Description

La présente invention concerne un diffuseur en matière plastique pour récipient sous pression.The present invention relates to a plastic diffuser for a pressure vessel.

On connaît par exemple selon la demande de brevet français n° 84 05476 déposée le 6 avril 1984 au nom de la demanderesse, un diffuseur en matière plastique pour récipient sous pression, comprenant une jupe annulaire destinée à être montée sur la coupelle de montage de la valve du récipient et une buse axiale de sortie comportant un ajutage destiné à prendre appui sur la tige à coulissement axial de la valve. Cette buse présente une paroi sensiblement perpendiculaire à la buse qui est reliée à la jupe annulaire par une charnière en matière plastique moulée d'une seule pièce avec cette jupe et cette buse. Cette paroi est également reliée à la jupe à l'opposé de la charnière par un ou plusieurs ponts de garantie cisaillables lors de la première utilisation du diffuseur.Are known for example according to French patent application No. 84 05476 filed April 6, 1984 in the name of the plaintiff, a plastic diffuser for pressure vessel, comprising an annular skirt intended to be mounted on the mounting cup of the container valve and an axial outlet nozzle comprising a nozzle intended to bear on the axially sliding rod of the valve. This nozzle has a wall substantially perpendicular to the nozzle which is connected to the annular skirt by a plastic hinge molded in one piece with this skirt and this nozzle. This wall is also connected to the skirt opposite the hinge by one or more shearable guarantee bridges during the first use of the diffuser.

La buse comporte sur son côté opposé à la charnière une surface d'appui en saillie par rapport à la paroi de la buse qui permet à l'utilisateur de faire pivoter la buse par flexion de la charnière et d'enfoncer la tige de la valve pour commander l'expulsion du produit contenu dans le récipient sous pression.The nozzle has on its side opposite the hinge a bearing surface projecting from the wall of the nozzle which allows the user to pivot the nozzle by bending the hinge and to push the valve stem to control the expulsion of the product contained in the pressure container.

Par ailleurs, cette charnière est disposée dans le plan de la paroi qui est sensiblement perpendiculaire à la buse.Furthermore, this hinge is arranged in the plane of the wall which is substantially perpendicular to the nozzle.

L'inconvénient de cette réalisation réside dans le fait, qui a été constaté par la demanderesse, qu'il n'est pas possible de faire pivoter suivant un angle suffisant, l'ensemble constitué par la buse et sa paroi, dans une direction opposée à celle qui permet l'actionnement de la valve, pour pouvoir accéder à l'espace situé entre la paroi de la buse et la coupelle de montage de la valve, afin de pouvoir nettoyer cet espace.The disadvantage of this embodiment lies in the fact, which has been observed by the applicant, that it is not possible to rotate at a sufficient angle, the assembly constituted by the nozzle and its wall, in an opposite direction to that which allows the actuation of the valve, in order to be able to access the space situated between the wall of the nozzle and the valve mounting cup, in order to be able to clean this space.

En effet, lorsqu'on fait pivoter la buse dans la direction précitée, on constate que la charnière se casse dès que l'on dépasse un certain angle de pivotement qui est insuffisant pour accéder à l'espace précité.In fact, when the nozzle is pivoted in the aforementioned direction, it can be seen that the hinge is breaks as soon as a certain pivot angle is exceeded which is insufficient to access the aforementioned space.

Un autre inconvénient de la réalisation connue évoquée ci-dessus, réside dans le fait, qui a également été constaté par la demanderesse, que la surface d'appui qui permet de commander l'actionnement de la valve se trouve à l'opposé de la charnière.Another drawback of the known embodiment mentioned above, resides in the fact, which has also been observed by the applicant, that the bearing surface which makes it possible to control the actuation of the valve is located opposite the hinge.

En effet, en raison de la distance relativement grande existant entre cette surface d'appui et la charnière, l'utilisateur est obligé d'enfoncer cette surface d'appui suivant une distance relativement grande pour commander l'expulsion du produit par la valve, ce qui affecte notablement la sensibilité de la commande de cette valve.Indeed, due to the relatively large distance existing between this bearing surface and the hinge, the user is forced to push this bearing surface over a relatively large distance to control the expulsion of the product by the valve, which significantly affects the sensitivity of the control of this valve.

