Description

Technical field

[0001] This disclosure relates to a packaging device, and more particularly to a device for packaging a product, in particular a cosmetic product. Prior art

[0002] A packaging device, in particular for cosmetic products such as lipstick, cream, or spray, must be easy to carry, for example in a bag or purse, and must be used frequently. Thus, the packaging device must be light and compact, and allow easy extraction of the product it contains, i.e. requiring little effort and being able to be carried out simply, without the user having to pay particular attention to the maneuver he is performing. The device must also allow the product to be stored by a simple maneuver and not requiring any particular attention from the user. In addition, this storage must be reliable, i.e. an untimely exit of the product must be avoided.

[0003] International application WO 2014 / 096651, from the Applicant, proposes a solution using magnetic elements to hold the cosmetic product either in the dispensing position, or release position, or in the storage position, or retracted position. Although this solution is satisfactory, consumers now want packaging devices with a reduced ecological impact, for example without magnets. There is therefore a need for a new type of packaging device which, although not necessarily using magnets, has a level of reliability at least as good.

[0004] Application FR 2 999 891 A1 discloses the preamble of claim 1. Statement of the invention

[0005] For this purpose, the present disclosure relates to a device for packaging a product according to claim 1.

[0006] The support may carry the product or an intermediate container containing the product, such as a tank, whether or not equipped with a dispensing, spraying, etc. mechanism.

[0007] When the support is in the release position, it is subjected to the force exerted by the return system, which tends to maintain it in the release position. The force exerted by the return system can be overcome by a force exerted by the user, in order to return the support to the retracted position.

[0008] The retaining element retains the support in the retracted position. Neutralizing the retaining element means rendering the retaining element incapable of performing its function of retaining the support in the retracted position. When the retaining element is neutralized, the support is free to move between the retracted position and the disengaged position; then the restoring force intervenes which returns the support to the disengaged position. Resetting the retaining element is the opposite of its neutralization: after resetting, the retaining element is again capable of performing its function of retaining the support in the retracted position; however, the support itself may, at this time, no longer be in the retracted position. When the support returns to the retracted position, it will be retained again.

[0009] The restoring force may be an elastic restoring force, for example as exerted by an elastomer or a spring, or a magnetic restoring force, for example as exerted by a magnet. More generally, the restoring force may be exerted by a restoring system. The restoring force may be attractive or repulsive.

[0010] Due to the fact that the retaining element automatically resets in the absence of actuation of the actuator, typically when the actuator is released by the user after allowing the support to move into the release position, the support can very easily be retracted after dispensing the product, by a simple force countering the restoring force. The device is therefore of particularly simple construction and use, which makes it inexpensive and pleasant for the user.

[0011] Furthermore, the support is held in the retracted position by a retaining element, which can be reliably implemented and does not necessarily employ magnetic cooperation. If a magnet is nevertheless used as a return system, it may be relatively less powerful than in the prior art since the holding in the retracted position is ensured by the retaining element. As a result, the environmental impact of the packaging device is significantly improved.

[0012] In some embodiments, the support is longitudinally movable between the retracted position and the release position, and the actuator is capable of neutralizing at least one stop of the retaining element by moving said stop transversely. Thus, the stop of the retaining element, which opposes the return force in the retracted position, on the contrary allows the support to pass when it is neutralized, that is to say here moved transversely to the direction of movement of the support.

[0013] In some embodiments, the retaining element comprises a plurality of said stops, distributed circumferentially. The support is therefore more reliably retained in the retracted position. Although only one stop is described hereinafter, the properties disclosed may apply to all or part of the stops present, if any.

[0014] In some embodiments, at least a portion of the retaining element carrying said stop is elastically deformable in the transverse direction, between the neutralized state and the armed state. The elastically deformable nature ensures not only deformation without wear, but also automatic resetting of the retaining element in the absence of opposing forces, particularly in the absence of actuation of the actuator.

[0015] For example, said portion may comprise a locally refined portion of the retaining element, which facilitates its elastic deformation. In certain embodiments, the actuator is rotatable in the sheath. The actuation gesture is therefore particularly pleasant for the user and this limits untimely actuations.

[0016] In some embodiments, the actuator is configured to override the retaining element regardless of the direction in which the actuator is rotated. In other words, the actuator can be configured to be moved relative to the sleeve in one direction and in the opposite direction, both directions enabling the retaining element to be overridden. The packaging device thus offers great flexibility of use.

