Description

La présente invention concerne un boítier de maquillage ou analogue, comprenant un corps logeant une réserve de produit, un couvercle et un organe d'étanchéité comportant une lèvre déformable s'étendant autour de la réserve de produit lorsque le boítier est fermé, le couvercle ou le corps du boítier venant appuyer sur ledit organe d'étanchéité lorsque le boítier est fermé.The present invention relates to a makeup case or analogous, comprising a body housing a reserve of product, a cover and a sealing member comprising a deformable lip extending around the reserve of product when the housing is closed, the cover or the body of the casing pressing on said sealing member when the housing is closed.

On connaít de nombreux boítiers de ce type.We know many cases of this type.

On connaít notamment par les brevets US 3 144 167 et 5 186 318 des boítiers comportant une lèvre d'étanchéité venue de formation avec une coupelle contenant la réserve de produit, cette lèvre s'écartant de la coupelle et du corps du boítier puis étant recourbée vers le corps du boítier à sa périphérie pour prendre appui sur celui-ci.We know in particular from US Patents 3,144,167 and 5,186,318 housings comprising a sealing lip formed by formation with a cup containing the reserve of product, this lip deviating of the cup and the body of the case then being bent towards the body of the housing at its periphery to bear on it.

Il existe un besoin pour accroítre encore l'herméticité des boítiers de maquillage afin d'empêcher l'évaporation des solvants contenus dans le produit, sans pour autant que les moyens utilisés pour obtenir l'étanchéité recherchée nuisent à l'esthétique ou rendent le boítier trop coûteux à fabriquer.There is a need to further increase the hermeticity of make-up boxes to prevent the evaporation of solvents contained in the product, without the means used to obtain the desired tightness affect the aesthetics or make the case too expensive to manufacture.

L'invention vise à proposer un nouveau boítier de maquillage, qui se caractérise par le fait que l'organe d'étanchéité est assujetti à une pièce de support, rapportée sur le corps du boítier ou sur le couvercle et s'étendant au moins en partie sous la lèvre d'étanchéité.The invention aims to propose a new makeup case, which is characterized by the fact that the sealing member is secured to a support piece, attached to the body of the housing or to the cover and extending at least partially under the sealing lip.

Dans un mode de réalisation particulier, cette pièce de support fait partie d'une coupelle logeant la réserve de produit.In a particular embodiment, this support piece is part of a cup housing the product reserve.

Ainsi, l'organe d'étanchéité peut être réalisé d'un seul tenant avec la coupelle, ce qui simplifie la fabrication du boítier puisque le nombre de pièces séparées à assembler est réduit.Thus, the sealing member can be made in one piece with the cup, which simplifies the manufacture of the case since the number of separate parts to be assembled is reduced.

Toujours dans une réalisation particulière, ladite pièce de support se présente sous la forme d'un rebord annulaire.Still in a particular embodiment, said piece of support is in the form of an annular rim.

De préférence, l'organe d'étanchéité est surmoulé sur ladite pièce de support ou réalisé par bi-injection avec elle.Preferably, the sealing member is molded onto said support piece or made by bi-injection with it.

De préférence encore, ladite pièce de support présente des ajours et l'organe d'étanchéité comporte une partie supérieure et une partie inférieure qui se raccordent au travers desdits ajours, ladite partie inférieure s'étendant sous ladite pièce de support et venant en appui sur le corps du boítier. Cette partie inférieure présente avantageusement une forme annulaire et s'applique de façon étanche sur le corps du boítier.More preferably, said support piece has openings and the sealing member comprises an upper part and a lower part which are connected through said openings, said lower part extending under said support piece and coming in support on the body of the case. This lower part presents advantageously an annular shape and applies tightly to the body of the case.

Dans une mise en oeuvre particulière de l'invention, l'organe d'étanchéité comporte deux lèvres annulaires d'étanchéité concentriques, aptes à s'appliquer de façon étanche sur le couvercle lorsque le boítier est fermé.In a particular implementation of the invention, the organ sealing has two annular sealing lips concentric, suitable for sealingly applied to the cover when the case is closed.

