Description

RECIPIENT DE PEINTURE COMPORTANT UNE VALVE D'ADMISSION D'AIR OPTIMISEE  PAINT CONTAINER COMPRISING AN OPTIMIZED AIR INTAKE VALVE
La présente invention se rapporte au domaine technique général des récipients contenant des produits liquides à pulvériser et des systèmes, appareils ou dispositifs de pulvérisation. Les récipients sont en général utilisés pour le conditionnement, la préparation et le travail avec un pistolet de peinture ou de pulvérisation, le stockage, l'application et l'éventuelle conservation d'un produit issu d'un mélange d'au moins deux composants. The present invention relates to the general technical field of containers containing liquid spray products and systems, apparatus or devices for spraying. The containers are generally used for packaging, preparing and working with a spray gun or spraying, storage, application and possible preservation of a product from a mixture of at least two components .
Plus particulièrement, l'invention se rapporte à un nécessaire ou à un kit jetable contenant de façon séparée les deux ou plusieurs composants à mélanger avant son utilisation après son montage par l'intermédiaire d'une pièce d'adaptation sur un pistolet à peindre.  More particularly, the invention relates to a kit or a disposable kit separately containing the two or more components to be mixed before use after its assembly via an adapter part on a spray gun.
Dans le domaine des produits bi-composants et plus généralement des produits pluri-composants à peindre, à projeter ou à pulvériser, par exemple les peintures, les apprêts, les vernis et autres, chacun des deux ou plusieurs composants du produit final doit être conditionné à part. Ces composants sont mélangés au dernier moment, juste avant d'être utilisés, car au bout d'un certain temps il n'est plus possible de les projeter ou de les pulvériser, par exemple du fait qu'ils prennent en masse, qu'ils durcissent ou qu'ils deviennent pâteux. En outre, ces composants sont généralement sensibles à l'air et/ou à la lumière et doivent être conditionnés séparément dans des contenants étanches et/ou opaques.  In the field of two-component products and more generally multi-component products for painting, spraying or spraying, for example paints, primers, varnishes and the like, each of the two or more components of the final product must be conditioned. apart. These components are mixed at the last moment, just before being used, because after a certain time it is no longer possible to spray them or to spray them, for example because they take in mass, that they harden or become pasty. In addition, these components are generally sensitive to air and / or light and must be packaged separately in sealed and / or opaque containers.
Lorsqu'un produit bi-composant ou pluri-composant doit être pulvérisé, l'opérateur doit généralement effectuer lui-même le mélange préalable des composants du produit avant de transférer ce mélange dans un récipient adapté à son outil de pulvérisation, chacun des composants du produit est alors initialement conditionné individuellement dans un contenant à part.  When a bi-component or multi-component product is to be sprayed, the operator must generally pre-mix the components of the product before transferring the mixture to a suitable container for its spray tool, each of the components of the The product is then initially individually packaged in a separate container.
Cette préparation des produits bi-composants ou pluri- composants à pulvériser présente de nombreux désavantages, parmi lesquels on peut notamment citer :  This preparation of two-component or multi-component spraying products has many disadvantages, among which we can notably mention:
• conditionnement commercial volumineux et coûteux pour le produit bi-composant car chacun des composants doit être conditionné individuellement dans un contenant à part ; • bulky and expensive commercial packaging for the bi-component product because each of the components must be individually packaged in a separate container;
• risques de renversement et de pertes en composants ou en produit lors de la préparation du produit à pulvériser en raison des multiples opérations de transfert d'un récipient dans un autre  • risks of overturning and loss of components or product during the preparation of the product to be sprayed due to multiple operations of transfer from one container to another
• risques de mauvais dosage de la part de l'opérateur lors de la préparation du produit à pulvériser, qui peut nuire à l'efficacité du produit bi-composant obtenu ; • risk of improper dosage from the operator during the preparation of the product to be sprayed, which can affect the effectiveness of the bi-component product obtained;
· stockage encombrant de contenants partiellement vidés pour chacun des composants après mélange,  · Cumbersome storage of partially emptied containers for each of the components after mixing,
• détérioration à l'air des composants restants stockés dans les contenants partiellement vidés ;  • air deterioration of remaining components stored in partially emptied containers;
• temps de préparation nécessaire lors du mélange des composants alors que le coût de plus en plus élevé de la main d'œuvre amène les employeurs à trouver des solutions permettant d'augmenter la rapidité des interventions.  • the preparation time required when mixing components, while the rising cost of labor forces employers to find solutions to increase the speed of interventions.
