As illustrated, the invention relates to a housing 10, 10 'especially for a cosmetic product, comprising a base 20, 20' and a lid 30, 30 'articulated with respect to each other. Said base 20, 20 'and said lid 30, 30' are advantageously articulated, in rotation, around a hinge 12, 12 '. The hinge axis X, X 'around which said rotation occurs is here located in the vicinity of the periphery of said housing 10, 10'; said axis X, X 'is visible in Figures 1 and 3. Said housing 10, 10' further comprises locking means for maintaining in said closed position said cover 30, 30 'on said base 20, 20'. According to the invention, said locking means 42, 42 'are articulated with respect to the base 20, 20', here around a hinge axis Y, Y ', so as to be retracted inside said base 20, 20 'by opening said lid 30, 30'. Said axis Y, Y 'is visible in FIGS. 1, 6, 7 and 10. This hinge axis Y, Y' is parallel to the axis of articulation X, X 'around which rotation of the lid 30 is allowed. , 30 'with respect to the base 20, 20'. The locking means 42, 42 'are located opposite said axis of articulation X, X', and with respect to said hinge axis Y, Y '. It is also possible that said locking means 42, 42 'are located on lateral sides of the housing, for example to cooperate with side edges of the cover.

The locking means are, for example, in the form of at least one hook 42, 42 'adapted to cooperate with at least one counter-form 32, 32' located inside said cover 30, 30 '. Said locking means may also be in the form of two hooks 42, 42 'able to cooperate with two counter-forms 32, 32' located inside said cover.

The shape given to the hook 42, 42 'as well as against the form 32, 32' in the figures is not limiting. It is indeed conceivable to provide any other form of hook 42, 42 'which fulfills the function of holding said lid 30, 30' on said base 20, 20 'in the closed position.

On the other hand, the housing 10, 10 'comprises a kinematic assembly provided with an intermediate piece 40, 40. The hook or hooks 42, 42' belong to this intermediate piece 40, 40 '.

The remainder of this description will attempt to explain how the cover 30, 30 'acts on the intermediate piece 40, 40' in order to control the retraction of the hook or hooks 42, 42 'in the base 20, 20'. when opening said lid 30, 30 '.

In FIGS. 1 and 2, the cover acts directly on the intermediate piece 40 which carries the hinge pin Y, here located halfway between the hinge 12 and the locking means 32, 42. It is also possible to position any between the hinge 12 and the locking means 32, 42 for said hinge axis Y.

The lid 30 has two parts, a first part 31 called hinge part, and a second part 33 called reinforcement of the lid. The hinge portion 31 is derived from the frame 33 of the lid and cooperates with the hinge 12 around which said base 20 and said lid 30 are articulated in rotation. Said articulating portion 31 has an outgrowth 34, preferably integral with said cover 30, more particularly with said frame 33. This protrusion 34 makes it possible to tilt the intermediate piece 40 around the hinge axis Y. effect the protrusion 34 abuts on the end 41 of the intermediate piece 40 which is in its vicinity; this leads to the tilting of the intermediate part 40 relative to the hinge axis Y. As a reminder, the hook or hooks 42 are located opposite said end 41 and with respect to said hinge axis Y.

Thus, as can be seen in FIG. 2, once the lid 30 is closed, the protrusion 34 keeps the intermediate piece 40 tilted and the hook or hooks 42 in the high position. The or said hooks 42 held in the upper position cooperate with the counterforms 32 here made in the frame 33 of said cover 30 to maintain said lid 30 in a closed position on said base 20. The protrusion 34 serves as a mechanical means adapted to transform the opening and closing of said lid 30 into a tilting of the intermediate piece 40; said intermediate piece 40 is then a rocker.

Said intermediate piece 40 has, for example, an annular shape corresponding to the periphery of the base 20. Said housing 10 may further comprise a receptacle, possibly compartmentalized, for receiving the product or products contained in the housing 10. Ledit receptacle is located in said base 20.

Said intermediate piece 40 is located between said receptacle and said base 20. Figures 3 to 11 illustrate a second embodiment of the invention. This embodiment has a housing 10 'which comprises a plate 50' sliding relative to the base 20 '. The plate 50 'is configured to move relative to the base 20' when rotating the lid 30 '. The plate 50 'comprises a first end 51' connected to the lid 30 ', in particular to the hinge portion 31' of said lid 30 '. The cover 30 'here indeed has two parts, a first part 31' called the hinge part, and a second part 33 'called the frame of the lid 30'. As in the previous mode, the hinge portion 31 'may be derived from the frame 33' and cooperate with the hinge 12 'around which said base 20' and said cover 30 'are articulated in rotation.

As best seen in Figure 4 said hinge portion 31 'comprises an arm 34' integral with said frame 33 '. This arm 34 'follows the movement of the lid 30'. It is articulated in rotation with the plate 50 'and it is precisely this arm 34' which actuates the sliding.

