Abstract

The lid has a supple peripheral seal (11) which is applied to the outer rim (13, 13') of the paint tin (5) when the agitator lid is closed. The seal comprises an annular member (17) which is fixed to the base of the lid and pressed against the paint tin rim, and an inner supple seal lip (19) which is fixed to the annular member (17) and applied to the inner rim (15, 15') of the paint tin opening when the lid is closed. The supple lip is made in one piece with the outer member of the seal, e.g. by moulding from a supple synthetic material which is resistant to paint solvents. It has a regular cross-section which tapers inwards, and slopes downwards from the outer member at an angle slightly greater than the maximum slope between the inner and outer rims, e.g. 30 degrees. The radial length of the supple lip (19) is slightly greater than the maximum radial length between the outer and inner rims, e.g. some 15 mm; it can also have an inner elastic reinforcing element.

Description

La présente invention concerne les couvercles agitateurs pour boîtes de teintes équipant les machines d'agitation de peinture, et en particulier, un couvercle agitateur du type comportant à sa base un joint souple périphérique de fermeture, destiné à être appliqué serré, avec étanchéité, sur le bord supérieur correspondant d'ouverture des boîtes de teintes, qui puisse s'adapter aux diverses boîtes de teintes existantes et avec perfectionnement de la fermeture sur leur rebord.The present invention relates to agitator covers for color boxes fitted to paint stirring machines, and in particular, an agitator cover of the type comprising at its base a flexible peripheral sealing joint, intended to be applied tightly, with sealing, on the corresponding upper edge for opening the color boxes, which can be adapted to the various existing color boxes and with perfecting the closure on their rim.

On sait que les boîtes de teintes sont pourvues d'un rebord périphérique supérieur d'ouverture coopérant en fermeture avec le couvercle de fermeture de la boîte et dont le profil de section du rebord est variable, de la forme en U classique à la forme en V retourné.It is known that the color boxes are provided with an upper peripheral opening rim cooperating in closing with the closing lid of the box and whose section profile of the rim is variable, from the conventional U shape to the V returned.

Les couvercles agitateurs connus, du type à joint souple de fermeture sur la boîte sous-jacente ne permettent que l'application en fermeture, sur le listel de bord supérieur périphérique de sertissage du rebord d'ouverture de la boîte.The known agitator covers, of the type with flexible closing seal on the underlying box, only allow the application in closing, on the top peripheral edge crimping strip of the opening rim of the box.

Cependant, cette application sur le listel de bord de sertissage du rebord d'ouverture de boîte, ne peut empêcher que de la peinture ne s'introduise à l'intérieur de la cavité du rebord, par exemple lors de l'inclinaison de la boîte lors de la manoeuvre de versement de la peinture par le couvercle, et ne vienne polluer par formation d'amalgames en séchant la peinture contenue dans la boîte.However, this application on the crimping edge list of the can opening rim cannot prevent paint from getting inside the rim cavity, for example when tilting the can. during the paint pouring operation by the cover, and does not come to pollute by the formation of amalgams by drying the paint contained in the box.

L'invention vise à remédier à cet inconvénient et propose un couvercle agitateur pour boîtes de teintes sur les machines d'agitation, du type comportant à sa base un joint souple périphérique, destiné à être appliqué, à la fermeture du couvercle agitateur sur la boîte, sur le bord périphérique externe du rebord annulaire délimitant l'ouverture de la boîte, caractérisé en ce que ledit joint comporte une partie du corps antérieure annulaire fixée à ladite base du couvercle et destinée à être appliquée à la fermeture en pression et de façon étanche sur ledit bord périphérique de la boîte, et une lèvre annulaire interne souple solidaire de ladite partie de corps antérieure, coaxiale à la partie de corps, et destinée à être appliquée à la fermeture sur le bord interne du rebord annulaire d'ouverture de la boîte.The invention aims to remedy this drawback and proposes an agitator cover for boxes of colors on stirring machines, of the type comprising at its base a peripheral flexible seal, intended to be applied, when the agitator cover is closed on the box. , on the outer peripheral edge of the annular rim defining the opening of the box, characterized in that said seal comprises a part of the annular anterior body fixed to said base of the cover and intended to be applied to the pressure and sealing closure on said peripheral edge of the box, and a flexible internal annular lip integral with said anterior body part, coaxial with the body part, and intended to be applied to closure on the internal edge of the rim box opening ring.

