Abstract

A container, especially a bottle (1) with a dispensing head (3) and a cap (5), an airless pump (4) and a valve in the dispensing head. All or part of the container's wall is made from a plastic material with a high level of air permeability, such as an injectable thermoplastic polymer e.g. polyolefins, PVC or technical polymers. The base of the container can be made from a material which is highly permeable to air, e.g. a silicone elastomer, or the container wall can be loaded with a material which enhances air diffusion, such as chalk. The portions of the container in contact with the dispensing head or cap are treated with an anti-oxidant or antiseptic contact agent which does not migrate into the solution.

Description

La présente invention est relative à un dispositif de distribution d'un produit, conditionné sous forme d'un liquide, particulièrement destiné à des applications cosmétiques, dermatologiques, pharmaceutiques ou ophtalmiques et tout produit de parfumerie. Elle vise plus particulièrement un flacon ou récipient de distribution pour produit liquide pourvu d'un organe de fermeture à clapet d'extrémité et/ou d'une pompe avec embout, dont les surfaces en contact avec le principe actif ont été conçues afin d'autoriser le passage de l'air par diffusion à travers les parois du flacon.The present invention relates to a device for dispensing a product, packaged in the form of a liquid, particularly intended for cosmetic, dermatological, pharmaceutical or ophthalmic applications and any perfume product. It relates more particularly to a bottle or dispensing container for liquid product provided with a closure member with an end valve and / or with a pump with nozzle, the surfaces of which in contact with the active principle have been designed in order to allow the passage of air by diffusion through the walls of the bottle.

De manière connue, les flacons de distribution sont constitués par un récipient rigide ou souple, contenant le produit à distribuer et une tête de distribution formant clapet ou pompe. Les parois de ces flacons sont élaborées dans un matériau étanche au milieu environnant, généralement de l'air et de l'eau, afin d'éviter, d'une part une altération du produit contenu par l'air et d'autre part d'éviter une diffusion du produit au travers des parois. Il est donc nécessaire de prévoir sur ces flacons une mise à l'air libre, généralement placée sur le corps de pompe ou sur la tête du clapet, pour compenser le volume de liquide qui a été expulsé à l'extérieur.In known manner, the dispensing bottles consist of a rigid or flexible container, containing the product to be dispensed and a dispensing head forming a valve or pump. The walls of these bottles are made of a material that is impermeable to the surrounding environment, generally air and water, in order to avoid, on the one hand, an alteration of the product contained by the air and, on the other hand, '' avoid diffusion of the product through the walls. It is therefore necessary to provide on these bottles an air vent, generally placed on the pump body or on the valve head, to compensate for the volume of liquid which has been expelled outside.

Le principal inconvénient des flacons de distribution connus de l'art antérieur, réside principalement dans le fait qu'ils comportent une mise à l'air libre par des moyens mécaniques. Cela implique :

  • une perte de stérilité pour le liquide, d'où la présence nécessaire de conservateurs antibactériens ;
  • un risque d'oxydation pour le produit, d'où la présence d'antioxydants ;
  • une fonction de mise à l'air libre qui complique la réalisation de la tête de distribution.
The main drawback of the dispensing bottles known from the prior art, lies mainly in the fact that they include venting by mechanical means. That implies :
  • loss of sterility for the liquid, hence the necessary presence of antibacterial preservatives;
  • a risk of oxidation for the product, hence the presence of antioxidants;
  • a venting function which complicates the production of the dispensing head.

La présente invention vise donc à pallier ces inconvénients en proposant un flacon de distribution pourvu d'une tête équipée d'un clapet ou d'une pompe "airless" (sans reprise d'air) dont les mécanismes sont dépourvus de dispositif de mise à l'air libre, cette dernière s'effectuant par diffusion au travers d'une paroi du flacon.The present invention therefore aims to overcome these drawbacks by proposing a dispensing bottle provided with a head fitted with a valve or with an "airless" pump (without air intake), the mechanisms of which are devoid of setting device. open air, the latter being effected by diffusion through a wall of the bottle.