On the other hand, the plate 50 'is provided with cams 53' at the opposite end 52 '. These cams 53 ', particularly visible in Figures 6, 8, 10 and 11, slide inside guide rails 60' embedded in the base 20 '. Said cams 53 'are lateral protuberances, preferably integrally formed with the plate 50'. Said material will preferably belong to the family of plastics, it may be acrylonitrile butadiene styrene (ABS) for example. The exploded view of Figure 6 is useful for illustrating this second embodiment. It is visible, inter alia, that the lid 30 'may comprise a piece 36' forming said armature. The counterform or 32 'will be practiced in this room 36'. On the other hand, this piece 36 'has two opposite faces, one allowing the attachment of an accessory, such as a mirror 37', and the other, an outer cover of the cover. It is also visible in FIG. 6 that the plate 50 'may comprise a receptacle 54', possibly compartmentalized, for receiving at least a portion of the products contained in the housing 10 '. The base 20 'will comprise, in this embodiment, an internal trim skirt 62' housed therein. On the other hand, the intermediate piece 40 'will here be located between said covering skirt 62' and said base 20 '. The intermediate piece 40 'will have, for example, an annular shape, as in the first embodiment. This annular shape corresponds to the periphery of the base 20 'and goes around said covering skirt 62'. Said intermediate piece 40 'will further have an articulated portion 45' about the hinge axis Y '; said articulated portion 45 'comprising said hooks 42'. Only the articulated portion 45 'of said intermediate piece 40' will be able to pivot inside said base 20 ', the remaining part of said intermediate piece 40' having no degree of freedom with said base 20 '. It is interesting to note that the embedding of the remaining portion in the base 20 'is not necessarily permanent. The dressing skirt 62 'visible in this exploded view conceals from the user said intermediate piece 40'. It should be noted that one or more lights 64 'are formed on the surface of said dressing skirt to allow the passage or hooks 42'. The dressing skirt 62 'may form in its center a receptacle. This receptacle may receive a portion of the products contained in the housing 10 ', for example a sponge 63'. It is also visible in Figure 6, slides 61 'which will be fixed inside the base 20'. Said slides present here said guide rails 60 'within which said cams 53' will slide. The use of slides 61 'makes it possible to improve the sliding of the cams 53' in the rails 60 'by better management of the games and a reduction of the parasitic noises. These slides will preferably be made of a plastic material, for example based on polyoxymethylene (POM).

Figures 7 to 9 illustrate the sliding of these cams 53 'inside said guide rails 60'. Figures 3 and 7 both show the housing 10 'in the open position. In this position, the hooks 42 'are in the low position. The tray is in a position to have access to the receptacle formed by the skirt 62 '. As can be seen in FIG. 10, the cams 53 'do not then interfere with the articulated part 45' of the intermediate piece 40 ', which is provided at rest in the low position.

Figures 4 and 8 illustrate the housing 10 'when the lid 30' is in an intermediate position, neither open nor closed. The arm 34 'belonging to the hinge portion 31' of the cover 30 'causes the displacement of the plate 50' with which it is articulated. It slides in the guide rails 60 'with the cams 53' located at the end 52 'opposite that by which said plate 50' is driven.

The objective is to accommodate the tray 50 'in the base 20', above the receptacle formed by the skirt 62 ', while bringing or hooks 42' in the high position. As illustrated in FIG. 11, this objective is achieved when the cams 53 ', interfering with the articulated part 45' of the intermediate piece 40 ', cause the elevation of said articulated portion to position the hook or hooks 42 'in the up position. Indeed, said intermediate piece 40 'is articulated relative to the base 20' around the axis Y 'visible in Figure 10. This elevation can be done by elastic deformation of the articulated portion 45' of said intermediate part 40 ' .

Figures 5 and 9 illustrate the housing 10 'when the lid 30' is in the closed position. The cams 53 'then came to a stop in the guide rails 60'. It is noted here that the portion 45 'provided with the hooks 42' pivots relative to said base 20 'while the portion of said intermediate piece 40', opposite that provided with the hooks 42 'relative to the Y 'axis, remains stationary since it is embedded in said base 12'. When the hook or hooks 42 'are in the high position, the lid 30' is in the closed position and the said hook or hooks 42 'cooperate with the counterform or forms provided in the armature 33' of the lid 30 'in order to maintain said lid 30 'in the closed position on said base 20'. The invention is not limited to the embodiments that have just been described. Although not shown in the figures, the elevation of the hook or hooks 42, 42 'is preferably initiated when the angle between the cover 30, 30' and the base 20, 20 'exceeds 30 degrees in approaching 0 degree. In addition, the hook or hooks retract when the angle between the lid 30, 30 'and the base 20, 20' exceeds 30 degrees by approaching 180 degrees. It will be understood that in the first embodiment, the retraction of the hooks 42, 42 'in the base 20, 20' is ensured by gravity effect. This retraction can also be forced by a return spring type spring; said spring being able to be located, for example, between the base 20, 20 'and the intermediate piece 40, 40'. However, such features may also be used, inter alia, with the second embodiment.

It should be noted that alternative embodiments are of course possible. In particular, it is also conceivable, in a third, a fourth and a fifth embodiment, that the hook can be retracted into the base 20 of the housing 10 otherwise than previously described.

Figure 12 illustrates the retraction of a hook 42 'in translation, rather than tilting. This representation is schematic. FIG. 13 illustrates a fourth embodiment in which the retraction of the hook 42 "is provided from the front face of the base 20. The hook 42" is no longer retracted into the base 20 "by a movement of the top downwards, but by a lateral movement.Therefore, the cover 30 "has a return 35" in which is engaged the hook 42 "to maintain the housing 10" closed.

A fifth embodiment is still possible. Said fifth embodiment is illustrated in Figures 14 and 15. In the three embodiments described above, the hook 42, 42 ', 42 "is retracted into the base 20, 20', 20" by a movement from the top to the down, or even by a lateral movement.

In this fifth embodiment, the hook 42 "'is retracted by rotation about a Z axis, said axis is visible in Figures 14 and 15. It is quite possible to combine the embodiments presented above. to optimize the expected result.

It is also possible to provide that the locking means are articulated relative to the cover. The latter is then configured so that said locking means are retracted into said cover when it is opened.
