Description

"Bouchon anti-goutte à capuchon mobile rappelé élastiquement" "Anti-drip cap with mobile cap elastically recalled"
L'invention concerne un bouchon dit "anti-goutte" pour un flacon déformable. L'invention concerne plus particulièrement un bouchon pour un flacon déformable, notamment un flacon souple, contenant un produit cosmétique, pharmaceutique, industriel ou alimentaire sous forme liquide ou crémeuse, comportant :The invention relates to a plug called "anti-drop" for a deformable bottle. The invention relates more particularly to a plug for a deformable bottle, in particular a flexible 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 paroi transversale dite "supérieure" comporte au moins un orifice d'entrée communiquant avec le col du flacon,- A substantially tubular base, which is intended to be sealingly attached to a complementary tubular neck of the bottle, and a so-called "upper" transverse wall comprises at least one inlet communicating with the neck of the bottle,
- un capuchon sensiblement tubulaire, qui coiffe de manière étanche l'embase, et dont une paroi 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, le capuchon étant mobile verticalement entre au moins :a substantially tubular cap, which covers the base in a sealed manner, and whose so-called "upper" transverse face wall has at least one outlet orifice of the product, the cap and the base sealingly determining a passage chamber of the product, interposed between the inlet port of the base and the outlet of the product, the cap being movable vertically between at least:
- une position basse d'obturation et de verrouillage dans laquelle le capuchon est bloqué sur l'embase et dans laquelle l'orifice de sortie du produit est descendu sur un élément d'obturation qui fait saillie coaxialement à l'embase à partir de sa paroi transversale supérieure, ledit élément d'obturation obturant l'orifice de sortie du produit,a low closing and locking position in which the cap is blocked on the base and in which the outlet of the product is lowered on a closure element which projects coaxially from the base from its base; upper transverse wall, said shutter member sealing the outlet of the product,
- une position haute de distribution dans laquelle l'orifice de sortie est agencé avec un jeu élevé déterminé au dessus de l'élément d'obturation pour permettre le passage du produit au travers des orifices d'entrée et de sortie et de la chambre de passage. On connaît de nombreux exemples de bouchons de ce type.a high dispensing position in which the outlet orifice is arranged with a high clearance determined above the closure element to allow the passage of the product through the inlet and outlet orifices and the chamber of passage. Numerous examples of plugs of this type are known.
Un tel bouchon est couramment utilisé dans l'industrie cosmétique ou alimentaire pour assurer la distribution d'un produit crémeux.Such a plug is commonly used in the cosmetic or food industry to ensure the distribution of a creamy product.
Un tel bouchon présente toutefois l'inconvénient de ne comporter qu'une position basse d'obturation ou une position haute de distribution .Such a plug, however, has the disadvantage of having only a low shutter position or a high dispensing position.
Ainsi un tel bouchon doit nécessiter une manipulation à chaque fois qu'il doit être utilisé afin de l'ouvrir, sous peine de voir le produit qu'il contient sécher et obturer l'orifice de sortie du produit.Thus such a cap must require manipulation every time it must be used in order to open it, otherwise the product it contains will dry and close the outlet of the product.
Par ailleurs, un tel bouchon ne peut demeurer en position haute de distribution sans risque d'être renversé et de voir ainsi le produit qu'il contient s'en écouler.Moreover, such a stopper can not remain in the upper dispensing position without risk of being knocked over and thus see the product it contains flow.
L'invention remédie à cet inconvénient en proposant un bouchon anti-goutte dont l'orifice de sortie du produit ne s'ouvre que lorsque le bouchon est alimenté en produit, par exemple lorsque l'on exerce une pression sur un flacon souple sur lequel est vissé le bouchon .The invention overcomes this disadvantage by proposing an anti-drop plug whose product outlet port opens only when the cap is supplied with product, for example when a pressure is exerted on a flexible bottle on which is screwed the cap.

