Description

La présente invention concerne un distributeur de produit liquide equipé d'un dispositif de reprise d'airThe present invention relates to a liquid product dispenser equipped with an air intake device

Les distributeurs de produit liquide sont généralement équipés d'un réservoir rigide et d'une pompe atmosphérique pourvue notamment d'un corps cylindroconique et d'une collerette de support coopérant, le cas échéant, avec une coupelle ou une douille d'assemblage sertie sur le col du réservoir en prenant appui sur un joint d'étanchéité enserrant le corps de pompe.The liquid product dispensers are generally equipped with a rigid reservoir and an atmospheric pump provided in particular with a cylindroconic body and a support flange cooperating, where appropriate, with a cup or an assembly sleeve crimped onto the neck of the tank by bearing on a seal enclosing the pump body.

La distribution d'une dose de produit créé, dans le réservoir de contenance fixe une dépression qu'il faut compenser par une reprise d'air de volume correspondant. A cet effet, les corps de pompe sont pourvus d'orifices dits d'évent susceptibles de faire communiquer le volume intérieur du réservoir avec l'extérieur lors de la phase finale de la distribution.The dispensing of a dose of product created, in the capacity tank fixed a depression that must be compensated by a return of air of corresponding volume. For this purpose, the pump bodies are provided with so-called vent ports that can communicate the interior volume of the reservoir with the outside during the final phase of the distribution.

Un autre mode de réalisation permettant de rétablir l'équilibre des pressions nécessaires au bon fonctionnement du distributeur consiste à prévoir un jeu entre la collerette de fixation et/ou le corps de pompe, d'une part, et le col du réservoir et/ou la coupelle d'assemblage, d'autre part de façon à permettre un débit d'aspiration d'air. Le US 3596808 décrit un distributeur selon le préambule de la revendication 1.Another embodiment for restoring the equilibrium of the pressures necessary for the proper operation of the dispenser consists in providing a clearance between the fastening flange and / or the pump body, on the one hand, and the neck of the reservoir and / or the assembly cup, on the other hand to allow a suction air flow. The US 3596808 discloses a dispenser according to the preamble of claim 1.

Cependant dans tous les modes de réalisation connus, les moyens formant évent sont le siège de fuites de produit liquide surtout lorsque le niveau du produit se trouve au-dessus de l'évent, soit par construction, soit par un usage spécifique du distributeur, en position renversée.However, in all known embodiments, the vent means are the seat of leaks of liquid product especially when the level of the product is above the vent, either by construction or by a specific use of the dispenser, in overturned position.

La présente invention a pour but de résoudre ces problèmes techniques de manière satisfaisante sans modifier la structure des distributeurs traditionnels.The present invention aims to solve these technical problems satisfactorily without changing the structure of traditional distributors.

Ce but est atteint, selon l'invention, au moyen d'un distributeur selon la revendication 1.This object is achieved, according to the invention, by means of a distributor according to claim 1.

Selon un mode de réalisation, ledit épaulement tronconique est porté par un collier emmanché sur ledit corps de pompe.According to one embodiment, said frustoconical shoulder is carried by a collar fitted on said pump body.

Selon une caractéristique avantageuse, ledit anneau présente au moins une fente radiale s'étendant à partir du bord libre pour faciliter sa déformation.According to an advantageous characteristic, said ring has at least one radial slot extending from the free edge to facilitate its deformation.

Selon une variante, la face interne dudit anneau comporte une rainure périphérique de calage destinée à recevoir une nervure aménagée sur le pourtour supérieur du réservoir.According to a variant, the inner face of said ring has a circumferential wedging groove for receiving a rib formed on the upper periphery of the reservoir.

Le distributeur de l'invention permet d'assurer une reprise d'air suffisante tout en assurant une herméticité du distributeur.The dispenser of the invention ensures a sufficient air intake while ensuring a hermeticity of the dispenser.