De plus, pour des raisons techniques, et en particulier pour éviter que la charnière fragile soit soumise à des contraintes lorsqu'on appuie sur la surface précitée, celle-ci doit nécessairement être sensiblement perpendiculaire à l'axe de la buse, de sorte que l'utilisateur est obligé de plier son doigt et donc de crisper celui-ci pour appuyer sur cette surface, tandis que les autres doigts maintiennent le récipient sous pression.In addition, for technical reasons, and in particular to prevent the fragile hinge from being subjected to stresses when the above-mentioned surface is pressed, the latter must necessarily be substantially perpendicular to the axis of the nozzle, so that the user is forced to bend his finger and therefore to tighten it to press on this surface, while the other fingers keep the container under pressure.

Le but de la présente invention est de créer un diffuseur qui remédie à tous les inconvénients précités, sans que sa construction soit pour autant plus coûteuse que celle des réalisations connues.The object of the present invention is to create a diffuser which overcomes all the aforementioned drawbacks, without its construction being more expensive than that of known embodiments.

Suivant l'invention, ce diffuseur est caractérisé en ce que ladite paroi de la buse qui est sensiblement perpendiculaire à celle-ci, est reliée à la jupe par une patte relativement rigide logée dans un évidement ménagé dans la jupe, la charnière étant ménagée à l'extrémité de cette patte qui est opposée à la buse, cette charnière étant située à une certaine distance du plan de ladite paroi et en ce que la surface d'appui en saillie pour actionner la valve est ménagée sur le côté de la buse qui est adjacent à la charnière.According to the invention, this diffuser is characterized in that said wall of the nozzle which is substantially perpendicular thereto, is connected to the skirt by a relatively rigid tab housed in a recess formed in the skirt, the hinge being formed at the end of this tab which is opposite to the nozzle, this hinge being situated at a certain distance from the plane of said wall and in that the projecting bearing surface for actuating the valve is formed on the side of the nozzle which is adjacent to the hinge.

On a constaté que grâce à cette disposition de la charnière dans un plan décalé axialement par rapport au plan de la paroi de la buse, il était possible de faire pivoter l'ensemble constitué par la buse et ladite paroi dans une direction opposée à celle qui permet l'actionnement de la valve, suivant un angle suffisamment grand pour permettre l'accès dans l'espace situé sous cette paroi, en vue du nettoyage de cet espace, sans encourir le risque de déchirer la charnière.It was found that thanks to this arrangement of the hinge in a plane offset axially with respect to the plane of the wall of the nozzle, it was possible to pivot the assembly constituted by the nozzle and said wall in a direction opposite to that which allows actuation of the valve, at an angle large enough to allow access to the space located under this wall, for cleaning this space, without incurring the risk of tearing the hinge.

Par ailleurs, grâce à cette disposition de la charnière, il est possible, conformément à l'invention, de placer la surface d'appui pour commander l'actionnement de la valve sur le côté de la buse qui est adjacent à la charnière.Furthermore, thanks to this arrangement of the hinge, it is possible, in accordance with the invention, to place the bearing surface to control the actuation of the valve on the side of the nozzle which is adjacent to the hinge.

Ainsi, la commande de l'ouverture de la valve est rendue plus sensible. De plus, cette surface n'a plus besoin d'être perpendiculaire à l'axe de la buse, mais elle peut être inclinée vers la jupe, de sorte que l'utilisateur peut prendre appui sur cette surface latéralement contre la buse, sans plier ni crisper son doigt et dans des conditions beaucoup plus confortables que dans le cas des réalisations connues.Thus, the control of the opening of the valve is made more sensitive. In addition, this surface no longer needs to be perpendicular to the axis of the nozzle, but it can be inclined towards the skirt, so that the user can rest on this surface laterally against the nozzle, without bending nor tighten his finger and in much more comfortable conditions than in the case of known embodiments.