Dans le domaine de la peinture ou de la pulvérisation au moyen d'un outil du type pistolet à gravité, à succion ou similaire, il n'existe que peu de conditionnements bi-composants à usage unique.  In the field of painting or spraying by means of a tool such as a gravity gun, a suction gun or the like, there are only a few single-use two-component packages.
Afin de rendre le travail de peinture ou de pulvérisation plus facile et plus rapide mais aussi plus économique en produits et en matériel, la présente invention a pour but de fournir un nouveau récipient de conditionnement et de travail servant de godet jetable à monter sur un outil de pulvérisation.  In order to make the painting or spraying work easier and faster but also more economical in products and materials, the present invention aims to provide a new packaging and working container as a disposable cup for mounting on a tool. spray.
Un autre objet de l'invention vise à améliorer l'extraction par exemple par gravité du composant liquide contenu dans un récipient servant de godet ou de réservoir de pulvérisation.  Another object of the invention is to improve the extraction for example by gravity of the liquid component contained in a container serving as a bucket or spray tank.
Les objets assignés à l'invention sont atteints à l'aide d'un récipient jetable, destiné à contenir au moins un composant liquide à pulvériser et présentant un fond, au moins une paroi latérale périphérique s'étendant à partir du fond jusqu'à une extrémité ouverte espacée et en regard dudit fond, lequel est pourvu d'un dispositif d'évent obturable, caractérisé en ce que le dispositif d'évent obturable comprend une ouverture formant un passage d'air, ménagée dans le fond et une valve rotative montée sur une face externe dudit fond dans le prolongement de l'ouverture, pour obturer et pour libérer le passage d'air. The objects assigned to the invention are achieved by means of a disposable container, intended to contain at least one liquid component to be sprayed and having a bottom, at least one peripheral lateral wall extending from the bottom to an open end spaced and facing said bottom, which is provided with a closable vent device, characterized in that the closable vent device comprises an opening forming an air passage, formed in the bottom and a rotary valve mounted on an outer face of said bottom in the extension of the opening, to seal and to release the passage of air.
Selon un exemple de réalisation du récipient conforme à l'invention, la valve rotative présente un axe de rotation s'étendant dans un plan parallèle à la face externe, monté en ajustement serré dans des mâchoires solidaires de et en saillie sur ladite face externe du fond.  According to an exemplary embodiment of the container according to the invention, the rotary valve has an axis of rotation extending in a plane parallel to the outer face, mounted in close fit in jaws integral with and projecting on said outer face of background.
Selon un exemple de réalisation du récipient conforme à l'invention, la valve rotative comporte un levier d'actionnement mobile en rotation entre deux positions en butée constituant des fins de course, et correspondant respectivement à une libération et à une obturation de l'ouverture.  According to an exemplary embodiment of the container according to the invention, the rotary valve comprises an actuating lever movable in rotation between two abutting positions constituting limit switches, respectively corresponding to a release and a closure of the opening .
Selon un exemple de réalisation du récipient conforme à l'invention, le levier d'actionnement, lorsque la valve rotative est en position ouverte, s'étend en saillie sur la face externe du fond et dépasse les autres parties du fond également en saillie sur ladite face externe.  According to an exemplary embodiment of the container according to the invention, the actuating lever, when the rotary valve is in the open position, protrudes on the outer face of the bottom and protrudes from the other parts of the bottom also projecting on said outer face.

