Applicator device for applying flowable product across a complex surface

Abstract

The present invention relates to an applicator device for a fluid or paste-like make-up and/or care product across a complex surface of the human body, having an elongated general outer shape axisymmetric about an XX axis; wherein the general outer shape thereof comprises a first rounded volume ( 1 ) connected to a second rounded volume ( 2 ) by an area ( 3 ) with a cross section smaller than the largest cross section of the first and the second volumes: where said device comprises at least one flexible longitudinal arch ( 10, 11 ) embedded in at least one point of a core ( 15 ) extending along the XX axis, where said at least one arch is suitable for defining with the core a product reservoir having a variable volume, resulting in the pumping of the product.

1 . Applicator device for applying a fluid or paste-like product of make-up and/or care type comprising an overall outer shape that is elongated and axisymmetrical around an axis XX, wherein the overall outer shape comprises a first convex volume connected to a second convex volume by an area with a cross-section smaller than the largest cross-section of the first and/or second volume, and at least one flexible longitudinal arch embedded in at least one point of a core extending along the axis XX, wherein the at least one arch is capable of defining with the core a product reservoir of variable volume, having a product pumping action. 
     
     
         2 . The applicator device according to  claim 1 , wherein the applicator device is in one piece. 
     
     
         3 . The applicator device according to  claim 1 , further comprising a tapered tip provided on a longitudinal end of the applicator device. 
     
     
         4 . The applicator device according to  claim 1 , further comprising several arches spaced radially around the core. 
     
     
         5 . The applicator device according to  claim 1 , wherein the at least one arch has a wave shape along the axis XX. 
     
     
         6 . The applicator device according to  claim 1 , wherein the core comprises an additional volume to the volume externally defined by the at least one arch ( 10 ,  11 ), and wherein the volume represents between 5% and 95% of the total volume of the device. 
     
     
         7 . The applicator device according to  claim 1 , further comprising spikes projecting opposite from the outer surface of the at least one arch and/or the core. 
     
     
         8 . The applicator device according to  claim 1 , further comprising at least one arch embedded in one point and at least one arch embedded in two points of the core. 
     
     
         9 . The applicator device according to  claim 1 , wherein the at least one arch is embedded in at least one longitudinal end of the core. 
     
     
         10 . The applicator device according to  claim 8 , wherein the arches embedded in a point have a length of between 70% and 95% of the total length of the device. 
     
     
         11 . The applicator device according to  claim 8 , wherein the arches embedded in a point have a free end oriented towards an interior of the volume of the device. 
     
     
         12 . The applicator device according to  claim 7 , wherein the spikes extend perpendicularly to the surface in which they are embedded. 
     
     
         13 . The applicator device according to  claim 1 , wherein the applicator device comprises between 1 and 36 arches. 
     
     
         14 . The applicator device according to  claim 1 , wherein the applicator device is obtained by a process of injection, dual-injection, co-injection, moulding, overmoulding, compression, casting, stereolithography, arrangement of material and/or addition of at least one layer of material. 
     
     
         15 . The applicator device according to  claim 1 , wherein the applicator device is made of a thermoplastic material, of vulcanisable elastomer or any technically equivalent material.
