Pour obtenir une étanchéité suffisante aux impuretés et aux fluides entre les milieux interne et externe dudit boîtier, il est recommandé d'utiliser un joint d'étanchéité, en particulier s'il s'agit d'un produit cosmétique comprenant une composition volatile et/ou humide. En général, le joint d'étanchéité est disposé entre la base et le couvercle et il subit un écrasement lorsque le boîtier est en position fermée.To obtain a sufficient seal against impurities and fluids between the internal and external media of said housing, it is recommended to use a seal, in particular if it is a cosmetic product comprising a volatile composition and / or wet. In general, the gasket is disposed between the base and the cover and is crushed when the housing is in the closed position.

Généralement, le verrouillage se fait par un système de verrouillage, tel qu'un bouton poussoir, en un point unique placé sur l'avant du boîtier. La pression exercée sur le joint n'est alors pas uniforme sur toute la surface du joint, notamment à l'arrière du boîtier. L'étanchéité n'est alors pas suffisamment efficace et le produit cosmétique risque de se dégrader rapidement ou de couler.
De plus, dans ce type de boîtier, la présence du joint crée une pression supplémentaire, le verrouillage/déverrouillage peut ainsi être plus difficile à obtenir.Generally, the locking is done by a locking system, such as a push button, at a single point placed on the front of the case. The pressure exerted on the seal is then not uniform over the entire surface of the seal, in particular at the rear of the housing. The seal is then not sufficiently effective and the cosmetic product runs the risk of rapidly deteriorating or of leaking.
In addition, in this type of housing, the presence of the seal creates additional pressure, locking / unlocking can thus be more difficult to obtain.

Dans le cas, par exemple, de boîtiers fermés par vissage, lorsque le boîtier passe de la position ouverte à la position fermée et inversement, cela entraîne notamment un frottement sur le joint d'étanchéité. Après plusieurs ouverture/fermeture, on observe une usure prématurée du joint, l'étanchéité est détériorée et le boîtier n'est plus suffisamment étanche. Le produit cosmétique risque alors un vieillissement accéléré. De plus, il n'est pas possible de réutiliser le boîtier, une fois le produit cosmétique terminé car l'étanchéité n'est plus effective.
Le document EP 3 015 019 A1 divulgue un boîtier pour produit cosmétique comprenant une base, un couvercle et un joint d'étanchéité.In the case, for example, of cases closed by screwing, when the case goes from the open position to the closed position and vice versa, this leads in particular to friction on the seal. After several opening / closing, premature wear of the seal is observed, the seal has deteriorated and the housing is no longer sufficiently waterproof. The cosmetic product then risks accelerated aging. In addition, it is not possible to reuse the case once the cosmetic product is finished because the seal is no longer effective.
The document EP 3 015 019 A1 discloses a cosmetic product case comprising a base, a cover and a seal.

Il existe donc un besoin d'un boîtier pour produit cosmétique permettant de résoudre les inconvénients précédents et qui soit de conception simple et facile d'utilisation.There is therefore a need for a casing for a cosmetic product which makes it possible to resolve the above drawbacks and which is of simple design and easy to use.

Résumé de l'inventionSummary of the invention

A cet effet, la présente invention propose un boîtier cosmétique comprenant une base, un couvercle, un joint d'étanchéité et un moyen de fermeture/ouverture.
La base et le couvercle sont articulés l'un par rapport à l'autre via une liaison pivot. Le boîtier est apte à occuper deux positions distinctes, une position fermée dans laquelle le couvercle est maintenu en position sur la base par le moyen de fermeture/ouverture et une position ouverte dans laquelle le couvercle est libre de pivoter par rapport à la base.
Ledit moyen de fermeture/ouverture comprend :

  • une pièce additionnelle qui est en liaison glissière ou en liaison pivot avec le couvercle,
  • une pluralité de moyens de verrouillage solidaires de la pièce additionnelle
    • respectivement de la base, lesdits moyens de verrouillage étant conçus pour coopérer, chacun, avec un logement prévu dans/sur la base - respectivement dans/sur la pièce additionnelle, la pluralité de moyens de verrouillage formant, avec lesdits logements, un verrouillage multipoints.
To this end, the present invention provides a cosmetic case comprising a base, a cover, a seal and a closing / opening means.
The base and the cover are articulated with respect to each other via a pivot connection. The housing is able to occupy two distinct positions, a closed position in which the cover is held in position on the base by the closing / opening means and an open position in which the cover is free to pivot relative to the base.
Said means of closing / opening comprises:
  • an additional part which is in sliding connection or in pivot connection with the cover,
  • a plurality of locking means integral with the additional part
    • respectively of the base, said locking means each being designed to cooperate with a housing provided in / on the base - respectively in / on the additional part, the plurality of locking means forming, with said housings, a multipoint locking.

Le joint d'étanchéité est prévu à la surface de la base - respectivement du couvercle

  • de manière à subir un écrasement par le couvercle - respectivement par la base - lorsque le boîtier est en position fermée.
The gasket is provided on the surface of the base - respectively of the cover
  • so as to be crushed by the cover - respectively by the base - when the housing is in the closed position.

Le verrouillage multipoints applique une pression suffisante sur le joint d'étanchéité lorsque le boîtier est en position fermée pour que l'étanchéité aux impuretés et aux fluides entre les milieux interne et externe dudit boîtier, en position fermée, soit totale aux conditions normales de température et de pression (CNTP). Autrement dit, le verrouillage multipoints est configuré pour appliquer une pression sur le joint d'étanchéité afin que, en position fermée, le boîtier soit fermé de manière étanche, c'est-à-dire avec une étanchéité aux impuretés et aux fluides entre les milieux interne et externe dudit boîtier qui soit totale aux conditions normales de température et de pression (CNTP).The multipoint locking applies sufficient pressure on the seal when the housing is in the closed position so that the impurity and fluid tightness between the internal and external media of said housing, in the closed position, is complete under normal temperature conditions. and pressure (CNTP). That is, multi-point locking is configured to apply pressure to the seal sealing so that, in the closed position, the housing is sealed, that is to say with impurity and fluid tightness between the internal and external media of said housing which is complete under normal temperature conditions and pressure (CNTP).

Contrairement au boîtier classique, le boîtier selon l'invention comprend une pièce additionnelle mobile par rapport au couvercle.Unlike the conventional housing, the housing according to the invention comprises an additional movable part relative to the cover.

