Abstract

This unit (1) comprises a recipient (2) on which is mounted a distribution head (3). The latter comprises a rotating cover (16) which is maintained on the recipient (2), and whose operation causes the translation of an adapter (13) mounted in a sliding manner on the neck (5) of the bottle. It is thus possible to open and close an upstream valve whose moving part is a plate (18) of the said adapter (13) and whose seat (37) is carried by the cover (16). The plate (18) serves as a support for a spring (14) drawing an applicator (15) into a position of closure of a downstream valve whose seat is carried by the cover (16). The downstream valve opens by the pushing in of the protruding end-piece (49) of the said applicator (15) when it is placed on the support intended to receiver the substance. The position in which the upstream valve is open corresponds to the "ready to use" position, the downstream valve still being closed. The position in which the upstream valve is closed blocks the downstream valve and ensures perfect fluid-tightness. <IMAGE>

Description

La présente invention se rapporte a un ensemble permettant de conditionner une substance fluide, dans des conditions d'étanchéité satisfaisantes, et de la répartir de façon directe et contrôlée sur un support. A titre d'exemple, l'invention concerne un flacon équipé d'une tête de distribution permettant d'appliquer, sur le cuir chevelu, une composition capillaire que le coiffeur doit normalement répartir de façon régulière, par exemple, en procédant raie par raie.The present invention relates to an assembly making it possible to condition a fluid substance, under satisfactory sealing conditions, and to distribute it in a direct and controlled manner on a support. By way of example, the invention relates to a bottle equipped with a dispensing head making it possible to apply, to the scalp, a hair composition which the hairdresser should normally distribute regularly, for example, proceeding line by line .

Un ensemble distributeur connu à cet effet est représenté sur la figure 5 ; il est constitué par un flacon qui renferme la substance à distribuer et qui porte, sur sa sortie, un clapet commandant la distribution dans les conditions recherchées. Ce clapet est formé entre une partie fixe, ou obturateur A, et une partie mobile, ou applicateur B. L'obturateur est constitué par une jupe pénétrant en partie dans le goulot C du flacon et portant extérieurement un rebord périphérique d'accrochage sur la bordure supérieure dudit goulot. A son extrémité située hors du récipient, la jupe est réunie à un fond portant une ouverture centrale délimitée par une paroi tronconique s'évasant en direction de l'intérieur du récipient. L'applicateur comporte un embout en forme d'ogive faisant saillie hors du récipient et s'évasant, à sa base, suivant une paroi tronconique D par laquelle il pénètre dans l'ouverture précitée et qui se prolonge par un ressort hélicoïdal E. L'applicateur est fixé, par son extrémité opposée à l'embout, à la partie inférieure de la jupe de l'obturateur. Le ressort E est formé de deux bandes hélicoïdales de matière plastique, décalées de 180°. Par ailleurs, il est normalement prévu un capuchon F destiné à venir s'adapter sur l'embout de l'applicateur, avant le premier emploi. Le capuchon s'accroche par encliquetage sur la paroi latérale de l'embout, en venant en appui sur le fond de l'obturateur A. Cette disposition assure une étanchéité correcte lors du stockage, avant la première utilisation.A distributor assembly known for this purpose is shown in Figure 5; it consists of a bottle which contains the substance to be dispensed and which carries, on its outlet, a valve controlling the distribution under the desired conditions. This valve is formed between a fixed part, or shutter A, and a movable part, or applicator B. The shutter is constituted by a skirt partially penetrating into the neck C of the bottle and externally carrying a peripheral rim for hooking on the upper edge of said neck. At its end located outside the container, the skirt is joined to a bottom carrying a central opening delimited by a frustoconical wall widening towards the interior of the container. The applicator has a nipple-shaped tip protruding from the container and flaring at its base along a frustoconical wall D through which it enters the aforementioned opening and which is extended by a helical spring E. L 'applicator is fixed, by its end opposite to the tip, to the lower part of the shutter skirt. The spring E is formed by two helical bands of plastic material, offset by 180 °. Furthermore, it is normally provided with a cap F intended to come to fit on the tip of the applicator, before the first use. The cap hooks by snap-fastening on the side wall of the nozzle, coming to bear on the bottom of the shutter A. This arrangement ensures a correct seal during storage, before the first use.

Pour l'utilisation, on enlève le capuchon F précité par désencliquetage, et on applique l'ensemble distributeur, par l'embout de l'applicateur B, sur le cuir chevelu, à l'endroit choisi. L'applicateur B s'enfonce alors axialement dans l'obturateur A, ouvrant le clapet de commande de la distribution. Le liquide peut alors s'écouler sur le cuir chevelu. On peut notamment procéder à une application raie par raie, en faisant effectuer à l'embout une translation tout en maintenant l'appui dudit embout sur le cuir chevelu. Après la première utilisation, il est pratiquement impossible de replacer le capuchon F et celui-ci est donc jeté. Dans ces conditions, l'étanchéité n'est plus assurée que par la mise en appui de l'embase tronconique D de l'embout sur le siège de clapet correspondant, sous l'action du ressort E. On conçoit que cette étanchéité soit imparfaite.For use, the aforementioned cap F is removed by disengaging, and the dispenser assembly is applied, by the tip of the applicator B, to the scalp, at the chosen location. The applicator B then plunges axially into the shutter A, opening the dispensing control valve. The liquid can then flow onto the scalp. One can in particular carry out a line by line application, by making the tip perform a translation while maintaining the support of said tip on the scalp. After the first use, it is practically impossible to replace the cap F and it is therefore discarded. Under these conditions, the seal is no longer ensured except by the support of the frustoconical base D of the end piece on the corresponding valve seat, under the action of the spring E. It is understood that this seal is imperfect .