Dans une réalisation particulière, lesdites lèvres d'étanchéité présentent chacune en section une forme générale demi-circulaire dont la concavité est tournée vers ladite pièce de support.In a particular embodiment, said sealing lips each have a generally semicircular shape in section, the concavity is turned towards said support piece.

Dans une autre réalisation particulière, la pièce du support est constituée par un cache, éventuellement amovible, rapporté sur le corps du boítier. Ce cache peut servir par exemple à retenir dans le corps du boítier une coupelle contenant la réserve de produit.In another particular embodiment, the support part consists of a cover, possibly removable, attached to the body of the housing. This cover can be used for example to retain in the body of the housing a cup containing the reserve of product.

Il est particulièrement avantageux dans ce mode de réalisation que l'organe d'étanchéité, fixé au cache, s'interpose de façon étanche non seulement entre le cache et le couvercle lorsque le boítier est fermé mais également entre le cache et le corps du boítier, pour empêcher l'évaporation des solvants contenus dans le produit par le jeu qui existe entre le cache et le corps du boítier.It is particularly advantageous in this embodiment that the sealing member, fixed to the cover, interposes in a sealed manner not only between the cover and the cover when the case is closed but also between the cover and the body of the case, to prevent the evaporation of the solvents contained in the product by the clearance that exists between the cover and the body of the housing.

Dans une réalisation particulière, l'un du couvercle ou du corps de boítier comporte au moins une lumière réniforme et l'autre du couvercle ou du corps comporte un axe d'articulation engagé dans ladite lumière, l'agencement de ladite lumière et dudit axe d'articulation étant tel que lorsque le couvercle est fermé, l'axe d'articulation peut se déplacer dans ladite lumière de manière à ce que le couvercle vienne appuyer sur l'organe d'étanchéité d'une manière sensiblement uniforme.In a particular embodiment, one of the cover or body has at least one kidney-shaped lumen and the other of the cover or of the body has a hinge pin engaged in said light, the arrangement of said light and said axis of articulation being such that when the cover is closed, the axis of articulation can move in said light so that that the cover comes to press on the sealing member of a substantially uniformly.

On a représenté sur les figures 1 et 2 un boítier de maquillage 1 conforme à un premier exemple de réalisation de l'invention.There is shown in Figures 1 and 2 a makeup case 1 according to a first embodiment of the invention.

Ce boítier 1 comporte un corps 2 et un couvercle 3 articulé sur ce corps 2 au moyen d'une charnière 5 qui n'est visible que sur la figure 2.This housing 1 comprises a body 2 and a cover 3 hinged on this body 2 by means of a hinge 5 which is visible only on the figure 2.

Un fermoir 4 est prévu à l'opposé de cette charnière 5 pour maintenir le couvercle 3 en position de fermeture.A clasp 4 is provided opposite this hinge 5 for keep the cover 3 in the closed position.

Le corps 2 comporte une cavité centrale 6 logeant une coupelle 7 contenant une réserve de produit P, par exemple un produit de maquillage tel qu'un fond de teint ou un produit de soin.The body 2 has a central cavity 6 housing a cup 7 containing a reserve of product P, for example a product of makeup such as a foundation or a care product.

La coupelle 7 est fermée à sa partie inférieure par une paroi de fond 8 souple, permettant à l'utilisateur de pousser vers le haut un piston 9 pour distribuer le produit P à travers un tamis 10 solidaire de la partie supérieure de la coupelle 7.The cup 7 is closed at its lower part by a wall flexible bottom 8, allowing the user to push up a piston 9 for distributing the product P through a sieve 10 secured to the upper part of the cup 7.

Un tampon en mousse 14 est prévu dans le piston 9 pour homogénéiser la distribution du produit P. A foam pad 14 is provided in the piston 9 for homogenize the distribution of product P.

Ce dernier peut être pulvérulent ou pâteux par exemple.The latter can be powdery or pasty for example.

