Description:
Dispensing head for a cosmetic product, associated device and associated application method

The present invention relates to a dispensing head for a cosmetic product comprising:

- a base designed to be mounted on a neck of a receptacle,

- a dispensing tube projecting from the base up to a free end, the dispensing tube defining a central product dispensing passage opening up at the free end,

- an applicator engaged around the dispensing tube, the applicator defining a through opening in which the tube fits.

Such a device is intended particularly for application of a cosmetic care product, a makeup product and/or a coloring product on a user’s body surface.

A cosmetic product is more generally a product as defined in EC Regulation number 1223/2009 of the European Parliament and the Council of November 30, 2009, relating to cosmetic products.

Makeup routines tend to become more complex and to be composed of several steps, for example to apply the product precisely, then to rub the body surface and/or to comb keratinic fibers, etc..

Such routines require that users should have different tools for each operation. This increase in the number of tools requires a non-negligible volume and cost for users. Furthermore, the different tools are often accompanied by an increased number of small elements such as caps, increasing usage complexity and therefore creating a loss of time for the user.

In patent application FR 2 747 650 A1 , a dispensing capsule for a receptacle comprises a cap fixed in translation relative to the receptacle and a tube that can be extended relative to the cap.

However, such a capsule is not fully satisfactory for making a complex product application routine. In particular, the user still needs to possess several tools to perform the different steps in the routine.

In patent application WO 2014/024040 A2, a sliding double applicator combines a mascara brush and a crayon for the eyes in a single device.

One purpose of the invention is to provide a dispensing head for a cosmetic product that is multi-functional for performing complex routines, while remaining ergonomic and easy to use.

To achieve this, the object of the invention is a dispensing head for a cosmetic product of the type mentioned above, characterized in that the applicator is movable in axial translation relative to the tube and the base between a retracted position in which the free end of the tube projects outside the applicator, and an extended position in which the free end of the tube is flush with the outlet from the opening of the applicator or fits inside the opening of the applicator.

Since the applicator is able to occupy a retracted position, the tube is in the clear when a cosmetic product is dispensed through the central passage. Therefore application of the product is precise and simple. Furthermore, since the applicator can pass into the deployed position, it can easily be used to perform other functions after the product has been applied, without the need to use another tool.

According to one alternative, the dispensing head comprises a mechanism for blocking translation of the applicator relative to the dispensing tube, the mechanism being active at least in the extended position.

The blocking mechanism enables safe immobilization of the applicator in the extended position, enabling precise use of the applicator.

According to one alternative, the blocking mechanism comprises a housing formed in either the dispensing tube or the applicator, and a blocking projection on the other among the dispensing tube and the applicator, the mechanism being active when the projection fits into the housing.

The supply of a blocking mechanism including a projection cooperating with a housing makes for simple fabrication and reversible blocking.

According to one alternative, the blocking mechanism is capable of blocking rotation of the applicator relative to the dispensing tube in the extended position.

Blocking of the applicator in rotation makes possible a number of functions requiring high precision, such as combing.

According to one alternative, the blocking mechanism is capable of enabling rotation of the applicator relative to the dispensing tube in the extended position.

Driving the applicator in rotation is positive for large application of the cosmetic product on the body surface.

According to one alternative, the mechanism for blocking translation of the applicator relative to the dispensing tube is active in the retracted position.

Blocking the applicator in translation in the retracted position guarantees that the applicator does not interfere with the tube during application of the product.

According to one alternative, the applicator comprises a comb or a roller, the roller being in the shape of a cylinder, an ogive or a ball.

Various functions can be performed due to the different types of applicator.

According to one alternative, the free end of the dispensing tube has a rounded shape. The rounded shape of the tube prevents the risk of injuries to the body surface.

According to one alternative, the applicator can be reversibly removed from a configuration engaged on the dispensing tube to a configuration detached from the dispensing tube.

Reversible disassembly of the applicator enables easy cleaning, or a change of the applicator type when necessary.

According to one alternative, the base comprises a cylindrical skirt defining an internal conduit, the base defining a shoulder on which the applicator stops in the retracted position.

The presence of an applicator stop in the retracted position holds it in this position and prevents any interference during application of the product. It can be held by clip fitting or crimping.

The invention also relates to a device for conditioning and applying a cosmetic product, comprising:

- a receptacle defining an inner volume for receiving cosmetic product, the receptacle comprising a neck, and

- a dispensing head like that defined herein above, the dispensing head being mounted on the neck.

The receptacle as defined above can be a tube.

The invention also relates to a method for applying cosmetic product on a surface of the body, including the following steps:

- providing a device as defined above, the applicator being in the retracted position;

- deposition of the cosmetic product by application of the free end of the dispensing tube on the body surface,

- axial translation of the applicator along the dispensing tube between the retracted position and the extended position, and

- application of the cosmetic product on the body surface using the applicator.

Application of the cosmetic product in the application method according to the invention can include rotational drive of the applicator around the dispensing tube.

