Description

CASING HAVING A HINGED LID

The subject of the present invention is a casing, in particular for containing a cosmetic product and/or device, in particular an applicator.

Such a casing generally has a locking means for keeping a lid in what is referred to as a "closed" position on a base.

The casing may have return means to make it easier for the lid to move from the closed position to an open position. The return means, which are under load in the closed position, automatically drive the lid into the open position when the locking means is unlocked.

In order to drive the lid into the open position, it is necessary for the return force to be sufficiently strong. This force is defined depending on the mass of the driven lid.

In particular, in the case of casings for cosmetic use that are held in the user's hand, the weight of the lid depends on the position in which the user holds the casing and on the way in which gravitational force opposes the return force. In order to make it possible for the lid to open automatically regardless of the position in which the user holds the casing, the return means that are used are generally highly loaded and designed to generate a return force greater than the maximum weight of the lid.

This is liable to cause the lid to move too abruptly from the closed position to the open position under certain circumstances. Casings that open more slowly have thus been proposed.

In particular the application FR 2 669 370 and the international application W02006/01 1355 disclose introducing a viscoelastic brake into the hinge so that the lid opens gradually.

The application FR 2 684 962 describes a casing that opens in a controlled manner, having a torsional elastic element mounted between the base and the lid with a torsional preload in the closed position, so as to exert on the lid a pivoting torque about the hinge, causing complete, slow and gradual opening after unlocking.

The application EP 1 464 558 describes a hinge having a rotation damping means in the form of a cartridge mounted between the lid and the base. The damper has in particular a rubbing means disposed between two parts of the cartridge that are able to rotate, Other casings having a retarder are described in the application US2003/173369 and in the Japanese applications JP2005/261729 and JP2008/10762.

The prior art devices generally use bulky hinges that have retarders that are complex to manufacture and to assemble, thereby resulting in relatively expensive devices that are sometimes insufficiently reliable in operation.

There is thus a need for mechanisms for assisting in the opening of casings, which are relatively inexpensive and easy to manufacture.

Moreover, the known retarders are not ordinarily suitable for casings having a cylindrical overall shape.

Consequently, there is interest in providing retarders that are suitable for casings of various shapes.

The invention aims to meet all or some of these needs, and achieves this aim, according to a first aspect, by virtue of a casing having a lid hinged to a base and a mechanism for assisting in the opening of the lid, having an elastic return member that urges the lid into an open position and a brake that moves along at least one friction surface in order to generate a braking force that slows the opening movement of the lid relative to the base.

The opening speed depends on the coefficient of friction of the brake and on the return force of the elastic return member.

The invention can be implemented, if desired, with a smaller number of parts, thereby making it possible to reduce the manufacturing costs of the casing.

The invention does not use hydrodynamic friction and does not require the presence of a viscous fluid with the associated sealing constraints.

According to embodiments of the invention, the elastic return member works in compression or in tension.

The brake can be designed to move substantially in translation along the friction surface when the lid pivots under the action of the elastic return member bringing the casing into the open position. The casing is preferably designed to be closed again by simply pressing on the lid. While the casing is being closed, the brake moves along the friction surface in the opposite direction.

The friction of the brake on the friction surface does not take place in a shock absorber. A hinge can connect the lid to the base, so as to allow the lid to pivot about a geometric axis of rotation.

The hinge has for example a first part that is fixed relative to the lid and a second part that is fixed relative to the base. The first and second parts are for example parts in one piece with the lid and with a part of the base, respectively, being produced in particular by moulding, simplifying the manufacture of the hinge compared with the known opening systems having retarders, which generally have a complex hinge.

The casing may have a means for locking in the closed position, for example by snap-fastening. Such systems are known to those skilled in the art.

The brake has for example a pad designed to be in contact with the friction surface. The geometry of the pad and its composition are chosen to generate predefined friction during the movement of the brake. The pad is preferably made of an elastomeric material, in. particular selected from among silicones, nitriies, butyls, natural or synthetic latices, EPDMs, polyurethanes, blends of polypropylene and SBS. SEBS, or EPDM, natural, synthetic or thermoplastic elastomers, in particular copolymers of polypropylene and of SEBS, styrene-butadiene or ethylene-vinyl acetate copolymers, very low density polyethylenes, nitrile rubbers, polychloroprene or neoprene, ethylene propylene diene terpolymers (EPDMs), butadiene-acrylonitnle copolymers, polyurethanes, piasticized polyvinyl chlorides, and crosslinked rubbers, in particular those based on silicone.