• la position haute de distribution dans laquelle le capuchon est agencé selon le jeu élevé déterminé de l'embase pour permettre à l'orifice de sortie du produit, distant dudit jeu élevé de l'élément d'obturation, de permettre le passage du produit au travers des orifices d'entrée et de sortie et de la chambre de passage, un moyen de rappel élastique de raideur déterminée étant interposé dans la seconde position angulaire entre le capuchon et l'embase, pour permettre le rappel du capuchon vers sa position verticale intermédiaire et pour permettre la levée du capuchon vers sa position haute de distribution dès lors qu'une injection de produit provenant du col du flacon exerce sur la paroi supérieure de la chambre de passage une pression suffisante pour que l'effort résultant surmonte l'effort dudit moyen de rappel élastique.The dispensing high position in which the cap is arranged according to the determined high clearance of the base to allow the outlet of the product, remote from said high clearance of the closure member, to allow the passage of the product through the inlet and outlet orifices and the passage chamber, an elastic return means of determined stiffness being interposed in the second angular position between the cap and the base, to allow the cap to be returned to its upright position. intermediate and to allow the lifting of the cap to its upper dispensing position when an injection of product from the neck of the bottle exerts on the upper wall of the passage chamber sufficient pressure for the resulting effort to overcome the effort said elastic return means.

On a représenté sur les figures un bouchon 10 d it "anti- goutte" réalisé conformément à l'invention .There is shown in the figures a plug 10 d it "anti-drop" made according to the invention.
De man ière connue, le bouchon 10 est destiné à équ iper un flacon déformable 12 d'un produit cosmétique, pharmaceutique, industriel ou alimentaire, sous forme l iqu ide 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 plug 10 is intended to equ iper a deformable vial 12 of a cosmetic, pharmaceutical, industrial or food product, 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 produ it. Le volume est du flacon est dans ce cas toujours intégralement rempl i de produit. Le flacon 1 2 peut aussi être un flacon souple qu i est destiné à être pressé pour provoquer l'évacuation du produ it.In such a bottle, the volume of the bottle varies as it is used, since 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. The bottle 1 2 may also be a flexible bottle that is intended to be pressed to cause the evacuation of the product.
Dans un tel flacon, le volume du flacon est globalement invariant, le produ it qu i est évacué hors du flacon étant remplacé par de l'air lorsque la pression exercée sur le flacon est relâchée. Dans la su ite de la présente description , on expl icitera l'invention en référence à un flacon 1 2 souple, mais il sera compris que cette d isposition ne saurait être l imitative de l'invention .In such a bottle, the volume of the bottle is generally invariant, the product that is evacuated from the bottle being replaced by air when the pressure exerted on the bottle is released. In the context of the present description, the invention will be explained with reference to a flexible bottle, but it will be understood that this deposition can not be imitative of the invention.
Le flacon 12 comporte un col 14. De man ière connue, le bouchon 1 0 comporte une embase 16 sensiblement tubulaire, qu i est destinée à être fixée de man ière étanche, sur le col tubulaire 14 complémentaire du flacon 1 2. 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 comprises a neck 14. In a known manner, the stopper 10 comprises a substantially tubular base 16, which is intended to be fixed in a leaktight manner, on the complementary tubular neck 14 of the bottle 1 2. For example, and without limitation to 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.
Comme l'illustrent plus particulièrement les figures 1 et 3, une paroi transversale dite "supérieure" 22 l'embase comporte au moins un orifice 24 d'entrée qui est destiné à communiquer avec le col 14 du flacon 12.As is illustrated more particularly in FIGS. 1 and 3, a so-called "upper" transverse wall 22 of the base comprises at least one inlet orifice 24 which is intended to communicate with the neck 14 of the bottle 12.
L'embase 16 reçoit un capuchon 26 sensiblement tubulaire, qui coiffe de manière étanche l'embase 16, et dont une paroi face transversale 28 dite "supérieure" comporte au moins un orifice 30 de sortie du produit.The base 16 receives a substantially tubular cap 26, which sealingly covers the base 16, and a so-called "upper" transverse face wall 28 has at least one outlet 30 of the product.
Ainsi, comme l'illustrent les figures 4 à 6, 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.Thus, as illustrated in FIGS. 4 to 6, the cap 26 and the base 16 seal a chamber 32 for passing the product interposed between the inlet orifice 24 of the base 16 and the orifice 30 output of the product.
Dans le mode de réalisation préféré de l'invention, la paroi 22 supérieure de l'embase 16 comporte un puits tubulaire 17, qui s'étendant verticalement vers le col 14 du flacon 12, et au fond duquel est agencé l'orifice d'entrée 24. Ce puits 17 reçoit en coulissement une cheminée tubulaire 23 qui s'étend à partir de la paroi transversale 28 du capuchon 26, ladite cheminée comportant à son extrémité supérieure l'orifice de sortie 30.In the preferred embodiment of the invention, the upper wall 22 of the base 16 comprises a tubular well 17, which extends vertically towards the neck 14 of the bottle 12, and at the bottom of which is arranged the orifice of 24. This well 17 slidably receives a tubular chimney 23 which extends from the transverse wall 28 of the cap 26, said chimney having at its upper end the outlet orifice 30.
