Description

Packaging device for product

Technical Field

The present disclosure relates to packaging devices and, more particularly, to packaging devices for products, particularly cosmetics.

Background

Packaging devices, in particular for cosmetic products of the lipstick, cream or spray type, must be easy to transport, for example in bags or handbags, and frequently used. Therefore, the packaging device must be lightweight and space-compact and allow easy extraction of the product it contains, that is to say the user can easily do so with little effort and in a simple manner, without having to pay special attention to the operations it does. The device must also allow the storage of the product by simple operations without requiring special attention from the user. Furthermore, such storage must be reliable, i.e. accidental release of the product must be avoided.

International application WO2014/096651 by the applicant proposes a solution for maintaining cosmetics in a dispensing or release position, or in a storage or retracted position, using magnetic elements. While this solution is satisfactory, consumers now want to reduce the ecological impact of the packaged device, e.g. without magnets. Thus, there is a need for a new packaging device that has at least as good a level of reliability, although it does not necessarily use magnets.

Disclosure of Invention

To this end, the present disclosure relates to a packaging device for a product, in particular a cosmetic product, comprising a sleeve with an open end, a support for the product, which support is movable in the sleeve between a retracted position and a release position, and an actuator, which actuator is capable of disabling a retaining element and thus moving the support from the retracted position towards the release position under the influence of a restoring force, which retaining element is configured to automatically reset without actuation of the actuator.

The support may bear the product or an intermediate container containing the product, such as a storage tank, with or without means for dispensing, vaporizing, etc.

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 may be overcome by the force exerted by the user to return the support to the retracted position.

The retaining element retains the support in the retracted position. Failure (neutralisation) of the retaining element corresponds to disabling the retaining element from functioning to retain the support in the retracted position. The support being free to move between a retracted position and a release position when the retaining element is deactivated; a restoring force is then interposed to restore the support to the release position. Reset of the retention element is opposite to failure: after resetting, the holding element can again perform its function of holding the support in the retracted position; at this point, however, the support itself may no longer be in the retracted position. When the support returns to its retracted position, it will again be held.

The restoring force may be an elastic restoring force, e.g. similar to the restoring force exerted by an elastomer or spring, or may be a magnetic restoring force, e.g. exerted by a magnet. More generally, the restoring force may be applied by a restoring system. The restoring force may be attractive or repulsive.

Since the retaining element is automatically reset in case the actuator is not actuated (typically when the user releases the actuator after having brought the support into the release position), the support can be retracted very easily after product dispensing by a simple force opposite to the restoring force. The device thus has a particularly simple construction and manner of use, which makes it low-cost and easy for the user to use.

Furthermore, the retention of the support in the retracted position depends on a retaining element which can be realized reliably and does not have to employ magnetic cooperation. Nevertheless, if a magnet is used as the return system, it may be relatively weaker than the prior art magnet, as the retaining element ensures retention in the retracted position. Thus, the environmental impact of the packaged device is indeed improved.

In some embodiments, the support is longitudinally movable between a retracted position and a release position, and the actuator is capable of disabling at least one stop by laterally moving the stop of the retaining element. Thus, the stop of the holding element resists the restoring force in the retracted position, whereas the stop, conversely, passes the support when it is deactivated (i.e. when it is moved here transversely to the direction of movement of the support).

In some embodiments, the retaining element comprises a plurality of said stops distributed circumferentially. Thus, the support is held in the retracted position in a more reliable manner. Although a single stop is described below, the disclosed features may be applied to all or part of the stops present, as the case may be.

In some embodiments, at least a portion of the retaining element supporting the stop is elastically deformable in a lateral direction between a deactivated state (neutralized state) and a armed state (ARMED STATE). The feature of being elastically deformable ensures not only deformation without wear, but also automatic resetting of the holding element without a force opposing the holding element, in particular without actuation of the actuator.

For example, the portion may comprise a locally narrowed portion of the retaining element, which facilitates elastic deformation of the retaining element.

In some embodiments, the actuator is capable of rotational movement in the sleeve. Actuation gestures are therefore particularly desirable for users, and this limits accidental actuation.

In some embodiments, the actuator is configured to deactivate the retaining element regardless of the direction in which the actuator is driven to rotate. In other words, the actuator may be configured to move in one direction and in the opposite direction relative to the sleeve, both directions being capable of disabling the retaining element. Thus, the packaging device provides great flexibility of use.

