Description

La présente invention se rapporte aux récipients utilisés pour le conditionnement de produits devant être distribués sous forme de mousse.The present invention relates to containers used for packaging products to be dispensed in the form of foam.

L'invention est, plus particulièrement, relative à la coiffe distributrice dont ces récipients doivent être munis et qui permet de répartir le produit moussant de façon précise.The invention relates, more particularly, to the dispensing cap with which these containers must be provided and which makes it possible to distribute the foaming product precisely.

Bien que l'invention concerne plus particulièrement la distribution sous forme de mousse de produits cosmétiques ou d'hygiène, elle peut être mise en oeuvre pour d'autres produits notamment des produits d'entretien de nettoyage et analogue.Although the invention relates more particularly to the distribution in the form of foam of cosmetic or hygiene products, it can be implemented for other products, in particular cleaning cleaning products and the like.

La technique antérieure a déjà fait connaître des distributeurs de produits divers combinés à des récipients du genre bombe aérosol mais leur réalisation est relativement complexe lorsqu'ils doivent comporter une tête distributrice développant le moussage du produit c'est-à-dire une tête munie d'une grille ou présentant des ouvertures calibrées par lesquelles le produit pulsé depuis le récipient doit passer et être brusquement détendu.The prior art has already made known distributors of various products combined with containers of the aerosol can type but their production is relatively complex when they have to include a dispensing head developing the foaming of the product, that is to say a head provided with '' a grid or having calibrated openings through which the product pulsed from the container must pass and be suddenly relaxed.

L'invention permet de réaliser une coiffe distributrice comportant seulement deux pièces pouvant être facilement fabriquées par moulage par injection de matière thermoplastique ou analogue de sorte que les opérations d'assemblage sont pratiquement inexistantes.The invention makes it possible to produce a distributor cap comprising only two parts which can be easily manufactured by injection molding of thermoplastic material or the like, so that the assembly operations are practically non-existent.

Conformément à l'invention, la coiffe distributrice de crème moussante pour récipient du genre bombe aérosol dans laquelle une pièce en forme d'enveloppe est enfilée et fixée sur une bague d'un récipient comportant une buse distributrice est caractérisée en ce que l'enveloppe forme, sur son dessus, des parties de guidage pour un poussoir distributeur délimitant des canaux communiquant avec la buse du récipient et menant à une chambre délimitée par le poussoir et un diffuseur formant une paroi de ladite chambre.According to the invention, the foaming cream dispenser cap for an aerosol container type container in which an envelope-shaped part is threaded and fixed on a ring of a container comprising a dispensing nozzle is characterized in that the envelope forms, on its top, guide parts for a dispensing pusher delimiting communicating channels with the container nozzle and leading to a chamber delimited by the pusher and a diffuser forming a wall of said chamber.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics of the invention will also emerge from the detailed description which follows.

Des formes de réalisation sont représentées, à titre d'exemples non limitatifs, au dessin annexé.Embodiments are shown, by way of nonlimiting examples, in the accompanying drawing.

La fig. 1 est une coupe-élévation de la coiffe distributrice de crème selon l'invention.Fig. 1 is a sectional elevation of the cream dispensing cap according to the invention.

La fig. 2 est une vue de dessus correspondant à la fig. 1.Fig. 2 is a top view corresponding to FIG. 1.

La fig. 3 est une perspective d'un poussoir distributeur que comporte la coiffe des figures précédentes.Fig. 3 is a perspective of a dispenser pusher that comprises the cover of the preceding figures.

La fig. 4 est une coupe-élévation analogue à la fig. 1 d'une variante.Fig. 4 is a sectional elevation similar to FIG. 1 of a variant.

La fig. 5 est une perspective d'une enveloppe que comporte la coiffe de la fig. 4.Fig. 5 is a perspective of an envelope that includes the cover of FIG. 4.

La fig. 6 est une perspective d'un poussoir distributeur que comporte la coiffe des fig. 4 et 5.Fig. 6 is a perspective of a dispenser pusher that comprises the cover of FIGS. 4 and 5.

La fig. 1 montre la partie supérieure d'un récipient 1 du type bombe aérosol destiné à contenir un produit crémeux devant être distribué sous forme d'une mousse.Fig. 1 shows the upper part of a container 1 of the aerosol can type intended to contain a creamy product to be dispensed in the form of a foam.

De façon connue, le récipient 1 comporte, à son extrémité supérieure, une bague saillante 2 servant, par exemple, au sertissage d'un couvercle comportant une vanne de distribution dont la buse 3 est seule représentée.In a known manner, the container 1 comprises, at its upper end, a projecting ring 2 serving, for example, for crimping a cover comprising a dispensing valve of which the nozzle 3 is only shown.