La coupelle 7 comporte une paroi cylindrique en matière plastique relativement rigide, par exemple du polypropylène ou du polyéthylène qui guide le coulissement du piston 9 et qui se prolonge à son extrémité supérieure et radialement vers l'extérieur par un rebord annulaire 11a, lequel est muni à sa périphérie d'un retour 12 dirigé vers le bas.The cup 7 has a cylindrical wall made of relatively rigid plastic material, for example polypropylene or polyethylene which guides the sliding of the piston 9 and which extends at its upper end and radially outwards by an annular flange 11 a , which is provided at its periphery with a return 12 directed downwards.

Le rebord 11a constitue une pièce de support au sens de l'invention et il est traversé par des perçages 13 angulairement répartis autour de l'axe de la coupelle 7, ces perçages servant à l'ancrage d'un organe d'étanchéité 15 en matériau élastomère qui va maintenant être décrit en référence aux figures 3 et 4.The flange 11a is a support part for the purposes of the invention and it is crossed by holes 13 angularly distributed around the axis of the cup 7, these holes serving to anchor a sealing member 15 made of elastomeric material which will now be described with reference to FIGS. 3 and 4.

L'organe d'étanchéité 15 comporte une base 20 qui recouvre une grande partie de la face supérieure du rebord annulaire 11a, se prolonge vers le bas par des ponts de matière 16 traversant les perçages 13, et forme deux lèvres annulaires 17, 18 d'étanchéité qui viennent prendre appui dans un léger renfoncement annulaire 19 de la face supérieure du corps 2 du boítier.The sealing member 15 comprises a base 20 which covers a large part of the upper face of the annular flange 11a, is extended downwards by 16 bridges of material passing through the bores 13, and forms two annular lips 17, 18 sealing which come to bear in a slight annular recess 19 on the upper face of the body 2 of the housing.

Deux lèvres annulaires concentriques 21, 22 forment saillie vers le haut sur la base 20, ces lèvres se situant sensiblement de part et d'autre des perçages 13.Two concentric annular lips 21, 22 project upwards on base 20, these lips being situated substantially on either side of the holes 13.

Les lèvres annulaires 21, 22 sont conformées pour venir au contact d'un bossage annulaire 24 du couvercle 3 lorsque ce dernier est en position de fermeture, comme représenté sur la figure 4.The annular lips 21, 22 are shaped to come to the contact of an annular boss 24 of the cover 3 when the latter is in the closed position, as shown in Figure 4.

Le rayon de courbure de ce bossage 24 est tel que les lèvres 21 et 22 s'écartent légèrement à son contact.The radius of curvature of this boss 24 is such that the lips 21 and 22 deviate slightly on contact.

L'organe d'étanchéité 15 permet d'obtenir une double étanchéité grâce au contact de chacune des lèvres 21,22 sur le couvercle, ce qui rend très difficile l'évaporation des solvants contenus dans le produit P.The sealing member 15 makes it possible to obtain a double seal through the contact of each of the lips 21, 22 on the cover, which makes it very difficult for the solvents contained in the product P.

En outre, du fait que les lèvres 21 et 22 fléchissent assez peu, elles ne risquent pas de perdre la mémoire de leur forme initiale si le boítier reste fermé pendant longtemps.In addition, the fact that the lips 21 and 22 flex enough little, they are not likely to lose the memory of their initial shape if the case remains closed for a long time.

Enfin, bien que réalisé dans une matière plastique relativement rigide, le rebord 11a peut fléchir légèrement lorsque le boítier est fermé. Finally, although made of a relatively rigid plastic, the flange 11 a can bend slightly when the housing is closed.

La déformation du rebord 11a empêche, le cas échéant, que les lèvres 21 et 22 soient soumises à une force de compression trop importante lorsque le couvercle 3 est fermé.The deformation of the rim 11 a prevents, if necessary, that the lips 21 and 22 are subjected to too great a compressive force when the cover 3 is closed.

Bien entendu, la forme de l'organe d'étanchéité n'est pas limitée à l'exemple de réalisation qui vient d'être décrit.Of course, the shape of the sealing member is not limited to the embodiment which has just been described.

A titre d'exemple, on a représenté sur la figure 5 une première variante de réalisation de l'organe d'étanchéité, lequel porte à présent la référence 30.By way of example, FIG. 5 shows a first alternative embodiment of the sealing member, which leads to presents reference 30.

