Abstract

The distribution head (1) is integral with a valve flap (3) of a valve (4) intended to be fixed to a housing containing the product to be distributed. The head is provided with a movable cap (11) presenting a clearance (13) facing the distribution orifice (9). A spring (12) is mounted between the cap and the head. The cap is provided with a flexible blade (17) of which the bent extremity (20) obturates, when at rest, the distribution orifice. When pressing the cap (11), the flexible blade (17) clears the distribution orifice (9) before the opening of the valve. Inversely, when relieving the pressure, the cap goes up again after closure of the valve and the flexible blade (17) closes the distribution orifice.

Description

La présente invention a pour objet une tête de distribution pour produit semi-liquide, visqueux ou pâteux destinée à être montée sur une enceinte de conditionnement d'un tel produit, montée sur une valve, solidaire du clapet de cette valve et munie d'un conduit débouchant latéralement à l'extérieur par un orifice de distribution, la tête étant actionnable par pression en comprimant un ressort de valve. Une telle tête de distribution est connue par le document FR-A-1572537.The present invention relates to a dispensing head for semi-liquid, viscous or pasty product intended to be mounted on a packaging enclosure of such a product, mounted on a valve, integral with the valve of this valve and provided with a conduit opening laterally to the outside through a dispensing orifice, the head being actuatable by pressure by compressing a valve spring. Such a dispensing head is known from document FR-A-1572537.

Des têtes de distribution de ce type sont utilisées depuis longtemps pour la distribution de produit liquide sous forme d'aérosol. Elles ont été ensuite également utilisées pour la distribution de produit semi-liquide, visqueux ou pâteux, tel que des crèmes alimentaires ou cosmétiques. Or il n'est pas possible d'empêcher qu'une certaine quantité de produit reste dans le conduit de la tête de distribution après fermeture de la valve. Ce produit restant dans le conduit de distribution a tendance à s'écouler hors de l'orifice de distribution sur la tête et l'enceinte ou à goutter provocant des salissures et des tâches.Dispensing heads of this type have long been used for dispensing liquid product in aerosol form. They were then also used for the distribution of semi-liquid, viscous or pasty product, such as food or cosmetic creams. However, it is not possible to prevent a certain quantity of product remaining in the conduit of the dispensing head after closing the valve. This product remaining in the dispensing duct tends to flow out of the dispensing orifice on the head and the enclosure or to drip causing stains and stains.

La présente invention a pour but de remédier à cet inconvénient, c'est-à-dire de supprimer l'écoulement et les gouttes après utilisation de l'enceinte.The object of the present invention is to remedy this drawback, that is to say to eliminate the flow and the drops after use of the enclosure.

A cet effet la tête de distribution selon l'invention comprend une lame flexible solidaire de la coiffe, ladite lame s'appuyant sous tension contre l'extrémité du bec de distribution et obturant l'orifice de distribution en position de repos, une pression sur la coiffe ayant tout d'abord pour effet d'écarter la lame flexible de l'orifice de distribution.To this end, the dispensing head according to the invention comprises a flexible blade secured to the cap, said blade pressing under tension against the end of the dispensing spout and closing the dispensing orifice in the rest position, a pressure on the cap having first of all the effect of spreading the flexible blade of the dispensing orifice.

Lorsqu'on relâche la pression sur la coiffe, la valve se ferme, puis la lame flexible vient obturer l'orifice de distribution en empêchant ainsi le produit contenu dans le conduit de distribution de la tête de sortir par cet orifice. La fermeture de l'orifice de distribution en période de non-utilisation du produit a en outre pour effet d'isoler le produit contenu dans le conduit de distribution de la tête de l'extérieur, c'est-à-dire d'empêcher la souillure du produit contenu dans ce conduit par des poussières extérieures. Le produit situé près de l'orifice de distribution est par conséquent utilisable, ce qui n'est pas toujours le cas dans les têtes de distribution connues.When the pressure on the cap is released, the valve closes, then the flexible blade closes the dispensing orifice, thus preventing the product contained in the dispensing duct of the head from exiting through this orifice. Closing the dispensing orifice during periods of non-use of the product also has the effect of isolating the product contained in the dispensing duct from the head from the outside, that is to say preventing the contamination of the product contained in this conduit by external dust. The product located near the dispensing orifice is therefore usable, which is not always the case in known dispensing heads.

