Description

ENSEMBLE APPLICATEUR POUR COMPOSITION LIQUIDE, NOTAMMENT COSMETIQUE. APPLICATOR ASSEMBLY FOR LIQUID COMPOSITION, ESPECIALLY COSMETIC.
La présente invention est relative à un ensemble applicateur pour produit liquide ou pâteux tel qu'un produit cosmétique ; elle concerne plus particulièrement mais non exclusivement les produits du type "eye liner" ou "mascara".The present invention relates to an applicator assembly for a liquid or pasty product such as a cosmetic product; it relates more particularly but not exclusively to products of the "eye liner" or "mascara" type.
Un tel ensemble applicateur est notamment connu par le brevet français n° 2 603 780 dans lequel est décrit un flacon comportant un goulot, dont l'ouverture se rétrécit en direction du fond du flacon pour aboutir à un passage, dans lequel l'extrémité d'un pinceau applicateur vient pénétrer pour être imprégnée avec du produit cosmétique. Avec une pointe type "eye liner", donc très fine, le passage a un diamètre très réduit, dans lequel se produit un effet de capillarité suffisant pour que le flacon ne fuie pas, même lorsqu'il est mis tête en bas. Avec un produit de type "mascara", l' applicateur a nécessairement un plus gros diamètre et il en résulte que le diamètre du passage est au moins de l'ordre de 2 à 3,5 mm ; dans ce cas, le flacon fuit s'il est mis tête en bas, car il n'y a plus d'effet de capillarité.Such an applicator assembly is known in particular from French Patent No. 2 603 780 in which is described a bottle comprising a neck, the opening of which narrows towards the bottom of the bottle to lead to a passage, in which the end d '' an applicator brush penetrates to be impregnated with cosmetic product. With an "eye liner" type tip, therefore very fine, the passage has a very small diameter, in which a capillary effect is produced sufficient for the bottle not to leak, even when it is put upside down. With a “mascara” type product, the applicator necessarily has a larger diameter and it follows that the diameter of the passage is at least of the order of 2 to 3.5 mm; in this case, the bottle leaks if it is put upside down, because there is no more capillary effect.
La présente invention a pour but de supprimer cet inconvénient. Pour atteindre ce but, on propose, selon l'invention, de disposer l'élément applicateur dans un étui, qui empêche le passage du produit vers l'extérieur ; cependant on ménage des orifices capillaires dans l'étui pour maintenir l'imprégnation par capillarité de l'élément applicateur. Le brevet US-A-3 951 157 avait déjà proposé, dans un ensemble analogue, de mettre en place un élément applicateur dans un étui à fentes, mais ces fentes non capillaires coopéraient avec un produit pulvérulent et n'auraient pu empêcher l'écoulement d'un produit liquide.The object of the present invention is to eliminate this drawback. To achieve this goal, it is proposed, according to the invention, to have the applicator element in a case, which prevents the passage of the product to the outside; however, capillary orifices are provided in the case to maintain the impregnation by capillarity of the applicator element. US-A-3,951,157 had already proposed, in a similar assembly, to install an applicator element in a slot case, but these non-capillary slots cooperated with a powdery product and could not have prevented the flow of a liquid product.
FR-A-1 517 002 concerne un flacon pour vernis à ongles comportant un récipient tubulaire recevant l'applicateur, ce récipient tubulaire communiquant avec l'intérieur du flacon par un trou de remplissage qui n'est pas un orifice capillaire.FR-A-1 517 002 relates to a bottle for nail varnish comprising a tubular container receiving the applicator, this tubular container communicating with the interior of the bottle by a filling hole which is not a capillary orifice.
