Description

The invention relates to an application system comprising a lipstick grape which is mounted on a displacement mechanism actuated in rotation between a retracted position and a position of use.

In particular, the lipstick grape is formed with a product for cosmetic use or the like such as a care product for the lips or for another part of the body, said grape being in the form of a solid stick to be applied by friction.

Moreover, there is also a demand for applying such products in a pasty liquid form. To do this, it is known to use a device comprising a container in which the liquid lipstick (or lip gloss in English) is packaged, the application being carried out either by pressing on the flexible container which is then equipped with an applicator, either by immersion of an application brush into the container.

However, such devices have the disadvantage of complicated handling which, moreover, away from the gesture to which users are accustomed to apply a grape lipstick.

In addition, the user must possess and handle two different devices if she wishes to combine the application of a solid lipstick with that of a liquid lipstick, said lipsticks may be of the same or different nature, in particular by their color or their effects. In an attempt to solve this problem, it has been proposed to assemble two standard devices with a connecting piece, without this being satisfactory, particularly from an ergonomic point of view.

The invention aims to improve the prior art by proposing in particular a device for applying a lipstick grape which allows the combined application of a pasty liquid product, while maintaining a gesture of known application.

For this purpose, the invention proposes an application system comprising a lipstick grape which is mounted on a displacement mechanism actuated in rotation between a retracted position and a position of use, said system further comprising a reservoir of pasty liquid product to be applied and a dispensing mechanism for said product which is rotated to pressurize said product into said reservoir, said grape comprising a channel which is in communication with the reservoir on the one hand and with the other on the other. outer surface of said grape so as to allow the application of said product via said grape.

Other objects and advantages of the invention will appear in the description which follows, made with reference to the appended figures, in which:

• the Figures 1 and 2 are longitudinal sectional representations of an application system according to a first embodiment of the invention, respectively in retracted initial position ( figure 1 ) and in the position of use ( figure 2 );
• the Figures 3 and 4 are longitudinal sectional representations of an application device according to a variant of the first embodiment of the invention, respectively in retracted initial position ( figure 3 ) and in the position of use ( figure 4 );
• the Figures 5 and 6 are longitudinal sectional representations of an application system according to a second embodiment of the invention, respectively in retracted initial position ( figure 5 ) and in the position of use ( figure 6 ).

In connection with the figures, there is described an application system comprising a grape R of lipstick formed with a product for cosmetic use or the like such as a care product for the lips or for another part of the body.

The grape R is mounted on a displacement mechanism actuated in rotation between a retracted position ( figures 1 , 3 , 5 ) and a position of use ( figures 2 , 4 , 6 ) to be applied by friction. In the embodiments shown, the application system comprises an outer body 1 in which the grape R is slidably mounted to be respectively retracted into said body in the retracted position and protruding relative to said body in the use position. In addition, the grape R movement mechanism is actuated by a ring 2 rotatably mounted relative to the outer body 1.

The application system further comprises a reservoir of liquid pasty product P to be applied, for example such as a liquid lipstick or a lip care product. According to other embodiments, the system makes it possible to apply a pasty liquid product P to another area of a person, in particular to the skin, or to another type of product, in particular for cosmetic or therapeutic use, or else the application of the product on an object.

The application system also includes a dispensing mechanism of said product which is rotated to pressurize said product into said reservoir. Thus, the application of pasty liquid product P is similar to that of application of grape R lipstick.

Furthermore, to allow the combined application of the grape R and the product P, said grape comprises a channel 3, in particular central through axially said grape, which is in communication on the one hand with the reservoir and on the other hand with the surface outside of said grape so as to allow the application of said product via said grape. In particular, the channel 3 can lead to the beveled area 4 of the grape R which is arranged to facilitate application to the lips, without changing the geometry of said area relative to a conventional grape.

At the outlet of channel 3, the liquid product P spreads on the beveled zone 4 so that the grape R also forms an applicator for said product. Thus, the user can apply the grape R alone or the product P together with said grape R. In addition, by acting on the hardness of the grape R, it is conceivable that the system allows the only application of the product P by moderate friction, the grape R then forming only application support. The application of grapes R or said grape and the product P being then made by greater friction.

