Description

"Procédé de fabrication d'un emballage métallique tel
que notamment un seau à peinture et emballage
correspondant"
L'invention se rapporte à un procédé de fabrication d'un emballage métallique plus particulièrement destiné à contenir une peinture, un vernis ou tout autre produit liquide nécessitant d'être réhomogénéisé avant utilisation."Method of manufacturing a metallic packaging such
including a paint bucket and packaging
corresponding"
The invention relates to a method of manufacturing a metallic packaging more particularly intended to contain a paint, a varnish or any other liquid product which needs to be rehomogenized before use.

L'invention concerne aussi un emballage métallique conformé pour permettre l'adaptation d'un agitateur ou malaxeur, connu en soi. The invention also relates to a metallic packaging shaped to allow the adaptation of an agitator or kneader, known per se.

Dans de nombreux domaines techniques on rencontre de petites installations d'application de peinture ou vernis. C'est le cas notamment dans une entreprise de réparation de carrosserie. On utilise alors des quantités limitées de produit de revêtement, généralement comprises entre 1 et 5 litres pour une même couleur, suivant l'importance des travaux à effectuer. In many technical fields there are small installations for applying paint or varnish. This is particularly the case in a body repair business. Limited quantities of coating product are then used, generally between 1 and 5 liters for the same color, depending on the importance of the work to be carried out.

Les produits de revêtement sont donc conditionnés dans des seaux métalliques dimensionnés en fonction des besoins, c'est-à-dire ayant une contenance de 1 à quelques litres. Les utilisateurs ont souvent à leur disposition des malaxeurs permettant de réhomogénéiser le produit de revêtement avant utilisation. Un tel malaxeur est composé d'une sorte de couvercle venant s'adapter sur l'ouverture du seau et d'un arbre à ailettes, ou analogue, monté tournant-au centre dudit couvercle, perpendiculairement à celui-ci. L'arbre peut être entraîné par un moteur électrique. Pour un bon fonctionnement, il est nécessaire que le couvercle du malaxeur soit bien fixé au seau métallique contenant le produit de revêtement. Pour ce faire, il est muni d'organes de blocage venant coopérer avec les bords du seau.Chaque organe de blocage est formé par un axe monté tournant dans le couvercle et muni à son extrémité d'un excentrique susceptible de venir se bloquer contre la face interne du rebord de l'ouverture. Pour obtenir une bonne étanchéité, il est nécessaire de réaliser une surface de contact suffisante entre ledit couvercle du malaxeur et le bord de l'ouverture ainsi qu'un serrage efficace de ce couvercle, grâce à l'action des organes de blocage décrits ci-dessus. Dans ce but, un seau de peinture connu est muni, au niveau de son ouverture, d'une bague annulaire de forme assez complexe qui augmente le coût de fabrication de l'emballage métallique. L'invention permet de résoudre ce problème.The coating products are therefore packaged in metal buckets sized according to requirements, that is to say having a capacity of 1 to a few liters. Users often have mixers at their disposal to rehomogenize the coating product before use. Such a mixer is composed of a kind of cover which fits over the opening of the bucket and of a fin shaft, or the like, mounted to rotate in the center of said cover, perpendicularly to the latter. The shaft can be driven by an electric motor. For proper operation, the mixer cover must be securely attached to the metal bucket containing the coating material. To do this, it is provided with blocking members which cooperate with the edges of the bucket. Each blocking member is formed by a pin mounted rotating in the cover and provided at its end with an eccentric capable of coming to block against the internal face of the rim of the opening. To obtain a good seal, it is necessary to provide a sufficient contact surface between said mixer cover and the edge of the opening as well as effective tightening of this cover, thanks to the action of the locking members described above. above. For this purpose, a known bucket of paint is provided, at its opening, with an annular ring of rather complex shape which increases the cost of manufacturing the metal packaging. The invention solves this problem.