Dans ce type de dispositif, la vanne est ouverte en exerçant une poussée dans le sens de la flèche f₁ sur la buse 3.In this type of device, the valve is opened by pushing in the direction of the arrow f₁ on the nozzle 3.

La coiffe distributrice comporte une enveloppe 4 formant, à sa base, des butées de retenue 5, par exemple un jonc, engagées à force sur la bague saillante 2. Des butées 6 constituées par des nervures saillant de la paroi interne de l'enveloppe 4 sont prévues pour prendre appui sur le dessus de la bague 2 lorsque cette enveloppe est enfilée sur ladite bague ainsi que l'illustre la fig. 1.The distributor cap comprises a casing 4 forming, at its base, retaining stops 5, for example a rod, forcibly engaged on the projecting ring 2. Stops 6 constituted by ribs projecting from the internal wall of the casing 4 are provided to bear on the top of the ring 2 when this envelope is threaded on said ring as illustrated in FIG. 1.

L'enveloppe 4 délimite, sur son dessus, des parties de guidage 7, 8, par exemple en forme de nervures, qui sont engagées dans des rainures correspondantes 9, 10 que forme latéralement un poussoir distributeur 11 emboîté dans l'enveloppe 4 et retenu à l'intérieur de celle-ci par au moins une saillie 12.The envelope 4 delimits, on its top, guide parts 7, 8, for example in the form of ribs, which are engaged in corresponding grooves 9, 10 which laterally forms a dispensing plunger 11 fitted into the envelope 4 and retained inside thereof by at least one projection 12.

Le poussoir distributeur forme, sur son dessus, un plateau d'appui 13 permettant d'exercer une poussée, par exemple à l'aide d'un doigt.The dispenser plunger forms, on its top, a support plate 13 making it possible to exert a thrust, for example using a finger.

La fig. 1 montre que le poussoir 11 délimite un fût médian 14 percé d'un canal 15 aligné avec la buse 3 sur laquelle le fût médian 14 est partiellement enfilé.Fig. 1 shows that the pusher 11 defines a median barrel 14 pierced with a channel 15 aligned with the nozzle 3 on which the median barrel 14 is partially threaded.

Le canal 15 communique avec un canal transversal 16, par exemple oblique comme représenté, qui mène à une chambre 17 délimitée par un rebord 18 faisant avantageusement saillie au-delà d'une jupe 19 qui délimite la périphérie du poussoir et à partir de laquelle est formée la saillie de retenue 12.The channel 15 communicates with a transverse channel 16, for example oblique as shown, which leads to a chamber 17 delimited by a flange 18 advantageously projecting beyond a skirt 19 which delimits the periphery of the pusher and from which is formed the retaining projection 12.

Dans la réalisation représentée à la fig. 3, le poussoir est réalisé par moulage par injection d'une matière plastique en une seule pièce et comporte, sur un côté du rebord 18, une partie amincie 20 formant charnière au-delà de laquelle est formée une tête distributrice 21.In the embodiment shown in FIG. 3, the pusher is produced by injection molding of a plastic material in one piece and comprises, on one side of the rim 18, a thinned part 20 forming a hinge beyond which a dispensing head 21 is formed.

Le dessin montre que la tête distributrice comporte un diffuseur 22 constitué par une paroi dans laquelle sont pratiquées des ouvertures 23 ainsi que des éléments répartiteurs 24 pouvant, par exemple, présenter la forme de doigts entre lesquels le diffuseur 22 présente une partie pleine ou sensiblement pleine 25.The drawing shows that the dispensing head comprises a diffuser 22 constituted by a wall in which are made openings 23 as well as distributing elements 24 which can, for example, have the shape of fingers between which the diffuser 22 has a full or substantially full part. 25.

La tête distributrice 21 délimite, en outre, un manchon 26 destiné à être introduit à l'intérieur du rebord 18 pour y être emboîté et maintenu comme montré à la fig. 1.The dispensing head 21 further delimits a sleeve 26 intended to be inserted inside the rim 18 so as to be fitted and held there as shown in FIG. 1.

Le dessin montre que le canal transversal 16 débouche en regard de la partie pleine 25 avec laquelle les éléments répartiteurs 24 constituent une pré-chambre 17a.The drawing shows that the transverse channel 16 opens opposite the solid part 25 with which the distributing elements 24 constitute a pre-chamber 17a.

La description qui précède montre qu'en exerçant une poussée sur le plateau d'appui 13 cela a pour effet de faire coulisser le poussoir distributeur par rapport à l'enveloppe 4. Le dessus de l'enveloppe et, en particulier, les parties de guidage 7, 8 de celle-ci font que le poussoir distributeur 11 ne peut être déplacé qu'axialement par rapport au récipient 1. Le déplacement du poussoir distributeur 11 fait que la vanne du récipient 1 est ouverte par la pression qui est exercée sur le dessus de la buse 3.The above description shows that by exerting a push on the support plate 13 this has the effect of causing the dispensing pusher to slide relative to the envelope 4. The top of the envelope and, in particular, the guide parts 7, 8 thereof, cause the dispensing pusher 11 to be able to be moved only axially relative to the container 1. The movement of the pusher distributor 11 causes the container valve 1 to be opened by the pressure which is exerted on the top of the nozzle 3.