The brake is preferably fixed to the elastic return member. It may be fixed directly to the elastic return member or, in one variant, to a holder having a housing for receiving the brake. The latter is for example force-fitted in the holder.

The holder has for example a means for fixing the elastic return member, for example a hook.

The holder may have two parts, made for example of thermoplastic material, that are fixed together in a removable manner. These two parts may be inseparable from one another, thereby forming a one-piece unit. They may be connected together by a hinge connection, for example a film hinge. The two parts preferably have an opening for at least a part of the pad to pass through.

The holder may be made of metal, or plastics material, in particular selected from among the polyolefms. The casing may have a flexible tether connecting the brake to the base of the casing, in particular in the region of the hinge. The flexible tether may be fixed to the brake or to the holder, the latter being made for example in one piece with the flexible tether, in particular by moulding.

The flexible tether may be in the form of a strip or a wire.

The flexible tether may be made of metal, or plastics material, in particular selected from among the polyolefins. PA, and TPE.

In one exemplary embodiment, the base has a hoop and/or a hoop insert. The flexible tether is then for example fixed to the hoop and/or to the hoop insert, and in particular retained by clamping between the hoop and the hoop insert.

The casing may have a body with is encircled by the hoop. This body may have an opening.

The flexible tether has for example fixing means that are configured to cooperate with fixing means of the hoop or of the body.

The flexible tether may be designed to directly connect the brake to the body of the casing.

The flexible tether may form all or part of the elastic return member, being for example in the form of a wire spring or leaf spring made of elastically deformable material.

The elastic return member may surround the flexible tether at least in part. The elastic return member has for example a coil spring, in particular having a flattened section, wound around a part of the flexible tether. Said coil spring is for example secured to the flexible tether and/or to the brake by being mounted on, in particular threaded onto, a guide formed on the holder.

At least in the closed position of the casing, the flexible tether may be diverted by a deflection element of the casing, preferably belonging to the base, in particular to the abovementioned hoop or hoop insert.

The movement of the brake in translation along the friction surface may be obtained by virtue of the difference in length undergone by the flexible tether during the opening/closing movements of the lid, on account of the presence of the deflection element. The deflection element may be rounded at least in part. It may be fixed to the lid or to the base. It has for example a groove for guiding the flexible tether, the latter sliding, stretching and/or unwinding, etc., therein.

The deflection element is defined for example by a portion of the hinge, in particular a cylindrical portion of the hinge, in particular by the second part of the hinge, which is fixed relative to the base.

In a variant, the deflection element may belong to the lid, being in particular defined by the first part of the hinge, which is fixed relative to the lid.

The brake moves along the friction surface between a first position and a second position when the lid pivots under the action of the elastic return member, starting from the closed position of the casing.

The distance by which the brake moves between the first position and the second position is for example between 1 and 20 mm, better still between 5 and 10 mm.

The opening of the lid may be limited by the respective positions of the lid, of the base, in particular of the hoop, and of the hinge in the open position. Advantageously, the mechanism for assisting in opening is configured to allow maximum opening taking into account the relative movement of the lid and the base.

The maximum opening angle of the casing is advantageously greater than 90°, for example between 120° and 180°.

For a cosmetic casing, an angle of greater than 90°, or even more, makes it easier to access the product and makes it possible to use a mirror fixed to the inside of the lid.

The mechanism for assisting in the opening of the lid may have a means for limiting the movement of the brake and also the opening angle of the lid, for example a relief on the friction surface, against which the brake or the holder comes into contact when the brake is in the second position.

The lid may have a cover and an insert joined to the cover. The cover may define an external surface of the lid when the casing is closed.

The brake may move in a space, of variable or constant height h, situated betwee the insert and the cover.

A portion of the flexible tether defined above may move in translation in this space. The brake may rub against a surface of the insert and/or of the cover, defining the friction surface at least in part.

In one exemplary embodiment, the friction surface is defined at least in part by a face of the cover or of the insert. If need be, the brake may rub both against the insert and against the cover during its movement.

The abovementioned insert may be limited laterally by two walls, produced in particular by being moulded with or joined to the insert, forming the friction surface at least in part. The distance between the walls defines the width of the space; this may be constant, the walls then being parallel.

In one variant, the width of the space is variable.

The height and/or width of the space can be chosen so as to alter the rubbing force against the brake.

The height and/or width of the space can vary along the friction surface so as to generate a variable rubbing force depending on the degree of opening of the lid. Advantageously, the geometry of the space can thus help to control the speed. The height and/or width are for example smaller at the start of opening. The brake is thus more compressed, resulting in very slowed opening. When the opening angle has reached and exceeded 90°, the height and/or width can be greater, generating less significant braking.