Le modèle d'utilité allemand n° 85-30̸070̸1 décrit un ensemble distributeur-applicateur sensiblement analogue, constitué par un récipient dont l'embouchure reçoit également un système obturateur/applicateur. L'obturateur est constitué par une cheminée pénétrant à force dans le goulot du récipient, ladite cheminée étant raccordée à un fond dépassant latéralement de celle-ci pour former une collerette venant en appui sur la bordure supérieure dudit goulot. Le fond comporte une ouverture centrale délimitée par une courte jupe dont la bordure interne est biseautée. L'applicateur est sensiblement identique à celui de l'ensemble connu décrit en premier lieu. La partie de jonction entre l'embout terminal en forme d'ogive et la partie constituant le ressort comprend une zone tronconique puis une zone cylindrique. La coopération de la zone cylindrique avec la surface intérieure de la courte jupe du fond de l'obturateur assure une étanchéité complète, dans la position initiale de stockage.The German utility model No. 85-30̸070̸1 describes a substantially similar dispenser-applicator assembly, consisting of a container, the mouth of which also receives a shutter / applicator system. The shutter is constituted by a chimney penetrating by force into the neck of the container, said chimney being connected to a bottom projecting laterally from the latter to form a flange bearing on the upper edge of said neck. The bottom has a central opening bounded by a short skirt whose internal border is beveled. The applicator is substantially identical to that of the known assembly described in the first place. The junction part between the end piece in the shape of an ogive and the part constituting the spring comprises a frustoconical zone then a cylindrical zone. The cooperation of the cylindrical zone with the inner surface of the short skirt of the bottom of the shutter ensures complete sealing, in the initial storage position.

Lorsque l'on enfonce l'applicateur lors de la première utilisation, la région tronconique de ce dernier vient en appui contre la bordure interne biseautée de la jupe de l'applicateur, ce qui constitue la position d'étanchéité en cours d'utilisation. Pour la distribution, il faut appuyer davantage sur l'embout en ogive pour libérer la substance. Les mêmes remarques concernant la réalisation de l'étanchéité, en position de fermeture après chaque prélèvement de la substance, s'appliquent dans le cas de l'ensemble selon ce modèle d'utilité allemand.When the applicator is pushed in during the first use, the frustoconical region of the latter comes to bear against the internal bevelled edge of the skirt of the applicator, which constitutes the sealing position during use. For the distribution, it is necessary to press more on the pointed tip to release the substance. The same remarks concerning the achievement of the seal, in the closed position after each sample of the substance, apply in the case of the assembly according to this German utility model.

La présente invention vise à remédier à ces inconvénients en assurant l'étanchéité totale de l'ensemble après chaque prélèvement de la substance dans la récipient. Pour atteindre cet objectif, il est prévu, conformément à la présente invention, en amont du clapet (dit clapet aval) formé entre l'obturateur et l'applicateur, un clapet supplémentaire (clapet amont), fermé en position de stockage et ouvert dans la position prête à l'emploi ; dans cette dernière position, la clapet commandant la distribution (clapet aval) est normalement fermé mais il peut s'ouvrir par une pression exercée sur l'embout de l'applicateur, pression qui repousse celui-ci vers l'intérieur de l'obturateur ; au contraire, quand le clapet amont est fermé, il bloque le clapet aval en position de fermeture.The present invention seeks to remedy these drawbacks by ensuring total tightness of the assembly after each withdrawal of the substance from the container. To achieve this objective, there is provided, in accordance with the present invention, upstream of the valve (called downstream valve) formed between the shutter and the applicator, an additional valve (upstream valve), closed in the storage position and open in the ready-to-use position; in this last position, the valve controlling the distribution (downstream valve) is normally closed but it can open by a pressure exerted on the tip of the applicator, pressure which pushes it towards the inside of the shutter ; on the contrary, when the upstream valve is closed, it blocks the downstream valve in the closed position.

L'applicateur, conforme à la présente invention, convient notamment à l'utilisateur désirant appliquer lui-même un produit capillaire raie par raie sur le cuir chevelu sans risque d'éclaboussure préalable.The applicator, in accordance with the present invention, is particularly suitable for the user wishing to apply a hair product line by line on the scalp without the risk of prior splashing.

