Process, apparatus and moulding container for the production of compact powder cosmetic products with various shapes

Abstract

A process and an apparatus for the production of compact powder cosmetic products with various shapes is described, in which a moulding container ( 13 ) made of sintered porous material is utilised, which collects a semi-fluid cosmetic composition or slurry, which is subsequently dried and extracted from the container.

1 . Process for the production of compact powder cosmetic products with various shapes, comprising the stages of: 
 preparation of a semi-fluid cosmetic composition (slurry) ( 10 ),    pouring of the cosmetic composition ( 10 ) into a volumetric dose meter ( 12 ),    dosage of the cosmetic composition ( 10 ) inside a moulding container ( 13 ) provided with an opportunely shaped cavity ( 14 );    drying of the cosmetic composition ( 10 ) with consequent obtaining of a final cosmetic product ( 15 ),    extraction of the final cosmetic product ( 15 ) from the container ( 13 ), characterised in that said moulding container ( 13 ) is made of a sintered porous material ( 13 ) capable to allow the evaporation of the solvent through the walls of same container ( 13 ).    
     
     
         2 . Process according to  claim 1 , characterised in that said cosmetic composition ( 10 ) is in the form of dough, made up of a powdery cosmetic product dispersed in an opportune solvent.  
     
     
         3 . Process according to  claim 1 , characterised in that said sintered porous container ( 13 ) is of metallic material.  
     
     
         4 . Process according to  claim 1 , characterised in that said drying ( 4 ) takes place in an oven ( 20 ).  
     
     
         5 . Process according to  claim 1 , characterised in that said drying ( 4 ) is preceded by a stage of vacuum pack suction.  
     
     
         6 . Process according to  claim 1 , characterised in that the extraction ( 5 ) takes place by turning the container ( 13 ) upside-down.  
     
     
         7 . Apparatus for the production of compact powder cosmetic products with various shapes, comprising a volumetric dose meter ( 12 ) fillable with a semi-fluid cosmetic composition (slurry) ( 10 ), a porous material container ( 13 ) provided with an opportunely shaped cavity ( 14 ) fillable with said cosmetic composition ( 10 ), and drying means ( 16 ), characterised in that said container ( 13 ) is made up of a sintered porous material capable to allow the evaporation of the solvent through the walls of same container ( 13 ).  
     
     
         8 . Apparatus according to  claim 7 , characterised in that said volumetric dose meter ( 12 ) comprises a collection hopper ( 18 ) for the cosmetic composition ( 10 ), a dosing pump ( 19 ) and an outlet nozzle ( 20 ).  
     
     
         9 . Apparatus according to  claim 7 , characterised in that said sintered porous container ( 13 ) is made of metallic material.  
     
     
         10 . Apparatus according to  claim 7 , characterised in that said drying means consist of an oven ( 20 ).  
     
     
         11 . Moulding container for the production of compact powder cosmetic products with various shapes, characterized in that it is made up of a sintered porous material capable to allow the evaporation of the solvent through the walls of the same container ( 13 ).  
     
     
         12 . Moulding container according to  claim 11 , characterised in that it is made of metallic material.
