Le volet 5 coulisse à l'intérieur du capot 1 et se déplace en rotation autour de l'axe de révolution du boîtier, les glissières se prolongeant bien au delà de l'ouverture pour accompagner le volet 5 sur toute sa course.The shutter 5 slides inside the cover 1 and moves in rotation around the axis of revolution of the housing, the slides extending well beyond the opening to accompany the shutter 5 over its entire course.

Selon l'exemple de la figure 4, pour définir deux position stables extrêmes de retenue du volet, volet totalement fermé et volet totalement effacé pour laisser libre l'ouverture, les extrémités de la glissière inférieure 22a et du volet sont pourvues d'un dispositif d'encliquetage 51, 52. Ce dispositif comporte des crochets ressort 51 au niveau du coins inférieurs capot et des butées 52 d'encliquetage des crochets en fin de glissière 22a.According to the example of figure 4 , to define two extreme stable positions for retaining the shutter, shutter completely closed and shutter completely retracted to leave the opening free, the ends of the lower slide 22a and of the shutter are provided with a latching device 51, 52. This device comprises spring hooks 51 at the lower corners of the cover and stops 52 for engaging the hooks at the end of the slideway 22a.

Ce système assure une retenue du capot suffisante pour qu'il ne se déplace pas lors de la manipulation du boîtier mais suffisamment réduite pour permettre de manœuvrer le capot avec un doigt. En outre les crochets ressort et les butées d'encliquetage permettent d'avoir un retour sensitif lors de l'encliquetage et du désencliquetage du capot.
en réalisation alternative, le dispositif d'encliquetage peut être réalisé au niveau du couvercle.This system ensures a sufficient retention of the cover so that it does not move during handling of the housing but sufficiently reduced to allow the cover to be maneuvered with a finger. In addition, the spring hooks and the snap-fastening stops make it possible to have a sensitive return when the cover is snap-in and out.
in an alternative embodiment, the snap-fastening device can be produced at the level of the cover.

En référence aux figures 2 et 4, l'embase est pourvue du dispositif diffuseur axial 4 et d'une partie centrale formant une paroi 23 de section semi-circulaire autour du dispositif diffuseur axial.With reference to figures 2 and 4 , the base is provided with the axial diffuser device 4 and with a central part forming a wall 23 of semi-circular section around the axial diffuser device.

Selon l'exemple de la figure 2, la paroi 23 et une base annulaire 23a la supportant sont reliées à la couronne 21 par au moins une poutre constituée d'une plateforme 25 et de nervures 251, 252. Selon l'exemple représenté, la plateforme 25 est reliée à la base annulaire 23a et les nervures 251, 252 la renforçant sont reliées à la base annulaire et à la paroi 23.According to the example of figure 2 , the wall 23 and an annular base 23a supporting it are connected to the crown 21 by at least one beam consisting of a platform 25 and ribs 251, 252. According to the example shown, the platform 25 is connected to the annular base 23a and the ribs 251, 252 reinforcing it are connected to the annular base and to the wall 23.

En variante selon la figure 6 la plateforme 25 est supprimée et les nervures 253 plus nombreuses réalisent seules la liaison entre la base annulaire 23a supportant la paroi 23 du corps central et la couronne 21.As a variant according to figure 6 the platform 25 is omitted and the more numerous ribs 253 provide only the connection between the annular base 23a supporting the wall 23 of the central body and the crown 21.

Le dispositif diffuseur axial 4 est pour sa part solidaire d'une plaque semi-circulaire 4a qui se prolonge radialement sur environ un quart de sa périphérie par le poussoir 6.The axial diffuser device 4 is for its part integral with a semicircular plate 4a which extends radially over about a quarter of its periphery by the pusher 6.

Le dispositif diffuseur axial est relié, par l'intermédiaire de la plaque 4a à la partie centrale par un ou plusieurs liens souples 24 formant ressort.The axial diffuser device is connected, via the plate 4a to the central part by one or more flexible links 24 forming a spring.

Ainsi, la paroi 23 entoure en partie le diffuseur axial et protège l'intérieur du capot des projections de produit et la couronne 21 entoure et protégeant l'ensemble diffuseur et poussoir de manœuvre sur sa périphérie.Thus, the wall 23 partially surrounds the axial diffuser and protects the interior of the cover from projections of product and the crown 21 surrounds and protects the diffuser and operating push-button assembly on its periphery.

Sur le dessous du capot, en référence à la figure 3, la partie centrale semi-circulaire se prolonge vers le boîtier par une jupe 23a pourvue d'ergots 27 de fixation de l'embase sur un serti 105 autour de la valve du boîtier et représenté en figure 1. Ceci permet d'accrocher solidement le capot sur le boîtier au plus près de la valve.On the underside of the hood, with reference to the figure 3 , the semicircular central part is extended towards the housing by a skirt 23a provided with lugs 27 for fixing the base on a crimp 105 around the valve of the housing and shown in figure 1 . This allows the cover to be securely hung on the housing as close as possible to the valve.

