Thus, a large contact surface 18 exists between this cover 6 and the rolled O-ring part 12, so as to create a good seal and / or closure of the box 1.
  • the cover 6 has along its peripheral edge 14 a flange 19 directed towards the internal surface 11 of the body 4, this flange 19 overhanging the rolled O-ring part 12, when the cover 6, in the service position, closes the box 1.
  • the cover 6 advantageously has, in the vicinity of its peripheral edge 14, a circular groove 20 open towards the outside of the box 1, when this cover 6 closes the latter.
  • This circular groove 20 is flared towards the outside of the box 1 and extends up to a level 21 lower than that 22 of the annular cavity 15.
  • This groove 20 has, starting from the peripheral edge 14 towards the axis 16, a wall 23 inclined with respect to the axis 16 and directed towards the interior of the box 1, this wall 23 extending up to a level 24 next to the level of the center 25 of the rolled part 12, a wall 26 parallel to the axis 16 which ends in a part 27 substantially semicircular, the bottom 28 of which is situated at a level 21 below the level 22 of the cavity 15, and finally a wall 29 inclined with respect to the axis 16 and directed downwards towards the outside of the box 1.
  • the cover 6 also advantageously has a circular groove 30 open towards the inside of the box 1, this groove 30 being adjacent to the above-mentioned groove 20 and being closer to the axis 16 than this groove 20 is.

  • the bowl 34 serves as a housing for a circular plate 52 having a visible surface having the appearance and / or the coloring of the coating obtained, when the product contained in the box is applied to a surface.
  • This bowl 34 is provided with means for retaining the wafer 52 therein. These means can be located from place to place in the vicinity of the edge 56 of the bowl 34, but extend, preferably all along this edge 56. These means are, for example, constituted by a lug or an annular rim 53 protruding into the bowl 34.
  • This projection 53 has a wall 54 near the edge 56 of the bowl 34, which has the shape of an inverted truncated cone and a wall 55 near the bottom 11 of the bowl 34, which is parallel to this bottom 35.
  • the plate 52 which can be introduced and fixed in the bowl 34 by simple pressure, can be metallic and colored on one or on its two faces or in plastic colored in the mass or on its two faces.
  • the paint manufacturer can reduce its stock of covers and plates, since a plate can have the appearance of two different coatings and the covers used no longer depend on the product contained in the box.
  • the plates are colored in the mass, they can be stored without risk of deterioration due to humidity, oxygen from the ambient air, etc.
  • These plates can be obtained by example, by extrusion of a sausage which is then cut into slices.
  • the inserts can be stored in the form of a cutting rod.
  • the groove 20 and the groove 30, adjacent to each other, provide a certain elasticity at the edge of the cover 6, so as to allow easy closing of the box, that is to say an easy introduction of the rolled part 12 secured to the body 4 of the box 1 in the circular cavity 15 of the cover 6.
  • This elasticity also allows, when the cover 6 closes the box 1, the application of radial contact forces between the cover 6 and the rolled part 12 and thus improves the tightness of the closure of the box 1.
  • These radial contact forces are further increased, when the box 1 is turned upside down due to the pressure exerted on the wall 31. The box 1 can thus be turned over according to the invention safely.
  • the contact force between the cover 6 of the box according to the invention and the rolled part 12 secured to the body 4 of the box 1 also has an axial component by pinching the ends of the cavity 15 on the rolled part 12, this further improves the tightness of the closure of the box 1 according to the invention.
  • the cover 6 has a frustoconical skirt 37, the small base of which is directed towards the inside of the box 1, this skirt 37 extending from the end of the cavity 15 furthest from the edge of the cover 6 and being parallel to the wall 23 of the groove 20.

  • the covers 6 can be fitted one above the other, since the skirt 37 and the circular groove 20 have dimensions allowing the introduction (in broken lines in FIG. 2) of the skirt 37 of a cover in the circular groove of another cover. This allows easy storage of the covers 6 of the boxes 1 according to the invention (see FIG. 2).
  • the cover is prevented from detaching from the body of the box, by introducing into the groove 20 a locking ring 58, having a lug or an annular flange projecting into an annular recess in the wall 26 of the groove 20 of the cover 6.
  • This locking ring 58 cooperates with the ribs 57.
  • the locking ring 58 has a notch 59 in the shape of an inverted V intended to allow the insertion of a screwdriver.
  • the locking ring also serves as a sealing ring which ensures that the contents of the box are intact and inviolate.