The pasty liquid product P may be of the same nature as the product forming the grape R. It may also be of a different nature, for example in its color or in its aesthetic and / or therapeutic effects. In addition, the pasty liquid product P may be chosen to provide an effect which combines with that of the product forming the grape R.

In the embodiments shown, the moving mechanism comprises a bucket 5 on which the grape is mounted, said bucket being provided with a central orifice 6 through which the reservoir is in communication with the channel 3. In embodiments shown, the opening 6 of the bucket 5 is surmounted by a chimney 7 around which the grape R is mounted, the channel 3 being disposed in the axial extension of said chimney.

In relation to Figures 1 to 4 a first embodiment of an application system is described below in which the actuating ring 2 of the moving mechanism also forms means for actuating the dispensing mechanism.

The system comprises a lower actuating body 8 which is rotatably mounted on an upper body 9, said bodies being made of rigid material including plastic or metal. In addition, the grape R is integral with the upper body 9 in which the reservoir is housed. More specifically, the bucket 5 is disposed on the upper wall of the upper body 9 while being attached to an opening in said wall ( figures 1-2 ) is formed in one piece with said wall ( Figures 3-4 ).

The product dispensing mechanism P is actuated by rotating the lower body 8 in one direction. To do this, in the embodiment shown, the lower body 8 is clipped into the upper body 9 to allow the relative rotation of the two bodies 8, 9.

The upper body 9 is mounted in reversible translation in the outer body 1 between the retracted position and the use position of the grape R. The system also comprises a protective cover 10 which is mounted around the outer body 1 to cover the upper wall of the upper body 9. For aesthetic reasons, the cap 10 may be provided transparent or at least translucent to leave apparent the grape R.

In addition, the lower body 8 is mounted in translation in the ring 2 to reversibly move the upper body 9 between its two positions by rotation of the ring 2 respectively in one direction, and to be rotated by said ring when the grape is in position of use.

In the embodiment shown, the inner surface of the ring 2 comprises a helical groove 11, the lower body 8 comprising an outer lug 12 which is engaged in said groove on the translational stroke. In addition, the lug 12 may come into axial abutment at the end of the groove 11 when the grape R is in the position of use, so as to allow the rotational drive of the lower body 8 via the ring 2.

Furthermore, the inner surface of the outer body 1 comprises an axial groove 13 in which an outer lug 14 of the upper body 9 is guided. The lug 14 may be in axial abutment in the groove 13 when the grape R is in the position of use, so as to allow the rotational drive of the lower body 8 via the ring 2. In the embodiment shown, two sets of lugs 14 - groove 13 are provided on either side of the axis of translation.

Thus, the rotation of the ring 2 successively causes the rise of the grape R in use position and then, if the joint application is desired, the actuation of the distribution mechanism by rotating the lower body 8. After application, the user turns ring 2 in direction reverse to retract the grape R in the outer body 1, the actuation of the dispensing mechanism remaining inactive.

To do this, the dispensing mechanism may comprise a non-return rotation device through which the lower body 8 is mounted on the upper body 9 to prevent the rotation of said lower body in the opposite direction to the actuation . Indeed, in the embodiment shown, the distribution of the product P means cumulative rotations of the lower body 8 in one direction as and applications.

According to a first variant of the first embodiment ( Figures 1 and 2 ), the system comprises a pocket 15 flexible and sealed, for example made of elastomeric material, forming a reservoir in which the product P to be applied is packaged. The pocket 15 shown is formed of a tubular sleeve having a lower opening and an upper opening.

The pocket 15 is housed in the lower body 8 and upper 9 to protect it. In addition, the pocket 15 is integral in rotation with the lower body 8 and is integral with the grape R in sealed communication with the channel 3. On the Figures 1 and 2 , the upper opening of the pocket 15 is mounted around the bucket 5 to be interposed in a sealed manner between said bucket and a housing of the upper wall in which it is fitted.