In order to create a relative movement between the brake and the friction surface, the brake may move on the fixed surface or vice versa.

The friction surface may have a surface state defined by the presence of reliefs and/or of a coating that has a suitable coefficient of friction, this surface state being able to vary along the friction surface so as to generate variable friction along the latter, depending on the degree of braking desired.

The brake may be connected to an attachment point of the casing, in particular away from the hinge, with the aid of the elastic return member.

In order to ensure sealed closure, the casing, in particular the lid and/or the base, may have a seal, for example an annular seal The latter may be hollow or solid and have any desired, open or closed, cross section, for example circular or in the form of an Ω.

The seal is preferably made of elastomeric material, in particular thermoplastic material. The seal may be silicone-based. The elastic return member and/or the brake may form one piece with the seal, for example being produced with said seal by moulding or overmoulding material, preferably thermoplastic elastomeric material.

The material of the seal is selected, for example, from among silicones, nitriles, natural or synthetic latices, EPDMs, polyurethanes, blends of polypropylene and SBS, SEBS, or EPDM, natural, synthetic or thermoplastic elastomers, in particular copolymers of polypropylene and of SEBS, styrene-butadiene or ethylene-vinyl acetate copolymers, very low density polyethylenes, nitrile rubbers, polychloroprene or neoprene, ethylene propylene diene terpolymers (EPDMs), butadiene-acrylonitrile copolymers, polyurethanes, plasticized polyvinyl chlorides, and crosslinked rubbers, in particular those based on silicone.

The invention thus advantageously makes joint use of the sealing and elasticity properties of the elastomeric material.

The seal may be fixed to the lid or to the base by any means known to those skilled in the art. It is for example forcibly fixed, snap-fastened, adhesively bonded or welded. It is preferably fixed to the insert.

The casing may have a means for locking the closed position. The locking means has for example a push button that serves to release the lid.

The lid and/or the base may be made, at least in part, of one or more material(s) selected from among glass, wood, metals, ceramics, elastomers and thermoplastic materials, in particular rigid ones, this list being non-limiting. In particular, the lid, notably the insert, and/or the base, in particular the hoop and the hoop insert, may be made of ABS at least in part.

The deflection element of the casing may belong to the base or to the lid.

The casing may have a mirror.

The casing according to the invention may have a flattened overall shape, with a contour that is generally circular or non-circular in flattened-out top view, polygonal or non-polygonal, or oval, and be perforated or non-perforated.

The casing may have a housing for receiving a cosmetic applicator, in particular for application to the skin or lips, for example in the form of a powder puff.

The base may have a housing intended to accommodate a cosmetic composition. The casing may thus contain a makeup or care composition such as one or more eyeshadows, face powders, foundations, compact or other powders, or creams. These compositions may be contained in one or more dishes that are removable or non-removable relative to the casing.

In one variant, the body of the casing constitutes a container, in particular for containing a cosmetic composition.

The lid, the hoop and the mechanism may together form a closure assembly that is manufactured separately and be joined to different containers, thereby facilitating large-scale production of casings which have different capacities but have the same closure assembly.

The hoop of the cap has for example fixing means that are designed to cooperate with a neck of the container. The assembly may be snap-fastened, screw- fastened or fixed by any other means known to those skilled in the art to the neck of the container.

According to another aspect, the subject of the invention is an assembly having a lid hinged to a hoop and a mechanism for assisting in the opening of the lid, configured to be fixed to the neck of a container and to form a casing as defined above.

The invention may be better understood from reading the following detailed description of non-limiting illustrative embodiments thereof and from examining the appended drawing, in which:

Figures 1A and IB illustrate, in partial section, a closure assembly with which the casing from Figure 1 is equipped, in open and closed positions, respectively,

Figures 2A - B and 3A - B illustrate, in partial section, different exemplar embodiments of the casing according to the invention in open and closed positions,

Figure 4 shows a detail of one exemplary embodiment of the casing according to the invention,

Figure 5 is a schematic and partial exploded view of a variant of the mechanism for assisting in opening prior to joining to the brake,

Figure 6A illustrates the lid 2 of the casing from Figure 1 in partial cross section, Figure 6B shows a side view of a detail of the lid of the casing from Figure

1, and

Figure 6C is a cross-sectional view on Vic- Vic in Figure 6B.

Figure 1 shows a casing 9 in the form of a pot comprising a base 1 and a lid 2. A mechanism 3 for assisting in opening urges the lid 2 into the open position.