[0017] In some embodiments, the actuator and the sheath are engaged with each other so as to limit the stroke of the actuator. By limiting the stroke of the actuator, excessive actuation of the actuator prevents a part of the packaging device, such as the retaining element or the return system, from breaking. In addition, the packaging device gives the impression of robustness.

[0018] When the actuator is moved, especially parallel to the ring, the tab moves inside the slot until it rests on the ring, then pushes the ring, which increases its diameter and neutralizes it. A split ring is a simple, robust and inexpensive device. The split ring can be a circlip.

[0019] In some embodiments, the retaining element comprises a portion integral with the sheath in the direction of movement of the actuator. Said portion is therefore fixed relative to the sheath in the direction of movement, but it can be movable relative to the sheath in other directions. In these embodiments, the neutralization of the retaining element is all the more effective, since a part of the retaining element - said integral portion - is kept stationary relative to the sheath while another part of the retaining element - the one on which the actuator acts - is moved relative to the sheath.

[0020] In some embodiments, the support comprises a plurality of annularly distributed hooks configured, in the retracted position, to cooperate with the retaining element. It is understood that it is not necessary for all the hooks to cooperate permanently with the retaining element; moreover, providing more hooks than points of cooperation allows greater flexibility in positioning the support. In addition, distributing the cooperation between the support and the retaining element over several hooks allows for the distribution of forces and guarantees good centering of the device, which makes it more reliable.

[0021] In some embodiments, a first member of the bracket and the actuator engages a guide of a second member of the bracket and the actuator. The bracket and the actuator cooperate such that movement of the actuator causes, as previously discussed, movement of the bracket. The first member may include a follower member that engages and follows the guide, for example, in the form of a protrusion, a slot, a pin, etc. Other types of cooperation are also contemplated.

[0022] The guide may form a stop opposing the return force, in particular when the support is in the release position. The guide may also be configured so that the release position is a single predetermined position, guaranteeing in particular a certain orientation of the support relative to the actuator and / or the sheath. For example, the guide may have a general triangular shape, in particular the tip of which cooperates with said first element in the release position.

[0023] In some embodiments, the packaging device further comprises a product container provided on the support. The container may be removable from the support, whereby the packaging device functions as a storage case, possibly refillable and usable with different products.

[0024] In some embodiments, the product container is a lipstick mechanism. Other contemplated containers include bottles, sprays, and other dispensing devices. Brief description of the drawings

[0026] THE figures 1 à 5 illustrate a packaging device 100 according to one embodiment.

[0027] As indicated previously, the packaging device 100 comprises a sheath 10. In this case, the sheath 10 is tubular, and more particularly cylindrical around an axis X defining a longitudinal direction. A radial direction is a direction perpendicular to this axis X and intersecting this axis X. Similarly, an axial or longitudinal plane is a plane containing the axis X of the sheath, and a radial plane is a plane perpendicular to this axis X. A circumference is understood to be a circle belonging to a radial plane and whose center belongs to the axis X of the sheath. A tangential or circumferential direction is a direction tangent to a circumference; it is perpendicular to the axis X of the sheath but does not pass through this axis.

[0028] Unless otherwise specified, the adjectives interior and exterior are used with reference to a radial direction so that the interior part of an element is, in a radial direction, closer to the axis than the exterior part of the same element.

[0029] The sheath 10 is here of circular section, but other sections are envisaged as long as they allow the actuation of the actuator 60 which will be described later, for example its rotation.

[0030] The sheath 10 has two opposite ends 12, 14. One of these ends, illustrated in the upper part in the figures, is an open end 12. The other end 14, illustrated in the lower part in the figures, is intended to be closed by a base 20 which will be described later.

[0031] The packaging device 100 further comprises a support 30 for a product, such as a cosmetic product. The product may be provided in solid, liquid, pasty or powder form. Typically, the product may be a lipstick. If appropriate and as illustrated in the figures, the product may be provided in a container 32 ad hoc, possibly provided with dispensing means (pump, cam, spray, etc., not illustrated in the figures). Alternatively, the product can be provided directly on the support 30, without an intermediate container. Subsequently, for the sake of brevity but without loss of generality, the case where the product is contained in a container 32 will be described. The fact of providing a container 32 independent of the support 30 makes it possible to detach the container 32 for the application of the product, the packaging device 100 then being essentially a storage case. In any event, the fact that the container 32 is independent of the support 30 makes it possible to make the packaging device 100 compatible with different products, and possibly refillable.