La présente invention est relative à une boîte com­prenant un corps de boîte fermé à une extrémité inférieure et muni à son extrémité supérieure d'un couvercle circulaire amovible présentant une cuvette destinée à servir de logement à une plaquette et entourée d'une rainure circulaire ouverte vers l'exté­rieur de la boîte, garnie sous son bord périphérique, d'une cavité annulaire à fond arrondi, dirigée vers son axe et destinée à servir de logement à une saillie annulaire ménagée à l'intérieur du corps de la boîte.The present invention relates to a box comprising a box body closed at a lower end and provided at its upper end with a removable circular cover having a bowl intended to serve as a housing for a wafer and surrounded by a circular groove open towards the outside of the box, furnished under its peripheral edge, with an annular cavity with a rounded bottom, directed towards its axis and intended to serve as a housing for an annular projection formed inside the body of the box.

La boîte suivant l'invention est, en particulier, une boîte destinée à contenir une peinture, un vernis, un crépi, un pigment ou un autre produit de revêtement ou entrant dans la composition d'un mélange protecteur sous forme de liquide, de pâte ou de solide finement divisé.The box according to the invention is, in particular, a box intended to contain a paint, a varnish, a plaster, a pigment or another coating product or entering into the composition of a protective mixture in the form of liquid, paste or finely divided solid.

Une législation européenne a été établie récemment au sujet du transport de produits de peinture et de solvants dans des récipients métalliques ou non qui doivent pouvoir résister à des critères sévères de choc et de chute.European legislation has recently been established on the transport of paint products and solvents in metallic or non-metallic containers which must be able to withstand severe criteria of shock and fall.

On connaît par le document EP-A-0186979, un réci­pient en matière plastique muni d'une fermeture à couvercle également en matière plastique. La boîte est munie d'une bride annulaire comportant une lèvre annulaire définissant une entrée du corps de la boîte ainsi qu'un canal d'égouttement autour de cette entrée. La bride annulaire est réalisée de préférence en polypropylène et fait partie intégrante du corps de boîte.Document EP-A-0186979 discloses a plastic container provided with a lid closure, also made of plastic. The box is provided with an annular flange comprising an annular lip defining an inlet of the body of the box as well as a drip channel around this entrance. The annular flange is preferably made of polypropylene and is an integral part of the box body.

Dans ce récipient, l'étanchéité entre le couvercle et le récipient est principalement assurée par une surface de contact limitée à une bande restreinte dans laquelle les efforts de serrage sont essentiellement radiaux.In this container, the seal between the lid and the container is mainly ensured by a contact surface limited to a restricted strip in which the clamping forces are essentially radial.

Un second inconvénient de cette fermeture à couvercle réside dans le fait qu'elle ne peut pas etre mise en oeuvre dans une boîte métallique.A second drawback of this lid closure is that it cannot be used in a metal box.

On connaît aussi par le document EP-0079472, un couvercle en matière plastique, pour une boîte de peinture ou analogue. Ce couvercle présente une partie ou pièce formant une cuvette cylindrique destinée à servir de logement pour une plaquette circulaire pré­sentant une surface visible ayant la coloration et l'aspect de la peinture contenue dans la boîte, des moyens étant prévus pour retenir la plaquette dans la cuvette.Document EP-0079472 also discloses a plastic cover for a paint can or the like. This cover has a part or part forming a cylindrical bowl intended to serve as a housing for a circular plate having a visible surface having the color and the appearance of the paint contained in the box, means being provided for retaining the plate in the bowl. .

La présente invention vise à réaliser une boîte qui répond aux recommandations de la Commission Européenne en matière de transport de produits de peinture et solvants, en particulier en ce qui concerne la résis­tance au choc.The present invention aims to produce a box which meets the recommendations of the European Commission in the transport of paint products and solvents, in particular with regard to impact resistance.