De manière complémentaire ou alternative, la couronne comporte un rebord interne 210 d'encliquetage avec un serti périphérique (110) du boîtier.In a complementary or alternative manner, the crown comprises an internal rim 210 for locking with a peripheral crimp (110) of the case.

Outre la fixation du capot, le fait que la couronne recouvre le haut du boîtier au niveau de son sertissage dôme/corps de boîtier permet d'éviter que la couronne puisse être repoussée vers l'intérieur et empêche de soulever le capot.In addition to fixing the cover, the fact that the crown covers the top of the case at its dome / case body setting prevents the crown from being pushed inwards and prevents the cover from being lifted.

De retour vers le haut du capot, le couvercle 30 comme vu précédemment comporte une paroi annulaire 32 formant une cheminée se terminant en haut du couvercle par l'ouverture axiale 3 et visible notamment en figure 3.Back to the top of the cover, the cover 30 as seen above comprises an annular wall 32 forming a chimney ending at the top of the cover by the axial opening 3 and visible in particular in figure 3 .

Une partie inférieure de cette paroi annulaire 32 rejoint la paroi semi circulaire 23 autour du dispositif diffuseur 4 et représentée en figure 2 en sorte de former un canal anti-projections.A lower part of this annular wall 32 joins the semi-circular wall 23 around the diffuser device 4 and shown in figure 2 so as to form an anti-projections channel.

L'extrémité inférieure de la paroi annulaire 32 entoure la paroi semi circulaire 23, la paroi annulaire et la paroi semi circulaire 23 comportant des moyens d'accrochage mutuels 28, 33 adaptés à solidariser l'embase et le couvercle.The lower end of the annular wall 32 surrounds the semi-circular wall 23, the annular wall and the semi-circular wall 23 comprising mutual hooking means 28, 33 adapted to secure the base and the cover.

Selon l'exemple les moyens d'accrochage 33 de la paroi annulaire sont constitués par une collerette annulaire alors que les moyens d'accrochage sur la paroi semi circulaire 23 sont constitués par des ergots à rampes 28 répartis sur le pourtour de la paroi semi circulaire permettant un encliquetage aisé du couvercle sur l'embase et une retenue efficace de ce couvercle sur l'embase.According to the example, the hooking means 33 of the annular wall are constituted by an annular flange while the hooking means on the semi-circular wall 23 are constituted by lugs with ramps 28 distributed around the periphery of the semi-circular wall allowing a easy snap-in of the cover on the base and effective retention of this cover on the base.

Mieux visibles en figure 6, des nervures 28a se terminant sous les ergots réalisent des butées d'appui de la collerette annulaire 33 pour éviter un enfoncement du couvercle 30 lors par exemple d'un appui fortuit sur ce dernier.Better visible in figure 6 , ribs 28a terminating under the lugs provide abutments for supporting the annular flange 33 to prevent the cover 30 from sinking during, for example, accidental pressing on the latter.

Pour compléter la fixation du couvercle sur l'embase, le bord supérieur de la couronne et le bord inférieur du couvercle sont aussi pourvus de moyen d'encliquetage mutuels 29, 34 adaptés à solidariser l'embase et le couvercle. Ces moyens sous la forme rainures languettes disposés sur le bord supérieur de la couronne 21 et le bord inférieur du couvercle peuvent être complétés par un collage ou un collage ultrason du couvercle et de l'embase.To complete the fixing of the cover on the base, the upper edge of the crown and the lower edge of the cover are also provided with mutual latching means 29, 34 adapted to secure the base and the cover. These means in the form of tongue grooves arranged on the upper edge of the crown 21 and the lower edge of the cover can be supplemented by gluing or ultrasonic gluing of the cover and the base.

Le capot de l'invention, qui n'est pas limité à l'exemple représenté, l'ouverture latérale pouvant notamment être réalisée entièrement dans le couvercle en réduisant la hauteur de la couronne et en augmentant la hauteur de la paroi du couvercle, est aisé à fabriquer, robuste, permet de personnaliser le capot par un choix de couleurs différentes entre les diverses pièces et permet de protéger les doigts de l'utilisateur des éventuelles projection de produit et notamment de peinture dans le cas d'un boîtier aérosol de peinture en bombe.The cover of the invention, which is not limited to the example shown, the lateral opening being able in particular to be produced entirely in the cover by reducing the height of the crown and by increasing the height of the wall of the cover, is easy to manufacture, robust, allows the cover to be personalized by a choice of different colors between the various parts and allows the user's fingers to be protected from any splash of product and in particular paint in the case of an aerosol canister in a bomb.
