Wiper for a container containing a product, in particular a cosmetic product

Abstract

The wiper is intended to equip a container containing a product, in particular a cosmetic product. The wiper comprises a tubular coupling body ( 12 ), a wiping member ( 14 ) that is supported by the coupling body and defines a wiping orifice ( 16 ) with a passage section smaller than that of the coupling body, and at least one retaining bulge ( 18 ) protruding towards the outside from the coupling body. Said retaining bulge ( 18 ) has an outside diameter greater than or equal to the axial distance between the wiping orifice ( 16 ) of the wiping member and a frontal end face ( 12 a ) of the wiper which is situated axially on the side of said retaining bulge. The coupling body ( 12 ) comprises axially, between the frontal face ( 12 a ) and a bearing (face 18 a ) of said retaining bulge that is oriented axially towards the wiping member ( 14 ), at least one end portion ( 20 ) having a thickness that decreases in the direction of the frontal face ( 12 a ).

1 . Wiper intended to equip a storage container containing a product, in particular a cosmetic product, comprising a tubular coupling body, a wiping member that is supported by the coupling body and defines a wiping orifice with a passage section smaller than that of the coupling body, and at least one retaining bulge protruding towards the outside from the coupling body, the coupling body comprising axially, between a frontal end face of the wiper that is situated axially on the side of said retaining bulge and a bearing face of said retaining bulge that is oriented axially towards the wiping member, at least one end portion having a thickness that decreases in the direction of the frontal end face, characterized in that said retaining bulge has an outside diameter greater than or equal to the axial distance between the wiping orifice of the wiping member and the frontal end face of the wiper, said retaining bulge being disposed axially at a distance from the frontal end face, the frontal end face being set back transversely towards the inside with respect to said retaining bulge. 
     
     
         2 . Wiper according to  claim 1 , wherein the end portion of the coupling body has a thickness that decreases gradually. 
     
     
         3 . Wiper according to  claim 1 , wherein the thickness of the end portion of the coupling body is at a minimum at least at the frontal end face. 
     
     
         4 . Wiper according to  claim 1 , wherein the transverse space requirement of the coupling body is defined by said retaining bulge. 
     
     
         5 . Wiper according to  claim 1 , wherein the transverse space requirement of the coupling body is defined by a bearing flange of said body that extends obliquely from the frontal end face of the wiper. 
     
     
         6 . Wiper according to  claim 1 , wherein the coupling body has an outer surface from which said retaining bulge extends, said outer surface not having a point of inflection at least between said retaining bulge and the frontal end face. 
     
     
         7 . Wiper according to  claim 1 , wherein the coupling body has, between the frontal end face and said retaining bulge, an outside diameter greater than the outside diameter of said body between said retaining bulge and the wiping member. 
     
     
         8 . Wiper according to  claim 1 , wherein the bearing face of said retaining bulge extends radially. 
     
     
         9 . Wiper according to  claim 1 , wherein the bearing face of said retaining bulge extends obliquely on the side of the wiping member. 
     
     
         10 . Wiper according to  claim 1 , wherein said retaining bulge has an annular shape. 
     
     
         11 . Wiper according to  claim 1 , which is made in one piece, in particular by moulding. 
     
     
         12 . Device for packaging and applying a product, in particular a cosmetic product, comprising a storage container for said product that is equipped with a neck, an applicator that is provided with at least one applicator member and mounted in a removable manner between a withdrawing position in which said applicator member is situated inside the storage container and an application position in which the applicator is separated from said container, and a wiper according to any one of the preceding claims, which is fixed inside the neck of the storage container, the wiper being passed through by said applicator member of the applicator when said applicator is separated from the storage container, said retaining bulge of the wiper being engaged in at least one groove in the neck of the storage container, the frontal end face of the wiper being axially set back inside the neck with respect to a frontal end face of said neck. 
     
     
         13 . Device according to  claim 12 , wherein the width of the frontal end face of the wiper is less than or equal to the outside diameter of the distal end of the applicator member of the applicator. 
     
     
         14 . Device according to  claim 12 , wherein the outside diameter of the applicator member ( 46 ) of the applicator is greater than the inside diameter of the coupling body of the wiper, and less than the inside diameter of the neck of the storage container.
