Description

Support system for a cosmetic pencil

The present invention relates to a support system for a cosmetic pencil.

In general, support systems for a cosmetic pencil include an interior assembly and a support device including a support surface intended to be gripped by a user. The support devices are further configured to receive the interior assembly.

The interior assembly typically includes a tubular device, a receiving device configured to receive the cosmetic pencil and a guide device. The guide device is configured to convert a rotation, for example caused by the user, into a translation of the receiving device relative with respect to the guide device for removing the cosmetic pencil.

The support device typically comprises prestigious materials and / or decorations making it possible to improve the experience and the comfort of the user when applying the cosmetic pencil inserted into the support system. In particular, the support surface of the support device is adapted to allow simple gripping of the surface by the user.

In such support systems, the user could purchase only the interior assembly, without the support device. When the interior assembly is not inserted in the support device, it is possible to actuate the guide device. For example, the user is likely to grasp a surface of the guide device projecting from the tubular device to take out or return the cosmetic pencil.

Thus, the user is likely to use the interior assembly in the absence of the support device, which can result in a poor user experience. The surface of the guiding device of such support systems is ill-suited to be grasped by the user, for example because of the materials used, less quality surface machining or an unsuitable shape.

An object of the invention is thus to have a support system having a better user experience and improved comfort.

To this end, the invention relates to a support system for a cosmetic pencil, comprising a tubular device having a helical groove with a longitudinal central axis, a device for receiving the cosmetic pencil comprising at least one lug, disposed inside the tubular device, the receiving device being movable in translation relative to the tubular device along the longitudinal axis, a guide device interposed radially between the receiving device and the tubular device and having a slot extending over most of the longitudinal height of the guide device, the lug being engaged in the groove through the slot, the guide device being movable in rotation about the longitudinal axis relative to the tubular device, the guide device comprising, in a longitudinal direction, a first end and a second open end for the exit of the cosmetic pencil, a support device placed around the tubular device and a connection linking the support device to the device guide in rotation about the longitudinal axis, the support device comprising at least a first support surface for a user, the tubular device extending longitudinally beyond the first end of the guide device, such so that any plane extending perpendicular to the longitudinal axis and intersecting the first end of the guide device cuts equally the tubular device.

The fact that the tubular device extends longitudinally beyond the first end of the guide device, so that any plane extending perpendicular to the longitudinal axis and intersecting the first end of the guide device also cuts the device tubular, makes the use of the support system in the absence of the support device very complicated, even impossible. Indeed, the user cannot grasp a surface of the guide device extending parallel to the longitudinal axis, because the tubular device according to the invention makes such surfaces of the guide device inaccessible.

One possibility for rotating the guide device according to the invention in the absence of the support device is to grasp the guide device on a surface extending perpendicular to the longitudinal axis. However, it is very complicated for the user to grab such a surface and create a rotation.

An interior assembly comprising the tubular device, the receiving device and the guide device is thus dependent on the device of the support device. Use of the interior assembly in the absence of the support device is avoided. The support system according to the invention can therefore only be used in the presence of the support device having a support surface suitable for the user.

As a result, the support system presents a better user experience and improved comfort.

The support system may also have one or more of the characteristics below, considered individually or in any technically possible combination:

- The first end of the guide device is an end for driving in rotation the guide device linked in rotation to the support device. - The tubular device comprises a first layer and a second layer extending radially inwards from the first layer relative to the longitudinal axis, the first layer preferably comprising a material distinct from a material of the second layer.

- The first layer includes at least a second support surface for the user.

- The support system includes a reversible fixing blocking the support device and the guide device longitudinally in position relative to each other.

- The fastening is chosen from the following list: a snap connection, a magnetic connection, a bayonet connection.

- The link between the support device and the guiding device in rotation around the longitudinal axis is chosen from the following list:

+ at least one longitudinal finger carried by one of the support device and of the guide device, engaged in at least one housing formed in the other of the support device and of the guide device;

+ at least one longitudinal rib carried by one of the support device and the guide device, cooperating with at least one longitudinal groove formed on the other of the support device and the guide device;

+ a link by cooperation of forms;

+ a bayonet link.