La souplesse et élasticité du joint annulaire peuvent être ajustées en fonction du niveau de dépression susceptible d'être créé créée dans le réservoir par la distribution du produit.The flexibility and elasticity of the annular seal can be adjusted according to the level of depression that can be created created in the reservoir by the distribution of the product.

La semi-étanchéité dynamique du distributeur est obtenue selon l'invention par l'effet de clapet résultant de la coopération entre l'anneau et l'épaulement.The dynamic semi-sealing of the distributor is obtained according to the invention by the valve effect resulting from the cooperation between the ring and the shoulder.

Le distributeur de peut utiliser des pompes à précompression munies ou non d'orifice d'évent, sans qu'il soit nécessaire de modifier leur structure.The dispenser can use pre-compression pumps with or without a vent port, without the need to change their structure.

L'invention sera mieux comprise à la lecture de la description qui va suivre en référence aux dessins sur lesquels :

  • la figure 3 représente une vue en perspective du joint annulaire plat utilisé dans l'invention.
The invention will be better understood on reading the description which follows with reference to the drawings in which:
  • the Figure 1A represents a sectional view of an embodiment of the dispenser of the invention in the rest position;
  • the Figure 1B represents a sectional view of the dispenser of the Figure 1A in the air intake phase;

  • the Figure 2B represents a sectional view of the dispenser of the Figure 2A in the air intake phase;
  • the figure 3 represents a perspective view of the flat annular seal used in the invention.

L'invention est destinée à être utilisée dans des distributeurs de produit liquide pour assurer, après chaque distribution, la reprise d'air dans un réservoir rigide R (représenté partiellement sur les figures) contenant le produit liquide.The invention is intended to be used in liquid product dispensers to ensure, after each distribution, the return of air into a rigid tank R (shown partially in the figures) containing the liquid product.

Ce distributeur est équipé d'une pompe P atmosphérique pourvue notamment d'un corps cylindroconique C surmonté d'une collerette de support S fixée sur le col au réservoir R en prenant appui sur un joint d'étanchéité enserrant le corps C.This dispenser is equipped with an atmospheric pump P provided in particular with a cylindroconic body C surmounted by a support flange S fixed on the neck to the tank R by bearing on a seal enclosing the body C.

Le distributeur représenté comporte, en outre, un bouton-poussoir K porté par une tête de distribution T montée sur le tube-gicleur de lia pompe P ainsi qu'une douille métallique d'assemblage D sertie à la fois sur la collerette S de la pompe et sur le col du réservoir R en emprisonnant le joint d'étanchéité.The dispenser shown further comprises a pushbutton K carried by a dispensing head T mounted on the nozzle-tube of the pump P and an assembly metal sleeve D crimped both on the collar S of the pump and on the tank neck R by trapping the seal.

Le distributeur représente comprend un anneau plat 1 formant joint, pourvu d'un bord libre 10 susceptible de se déformer élastiquement sous l'effet d'une dépression interne pour permettre la reprise d'air dans le réservoir R. La face interne de l'anneau 1 comporte une rainure de calage 12 destinée à recevoir une nervure N de profil complémentaire ménagée sur le pourtour supérieur du réservoir R.The distributor comprises a flat ring 1 forming a seal, provided with a free edge 10 capable of elastically deform under the effect of an internal vacuum to allow the return of air into the reservoir R. The inner face of the ring 1 comprises a wedging groove 12 intended to receive a rib N of complementary profile formed on the upper periphery of the reservoir R.

Dans le mode de réalisation des figures 1A et 1B, l'épaulement tronconique 20 est réalisé directement par moulage d'une seule pièce avec la paroi latérale externe du corps C de la pompe P.In the embodiment of Figures 1A and 1B , the frustoconical shoulder 20 is made directly by molding in one piece with the outer side wall of the body C of the pump P.

Toujours dans ce mode de réalisation, la pompe P est munie d'un orifice d'évent E traversant la paroi du corps C au-dessus de l'épaulement 20 et débouchant au-dessus de l'anneau 1 à l'intérieur de la douille D.Still in this embodiment, the pump P is provided with a vent orifice E passing through the wall of the body C above the shoulder 20 and opening above the ring 1 inside the socket D.