FR-A-1 076 477 concerne un joint déformable d'étenchéité plus particulièrement destiné aux produits à base de solvants très volatiles, par exemple vernis à ongles, et ne fait pas intervenir d'orifice capillaire. La présente invention a donc pour objet un ensemble applicateur pour produit liquide ou pâteux, tel qu'un produit cosmétique, comportant un flacon, qui délimite un réservoir pour le produit et qui est muni d'un goulot, et un capuchon amovible susceptible de fermer le goulot du flacon, le capuchon portant intérieurement une tige au bout de laquelle est fixé un élément applicateur de sorte que, pour la position de fermeture du capuchon, l'élément applicateur pénètre dans le flacon et soit imprégné par le produit, un épaulement étant porté par le capuchon et destiné, dans la position de fermeture du capuchon, à prendre appui sur un siège solidaire du flacon, ledit flacon renfermant un étui, dont l'évidement intérieur est adapté à la forme extérieure de l'élément applicateur, ledit étui étant disposé de telle sorte que, dans la position de fermeture du capuchon, l'élément applicateur vienne s'y loger, caractérisé par le fait que l'épaulement est un épaulement annulaire ménagé sur la tige, ledit siège étant de forme correspondante et comportant un orifice central permettant le passage dudit élément applicateur d'un côté à l'autre du siège, ledit siège étant lié audit étui, ledit étui comportant dans sa paroi au moins une ouverture capillaire permettant au produit d'imprégner l'élément applicateur mais empêchant l'écoulement du produit, depuis le réservoir où il se trouve vers l'extérieur.FR-A-1 076 477 relates to a deformable sealing joint more particularly intended for products based on very volatile solvents, for example nail varnish, and does not involve a capillary orifice. The present invention therefore relates to an applicator assembly for a liquid or pasty product, such as a cosmetic product, comprising a bottle, which defines a reservoir for the product and which is provided with a neck, and a removable cap capable of closing. the neck of the bottle, the cap internally carrying a rod at the end of which is fixed an applicator element so that, for the closed position of the cap, the applicator element penetrates into the bottle and is impregnated with the product, a shoulder being carried by the cap and intended, in the closed position of the cap, to bear on a seat secured to the bottle, said bottle containing a case, the internal recess of which is adapted to the external shape of the applicator element, said case being arranged so that, in the closed position of the cap, the applicator element is housed therein, characterized in that the shoulder is a shoulder only annular formed on the rod, said seat being of corresponding shape and comprising a central orifice allowing the passage of said applicator element from one side to the other of the seat, said seat being linked to said case, said case comprising in its wall at least a capillary opening allowing the product to impregnate the applicator element but preventing the flow of the product, from the reservoir where it is located towards the outside.
Ainsi la mise en place de l'élément applicateur ne conditionne plus, comme c'était le cas dans le brevet français 2 603 780, l'écoulement de fuite du produit, puisque le produit doit passer dans les ouvertures capillaires de l'étui; l'élément applicateur ne baigne plus directement dans le produit contenu dans le flacon, ce qui, au demeurant, évite la pollution du réservoir par l'élément applicateur, mais il s'imprègne du produit dans une sorte de mini réservoir auxiliaire constitué par l'étui, lequel étui est alimenté en produit par un passage capillaire qui lui est propre et qui est indépendant de la présence de l'élément applicateur. Ce seul fait assure déjà une certaine retenue du produit même lorsque le flacon est renversé ; toutefois l'ensemble applicateur est avantageusement réalisé avec un siège d'étanchéité aménagé dans le flacon et constitué d'un matériau élastique.Thus, the positioning of the applicator element no longer conditions, as was the case in French patent 2 603 780, the leakage flow of the product, since the product must pass through the capillary openings of the case; the applicator element no longer bathes directly in the product contained in the bottle, which, moreover, avoids pollution of the reservoir by the applicator element, but it permeates the product in a sort of mini auxiliary reservoir constituted by the 'case, which case is supplied with product by a capillary passage which is specific to it and which is independent of the presence of the applicator element. This fact alone already ensures a certain retention of the product even when the bottle is overturned; however, the applicator assembly is advantageously made with a sealing seat arranged in the bottle and made of an elastic material.
