  10. The applicator end piece (1) according to any one of the preceding claims, wherein the applicator end piece (1) comprises a sleeve (15) intended to be assembled to a stem (17), the sleeve (15) is continuous with the stationary end (3a) of the core (3).
  11. The applicator end piece (1) according to the preceding claim in combination with claim 2, wherein the ring (25) serves as the sleeve (15).
  12. The applicator end piece (1) according to any one of the preceding claims, wherein the cavity (5) has a predefined shape.
  13. The applicator end piece (1) according to any one of the preceding claims, wherein the core (3) is at least partly textured.
  14. The applicator end piece (1) according to any one of the preceding claims, wherein the applicator end piece (1) is a monolithic piece obtained without assembly and/or deformation and by additive manufacturing.
  15. An applicator assembly for a cosmetic product, comprising: - a container (11) comprising a body forming a reservoir intended to contain the cosmetic product, and - an applicator end piece (1) for the cosmetic product according to one of claims 1 to 12 adapted to be attached to the container (11), so that the applicator end piece (1) is housed inside the reservoir.
  16. A method for manufacturing an applicator end piece (1) for a cosmetic product according to any of claims 1 to 10, the method comprising: - a step of elaborating a digital model of the applicator end piece (1); - a step of manufacturing the applicator end piece (1) by means of the digital model.

Description

Technical field of the invention The invention relates to an applicator tip for cosmetic product, an applicator and an associated applicator assembly. The invention further relates to a method for manufacturing such an applicator tip. Technical background Applicator sets for cosmetic products are known, for example, for cosmetic products intended to be applied to a user's lips. These applicator sets include a container holding the cosmetic product and an applicator designed to be removably attached to the container. The container typically comprises a body, the body having walls that define a reservoir containing the cosmetic product, and a neck defining an opening through which the cosmetic product can be dispensed. The applicator typically comprises a cap designed to be fitted onto the neck, a stem extending from the cap, and an applicator tip attached to one free end of the stem. When the cap is fixed onto the neck of the bottle, the stem and applicator tip extend inside the reservoir. The applicator is immersed in the cosmetic product contained in the reservoir. To use the applicator, the user detaches the cap from the neck and extracts the applicator from the container. Common applicator tips typically feature a spatula-shaped area designed to make contact with the areas to be made up, particularly for loading cosmetic product. However, this spatula-shaped area usually only allows for localized application of cosmetic product, for example, to one lip at a time. The spatula also has an uncomfortable rigidity when pressure is applied to the area being made up. FR3104920 describes an applicator tip for cosmetic product extending along a longitudinal extension direction. The present invention aims to provide an applicator tip that allows a large area of a user, for example both lips, to be made up in a single application, while maintaining ease of use during makeup application. Summary of the invention Thus, the invention relates to an applicator tip for a cosmetic product extending along a longitudinal extension direction, called the main direction, and comprising a core extending from a fixed end to a free end and comprising a single branch forming a cavity, a first portion of the core surrounding at least a second portion of the core, the free end of the soul being mobile over a course delimited by the said first portion. In other words, the applicator tip has a core with flexibility due to the mobility of the free end. This flexibility provides comfort when applying the cosmetic product. This flexibility also allows the cavity volume to be varied, for example when passing over the opening of the reservoir containing the cosmetic product. This results in optimized wringing. The volume of the cavity can also vary during the application of the cosmetic product so that the user can choose the amount of cosmetic product released during application by varying the pressure exerted on the made-up surface. Furthermore, since the free end of the core is mobile but within a range limited by the aforementioned first portion, the wringing is limited and a sufficient quantity of cosmetic product remains in the cavity to be able to cover the entire desired surface without having to re-dip the applicator into the reservoir. This also helps to protect the free mobile end as it passes through the wringer, preventing it from being damaged. According to different embodiments of the invention, which may be considered together or separately: the soul presents at least one application-oriented part, The soul comprises a single branch, The soul defines a part of application, The cavity is flat. the cavity is open-ended, the cavity is through-hole, The first portion includes a ring that serves as a lateral stop at the free end. the second portion acts as a stop at the free end through cooperation during said movement the ring surrounds the free end, the ring surrounds the fixed end, The soul exhibits at least one return delimiting the cavity. The cavity has a variable volume. The movement of the free end changes the volume of the cavity. The soul crosses paths at at least one point of intersection. at least one crossing point is obtained by a helical winding of the core onto itself, the first portion is located at the fixed end, the first portion is located at the free end, The applicator tip includes a sleeve designed to be assembled to a rod; the sleeve is a continuation of the fixed end of the core. the ring acts as a sleeve. the cavity has a predefined shape, the soul is at least partly textured, The applicator tip is a monolithic part obtained without assembly and/or deformation and by additive manufacturing. The invention also relates to an applicator assembly for cosmetic products, comprising: a container comprising a body forming a reservoir intended to hold the cosmetic product, and an applicator tip as described above adapted to be fixed onto the container, so that the applicator tip is housed inside the reservoir.