D'une part, cette pièce additionnelle permet l'utilisation d'un verrouillage multipoints. Un tel verrouillage multipoints permet une répartition de la pression exercée sur le joint. L'étanchéité est ainsi effective et suffisante en tout point du joint aussi bien pour des particules de poussière que pour un liquide.On the one hand, this additional part allows the use of a multi-point locking. Such a multipoint locking allows a distribution of the pressure exerted on the seal. The seal is thus effective and sufficient at all points of the seal, both for dust particles and for a liquid.

D'autre part, la présence de la pièce additionnelle permet une ouverture du boîtier en appliquant une force plus importante, on peut ainsi ajouter un joint d'étanchéité sans que cela ne complique le verrouillage et le déverrouillage du boîtier.On the other hand, the presence of the additional part allows the housing to be opened by applying a greater force; it is thus possible to add a seal without this complicating the locking and unlocking of the housing.

Par ailleurs, la présence de la pièce additionnelle évite d'avoir un frottement entre le couvercle et la base. Ainsi, le passage de la position fermée à la position ouverte du boîtier et inversement, n'entraîne pas une usure prématurée du joint d'étanchéité. Le produit cosmétique ne risque donc pas d'être détérioré prématurément.
Par ailleurs, une fois le produit cosmétique terminé, l'étanchéité est toujours efficace et le boîtier reste opérationnel pour recevoir une dose de produit cosmétique supplémentaire, pour être rechargé en produit cosmétique.Furthermore, the presence of the additional part prevents friction between the cover and the base. Thus, the passage from the closed position to the open position of the housing and vice versa, does not lead to premature wear of the seal. The cosmetic product therefore does not run the risk of being deteriorated prematurely.
Furthermore, once the cosmetic product is finished, the seal is still effective and the box remains operational to receive an additional dose of cosmetic product, to be recharged with cosmetic product.

Description détailléedetailed description

L'invention concerne un boîtier 1 pour produit cosmétique comprenant :

  • une base 3,
  • un couvercle 5, et
  • un moyen de fermeture/ouverture 7.
The invention relates to a case 1 for a cosmetic product comprising:
  • a base 3,
  • a cover 5, and
  • a means of closing / opening 7.

Dans la description qui va suivre, on se réfère au trièdre X, Y, Z représenté sur les différentes figures. L'axe X est la direction principale d'extension longitudinale du boîtier 1, dite direction principale, l'axe Z est un axe orthogonal à l'axe X et parallèle au plan défini par un fond du boîtier 1 et parallèle à l'axe de rotation du couvercle 5 et enfin l'axe Y est un axe orthogonal aux axes X et Z.In the description which follows, reference is made to the trihedron X, Y, Z shown in the various figures. The X axis is the main direction of longitudinal extension of the housing 1, called the main direction, the Z axis is an axis orthogonal to the X axis and parallel to the plane defined by a bottom of the housing 1 and parallel to the axis of rotation of the cover 5 and finally the Y axis is an axis orthogonal to the X and Z axes.

A titre non limitatif, les termes « supérieur » et « haut » ou « inférieur » et « bas » sont utilisés en référence à l'axe X.
Les termes « intérieur » et « interne » sont utilisés par rapport au boîtier 1 pour désigner un élément dirigé vers le centre du boîtier 1 ou situé dans le boîtier 1 et les termes « extérieur » et « externe » sont utilisés par rapport au boîtier 1 pour désigner un élément dirigé vers l'extérieur du boîtier 1 ou situé en dehors du boîtier 1.
Les termes « avant » et « arrière » sont utilisés en référence à l'axe Y.Without limitation, the terms “upper” and “top” or “lower” and “bottom” are used with reference to the X axis.
The terms “inside” and “internal” are used with respect to the housing 1 to denote an element directed towards the center of the housing 1 or located in the housing 1 and the terms “outside” and “external” are used with respect to the housing 1 to designate an element directed towards the outside of the housing 1 or located outside the housing 1.
The terms "front" and "rear" are used in reference to the Y axis.

La base 3 et le couvercle 5 sont articulés l'un par rapport à l'autre via une liaison pivot.The base 3 and the cover 5 are articulated with respect to one another via a pivot connection.

Le boîtier 1 est apte à occuper au moins deux positions distinctes :

  • une position fermée (visible aux figures 2 et 8) dans laquelle le couvercle 5 est maintenu en position sur la base 3 par le moyen de fermeture/ouverture 7, et
  • une position ouverte (visible aux figures 4, 5, 7 et 10) dans laquelle le couvercle 5 est libre de pivoter par rapport à la base 3.
The housing 1 is able to occupy at least two distinct positions:
  • a closed position (visible to figures 2 and 8 ) in which the cover 5 is held in position on the base 3 by the closing / opening means 7, and
  • an open position (visible to figures 4 , 5 , 7 and 10 ) in which the cover 5 is free to pivot relative to the base 3.

La liaison pivot est obtenue par une partie du couvercle 5, dite articulation 9, lui permettant de pivoter par rapport à la base 3 lorsque le boîtier 1 est en position ouverte.The pivot connection is obtained by a part of the cover 5, called the articulation 9, allowing it to pivot relative to the base 3 when the housing 1 is in the open position.

Le moyen de fermeture/ouverture 7 comprend :

  • une pièce additionnelle 11 qui est en liaison glissière ou en liaison pivot avec le couvercle 5, et
  • une pluralité de moyens de verrouillage 13 solidaires de la pièce additionnelle 11 - respectivement de la base 3.
The closing / opening means 7 comprises:
  • an additional part 11 which is in a sliding connection or in a pivot connection with the cover 5, and
  • a plurality of locking means 13 integral with the additional part 11 - respectively with the base 3.

Les moyens de verrouillage 13 sont conçus pour coopérer, chacun, avec un logement 15 prévu dans/sur la base 3 - respectivement dans/sur la pièce additionnelle 11. La pluralité de moyens de verrouillage 13 forme, avec lesdits logements 15, un verrouillage multipoints.The locking means 13 are designed to cooperate, each with a housing 15 provided in / on the base 3 - respectively in / on the additional part 11. The plurality of locking means 13 form, with said housings 15, a multipoint locking. .

Chaque coopération entre l'un des moyens de verrouillage 13 et le logement 15 qui lui est associé détermine l'un des points de verrouillage formant ledit verrouillage multipoints.Each cooperation between one of the locking means 13 and the housing 15 which is associated with it determines one of the locking points forming said multipoint locking.