La présente invention concerne une boîte comprenant un corps de boîte fermé à une extrémité inférieure et muni à son extrémité supérieure d'un couvercle circu­laire amovible présentant une cuvette destinée à ser­ vir de logement à une plaquette et entourée d'une rainure circulaire ouverte vers l'extérieur de la boîte, garnie sous son bord périphérique, d'une cavité annulaire à fond arrondi, dirigée vers son axe et destinée à servir de logement à une saillie annulaire ménagée à l'intérieur du corps de la boîte, caractéri­sé en ce que l'extrémité supérieure du corps de la boîte est coiffée d'une pièce annulaire qui en est solidaire et qui présente, vers l'intérieur du corps de la boîte, une partie qui s'écarte de la surface interne dudit corps et présente une extrémité intéri­eure roulée de forme sensiblement torique.The present invention relates to a box comprising a box body closed at a lower end and provided at its upper end with a removable circular cover having a bowl intended to be used housing vir to a plate and surrounded by a circular groove open towards the outside of the box, furnished under its peripheral edge, with an annular cavity with rounded bottom, directed towards its axis and intended to serve as housing for a projection annular formed inside the body of the box, characterized in that the upper end of the body of the box is capped with an annular piece which is integral therewith and which, towards the inside of the body of the box, a part which deviates from the internal surface of said body and has a rolled internal end of substantially toroidal shape.

L'emploi d'une pièce annulaire présentant comme épaulement en contact avec le couvercle, un rebord to­rique roulé qui épouse le couvercle sur un arc de contact de plus de 120° améliore l'étanchéité de la boîte et améliore l'ancrage du couvercle sur la boîte et permet donc d'éviter tout risque d'enlèvement acci­dentel de ce couvercle.The use of an annular piece having as a shoulder in contact with the cover, a rolled O-ring flange which marries the cover on a contact arc of more than 120 ° improves the sealing of the box and improves the anchoring of the cover on the box and therefore avoids any risk of accidental removal of this cover.

La plaquette peut être une plaquette de métal d'épaisseur suffisante pour assurer une rigidité. Cha­cune de ses surfaces peut être revêtue, par exemple, par pistolage, d'une couche de peinture, ces couches pouvant être de natures ou de couleurs différentes.The plate can be a metal plate of sufficient thickness to ensure rigidity. Each of its surfaces can be coated, for example, by spraying, with a layer of paint, these layers being able to be of different natures or colors.

La plaquette peut aussi être en matière plastique, de préférence transparente. Dans ce dernier cas, la matière plastique transparente peut être colorée dans la masse à l'aide du ou des pigments contenus dans la peinture renfermée dans une boîte.The plate can also be made of plastic, preferably transparent. In the latter case, the transparent plastic material can be colored in the mass using the pigment or pigments contained in the paint enclosed in a box.

La plaquette peut se présenter sous forme d'une rondelle ou pastille rigide, de forme polygonale ou, de préférence circulaire.The plate can be in the form of a rigid washer or pad, polygonal or, preferably circular.

La plaquette peut être revêtue sur ses deux faces de couches de revêtement ayant des couleurs et/ou des aspects différents, de sorte qu'une même plaquette peut être associée à des boîtes ayant des contenus différents. Ainsi une face d'une plaquette peut être revêtue d'une couche brillante, tandis que sa face opposée peut être revêtue d'une couche mate ou satinée de la même couleur que la couche brillante. De même, une face de la plaquette peut être revêtue d'une couche ayant une couleur différente de celle appliquée sur son autre face.The plate can be coated on both sides with coating layers having different colors and / or aspects, so that the same plate can be combined with boxes having different contents. Thus one side of a wafer can be coated with a glossy layer, while its opposite side can be coated with a matt or satin layer of the same color as the glossy layer. Likewise, one face of the wafer can be coated with a layer having a color different from that applied to its other face.

Ainsi, le nombre de plaquettes et de couvercles dont doit disposer le fabricant de peintures ou de produits analogues est sensiblement réduit.Thus, the number of plates and covers which the manufacturer of paints or similar products must have is significantly reduced.

