Description

La présente invention concerne un procédé de réalisation d'une recharge à poche, adaptée à se fixer sur un boîtier rechargeable au moyen d'une bague se vissant sur ledit boîtier, et une recharge à poche, comportant un couvercle adapté à se fixer sur un boîtier rechargeable au moyen d'une bague se vissant sur ledit boîtier.The present invention relates to a method of producing a pocket refill, adapted to be fixed on a refillable case by means of a ring screwing on said case, and a pocket refill, comprising a cover adapted to be fixed on a rechargeable housing by means of a ring screwing on said housing.

On connait des diffuseurs à poche non rechargeables comportant une valve disposée dans une coupelle sertie sur un dôme lui même serti sur le boîtier pour lesquels le remplissage de la poche est réalisé au travers de la valve.Non-refillable pocket diffusers are known having a valve disposed in a cup set on a dome itself crimped on the housing for which the filling of the bag is made through the valve.

Pour pouvoir propulser le produit au travers de la valve le boîtier est mis sous pression par l'injection d'un gaz entre la paroi interne du boîtier et la paroi externe de la poche ce qui comprime cette dernière et permet la sortie du produit lorsque la valve est manoeuvrée en position ouverte.In order to be able to propel the product through the valve, the casing is pressurized by the injection of a gas between the inner wall of the casing and the outer wall of the bag, which compresses the latter and allows the outlet of the product when the valve is operated in open position.

Le remplissage de la poche est délicat du fait qu'il est nécessaire de forcer le passage du produit au travers de la valve dans un sens inverse au sens de fonctionnement normal de cette dernière.The filling of the bag is difficult because it is necessary to force the passage of the product through the valve in a direction opposite to the normal operating direction of the latter.

Ce type de boîtier diffuseur est utile par exemple lorsqu'il est souhaitable de ne pas mélanger le produit avec le gaz propulseur ou lorsque le produit liquide ou pâteux est difficile à distribuer.This type of diffuser housing is useful for example when it is desirable not to mix the product with the propellant or when the liquid or pasty product is difficult to distribute.

Le document FR 2 785 594 A1 décrit aussi un boîtier diffuseur rechargeable comportant un réservoir et une recharge, la recharge étant fixée sur le réservoir par une bague et comportant un dôme formant couvercle muni d'un rebord externe au boîtier sur lequel est serti une coupelle porte valve.The document FR 2 785 594 A1 also discloses a rechargeable diffuser housing having a reservoir and a refill, the refill being fixed to the reservoir by a ring and having a lid dome provided with an outer rim to the housing on which is crimped a valve gate cup.

Selon ce document une poche est coincée entre une partie de corps de valve et une cheminée axiale du dôme.According to this document a pocket is wedged between a portion of the valve body and an axial chimney of the dome.

Le document FR 1 554 030 A décrit un boîtier diffuseur rechargeable comportant un réservoir réutilisable et un couvercle en coupole. Le couvercle en coupole qui se visse sur le réservoir reçoit une soupape. Un sac contenant un produit à pulvériser comporte une ouverture supérieure reliée de manière étanche à une bride d'étanchéité de la soupape.The document FR 1 554 030 A discloses a rechargeable diffuser housing having a reusable reservoir and a dome cover. The cupola lid which is screwed on the tank receives a valve. A bag containing a product to be sprayed has an upper opening sealingly connected to a sealing flange of the valve.

Un exemple de boîtier diffuseur rechargeable est décrit dans le document FR 2 951 140 A1 pour lequel un boîtier muni d'un rebord supérieur pourvu d'un pas de vis reçoit un dôme assujetti au boîtier au moyen d'une bague se vissant sur le boîtier.An example of a rechargeable diffuser housing is described in the document FR 2 951 140 A1 for which a housing provided with an upper rim provided with a screw thread receives a dome secured to the housing by means of a ring screwing on the housing.

Le dôme est solidaire d'une valve disposée dans une coupelle et sur laquelle une poche est fixée de manière étanche.The dome is integral with a valve disposed in a cup and on which a pocket is sealed.

Le montage de la valve sur le dôme est réalisé comme pour les boîtiers diffuseurs non rechargeable par sertissage d'une coupelle de la valve sur le dôme.The mounting of the valve on the dome is made as for non-refillable diffuser boxes by crimping a cup of the valve on the dome.

Ce boîtier a pour particularité de comporter une poche remplie d'un produit à pulvériser, un gaz propulseur étant injecté dans le boîtier autour de la poche qui est ainsi comprimée de sorte que le produit qu'elle contient est pulvérisé lorsque l'on ouvre la valve.This casing has the particularity of having a pocket filled with a product to be sprayed, a propellant being injected into the casing around the bag which is thus compressed so that the product it contains is sprayed when opening the container. valve.