In some embodiments, the actuator and sleeve engage each other, thereby limiting the travel of the actuator. The travel of the actuator is limited, which avoids over-actuation of the actuator that would damage a portion of the packaging (e.g., the retaining element or the return system).

In some embodiments, the retaining element comprises a split ring and the actuator comprises a protrusion engaged in the split ring. When the actuator is moved, in particular parallel to the split ring, the protrusion moves within the opening until it is supported on the split ring, and then pushes the split ring, thereby increasing the diameter of the split ring and disabling it. The split ring is a simple, robust and low cost device. The split ring may be a circlip (circlip).

In some embodiments, the retaining element comprises a portion that moves integrally with the sleeve in the direction of movement of the actuator. Thus, the part is fixed relative to the sleeve in the direction of movement, but it can be moved relative to the sleeve in other directions. In these embodiments, the failure of the retaining element is still more efficient, because one part of the retaining element, the integrally moving part, is held stationary relative to the sleeve, while another part of the retaining element, the part on which the actuator acts, is moved relative to the sleeve.

In some embodiments, the support includes a plurality of hooks angularly distributed and configured to cooperate with the retaining element in the retracted position. It should be understood that not all hooks must cooperate continuously with the retaining element; furthermore, providing more hooks than cooperating points will enable greater flexibility in positioning the support. Furthermore, the distribution of the cooperation between the support and the holding element over the plurality of hooks allows the distribution of forces and ensures a good centering of the device, which makes the device more reliable.

In some embodiments, a first element of the support and the actuator is engaged with a guide of a second element of the support and the actuator. The support and the actuator cooperate such that movement of the actuator causes movement of the support as previously described. The first element may comprise a follower element which cooperates with and follows the guide, for example in the form of a protrusion, a groove, a fork or the like. Other types of collaboration are also contemplated.

The guide may form a stop against the restoring force, in particular when the support is in the release position. Furthermore, the guide may be configured such that the release position is a predetermined unique position, in particular ensuring a specific orientation of the support relative to the actuator and/or the channel. For example, the guide may have a general shape of a triangle, for example with its apex cooperating with the first element in the release position.

In some embodiments, the packaging device further comprises a product container disposed on the support. The container may be removable with respect to the support, and the enclosure then serves as a storage tank, possibly refillable, and usable with different products.

In some embodiments, the product container is a lipstick mechanism. Other containers contemplated include vials, nebulizers, and other dispensing devices.

Detailed Description

Fig. 1 to 5 illustrate a packaging apparatus 100 according to one embodiment.

As previously described, the enclosure 100 includes the sleeve 10. In this particular case, the sleeve 10 is tubular and, more specifically, cylindrical about an axis X defining the longitudinal direction. The radial direction is a direction perpendicular to the axis X and intersecting the axis X. Likewise, an axial or longitudinal plane is a plane containing the axis X of the sleeve, while a radial plane is a plane perpendicular to this axis X. The circumference is understood as a circle belonging to a radial plane, the centre of which belongs to the axis X of the sleeve. The tangential or circumferential direction is the direction tangential to the circumference; which is perpendicular to the axis X of the sleeve but does not pass through it.

The adjectives "inner" and "outer" are used with reference to a radial direction, unless otherwise indicated, such that the "inner" of an element is closer to the axis in the radial direction than the "outer" of the same element.

Here, the sleeve 10 has a circular cross section, but other cross sections are also contemplated, as long as they allow actuation of an actuator 60 (described below), such as rotation thereof.

The sleeve 10 has two opposite ends 12, 14. One of these ends, as shown in the upper part of the figure, is an open end 12. The other end 14, as shown in the lower part of the figure, is intended to be closed by a seat 20, which will be described hereinafter.

In addition, the packaging unit 100 further includes a support 30 for a product (e.g., cosmetic product). The product may be provided as a solid, liquid, paste or powder form. Typically, the product may be a lipstick. If necessary and as shown in the figures, the product may be provided in an ad hoc container 32, which may be provided with dispensing means (pumps, cams, sprayers, etc., not shown in the figures). Alternatively, the product may be provided directly on the support 30 without the need for an intermediate container. Hereinafter, for brevity and without loss of generality, the case of containing the product in the container 32 will be described. By providing the container 32 independent of the support 30, so that the container 32 can be removed to apply the product, the packaging apparatus 100 is then essentially a storage box. In any event, the fact that the container 32 is independent of the support 30 enables the packaged device 100 to be compatible with different products and to be refilled.