L'organe d'étanchéité 30 représenté sur la figure 5 comporte une partie supérieure 31 qui recouvre partiellement la face supérieure du rebord de la coupelle 7, lequel est ici référencé 11b, et une partie inférieure 32 qui s'étend sous le rebord 11b et vient prendre appui par deux lèvres annulaires 33 et 34 sur le corps 2.The sealing member 30 shown in FIG. 5 comprises an upper part 31 which partially covers the upper face of the rim of the cup 7, which is here referenced 11b , and a lower part 32 which extends under the rim 11 b and is supported by two annular lips 33 and 34 on the body 2.

La partie supérieure 31 comporte deux lèvres annulaires 35, 36 dirigées vers le haut, délimitant entre elles une gorge 37 assez large.The upper part 31 has two annular lips 35, 36 directed upwards, delimiting between them a fairly wide groove 37.

Les parties supérieure 31 et inférieure 32 se raccordent par une pluralité de ponts de matière 41, 42 et 43, lesquels traversent des perçages 38, 39 et 40 réalisés dans le rebord 11b à des rayons différents et équirépartis angulairement autour de l'axe de la coupelle 7.The upper 31 and lower 32 parts are connected by a plurality of material bridges 41, 42 and 43, which pass through holes 38, 39 and 40 produced in the flange 11 b at different radii and angularly distributed around the axis of the cup 7.

Les ponts de matière 42 se raccordent à la partie supérieure 31 dans le fond de la gorge 37. Les ponts de matière 41 et 43 se situent de part et d'autre de cette gorge 37.The material bridges 42 are connected to the upper part 31 in the bottom of the groove 37. The material bridges 41 and 43 are located on either side of this gorge 37.

L'organe d'étanchéité 30 est surmoulé sur le rebord annulaire 11b.The sealing member 30 is molded onto the annular rim 11b .

La lèvre 33, radialement la plus extérieure, s'interpose de façon étanche entre le rebord 11b et le corps 2 du boítier et permet notamment d'empêcher que des salissures ne s'accumulent sous le rebord 11b.The lip 33, radially outermost, is interposed in a sealed manner between the flange 11 b and the body 2 of the housing and in particular makes it possible to prevent dirt from accumulating under the flange 11 b .

On a représenté sur les figures 6 et 7 une deuxième variante de réalisation de l'organe d'étanchéité, lequel est ici référencé 50.FIGS. 6 and 7 show a second variant of realization of the sealing member, which is here referenced 50.

Le rebord de la coupelle 7 porte la référence 11c et diffère des rebords 11a et 11b précédemment décrits par le fait qu'il est moins large.The rim of the cup 7 bears the reference 11 c and differs from the rims 11 a and 11 b previously described by the fact that it is less wide.

L'organe d'étanchéité 50 comporte une lèvre annulaire 51 qui s'étend radialement vers l'extérieur et vers le haut, en porte à faux par rapport au rebord 11c. The sealing member 50 comprises an annular lip 51 which extends radially outwards and upwards, cantilevered with respect to the flange 11 c .

Cette lèvre annulaire 51 est prolongée, vers le bas, par des points de matière 52 qui traversent des perçages 53 du rebord llc et qui se raccordent sur un bourrelet annulaire 54 venant prendre appui de façon étanche sur le corps 2 du boítier.This annular lip 51 is extended downwards by material points 52 which pass through holes 53 of the edge llc and which are connected to an annular bead 54 coming to bear tightly on the body 2 of the housing.

Lorsque le boítier est fermé, le couvercle 3 appuie sur le bord libre de la lèvre 51 qui fléchit.When the case is closed, the cover 3 presses on the edge free of lip 51 which flexes.

Le contact entre la lèvre 51 et le couvercle s'effectue selon une bande annulaire très étroite, ce qui permet d'obtenir une pression de contact élevée, favorable à une bonne étanchéité.The contact between the lip 51 and the cover takes place according to a very narrow annular band, which allows to obtain a pressure high contact, favorable to a good seal.

