The invention is characterised in that the elastic means (36) consists of a series of at least three flexible lugs (38) which are regularly angularly distributed and project from a cylindrical body (40) of the valve (34), said lugs being supported against a wall of the base (16).

Description

"Bouchon anti-goutte comportant un moyen élastique intégré à une soupape" "Drip stopper comprising an elastic means integrated with a valve"
L'invention concerne un bouchon dit "anti-goutte" pour un flacon déformable. L'invention concerne plus particulièrement un bouchon ditThe invention relates to a plug called "anti-drop" for a deformable bottle. The invention more particularly relates to a said plug
"anti-goutte" pour un flacon déformable contenant un produit cosmétique, pharmaceutique, industriel ou alimentaire sous forme liquide ou crémeuse, comportant :"anti-gout" for a deformable bottle containing a cosmetic, pharmaceutical, industrial or food product in liquid or creamy form, comprising:
- une embase sensiblement tubulaire, qui est destinée à être fixée de manière étanche sur un col tubulaire complémentaire du flacon, et dont une face transversale dite "inférieure" comporte au moins un orifice d'entrée communiquant avec le col du flacon,a substantially tubular base, which is intended to be fixed in a sealed manner on a complementary tubular neck of the bottle, and whose so-called "bottom" transverse face comprises at least one inlet orifice communicating with the neck of the bottle,
- un capuchon sensiblement tubulaire, qui est reçu sur l'embase, et dont une face transversale dite "supérieure" comporte au moins un orifice de sortie du produit, le capuchon et l'embase déterminant de manière étanche une chambre de passage du produit, interposée entre l'orifice d'entrée de l'embase et l'orifice de sortie du produit, une soupape d'obturation, coaxiale à l'orifice de sortie, étant montée coulissante dans la chambre de passage entre une position de fermeture dans laquelle elle obture l'orifice de sortie du produit et une position d'ouverture dans laquelle elle est agencée en retrait de l'orifice de sortie du produit pour en permettre le passage, et la soupape d'obturation étant rappelée élastiquement dans la chambre de passage par l'interméd iaire d'un moyen élastique à rencontre de l'orifice de sortie du produit, pour permettre le déplacement de la soupape d'obturation de sa position de fermeture à sa position d'ouverture sous la pression du produ it lorsqu'une pression est exercée sur le flacon souple, et le rappel de la soupape d'obturation de sa position d'ouverture à sa position de fermeture lorsque la pression est relâchée sur le flacon souple. On connaît de nombreux exemples de bouchons de ce type.a substantially tubular cap, which is received on the base, and a so-called "upper" transverse face has at least one outlet of the product, the cap and the base sealingly determining a passage chamber of the product, interposed between the inlet of the base and the outlet of the product, a shut-off valve, coaxial with the outlet orifice, being slidably mounted in the passage chamber between a closed position in which it closes the outlet of the product and an open position in which it is arranged back from the outlet of the product to allow passage, and the shutter valve being resiliently biased into the passage chamber by means of elastic means against the outlet of the product, to allow the shutter valve to move from its closed position to its open position under the pressure of the product. when a pressure is exerted on the flexible bottle, and the return of the shut-off valve from its open position to its closed position when the pressure is released on the flexible bottle. Numerous examples of plugs of this type are known.
Conventionnellement, le moyen élastique qui est destiné à permettre le rappel de la soupape d'obturation est constitué d'une membrane rapportée souple, perforée pour permettre le passage du produ it l iqu ide ou crémeux, ou bien est constitué d'un ressort de rappel hél icoïdal métall ique qui est interposé entre l'embase et la soupape.Conventionally, the resilient means which is intended to allow the return of the shut-off valve consists of a flexible membrane insert, perforated to allow the passage of the liquid or creamy product, or consists of a spring of helicoidal metallic return which is interposed between the base and the valve.
La membrane rapportée souple ou le ressort de rappel métall ique constituent donc des éléments rapportés qui augmentent la complexité du montage d'un bouchon anti-goutte conventionnel .The flexible diaphragm or the metal return spring therefore constitute add-on elements that increase the complexity of mounting a conventional anti-drip plug.
