Description

PRODUCT PACKAGING DEVICE

DESCRIPTION

Technical area

This presentation relates to a packaging device, and more particularly a device for packaging a product, in particular a cosmetic product.

Prior technique

[0002] A packaging device, in particular for cosmetic products of the lipstick, cream or vaporizer type, must be able to be easily transported, for example in a bag or a handbag, and be used frequently. Thus, the packaging device must be light and compact, and allow easy extraction of the product it contains, that is to say requiring little effort and being able to be carried out in a simple manner, without the user should pay particular attention to the maneuver he is performing. The device must also make it possible to store the product by means of a simple maneuver which does not require any particular attention from the user either. In addition, this storage must be reliable, that is to say that an untimely exit of the product must be avoided.

[0003] International application WO 2014/096651, by 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 conditioning device which, although not necessarily using magnets, has a level of reliability that is at least as good.

Disclosure of Invention [0004] To this end, the present presentation relates to a device for packaging a product, in particular a cosmetic product, comprising a sheath having an open end, a support for the product, movable in the sheath between a retracted position and a release position, an actuator capable of neutralizing a retaining element and thus causing the support to move from the retracted position to the release position under the effect of a return force, the retaining element being configured to reset automatically in the absence of actuation of the actuator.

[0005] The support can carry the product or an intermediate container containing the product, such as a reservoir, provided or not with a mechanism for dispensing, spraying, etc.

[0006] When the support is in the release position, it is subjected to the force exerted by the return system, which tends to keep 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.

[0007] The retaining element retains the support in the retracted position. Neutralizing the retaining element amounts to rendering the retaining element unable to perform 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 release position; then intervenes the restoring force which recalls the support towards the release position. The resetting of 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.

The restoring force can 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 can be exerted by a restoring system. The restoring force can be attractive or repulsive.

[0009] Thanks to the fact that the retaining element is automatically reset in the absence of actuation of the actuator, typically when the actuator is released by the user after allowing the support to pass in release position, the support can very easily be retracted after distribution of the product, by a simple force countering the return force. The device is therefore of particularly simple construction and use, which makes it inexpensive and pleasant for the user.

[0010] In addition, maintaining the support in the retracted position relies on a retaining element, which can be implemented reliably and does not necessarily use magnetic cooperation. If a magnet is nevertheless used as a return system, it may be relatively less powerful than in the state of the art insofar as the holding in the retracted position is ensured by the retaining element. As a result, the environmental impact of the packaging device is much improved.

In some embodiments, the support is longitudinally movable between the retracted position and the release position, and the actuator is able to neutralize at least one stop of the retaining element by moving said stop transversely. Thus, the abutment of the retaining element, which opposes the restoring 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 displacement of the support.

[0012] In certain embodiments, the retaining element comprises a plurality of said stops, distributed circumferentially. The support is therefore retained more reliably in the retracted position. Although only one abutment is described below, the properties set out can apply to all or part of the abutments present, where applicable.

[0013] In certain embodiments, at least a portion of the retaining element bearing said abutment is elastically deformable in the transverse direction, between the neutralized state and the armed state. The elastically deformable nature not only ensures wear-free deformation, but also the automatic resetting of the retaining element in the absence of forces opposing it, particularly in the absence of actuation of the actuator.

[0014] For example, said portion may comprise a locally thinned portion of the retaining element, which facilitates its elastic deformation

[0015] In some embodiments, the actuator is rotatable in the sheath. The actuation gesture is therefore particularly pleasant for the user and this limits untimely actuation. [0016] In certain embodiments, the actuator is configured to neutralize 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 sheath in one direction and in the opposite direction, the two directions making it possible to neutralize the retaining element. The packaging device thus offers great flexibility of use.

[0017] In certain embodiments, the actuator and the sheath are engaged with each other so as to limit the travel of the actuator. The travel of the actuator being limited, excessive actuation of the actuator is prevented from breaking a part of the packaging device, for example the retaining element or the return system. In addition, the conditioning device gives an impression of robustness.

[0018] In some embodiments, the retaining element comprises a split ring and the actuator comprises a tab engaged in the slot of the ring. When the actuator is moved, in particular parallel to the ring, the lug moves inside the slot until it comes to rest 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 may be a circlip.