The support 30 is movably mounted inside the sleeve 10, more particularly movably mounted inside the sleeve 10 in the longitudinal direction X. The support 30 is arranged to move between a retracted position, shown in fig. 2, in which the product is normally not accessible, and a release position, shown in fig. 3, in which the support 30 makes access to the product easier. In general, in the release position, the container 32 may extend beyond the sleeve 10; while in the retracted position, the container 32 is housed in the sleeve 10, preferably completely housed in the sleeve 10.

In this particular case, the support comprises a base 34, from which a sheath 36 (here tubular) protrudes, the base 34 defining with the sheath 36 a housing capable of housing the container 32. More precisely, the sheath 36 protrudes longitudinally from the base towards the open end 12 of the sleeve 10. As an alternative to being tubular, the sheath 36 may include one or more grips that are capable of mating with the container 32, or may take any other shape configured to removably secure the container 32 to the support 30. In this particular case, the container 32 is force-fitted into the sheath 36, with the container 32 being held in the sheath 36 by friction. The level of friction achieved may be adjusted so that the container 32 may be manually removed from the support 30.

As shown in fig. 2, the support 30 may mate with the cover 38 to enclose the container 32 between the cover 38, the jacket 36, and the base 34. For example, as shown in fig. 2, a cover 38 may be supported on one end of the container 32 and located a distance from the jacket 36. According to another example, the cover 38 may be supported on the free end of the sheath 36 and optionally at a distance from one end of the container 32, so that there is no risk of inadvertently activating a dispensing head that may be provided at the top of the container 32.

In this embodiment, the cover 38 extends the support 30. The cover 38 may be designed to be fully received in the sleeve 10 at least in the retracted position of the support 30. Furthermore, it should be noted that the sheath 36 is completely housed in the sleeve, both in the retracted position of the support (fig. 2) and in the release position (fig. 3).

As noted above, the cover 38 is optional and may not be provided, or may be replaced by other removable or non-removable elements, such as sprayer buttons, decorative elements, etc., which may be associated with the container 32.

Furthermore, the encapsulation device 100 comprises a spring 40, one end of which spring 40 is supported on the support 30, more particularly on the opposite face of the base 34 to the sheath 36. The support 30 is free to rotate about the longitudinal direction X with respect to the spring 40. In this embodiment, the spring 40 is a coil spring, however, other types of springs, or more generally, other types of return systems capable of applying a return force, are contemplated.

Furthermore, the encapsulation device 100 comprises a holding element 50 for holding the support 30 in the retracted position. In this embodiment, the retaining element 50 comprises a split ring (SPLIT RING), however other forms of retaining elements are also contemplated.

In this embodiment, more specifically, the retaining element 50 comprises a portion, called intermediate portion (INTERMEDIATE PORTION) 52, having a notch (notch) 53 configured to cooperate with a corresponding projection 13 of the sleeve 10 (see fig. 2). A portion of the retaining element 50 is thus integrally rotated at least about the longitudinal direction X with respect to the sleeve 10. More generally, other assemblies may be used to integrally rotate the sleeve 10 and the retaining element 50.

Furthermore, the retaining element 50 may also be located between the inner shoulders of the sleeve 10 (see fig. 2), which means that even if a certain clearance is acceptable, its longitudinal translation with respect to the sleeve 10 is substantially prevented.

Side ribs (flank) 54 shaped as annular sections extend on either side of the intermediate portion 52 and extend out of fins (fin) 56 that are narrowed relative to the side ribs 54. The narrowing of the fins 56 may include a reduction in their outer diameter so as to provide a radial space between the fins 56 and the sleeve 10 in which the fins 56 will be able to deform.

Fins 56 face each other on either side of opening 58.