A cet effet, le flacon de distribution d'un produit, conditionné sous forme d'un liquide, particulièrement destiné à des applications cosmétiques, dermatologiques, pharmaceutiques, ophtalmiques ou tout produit de parfumerie, comprenant un récipient contenant le produit à distribuer, connecté par l'une de ses extrémités à une tête pourvue d'une pompe "airless" ou d'un clapet, se caractérise en ce que tout ou partie des parois du flacon est réalisé dans un matériau plastique, disposant d'une perméabilité à l'air très élevée, afin de permettre le passage de l'air au travers des parois du flacon.To this end, the dispensing bottle for a product, packaged in the form of a liquid, particularly intended for cosmetic, dermatological, pharmaceutical, ophthalmic or any perfume product, comprising a container containing the product to be distributed, connected by one of its ends with a head provided with an "airless" pump or a valve, is characterized in that all or part of the walls of the bottle is made of a plastic material, having a permeability to very high air, to allow the passage of air through the walls of the bottle.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description faite ci-après, en référence au dessin unique annexé qui en illustre un exemple de réalisation dépourvu de tout caractère limitatif. Sur la figure unique :

  • la figure unique est une vue en coupe, en élévation latérale, du flacon objet de l'invention.
Other characteristics and advantages of the present invention will emerge from the description given below, with reference to the single appended drawing which illustrates one of them. exemplary embodiment devoid of any limiting character. In the single figure:
  • the single figure is a sectional view, in side elevation, of the bottle object of the invention.

Selon un mode préféré de réalisation du flacon, objet de l'invention, il comporte un récipient 1 contenant la solution sous forme de liquide à distribuer. Cette enceinte préférentiellement rigide ou souple, comprend à l'une de ses extrémités un système de distribution 3 pouvant être un clapet d'extrémité ou une pompe "airless" 4 avec un capot 5, le corps de la pompe "airless" baignant dans le liquide.According to a preferred embodiment of the bottle, object of the invention, it comprises a container 1 containing the solution in the form of liquid to be dispensed. This preferably rigid or flexible enclosure comprises at one of its ends a distribution system 3 which may be an end valve or an "airless" pump 4 with a cover 5, the body of the "airless" pump immersed in the liquid.

Selon une caractéristique avantageuse de l'invention, tout ou partie des parois de l'enceinte, en particulier les parois latérales, est élaboré dans un matériau plastique, notamment des polymères thermoplastiques injectables tels que des polyoléfines, du PVC, des polymères techniques, et dont les propriétés de perméabilité à l'air sont élevées, afin de permettre le passage de l'air au travers des parois de l'enceinte.According to an advantageous characteristic of the invention, all or part of the walls of the enclosure, in particular the side walls, is produced from a plastic material, in particular injectable thermoplastic polymers such as polyolefins, PVC, technical polymers, and whose properties of air permeability are high, in order to allow the passage of air through the walls of the enclosure.

Selon un mode préféré de réalisation, on obtient un flacon selon l'invention :

  • soit par moulage, à l'aide d'un procédé d'injection soufflage de matériau de type plastique comme ceux décrits précédemment, auxquels on ajoute une charge, celle-ci pouvant être une matière qui permet d'augmenter la diffusion de l'air, notamment de la craie ;
  • soit par un procédé de bi-injection, l'une des parties du flacon, notamment le corps, étant moulée à partir d'une matière plastique, comme celle précédemment décrite, le fond 2 étant obtenu par un moulage dans une matière possédant des propriétés de très grande perméabilité à l'air, comme par un exemple un élastomère silicone.
According to a preferred embodiment, a bottle according to the invention is obtained:
  • either by molding, using an injection-blowing process of plastic type material such as those described above, to which a filler is added, the latter being a material which makes it possible to increase the diffusion of air , including chalk;
  • either by a bi-injection process, one of the parts of the bottle, in particular the body, being molded from a plastic material, like that previously described, the base 2 being obtained by molding in a material having properties very large air permeability, as for example a silicone elastomer.

