Definitions

  • the present invention relates to the field of cosmetic product applicators.
  • Cosmetic products include in this document in particular all products for making up the skin, lips or integuments.
  • the applicator which is the subject of the present invention is also suitable for the application of care products, in particular liquid and paste care formulas, intended for application to the skin, lips and integuments.
  • care products in particular liquid and paste care formulas, intended for application to the skin, lips and integuments.
  • this also includes skincare products.
  • Cosmetic products must be applied to the skin evenly, in a thin, even layer. Ideally, the applicator should also allow a light massage of the area where the cosmetic product is applied. A feeling of freshness during application can also be sought.
  • Press tube type applicators include a flexible tube containing the product to be applied.
  • the tube must be pressed to cause the product to come out, via an orifice located on a relatively flat and generally metallic applicator area, in order to provide a sensation of freshness when applying. the application.
  • the quantity of product delivered with this type of applicator is imprecise because it depends on the force applied to the tube.
  • the spreading of the product using the applicator surface is done by friction on the skin, which does not allow a regular film of product to be deposited. Rubbing during application can also be aggressive or even irritating to the skin.
  • “Rod tip applicator” type applicators feature a metal rod with a rounded tip.
  • the rod and its tip must be immersed in the cosmetic product so that the tip is covered with the product.
  • the product is applied by rubbing the tip on the user's skin, or by depositing dots of product by repeated contact of the applicator on the skin. Just like with a squeeze tube type applicator, this does not allow for regular application of the product. Rubbing during application can also be aggressive or even irritating to the skin. In addition, product tends to get lodged between the rod and the tip and forms a clump which is not applied.
  • “roll-on” applicators generally comprise a flexible tube and a tip with a rotating mounted ball which loads product on its interior surface at the tip when the tube is squeezed. The surface of the ball loaded with product is then turned towards the outside of the tip, rolling on the user's skin, to allow the application of the product.
  • This type of applicator does not allow precise dosing of the product applied, the tube having to be squeezed to load the ball. The quality of the application depends on the orientation of the applicator, the tip must be oriented downwards to allow good application.
  • the risks of clogging of this type of applicator are significant: cosmetic product can clog the passage between the tube and the ball and thus prevent the latter from rolling freely, or even prevent the product from coming out of the tube.
  • the document FR3013197 presents an applicator whose tip has a shape of revolution and ridges.
  • the applicator can be moved into contact with the skin by sliding it over it with possibly a rotational movement of the application member on itself around a parallel axis to the longitudinal axis of the rod and/or perpendicular to this longitudinal axis. It is therefore up to the user to ensure an adequate application movement, using a gesture which is not easy to achieve, which does not guarantee regular application of the product.
  • the document EP3528660 discloses an applicator for a cosmetic product which comprises a gripping member extending along a longitudinal axis, a rod holder disposed in the gripping member, a rod secured to the rod holder and a cosmetic product application member carried by the rod, the rod holder being mounted movable in rotation around the longitudinal axis relative to the gripping member.
  • this applicator has certain disadvantages.
  • the product is likely to pass between the rod and the gripping member, which can hinder the rotation of the rod and lead to loss of product.
  • the configuration of the applicator makes it poorly suited to allowing massage during application, to the extent that a transverse force on the tip (application member) can bend the rod and easily deteriorate the connection in rotation of the rod holder with respect to the application member.
  • the present invention aims to provide a cosmetic product applicator, including liquid, viscous or pasty care products, allowing regular and continuous application of a precise dose of product on an application area having a defined surface, while allowing massage of the entire application area.
  • a cosmetic product applicator including liquid, viscous or pasty care products
  • Such an application must preferably be carried out in a simple and ergonomic manner, with obvious gestures for the user.
  • the invention relates to a cosmetic product applicator comprising a gripping element adapted to be grasped by a user and an application tip having a shape whose outer envelope is of revolution.
  • the applicator also comprises a rigid cylindrical core extending in a longitudinal direction, said core being rigidly fixed to the gripping element or formed in one piece with the gripping element, and a hollow rod mounted freely in rotation but fixed in translation on the core, the hollow rod extending longitudinally from the gripping element to the application tip.
  • the application tip is rigidly linked to the hollow rod or formed integrally with the hollow rod.
  • the core extends in the hollow rod over the entire length of the hollow rod measured in the longitudinal direction, with the possible exception of a connection zone between the hollow rod and the application tip .