Pour changer la poche une fois que la pression dans le boîtier est suffisamment basse, l'utilisateur dévisse la bague appliquant le dôme porteur de la valve sur le corps du boîtier et change l'ensemble dôme poche et valve.To change the pocket once the pressure in the housing is low enough, the user unscrews the ring applying the valve's dome carrier to the body of the housing and changes the pocket and valve dome assembly.

Une problématique d'un tel boîtier est le remplissage de la poche.A problem of such a housing is the filling of the pocket.

Il est en effet nécessaire que la poche soit vide pour réaliser l'opération de sertissage de la coupelle car la coupelle se fixe sur le dessus du dôme et il faut faire passer la poche au travers du trou de réception de la coupelle réalisé dans le dôme.It is indeed necessary that the bag is empty to perform the crimping operation of the cup because the cup is fixed on top of the dome and must pass the pocket through the receiving hole of the cup made in the dome .

Si on voulait souder la poche sur la valve après fixation de la coupelle sur le dôme, le dôme gênerait.If you wanted to weld the pocket on the valve after fixing the cup on the dome, the dome would interfere.

La présente invention pallie à ces problèmes tout en proposant un assemblage de valve sur dôme amélioré et un procédé associé.The present invention overcomes these problems while providing an improved dome valve assembly and associated method.

Pour ce faire, la présente invention prévoit un selon la revendication 1.For this purpose, the present invention provides a device according to claim 1.

Dans ce mode de réalisation, préalablement à l'étape d'encliquetage du profil de sertissage de la coupelle dans le logement, le procédé comprend avantageusement une étape de pose d'un joint dans le fond dudit logement.In this embodiment, prior to the latching step of the crimping profile of the cup in the housing, the method advantageously comprises a step of laying a seal in the bottom of said housing.

Alternativement, une étape de collage du profil de sertissage de la coupelle dans le logement est avantageusement ajoutée à l'étape d'encliquetage.Alternatively, a gluing step of the crimping profile of the cup in the housing is advantageously added to the latching step.

Selon un second mode de réalisation, la valve comprenant une surface supérieure d'assemblage sous le couvercle, l'étape d'assemblage comprend une étape complémentaire de fixation de la valve directement sous le couvercle.According to a second embodiment, the valve comprising an upper assembly surface under the cover, the assembly step comprises a complementary step of fixing the valve directly under the cover.

Selon un mode de réalisation particulier, préalablement à l'étape de remplissage de la poche, le procédé comprend une étape d'impression de caractéristiques du produit sur la poche et/ou de collage d'une étiquette sur la poche.According to a particular embodiment, prior to the step of filling the bag, the method comprises a step of printing product characteristics on the bag and / or sticking a tag on the bag.

L'étape de réalisation de la poche ouverte comporte avantageusement une étape de découpe de la poche et une étape de soudure de la poche sur trois côtés.The step of producing the open pocket advantageously comprises a step of cutting the pocket and a step of welding the pocket on three sides.

Le procédé comporte éventuellement une étape de pose d'un diffuseur ou d'un capot diffuseur et une étape de mise en carton de la poche équipée.The method optionally comprises a step of installing a diffuser or a diffuser cover and a cardboard packaging step of the equipped bag.

L'invention propose en outre une recharge à poche selon la revendication 10.The invention further provides a pocket refill according to claim 10.

Selon un premier mode de réalisation, le couvercle comporte une couronne pourvue d'un logement circulaire de réception d'une coupelle solidaire de la valve.According to a first embodiment, the lid comprises a ring provided with a circular housing for receiving a cup integral with the valve.

La présente invention perfectionne les boîtiers diffuseurs rechargeables en proposant un dispositif recharge amélioré et adapté à un remplissage de la poche avant montage sur la valve ainsi que le procédé associé.The present invention improves refillable diffuser housings by providing an improved charging device and adapted to fill the bag before mounting on the valve and the associated method.

Un premier mode de réalisation de l'invention est décrit en figure 1.A first embodiment of the invention is described in figure 1 .

Selon cette figure, le dispositif comporte une valve 3a de type traditionnel et comportant un corps de valve 31 et une coupelle 32 munie d'un profil annulaire 35 constitué par le rebord de sertissage de la coupelle normalement utilisé pour sertir la coupelle sur un dôme traditionnel.According to this figure, the device comprises a valve 3a of traditional type and comprising a valve body 31 and a cup 32 provided with an annular profile 35 constituted by the crimping rim of the cup normally used to crimp the cup on a traditional dome .