La présente invention a donc pour objet le produit industriel nouveau que constitue un ensemble pour le conditionnement et la distribution d'une substance fluide sur un support, comprenant, d'une part, un récipient contenant la substance à distribuer, et, d'autre part, une tête de distribution adaptée sur l'embouchure de sortie dudit récipient, ladite tête de distribution étant constituée par un obturateur comportant des moyens permettant de la maintenir sur ledit récipient et une ouverture de sortie de la substance, la région bordant ladite ouverture constituant le siège d'un clapet aval dont la partie mobile est portée par un applicateur traversant ladite ouverture et normalement rappelé en position de bouchage étanche par un ressort porté par ledit obturateur, la sortie de la substance fluide n'étant possible que par l'enfoncement de l'applicateur vers l'intérieur de l'obturateur à l'encontre de l'action dudit ressort, cet enfoncement étant réalisé lors de l'appui de l'ensemble, par l'embout dudit applicateur, qui fait saillie hors dudit obturateur, sur le support devant être revêtu par la substance fluide, caractérisé par le fait que ledit obturateur est constitué de deux parties, à savoir, un capot externe comportant les moyens de fixation sur le récipient et formant le siège dudit clapet aval, et un adaptateur interne mécaniquement relié, par son embase au capot externe et susceptible de coulisser en translation par rapport au goulot dudit récipient, sans possibilité de rotation par rapport audit goulot, et servant, par son extrémité opposée à ladite embase, d'appui pour l'extrémité correspondante dudit ressort, ledit adaptateur formant la partie mobile d'un clapet amont, dont le siège est porté par ledit capot, ce dernier étant monté mobile en rotation autour dudit goulot et comportant des moyens complémentaires de moyens portés par ledit adaptateur pour assurer la translation de ce dernier entre une position de fermeture totale dans laquelle les deux clapets amont et aval sont bloqués en position fermée contre leur siège, et une position prête à l'emploi, dans laquelle le clapet amont est ouvert, mais le clapet aval est encore fermé sous l'action dudit ressort bien que susceptible de s'ouvrir par poussée sur l'embout.The present invention therefore relates to the new industrial product that constitutes an assembly for the packaging and distribution of a fluid substance on a support, comprising, on the one hand, a container containing the substance to be distributed, and, on the other hand part, a dispensing head adapted on the outlet mouth of said container, said dispensing head being constituted by a shutter comprising means making it possible to hold it on said container and an outlet opening for the substance, the region bordering said opening constituting the seat of a downstream valve, the movable part of which is carried by an applicator passing through said opening and normally returned to the sealed closure position by a spring carried by said obturator, the outlet of the fluid substance being possible only by pressing in of the applicator towards the inside of the shutter against the action of said spring, this depression being produced during ap then the assembly, by the tip of said applicator, which projects out of said shutter, on the support to be coated with the fluid substance, characterized in that said shutter consists of two parts, namely, an outer cover comprising the means for fixing to the container and forming the seat of said downstream valve, and an internal adapter mechanically connected, by its base to the external cover and capable of sliding in translation relative to the neck of said container, without possibility of rotation relative to said neck , and serving, by its end opposite to said base, as a support for the corresponding end of said spring, said adapter forming the movable part of an upstream valve, the seat of which is carried by said cover, the latter being mounted movable in rotation around said neck and comprising means complementary to means carried by said adapter for ensuring the translation of the latter between a fully closed position in which the two upstream and downstream valves are locked in the closed position against their seat, and a ready-to-use position, in which the upstream valve is open, but the downstream valve is still closed under the action of said spring although it may open by pushing on the end piece.

Conformément à un mode de réalisation préféré, le plateau de l'adaptateur vient, dans la position de fermeture totale, au voisinage immédiat ou en appui contre l'applicateur pour constituer une butée bloquant ledit applicateur dans la position de fermeture du clapet aval ; le siège du clapet amont est constitué par une zone de paroi interne du capot et sa partie mobile est constituée par un plateau dudit adaptateur, ledit plateau constituant également la région d'appui du ressort.In accordance with a preferred embodiment, the adapter plate comes, in the fully closed position, in the immediate vicinity or in abutment against the applicator to form a stop blocking said applicator in the closed position of the downstream valve; the seat of the upstream valve consists of an area of the inner wall of the cover and its movable part consists of a plate of said adapter, said plate also constituting the support region of the spring.

Par ailleurs, l'adaptateur comporte avantageusement des moyens délimitant de façon étanche un canal de sortie de la substance entre le goulot et le clapet amont.Furthermore, the adapter advantageously comprises means sealingly delimiting an outlet channel for the substance between the neck and the upstream valve.

Dans un mode de réalisation spécifique, l'embase de l'adaptateur comporte une jupe externe disposée autour du goulot, ladite jupe portant extérieurement au moins un plot qui coopère avec une rainure hélicoïdale portée intérieurement par une jupe cylindrique du capot, l'ensemble plot/rainure constituant les moyens complémentaires pour assurer, lors de la rotation du capot, le déplacement en translation de l'adaptateur par rapport au capot et au goulot, ladite jupe externe de l'embase portant intérieurement les moyens de blocage en rotation dudit adaptateur par rapport au goulot.In a specific embodiment, the base of the adapter comprises an external skirt disposed around the neck, said skirt carrying externally at least one stud which cooperates with a helical groove carried internally by a cylindrical skirt of the cover, the stud assembly / groove constituting the complementary means for ensuring, during the rotation of the cover, the translational movement of the adapter relative to the cover and to the neck, said outer skirt of the base internally carrying the means for blocking the rotation of said adapter relative to the neck.