En particul ier, ces éléments rapportés étant destinés à coopérer avec la soupape, il est nécessaire de prévoir des moyens de centrage de la membrane rapportée ou du ressort rapporté par rapport à la soupape, et des moyens de centrage de la membrane rapportée ou du ressort rapporté au moins par rapport à l'embase.In particular, these inserts being intended to cooperate with the valve, it is necessary to provide means for centering the attached diaphragm or spring relative to the valve, and centering means of the attached diaphragm or spring reported at least relative to the base.
D'autre part, l'util isation d'une membrane rapportée ou d'un ressort rapporté dans un tel bouchon anti-goutte grèvent considérablement les coûts de revient d'un tel bouchon .On the other hand, the use of an attached membrane or a spring reported in such an anti-drop cap considerably increase the cost of such a plug.
L'invention remédie à cet inconvénient en proposant un bouchon anti-goutte comportant un moyen de rappel élastique intégré à la soupape. Dans ce but, l'invention propose un bouchon anti-goutte du type décrit précédemment, caractérisé en ce que le moyen élastique est constitué d'une série d'au moins trois pattes flexibles réparties angulairement de man ière régulière et venues de matière à partir d'un corps cyl indrique de la soupape, et qu i sont destinées à prendre appui contre une paroi de l'embase, pour assurer le rappel élastique de la soupape.The invention overcomes this disadvantage by proposing an anti-drop plug comprising an elastic return means integrated with the valve. For this purpose, the invention proposes an anti-drop plug of the type described above, characterized in that the elastic means consists of a series of at least three flexible tabs distributed angularly in a regular manner and coming from material from a cylindrical body of the valve, and that i i are intended to bear against a wall of the base, to ensure the elastic return of the valve.

On a représenté sur les figures des prem ier, deuxième, troisième et quatrième modes de réal isation d'un bouchon 10 d it "anti-goutte" .The figures of the first, second, third and fourth embodiments of a "drip-free" stopper 10 are shown in the figures.
De man ière connue, le bouchon 10 est destiné à équ iper un flacon déformable 12 d'un produ it cosmétique, pharmaceutique, industriel ou al imentaire, sous forme l iquide ou crémeuse. II sera donc compris que le champ d'appl ication du bouchon 10 trouve à s'appl iquer à des domaines très variés.In a known manner, the cap 10 is intended to equ iper a deformable bottle 12 of a cosmetic, pharmaceutical, industrial or food, in liquid or creamy form. It will therefore be understood that the field of application of the plug 10 is applicable to a wide variety of fields.
Le flacon 1 2 déformable peut notamment être un flacon rig ide dont une paroi est mobile. Ce type de flacon est largement connu de l'état de la techn ique et est par exemple util isé pour conten ir des pâtes dentifrices.The deformable flask 1 2 can in particular be a rigid bottle with a movable wall. This type of bottle is widely known from the state of the art and is for example used to contain toothpastes.
Dans un tel flacon, le volume du flacon varie au fur et à mesure de son util isation, car le déplacement de la paroi mobile accompagnant l'évacuation du produit. Le volume est du flacon est dans ce cas toujours intégralement rempli de produit.In such a bottle, the volume of the bottle varies as it is used, because the displacement of the mobile wall accompanying the evacuation of the product. The volume of the bottle is in this case always completely filled with product.
Le flacon 12 peut aussi être un flacon souple qui est destiné à être pressé pour provoquer l'évacuation du produit. Dans un tel flacon, le volume du flacon est globalement invariant, le produit qui est évacué hors du flacon étant remplacé par de l'air lorsque la pression exercée sur le flacon est relâchée.The bottle 12 may also be a flexible bottle which is intended to be pressed to cause the evacuation of the product. In such a bottle, the volume of the bottle is generally invariant, the product which is discharged from the bottle is replaced by air when the pressure exerted on the bottle is released.
Dans la suite de la présente description, on explicitera l'invention en référence à un flacon souple, mais il sera compris que cette disposition ne saurait être limitative de l'invention.In the remainder of the present description, the invention will be explained with reference to a flexible bottle, but it will be understood that this provision can not be limiting of the invention.