De la sorte le puits tubulaire 17 et la cheminée tubulaire 23 déterminent la chambre de passage 32 de manière parfaitement étanche.In this way the tubular well 17 and the tubular chimney 23 determine the passage chamber 32 in a perfectly sealed manner.
Il sera compris néanmoins que cette disposition n'est pas limitative de l'invention et que toute configuration permettant de déterminer une chambre de passage 32 entre l'embase 16 et le capuchon 26 peut convenir à la bonne mise en œuvre de l'invention .It will be understood however that this provision is not limiting of the invention and that any configuration for determining a passage chamber 32 between the base 16 and the cap 26 may be suitable for the proper implementation of the invention.
De manière connue, le capuchon 26 est mobile verticalement entre au moins une position basse d'obturation et de verrouillage, représentée à la figure 4, dans laquelle le capuchon 26 est bloqué sur l'embase 16 et dans laquelle l'orifice 30 de sortie du produit est descendu sur un élément d'obturation 34 qui fait saillie coaxialement à l'embase 16 à partir de sa paroi transversale 22 supérieure, ledit élément 34 d'obturation obturant l'orifice 30 de sortie du produit, et une position haute de distribution, représentée à la figure 6, dans laquelle l'orifice 30 de sortie est agencé avec un jeu "J" élevé déterminé au dessus de l'élément d'obturation 34 pour permettre le passage du produit au travers des orifices d'entrée 24 et de sortie 30 et de la chambre 32 de passage.In known manner, the cap 26 is vertically movable between at least one lower position of closure and locking, shown in Figure 4, in which the cap 26 is blocked on the base 16 and in which the outlet orifice 30 of the product is lowered on a closure member 34 which protrudes coaxially with the base 16 from its upper transverse wall 22, said element 34 shutter closing the outlet orifice 30 of the product, and a high dispensing position, shown in FIG. 6, in which the outlet orifice 30 is arranged with a high clearance "J" determined above the element shutter 34 to allow the passage of the product through the inlet ports 24 and outlet 30 and the passage chamber 32.
Un inconvénient connu d'un tel bouchon est qu'il ne peut demeurer en position haute de distribution sans risque d'être renversé et de voir ainsi le produit qu'il contient s'en écouler.A known disadvantage of such a plug is that it can not remain in the upper dispensing position without risk of being knocked over and thus see the product it contains flow.
L'invention remédie à cet inconvénient en proposant un bouchon anti-goutte dont l'orifice 30 de sortie du produit n'est découvert lorsque le bouchon 10 est alimenté en produit, par exemple lorsque l'on exerce une pression sur le flacon souple 12 sur lequel est vissé le bouchon 10.The invention overcomes this disadvantage by proposing an anti-drop plug whose outlet 30 of the product is not discovered when the cap 10 is supplied with product, for example when pressure is exerted on the flexible bottle 12 on which is screwed the plug 10.
Dans ce but, l'invention propose un bouchon 10 anti-goutte du type décrit précédemment, caractérisé en ce que le capuchon 26 est monté pivotant entre deux postions angulaires qui ont été représentées d'une part à la figure 4 et d'autre part aux figures 5 et 6.For this purpose, the invention proposes an anti-drop plug of the type described above, characterized in that the cap 26 is pivotally mounted between two angular positions which have been represented on the one hand in FIG. 4 and on the other hand in Figures 5 and 6.