Selon un mode de réalisation préféré, la tige du capuchon de l'ensemble applicateur comporte un élément annulaire de claquage situé entre l'épaulement et le capuchon, en vis à vis d'un élément de claquage correspondant aménagé dans le flacon, l'encliquetage de l'un des éléments annulaires sur l'autre assurant le maintien du capuchon sur le flacon en position de fermeture avec établissement d'une pression entre l'épaulement de la tige et le siège d'étanchéité. L'utilisation d'une fermeture à encliquetage permet d'éviter une fermeture à pas de vis, qui implique l'adoption d'un diamètre externe important pour l'ensemble applicateur. De la sorte, le conditionnement selon l'invention peut être plus esthétique. Avantageusement, le goulot et le capuchon de l'ensemble applicateur comportent annulairement des formes ondulées correspondantes pour qu'une rotation relative du capuchon par rapport au flacon entraîne un déplacement axial progressif de l'un par rapport à l'autre et suffisant pour provoquer le désencliquetage des éléments de claquage de la tige et du flacon. Ainsi, pour éviter une ouverture trop brutale, un système du type décrit, par exemple, dans le brevet français 2 470 737, permet une ouverture progressive de sorte que la séparation du capuchon par rapport au goulot s'effectue sans secousse brutale, même si l'encliquetage est très dur pour assurer un appui énergique de l'épaulement de la tige sur son siège d'étanchéité.According to a preferred embodiment, the stem of the cap of the applicator assembly comprises an annular snap-in element located between the shoulder and the cap, facing a corresponding snap-fitting element arranged in the bottle, the snap-fastening of one of the annular elements on the other ensuring the maintenance of the cap on the bottle in the closed position with establishment of pressure between the shoulder of the rod and the sealing seat. The use of a snap closure makes it possible to avoid a screw thread closure, which implies the adoption of a large external diameter for the applicator assembly. In this way, the packaging according to the invention can be more aesthetic. Advantageously, the neck and the cap of the applicator assembly annularly have corresponding corrugated shapes so that a relative rotation of the cap relative to the bottle causes a progressive axial displacement of one relative to the other and sufficient to cause the release of the snap elements of the rod and of the bottle. Thus, to avoid an excessively rough opening, a system of the type described, for example, in French patent 2,470,737, allows a gradual opening so that the separation of the cap from the neck takes place without sudden jerking, even if the snap-fastening is very hard to ensure energetic support of the shoulder of the rod on its sealing seat.
Il est clair que la section droite de la (ou des) ouverture(s) capillaire(s) de l'étui sera d'autant plus grande que le produit est plus visqueux; on prévoit, de préférence, des ouvertures capillaires ayant chacune une section droite comprise entre 0,1 et 25 mm2 ; avantageusement, la paroi extérieure de l'étui est munie d'au moins une rainure capillaire aboutissant dans une ouverture capillaire, la rainure étant, par exemple, pratiquée dans un plan axial de l'étui. Selon une autre possibilité, la rainure peut se présenter sous forme annulaire selon un plan perpendiculaire à l'axe de l'étui. La rainure peut être notamment délimitée par deux bordures, qui convergent vers l'ouverture capillaire dans toute l'épaisseur de la paroi de l'étui. Ces rainures facilitent l'alimentation en produit des ouvertures capillaires et constituent des réserves pour l'imprégnation de l'élément applicateur.It is clear that the cross section of the capillary opening (s) of the case will be greater the more viscous the product; there are preferably provided capillary openings each having a cross section between 0.1 and 25 mm2; advantageously, the outer wall of the case is provided with at least one capillary groove terminating in a capillary opening, the groove being, for example, formed in an axial plane of the case. According to another possibility, the groove can be in annular form along a plane perpendicular to the axis of the case. The groove can in particular be delimited by two edges, which converge towards the capillary opening throughout the thickness of the wall of the case. These grooves facilitate the supply of product to the capillary openings and constitute reserves for the impregnation of the applicator element.