L'adaptateur peut être constitué par un corps allongé raccordé à un fond constituant le plateau et qui est réuni, par des nervures radiales, à l'embase, ladite embase étant constituée par deux jupes coaxiales réunies à une de leurs extrémités par un fond, la jupe externe étant disposée entre le goulot et la jupe cylindrique du capot alors que la jupe interne est à l'intérieur du goulot, le fond portant, du côté opposé aux jupes, une bague susceptible de coulisser de façon étanche le long d'une jupe du capot, le canal de sortie de la substance étant délimité par la jupe interne, la bague et la jupe.The adapter can be constituted by an elongated body connected to a bottom constituting the plate and which is joined, by radial ribs, to the base, said base being constituted by two coaxial skirts joined at one of their ends by a bottom, the external skirt being disposed between the neck and the cylindrical skirt of the cover while the internal skirt is inside the neck, the bottom carrying, on the side opposite to the skirts, a ring capable of sliding in leaktight fashion along a skirt of the cover, the outlet channel of the substance being delimited by the internal skirt, the ring and the skirt.

Les moyens complémentaires de blocage en rotation de l'adaptateur par rapport au goulot sont constitués par des ailettes radiales internes de la jupe de l'embase, qui s'intercalent entre des ailettes radiales externes dudit goulot.The complementary means for blocking the rotation of the adapter with respect to the neck consist of internal radial fins of the skirt of the base, which are interposed between external radial fins of said neck.

La jupe cylindrique du capot porte intérieurement deux rainures hélicoïdales diamétralement opposées, s'étendant sur une distance correspondant à une manoeuvre d'un quart de tour du capot, la jupe externe de l'adaptateur portant extérieurement deux plots diamétralement opposés, l'extrémité de la course des plots dans les rainures, qui est la plus voisine du récipient, correspondant à la position d'ouverture du clapet amont et l'autre extrémité correspondant à sa position de fermeture.The cylindrical skirt of the cover internally carries two diametrically opposite helical grooves, extending over a distance corresponding to a quarter-turn operation of the cover, the external skirt of the adapter externally carrying two diametrically opposite studs, the end of the stroke of the studs in the grooves, which is closest to the container, corresponding to the open position of the upstream valve and the other end corresponding to its closed position.

La jupe du capot comporte, le long de sa bordure libre, un moyen d'accrochage sur le récipient pour assurer le maintien de l'obturateur sur ledit récipient.The skirt of the cover comprises, along its free edge, a means of attachment to the container to ensure the maintenance of the shutter on said container.

Egalement, le capot et l'adaptateur peuvent comporter des moyens complémentaires de mise en butée réciproque dans la position de fermeture totale.Also, the cover and the adapter may include additional means for abutment reciprocal in the fully closed position.

Conformément à d'autres caractéristiques de la présente invention, l'applicateur comporte un corps creux, disposé à l'intérieur du capot et guidé le long de la paroi intérieure de celui-ci, le ressort étant disposé à l'intérieur dudit corps ; le capot présente une forme allongée se rétrécissant en direction de l'applicateur ; et les parois en regard des clapets amont et aval sont tronconiques, s'évasant vers l'intérieur du récipient.In accordance with other characteristics of the present invention, the applicator comprises a hollow body, disposed inside the cover and guided along the interior wall of the latter, the spring being arranged inside said body; the cover has an elongated shape narrowing in the direction of the applicator; and the facing walls of the upstream and downstream valves are frustoconical, flaring towards the interior of the container.

Pour mieux faire comprendre l'objet de la présente invention, on va en décrire ci-après, à titre d'exemple purement illustratif et non limitatif, un mode de réalisation représenté sur le dessin annexé.To better understand the object of the present invention, there will be described below, by way of purely illustrative and nonlimiting example, an embodiment shown in the accompanying drawing.

  • FIG. 5 represents, in axial section, the device of the state of the art mentioned at the beginning of this description.

Si l'on se réfère aux figures 1 à 4, on voit que l'on a désigné par 1, un ensemble pour le conditionnement et l'application directe d'une composition liquide sur le cuir chevelu. L'ensemble 1 comprend un récipient 2, sur lequel est adaptée une tête de distribution 3 capable de passer d'une première position, dans laquelle elle assure l'étanchéité totale du bouchage, dans une seconde position, dans laquelle elle permet l'application de la substance contenue dans le récipient 2 dans les conditions recherchées, c'est-à-dire que l'ensemble 1 peut être retourné, sans qu'il y ait de fuite de substance hors du récipient 2 et que la substance liquide peut être appliquée sur le cuir chevelu quand on appuie l'embout de l'applicateur sur le cuir chevelu.If we refer to Figures 1 to 4, we see that we have designated by 1, an assembly for the conditioning and direct application of a liquid composition on the scalp. Set 1 includes a container 2, on which is adapted a dispensing head 3 capable of passing from a first position, in which it ensures complete sealing of the closure, in a second position, in which it allows the application of the substance contained in the container 2 under the conditions sought, that is to say that the assembly 1 can be turned over, without there being any leakage of substance out of container 2 and that the liquid substance can be applied to the scalp when the tip of the applicator is supported on the scalp.

