Cosmetic product packaging device

Abstract

Device ( 1 ) for packaging a product, in particular a cosmetic product, comprising: —a receptacle ( 10 ) extending along an elevation axis (Z-Z′) and comprising an internal volume; —a lid ( 20 ) that is hinged with respect to said receptacle ( 10 ) between a closing position, in which said lid cooperates with the receptacle ( 10 ) and closes off access to the internal volume of said receptacle ( 10 ), and an opening position, in which said lid ( 20 ) is pivoted away from the receptacle ( 10 ) to allow access to said internal volume. The device comprises a stiffening member ( 40 ) mounted in the lid ( 20 ) and comprising at least one stiffening element ( 42 ) that extends along the elevation axis (Z-Z′) from the stiffening member ( 40 ) towards the lid ( 20 ) and rigidly secured to the lid ( 20 ).

1 . Device for packaging a product, in particular a cosmetic product, comprising:

         2 . Device according to  claim 1 , wherein the lid and/or the stiffening member is/are made of a polymer selected from the group comprising polyolefins, polyesters or styrene polymers. 
     
     
         3 . Device according to  claim 1 , wherein the stiffening member comprises a base and wherein the stiffening element extends along the elevation axis from an upper surface of the base towards a lower surface of an upper wall of the lid. 
     
     
         4 . Device according to  claim 3 , wherein the stiffening element is made as one piece with the base of the stiffening member. 
     
     
         5 . Device according to  claim 3 , wherein the stiffening element is mechanically secured to the lid. 
     
     
         6 . Device according to  claim 5 , wherein the stiffening element is secured to the lid by ultrasonic welding. 
     
     
         7 . Device according to  claim 1 , wherein the network of stiffening ribs forms a mesh comprising a plurality of contiguous shapes. 
     
     
         8 . Device according to  claim 7 , wherein the mesh comprises a plurality of contiguous polygonal shapes. 
     
     
         9 . Device according to  claim 7 , wherein the mesh is symmetrical with respect to a median plan passing through the centre of the stiffening member ( 40 ,  40 ′,  40 ″). 
     
     
         10 . Device according to  claim 7 , wherein the mesh is a grid comprising a plurality of contiguous quadrilaterals. 
     
     
         11 . Device according to  claim 10 , wherein the grid comprises a first group of substantially identical quadrilaterals and a second group of quadrilaterals arranged on each side of the first group, the quadrilaterals of the second group having different dimensions. 
     
     
         12 . Device according to  claim 7 , wherein the mesh comprises a plurality of contiguous hexagons. 
     
     
         13 . Device according to  claim 1 , wherein the network of stiffening ribs further comprises a central protrusion and a plurality of radial protrusions extending radially outwards from the central protrusion. 
     
     
         14 . Device according to  claim 13 , wherein the radial protrusions are spaced apart regularly around the central protrusion. 
     
     
         15 . Device according to  claim 1 , wherein the height of the stiffening element is adapted such that the outer surface of said stiffening element has a shape matching the shape of the inner surface of an upper wall of the lid. 
     
     
         16 . Device according to  claim 15 , wherein the height of the stiffening element increases gradually towards the centre of the stiffening element. 
     
     
         17 . Device according to  claim 15 , comprising a reflective surface mounted on a lower surface of the stiffening member, on the side opposite the stiffening element. 
     
     
         18 . Device according to  claim 15 , comprising a support member mounted in the internal volume of the receptacle and intended to receive at least one cosmetic product.