Le produit contenu dans le récipient 1 est ainsi pulsé par les canaux 15 et 16 et est amené dans la pré-chambre 17a formée entre les éléments répartiteurs 24 et qui favorise le moussage du produit pulsé par le brassage réalisé.The product contained in the container 1 is thus pulsed through the channels 15 and 16 and is brought into the pre-chamber 17a formed between the distributing elements 24 and which promotes the foaming of the pulsed product by the mixing carried out.

Le produit déjà moussant est ensuite propulsé à travers les ouvertures 23 du diffuseur 22 sous forme d'une mousse très développée qui peut facilement être utilisée soit en appliquant directement la tête distributrice 21 contre la partie devant recevoir la mousse soit en recueillant celle-ci par tous moyens au choix de l'utilisateur.The already foaming product is then propelled through the openings 23 of the diffuser 22 in the form of a highly developed foam which can easily be used either by directly applying the dispensing head 21 against the part to receive the foam or by collecting it by all means at the user's choice.

La description qui précède montre que l'ensemble du poussoir distributeur 11 avec sa tête distributrice 21 peut facilement être moulé en une seule pièce de sorte qu'aucun assemblage ultérieur n'est nécessaire.The foregoing description shows that the entire dispenser pusher 11 with its dispensing head 21 can easily be molded in one piece so that no subsequent assembly is necessary.

Il est même possible, si on le désire, de prévoir les éjecteurs du moule de fabrication de manière que la tête distributrice 21 soit pivotée autour de la partie amincie 20 formant charnière et que le manchon 26 soit introduit dans le rebord 18 pendant l'opération de démoulage.It is even possible, if desired, to provide the ejectors of the manufacturing mold so that the dispensing head 21 is pivoted around the thinned part 20 forming a hinge and the sleeve 26 is introduced into the flange 18 during the operation mold release.

Ainsi, le poussoir distributeur en une seule pièce n'a plus qu'à être mis en place dans l'enveloppe 4 par clipsage de la saillie 12, l'ensemble enveloppe 4, poussoir distributeur 11 étant lui-même mis en place en une seule opération sur la bague 2 du récipient 1.Thus, the dispenser pusher in one piece only has to be put in place in the casing 4 by clipping of the projection 12, the envelope assembly 4, dispenser pusher 11 being itself put in place in a single operation on the ring 2 of the container 1.

Les fig 4 à 6 illustrent une variante dans laquelle les mêmes numéros de référence désignent les mêmes organes qu'aux fig. 1 à 3, ces organes n'étant, par conséquent, pas décrits à nouveau.FIGS. 4 to 6 illustrate a variant in which the same reference numbers designate the same members as in FIGS. 1 to 3, these bodies therefore not being described again.

L'enveloppe 4 présente, sur son dessus, une partie de guidage 7a pouvant être de forme annulaire ou d'une autre forme qui dépend de celle de la jupe 19 du poussoir distributeur 11.The casing 4 has, on its top, a guide part 7a which may be of annular shape or of another shape which depends on that of the skirt 19 of the dispenser plunger 11.

La partie de guidage 7a bien visible à la fig. 5 délimite une encoche 27 à partir de laquelle est formé un segment 28 relié à l'enveloppe par une partie amincie 29 formant charnière. Le segment 28 est, par ailleurs, relié par une seconde partie amincie 29a formant également charnière à une patte 30 à partir de laquelle est formée la tête distributrice 21 formant le diffuseur 22 qui présente les ouvertures 23.The guide part 7a clearly visible in FIG. 5 defines a notch 27 from which is formed a segment 28 connected to the envelope by a thinned part 29 forming a hinge. The segment 28 is, moreover, connected by a second thinned part 29a also forming a hinge to a lug 30 from which the dispensing head 21 is formed, forming the diffuser 22 which has the openings 23.

Le segment 28 est courbe puisque destiné à être inséré dans l'encoche 27 délimitée par la partie de guidage 7a. De ce fait, il présente une flexibilité suffisante pour être déformé élastiquement.The segment 28 is curved since intended to be inserted in the notch 27 delimited by the guide part 7 a . Therefore, it has sufficient flexibility to be elastically deformed.

