Device for applying a cosmetic product stick

Abstract

An application device for applying a cosmetic product (e.g., a stick of cosmetic product). The application device has a main longitudinal axis and includes a container, a movable support, a drive screw, an actuating means, a connecting skirt. The container forms a reservoir of the cosmetic product and extends axially from an open lower bottom towards an upper dispensing opening. The movable support disposed axially inside the container and configured to be linked to the cosmetic product. The drive screw causes an axial displacement of the movable support inside the container. The actuating means for the drive screw. The actuating means and the connecting skirt forming a duct for the passage of the fluid cosmetic product from the outside towards the inside of the container when filling the container with cosmetic product.

1 . An application device for applying a cosmetic product, in particular a stick of cosmetic product, said application device having a main longitudinal axis and comprising:
 a container forming a reservoir of cosmetic product and extending axially from an open lower bottom towards an upper dispensing opening for dispensing the cosmetic product,   a support movable axially inside the container and configured to be linked to the cosmetic product,   a drive screw whose a rotational movement causes an axial displacement of the movable support inside the container,   an actuating means accessible to the user to cause the rotational movement of the drive screw and housed in the open lower bottom of the container,   a connecting skirt extending from the actuating means towards a lower end of the drive screw, the connecting skirt being funnel-shaped towards the drive screw,   
       the actuating means and the connecting skirt forming a duct for the passage of the fluid cosmetic product from the outside towards the inside of the container when filling the container with cosmetic product. 
     
     
         2 . The application device according to  claim 1 , wherein the connecting skirt and the drive screw are linked by at least one material bridge, the at least one material bridge being inclined towards the upper dispensing opening of the container. 
     
     
         3 . The application device according to  claim 1 , wherein the actuating means, the connecting skirt and the drive screw are integral and formed in one-part. 
     
     
         4 . The application device according to  claim 1 , wherein an upper edge of the connecting skirt comprises at least one indentation increasing the cross-sectional area through which the fluid cosmetic product passes when filling the container with cosmetic product. 
     
     
         5 . The application device according to  claim 4 , wherein the at least one material bridge is linked to the upper edge of the connecting skirt in an area without indentations. 
     
     
         6 . The application device according to  claim 5 , wherein the connecting skirt and the drive screw are linked by at least two material bridges, the at least two material bridges are linked to the upper edge of the connecting skirt between two adjacent indentations. 
     
     
         7 . The application device according to  claim 1 , wherein the actuating means is blocked axially in the open lower bottom of the container and free to rotate relative thereto. 
     
     
         8 . The application device according to  claim 1 , wherein the external end of the drive screw is ogive-shaped. 
     
     
         9 . The application device according to  claim 1 , wherein the movable support comprises a transverse wall equipped with openings for the passage of the fluid cosmetic product when filling the container with cosmetic product. 
     
     
         10 . The application device according to  claim 1 , wherein the movable support comprises a central skirt through which the drive screw passes, an internal wall of the central skirt of the movable support comprising a thread cooperating with a thread of the drive screw so that the rotational movement of the drive screw causes the axial displacement of the movable support inside the container. 
     
     
         11 . The application device according to  claim 10 , wherein an external wall of the central skirt of the movable support has a chamfer in the extension of the ogive shape of the lower end of the drive screw, when the movable support is in abutment with the ogive shape of the lower end of the drive screw. 
     
     
         12 . The application device as claimed in  claim 9 , wherein the transverse wall of the movable support is a grid. 
     
     
         13 . The application device according to  claim 12 , wherein the container is cylindrical and/or the grid is bean-shaped. 
     
     
         14 . The application device according to  claim 1 , wherein the actuating means has a circular cross-section and/or the container has an oblong cross-section. 
     
     
         15 . The application device according to  claim 1 , wherein the movable support has a cross-sectional shape similar to the cross-section of the container. 
     
     
         16 . The application device according to  claim 1 , wherein the actuating means is closed by a cap. 
     
     
         17 . The application device according to  claim 1 , made from a single material, the single material being polypropylene.
