Description

PULVERISATEUR NASAL NASAL SPRAYER
La présente invention concerne un pulvérisateur nasal et plus particulièrement un perfectionnement de la tête de distribution d'un tel dispositif. Ces pulvérisateurs sont principalement destinés au traitement des maladies ou des maux touchant la région rhinopharyngée (rhumes, rhinites, sinusites...).The present invention relates to a nasal sprayer and more particularly to an improvement of the dispensing head of such a device. These sprayers are mainly intended for the treatment of diseases or ailments affecting the nasopharyngeal region (colds, rhinitis, sinusitis ...).
Les pulvérisateurs traditionnels comprennent un réservoir de produit actif liquide équipé de moyens de pressurisation et/ou de dosage destinés à coopérer avec une tête de distribution. Cette tête est pourvue d'au moins un conduit d'éjection débouchant à son extrémité externe sur une buse de pulvérisation et communiquant à son extrémité interne avec le réservoir via les moyens de pressurisation.Traditional sprayers comprise a reservoir of liquid active product equipped with pressurization and / or metering means intended to cooperate with a dispensing head. This head is provided with at least one ejection conduit opening at its external end onto a spray nozzle and communicating at its internal end with the reservoir via the pressurization means.
Cependant, la tête de ces pulvérisateurs ne comporte qu'un seul embout de telle sorte que le traitement nécessite de procéder successivement à une pulvérisation dans chaque narine en obturant simultanément l'autre narine.However, the head of these sprayers has only one tip so that the treatment requires successively spraying into each nostril while simultaneously closing the other nostril.
La présente invention a pour but de résoudre, ce problème technique de manière satisfaisante. Ce but est atteint selon l'invention au moyen d'un pulvérisateur nasal du type précédent dans lequel la tête de distribution comprend deux embouts juxtaposés comportant chacun au moins un conduit d'éjection dont les extrémités sont séparées d'une distance correspondant sensiblement à l'écartement moyen des deux narines et qui sont fixés sur une embase de liaison avec le réservoir.The present invention aims to solve this technical problem satisfactorily. This object is achieved according to the invention by means of a nasal sprayer of the preceding type in which the dispensing head comprises two juxtaposed nozzles each comprising at least one ejection duct whose ends are separated by a distance corresponding substantially to the 'average spacing of the two nostrils and which are fixed on a connection base with the reservoir.
Selon un mode de réalisation préférentiel, les deux embouts sont identiques et comportent chacun un conduit d'éjection qui s'étend de façon axiale au moins dans sa partie terminale.According to a preferred embodiment, the two end pieces are identical and each comprise an ejection duct which extends axially at least in its terminal part.
Selon une caractéristique avantageuse, les conduits d'éjection des deux embouts se rejoignent en partie basse pour former un conduit unique d'alimentation.According to an advantageous characteristic, the ejection conduits of the two end pieces meet at the bottom to form a single supply conduit.
Selon une première variante, le conduit est constitué d'un alésage central de ladite embase.According to a first variant, the conduit consists of a central bore of said base.
Selon une seconde variante, le conduit d'alimentation est constitué d'un manchon central faisant saillie à l'intérieur de ladite embase . Selon un mode de réalisation avantageux, ladite tête est constituée d'une première pièce portant les deux embouts et destinée à être assemblée avec une seconde pièce portant l'embase .According to a second variant, the supply duct consists of a central sleeve protruding inside said base. According to an advantageous embodiment, said head consists of a first part carrying the two end pieces and intended to be assembled with a second part carrying the base.
De préférence, les deux pièces délimitent alors entre elles la partie basse des conduits d'éjection.Preferably, the two parts then delimit between them the lower part of the ejection conduits.
Selon une autre variante, la première pièce comporte une jupe inférieure externe destinée à venir en serrage radial étanche avec une portée interne cylindrique réalisée à la partie supérieure de la seconde pièce. Selon encore une autre variante, la face inférieure de la première pièce et/ou la face supérieure de la seconde pièce comportent une rainure délimitant au moins partiellement la paroi de la partie basse des conduits d'éjection.According to another variant, the first part comprises an external lower skirt intended to come in tight radial tightening with a cylindrical internal bearing produced at the upper part of the second part. According to yet another variant, the lower face of the first part and / or the upper face of the second part have a groove defining at least partially the wall of the lower part of the ejection conduits.
Selon une autre caractéristique, ladite embase supporte deux noyaux en colonnes destinés à être engagés axialement dans la partie terminale des conduits d'éjection de façon à définir une section transversale annulaire.According to another characteristic, said base supports two column cores intended to be engaged axially in the terminal part of the ejection conduits so as to define an annular cross section.
Selon encore une autre caractéristique, la partie basse des conduits d'éjection est inclinée par rapport aux axes des embouts. Selon une disposition avantageuse, les deux embouts ont un profil sensiblement tronconique à bords d'extrémités curvilignes.According to yet another characteristic, the lower part of the ejection conduits is inclined relative to the axes of the end pieces. According to an advantageous arrangement, the two end pieces have a substantially frustoconical profile with edges of curvilinear ends.