Lorsque l'élément applicateur a une forme généralement cylindrique, on peut prévoir, pour un bon essorage de l'élément applicateur, que l'orifice du siège ait une section légèrement inférieure à celle de l'élément applicateur. Selon un mode de réalisation préféré, l'élément de claquage, aménagé dans le flacon pour maintenir le capuchon en position de fermeture, est formé sur une entretoise, qui elle-même supporte un embout dont une extrémité forme l'étui, ledit embout portant un alésage axial où est aménagé le siège d'étanchéité.When the applicator element has a generally cylindrical shape, it can be provided, for good spinning of the applicator element, that the orifice of the seat has a section slightly smaller than that of the applicator element. According to a preferred embodiment, the snap-fitting element, arranged in the bottle to maintain the cap in the closed position, is formed on a spacer, which itself supports an end piece, one end of which forms the case, said end piece carrying an axial bore where the sealing seat is arranged.
Selon une variante, le siège d'étanchéité aménagé dans le flacon est constitué d'un matériau élastique. On peut aussi prévoir que l' entretoise soit réalisée en matériau élastique, notamment pour que l'encliquetage du capuchon sur le goulot assure une force d'appui maintenue élastiquement de l'épaulement de la tige sur son siège.Alternatively, the sealing seat in the bottle is made of an elastic material. One can also provide that the spacer is made of elastic material, in particular so that the snap-fastening of the cap on the neck ensures a pressing force resiliently maintained from the shoulder of the rod on its seat.
Toutes sortes d'éléments applicateurs sont prévus, notamment brosse ou feutre, plume, mousse, éventuellement floqué.All kinds of applicator elements are provided, in particular brush or felt, feather, foam, possibly flocked.
La présente invention sera mieux comprise avec la description de deux exemples de réalisation purement illustratifs et non limitatifs, représentés sur le dessin annexé. Sur ce dessin :The present invention will be better understood with the description of two purely illustrative and nonlimiting exemplary embodiments, shown in the accompanying drawing. On this drawing :
- la figure 1 représente, en coupe axiale, un ensemble applicateur selon une première variante de l'invention ;- Figure 1 shows, in axial section, an applicator assembly according to a first variant of the invention;
- la figure 2 représente, en détail, le système d'ouverture à ondulations de l'applicateur de la figure 1 ;- Figure 2 shows, in detail, the corrugated opening system of the applicator of Figure 1;
- la figure 3 représente, en coupe axiale, un ensemble applicateur selon une deuxième variante de l'invention ;- Figure 3 shows, in axial section, an applicator assembly according to a second variant of the invention;
- la figure 4 représente, en perspective, le système d'ouverture à ondulations de cette deuxième variante ; - la figure 5 représente en détail une variante de l'embout de l'ensemble applicateur de la figure 3.- Figure 4 shows, in perspective, the corrugated opening system of this second variant; FIG. 5 shows in detail a variant of the tip of the applicator assembly of FIG. 3.
- la figure 6 représente la modification d'un détail de la figure 1. Sur la figure 1, on a représenté un ensemble applicateur 1 en position fermée comportant un flacon 3 muni d'un goulot 4 et un capuchon 5 pour fermer le goulot. Le flacon 3 constitue un réservoir pour le produit 2, par exemple un mascara, que l'on veut distribuer avec ledit ensemble applicateur.- Figure 6 shows the modification of a detail of Figure 1. In Figure 1, there is shown an applicator assembly 1 in the closed position comprising a bottle 3 provided with a neck 4 and a cap 5 to close the neck. The bottle 3 constitutes a reservoir for the product 2, for example a mascara, which it is desired to distribute with said applicator assembly.