L'invention concerne également un procédé pour sceller une boîte à couvercle telle que décrite ci-­dessus, suivant lequel on empêche le couvercle de se détacher du corps de la boîte, en introduisant dans la rainure un anneau de blocage, présentant un ergot ou un rebord annulaire faisant saillie dans un évidement annulaire de la paroi de la rainure du couvercle.The invention also relates to a method for sealing a cover box as described above, according to which the cover is prevented from detaching from the body of the box, by introducing into the groove a locking ring, having a lug or a annular rim projecting into an annular recess in the wall of the cover groove.

Elle concerne aussi une boîte munie d'un couvercle maintenu en place par un anneau de blocage et de scel­lement.It also relates to a box provided with a cover held in place by a locking and sealing ring.

D'autres particularités et détails de l'invention ressortiront de la description suivante dans laquelle il est fait référence aux dessins ci-annexés et dans lesquels :

  • - la figure 1 est une coupe transversale d'une boîte suivant l'invention;
  • - la figure 2 est à plus grande échelle, une coupe transversale d'une partie du couvercle de la boîte et de l'extrémité de celle-ci, dans laquelle s'em­boîte le couvercles;
  • - la figure 3 est une vue semblable à celle de la fi­gure 2 montrant le couvercle emboîté dans la boîte, et
  • - les figures 4, 5 et 6 sont des vues en plan et en perspective d'un anneau de blocage et d'invio­labilité du couvercle sur la boîte.
Other particularities and details of the invention will emerge from the following description in which reference is made to the attached drawings and in which:
  • - Figure 1 is a cross section of a box according to the invention;
  • - Figure 2 is on a larger scale, a cross section of a portion of the cover of the box and the end thereof, in which fits the covers;
  • FIG. 3 is a view similar to that of FIG. 2 showing the cover fitted into the box, and
  • - Figures 4, 5 and 6 are plan and perspective views of a locking and tamper-evident ring of the cover on the box.

Dans ces différentes figures, les mêmes signes de référence désignent des éléments identiques.In these different figures, the same reference signs designate identical elements.

Ces figures représentent une boîte 1, de préférence cylindrique, fermée à une extrémité 2 par un fond 3 serti de façon connue au corps 4 de la boîte 1.These figures represent a box 1, preferably cylindrical, closed at one end 2 by a bottom 3 crimped in a known manner to the body 4 of the box 1.

Ce corps cylindrique 4 est muni à son autre extré­mité 5 d'une pièce annulaire 7 apte à recevoir un cou­vercle circulaire amovible 6. Cette pièce annulaire 7 comporte une partie extérieure 8 qui est sertie sur la surface externe 9 du corps 4 et une partie intérieure qui s'écarte de la surface interne 11 du corps 4 et qui présente une extrémité intérieure 12 roulée vers l'intérieur et vers le haut de forme sensiblement to­rique. Entre sa partie extérieure 8 et son extrémité roulée 12, la pièce annulaire 7 présente une jupe 13 qui est parallèle à la surface interne 11 du corps 4 au voisinage de sa partie extérieure 8, et est perpen­diculaire à cette surface interne 11 du corps 4 au voisinage de l'extrémité roulée 12.This cylindrical body 4 is provided at its other end 5 with an annular part 7 capable of receiving a removable circular cover 6. This annular part 7 has an external part 8 which is crimped on the external surface 9 of the body 4 and an internal part which deviates from the internal surface 11 of the body 4 and which has an internal end 12 rolled inwards and upwards of substantially toroidal shape. Between its outer part 8 and its rolled end 12, the annular part 7 has a skirt 13 which is parallel to the internal surface 11 of the body 4 in the vicinity of its external part 8, and is perpendicular to this internal surface 11 of the body 4 at near the rolled end 12.

Le couvercle circulaire amovible 6 présente juste sous son bord périphérique 14 une cavité annulaire 15 à fond arrondi dirigée vers son axe 16 et destinée à servir de logement à la partie torique roulée 12 de la pièce annulaire 7.The removable circular cover 6 has just under its peripheral edge 14 an annular cavity 15 with a rounded bottom directed towards its axis 16 and intended to serve as a housing for the rolled toric part 12 of the annular part 7.