Dans la première position angulaire de la figure 4, le capuchon 26 est bloqué en position basse d'obturation et de verrouillage par une butée supérieure 36 solidaire de l'embase 16,In the first angular position of FIG. 4, the cap 26 is blocked in the low position of closing and locking by an upper stop 36 secured to the base 16,
Dans la seconde position angulaire des figures 5 et 6, le capuchon 26 libéré de la butée 36 est mobile verticalement entre au moins une position intermédiaire, représentée à la figure 5 dans laquelle le capuchon 26 est agencé selon un jeu réduit "j" de l'embase 16 pour permettre à l'orifice 30 de sortie du produit, distant dudit jeu réduit de l'élément 34 d'obturation, de réaliser une mise à l'air du flacon associé, et la position haute de distribution de la figure 6 dans laquelle le capuchon est agencé selon le jeu "J" élevé déterminé de l'embase 16 pour permettre à l'orifice 30 de sortie du produit, distant dudit jeu "J" élevé de l'élément 34 d'obturation, de permettre le passage du produit au travers des orifices d'entrée 24 et de sortie 30 et de la chambre 32 de passage.In the second angular position of Figures 5 and 6, the cap 26 released from the stop 36 is vertically movable between at least one intermediate position, shown in Figure 5 in which the cap 26 is arranged in a reduced clearance "j" of the base 16 to allow the outlet port 30 of the product, remote said reduced set of the element 34 shutter, to achieve a venting of the associated bottle, and the upper dispensing position of FIG. 6 in which the cap is arranged according to the set "J" high set of the base 16 to allow the outlet port 30 of the product remote from said high clearance "J" of the closure element 34, allowing the product to pass through the inlet and outlet openings 24 and 30 and the passage chamber 32.
Comme l'illustre la figure 3, on remarquera qu'à cet effet, l'élément 34 d'obturation est sensiblement tronconique et coaxial à l'embase 16. L'embase 16 comporte au moins deux lumières 24 en forme de lunules réparties angulairement de manière régulière autour de l'élément 34 d'obturation, qui forment chacune un orifice d'entrée 24.As illustrated in FIG. 3, it will be noted that for this purpose, the closure element 34 is substantially frustoconical and coaxial with the base 16. The base 16 comprises at least two slots 24 in the shape of lunules distributed angularly. in a regular manner around the closure element 34, which each form an inlet orifice 24.
Un avantage particulièrement sensible de l'invention est que, dans la seconde position angulaire, le passage de la position intermédiaire de mise à l'air du flacon à la position haute de distribution du produit est assurée par la pression de ce même produit, tandis que le passage inverse de la position haute de distribution à la position intermédiaire de mise à l'air du flacon est assurée par un moyen de rappel élastique.A particularly significant advantage of the invention is that, in the second angular position, the passage of the intermediate position of venting the bottle to the upper dispensing position of the product is ensured by the pressure of the same product, while that the reverse passage from the high dispensing position to the intermediate position of venting the bottle is provided by an elastic return means.
Ainsi, comme l'illustrent les figures 1 et 2, un moyen élastique 38 de raideur déterminée est interposé dans la seconde position angulaire entre le capuchon 26 et l'embase 16.Thus, as illustrated in FIGS. 1 and 2, a resilient means 38 of determined stiffness is interposed in the second angular position between the cap 26 and the base 16.
Ce moyen élastique 38 permet le rappel du capuchon 26 vers sa position verticale intermédiaire de la figure 5.This elastic means 38 allows the cap 26 to return to its intermediate vertical position in FIG. 5.
Par ailleurs, la raideur déterminée du moyen élastique permet la levée du capuchon 26 vers sa position haute de distribution de la figure 6 dès lors qu'une injection de produit provenant du col du flacon, et donc pénétrant par l'orifice d'entrée 24 dans la chambre de passage 32 exerce sur la paroi supérieure 28 de la chambre de passage 32 une pression suffisante pour que l'effort résultant surmonte l'effort dudit moyen de rappel élastique 38 et soulève le capuchon 26, permettant ainsi à l'orifice 30 d'être agencé avec le jeu "J" de l'élément 34 d'obturation .Furthermore, the determined stiffness of the elastic means allows the cap 26 to be lifted to its upper dispensing position in FIG. 6 as soon as an injection of product originating from the neck of the bottle, and thus penetrating through the inlet orifice 24. in the passage chamber 32 exerts on the upper wall 28 of the passage chamber 32 a pressure sufficient for the resultant force to overcome the force of said elastic return means 38 and raises the cap 26, thus allowing the orifice 30 to be arranged with the clearance "J" of the element 34 shutter.
Pour parvenir à cette configuration, une portée tubulaire intérieure 40 du capuchon 26 comporte au moins un premier élément faisant saillie radialement vers l'intérieur du capuchonTo achieve this configuration, an inner tubular surface 40 of the cap 26 has at least one first element projecting radially inwardly of the cap.
26. Cet élément est destiné à coopérer avec une butée supérieure26. This element is intended to cooperate with a top stop
36 faisant saillie radialement à l'extérieur de l'embase.36 protruding radially outside the base.