Le réseau tridimensionnel des macromolécules choisies permet la diffusion de l'air, mais évite le passage d'agents contaminant pour le produit contenu dans le récipient, notamment des bactéries.The three-dimensional network of selected macromolecules allows the diffusion of air, but prevents the passage of contaminating agents for the product contained in the container, in particular bacteria.

Quel que soit le procédé d'élaboration, le fond et le corps sont assemblés par des moyens connus (encliquetage, soudure par ultrasons, par vibrations) de manière à conformer un récipient qui autorise une diffusion de l'air à travers l'une des parois, notamment celle formant le fond.Whatever the production process, the bottom and the body are assembled by known means (snap-fastening, ultrasonic, vibration welding) so as to form a container which allows air to diffuse through one of the walls, in particular that forming the bottom.

Le récipient, objet de l'invention, est surmonté d'une tête de distribution munie d'un clapet ou d'une pompe, qui permet de distribuer le liquide contenu dans le flacon. De par le choix de ses matériaux constitutifs, le flacon acquiert de la rigidité et conserve donc sa forme et son volume après distribution du produit. L'expulsion du produit génère une dépression dans le volume du récipient, qui favorise la diffusion d'un volume d'air correspondant au volume de liquide manquant au travers de la paroi perméable.The container, object of the invention, is surmounted by a dispensing head provided with a valve or a pump, which makes it possible to dispense the liquid contained in the bottle. By the choice of its constituent materials, the bottle acquires rigidity and therefore retains its shape and volume after dispensing the product. The expulsion of the product generates a vacuum in the volume of the container, which promotes the diffusion of a volume of air corresponding to the volume of liquid missing through the permeable wall.

Selon une caractéristique avantageuse de l'invention, la captation des molécules d'oxygène au travers du réseau tridimensionnel des macromolécules est améliorée par l'ajout dans ce dernier d'absorbeurs d'oxygène.According to an advantageous characteristic of the invention, the capture of oxygen molecules through the three-dimensional network of macromolecules is improved by the addition in the latter of oxygen absorbers.

Grâce aux propriétés des parois, la reprise d'air s'effectue de façon stérile, sans risque de pollution bactérienne, sans reprise d'oxygène en cours d'utilisation.Thanks to the properties of the walls, the air intake takes place in a sterile manner, without risk of bacterial pollution, without oxygen uptake during use.

Selon une autre caractéristique avantageuse de l'invention, les zones en contact de tout ou partie des différentes pièces de la tête de distribution 3 munie d'une pompe "airless" 4 ou d'un clapet, avec le produit à distribuer, sont traitées de manière à fixer sur ces dernières un agent de contact antioxydant et/ou antiseptique, non migrant, c'est-à-dire restant fixé sur le polymère.According to another advantageous characteristic of the invention, the areas in contact with all or part of the different parts of the dispensing head 3 provided with an "airless" pump 4 or a valve, with the product to be dispensed, are treated so as to fix on the latter an antioxidant and / or antiseptic, non-migrating contact agent , that is to say remaining fixed on the polymer.

Ainsi, selon une première méthode, on effectue le dépôt d'un métal, notamment choisi parmi l'argent, le cuivre, le zinc, le mercure, par électrodéposition sur les différentes pièces métalliques ou plastiques.Thus, according to a first method, a metal, in particular chosen from silver, copper, zinc, mercury, is deposited by electrodeposition on the various metallic or plastic parts.

Selon une deuxième méthode, le traitement antibactérien est effectué à l'aide d'un procédé de greffage entre un composé organo-métallique (notamment choisi parmi le sel d'argent, de cuivre, de zinc, de mercure, de plomb) ou organique, et un support hydrocarboné de préférence macromoléculaire, notamment un polymère.According to a second method, the antibacterial treatment is carried out using a grafting process between an organometallic compound (in particular chosen from silver, copper, zinc, mercury, lead salt) or organic , and a hydrocarbon support, preferably macromolecular, in particular a polymer.