Le rebord de sertissage comporte un bord rabattu tourné vers l'extérieur de la coupelle.The crimping flange has a flanged edge facing outwardly of the cup.

Plus particulièrement représenté en figure 4, le couvercle 4a comporte une couronne 42 pourvue d'un logement circulaire 44 de réception de la coupelle 32 solidaire de la valve sous forme d'une gorge de retenue de la coupelle.More particularly represented in figure 4 , the cover 4a comprises a ring 42 provided with a circular housing 44 for receiving the cup 32 integral with the valve in the form of a retaining groove of the cup.

Le logement circulaire qui est un logement interne à la couronne 42 comporte selon cet exemple un bossage annulaire 41 d'encliquetage avec le profil annulaire 35 de la coupelle.The circular housing which is an inner housing to the ring 42 comprises according to this example an annular annular projection 41 of snap with the annular profile 35 of the cup.

Cette configuration permet de réutiliser une valve à coupelle de type traditionnel en encliquetant le bourrelet constitué par le rebord de sertissage dans le logement circulaire 44 du couvercle de l'invention. Selon l'invention, l'encliquetage se fait par le dessous du couvercle et réalise une étanchéité entre le couvercle 4a et la coupelle 32.This configuration makes it possible to reuse a traditional-type cup valve by snapping the bead constituted by the crimping rim into the circular housing 44 of the lid of the invention. According to the invention, the latching is done from below the lid and provides a seal between the lid 4a and the cup 32.

La figure 3 représentent le corps de valve 31, la coupelle 32 et la couronne 42 du couvercle démontées de sorte que l'on visualise les profils d'encliquetage du rebord de sertissage 35 de la coupelle 32 et de la gorge 44 munie de son bossage 41 assurant la rétention du rebord de sertissage de la coupelle.The figure 3 represent the valve body 31, the cup 32 and the crown 42 of the lid disassembled so that one visualizes the ratchet profiles of the crimping rim 35 of the cup 32 and the groove 44 provided with its boss 41 ensuring the retention of the crimping rim of the cup.

En variante représentée aux figures 7A et 7B, il est possible de disposer un joint tel qu'un joint annulaire plat 36 ou un joint torique dans le fond de la gorge, ce joint étant comprimé lors de l'encliquetage de la coupelle pour accroître l'étanchéité entre la coupelle et le couvercle.As a variant represented in Figures 7A and 7B , it is possible to have a seal such as a flat ring seal 36 or an O-ring in the bottom of the groove, this seal being compressed during the snapping of the cup to increase the seal between the cup and the lid .

Selon cette figure le joint plat 36 est réalisé simultanément avec le joint annulaire 37 du couvercle 4a par moulage d'un élastomère sur le couvercle.According to this figure the flat gasket 36 is made simultaneously with the annular seal 37 of the lid 4a by molding an elastomer on the lid.

Toujours selon ces figures l'encliquetage de la coupelle 32 dans la gorge du couvercle 4a se fait au moyen d'une pluralité de bossages 41 a réalisés en bout de pattes d'encliquetage 39.Still according to these figures the snap of the cup 32 in the groove of the lid 4a is made by means of a plurality of bosses 41a made at the end of the latching lugs 39.

Une autre possibilité pour assurer une étanchéité entre le couvercle et la coupelle est de coller le rebord de sertissage 35 dans la gorge 44.Another possibility to ensure a seal between the lid and the cup is to stick the crimping flange 35 in the groove 44.

L'exemple de la figure 2 correspond à une variante pour laquelle la coupelle 32 est remplacée par une paroi supérieure annulaire 5 d'un couvercle monobloc sous lequel est directement fixée la valve.The example of figure 2 corresponds to a variant for which the cup 32 is replaced by an annular upper wall 5 of a monobloc lid in which is directly fixed the valve.

Dans cet exemple, la valve 3b est utilisée sans coupelle et est collée sous la paroi supérieure annulaire 5 du couvercle.In this example, the valve 3b is used without a cup and is glued under the annular upper wall 5 of the lid.

Cette paroi supérieure est muni d'une surface inférieure d'appui d'une face supérieure d'un corps de la valve 3b.This upper wall is provided with a lower bearing surface of an upper face of a body of the valve 3b.

La paroi 5 est munie d'un trou central de passage d'un tube 33 de sortie de la valve ce tube dépassant éventuellement d'un cylindre 34 traversant la paroi 5.The wall 5 is provided with a central hole through which a tube 33 of the valve outlet passes, this tube optionally extending beyond a cylinder 34 passing through the wall 5.