  • a cosmetic product applicator in which the application tip is rotatable with respect to the gripping element of the applicator, in order to allow easy and regular application of the cosmetic product. Thanks to the configuration of the applicator which is the subject of the present invention, the application of a tangential force on the application tip, allowing massage of the application area, does not result in significant deformation of the applicator and in particular a significant bending of the core and the hollow stem.
  • the rotation mechanism using a core which extends over the entire or almost the entire length of the hollow rod rotatably mounted on the core, allows the application of such a tangential force massage on the tip without affecting the rotation mechanism. Finally, the risk of the rotation mechanism becoming clogged with cosmetic products is eliminated.
  • the core may be metallic. Any other suitable rigid material can alternatively be used.
  • the notion of rigid is understood as a resistance to bending sufficient to withstand a radial force exerted on the application tip during the application of cosmetic product, without bending too much, which would impair the free rotation of the tip and stem.
  • the application tip can be metallic or ceramic.
  • the hollow rod may be metallic.
  • the hollow rod and/or the application tip may be made of plastic material covered, on an exterior surface, with a metallic coating. In this case, the hollow rod may comprise a body made of plastic material, the body being covered with a metal sleeve.
  • a metal application tip offers a feeling of freshness to the user during application.
  • the hollow rod may include a perforated interior surface so as to limit the contact zones between said hollow rod and the core.
  • the applicator may comprise a first rotational guide member and a second rotational guide member, the first rotational guide member being interposed between the core and the hollow rod at a first end of the hollow rod, and the second rotating guide member being interposed between the core and the hollow rod at a second end of the hollow rod.
  • the first rotation guide member and the second rotation guide member may be bearings made of plastic material, ceramic or metal such as copper or copper alloy.
  • the first rotation guide member and the second rotation guide member may be bearings.
  • the applicator may include a single rotation guide member interposed between the core and the hollow rod.
  • the rotation guide member advantageously extends over the entire length, or at least a majority of the length, of the hollow rod.
  • the rotating guide members make it possible to limit the contact surface between the core and the hollow rod, which makes it possible to limit the friction likely to slow down the rotation of the hollow rod and the application tip. They also make it possible to guarantee the longitudinal position of the contact zones between the core and the hollow rod, which improves the capacity of the mechanism to function correctly despite the tangential force applied to the application tip. They finally make it possible to limit the noise during the relative rotation between the core and the hollow rod, in particular when the core and the hollow rod are both metallic.
  • the core may comprise a proximal end of the gripping element and an opposite distal end, the hollow rod and the application tip being blocked in translation with respect to the core at the level of said distal end of blade. This optimizes the blocking in translation of the hollow rod, the latter being interposed between the distal end of the core and the gripping element of the applicator.
  • the application tip may have relief patterns on its surface, preferably helical.
  • Raised designs can be any type of texture or any protruding design.
  • the helical patterns can in particular be beads or grooves. They allow better retention of the product on the surface of the application tip, and make it possible to generate a progressive grip of the applicator on the user's skin, as the application progresses. These patterns thus guide and “accompany” the user's gesture during the application of the cosmetic product.
  • the gripping element can form a cap suitable for closing the neck of a corresponding bottle.
  • the gripping element may comprise an internal structure and an external structure which covers said internal structure, the internal structure (23) comprising a longitudinal channel in which the core is inserted and fixed.
  • the applicator which is the subject of the present invention is thus particularly suitable for use with a bottle for which it serves as a cap.
  • the invention also relates to an assembly comprising a bottle and an applicator as defined above, in which the bottle contains the cosmetic product, the bottle comprising a neck adapted to be closed by the cap formed by the gripping element, so that, when the bottle is closed by said cap, the application tip is in contact with the cosmetic product.
  • the bottle may include a wringer, the wringer allowing the application tip to be wiped as it passes, so that a defined quantity of product is carried by the application tip after extraction of the applicator from the bottle.
  • FIG. 1 represents a cosmetic product applicator 1 according to one embodiment of the invention.
  • This applicator 1 comprises a gripping element 2 here formed by a cap adapted to be screwed onto a bottle of cosmetic product having a suitable neck.
  • the cap can be provided with a thread 21.

  • the general direction of extension of the applicator is called longitudinal.
  • the applicator comprises a core 3, which extends longitudinally along the axis A.
  • the core 3 is circular cylindrical. It can be metallic or made of plastic material. According to a preferred embodiment, the core 3 is metallic so as to have great rigidity. The core 3 therefore appears generally as an elongated cylindrical rod, of great length compared to its diameter.

  • the core 3 is rigidly fixed to the gripping element 2, at the level of the proximal end.