On a représenté sur les figures 8 et 9 un organe d'étanchéité 60 qui diffère de l'organe d'étanchéité 15, précédemment décrit en référence aux figures 2 à 4, par la forme de la partie supérieure qui recouvre partiellement le rebord de la coupelle 7, référencé ici 11d, et sensiblement identique aux rebords 11a et 11b précédemment décrits.There is shown in Figures 8 and 9 a sealing member 60 which differs from the sealing member 15, previously described with reference to Figures 2 to 4, by the shape of the upper part which partially covers the edge of the cup 7, referenced here 11 d , and substantially identical to the edges 11 a and 11 b previously described.

L'organe d'étanchéité 60 est fixé sur le rebord 11d sensiblement de la même façon que l'organe d'étanchéité 15 précédemment décrit.The sealing member 60 is fixed to the flange 11 d in substantially the same way as the sealing member 15 previously described.

La partie supérieure de l'organe d'étanchéité 60 comporte deux lèvres ou bourrelets annulaires 62 et 63 ménageant entre eux une gorge 64 assez étroite.The upper part of the sealing member 60 has two annular lips or beads 62 and 63 forming a groove therebetween 64 quite narrow.

La partie supérieure de l'organe d'étanchéité est en outre reliée, par des ponts de matière 61, à une partie inférieure constituée par des lèvres 65,66 concentriques reposantsur le corps 2 du boítier.The upper part of the sealing member is further connected, by bridges of material 61, to a lower part consisting of concentric 65,66 lips resting on the body 2 of the housing.

Le couvercle 3 comporte deux nervures annulaires concentriques 68, 69 formant saillie sous sa face intérieure et disposées de manière à s'appliquer sur le sommet des bourrelets 62 et 63 lorsque le boítier est fermé, comme représenté sur la figure 9.The cover 3 has two concentric annular ribs 68, 69 projecting under its inner face and arranged so to be applied to the top of the beads 62 and 63 when the housing is closed, as shown in figure 9.

Les bourrelets 68 et 69 s'aplatissent légèrement au contact des nervures 68 et 69, leur déformation étant facilitée par la présence de la gorge 64.The beads 68 and 69 flatten slightly in contact with the ribs 68 and 69, their deformation being facilitated by the presence of throat 64.

L'organe d'étanchéité 70, représenté sur la figure 10, comporte des plots 71 qui sont logés dans des perçages 72 du rebord 11. Ces plots 71 sont prolongés vers le haut par une lèvre souple 73 qui s'amincit et qui est dirigée radialement vers l'extérieur. The sealing member 70, shown in FIG. 10, comprises studs 71 which are housed in holes 72 of the rim 11. These studs 71 are extended upwards by a flexible lip 73 which thins and is directed radially outwards.

A la différence des réalisations précédemment décrites, l'organe d'étanchéité 70 ne se prolonge pas sous le rebord de la coupelle 7, ici référencé 11e.Unlike the embodiments previously described, the sealing member 70 does not extend under the rim of the cup 7, here referenced 11 e .

L'étanchéité entre le corps du boítier et le couvercle est obtenue, lorsque le boítier est fermé, par flexion de la lèvre 73, d'une manière analogue à ce qui a été décrit en référence aux figures 6 et 7.The seal between the body of the case and the cover is obtained, when the housing is closed, by bending the lip 73, analogously to what has been described with reference to the figures 6 and 7.

Pour empêcher aux impuretés de gagner l'espace situé sous le rebord 11c, on a réalisé sur le corps 2 du boítier une nervure annulaire 75 et à la périphérie du rebord 11e un retour 76 vers le bas, destiné à venir au contact de la face radialement la plus extérieure de la nervure 75.To prevent impurities from gaining space under the rim 11 c , an annular rib 75 has been produced on the body 2 of the housing and at the periphery of the rim 11 e a return 76 downwards, intended to come into contact with the radially outermost face of the rib 75.

On a représenté sur la figure 11 un organe d'étanchéité 80 conforme à un autre exemple de réalisation de l'invention.FIG. 11 shows a sealing member 80 according to another embodiment of the invention.