Le couvercle 4b monobloc comporte de moulage la paroi 5 est préférablement dans ce cas un couvercle plastique moulé.The one-piece cover 4b comprises molding the wall 5 is preferably in this case a molded plastic cover.

La paroi 5 est notamment la face inférieure d'une baignoire de logement d'un bouton diffuseur venant actionner le tube 33 de sortie de la valve.The wall 5 is in particular the underside of a bathtub housing a diffuser button actuating the tube 33 output of the valve.

La surface inférieure de la paroi annulaire 5 est une surface d'appui d'une face supérieure d'un corps de la valve 3b.The lower surface of the annular wall 5 is a bearing surface of an upper face of a body of the valve 3b.

Dans cette configuration, la pose de la poche sur la valve est encore simplifiée puisque elle peut se faire sur la valve sans couvercle ni coupelle, l'ensemble valve/poche étant ensuite solidarisé au couvercle.In this configuration, the laying of the pocket on the valve is further simplified since it can be done on the valve without lid or cup, the valve / bag assembly then being secured to the lid.

Selon la figure 2, la valve est collée sous la face inférieure de la paroi 5, selon la figure 8, la valve s'encliquette sous le couvercle au moyen bossages 41 b réalisés en bout de pattes 39a sous la paroi 5 du couvercle.According to figure 2 , the valve is glued under the underside of the wall 5, according to the figure 8 , the valve snaps under the cover by means of bosses 41b made at the end of tabs 39a under the wall 5 of the lid.

Dans les deux modes de réalisation décrits aux figures 1 et 2, le couvercle 4a, 4b est préférablement un couvercle plastique conformé en dôme adapté à être posé sur un boîtier tel que celui du document FR 2 951 140 A1 et maintenu de manière étanche sur ce boîtier par une bague telle que décrite dans ce document.In both embodiments described in Figures 1 and 2 , the cover 4a, 4b is preferably a dome shaped plastic cover adapted to be placed on a housing such as that of the document FR 2 951 140 A1 and held tightly on this housing by a ring as described herein.

Dans les deux exemples représentés, la couronne 42 du couvercle est munie d'une gorge périphérique externe 43 d'encliquetage d'un capot 61, 63.In the two examples shown, the crown 42 of the cover is provided with an external peripheral groove 43 for snapping a cover 61, 63.

La valve peut être munie d'un simple bouton diffuseur 62 ou munie d'un capot diffuseur 63 tel qu'un capot de sécurité connu du document FR 2 750 960 .The valve may be provided with a simple diffuser button 62 or provided with a diffuser cover 63 such as a safety cover known from the document FR 2,750,960 .

Dans ce dernier cas le capot de sécurité s'encliquette en lieu et place du capot 61.In the latter case, the safety cover snaps in place of the cover 61.

Le dispositif de l'invention est particulièrement adapté à un remplissage de la poche avant son montage sur la valve puis à l'assemblage de la poche sur la valve 3a, 3b, la fixation de la valve sous le couvercle étant faite après fixation de la poche sous la valve sans que la poche ait à traverser le couvercle par le trou de réception de la valve.The device of the invention is particularly suitable for filling the bag before mounting it on the valve and then assembling the bag on the valve 3a, 3b, the fixing of the valve under the lid being made after fixing the pocket under the valve without the bag having to go through the lid through the receiving hole of the valve.

La figure 5 représente les étapes de fabrication d'un dispositif recharge selon le mode de réalisation de la figure 1.The figure 5 represents the steps of manufacturing a charging device according to the embodiment of the figure 1 .

L'étape 10 schématise la découpe d'une ébauche de poche 1, ébauche ensuite repliée puis dont les bords sont soudés sur trois côtés à l'étape de réalisation de la poche ouverte sur un côté schématisée en 20.Step 10 schematizes the cutting of a blank pocket 1, then folded folded and whose edges are welded on three sides at the step of producing the open pocket on a side shown schematically at 20.

L'étape 30 schématise le remplissage de la poche au moyen d'un dispositif doseur 2.Step 30 schematizes the filling of the bag by means of a measuring device 2.

Une fois la poche remplie, l'étape 40 schématise la fixation de la poche 1 sur la valve 3a équipée de sa coupelle.Once the bag is filled, step 40 schematizes the attachment of the bag 1 on the valve 3a equipped with its cup.

L'étape 40a correspond à l'amenée de la valve 3a, l'étape 40b à la soudure de la poche sur le tube inférieur 3c de la valve, le corps 31 de la valve dépassant de la poche.Step 40a corresponds to the supply of the valve 3a, step 40b to the welding of the bag on the lower tube 3c of the valve, the body 31 of the valve protruding from the bag.