As shown more clearly in fig. 1 and 4, in order to keep the support 30 in the retracted position, the holding element 50 may have at least one stop, in the particular case illustrated three stops 55 being uniformly distributed angularly about the longitudinal direction X. The number and location of the stops 55 may vary. In this particular 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 holding member 50 that are elastically deformable in the lateral direction. Due to their narrowing, the fins 56 can preferentially deform relative to the rest of the retaining element 50.

Thus, in the retracted position, the stop 55 cooperates with the support 30. For example, as previously described, the support 30 may comprise a plurality of hooks 37 distributed annularly and configured to cooperate with the retaining element 50, more particularly with the stop 55, in the retracted position. In the particular case illustrated, each hook 37 protrudes from the support 30, in particular from the base 34, opposite to the sheath 36. Each hook 37 defines a hooking space (hooking space) open towards the holding element 51, and thus here a hooking space open radially outwards. The hooking space defined between the head of the hook 37 and the base 34 from which the hook protrudes can accommodate the stopper 55. Each stop 55 may engage one or more hooks 37, with each stop engaging a plurality of hooks being shown in fig. 4. The laterally extending stop 55 is configured to block longitudinal movement of the support 30 by retaining the hook 37.

Furthermore, the encapsulation device 100 ultimately comprises an actuator 60, the movement of the actuator 60 causing the movement of the support 30 between the retracted position and the release position. In this embodiment, the actuator 60 is tubular about the longitudinal direction X, more specifically, cylindrical with a circular cross section. The actuator 60 has a first end 61 that is open as shown in the upper portion of the figure and a second end 63 that is also open as shown in the lower portion of the figure.

In this embodiment, the actuator 60 is movably mounted in the sleeve 10, in particular rotatably mounted in the sleeve 10 generally about the longitudinal direction X.

The first end 61 may include a recess for inserting a corresponding jamb (jamb) of the ring 62. The ring 62 may be designed to facilitate operation of the actuator 60, as will be seen hereinafter. As an alternative to the interlocking fixation by illustration, the ring 62 may be assembled to the actuator 60 by any suitable interlocking or more mainly by any suitable means (gluing, etc.), in particular so as to be integrally rotatable, or may be integrally formed with the actuator 62. Furthermore, the ring 62 may be radially larger than the actuator 60. The open end 61 or ring 62 extends beyond the sleeve 10 for easy access and manipulation by a user.

Further, a protrusion 66 may be provided on the actuator 60 and protrude in the direction of the sleeve 10, more precisely, to engage in a corresponding groove 16 of the sleeve 10. The protrusions 66 may be provided on tongues of the sleeve 10 to facilitate elastic deformation of the sleeve 10. Thus, insertion of the projection 66 into the slot 16 is easy and accomplished without damage. The slots 16 extend over a limited angular section, for example less than or equal to 90 °, which enables limiting the angular travel (angular stroke) of the actuator 60 with respect to the sleeve 10. Of course, any other way of limiting the angular travel of the actuator 60 relative to the sleeve 10 may be considered to achieve the fact that the actuator 60 and the sleeve 10 engage each other (here, one in the other), thereby limiting the travel of the actuator 60. Furthermore, the number and location of the protrusions 66 and/or corresponding slots 16 may vary.

Furthermore, while positioning of the slot 16 and the projection 66 near the ends 12 and 61, respectively, facilitates assembly of the sleeve 10 to the actuator 60, this is not absolutely necessary and other positions are contemplated.

At the second end 63, the actuator 60 may include a protrusion 65, as more particularly shown in fig. 4, the protrusion 65 being configured to engage in the opening 58 of the retaining element 50. The projection 65 projects longitudinally from the actuator 60 in the direction of the holding element 50.

Further, as shown in fig. 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, a single guide 64 will be described below. It should be understood that the number and arrangement of guides may vary, and that the guides may or may not be identical to each other.

The guide 64 is here designed in the form of a cutout (cutout) of the actuator 60, but it may comprise a channel, a track or the like. The actuator 60 thus forms a second element with a guide 64, the first element (i.e. here the support 30) being engaged with the guide 64. More precisely, the support 30 comprises at least one lug 35, for example as many lugs as there are guides 64 of the actuator. When the support 30 is assembled in the actuator 60, the lugs 35 engage with the guides 64 (here, the lugs 35 engage in the guides 64). The lugs 35 may protrude from the support 30, here from the sheath 36, towards the actuator 60.

