Description

Title of the invention: Device for packaging a product such as a cosmetic product Technical field

[0001] The present 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 transport, for example in a bag or handbag, 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 provides satisfaction, 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. Statement of the invention

[0004] To this end, the present disclosure 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 being driven in rotation along a nominal stroke to cause the movement of the support, a return system configured to return the support to the release position and a stop provided so as to limit the stroke of the actuator relative to the nominal stroke when the support is in the release position.

[0005] The support may carry the product or an intermediate container containing the product, such as a reservoir, whether or not equipped with a dispensing, vaporization, etc. mechanism.

[0006] The movement of the actuator along the nominal stroke causes the support to move at least from the retracted position to the disengaged position. The return system, which returns the support to the disengaged position, can assist the transition of the support to the disengaged position. Furthermore, in the disengaged position, a stop limits the stroke of the actuator relative to the nominal stroke, so that the support cannot inadvertently return to the retracted position. In other words, in the disengaged position, the possible stroke of the actuator is less than in the retracted position, because of the stop.

[0007] Furthermore, since the actuator is configured to be driven in rotation, the actuation gesture is particularly pleasant for the user and untimely actuations are limited.

[0008] When the support is in the disengaged position, it is subjected to the force exerted by the return system, which tends to maintain it in the disengaged 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 a position allowing movement of the actuator over its entire nominal stroke and, ultimately, to return the support to the retracted position.

[0009] The return system may comprise any element exerting a return force, for example an element exerting an elastic return force, such as an elastomer or a spring, or an element exerting a magnetic return force, such as a magnet. The return force may be attractive or repulsive.

[0010] Thanks to the cooperation between the actuator, the stop and the return system, the packaging device allows a simple gesture for dispensing the product, while providing good maintenance of the product support in the release position. In addition, this maintenance is based on a mechanical stop, which can be implemented reliably 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 maintenance in the release position is ensured in part by the stop. As a result, the environmental impact of the packaging device is much improved.

[0011] In some embodiments, the return system is configured to return the support to the release position in a first direction and the actuator is configured to be rotated in a second direction different from the first direction, preferably orthogonal to the first direction. The stop can therefore limit the movement of the actuator in the second direction without hindering the movement of the support in the first direction.

[0012] In some embodiments, said stop forms a second stop and the The packaging device further comprises a first stop provided so as to limit the movement of the support under the effect of the return system when the support is in the retracted position. In these embodiments, in the retracted position, the first stop limits the movement of the support under the effect of the return system, so that the support remains in the retracted position. By moving the actuator according to its nominal stroke, it is possible to clear the first stop so as to no longer block the return system; the return system can then drive the support towards the release position. Thanks to the first stop, the support is effectively retained in the retracted position.

[0013] In some embodiments, said return system forms a first return system, and the packaging device further comprises a second return system configured to return the support to the retracted position. Thus, while the first return system assists the movement of the support to the release position, the second return system assists the movement of the support to the retracted position. Moving the support is therefore easy for the user. In addition, the second return system helps to maintain the support in the retracted position, which limits the unintentional release of the support.

[0014] In some embodiments, the second return system is configured to return the support in a different direction from the first return system. Two different directions means two directions that form a non-zero angle between them, and not just two opposite directions of the same direction. Thus, the return systems exert little or no concurrent action, which facilitates the movement of the support between the release position and the retracted position. Where appropriate, the first (respectively second) return system is configured to return the support in a direction in which it is potentially blocked by the first (respectively second) stop.

[0015] In certain embodiments, the return force exerted by the first return system is greater than or equal to the return force exerted by the second return system. The return force exerted by one or other of the systems being potentially scalable, this condition is verified at least in the states in which the support is likely to move towards one or other of the retracted position and the release position. Thus, it is provided that the support is preferentially returned towards the release position, in order to ensure good accessibility of the product for the user.

[0016] In some embodiments, the first return system and the second return system are formed by the same prestressed elastic component. Thus, the return systems are particularly simple and inexpensive. For example, the same elastic component can be prestressed in one direction to form the first recall system, and in another direction to form the second recall system. In other embodiments, the first recall system and the second recall system may be formed by different components, independent of each other.

[0017] In some embodiments, the support is longitudinally movable in the sheath.

[0018] In some embodiments, the orientation of the support relative to the sheath is maintained between the retracted position and the release position. The device is therefore more practical to use. In addition, in the case of corresponding decorations on the sheath and the support, this allows better control of the aesthetic appearance of the packaging device.

[0019] In some embodiments, a first member of the support and the actuator engages with a guide of a second member of the support and the actuator. The support and the actuator cooperate such that movement of the actuator, particularly rotational movement, causes, as previously discussed, movement of the support. The first member may include a follower member that engages with and follows the guide, for example in the form of a protrusion, a slot, a pin, etc. Other types of cooperation are also contemplated.