Le pulvérisateur de l'invention est particulièrement ergonomique et permet d'améliorer et de simplifier le traitement thérapeutique. La tête de distribution à deux embouts s'adapte, en outre, aux moyens de pressurisation et aux réservoirs traditionnels sans qu'il soit nécessaire de leur apporter une quelconque modification.The sprayer of the invention is particularly ergonomic and makes it possible to improve and simplify the therapeutic treatment. The dispensing head with two nozzles adapts, moreover, to pressurization means and to traditional reservoirs without it being necessary to make any modification to them.
Au surplus, le mode de réalisation en seulement deux pièces est particulièrement facile à fabriquer et à assembler, ce qui le rend très fiable et très économique.In addition, the embodiment in only two pieces is particularly easy to manufacture and assemble, which makes it very reliable and very economical.
Ainsi, quelle que soit la forme des moyens de pressurisation et de dosage, le volume de produit actif délivré est réparti en deux flux par le biais de la tête à deux embouts, ce qui permet d'obtenir un traitement simultané des deux narines. L'invention sera mieux comprise à la lecture de la description qui va suivre accompagnée des dessins sur lesquels : - les figures la et lb représentent des vues en élévation respectivement de face et de profil d'un mode de réalisation du pulvérisateur de l'invention ;Thus, whatever the form of the pressurization and metering means, the volume of active product delivered is divided into two flows by means of the head with two nozzles, which makes it possible to obtain simultaneous treatment of the two nostrils. The invention will be better understood on reading the description which follows, accompanied by the drawings in which: - Figures la and lb show elevation views respectively from the front and side of an embodiment of the sprayer of the invention;
- la figure 2 représente une vue en coupe de la tête de distribution selon le mode de réalisation des figures la et lb ;- Figure 2 shows a sectional view of the dispensing head according to the embodiment of Figures la and lb;
- la figure 3 représente une vue en coupe de la tête de distribution selon un autre mode de réalisation de l'invention, montée sur un réservoir.- Figure 3 shows a sectional view of the dispensing head according to another embodiment of the invention, mounted on a tank.
Le pulvérisateur nasal représenté sur les figures la et lb comprend un réservoir R contenant un produit actif liquide.The nasal spray represented in FIGS. 1a and 1b comprises a reservoir R containing a liquid active product.
Le réservoir R est équipé de moyens de pressurisation et/ou de dosage P, tel qu'une pompe, destinés à coopérer avec une tête de distribution T.The reservoir R is equipped with pressurization and / or metering means P, such as a pump, intended to cooperate with a dispensing head T.
La tête T est pourvue de manière traditionnelle, d'au moins un conduit d'éjection débouchant à son extrémité externe sur une buse de pulvérisation (non apparente sur les figures la,lb) et communiquant à son extrémité interne avec le réservoir R via les moyens de pressurisation P (représentés sur la figure 3).The head T is conventionally provided with at least one ejection duct opening at its outer end onto a spray nozzle (not visible in FIGS. 1a, 1b) and communicating at its inner end with the reservoir R via the pressurization means P (shown in Figure 3).
Selon l'invention, la tête T comprend deux embouts la, lb juxtaposés et fixés sur une embase 2 assurant la liaison avec le réservoir R.According to the invention, the head T comprises two nozzles 1a, 1b juxtaposed and fixed on a base 2 ensuring the connection with the reservoir R.
Les extrémités des embouts la, lb sont séparées d'une distance correspondant sensiblement à l'écartement moyen des deux narines.The ends of the tips 1a, 1b are separated by a distance corresponding substantially to the average spacing of the two nostrils.
Dans les modes de réalisation des figures les deux embouts la,lb sont identiques avec un profil sensiblement tronconique à bords d'extrémité curvilignes favorisant l'introduction dans les narines.In the embodiments of the figures the two end pieces 1a, 1b are identical with a substantially frustoconical profile with curvilinear end edges favoring the introduction into the nostrils.
Un appui manuel sur les rebords plats 2a de l'embase 2 provoque l'actionnement des moyens de pressurisation P et/ou de dosage et entraîne la pulvérisation du produit actif dans les narines via les conduits d'éjection des embouts la, lb et la buse.Manual support on the flat edges 2a of the base 2 causes the actuation of the pressurization means P and / or metering and causes the active product to be sprayed into the nostrils via the nozzle ejection conduits la, lb and the nozzle.
Dans le mode de réalisation représenté en coupe sur les figures 2 et 3 chaque embout la, lb comporte un conduit d'éjection 10a, 10b s'étendant de façon axiale au moins dans la partie terminale, en amont de la buse de pulvérisation B. Les conduits d'éjection 10a, 10b des deux embouts la, lb se rejoignent en partie basse pour former un conduit unique d'alimentation 20.In the embodiment shown in section in FIGS. 2 and 3, each nozzle 1a, 1b has an ejection conduit 10a, 10b extending axially at least in the terminal part, upstream of the spray nozzle B. The ejection conduits 10a, 10b of the two nozzles 1a, 1b meet at the bottom to form a single supply conduit 20.
Le conduit d'alimentation 20 est constitué sur la figure 2 d'un alésage central de l'embase 2 et sur la figure 3 d'un manchon central faisant saillie à l'intérieur de ladite embase.The supply conduit 20 consists in FIG. 2 of a central bore of the base 2 and in FIG. 3 of a central sleeve projecting inside said base.