The cooperation between the support 30 and the actuator 60 defines the position in which the support 30 can be located relative to the sleeve 10, in particular a retracted position and a release position.

To facilitate insertion of the lug 35 into the guide 64, the guide 64 may be open at one end of the actuator 60, in this particular case at an end 63 opposite the open end 61. Fig. 1 shows an opening 64a of smaller size than the so-called guide 64, but it is also possible to provide an opening 64a of the same size, possibly larger than the opening 64a of the guide 64. However, this is not necessary, and the lugs 35 can also be inserted by benefiting from elastic deformation of the actuator 60 or the support 30.

The assembly of the package device 100 may be accomplished in the following manner. The order of the steps may be modified unless otherwise indicated or limited by the context.

The container 32 is placed in the support 30, in this particular case within the sheath 36. The container 32 may be secured to the support 30 in a reversible manner or an irreversible manner. The actuator 60 is fitted to the support 30 and the lugs 35 are inserted through the open ends of the guides 64, more precisely through the openings 64 a.

The holding member 50 is inserted into the sleeve 10, and the holding member 50 is rotatable integrally with the sleeve 10. The container-support-actuator assembly may be placed in the sleeve 10 with the tab 65 of the actuator 60 cooperating with the opening 58 of the holding element 50 and the hook 37 of the support 30 cooperating with the stop 55 in the holding element 50.

Insertion of the different elements into the sleeve 10 may be achieved by one or the other of the ends 12, 14, typically depending on the shoulder provided inside the sleeve 10. The sequence of steps is adapted to the assembly direction.

The ring 62 is assembled to the actuator 60. In addition, a spring 40 is installed between the support 30 and the base 20, and the base 20 is attached to enclose the package 100. The base 20 may be assembled to the sleeve 10 by a bayonet mount. However, any other component is contemplated.

Spring 40 is an example of a resilient member, or more generally a return system, that is sized to be pre-stressed when it is positioned between support 30 and base 20. More precisely, the spring 40 is pre-stressed when compressed, as it tends to separate the support 30 from the base 20. In this regard, the spring 40 forms a return system configured to move the support 30 to a release position, as will be seen hereinafter. The return system (spring 40) is thus configured to return the support 30 in the first direction, here in the longitudinal direction.

As shown in fig. 2, the actuator 60 may be retained longitudinally in the sleeve 10: at end 61, ring 62 extends radially beyond actuator 60 and beyond the inner diameter of sleeve 10; the sleeve 10 abuts against the holding element 50 at the end 63. In other words, the sleeve 10 is longitudinally held between the ring 62 and the holding element 50; the protrusions 16 also assist in this retention.

The actuator 60 shows a portion accessible to a user, in this particular case the ring 62, when the enclosure 100 is assembled. However, the ring 62 does not allow the user to remove the actuator from the sleeve 10 due to the longitudinal blocking of the projection 16.

In this embodiment, the actuator 60 is fixed against longitudinal translation within the sleeve 10. Furthermore, the actuator 60 can be rotationally displaced within the sleeve 10, in particular around the longitudinal direction X. Here, the actuator 60 may be driven to rotate by a simple action of the user on the ring 62. However, other more complex mechanisms for rotational driving are contemplated.

Fig. 2 shows the enclosure 100 in a retracted position of the support 30. As shown in fig. 4, since the holding element 50 has at least one stop 55, as previously described, the support 30 is held in the retracted position so as to limit the movement of the support 30 under the influence of the restoring force of the spring 40 when the support 30 is in the retracted position. More precisely, the stop 55 is hooked by the hook 37 of the support. Thus, the lugs 35 of the support 30 are in a stable position marked a on the schematic diagram of fig. 5. The support 30 is in the position of fig. 2, for example, with the cover 38 flush with the ring 62.

When the user wants to release the container 32 for dispensing the product, he can drive the ring 62 in rotation. As shown in fig. 5, the guide 64 causes: in the retracted position, the actuator 60 may be driven to rotate equally in one direction or in the opposite direction.