La lame flexible peut être venue d'une pièce avec la coiffe en matière synthétique ou être rapportée en métal, en matière synthétique ou autres matériaux. Elle s'applique de préférence sous tension contre l'orifice de distribution, de manière à bien obturer celui-ci.The flexible blade may have come in one piece with the synthetic material cover or be added in metal, synthetic material or other materials. It is preferably applied under tension against the dispensing orifice, so as to close it off.

La tête 1, en matière synthétique, présente une tige verticale 2 solidaire d'un clapet de valve 3 monté dans un corps de valve cylindrique 4, également en matière synthétique dont le siège est muni d'une garniture 5 en matière synthétique compressible. Le clapet 3 est maintenu en appui contre la garniture 5 par un ressort 6. Le corps de valve 4 a été représenté ici schématiquement. Il peut avoir diverses formes connues permettant de le fixer sur l'orifice d'une enceinte, de manière connue, au moyen d'une coupelle métallique. La base du corps de valve 4 est munie d'un orifice d'entrée 7 destiné à communiquer avec l'enceinte. La tête 1 est munie d'un bec latéral de distribution 8 en forme de bec de canard et traversé par un conduit de distribution 9 légèrement conique communiquant avec un conduit de distribution 10 traversant la tête 1 et débouchant latéralement à la hauteur de la garniture 5 de la valve.The head 1, made of synthetic material, has a vertical rod 2 secured to a valve valve 3 mounted in a cylindrical valve body 4, also made of synthetic material, the seat of which is provided with a lining 5 made of compressible synthetic material. The valve 3 is held in abutment against the lining 5 by a spring 6. The valve body 4 has been shown here diagrammatically. It can have various known shapes making it possible to fix it to the orifice of an enclosure, in a known manner, by means of a metal cup. The base of the valve body 4 is provided with an inlet orifice 7 intended to communicate with the enclosure. The head 1 is provided with a lateral dispensing spout 8 in the shape of a duckbill and crossed by a dispensing duct 9 slightly conical communicating with a dispensing duct 10 passing through the head 1 and emerging laterally at the level of the lining 5 of the valve.

Sur et autour de la tête est montée une coiffe cylindrique 11 en matière synthétique. Cette coiffe 11 est maintenue écartée de la tête 1 par un ressort 12 travaillant en compression entre la tête et la coiffe et de force sensiblement inférieure à celle du ressort de valve 6. La coiffe 11 présente un dégagement latéral rectangulaire 13 pour le bec de distribution 8. En dessous du bec de distribution 8, la tête présente une portée oblique 14 sensiblement parallèle à la face inférieure plane oblique 15 du bec 8. L'extrémité de cette portée 14 présente un rebord 16 soutenant une lame flexible en acier 17. Cette lame 17 est coudée et elle est fixée par serrage dans une gorge 18 de la coiffe 11. Le serrage est obtenu par la flexion du bord coudé 19 de la base de la lame. L'extrémité libre de la lame flexible 17 présente une extrémité coudée 20 s'appuyant sous tension contre l'extrémité du bec de distribution 8 et obturant l'orifice de ce bec. Le bord supérieur de cette partie coudée 20 est recourbée et vient en appui contre une portée 22 (figure 4) du bec de distribution 8 sous l'effet du ressort 12.On and around the head is mounted a cylindrical cap 11 made of synthetic material. This cap 11 is kept spaced from the head 1 by a spring 12 working in compression between the head and the cap and with a force substantially less than that of the valve spring 6. The cap 11 has a rectangular lateral clearance 13 for the dispensing spout 8. Below the dispensing spout 8, the head has an oblique bearing 14 substantially parallel to the face lower oblique plane 15 of the spout 8. The end of this seat 14 has a flange 16 supporting a flexible steel blade 17. This blade 17 is bent and it is fixed by clamping in a groove 18 of the cap 11. The clamping is obtained by bending the bent edge 19 of the base of the blade. The free end of the flexible blade 17 has a bent end 20 pressing under tension against the end of the dispensing spout 8 and closing the orifice of this spout. The upper edge of this bent part 20 is curved and bears against a bearing surface 22 (FIG. 4) of the dispensing spout 8 under the effect of the spring 12.

Le fonctionnement de la tête sera décrit au moyen des figures 4 et 5.The operation of the head will be described by means of Figures 4 and 5.