Cette cavité 15 a des dimensions telles que la par­tie torique roulée 12 de la pièce annulaire 7 épouse le fond 17 de cette cavité 15 sur plus de 120°, de préférence 135°, lorsque le couvercle 6 obture la boîte 1. Ainsi, une grande surface de contact 18 existe entre ce couvercle 6 et la partie torique rou­lée 12, de manière à créer une bonne étanchéité et/ou fermeture de la boîte 1.This cavity 15 has dimensions such that the rolled O-ring part 12 of the annular part 7 follows the bottom 17 of this cavity 15 over more than 120 °, preferably 135 °, when the cover 6 closes the box 1. Thus, a large contact surface 18 exists between this cover 6 and the rolled O-ring part 12, so as to create a good seal and / or closure of the box 1.

Le couvercle 6 présente le long de son bord péri­phérique 14 un rebord 19 dirigé vers la surface inter­ne 11 du corps 4, ce rebord 19 surplombant la partie torique roulée 12, lorsque le couvercle 6, en position de service, ferme la boîte 1.The cover 6 has along its peripheral edge 14 a flange 19 directed towards the internal surface 11 of the body 4, this flange 19 overhanging the rolled O-ring part 12, when the cover 6, in the service position, closes the box 1.

Le couvercle 6 présente avantageusement au voisina­ge de son bord périphérique 14 une rainure circulaire 20 ouverte vers l'extérieur de la boîte 1, lorsque ce couvercle 6 obture celle-ci. Cette rainure circulaire 20 est évasée vers l'extérieur de la boîte 1 et s'étend jusqu'à un niveau 21 inférieur à celui 22 de la cavité annulaire 15.The cover 6 advantageously has, in the vicinity of its peripheral edge 14, a circular groove 20 open towards the outside of the box 1, when this cover 6 closes the latter. This circular groove 20 is flared towards the outside of the box 1 and extends up to a level 21 lower than that 22 of the annular cavity 15.

Cette rainure 20 a, en partant du bord périphérique 14 vers l'axe 16, une paroi 23 inclinée par rapport à l'axe 16 et dirigée vers l'intérieur de la boîte 1, cette paroi 23 s'étendant jusqu'à un niveau 24 voisin du niveau du centre 25 de la partie roulée 12, une paroi 26 parallèle à l'axe 16 qui se termine par une partie 27 sensiblement semi-circulaire, dont le fond 28 est situé à un niveau 21 inférieur au niveau 22 de la cavité 15, et enfin une paroi 29 inclinée par rapport à l'axe 16 et dirigée vers le bas vers l'exté­rieur de la boîte 1.This groove 20 has, starting from the peripheral edge 14 towards the axis 16, a wall 23 inclined with respect to the axis 16 and directed towards the interior of the box 1, this wall 23 extending up to a level 24 next to the level of the center 25 of the rolled part 12, a wall 26 parallel to the axis 16 which ends in a part 27 substantially semicircular, the bottom 28 of which is situated at a level 21 below the level 22 of the cavity 15, and finally a wall 29 inclined with respect to the axis 16 and directed downwards towards the outside of the box 1.

Le couvercle 6 présente également de façon avanta­geuse une gorge circulaire 30 ouverte vers l'intérieur de la boîte 1, cette gorge 30 étant adjacente à la rainure précitée 20 et étant plus proche de l'axe 16 que ne l'est cette rainure 20.The cover 6 also advantageously has a circular groove 30 open towards the inside of the box 1, this groove 30 being adjacent to the above-mentioned groove 20 and being closer to the axis 16 than this groove 20 is.

Cette gorge 30 présente, en partant du côté le plus proche de l'axe 16 vers le bord périphérique 14 du couvercle, une paroi 31 sensiblement parallèle à l'axe 16 qui se termine par une partie sensiblement semi-­circulaire 32, et enfin une paroi 33 inclinée par rapport à l'axe 16 et évasée vers l'intérieur de la boîte 1.This groove 30 has, starting from the side closest to the axis 16 towards the peripheral edge 14 of the cover, a wall 31 substantially parallel to the axis 16 which ends in a substantially semi-circular part 32, and finally a wall 33 inclined with respect to the axis 16 and flared towards the inside of the box 1.