Le capuchon porte, solidaire avec lui, une tige 7 au bout de laquelle est fixé un élément applicateur 6 qui, dans le cas de la figure 1, est une brosse munie de poils très serrés ; mais ce pourrait tout aussi bien être un feutre, une plume, ou une mousse, floqué ou non, ou tout autre élément convenable pour l'application du produit 2 ; la forme représentée est sensiblement cylindrique mais un élément applicateur légèrement conique pointe en bas pourrait être utilisé.The cap carries, integral with it, a rod 7 at the end of which is fixed an applicator element 6 which, in the case of FIG. 1, is a brush provided with very tight bristles; but it could just as easily be a felt, a feather, or a foam, flocked or not, or any other element suitable for the application of the product 2; the form shown is substantially cylindrical but a slightly tapered applicator element pointing down could be used.
L'élément applicateur 6 est logé dans un étui 10 solidaire du flacon 3 ; la forme intérieure de l'étui 10 est adaptée à la forme extérieure de l'élément applicateur 6 de telle sorte que celui-ci s'imprègne du produit 2, lequel produit pénètre dans l'étui par au moins une ouverture capillaire ; deux variantes d'ouvertures capillaires sont représentées à savoir :The applicator element 6 is housed in a case 10 integral with the bottle 3; the internal shape of the case 10 is adapted to the external shape of the applicator element 6 so that the latter is impregnated with the product 2, which product enters the case through at least one capillary opening; two variants of capillary openings are shown, namely:
- une ouverture 11 circulaire avec un diamètre adéquat en fonction de la viscosité du produit ;- A circular opening 11 with an adequate diameter depending on the viscosity of the product;
- une ouverture 12 rectangulaire reliée à une rainure 13 aménagée longitudinalement sur la surface extérieure de l'étui 10, la rainure 13 ayant, dans un plan axial de l'étui 10, une forme triangulaire dont un sommet est occupé par l'ouverture 12. II est clair que, dans un même ensemble on préférera, s'il y a plusieurs ouvertures capillaires, qu'elles aient toutes la même conformation, la représentation des deux types d'ouverture sur la même figure 1 n'étant destinée qu'à illustrer deux réalisations possibles des ouvertures. Dans les deux cas, en fonction de la viscosité du produit, celui-ci vient constituer au niveau de l'ouverture 11, 12, une réserve capillaire de produit prêt à imprégner l'élément applicateur 6 ; la rainure 13 permet de faciliter l'accès du produit à l 'ouverture 12 et de constituer une réserve d'alimentation. Pour homogénéiser le produit, et/ou casser sa thixotropie par agitation, une bille 40 peut être mise dans le réservoir du flacon 3.- A rectangular opening 12 connected to a groove 13 arranged longitudinally on the outer surface of the case 10, the groove 13 having, in an axial plane of the case 10, a triangular shape whose apex is occupied by the opening 12 It is clear that, in the same assembly, it will be preferred, if there are several capillary openings, that they all have the same conformation, the representation of the two types of opening in the same FIG. 1 being intended only to illustrate two possible embodiments of the openings. In both cases, depending on the viscosity of the product, it comes to constitute at the opening 11, 12, a capillary reserve of product ready to impregnate the applicator element 6; the groove 13 makes it easier to access the product at the opening 12 and to constitute a supply reserve. To homogenize the product, and / or break its thixotropy by agitation, a ball 40 can be placed in the reservoir of the bottle 3.
Du fait que le produit 2 ne peut sortir du flacon que par les ouvertures capillaires 11,12, l'ensemble applicateur est déjà relativement étanche tant en position ouverte qu'en position fermée ; il est toutefois préférable de le munir d'un système d'étanchéité agissant en position fermée tel que celui représenté et réalisé par la coopération d'un épaulement annulaire tronconique 8 aménagé sur la tige 7 avec un siège tronconique 9 de forme correspondante aménagé sur une pièce entretoise 30 insérée dans le flacon. L'étui 10 constitue l'une des extrémités d'un embout 14, qui est retenu mécaniquement par son autre extrémité sur l' entretoise 30. La force d'appui nécessaire à ce système d'étanchéité est obtenue par un cordon de claquage 15 prévu sur la tige 7 pour prendre appui sur un épaulement 17 aménagé dans le goulot du flacon 3.Because the product 2 can only leave the bottle through the capillary openings 11, 12, the applicator assembly is already relatively sealed both in the open position and in the closed position; it is however preferable to provide it with a sealing system acting in the closed position such as that shown and produced by the cooperation of a frustoconical annular shoulder 8 arranged on the rod 7 with a frustoconical seat 9 of corresponding shape arranged on a spacer 30 inserted in the bottle. The case 10 constitutes one of the ends of a nozzle 14, which is mechanically retained by its other end on the spacer 30. The bearing force necessary for this sealing system is obtained by a snap-on bead 15 provided on the rod 7 to rest on a shoulder 17 arranged in the neck of the bottle 3.
