mounted coaxially around said rod by presenting an external sealing surface 20 which is in sealed support in the internal chamber 2 for form between said piston and the supply orifice 3 a metering chamber for the product. The piston 19 also has an internal sealing surface 21 which can be actuated in displacement relative to at least one upstream orifice 11 of the distribution path.
    The piston 19 has a sleeve 22 for sliding assembly around the rod 6, said assembly being arranged to allow the reversible movement of the internal sealing surface 21 between a stable state of closure and a constrained state of opening of the communication. of the distribution path with the internal chamber 2. In a variant not shown, the actuation of the internal sealing surface 21 between its two states can be achieved by deformation of the piston 19.
    The piston 19 can be made of a more flexible material than that of the rod 6 and of the body 1 in order to ensure the sealing of the internal chamber 2 at the level of the outer sealing surfaces 20 and interior 21, while being able to benefit a low coefficient of friction between said rod and said piston.
    The pump comprises a spring 23 which is arranged in the internal chamber 2, between the rod 6 and the body 1, to return said rod to a stable state after being actuated on its dispensing stroke. In particular, the rod 6 is equipped with a lower stop 24 added on which the spring 23 is supported.
    A trend calls for pumps made entirely of thermoplastic materials. However, the pumps include a return spring whose force can be equal to approximately 2 kg. To make such a spring, it is necessary to use a helical spring generally made of steel wire. Until then, no plastic could achieve the performance of a steel spring.
    However, the material M has mechanical and chemical properties allowing it to be used to produce such a cylindrical spring. Thus, said spring 23 can be made from a material M. The material M can be, in particular, a polyketone (POK), polybutylene terephthalate (PBT) or a polyamide (PA).
    Advantageously, the material M is a polyketone (POK) of formula A in which RI and R2, identical or different, each independently represent an ethylene group and / or a propylene group.
    Still advantageously, said polyketone (POK) comprises less than 20% of propylene.
    Such a polyketone makes it possible to produce cylindrical springs of identical performance to those made of metallic wire, perfectly compatible with the perfume and cosmetic formulas, and perfectly clean, which is not the case with metallic springs which can never be completely washed with wire drawing oils.
    In addition, the sliding of the piston 19 is constrained by a pre-compression spring 25 which is mounted in abutment between the sleeve 22 and a radial projection 26 of the rod 6, said precompression spring exerting a force of plating of the range d 'inner seal 21 against the lower stop 24 to ensure the sealed closure of the upstream ports 11 between two distributions.
    To have sufficient resistance to creep and to mechanical stresses, the lower stop 24 can be made of a material M similar to that of the rod 6, that is to say based on a material M.
    Furthermore, the supply orifice 3 is surmounted by a seat 27 with respect to which an intake valve in the form of a ball 28 is reversibly movable between an open state of said seat to allow the supply of the internal chamber 2 and a state of closure of said seat.
    To allow optimum sealing in the closed state, the intake valve and the seat 27 can be made of materials having different rigidities. For example, the seat 27 can be more flexible than the intake valve.
    The invention has been described above with the aid of embodiments without limitation of the general inventive concept.
    Many other modifications and variations suggest themselves to those skilled in the art, after reflecting on the various embodiments illustrated in this application. These embodiments are given by way of example and are not intended to limit the scope of the invention, which is determined exclusively by the claims below.