Selon une version préférée de l'invention, la jupe présente un épaulement destiné à recevoir un capuchon pour recouvrir la buse et la charnière est située au niveau de cet épaulement qui est lui-même situé sensiblement à mi-hauteur de la jupe, la patte étant en forme d'équerre et présentant une partie située dans le plan de ladite paroi de la buse et une partie qui est parallèle à la jupe, la surface extérieure de cette partie étant située sensiblement dans le prolongement de la face intérieure de la jupe.According to a preferred version of the invention, the skirt has a shoulder intended to receive a cap to cover the nozzle and the hinge is situated at the level of this shoulder which is itself located substantially at mid-height of the skirt, the tab being square-shaped and having a part situated in the plane of said wall of the nozzle and a part which is parallel to the skirt, the external surface of this part being situated substantially in the extension of the internal face of the skirt.

Ainsi, la disposition de la charnière est compatible avec la mise en place d'un capuchon pour recouvrir et protéger la buse ainsi que la charnière et les ponts de garantie cisaillables.Thus, the arrangement of the hinge is compatible with the installation of a cap to cover and protect the nozzle as well as the hinge and the bridges of shearable guarantee.

De plus, la zone de raccordement entre l'épaulement de la jupe et la patte en forme d'équerre, constitue un excellent emplacement de la charnière car, dans cette zone,la jupe est fermement maintenue par la coupelle de montage de la valve sur laquelle cette jupe est engagée, de sorte que la charnière ne risque pas de se déplacer latéralement lorsqu'on sollicite la surface d'appui ménagée sur le côté de la buse.In addition, the connection area between the shoulder of the skirt and the bracket-shaped tab constitutes an excellent location for the hinge because, in this area, the skirt is firmly held by the valve mounting cup on which this skirt is engaged, so that the hinge is not likely to move laterally when the bearing surface formed on the side of the nozzle is stressed.

D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.Other features and advantages of the invention will appear in the description below.

Dans la réalisation des figures annexées, le diffuseur 1 en matière plastique pour récipient 2 sous pression, contenant par exemple une crème, comprend une jupe annulaire 3 montée par encliquetage sur la coupelle de montage 4 de la valve 5 du récipient et une buse axiale 6 de sortie du produit contenu dans le récipient 2, comportant un ajutage 7 prenant appui sur la tige 8 à coulissement axial de la valve 5.In the embodiment of the appended figures, the plastic diffuser 1 for container 2 under pressure, containing for example a cream, comprises an annular skirt 3 snap-fitted on the mounting cup 4 of the valve 5 of the container and an axial nozzle 6 outlet of the product contained in the container 2, comprising a nozzle 7 bearing on the rod 8 with axial sliding of the valve 5.

Cette buse 6 présente une paroi 9 en forme de disque (voir figure 2) perpendiculaire à la buse 6, qui est reliée à la jupe annulaire 9 par une charnière 10 en matière plastique moulée d'une seule pièce avec cette jupe 3 et cette buse 6.This nozzle 6 has a disc-shaped wall 9 (see FIG. 2) perpendicular to the nozzle 6, which is connected to the annular skirt 9 by a hinge 10 made of plastic molded in one piece with this skirt 3 and this nozzle. 6.

La paroi 9 en forme de disque couvre sensiblement toute la largeur de la jupe 3 et est séparée de celle-ci par une fente circulaire 11 (voir figure 2).Cette paroi 9 est également reliée à la jupe 3 à l'opposé de la charnière 10 par deux ponts de garantie cisaillables 12.The disc-shaped wall 9 covers substantially the entire width of the skirt 3 and is separated from the latter by a circular slot 11 (see FIG. 2). This wall 9 is also connected to the skirt 3 opposite the hinge 10 by two shearable guarantee bridges 12.

La buse 6 comporte sur l'un de ses côtés une surface d'appui 13 en saillie par rapport à ladite paroi 9 en forme de disque qui permet à l'utilisateur de faire pivoter la buse 6 par flexion de la charnière 10 et d'enfoncer la tige 8 de la valve 5.The nozzle 6 has on one of its sides a bearing surface 13 projecting from said wall 9 in the form of a disc which allows the user to pivot the nozzle 6 by bending the hinge 10 and push in the stem 8 of the valve 5.