Description détaillée detailed description
La figure 1 illustre selon une vue en perspective un exemple de réalisation d'un récipient 1 conforme à l'invention. Ce récipient de forme générale sensiblement cylindrique ou tronconique présente une paroi latérale périphérique 2 s'étendant à partir d'un fond 3 jusqu'à une extrémité ouverte 4. Cette dernière est visible plus précisément à la figure 2.  Figure 1 illustrates in perspective view an embodiment of a container 1 according to the invention. This generally cylindrical or frustoconical generally shaped container has a peripheral side wall 2 extending from a bottom 3 to an open end 4. The latter is visible more precisely in FIG.
La figure 2 montre par exemple une réalisation du récipient 1 pourvu d'un compartiment interne délimité par un tube 1 a interne. L'extrémité ouverture 4, appelée aussi extrémité de connexion est avantageusement obturée par un film de scellement 5 lorsque le récipient 1 est remplit par un ou plusieurs produits.  FIG. 2 shows, for example, an embodiment of the container 1 provided with an internal compartment delimited by an internal tube 1. The opening end 4, also called connection end is advantageously closed by a sealing film 5 when the container 1 is filled with one or more products.
Le film de scellement 5 est représenté, non rapporté sur le récipient 1 , à la figure 3 en vue de dessus. Le film de scellement 5 présente une ou plusieurs languettes de préhension 5a accessibles à sa périphérie de manière à permettre une meilleure préhension lors de sa désolidarisation du récipient 1 .  The sealing film 5 is shown, not attached to the container 1, in Figure 3 in plan view. The sealing film 5 has one or more gripping tabs 5a accessible at its periphery so as to allow a better grip when it is detached from the container 1.
Le récipient 1 est également pourvu, de façon centrée ou décentrée, sur une face externe 3a du fond 3 d'un dispositif d'évent obturable 6. Ce dernier est représenté respectivement fermé et ouvert par exemple aux figures 1 et 3.  The container 1 is also provided, centrally or eccentrically, on an outer face 3a of the bottom 3 of a closable vent device 6. The latter is shown respectively closed and open for example in Figures 1 and 3.
Le dispositif d'évent obturable 6 comprend une ouverture The closable vent device 6 includes an opening
7 ménagé dans le fond 3 de manière à former un passage d'air. Cette ouverture 7 est illustrée notamment aux figures 9, 1 1 , 12 et 13. 7 formed in the bottom 3 so as to form an air passage. This opening 7 is illustrated in particular in FIGS. 9, 11, 12 and 13.
Le dispositif d'évent obturable 6 comprend également une valve rotative 8 dont un premier mode de réalisation est illustré plus en détails aux figures 4 et 5 et dont un second mode de réalisation est illustré plus en détails aux figures 6 à 8. La valve rotative 8 est montée sur une face externe 3a du fond 3 et ce dans le prolongement de l'ouverture 7. On pourra se reporter plus particulièrement aux figures 9, 1 1 , 12 et 13. The closable vent device 6 also comprises a rotary valve 8, a first embodiment of which is illustrated 4 and 5 and a second embodiment of which is illustrated in greater detail in FIGS. 6 to 8. The rotary valve 8 is mounted on an outer face 3a of the bottom 3 and in the extension of the opening 7 Referring more particularly to Figures 9, 11, 12 and 13.
La valve rotative 8 présente un axe de rotation 8a s'étendant dans un plan parallèle à la face externe 3a et monté en ajustement serré dans des mâchoires 9. Les mâchoires 9 sont avantageusement solidaires et en saillie sur la face externe 3a.  The rotary valve 8 has an axis of rotation 8a extending in a plane parallel to the outer face 3a and mounted in tight fit in the jaws 9. The jaws 9 are preferably integral and projecting on the outer face 3a.