[0032] The support 30 is mounted to move inside the sheath 10, more particularly to move in the longitudinal direction X. The support 30 is intended to move between a retracted position, illustrated in the figure 2 , in which the product is not normally accessible, and a release position, illustrated in the figure 3 , in which the support 30 facilitates access to the product. Typically, in the released position, the container 32 can extend beyond the sheath 10, while in the retracted position, the container 32 is housed in the sheath 10, preferably entirely housed in the sheath 10.

[0033] In this case, the support comprises a base 34 from which a sleeve 36 projects, here tubular, the base 34 and the sleeve 36 together defining a receptacle capable of receiving the container 32. More precisely, the sleeve 36 projects longitudinally from the base, towards the open end 12 of the sheath 10. Instead of being tubular, the sleeve 36 could comprise one or more claws capable of cooperating with the container 32, or could take any other shape configured to removably secure the container 32 to the support 30. In this case, the container 32 is force-fitted into the sleeve 36, where it is held by friction. The level of friction obtained can be adjusted so that the container 32 can be manually removed from the support 30.

[0034] The holder 30 may be fitted with a cap 38 to enclose the container 32 between the cap 38, the jacket 36 and the base 34, as shown in FIG. figure 2 . For example, the cap 38 may rest on one end of the container 32 and be located at a distance from the jacket 36, as illustrated in the figure 2 . According to another example, the cap 38 can rest on the free end of the jacket 36, and optionally be located at a distance from one end of the container 32, so that it does not risk accidentally actuating a possible dispensing head provided at the top of the container 32.

[0035] In this embodiment, the cap 38 extends the support 30. The cap 38 can be designed to be housed entirely in the sheath 10, at least in the retracted position of the support 30. Furthermore, it is noted that the jacket 36 is housed entirely in the sheath, both in the retracted position of the support ( figure 2 ) than in the release position ( figure 3 ).

[0036] As mentioned previously, the cap 38 is optional and may not be provided, or may be replaced by other removable or non-removable elements, such as a spray push button, a decorative element, etc., such elements being able to be associated with the container 32.

[0037] The conditioning device 100 further comprises a spring 40, one end of which bears on the support 30, more particularly on the face of the base 34 opposite the jacket 36. The support 30 can be free to rotate around the longitudinal direction X relative to the spring 40. In this embodiment, the spring 40 is a helical spring, however other types of springs, or more generally other return systems capable of exerting a return force, are envisaged.

[0038] The packaging device 100 further comprises a retaining element 50, intended to hold the support 30 in the retracted position. The retaining element 50 comprises a split ring.

[0039] In this embodiment, more particularly, the retaining element 50 comprises a portion, called intermediate portion 52, having a notch 53 configured to cooperate with a corresponding projection 13 of the sheath 10 (see figure 2 ). A portion of the retaining element 50 is thus secured at least in rotation around the longitudinal direction X relative to the sheath 10. More generally, other assemblies would be possible to secure in rotation the sheath 10 and the retaining element 50.

[0040] Furthermore, the retaining element 50 can also rest between internal shoulders of the sheath 10 (see figure 2 ), whereby it is substantially blocked in longitudinal translation relative to the sheath 10, even if a certain amount of play is acceptable.

[0041] Flanks 54, in a ring sector, extend on either side of the intermediate portion 52 and are extended by fins 56 which are thinner than the flanks 54. The thinning of the fins 56 may include a reduction in their external diameter, in order to provide a radial space between the fins 56 and the sheath 10 in which the fins 56 can deform.

[0042] The fins 56 face each other on either side of a slot 58.

[0043] As is more clearly evident from the figures 1 And 4, to retain the support 30 in the retracted position, the retaining element 50 may have at least one stop, in this case three stops 55 equally distributed angularly around the longitudinal direction X. The number and position of the stops 55 may vary. In this case, a stop 55 is provided on the intermediate portion 52 and a stop 55 is provided on each fin 56. The fins 56 form portions of the retaining element 50 that are elastically deformable in the transverse direction. Due to their refinement, the fins 56 can deform preferentially relative to the rest of the retaining element 50.