Le couvercle 6 est également muni d'une cuvette centrale 34 dont le fond 35 est situé à un niveau 36 voisin du niveau 25 du centre de la partie roulée 12, lorsque ce couvercle 6 obture la boîte 1.The cover 6 is also provided with a central bowl 34, the bottom 35 of which is situated at a level 36 close to the level 25 of the center of the rolled part 12, when this cover 6 closes the box 1.

Le couvercle circulaire 6 présente une cuvette centrale 34 ouverte vers l'extérieur de la boîte 1. Cette cuvette 34 présente un rebord périphérique muni d'une cavité annulaire 15 à fond arrondi. La cavité 15 est destinée à servir de logement à une partie torique roulée 10 d'une pièce annulaire 7 qui coiffe l'extré­mité 8 à obturer du corps 9 de la boîte 1, afin de maintenir en place le couvercle 6 lorsque celui-ci est placé sur la boîte 1.The circular cover 6 has a central bowl 34 open towards the outside of the box 1. This bowl 34 has a peripheral rim provided with an annular cavity 15 with a rounded bottom. The cavity 15 is intended to serve as a housing for a rolled O-ring part 10 of an annular part 7 which covers the end 8 to be closed off from the body 9 of the box 1, in order to hold the cover 6 in place when the latter is placed on the box 1.

La cuvette 34 sert de logement à une plaquette cir­culaire 52 présentant une surface visible ayant l'aspect et/ou la coloration du revêtement obtenu, lorsque le produit contenu dans la boîte est appliqué sur une surface.The bowl 34 serves as a housing for a circular plate 52 having a visible surface having the appearance and / or the coloring of the coating obtained, when the product contained in the box is applied to a surface.

Cette cuvette 34 est munie de moyens de retenue de la plaquette 52 dans celle-ci. Ces moyens peuvent être situés de place en place au voisinage du bord 56 de la cuvette 34, mais s'étendent, de préférence tout le long de ce bord 56. Ces moyens sont, par exemple, constitués par un ergot ou un rebord annulaire 53 faisant saillie dans la cuvette 34.This bowl 34 is provided with means for retaining the wafer 52 therein. These means can be located from place to place in the vicinity of the edge 56 of the bowl 34, but extend, preferably all along this edge 56. These means are, for example, constituted by a lug or an annular rim 53 protruding into the bowl 34.

Cette saillie 53 a une paroi 54 proche du bord 56 de la cuvette 34, qui présente la forme d'un tronc de cône renversé et une paroi 55 proche du fond 11 de la cuvette 34, qui est parallèle à ce fond 35.This projection 53 has a wall 54 near the edge 56 of the bowl 34, which has the shape of an inverted truncated cone and a wall 55 near the bottom 11 of the bowl 34, which is parallel to this bottom 35.

La plaquette 52 qui peut être introduite et fixée dans la cuvette 34 par simple pression, peut être métallique et colorée sur une ou sur ses deux faces ou en matière plastique colorée dans la masse ou sur ses deux faces. Lorsque les deux faces d'une plaquette 52 présentent deux couleurs différentes, le fabricant de peinture peut réduire son stock de couvercles et de plaquettes, puisqu'une plaquette peut présenter l'as­pect de deux revêtements différents et que les couver­cles utilisés ne dépendent plus du produit contenu dans la boîte.The plate 52 which can be introduced and fixed in the bowl 34 by simple pressure, can be metallic and colored on one or on its two faces or in plastic colored in the mass or on its two faces. When the two faces of a plate 52 have two different colors, the paint manufacturer can reduce its stock of covers and plates, since a plate can have the appearance of two different coatings and the covers used no longer depend on the product contained in the box.