Conformément à l'invention, la paroi 9 en forme de disque de la buse 6 est reliée à la jupe 3 par une patte 14 relativement rigide, en forme d'équerre (voir figures 3 et 4) logée dans un évidement 15a ménagé dans la jupe 3 (voir figures 1 et 2).According to the invention, the disk-shaped wall 9 of the nozzle 6 is connected to the skirt 3 by a relatively rigid tab 14, in the form of a square (see FIGS. 3 and 4) housed in a recess 15a formed in the skirt 3 (see Figures 1 and 2).

La charnière 10 est ménagée à l'extrémité 14a de la patte 14 qui est opposée à la buse 6. De plus, cette charnière 10 est située sensiblement à mi-hauteur de la jupe 3.The hinge 10 is formed at the end 14a of the tab 14 which is opposite to the nozzle 6. In addition, this hinge 10 is situated substantially halfway up the skirt 3.

Par ailleurs, la surface d'appui 13 en saillie est ménagée sur le côté de la buse 6 qui est adjacent à la charnière 10.Furthermore, the projecting bearing surface 13 is formed on the side of the nozzle 6 which is adjacent to the hinge 10.

D'autre part, on voit sur les figures 3 et 4 que la jupe 3 présente un épaulement 15 recevant un capuchon 16 qui recouvre la buse 6 et que la charnière 10 est située au niveau de cet épaulement 15.On the other hand, it can be seen in FIGS. 3 and 4 that the skirt 3 has a shoulder 15 receiving a cap 16 which covers the nozzle 6 and that the hinge 10 is located at the level of this shoulder 15.

Sur la figure 4, on voit de façon plus précise que la patte en forme d'équerre 14 présente une partie 17 située dans le plan de la paroi 9 en forme de disque de la buse 6 et une partie 18 qui est parallèle à la jupe 3. La surface extérieure 18a de cette partie 18 est située sensiblement dans le prolongement de la face intérieure 3a de la jupe 3.In FIG. 4, it can be seen more precisely that the bracket-shaped tab 14 has a part 17 situated in the plane of the wall 9 in the form of a disc of the nozzle 6 and a part 18 which is parallel to the skirt. 3. The external surface 18a of this part 18 is situated substantially in the extension of the internal face 3a of the skirt 3.

De plus, la surface externe 18a de la partie 18 de la patte en forme d'équerre 14 est raccordée à l'épaulement 15 de la jupe 3 par une surface arrondie 19, tandis que l'extrémité 14a de cette partie 18 de la patte est raccordée à la face intérieure 3a de la jupe 3 par une surface formant un angle droit, dont l'arête 20 est située au niveau de l'épaulement 15. La charnière 10 est par conséquent définie par une mince épaisseur de matière plastique située entre l'arête 20 et la surface arrondie 19.In addition, the external surface 18a of the part 18 of the square-shaped tab 14 is connected to the shoulder 15 of the skirt 3 by a rounded surface 19, while the end 14a of this part 18 of the tab is connected to the inner face 3a of the skirt 3 by a surface forming a right angle, the edge 20 of which is situated at the level of the shoulder 15. The hinge 10 is therefore defined by a thin thickness of plastic material situated between the edge 20 and the rounded surface 19.

Sur les figures 1 et 3, on voit en outre que la surface d'appui 13 ménagée sur le côté de la buse 6 présente des stries 13a et est inclinée vers la jupe 3, l'angle d'inclinaison de cette surface 13 étant de l'ordre de 45°.In FIGS. 1 and 3, it can also be seen that the bearing surface 13 formed on the side of the nozzle 6 has grooves 13a and is inclined towards the skirt 3, the angle of inclination of this surface 13 being of around 45 °.

On va maintenant décrire le fonctionnement du diffuseur conforme à l'invention.We will now describe the operation of the diffuser according to the invention.