Comme représenté sur la figure 1A, lorsque la pompe P est au repos en position de fermeture, le bord libre 10 de l'anneau 1 est en appui étanche vers l'extérieur qui est ici vers le haut sous l'épaulement tronconique 2.As shown on the Figure 1A when the pump P is at rest in the closed position, the free edge 10 of the ring 1 is sealingly pressed towards the outside which is here upwards under the frustoconical shoulder 2.

Dans cette position le bord libre 10 est fléchi vers l'intérieur, et, ici vers le bas, sous contraintes, en ayant une portion de sa face externe 11 en contact avec l'épaulement 20.In this position the free edge 10 is bent inwards, and here downward under stress, having a portion of its outer face 11 in contact with the shoulder 20.

Après distribution d'une dose de produit, le bouton-poussoir K remonte avec le tube-gicleur de la pompe P en créant une dépression à l'intérieur du réservoir R.After dispensing a dose of product, the push button K rises with the nozzle tube of the pump P creating a vacuum inside the tank R.

Cette dépression provoque la déformation élastique du bord libre 10 de l'anneau 1 vers l'intérieur du réservoir R.This depression causes the elastic deformation of the free edge 10 of the ring 1 towards the inside of the reservoir R.

En quittant son appui contre l'épaulement 20, le bord libre 10 de l'anneau 1 libère un passage intercalaire autorisant l'aspiration d'un volume d'air compensateur en provenance de l'atmosphère extérieure via l'intérieur du corps de pompe et l'orifice d'évent E, comme représenté par les flèches sur la figure 1B.By leaving its support against the shoulder 20, the free edge 10 of the ring 1 releases an intermediate passage allowing the suction of a volume of compensating air from the outside atmosphere via the inside of the pump body and the vent port E, as represented by the arrows on the Figure 1B .

Dans le mode de réalisation des figures 2A et 2B la pompe P est dépourvue d'orifice d'évent. Dans ce cas, l'épaulement tronconique 20 est porté par un collier 2 emmanché sur le corps C de la pompe.In the embodiment of Figures 2A and 2B the pump P is devoid of vent orifice. In this case, the frustoconical shoulder 20 is carried by a collar 2 fitted on the body C of the pump.

De préférence, le collier 2 vient en butée vers le haut contre la collerette S.Preferably, the collar 2 abuts upwards against the collar S.

Dans la variante représentée, la partie inférieure du collier 2 portant l'épaulement 20 est en serrage radial étanche avec la paroi latérale externe du corps C tandis que la partie supérieure cylindrique délimite avec le corps C un espace libre intercalaire.In the variant shown, the lower part of the collar 2 carrying the shoulder 20 is in tight radial clamping with the outer side wall of the body C while the cylindrical upper portion delimits with the body C an interspace free space.

Comme représenté sur la figure 2B, lors de la phase de remontée du bouton-poussoir K, la reprise d'air s'effectue par l'extérieur du corps de pompe, entre la douille D et la collerette S puis via le passage libéré sous épaulement 20, par la déformation du bord libre 10 de l'anneau 1.As shown on the Figure 2B during the up phase of the pushbutton K, the air intake is effected by the outside of the pump body, between the bushing D and the flange S and via the passage released under the shoulder 20, by the deformation of the free edge 10 of the ring 1.

La figure 3 représente un mode de réalisation de l'anneau plat 1 utilisé dans le dispositif de l'invention.The figure 3 represents an embodiment of the flat ring 1 used in the device of the invention.

Pour améliorer sa souplesse l'anneau 1 présente au moins un et ici trois fentes 13 qui s'étendent radialement à partir du bord libre 10 et facilitent sa déformation élastique.To improve its flexibility, the ring 1 has at least one and here three slots 13 which extend radially from the free edge 10 and facilitate its elastic deformation.

La longueur des fentes est comprise entre un tiers et la moitié de la largeur de l'anneau 1The length of the slots is between one-third and one-half the width of the ring 1