Ainsi, le boîtier 1 selon l'invention présente deux modes de réalisation principaux :

  • un premier mode de réalisation principal représenté aux figures 1 à 5d dans lequel la pièce additionnelle 11 est en liaison glissière avec le couvercle 5,
  • un deuxième mode de réalisation principal représenté aux figures 6 à 12 dans lequel la pièce additionnelle 11 est en liaison pivot avec le couvercle 5.
Thus, the box 1 according to the invention has two main embodiments:
  • a first main embodiment shown in figures 1 to 5d in which the additional part 11 is in sliding connection with the cover 5,
  • a second main embodiment shown in figures 6 to 12 in which the additional part 11 is in a pivot connection with the cover 5.

Chacun des deux modes de réalisation principaux peut présenter des variantes de réalisation. Nous décrirons par la suite certaines de ces variantes.Each of the two main embodiments can have variant embodiments. We will describe some of these variants later.

Par ailleurs, le boîtier 1 cosmétique comprend un joint d'étanchéité 21.Furthermore, the cosmetic case 1 comprises a seal 21.

Le joint d'étanchéité 21 est prévu à la surface de la base 3 - respectivement du couvercle 5 - de manière à subir un écrasement par le couvercle 5 - respectivement par la base 3 - lorsque le boîtier 1 est en position fermée.The seal 21 is provided on the surface of the base 3 - respectively of the cover 5 - so as to be crushed by the cover 5 - respectively by the base 3 - when the housing 1 is in the closed position.

Le verrouillage multipoints est configuré pour appliquer une pression suffisante sur le joint d'étanchéité 21 lorsque le boîtier 1 est en position fermée de manière que l'étanchéité aux impuretés et aux fluides entre les milieux interne et externe dudit boîtier 1 soit totale aux conditions normales de température et de pression (CNTP), c'est à dire une température de 0°C et une pression de 1 atm.The multipoint locking is configured to apply sufficient pressure to the seal 21 when the housing 1 is in the closed position so that the impurity and fluid tightness between the internal and external media of said housing 1 is total under normal conditions. temperature and pressure (CNTP), i.e. a temperature of 0 ° C and a pressure of 1 atm.

On entend par « impuretés » principalement des impuretés solides telles que des particules, de la poussière ou encore de la poudre de produit cosmétique.
On entend par « fluide » un liquide ou un gaz provenant du produit cosmétique ou de l'extérieur du boîtier. Il peut s'agir par exemple d'un solvant, d'un produit volatile, du produit cosmétique en lui-même, de l'eau, de l'oxygène, etc.The term “impurities” is understood to mean mainly solid impurities such as particles, dust or even powder of a cosmetic product.
The term “fluid” is understood to mean a liquid or a gas originating from the cosmetic product or from the exterior of the housing. It can be, for example, a solvent, a volatile product, the cosmetic product itself, water, oxygen, etc.

Le joint d'étanchéité 21 peut être rapporté à la surface de la base 3 - réciproquement à la surface du couvercle 5, maintenu en position par collage surfacique ou encore surmoulé avec la base 3 - réciproquement avec le couvercle 5.The seal 21 can be attached to the surface of the base 3 - reciprocally to the surface of the cover 5, held in position by surface bonding or else overmolded with the base 3 - conversely with the cover 5.

Dans certaines variantes, le joint d'étanchéité 21 peut être un moyen d'assistance à l'ouverture du boîtier 1.In some variants, the seal 21 can be a means of assisting the opening of the housing 1.

De façon avantageuse, le joint d'étanchéité 21 est en élastomère, tel que du caoutchouc, du silicone, en polyéthylène expansé, tel que le Tresylene® ou tout autre matériau permettant de garantir l'étanchéité du boîtier.Advantageously, the seal 21 is made of an elastomer, such as rubber, silicone, expanded polyethylene, such as Tresylene® or any other material making it possible to guarantee the tightness of the housing.

De façon avantageuse, l'actionnement du moyen de fermeture/ouverture 7 se fait par la mise en mouvement de la pièce additionnelle 11 par rapport au couvercle 5 de manière à engager/dégager les moyens de verrouillage 13 de leur logement 15 respectif.Advantageously, the actuation of the closing / opening means 7 is effected by setting the additional part 11 in motion relative to the cover 5 so as to engage / disengage the locking means 13 from their respective housing 15.

Ainsi, le passage de la position ouverte vers la position fermée du boîtier 1, et réciproquement, peut se faire en appliquant une force importante si cela est nécessaire. La présence d'un joint d'étanchéité 21 est donc possible sans gêner l'engagement/dégagement des moyens de verrouillage 13. De plus, ce système n'entraine pas de frottement sur le joint d'étanchéité 21.Thus, the passage from the open position to the closed position of the housing 1, and vice versa, can be done by applying a large force if this is necessary. necessary. The presence of a seal 21 is therefore possible without hindering the engagement / release of the locking means 13. In addition, this system does not cause friction on the seal 21.

De préférence, la pièce additionnelle 11 est conçue pour rendre inaccessible au toucher la quasi-totalité du couvercle 5 à un utilisateur extérieur lorsque le boîtier 1 est en position fermée, l'articulation 9 étant l'unique partie du couvercle 5 accessible au toucher pour un utilisateur extérieur lorsque le boîtier 1 est en position fermée. Autrement dit, la pièce additionnelle 11 est conçue de manière à envelopper la totalité du couvercle 5, à l'exception de ladite articulation 9, c'est ce que l'on entend par « quasi-totalité du couvercle 5 ».Preferably, the additional part 11 is designed to make almost all of the cover 5 inaccessible to the touch to an external user when the housing 1 is in the closed position, the articulation 9 being the only part of the cover 5 accessible to the touch for an external user when the housing 1 is in the closed position. In other words, the additional part 11 is designed so as to envelop the entire cover 5, with the exception of said articulation 9, this is what is meant by “almost all of the cover 5”.

On obtient ainsi un boîtier 1 dans lequel quasiment seules la base 3 et la pièce additionnelle 11 sont accessibles. Cela procure une apparence esthétique épurée et agréable.A housing 1 is thus obtained in which almost only the base 3 and the additional part 11 are accessible. This provides a clean and pleasing aesthetic appearance.

De plus, en empêchant l'accès du couvercle 5 à l'utilisateur en position fermée du boîtier 1, celui-ci peut facilement mettre en mouvement la pièce additionnelle 11 par rapport au couvercle 5, sans que le mouvement ne soit gêné en maintenant par mégarde le couvercle 5, par exemple.In addition, by preventing access of the cover 5 to the user in the closed position of the housing 1, the latter can easily set the additional part 11 in motion with respect to the cover 5, without the movement being hampered by maintaining by mistakenly the cover 5, for example.