Lorsqu'on exerce une pression sur la coiffe 11, comme indiqué par la flèche à la figure 4, on comprime tout d'abord le ressort 12, sensiblement moins fort que le ressort de valve 6. Ceci a pour effet de produire un déplacement de la coiffe 11 relativement à la tête 1. La lame flexible 17 est entraînée par la coiffe 11 dans son déplacement, de telle sorte que la partie 20 de cette lame s'écarte de l'extrémité du bec 8, libérant ainsi l'orifice de distribution. La partie 20 de la lame étant sous tension, son extrémité vient s'appuyer contre la face inférieure oblique 15 du bec 8.When pressure is applied to the cover 11, as indicated by the arrow in FIG. 4, the spring 12 is first compressed, substantially weaker than the valve spring 6. This has the effect of producing a displacement of the cap 11 relative to the head 1. The flexible blade 17 is driven by the cap 11 in its movement, so that the part 20 of this blade moves away from the end of the spout 8, thus freeing the orifice of distribution. The part 20 of the blade being under tension, its end comes to bear against the oblique underside 15 of the spout 8.

Si l'on continue de presser sur la coiffe 11, celle-ci entraîne la tête 1 par le bord 23 de son dégagement latéral, comprimant ainsi le ressort de valve 6 et écartant le clapet de valve 3 de la garniture 5, de telle sorte que le produit à distribuer peut s'écouler par le conduit 10 et le conduit 9 du bec 8.If one continues to press on the cover 11, it drives the head 1 by the edge 23 of its lateral release, thus compressing the valve spring 6 and spreading the valve valve 3 from the packing 5, so that the product to be dispensed can flow through the conduit 10 and the conduit 9 of the spout 8.

Lorsqu'on relâche la pression sur la coiffe 11, le ressort de valve 6 sensiblement plus fort que le ressort 12, ferme d'abord la valve et l'on se retrouve dans la position représentée à la figure 4. En relâchant complètement la pression sur la coiffe 11, le ressort 12 soulève la coiffe 11 relativement à la tête 1 et l'extrémité 21 de la lame flexible 17, poussée par le rebord 16 de la portée 14 glisse sur la face intérieure oblique 15 du bec 8 et sur l'extrémité arrondie de cette face 15 en fléchissant, pour venir glisser sur l'orifice de distribution du bec 8 et obturer celui-ci comme représenté à la figure 1.When the pressure is released on the cover 11, the valve spring 6 substantially stronger than the spring 12, first closes the valve and we find ourselves in the position shown in FIG. 4. By completely releasing the pressure on the cap 11, the spring 12 lifts the cap 11 relative to the head 1 and the end 21 of the flexible blade 17, pushed by the rim 16 of the bearing surface 14 slides on the oblique inner face 15 of the spout 8 and on the the rounded end of this face 15, bending, so as to slide over the dispensing orifice of the spout 8 and seal it as shown in FIG. 1.

L'invention n'est pas limitée à la forme décrite, mais elle est au contraire susceptible de nombreuses variantes d'exécution. En particulier, la portée 14 pourrait être supprimée en utilisant une lame flexible 17 plus forte. Cette lame pourrait être simplement fixée par encastrement de l'extrémité de sa partie oblique dans la coiffe 11.The invention is not limited to the form described, but on the contrary is capable of numerous variant embodiments. In particular, the scope 14 could be eliminated by using a stronger flexible blade 17. This blade could simply be fixed by embedding the end of its oblique part in the cap 11.

La lame flexible pourrait être en un autre matériau que du métal, par exemple en matière synthétique, en fibre de verre ou de carbone, etc.The flexible blade could be made of a material other than metal, for example synthetic material, fiberglass or carbon, etc.

La lame flexible pourrait être venue d'une pièce de fabrication avec la coiffe 11. En d'autre terme la portée 14 pourrait constituer la lame flexible et présenter à cet effet une extrémité coudée verticale venant obturer l'orifice du bec 8.The flexible blade could have come from a production part with the cap 11. In other words the bearing surface 14 could constitute the flexible blade and present for this purpose a vertical bent end closing the orifice of the spout 8.

En réalisant l'orifice du bec 8 avec précision ou en le munissant d'une garniture il est possible d'obtenir une fermeture quasi étanche de l'orifice de distribution.By making the orifice of the spout 8 with precision or by providing it with a gasket, it is possible to obtain an almost sealed closure of the dispensing orifice.

La tête de distribution ne doit pas nécessairement être munie d'un bec faisant saillie hors de la coiffe. Dans le cas ou la tête ne serait pas pourvue d'un tel bec, la lame flexible d'obturation pourrait être montée à l'intérieur de la coiffe, entre celle-ci et la tête.The dispensing head does not necessarily have to have a spout protruding from the cap. In the case where the head is not provided with such a spout, the flexible shutter blade could be mounted inside the cap, between the latter and the head.