La valve rotative 8 comporte avantageusement un levier d'actionnement 8b pour déplacer ladite valve rotative 8 entre deux positions en butée constituant des fins de course. Ces deux positions en butée correspondent respectivement à une libération et à une obturation de l'ouverture 7.  The rotary valve 8 advantageously comprises an actuating lever 8b for moving said rotary valve 8 between two abutting positions constituting limit switches. These two abutment positions respectively correspond to a release and a closure of the opening 7.
La valve rotative 8 comporte également une partie cylindrique centrale 8c. Cette dernière est en contact avec la face externe 3a du fond 3 et se termine longitudinalement et axialement de chaque côté par une extrémité coaxiale du plus petit diamètre pour constituer l'axe de rotation 8a engagé dans une mâchoire 9 correspondante.  The rotary valve 8 also has a central cylindrical portion 8c. The latter is in contact with the outer face 3a of the bottom 3 and ends longitudinally and axially on each side by a coaxial end of the smaller diameter to form the axis of rotation 8a engaged in a corresponding jaw 9.
Selon un premier mode de réalisation de la valve rotative 8, la partie cylindrique 8c présente par ailleurs un conduit 8d radial et traversant pour permettre, en fonction de la position en rotation de la valve rotative 8, de libérer le passage d'air en mettant en communication l'ouverture 7 avec l'air libre ou d'obturer ladite ouverture 7. Une telle valve rotative 8 est représentée sur les figures 4 et 5.  According to a first embodiment of the rotary valve 8, the cylindrical portion 8c also has a radial duct 8d and through to allow, depending on the rotational position of the rotary valve 8, to release the air passage by putting communicating the opening 7 with the free air or closing said opening 7. Such a rotary valve 8 is shown in Figures 4 and 5.
Selon un second mode de réalisation de la valve rotative 8, la partie cylindrique 8c comprend une gorge 8e ouverte vers l'extérieur, par exemple présente sur un quart de tour de la partie cylindrique 8c, pour permettre, en fonction de la position en rotation de la valve rotative 8, de libérer le passage d'air en mettant en communication l'ouverture 7 avec l'air libre ou d'obturer ladite ouverture 7. Une telle valve rotative 8 est représentée sur les figures 6 à 8.  According to a second embodiment of the rotary valve 8, the cylindrical portion 8c comprises a groove 8e open towards the outside, for example present on a quarter turn of the cylindrical portion 8c, to allow, depending on the rotational position of the rotary valve 8, to release the air passage by placing the opening 7 in communication with the free air or to close off said opening 7. Such a rotary valve 8 is shown in FIGS. 6 to 8.
La valve rotative 8 selon le premier mode de réalisation est ainsi illustrée en position ouverte par exemple à la figure 9 et en position fermée par exemple à la figure 1 1 , 12 ou 13. The rotary valve 8 according to the first embodiment is thus illustrated in the open position for example in Figure 9 and in the closed position for example in Figure 1 1, 12 or 13.
Le récipient 1 et les mâchoires 9 sont avantageusement réalisés en une seule pièce, par exemple par injection d'un matériau plastique.  The container 1 and the jaws 9 are advantageously made in one piece, for example by injection of a plastic material.
L'axe de rotation 8a et la partie cylindrique 8c sont avantageusement réalisés en une seule pièce, par exemple par injection d'un matériau plastique.  The axis of rotation 8a and the cylindrical portion 8c are advantageously made in one piece, for example by injection of a plastic material.
Le récipient 1 conforme à l'invention, illustré par exemple à la figure 1 est pré-rempli avec au moins un produit du genre peinture, vernis ou produit de nettoyage et comporte un élément de fermeture qui est avantageusement constituée par le film de scellement 5.  The container 1 according to the invention, illustrated for example in Figure 1 is pre-filled with at least one product of the paint, varnish or cleaning product type and comprises a closure element which is advantageously constituted by the sealing film 5 .