Cela est particulièrement avantageux dans le cas de boîtiers fins pour lesquels la prise en main et la mise en mouvement uniquement de la pièce additionnelle 11 peuvent être délicates si le couvercle 5 est accessible.This is particularly advantageous in the case of thin housings for which the handling and setting in motion only of the additional part 11 can be difficult if the cover 5 is accessible.

Autrement dit, le boîtier 1 peut être ouvert en poussant aussi bien sur la surface supérieure que sur l'arête de la pièce additionnelle 11 ou sur son épaisseur. La prise en main est ainsi plus facile et on facilite la gestuelle. Les doigts de l'utilisateur risquent moins de glisser par rapport à un système où l'ouverture se fait par un coulissement en appuyant uniquement sur la surface supérieure d'une pièce.In other words, the housing 1 can be opened by pushing both on the upper surface and on the edge of the additional part 11 or on its thickness. The handling is thus easier and the gestures are facilitated. The user's fingers are less likely to slip compared to a system where opening is by sliding by pressing only on the top surface of a part.

Par ailleurs, le fait d'utiliser une pièce additionnelle 11 pour le verrouillage/déverrouillage du boîtier 1 et de placer cette pièce 11 de manière à ce que le couvercle 5 soit quasiment inaccessible à l'utilisateur permet de ne pas encombrer la face interne du couvercle 5 et d'y disposer un miroir, par exemple.Furthermore, the fact of using an additional part 11 for locking / unlocking the housing 1 and placing this part 11 so that that the cover 5 is almost inaccessible to the user makes it possible not to encumber the internal face of the cover 5 and to have a mirror there, for example.

De préférence, les points de verrouillage déterminés par les moyens de verrouillage 13 sont régulièrement répartis sur le pourtour interne de la pièce additionnelle 11 - respectivement sur la périphérie de la base 3 - en étant, chacun, destiné à coopérer avec un logement 15 dédié.Preferably, the locking points determined by the locking means 13 are regularly distributed over the internal periphery of the additional part 11 - respectively on the periphery of the base 3 - each being intended to cooperate with a dedicated housing 15.

Le verrouillage multipoints du boîtier 1 comporte au moins deux points de verrouillage, de préférence quatre points de verrouillage ou plus.
Avantageusement, le nombre de points de verrouillage est un nombre pair.The multi-point locking of the housing 1 has at least two locking points, preferably four or more locking points.
Advantageously, the number of locking points is an even number.

De préférence, les logements 15 sont prévus dans la base 3 ou la pièce additionnelle 11 et sont régulièrement répartis.Preferably, the housings 15 are provided in the base 3 or the additional part 11 and are regularly distributed.

Chacun des logements 15 est, par exemple, un creux, tel qu'un cran, conçu dans la base 3 ou la pièce additionnelle 11 de manière à retenir le moyen de verrouillage 13 correspondant et maintenir le boîtier 1 en position fermée.Each of the housings 15 is, for example, a hollow, such as a notch, designed in the base 3 or the additional part 11 so as to retain the corresponding locking means 13 and maintain the housing 1 in the closed position.

Les logements 15 peuvent également être prévus sur la base 3 ou la pièce additionnelle 11. Chacun des logements 15 est alors, par exemple, sous la forme d'une zone en relief configurée pour recevoir le moyen de verrouillage 13 correspondant et le retenir engagé pour maintenir le boîtier 1 en positon fermée.
On entend par « en relief » une boursouflure, un élément faisant sailli de la base 3 ou de la pièce additionnelle 11, tel qu'un moulage en relief, un élément rapporté (surmoulé ou collé) dans lequel un logement 15 est formé pour recevoir le moyen de verrouillage 13.The housings 15 can also be provided on the base 3 or the additional part 11. Each of the housings 15 is then, for example, in the form of a raised zone configured to receive the corresponding locking means 13 and keep it engaged for keep the housing 1 in the closed position.
By "in relief" is meant a blister, an element projecting from the base 3 or from the additional part 11, such as a relief molding, an added element (overmolded or glued) in which a housing 15 is formed to receive the locking means 13.

Le boîtier 1 peut également comprendre un moyen d'assistance à l'ouverture du boîtier 1. Le moyen d'assistance peut se présenter sous la forme d'au moins un bourrelet de matière (non représenté) faisant sailli de la base 3 - respectivement du couvercle 5, en direction du couvercle 5 - respectivement de la base 3, au voisinage de ladite articulation 9.The housing 1 can also include a means for assisting the opening of the housing 1. The means for assisting can be in the form of at least one bead of material (not shown) projecting from the base 3 - respectively. of the cover 5, in the direction of the cover 5 - respectively of the base 3, in the vicinity of said articulation 9.

Ledit moyen d'assistance à l'ouverture du boîtier 1 est destiné à écarter le couvercle 5 de la base 3 lors du passage du boîtier 1 de la position fermée à la position ouverte, en maintenant une préouverture de quelques degrés, par exemple une préouverture comprise entre 0,5 et 5°, de préférence de 3°.Said means for assisting the opening of the housing 1 is intended to move the cover 5 away from the base 3 during the passage of the housing 1 from the closed position to the open position, by maintaining a pre-opening of a few degrees, for example a pre-opening. between 0.5 and 5 °, preferably 3 °.

De façon avantageuse, le joint d'étanchéité 21 peut jouer le rôle de moyen d'assistance à l'ouverture du boîtier 1.Advantageously, the seal 21 can act as a means of assisting the opening of the housing 1.

Dans le premier mode de réalisation représenté aux figures 1 à 5d, le boîtier 1 est de forme parallélépipédique, et plus précisément de forme carrée. Il comprend un côté arrière AR sur lequel est positionnée la liaison pivot, un côté avant AV opposé au côté arrière AR et deux côtés latéraux opposés s'étendant du côté arrière AR vers le côté avant AV. Une forme rectangulaire ou toute autre forme, par exemple globalement circulaire, pourraient être envisagée.In the first embodiment shown in figures 1 to 5d , the housing 1 is of parallelepiped shape, and more precisely of square shape. It comprises a rear rear side on which the pivot link is positioned, a front front side opposite to the rear rear side and two opposite lateral sides extending from the rear rear side towards the front front side. A rectangular shape or any other shape, for example generally circular, could be envisaged.

Dans certaines variantes, le côté avant AV peut comprendre une zone de préhension 22, visible à la figure 5c par exemple, de manière à faciliter l'ouverture du couvercle 5.In some variants, the front side AV may include a gripping area 22, visible from the figure 5c for example, so as to facilitate the opening of the cover 5.

Dans ce premier mode de réalisation, la pièce additionnelle 11 est en liaison glissière avec le couvercle 5.In this first embodiment, the additional part 11 is in sliding connection with the cover 5.