Le flacon 12 comporte un col 14. De manière connue, le bouchon 10 comporte une embase 16 sensiblement tubulaire, qui est destinée à être fixée de manière étanche, sur le col tubulaire 14 complémentaire du flacon 12. Par exemple, et de manière non limitative de l'invention, le col 14 du flacon 12 comporte des filets 18 qui sont destinés à recevoir un taraudage interne complémentaire 20 de l'embase 16.The bottle 12 has a neck 14. In known manner, the cap 10 comprises a substantially tubular base 16, which is intended to be sealed, on the tubular neck 14 complementary to the bottle 12. For example, and in a nonlimiting manner of the invention, the neck 14 of the bottle 12 comprises threads 18 which are intended to receive a complementary internal thread 20 of the base 16.
Bien entendu, en variante, l'embase 16 pourrait être emboîtée ou encliquetée sur le col d'un flacon 16 dépourvu de filets.Of course, alternatively, the base 16 could be nested or snapped onto the neck of a vial 16 without threads.
Une face transversale 22 dite "inférieure" de l'embase 16 comporte au moins un orifice d'entrée 24 communiquant avec le col 14 du flacon 12.A so-called "bottom" transverse face 22 of the base 16 comprises at least one inlet orifice 24 communicating with the neck 14 of the bottle 12.
De manière connue, le bouchon 10 comporte aussi un capuchon 26 sensiblement tubulaire, qui est reçu sur l'embase 16, et dont une face transversale 28 dite "supérieure" comporte au moins un orifice 30 de sortie du produit.In known manner, the cap 10 also comprises a substantially tubular cap 26, which is received on the base 16, and a so-called "upper" transverse face 28 has at least one outlet 30 of the product.
Par ailleurs, le capuchon 26 et l'embase 16 déterminent de manière étanche une chambre 32 de passage du produit, interposée entre l'orifice d'entrée 24 de l'embase 16 et l'orifice 30 de sortie du produit.Furthermore, the cap 26 and the base 16 seal a chamber 32 for passing the product, interposed between the inlet port 24 of the base 16 and the outlet port 30 of the product.
De manière connue, une soupape d'obturation 34, coaxiale à l'orifice de sortie 30, est montée coulissante dans la chambre de passage 32 entre une position de fermeture, représentée aux figures 3, 7, 10 et 15 dans laquelle elle obture l'orifice 30 de sortie du produit du capuchon 26 et une position d'ouverture, représentée aux figures 4, 8, 1 1 et 16 dans laquelle elle est agencée en retrait de l'orifice 30 de sortie du produit pour en permettre le passage.In known manner, a shut-off valve 34, coaxial with the outlet orifice 30, is slidably mounted in the chamber passage 32 between a closed position, shown in Figures 3, 7, 10 and 15 in which it closes the outlet port 30 of the product of the cap 26 and an open position, shown in Figures 4, 8, 1 1 and 16 wherein it is arranged recessed from the outlet port 30 of the product to allow passage therethrough.
Cette soupape 34 est rappelée élastiquement dans la chambre 32 de passage par l'intermédiaire d'un moyen élastique 36 à rencontre de l'orifice 30 de sortie du produit, pour permettre le déplacement de la soupape 34 d'obturation de sa position de fermeture à sa position d'ouverture sous la pression du produit lorsqu'une pression est exercée sur le flacon souple 12, et le rappel de la soupape 34 d'obturation de sa position d'ouverture à sa position de fermeture lorsque la pression est relâchée sur le flacon souple 12.This valve 34 is resiliently urged into the passage chamber 32 via an elastic means 36 against the outlet orifice 30 of the product, to enable the valve 34 to be displaced from its closed position. at its open position under the pressure of the product when pressure is exerted on the flexible bottle 12, and the return of the valve 34 shutter from its open position to its closed position when the pressure is released on the flexible bottle 12.
Conformément à l'invention, le moyen élastique 36 est constitué d'une série d'au moins trois pattes flexibles 38 réparties angulairement de manière régulière et venues de matière à partir d'un corps cylindrique 40 de la soupape 34, et qui sont destinées à prendre appui contre une paroi 42 de l'embase 16, pour assurer le rappel élastique de la soupape 34.According to the invention, the resilient means 36 consists of a series of at least three flexible tabs 38 angularly distributed regularly and integrally from a cylindrical body 40 of the valve 34, and which are intended to bear against a wall 42 of the base 16, to ensure the elastic return of the valve 34.