Le récipient 2, constitué, par exemple, d'un flacon en matière plastique, présente un corps cylindrique 4, se raccordant à un goulot cylindrique axial 5 par un épaulement annulaire 6, qui est perpendiculaire à la paroi latérale cylindrique du corps du flacon 2, puis par une bague cylindrique axiale 7, elle-même reliée à la base du goulot 5 par un second épaulement annulaire 8, de plus petite largeur que l'épaulement 6.The container 2, consisting, for example, of a plastic bottle, has a cylindrical body 4, connecting to an axial cylindrical neck 5 by an annular shoulder 6, which is perpendicular to the cylindrical side wall of the body of the bottle 2 , then by an axial cylindrical ring 7, itself connected to the base of the neck 5 by a second annular shoulder 8, of smaller width than the shoulder 6.

La bague 7 comporte une gorge périphérique 9, dont le rôle est indiqué plus loin. Le goulot 5 présente un léger rétrécissement à son extrémité libre 10, où sa bordure intérieure 11 est biseautée. Par ailleurs, le goulot 5 comporte extérieurement, sauf dans sa région d'extrémité, des ailettes radiales 12, régulièrement réparties à sa périphérie, dont le rôle est indiqué plus loin.The ring 7 has a peripheral groove 9, the role of which is indicated below. The neck 5 has a slight narrowing at its free end 10, where its inner edge 11 is bevelled. Furthermore, the neck 5 has externally, except in its end region, radial fins 12, regularly distributed around its periphery, the role of which is indicated below.

La tête de distribution 3 comporte un adaptateur interne 13, maintenu, par son embase, sur ledit goulot 5, et dont la paroi supérieure sert d'appui à la base d'un ressort hélicoïdal 14 maintenant intérieurement l'applicateur 15 en butée contre un capot tournant 16, dont la manoeuvre provoque le déplacement en translation de l'adaptateur 13, entre les deux positions précitées.The dispensing head 3 comprises an internal adapter 13, held, by its base, on said neck 5, and the upper wall of which serves as a support for the base of a helical spring 14 internally holding the applicator 15 in abutment against a rotating cover 16, the operation of which causes the translation 13 of the adapter 13 to move between the two aforementioned positions.

L'adaptateur 13 est constitué par un corps cylindrique 17 raccordé, le long d'une de ses bordures, à un plateau 18. Dans la zone de raccordement entre le corps 17 et le plateau 18, la paroi externe de l'adaptateur 13 est biseautée, ce qui constitue une zone tronconique de butée 19, dont le rôle est indiqué plus loin.The adapter 13 is constituted by a cylindrical body 17 connected, along one of its edges, to a plate 18. In the connection zone between the body 17 and the plate 18, the external wall of the adapter 13 is beveled, which constitutes a frustoconical stop zone 19, the role of which is indicated below.

Le plateau 18 présente, en son centre, du côté extérieur, un bossage cylindrique 20 de même axe que le corps 17. Ce bossage 20 sert de guide pour la base du ressort hélicoïdal 14, dont la spire inférieure repose sur la zone annulaire 21 de la paroi externe du plateau 18.The plate 18 has, in its center, on the outside, a cylindrical boss 20 with the same axis as the body 17. This boss 20 serves as a guide for the base of the helical spring 14, the lower turn of which rests on the annular zone 21 of the outer wall of the plate 18.

Dans la région de bordure du corps 17, qui est opposée au plateau 18, la paroi externe de l'adaptateur 13 comporte quatre nervures radiales 22, qui sont disposées à 90° l'une de l'autre et dont la bordure inférieure 22a se situe dans le plan de la bordure libre du corps 17. Ces nervures 22 raccordent ledit corps 17 avec l'embase 23 qui relie l'adaptateur 13 au goulot 5.In the border region of the body 17, which is opposite to the plate 18, the external wall of the adapter 13 has four radial ribs 22, which are arranged at 90 ° from each other and whose lower border 22 has is located in the plane of the free edge of the body 17. These ribs 22 connect the said body 17 with the base 23 which connects the adapter 13 to the neck 5.

L'embase 23, extérieure au corps 17, se compose de deux jupes cylindriques, respectivement 24 et 25, de même axe que le corps 17, réunies à un fond annulaire plat 26, parallèle au plateau 18 et situé légèrement au-dessus du niveau de la bordure inférieure du corps 17, les deux jupes 24 et 25 étant orientées à l'opposé du corps 17 par rapport au fond 26.The base 23, external to the body 17, consists of two cylindrical skirts, respectively 24 and 25, of the same axis as the body 17, joined to a flat annular bottom 26, parallel to the plate 18 and located slightly above the level of the lower edge of the body 17, the two skirts 24 and 25 being oriented opposite the body 17 relative to the bottom 26.

La jupe intérieure 24 de l'embase 23 présente un diamètre externe égal au diamètre intérieur du goulot 5 dans sa région d'extrémité 10 ; sa bordure libre externe 27 est biseautée, ce qui facilite la pénétration de la jupe 24 dans le goulot 5.The internal skirt 24 of the base 23 has an external diameter equal to the internal diameter of the neck 5 in its end region 10; its external free edge 27 is bevelled, which facilitates the penetration of the skirt 24 into the neck 5.