La liaison glissière entre la pièce additionnelle 11 et le couvercle 5 est assurée par une coopération de formes techniques présentes, d'une part sur la périphérie externe du couvercle 5, et d'autre part sur un pourtour interne de la pièce additionnelle 11.The sliding connection between the additional part 11 and the cover 5 is ensured by a cooperation of technical forms present, on the one hand on the outer periphery of the cover 5, and on the other hand on an internal periphery of the additional part 11.

Dans ce mode de réalisation, chacun des cotés latéraux du couvercle 5 comprend deux nervures 25 configurées pour coopérer avec une rainure 27 s'étendant sur toute la longueur de chacun des côtés latéraux de la pièce additionnelle 11 (figures 5b et 5c). Autrement dit, les rainures 27 de la pièce additionnelle 11 servent de glissières aux nervures 25 du couvercle 5, la pièce additionnelle 11 pouvant ainsi effectuer un mouvement de translation selon l'axe Y par rapport au couvercle 5.In this embodiment, each of the lateral sides of the cover 5 comprises two ribs 25 configured to cooperate with a groove 27 extending over the entire length of each of the lateral sides of the additional part 11 ( figures 5b and 5c ). In other words, the grooves 27 of the additional part 11 serve as guides for the ribs 25 of the cover 5, the additional part 11 thus being able to perform a translational movement along the Y axis relative to the cover 5.

De préférence, les moyens de verrouillage 13 sont des crochets.Preferably, the locking means 13 are hooks.

Ce mouvement de translation permet l'actionnement du moyen de fermeture/ouverture 7 et donc d'engager/dégager les crochets 13 de leur logement 15 correspondant. Pour engager/dégager le crochet 13 du logement 15, la pièce additionnelle effectue également un mouvement de translation par rapport à la base.This translational movement allows the actuation of the closing / opening means 7 and therefore to engage / disengage the hooks 13 from their corresponding housing 15. To engage / disengage the hook 13 from the housing 15, the additional part also performs a translational movement relative to the base.

Le couvercle 5 peut aussi comprendre au moins un évidement 28 de manière à rendre flexible la partie du couvercle 5 qui porte les nervures 25 (figures 1 et 5d). Cette flexibilité facilite l'assemblage du couvercle 5 dans la pièce additionnelle 11, notamment l'assemblage des nervures 25 à l'intérieur des rainures 27.The cover 5 can also comprise at least one recess 28 so as to make flexible the part of the cover 5 which carries the ribs 25 ( figures 1 and 5d ). This flexibility facilitates the assembly of the cover 5 in the additional part 11, in particular the assembly of the ribs 25 inside the grooves 27.

De préférence, le ou les évidements 28 sont traversants et s'étendent sur la ou les parties du couvercle 5 adjacentes aux nervures 25.Preferably, the recess (s) 28 are through and extend over the part (s) of the cover 5 adjacent to the ribs 25.

Dans la variante de réalisation représentée notamment à la figure 5d, le couvercle comprend quatre évidements 28. Autrement dit, ces évidements 28 donnent de l'élasticité aux parois supportant les nervures 25 de manière à faciliter l'insertion, notamment par emboitage, de préférence par clipsage, de la partie du couvercle 5 à l'intérieur de la pièce additionnelle 11.In the variant embodiment shown in particular in figure 5d , the cover comprises four recesses 28. In other words, these recesses 28 give elasticity to the walls supporting the ribs 25 so as to facilitate the insertion, in particular by fitting, preferably by clipping, of the part of the cover 5 to the interior of additional room 11.

Dans ce mode de réalisation, l'articulation 9 est ici située sur le côté arrière AR du couvercle 5. Il s'agit d'une extension de matière, ici sous la forme d'un parallélépipède rectangle 9 venant se loger, lors de l'assemblage du couvercle 5 à la base 3, dans un logement 29 disposé à l'arrière de la base 3 et formé entre deux extensions 30 de la base 3 situées vers l'extérieur du boîtier 1.In this embodiment, the articulation 9 is here located on the rear side AR of the cover 5. It is an extension of material, here in the form of a rectangular parallelepiped 9 coming to be received, during the assembly of the cover 5 to the base 3, in a housing 29 arranged at the rear of the base 3 and formed between two extensions 30 of the base 3 located towards the outside of the housing 1.

L'extension de matière ou articulation 9 est reliée à la base 3 par l'intermédiaire d'au moins une broche 31 reliant la base 3 et l'articulation 9 du couvercle 5. Ici, l'articulation 9 comprend deux trous 33a situé de part et d'autre de l'articulation 9 et la broche correspond à deux goupilles 31.The extension of material or articulation 9 is connected to the base 3 by means of at least one pin 31 connecting the base 3 and the articulation 9 of the cover 5. Here, the articulation 9 comprises two holes 33a located on either side of the joint 9 and the pin corresponds to two pins 31.

Chacune des goupilles 31 présente une première extrémité insérée dans un des trous 33a de l'articulation 9 et une seconde extrémité insérée dans un trou 33b formé sur le côté arrière AR de la base 3 au niveau de chacune des extensions 30. Les goupilles 31 déterminent l'axe de rotation du couvercle 5, qui est parallèle à l'axe Z. Tout autre moyen permettant de remplir cette fonction sera compris dans l'invention.Each of the pins 31 has a first end inserted into one of the holes 33a of the joint 9 and a second end inserted into a hole 33b formed on the rear side AR of the base 3 at each of the extensions 30. The pins 31 determine the axis of rotation of the cover 5, which is parallel to the Z axis. Any other means making it possible to fulfill this function will be included in the invention.

On peut également imaginer dans un mode de réalisation non représenté, que l'unique partie du couvercle 5 accessible au toucher pour un utilisateur extérieur lorsque le boîtier 1 est en position fermée, dite articulation 9, soit deux extensions de matière du couvercle 5 situées vers l'extérieur du boîtier 1 sur le côté arrière AR et formant un logement dans lequel vient se placer une extension de la base 3, par exemple sous la forme d'un parallélépipède rectangle, ou encore d'un cylindre, chacune des extensions du couvercle 5 et de la base 3 étant percées pour faire passer au moins une goupille 31 pour réaliser la liaison pivot entre la base 3 et le couvercle 5. Autrement dit, il s'agit d'un système inverse à celui représenté ici.One can also imagine, in an embodiment not shown, that the only part of the cover 5 accessible to the touch for an external user when the housing 1 is in the closed position, known as the articulation 9, that is to say two extensions of material of the cover 5 located towards the outside of the housing 1 on the rear side AR and forming a housing in which is placed an extension of the base 3, for example in the form of a rectangular parallelepiped, or even of a cylinder, each of the extensions of the cover 5 and the base 3 being pierced to pass at least one pin 31 to achieve the pivot connection between the base 3 and the cover 5. In other words, it is a reverse system to that shown here.