Dans cet exemple, le rebord de la coupelle, référencé 11f, est entièrement plat.In this example, the rim of the cup, referenced 11 f , is entirely flat.

La coupelle 7, à fond souple, décrite en référence à la figure 2, a été remplacée dans cet exemple, par une coupelle à fond rigide.The cup 7, with a flexible bottom, described with reference to the figure 2, has been replaced in this example, by a cup with a rigid bottom.

Dans ce cas, le prélèvement du produit par l'utilisateur s'effectue sans avoir à pousser le fond de la coupelle, et il n'est pas nécessaire de prévoir un accès par l'utilisateur au fond de la coupelle depuis l'extérieur du boítier.In this case, the removal of the product by the user without having to push the bottom of the cup, and it is not no need for user access to the bottom of the cup from outside the case.

L'organe d'étanchéité 80 comporte une partie supérieure 81 qui comprend deux lèvres 82 et 83 en appui sur le rebord 11f et ayant chacune en section une forme demi-circulaire dont la concavité est tournée vers le rebord 11f.The sealing member 80 comprises an upper part 81 which comprises two lips 82 and 83 bearing on the flange 11 f and each having in section a semi-circular shape whose concavity is turned towards the flange 11 f .

Les lèvres 82 et 83 se raccordent à une partie centrale 84 plate.The lips 82 and 83 are connected to a central part 84 flat.

Cette partie centrale 84 est prolongée vers le bas par quelques ponts de matière 86 traversant des perçages du rebord 11f.This central part 84 is extended downwards by a few bridges of material 86 crossing holes in the rim 11 f .

Ces ponts de matière 86 se raccordent chacun à leur extrémité inférieure à deux lèvres 87, 88 annulaires concentriques.These material bridges 86 are each connected at their end. lower than two lips 87, 88 concentric annulars.

Un épaulement 89 peut en outre être formé à la base des lèvres 87,88, comme représenté, pour prendre appui sur la face inférieure du rebord 11f et améliorer l'ancrage du joint d'étanchéité sur celui-ci. A shoulder 89 can also be formed at the base of the lips 87, 88, as shown, to bear on the underside of the flange 11 f and improve the anchoring of the seal thereon.

Le couvercle 3 comporte deux nervures annulaires 90, 91 destinées à venir appuyer sur le sommet des lèvres 82, 83 lorsque le boítier est fermé.The cover 3 has two annular ribs 90, 91 intended to come to press on the top of the lips 82, 83 when the case is closed.

Dans tous les exemples décrits, la coupelle contenant la réserve de produit est avantageusement remplie à part puis montée sur le corps du boítier.In all the examples described, the cup containing the product reserve is advantageously filled separately and then mounted on the body of the case.

Bien que dans les exemples décrits, l'organe d'étanchéité soit assujetti à la coupelle logeant la réserve de produit, on ne sort pas du cadre de l'invention en rendant l'organe d'étanchéité solidaire d'une toute autre pièce de support rapportée sur le couvercle ou sur le corps du boítier.Although in the examples described, the sealing member is subject to the cup housing the product reserve, we do not go out of the scope of the invention by making the sealing member integral any other support piece attached to the cover or on the body of the case.

A titre d'exemple, on a représenté sur la figure 12 un mode de réalisation dans lequel l'organe d'étanchéité est assujetti à un cache 95 en matière plastique rigide qui est rapporté sur le corps du boítier.By way of example, FIG. 12 shows a mode of embodiment in which the sealing member is subject to a cover 95 in rigid plastic which is attached to the body of the housing.

Plus particulièrement, ce cache 95 sert dans l'exemple décrit à maintenir un tamis 99 en place au-dessus du produit P.More particularly, this cover 95 is used in the example described at maintain a sieve 99 in place above the product P.

Le cache 95 comporte à sa périphérie un rebord 96 conformé pour s'encliqueter dans une gorge 97 du corps du boítier.The cover 95 has at its periphery a rim 96 shaped to snap into a groove 97 of the housing body.

Le cache 95 est en outre recourbé à son bord radialement intérieur pour venir en appui contre le tamis 99.The cover 95 is further curved at its edge radially inside to bear against the sieve 99.