Dans le cas où les plaquettes sont colorées dans la masse, elles peuvent être stockées sans risque de dé­térioration due à l'humidité, l'oxygène de l'air am­biant, etc. Ces plaquettes peuvent être obtenues, par exemple, par extrusion d'un boudin qui est ensuite dé­coupé en tranches. Dans ce cas, les plaquettes peuvent être stockées sous forme de boudin à tronçonner.If the plates are colored in the mass, they can be stored without risk of deterioration due to humidity, oxygen from the ambient air, etc. These plates can be obtained by example, by extrusion of a sausage which is then cut into slices. In this case, the inserts can be stored in the form of a cutting rod.

La rainure 20 et la gorge 30, adjacente l'une à l'autre, procurent une certaine élasticité au bord du couvercle 6, de manière à permettre une fermeture aisée de la boîte, c'est-à-dire une introduction aisée de la partie roulée 12 solidaire du corps 4 de la boîte 1 dans la cavité circulaire 15 du couvercle 6. Cette élasticité permet également, lorsque le couver­cle 6 obture la boîte 1, l'application de forces radiales de contact entre le couvercle 6 et la partie roulée 12 et améliore ainsi l'étanchéité de la ferme­ture de la boîte 1. Ces forces de contact radiales sont encore accrues, lorsque la boîte 1 est retournée grâce à la pression exercée sur la paroi 31. On peut ainsi retourner la boîte 1 suivant l'invention en toute sécurité.The groove 20 and the groove 30, adjacent to each other, provide a certain elasticity at the edge of the cover 6, so as to allow easy closing of the box, that is to say an easy introduction of the rolled part 12 secured to the body 4 of the box 1 in the circular cavity 15 of the cover 6. This elasticity also allows, when the cover 6 closes the box 1, the application of radial contact forces between the cover 6 and the rolled part 12 and thus improves the tightness of the closure of the box 1. These radial contact forces are further increased, when the box 1 is turned upside down due to the pressure exerted on the wall 31. The box 1 can thus be turned over according to the invention safely.

On rend le bord du couvercle 6 plus rigide en gar­nissant la gorge 30 de nervures radiales 57 s'appuyant à distances régulières sur les parois 31 et 32.The edge of the cover 6 is made more rigid by lining the groove 30 with radial ribs 57 bearing at regular distances on the walls 31 and 32.

Enfin, la force de contact entre le couvercle 6 de la boîte suivant l'invention et la partie roulée 12 solidaire du corps 4 de la boîte 1 possède également une composante axiale grâce au pincement des extrémi­tés de la cavité 15 sur la partie roulée 12, ceci permettant encore d'améliorer l'étanchéité de la fer­meture de la boîte 1 suivant l'invention.Finally, the contact force between the cover 6 of the box according to the invention and the rolled part 12 secured to the body 4 of the box 1 also has an axial component by pinching the ends of the cavity 15 on the rolled part 12, this further improves the tightness of the closure of the box 1 according to the invention.

Dans une forme de réalisation préférée de la boîte 1 suivant l'invention, le couvercle 6 présente une jupe tronconique 37, dont la petite base est dirigée vers l'intérieur de la boîte 1, cette jupe 37 s'éten­dant à partir de l'extrémité de la cavité 15 la plus éloignée du bord du couvercle 6 et étant parallèle à la paroi 23 de la rainure 20.In a preferred embodiment of the box 1 according to the invention, the cover 6 has a frustoconical skirt 37, the small base of which is directed towards the inside of the box 1, this skirt 37 extending from the end of the cavity 15 furthest from the edge of the cover 6 and being parallel to the wall 23 of the groove 20.

La jupe 37 constitue un chanfrein d'un pli annulai­re 38 qui présente une paroi interne tronconique 33 dont la partie évasée est dirigée vers l'intérieur de la boîte 1, cette paroi 33 étant de façon avantageuse parallèle à la paroi 29 de la rainure 20, et peut être munie sur son bord extrême 39 d'un appendice cylindri­que 40 destinée à accroître l'élasticité du couvercle 6.The skirt 37 constitutes a chamfer of an annular fold 38 which has a frustoconical internal wall 33 whose flared part is directed towards the inside of the box 1, this wall 33 being advantageously parallel to the wall 29 of the groove 20 , and can be provided on its extreme edge 39 with a cylindrical appendage 40 intended to increase the elasticity of the cover 6.