Un exemple de réalisation du récipient 1 conforme à l'invention illustré aux figures 2, 9, 10, 1 1 , 12, 14 et 17, concerne un récipient 1 bi-composant, destiné à contenir de façon séparée et isolée deux composants distincts. Ces derniers seront mélangés avant une opération de pulvérisation.  An exemplary embodiment of the container 1 according to the invention illustrated in Figures 2, 9, 10, 1 1, 12, 14 and 17 relates to a bicomponent container 1 for separately and separately contain two separate components. These will be mixed before a spraying operation.
Ainsi, comme on peut le voir par exemple à la figure 2, le récipient 1 comporte intérieurement le tube 1 a dont l'extrémité inférieure 1 c est engagée dans une rainure 10, par exemple circulaire et de section transversale rectangulaire, ménagée dans le fond 3. L'extrémité supérieure du tube 1 a est avantageusement pourvue d'un méplat 1 b périphérique pour faciliter l'adhésion du film de scellement 5. On pourra se reporter plus particulièrement à la figure 1 1 .  Thus, as can be seen for example in FIG. 2, the container 1 internally comprises the tube 1a whose lower end 1c is engaged in a groove 10, for example circular and of rectangular cross section, formed in the bottom 3. The upper end of the tube 1a is advantageously provided with a flat part 1b peripheral to facilitate the adhesion of the sealing film 5. Reference will be made more particularly to Figure 1 1.
La rainure 10 est donc constituée par une forme en U du fond 3, par exemple avec une forme conique radiale du côté intérieur ou extérieur pour assurer ou améliorer l'étanchéité. Selon d'autres exemples de réalisation, l'étanchéité peut être obtenue radialement que d'un côté, des lèvres d'étanchéité, des ergots pour réaliser un encliquetage, emboîtement ou enchâssement élastique (engagement serré avec éléments de retenue) ou autres éléments rapportés d'étanchéité peuvent être prévus, le cas échéant en matériaux différents.  The groove 10 is constituted by a U-shaped bottom 3, for example with a radial conical shape on the inner or outer side to ensure or improve the seal. According to other exemplary embodiments, the seal may be obtained radially on one side, sealing lips, lugs for snap-fitting, interlocking or elastic recess (tight engagement with retaining elements) or other inserts. may be provided, if necessary in different materials.
Des nervures de guidage axiaux peuvent également être prévus sur le tube 1 a interne ou dans la rainure avec une étanchéité axiale en fond de rainure Axial guide ribs may also be provided on the inner tube 1 or in the groove with a seal axial groove bottom
Le champ supérieur 2a de la paroi latérale 2 présente avantageusement une surface de contact inférieure à la surface de contact que présente le méplat 1 b. Ceci permet d'obtenir une adhésion plus forte entre le film de scellement 5 et le tube 1 a qu'entre le film de scellement 5 et le champ supérieur 2a du récipient 1 . Il est ainsi plus facile d'extraire le tube 1 a du récipient 1 , plus précisément de son engagement étanche dans la rainure 10 du fond 3, en exerçant une traction sur le film de scellement 5, le tube 1 a restant alors accroché au dit film de scellement 5. Ceci est illustré par exemple à la figure 12.  The upper field 2a of the side wall 2 advantageously has a contact surface smaller than the contact surface that the flat 1b has. This makes it possible to obtain a stronger adhesion between the sealing film 5 and the tube 1a than between the sealing film 5 and the upper field 2a of the container 1. It is thus easier to extract the tube 1a from the container 1, more precisely from its sealed engagement in the groove 10 of the bottom 3, by exerting a pull on the sealing film 5, the tube 1 then remaining attached to the said sealing film 5. This is illustrated for example in Figure 12.
La figure 13 illustre un exemple de réalisation du récipient 1 conforme à l'invention lequel est destiné à ne contenir qu'un seul composant. Il n'y a donc aucun tube 1 a et aucune paroi de séparation disposé(e) à l'intérieur du récipient 1 ou engagé(e) dans la rainure 10.  Figure 13 illustrates an embodiment of the container 1 according to the invention which is intended to contain only one component. There is therefore no tube 1a and no partition wall disposed inside the container 1 or engaged in the groove 10.