La jupe externe 25 présente intérieurement des ailettes 28, en un nombre égal à celui des ailettes 12 portées extérieurement par le goulot 5 ; les ailettes 28 viennent, en position de montage de l'adaptateur 13, s'imbriquer entre les ailettes 12 de manière à empêcher la rotation de l'adaptateur 13 autour du goulot 5. La paroi extérieure de la jupe 25 comporte deux plots 29 décalés l'un de l'autre de 180°.The outer skirt 25 has internally fins 28, in a number equal to that of the fins 12 carried externally by the neck 5; the fins 28 come, in the mounting position of the adapter 13, to nest between the fins 12 so as to prevent rotation of the adapter 13 around the neck 5. The outer wall of the skirt 25 has two offset pads 29 from each other by 180 °.

Le fond annulaire 26 porte, à l'opposé des jupes coaxiales 24 et 25, une bague cylindrique 30 de même axe que celles-ci et de diamètre compris entre ceux des deux jupes précitées. La bordure libre interne 31 de la bague 30 est biseautée. Par ailleurs, les nervures 22 sont reliées, non seulement à la jupe interne 24, mais également à ladite bague 30 : au-dessus du fond 26, elles comportent une bordure 22b, parallèle à la bordure 22a, et, au-dessus de cette dernière, une bordure 22c s'inclinant en direction du corps 17, à l'opposé de la bordure 22a. Par ailleurs, le fond 26 comporte un bossage radial 32, dont l'emplacement par rapport aux plots 29 sera explicité plus loin.The annular bottom 26 carries, opposite the coaxial skirts 24 and 25, a cylindrical ring 30 of the same axis as the latter and of diameter between those of the two aforementioned skirts. The internal free edge 31 of the ring 30 is bevelled. Furthermore, the ribs 22 are connected, not only to the internal skirt 24, but also to said ring 30: above the bottom 26, they have a border 22 b , parallel to the border 22 a , and, above from the latter, a border 22 c inclining towards the body 17, opposite the border 22 a . Furthermore, the bottom 26 has a radial boss 32, the location of which relative to the studs 29 will be explained later.

Le capot 16 comporte une paroi latérale 33 en forme de cloche, qui est raccordée, à son extrémité la plus étroite, à un fond 34, perpendiculaire à l'axe longitudinal de symétrie dudit capot 16. Le fond 34 présente une ouverture circulaire centrale 35, limitée par une paroi dont la bordure interne 36 est biseautée. Dans sa région 16a, très peu évasée, qui est voisine du fond 34, le capot 16 présente une paroi interne cylindrique, laquelle se raccorde à la paroi interne de la région évasée 16b, d'épaisseur sensiblement constante, du capot 16, par une courte zone d'appui tronconique 37, s'évasant à l'opposé du fond 34, puis par un décrochement annulaire 38. Dans sa région 16b, le capot 16 présente intérieurement deux jupes cylindriques, respectivement 39 et 40, dont l'axe coïncide avec l'axe longitudinal du capot 16, et qui sont disposées de façon à diviser la région 16b en trois parties de longueur à peu près équivalente.The cover 16 has a bell-shaped side wall 33, which is connected, at its narrowest end, to a bottom 34, perpendicular to the longitudinal axis of symmetry of said cover 16. The bottom 34 has a central circular opening 35 , limited by a wall whose internal edge 36 is bevelled. In its region 16 has very little flared, which is adjacent to the bottom 34, the cover 16 has a cylindrical inner wall, which adjoins the inner wall of the flared region 16 b, of substantially constant thickness, of the cover 16, by a short tapered support zone 37, flaring opposite the bottom 34, then by an annular recess 38. In its region 16b , the cover 16 has two internally cylindrical skirts, respectively 39 and 40, whose axis coincides with the longitudinal axis of the cover 16, and which are arranged so as to divide the region 16 b into three parts of roughly equivalent length.

La jupe 39 présente, à son extrémité, une surépaisseur 41 dirigée vers l'extérieur et sa bordure externe 42 est biseautée. Le diamètre externe de la jupe 39, mesuré dans la région de la surépaisseur 41, est égal au diamètre interne de la bague 30.The skirt 39 has, at its end, an extra thickness 41 directed towards the outside and its external edge 42 is bevelled. The external diameter of the skirt 39, measured in the region of the additional thickness 41, is equal to the internal diameter of the ring 30.

La jupe 40 est relativement épaisse, sauf dans sa région d'extrémité libre, après un décrochement annulaire 43 de sa paroi interne. Dans la région d'extrémité 40̸a, la jupe 40 comporte un bourrelet annulaire 44 destiné à venir s'accrocher dans la gorge périphérique 9 du goulot 5, tout en conservant la possibilité de faire tourner le capot 16 autour de son axe de symétrie, qui est confondu avec l'axe du goulot 5. Dans la région restante 40b de plus grande épaisseur, la jupe 40 comporte deux rainures hélicoïdales 45 qui reçoivent les plots 29 portés par la jupe 25 de l'embase 23 de l'adaptateur 13. Les rainures 45 sont diamétralement opposées et s'étendent sur un quart de tour ; elles ont une section droite rectangulaire. Le capot 16 porte intérieurement, entre les jupes 39 et 40̸, une ailette radiale 46, dont la disposition par rapport aux rainures 45 sera explicitée ci-après.The skirt 40 is relatively thick, except in its free end region, after an annular recess 43 from its internal wall. In the end region 40̸ a , the skirt 40 includes an annular bead 44 intended to be hooked into the peripheral groove 9 of the neck 5, while retaining the possibility of rotating the cover 16 around its axis of symmetry, which coincides with the axis of the neck 5. In the remaining region 40 b of greater thickness, the skirt 40 has two helical grooves 45 which receive the studs 29 carried by the skirt 25 of the base 23 of the adapter 13 The grooves 45 are diametrically opposite and extend over a quarter of a turn; they have a rectangular cross section. The cover 16 internally carries, between the skirts 39 and 40̸, a radial fin 46, the arrangement of which with respect to the grooves 45 will be explained below.