[0044] In the retracted position, the stops 55 therefore cooperate with the support 30. For example, as indicated previously, the support 30 may comprise a plurality of hooks 37 annularly distributed and configured, in the retracted position, to cooperate with the retaining element 50 and more particularly with the stops 55. In this case, each hook 37 projects from the support 30, in particular from the base 34, opposite the jacket 36. Each hook 37 defines a hooking space open towards the retaining element 50, therefore here radially towards the outside. The hooking space, defined between the heads of the hooks 37 and the base 34 from which the hooks project, is capable of receiving the stops 55. Each stop 55 may be engaged by one or more hooks 37, the latter case being shown in the figure 4 The stops 55, which extend transversely, are configured to block the longitudinal movement of the support 30 by retaining the hooks 37.

[0045] Furthermore, the packaging device 100 finally comprises an actuator 60 whose movement causes the support 30 to move between the retracted position and the disengaged position. In this embodiment, the actuator 60 is tubular around the longitudinal direction X, more particularly cylindrical with a circular section. The actuator 60 has a first end 61, illustrated in the upper part in the figures, which is open, and a second end 63, illustrated in the lower part in the figures, which is also open.

[0046] In this embodiment, the actuator 60 is mounted to move in the sheath 10, in particular to move in rotation, typically around the longitudinal direction X.

[0047] The first end 61 may comprise recesses for the insertion of corresponding legs of a ring 62. The ring 62 may be provided to facilitate the handling of the actuator 60, as will be seen later. As an alternative to the fitting attachment shown, the ring 62 may be assembled to the actuator 60, in particular made integral in rotation, by any suitable fitting or more broadly by any suitable means (gluing, etc.), or even be made integral with the actuator 60. Furthermore, the ring 62 may be radially wider than the actuator 60. The open end 61 or the ring 62 extends beyond the sheath 10 to be accessible and handled by the user.

[0048] Furthermore, protrusions 66 may be provided on the actuator 60 and protrude towards the sheath 10, more precisely to engage in corresponding grooves 16 of the sheath 10. The protrusions 66 may be provided on tabs of the sheath 10 to facilitate the elastic deformation of the sheath 10. Thus, the insertion of the protrusions 66 into the grooves 16 is easy and is done without damage. The grooves 16 extend over a limited angular sector, for example less than or equal to 90°, which makes it possible to limit the angular travel of the actuator 60 relative to the sheath 10. Of course, any other means of limiting the angular travel of the actuator 60 relative to the sheath 10 can be envisaged, to achieve the fact that the actuator 60 and the sheath 10 are engaged with each other (here, one inside the other) so as to limit the travel of the actuator 60.Furthermore, the number and position of the protrusions 66 and / or the corresponding grooves 16 may vary.

[0049] Furthermore, if the positioning of the grooves 16 and the protrusions 66 respectively near the ends 12, 61 facilitates the fitting of the sheath 10 onto the actuator 60, this is not absolutely necessary and other positions can be envisaged.

[0050] At the second end 63, the actuator 60 comprises a tab 65 configured to engage in the slot 58 of the retaining element 50, as shown more particularly in figure 4 The tab 65 projects longitudinally on the actuator 60, towards the retaining element 50.

[0051] Furthermore, as shown by the figures 1 à 3 , the actuator 60 comprises a guide 64. Here, the actuator 60 actually comprises two diametrically opposed guides 64, but without loss of generality, a single guide 64 will be described below, it being understood that the number and arrangement of the guides may vary and that the guides may or may not be identical to each other.

[0052] The guide 64 is here provided in the form of a cutout of the actuator 60, but it could comprise a groove, a rail, etc. The actuator 60 therefore forms a second element, with the guide 64 of which a first element engages, namely here the support 30. More precisely, the support 30 comprises at least one lug 35, for example as many lugs as the actuator comprises guides 64. The lug 35 engages with (here, in) the guide 64 when the support 30 is fitted into the actuator 60. The lug 35 can project from the support 30, here from the sleeve 36, in the direction of the actuator 60.

[0053] The cooperation between the support 30 and the actuator 60 defines the positions that the support 30 can take relative to the sheath 10, and in particular the retracted position and the release position.

[0054] To facilitate the insertion of the lug 35 into the guide 64, the guide 64 can open on one end of the actuator 60, in this case the end 63 opposite the open end 61. The figure 1 illustrates an opening 64a of a smaller size than the guide 64 itself, but an opening 64a as wide as, or even wider than, the guide 64 could also be provided. This is not necessary, however, as the lug 35 can also be inserted by taking advantage of an elastic deformation of the actuator 60 or the support 30.