The invention will be easier to understand after reading the following description, provided solely as an example, and with reference to the appended drawings, wherein:

- figure 1 is a simplified cross-sectional view of a first dispensing head according to the invention, when the applicator is in the retracted position;

- figure 2 is a simplified cross-sectional view of the dispensing head in figure 1 , the applicator being in its extended position; - figure 3 is a simplified cross-sectional view along plane Ill-Ill of the dispensing head in figure 2;

- figure 4 is a simplified cross-sectional view of a second dispensing head according to the invention, when the applicator is in the retracted position;

- figure 5 is a simplified cross-sectional view of the dispensing head in figure 4, the applicator being in its extended position;

- figure 6 is a simplified cross-sectional view along plane VI-VI of the dispensing head in figure 5;

- figure 7 is a diagrammatic view of another device according to the invention.

A cosmetic product conditioning and dispensing device 8 is illustrated diagrammatically on figures 1 to 3. The device 8 comprises a receptacle 9 and a first cosmetic product dispensing head 10 according to the invention.

The receptacle 9 delimits an inner volume for receiving cosmetic product. It comprises a neck 1 1 , through which the cosmetic product contained in the inner volume is extracted outside the receptacle 9 through the dispensing head 10.

The receptacle 9 may for example be a tube, a flask or a bottle. It contains a cosmetic care, make-up or coloring product.

The dispensing head 10 comprises a base 12 mounted in the neck 1 1 , a dispensing tube 14 projecting outwards from the base 12 and an applicator 16 engaged around the dispensing tube 14. In this example, the dispensing head 10 also comprises a mechanism 38 for selective blocking of the applicator 16 relative to the tube 14.

The base 12 comprises a cylindrical skirt 18 with axis A-A’, and a through wall 17 partially closing the cylindrical skirt 18 towards the exterior. The cylindrical skirt 18 defines an internal conduit 19 through which the cosmetic product flows.

Advantageously, the cylindrical skirt 18 has a thread 20 on its external surface. The thread 20 is then combined with a complementary thread provided on the neck 1 1 , such that the base 12 is mounted by screwing on the neck.

The through wall 17 extends substantially perpendicular to the A-A’ axis. The through wall 17 and the tube 14 define a shoulder 22.

Advantageously, the base 12 has a symmetry of revolution about the A-A’ axis.

The dispensing tube 14 projects from the base 12 up to a free end 24. The dispensing tube 14 defines a central product dispensing passage 26 that opens up on the input side in the inner conduit 19, and on the output side at the free end 24.

Advantageously, the free end 24 of the tube 14 has a rounded shape. It may for example be made of a plastic material, preferably polypropylene, polyethylene or elastomer. Advantageously, the inside diameter of the tube 14 at its free end 24 is less than 6 millimeters, and preferably less than 3 millimeters.

In this case, the dispensing tube 14 has a symmetry of revolution about a central axis. In the example shown on the figures, the central axis is coincident with the A-A' axis.

The tube can be made of a hard or flexible material or a bi-material comprising a part made of a hard material and a part made of a flexible material.

The applicator 16 is engaged around the dispensing tube 14. The applicator 16 comprises a cylindrical sleeve 27 defining a through opening 28 inside which the tube 14 is inserted. The through opening 28 has a cylindrical internal cross-sectional shape complementary to the external cross-section of the tube 14. It is centered on the A-A’ axis.

The applicator 16 extends along the A-A’ axis between a proximal end 30 closest to the base 12 and a distal end 32 further from the base 12.

In this example, the distal end 32 comprises a comb 34. The comb 34 advantageously comprises teeth 36 parallel to the through opening 28 of the applicator 16 uniformly distributed on the distal end.

In this case the applicator 16 also comprises an external proximal gripping skirt 37 converging towards the external sleeve 27 while going from the proximal end 30 towards the distal end 32.

For example, the applicator 16 is made of metal, ceramic, plastic and/or may be flocked.

The applicator 16 is movable in axial translation along the A-A' axis relative to the dispensing tube 14, between a retracted position that can be seen on figure 1 , and an extended position that can be seen on figure 2.

Advantageously, the movement distance of the applicator 16 along the A-A’ axis between the retracted position and the extended position is less than 15 millimeters and in particular is between 5 millimeters and 8 millimeters.

In the retracted position, the free end 24 of the dispensing tube 14 projects outside the applicator 16. Advantageously, the dispensing tube 14 projects outside the applicator 16 over a height of more than 3 millimeters along the A-A’ axis.

The free end 24 of the dispensing tube 14 is thus clear of the applicator 16, limiting risks of interference with the applicator 16 during application of product using the dispensing tube 14.

Similarly, in the retracted position, as can be seen on figure 1 , the proximal end 30 of the applicator 16 stops in contact with the shoulder 22 of the base 12. The presence of an applicator stop in the retracted position holds the applicator in this position and prevents any interference during application of the product. It can be held by clip fitting or crimping.