The casing has a hinge 4 which connects the lid 2 to the base 1 in a pivotable manner.

In the closed position, the lid 2 covers an opening 15 in a body of the base 1.

Said body forms a container 16 provided with a neck 17 and has a housing 19 intended to contain a composition P. In one variant, the housing 19 holds a refill of composition, the casing then being reusable.

The hinge 4 is fixed to the body 10 for example by a hoop 39. The latter encircles the neck 17, to which it is fixed for example by snap-fastening. In one variant

(not illustrated), the hoop is screwed onto the neck. The invention is not limited to one particular fixing method.

In a preferred variant, the iid 2, the abovementioned mechanism 3 and the hoop

39 form at least one assembly that is designed to close the container Ϊ6. The lid 2 has a relief 29 designed to cooperate with locking means 79 on the base 1, for example on the hoop 3 encircling the neck 17, as illustrated.

A push button 7 makes it possible to unlock the iid. it is advantageously situated on the base 1 , thereby making it possible to easily hold and open the casing with one hand.

The lid 2 has a cover 20 and an insert 25 to which a mirror 22 can be fixed, as illustrated.

In the example in question, the lid 2 also has a seal 50 that seals the casing when the lid 2 is in the closed position.

The hinge 4 has a first part 41 that is fixed relative to the lid 2 and a second part 43 that is fixed relative to the base 1. In the example illustrated, these first and second parts belong to the cover 20 and to the hoop 39, respectively.

Figures 1A and IB show the closing assembly 90 from Figure Ϊ, in closed and open positions, respectively, in section on I-I in Figure 6A, the insert 25 and the mechanism 3 for assisting in opening remaining visible. Said mechanism 3 has a brake 30, which is connected to the base 1 , in the region of the second part 43 of the hinge 4, by a flexible tether 6. The flexible tether is for example held by clamping, at least in part, between the hoop 39 and a hoop insert 37.

The brake 30 is fixed to the flexible tether 6. in the example in question, it is housed in a holder 36 that is moulded in one piece with the flexible tether 6, as illustrated in Figures 6B and 6C.

The brake 30 is made for example of elastomeric material, in particular silicone, and has a number of pads 35.

The insert 25 has two opposing walls 240 that form between one another a space 33 in which the brake 30 moves, and define friction surfaces 34 in contact with which the pads 35 move.

The brake 30 is designed to move in translation along these friction surfaces 34, between a first position illustrated in Figure 1 A, corresponding to the closed position of the casing 9, and a second position shown in Figure IB, when the casing 90 is open. The opening of the lid is limited by the relative movement of the cover 20 and the hoop 39, as illustrated in Figure IB.

In the example illustrated, the walls 240 are parallel, the width L of the space 33 being constant. In one variant (not illustrated), the width L varies and increases for example when the brake moves between the first and the second position.

The brake is fixed to an elastic return member 5. The latter is in the form of a coil spring having a flattened section in the example illustrated. It is mounted on a guide 360 formed by a part of the holder 36 and encloses a portion of the flexible tether 6.

In the closed position, the return member 5 is compressed in the space 33 between the brake 30 in the first position and a wall 260 having an opening 265 for the flexible tether 6 to pass through. The latter is in part wound around a deflection element 65. The latter is defined for example by a portion of the hinge 4, in particular a cylindrical portion thereof, in particular formed with the second part 43.

The deflection element 65 advantageously has a groove 64 that serves to guide the flexible tether 6.

During the opening of the casing 9, the brake 30, carrying along the flexible tether 6, moves in translation under the action of the elastic return member 5, which creates an opening torque. In the example illustrated, the maximum movement δ of the brake 30 is between 6 and 7 mm.

Figure 6 A illustrates the lid 2 from Figure 1 in partial cross section on VI- VI, before the brake 30 and its holder 35 are fitted in the space 33.

Figure 6B shows a side view of the brake 30 in the holder 36 before the elastic return member 5 is mounted on the guide 360 so as to surround the flexible tether 6.

On each side, the brake has two pads 35 for rubbing against each of the friction surfaces 34. The geometry of the part of the pads 35 that is in contact with the friction surfaces is chosen so as to obtain the desired friction depending on the material used for the pads. These are made for example of silicone. In one variant, the brake has a unilateral pad.

Another example of the mechanism 3 for assisting in opening is shown partially in Figure 2A in cross section in the region of the hinge 4. In this figure, the lid 2 is kept in the closed position by locking means (not illustrated).

The brake 30 is in the form of a silicone pad 35, for example. It is fixed to an elastic return member 5 in the form of a leaf spring, for example. In the closed position of the casing, the return member 5 is compressed and deformed.