[0055] The assembly of the packaging device 100 can be carried out in the following manner. Unless otherwise stated or constrained by the context, the order of the steps can be modified.

[0056] The container 32 is placed in the support 30, in this case inside the sleeve 36. The container 32 can be fixed to the support 30, reversibly or not. The actuator 60 is fitted onto the support 30, the lug 35 being inserted through the opening end of the guide 64, more precisely through the opening 64a.

[0057] The retaining element 50 is inserted into the sheath 10 and the retaining element 50 is rotationally secured to the sheath 10. The container-support-actuator assembly can be placed in the sheath 10, the tab 65 of the actuator 60 cooperating with the slot 58 of the retaining element 50 and the hooks 37 of the support 30 cooperating with the stops 55 of the retaining element 50.

[0058] The insertion of the various elements into the sheath 10 can be done via one or other of the ends 12, 14, typically depending on the shoulders provided inside the sheath 10. The order of the steps is adapted to the direction of assembly.

[0059] The ring 62 is assembled to the actuator 60. Furthermore, the spring 40 is installed between the support 30 and the base 20 which is added to close the packaging device 100. The base 20 can be assembled to the sheath 10 by a bayonet type assembly. However, any other assembly can be envisaged.

[0060] The spring 40, which is an example of an elastic component or more generally of a return system, is dimensioned so as to be prestressed when it is located between the support 30 and the base 20. More precisely, the spring 40 is prestressed in compression, in the sense that it tends to move the support 30 away from the base 20. In this, the spring 40 forms a return system configured to move the support 30 towards the release position, as will be seen later. The return system (the spring 40) is therefore configured to return the support 30 in a first direction, namely here the longitudinal direction.

[0061] As it emerges from the figure 2 , the actuator 60 can be longitudinally held in the sheath 10: at the end 61, the ring 62 extends radially beyond the actuator 60, and exceeds the internal diameter of the sheath 10; at the end 63, the sheath 10 rests on the retaining element 50. In other words, the sheath 10 is longitudinally held between the ring 62 and the retaining element 50. The protuberances 66 also contribute to this holding.

[0062] The packaging device 100 being assembled, the actuator 60 has a part accessible to the user, in this case the ring 62. The ring 62 nevertheless does not allow the user to remove the actuator from the sheath 10, thanks to the longitudinal blocking by the protuberances 66.

[0063] In this embodiment, the actuator 60 is fixed in longitudinal translation within the sheath 10. Furthermore, the actuator 60 can be movable in rotation within the sheath 10, in particular around the longitudinal direction X. Here, the actuator 60 can be driven in rotation by simple action of the user on the ring 62. However, other, more sophisticated, rotational drive mechanisms can be considered.

[0064] There figure 2 illustrates the packaging device 100 in the retracted position of the support 30. As illustrated in the figure 4 , already described, the support 30 is held in the retracted position thanks to the fact that the retaining element 50 has at least one stop 55 provided so as to limit the movement of the support 30 under the effect of the return force of the spring 40 when the support 30 is in the retracted position. More precisely, the stops 55 are hooked by the hooks 37 of the support. Thus, the lug 35 of the support 30 is in the stable position referenced A on the principle diagram of the figure 5 . The support 30 is located in the position of the figure 2 where, for example, the cap 38 is level with the ring 62.

[0065] When the user wishes to release the container 32 for product dispensing, he can rotate the ring 62. As illustrated in the figure 5 , the guide 64 is such that in the retracted position, the actuator 60 can be rotated in one direction or in the opposite direction, indifferently.

[0066] The user therefore drives the actuator 60, in this case in rotation, in order to move it along a certain stroke which can be limited by the protrusions 66 described previously. At the end of this stroke, the lug 35 is in position B of the figure 5 (or in the symmetrical position), this position being an intermediate and unstable position. The rotation of the actuator 60 has caused a rotation of its tab 65, which has taken support on the free end of a fin 56 and pushed it, to the point of deforming it elastically, in this case radially outwards. In doing so, at least one of the stops 55 is displaced transversely, here along a radial plane, as a result of which this stop 55 no longer engages a hook 37: the stop 55 is therefore neutralized.