Dans ce but, l'invention concerne un procédé de fabrication d'un emballage métallique comportant une ouverture dégageant sensiblement la totalité d'une extrémité d'un corps de boîte, caractérisé en ce qu'il consiste à pratiquer une moulure interne dans la paroi du corps de boite au voisinage de ladite extrémité, approximativement dans un plan perpendiculaire à l'axe dudit corps de boîte et à écraser axialement ladite moulure pour obtenir un rebord annulaire interne, axialement en retrait de l'ouverture. To this end, the invention relates to a method of manufacturing a metal package comprising an opening which substantially releases all of one end of a box body, characterized in that it consists in making an internal molding in the wall of the box body in the vicinity of said end, approximately in a plane perpendicular to the axis of said box body and to axially crush said molding to obtain an internal annular rim, axially set back from the opening.

Ce rebord annulaire permet le serrage des organes de blocage décrits plus haut. Il est distinct de la bague métallique habituelle délimitant l'ouverture du seau. Ce rebord est relativement facile à fabriquer pendant l'élaboration du corps de boite et le profil du bord de 1 'ouverture peut être en contrepartie notablement simplifié. Il peut notamment être réalisé par un simple roulé de l'extrémité du corps de boite accompagné d'un moulurage, sans qu'il soit nécessaire d'y sertir une bague. This annular rim allows the tightening of the locking members described above. It is distinct from the usual metal ring delimiting the opening of the bucket. This rim is relatively easy to manufacture during the development of the box body and the profile of the edge of one opening can be significantly simplified in return. It can in particular be produced by a simple roll of the end of the box body accompanied by a molding, without it being necessary to crimp a ring there.

L'invention concerne donc aussi un emballage métallique du type comportant un corps de boite ayant une ouverture dégageant sensiblement la totalité de l'une de ses extrémités, caractérisé en ce qu'il comporte un rebord annulaire plat défini par une moulure circonférentielle aplatie de la paroi latérale du corps de boîte, au voisinage de ladite ouverture et en retrait, axialement, par rapport à celle-ci. The invention therefore also relates to a metallic packaging of the type comprising a box body having an opening which releases substantially all of one of its ends, characterized in that it comprises a flat annular rim defined by a flattened circumferential molding of the side wall of the box body, in the vicinity of said opening and recessed, axially, with respect thereto.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre, d'un procédé de fabrication d'un emballage métallique conforme à son principe et d'un emballage obtenu par ce procédé, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels:
- les figures la-ld décrivent les principales phases caractéristiques du procédé; et
- la figure 2 est une vue partielle en coupe et à plus grande échelle de l'emballage obtenu par la mise en oeuvre de ce procédé, une partie d'un malaxeur connu en soi étant également représentée en place sur cet emballage.The invention will be better understood and other advantages thereof will appear more clearly in the light of the description which follows, of a process for manufacturing a metal packaging conforming to its principle and of a packaging obtained by this process, given solely by way of example and made with reference to the appended drawings in which:
- Figures la-ld describe the main characteristic phases of the process; and
- Figure 2 is a partial sectional view on a larger scale of the packaging obtained by the implementation of this method, part of a kneader known per se also being shown in place on this packaging.