Dans les trois modes de réalisation préférés de l'invention, comme l'illustrent notamment les figures 1 et 5, les pattes flexibles 38 sont enroulées en hélice autour de l'axe de la soupape. Cette configuration permet de proposer une flexibilité maximale des pattes 38 tout en réduisant l'encombrement.In the three preferred embodiments of the invention, as illustrated in particular in Figures 1 and 5, the flexible tabs 38 are helically wound around the axis of the valve. This configuration makes it possible to provide maximum flexibility of the tabs 38 while reducing the bulk.
Dans les premier et deuxièmes modes de réalisation de l'invention, l'embase 16 comporte un conduit 44 dit "d'entrée", coaxial au col 14 du flacon 12 associé, au corps cylindrique 40 de la soupape 34 et à l'orifice 30 de sortie, qui communique avec l'orifice d'entrée 24, et dont la paroi 42 reçoit les pattes flexibles 38 du moyen élastique 36. Dans un premier mode de réalisation qui a été représenté aux figures 1 à 4 et plus particulièrement à la figure 1 , la soupape 34 est venue de matière avec l'embase 16, chaque patte flexible 38 du moyen élastique 36 comportant une extrémité supérieure 46 reliée à la soupape 34 et une extrémité inférieure 48 reliée à un bord intérieur de la paroi 42 du conduit d'entrée 44.In the first and second embodiments of the invention, the base 16 comprises a conduit 44 called "inlet", coaxial with the neck 14 of the associated bottle 12, the cylindrical body 40 of the valve 34 and the orifice 30, which communicates with the inlet orifice 24, and whose wall 42 receives the flexible tabs 38 of the elastic means 36. In a first embodiment which has been shown in FIGS. 1 to 4 and more particularly in FIG. 1, the valve 34 is integral with the base 16, each flexible tab 38 of the elastic means 36 having an upper end 46 connected to it. at the valve 34 and a lower end 48 connected to an inner edge of the wall 42 of the inlet duct 44.
En variante, dans un second mode de réalisation de l'invention qui a été représenté aux figures 5 à 8 et plus particulièrement à la figure 5, la soupape 34 est indépendante de l'embase 16, chaque patte flexible 38 comportant une extrémité supérieure 46 reliée à la soupape 34 et une extrémité inférieure 48 reliée à un anneau d'appui 50 qui est destiné à prendre appui contre une face transversale d'épaulement 52 faisant saillie à partir d'un bord intérieur de la paroi 42 du conduit d'entrée 44. Dans chacun de ces deux modes de réalisation de l'invention, on remarquera que la soupape 34 comporte une portée tronconique inférieure 54, tournée vers l'orifice d'entrée 24, qui est destinée à faciliter le passage du produit.Alternatively, in a second embodiment of the invention which has been shown in Figures 5 to 8 and more particularly in Figure 5, the valve 34 is independent of the base 16, each flexible tab 38 having an upper end 46 connected to the valve 34 and a lower end 48 connected to a support ring 50 which is intended to bear against a shoulder transverse face 52 projecting from an inner edge of the wall 42 of the inlet duct 44. In each of these two embodiments of the invention, it will be noted that the valve 34 comprises a lower frustoconical bearing surface 54, facing the inlet orifice 24, which is intended to facilitate the passage of the product.
On remarquera que, notamment dans ces deux modes de réalisation la soupape 34 présente dans sa partie supérieure correspondant à la portée tronconique 54 une surface projetée supérieure à celle de sa partie inférieure située sous les pattes 38, de sorte que toute pression sur le flacon soumet la soupape 34 à une pression pus grande sur sa partie supérieure que sur sa partie inférieure, ce qui provoque son déplacement de bas en haut. Cette disposition constructive faisant partie du dimensionnement de la soupape et étant largement connu de l'état de la technique, elle ne fera donc pas l'objet d'une plus ample description. Dans le prem ier mode de réal isation, l'orifice d'entrée 24 est simplement dél imité par le condu it 44.It will be noted that, in particular in these two embodiments, the valve 34 has in its upper part corresponding to the frustoconical bearing surface 54 a projecting surface greater than that of its lower part situated under the tabs 38, so that any pressure on the bottle submits the valve 34 at a higher pressure on its upper part than on its lower part, causing its movement from bottom to top. This constructive arrangement being part of the sizing of the valve and being widely known in the state of the art, it will not be the subject of further description. In the first embodiment, the inlet orifice 24 is simply delimited by the pipe 44.