Par ailleurs, comme l'illustre la figure 2, la portée tubulaire 40 intérieure du capuchon 26 comporte au moins un deuxième élément, faisant saillie radialement vers l'intérieur du capuchon 26, qui est destiné à coopérer avec une rampe 42 qui s'étend autour d'une extrémité inférieure 44 de l'embase 16 suivant un secteur "α" angulaire correspondant à l'angle formé entre les première et seconde positions angulaires, pour solliciter le capuchon 26 de sa position basse d'obturation et de verrouillage à sa position intermédiaire.Furthermore, as illustrated in FIG. 2, the inner tubular bearing surface 40 of the cap 26 comprises at least one second element, projecting radially inwardly from the cap 26, which is intended to cooperate with a ramp 42 which extends around a lower end 44 of the base 16 along an angular "α" sector corresponding to the angle formed between the first and second angular positions, to urge the cap 26 from its lower shutter and locking position to its intermediate position.
Enfin, la portée tubulaire 40 intérieure du capuchon comporte au moins un troisième élément, faisant saillie radialement vers l'intérieur du capuchon 26, qui est destiné, dans la seconde position angulaire, à coopérer avec un ressort à lame 38 verticalement flexible agencé à la périphérie de l'embase 16 pour former le moyen de rappel élastique de raideur déterminée.Finally, the inner tubular bearing surface 40 of the cap comprises at least a third element, projecting radially inwardly from the cap 26, which is intended, in the second angular position, to cooperate with a vertically flexible leaf spring 38 arranged at the end. periphery of the base 16 to form the elastic return means of determined stiffness.
Il sera compris que ces premier, deuxième et troisième éléments pourraient être découplés les uns des autres. Toutefois, par souci de simplification, la portée tubulaire 40 intérieure du capuchon comporte au moins un pion 46 qui constitue les premier, deuxième et troisième éléments faisant saillie radialement vers l'intérieur du capuchon 26.It will be understood that these first, second and third elements could be decoupled from each other. However, for the sake of simplification, the inner tubular bearing surface 40 of the cap comprises at least one pin 46 which constitutes the first, second and third elements projecting radially towards the inside of the cap 26.
Comme on l'a vu précédemment, la rampe 42 est agencée autour d'une extrémité inférieure 44 de l'embase 16. Dans la mesure où l'embase est de préférence réalisée en un matériau plastique, cette rampe 42 sera de préférence venue de matière avec l'embase 16. D'une man ière analogue, la butée supérieure 36 et le ressort à lame 38 pourraient être venus de matière avec l'embase 1 6.As has been seen previously, the ramp 42 is arranged around a lower end 44 of the base 16. Insofar as the base is preferably made of a plastic material, this ramp 42 will preferably come from material with the base 16. In a similar way, the upper stop 36 and the leaf spring 38 could be integral with the base 1 6.
Toutefois, dans le but de simpl ifier la fabrication du bouchon 1 0 à l'aide d'éléments pouvant être réal isés simplement par injection d'un matériau plastique, la périphérie de l'embase 16 reçoit une bague 48 qui porte au moins une butée supérieure 36 et un ressort 38 à lame.However, for the purpose of simplifying the manufacture of the cap 1 0 using elements that can be made simply by injecting a plastic material, the periphery of the base 16 receives a ring 48 which carries at least one upper stop 36 and a leaf spring 38.
Dans le mode de réal isation préféré de l'invention, par souci de symétrie et afin d'équil ibrer les efforts auxquels est soum is le capuchon 26, la portée tubulaire intérieure 40 du capuchon 26 comporte au moins deux pions 46 d iamétralement opposés, l'embase 1 6 comporte deux rampes 42 d iamétralement opposées, et la bague 48 comporte deux butées supérieures 38 et deux ressorts à lames 38 deux à deux diamétralement opposés.In the preferred embodiment of the invention, for the sake of symmetry and in order to balance the forces to which the cap 26 is subjected, the inner tubular surface 40 of the cap 26 comprises at least two pawns 46 dameteringly opposite, the base 1 6 comprises two ramps 42 iaméttralement opposite, and the ring 48 has two upper stops 38 and two leaf springs 38 two by two diametrically opposite.