Dans l'embout 14, il est prévu un étranglement 50, qui permet d'essorer ladite brosse lorsque l'usager va s'en servir en l'enlevant du flacon 3 ; ainsi un éventuel excès de produit 2 est enlevé du fait que le diamètre de l'orifice 50 est légèrement inférieur au diamètre extérieur de la brosse 6.In the end piece 14, a throttle 50 is provided, which allows said brush to be wrung when the user is going to use it by removing it from the bottle 3; thus a possible excess of product 2 is removed because the diameter of the orifice 50 is slightly less than the outside diameter of the brush 6.
La présence du cordon de claquage 15 et de l'épaulement 17 produit un effet d'encliquetage tant à la fermeture, ce qui est souhaité pour l'étanchéité, qu'à l'ouverture ce qui peut être néfaste en provoquant, par exemple, un éventuel risque de projection de gouttes du produit. Pour éviter cela, il est prévu, d'une part, une certaine souplesse dans le mode de fixation de l'embout 14 dans le flacon 3, d'autre part, un système d'ouverture comportant des ondulations du type décrit dans le brevet français 2 470 737.The presence of the snap cord 15 and the shoulder 17 produces a snap-action effect both at closing, which is desired for sealing, and at opening, which can be harmful by causing, for example, a possible risk of projection of drops of the product. To avoid this, there is provided, on the one hand, a certain flexibility in the method of fixing the nozzle 14 in the bottle 3, on the other hand, an opening system comprising corrugations of the type described in the patent French 2,470,737.
La souplesse souhaitée est réalisée au moyen de l'embout 14 qui constitue, d'une part, le siège d'étanchéité 9 et, d'autre part, l'étui 10 mais ceci n'est pas une obligation ; cette pièce unique est réalisée en un matériau élastique. Le matériau élastique, apte à fournir la souplesse souhaitée, peut être, par exemple, un caoutchouc naturel, un polyuréthane, un élastomère thermoplastique, un caoutchouc de nitrile ou de silicone, ou encore un polyéthylène.The desired flexibility is achieved by means of the end piece 14 which constitutes, on the one hand, the sealing seat 9 and, on the other hand, the case 10 but this is not an obligation; this unique piece is made of an elastic material. The elastic material, capable of providing the desired flexibility, can be, for example, a natural rubber, a polyurethane, a thermoplastic elastomer, a nitrile or silicone rubber, or even a polyethylene.
Un système d'ouverture facile, et donc progressive, est réalisable au moyen de formes ondulées 16 correspondantes disposées en vis à vis sur le goulot du flacon 3 et sur le capuchon 5, de sorte qu'en tournant légèrement le capuchon 5 autour de son axe, une force axiale suffisante est exercée pour désencliqueter le cordon de claquage 15 par rapport à l'épaulement 17. Dans cette variante, les ondulations 16 sont internes à l'ensemble applicateur de telle sorte qu'elles n'apparaissent pas vu de l'extérieur.An easy, and therefore progressive, opening system can be achieved by means of corresponding corrugated shapes 16 arranged opposite the neck of the bottle 3 and on the cap 5, so that by slightly turning the cap 5 around its axis, a sufficient axial force is exerted to disengage the snap bead 15 relative to the shoulder 17. In this variant, the corrugations 16 are internal to the applicator assembly so that they do not appear seen from the 'outside.