[0019] In certain embodiments, the retaining element comprises a portion secured to 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 immobile with respect 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 certain 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, the fact of providing more hooks than points of cooperation allows greater flexibility in positioning the support. In addition, the distribution of the cooperation between the support and the element of retained on several hooks distributes the forces and guarantees good centering of the device, which makes it more reliable.

[0021] In certain embodiments, a first element among the support and the actuator engages with a guide of a second element among the support and the actuator. The support and the actuator cooperate so that the movement of the actuator causes, as previously explained, a movement of the support. The first element may comprise a follower element which engages with and follows the guide, for example in the form of a projection, a slot, a pin, etc. Other types of cooperation are also envisaged.

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

In some embodiments, the packaging device further comprises a product container provided on the support. The container can be removable relative to the support, the packaging device then functioning as a storage case, optionally rechargeable and usable with different products.

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

detailed description

[0031] Figures 1 to 5 illustrate a conditioning device 100 according to one embodiment.

As indicated above, the packaging device 100 comprises a sleeve 10. In this case, the sleeve 10 is tubular, and more particularly cylindrical around an axis X defining a longitudinal direction. A radial direction is a direction perpendicular to this X axis and intersecting this X axis. Similarly, an axial or longitudinal plane is a plane containing the X axis of the sheath, and a radial plane is a plane perpendicular to this X axis. circumference is understood as a circle belonging to a radial plane and whose center belongs to the X axis of the sleeve. 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.

[0033] 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. .

The sheath 10 is here of circular section, but other sections are considered when they allow the actuation of the actuator 60 which will be described later, for example its rotation.

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.

The packaging device 100 also comprises a support 30 for a product, such as a cosmetic product. The product can be supplied in solid, liquid, paste or powder form. Typically the product may be a stick of lipstick. If necessary and as illustrated in the figures, the product may be provided in an ad hoc container 32, optionally provided with dispensing means (pump, cam, vaporizer, 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 case, 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 optionally refillable.

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

In this case, the support comprises a base 34 from which projects a sleeve 36, here tubular, the base 34 and the sleeve 36 together defining a receptacle capable of receiving the container 32. More specifically, the sleeve 36 projects longitudinally from the base, in the direction of 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 form configured to secure , removably, the container 32 with the support 30. In this case, the container 32 is mounted by force in 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.

[0039] The support 30 can be combined with a cap 38 to enclose the container 32 between the cap 38, the sleeve 36 and the base 34, like the shown in Figure 2. For example, the cap 38 can rest on one end of the container 32 and be located at a distance from the jacket 36, as illustrated in Figure 2. According to another example, the cap 38 can rest on the free end of the jacket 36, and optionally be at a distance from one end of the container 32, so that it does not risk inadvertently actuating any dispensing head provided at the top of the container 32.

In this embodiment, the cap 38 extends the support 30. The cap 38 can be provided to be housed entirely in the sheath 10, at least in the retracted position of the support 30. Furthermore, it is noted that the sleeve 36 is housed entirely in the sheath, both in the retracted position of the support (Figure 2) and in the release position (Figure 3).

[0041] As mentioned above, the cap 38 is optional and may not be provided, or may be replaced by other removable or non-removable elements, such as a vaporizer push button, a decorative element, etc., of such elements can be associated with the container 32.

The packaging device 100 also comprises a spring 40, one end of which rests on the support 30, more particularly on the face of the base 34 opposite the sleeve 36. The support 30 can rotate freely around the longitudinal direction X with respect 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 .

The packaging device 100 also comprises a retaining element 50, intended to hold the support 30 in the retracted position. In this embodiment, retainer 50 comprises a split ring, however other forms of retainer may be considered.

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). Part of the retaining element 50 is thus secured at least in rotation around the longitudinal direction X with respect to the sheath 10. More generally, other assemblies would be possible to secure the sheath 10 and the retaining element in rotation. 50. 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 play is acceptable.

Flanks 54, in a ring sector, extend on either side of the intermediate portion 52 and are extended by fins 56 that are thinner with respect to the flanks 54. The thinning of the fins 56 can comprise a decrease in their outer diameter, in order to provide a radial space between the fins 56 and the sheath 10 in which the fins 56 can deform.