En se reportant plus particulièrement aux figures la-ld, on a illustré les principales phases du procédé aboutissant à la formation d'un rebord interne en retrait de l'ouverture. Le corps de boîte 12, sensiblement tubulaire et cylindrique, est obtenu de façon classique en roulant un flan rectangulaire sur lui-même et en pratiquant une soudure longitudinale des deux bords opposés rejoints. Ces opérations classiques n'ont pas été représentées. C'est sur ce corps de boîte 12 que sont effectuées les opérations spécifiques de l'invention. Il s'agit d'abord d'un moulurage (figures la-lc) à des profondeurs progressivement croissantes, effectué sur plusieurs rotations du corps de boîte. Ce moulurage est obtenu à partir d'une ou plusieurs molettes 15a, 15b, 15c, dont l'axe de rotation est parallèle à l'axe y'y du corps de boite.On provoque ainsi un étirement du métal sur une zone annulaire du corps de boîte, à peu de distance d'une extrémité 16 de celui-ci, destinée à former la future ouverture du seau. On obtient une moulure interne 17a, 17b, 17c, de plus en plus profonde, s'étendant approximativement dans un plan perpendiculaire à l'axe y'y du corps de boîte. Referring more particularly to FIGS. 1a-1d, the main phases of the method have been illustrated, leading to the formation of an internal rim set back from the opening. The box body 12, substantially tubular and cylindrical, is obtained in a conventional manner by rolling a rectangular blank on itself and by practicing a longitudinal weld of the two opposite edges joined. These conventional operations have not been shown. It is on this box body 12 that the specific operations of the invention are carried out. It is first of all a molding (figures la-lc) at progressively increasing depths, carried out on several rotations of the box body. This molding is obtained from one or more knurls 15a, 15b, 15c, the axis of rotation of which is parallel to the axis y'y of the box body. This thus causes the metal to stretch over an annular zone of the box body, a short distance from one end 16 thereof, intended to form the future opening of the bucket. An internal molding 17a, 17b, 17c is obtained, increasingly deep, extending approximately in a plane perpendicular to the axis y'y of the box body.

L'opération suivante consiste à écraser axialement la moulure 17c pour obtenir un rebord annulaire 19 aussi plat que possible. C'est l'opération illustrée à la figure ld. Cette opération est effectuée à l'aide d'un outillage formant marteau et enclume 20a, 206. Le marteau et l'enclume sont placés axialement de part et d'autre de la moulure, à l'intérieur du corps de boîte et un soutien extérieur est assuré par une bague cylindrique 21 pour éliminer toute déformation du corps de boîte pendant cette opération. Le rebord annulaire 19, axialement en retrait par rapport à la future ouverture, permettra la fixation du couvercle du malaxeur, comme on le verra plus loin.The following operation consists in axially crushing the molding 17c in order to obtain an annular flange 19 as flat as possible. This is the operation illustrated in Figure ld. This operation is carried out using a tool forming a hammer and anvil 20a, 206. The hammer and anvil are placed axially on either side of the molding, inside the box body and a support. outside is provided by a cylindrical ring 21 to eliminate any deformation of the box body during this operation. The annular rim 19, axially set back relative to the future opening, will allow the fixing of the mixer cover, as will be seen below.

Le procédé d'élaboration du seau est poursuivi par des opérations classiques en elles-mêmes, pour terminer l'ouverture dudit seau. Ces opérations ne sont pas représentées en détail; elles consistent principalement à pratiquer une nouvelle moulure interne 22, peu profonde, au-dessus du rebord annulaire 19 et un roulé externe 23 dont le profil particulier est visible sur la figure 2, pour définir la bordure de l'ouverture du seau. La moulure 22 permet l'adaptation du couvercle du seau, par emboîtement élastique étanche. Au moment de l'utilisation du produit de revêtement, le malaxeur 25 est mis en place en lieu et place du couvercle du seau. The process of making the bucket is continued by conventional operations in themselves, to complete the opening of said bucket. These operations are not shown in detail; they mainly consist in making a new shallow internal molding 22 above the annular rim 19 and an external roll 23 whose particular profile is visible in FIG. 2, to define the border of the opening of the bucket. The molding 22 allows the adaptation of the cover of the bucket, by tight elastic fitting. When using the coating product, the mixer 25 is placed in place of the bucket lid.

Ce malaxeur comporte lui-même une partie formant couvercle 26 munie d'une jupe cylindrique 27 qui vient s'appliquer contre la partie intérieure 30, légèrement conique, du roulé 23. Le serrage étanche est réalisé par rotation des organes de blocage 28, les excentriques 29 formant came, étant engagés à force contre la surface inférieure du rebord annulaire 19.  This mixer itself comprises a part forming a cover 26 provided with a cylindrical skirt 27 which is applied against the interior part 30, slightly conical, of the roll 23. The tight tightening is carried out by rotation of the locking members 28, the eccentrics 29 forming a cam, being forcibly engaged against the lower surface of the annular flange 19.
