[0046] In the rest of the description, reference will be made to an orthonormal basis X, Y, Z, where Z corresponds to an elevation axis representing the vertical direction, in which there can be seen: [0047] a longitudinal axis X, which is horizontal and extends from left to right in the top views; [0048] a transverse axis Y, which is horizontal and perpendicular to the longitudinal axis X and extends from front to rear in the top views; and [0049] a vertical axis Z, which is orthogonal to the longitudinal axis X and transverse axis Y and extends from top to bottom in the side views.

[0050] The expressions upper and lower refer to the upper part and the lower part of the figures, in the initial moulding position.

[0051] A device 10 for packaging a product is illustrated in FIGS. 1 to 10.

[0052] A product means a cosmetic product such as, for example, a finely ground, compacted solid product, in the form of compact powder, which is intended to be applied, for example, to the user's epidermis. The compact powder may be of the foundation, face powder or eyeshadow type that is picked up, for example, directly with the finger or with a powder puff or with a brush.

[0053] However, the invention is not limited to a cosmetic product. Other types of products, such as anhydrous paint, for example, could also be provided.

[0054] The device 10 is of the make-up case type and comprises a cover or lid 20 and a base or receptacle 30 connected to the lid 20 by an intermediate element or hinged platform 40.

[0055] The device 10 is a moulded one-piece component, as indicated in FIGS. 1 to 4 and 7.

[0056] The lid 20 is delimited by a front wall 21, a rear wall 22, which is opposite the front wall 21, two lateral walls 23, 24 and a lower surface 25 delimiting an inner cavity 26 for accommodating, for example, a mirror and/or an application element (not illustrated).

[0057] The front wall 21 comprises a protruding element 21a that extends beyond the lid 20 and that is designed to engage with a corresponding notch 31a provided on a front wall 31 of the base 30 in order to reversibly lock the lid 20 on the base 30.

[0058] The base 30 is delimited by a front wall 31, a rear wall 32, which is opposite the front wall 31, two lateral walls 33, 34 and a lower surface 35 delimiting an inner cavity 63 for accommodating the product.

[0059] The hinged platform 40 comprises a first hinge 41 connected to the lower part of the rear wall 32 of the base 30 and a second hinge 42 connected to the upper part of the rear wall 22 of the lid 20, which is opposite the lower surface 25.

[0060] In the initial moulding position, illustrated in FIGS. 1 to 4, the base 30 and the hinged platform 40 are situated in one and the same plane P1 and the lid 20 is situated in a plane P2 parallel to the plane P1.

[0061] The hinges 41 and 42 are of the film hinge type, in the form of a U-shaped transverse groove made in the upper surface 40a of the hinged platform 40. The hinges are also formed with a V-shaped transverse notch (not visible in the figures) made in the lower surface 40b of the hinged platform 40.

[0062] The first hinge 41 is designed to articulate the assembly formed by the lid 20 and the hinged platform 40 relative to the base 30 from an initial moulding position, visible in FIGS. 1 to 4, in which the lid 20 makes a first angle 1 of between 200 and 220 with the base 30, towards an open use position, visible in FIG. 5, in which the lid 20 makes a second angle 2 of between 70 and 100, for example equal to 90, with the base 30.

[0063] The second hinge 42 is designed to articulate the lid 20 relative to the base 30 from the open use position towards a closed position in which the lid 20 covers the base 30, as is visible in FIG. 6.

[0064] The hinges 41, 42 of the hinged platform 40 are situated in one and the same plane P1, and this makes it possible to simplify the mould, and to reduce the amount of moulding material necessary.

[0065] In the closed position, the front wall 21 of the lid 20 is aligned with the front wall 31 of the base 30 and the rear wall 22 of the lid 20 is aligned with the rear wall 32 of the base 30.

[0066] The rear wall 32 of the base 30 has a rounded cutout 37 so as to ensure that the lid 20 does not butt against the base 30 during the rotational movement of the lid 20 from the open position towards the closed position and vice versa. The rounded cutout 37 is illustrated in FIG. 6.

[0067] The rear wall 32 of the base 30 comprises a vertical cutout 32a provided with two vertical snap-fastening grooves 32b along the entire height of the rear wall 32. Each snap-fastening groove 32b has, in transverse cross section, a parallelepipedal or rounded shape designed to correspond to a corresponding shape on a snap-fastening element 44.

[0068] The hinged platform 40 comprises two vertical snap-fastening elements 44 that each protrude transversely from an opposite end of the upper surface 40a of the hinged platform 40 in the initial moulding position Each snap-fastening element 44 is intended to cooperate with a vertical groove 32b in the base 30.

[0069] In the open position, the snap-fastening elements 44 extend along the longitudinal axis X, as can be seen in FIGS. 7 and 8. In the closed position, the snap-fastening elements 44 extend along the vertical axis Z, as can be seen in FIG. 9.

[0070] Each of the snap-fastening elements 44 comprises a protuberance 44a, which protuberances extend beyond the upper surface 40a of the hinged platform 40 in two opposite directions along the transverse axis Y in the initial moulding position. Each protuberance 44a is intended to cooperate with a corresponding vertical groove 32b in the open position.

[0071] Therefore, the device only comprises a single snap-fastening line between the hinged platform 40 and the base 30. The snap-fastening line is realized by two attachment points formed by the cooperation between the vertical grooves 32b and the snap-fastening elements 44.

[0072] As illustrated in detail in FIG. 7, the hinged platform 40 comprises two members 45 for holding in position, each extending horizontally from a snap-fastening element 44 towards the centre of the hinged platform 40.

[0073] Each member 45 for holding in position cooperates, in the closed position, with a transverse projection 38 protruding from the bottom of the vertical cutout 32a in the base 30 towards the lid 20. In the closed position, the members 45 for holding in position come to bear vertically on the corresponding transverse projection 38, thus forming a bottom anti-translation stop.

[0074] As illustrated in detail in FIG. 7, the hinged platform 40 also comprises two anti-translation studs 46, each extending along the longitudinal axis in the initial moulding position.

[0075] Each anti-translation stud 46 cooperates, in the closed position, with a notch 39 of matching shape made in the bottom of the vertical cutout 32a in the base 30 between the two transverse projections 38. In the closed position, the anti-translation studs 46 come to be inserted in a corresponding notch 39, thus forming a top anti-translation stop.

[0076] The device 10 is manufactured from plastics material, such as for example polypropylene (PP), acrylonitrile-butadiene-styrene (ABS), PET, recycled PET or any material appropriate for a make-up case.

[0077] By virtue of the vertical cutouts 32a made directly in the base 30 and extending in a vertical direction, the snap-fastening force is significant and does not allow the user to easily move the lid 20 from the open position to the initial moulding position.

[0078] The combination of two anti-translation stops makes it possible to further increase the force required by the user to move the lid 20 from the open position to the initial moulding position. The holding of the hinged platform in the open position of the lid 20 is thus improved. The combination of two anti-translation stops also makes it possible to have a fixed position of the second hinge 42 in order for the lid to be correctly positioned flat on the base.

[0079] Furthermore, the mould used to mould the container 10 is of simple structure since the two snap-fastening elements 44 at the ends of the hinged platform 40 can be demoulded in the direction of opening of the mould. In general, all the elements can be demoulded in the direction of opening of the mould.

[0080] The container can thus be moulded in the same core without any additional slideway.