Selon l'invention, le boîtier 1 comprend un joint d'étanchéité 21 prévu, ici, à la surface interne du couvercle 5 de manière à subir un écrasement par la base 3 lorsque le boîtier 1 est en position fermée.According to the invention, the housing 1 comprises a seal 21 provided here on the internal surface of the cover 5 so as to undergo crushing by the base 3 when the housing 1 is in the closed position.

Dans ce mode de réalisation, le joint d'étanchéité 21 est un cordon de matière inséré dans une rainure 23 formée sur toute la périphérie de la surface interne du couvercle 5 de manière à obtenir une étanchéité sur tout le pourtour du boîtier 1.In this embodiment, the seal 21 is a bead of material inserted into a groove 23 formed over the entire periphery of the internal surface of the cover 5 so as to obtain a seal over the entire periphery of the housing 1.

Dans ce mode de réalisation, les moyens de verrouillage sont quatre crochets 13 répartis deux à deux sur les côtés latéraux de la pièce additionnelle 11 coopérant avec quatre logements 15 répartis deux à deux sur les côtés latéraux de la base 3.In this embodiment, the locking means are four hooks 13 distributed two by two on the lateral sides of the additional part 11 cooperating with four housings 15 distributed two by two on the lateral sides of the base 3.

Les logements 15 sont en forme de L et comprennent une entrée 15b pour permettre l'engagement du crochet 13 correspondant et une zone de verrouillage 15c pour permettre le blocage du crochet après mouvement en translation de la pièce additionnelle 11.The housings 15 are L-shaped and include an inlet 15b to allow the engagement of the corresponding hook 13 and a locking zone 15c to allow the locking of the hook after translational movement of the additional part 11.

De manière avantageuse, les logements 15 présentent une saillie 15a configurée pour former la zone de verrouillage 15c et retenir le crochet 13 et maintenir le boîtier 1 en position fermée (figures 1, 3 et 5a).Advantageously, the housings 15 have a projection 15a configured to form the locking zone 15c and retain the hook 13 and maintain the housing 1 in the closed position ( figures 1 , 3 and 5a ).

Dans ce mode de réalisation, les crochets 13 sont issus de matière de la pièce additionnelle 11. De préférence, les crochets 13 sont rigides pour pouvoir notamment contenir la pression du joint.In this embodiment, the hooks 13 are made from the material of the additional part 11. Preferably, the hooks 13 are rigid in order in particular to be able to contain the pressure of the seal.

Ils peuvent également présenter une forme technique comprenant une pente de manière à amplifier la force de fermeture lors du verrouillage du boîtier 1 et à faciliter l'entrée de chacun des crochets 13 dans le logement 15 correspondant lors du passage de la position ouverte à la position fermée du boîtier 1 et son verrouillage. On entend par « crochet rigide » un élément qui résiste à une pression, qui ne se plie pas, ne se déforme pas sous la pression.They can also have a technical form comprising a slope so as to amplify the closing force when locking the housing 1 and to facilitate the entry of each of the hooks 13 into the corresponding housing 15 when passing from the open position to the position. closed of the housing 1 and its locking. The term “rigid hook” is understood to mean an element which resists pressure, which does not bend or deform under pressure.

Dans d'autres variantes de réalisation non représentées, on peut également envisager que les moyens de verrouillage 13 soient solidaires de la base 3 et que les logements 15 soient prévus dans la pièce additionnelle 11.
On peut également envisager que les logements 15 soient conçus sur la base 3 ou la pièce additionnelle 11.In other variant embodiments not shown, it is also conceivable that the locking means 13 are integral with the base 3 and that the housings 15 are provided in the additional part 11.
It is also conceivable that the housings 15 are designed on the base 3 or the additional room 11.

Dans ce mode de réalisation, le moyen d'assistance à l'ouverture du boîtier 1 est le joint d'étanchéité 21 prévu à la surface du couvercle 5. Le joint est compressé lorsque le boîtier 1 est fermé et il se détend lorsque les moyens de verrouillage 13 sont dégagés permettant ainsi une préouverture du boîtier 1 de quelques degrés, de préférence de 3 ° (figure 3).In this embodiment, the means for assisting the opening of the case 1 is the seal 21 provided on the surface of the cover 5. The seal is compressed when the case 1 is closed and it expands when the means locking mechanism 13 are released thus allowing pre-opening of the housing 1 by a few degrees, preferably by 3 ° ( figure 3 ).

Le mécanisme d'ouverture va maintenant être décrit en référence aux figures 2 à 4.The opening mechanism will now be described with reference to figures 2 to 4 .

Dans un premier temps, l'utilisateur dégage les crochets 13 de la pièce additionnelle 11 insérés dans leur logement 15 prévu sur la base 3 par un mouvement de translation selon l'axe Y de la pièce additionnelle 11 par rapport au couvercle 5 et par rapport à la base 3. Autrement dit, en position fermée du boîtier 1, les crochets 13 sont bloqués au niveau de la zone de verrouillage 15c de leur logement 15 par la saillie 15a.First, the user releases the hooks 13 of the additional part 11 inserted in their housing 15 provided on the base 3 by a translational movement along the Y axis of the additional part 11 with respect to the cover 5 and with respect to at the base 3. In other words, in the closed position of the housing 1, the hooks 13 are blocked at the level of the locking zone 15c of their housing 15 by the projection 15a.

Lors du mouvement en translation de la pièce additionnelle, les crochets 13 se trouvent dans l'alignement de l'entrée 15b, comme cela est visible à la figure 3. Plus rien ne retient alors le boîtier en position fermée, les crochets 13 sont alors dégagés et le boîtier 1 s'ouvre comme cela est visible à la figure 3.During the translational movement of the additional part, the hooks 13 are in alignment with the entry 15b, as can be seen in figure 3 . More nothing then retains the housing in the closed position, the hooks 13 are then released and the housing 1 opens as can be seen at figure 3 .