Dans le second mode de réal isation , comme l'illustre la figure 5, l'orifice d'entrée 24 est constitué d'au moins une lumière formée dans la face transversale d'épaulement 52. En particul ier, la face transversale 52 peut comporter deux orifices d'entrées 24 présentant la forme de lunules.In the second embodiment, as illustrated in FIG. 5, the inlet orifice 24 consists of at least one light formed in the shoulder transverse face 52. In particular, the transverse face 52 may comprise two inlet orifices 24 having the shape of lunules.
Dans les troisième et quatrième modes de réal isation de l'invention qu i ont été représenté aux figures 9 à 1 1 et 14 à 1 6, l'embase 1 6 comporte de man ière analogue un condu it 44 d it "d'entrée" coaxial au col 14 du flacon 1 2, au corps cyl indrique 40 de la soupape 34 et à l'orifice 30 de sortie, qu i communique avec l'orifice d'entrée 24. La soupape 34 comporte de man ière analogue aux modes de réal isation précédent des pattes flexibles 38 dont les extrém ités 46 supérieures sont venues de matière avec le corps cylindrique 40 de la soupape 34.In the third and fourth embodiments of the invention, which have been shown in FIGS. 9 to 11 and 14 to 16, the base 1 6 comprises, in a similar way, an inlet channel 44. Coaxial with the neck 14 of the bottle 1 2, with the cylindrical body 40 of the valve 34 and with the outlet orifice 30, which communicates with the inlet orifice 24. The valve 34 comprises in a similar way to the modes Previous embodiment of the flexible tabs 38 whose upper ends 46 are integral with the cylindrical body 40 of the valve 34.
Le conduit 44 d'entrée reçoit coaxialement un boîtier tubulaire 47 de gu idage en coul issement de la soupape cylindrique 34 contre une paroi inférieure de fond 42 duquel les extrém ités inférieures 48 des pattes flexibles 38 de la soupape 34 prennent appu i .The inlet duct 44 coaxially receives a tubular casing 47 for guiding the cylindrical valve 34 against a lower bottom wall 42 from which the lower ends 48 of the flexible tabs 38 of the valve 34 take advantage.
Le corps de la soupape pourrait être sensiblement tubulaire et coul isser à l'extérieur du boîtier tubulaire 47. Toutefois, pour des raisons de compacité, la soupape 34 coul isse de préférence à l'intérieur du boîtier 47.The body of the valve could be substantially tubular and cast out of the tubular casing 47. However, for reasons of compactness, the valve 34 is preferably cast inside the casing 47.
Il sera donc compris que, dans le mode de réal isation préféré de l'invention , le boîtier 47 est obturé par la paroi inférieure de fond 42 et que la soupape est susceptible de faire saill ie hors du boîtier 47 un iquement par une ouverture supérieure 51 du boîtier 47. Cette configuration permet de garantir que le produ it l iqu ide ou crémeux ne soll icite que la partie supérieure de la soupape 34 lorsqu'une pression est exercée sur le flacon 1 2, pour en provoquer l'ouverture.It will therefore be understood that, in the preferred embodiment of the invention, the housing 47 is closed off by the bottom bottom wall 42 and the valve is able to protrude outside the housing 47 only through an upper opening. 51 of the casing 47. This configuration ensures that the liquiqu ic or creamy product solicits only the upper part of the valve 34 when a pressure is exerted on the bottle 1 2, to cause opening.
Il sera aussi compris que, de préférence, le boîtier 47 est venu de matière avec l'embase 1 6. Par ailleurs, la soupape 34 comporte une portée troncon ique supérieure 56 qui est destinée à coopérer avec un siège troncon ique 58 agencé autour d'un perçage du capuchon 26 formant l'orifice 30 de sortie, ladite portée tronconique 56 étant surmontée d'un téton 60 destiné à pénétrer dans ledit perçage 30, pour assurer une obturation étanche de l'orifice 30 de sortie du capuchon par la soupape 34.It will also be understood that, preferably, the housing 47 is integral with the base 1 6. Furthermore, the valve 34 has an upper frustoconical surface 56 which is intended to cooperate with a frustoconical seat 58 arranged around a bore of the cap 26 forming the outlet orifice 30, said frustoconical surface 56 being surmounted by a pin 60 for penetrating into said bore 30, to seal the outlet orifice 30 of the cap by the valve 34.