[0067] The remaining stops 55 are no longer sufficient, by their number, their location or their resistance, to counter the return force of the spring 40. It follows that the retaining element 50 is neutralized, in the sense that it no longer retains the support 30. Under the effect of the return force, the support 30 therefore passes into the release position illustrated in the figure 3 , and the lug 35 is in the stable position C, illustrated in the figure 5 In this position, the user can easily remove the cap 38, dispense product contained in the container 32 and replace the cap 38, or extract the container 32, for example a lipstick mechanism, then reinsert it on the support 30 after using it.

[0068] During the transition of the support 30 to the release position, the user has normally released the ring 62, so that the actuator 60 is free to rotate relative to the sheath 10. By elasticity, the retaining element 50 tends to return to its resting shape, and therefore acts on the tab 65 so that the actuator 60 returns to its original position. At the same time, during the longitudinal translation of the support 30, the lug 35 abuts against an inclined cam surface 67 of the guide 64, which also tends to drive the actuator 60 in rotation and, more generally, to make it return to its starting position. The retaining element 50 is therefore configured to automatically reset itself in the absence of actuation of the actuator 60. Of course, the automatic reset could be obtained solely through the elasticity of the retaining element 50 or solely through the cam surface of the guide 67, or in a different manner.

[0069] In order to prevent the support 30 from coming completely out of the sheath 10, the movement of the support 30 in the longitudinal direction can be limited by a stop 68 of the guide 64, opposing the return force of the spring 40. In addition, when the lug 35 is pressed against the stop 68 when the support moves into the release position, a clicking noise is heard, which gives the user the feeling that the release position has been reached, and therefore the feeling that the packaging device is operating correctly.

[0070] The support 30 is held in the disengaged position under the effect of the return force of the spring 40. In this position, the actuator 60 cannot be moved, thanks to the fact that the guide 64 and the lug 35 have, in the disengaged position (position C on the figure 5 ), substantially complementary shapes in the circumferential direction (direction of actuation of the actuator 60).

[0071] To move the support 30 from the disengaged position to the retracted position, the user must press on the support 30 with sufficient force to overcome the force exerted by the spring 40. To do this, the user can press on the cap 38 or re-engage the container 32, the cap 38 or the container 32 in turn pressing on the support 30. In doing so, the lug 35 circulates in a free space of the guide 64, until the hooks 37 of the support 30 cooperate again with the stops 55 of the retaining element 50. The hooks 37 can re-engage the stops 55 by a form of snap-fastening: the hooks 37 and the fins 56 push each other so as to deform elastically to allow the hooks 37 to pass beyond the stops 55, after which the hooks 37 and the stops 55 resume their rest position in which the stops 55 oppose the movement of the hooks 37 under the effect of the return force of the spring 40.The transition to the retracted position by snap-fastening can be facilitated by bevels provided on the hooks 37 (see . figure 2 ) and / or on the stops 55.

[0072] When the user releases the pressure at the end of the movement, the spring 40 presses the hooks 37 against the stops 55. A clicking noise is then heard, which gives the user the feeling that the retracted position has been reached, and therefore the feeling that the packaging device is working properly. The lug 35 is then in position A on the figure 5 .

[0073] In the present embodiment, the guide is generally triangular or delta shaped, as seen in the figures 1 And 5; the tip of the triangle, near the stop 68, corresponds to a single position of the actuator 60 relative to the support 30, typically in the disengaged position, while the base of the triangle, opposite the tip, corresponds to a plurality of possible positions of the actuator 60 relative to the support 30, typically in the retracted position. The cam surfaces 67 connect the base to the tip. The sides of the triangle may be rounded, as illustrated, in order to facilitate rapid actuations. Other shapes are of course conceivable.

[0074] If desired, the support 30 may be held in a predetermined orientation relative to the sleeve 10, for example by extending the lug 35 so that it engages in a longitudinal groove or slot in the sleeve 10. If desired, a decorative hoop may be added to mask the longitudinal slot.

[0075] Although the present description refers to specific exemplary embodiments, modifications may be made to these examples without departing from the general scope of the invention as defined by the claims. For example, in addition to the variations already indicated throughout the description, the following modifications could be envisaged: the lug 35 could be provided on the actuator 60 and the guide 64 on the support 30; more generally, all the mechanical cooperations could be reversed; the translation and rotation directions could be exchanged.

[0076] More generally, individual features of the various embodiments illustrated or mentioned may be combined in additional embodiments. Therefore, the description and drawings should be considered in an illustrative rather than restrictive sense.