Par procédé de greffage, on réalise une réaction chimique entre le produit à greffer et le support, de façon qu'ils soient liés chimiquement l'un à l'autre. Le produit, dans notre cas l'agent antibactérien, est accroché de façon stable sur le support et ne peut pas migrer ou se décrocher du support dans la solution qui est distribuée par l'intermédiaire dudit dispositif, objet de l'invention.By grafting process, a chemical reaction is carried out between the product to be grafted and the support, so that they are chemically bonded to each other. The product, in our case the antibacterial agent, is stably hung on the support and cannot migrate or detach from the support in the solution which is distributed via said device, object of the invention.

Le greffage est effectué notamment à l'aide de rayonnements ionisants, du type alpha, bêta ou gamma. L'agent antibactérien à greffer et les surfaces du support sont en contact entre eux et sous l'action de l'énergie des rayonnements ionisants, ils réalisent des liaisons chimiques stables.The grafting is carried out in particular using ionizing radiation, of the alpha, beta or gamma type. The antibacterial agent to be grafted and the surfaces of the support are in contact with each other and under the action of the energy of ionizing radiation, they create stable chemical bonds.

Il est important qu'à la fois les surfaces des différentes pièces à greffer et les molécules du produit de l'agent antibactérien disposent chacune de structures chimiques comprenant des carbones tertiaires, des carbones insaturés ou tout groupe chimique pouvant être ionisé par les rayonnements ionisants, formant ainsi des radicaux libres qui interagissent entre eux.It is important that both the surfaces of the different parts to be grafted and the molecules of the product of the antibacterial agent each have structures chemicals comprising tertiary carbons, unsaturated carbons or any chemical group which can be ionized by ionizing radiation, thus forming free radicals which interact with each other.

Pour les deux procédés décrits ci-dessus, on procède ensuite au lavage des supports des pièces greffées pour éliminer l'excès d'agent antibactérien qui n'est pas fixé chimiquement auxdites surfaces.For the two methods described above, the supports for the grafted parts are then washed to remove the excess of antibacterial agent which is not chemically fixed to said surfaces.

Selon une troisième méthode, les différentes pièces en matière plastique sont moulées en présence d'un agent antibactérien non soluble, notamment de l'argent incorporé dans la matière plastique au moment du moulage.According to a third method, the various plastic parts are molded in the presence of an insoluble antibacterial agent, in particular silver incorporated in the plastic material at the time of molding.

Dans ce cas, un moulage de polyéthylène en présence de 1 % en poids d'un agent antibactérien à base d'argent, réalise une protection efficace vis-à-vis du milieu contaminant (une population de 50.000 individus d'Echerichia Coli est réduite en 6 heures de temps, à moins de 10 individus).In this case, a molding of polyethylene in the presence of 1% by weight of an antibacterial agent based on silver, achieves effective protection against the contaminating medium (a population of 50,000 individuals of Echerichia Coli is reduced in 6 hours time, to less than 10 individuals).

Les flacons, objet de l'invention, selon les matières plastiques choisies pour leur élaboration, disposent soit de parois perméables souples, soit de parois perméables rigides, pour des configurations respectivement à clapet ou à pompe.The bottles, object of the invention, according to the plastics chosen for their preparation, have either flexible permeable walls, or rigid permeable walls, for valve or pump configurations respectively.

Tout ou partie des éléments formant la pompe "airless", le clapet, l'embout, est traité par une protection antibactérienne de contact.All or part of the elements forming the "airless" pump, the valve, the nozzle, is treated with an antibacterial contact protection.

La présente invention offre de multiples avantages car elle permet de réduire la toxicité du produit contenu dans le récipient de par l'absence d'agents conservateurs antibactériens et/ou antioxygènes, l'utilisation d'un flacon selon l'invention s'effectue donc de manière stérile.The present invention offers multiple advantages because it makes it possible to reduce the toxicity of the product contained in the container due to the absence of antibacterial and / or antioxidant preservatives, the use of a bottle according to the invention is therefore carried out. sterile.

Il demeure bien entendu que la présente invention n'est pas limitée aux exemples de réalisation décrits et représentés ci-dessus, mais qu'elle en englobe toutes les variantes.It remains to be understood that the present invention is not limited to the exemplary embodiments described and shown above, but that it encompasses all variants thereof.