Par ailleurs, le bouchon 10 comporte avantageusement des moyens destinés à permettre sélectivement le passage du produit. A cet effet, comme l'illustrent les figures 2 à 4, et 6 à 1 1 , quel que soit le mode de réal isation de l'invention , le capuchon 26 est monté mobile coaxialement à l'embase 16 et il est susceptible d'être verrouillé :Furthermore, the cap 10 advantageously comprises means for selectively allowing the passage of the product. For this purpose, as illustrated in FIGS. 2 to 4 and 6 to 11, whatever the embodiment of the invention, the cap 26 is mounted to move coaxially with the base 16 and is capable of to be locked:
- dans une position basse, représenté aux figures 2, 6, 9 et 14 selon laquelle la d istance entre le capuchon 26 et I'embase1 6 est réduite de manière que les pattes 38 élastiques de la soupape 34 soient fortement soll icitées de man ière que la soupape 34 obture en permanence l'orifice 30 de sortie, ou bienin a low position, represented in FIGS. 2, 6, 9 and 14, according to which the distance between the cap 26 and the base 6 is reduced so that the elastic tabs of the valve 34 are strongly stressed so as to that the valve 34 permanently closes the outlet orifice 30, or
- dans une position haute, représentée aux figures 3, 4, 7, 8, 10, 1 1 , 1 5, 1 6 selon laquelle la distance entre le capuchon 26 et l'embase 16 est élevée de manière que les pattes élastiques 38 de la soupape soient faiblement soll icitées en permanence, de man ière que la soupape 34 n'obture l'orifice de sortie qu'en l'absence d'une pression de produ it liquide ou crémeux susceptible de soll iciter la soupape 34 vers sa position d'ouverture à rencontre de l'effort de rappel des pattes élastiques 38.in a raised position, represented in FIGS. 3, 4, 7, 8, 10, 1 1, 1 5, 1 6 according to which the distance between the cap 26 and the base 16 is raised so that the elastic tabs 38 of the valve are poorly solicited permanently, so that the valve 34 obturates the outlet orifice in the absence of a liquid or creamy production pressure may solicit the valve 34 to its position opening against the restoring force of the elastic tabs 38.
Pour permettre le mouvement du capuchon 26 par rapport à l'embase 16 et son verrouillage dans chacune de deux positions précitées, comme l'illustrent les figures 3, 4, 7, 8, 10, 1 1 , 1 5 et 1 6, le capuchon tubulaire 26 est d'un diamètre intérieur correspondant au diamètre extérieur de l'embase 1 6 et le capuchon 26 comporte au moins un doigt radial 62, s'étendant à partir d'un bord intérieur 64 de sa paroi tubulaire, qui est reçu dans une lumière hélicoïdale 66 formée sur un bord extérieur 68 de la paroi tubulaire de l'embase.To allow the movement of the cap 26 relative to the base 16 and its locking in each of two aforementioned positions, as illustrated in FIGS. 3, 4, 7, 8, 10, 11, 15 and 16, the tubular cap 26 is of an inner diameter corresponding to the outer diameter of the base 1 6 and the cap 26 has at least one radial finger 62, extending to from an inner edge 64 of its tubular wall, which is received in a helical slot 66 formed on an outer edge 68 of the tubular wall of the base.
Comme l'illustrent plus particulièrement les figures 1 et 5, la lumière 66 comportant à proximité de son extrémité 71 correspondant à la position basse du capuchon un ergot 70 qui s'étend vers l'intérieur de la lumière 66 et qui est destiné à permettre le verrouillage du doigt 62 à ladite extrémité 71 de la lumière 66, pour permettre le mouvement du capuchon 26 et son verrouillage dans sa position basse.As is illustrated more particularly in FIGS. 1 and 5, the light 66 comprising, close to its end 71 corresponding to the lower position of the cap, a lug 70 which extends towards the inside of the light 66 and which is intended to allow locking the finger 62 at said end 71 of the light 66, to allow the movement of the cap 26 and its locking in its low position.
Enfin on remarquera que le capuchon 26 comporte une portée tubulaire intérieure 72 d'un diamètre extérieur correspondant au diamètre intérieur du conduit d'entrée 44, pour assurer le guidage du capuchon 26 par rapport à l'embase 16 et pour délimiter la chambre 32 de passage du produit.Finally, it will be noted that the cap 26 has an inner tubular bearing surface 72 of an external diameter corresponding to the inside diameter of the inlet duct 44, in order to guide the cap 26 with respect to the base 16 and to delimit the chamber 32 of passage of the product.