Comme l'illustrent les figures 1 , 2 et 4 à 6, la bague 48 comporte un tronçon 50 cyl indrique tubulaire qu i comporte des moyens 52, 54 d'immobilisation verticale sur l'embase 16 et à partir duquel s'étendent verticalement deux pattes verticales 56 d iamétralement opposées dont chacune comporte un bord inférieur dont une face transversale inférieure 38 constitue la butée supérieure.As illustrated in FIGS. 1, 2 and 4 to 6, the ring 48 comprises a tubular inductive section 50cc which comprises means 52, 54 for vertical immobilization on the base 16 and from which two vertical flaps 56 d iamétralement opposed each of which comprises a lower edge, a lower transverse face 38 constitutes the upper stop.
Par ailleurs, deux lames élastiques, constituant le ressort à lames 38, sont venues de matière avec la bague 48. Les lames 38 s'étendent autour de la périphérie de l'embase 1 6. Une première extrémité 58 de chaque lame prolonge le bord inférieur de chaque patte 56 de la bague et une seconde extrém ité l ibre 60 de chaque lame 38 étant incurvée selon une concavité orientée vers l'extrém ité inférieure 42 de l'embase 1 6 pour immobil iser le pion 46 associé du capuchon 26 dans la seconde positon angulaire, comme représenté aux figures 1 et 6. Tout moyen connu de l'état de la technique pourrait permettre l'immobilisation axiale de la bague 48 sur l'embase 16. La bague pourrait ainsi âtre sertie, soudée ou collée.Furthermore, two resilient blades, constituting the leaf spring 38, are integral with the ring 48. The blades 38 extend around the periphery of the base 1 6. A first end 58 of each blade extends the edge lower end of each lug 56 of the ring and a second end l ibre 60 of each blade 38 being curved in a concavity oriented towards the lower end 42 of the base 1 6 to immobilize the associated pin 46 of the cap 26 in the second angular position, as shown in Figures 1 and 6. Any known means of the state of the art could allow the axial immobilization of the ring 48 on the base 16. The ring could thus be crimped, welded or glued.
Toutefois, dans le mode de réalisation préféré de l'invention, les moyens d'immobilisation verticale de la bague 48 sur l'embase comportent un bord inférieur 52 tronçon du tronçon cylindrique 50 tubulaire de la bague 48, qui est destiné à reposer sur une face supérieure 62 complémentaire d'un tronçon 64 de collerette faisant saillie radialement à partir de l'embase 16. Cette face supérieure s'oppose à la descente de la bague 48.However, in the preferred embodiment of the invention, the means for vertical immobilization of the ring 48 on the base comprise a lower edge 52 of the portion of the tubular cylindrical section 50 of the ring 48, which is intended to rest on a upper face 62 complementary to a section 64 of flange projecting radially from the base 16. This upper face opposes the descent of the ring 48.
Les moyens d'immobilisation verticale de la bague 48 sur l'embase comportent aussi un bourrelet intérieur 54 du tronçon 50 cylindrique tubulaire de la bague, présentant une section en forme d'ergot, qui est destiné à coopérer avec un bourrelet extérieur 66 qui fait saillie à la périphérie de l'embase 16 et qui présente une section en forme d'ergot complémentaire.The vertical immobilization means of the ring 48 on the base also comprise an inner bead 54 of the tubular cylindrical section 50 of the ring, having a pin-shaped section, which is intended to cooperate with an outer bead 66 which makes protrusion at the periphery of the base 16 and which has a section in the form of complementary pin.
Il sera enfin compris que la bague 48 permet d'assurer une fonction de guidage du capuchon 26. En effet, l'extrémité inférieure 44 de l'embase 16 et le tronçon cylindrique 50 de la bague 48 comportent chacun respectivement une portée cylindrique extérieure 68, 70 qui est destinée à coopérer avec la portée tubulaire intérieure 40 du capuchon 26 pour en assurer le guidage vertical .It will finally be understood that the ring 48 makes it possible to ensure a guiding function of the cap 26. In fact, the lower end 44 of the base 16 and the cylindrical section 50 of the ring 48 respectively comprise an outer cylindrical surface 68 70 which is intended to cooperate with the inner tubular bearing surface 40 of the cap 26 to ensure vertical guidance.
L'invention propose donc un bouchon 10 anti-goutte particulièrement innovant en ce qu'il permet d'éviter la dispersion et le séchage du produit ,et avantageux en ce qu'il est formé d'un nombre limité de pièces, et peut donc à ce titre être produit à un coût réduit en grande série. The invention therefore proposes an anti-drop plug 10 which is particularly innovative in that it makes it possible to prevent dispersion and drying of the product, and is advantageous in that it consists of a limited number of parts, and can therefore as such, be produced at a reduced cost in large series.