L'ouverture du couvercle 5 est notamment facilitée par la présence du joint d'étanchéité 21 qui se détend et assure une préouverture du boîtier 1 d'environ 3°. L'utilisateur termine ensuite l'ouverture du boîtier 1 en pivotant le couvercle 5 assemblé à la pièce additionnelle 11 jusqu'à la position ouverte illustrée à la figure 4.The opening of the cover 5 is in particular facilitated by the presence of the seal 21 which relaxes and ensures a pre-opening of the housing 1 of approximately 3 °. The user then completes the opening of the housing 1 by pivoting the cover 5 assembled to the additional part 11 to the open position illustrated in figure 4 .

Dans le deuxième mode de réalisation représenté aux figures 6 à 12, le couvercle 5, est de forme circulaire et la pièce additionnelle 11 présente une forme globalement parallélépipédique.In the second embodiment shown in figures 6 to 12 , the cover 5, is circular in shape and the additional part 11 has a generally parallelepipedal shape.

Le boîtier 1 présente une partie arrière AR et une partie avant AV opposée à la partie arrière AR. Comme pour le premier mode de réalisation une zone de préhension (non représentée) pourrait être envisagée sur la partie avant AV du boîtier 1.
De même une forme circulaire pourrait également être envisagée pour la pièce additionnelle 11.The housing 1 has a rear part AR and a front part front opposite to the rear part AR. As for the first embodiment, a gripping zone (not shown) could be envisaged on the front part AV of the housing 1.
Similarly, a circular shape could also be considered for the additional part 11.

Dans ce deuxième mode de réalisation, la pièce additionnelle 11 est en liaison pivot avec le couvercle 5.In this second embodiment, the additional part 11 is in a pivot connection with the cover 5.

Comme pour la liaison glissière du premier mode de réalisation, la liaison pivot entre la pièce additionnelle 11 et le couvercle 5 est assurée par une coopération de formes techniques présentes, d'une part sur la périphérie externe du couvercle 5, et d'autre part sur un pourtour interne de la pièce additionnelle 11.As for the sliding connection of the first embodiment, the pivot connection between the additional part 11 and the cover 5 is ensured by a cooperation of technical forms present, on the one hand on the outer periphery of the cover 5, and on the other hand on an internal perimeter of the additional part 11.

Dans ce mode de réalisation, le pourtour interne de la pièce additionnelle 11 comprend des nervures 25, ici trois, régulièrement angulairement réparties et configurées pour coopérer avec des rainures 27, ici trois, s'étendant sur la périphérie externe du couvercle 5 et régulièrement angulairement réparties (figures 11 et 12).In this embodiment, the inner periphery of the additional part 11 comprises ribs 25, here three, regularly angularly distributed and configured to cooperate with grooves 27, here three, extending over the outer periphery of the cover 5 and regularly angularly distributed ( figures 11 and 12 ).

Les rainures 27 de la périphérie externe du couvercle 5 servent de chemin de guidage aux nervures 25 du pourtour interne de la pièce additionnelle 11. La pièce additionnelle 11 peut ainsi se déplacer par rapport au couvercle 5 selon un mouvement de rotation d'axe parallèle à l'axe X. Ce mouvement de rotation permet l'actionnement du moyen de fermeture/ouverture 7 et d'engager/dégager le crochet 13 du logement 15.The grooves 27 of the external periphery of the cover 5 serve as a guide path for the ribs 25 of the internal periphery of the additional part 11. The additional part 11 can thus move relative to the cover 5 according to a rotational movement with an axis parallel to the X axis. This rotational movement allows the actuation of the closing / opening means 7 and to engage / disengage the hook 13 from the housing 15.

Le système permettant la liaison pivot entre le couvercle 5 et la base 3 est similaire à celui du premier mode de réalisation.
L'articulation 9 du couvercle 5 est reliée à la base 3 par l'intermédiaire de deux goupilles 31 insérées dans des trous 33a, 33b de l'articulation 9 et de la base 3. Les goupilles 31 déterminent l'axe de rotation du couvercle 5, qui est parallèle à l'axe Z.The system allowing the pivot connection between the cover 5 and the base 3 is similar to that of the first embodiment.
The articulation 9 of the cover 5 is connected to the base 3 by means of two pins 31 inserted in holes 33a, 33b of the articulation 9 and of the base 3. The pins 31 determine the axis of rotation of the cover 5, which is parallel to the Z axis.

Dans ce deuxième mode de réalisation, le boîtier 1 comprend également un joint d'étanchéité 21 prévu à la surface interne du couvercle 5 de manière à subir un écrasement par la base 3 lorsque le boîtier 1 est en position fermée.In this second embodiment, the housing 1 also comprises a seal 21 provided on the internal surface of the cover 5 so as to undergo crushing by the base 3 when the housing 1 is in the closed position.

Dans ce mode de réalisation, les moyens de verrouillage sont également quatre crochets 13. Les crochets 13 sont issus de matière de la base 3 et sont régulièrement angulairement répartis sur celle-ci. Les crochets 13 coopèrent avec quatre logements 15 régulièrement angulairement répartis dans la pièce additionnelle 11.In this embodiment, the locking means are also four hooks 13. The hooks 13 are made from the material of the base 3 and are regularly angularly distributed over the latter. The hooks 13 cooperate with four housings 15 regularly angularly distributed in the additional part 11.

De préférence, les crochets 13 sont rigides et présentent une forme technique comprenant une pente de manière à pouvoir contenir la pression du joint d'étanchéité 21 et amplifier la force de fermeture lors du verrouillage du boîtier 1.Preferably, the hooks 13 are rigid and have a technical form comprising a slope so as to be able to contain the pressure of the seal 21 and to amplify the closing force when locking the housing 1.

Dans ce mode de réalisation, le couvercle 5 comprend avantageusement quatre encoches 24 régulièrement angulairement réparties pour permettre le passage des crochets 13 jusqu'à leur logement 15 correspondant prévu dans la pièce additionnelle 11, et/ou le dégagement des crochets 13 de leur logement 15.

Comme dans le premier mode de réalisation, le moyen d'assistance à l'ouverture du boîtier 1 est, ici, le joint d'étanchéité 21 prévu à la surface du couvercle 5. Le joint d'étanchéité 21 est compressé lorsque le boîtier 1 est fermé et il se détend lorsque les moyens de verrouillage 13 sont dégagés permettant ainsi une préouverture du boîtier 1 de quelques degrés, de préférence de 3° (figure 9).As in the first embodiment, the means for assisting the opening of the case 1 is, here, the seal 21 provided on the surface of the cover 5. The seal 21 is compressed when the case 1 is closed and it relaxes when the locking means 13 are released thus allowing a pre-opening of the housing 1 by a few degrees, preferably by 3 ° ( figure 9 ).

Le mécanisme d'ouverture va maintenant être décrit en référence aux figures 8 à 10.The opening mechanism will now be described with reference to figures 8 to 10 .