Dans les premier et deuxième modes de réalisation de l'invention, la portée tubulaire intérieure 72 reçoit la soupape 34.In the first and second embodiments of the invention, the inner tubular bearing surface 72 receives the valve 34.
Une autre caractéristique particulièrement avantageuse de l'invention, qui concerne plus particulièrement le cas d'un flacon souple 12, est que le bouchon comporte des moyens de mise à l'air dudit flacon souple 12.Another particularly advantageous feature of the invention, which more particularly relates to the case of a flexible bottle 12, is that the cap comprises means for venting said flexible bottle 12.
Selon un mode de réalisation (non représenté), le bouchon 10 peut être constitué d'un bouchon 10 du type de celui décrit en référence aux premier, deuxième et troisième modes de réalisation de l'invention, à cette différence que les moyens de mise à l'air du flacon comportent un tarage déterminé des pattes flexibles 38 du moyen élastique 36. Ce tarage est destiné à permettre le maintien de la soupape 34 d'obturation dans sa position d'ouverture dès lors qu'une dépression d'air déterminée règne dans la flacon 12, et à permettre le rappel de la soupape 34 d'obturation dans sa position de fermeture dès lors que ladite dépression s'annule. Les moyens de mise à l'air du flacon souple peuvent constituer en des d ispositions mécan iques particul ières qu i ont été représentées en référence aux figures 1 2 à 1 6, lesquelles figures représentent un bouchon fonctionnant selon le même principe que le bouchon 10 décrit en référence aux figures 9 à 1 1 .According to one embodiment (not shown), the plug 10 may consist of a plug 10 of the type described with reference to the first, second and third embodiments of the invention, with the difference that the setting means in the air of the bottle comprise a determined setting flexible tabs 38 of the resilient means 36. This setting is intended to allow the maintenance of the valve 34 shutter in its open position whenever an air depression determined reign in the bottle 12, and to allow the return of the valve 34 shutter in its closed position as soon as said depression is canceled. The venting means of the flexible bottle may be in particular mechanical positions that have been shown with reference to FIGS. 1 2 to 1 6, which figures represent a stopper operating according to the same principle as the stopper 10. described with reference to Figures 9 to 1 1.
D'une man ière générale, les moyens de mise à l'air du flacon 12 comportent au moins un lamage 53 qui est formé sur le pourtour du perçage de l'orifice 30 du capuchon 26 et qui débouche dans le siège troncon ique 58. Ce lamage 53, qu i commun ique avec la chambre 32 de passage, forme un évent permettant la m ise à l'air du flacon 12.In a general manner, the means for venting the bottle 12 comprise at least one countersink 53 which is formed around the periphery of the hole 30 of the cap 26 and which opens into the frustoconical seat 58. This countersink 53, which i communicates with the passage chamber 32, forms a vent allowing the air to be vented from the bottle 12.
Cette configuration , qu i a été représentée aux figures 13 à 1 6, peut s'appl iquer aussi à tout bouchon 1 0 du type décrit précédemment en référence aux premier, deuxième et troisièmes modes de réal isation de l'invention .This configuration, which has been shown in FIGS. 13 to 16, may also apply to any plug 10 of the type described above with reference to the first, second and third embodiments of the invention.
L'arch itecture particul ière du bouchon 1 0 selon le troisième mode de réal isation de l'invention permet néanmoins de proposer un quatrième mode de réal isation permettant d'amél iorer la ventilation du flacon 12 et de permettre un passage d'air accru au travers du lamage 53.The particular architecture of the plug 1 0 according to the third embodiment of the invention nevertheless makes it possible to propose a fourth mode of real isation to improve the ventilation of the bottle 12 and allow an increased air passage through the countersink 53.