[0020] In certain embodiments, the guide has a first portion corresponding to the nominal stroke of the actuator and a second portion, connected to the first portion, corresponding to the movement of the support relative to the sheath under the effect of the return system. Thus, the guide is traveled in its first portion thanks to the movement of the actuator, and in the second portion thanks to the (first) return system. Where appropriate, the second return system can influence, for its part, the movement of the support in the first portion.

[0021] In some embodiments, the guide is generally L-shaped. The branches of the L may form an angle of between 45° and 135°.

[0022] In some embodiments, the packaging device further comprises a product container provided on the support. The container may be removable from the support, the packaging device then functioning as a storage case, possibly refillable and usable with different products.

[0023] 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

[0029] Figures 1 to 4 illustrate a packaging device 100 according to one embodiment.

[0030] 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 (hereinafter “longitudinal direction X”). 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.

[0031] 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.

[0032] The sheath 10 is here of circular section.

[0033] 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.

[0034] As is apparent from [Fig.l] in particular, the sheath 10 has a slot 16. The slot 16 may open onto one end of the sheath 10, in this case onto the end 14 opposite the open end 12. The slot 16 extends here in a first direction, namely the longitudinal direction, but other directions are envisaged. The slot 16 is here rectilinear.

[0035] As shown in [Fig.2], the sheath 10 actually comprises, in this embodiment, two diametrically opposed slots 16. The number and arrangement of the 16 slots may vary.

[0036] 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 necessary and as illustrated in the figures, the product may be provided in an ad hoc container 32, possibly provided with dispensing means (pump, cam, spray, etc., not illustrated in the figures). Alternatively, the product may 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 rechargeable.

[0037] 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 [Fig. 2], in which the product is normally not accessible, and a release position, illustrated in [Fig. 3], in which the support 30 facilitates access to the product. Typically, in the release 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.

[0038] 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.

[0039] The support 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. 2]. For example, the cap 38 may 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. According to another example, the cap 38 can rest on one end of the container 32 and optionally be located at a distance from the jacket 36.

[0040] 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 ([Fig.2]) and in the released position ([Fig.3]).

[0041] 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.

[0042] The support 30, and more particularly its base 34, may define a groove 37, here between two protuberances 37a which project from the base 34 in a direction opposite to the container 32. The groove 37 makes it possible to secure, in rotation around the axis X, the support 30 with a first end of a spring 40. To do this, said first end, referenced 42 in [Fig.l], may have a shape complementary to that of the groove 37 in the direction of rotation. In this case, the first end 42 of the spring 40 comprises a rectilinear portion, so as to distribute the rotational torque over a larger part of the protuberances 37a and thus make the rotational securing between the first end 42 of the spring 40 and the support 30 more reliable.

[0043] Of course, other means can be implemented to secure the support 30 in rotation with the first end 42 of the spring 40.

[0044] In this embodiment, the spring 40 is a helical spring, however other types of springs are contemplated. The first end 42 extends radially inwardly of the spring 40.

[0045] The second end 44 of the spring 40 may have a shape similar to the first end 42, as illustrated, or a different shape. The second end 44 is, for its part, integral in rotation with an insert 50. To do this, the second end 44 may be received in a groove 52 of the insert 50 similar to the groove 37 of the support 30. However, other means of rotational securing are envisaged as a replacement for the groove(s) 37, 50, for example one or more openings or any other at least partial complementarity of shapes.

[0046] The packaging device 100 finally comprises an actuator 60 whose movement, and more particularly the rotational drive, causes the support 30 to move between the retracted position and the release position.

[0047] In this embodiment, the actuator 60 is tubular around the longitudinal direction X, more particularly cylindrical with a circular section. The actuator 60 has an end 61, illustrated in the upper part in the figures, which is open, and an end 63, illustrated in the lower part in the figures, which is intended to be closed by the insert 50. In this embodiment, the insert 50 is assembled longitudinally to the actuator 60 by a collar 54, which projects from the insert 50 and is housed in a corresponding groove of the actuator 60. Here, the collar 54 is continuous circumferentially, but it could not be. More generally, other assemblies would be possible to longitudinally secure the actuator 60 and the insert 50.

[0048] Furthermore, the actuator 60 and the insert 50 are integral in rotation about the axis X. To do this, it is possible to provide at least one notch 56 on the insert 50, here two diametrically opposed notches 56, intended to engage in a corresponding withdrawal of the actuator 60. The notches 56 are spaced from each other in the circumferential direction. However, other assemblies would be possible to secure the actuator 60 and the insert 50 in rotation.

[0049] Thus, the insert 50 is integral in rotation and in translation with the actuator 60.