Après l'étape de fixation 40 de la poche sur la valve le procédé comprend une étape d'assemblage 51 de la valve avec un couvercle 4a, de fermeture du boîtier, par le dessous du couvercle.After the fixing step 40 of the bag on the valve the method comprises a step of assembling 51 of the valve with a lid 4a, closing the housing, from below the lid.

Dans le cas où le dispositif comporte un joint entre le rebord de la coupelle et le logement, on réalise une étape de pose d'un joint dans le fond dudit logement, préalablement à l'étape d'encliquetage du profil de sertissage de la coupelle.In the case where the device comprises a seal between the rim of the cup and the housing, a step is made to install a seal in the bottom of said housing, prior to the detent step of the crimping profile of the cup .

Cette étape de pose de joint 36 peut être réalisée lors de la fabrication du couvercle par un procédé de moulage bi-matière.This seal installation step 36 can be performed during the manufacture of the lid by a bi-material molding process.

Il est aussi possible d'ajouter une étape de collage du profil de sertissage de la coupelle dans le logement à l'étape d'encliquetage.It is also possible to add a gluing step of the crimping profile of the cup in the housing in the detent step.

Le dispositif est représenté en fin d'assemblage à la figure 8 pour laquelle la valve 31 équipée de sa poche 1 remplie est encliquetée sous le couvercle 4a muni de son capot 61 et d'un bouton diffuseur 62.The device is shown at the end of assembly at the figure 8 for which the valve 31 equipped with its filled pocket 1 is snapped under the cover 4a provided with its cover 61 and a diffuser button 62.

L'exemple de la figure 6 correspond au second mode de réalisation selon la figure 2 pour lequel le corps de valve vient se fixer directement sous le couvercle par collage ou encliquetage selon la figure 7C.The example of figure 6 corresponds to the second embodiment according to the figure 2 for which the valve body is fixed directly under the cover by gluing or latching according to Figure 7C.

Selon ce mode de réalisation, les étapes de réalisation 20 de la poche 1, de remplissage 30 et de fixation de la poche sur la valve 40a, 40b sont les mêmes que dans le premier mode de réalisation.According to this embodiment, the steps of making the pocket 1, filling 30 and fixing the pocket on the valve 40a, 40b are the same as in the first embodiment.

Par contre, la valve comprenant une surface supérieure de fixation directement sous le couvercle, l'étape d'assemblage 50 comprend une étape de fixation de la valve sous le couvercle 4b par collage ou encliquetage, le tube 33 de sortie de la valve traversant la paroi annulaire 5 du couvercle.By cons, the valve comprising an upper fixing surface directly under the cover, the assembly step 50 comprises a step of fixing the valve under the cover 4b by gluing or snap-fitting, the outlet tube 33 of the valve passing through the annular wall 5 of the lid.

La figure 9 représente le dispositif en fin d'assemblage, le dispositif comportant selon cet exemple la valve 31 équipée de sa poche 1 remplie collée sous le couvercle 4b muni d'un capot diffuseur 63.The figure 9 represents the device at the end of assembly, the device comprising according to this example the valve 31 equipped with its filled pocket 1 glued under the cover 4b provided with a diffuser cover 63.

Dans les deux modes de réalisation, préalablement à l'étape de remplissage 30 de la poche, le procédé peut comprendre une étape d'impression de caractéristiques du produit sur la poche et/ou de collage d'une étiquette sur la poche.In both embodiments, prior to the step of filling the bag, the method may include a step of printing product features on the bag and / or sticking a tag on the bag.

Chacun des modes de réalisation décrits est parfaitement adapté à la fabrication de recharges valves à poches, le processus de fabrication de ces recharges étant un processus continu avec remplissage des poches puis fixation des poches remplies sur les valves de diffusion.Each of the described embodiments is perfectly suited to the manufacture of pocket valve refills, the process of manufacturing these refills being a continuous process with filling the pockets and then fixing the filled pockets on the diffusion valves.

Une fois les recharges terminées, il est possible de réaliser directement la pose d'un bouton diffuseur 62 ou d'un capot diffuseur 63 sur le tube de sortie de la valve et la pose éventuelle d'un capot 61.Once refills are complete, it is possible to directly perform the installation of a diffuser button 62 or a diffuser cover 63 on the outlet tube of the valve and the possible installation of a cover 61.

Il n'y a plus qu'à réaliser une étape de mise en carton des poches équipées pour les commercialiser.It is only necessary to carry out a cardboard packaging step equipped to market them.