Dans cette forme de réalisation préférée, les cou­vercles 6 peuvent être emboîtés les uns au-dessus des autres, puisque la jupe 37 et la rainure circulaire 20 ont des dimensions permettant l'introduction (en traits interrompus à la figure 2) de la jupe 37 d'un couvercle dans la rainure circulaire d'un autre cou­vercle. Ceci permet un stockage facile des couvercles 6 des boîtes 1 suivant l'invention (voir figure 2).In this preferred embodiment, the covers 6 can be fitted one above the other, since the skirt 37 and the circular groove 20 have dimensions allowing the introduction (in broken lines in FIG. 2) of the skirt 37 of a cover in the circular groove of another cover. This allows easy storage of the covers 6 of the boxes 1 according to the invention (see FIG. 2).

Suivant une particularité de l'invention, on empê­che le couvercle de se détacher du corps de la boîte, en introduisant dans la rainure 20 un anneau de blocage 58, présentant un ergot ou un rebord annulaire faisant saillie dans un évidement annulaire de la paroi 26 de la rainure 20 du couvercle 6. Cet anneau de blocage 58 coopère avec les nervures 57. En s'ap­puyant sur les parois 26 et 29 de la rainure 20, on supprime la composante d'élasticité radiale du couvercle 6.According to a feature of the invention, the cover is prevented from detaching from the body of the box, by introducing into the groove 20 a locking ring 58, having a lug or an annular flange projecting into an annular recess in the wall 26 of the groove 20 of the cover 6. This locking ring 58 cooperates with the ribs 57. By pressing on the walls 26 and 29 of the groove 20, the radial elastic component of the cover 6 is removed.

Comme illustré à la figure 4, l'anneau de blocage 58 présente une entaille 59 en forme de V renversé destinée à permettre l'introduction d'un tournevis. L'anneau de blocage sert aussi d'anneau de scellement qui garantit que le contenu de la boîte est bien intact et inviolé.As illustrated in FIG. 4, the locking ring 58 has a notch 59 in the shape of an inverted V intended to allow the insertion of a screwdriver. The locking ring also serves as a sealing ring which ensures that the contents of the box are intact and inviolate.

Pour ouvrir la boîte, il suffit d'introduire un tournevis 59, maintenu vertical, dans l'entaille de l'anneau 58 de scellement et d'inviolabilité, de manière à détacher l'anneau 58 à l'endroit de l'entaille (figure 5). Ensuite, on incline le tourne­vis et on soulève une languette d'extrémité de l'anneau 58 brisé. On retire la languette de l'anneau 58 sur toute la longueur de la rainure 20 et on enlève le couvercle en le soulevant, éventuellement en intro­duisant un tournevis entre le bord périphérique 14 du couvercle et la pièce annulaire 7 (figure 6).To open the box, simply insert a screwdriver 59, kept vertical, in the notch of the sealing and tamper-evident ring 58, so as to detach the ring 58 at the location of the notch ( figure 5). Then, tilt the screwdriver and lift an end tab of the broken ring 58. The tongue of the ring 58 is removed over the entire length of the groove 20 and the cover is removed by lifting it, possibly by inserting a screwdriver between the peripheral edge 14 of the cover and the annular part 7 (FIG. 6).

Il est évident que la présente invention n'est pas limitée à l'exemple décrit ci-dessus et que bien des modifications peuvent y être apportées.It is obvious that the present invention is not limited to the example described above and that many modifications can be made to it.

Ainsi, les moyens de fixation de l'anneau d'invio­labilité 58 dans la rainure 20, peuvent être consti­tués par un ergot ménagé sur la paroi 26 de la rainure 20, cet ergot faisant saillie dans un évidement annulaire de l'anneau d'inviolabilité 58.Thus, the means for fixing the tamper-evident ring 58 in the groove 20 can be constituted by a lug formed on the wall 26 of the groove 20, this lug protruding into an annular recess in the tamper-evident ring 58.