- The tubular device has an open lower longitudinal end extending around the first end of the guide device, the support device comprising a central protuberance engaged in the lower longitudinal end and carrying the connection in rotation with the guide device .

- The central protuberance also carries the reversible fixing blocking the support device and the guide device longitudinally in position relative to one another.

The first end 13 of the guide device 8 is an end for driving in rotation the guide device 8 linked in rotation to the support device 4.

The guide device 8 has a slot 16 through which the lug 12 passes. The slot 16 extends over most of a longitudinal height H of the guide device 8. The longitudinal height H is the height of the guide device 8 in the longitudinal direction. By “most of the longitudinal height” is meant at least 51% of the height H, preferably at least 80% of the height H. As can be seen in FIG. 1, the slot 16 comprises at least on one of its ends a notch 17 configured to stop the receiving device 6 and thus the cosmetic pencil in an extended position.

In addition, the guide device 8 comprises a stop 18 configured to come into contact with the tubular device 10 to fix the guide device 8 relative to the tubular device 10 in the longitudinal direction.

The lower longitudinal end 20 extends in particular towards the outside of the first end 13 relative to the longitudinal axis L.

As visible in the example shown in FIG. 1, the tubular device 10 extends longitudinally beyond the first end 13 of the guide device 8. Any plane extending perpendicular to the longitudinal axis L and intersecting the first end 13 of the guide device 8 also cuts the tubular device 10. An example of such a plane P is shown in FIG. 1.

The first end 13 is in particular inaccessible, from the outside, in a direction perpendicular to the longitudinal direction. In the absence of the support device 4, for example, only the tubular device 10 is accessible in a direction perpendicular to the longitudinal axis L.

The tubular device 10 has a helical groove 21 with a longitudinal central axis L receiving one end of the lug 12.

According to another example, the first layer 22 and the second layer 24 each comprise a polymeric material. The first layer 22 is notably accessible from the outside for a user in a direction perpendicular to the longitudinal direction. For example, the first layer 22 includes a support surface 26 for the user.

The support device 4 is placed around the tubular device 10. The support device 4 has a section, for example substantially forming a "U" in a plane comprising the longitudinal axis L, defining a receiving space for part of the interior assembly 2.

The support device 4 notably comprises at least one layer. Advantageously, the support device 4 comprises a first layer 27 and a second layer 28 distinct from the first layer 27 and extending in particular towards the inside of the first layer 27 relative to the longitudinal axis L.

For example, the first layer 27 comprises a different material compared to a material of the second layer 28. The first layer 27 comprises in particular a prestigious material, such as zamac, stainless steel, aluminum, a polymer, paper, cardboard, ceramic and / or wood. The support device 4, and in particular the first layer 27, comprises an external support surface 29 having for example a rectangular geometry in a plane perpendicular to the longitudinal axis L.

According to a variant, not shown, the support device 4 comprises a single layer. According to another variant, not shown, the support device comprises at least three layers.

The support device 4 and the guide device 8 are linked together by a rotational connection 32 around the longitudinal axis L. The rotational connection 32 is configured to transmit a torque between the support device 4 and the guide device 8. In particular, when the user applies a rotation to the support device 4, a torque is transmitted by the rotating link 32. Several examples of rotating links 32 are visible in FIGS. 1 to 1 1 and will be described below.

The support system 1 further comprises a cover 40 defining an interior space, the cover 40 being configured to receive at least part of the tubular device 10 in its interior space. According to the examples of the figures, the cover 40 defines in the closed position with the support device 4 a closed space comprising the interior assembly 2.

The support system 1 further comprises a reversible attachment 42 longitudinally locking in position the support device 4 and the guide device 8 relative to each other. By "reversible", it is understood that the attachment 42 is configured to temporarily fix the support device 4 and the guide device 8 relative to one another. For example, during an exchange of the interior assembly 2, the user can detach the interior assembly 2 from the support device 4 and for example insert a new interior assembly 2.

According to the first embodiment, shown in Figure 1, the attachment 42 is a bayonet connection. By "bayonet connection" is meant here a connection comprising a lug having a head and a receiving notch configured to receive the lug. To fix the lug, a push-turn movement is carried out. The head retains the lug longitudinally in the notch.