Thus, the user drives the actuator 60, in this particular case rotates, so as to move it along a certain stroke, which can be limited by the projection 66 described previously. At the end of this travel, the lug 35 is in position B (or symmetrical position) of fig. 5, which is a neutral and unstable position. Rotation of the actuator 60 causes rotation of its tab 65, which tab 65 bears against the free end of the fin 56 and pushes it to a point where it elastically deforms, in this case radially outwards. During this process, at least one stop 55 moves laterally (here in a radial plane), after which the stop 55 no longer engages the hook 37: the stopper 55 is thus disabled.

The remaining stops 55 are no longer sufficient to counteract the restoring force of the spring 40 by their number, their position or their resistance. Thus, the retaining element 50 is disabled, which no longer retains the support 30. Under the influence of the restoring force, the support 30 enters the release position shown in fig. 3, the lug 35 being in the stable position C shown in fig. 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 even remove the container 32, such as a lipstick mechanism, and then reinsert it onto the support 30 after use.

During the movement of the support 30 to the release position, the user has typically released the ring 62 so that the actuator 60 is free to rotate relative to the sleeve 10. Due to the elasticity, the holding element 50 tends to resume its shape at rest and thus acts on the projection 65, returning the actuator 60 to its initial position. In parallel, during the longitudinal translation of the support 30, the lugs 35 push against the inclined cam surfaces 67 of the guides 64, which also tend to drive the actuator 60 in rotation and, more generally, tend to return it to its starting position. Thus, the retaining element 50 is configured to automatically reset without actuation of the actuator 60. Of course, the automatic resetting may be obtained solely by the elasticity of the holding element 50, or solely by the cam surface 67 of the guide, or in a different way.

To avoid complete disengagement of the support 30 with respect to the sleeve 10, the movement of the support 30 in the longitudinal direction may be limited by the stop 68 of the guide 60 in a manner opposite to the return force of the spring 40. Furthermore, during the movement of the support into the release position, a click is heard when the lugs 35 abut the stops 68, which gives the user a sensation that the release position has been reached and thus a sensation that the packaging device is correctly operated.

The support 30 is held in the release position under the influence of the restoring force of the spring 40. In this position, the actuator 60 is not movable, because the guide 64 and the lug 35 have substantially complementary shapes in the circumferential direction (actuation direction of the actuator 60) when in the release position (position C in fig. 5).

To move the support 30 from the released position to the retracted position, the user must press the support 30 with a force sufficient to overcome the force exerted by the spring 40. To achieve this, the user may press the cap 38 or reengage the container 32, and the cap 38 or container 32 in turn presses the support 30. In this way, the lugs 35 circulate in the free space of the guides 64 until the hooks 37 of the support 30 cooperate again with the stops 55 of the retaining element 50. Hook 37 may be reengaged with stop 55 by a similar snap fit: the hooks 37 and the fins 56 push against each other to elastically deform, allowing the hooks 37 to pass the stop 55, after which the hooks 37 and the stop 55 return to their rest position, in which the stop 55 resists the movement of the hooks 37 under the influence of the return force of the springs 40. The hook 37 (see fig. 2) and/or the ramp provided on the stop 55 facilitate ratcheting into the retracted position.

When the user releases the pressure at the end of the movement, the spring 40 presses the hook 37 against the stop 55. The click is then heard, which gives the user the sensation that the retracted position has been reached and thus the user the sensation of proper operation of the packaging unit. The lug 35 is then positioned in position a of fig. 5.

In this embodiment, the guide generally has a triangular shape or a substantially triangular shape, as shown in fig. 1 and 5; the apex of the triangle proximate to the stop 68 corresponds to a single position of the actuator 60 relative to the support 30, typically in a released position, while the base of the triangle opposite the apex corresponds to a plurality of possible positions of the actuator 60 relative to the support 30, typically in a retracted position. Cam surface 67 connects the bottom to the apex. The sides of the triangle may be rounded as shown to facilitate quick actuation. Of course other shapes are also contemplated.

If desired, the support 30 may be held in a predetermined orientation relative to the sheath 10, for example by extending the lugs 35 so that they engage in grooves or longitudinal grooves in the sleeve 10. If necessary, decorative hoops (hoop) may be added to cover the longitudinal grooves.

While the present description relates to certain exemplary embodiments, modifications may be applied to these embodiments 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 may be considered:

The lugs 35 may be provided on the actuator 60 and the guides 64 may be provided on the support 30; more generally, all mechanical cooperation may be reversed;

The directions of translation and rotation may be interchanged.