Grâce à cette disposition, la lèvre souple vient s'appliquer, à la fermeture du couvercle sur la boîte, sur le bord interne du rebord d'ouverture de la boîte en épousant son profil et constitue ainsi une seconde zone d'étanchéité de fermeture, complémentairement à la première zone d'étanchéité constituée par l'application de ladite partie de corps sur le bord périphérique de la boîte, ce qui évite ainsi que la peinture soit amenée à l'intérieur de la cavité du rebord lors de la manoeuvre du couvercle agitateur avec la boîte de teintes.Thanks to this arrangement, the flexible lip is applied, when the cover is closed on the box, on the internal edge of the opening rim of the box by matching its profile and thus constitutes a second closing sealing zone, in addition to the first sealing zone formed by the application of said body part to the peripheral edge of the box, which thus prevents the paint from being brought inside the rim cavity during the operation of the cover shaker with box of shades.

Selon des caractéristiques avantageuses de l'invention, la lèvre souple est formée de façon monobloc avec ladite partie antérieure de corps du joint, issue par exemple de moulage avec cette dernière en matière synthétique souple résistant aux solvants des peintures.According to advantageous characteristics of the invention, the flexible lip is formed in a single piece with said front part of the body of the seal, obtained for example from molding with the latter of flexible synthetic material resistant to paint solvents.

Cette lèvre souple a un profil de section régulier effilé vers l'intérieur et est dirigée vers le bas en position naturelle selon un angle de pente déterminé relativement au plan du joint, légèrement supérieur à la ligne de pente maximale entre les bords périphérique et interne du rebord des boîtes de teintes existantes. Cet angle peut être d'environ trente degrés.This flexible lip has a regular section profile tapered inwards and is directed downwards in the natural position at a determined angle of slope relative to the plane of the joint, slightly greater than the maximum line of slope between the peripheral and internal edges of the edge of existing color boxes. This angle can be about thirty degrees.

Elle est en outre mobile angulairement avec rappel élastique à la position naturelle, s'adaptant ainsi aux divers profils de rebords de boîte pour venir au maximum sensiblement à l'horizontale, en étant toujours appliquée sur le bord interne du rebord d'ouverture de boîte. De plus, cette lèvre a une longueur radiale légèrement supérieure à la plus grande longueur radiale existante entre le bord supérieur externe et le bord interne du rebord d'ouverture des boîtes, et par exemple d'environ 15 mm. Grâce à cette disposition, le couvercle selon l'invention peut s'adapter en fermeture à l'ensemble des boîtes de peinture existant sur le marché.It is also angularly movable with elastic return to the natural position, thus adapting to the various profiles of box edges to come as close as possible to the horizontal, while always being applied to the internal edge of the box opening edge. . In addition, this lip has a radial length slightly greater than the greatest radial length existing between the external upper edge and the internal edge of the opening flange of the boxes, and for example of approximately 15 mm. Thanks to that arrangement, the cover according to the invention can be adapted in closure to all the paint cans existing on the market.

La partie de corps antérieure du joint est de préférence fixée avec engagement élastique, par encliquetage dans un logement complémentaire formé à la base du couvercle.The front body part of the seal is preferably fixed with elastic engagement, by snapping into a complementary housing formed at the base of the cover.

Cette dernière comporte une jupe verticale externe périphérique formant saillie vers le bas relativement au joint pour le centrage de fermeture du couvercle sur la boîte. Cette disposition facilite le montage rapide du joint et la manoeuvre de montage du couvercle sur la boîte de teintes.The latter comprises a peripheral external vertical skirt projecting downward relative to the seal for closing the closure of the lid on the box. This arrangement facilitates the rapid assembly of the seal and the assembly operation of the cover on the shade box.

L'invention est illustrée ci-après à l'aide d'un exemple de réalisation et en référence au dessin annexé, sur lequel :

  • La figure unique est une vue en coupe partielle d'un couvercle selon l'invention appliqué en fermeture sur une boîte de teintes, représenté uniquement au niveau de sa base ou bord sur le rebord de la boîte en raison de la symétrie circulaire, respectivement sur deux rebords d'ouverture en trait plein et en trait mixte, délimitant les deux formes extrêmes de rebord d'ouverture des boîtes de teintes.
The invention is illustrated below with the aid of an exemplary embodiment and with reference to the appended drawing, in which:
  • The single figure is a partial sectional view of a cover according to the invention applied as a closure to a box of colors, represented only at its base or edge on the edge of the box due to the circular symmetry, respectively on two opening edges in solid line and in broken line, delimiting the two extreme forms of opening edge of the color boxes.