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

As is apparent more clearly from 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 evenly distributed angularly around the longitudinal direction X. The number and position of 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.

In the retracted position, the stops 55 therefore cooperate with the support 30. For example, as indicated above, the support 30 may comprise a plurality of hooks 37 distributed annularly and configured, in the retracted position, to cooperate with the element of retainer 50 and more particularly with the stops 55. In this case, each hook 37 protrudes from the support 30, in particular from the base 34, opposite the sleeve 36. Each hook 37 defines a hooking space open towards the retaining element 50, so here radially outwards. The hooking space, defined between the heads of the hooks 37 and the base 34 from which the hooks protrude, is able to accommodate the stops 55. Each stop 55 can be engaged by one or more hooks 37, the latter case being represented on Figure 4. The stops 55, which extend transversely, are configured to block the longitudinal movement of the support 30 by retaining the hooks 37.

Furthermore, the packaging device 100 finally comprises an actuator 60 whose movement causes the movement of the support 30 between the retracted position and the release position. In this mode of 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.

In this embodiment, the actuator 60 is mounted in the sheath 10, in particular mobile in rotation, typically around the longitudinal direction X.

The first end 61 may include 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 fixing by interlocking represented, the ring 62 can be assembled with the actuator 60, in particular made integral in rotation, by any suitable interlocking or more widely by any suitable means (gluing, etc.), or even come from material with the actuator 62. Furthermore, the ring 62 can be radially wider than the actuator 60. The open end 61 or the ring 62 extends beyond the sleeve 10 to be accessible and manipulated by the user.

Furthermore, protrusions 66 can be provided on the actuator 60 and protrude in the direction of the sheath 10, more precisely to engage in corresponding grooves 16 of the sheath 10. The protrusions 66 can be provided on tabs of the sheath 10 to facilitate the elastic deformation of the sheath 10. Thus, the insertion of the protuberances 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 with respect to the sheath 10. Of course, any other means of limiting the travel angle of the actuator 60 with respect to the sheath 10 can be considered, to achieve the fact that the actuator 60 and the sheath 10 are engaged with each other (here, one inside the other) so to limit the travel of the actuator 60. Furthermore, the number and the position of the protrusions 66 and/or of the corresponding grooves 16 can vary.

[0054] Furthermore, if the positioning of the grooves 16 and the protrusions 66 respectively close to the ends 12, 61 facilitates the fitting of the sheath 10 on the actuator 60, this is absolutely not necessary and other positions can be envisaged.

[0055] At the second end 63, the actuator 60 may include 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 protrudes longitudinally on the actuator 60, in the direction of the retaining element 50.

Furthermore, as shown in Figures 1 to 3, the actuator 60 includes a guide 64. Here, the actuator 60 actually includes two diametrically opposed guides 64, but without loss of generality, we will describe later a single guide 64, 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.

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

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

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. FIG. 1 illustrates an opening 64a of smaller size than the guide 64 strictly speaking, but an opening 64a as wide, or even wider than the guide 64 could also be provided. However, this is not necessary, the lug 35 can also be inserted by taking advantage of an elastic deformation of the actuator 60 or of the support 30.

The packaging device 100 can be mounted as follows. Unless otherwise stated or constrained by the context, the order of the steps may be modified.

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, so reversible or not. The actuator 60 is fitted onto the support 30, the lug 35 being inserted through the emerging end of the guide 64, more precisely through the opening 64a.

The retaining element 50 is inserted into the sheath 10 and the retaining element 50 is integral in rotation with 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.

The insertion of the various elements into the sheath 10 can be done by one or the other of the ends 12, 14, typically depending on the shoulders provided inside the sheath 10. The order of the steps is suitable for the mounting direction.

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 conditioning device 100. The base 20 can be assembled to the sheath 10 by a bayonet type mounting. However, any other assembly can be envisaged.

The spring 40, which is an example of an elastic component or more generally of a return system, is dimensioned so as to be pre-stressed when it is 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.

As shown in Figure 2, the actuator 60 can be held longitudinally in the sleeve 10: at the end 61, the ring 62 extends radially beyond the actuator 60, and exceeds the diameter interior of the sheath 10; at the end 63, the sleeve 10 rests on the retaining element 50. In other words, the sleeve 10 is longitudinally held between the ring 62 and the retaining element 50. The protrusions 16 also contribute to this holding . 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 does not however allow the user to remove the actuator from the sheath 10, thanks to the longitudinal blocking by the protrusions 16.

