Devices and methods of pressurized delivery of materials in cosmetic dispensers

Abstract

Cosmetic dispensers, and methods of use of such dispensers, for transferring material onto an applicator head through a transfer chamber and/or nozzle by applying force or pressure to the material.

What is claimed is: 
     
         1 . A cosmetic dispenser comprising:
 an applicator;   a storage compartment enclosing material; and   a chamber having one or more openings into a receiving area for at least a portion of the applicator and at least one orifice through which material from the storage compartment flows into the chamber,   wherein the storage compartment is a bladder.   
     
     
         2 . The cosmetic dispenser of  claim 1 , further comprising a pressurizer for causing material in the bladder to flow through said at least one orifice into the chamber. 
     
     
         3 . The cosmetic dispenser of  claim 2  wherein the pressurizer comprises a support adjacent at least one wall of the bladder. 
     
     
         4 . The cosmetic dispenser of  claim 3  wherein the pressurizer comprises said support and a lever. 
     
     
         5 . The cosmetic dispenser of  claim 2  wherein the pressurizer comprises at least one plunger. 
     
     
         6 . The cosmetic dispenser of  claim 2  wherein the chamber has a curved shape. 
     
     
         7 . The cosmetic dispenser of  claim 4  wherein the lever comprises a handle for the applicator, the applicator having a head at least partially insertable into the receiving area and a stem connecting the handle to the head in such position that, when the head is inserted into the receiving area, the handle is depressible to squeeze the bladder between the handle and said support. 
     
     
         8 . The cosmetic dispenser of  claim 2  wherein the pressurizer comprises a clam-shell housing within which the bladder is mounted, the housing having opposed sides such that when one of said sides is pressed toward the other of said sides, material in the bladder flows through said at least one orifice into the receiving area. 
     
     
         9 . The cosmetic dispenser of  claim 2  wherein the pressurizer comprises a roller movable along the bladder for pressing the bladder against a support adjacent the bladder. 
     
     
         10 . The cosmetic dispenser of  claim 9  wherein the roller is slidably movable along the bladder. 
     
     
         11 . The cosmetic dispenser of  claim 2  wherein the pressurizer comprises a roller connected to an end of the bladder and movable in a direction lengthwise of the ladder while rotating to roll up the bladder. 
     
     
         12 . A cosmetic dispenser comprising:
 an applicator;   a storage compartment enclosing a material, and   a chamber having at least one opening into a receiving area for at least a portion of the applicator and at least one orifice through which material from the storage compartment flows into the chamber,   further comprising a pressurizer for causing material in the storage compartment to flow through the at least one orifice into the chamber,   wherein the pressurizer comprises at least one plunger.   
     
     
         13 . The cosmetic dispenser of  claim 12  wherein the plunger comprises a lever. 
     
     
         14 . A cosmetic dispenser comprising:
 an applicator;   a storage compartment enclosing a material; and   a chamber having at least one opening into a receiving area for at least a portion of the applicator and at least one orifice through which material from the storage compartment flows into the chamber,   further comprising a pressurizer for causing material in the storage compartment to flow through the at least one orifice into the chamber;   wherein the pressurizer comprises a roller.