La figure montre une coupe radiale partielle du couvercle 1 selon l'invention, prise au niveau de son bord de fermeture 3, appliqué respectivement sur une boîte de peinture 5 comportant un rebord d'ouverture 7 à forme de U en trait plein et à forme de V renversé 7' en trait mixte. L'ensemble comporte une symétrie de rotation par rapport à l'axe médian du couvercle (ou de la boîte). Le couvercle agitateur est classique comportant un corps 9 à forme générale de calotte ouverte vers le bas, pourvu d'un bec verseur incorporé et d'un fourreau de passage axial d'un axe agitateur (non représentés). Il comporte à faible distance de son bord périphérique circulaire 3 et sur sa base un joint d'étanchéité annulaire 11 par lequel il peut être monté fermé avec étanchéité sur l'ouverture de la boîte de peinture sous jacente 5. Cette dernière comporte à son ouverture comme précité un rebord annulaire interne 7 de forme variable selon les constructeurs, qui peut être à forme de U classique (en trait plein) ou se développer en forme de V retourné (en trait mixte). Ce rebord métallique est solidarisé à la paroi de la boîte 5 par un bord de sertissage périphérique supérieur annulaire 13 et comporte en outre un bord extrême interne 15 arrondi vers le haut et dont l'arête du pli est tournée vers le bas dans la direction verticale.The figure shows a partial radial section of the cover 1 according to the invention, taken at its closing edge 3, applied respectively to a paint can 5 comprising an opening flange 7 in the shape of U in solid line and in shape of inverted V 7 'in phantom. The assembly has rotational symmetry with respect to the median axis of the cover (or of the box). The agitator cover is conventional comprising a body 9 in the general shape of a cap open towards the bottom, provided with an incorporated pouring spout and a sheath for axial passage of an agitator axis (not shown). It has a short distance from its circular peripheral edge 3 and on its base an annular seal 11 by which it can be mounted closed with sealing on the opening of the underlying paint box 5. The latter has at its opening as mentioned above an internal annular rim 7 of variable shape according to the manufacturers, which can be in the shape of a classic U (in solid line) or develop in the shape of an inverted V (in dashed line). This metal rim is secured to the wall of the box 5 by an annular upper peripheral crimping edge 13 and further comprises an inner end edge 15 rounded upward and whose fold edge is turned downward in the vertical direction. .

Le joint est en matière synthétique élastomère résistant aux solvants du type thermoplastique injecté sous pression. Les composites de polysulfones conviennent à cet effet. Il comporte en section une partie de corps antérieure épaisse 17 et une lèvre arrière effilée 19 et dirigée vers le bas, l'ensemble étant formé de façon annulaire avec symétrie par rapport à l'axe médian. La partie de corps antérieure 17 a une section de forme générale carrée et la lèvre 19 est triangulaire avec une partie en pointe externe 21. Cette lèvre est solidaire de la partie de corps 17 par sa face arrière 23 avec léger décrochement de surface au niveau inférieur et un épaulement 25 au niveau supérieur. Le joint est fixé à la base du couvercle par sa partie de corps qui est engagée élastiquement en encliquetage dans un logement complémentaire 27 formé dans celle-ci. Le joint 11 introduit en poussée dans son logement 27 se met en prise automatiquement par l'effet des dents de retenue intérieures 29 formées sur la paroi interne de la jupe verticale périphérique 31 de bordure du couvercle et par l'appui, à l'opposé des dents de retenue, d'une nervure annulaire 33 formée à l'intérieur du couvercle et en butée contre l'épaulement 25. Les dents 29 sont de forme triangulaire à pointe dirigée vers le haut et l'intérieur, permettant l'enfichage de la partie de corps 17, laquelle par une rainure annulaire 35 de section complémentaire des dents reçoit ces dernières et est alors maintenue en prise. On notera, par ailleurs, que le moulage du couvercle en matière plastique oblige à prévoir des pièces éjecteurs supérieures pour le dégagement du moule de confection des couvercle à cause des dents internes (pour le démoulage), ces pièces, une fois enlevées, découvrant une partie vide 37 fermée par la partie de corps 17 du joint.The seal is made of elastomeric synthetic material resistant to solvents of the thermoplastic type injected under pressure. Polysulfone composites are suitable for this purpose. It has in section a thick front body part 17 and a tapered rear lip 19 and directed downwards, the assembly being formed annularly with symmetry with respect to the median axis. The front body part 17 has a generally square section and the lip 19 is triangular with an external pointed part 21. This lip is integral with the body part 17 by its rear face 23 with slight surface recess at the lower level. and a shoulder 25 at the upper level. The seal is fixed to the base of the cover by its body part which is engaged resiliently by snap-fastening in a complementary housing 27 formed therein. The gasket 11 pushed into its housing 27 automatically engages by the effect of the internal retaining teeth 29 formed on the internal wall of the peripheral vertical skirt 31 of the edge of the cover and by the support, opposite retaining teeth, an annular rib 33 formed inside the cover and in abutment against the shoulder 25. The teeth 29 are of triangular shape with point directed upwards and inside, allowing the insertion of the body part 17, which by an annular groove 35 of complementary section of the teeth receives the latter and is then held in engagement. Note, moreover, that the molding of the plastic cover requires the provision of upper ejector parts for the release of the cover-making mold because of the internal teeth (for demolding), these parts, once removed, revealing an empty part 37 closed by the body part 17 of the joint.