L'applicateur 15 est constitué par un corps cylindrique creux 47 se raccordant, à l'une de ses extrémités, par un épaulement interne 48, à un embout creux 49, en forme d'ogive. Le corps 47 comporte extérieurement plusieurs ailettes radiales 50̸, régulièrement réparties à sa périphérie. L'épaulement 48 est délimité par un décrochement annulaire interne 51, servant d'appui pour le ressort 14, et par une zone d'appui externe tronconique 52 destinée à venir en appui, sous l'action du ressort 14, contre la bordure biseautée 36 du fond 34 du capot 16.The applicator 15 is constituted by a hollow cylindrical body 47 which is connected, at one of its ends, by an internal shoulder 48, to a hollow end piece 49, in the form of a warhead. The body 47 externally comprises several radial fins 50̸, regularly distributed around its periphery. The shoulder 48 is delimited by an internal annular recess 51, serving as a support for the spring 14, and by a frustoconical external support area 52 intended to come in support, under the action of the spring 14, against the bevelled edge 36 of the bottom 34 of the cover 16.

L'assemblage des éléments constituant l'ensemble 1 qui vient d'être décrit est réalisé de la façon suivante : dans le capot 16, retourné par rapport à la position qu'il occupe sur les figures 1 et 3, on introduit l'applicateur 15 de façon que la zone tronconique 52 vienne en appui contre la bordure 36 du fond 34 dudit capot 16. Le ressort 14 est introduit dans le corps 47 de l'embout 15, en étant mis en appui par l'une de ses extrémités contre le décrochement annulaire 51. Ensuite, on engage l'adaptateur 13, par son corps allongé 17, dans le sous-ensemble qui vient d'être constitué, et on engage les plots 29 dans les rainures hélicoïdales 45. Lors de ce mouvement, les parties biseautées 31 et 42 respectivement de la bague 30 et de la jupe 39 facilitent l'engagement de ladite bague 30 autour de ladite jupe 39. En fin de course, les positions relatives du capot 16 et de l'adaptateur 13 sont celles représentées sur la figure 1 : le bossage 32 de l'adaptateur 13 est venu en butée de fin de course contre l'ailette 46 du capot 16 et la région tronconique 19 du plateau 18 de l'adaptateur 13 est en appui contre la zone tronconique correspondante 37. Dans cette position, le ressort 14 est comprimé et il provoque la mise en appui de l'applicateur 15, par sa zone tronconique 52 contre la zone correspondante 36 du fond 34 : l'embout 49 de l'applicateur 15 fait donc saillie hors du capot 16. Le plateau 18 est en appui sur ou au voisinage immédiat de la bordure libre du corps 47 et empêche tout recul de l'applicateur 15.The assembly of the elements constituting the assembly 1 which has just been described is carried out as follows: in the cover 16, turned over with respect to the position it occupies in FIGS. 1 and 3, the applicator is introduced 15 so that the frusto-conical zone 52 comes to bear against the edge 36 of the bottom 34 of said cover 16. The spring 14 is introduced into the body 47 of the end piece 15, being supported by one of its ends against the annular recess 51. Then, the adapter 13 is engaged, by its elongated body 17, in the subassembly which has just been constituted, and the studs 29 are engaged in the helical grooves 45. During this movement, the bevelled parts 31 and 42 respectively of the ring 30 and of the skirt 39 facilitate the engagement of said ring 30 around said skirt 39. At the end of the race, the relative positions of the cover 16 and of the adapter 13 are those shown on Figure 1: the boss 32 of the adapter 13 is v enu in end-of-travel abutment against the fin 46 of the cover 16 and the frustoconical region 19 of the plate 18 of the adapter 13 is in abutment against the corresponding frustoconical zone 37. In this position, the spring 14 is compressed and it causes the pressing of the applicator 15, by its frustoconical zone 52 against the corresponding zone 36 of the bottom 34: the end piece 49 of the applicator 15 therefore protrudes out of the cover 16. The plate 18 is supported on or at immediate vicinity of the free edge of the body 47 and prevents any retraction of the applicator 15.

Il ne reste plus alors qu'à présenter axialement le sous-ensemble qui vient d'être constitué, au-dessus du flacon 2 dans lequel on a conditionné la substance à distribuer ; puis, par un mouvement de translation axiale, on encliquette le capot 16 par introduction du bourrelet 44 de sa jupe 40 dans la gorge 9 du goulot 5. Dans cette position, la bordure libre du capot 16 vient en léger appui sur la bordure externe de l'épaulement 6 du flacon 2.It then remains only to present axially the subassembly which has just been constituted, above the bottle 2 in which the substance to be dispensed has been conditioned; then, by an axial translational movement, the cover 16 is snapped in by introduction of the bead 44 of its skirt 40 into the groove 9 of the neck 5. In this position, the free edge of the cover 16 bears lightly on the external edge of the shoulder 6 of the bottle 2.