La figure 14 illustre un exemple de réalisation d'un récipient 1 bi-composants conforme à l'invention. Il convient d'extraire le tube 1 a intérieur de façon à pouvoir mélanger les composants stockés respectivement à l'intérieur dudit tube 1 a et périphériquement dans le récipient 1 autour dudit tube 1 a. Ce dernier peut aussi être décentré dans le récipient 1 .  FIG. 14 illustrates an exemplary embodiment of a two-component container 1 according to the invention. It is necessary to extract the tube 1 inside so as to be able to mix the components stored respectively inside said tube 1 a and peripherally in the container 1 around said tube 1 a. The latter can also be off-center in the container 1.
Le récipient 1 est de préférence constitué d'une matière plastique translucide ou opaque en fonction de la nature du ou des produits contenus, lesquels peuvent être sensible à la lumière, notamment aux rayonnements ultraviolets.  The container 1 is preferably made of a translucent or opaque plastic depending on the nature of the contained product or products, which may be sensitive to light, especially ultraviolet radiation.
Il peut être intéressant d'utiliser une tige d'agitation 12 creuse, illustrée aux figures 14 et 15 laquelle présente un épaulement 12a sous forme de bord d'attaque à l'une de ses extrémités ainsi que des crans de positionnement 12b à son autre extrémité. Il peut ainsi être utile d'engager l'épaulement 12a sous le méplat 1 b du tube 1 a intérieur en prenant appui avec la tige 12, notamment à l'aide de l'un des crans 12b, sur le champ supérieur 2a. On utilise ainsi un effet de levier pour soulever et extraire le tube 1 a du récipient 1 ou pour amorcer son extraction hors de la rainure 10.  It may be advantageous to use a hollow stirring rod 12, illustrated in FIGS. 14 and 15, which has a shoulder 12a in the form of a leading edge at one of its ends as well as positioning notches 12b at its other end. end. It may thus be useful to engage the shoulder 12a under the flat part 1b of the tube 1 inside by bearing with the rod 12, in particular with the aid of one of the notches 12b, on the upper field 2a. A lever effect is thus used to lift and extract the tube 1a from the container 1 or to start its extraction out of the groove 10.
Une fois ce tube 1 a intérieur extrait du récipient 1 , il est indiqué de mélanger les deux composants à l'intérieur dudit récipient 1 à l'aide de la tige d'agitation 12. Cette dernière est pourvue à cet effet de trous 12c facilitant l'opération de mélange. Once this tube 1 inside extracted from the container 1, it is indicated to mix the two components inside said container 1 with the stirring rod 12. The latter is provided for this purpose with holes 12c facilitating the mixing operation.
Le récipient 1 est avantageusement pourvu de portions de nervures hélicoïdale 13 sur le côté supérieur et extérieur de la paroi latérale périphérique 2 de manière à constituer un moyen de connexion à un pistolet de pulvérisation 14. Une telle connexion, connue en tant que telle, se fait par l'intermédiaire d'un couvercle 15 pourvu d'un orifice de sortie associé à un adaptateur. Le couvercle 15 comporte intérieurement des moyens de montage complémentaires aux portions de nervures 13 pour être monté ou vissé sur le récipient 1 . L'adaptateur monté sur l'orifice de sortie permet de connecter le réservoir ainsi constitué sur le pistolet de pulvérisation 14. Un filtre 16 est de préférence intégré au couvercle 15.  The container 1 is advantageously provided with portions of helical ribs 13 on the upper and outer side of the peripheral side wall 2 so as to constitute a means of connection to a spray gun 14. Such a connection, known as such, is made via a cover 15 provided with an outlet port associated with an adapter. The lid 15 internally comprises complementary mounting means to the rib portions 13 to be mounted or screwed on the container 1. The adapter mounted on the outlet orifice makes it possible to connect the tank thus constituted on the spray gun 14. A filter 16 is preferably integrated in the lid 15.