Dans cette configuration, qu i , pour mémoire, reprend la plupart des dispositions constructives du bouchon selon le troisième mode de réal isation de l'invention , les moyens de m ise à l'air du flacon 1 2 comportent au moins : - un moyen 55 d'indexation angulaire en rotation de la soupape 34 dans son boîtier tubulaire,In this configuration, which, for the sake of memory, incorporates most of the constructional arrangements of the plug according to the third embodiment of the invention, the means for airtightness of the bottle 1 2 comprise at least: 55 angular indexing in rotation of the valve 34 in its tubular housing,
- au moins une prem ier bossage 57 d'orientation verticale, porté par une paroi transversale 49 d ite "supérieure" du capuchon 26 qu i est susceptible, lorsque que la capuchon 12 occupe sa position haute, de coopérer avec un second bossage 59 d'orientation verticale porté par une face supérieure 61 de la soupape 34 pour provoquer un déplacement déterm iné de la soupape 34 vers sa position d'ouverture de man ière à décoller la portée tronconique supérieure 56 du siège tronconique 58 afin de permettre la mise à l'air du flacon 12, comme représenté à la figure 15.at least one first boss 57 of vertical orientation, carried by a transverse wall 49 of "upper" of the cap 26 that is likely, when the cap 12 is in its upper position, to cooperate with a second boss 59 d vertical orientation carried by an upper face 61 of the valve 34 to cause a determined displacement of the valve 34 to its open position so as to take off the frustoconical upper surface 56 of the frustoconical seat 58 to allow the venting of the bottle 12, as shown in Figure 15.
Dans le mode de réalisation préféré de l'invention, le passage du capuchon 26 de sa position basse à sa position haute correspond à une rotation de 90 degrés dudit capuchon 26 et le capuchon 26 comporte deux premiers bossages 57 disposés angulairement à 180 degrés l'un de l'autre. Cette configuration permet de monter le capuchon 26 sur l'embase 16 sans se préoccuper de l'orientation dudit capuchon 26, et de garantir que le second bossage 59 sera sollicité par un des premiers bossagesIn the preferred embodiment of the invention, the passage of the cap 26 from its low position to its high position corresponds to a 90-degree rotation of said cap 26 and the cap 26 has two first bosses 57 angularly disposed at 180 degrees. one of the other. This configuration makes it possible to mount the cap 26 on the base 16 without worrying about the orientation of said cap 26, and to guarantee that the second boss 59 will be urged by one of the first bosses
57.57.
Dans le mode de réalisation préféré de l'invention le moyen d'indexation angulaire en rotation de la soupape 34 dans son boîtier tubulaire comporte un profil carré 55, qui s'étend à partir de la paroi inférieure 42 de fond du boîtier 47, et qui est reçu dans une cavité complémentaire 65 formée dans le corps de la soupape 34. Cette disposition garantit la bonne orientation du second bossage 59 pour qu'il soit sollicité par un premier bossage 57 comme représenté à la figure 15.In the preferred embodiment of the invention the angular indexing means in rotation of the valve 34 in its tubular housing comprises a square profile 55, which extends from the bottom wall 42 of the bottom of the housing 47, and which is received in a complementary cavity 65 formed in the body of the valve 34. This arrangement ensures the proper orientation of the second boss 59 so that it is biased by a first boss 57 as shown in Figure 15.
Ainsi, dans la position basse du capuchon 26 représentée à la figure 14, aucun premier bossage 57 ne sollicite de second bossage 59. La soupape 34 est donc fermée.Thus, in the low position of the cap 26 shown in Figure 14, no first boss 57 solicits second boss 59. The valve 34 is closed.
Dès lors que le capuchon 26 est pivoté, un des premiers bossages 57 sollicite le second bossage 59, et la soupape 34 voit sa portée tronconique supérieure 56 décollée du siège tronconique 58 afin de permettre la mise à l'air du flacon 12, comme représenté aux figures 15 et 16.As soon as the cap 26 is pivoted, one of the first bosses 57 urges the second boss 59, and the valve 34 sees its frustoconical upper surface 56 detached from the frustoconical seat 58 to allow the venting of the bottle 12, as shown Figures 15 and 16.
La sortie du produit, représentée à la figure 16, s'effectue d'une manière analogue aux modes de réalisation précédents.The output of the product, shown in FIG. 16, is carried out in a manner similar to the preceding embodiments.
L'invention propose donc un bouchon 10 anti-goutte formé d'un nombre limité de pièces, et pouvant donc à ce titre être produit à un coût réduit en grande série. The invention thus proposes an anti-drop plug formed of a limited number of parts, and can therefore be produced at a reduced cost in large series.