Le fonctionnement s'effectue de la façon suivante : lorsque l'utilisateur désire appliquer la substance contenue dans le flacon 2 sur une chevelure, il commence par faire tourner d'un quart de tour le capot 16, à partir de la position de la figure 1. La position de la figure 1 correspond à une obturation totalement étanche de l'ensemble 1, puisque cette obturation est doublement assurée, d'une part, par la fermeture du clapet amont, dont la partie mobile est constituée par le plateau 18 et le siège, par la zone de la paroi interne 37 du capot 16, et, d'autre part, par la fermeture du clapet aval, dont la partie mobile est constituée par l'épaulement 48 de l'applicateur 15.The operation is carried out as follows: when the user wishes to apply the substance contained in the bottle 2 to a hair, he begins by rotating the cover 16 a quarter of a turn, from the position of the figure 1. The position of FIG. 1 corresponds to a completely sealed obturation of the assembly 1, since this obturation is doubly ensured, on the one hand, by the closing of the upstream valve, the movable part of which is constituted by the plate 18 and the seat, by the zone of the internal wall 37 of the cover 16, and, on the other hand, by the closing of the downstream valve, the movable part of which is formed by the shoulder 48 of the applicator 15.

Après cette rotation du capot 16, l'ensemble 1 prend la position représentée sur la figure 3 : étant donné que l'adaptateur 13 est bloqué en rotation par rapport au goulot 5, par la présence des ailettes 12 et 28 imbriquées les unes dans les autres, il ne peut prendre qu'un mouvement de translation, qui est prévu vers le bas ainsi que le montre le dessin. Dans ce mouvement de translation, l'adaptateur 13 est guidé, au niveau de la bague 30, le long de la jupe 39 du capot 16.After this rotation of the cover 16, the assembly 1 takes the position shown in FIG. 3: given that the adapter 13 is locked in rotation relative to the neck 5, by the presence of the fins 12 and 28 nested one in the others, it can only take a translational movement, which is provided downward as shown in the drawing. In this translational movement, the adapter 13 is guided, at the level of the ring 30, along the skirt 39 of the cover 16.

Le mouvement de descente de l'adaptateur 13 libère le passage pour la substance entre les zones tronconiques 19 et 37 de l'adaptateur 13 et du capot 16 respectivement : le clapet amont s'ouvre. Toutefois, le ressort 14 continue à maintenir l'applicateur 15 contre la zone tronconique 34, c'est-à-dire que le clapet aval est toujours fermé, continuant à empêcher toute sortie de la substance. Ainsi, dans cette position, qui est la position "prêt à l'emploi", l'utilisateur peut retourner l'ensemble 1 sans qu'il y ait fuite de substance.The downward movement of the adapter 13 frees the passage for the substance between the frustoconical zones 19 and 37 of the adapter 13 and of the cover 16 respectively: the upstream valve opens. However, the spring 14 continues to hold the applicator 15 against the frustoconical zone 34, that is to say that the downstream valve is always closed, continuing to prevent any exit of the substance. Thus, in this position, which is the "ready to use" position, the user can return the assembly 1 without any substance leaking.

Pour l'application, il suffit d'appuyer l'applicateur 15 par l'embout 49 sur le cuir chevelu, ce qui est symbolisé sur la figure 4 par la flèche F. Ce mouvement repousse l'applicateur 15 vers l'intérieur du capot 16 en ouvrant le clapet aval, mouvement qui est rendu possible puisque l'adaptateur 13 a reculé vers le flacon 2. Dans cette opération, le coulissement de l'applicateur 15 est guidé le long de la paroi interne de la zone 16a du capot 16, par les ailettes radiales 50 du corps 47 de l'applicateur 15. La substance s'écoule entre les nervures 22 dans la région délimitée par la jupe interne 24 de l'embase 23, la bague 30 de cette dernière et la jupe 39 du capot 16, pour sortir par les clapets amont et aval.For the application, it suffices to press the applicator 15 by the tip 49 on the scalp, which is symbolized in FIG. 4 by the arrow F. This movement pushes the applicator 15 towards the inside of the hood. 16 by opening the downstream valve, movement which is possible since the adapter 13 has fallen into the vial 2. in this operation, the sliding of the applicator 15 is guided along the inner wall of the zone 16 has the cover 16, by the radial fins 50 of the body 47 of the applicator 15. The substance flows between the ribs 22 in the region delimited by the internal skirt 24 of the base 23, the ring 30 of the latter and the skirt 39 of the cover 16, to exit by the upstream and downstream valves.

Lorsque l'application est terminée, en relâchant la pression exercée sur l'applicateur 15, on replace celui-ci dans la position de la figure 3, puis, de façon inverse, en faisant à nouveau tourner le capot 16 d'un quart de tour, on replace l'ensemble 1 dans la position de fermeture totale par la mise en appui des parois tronconiques 19 et 37 du clapet amont.When the application is finished, by releasing the pressure exerted on the applicator 15, the latter is replaced in the position of FIG. 3, then, conversely, by again rotating the cover 16 by a quarter of turn, replace the assembly 1 in the fully closed position by pressing the frustoconical walls 19 and 37 of the upstream valve.