Le réservoir comprenant le récipient 1 et le couvercle 15 selon l'invention, destiné à être monté sur un outil de peinture ou de pulvérisation, par exemple un pistolet de pulvérisation 14.  The reservoir comprising the container 1 and the lid 15 according to the invention, intended to be mounted on a painting or spraying tool, for example a spray gun 14.
La présente description porte principalement sur le cas d'un produit bi-composant ou mono-composant. L'augmentation du nombre des composants se traduit par la multiplication relative de volumes supplémentaires individuels contenant chacun de ceux-ci dans le récipient 1 .  The present description is mainly concerned with the case of a two-component or one-component product. The increase in the number of components results in the relative multiplication of individual additional volumes containing each of these in the container 1.
Si le produit final utilisé après mélange pour pulvériser ou projeter est par exemple une peinture, un apprêt, un revêtement ou un vernis, le premier composant peut être un solvant ou un liant et le second composant une charge ou un durcisseur.  If the final product used after mixing for spraying or spraying is for example a paint, a primer, a coating or a varnish, the first component may be a solvent or a binder and the second component a filler or a hardener.
Le couvercle 15 présente avantageusement une pièce ou partie d'adaptation ou adaptateur prévue pour connecter l'ensemble le réservoir de l'invention à un outil de pulvérisation. Dans le cas où l'ensemble jetable 1 de l'invention est prévu pour être monté sur un pistolet de pulvérisation 14 notamment à gravité, la pièce ou partie d'adaptation comporte un cône de distribution ou une forme technique particulière d'adaptation à l'entrée du pistolet 14 tel que représenté notamment sur la figure 16. L'ensemble, appelé aussi réservoir, comprenant le récipient 1 et le couvercle 15, constitue ainsi un véritable godet complet qui est jetable. Le récipient 1 , illustré par exemple à la figure 17, comporte de renforts 17 solidaires du fond 3 et d'une partie 10a en saillie sur la face externe 3a, délimitant la rainure 10. Les renforts 17, par exemple au nombre de trois, présentent une forme en triangle et sont répartis sensiblement en étoile le long de la partie 10a. Les renforts 17 s'étendent également de part et d'autre de la partie 10a d'extension circulaire. Les renforts 17 contribuent ainsi à limiter ou supprimer les déformations du fond 3, notamment lors de l'opération d'obturation ou de scellage du récipient 1 , au cours de laquelle ledit récipient est soumis à un certain nombre de contraintes mécaniques. The cover 15 advantageously has a part or adapter part or adapter provided for connecting the assembly of the reservoir of the invention to a spraying tool. In the case where the disposable assembly 1 of the invention is intended to be mounted on a spray gun 14 including gravity, the part or adaptation part comprises a distribution cone or a particular technical form of adaptation to the the entry of the gun 14 as shown in particular in Figure 16. The assembly, also called tank, comprising the container 1 and the lid 15, thus constitutes a true full bucket which is disposable. The container 1, illustrated for example in Figure 17, comprises reinforcements 17 integral with the bottom 3 and a portion 10a projecting on the outer face 3a, defining the groove 10. The reinforcements 17, for example three in number, have a triangular shape and are substantially distributed in a star along the portion 10a. The reinforcements 17 also extend on either side of the portion 10a of circular extension. The reinforcements 17 thus contribute to limiting or eliminating the deformations of the bottom 3, in particular during the sealing or sealing operation of the container 1, during which said container is subjected to a certain number of mechanical stresses.
De manière évidente, l'invention ne se limite pas aux modes de réalisation préférentiels décrits précédemment et représentés sur les différentes figures, l'homme du métier pouvant y apporter de nombreuses modifications et imaginer d'autres variantes sans sortir ni de la portée, ni du cadre de l'invention.  Obviously, the invention is not limited to the preferred embodiments described above and shown in the various figures, the skilled person can make many modifications and imagine other variants without departing from the scope and of the scope of the invention.