Le poussoir distributeur 11 est réalisé de manière analogue à ce qui est décrit précédemment, son rebord 18 étant prévu pour coopérer avec le manchon 26 que forme la périphérie de la tête distributrice 21.The dispenser pusher 11 is produced in a similar manner to that described above, its rim 18 being provided to cooperate with the sleeve 26 formed by the periphery of the dispensing head 21.

Les fig. 4 à 6 montrent une réalisation dans laquelle le manchon 26 emboîte le rebord 18 mais il serait possible que ce soit le rebord 18 qui emboîte le manchon 26 comme décrit en référence à la fig. 1.Figs. 4 to 6 show an embodiment in which the sleeve 26 fits the rim 18 but it would be possible that it is the rim 18 which fits the sleeve 26 as described with reference to FIG. 1.

Pour assurer un bon verrouillage de la tête distributrice 21 dans le rebord 18 du poussoir, il est prévu des saillies de verrouillage 31 qui sont formées par exemple comme représentées à partir de la patte 30. Les saillies de verrouillage pourraient, de manière analogue, être formées à partir d'une partie quelconque de la tête distributrice 21 ou du rebord 18 du poussoir.To ensure proper locking of the dispensing head 21 in the rim 18 of the pusher, there are provided locking projections 31 which are formed for example as shown from the tab 30. The locking projections could, similarly, be formed from any part of the dispensing head 21 or the rim 18 of the pusher.

Outre ce qui précède, la variante des fig. 4 à 6 montre que la tête distributrice 21 est munie, à sa partie devant venir en regard du canal 16 d'un élément répartiteur 24a se présentant sous la forme d'un bossage qui délimite, avec le fond de la chambre 17, une pré-chambre 17₁ par laquelle la crème est répartie de façon régulière dans toute la chambre 17, ce qui est illustré clairement par la fig. 4 qui montre que la pré-chambre 17₁ forme avec le bossage 24a une couronne distributrice 17₂.In addition to the above, the variant of FIGS. 4 to 6 shows that the dispensing head 21 is provided, at its part which comes opposite the channel 16, with a distributing element 24 a which is in the form of a boss which delimits, with the bottom of the chamber 17, a pre-chamber 17₁ through which the cream is evenly distributed throughout the chamber 17, which is clearly illustrated in FIG. 4 which shows that the pre-chamber 17₁ forms with the boss 24 has a distributor crown 17₂.

La fig. 5 fait bien ressortir que l'enveloppe 4 et la tête distributrice 21 reliées par le segment 28 et les parties amincies 29, 29a peuvent aisément être fabriquées par moulage en une seule pièce, l'ensemble tel qu'il est figuré à la fig. 5 correspondant à l'empreinte que doit présenter le moule. De même manière, le poussoir 11 peut être réalisé sans difficulté en une seule pièce pour être ensuite mis en place dans l'enveloppe 4 comme illustré par la fig. 4, position dans laquelle la tête distributrice 21 est rabattue par pliage des parties amincies 29, 29a et reliée rigidement au rebord 18 du poussoir, les saillies de verrouillage 31 étant engagées dans le poussoir 11 par une ouverture 32 de celui-ci.Fig. 5 makes it clear that the casing 4 and the dispensing head 21 connected by the segment 28 and the thinned parts 29, 29 a can easily be produced by molding in one piece, the assembly as shown in FIG. . 5 corresponding to the imprint that the mold must have. In the same way, the pusher 11 can be produced without difficulty in a single piece to then be put in place in the envelope 4 as illustrated in FIG. 4, position in which the dispensing head 21 is folded down by folding the thinned parts 29, 29 a and rigidly connected to the rim 18 of the pusher, the projections locking 31 being engaged in the pusher 11 through an opening 32 thereof.

Le fonctionnement est le même que celui décrit dans ce qui précède, c'est-à-dire que lorsqu'une pression est exercée sur le plateau d'appui 13 du poussoir 11, celui-ci est guidé par l'enveloppe 4 pour appuyer sur la buse 3.The operation is the same as that described in the foregoing, that is to say that when pressure is exerted on the support plate 13 of the pusher 11, the latter is guided by the casing 4 to press on nozzle 3.

Pendant le déplacement du poussoir 11, le segment 28 est déformé élastiquement.During the movement of the pusher 11, the segment 28 is elastically deformed.

Le dessin montre que, selon la variante des fig. 4 à 6, la tête distributrice présente une forme rectangulaire dont les grands côtés forment un angle aigu avec l'axe géométrique du récipient 1. Il va de soi que la forme de la tête distributrice pourrait être différente.The drawing shows that, according to the variant of FIGS. 4 to 6, the dispensing head has a rectangular shape whose long sides form an acute angle with the geometric axis of the container 1. It goes without saying that the shape of the dispensing head could be different.

L'invention n'est pas limitée aux exemples de réalisation représentés et décrits en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the embodiments shown and described in detail, because various modifications can be made without departing from its scope.