La figure 2 permet de bien visualiser le système d'ouverture à ondulations. En position de fermeture du capuchon, les ondulations s'interpénétrent comme des engrenages ; pour l'ouverture, en donnant au capuchon 5 un mouvement de rotation, comme s'il était vissé, le glissement des ondulations l'une sur l'autre provoque un déplacement axial du capuchon 5 par rapport au flacon 3, puisque la force résultant du couple exercé dans le sens rotatif se décompose, par réaction, en deux composantes dont l'une est axiale et provoque l'ascension du capuchon 5 et de son élément applicateur 6 associé.Figure 2 shows the ripple opening system. In the closed position of the cap, the corrugations interpenetrate like gears; for opening, by giving the cap 5 a rotational movement, as if it were screwed, the sliding of the corrugations one on the other causes an axial displacement of the cap 5 relative to the bottle 3, since the force resulting of the torque exerted in the rotary direction decomposes, by reaction, into two components, one of which is axial and causes the cap 5 and its associated applicator element 6 to rise.
La figure 3 est une variante assez similaire à celle de la figure 1 ; les éléments semblables ont les mêmes repères incrémentés de 300. Le flacon 303 est muni d'un goulot 304 ; le capuchon 305 est muni d'un élément applicateur 306 porté par une tige 307. Dans le goulot 304, on a mis en place une entretoise 330 dont la bordure supérieure est accrochée sur le bord libre du goulot et dont la partie inférieure supporte un embout 314, la partie inférieure dudit embout constituant un étui 310 où vient se loger l'élément applicateur 306. L'élément applicateur 306 est constitué en mousse et a une forme légèrement conique ; c'est pourquoi l'étui 310 a aussi une surface interne 325 légèrement conique dans le but d'obtenir une bonne imprégnation par le produit 302. Le produit 302 pénètre dans l'étui 310 par deux ouvertures capillaires 311,312, lesquelles sont ici représentées à l'identique avec une section circulaire.Figure 3 is a variant quite similar to that of Figure 1; similar elements have the same references incremented by 300. The bottle 303 is provided with a neck 304; the cap 305 is provided with an applicator element 306 carried by a rod 307. In the neck 304, a spacer 330 has been put in place, the upper edge of which is hung on the free edge of the neck and the lower part of which supports a nozzle. 314, the lower part of said end piece constituting a case 310 where the applicator element 306 is housed. The applicator element 306 is made of foam and has a slightly conical shape; this is why the case 310 also has an internal surface 325 which is slightly conical in order to obtain a good impregnation with the product 302. The product 302 enters the case 310 by two capillary openings 311, 312, which are shown here at the same with a circular section.
Dans la réalisation conforme à la figure 3, il se produit un pistonnage lors de la mise en place et lors de l'extraction de l'applicateur 306. Lors de l'extraction, ce pistonnage crée une dépression, d'où il résulte une amélioration du passage du liquide vers l'applicateur juste au moment de son extraction.In the embodiment according to Figure 3, there is a piston during the establishment and during the extraction of the applicator 306. During the extraction, this piston creates a vacuum, which results in a improvement of the passage of the liquid towards the applicator just at the time of its extraction.
Le même résultat peut être obtenu avec la réalisation de la figure 1 si l'on met en place sur la partie cylindrique disposée entre le cordon 15 et la portée conique 8 un bourrelet (voir figure 6) venant s'appuyer contre les parois cylindriques de l'élément 14. Pour éviter un pistonnage trop important, ce bourrelet peut être interrompu par des échancrures ê de façon à créer une fuite mais, néanmoins, à l'extraction de l'applicateur, il se créera une légère dépression.The same result can be obtained with the embodiment of FIG. 1 if a bead (see FIG. 6) comes to bear against the cylindrical walls of the cylindrical part disposed between the bead 15 and the conical bearing 8 element 14. To avoid excessive pistoning, this bead can be interrupted by notches ê so as to create a leak but, nevertheless, upon extraction of the applicator, a slight depression will be created.