During the rotational actuation of the lower body 8, it rotates the flexible bag 15 which is secured elsewhere R raisin raises. This therefore results in a twisting of the flexible pouch 15, and therefore a decrease in the packaging volume of the product P. The product P is then pressurized in the bag 15, said pressure inducing a distribution of the product P through the channel 3 .

Furthermore, the lower body 8 comprises a bore on which the lower opening of the pocket 15 is mounted, a lower closure means of the flexible pouch 15 being associated in said bore. More specifically, the bore has an axial annular wall against which the outer surface of the lower opening is disposed, the sealing means sealingly sealing said surface against said wall.

The sealing means shown is formed of a ball 16, for example glass to be transparent or at least translucent so as to leave at least the color of the product P visible through it, said ball being mounted in the bore after the packaging of the product P in the bag 15. As a variant not shown, a closure cap may be used, or the molding of a sealing wax may be formed in the bore after conditioning the product P.

According to a second variant of the first embodiment ( Figures 3 and 4 ), the dispensing mechanism comprises a piston 17 disposed in a space of the upper body 9 forming a reservoir. In particular, as shown, the reservoir may be constituted by the interior volume of the upper body 9.

The piston 17 is mounted along a rack 30 to rotate the lower body 8 by rotating the relative movement of said rack with respect to said piston in translational movement of said piston so as to compress the product P towards the channel 3.

On the Figures 3 and 4 , the rack 30 is arranged axially with its lower portion rotatably connected to the lower body 8, said rack being in the form of a rod whose periphery has an external thread.

A threaded bore of the piston 17 is mounted on said rod to be displaceable in translation between a lower position close to the lower body 8 ( figure 3 and 4 ) for the first applications, and a higher position in the vicinity of the grape R for the latest applications. Thus, the successive displacements of the piston 17 between these two positions make it possible to push the product P conditioned through the channel 3, by successive manual rotation of the lower body 8.

In relation to Figures 5 and 6 a second embodiment of an application system is described below in which the dispensing mechanism is actuated by a second ring 18 which is rotatably mounted relative to the outer body 1, each ring 2, 18 being arranged to independently operate the corresponding mechanisms. Thus, the user can operate the joint application regardless of the position of the grape R.

In the figures, the ring 2 is rotatably mounted around the second ring 18, the actuating zone of said second ring being disposed under said ring. To do this, the second ring 18 comprises an upper sheath 19 in which the reservoir 20 is housed being driven in translation together with grape R.

In particular, the reservoir 20 comprises an upper tube 21 which is fitted in a sealed manner on the grape R movement mechanism, said tube being in communication with the channel 3 of said grape. More specifically, the orifice 6 of the bucket 5 is extended downwards by a chimney 22 around which the upper tube 21 is fitted, said fitting being arranged to secure the reservoir 20 to the bucket 5.

The dispensing mechanism comprises a compression piston 23, said piston being displaced relative to the reservoir 20 by rotation of the second ring 18. The piston 23 is mounted on the reservoir 20 opposite the upper tube 21, leaving an opening filling station which is sealingly closed by a stopper 24.

The piston 23 shown comprises an outer wall 25 which is mounted in the sheath 19, the inner periphery of said sheath having a polygonal section which is arranged to combine an axial sliding of the bearing surface 25 on said periphery with a rotational drive of said span. by said periphery. Thus, by rotating the ring 2, the reservoir 20 - piston assembly 23 moves together without compression of the product P and, by rotation of the second ring 18, the piston 23 is driven over its compression stroke of said product.

In this second embodiment, the displacement mechanism comprises a sheath 26 actuated in rotation by the ring 2, said sheath being rotatably mounted relative to a spiral 27 having an inner helical groove in which at least one pin is engaged. bucket 5, so as to transform a rotational movement of said sheath in vertical displacement of said bucket. More specifically, two pins 28 are diametrically formed on the outer surface of the cup 5 and the spiral 27 is housed in the outer body 1 on which the sheath 26 is rotatably mounted.