L'organe d'étanchéité peut être constitué par l'un quelconque des organes d'étanchéité précédemment décrits en référence aux figures 2 à 11.The sealing member can be constituted by any one sealing members previously described with reference to the figures 2 to 11.

On a représenté à titre d'exemple sur la figure 12 un organe d'étanchéité identique à l'organe d'étanchéité 30 précédemment décrit en référence à la figure 5.An organ is shown by way of example in FIG. 12 identical to the sealing member 30 previously described with reference to Figure 5.

Cet organe d'étanchéité assure à la fois l'étanchéité entre le cache 95 et le corps 2 du boítier et l'étanchéité entre le cache 95 et le couvercle 3 lorsque le boítier est fermé.This sealing member ensures both the seal between the cover 95 and the body 2 of the housing and the seal between the cover 95 and the cover 3 when the housing is closed.

On a pu constater que grâce à l'étanchéité entre le cache et le corps du boítier on pouvait empêcher l'évaporation des solvants contenus dans le produit P par le jeu qui existe entre le cache 95 et le corps 2 du boítier.We have seen that thanks to the seal between the cover and the body of the housing could prevent evaporation of solvents contained in the product P by the play which exists between the cache 95 and the body 2 of the housing.

On a représenté sur les figures 13 à 15 une façon avantageuse de réaliser la charnière qui permet l'articulation du couvercle sur le corps du boítier. Figures 13 to 15 show advantageously to realize the hinge which allows the articulation of the cover on the body of the housing.

De préférence, on utilise un axe 100 fixé sur le corps 2 du boítier, dont les extrémités dépassent de ce corps pour servir de pivot au couvercle.Preferably, a pin 100 is used fixed on the body 2 of the housing, the ends of which protrude from this body to serve as pivot to the cover.

Plus précisément, ces extrémités sont engagées dans deux lumières 101 réniformes du couvercle 3, ces lumières 101 étant réalisées dans des flasques 104 généralement orientés perpendiculairement au plan du couvercle.Specifically, these ends are engaged in two kidney-shaped lights 101 of cover 3, these lights 101 being made in flanges 104 generally oriented perpendicular to the plane of the cover.

Un fermoir 105 est prévu de côté opposé au flasque 104 pour maintenir le couvercle en position de fermeture, de façon connue en soi.A clasp 105 is provided on the side opposite the flange 104 for maintain the cover in the closed position, in a manner known in oneself.

Lorsque le boítier est ouvert, comme représenté sur la figure 13, les extrémités de l'axe 100 se situent au voisinage des extrémités 102 des lumières 101 qui sont les plus proches du dessus du couvercle.When the case is open, as shown in the figure 13, the ends of the axis 100 are located in the vicinity of the ends 102 of the lights 101 which are closest to the top of the cover.

L'axe 100 reste dans la même position relativement aux lumières 101 durant le début de la phase de fermeture du couvercle, tant que ce dernier ne prend pas appui sur l'organe d'étanchéité J, comme illustré sur la figure 14.The axis 100 remains in the same position relative to the lights 101 during the start of the lid closing phase, as long as this the latter does not bear on the sealing member J, as illustrated in Figure 14.

Cet organe d'étanchéité J peut être l'un quelconque des organes d'étanchéité précédemment décrits, et on ne l'a représenté sur les figures 13 à 15 que de façon très schématique.This sealing member J can be any one of the members previously described, and is only shown in the Figures 13 to 15 only very schematically.

Lorsque le couvercle 3 prend appui sur l'organe d'étanchéité J, la rotation du couvercle s'accompagne d'un glissement de l'axe 100 dans les lumières 101 vers les extrémités 103 les plus éloignées du dessus du couvercle, de sorte que ce dernier vient appuyer de manière sensiblement uniforme sur l'organe d'étanchéité J.When the cover 3 bears on the sealing member J, the rotation of the cover is accompanied by a sliding of the axis 100 in the lights 101 towards the ends 103 furthest from the above the cover, so that it comes to rest so substantially uniform on the sealing member J.