Dans la variante de la figure 3, il n'y a pas de dispositif d'essorage, lequel serait inefficace compte tenu de la conicité de l'élément applicateur 306. La tige 307 comporte une portée tronconique 308, qui vient prendre appui sur un siège tronconique 309 agencé pour que l'ensemble constitue un système d'étanchéité similaire à celui de la figure 1 sous les repères 8 et 9. Le siège 309 est ménagé dans l'alésage axial de l'embout 314. L'élément d'encliquetage est réalisé par la coopération d'un épaulement 317 de l'entretoise 330 avec un épaulement 315 de la tige 307. Dans cette variante, l'entretoise 330 est beaucoup plus allongée et moins épaisse que celle de la figure 1, elle est réalisée en matériau élastique ; à l'encliquetage, la tige 307 est poussée élastiquement vers le siège tronconique 309, ce qui assure une bonne étanchéité par l'appui (siège 309/portée 308). Le système d'ouverture du flacon comporte des ondulations annulaires 316 pratiquées sur le goulot 304 et le capuchon 305 ; ces ondulations sont imbriquées l'une dans l'autre comme pour la réalisation de la figure 1 mais elles sont ici réalisées extérieurement, à la surface du flacon 303, de sorte que les ondulations 316 sont visibles de l'extérieur. Sur la figure 4, cette visibilité extérieure est bien montrée grâce à une vue en perspective. Le mode d'action des ondulations 316 est exactement le même que dans le cas des figures 1 et 2.In the variant of Figure 3, there is no wringing device, which would be ineffective given the taper of the applicator element 306. The rod 307 has a frustoconical bearing 308, which comes to bear on a frustoconical seat 309 arranged so that the assembly constitutes a sealing system similar to that of FIG. 1 under the references 8 and 9. The seat 309 is formed in the axial bore of the end piece 314. The element of snap-fastening is achieved by the cooperation of a shoulder 317 of the spacer 330 with a shoulder 315 of the rod 307. In this variant, the spacer 330 is much more elongated and less thick than that of Figure 1, it is made of elastic material; on snap-fastening, the rod 307 is pushed elastically towards the frustoconical seat 309, which ensures good sealing by the support (seat 309 / bearing 308). The bottle opening system comprises annular corrugations 316 made on the neck 304 and the cap 305; these corrugations are nested one inside the other as for the embodiment of FIG. 1 but they are here produced externally, on the surface of the bottle 303, so that the corrugations 316 are visible from the outside. In FIG. 4, this external visibility is well shown thanks to a perspective view. The mode of action of the corrugations 316 is exactly the same as in the case of FIGS. 1 and 2.
La figure 5 représente, en coupe axiale, un embout 514 convenable pour un élément applicateur légèrement conique (non représenté). L'étui 510 comporte dans cet exemple quatre ouvertures capillaires 512, (dont trois sont visibles sur la figure 5) de section rectangulaire, auxquelles aboutissent quatre rainures 513, pour amener le produit jusqu'à la zone d'imprégnation. La forme intérieure 525 de l'étui 510 a une conicité correspondant à celle de l'élément applicateur. On a désigné par 509 le siège tronconique qui assure l'étanchéité par coopération avec une portée de même nature de l'élément applicateur. Cet embout 514 peut être réalisé en matière élastique et il est destiné à être implanté dans un flacon de la même façon que l'embout 314 pour la variante de la figure 3. Figure 5 shows, in axial section, a tip 514 suitable for a slightly conical applicator element (not shown). The case 510 comprises in this example four capillary openings 512, (three of which are visible in FIG. 5) of rectangular section, to which four grooves 513 lead, to bring the product to the impregnation zone. The internal shape 525 of the case 510 has a conicity corresponding to that of the applicator element. The tapered seat which designates the seal by cooperation with a similar scope of the applicator element has been designated by 509. This tip 514 can be made of elastic material and it is intended to be implanted in a bottle in the same way as the tip 314 for the variant of FIG. 3.