[0050] Furthermore, the actuator 60 may comprise a ring 62 at its open end 61, to facilitate its handling, as will be seen later. The ring 62 may be assembled to the actuator 60, in particular made integral in rotation, by any suitable means (gluing, interlocking, etc.), or even be made integral with the actuator 62. 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 or the hoop 18 (mentioned below) to be accessible and handled by the user.

[0051] As shown in Figures 1 and 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 rib, 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 60 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. As is clear from [Fig. 2], the lug 35 is sufficiently protruding to exceed the actuator 60 and also engage in the slot 16 of the sheath 10 when the actuator 60 and the support 30 are, in turn, fitted in sheath 10.

[0053] The cooperation between the support 30, the actuator 60 and the sheath 10 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. 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 of the support 30.

[0055] The packaging device 100 can be mounted 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 jacket 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 open end of the guide 64. The spring 40 is installed, its end 42 engaging with the support 30. The other end 44 of the spring 40 is engaged with the insert 50, then the insert 50 is assembled to the actuator 60, for example by means of the collar 54 previously described.

[0057] 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 insert 50. More precisely, the spring 40 is prestressed in compression, in the sense that it tends to move the support 30 away from the insert 50. In this, the spring 40 forms a first return system configured to return the support 30 to the release position, as will be seen later. The first return system (the compressed spring 40) is therefore configured to return the support 30 in a first direction, namely here the longitudinal direction.

[0058] Furthermore, the ends 42, 44 of the spring 40 being integral in rotation with the support 30 and the insert 50 respectively, it is possible to prestress the spring 40 also in torsion. In this, the spring 40 forms a second return system configured to return the support 30 to the retracted position, as will be seen later. The second return system (the spring 40 in torsion) is configured to return the support 30 in a second direction, namely here the circumferential direction.

[0059] Consequently, the same elastic component, namely here the spring 40, can be prestressed differently in two different directions so as to form two return systems configured to return the support in different directions.

[0060] The assembly of the packaging device 100 can continue by fitting the sheath 10 around the actuator 60. A hoop 18, possibly decorative, can be mounted around the sheath 10. In this embodiment, the hoop 18 protrudes from the sheath 10 on the side of the end 14 opposite the open end 12. In particular, the hoop 18 can cover the slot 16. The hoop 18 makes it possible to assemble the base 20 to the sheath 10, which completes the closing of the end 14 of the sheath 10 and masks the insert 50. According to a variant, the base 20 could be assembled directly to the sheath 10. In any event, the base 20 is decorative and plays no role in the movement of the support 30. The base 20 could also be made of the same material as the hoop 18.

[0061] As can be seen from [Fig. 2], the actuator 60 can be held longitudinally in the sheath 10: at the end 61, the ring 62 extends radially beyond the actuator 60, and exceeds the inner diameter of the sheath 10; at the end 63, the insert 50 extends radially beyond the actuator 60, and exceeds the inner diameter of the sheath 10. In other words, the sheath 10 is held longitudinally between the ring 62 and the insert 50.

[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 insert 50.

[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] The conditioning device 100 is therefore such that the (first) return system, i.e. here the compressed spring 40, is configured to return the support 30 to the release position in a first direction, namely here the longitudinal direction, and the actuator 60 is configured to be moved in a second direction, in this case the circumferential direction, different from the first direction. In this case, the second direction, circumferential, and the first direction, longitudinal, are even orthogonal to each other.

[0065] [Fig. 2] illustrates the conditioning device 100 in the retracted position of the support 30. As illustrated in [Fig. 4], which represents a detail of [Fig. 1], the support 30 is held in the retracted position thanks to the fact that the conditioning device, here the actuator 60 and more particularly the guide 64, has a first stop 65 provided so as to limit the movement of the support 30 under the effect of the (first) return system when the support 30 is in the retracted position. More precisely, the lug 35 of the support 30 is in the position referenced A on [Fig.4], and the spring 40, compressed, pushes the lug 35 towards the first stop 65. Due to the presence of this stop 65, the support 30 can no longer come out of the sheath 10, and it is in the position of [Fig.2] where, for example, the cap 38 is level with the ring 62.

[0066] When the user wishes to release the container 32 for the purpose of dispensing product, he can rotate the ring 62. A third stop 67, against which the lug 35 rests in position A (retracted position of the support), limits the direction of rotation of the actuator 60.

[0067] The user therefore drives the actuator 60, in this case in rotation, in order to move it along a stroke called the nominal stroke. This nominal stroke, which will ultimately cause the support 30 to move towards the release position, corresponds to a first portion 64a of the guide 60. The first portion 64a extends mainly in the circumferential direction, or more generally in the second direction mentioned above. Optionally, a return 65a may be provided in the extension of the first stop 65 to prevent the support 30 from coming out of the retracted position in an untimely manner; the user's driving force must then make it possible to overcome this return 65a so that the nominal stroke is traveled.