Le mécanisme d'ouverture est semblable à celui du premier mode de réalisation, seul le type de mouvement de la pièce additionnelle 11 par rapport au couvercle 5 diffère. En effet, dans le premier mode de réalisation, le mouvement est une translation selon l'axe Y alors que dans ce deuxième mode de réalisation, la pièce additionnelle 11 réalise un mouvement de rotation par rapport au couvercle 5.The opening mechanism is similar to that of the first embodiment, only the type of movement of the additional part 11 relative to the cover 5 differs. Indeed, in the first embodiment, the movement is a translation along the Y axis while in this second embodiment, the additional part 11 performs a rotational movement relative to the cover 5.

Dans un premier temps, l'utilisateur dégage les crochets 13 de la base 3 insérés dans leur logement 15 correspondant prévu sur la pièce additionnelle 11 par un mouvement de rotation d'axe parallèle à l'axe X de la pièce additionnelle 11 par rapport au couvercle 5 et par rapport à la base 3.First, the user releases the hooks 13 from the base 3 inserted into their corresponding housing 15 provided on the additional part 11 by a rotational movement with an axis parallel to the X axis of the additional part 11 with respect to the cover 5 and relative to the base 3.

En position fermée du boîtier 1, les crochets 13 sont maintenus dans les logements 15 par le couvercle 5 qui remplace la saillie 15a du premier mode de réalisation. Après rotation de la pièce additionnelle 11, les crochets 13 se trouvent alignés avec les encoches 24 du couvercle 5 et peuvent alors se dégager. Le boîtier 1 peut s'ouvrir comme cela est visible à la figure 9.In the closed position of the housing 1, the hooks 13 are held in the housings 15 by the cover 5 which replaces the projection 15a of the first embodiment.

The user can thus put on make-up wherever he is by looking at himself in the mirror 29. Thanks to the particular system of opening / closing of the case 1, the cover 5 can easily include a mirror 29 on its internal face.

De façon avantageuse, les différentes pièces sont en matériaux thermoplastiques, par exemple en polypropylène (PP), en polyéthylène (PE), en poly-oxo-méthylène (POM), en poly-butylène téréphtalate (PBT), en acrylonitrile butadiène styrène (ABS), en styrène acrylonitrile (SAN), en styrène acrylonitrile/acrylonitrile butadiène styrène (SAN/ABS) ou en polycarbonate/acrylonitrile butadiène styrène (PC/ABS), de préférence en ABS, en SAN/ABS ou en PC/ABS qui sont des matériaux ayant un fini plus esthétique.Advantageously, the different parts are made of thermoplastic materials, for example polypropylene (PP), polyethylene (PE), poly-oxo-methylene (POM), poly-butylene terephthalate (PBT), acrylonitrile butadiene styrene ( ABS), styrene acrylonitrile (SAN), styrene acrylonitrile / acrylonitrile butadiene styrene (SAN / ABS) or polycarbonate / acrylonitrile butadiene styrene (PC / ABS), preferably ABS, SAN / ABS or PC / ABS which are materials with a more aesthetic finish.

Pour obtenir des effets avantageux supplémentaires, les variantes et les modes de réalisation pourront être combinés sans sortir du cadre de l'invention.To obtain additional advantageous effects, the variants and embodiments may be combined without departing from the scope of the invention.

Dans le boîtier 1 cosmétique selon l'invention, un joint d'étanchéité 21 est disposé sur la base ou le couvercle et assure une étanchéité du boîtier. L'étanchéité est améliorée par la présence d'un verrouillage multipoints. Ainsi, les moyens de verrouillage 13 sont répartis sur le pourtour du boîtier 1 et assure une pression suffisante sur le joint d'étanchéité 21 pour maintenir une étanchéité non seulement aux impuretés mais également aux fluides, tels que des liquides, entre l'intérieur et l'extérieur du boîtier.In the cosmetic case 1 according to the invention, a seal 21 is arranged on the base or the cover and ensures that the case is leaktight. The tightness is improved by the presence of a multi-point locking. Thus, the locking means 13 are distributed around the periphery of the housing 1 and ensures sufficient pressure on the seal 21 to maintain a seal not only against impurities but also against fluids, such as liquids, between the interior and the outside of the case.

De plus, le boîtier 1 comprend une pièce additionnelle 11 qui peut être mise en mouvement par rapport au couvercle 5. Cela permet le passage de la position fermée à la position ouverte du boîtier 1 en appliquant une force plus importante, on peut ainsi disposer un joint d'étanchéité 21 entre le couvercle 5 et la base 3 sans qu'il complique l'ouverture ou la fermeture.
De plus la pièce additionnelle 11 permet d'éviter d'éventuels frottement entre le joint d'étanchéité 21 et le couvercle 5 et notamment une usure prématurée du joint et une détérioration de l'étanchéité du boîtier 1.In addition, the housing 1 comprises an additional part 11 which can be set in motion relative to the cover 5. This allows the passage from the closed position to the open position of the housing 1 by applying a greater force, it is thus possible to have a seal 21 between the cover 5 and the base 3 without complicating the opening or closing.
In addition, the additional part 11 makes it possible to avoid possible friction between the seal 21 and the cover 5 and in particular premature wear of the seal and deterioration of the seal of the housing 1.

Par ailleurs, le verrouillage classique, notamment par bouton poussoir, est remplacé par un décalage de l'effort à exercer. L'utilisateur active le verrouillage manuellement et on peut ainsi s'affranchir du système bouton poussoir.Moreover, the conventional locking, in particular by push button, is replaced by an offset of the force to be exerted. The user activates the locking manually and it is thus possible to dispense with the push-button system.

Plus de liberté dans le design du boîtier est possible. On peut ainsi envisager un boîtier 1 cosmétique très fin, avec un design très épuré, sans élément de verrouillage/déverrouillage apparent.More freedom in the design of the case is possible. It is thus possible to envisage a very thin cosmetic case 1, with a very refined design, without visible locking / unlocking element.

On peut également prévoir d'intégrer des éléments supplémentaires au niveau du couvercle 5, tel qu'un miroir, étant donné que l'ouverture est déclenchée par la mise en mouvement d'une pièce additionnelle 11 enveloppant le couvercle 5 et que le couvercle 5 n'est pas encombré d'un éventuel bouton poussoir.It is also possible to provide for the integration of additional elements at the level of the cover 5, such as a mirror, given that the opening is triggered by the setting in motion of an additional part 11 enveloping the cover 5 and that the cover 5 is not encumbered with a possible push button.