Ces dents 29 de faible largeur, 3 à 4 mm, sont disposées régulièrement sur la périphérie du couvercle, par exemple selon un angle d'environ 30-40°, et viennent en prise sensiblement au milieu de la face antérieure 39 de la partie de corps 17.These teeth 29 of small width, 3 to 4 mm, are regularly arranged on the periphery of the cover, for example at an angle of about 30-40 °, and come into engagement substantially in the middle of the front face 39 of the part of body 17.

Il n'est pas nécessaire que la face inférieure 41 de la partie de corps ait une largeur importante car la position du bord 13 de sertissage du rebord d'ouverture des boîtes existant sur le marché varie peu en dimension. Ceci apparaît sur le dessin où les bords, respectivement en trait plein 13 et en trait mixte 13', représentant les limites extrêmes de dimensionnement de ces bords, sont peu espacés l'un de l'autre. Le positionnement de cette partie de corps 17 sera avantageusement prévu sur la base du couvercle de façon à ce que le bord de sertissage 13 vienne porter à la fermeture du couvercle sur la boîte, sensiblement dans la partie médiane de la face inférieure 41 de cette partie de corps, et donc dans un positionnement éloigné des coins.It is not necessary for the lower face 41 of the body part to have a large width since the position of the crimping edge 13 of the opening rim of the boxes existing on the market varies little in size. This appears in the drawing where the edges, respectively in solid line 13 and in broken line 13 ', representing the extreme limits of dimensioning of these edges, are spaced apart from one another. The positioning of this body part 17 will advantageously be provided on the base of the cover so that the crimping edge 13 comes to bear when the cover is closed on the box, substantially in the middle part of the lower face 41 of this part body, and therefore in a position far from the corners.

La jupe verticale périphérique 31 du couvercle faisant saillie vers le bas de la partie de corps 17 favorise le centrage d'application du joint, à la fois sur la partie de corps 17 et sur la lèvre 19 qui porte en pression vers le bas, à la fermeture, sur le bord interne 15 du rebord.The peripheral vertical skirt 31 of the cover projecting downwards from the body part 17 promotes the centering application of the seal, both on the body part 17 and on the lip 19 which presses downwards, the closure, on the internal edge 15 of the rim.

La longueur en section radiale de cette lèvre est relativement importante, par exemple de 1,5 cm pour s'adapter à tous les profils de rebord d'ouverture de boîtes existantes. En particulier le profil 7 en U, en trait plein représenté, comporte la plus grande distance entre les bords 13, 15 du rebord.The length in radial section of this lip is relatively large, for example 1.5 cm to adapt to all the opening edge profiles of existing boxes. In particular, the U-shaped profile 7, in solid lines shown, has the greatest distance between the edges 13, 15 of the rim.

La lèvre 19 peut comporter une âme métallique élastique interne (non représentée) favorisant le rappel en pression sur le bord interne 15 et donc l'étanchéité de la fermeture à ce niveau.The lip 19 may include an internal elastic metallic core (not shown) favoring the return to pressure on the internal edge 15 and therefore the sealing of the closure at this level.

Cette lèvre est naturellement mobile par élasticité angulairement sur la partie de corps 17 pour s'adapter en hauteur au bord interne du rebord. La hauteur maximale est illustrée par le rebord 7' à forme de V renversé en trait mixte où la lèvre vient sensiblement en position horizontale sur le bord interne 15'. Dans sa position naturelle, la lèvre est dirigée vers l'intérieur et vers le bas selon un angle d'environ 30° relativement au plan du joint.This lip is naturally movable by angular elasticity on the body part 17 to adapt in height to the internal edge of the rim. The maximum height is illustrated by the rim 7 ′ in the form of an inverted V in phantom where the lip comes substantially in a horizontal position on the internal edge 15 ′. In its natural position, the lip is directed inward and downward at an angle of approximately 30 ° relative to the plane of the joint.

La fermeture du couvercle est obtenue de façon classique par application serrée du couvercle sur le rebord d'ouverture de la boîte de teintes sous-jacente, au moyen de cames rotatives 43 régulièrement disposées sur la périphérie du couvercle et portant sous le rebord 7 de la boîte.The closure of the cover is obtained in a conventional manner by tight application of the cover to the opening rim of the underlying shade box, by means of rotary cams 43 regularly arranged on the periphery of the cover and bearing under the rim 7 of the box.