Après enlèvement du capuchon 16, lors de la première utilisation du diffuseur 1, l'utilisateur appuie avec son doigt 21 (voir figure 5) sur la surface striée 13 ménagée sur le côté de la buse 6 pour faire pivoter celle-ci dans le sens de la flèche F. Lors de ce mouvement, la buse 3 pivote autour de la charnière 10 qui la relie à la jupe 3 en entraînant la rupture des ponts de garantie 12 qui reliaient la paroi 9 à la jupe 3 à l'opposé de la charnière 10. En poursuivant le pivotement de la buse 6, l'ajutage 7 de celle-ci enfonce la tige 8 à coulissement axial de la valve, ce qui entraîne l'expulsion du produit vers la buse 6, tout en assurant une étanchéité de contact entre l'ajutage 7 et la tige 8 de la valve.After removing the cap 16, during the first use of the diffuser 1, the user presses with his finger 21 (see FIG. 5) on the ribbed surface 13 formed on the side of the nozzle 6 to pivot the latter in the direction of the arrow F. During this movement, the nozzle 3 pivots around the hinge 10 which connects it to the skirt 3 causing the breaking of the guarantee bridges 12 which connected the wall 9 to the skirt 3 opposite the hinge 10. Continuing the pivoting of the nozzle 6, the nozzle 7 of the latter pushes the rod 8 with axial sliding of the valve, which causes the expulsion of the product towards the nozzle 6, while ensuring a tightness of contact between the nozzle 7 and the valve stem 8.

Lors du pivotement de la buse 6 sous l'effet de la pression latérale qu'elle subit, la jupe 3 ne risque pas de fléchir dans le même sens, car elle est fermement calée contre le rebord de la coupelle de montage 4.During the pivoting of the nozzle 6 under the effect of the lateral pressure which it undergoes, the skirt 3 does not risk bending in the same direction, because it is firmly wedged against the edge of the mounting cup 4.

Par ailleurs, étant donné que la surface d'appui 13 se trouve près de la charnière 10, un faible enfoncement de cette surface 13 suffit pour entraîner un enfoncement axial suffisant de la tige 8 pour libérer le produit, de sorte que la sensibilité de la commande de l'ouverture de la valve est notablement accrue.Furthermore, since the bearing surface 13 is located near the hinge 10, a slight depression of this surface 13 is sufficient to cause sufficient axial depression of the rod 8 to release the product, so that the sensitivity of the valve opening control is significantly increased.

De plus, étant donné l'inclinaison de cette surface 13, le doigt 21 de l'utilisateur reste tendu dans une position naturelle, tandis que les autres doigts tiennent le récipient 2, de sorte que l'utilisateur peut parfaitement doser son effort.In addition, given the inclination of this surface 13, the user's finger 21 remains stretched in a natural position, while the other fingers hold the container 2, so that the user can perfectly balance his effort.

Par ailleurs, si l'utilisateur veut accéder à l'espace situé sous la buse 6 et la paroi 9 en forme de disque, il lui suffit de faire pivoter la buse 6, comme indiqué sur la figure 6 dans une direction opposée à la flèche F.Furthermore, if the user wants to access the space located under the nozzle 6 and the wall 9 in the form of a disc, he only has to rotate the nozzle 6, as indicated in FIG. 6 in a direction opposite to the arrow F.

Lors de ce mouvement, la buse 3 pivote autour de la charnière 10. Celle-ci, compte tenu de sa structure et de sa position au niveau de l'épaulement 15, ne risque pas de se déchirer, même si l'utilisateur fait pivoter la buse 6 suivant un angle relativement important.During this movement, the nozzle 3 pivots around the hinge 10. The latter, taking into account its structure and its position at the level of the shoulder 15, is not liable to tear, even if the user pivots the nozzle 6 at a relatively large angle.

Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation que l'on vient de décrire et on peut apporter à celui-ci de nombreuses modifications sans sortir du cadre de l'invention.Of course, the invention is not limited to the embodiment which has just been described and many modifications can be made to it without departing from the scope of the invention.

Ainsi, le diffuseur conforme à l'invention peut s'appliquer à toutes sortes de récipients sous pression, renfermant tout type de produit à diffuser.Thus, the diffuser according to the invention can be applied to all kinds of pressure vessels, containing any type of product to be diffused.