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

[0069] Figure 2 illustrates the packaging device 100 in the retracted position of the support 30. As illustrated in Figure 4, already described, the support 30 is held in the retracted position thanks to the fact that the retaining element 50 has a least one stop 55 provided so as to limit the movement of the support 30 under the effect of the restoring 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 in the block diagram of Figure 5. The support 30 is in the position of Figure 2 where, for example, the cap 38 is level with ring 62.

[0070] When the user wishes to release the container 32 with a view to dispensing the product, he can cause the ring 62 to rotate. As illustrated in Figure 5, the guide 64 is such that in the retracted position, the actuator 60 can be driven in rotation in one direction or in the opposite direction, indifferently.

The user therefore drives the actuator 60, in this case in rotation, in order to move it according to a certain stroke which can be limited by the protrusions 66 described above. At the end of this stroke, the lug 35 is in position B of FIG. 5 (or in the symmetrical position), this position being an intermediate and unstable position. The rotation of the actuator 60 caused a rotation of its tab 65, which rested on the free end of a fin 56 and pushed it, to the point of deforming it elastically, in this case radially towards the 'outside. In doing so, at least one of the stops 55 is moved transversely, here along a radial plane, following which this stop 55 no longer engages the hook 37: the stop 55 is therefore neutralized. The remaining stops 55 are no longer sufficient, by their number, their location or their resistance, to counter the restoring 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 restoring force, the support 30 therefore passes into the release position illustrated in FIG. 3, and the lug 35 is in the stable position C, illustrated on figure 5. In this position, the user can easily remove the cap 38, dispense the product contained in the container 32 and replace the cap 38, or extract the container 32, for example a lipstick mechanism, then the re-insert on support 30 after using it.

During the passage 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 regain its shape at rest, and therefore acts on the leg 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 reset automatically in the absence of actuation of the actuator 60. Of course, the automatic resetting could be obtained only thanks to the elasticity of the retaining element 50 or only through the cam surface of the guide 67, or in yet another way.

In order to avoid the complete extension of the support 30 relative to the sheath 10, the movement of the support 30 in the longitudinal direction can be limited by a stop 68 of the guide 60, opposing the return force of the spring 40 In addition, when the lug 35 is pressed against the stop 68 when the support passes 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 of proper operation of the conditioning device.

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 in FIG. 5), shapes substantially complementary in the circumferential direction (direction of actuation of the actuator 60).

To move the support 30 from the release position to the retracted position, the user must press 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 reengage the container 32, the cap 38 or the container 32 pressing in turn 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 abutments 55 of the retaining element 50. The hooks 37 can reengage the abutments 55 by a form of snap-fastening: the hooks 37 and the fins 56 mutually push each other so as to deform elastically to allow the passage of the hooks 37 beyond the stops 55, after which the hooks 37 and the stops 55 return to 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. Passage into 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.

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 conditioning device is working properly. The lug 35 is then in position A in Figure 5.

In this embodiment, the guide is in the general shape of a triangle or delta, as can be seen in Figures 1 and 5; the tip of the triangle, close to the stop 68, corresponds to a single position of the actuator 60 relative to the support 30, typically in the release 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. Cam surfaces 67 connect the base to the tip. The sides of the triangle may be rounded, as shown, to facilitate quick actuations. Other shapes are of course possible.

[0079] If desired, the support 30 can be maintained in a predetermined orientation with respect to the sheath 10, for example by extending the lug 35 so that it engages in a longitudinal groove or slot. of the sheath 10. If necessary, a decorative hoop can be added to hide the longitudinal slot.

Although the present description refers to specific embodiments, modifications can 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 variants already indicated throughout the description, the following modifications could be considered:

- The pin 35 could be provided on the actuator 60 and the guide 64 on the support 30; more generally, all mechanical cooperation could be reversed;

- the directions of translation and rotation could be exchanged.

[0081] More generally, individual characteristics of the different embodiments illustrated or mentioned can be combined in additional embodiments. Accordingly, the description and the drawings should be considered in an illustrative rather than restrictive sense.