[0068] At the end of the nominal stroke (to the left in [Fig. 4]), the shape of the guide 64 is such that the first stop 65 no longer opposes the movement of the support 30 under the effect of the return force in the longitudinal direction. Under these conditions, the first return system (compressed spring 40) moves the support 30 towards the release position. The support 30 is then in the release position illustrated in [Fig. 3], and the lug 35 is in position B illustrated in [Fig. 4]. 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 having used it.

[0069] For the transition to the release position, the lug 35 travels a second portion 64b of the guide 64, the second portion 64b being connected to the first portion 64a and corresponding to the movement of the support 30 in the sheath 10 under the effect of the (first) return system. The second portion 64b extends mainly in the longitudinal direction, or more generally in the first direction mentioned above.

[0070] 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 fourth stop 68, opposing the return force of the first return system (compressed spring 40). In addition, when the lug 35 is pressed against the fourth 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 achieved, and therefore the feeling of good functioning of the conditioning device.

[0071] The support 30 is held in the disengaged position due to the fact that the conditioning device, here the actuator 60 and more particularly the guide 64, has a second stop 66 configured to limit the travel of the actuator 60 relative to the nominal travel when the support 30 is in the disengaged position. Indeed, as illustrated in [Fig. 4], when the lug 35 is in position B, the actuator 60 cannot be rotated according to its nominal travel (to the right, in [Fig. 4]), because it would hit the second stop 66. It is therefore impossible to store the support 30 in the retracted position by simply moving the actuator 60.

[0072] 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 first return system. 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, if necessary via the sleeve 36. In doing so, the lug 35 travels along the second portion 64b of the guide in the other direction (downwards in [Fig. 4]), until the second stop 66 no longer opposes actuation of the actuator 60. For example, the user can push the support 30 to the boundary between the second portion 64b and the first portion 64a.

[0073] The shape of the guide 64 may be designed to facilitate the transition between the first portion 64a and the second portion 64b, as illustrated in [Fig. 4]. For example, an intermediate portion of the guide may extend in an intermediate direction between the first direction and the second direction.

[0074] Once the support 30, more particularly the lug 35, has reached the transition between the second portion 64b and the first portion 64a, the return of the support 30 to the retracted position can be facilitated by the second return system, namely the torsion spring 40. Indeed, the torsion of the spring 40 has been increased in one direction by the actuation of the actuator 60 to release the support 30 from the retracted position. This torsion, which is no longer overcome by the user holding the actuator 60, is exerted here in the other direction to return the support 30 to the retracted position, and in particular to automatically reset the actuator 60 via the engagement of the spring 40 with the insert 50. It follows that the lug 35 returns to the position A of [Fig. 4].When the lug 35 is pressed against the third stop 67 under the effect of the second return system, a clicking noise is heard, which gives the user the feeling that the retracted position has been reached, and therefore the feeling that the packaging device is working correctly.

[0075] The assistance of the second return system for returning to the retracted position also makes it possible to reduce the play necessary, in the guide 64, to ensure good return to the retracted position. The movements required by the user are therefore of lesser amplitude than in the state of the art, which makes them more pleasant while being at least as reliable.

[0076] In the present embodiment, the guide is generally L-shaped as can be seen in [Fig. 4]. The branches of the L can form, respectively, the first portion 64a and the second portion 64b. Other shapes are of course conceivable. For example, the guide 64 could have a half-moon shape. The guide 64 optionally includes, as illustrated in [Fig. 4], rounded portions to facilitate rapid actuations.

[0077] Optionally, at least at the points where the movement of the support is not limited by either the first stop 65 or the second stop 66, the return force exerted by the first return system (compressed spring 40) is greater than or equal to the return force exerted by the second return system (torsional spring 40). This makes it possible to favor the transition to the disengaged position over the transition to the retracted position, given that the force of the first return system can be more easily overcome by the user, by means of a simple pressure.

[0078] As seen previously, the lug 35 of the support engages in the slot 16 of the sheath 10, which secures the support 30 in rotation relative to the sheath 10. It follows that the orientation of the support 30 relative to the sheath 10 is maintained between the retracted position and the disengaged position. Only the actuator 60 is here movable in rotation relative to the support 30 and to the sheath 10.

[0079] 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 actuator 60 may be provided outside the sheath 10 rather than inside; - the guide 64 can be provided in the sheath 10 and the slot 16 in the actuator 60. In this case, the support 30 would be integral in rotation with the actuator 60 and would rotate in the sheath 10 between the retracted position and the disengaged position; - the lug 35 could be provided on the sheath 10 and the slot 16 on the support 30; more generally, all the mechanical cooperations could be reversed; - translation and rotation directions could be exchanged.

[0080] 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.