The friction surface 34 is formed, in this example, by the opposing faces of the cover and the insert 25.

The return member 5 forms a flexible tether 6 connecting the brake 30 to the base 1. In the closed position of the lid 2, as illustrated, the flexible tether 6 is, as in the above-described example, wound in part around a deflection element 65. formed by a portion 43 of the hinge.

The flexible tether 6 is for example fixed, as illustrated, to the base 1 by being clamped between the hoop 39 and the body 10 of the casing.

When the lid 2 starts, as shown in Figure 2B, to open automatically by pivoting about the axis X of the hinge 4 in the direction of the arrow o under the action of the return force of the elastic return member 5, the flexible tether 6 straightens, causing the brake 30 to move along the arrow T in the space 33 delimited between the cover 20 of the lid 2 and the insert 25. The rotational movement of the lid simultaneously causes a movement of the brake 30 in translation along the friction surfaces 34 delimiting the space 33. The brake 30, the elastic return member 5 and the space 33, in particular the height h thereof, are chosen in an appropriate manner for the friction of the brake 30 to regulate the speed of opening of the lid 2 in the desired manner.

Figures 3 A and 3B show another example of a mechanism 3 for assisting in the opening of the lid 2.

In this example, the mechanism 3 has a return member 5 in the form of a coil spring. Said spring is fixed by a hook 55 to a holder 36 in which the brake 30 is situated. The latter is thus connected by the return, member to an attachment point 32 of the lid 2 on the opposite side from the hinge 4 and by a flexible tether 6 to a fixing point 31 on the base 1.

The return member 5 in the preceding examples works in compression.

In the variant in Figures 3A and 3B, in the closed position of the lid illustrated in Figure 3 A, tlie return member 5 works in tension and subjects the brake 30 to a force F while the flexible tether 6 keeps the brake in a first position. During the opening of the lid 2, as illustrated in Figure 3B, under the action of the return member 5, the brake 30 moves in the direction of the arrow T inside the space 33 situated between the cover 20 and the insert 25, carrying along the flexible tether 6, which extends. The brake 30 is subjected to the joint action of the return member 5 and the rubbing forces along two friction surfaces 34_*

The assistance mechanism 3 of the casing 9 illustrated in Figure 4 has a return member 5 that acts in compression in the form of a leaf spring, forming a flexible tether 6. The leaf spring is for example forcibly inserted and/or adhesively bonded in a housing of the brake 30.

The flexible tether 6 connects the brake 30 to the base 1. The latter has a hoop 3 and a hoop insert 37, between which the flexible tether 6 is clamped.

In this example, the movement of the brake 30 is limited by a relief 38 on the friction surface 34. The use of a leaf spring limits the opening angle a of the lid 2 and the presence of the relief 38 makes it possible to keep the brake 30 along the friction surface 34 formed by an internal face of the lid 2.

In the variant in Figure 5, the return member 5 and the brake 30 of the mechanism 3 for assisting in opening are made in one piece with the seal 50 by moulding a thermoplastic or non-thermoplastic elastomer ic material, for example an elastic material of the butyl or nitrile type, this list not being limiting. The elastic return member 5 thus formed works in tension. It has for example the appearance of a preformed tab so as to adapt more easily to the shape of th e casing 9.

The mechanism 3 has a flexible tether 6 with a portion 640 having a shape chosen to be wound around a deflection element 65 of the casing.

The flexible tether 6 has first fixing means 61 in order to be connected to a fixing part 31 of the casing 9, in particular between the hoop 39 and a hoop insert 37, as described above.

The brake 30 has two pads 35. It is designed to be fixed to the flexible tether 6 by a holder 36. In the example in question, the holder 36 is formed of two parts 62 that are made in one piece by moulding PP (polypropylene) and hinged by way of a film hinge 66. The holder 36 has lateral openings 63 for the pads 35 to pass through, and also first fixing means 67 designed to cooperate with second fixing means 68 on the flexible tether 6.

The seal 50, which is for example hollow, is configured to be fixed to the insert

25.

The joint 51 between the seal 50 and the return member 5 is thus designed to form an attachment point 32 which is fixed relative to the lid 2.

The invention is not limited to one particular shape of the casing.

In one variant, the brake and the flexible tether move in a space formed within the base.

The hoop and/or the hoop insert can be configured to form parts of the base that are situated in particular around the opening. In one variant, the hoop and/or the hoop insert form parts of the base.

The expression "having a" should be understood as being synonymous with "having at least one".