In the extended position, as can be seen on figure 2, the free end 24 fits inside the through opening 28 in the applicator 16. The orthogonal projection of the free end 24 of the dispensing tube 14 on the A-A' axis is then located between the orthogonal projection of the distal end 32 of the applicator 16 on the A-A' axis and the orthogonal projection of the proximal end 30 of the tube on the A-A' axis.

The blocking mechanism 38 prevents axial translation of the applicator 16 relative to the dispensing tube 14. The blocking mechanism 38 is active at least when the applicator 16 is in the extended position.

Advantageously, this translational blocking mechanism 38 is also active when the applicator 16 is in the retracted position.

However, the blocking mechanism 38 is inactive between the deployed position and the retracted position.

In this example, the blocking mechanism 38 comprises at least one housing 40 formed in the dispensing tube 14 and at least one blocking projection 42 projecting radially towards the A-A’ axis from the sleeve of the applicator 16.

As can be seen on figure 3, the housing 40 is an annular groove. The blocking mechanism 38 is active when the projection 42 fits into the housing 40.

In the example in figure 2, the blocking mechanism 38 comprises a proximal housing 41 located at the closest to the base 12 so that the applicator 16 can be blocked in the retracted position and a distal housing 43 located further from the base 12, so that the applicator 16 can be blocked in the extended position.

According to this example, the blocking mechanism 38 is capable of blocking rotation of the applicator 16 relative to the dispensing tube 14 in the extended position. Advantageously, this blocking in rotation is done by clamping. As an alternative, the housing 40 is not an annular groove, it is rather a hole complementary to the shape of the projection 42. Rotation can also be blocked by guide grooves.

Advantageously, the applicator 16 can be reversibly removed from a configuration engaged on the dispensing tube 14 to a configuration detached from the dispensing tube 14. The applicator 16 can thus be removed to wash it or to replace the applicator 16 and to engage another one on the dispensing tube 14, depending on desired finish.

Advantageously, applicators 16 of different types can be engaged on the tube 16 and can move along the tube 16 between a retracted position and a deployed position. A method of applying a cosmetic product on a body surface using the device 8 according to the invention will now be described.

For example, the body surface is a skin surface, a keratinic surface such as the eyelashes and hair.

Initially, the device 8 is supplied. The applicator 16 is initially in the retracted position.

The device 8 may be tilted. Under the effect of gravity and/or pressure on the receptacle 9, the cosmetic product is successively engaged through the internal conduit 19 of the skirt 18, then in the central dispensing passage 26 of the tube 14.

The user then applies the free end 24 of the dispensing tube 14 on the intended body surface. The user then forces the product out of the device 8 through the free end 24. Due to the reduced dimensions of the tube 14 at its free end 24, the cosmetic product is deposited with high precision on the body surface.

The user then moves the applicator 16 in translation along the A-A’ axis between the retracted position and the deployed position, advantageously until the blocking device 38 is activated in the extended position.

The user then applies the cosmetic product on the body surface using the applicator 16. In the example illustrated in figure 2, the user uses the comb 32 to distribute the cosmetic product on keratinic fibers, such as the eyelashes or hair.

Therefore the invention as described reduces the number of tools necessary for daily use in cosmetic product application routines. The dispensing head 10 according to the invention can thus deposit a cosmetic product precisely on a body surface, and then apply it without needing to change the tool.

The dispensing head 10 thus enables the user to save time during makeup routines.

An existing receptacle can also be used and the dispensing head 10 can be added to it directly.

During use, the dispensing head 10 remains attached to the receptacle containing the cosmetic product. Therefore there is no need for the user to manipulate small products such as caps that could get lost.

A second dispensing head 10 for a cosmetic product according to the invention is represented in figures 4 to 7.

The applicator 16 of the second dispensing head 10 is different from the applicator of the first dispensing head 10 in that it does not have a comb and in that it does have a roller 44. The roller 44 is advantageously in the form of a cylinder, an ogive or a ball. In this example, the blocking mechanism 38 is capable of allowing rotation of the applicator 16 relative to the dispensing tube 14 around the A-A’ axis in the extended position.

The application method then advantageously comprises a rotation drive step for the applicator 16 around the A-A’ axis by rolling on the body surface.

In the examples described above, the base 12 and the tube 14 are made from a single piece. As an alternative, the base 12 and the tube 14 are formed from two parts assembled to each other

In one alternative, the base 12 and the tube 14 of the dispensing head 10 are formed in a single piece with the neck 1 1 of the receptacle 9.

In another alternative, the dispensing head 10 is removable mounted on the neck 1 1 of the receptacle 8, to replace a cap or another dispensing system.

In another alternative, in the extended position, the free end 24 of the dispensing tube 14 is flush with the outlet of the through hole 28 of the applicator 16. The orthogonal projection of the distal end 32 of the applicator 16 on the A-A’ axis and the orthogonal projection of the free end 24 of the tube on the A-A’ axis are then coincident.

In another alternative, the blocking mechanism 38 comprises a housing 40 formed in the applicator 16 and at least one blocking projection 42 formed on the dispensing tube 14.
